After i start WiFi, or telephone make any data access to the internet, processor's speed raise up to 800MHz and never step down again. After that, telephone starts to heat up and drain battery (60% in 2 hours).
Im checking CPU speed through CPU spy, and CPU notify. Both says telephone uses 800MHz only. When i turn off any data connections and reboot phone, everything goes normal and CPU speed was low.
After that i checked which process drain CPU and it was process named debuggerd. So i comment its starting line in init.rc file, but it seems to be only a little bit better with heating, but nothing happened with CPU speed. Now the most draining process is zygote, but it seems to be some important process, so i doesnt try to kill it or disable his startup.
