[Q] [q] charging with ROMs

I have had charging issues when using custom roms recently on my archos.

has anyone else had charging issues with customs? and if so, any workarounds?

last one i had was on ics blue - on charge overnight @31% charge before sleep and when i woke, display was still showing 31%
have had this issue with clean and fast too.

currently on stock rooted 4.0.25

thanks
