Apple’s been in the courtroom for several years now, after the company was found to be slowing down older iPhones without the consent of the owners. The company’s reasoning? The health of the batteries inside those iPhones had degraded to a point where running at full speed could trigger shutdowns or other issues.

That series of lawsuits has also led to Apple adding a very useful tool into its products, including the Battery Health feature.

The feature lets you see how well your battery is faring under your usage, and also tells you if you can do things to improve the battery’s health, or if you need to replace it. That same tool is also coming to the Apple Watch, and macOS is getting some new stats pages for a more complete picture of your battery use, as well.

Here’s how to check the battery health of your iPhone, iPad, Apple Watch, and MacBook

Detailed stats and health information for your MacBook's battery! -AWARDED MACWORLD 'MAC GEM' - The Best Battery Health App With Battery Health, you can easily see all the important information about your MacBook's battery, such as current charge level, battery capacity, power usage, number of times it has been charged and much more. That’s where Low Battery Saver (Mac App Store link) comes in. The app’s purpose in life is solitary: It warns you when your battery hits a certain amount of time remaining, and then shuts down. Your Mac tracks the “energy impact” of each running application in a few places. Like on an iPhone or iPad, you can see exactly which apps are using the most power, and adjust your usage accordingly so you don’t run out of juice. Applications aren’t the only thing draining battery power, of course. Pretty cool app This is a cool app to test the power that your cell phone battery is putting out. I just replaced my battery and wanted to check to see if it was in fact a brand new and powerful battery and this app give me a good high score, in the low 900’s so I'm a happy camper. Thanks to the developers of this app.

It’s pretty simple to check the new inbuilt tools that Apple added, so you can keep an eye on your not-user-replaceable battery.

iPhone or iPad:

  1. Open the Settings app
  2. Scroll down to Battery and tap
  3. Tap on Battery Health
  4. You’ll see percentages detailing your battery’s health, plus suggestions if your battery is less than optimal Image: KnowTechie

This last screen will also tell you if your battery has degraded to the level of needing a replacement. Just know that’ll cost around $80 if so.

Apple Watch:

You’ll need to be updated to WatchOS 7 to be able to check the battery health on your Apple Watch. So, until the public beta arrives, you’ll need to be using a developer account to access this currently. If you are, here’s how to check:

  1. Open the Settings app
  2. Scroll down until you see Battery, then tap on it
  3. Tap Battery Health

That’s it, you’ll now see a percentage indicating how healthy your battery is, and any advice you may need on how to improve it.

MacBook:

Apple added a Battery Health feature to macOS back in April, but macOS Big Sur (the next major update) brings even more battery tools. You’ll be able to see exactly which apps are draining your battery, both as a daily rundown or over the last ten days.

  1. Open System Preferences from the Apple logo at the top left of your screen
  2. Click on Battery

You’ll now see graphs of your Mac’s energy usage on the Usage History tab, along with a graph of Screen On Time, so you can match the two together. You can also check the battery health of your MacBook by going to System Preferences > Power Saver > Battery Health.

That’ll give you the health status, and an option about disabling Battery Health Management, which automatically adjusts performance and the maximum charge of your MacBook’s battery depending on your usage habits. It’s pretty much the same system that’s in iOS, so it will be interesting to see how well it works when it hits my work laptop in the fall.

Optimized battery charging

Image: KnowTechie

While you were checking out your battery health on your iPhone, you probably saw a toggle for Optimized Battery Charging. This handy setting learns your charging routine, then instead of fully charging your device, it’ll charge to 80% until before you usually pick it off the charger, when it will finish charging to 100%. That puts less strain on your battery over time, hopefully resulting in a longer lifespan for your device.

Oh, and while we have you. If you had an iPhone 6, 6 Plus, 6S, or SE, or an iPhone 7 or 7 Plus that experienced slowdowns, go join the class action so you get some cash for your troubles.

Editors’ Recommendations:

TestFlight makes it easy to invite users to test your apps and app clip experiences and collect valuable feedback before releasing your apps on the App Store. You can invite up to 10,000 testers using just their email address or by sharing a public link.

Overview

To take advantage of TestFlight, you’ll need to upload at least one beta build of your app to App Store Connect, and invite testers using their email addresses or by sharing a public link. Testers can get started by accepting your email invitation or following the public link. To install your app and provide feedback, testers will use the TestFlight app for iPhone, iPad, iPod touch, Apple Watch, and Apple TV. Testers can turn on automatic updates in the TestFlight app to ensure they’re always testing the latest available build.

Internal Testers

Add up to 100 members of your team who have been assigned the Account Holder, Admin, App Manager, Developer, or Marketing role to quickly test beta builds as you iterate on your app. Each member can test on up to 30 devices. Internal testers can access all of your beta builds available for testing.

External Testers and Groups

Mac

Invite up to 10,000 external testers using their email address or by enabling and sharing a public link, which creates an open invitation for anyone to test your app. Simply create a group of testers and add the builds you’d like them to test. You can also create multiple groups and add different builds to each one, depending on which features you want them to focus on. When you add the first build of your app to a group, the build gets sent to beta app review to make sure it follows the App Store Review Guidelines. Testing can begin once your build is approved.

Using Email to Invite Testers

If you know a tester’s email address, you can email an invitation with a link to install your app and start testing. If you have an existing set of external testers or specific people you’d like to invite to test, email can be an effective way to share beta versions of your app.

Using Public Links to Invite Testers

Public links let you share your app with people outside your development team without email or other contact information. You can share your public link on social media, messaging platforms, email campaigns, and more to expand the visibility of your beta test. If you don’t have an established group of external testers, using public links can be an effective way to increase your app’s reach and grow your test audience.

To enable a public link, go to your app’s TestFlight page, click an existing group, and click Enable Public Link. You can then copy the link and share it outside your organization. When you share your public link, many social media platforms will display your app icon, name, and supported device. To help give potential testers additional context, consider including details about your app and TestFlight. Remember not to localize the name TestFlight or create custom badges to promote your app on TestFlight.

If you’d like, you can limit the number of testers that can use the public link to join the group. Depending on your team’s resources, you may want to start small and increase the limit over time. If the group limit is reached or if you disable your public link, anyone trying to become a tester will see a message that your beta is full or no longer accepting new testers. To ensure a good user experience for potential testers, be thoughtful about where you share your public link and when it may be appropriate to remove your public link.

Test Information

When sharing your app with external testers, you’ll need to let them know what to test and any other important information relevant to testing. Enter these details in your app’s Test Information page in App Store Connect. You should also provide an email address that you monitor so you can receive and respond to feedback that testers provide. Test information is optional when distributing your app to internal testers.

Getting Feedback

With TestFlight 2.3 or later on iOS 13 or later, testers can send feedback directly from your app simply by taking a screenshot. They can also provide additional context about an app crash immediately after it occurs. To view this feedback, go to your app’s TestFlight page in App Store Connect, and click Crashes or Screenshots in the Feedback section. Feedback from testers on tvOS or earlier versions of iOS will be sent to the email address you provide in Test Information.

Supported Apps

TestFlight supports apps for iOS, watchOS, tvOS, and iMessage. Up to 100 apps can be tested at a time, internally or externally, and multiple builds can be tested simultaneously. Builds remain active for 90 days after upload.

Battery Tester App Windows

TestFlight App

When testers are invited to beta test your app, they are prompted to install the TestFlight app from the App Store on their iPhone, iPad, iPod touch, or Apple TV if they don’t already have it installed. The TestFlight app makes installing betas simple, and you don’t need to keep track of UDIDs or provisioning profiles.
