Apple Continuing to Investigate iOS 5 Battery Issues

with new update it's even worse. I did get slight decrease after updating to iOS 5 but now my phone can't last 1 day!!! I completely drained battery yesterday after the update, left it charging all night and now it's 8PM and have 5% left. I used to charge my phone (iOS 4) every 2-3 days. WTF is going on??? Seems like some dodgy code is running in the background. Apple employ proper QA team!
 
I decided when I got my new iPhone 4S that I was going to start over from scratch. So I didn't restore from my iPhone 4 backup. I haven't noticed any significant battery problems.

Current Usage:
Usage: 1hr, 12m
Stanby: 6hr, 1m
Battery at 80% without being plugged in.
 
I had the issue, but this fixed it.

My iPhone 4 was running hot and the battery was draining in half a day while idle right after the iOS 5 update. The solution I found on the Apple forums was to delete my mail accounts, reset my network settings under Settings -> General -> Reset, and then set up may mail accounts again. I had no issues after that.
 
So the 3gs still the less worst option, 4 with antenna issue, 4s with battery problems.
Bad engineering, bad engineering apple.

troll, who said that 4S has battery issues? if you know what you're talking about you would know it's related to iOS 5 not iPhone 4S

The thing is users shouldn't have to jump through so many hoops to get things working the way they were intended. That's how other people do it, but generally not how Apple does it.

My 3GS had no battery problems on iOS 5. Can't say the same about my 4S, even on 5.0.1.
 
iOS 5 & iPhone 4S dire in standby

My old iPhone 4 could be left overnight on standby and use only 6% power

My new iPhone 4S with iOS 5(.0.1) eats around 30% overnight

I hope apple fix this issue ASAP otherwise I'll have yet another iPhone 4S replaced (I had to get it replaced on day 2 owing to it crashing/panicing every few hours)

I have disabled all the Location services bits others have recommended, and the damn thing still eats 10% per hour

If Apple say this is affecting a "Small number" of users, they are probably only meaning the vocal ones , I suspect there are a large number of iPhone 4S users with the issues (and some probably dont realise the battery is an issue having come from phones that get less battery life than the iPhone 4S is capable of)

I dunno, is that acceptable? As a practical matter it means you're getting about 4 hours use before you need to recharge. I get about the same and I'm not happy with it.
 
It seems to last longer with 5.0.1 but even if i use it a lot for work and fun, iPhone can be charged overtime you want, and i always charge it when i got home, never worried about battery. I think there are still bug left, but some people are paranoid and other just doesn't know how a smartphone works. I'm not saying everyone is one of these 2 categories but believe me, every issue seems sooooooo big on internet forums. Like everyone is getting this problem.

I see people saying that a 10% battery loss every hour or so in standby is "what you should get." No, that is false, and saying that is just trying to avoid the issue at hand.

I'm running an iPhone 4 (CDMA) and have not had any battery issues with any build of iOS 5 (including the beta version). Losing 10% in STANDBY is inexcusable, unless you're in a low/no coverage area.

This is clearly an issue, and not one that can be waved away by some forum members because they're not experiencing it. It is either an issue with iOS 5, caused by bugs in location services, the A5 chip, or the battery (remember, the battery capacity on the iPhone 4S only increased by 10mAh, an insignificant power boost).

What i was speaking about. IT IS WRONG, like a modern notebook you should charge eveytime you can or at least every night because it is better for you and better for your battery. If you completely discharge your battery, it will last less in years and you will have often low battery. charge it every night, lithium battery doesn't need to be drained off, it is the opposite. Every smarthphone should last a medium usage day not more.

Agree. I think it is a matter of starting fresh vs restoring.

I did the same, and did not experience any significant battery issues. I am using this phone a lot and typically get 6 - 10 hours of use (Phone, text, web, music, Pandora), and I am on Sprint, which supposedly has the lowest power towers and the lowest battery life since the phone has to work harder.

That is what it's supposed to lose. At that rate, you'd get at least 10 hours of battery life when it's being used, and even more if it's on standby.

What? He said he loses 5%~10% an hour on standby. That means, on average, his battery, on standby would go from full to empty in ~13 hours. How is that what it's "supposed" to lose? Apple claims up to 200 hours of standby time. He gets 13 :cool:

10% is wayyy to high to be losing on standby, unless he is in a poor signal area. I have 4~5 bars on Sprint, and my 4S has NEVER lost more than 5% while I sleep (6~8hrs).
 
darn android and all its bugs... Oh wait :rolleyes:

guess "just works" only applies to OSX and macs as always... Oh well, the iOS user base is like the PC people (don't know any better anyway) just another example of the dumbing down of apple by iOS

I think that is what I will do this weekend. After updating to 5.01, I'm still having problems like anyone else here. My battery was improved but never like in iOS 4.

I'm gonna wipe my 4S and restore without my backup and see if that will improve.
 
Didn't help my issues. I still have to turn off 98% of items in Location Services or I experience heavy battery drain, even in stand-by.

Mine is the exact same. possibly worse with the update. I have everything turned off except one thing in location services.

Did you try to full discharge it and then full recharge it to callibrate the battery ?

I have the following:

Usage: 9 hours, 29 minutes
Standby: 1 day, 7 hours
battery at 34% without being plugged in
 
Based on the Apple provided numbers, here's what you 4S owners should (roughly) be seeing for battery drain under ideal conditions:

Talk time - 8 hours on 3G
Loss per hour: 12.5%
Loss in 30 minutes: 6%
Loss per minute: 0.2%

Standby time - 200 hours
Loss per hour: 0.5%

Internet use - up to 6 hours on 3G
Loss per hour: 17%
Loss in 30 minutes: 8%
Loss per minute: 0.3%

Internet use - up to 9 hours on WiFi
Loss per hour: 11%
Loss in 30 minutes: 5%
Loss per minute: 0.2%

Video playback - up to 10 hours
Loss per hour: 10%
Loss in 30 minutes: 5%
Loss per minute: 0.2%

Audio playback - up to 40 hours
Loss per hour: 2.5%
Loss in 30 minutes: 1.2%
Loss per minute: 0.04%

(numbers rounded)

Let me followup with the standby time number......I for example on my iPhone 4 on 5.0.1 charged to 100% last night before bed. Woke up this morning still at 100%. So standby should generally be a slow drain, depending of course on what you have running.

i installed the update last night, put it on the charger over night and the battery would only charge to 94%!!!! im going to totally drain it and charge fully see what happends...

this is apple without steve!!! :mad:
 
Could be related to the whole raise-to-speak feature, what with the accelerometer and infra-red seemingly always on.
