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.

That 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.

If it's known the battery API should do a non linear mapping before returning the number.

How are you liking it? I wanna get a new phone soon, and I'm torn between a Pixel 3a and one of the Cat phones.

They're just your typical Android phones. Nothing special. medium resolution touch screen, a little bit of extra heavy plastic on the case. The usual OEM crapware is permanently installed on the device, and sending analytics back to the mothership.

If you buy it directly from Catphones, you just get the usual Google crapware, which can be disabled. Plus an "app store", which you don't have to use. I installed F-Droid and removed all the Google apps, and use only F-Droid open source apps.

Do you by any chance also pack light for trips? Have fairly empty pockets? Genuinely interested.

What a surprising question. Why? I always have a wallet, keys (in a coinpurse which sometimes has coins too) and a phone, and very rarely anything else. Sometimes I pack light, sometimes heavy -- enough so that I've been made fun of for both. I carry a backpack around a lot, full mostly of a laptop, umbrella and jacket. Bogotá rains a lot.

Interesting, thanks. Asking because I have a pet theory about phone charging anxiety being related being over prepared in general and visa versa.
