Battery Drain In R197 Sp8
« on: December 01, 2007, 03:22:14 pm »
Being very happy with pdaXrom on my 860 I wanted to work(!) with it on the
road.

Well. BUMMER. I had it suspended in the evening and it would not wake up, not even boot
again in the morning. After some investigation I found the battery was comlpetely drained.

Some experimentation showed, that my Z sucked power while sleeping.
Over night it would return to 100%, reported in /proc/apm.
Only a few hours later, disconneted from the AC plug but suspended, it was down to 45 %.

Cacko and Angstrom did not behave that way.

Is this a known issue? Can I provide further info for someone 'who just knows'?

860er, pdaXrom r197 sp8, 1 SD card, 1 CF card, no wifi connected.

Some numbers:

Before I went to bed
> cat /proc/apm
1.13 1.2 0x02 0x00 0x00 0x01 95% -1

suspend Z

In the morning
> cat /proc/apm
1.13 1.2 0x02 0x00 0x02 0x04 5% -1

plug in AC; wait about 10 MINUTES ?!
> cat /proc/apm
1.13 1.2 0x02 0x01 0x03 0x08 100% -1

Hmm. What do these numbers mean? Is there a serious
bug in apm? Or do these numbers indicate a dying battery?

Any hints appreciated

I have noticed a similar thing, but only If I suspend while powered from the mains and then disconnect the mains.  If I suspend while not being powered from the mains then it seems to suspend fine and doesn't eat the battery.
