Smartphone charging madness ;-)

[Robse]

A new twist on charging.   To my great amazement, I observed that my "rider" phone was apparently only charged to 80% - this happened when I had it charging for 1.5 hours (on turbo charge ) See the picture below - apparently the manufacturer of the mobile phone means, that it is smart to charge to 80% ... and then wait with the last 20% until just before the gizmo needs to be used - if their AI software can learn my habits - which it can't ;-)   And because of this idiocy, I start a ride with a phone that has no power for the whole tour - which brings to mind the thing with only charging the wheel to 80% ;-) I think it's completely *"*¤%"

With a rooted phone you can use BatteryChargeLimit and set it to automatically turn off charging at whatever you want. I set it to ~4.2v.

Those 15% aren't worth the trouble. Use a powerbank instead. You get faster charging because you stay below 4.2v and your pack will not lose significant capacity over the years.

Its different with phones as there's (in most cases) only one cell. It does preserve longevity To only charge up To 80%. But I do concur its not really worth it since usually the life time of the battery is not much less than that of the Phone - apple products aside. Those go on for longer than androids do Generally speaking
