good question id like to know as well. I just picked up my external charger today and which brings my total to 4 batteries 2 std and 2 extended I know overkill

 

I'd like to know too.

 

Count me in for wanting to know

 

Maybe no one knows for sure like us lol

 

Just forget about all this battery calibration nonsense. It makes zero difference in battery performance.

 

Battery calibration just makes the battery gauge more accurate, but doesn't give your batteries more fuel.

Inaccurate reporting could cause the phone to only charge to 97% instead of 100% or turnoff at 3% instead of 0% so you can see small improvements in life, but it isn't big enough to be a major concern compared to the ability to swap batteries.

 

My battery life has significantly improved over the few weeks that I have owned this phone. Again, it's likely just the REPORTING that's improved, but I hardly ever need to charge it during the day anymore. When I first got it, I was down to 20% or so by the end of the work day, so I'd have to charge it to make it through the evening.

 

Here is what I get on Wifi.









I'll post what I get on 4G only soon.

 

every android phone Ive owned I had extra batteries that I cycled through an external charger . Eris, Incredible , Thunderbolt, Rezound and now Nexus . I can tell you without any doubt when I charge my battery on the external charger it lasts a little longer . I hate plugging my phone in so when I run out of battery juice I power it down and pop in a new battery then throw the dead one on the charger. It makes my life so much easier not dealing with chargers the only charger I use is in my car for when I'm doing heavy navigation and streaming on longer drives .. The whole battery calibrating things is bogus imo maybe if you were planning on keeping the battery for 5 years it might matter but most here upgrade there phone every 10-20months it's not gonna matter
