Anyone have ideas?
i have the same problem as yours,100% same but it happened to me after installing custom rom on android 4.3..
battery jump from 20% to 0% immediately.. with no mercy, phone shuts off at any cost and start again at 1% after turned on and charged.
i still use the original battery (not replaced it yet) and in battery health test said it's good, no need to replace it.
now i'm trying to find the fix by myself.. maybe i have messed up something with my phone..
