Restore the app to its factory state basically. 1) uninstall all Samsung push service updates. And don't get me wrong, it didn't go from bad to worse, but rather excellent to good.Īnyways, there is four things that helped in my case. I've been watching the behaviour of my phone and I have found a few things that can help bring the battery life back to its excellence from before the update. From this article you can link off to help pages, but if you're reading XDA, then you're likely already aware of everything in it.įingers crossed that if enough people complain now, a bug fix to your problem will arrive sooner than later.Īnd you can factory reset - just Google that, lots of help around to walk you through it if you go that route. You can try power saving mode, but on the S7, power saving mode stops some apps from working properly, to save power.
#Samsung s7 battery drain android
My Android System is using only 10% of the battery right now.
That drain is not happening for me right now on the S7. On my S4 occasionally apps were sucking the life out the battery, dropping it 30% in 20 minutes of no use. I know 2 hours isn't long, but with battery drain, it's long enough to notice if it's happening. It was at 80% directly after the update, it's still there, and I've been on the internet, etc. It wasn't a major software overhaul, just a couple of bug fixes to touch and something else, and a bit of stability-fairly small and quick.
#Samsung s7 battery drain update
I just took the bug fix update this morning, about 2 hours ago. Hope to hear from other users and especially telus. Whereas it would lose around 1% over night, the phone now loses more than 10% (around 7h sleep). The issue btw extends to the deep sleep of the phone. It's really frustrating, the battery life was amazing before. I would go as far as exchanging my phone for another unit even though I know Telus won't do it. Looks like a Samsung issue, however I still wanted to post here and a) read what telus has to say, b) warn people who have not made the update yet (ignore it for now!) and c) whether it is possible to revert to the February/factory version of the installed operating system without violating the warranty. I've been reading online, mainly on xda, and many people are reporting this issue with Canadian, US and European versions of the phone. The processes/services 'Android system' and 'Android OS' now account for 25-50% of the battery usage, whereas before they were barely listed. Ever since the update, background battery drain increased significantly for me. I own the S7 and installed it right away.
Telus recently (April 18) released the April update for the S7 and the Edge.
