Stock Email Battery Drain

[AspenQn]

Last night my fully charged S6 Edge was taken off the charger and left next to my bed. When I got up 7.5 hrs later I was very surprised to see that approx half my battery was gone and all due to the stock email sync. I have unlimited data and didn't bother changing the sync to longer intervals rather than push. I also usually plug in my phone to charge overnight versus what I did last night.

I have obviously changed the sync interval but wondered if anyone else has experienced this drain. Guess it is finally time to find a new email app!

"I SUFFER NO HARDSHIPS DOING THIS" - this means that i personally am
giving up NOTHING with these tips. i'm not giving up any features.
there are no tradeoffs for me. a tradeoff or a hardship would be to
turn off PUSH email or use AIRPLANE mode during the day etc.

you have to find your own balance and the tips list is a start but you
must come to your own conclusion as to what's important. it's personal
preference but these are not a big deal to me at all as they do not
affect the function or operation of my phone. these tips do not
deteriorate my experience.

Hey guys! I wanted to share a good news! I came across this thread among many others last week while trying to find solution for my severe battery drain caused by Email Sync and Google Services. By the way I am using Samsung Galaxy S6 running Android 5.1.1.

I contacted Samsung via live chat several days ago. They asked me if the phone has been dropped or got in contact with water (if your phone has been dropped or got in contact with water maybe it's the root of your problem--you should get your phone's hardware checked) to which I said no. They then asked me to boot my phone in safe mode and Email Sync (and Google Services) still drain my battery so much! They then suggested me to backup all my data and perform a factory reset. It worked surprisingly well! Now I don't even see Email Sync in my battery usage, and Google Services only uses at maximum 5% with High Accuracy (in Location) selected.

It turns out the culprit was one of my third-party apps. It was Doze battery life saver--some people swear by this app so I think maybe it works with some types of phones but I also saw one user complaining about how Doze's VPN "broke" their phone's GPS, making Email Sync and Google Services drain their battery, even after uninstalling. So I uninstalled that app, backed up everything else, and performed a factory reset, which worked well. Do you guys have any kind of battery saver or do you use some kind of VPN? If you do you might want to try uninstalling them (AND perform a factory reset after). Uninstalling them only might not work! I tried that and I still needed a factory reset cause the app created havoc inside my phone's system. I don't know what it changed but factory reset certainly did the trick of reversing whatever that app did.

So that's it. You guys might want to try doing a factory reset. It doesn't even take that much time. Just back everything up, then Google will download everything for you after your phone turn back on. Cheers! Hope this helps someone.
