Why is this always so low before the battery dies? I know there is no comparable stat in iOS but it's obvious to me that the battery on my 6S+ lasts way longer than my Xperia XZ. I can browse the web for 11+ hours before my iPhone dies but with the XZ it's around 6 hours tops. Yeah the battery is smaller but even a regular 4.7" iPhone can slay my Android when it comes to web-related battery drain. My Samsung tablet has poor battery life too, is this an Android thing?
