Samsung galaxy tablet 4 battery drainage issues

[ThunderDark]

My Samsung Galaxy tablet 4 has major drainage issues like i can use the tablet normally but once it hits like 68% ish battery mark it drains so fast and it has been like this for awhile now. Awhile back my battery had a drainage issue and i sent it to samsung for a free repair (under warranty) and it worked for awhile and all of the sudden it went from if my battery was on 20% battery it would drain super quickly like how it is now instead its worse! It does that around the 68% ish percent mark and i have tried many things my last options are buying a new charger or replacing the battery. I am wondering if there is a way to fix this battery drain issue without going to those lengths.

Looks like the battery is bad. Buy and replace the battery.

You're probably killing the battery by constantly draining it to 20% - lithium batteries don't hold up well if regularly drained past 40%. A constant 20% bottom level should give you about 6 months. (Never dropping it below 50% should give you 10 years or more.)
