Galaxy S2 i9100 gets hot and sod

[jt_se7en]

Hi,

After days of searching the internet and reading forums i finally found this forum and think my problem is right in here.
The Power IC next to the camera of my Galaxy S2 gets hot at random times while charging and while normal using the phone and if the i9100 goes into standby i can't wake it up.
If i restart it again by taking out and in again the battery it's drain by 20-30%.
This problem is not related to firmware, kernel, battery, charger or usb charging port. I also cleaned the mainboard in isopropanol but it's still the same.

Thank you for your help and sorry for my bad english

All you need to do is install Titanium Backup and freeze as many of the following apps as you don't need. I have frozen them all and the device is working very smoothly.

And thats it... No more Lock screen lagging when trying to unlock your phone.

Also I would recommend downloading widget locker and using that as your lock screen it works amazingly smoothly and has tons of customization.
