Same problem!!! My iPhone 3G!!!uses less battery!

Wifi/bt off, one push email, notifications on.
1day standby, 1:45h usage ...... 55% remaining!!!

Plus!! I have the brightness on not even 2 out of 10!!

T

My 3G is almost the same,

Developers try to increase the speed of the cell phones but I think the only thing people need is a loooong battery life.

I want to use my phone during the day, without thinking "if I am going to be out of battery before going home"...

I am using the car adaptor, it helps a bit but not enough.
 
Overnight I only lose about 4% on my 4S, with WiFi and 3G on, Push Mail on for 2 accounts, Bluetooth off, Auto Brightness. Nothing open in the multitasking tray. I think the 4S has amazing battery life.
 
My 4S battery is horrible...

I did make a backup of the 3G it replaced, and restored it to the 4S... so tomorrow I will try wiping it clean.

Last night I went to sleep and the battery was at 38% and when I awoke not 6 hours later it was completely discharged / powered off.

I used the AC power to charge it back up to 100%, and I even left it for another hour after I saw that it was supposedly at 100%. I took the phone outside, and started my initial tests with the camera, and shot a 10 minute video.

I snapped 50 pictures, and took the 10 minute video and the battery was at 75%... I thought that seemed ridiculous.

After a few hours went by with the phone sitting on my desk, doing NOTHING I checked it again and it was in the 50-60% range (don't recall exactly) and so I cranked the brightness to 100% and played an episode of southpark I had downloaded over, and over, until the battery hit the 10% warning.

I stopped all video, and put the phone down for about 30 minutes while I finished doing some stuff around the house, and when I picked up the phone to plug it in it was at 3%!

Once connected I decided I would disable every single thing possible in the phone... the only thing on is Cellular Data and WiFi. Granted there are some new features in iOS 5.0 but otherwise I've had a 3G for the last 3+ years so I'm pretty familiar with all the tricks to squeeze the battery for all it's got.

I took screenshots to track what happened from there...

7:04PM - Battery at 3%

10:05PM - Battery at 100% (at least 45+ minutes to an hour after it said 100%, I kept checking it until it got up to 100% and then waited a good while longer)

12:06AM - Battery at 82% and I haven't even touched it.

12:29AM - I just checked it again, and it's at 72%... still haven't even touched it but now that I picked it up the phone is warm... something is most definitely running in the background and KILLING the battery.

----------

When I double tap the Home button, I get the list of App's but is this:

1 - The list of all App's I have recently opened?

2 - The list of App's that are still running in the background?

There are a TON of things on that list, it must be #1 right?
 
I've noticed that the battery drains faster on the iPhone 4S than the iPhone 4 running iOS 5 as well. I start with 100% at 10AM after taking it off the charger and then after moderate usage (emails, twitter, facebook, tapatalk, iMessage), I'm down to 15% at 7PM. Normally on the iPhone for under similar scenarios, I would at least have 35-40% battery life left. I have to start using my Mophie Juicepack more often now!
 
I set my phone up as new rather than restoring from backup which i didnt for me 3gs and 4 so it can't be that that's the issue. Tempted to call apple but it's so early in the product lifecycle they probably won't acknowledge a problem.
 
Ok, my phone was 100% at 12 pm. Over the next 12 hours I talked 40 minutes on the phone, 30 minutes wifi web surfing, and about 2 hours angry birds. At 8 pm it was at 69%. I charged it at 9PM until 10:30PM and it was back at 100%. I ran it down to 88% and went to bed at 11:30PM. Woke up 7:30AM it was at 30%. WTH is that about?

So it drains slower when I use it then when it just sits there?

That's what I've noticed.
 
I don't know what I'm doing right. My battery is doing great (I think anyway). I haven't been using my 4s too much since I got it on Friday. Set up my email,find my friends, find my iphone, set up Twitter and push notifications for my emails & twitter and have used Siri to set up reminders and alarms.When I received it, I hooked it up to my Mac to activate it and sync it with my iTunes. That's the only charge it had gotten until last night.
I took it off the charger when I went to bed last night (at 11pm it was at 100%) to see what the % would be when I got up this morning at 6am. After the alarm went off on the 4s this morning (6am), my % was at 98%.
As of right now, 8:06 am, I've used Siri to set 3 reminders, checked email, twitter & weather, I'm at 97%.

Not sure if it matters or not, but I've seen people mention it in other threads, I do not have the Facebook app.
Also under diagnostics, I have "don't send" and for Siri, I have the raise to speak turned off.

My battery went from 100 to 98 over night.
 
For those with issues - have you turned off iCloud backup and Wifi iTunes sync? Have you left your main PC with iTunes on? Do you have any reminders set - reminders using proximity settings will keep GPS turned on until it has reached the notification location and you have deleted the reminder. This will eat up battery fast - check you don't have the location arrow icon in the task bar.
 
From another thread. iOS 5 has a lot of gos services enabled by default. Mainly the time zone one that will be chewing up battery. Try disabling that and things should return to normal

Response from the batterygate thread below.

I've noticed since iOS5 that my GPS is always enabled. Looking in the settings, it appears the "automatically set time zone based on location" option was on, and constantly using the GPS!

After turning that option off in the advanced settings everything is back to normal

Same issue here. Plug in overnight. Have 100$ when I unplug at 7am. By 2PM, its at 14%. I had the same app's running on my iPhone4 and could go to 11PM with 40-60% battery left. I had the same setup running on iPhone4 with iOS5 up until Friday and had no battery issues. The only new function I didn't have was Siri.
I did notice on the Notifications screen that one of my Exchange calendar reminders was flickering - the text and green dot next to it! Is everyone who is having an issue using Exchange sync?
Perhaps those posting to say how good their battery life is can give input to what is running on their device so we can maybe figure out what is causing the battery drain.
 
wow really!!

Insane. But listen to this! I went to sleep at half 1AM with the phone @ 70%. Wifi on, 3g on (its always on), bluetooth off, push email on.

Woke up at 730 and the phone was DEAD. I charged it up to 30% asap, then fell back asleep from 8-9. when I woke up it was still 30%.

Very confused!


Yeah I had a full charge last night, PUT MY PHONE ON AIRPLANE and when I woke up this morning, DEAD!!!

Are we possibly at the point where this is a faulty batch of iphones?? I did a test with a co-workers iphone 4 upgraded to ios5. Both charged at 100%, both had all apps turned off, most notifications and locations settings turned off on mine, not hers and let sit idle for 1 hour. Hers was at 99% and mine was at 100%. (good right??) She grabbed hers back started texting, I took mine and checked email and one hour later hers is at 97% and mine is at 89%!!! I have had mine for a week with multiple dead batteries and recycle charges or whatever..

I love the iphone and iphone4s, but I am giving mine a few more days and then taking it back for an iphone 4. IMHO a single core processor with a charged battery is a lot faster than a dual core processor with a dead battery.
 
I went to bed last night after charging my iPhone to 100%, took it off charge, then woke up with it still being at 100%

That's how my iphone4 was, maybe a percent or two. but 100% drained while on airplane mode is a bit extreme.
