I removed the BME replacement, on stock BME it calibrated without any hassle, without even turning off BME.
I measured 1282 mAh, so much less than given. But it's not much less than the original battery, and the price is almost the same, so I'll keep it.
On GSM, normal usage, connecting to WiFi on-demand (my normal usages) I get up to 2 days of use.
Hi!
I made a custom battery. I have some N9 battery with 1450mAh capacity. Replaced the battery protect circuit with the bl-5j's. Now I have a wonderful new battery.
The only problem, that I cannot calibrate it.
My method was:
1. Charge it full.
2. sudo gainroot; sh bq27200.sh
3. waiting for battery low alert.
4. sudo gainroot sh bq27200.sh 5
5. Wait until it switch off..
What did I wrong? After switch it back It says I have 1713mAh. But the status area indicator says 1292mAh. It is not consistant.
I'm also having some battery status reporting trouble; a new battery, the trouble started after a few weeks of use -- stopping to charge at 80% (as reported by battery-eye / status area), after clearing the data in battery eye, not seeing any charge info at all, etc.
At first I suspected the battery, but over the past few days I've done some calibration using bnf/bq27200.sh, and the battery itself seems to be doing great -- the numbers reported by the scripts are behaving consistently, and I'm getting good use out of each charge. However, the reporting in battery eye / hal / status area is still acting weird.
1. Is the calibration supposed to affect those, or are there two separate battery-status-reporting entities here?
2. I'm not even sure if I'm using stock BME or BME replacement -- how can I check? (I'm on CSSU Stable, switched to kernel-power-53 only about a month before getting the new battery; I didn't explicitly switch to BME replacement, but it's not clear to me if that happens automatically with kp53?)

On those last values the n900 turns off. GSM was turned off and Brightness was on the low level. But EDV1 and VDQ was not changed.

Pali: Add two gconf values. First (bool) to enable shutdown device at EDV1 flag, second (int) to shutdown device at specified <= voltage. Default values: bool = true and int = 3150 (as suggested)
But not know which parameters must be changed with the gconf.
I use BME re and kp53.
