  • Hi Atish,
    Saving my smartphone battery was a headache for me as I have to travel a lot sometimes and there are times when its hard to find a place where I can charge my cellphone. I previously used battery doctor app and later switched to the DU battery saver. Both works fine but the DU PRO needs to add some more apps that’s the only thing that annoyed me. So I switched to a portable wireless charger and bought a power bank for this.
