Hello!
A while ago (around end of August) I bought an Andida battery that claims to have 1980mAh and I felt it gives me marginal better/longer battery life - so far so good.
After last update to the latest uv-ironkrnL-mod(version from 23rd of Dec) by vodonka (see my sig) I changed back to the stock battery (fully loaded in external charger and wiped battery stats - of course) and got SODs - especially when activating/deactivating Bluetooth and/or wlan but also out of the blue...
I tried it for 2 battery cycles - but I got SOD - very annoying.
After changing back to the Andida battery didn't have SOD/BSOD or end call issues again - it seems the battery gives me more stable voltage - I assume...
And it gets less hot than the stock battery while charging - meaning to the touch - not the not working/not existing temp sensor of the Andida battery of course...
So for less than US$10 including free worldwide shipping(from obostore) - this isn't a bad deal...
