Hi all,
Needing a little bit of advice - not sure if I am doing something wrong.
When I chose my MP3 player, I originally didn't want an i-Pod due to the fact I'd heard the battery life was rubbish. When we went to the shop to buy the Sony MP3 I wanted, we were basically talked into the i-Pod by a very enthusiastic salesman who was a hardcore i-Pod fan.
I've got the new 30gig video i-Pod and he told me that although it advertises around 20hrs battery life he said I could ideally expect between 6-10hrs of CONTINUOUS PLAY on the battery, which was fine.
However I am finding I am getting approx 1.5hrs of continuous play at the very most before my battery goes into the red from full.
Is this due to something I am doing wrong, or are all i-Pods generally like this? Or do you think its a problem with mine?
Any advice would be appreciated!!From new, the iPod battery can take time getting to full potential. There are a lot of factors that affect battery usage such as what size your music files are, how often you use the click wheel or the backlight etc. As far as battery life goes, the hours Apple quotes are based on continual play of music files, AAC 128kbps file format, no backlight and no access via the scroll wheel during play. How long you get from your battery really depends on how you are using your iPod.

Sudden Onset of Constant Fan and rubbish battery life....
2 days ago my fan came on constantly and, as a result - I get only about 2 hours of battery life with the BlackBook on with NO progs running (not even airport).
Tried everything - SMC Reset, Activity Monitor - the works. BlackBook only 14 months old so out of warranty but wondering what I can do. Tried running battery down then recharging it.
Would be grateful for your advice - the noise is deafening and the battery is more than annoying me as I used to get 4-5 hours!What does Activity Monitor show? Anything? Do the same issues occur in a separate user account?
Are you certain you reset the SMC properly?

Can someone tell me when Apple will release an upgrade for devices other than iphone4S - I have an iphone4 and need it to work properly!
I have the same problem with my iPad 1 and 2.
iPad 1:
Since updating to 4.3 the battery life drains like 1% per minute when using internet or playing online games (like Smurfs'Village).
Since updating to 4.3.1 the battery drains a bit less faster but it's still not as good as before 4.3.
iPad 2:
I bought iPad 2 last friday and upgraded to 4.3.1 when i connected it to my computer and the battery life drain really fast when surfing the internet or playing online games.
A friend of mine is having the same problem with his iPad 2 and is even thinking of returning it if it's not seen to it fast.
I tried deactivating Ping in the Restrictions section bu that did nothing to my first iPad. I'm still testing that with the second.
Is there something else that can be done? Am I missing something?
Thank you for your help! -
Battery LIfe in Macbook Pro 2012- complete joke
Hi All, just got a new macbook pro for xmas. It was a refurbushed one from July 2012 which comes with warranty etc etc.
Firstly am pretty annoyed as think Appple is really going downhill fast (iphone 5 have seem issues with battery but service in hk ***). The battery on this new computer has a complete life span on 2.42hours. This is with only this webpage open so thus my concern. It is just crap. That cant be right i am guessing as the website says up to 7hrs.
I timed it to take 16% of the full charged battery within 20mins using nothing but very light web browser.
I used to have a macbook pro 2010 which was great but this just seems rubbish. I live in hong kong though and find any issue you have is not recieved with the neccessary service that i am used to in my home country in Australia. They will just tell me to take it to the repair centre. Personally think this is unacceptable as why should i have to do all the leg work on there new computer which is faulty.
Is this a common problem re battery? Also am i in my rights to the peopleat the store that it simply isnt god enough and they should do the legwork rather then me having to take it to the service centre.(i brought it off the apple online store)Yes the 2010 MBPs were the most efficient MBPs made in terms of battery life (and the 10.6 OS). I have one. The subsequent quad core/10.7 OS changed that some what with a lesser battery life span. I also have a 2011 MBP.
I would say that 2,42 hrs would be disappointing to me as well for light duty CPU loads. Now understand that Apples battery life claims are based on Ebenezer Scrooge setting. My rule of thumb that for my 'normal' use will be about 2/3s of Apples advertised times.
I do note your general satisfaction, but as a fellow user there is nothing that I can do to assist you in that area All I can do is point you to these two articles that may give some strategies where you may be able to increase the battery life:

Ok so it seems that the v20 firmware for the n95 is susposed to improve battery life! Well .. . thats aload of rubbish!! I have just updated to v20 from v11 r12 and it now seems my battery lasts about 7 hours max! when i had version 11 or 12 it lasted about 3 days! Anyone having the same problem?
I dont see any improvement on the battery life of my N95-2 with the new fw. Usually it lasts for 2-2.5 days.

Have this C3-01 since 10 days now and the battery life is only about 48 hours.
I charged the mobile 4 times since after it was empty each time.
Closed GPRS, G3 (working only on GSM), Wifi...
Any idea or does it need a soft upgrade ?
Call time was last charge 15 minutes, rest stand-byTerrible - the only word.
Terrible phone, terrible battery, terrible functions, terrible support.
One year old - and two touch screens have already died and been replaced.
The phone self-activates from "locked" under weird and unexpected conditions.
The battery (original, now one year old, from new with phone) lasts just 14 hours without making a single call.
Have checked Nokia S.C and every store in every mall in Dubai and Fujeirah - none in stock.
On occasion the base of the phone (battery area) heats up, as if on rapid charge.
Has fried the micro SD memory chip and all data lost.
Checked on web - and a firmware update exists.
Checked with Dubai Nokia Service Centre when last new touchscreen fitted but "Latest update already installed"
Rubbish, rubbish, rubbish!
Cannot understand how Nokia can make such a huge error in releasing junk.
Ford had their "Edsel" in the US.
Mostly that was over-engineered.
This C3-01 is simply a disaster on all counts.
Incredible!! -
I have just upgraded to a 6230i from a 6310i and I am extremely disappointed in the battery performance. Nokia claim on the box 240 hours standby and in the specs on the web 150-300 hours. I am getting significantly less.
With the battery fully charged; basic screen saver with a time-out of 5 seconds, power-save on, and using to send just 2 text each of 20 characters I get less than 60 hours.
This is a brand new phone, which has had its battery charged 4 times as recommended (ie. fully discharged and then fully recharged for no more than 4 hours).
I believe that less than 60 hours is unacceptable.
Can anyone please advise?
Many thanks

11:04 AMHi Megadod,
Again, many thanks for the feedback.
Following your feedback and that from Club Nokia I returned the unit to Vodafone. They were extremely reluctant to exchange it because of the battery's performance, because, according to them, the battery was performing correctly. Nevertheless I pursued the issue and they finally agreed.
However, I have to confess to being a little confused.
According to Club Nokia and your good self, I should be getting significantly more battery life (Club Nokia say at least 150 hours). Vodafone say this is rubbish and that the best I can expect is 2 days, perhaps 3 in the very, very best circumstances.
So why is Nokia claiming 3 times as much as Vodafone?
Since Nokia are the manufacturers I tend to believe them more than Vodafone. But Vodafone were adamant; 2-3 days at most. Apparently, even they shop demo which is never used to make/receive a call only last 2 days!
Because the difference in claims in so staggering, I would really like to pursue this issue and as such, am wondering if you can offer any advise?
Best regards

Possible Internet Tethering/Battery Life Issue
When either Cellular Data is turned Off, or Airplane Mode is turned On, Internet Tethering (Settings>General>Network) appears to have some process that runs continually in the background (evident by continuously spinning wheel next to the option). The running process has a demonstratively negative impact on battery life (1/3 reduction in ~ 30 mins). The Apple Genius at my local Apple Store and I verified the issue on numerous iPhone 4s that were on display. Turning Cellular Data On and ensuring the phone is not in Airplane Mode stops the activity. But obviously that defeats the purpose of having those options.
So if you are experiencing poor battery life, this might be your issue.

My new ipod touch's Battery life is extremely short
I bought 10 days ago the latest iPod touch and it is getting very poor battery life.
Even without using multitasking and with having notifications turned off, it is running from full to empty in less than two hours.
What is it that I have to do between all the things people recomend?
- Reset Network Settings
- set it up as a new device with no apps
- Powering off every night
- Shutting down Wi-fi all the time
- turning off push mail, notifications, etc
- Turning off "Location Services"
I've tried doing the lasts 4 things and nothing improved..
Or is it just because it's new and in the future it'll work longer?
Thanks you all for your useful answers!You might check out this thread for possible help.

General info and specs
First, take a look Apple's battery tips, info and specs(obligatory reading for all Iphone 4S users - read it once and for all):
http://www.apple.com/batteries/iphone.html
http://www.apple.com/batteries/
... you didn't read it? loll Always remember this i.e. the definition of "usage":
Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
I'm still not convinced you read the links so here's what Apple has to say in terms of fine tuning your battery life:
Optimize your settings
Depending on how they are configured, a few features may decrease your iPhone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iOS 5.0 or later and may help extend your battery life.
Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.
Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.
Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ and tap Flat.
Usage specs for the 4S - http://www.apple.com/iphone/specs.html:
Talk time: Up to 8 hours (12.5% per hour drain) on 3G, up to 14 hours (7.1% per hour drain) on 2G (GSM)
Standby time: Up to 200 hours (0.5% per hour drain)
Internet use: Up to 6 hours on 3G (16.6% per hour drain), up to 9 hours (11.1% per hour drain) on Wi-Fi
Video playback: Up to 10 hours (10% per hour drain)
Audio playback: Up to 40 hours (2.5% per hour drain)
So a scenario of normal usage could be for example: 4 heavy hours of 3G internet browsing (66.4%), with one hour of call on 3G (12.5%) and 22 hours of standby (11%) = 100%
A battery life issue is a problem where the drain is really out of spec either during usage or standby or both. For example, multi-% per minute drain during usage or a 10% drain per hour during standby is problematic. Browsing the internet on 3G during one hour and losing 16-17% is not.
Apple's test methodology for claiming the specs:

Procedures
davidch tips (reset+full discharge recharge):
Go through these steps to address the battery after updating to iOS 5.0.1:
1. Reset all settings (settings app-> general-> reset)
2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
3. Turn off system location services timezone and iAd
4. Fully discharge battery (tilll it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
In my experience this improves the Standby battery drain issue significantly in most cases. It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple. Good Luck!
ram130's variant of davidch i.e. additional steps:
Now using davidch original steps and attaching the tweaks I made to get me more usage. As shown on page 29.

4. Fully discharge battery (till it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
6. Disable Siri 'Raise To Speak' and REBOOT *( if possible use another camera to verify the infrared is off after the reboot).
7. Set emails, icloud and calendars to fetch. ** test. Mines on hourly.
8. If your in a no signal and your phone is saying "Searching..." even after 10mins, reboot while in that area and after 1-2min it should say "No Service". This mainly applies to Verizon customers and improve battery life in these areas.
9. *optional* Goto Settings > General > Network and you will see "Hotspot.." loading something, wait a few seconds and it should say "setup personal hotspot" then exit out.
* I notice a great improvement after disabling this and rebooting. This increased my "screen on" usage or at least helped it. Make the change.
** I have not tested push yet to narrow down the drain but I had this change on my phone. I believe exchange push is responsible for some stand by drain. As for icloud, haven't notice much of a difference. Just try it for a day. My email still came in fast most times. Again still testing, will report back on these..
buxbuster tips(wifi sync, iCloud):
These are my own tested workarounds that worked for my iPhone 4S and seemed to have worked for others as well :
Workaround number 1. Deselect wifi-sync in iTunes and press sync.
If that doesn't work try :
Workaround number 2 : Remove iCloud, reset network settings. ( I guess this won't work for you since you don't have it enabled ).
If both workarounds fail, you can always try to completely wipe your phone. That also solved some of the cases out there.
rolandomerida tips - i.e. buxbuster and additional steps:
Finally, I solved the syncing error loop. My contacts are syncing flawessly again between my devices and iCloud, and yes, the battery stopped draining, which is the main topic here.
I followed instructions from buxbuster (check his workaround a few pages up!) and an additional BIG step to restore contacts and syncing, as seen in a MacRumors forum.
This is what I did:
1. Make a backup of your Address Book, using the vCard option (or both, it doesn't hurt). Save it for later.
2. In your iPhone, delete iCloud account. When it asks, accept both: delete AND delete from my iPhone.
3. Reset network settings. The iPhone will restart, then will ask you to unlock the SIM card.
4.Turn Wi-Fi on.
5. Add the iCloud account again.
That's for Buxbuster's workaround. For some, it might work just like that. My iPhone repopulated from iCloud after step 5, but I still had that "server error" on iCloud. I had to do some extra steps, since my Mac was not syncing to iCloud and couldn't edit anything on my Mac or iCloud. Syncing back had to be fixed, too. If not, the syncing loop would continue from my iPhone, and the battery would drain awfully again.
1. In System Preferences -> iCloud, I turned Contacts off. I chose "keep on My Mac" those contacts, but I got an empty Address Book after a while. And a few minutes later, iCloud contacts were empty and my iPhone also. It is scary at first! Now, before importing that vCard backup...
2. Turn Wi-Fi off. This is important, since your contact-empty iCloud will attempt to wipe your Address Book from your Mac in seconds after importing.
3. Import your vCard backup to Address Book. Just drag it to your blank Address Book window; it asks if you want to import "x" number of cards. Of course, say yes.
4. Turn Wi-Fi on, and then iCloud contacts on again (System Preferences -> iCloud). It will offer to merge your newly populated Address Book with iCloud (which is empty at this point). It should upload every single contact to iCloud, and then to your iDevices. If not, a fifth step would be to import the vCard file to iCloud, but it shouldn't be necessary.
So, with iCloud syncing working correctly, there is no battery draining! Again, that was my particular issue.
I can't tell if this is the single answer to the widely spread battery draining problem, but it sure can be fixed with these workarounds, and yes, Apple should address the problem with a future update, for we affected customers don't need workarounds in the first place
This is the MacRumors discussion:

And dont' forget to check buxbuster's fix, video, and THANK him!
Miless tips (full 800mb release of 5.0.1 and sanitizing a restore):
As for 4S battery life. Try doing this,
1. Settings>Location Service ... disable all location services you do not need. In particularly Facebook because it drains the battery a lot.
Scroll down to the bottom at Settings>Location services>System Services ... Disable Setting Time zone, location based iAds, Diagnostic & Usage.
2. Settings>Notification>Calendar ... turn off the Notification Centre.
3. Settings>General>Reset ... do Reset All Settings. Doing this will not wipe out your iPhone. It will just Reset the network settings, location warning, keyboard dictionary, etc... but it will clear up some corrupted data there. Generally this will help.
Try these 3 steps first... if it still drains a lot, try the following,
4. Drain your battery down to 1%. Then charge it up using USB from PC ... not the charger. The charger output 1.0 A ( x 5V from USB ... you get 5W power). From PC, output is only 0.5A x 5V = 2.5W power. Charging is slower but trickle charge 4S helps the battery retain its charge better. I think it takes about 3-3.5 hours to charge full from USB/PC compared to slightly below 2 hours using iPhone charger.
If after doing the above still could not solve your battery issues (mine with iOS 5.0 was ok up to step 4, but not iOS 5.0.1).... plug you iPhone to a charger (any charger), from iPhone, access your iCloud ... set it up if you havent. Back up your iPhone data to iCloud. if you do not have enough storage (only 5GB is free), go to details and select the apps you need its data backup, choose only those you really need and leave those unnecessary ones out. Back up your camera roll to your PC/Mac manually as it could be too big to backup to iCloud.... once you have it setup, make sure you are on Wifi ... tap backup to iCloud from your iPhone. It will take a while if the file is huge.
Once backup to iCloud is completed, plug your iPhone to PC/Mac and launch iTunes 10.5.1 (make sure you have 10.5.1)
Click Restore. It will automatically initiate a download of iOS 5.0.1 ipsw for iPhone 4S. Wait for the whole process to finish, ie. download, restore software/firmware.
Once its done, do not set up your iPhone from iTunes. Set it up on your iPhone. Go through the selection. When prompted, select restore from iCloud (from your iphone backup earlier). Keep your iphone plugged into iTunes while restoring backup from iCloud. Because while restoring from iClouds, some data will be synced from iTunes if you plug in, e.g. music, video, etc... unless you bought these content from iTunes store. Apps will be downloaded from App Store from the cloud.
Once it's all done restored. Turn off your iPhone,.. and turn it on again.
Now, hopefully your battery wont be draining so fast anymore. Usually it wont after this. But you need to charge your battery at least 4-5 cycles to stabilize the charge on the battery. I dont know why... but battery life seems to get better and better for me after a few charge cycles after all the above work.
Good luck. Let us know if it works for you.
W. Raider tips (Sirii):
Bottom line for me of things that helped battery life are:
1. Turing off Siri and Rebooting the phone by holding the Home button and Top button down, ignoring the slider, until the phone shut down. (turn off Siri, reboot, and check top front of iPhone 4S against a lesser camera like the front-facing camera on an iPad2 - making sure the IR sensor is off)
2. Fully draining the battery, meaning using the phone until it shuts itself off from a drained battery and then recharging it to 100% about 4, maybe 5 times. I charged it both with a Mac and a wall charger.
Hope this is helpful!
Comments
jmm514 remarks (Twitter):
I may have found something. I had Twitter disabled in my notifications, but got a tweet today that popped up on my home screen. Didn't know I had this enabled. At the bottom of the Twitter notification settings is the home scrren toggle. Since disabling this, battery life seems better. Considering there is no setting for frequency of checking for tweets, it appears the phone is continually connecting to wifi to check for new tweets.
tmksnyder comments (notifications, corrupt data in iCloud):
For me, I found my iphone on wifi mysteriously connecting to my mac. I eventually narrowed it down to the Apple Move Trailers app which keeps a file in iCloud. The phone was trying to sync the file with the mac in the background even when the Movie Trailers app was closed (hitting the red x). Based on my macosx logs the iCloud process that was trying to sync was working directly between the phone and the mac without using itunes by connecting to an https address hosted on the phone. It was connecting every 3 minutes and failing (while phone was awake or awake during during a notification). I also found that iCloud control panel on OSX would error if I tried to delete the file. I fixed it by removing the App and doing a hard reset which stopped the sync. I probably could have turned off iCloud document sync in the phone but didn't think of that. My battery life has greatly improved while at home on wifi. I am now at 28 hrs standby, 2 hrs 20 minutes of usage, and 68% battery. It was ok before where I could get 20-30 hrs standby and 6 -8 hrs usage. My usage today was phone calls, 3g surfing, and music via bluetooth in the car.
I also found even with Itunes iMatch, if I mass updated tages, art work etc, it would hit the phone on wifi even in standby. I was amazed. Granted if I am not doing updates, Match won't hot the phone so this was a once in awhile event. I could drop my percentage by 5-10% in a matter of minutes when doing updates. I think a lot of our problems are background processes, associated with iCloud, notification, and apps. More features means more battery. I think the key thing is to keep track of what has recently been added or changed if battery life gets worse all of a sudden. It may be an app that was recently installed and if possible you may want to completely remove it and not just quit it.
With twitter, i think it uses push notifications so it doesn't need to be running and actively poll on the phone. For instance , if i quit the mail app, i still will get mail notifications and can swipe the message and load mail. Apple Push Notifications servics maintain the connection to the phone and there are likely pings or connection checks that occur for the service on an os level not an app level. This minimizes the load so there arent a bunch of apps all runing and constantly checking. The notification service , if it is contacted from twitter or another service with data, will check the settings you have registered to the with the apple push service and send the notification to your phone. No matter what, there is a drain with notifications. M hunch is once one application is configured to receive notifications, connection checking occurs betwen the push service and the phone so it knows where it is on the network. If it is implemented correctly, these checks arent frequent if you are still and more frequent as you move. The other drain is for when the noification hits and is processsed. If i get 9 emails over night, my screen just popped up for 20 seconds or so to process each message using battery. I would even think that just go from low power to turning n the screen uses more juice than if the device was already on and i get the message. On nights I get no notifications, I see a 3 or 4 percent drop. On nights with a number of notifications, i have seen up to a 10 percent drop. Besides notifications, wifi sync and icloud will poll on the local network and use up battery if the host computer is on and running itunes or trying to sync a data file that is corrupt (which i had with the apple movie trailers app causing my phone to drain). For me turning off wifi sync and remving a corrupt file in icloud solved my battery issues and I get over 24 hrs of standby with 6 to 9 hrs of use and this is with all the normal location services and push serivices turned on.
See http://developer.apple.com/library/mac/ipad/#documentation/NetworkingInternet/Co nceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html for more info. I think it has a good overview of how the notifications work.Well seems like that rumor of iOS 5.0.1 is finally gone the way of the dogs since developers got a beta of 5.1. So as stated earlier in the master discussion-> I suspect if you are filling up this thread with false post or creating a master set of links to various post that are unreliable you are wasting your time. Press is not going to touch the story due to poor or inaccurate sources which may be links from the master thread. This can include inaccurate information, combination of conflicting post or postings from users which may not own the device. Reputable press organizations have policies that require discloser and strict rules about what is a reliable source for a story. It is clear that many of the post in the master thread, which are links presented here are questionable.
Sorry to say that postings taken without any analysis of their totality have been propagated via various sites, for example sites such as http://www.2012federalbudget(dot)com. (Do not visit but I suspect that this is not the 2012 federal-budget site you would expect based on analysis of the records. There are plenty of sites like http://www.2012federalbudget(dot)com propagating questionable post in these threads.) One site for example in the discussion thread used a self signed certificate, the site had a log in to allow users to enter their OpenID. Seems many of these sites are pop and drop drupel configurations.
So remember this is how the really bad rumor of iOS 5.0.2 got started, the 5.1 memory leak issue, iCloud Issues, call quality, address book, etc.
Some of the postings have been very comical, I think the latest now is a dropbox issue. Seems that the length of the previous thread has resulted in various app engines of some proxy servers/tools reaching their limits.
So I would make sure to know the source of any information you link to. Make sure you avoid entering any information to outside links such as OpenID or Apple ID, these are big prize items for anyone with malicious intent. If you have issues and are a valid user contact APPLE CARE. (Note link is using McAfee Secure Short URL Service, and is https.)

The original solution still represents a high level of success for users having any battery issues.
Install 5.0.1 on your iPhone 4s. Some users posting they are still using older versions, bad fake serial numbers, etc.
Make sure your device can run iOS 5.0.1 and is not altered.
Make sure you use a new Sim, not some cut down version which many users admit to doing. (Again, worth confirming what people are posting.)
Reset the device doing a hard reset and software reset.
Let battery drain and then charge for the full cycle, which is 24 hours.
I think you will find you will get the battery usage that APPLE has stated for the device.
Best of luck, stay safe and thanks -
How do I maximise battery life on iphone 5s
I have just got an iphone 5s and the battery life is terrible. With my 4s I used to double click the home button then I could close down each app fully as they showed up in a row and I could press an x. I cant seem to do this with the 5s. Please help, its lasted 9 hrs since charging and I ve been asleep for most of them!!! I tried Apple support chat but after over 30 mins I didnt get a reply.
To shut down apps double-click the home button then swipe the app screen shot upwards. However, very few apps actually run in the background.
The list of apps you see when double-clicking the home button is only a list of recently used apps, it is NOT a list of all running apps.
Battery life will improve over the next days and weeks as the battery is used. -
After iOS 8 update wifi is so slow and battery life is much worse
After installing iOS8 on my 5s the wifi and 3G has slowed remarkably down. The facebook app now doesn't refresh unless I turn the phone off and on again and safari takes an age to load it's pages. Also the battery life is even worse than before. I used the maps yesterday for 1.5 hours for a trip and it took me from full battery down to 10% in that time. This is really irritating me now, will it be fixed?
Like you I have a 4S running on iOS 8, and since the upgrade to 8 my battery drains like crazy. I'm not experiencing the wifi issues that some of the other posters are having, but the rapid battery drain seems to be a common issue. I keep hoping Apple will address this with their updates for iOS 8, but it always seems to be overlooked.
