Default Incorrect Battery readings

Anyone else have this problem, where the phone will automatically shut off. When it does that, I enter bootloader, and it says battery is low, did a battery wipe in recovery, onto to see the battery, which was at 40%, now at 2%... Any reason why it's giving such a discrepancy....

Running Energy Rom with stock kernel.

Download "Battery Calibration" from market. https://play.google.com/store/apps/details?id=com.nema.batterycalibration

Charge your phone until it says 100% and the light turns green. Unplug your phone. Plug it back in until the light turns green again. Open this app and calibrate your battery.

Should fix the issue

That is a nice trick, but won't fix incorrect battery readings.

funny thing, i tried that....
it likes to stick at 60% for like 7 hours, only to drop the ball and then show out of battery after it shuts down....

could always treat it like a laptop battery to calibrate it, Charge it fully, let it go dead and keep the battery dead for at least 6 hours. Charge it up and let it stay charged for several hours before unplugging it.

Or try and take the battery out, hold the power button for a few seconds, reinsert the battery and try again. These things sometimes help on laptops, figured it couldnt hurt here.

My solution is just keep it plugged in pretty much most of the time, and drain it weekly....

I regularly calibrate my battery weekly. Although, the recovery I use displays battery percentage and it's often different (more accurate) then what is displayed on my battery icon.
