GTA04 battery can measure power consumption very well. Most important files
You can dump current_now to see actual consumption.
You can use charge_now to see how much of battery was eaten during suspend.
There is somewhere mail from Neil Brown, maybe this one will lead you there:
if you want to take look at code search for "avgCurrent" here:
So with these 2 files you can measure exact power consumption. You should see
values ~200mA when the phone is running and ~15mA in suspend.
To lower the power to minimum please make sure:
1/ rfkill all that you dont currently use - you should do:
rfkill block gps
rfkill block bluetooth
2/ use latest Neil Brown's kernel - it has enable_off_mode that saves ~7mA
3/ make sure that your sound card is setup correctly - specifically the
control 'Voice route' can eat ~5mA, see this commit:
Btw how do you build replicant? Are you using replicant git and howtos for it?
Do you have some custom patches? Is it possible to install it on single
