Yes it is bro.

bro, don forget the 2% drainage is for single sim 2G mode.
if dual sim 3G on lagi, cannot tahan till 5pm, unless u put it idle from 9am-5pm. pls rdy a external battery in your car else u cant use it while jamming on the way home. 

Some apps need root to run like Titanium Backup. Used it to delete the Mwarranty which was bugging me to register warranty on every restart after I hard reset the phone although the dealer already did the registration on the app itself.

Drainage is because the phone does not go into deep sleep at all, at least for my case. It is running at 1001mhz constantly according to CPUSPY. If it is not the apps I install causing this, it is the fault of the kernel, and without software update from Ninetology or custom rom, we may be screwed.

wait for the guide to undervolt/underclock. there is an app used to control these things,any1 know the name?

Rooted liao

Removed all the Go-Launcher stuff, QQ Browser and antivirus

what kind of bugs? proc speed stuck?
if this is the case can it be solve with smartass cpu control?

Haha...new kernel with old rom causing the problem?
Restart hp then,the must do step for android os.

If you root using the tool mentioned before, you can unroot from the same tool.

do not root if u intend to claim 1 to 1 exchange warranty in 3 months time.
but i dont think u will spend rm200-300 to repair the mobo (perhaps they hv spare part in stock) if its burnt within 1 yr for this rm500 hp 

That bad meh? Mine with wifi also not that bad.

35min on battery got 93% left

In comparison, my Huawei got ~70% left. waffak

What apps you got running?

try to disable QQ doctor, use nova launcher.
no need battery saver etc.

Lumia 620 less RAM, less apps, less freedom.
