Ok first off, I am using Ivans Eris_Official_1.0 with absolutely no issues. I get 10-12 hours of use on a full battery with moderate usage. A couple of weeks back I decided I wanted to play around with some other roms so I created a Nand backup and experimented with a few roms. I then decided to go back to my Eris_Official by flashing my Nand Backup that I had created. The issue I am having is that after flashing my Nand backup, my battery is draining at unimaginable speed. On a full charge, I only get 3-4 hours before it dies. And that is without even using the phone. and it takes almost 8 hours to charge it to full again. I then have to resort to flashing a fresh rom and starting all over. I love knowing that I have a full backup of my system but it is almost useless if it is going to drain the battery that fast. Anyone else experience this?
