Hi,

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.
