Okay, so I was wrong. You definitely shouldn't have to turn off push notifications and sync options because in my iPhone 4 running iOS5, EVERYTHING including wifi can be on, and i won't loose more than 2-3% all night, if that.

Update - I let it die completely until it shut off yesterday, let it charge completely, left it plugged in for a while. I left it unplugged last night when I went to bed, without having really used it very much.

This is what my usage says now..

I'm at 35% battery, and usage is 3 hours 33 minutes, 15 hours standby.

Meanwhile, a friend with iPhone 4 says his is at 78% and he has usage of 2 hours 36 minutes...

I really hope this get fixed in a software update soon.....

So between the time you went to sleep and woke up it was used for 3.5 hours, without you touching the phone? Sounds like something is active in the background.
 
Yea, I let mine get to 1% last night, let it charge until today to 100%... Unplugged it and didn't even turn the screen on.

After 1.5 hours it was at 95%.

Just sitting there with the screen off.

iCloud is disabled, Bluetooth is off, I have one push account, all background apps were closed and find my friends isn't even installed.

I can only imagine if I was using it.
 
I think it's prob a software issue. All through the betas it was up and down. I stuck with beta 6 because battery was excellent. When it expired and I had to move to 7 it was much worse, much like the GM.

Also, worth turning off a few things under Settings, location services, system services, I doubt you really need them all.

Just to add I have a 4.
 
This might not have anything to do with your issues, but my phone dropped 10% while it was charging while using Siri. Siri is a battery hog.

No no I meant, I used it for maybe an hour, hour and a half last night.. And used ths morning on an hour drive to text, and dictate mabe 4 messages on Siri and ask for weather in 3 spots.. I've definitely used the 3.5 hours.. But the fact that the battery is already at 35%.. That's way too low.

My iPhone 4 would average 6 hours each day of use.. iPhone 4s definitely drops 1% every minute the screen is on or more
 
Took my phone off my charger an hour and a half ago. Only thing it's done so far is an alarm went off. Still at 100%.
 
You know, there would be a lot less complaints about Battery Drain if users would not use the Battery Percentage setting.

Out of sight, out of mind.

I'm just saying. XD
 
I'm currently at 30%
Usage : 5 Hours 45 Minutes
Standby: 17 Hours 37 Minutes

I lost about ~5% while I slept, and about 80% of my usage has been on wifi.

Also, to all the people asking why we don't charge our phones overnight: When I get home, I plug in my phone. Well before I'm ready to go to sleep (1~2am), it's already fully charged. There's no point in me leaving it charging at 100% for over 8 hours. Not only is it probably bad for the battery, it's a waste of electricity.

Apple might have been smart to not offer a % feature. It only encourages the already prevalent OCD tendencies we see surrounding the iPhone. This being said it appears there's an actual battery issue some are having.
 
4S battery lasting about 2 1/2 days...very light usage (1 HR calling, 25 min surfing web/3G). Wifi on for half of time, Bluetooth/location services/diagnostic forwarding/iCloud/wireless sync ALL OFF.


I remember my 4 being MUCH MUCH better.

*That said, its still a crazy improvement over the HTC Inspire ive been using for the past 3 months.

PS: Siri is cool, but am I the only one who's not blown away by its "speed"? My iPhone 4 seemed barely slower. Cheers Ya'll
 
Charged mine to 100% overnight.

Been awake and using the phone off and on for the past 3.5hrs....phone is at 96% :)

I get the "saving electricity argument" but,

OMG!!!

NOT THIS AGAIN!!!

You will never, ever over charge an iPhone's battery. The Power Management within the iPhone knows when to charge and when to stop charging.

PLEASE STOP PASSING ON MISSINFORMATION!!!
 
Set up as a new phone, no problems with my battery :)

Bluetooth/Location services off. I can't be bothered listing all my settings but I'm pleased with the battery life :)

No kidding plus they make those cases with the battery built into the case so your phone is always charged (well until the case battery runs out) If that was bad for the phone htey would not be making them

It is actually better to top off when ever you can. I don't even bother doing a doing a full drain these days.
 
Went to sleep with 35... woke up at 35...granted i only slept three hours though it doesnt seem that bad of a loss..i don't seem to be experiencing bad battery.
Anything is better than my T-Bolt that went from 56 to 15 in 2 hours of sitting in a locker

What is your usage in those 3.5 hours? 30 min? More?


I let mine charge to 100% last night. Went to bed and woke up 6 hours later with 99% which is good...but right when i start to use it lightly...check mail one use an app for 5 min and send a few txts..it drops 1% every 2-3 min still...hmmmm


If i set up as new phone i lose everything correct? ugh...
 
Mine is fine ... drained 8% overnight (1AM-10AM), I have iCloud, Siri, open.

If anything, BLAME it on other apps that aren't optimized for iOS 5.
 
I had this issue with my 4s as well. What fixed it for me was the following:

let is discharge to 0% last night (shut down by itself) and charged to 100%.

THis morning i did a full icloud backup and restore.

that seems to have solved my very quick battery draining (1% every 3 min or so lol).

I really suspect the backup & restore solved the issue here, if anything you guys should try that and see if it helps.

edit: would liek to add that i initially did a brand new phoen set up when i first got the phone

edit2: i had also tried readding my exchange accounts last night but that didn't solve the issue.. what i tried specifically: 1) delete exchange accounts, go through mail contacts and calendar to flush out any pending queues, reboot, readd exchange accounts w/ push. Also reset network settings prior to doign this (followed by reboot)

Lost about 20% overnight while sleeping. Left it unplugged as a test, I usually charge my phone overnight. Went to sleep at 100%, and 8.5h later, it was at 79%. Going to try setting up the phone as new today.

Let us know if it changes it...i may do thise as well but i don't want to add all new contacts ect...
 
coming from an android which completely destroyed my battery even in standby.. im content with the batt on the iphone 4s although i guess it could be better for usage.


anyways my issue is that my phone gets warm quickly.... anyone else have this? my iphone 4 never got warm....

Note how I said probably. There's just no point in leaving charged overnight unless you absolutely have to.

Also, people are in here complaining about ridiculous battery drain, yet mos people in here are just telling them to charge overnight? That's not a solution to the actual problem (the battery drain).

The only advice I can offer is to turn off location-based reminders. If you still get crazy battery drain, try turning off push notifications. If that stops the drain, you can enable push for each application until you figure out what causing it.

It sucks to here that people are losing over 50% of their battery overnight. I lost only ~5%
