Plug [Q] Battery charge won't get past 1%

Hei, i have a problem: it won't charge. Battery was at 20% when i went to sleep and this moning i found it powered off, plugged in charger and it won't get past 1%. Any ideas? I'm on [LINARO] Resurrection Remix® Kitkat v5.0.8 [Update 20140411], stock 4.2.2 kernel. Thanks!
EDIT 1- I removed the battery for 5 minutes or so and it now charges. but it seems to go very slow. Still don't know what caused it to behave like this..
