S3 battery dying overnight

Hey guys,

I realize there have been a few posts about this in the past but I still have yet to find an answer so...here we go:

I bought my S3 about 2 weeks ago and noticed that the battery wasn't keeping it's charge overnight. During the day, it would be fine but at night it would die.

In order to try and fight this, here are the modifications I have made:
- Brightness on lowest setting
- Mobile data is always off
- Wifi is off
- Deleted Facebook since I thought this may be the problem
- Disabled most Samsung apps
- Downloaded Gsam
- Downloaded Wakelock detector

It seemed to have helped my battery significantly during the day, the battery itself used about 20% in a 12 hour span. However, when I woke up this morning it died again (that's 80% overnight).

Gsam tells me that the biggest problem is coming from "Exchange services" and Kernel (Android OS).

As for wakelock, it states that Calendar sync woke my phone up 444times last night.

Any idea what I can do (except route) to try and make it normal.

I think it's also a good idea to let you know that my gf bought the same phone on the same day and she always has wifi on and her battery lasts about 2 days.

Then your sync off at night, nfc, gps, set your timeout really low, turn off wifi and mobile data and Bluetooth. I do those things at night and I don't drain my battery a lot, you can also try Easy Battery Saver in the Playstore.

Sounds like the big problem is coming from syncing with Exchange. 444 times is pretty much syncing every minute for 8 hours (okay, 7.4, but let's not split hairs over 35 minutes ;) )

What it looks like is that as soon as the phone goes to sleep (1 minute timeout) sync wakes it up and this goes on all night. Yeah, that'll suck the life out of your battery.

You can change the sync with exchange to every 10 or 15 minutes (I sync most accounts only once an hour because most important messages/mail is pushed anyway) or you can leave the phone plugged in over night.
 
Thx but what I'm also wondering is...

...how do I change the sync in "exchange services" specifically?

Is it done within my e-mail application or...?

Any exchange accounts will sync through your email app. Open your email app and press menu>settings and you should see a list of your IMAP (exchange) and POP3 email accounts. If you only have one account setup it might go right into settings. In any case tap on the account and scroll down and you should see a setting for frequency. You can change it to sync every 1/2 hour and save considerable battery. I do believe the current IMAP protocols will push email notifications to your phone so you don't really need to sync that often if you don't want to.

Would the "frequency" be under sync schedule?

My "Period to sinc Email has always been at 3 days and the peak schedule was set to push.

I think that means that it will only sync email for 3 days so it doesn't bog down trying to sync email from months (or years) ago. Unfortunately I don't run an exchange server at work so we sync a little differently. Given the numbers it certainly sounds like you've got something sync'ing with exchange every minute at night. Maybe if you have a chat with your IT dept. and see if they have some sort of after-hours policy in effect that would change your sync behavior at night. Just guessing there.
 
If it is the syncing I use a small Widget called,"EZ Screen Off" and one of it's two widgets you can use also turns of syncing.Try that at night and see if it helps?
 
I can try that but would it be any different then putting sync off?

I've pretty much never had my sync on and it still uses exchange...I'm at a loss right now.

I have noticed that resetting the phone seems to improve the phone for about 10 hours and then the battery just crashes once the exchange services gets going...
 
I think it would be the same but it's worth a shot.Another thing that might help.I use Deep Sleep Battery Saver(DS Battery Saver) and you can set in it's profile/options a,"Night" regime.I have mine set to shut almost everything off between midnight and 8 am.
I have to re-enable some things in the morning like packet data etc but i can live with that.

I find this very interesting. If it's a wakelock issue, it would present itself during the day as well. Getting that much battery life during the day when the phone is more likely to be used, and then having it use so much overnight doesn't seem right. Any ideas why this issue isn't present during the day? What's different at night?

I don't turn anything off, ever, and I get great battery life. The solution for you isn't to live this way. Leaving Wi-Fi and mobile data on as well as Bluetooth doesn't really suck much juice. My screen is usually my number one power draw as is chrome.

I hope you get this figured out. Nobody should have to turn those things off and on as needed. I used to do this with my other phones, but then realized that I wasn't really enjoying my phone having to pay the juice game.
 
Sometimes even new devices can have defective batteries. You should try contacting samsung about it. The reason is that all these batteries are lithium ion which basically means that they only get a certain amount of charges before they stop holding a charge for a long time. Laptop batteries are the same way. Just try contacting them and they will send you a new battery.
