Iphone 4S / iOS5 - Battery drain / issues - An idea Ihaven't seen anywhere yet (17th October 2011)....

Apple I have this problem

please fix it as fast as possible

although, i turned everything off its still drain my battery

I just got my 4S and ****.. my 3gS gave better battery life than it. Using the 3Gs with a few calls and about 1 hour of light gaming and surfing, resulted in 87% battery (1 hour,3 mins Usage; Standby 19 Hours, 55 mins).

The 4S, well, it's been drained by about 60%. I really dissapoiting that apple continue to remain silent and uncommittal of the fix.

I purchased two 4s Iphones (week ago or so). I upgraded mine from 3g to 4S. My wife started with the 4S. Long story short, mine drained like crazy (3 hours - 15% drop for me, something that took my wife's phone 24 hours). I drained my phone completely, recharged it (a bit 20% or so), backed everything up (itunes), erased all content and settings, and restored from itunes (see http://support.apple.com/kb/HT4137?viewlocale=en_US ) - problem resolved! I hope this helps others!!

Do you have 9A405 or 9A406 frimware? I have the same problems with 405 frimware and after upgrade to 406 my problems with battery drain are gone. Also noticed on 405 music player process was always on and sucking the bat, on 406 no music player in processes running in background

Please note, I am not an expert on this... I checked, and it reads 9A405. I noticed another thread dealing with the same issue. Interestingly, they seem to recommend not to restore... well, as said, it worked out well for me.

After being frustrated for a week because of the 4s battery issue, yesterday was my first taste of a brighter future... I was able to get 1 day of standby time and about 6.5 hours of usage time. That included several phone calls, text messages, 3d game playing, internet access, siri, maps, and I even used it for my wifi hotspot for about 15 minutes. Still I had hoped for at least charging my phone every other day, much like my 3g back then. It's good to note however, that I also performed 3 phone resets and 4 full cycle battery charge. Oh and I also disabled location services and notification for apps that I deemed unneccessary. I hope this could be better with the upcoming ios 5.1 update.

i just bought my iphone 4s 32gb but the battery drainage is so quick that i cant imagine. first i restored it from my itune back up and i thought that it might be due to the number off app so i restored it as a new one and lost every thing but the battery drainage still persists. i looked up everywhere in the support discussion and applied all possible solution but the problem is annoying... i even contact to the customer care mentioning my problem she suggested me the same that i already did....

being satisfied from the iphone 4 i decided to buy 4s but regretting...if apple wants to preserve its reputation of brand, it has to think otherwise beware....AN APPLE ROTS FROM WITHIN NOT FROM OUTSIDE (other competator)

For anyone new to the thread be sure to go through these steps to address the battery after updating to iOS 5.0.1:

1. Reset all settings (settings app-> general-> reset)

2 a. 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)

2 b. If you do not get the complete new setup screen with language setup and setup as new phone or restore from iTune/iCloud backup, be sure to go back to #1 and reset all settings again (it should happen the second time)

3. Turn off system location services timezone and iAd (settings -> location services -> system services)

4. Fully discharge battery (until you get the spinning wheel and it shuts off)

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!

If i were not to restore from icloud or itunes as you said it will copy back the corrupt settings, then how am i able to retain my datas that were stored previously (eg. contacts,etc)?

Reezuan,

I am not sure what David really means.... But the procedure is to restore as new. Add back things like settings, email accounts... etc by hand. This is the stuff you would get back by doing a restore from a backup. It should only take a few minutes to add back this stuff manually.

Then you can sync from the the iCloud or iTunes and not re-incorporate past bad code and settings.

What you don't want to do is restore a backup from iTunes or the iCloud. If you do a sync you will just get back your phonebook, apps, calendar, music...etc and not bad code or settings as you might from doing a restore from a backup.

Sorry if this is not really clear but it is late in my neck of the woods.

CAVEAT- make sure you do a sync to iTunes or the cloud which ever you normally use before doing any of the things mentioned above. That way you will have your phonebook... etc saved away. By the way terminology gets weird a sync and a backup are not the same animals. A backup is something that contains iPhone settings and iOS data files and such. A sync only deals with your "stuff" i.e. Apps, Music, Phonebook, calendar...etc.

Try this it workd for me

I hope this wil help you and every one who faces same battery drain issue

How to dramatically improve Iphone 4S Battery Life

I have been fighting battery drain since ios 5 came out. Totally disgusted. I have tried everything possible to fix the problem including ordering two replacement 4s phones. I found on-line a recommendation to upgrade firmware to 9A406 (i did have 9A405). This update has not been sent out from Apple to the masses but it is available if you google it. I installed in at 7pm yesterday and as of right now 9:20 pm 26 hours later I have 20% left! Yeah!

Give it a try - i hope it works for you!

9A406 = 5.01 that update has been around since Nov 2011

I am at 3% remaining battery with only 39 minutes usage and 7 hours standby. The horriible thing is I have *everything* off, I have done all imaginable kinds of restore, set it up as a new phone, and have even gotten the phone exchanged. Still dead when I wake up in the morning. This is so depressing and I am regretting buying this phone.

Apple have 2 version of 5.0.1 for 4S (9a405 & 9a406) I believe have have 9a405...download 9a406 and upgrade manually. That's should fix the problem...

good luck,
