I seem to be able to reproduce it now, which is progress. I've attached a CSV that contains readings from APM and all the files in the charger's directory in /sys.
The good news is that the problem is detectible in software; apm reports: Off-line, battery status low: 49% (1d+3:40:00) when charger_type contains: charger 1A mode 1A This can never be the right state for the phone to be in... It is losing charge slowly over time in this state, though at a rate of less than 1% per hour. (It dropped from 50 to 49%, then I waited 45 minutes for a change, and got bored) Here is the contents of dump_regs: 13 84 00 00 00 00 00 80 00 00 00 00 00 d3 aa 4a 15 44 ff 01 00 07 00 00 02 08 6b 01 00 0a 1b 02 00 22 2f 01 00 22 00 00 3f 01 05 20 11 18 02 18 02 00 00 00 00 15 00 15 01 16 01 00 00 ff 3f 00 00 17 63 e6 28 19 ff ff 00 02 00 33 20 50 19 00 00 08 00 00 0e a3 00 f0 00 42 04 23 00 20 06 08 7f 7f 3f 07 3f 1f ff 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 c9 72 d9 0a 27 60 08 c0 b8 13 c0 03 07 00 00 00 03 e2 ff fa 62 11 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 I haven't forgotten about the suggested kernel patch + charger override; I just haven't had time to figure out how to patch, compile and package a new kernel yet... -Rusty Stefan Fröbe wrote: > Hi everybody, > > I experienced something similar yesterday with my Freerunner running a > recent andy+mwester kernel: > > After plugging the turned off phone with about 30% battery left into > the wall charger at night, I woke up to realize the battery had become > completely drained!
