My phone battery last up to 2 days, my tips is you should disable or uninstall some of the apps you didn't use. Download greenify and its donation package, this app can forcely closed the apps and some of the system apps like gmail, exchange service etc.. Hope it will help ypu a lot.

try to stop all unused apps, don't let wifi or 4G always running, it depends usually on your usage.

I think it totally depends on your usage. Try disabling/freezing apps that you don't use. Minimize the brightness, disable Wi-Fi and network data to save more battery.

I am also facing the same issue. I replaced my honor 3X with the honor 4X and I am starting to feel I made a big mistake. Battery life on the 3X was excellent. Any suggestions would be greatly appreciated. Thanks.
