Mobile devices like iPhones and iPads are central to the lives of many of us these days, and battery life is always at a premium. It's not helpful, then, when something does wrong with the battery on your iPhone or iPad. Maybe it's draining faster than it should, or perhaps you've run into a problem with random shutdowns. Whatever the case may be, there are several options for confronting your battery woes depending on your particular situation. And with iOS 11.3, you can now exercise more control over how your iPhone handles saving power versus performance, and get a better picture of your device's over battery health.

What do you do? Here's everything you need to know about fixing battery problems on your iPhone or iPad.

What's new with iPhone and iPad battery life?

With the release of iOS 11.3, Apple added features to the iPhone to help you monitor and manage the health of your device's battery. The new Battery Health (Beta) section under Settings > Battery will show you the overall health of your iPhone's battery and will tell you whether or not your iPhone is currently under performance managment, which slows down the performance of your device in exchange for longer battery life.

How to see what's using battery life on your iPhone or iPad

If your iPhone, iPod touch, or iPad is losing battery life faster than normal, it could be the result of an app or service using more power than it ought to be. Thanks to "battery shaming," you no longer have to wonder about which app or service it might be, or try to quit them all just to stop the drain. Now you can see exactly what's using your battery life and how.

Have you had an iPhone, iPad, or MacBook for a few years and feel like your battery doesn't hold the same amount of juice as it used to? That's because it doesn't. The lithium-ion batteries that power your devices deteriorate over time, meaning the battery can't charge to its full capacity.

iPhones are typically rated for 10 to 12-hours of battery life. That includes the new iPhone X, iPhone 8, or iPhone 8 Plus, or the still-for-sale iPhone 7 and iPhone 7 Plus, iPhone 6s or iPhone 6s Plus, or iPhone SE. If you've updated to iOS 11.3, or you're upgrading to a new iPhone, you might see a serious drain on your battery life. Here's what to do about it!

How to fix iPad and iPad Pro battery life problems

Apple currently offers the second-generation 12.9-inch iPad Pro, a 10.5-inch iPad Pro, a new lower-cost 9.7-inch iPad, and the smaller 7.9-inch iPad mini 4. Like every iPad before them, they're rated for 10 hours of battery life while browsing the web, checking email, and chatting. But if you've just set up a new one, especially if you restored it from a previous device backup or you've just installed iOS 11, you might see more drain on your battery than you'd otherwise expect.

How to improve your battery life with Low Power Mode

Battery Settings are now top level on iPhone and iPad. That includes toggling on percentage display and seeing what's gobbling up your power on iPhone and iPad. It also includes a manual switch for Low Power mode on iPhone. If you have one of the iPhones 6s or Siri, you can even access power settings faster than ever!

How to prevent random shutdowns on your iPhone or iPad

Sometimes good batteries go bad. In a few cases, there can be actual problems with the battery chemistry. In others, leaving phones on heating vents or otherwise "burning" them out has drastically reduced the usable life.
