Why is my battery draining so fast?
I got given a Samsung Galaxy Tab S 8.4 (SM-T705) as the owner told me, that the battery is draining very fast (with a full charge it only lasts up to 1 day in idle).
I bought a replacement battery and changed it in no time. Now it lasts 2 days in idle mode, so only one day more than with the old battery.
What have I done so far?
I checked all the running apps and disabled most of them, which are not being used anyway. This did unfortunately not improve the battery life of the tablet, so I did some research on it and found out that other people were having the same issue. Some of them changed some IC or the whole mainboard which did fix the problem, so I'm guessing that a specific part on the mainboard is causing this issue.
Now I'm looking for a mainboard replacement as I don't want to fiddle around with the single components on the mainboard. Does anybody know whether there are different revisions of this mainboard and how to recognize them?
