I returned my Nexus after about 24hrs and 4 full charge cycles from 0% to 100% (on purpose for the most part)...
The phone is a absolute beast and Apple is going to have some serious competition with the next gen android devices. I am an iphone user from day 1 and the Nexus I would say is all around a better phone than the 4s EXCEPT for battery life. But from what i am hearing from many android users over there is that it takes a good full week until your battery is fully in sync with the phone. It could be showing you 10% charge left but it actually has 40 or 50%+ . I would have given it the full week if i knew this! With the iphones iphones its the same thing your battery will get better over the first week but the differences are not that large.
A few observations -
1. I know what all the fuss is now about with the android notification system. It is unbelievable and its in my mind constantly now since i have experienced it and I may purchase the phone again just for that alone
2. ICS is as smooth as iOS all around, no choppiness at all, no lag..
3. Adjusting system settings are quick and easy, very nice...
4. 4G LTE on Verion is just sick, i was averaging around 20mb down/10mb up consistently with about half of my testing running 30mbs down many times
5. I did not have any reception issues as others have said, it was much much better than my iphone 4 especially indoors.
6. The built in browser I was not to fond of, mainly because of how bookmarks were laid out, it took like 2 or 3 clicks to get to them, then they were tiles. I was recommended to get dolphin browsers which was great and would have served as the replacement until it stopped working(not compatible yet)
7. When you sign into google while setting the phone up...It takes every google account you set up ever and puts it on the phone...I ended up going to my photo gallery and saw my 30gb of pictures i uploaded to picasa! pretty cool!
8. The camera is slightly better than the iphone 4 i would say, the SLR type shooting pictures speed is nice but most come out blurry. The shutter speed is just to fast, but when you take just one pic like we do with our iphones is great and then gives you multiple options to upload it to many many photo sites/social networks.
9. Google music works great on it, takes maybe 2-3 seconds to load an album for the first time, after that it was instant every time i went to it.
10.Visual voicemail...I was worried about this not having it, but I went to the app store and Verizon had an app for it...Its basically a seperate icon on your screen wherever you put it and you click on that for your voicemails, it is not built into the dialer, I actually preferred it this way after using the phone for awhile
