[Galaxy S6 General] apsis:
My battery life is impressive with this phone. I almost have 6 hours SOT daily with like 20 hours off the charger. All connections on except location. I did follow a few tips, the problem is they are wide spread all over the s6 forums here, so I try to put them together here.

A few users report that after restoring data in the first setup whether it is samsung or Google, might lead to battery drain. If you do have bad battery life, you should start from scratch and skip restoring options.

Also the data usage disclaimer for both, Google and Samsung in the first setup are said to be battery hogs. You should take care to unchecked those in the first setup.

I had a great battery life from the beginning, but there was always a high amount of android OS and Google play services.

With the updated (side loaded)google play services version they are still at top places, but there is almost no standby drain for me.

Be sure to update to Google play services 7.3.29 via play store if available or side load it.

Do the Samsung push update which is available at the play store. Wasn't an improvement for me, but a few people are reporting reduced drain.

I don't like to cut down my phones functions, but for enabled location service there was always a drain for me on nearly every android phone. So that's one of the few things I will always disable when I don't need it.

Location report is a well known battery drainer ,if you don't need it, be sure to disable it.

If you are rooted (I'm not) there's an big with one of the first TWRP versions not letting the device sleep well. Be sure to update it or go back to stock recovery.

I always used greenify on my rooted phones. When I tried it on my unrooted s6, things started getting worse. Don't know what's wrong, but I removed it and instantly battery life was fine again.

S voice: that's an app I always disable. I prefer to use Google now instead. If you don't need it, you might also want to disable it.

Facebook: the last Facebook versions always were big drainers for me, no matter which phone. Even with its sync, location and chat disabled it just stayed awake and killed my battery. I removed it and started using the website, was a big improvement for me. Give it a try, if you still prefer an app -check out the lite Facebook alternatives on the play store.

WiFi standby: can't really judge about this one, at the moment I'm using : no, always mobile data in standby

Searching for networks: there's only one WiFi network I'm

Connected with that's why I chose: only when WiFi enabled. At least it won't search in standby

Smart network switching: right at the moment I have set it to off.but I couldn't see a change while keeping it awake. Might be an improvement.

Quick connect: I was wondering that with WiFi disabled in standby, WiFi and Bluetooth still were active all the time. When I opened quick connect, I disabled the always visable option. I guess is personal taste, I never used quick connect before, not even sure what it exactly can do.

For file transfers I prefer WiFi direct (superbeam for example).

Of course disable the apps you don't need.

Disable trust agent if you don't need it. (Still have it enabled, but it's said to be a drainer).

Follow the steps, restart your phone, charge it up, unplug it and let it sit with your connections enabled. After a while (few hours would be good). In my opinion everything lower than 1%per hour should be fine. If it's higher, check if your device sleeps well.also check gsam and battery stats,take a look what might drain your battery.

I also find going to application manager and check the running apps to be helpful often. See if there's something running that you haven't used in a while .if so, try to close it and take care if it might happen more often in the next days. (Dropbox was a culprit for me).

I guess automatic brightness works really well for me, try it.

The default email app was a battery hog for be aswell.i closed it (it will reappear from time to time with a slight drain)and switched to Gmail.

If you don't need everything to be synced, be sure to uncheck the unnecessary ones. (I do sync calendar, Gmail ,contacts, Dropbox, onedrive,WhatsApp and have a few apps on push notifications).

Disable VoLTE on us carrier should be a help on battery life, no idea cause I'm not in the US.

Disabling WiFi if you don't need it. I have no idea about this one, a lot of people are reporting this. I for myself keep it enabled for the whole day, even when I'm not near my WiFi network. Can't see a hit here in battery life.

I hope a few of you guys with those horrible drains might fix a bit of it with any of these tips

Below are pics of my actual battery cycle, not even down to 50% with 3+ hours SOT (automatic brightness, 4g,WiFi, sync enabled the whole day.)I Wasn't in reach of my WiFi network for several hours. I haven't used any battery saver.

Usage: browsing, reading on tapatalk, hanging around in the play store,texting on WhatsApp, watching a few videos on YouTube, taking a lot of shots with the camera -playing around with its different modes. Some short callings .
