Batterygate??

My god, that's an amazing result. It's twice my usage amount!
Are you running the latest beta?

@Reach9-Nope still on iOS 5.0 strangely, I was quite shocked myself, the GPS usage alone should have killed a lot of it.

@Sulten-I charge it overnight. When I go to sleep, I will leave it to charge. For some reason, I can't manage to sleep more than 5-6 hrs at a time without waking up. So whenever I wake up during those intervals, I usually take it off at 100%. I'll usually wake up in the next hour or two for work and it still reads 100%. I work in an office cubicle every day, so I have ample time to use it.

@aberrero-You don't have to believe me, I just posted so others could see.

@Ashin-Could be, but this was my very first time "hammering" the 4S. I felt it getting warm and that hasn't happened since i restored and deleted iCloud off of it.

I had battery problems out of the box like most of you, and probably still do, but I eventually restored my phone as a new phone and skip setting up iCloud. That has helped me tremendously and is probably the reason it can now go overnight without losing battery.
 
So, this is it- 3G internet only as a usage:

Good or bad?
 
Ever since i upgraded to ios 5 battery efficiency under normal usage has been, well... amazing. But there's more to the story. I suspect the culprit for most of the battery problems i hear about in this forum are network coverage and carrier settings. The point is, battery has been mediocre in the first days on ios 5, than a message popped on to my screen, telling me that "new carrier settings" are available for my device. Updated, rebooted my phone, and battery has been great ever since. For the record, i have a black iphone 4, ios 5 on it, icloud disabled except push mail, plus an aditional two mail accounts fetching every 15 minutes. I have facebook and twitter push notifications enabled, screen brightness set at 50%, other than that is't a normal setup.
I posted a pic bellow. I took it off charger at aprox 6 am, went to sleep, woke up to find two text messages, a missed call and one facebook notification. Sent one text, checked facebook once and had an outgoing call of about 15 minutes. Battery procentage: 99%.

Anybody have push e-mail on...how much difference are you seeing in battery life? on my 4 I didn't see much of a difference to be honest.
 
my battery drop 10% overnight for a 8 hrs sleep. does this consider normal? :confused: wifi on push on.

Mine has bluetooth on (No connection), Wi-Fi on (Connected to house network), checks 4 email addresses every 30 minutes and Push off and I lose 2% for an 8hr sleep. I also have full signal strength at home and I know low signal really saps the phones battery
 
When I got my new iPhone 4S, I thought the battery was terrible. It drained away in next to no time. Since having it for a few days and going through a few charge cycles however, the battery life now appears to be far superior to my old iPhone 4.
 
about average 25 email and message total when i woke up .... ;)

well i normally lose 3-4 % overnight and when i left push off overnight i had about 10 ish e-mails which made me lose 6% over that time so I would say e-mail may have something to do with it if you get alot of e-mails.

try switching push off at night.

Happy for you that you've got a phone that "works", a few questions though that could help clarify if the same will happen to me or not:)

During the first cycle when you thought your battery was "bad" how long did it stay alive at 1%? Would you say the time it took to die from empty battery is the same now as before charge cycles only it went to 1% faster and the was alive for a long time or is it in total better now?

For those following my status this is my latest report after having 5.0.1 v2 installed and cellular info updated, emptied battery once and did a full recharge with the phone in the charger for about 8hrs in one go:

Features:
Bluetooth off
notifications a few on, none except phone and message actually used
push on, but nothing was pushed
WiFi, testet both on and off, no difference
3G on, but not used, was on WiFi when surfing.
locations, about 10 apps on, maybe one used for a short time. iAds, Time Zone and Traffic off.


Usage: 36 minutes
Standby 4hrs
Battery: 85%

Usage was surfing on wifi about 20mins and rest was checking settings,mail etc.
 
Couldn't take the battery drain any longer so I took mine to the Apple Store. After scanning the phone, they told me that I was getting 4 hours of talk and 12 hours of standby. So they replaced my phone and said a software fix should be coming out in a few weeks.

They also said that not all phones have the battery problem. They recommended I first restore with iCloud and if I still had battery problems to restore using iTunes. If that didn't work to setup as a new phone as a last resort.
 
Posted the stats above right before going to bed, these are my stats when waking up:

Usage 1hr
Standby 16,5 hrs

Battery: 38%

Got 3 sms during that period and sent one, that's it for usage.
 
With the latest beta on iPhone 4S, I managed to get almost 9 hours of usage and 24h standby. I used my phone for mail, surfing, texting, apps, camera, Musicplayer, Harmony Link(TV-remote) and some Spotify-streaming. My daily usage.

Wifi, iCloud, bluetooth and mail(push) are all turned on.
Turned off some of the Location Services as iAd, timezone and diagnostics.

A lot better battery for me with the latest beta. Now the battery is on par what I was used with by my old iPhone 4.
 
Kept quiet checking this thread to see how the story develops, but I feel I need to chip in few things now..

- In my experience, what's causing battery drain, and high usage over night, where there was actually no usage are rouge network connections, open sockets that attempt to send data but for whatever reason, either don't understand the answer or the process controlling them is hanged. These connections, when in buggy, indefinite "usage" mode are easy to spot in any netstat utility as they will not switch over from 3G/UMTS to wifi when wifi is enabled. Everything else active will jump over, but one, rouge connection will stay behind with open socket time listed as 20+ minutes to several hours.

- The solution to the problem is the same every time, and in a way - just about every solution posted on this forum to date does the same, if via somewhat long way around method. You need to kill all network connections and get the service/daemon causing this drain to restart polling/submitting/whatever-it-is-it's-doing. A simple hard reset/reboot will do. You can go the long way around and do full OS reinstall, restore etc etc, reset network settings, disable all data, etc - the "cure" is the same - reset all network connections, all services/daemons regain sanity and drain is gone. You can also try and wait it out - disconnect all network connections - wifi/cellular data for long enough and every active thing trying to open net socket will eventually reset itself and work properly again. Trouble of course is - sooner or later you'll open something and that something will hang and start draining again.

On my phone reboot before I go to bet is a guaranteed solution to finding that the phone had a peaceful stand by and very little "Usage" counter stat in the morning and battery drain is perhaps 1-2% over 6 hours.

I can't tell you which of the services/daemons is causing this. I don't know. Maybe all of them are equally prone to hanging, maybe it's the watchdog process looking after them, but I can tell you this much - in my experience the "hanged" connection causing drain is most likely to happen when you travel between cellular masts - if I take my phone off the charger and reboot before jumping in my car and travelling 50 miles on the motorway, after I reach the other end of my journey, the "Usage" counter is almost as high as "Stand By" figure. If I keep it on the charger all the way, then reboot before entering my office, after 8 hours of just being in one room, the "usage" is very low and so is the battery drain. Just that this time around, the phone doesn't need to keep searching for data signal. Some of you will say it is logical that a phone moving quickly between masts shows "Usage" all the time, but consider this - iphone 4 with 4.3* soft doesn't do it at all. It travels without Usage constantly growing during 100% of the journey/

There is also additional piece of the puzzle - in UK, we have two cellular providers Orange and T-Mobile merging into one giant provider at the moment, and their "merged" masts and infrastructure is available to clients of both providers via "internal roaming". At home the mast of my primary network - T-Mobile - is about 700 yards away in straight line and mast of the "merged" co-provider - Orange. Sometimes, only sometimes, if I switch networks manually, from T-Mobile to Orange, I get fantastic 5 bar signal and fast data connection, then 3-5 minutes later 5 bars go down to 2, then 0 and I get popup with "Network Lost - Your selected mobile network is no longer available" and then it switches back to T-Mobile masts. It is almost as if there was some sort service running in the background, checking sanity of data networks at all times, and because it becomes hanged when masts/providers-while-roaming are switched, it tells the phone to start desperately searching for alternative masts, and it looks as if my phone decides to drop the nearest mast and tries to connect to masts all over town instead until whatever tries to use stack on cellular data times out. If I reboot, then manually switch to Orange, the phone happily stays on Orange for entire weekend, without issues.

All of it, complete speculation, but you are welcome to test it on your own phones. Download netstat and observe it yourself.

I addition, there are couple of "oddities". On my phone, the connection that hangs in "open socket" mode for minutes and hours no end is always to bz.push.apple.com. Push services are disabled on my phone, I can only presume this is some sort of generic name used by all services/daemons on iphone. Why that connection has to be there at all times, I have no idea, but it is there, and it becomes hanged, you'll notice socket open time growing and as I said earlier - when it's hanged it won't switch over to wifi when you enable it and stay on cellular data.

When that connection is "hanged" in open mode and you have any kind of data monitor, you'll notice it's slowly leaking kb of data over night, even with every single program manually closed via double tap of home button.

You'll notice even with all applications closed and netstat open there is unexplained data polling going on where the phone constantly opens short bursts of connections to aggregator servers at apple, amazonaws and teliacarrier (which is odd in UK, where we have no telia) every few minutes.

When you experience battery drain, and you use any kind of task monitor, you'll notice that some applications never properly close. Once the drain starts on my phone, for example, the MobileMail process stays on the process list even if I manually close it by double tapping home button and killing it with (-) sign. It's not there after hard reset of the phone. That looks to me like any of the services might be equally prone to being kept open by net connections and sockets not exiting and just runs forever in the background.

Take it away forum - check netstats and monitors on your phones and see if we are onto something there...
