Define upper and lower limit for charge state

Hardware Librem 5
3

Thanks for sharing the link. I learned 2 things:

  1. The battery is already not being charged to 100%, so it should last longer than most smartphone batteries already. Most batteries charge to 4.2V, and that is what the phone stops at, but the battery in the Librem 5 can go to 4.35v. So stopping charge at 80% in its current configuration is redundant. If someone takes out (or maybe just keep the kill switch on) the cell modem, it can be charged to its true 100% for a longer time between charges. This might be useful for someone who does not need cell service. Or only needs the cell modem after the battery has been discharged below a certain level. The cell modem may be able to operate outside of its spec, but I would keep a spare modem around and be prepared to change it yourself. Problems resulting from over voltage may not be obvious, like loosing connectivity every once and a while. If support is needed, let people know about the modification so that they can diagnose the problem accurately.

  2. It is possible to disable the red LED by changing a charge controller setting. Personally, I would rather have the charge controller inform me of its status. Also, if Purism’s support is needed, inform them of this change if anything strange happens with the battery so that they can diagnose the problem accurately.
