I notice you keep asking about battery
I can tell you battery life is just insanely good
It is the best I have ever encountered in all the androids I have used
It is at least 2-3 times better than note/s3 n 4x that of s2
It can easily last 4+ days on 3g actively on 24/7 with active background notification, gmail, mail, tweeter updates
Most users say 1-2 hours browsing, 1-2 hours video plus call sms n email tweets etc 14-18 hours. Light users 2 days
Gsmarena did a comparison tests n I fully agree with those numbers

One can always get a spare battery if really heavy user
Should not n never an issue at all to affect buying decision
