How does STAMINA mode work?
Battery life is one of the aspects of smartphone design that still requires significant improvement. One way to facilitate this will be through hardware technology breakthroughs, one of which we recently covered here. The other approach to improving battery life, however, is by optimising the software used on handsets. With handsets such as the Xperia Z, Sony has tried to do just that with STAMINA mode.
An easy assumption to make when it comes to smartphone battery life is that placing your handset on standby will stop apps from running and therefore stop power consumption. This is incorrect – apps still run in the background and there are constant synchronisation requests for things such as message updates and notifications.
Using STAMINA mode, Sony does its best to address the problem of apps running in the background. It achieves this by blocking data traffic a minute after the handset is placed on standby. Whilst doing this the phone automatically logs your IP address, meaning you are instantly connected once the phone is powered on again.
When STAMINA mode is activated, you will still receive phone calls, text messages and picture messages. However, you should be aware that notifications that require an internet connection will stop.
