High CPU issue

[Guest oxyg3n89]

Hi here!

i rarely start new topics as google usually helps, but this time i have really strange behavior. Bought phone for cheap second hand and trying to fix now...

The phone boots up and everything works but CPU is always 99-100% ! i flashed new TPT, tried latest CM7, other roms...problem is still here.

In system info there are processes but none of them shows high usage. The lag is mostly noticeable in scrolling, 5-10 fps in main settings menu some other apps or home screen, keyboard delay a lot too. When quadrant bench is running, it does show very low results in 2D graphics (score 53 only) however CPU gets score 700. looks like adreno graphics broken, could this be? angry birds running well! this blade is real circus as other blade i own works with no issues.

Any help ?

1. Install atomic of custom rom.

2. Get advanced task killer, and set Autokill to every 30 mins.

3. Get juice defender.

And there you have it a very fast ZTE skate with great battery life!

I'm not sure if it's the same problem as you are using a custom ROM, but I had similar issues with high CPU usage after bootup on original Orange (UK) ROM ... have a read of:-

Yeah the only place I've seen similar was in the stock rom. Or perhaps early froyo - I don't quite recall. Certainly in no recent roms/

It was something to do with the light or prox sensor. I seem to recall having to cover it until the keypad backlight came on and then the phone was fine. So you could try that to see what happens?

latest post good one :) opened my phone, replugged and cleaned prox/light sensor connection and now my phone works perfectly. thanks ;)
