Not sure why you are marking this as resolved... There is obviously an issue that you guys are ignoring. Putting the phone in Safe Mode DOESN'T WORK. Wiping the cache partition DOESN'T WORK. Doing a factory reset DOESN'T WORK. Following tips to conserve the battery life DOESN'T WORK. The severe battery drain is still an issue for A TON OF PEOPLE. You can Google "Oreo battery drain", and find 553,00 results. I think it's safe to say that it is an issue that was caused by the Oreo update, and you people are trying to get around it by saying it's a hardware issue. Ridiculous!
Tell your management to fix the battery issue, i know that you guys did it because of the upcoming release of note 9, i switched to s8 thinking that you guys would not do such thing, I will file a case against samsung through BBB, you guys really think we will not figure this out huh??
Like many others, I have been "disgruntled" by the rapid battery drains after the update to Oreo.. I have been avoiding selecting "MAX" on the Power Saving mode, because of how it limits the phone, but today I tried it, just to see what all it would disable.. as it was going through each setting, I noticed at the bottom of the list it got to "Biometrics" and said +550 min !!! I had my phone set for both Finger and Pin screen unlock, and it has been fine that way for some time. I disabled the Finger unlock (under Lock Screen and Security > Screen Lock type) and now my battery drain issue appears to be resolved. My battery had previously dropped from 98% to 83% in approx 1 hr, and since disabling the Fingerprint unlock, it has only dropped 1% in approx 2 hrs !!
I agree! I'm so irritated, we are told to take it in for service, is Samsung paying for that? My $800 phone is ruined ! Is their a class action lawsuit against Samsung? I'd like in on it before I switch to Apple !
I fixed this issue myself as of today and its very quite simple. The issue lies in Gear VR Services, it was using 110% of my battery and was draining ram.
First, wipe your cache partition.
Then use "Package Disabler Pro" from google play, it costs only $3.49 and is worth it, especially since you won't have to root your device.
Grant the app admin permissions when prompted. Check the checkbox for Gear VR Services, and done. You just saved your battery and saved your phone's performance. The app will vanish from your app list and will only be visible in the package Disabler app.
This an issue with the Samsung version of the Oreo OS for galaxy s7 edge and needs to be repaired by the Samsung developers.
