New battery discharge in 2 stages

Hey guys

I have replaced my opo battery one month ago, at the beginning I thought it was a ROM problem when I realized it happens with every existing ROM for opo:

Basically the new battery discharge from 100 to 0 in about 3 hours and the phone turns off, if I wait 5 minutes and I turn the phone on I will have the battery back to 65% which discharge in about 3 more hours.

I did already the calibration and stuff like that...it doesn't work.

Any suggestions?



Thanks
