Battery life too short (noob)

As @librem5 replied recently:

@librem5

I turned off phone (had around 20% battery), charged until red LED off (took about 4 hrs).

@dos

until it reaches termination current

Just found additional expert interpretation of this relatively “simple” term that you wrote here: Test of Battery Charge Termination Test or in shorter variant here: “In my charger reviews I often comment on a high termination current, and says that the battery will not be fully charged, but I do not specify more precise what that means.”

… “means”, in addition, that the Librem 5 Linux phone have his own built in charger:

@dos

charging extra batteries can be easily done via the phone itself. If you use a powerful enough power supply with high enough input current limit, you should be able to take the battery off while keeping the phone fully operational, powered from USB. Then you can just put the other battery in and it should simply start to charge.

@pit, thanks for your post (even if this sounds somehow strange from my side)! I certainly understood, appreciate, and actually liked your main message (although skipped it), your very main point here:
