I would think this is by design; a lithium battery below some minimum cell voltage is probably damaged and should not be charged.
I don't know how the PMIC decides the charge profile, though, so I don't know what it might be doing. > On Nov 13, 2016, at 14:05 , William Hermans <yyrk...@gmail.com> wrote: > > We've been observing that the PMIC does not charge a battery that is below a > certain voltage threshold.
