Battery life too short (noob)

[Quarnero]

@pit

It loads 8h or so.

This isn’t truth. What I can confirm is below rate at +/− 5.0V/1.5A as only reliable truth. At least charging with this speed under 50-60% for sure (and without any overheating issues):

@irvinewade

So with the battery at, say, 20% it might be charging at 1.6A but with the battery at, say, 90% it might be charging at 0.4A give or take.

It doesn’t matter if Librem 5 on or completely turned off it stays charging its battery with a 1.5A current. And although I never actually measured time needed, my guess would be still something around four hours from 2% to 100% (or even less).

As confirmed long time ago:

@dos

The charging controller is configured to feed the battery with at most 1.5A.

Confired here again:

@dos

To be able to comfortably charge while using the phone, you need at least 1.5A there (and ideally 2A or more). Currently Librem 5 does not use any other voltages than 5V.

Only thing that I might add (out of the blue sky and IMHO) would be that BPP-L503 battery likes (looks like to me) to be constantly (and steady) charged with 1.5A (or having at least 7.5W from connected power supply just for itself, if this serves or might be taken as an additional explanation) rate. Actually all numbers within this post are exclusively related to Librem 5 battery only.
