Mi2 doesn't go on in the morning

Oct 28, 2013
Hi all,

My mi2 is having some issues. I put in on the charger in the evening, but then in the morning it doesn't go on anymore. This also means that my alarm doesnt go off and that I can't e called anymore. When I long press the power button, it reboots and then everything works again. I've tried multiple ROMs, a few CM10.2 ROMS and the "stock" multilanguage ROM. Does someone have a idea how to fix this or just how to test how long it stays on?
