MIUI on Defy+ - Battery Issue

Dec 4, 2011
Hi all,

I've installed MIUI 1.12.2 on my brand new MB526 (Defy+).
Everything fine apart from a bug in battery charge... the battery couldn't show a charge percentage higher than 85-87%, even after hours and hours, and the green light never shows up.
This ratio is strangely similar to the one existing between the capacity of the batteries installed in the MB525 (1500mAh) and MB526 (1700mAh).
Tried to wipe battery stats, and also running "battery calibration" app, with no results.
Is this simply a indication bug (i.e., the battery is actually charged), and is there any workaround or patch?
