Q: iPhone 4s Battery Life?

I am taking My Iphone 4s into apple today, booked a genius bar appointment it is getting ridiculous i looked at my usage stats last night and i was on 75% on 16 minutes usage and 51 minutes standby and that usage was facebook and music

Don't worry about genius bar. Just take it to the till and they will exchange as it is within 14 days

I am having massive drops in battery and have tried everything suggested  here but to no avail. It's a pity as I sold a prefectly functioning 4 for this. Will give it a week for Apple to resolve it/comment and if not I will return it.  Not good Apple.

Got a 4S after a 4. Battery is worse with the same amount of usage. Changed all the settings as advised in previous comments and several different blogs. After trying everything with no success I completed a DFU restore of the phone. After doing so I can see no improvements as of yet in the battery life. Very disappointed.

When my iPhone 4S 32GB pre-order arrived the battery was completely dead, I got all excited about setting it up and had to wait an additional 30 minutes to get enough charge to boot it.  This is unusual as all the iPhones I've ever setup for myself or for users in my company have all come pre-charged. 

I had battery issues for the first whole day, lost 50% in just 4 or 5 hours of mostly standby use.  The second day (after a full charge cycle) was much better.  I lost 10% in 5 hours.  On subsequent days it seems that my battery drainage has gone back up slightly, but not terrible.  I lose about 16% in 4.5 hours.  It still seems high to me considering my phone is in my pocket or at my desk, connected to wifi, no apps running. 

I've had issues in the past starting with 4.3 where restoring backups from previous phones causes bad battery performance and a host of other issues.  I don't want to setup my phone as a new device and lose my game progress and other data, so I don't know if that would help but I suspect it would.  Maybe when I can jailbreak again and backup my apps on my own I'll be able to try this.  I've gone through most of the suggestions for improving battery life on the iPhone and I'm still consistently losing 16% in 4.5 hours. 

I contacted apple and they referred me to the stupid list of things to do to save battery life. I did all of them and nothing works. After turning off this and that I am wondering why I bought such an expensive phone IF I CAN NOT USE IT!!!!!!!!

Seems like alot of threads out there about this, would be nice if Mods could merge them all!

It does seem like the new iPhone 4S is suffering like its predecessors with battery management and hopefully there will be a patch soon.

With any new devices, we're too eager to get it up and running, little realising that there are so many things running in the background of the device, draining the battery and half expecting it to last for days on end!

Conditioning of the battery is key here, it'll take several (if not many) charges to get the battery at its peak, also very importantly the use of what is running in the background.

On day one I got hardly half a days use out of it, after a 2nd charge and some fine tuning it's improving.  I charged mine pretty much for 5 to 6 hours, left for work at 9am at 100%, finished work at left at 7.30pm at 79%.  Now bearing in mind, I did use my device on my lunch break for 1/2hr using WiFi doing some browsing and a few rounds of good old Infinity Blade.

Here's what I've turned OFF

• SIRI - Great innovative idea, but not for me
• PUSH emails to FETCH hourly, next test is MANUAL
• Notifications, only the essentials, calls and texts, all else OFF.  Not really in need of weather or stocks.
• Sounds, everything on 50%, no keyboard clicks or lock screen sounds.
• Vibrate OFF
• Locations Services ON for KEY applications, such as MAPS.  Not really bothered about Angry Birds knowing my location
• Brightness down to 50%
• Auto Brightness OFF, keep the brightness to one level, the auto up and down is draining additional power.
• iCloud OFF (actually I press delete, now it asks for my Apple ID password again)
• Time Zone Support OFF in Mail, Contacts, Calendars
• Facetime OFF
• iMessenger OFF, have unlimited texts anyways
• Music EQ to OFF
• Spotlight Search to key categories, names, emails, notes, etc
• System Services to ALL OFF (found in Location Services)
• No iTunes WiFi sync
• Ping OFF (disabled APP in Restrictions)
• Date & Time set manually
• Traditional Closing of Apps when no longer needing them.
• Don't Send for Diagnostics & Usage

Seems a bit extreme you might say, however I've turned OFF the non-essentials for me, it's now 10pm and still running at 70%!  I've turned anything location based OFF.

Feel free to tweak it around to meet your needs, some things you need on and let everyone know your outcome.  It'll be interesting to see what people have ON/OFF and what type of battery usages they can get out.

All add to the complaint list, because this is pretty ridiculous. And this is Apple's claim about the 4s' battery performance when advertising the product:

"Two cores in the A5 chip deliver up to two times more power and up to seven times faster graphics.² And you’ll feel the effects. Fast. iPhone 4S is quick and responsive, which makes all the difference when you’re launching apps, browsing the web, gaming, and doing just about everything. And no matter what you’re doing, you can keep on doing it. Because the A5 chip is so power-efficient, iPhone 4S has outstanding battery life. The power-efficient A5 chip and iOS 5 deliver outstanding battery life. So you can keep making calls, checking email, playing video, and browsing the web." -http://www.apple.com/iphone/features/#gallery-performance-battery

Battery life is pretty horrible. Mine drops down from 100% to 92% overnight, waking up 6 hrs later, with no use, everything is turned off except the AT&T network for calls and texts. And of course as many and all have complained here on this discussion board, the battery life continues to drop throughout the course of the day.

Hopefully this complaint has already caught Apple's attention and they're in the process of a fix. This is a similar case with the launch of the iPhone 3G if anyone remembers. Battery life was bad, and fortunately Apple provided a software update that seemed to fix the problem. I'm keeping my fingers crossed that this will be resolved in the same manner.

Just to give me 2 cents on my first smartphone, that i patiently waited for from sprint. Yeah, my battery ***** too 100% battery at 830 this morning to 42% to now 5:26(after doing everything in the forum, that shouldn't need to me done.) I just think Apple needs to realize that it's an issue! Let's hope they don't let us down!

I left mine on standby while I slept and it went from 100% to 80% in 6 hours. There's no way my iPhone 4 was this bad.

So I have traded my iPhone 4 for a yellow screened phone with a battery that doesn't last a whole day. Mine was dead yesterday after 5 hours usage 12 hours standby :(

I am also having terrible battery life with my 4s.  My iPhone 4 with iOS 5 and similar settings had much better battery life.  I am not a heavy user at all, but I'm afraid my phone won't even last a day at this point.  Apple, we need a fix!

We have MUCH less with an the 4s.  I NEVER had to turn off all of the features on my 3g or 4!  What is the purpose of it if we have to disable everything!  I am working from a home a great deal of the time so the WiFi connection is important to me.  And, I would like to have mail notifications!  What a nightmare!  All of the new features and those we had before are now pretty much non-existent!

APPLE:  Are you listening???

also going to add my complaint to the mix. brand new iphone4 battery drains rather quickly when using.  I did try the turning off the time zone setting to see if that fixes the issue as it was mentioned early in the thread.  Hopefully more people come forward and apple takes the complaint seriously.

Yeah my battery is being weird too. i wake up unplug my 4S and after an hour very little use 10 percent of the battery is gone. hope there is a fix soon. I upgraded from a 3G and at the moment my 3G outlasts my 4S

Just a quick note to add to the list to (amiably) pressure Apple.  Yesterday, my iPhone 4s was at ~75% as I left for work; with about two 20-minute surfing sessions (commute) and about a 1/2 hour use during the day (setting up work email, and playing with my new toy) -- the phone was at 4% when I got home!

So, charged it up, it was at 100% when I went to bed, 94% at 6:00 a.m. today... after maybe 2 five-minute sessions of email and 20 minutes of news reading on the train, then a lot of standby, by noon it was at 4% again !!!!!, thankfully I brought my charger to work today.

Since then I've basically turned off everything - Push is off, notifications are at a minimum - and the battery seems to be doing better -- BUT, I shouldn't have to turn off all the features that make this a great phone, just to use it!
