Our renowned dev mike1986 found out that Tegra 3 power management controls are broken in firmware 1.26 and he fixed it in his latest ROM (v1.2.2)

from what i could gather on his thread, Nvidia power control app was placed in a wrong folder

those who have tried this ROM, can you please report your situation now, Heat, battery, performance, flicker and glitches?

Instructions thanks to mike1986

1. Download resigned NvCPLSvc - http://xda3.androidrevolution.nl/db_...s/NvCPLSvc.apk

2. adb push NvCPLSvc.apk /system/app

3. reboot into recovery

4. Clear dalvik-cache

5. Boot system and check if system@app@NvCPLSvc.apk@classes.dex is in data/dalvik-cache

Fixed the power management on my own and it improved my battery life for about 10%-20%. It lasts a little bit more now but still have that battery drain.

Not sure but my old hd2 used less in standby (1-3mah) and my one x around 130mah according to battery monitor widget.
I know it's quadcore and no singelcore but I thought the companion core would save a lot.

can you explain how you fixed it on your own? placing the apk in the system/app folder?

Yes exactly.
That's what mike did to fix it. Hope some devs will be able to port some powermanager options etc from the transformer prime

Just check in the battery monitor app, In the graph you can see a white line which seems as it has a battery drain of 0ma in standby. I see this in every rom I use, even on stock.

For some reason HTC misplaced the .apk and put it in /system/bin instead of system/app

You will find it /system/bin/NvCPLSvc.apk and it needs moving to system/app.

For users who already have LeeDroiD installed, use a file manager with root access and move NvCPLSvc.apk from/system/bin to system/app and reboot.
