There’s a lot you can do to make the battery in your Windows Phone last longer between charges. The easiest way is to use Battery Saver. You can set it so that it’ll turn on any time your battery gets too low, or if you know in advance that you’re going to need to make every bit count, you can turn it on to make sure your battery lasts as long as possible.
When you turn on Battery Saver, your phone automatically turns off some of the features on your phone that use battery in the background. So when Battery Saver is on, your phone will no longer:
• Automatically receive email or calendar updates – You can still sync your email manually whenever you want.
• Update some Live Tiles – The technical explanation is that if a Tile uses something called push notification to get its updates, it’ll stop receiving those updates in Battery Saver mode. But the upshot is that when Battery Saver is on, some of your Tiles won’t be updated.
• Allow apps to run in the background – You’ll only be able to use an app if it’s open.
To turn on Battery Saver
- On Start, flick left to the App list, tap Settings Settings icon, and then tap Battery saver.
- Do one or both of the following:
- If you want Battery Saver to turn on whenever the battery gets to 20%, select Always turn on Battery Saver when battery is low.
- If you want to turn on Battery Saver now and leave it on until the next time you plug in your phone, select Turn on Battery Saver now until next charge.
