Verizon Gnex with stock OS, battery doesn't do very well on battery as it is now. I hope upcoming OS update will improve it for non-rooting stock users. But there are some helpful battery tips that were discussed on other threads a lot. The biggest saver is to turn LTE off if not needed. For occasional email, text checking, browsing facebook, 3G/CDMA is just fine. Using WiFi when available makes big difference too. Also avoid SNS apps like Google+, facebook and use stock browser for those. Always be careful when installing apps using auto sync. This way it should last full day.
I think I might be getting the hang of it. I managed to get mine to last 16 and a half hours yesterday. With only maybe a 3 minute boost charge.
It still drains like mad crazy if your doing pretty demanding tasks especially over 3G with pretty mediocre reception.
