| 29 Apparent voltage thresholds for UI battery icon change, determined by powering | |
| 30 a decased phone from a bench power supply, turning the voltage knob, rebooting | |
| 31 the phone each time and observing the battery icon: | |
| 32 | |
| 33 from 3 to 4 bars: between 3.88 and 3.89 V | |
| 34 from 2 to 3 bars: between 3.77 and 3.78 V | |
| 35 from 1 to 2 bars: between 3.72 and 3.73 V | |
| 36 from 0 to 1 bar: between 3.52 and 3.53 V | |
| 37 "Battery Low" on boot: between 3.51 and 3.52 V | |
| 38 | |
| 39 Below 3.37 V Pirelli's fw refuses to boot: starts, but then immediately powers | |
| 40 off. |
