So 3 days ago I bought a brand new G2 off cragislist (still had all the peel off stickers) for 200. The guy said he had it replaced by t-mobile cause his old phone didn't send mms or something. His daughter bought him a newer phone so he decided to sell this one. Anyway, he gave me his old battery and battery cover since tmo didn't include it.
when I first got it the battery life was terrible, and I didn't even have the data plan hooked up yet. After connecting to my wifi and surfing/downloading apps, about 10% drained in less than a few minutes. I let it drop to 30% and charged it fully (first time). The first thing I noticed was that it was kinda "stuck" at 100% for a while... then it dropped to about 96% and started draining from there. I then made sure to turn all the data and wifi off and went to sleep when it was at 78%. Woke up 8 hours later and it dropped to 71.
Now my question is, should I have charged it all the way, then played with it til it died, then recharge it again? Or is that unnecessary since the battery is old anyway and it doesn't matter if its a new phone?
After a few more charges, it seems like the battery is a bit better but I'd still like for it to last longer. I still feel like I'm getting inaccurate readings though. Still gets stuck at 100%, then at 70%. Should I let it die all the way to calibrate the battery?
Also, I heard rooting the phone and flashing the cm7 rom will improve battery life, is that true? Cause I had the mytouch3G a while ago so I'm sorta familiar with the rooting process but I didn't notice any battery improvements.
Thanks.
edit: the phone came with the 2.3.3 firmware
