Hello everyone, When I bought my Galaxy Mini S5570 it came with Android 2.2. I used AnTuTu CPU Master (Free) to keep the processor ON-DEMAND. So its speed would vary from 245 MHz to 600 MHz, which saves a lot of battery. Now, the phone was update to version 2.3.6 via Samsung Kies. I lost the root (but rooted it again) and now I wonder if it's worth keeping CPU Master installed, or if this new firmware does the job of keeping the processor ON-DEMAND by itself, as I've heard somewhere. Thanks!
