Battery life is a constant worry for smartphone owners. Even those of us with phones that last for days, like the Sony Xperia Z5, wish we didn’t have to plug in quite so often. But with Doze being introduced in Google’s recent Android Marshmallow update, a lot of our battery woes have been solved.
What is Doze?
Doze is a new battery-saving mode designed to work when you’re not using your phone. And when we say ‘not using your phone’ we mean ‘when you’ve left your phone on the bedside table or desk’ – even the motion of the phone in your pocket will stop Doze kicking in.
Doze isn’t always on because it shuts down almost everything on your phone. By default, the only thing left running is your antennae so you can get calls and texts. Every now and again, Doze wakes your phone for a quick download from all your apps, but most of the time things are in a deep sleep.
If you have the odd app that you really need notifications from (work email, maybe?) you can set them as priority so Doze doesn’t switch them off. Of course, the more things you set as priority, the worse your battery life will be.
How do I use Doze?
That’s the beauty of Doze – when your phone updates to Android Marshmallow you won’t have to do anything to start using it. Whenever your phone’s inactive, Doze will automatically kick in. The only thing you might want to do is set up those priority apps, which you can do in a few simple steps:
- Open Settings
- Tap Battery
- Tap the three dots in the top right
- Tap Battery optimization
- Tap the dropdown menu and select All apps
- Tap any apps you always want to get notifications for and tap Don’t optimize
Does Doze really work?
Yes, it does. We updated a Nexus 5 to Android Marshmallow to test Doze and the results were truly amazing.
Running its original Android KitKat software, and then Android Lollipop, the Nexus 5 could barely make 100% battery last a working day. That’s not good considering it wasn’t a work phone so was left on the desk until we wanted to sneakily check Facebook or organise the post-work night out.
With Android Marshmallow and Doze, we were able to leave the office with 77% battery left – about 70% more than before the update.
If you’re using a Nexus device at the moment, Doze on Android Marshmallow will make a big difference to your battery. But we’ll have to wait and see how effective it is on other phones as manufacturers tend to add their own battery-saving software to Android.
