I am loving DjeMBeY's Modified, Slim, ROM, MK8
more and more!
I cannot, after 3 days and nights, find fault with it. I am using it with the default talexop kernel on Samsung's Power Saving mode with a standard, not extended, battery and so far the performance has been excellent and my battery usage has gone down from previous ROMs.
Here are 2 screenshots from this morning...
Overall battery usage since last charge. Average use. Google Services, (not shown), are 3%
Overnight, idle, with all services running and Wi-Fi connected and just sound off = 2% drop in battery over almost 5 hours and this is the worst reading of the last 3 nights.
This is easily, by far and away, the best Android 4.3
ROM that I've had.
