One of the things that people clamor for with each new generation of smartphones is longer runtime. That can be accomplished with larger batteries and more power miserly hardware. With the new Android devices from Sony on the market, the Xperia Z3 and the Z3 Compact, record setting battery life is here for Android devices.
The Xperia Z3 Compact smartphone has a 2600 mAh internal battery and in battery testing it lasted 10 hours and 2 minutes when Phone Arena put the smartphone through its paces. That ten-hour runtime put it at the top of the stack for non-phablet smartphones.
Its larger brother the Xperia Z3 also racked up a record setting score in battery life for large screen phablet phones. The full-size Z3 put down a battery life of 9 hours and 29 minutes putting it ahead of the competition like the Ascend Mate 7 and the Xperia Z2. That score is nearly three hours longer than the iPhone 6 Plus.
The battery test Phone Arena uses a script that replicates non-stop usage of a smartphone along the lines of what a person would do in real life with no idle time. In a real world situation, the Z3 and Z3 compact would be able to last about two days with some idle time mixed in.
