I got this mobile at 3 Feb. Fully charged battery from 0% to 100% it took time exactly 1 hour 45 min. I Used it for few min and slept. Next day morning when I wack up the battery level is still 100%. I am surprised!. I used the mobile for another 30 min still it is 100%.
Battery assistant is in Ultra-long stand by mode. I think it does all this wonders. Extraordinary battery! Don’t believe on the negative comments about the battery. Heating during charging is all about wrong review. Regarding fast charging, my phone got charged 65% in 60 minutes and I felt WOW. and no any heat.
After 3 hours of average usage with WI-fi(whats app, app download, a bit browsing and idle for around 2 hour) battery went down to 99%. To my way of usage I start to believe that this mobile will last for 2 days. Extremely good battery. Note: Mobile is in Ultra-long stand by mode. We need to enable wi-fi manually in this mode.
