Grand 2 battery discharge

My Grand 2 would discharge in 20 hrs even if I charge it for complete 3 hours.
Is it because I am using a 1.5 amp charger or something is wrong with my Phone.
Also I am on Wi-Fi for most of the day so is it possible that my battery may drain due to it?

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

M9 5.1 update causes discharge while on charger

Since the T-Mobile 5.1 update, my phone charges to full, then begins to discharge while still plugged in. Simply unplugging and plugging back in starts charging again. Is there going to be an update or something else to fix this?
