Battery life is great for me. Especially compared to my Nexus 5. I start my day with 90% at 7:30am and still have 15-19% battery life by 10pm. Maybe just some Nexus 6's suffer from poor battery life. But that's just my take. (poopy)
It is the most amazing place on Earth. Full of real life miracles and apparitions by Our Blessed Mother and Jesus Himself!!! But please, go with an open heart. **DO NOT GO TO TEST GOD** Be patient and child-like at heart. You WILL see miracles, but at His time and pace. Guaranteed. God is real, and He will make his presence known to you here no doubt.
