Tab s3 battery drain since pie update

[drmoore]

Recently updated my tab s3 to android pie and now my battery drains in standby mode in 2 days whereas on oreo it would have lasted weeks. I have tried a full factory reset which has not solved the issue. Has anyone any ideas on how to fix this issue or is it a case of waiting on Samsung to release a patch.

hi @drmoore , did you make a wipe cache partition after the update to clear all corrupted files ?

Please read this post :

Hi Cassidy007 I cleared the cache before I carried out factory reset, I have just cleared cache again and will see how it goes.

Device care shows 4 apps using total of 6% battery yet graph shows how my tab has lost 50% battery power in standby mode since charged

Same issu after update battery drain dramatically in standby. I test un airplane mode for checking a connectivity issue or other.

I have the same issue as well. I performed a hard reset, still doesn't help.
It was not like this before the update.

This seems to have improved battery life by turning the following off

Settings->Biometrics and security ->Location -> Improve Accuracy ->Turn Wifi Scanning OFF

Settings->Biometrics and security ->Location -> Improve Accuracy ->Turn Bluetooth Scanning OFF

Update the only thing that stops battery drain is to place the device in flight mode when not being used. Device only drops 1% in 24hrs when flight mode activated.

Same problem here. Battery life was ok before the update.
