Had my Razr Maxx for two days and was wondering if this was good battery life.
Battery is at 70 per Battery Indicator Pro.
16 hours on battery - took off charger when I got up at 4:30 am.

Cell stand by 29% - time on 16 hours - no signal 20%.
Display 18% - 1 hr 50 mins.
Voice Calls 15% - 19 mins.
Android OS 13% - 30 mins.
Phone Idle 7% - 15 hrs.
Android System 6% - 11 mins.
Bluetooth was on 11.5 hrs.
Am running Galaxy Live Wallpaper.
Used Fresh Network when I got to work at 6 am.
CDMA only.
No GPS.
Had sim card removed while playing with another phone for an hour.
Had WiFi on for an hour.
Have a Smart Action to disable cellular data setup.
Am also syncing two gmail accounts.

If you're at 70% with 16 hours that should tell you its good.

That's insanely good. I'm such a heavy user my battery barely makes it through the day.

I got my Razr MAXX yesterday, fully charged it overnight. Woke up at 6am, battery was at 100%. It's 3:00pm now, and the battery is at 50%. Been using the phone quite a bit today, but don't think this is what I paid $300 for! Plaese tell me if I'm wrong...

The reason you are having less than expected battery life is because the battery isn't conditioned yet. Best way to do it is to charge it to 100% before using the first time. Then you discharge it as much as possible by using the flashlight all the time, turn on Bluetooth and GPS, wifi, etc. Then completely charge it. Do this for about a week and your battery life should get quite a bit better. Had to do it with both my stock battery and extended one for my Epic 4G Touch. Made all the difference in the world. The batteries do not come pre-conditioned from the manufacturer. Your mileage may vary though...

Actually don't do the above it doesn't help and if you do it too much you will hurt the battery. Also new Li-Ion batteries are conditioned when you get them. Keep it charged, keep the phone cool never hot, and never let the battery stay completely discharged.

If that is the case with Li-Ion batteries, then why did the manufacture say to do that as part of the conditioning process? Not meaning to be rude about it but conditioning a battery, Li-Ion or not, Is good for people that use the hell out of their phones. Same goes with car batteries. I aint saying to do it all the time with a cell phone but the first week aint going to mess it up. It is actually better on Li-Ion batteries to do complete cycles than partial. Do your research for yourself and see.

Also, my co-worker had an E4GT, with an extended battery like mine. I did the conditioning process that I described and that was recommended by the battery's MFG. My battery lasted almost TWO days. His would last about 18 hours off the charger. Proof is in the pudding.

Guys.. keep using your phone and let it cycle through normal charges for about a week. You should have better battery life. Android takes a while to learn where to stop your battery, and it often will undercharge it during the first few cycles.

I have two Traxxas R/C trucks. And they use Lithium Ion batteries. It is known that you never let them heat up excessively. Reason is heat will kill the life expectancy of lithium in a heart beat. Most of the time cutting its charge capacity in half. The same goes for letting it die. If the battery does not have a protection circuit built into the battery or on the phone it self and the battery drops below 3.2 volts per cell. Then the life will be cut. Lithium is a very touchy chemistry. In all of its current forms it needs to be handled and maintained properly.
