Yes I did. I installed it since my previous firmware. And I've been using the only stable software(s) from there. And with the old firmware it doesn't have the power problem at all. I don't see why this update doesn't like those software(s). I used the same apps with the 1.0 and yes my battery last me 36Hours + with my usage. Now It barely able getting through 8hours without using much but SMS. SMS alone redline my CPU lol.. This is crazy. Is there away to get rid of this update?
