Hello, I'm having issues with what I think is battery readout miscalibration on the HTC One M9.
The battery life is relatively short (several hours) and it consistently exhibits the following behavior. At 60-70% it reboots but then continues to work, and then at 40-50% it dies and displays "0%" battery message when trying to boot.
For charging I am using either a Tronsmart Quick Charge 2.0 wall charger or a 1500mAh power bank that provides 5v 2A.
As soon as I plug the phone in for charging, it tells me the battery level is where it was before shutting down, e.g. 40-50%.
I am attaching a picture where the phone shut down, was kept off for a while, and then started charging.
I am running Vodafone UK Marshmallow RUU, but the same issue happens with CM13 and Android Revolution HD.
I believe it to be related to the fact that the pmi8994 battery controller incorrectly reads what actually is close to 0% battery as being 40% or higher, and as such also reading 100% when the actual battery is less than that.
I have tried following these steps in the M8 forum, but I don't see a visible result. But I am open to other suggestions on how to reset this power management controller.
