[Q] Battery Drain Issue

[Fluffywings]

I am trying to troubleshoot my battery drain issue so I have been inserting a fully charged battery into my Note 2 just before bed.

Stock 4.1.2 ROM
Rooted

Night 1
Before bed: 100% battery, airplane mode
Wake up 7.5 hours later: 100% battery life

Night 2
Before bed: 100% battery, WiFi connected, background sync enabled
Wake up 7.6 hours later: 54% battery life

I have Greenify and BetterBatteryStats and still can't figure out what is sucking down the power.

Sync Interval:
Twitter: 4 hour
Facebook: 30 min
Touchdown HD: Push (exchange)
Reddit News: 12 hours

Any help would be appreciated!

I think you really have nearly answered your own question - it's the syncing that's killing your battery. FB is notoriously bad at draining a battery all on its own and the others may be bad too. The dead giveaway is the phone isn't deep sleeping anymore with sync on. Keep up your experiments but freeze each app/process in turn to see how bad each one is and you'll find out. No need to leave it over night - an hour or two should be plenty to find out. In fact, if you have your phone set for max battery life, it should go into deep sleep within minutes of locking it. Personally I only sync manually and that's including email - but I'm not too plugged in so I don't mind checking a couple times a day manually. It does mean killer battery life though! Really any process that is constantly waking up your phone will do the same thing as fb - Google Now with location history on is another bad one.

I use fb and I get no battery drain from it

Still unsure about which app is the main culprit. Facebook seems like it could be the biggest problem. Attached is my dump from BBS (BetterBatteryStats) I tried the same thing as the night before except I did the following

Facebook Sync: Never
Twitter Sync: Never
Touchdown HD: Push (exchange)
Reddit News: 12 hours

Night 3:
100% battery before bed, background sync enabled.
52% Battery by wake up.

NOTE: 10076 (Wifi) (com.android.vending.Google Play Store): 86.0 MBytes 95.3% was my apps updating just after boot.After all apps were done updating, I put the phone to sleep until morning.

Things I am going trying.

Freeze Samsung Push
Freeze ChatOn
Greenify Facebook

You need to understand that virtually any app that has the ability to poll your phone and push updates to it automatically without you visibly seeing it is going to drain your battery. This includes:

1. GPS
2. Having your data on in general (networks push packets to each other to stay within protocols regardless)
3. Google Accounts (syncs your calender, contacts, people, etc.)
4. Google Now
5. Mail

etc, etc.

I know this is a little off subject but will face book still drain Battery even if you have location off and sync off?

Facebook Messenger was an issue. It kept waking up my device. I have been doing some testing though and have had almost no luck until tonight.

I disabled WiFi before bed with 100% battery. 7 hours later, 91% battery.

I need to find which apps are using WiFi so heavily.

Go grab greenify from play store

I have been using Greenify the whole time. Currently, it looks like when on WiFi apps are going crazy with connecting and waking up the phone. On Mobile, I got much better battery life.

Try backing up all ur data on internal and SD card.. Then do a complete fresh install.

Yes. I have the same experience. When WiFi is on, the battery life is much worse.

Ok Wi-Fi being on won't kill your battery. Maybe you need to set your to, keep Wi-Fi on during sleep= NEVER. That'll help your battey life some what..
