i replaced u2, and mostfet ic. nothing changed.

i replaced c242_rf, because it was burned.

what do you think, this short was killed the u25_rf or the pmic, or any component?

thanks!

May I ask for the interval of every % in when using it?

in standby mode drain fast too.

during the night from 100% to drain the battery was empty.

Maybe 30min 3-4% drain in standby mode.
