Seeing my phone battery below 50% makes me faintly anxious because it seems like it always discharges faster from 30% to 0% than from 100% to 70%. It's the unpredictability of discharge rate rather than merely having a low battery.
- waste_monk 7y agoThat is what's happening - I'm not an electronics person but my vague understanding is modern li-ion batteries output e.g. 3.5v but actually hold between 2.x and 4.x volts, and regulate power up or down. When it's full it's easier to push current through, when it's nearly empty it has to work a lot harder to supply power and consequently drains faster.
