After using it for a couple of days now, I noticed an obvious increase in battery life so I didn't even bother do any tests. I think I'm considered an "average" user. I usually talk on the phone with the gf for about 3-5 hours a day, browse the web on 3G or wifi for about 1-2 hours , text, listen to music, remote desktop and ssh, upload and download via ftp, tether, and play some emulators. Usually my OEM battery would hit 1-2% in the late evening and I would need to recharge it but with Andida battery it'll last up till around 10 or 11. (Unplugged around 7-8am)
So far all positives review from xda members. If any one is interested in upgrading to a new cheap battery, give the andida battery a try.
