Maybe it is remembered incorrectly. And in bq27000.pdf doc is written that this value is updated on a valid learning cycle. Try to discharge and then fully charge battery again.

what is reporting BME?

If so, how can you explain that :

Code:

-bash-2.05b# lshal -u /org/freedesktop/Hal/devices/computer_power_supply_battery_bq27200_0 | grep battery.charge_level.percentage && lshal -u /org/freedesktop/Hal/devices/bme | grep battery.charge_level.percentage
  battery.charge_level.percentage = 56  (0x38)  (int)
  battery.charge_level.percentage = 95  (0x5f)  (int)

And what is your opinion about the right and the false value ???

You can trust me, the right is the one reported by bme !!!

This is because BME calculate chage_level as charge_now / charge_full_design * 100 and bq report chage_level from chip. Chip define chage_level as charge_now / charge_full * 100
So If you have new battery percentage should be same. But if battery is not new percentage cannot be same.

Probably not. It's not that old to give zero values and keep working and working and working...
When I was writing previous post, I started playing a movie via WLAN from Mediatomb with all my accounts enabled and mail check... And battery is still not 0%.
