I notice that when I get 2 battery bars or 1 - the phone starts working slow and apps load longer and etc. I SEEMS to be like its meant to do it to save battery, but I am not sure. I noticed this a while ago, but I tested it today and when I had 1 bar left - all the apps were loading slow. So, it could be a battery profile.
Is there any way to disable this crap and let it drain at maximum rate and give maximum performance until the end? It will cost me shower battery life, but I don't care!
