Io sto usando il LeanKernel, è uno spettacolo e ti riporto una cosa scritta da un utente sul post ufficiale di questo kernel:
I've been reading on different kernels last night I decided to put them to a short test on my Galaxy Nexus running euroskank's CM10. The test was with the phone under the same light, with Wifi close to the AP. I used the following for my test 60min of Standby, followed by 5 min of screen on, 5 min standby, 5 min screen on and 5 min standby. Each tested started ~1 min after a reboot and right after the battery % dropped to the next % with no other apps launched manually nor any interaction with the phone.
I know each Governor is different and it's not a perfect test.
Trenity with OnDemand Governor - 6% consumed
Popcorn with PegasusQ Governor - 4% consumed
Franco with OnDemand Governor - 5% consumed
LeanKernel with HotplugX Governor - 2% consumed
Very impressed by the results.
