The battery lasted well over a day with heavy use, but it does run a little hot when on a charge

Battery works all day

The battery also gets significantly hot with heavy usage which happens to be my biggest gripe about this device, but that's easily fixed by putting on the included zebra patterned silicone case it comes with so you don't have to feel it as much

The battery dies extremely fast and I am a moderate user

The battery is absolutely horrible and does not have a charge at all

It lacks battery saver mode like my Samsung.

The battery runs a little hot, but not overly so

I was pleasantly surprised by the good battery life
