I've got the extended battery, and I'm absolutely shocked at how terrible it has been so far. How in the world is the battery life on this thing on par with the Thunderbolt with a stock battery!?!
(These images all resized automatically in my browser -- apologies ahead of time if they didn't in anyone else's).
As someone else mentioned, my phone dropped from 100% charge to 92% really, really quick. Like, 20 minutes IDLE quick. I was quite taken back when I checked my battery and saw it had dropped that quick. Insane, but I wonder if that's a calibration error.
I did stream 180 MB worth of Google Music today, some in 4G areas, some in 3G areas. I would say 60%+ of the time I was in a 3G area today, no fringe LTE coverage or anything. All in all, I would say today was a light usage day, as I was with my extended family and tried to be courteous with my phone usage, only pulling it out occasionally to check the time, or to look up the value of a few items my uncle was curious about on eBay. Combined with a total of 40 minutes Google Music, I would say I hardly used the thing today.
But what shocks me most is my second image and how terrible of a signal the Nexus tells me I have. Christ, let's be honest -- Verizon's network signal strength isn't the strongest at times, but really? 99% of the time today I had a poor signal? Something is seriously f@$ked up with Nexus' radio.
Seriously. That's unacceptable. I was all over, traveling major interstates for extended periods of time, in major cities... I passed dozens of cell towers today, and I apparently hardly ever had a strong signal. That's incredibly awful, and that's absolutely wrong.
I'm going to drain my battery most of/all the way tonight. I'm hoping that as I get down to the last few percentage points of my battery, the device will be like "Oh, wait, I had that all wrong. I'll let this sit on 2% remaining for a few hours -- my bad" and finally get its calibration crap in order. I haven't had the opportunity/time to fully discharge and recharge the battery yet, so hopefully that will help.
Otherwise... man, not looking too good.
edit: Also, I noticed my battery made little jumps up throughout the day. No charger at all -- wtf Nexus? Haha.
