Here is Pirelli's version of the a_pwr_thresholds[] array (see pwr_cust.c in the MV100 source), fished out of their firmware images: Table begins at flash address 0x54C0C8 in fw version D910.0.3.98 Table begins at flash address 0x54B684 in fw version D910.0.3.99d 4170 100 4120 95 4070 90 4030 85 3964 80 3930 75 3900 70 3882 65 3847 60 3805 55 3786 50 3771 45 3759 40 3750 35 3745 30 3737 25 3719 20 3688 15 3663 10 3539 5 3370 0 Apparent voltage thresholds for UI battery icon change, determined by powering a decased phone from a bench power supply, turning the voltage knob, rebooting the phone each time and observing the battery icon: from 3 to 4 bars: between 3.88 and 3.89 V from 2 to 3 bars: between 3.77 and 3.78 V from 1 to 2 bars: between 3.72 and 3.73 V from 0 to 1 bar: between 3.52 and 3.53 V "Battery Low" on boot: between 3.51 and 3.52 V Below 3.37 V Pirelli's fw refuses to boot: starts, but then immediately powers off.
