I stopped listening to how awesome they claim their new battery life is a long time ago. Once again same old POS. I had 100% and in less than 4hrs it was dead just installing apps and transferring pics etc....
The best I have got so far.. 4 full days after 100% charge. On ios9, display brightness set to Auto, turned on Low Power Mode when the battery reached to 11%. Wi-fi and Bluetooth on all the time.
