I have an Idea what could cause the battery problem, but I wanted to look at the schematic first. Short question offtopic: Which program is best to view the Schematic...

Ok. Thanks. I'll take a closer look :)

Could it have been a short on the board between C15 and IC2 (or C4 and IC2)? There the solder joints were a bit close together or slightly connected. I...
