Subject: [PATCH 0/7] Some fixes and improvments for cpcap battery and charger
Date: Sun, 7 Apr 2019 11:12:47 -0700 [thread overview]
Message-ID: <20190407181254.64537-1-tony@atomide.com> (raw)
Hi all,
I've been trying to figure out how come the coulomb counter on droid 4 is off
especially for the low power consumption values. Turns out the "coulomb counter"
values correlate better with average power consumption if we divide the value with
number of samples. Otherwise we have a curve instead of flat correlation between
the register values and power consumed. I have some patches coming up eventually to
fix that, but meanwhile I've noticed some minor issues in general that would be
good to have out of the way.
I've only tagged the first one with fixes tag, the other ones can certainly wait
for the merge window considering further changes are needed at least for low power
consumption values.
Regards,
Tony
