[Q] High CPU usage with battery drain , sever lag & freezing !!
I have :
Samsung Galaxy Note 2 N7100 32GB
Omega ROM v14 4.1.2
which I got 7 months ago . I rooted it few days after I got it and installed latest Omega ROM at that time and some later versions of Omega ROMs and stayed on v14 for long time with stock kernel . The device was running normally and smoothly till a week ago when the device suddenly started to lags and freezes and overheats with late response to touch and typing and opening apps .
During this week I installed cool tool and system tuner to monitor the CPU load and temperature I noticed that the CPU load is between 90 - 98% almost all the time with fast battery drain and the device freezes when the load reach 100 % ( not always ) even if I'm not running any app and sometimes the screen does't turn on after turning off till I force restart or remove the battery and put it back . Then I installed latest Omega ROM v16 with stock kernel with wiping cache and dalvik cache without full/factory wipe but the problem still there .
I Installed latest Perseus kernel to have some contol over the CPU and tried to change the max frequency up and down with no benefit !! .
I was thinking about Note 2 sudden death syndrome ( SDS ) but my device is internal 32GB version which means it is unlikely to get SDS and eMMC check showed No. Sane chip .
So, I hope to find a solution as I like my Note 2 and I have no interest to change it .
Thank you all
