Why Is My iPhone 7 Battery Draining So Quickly?
Most times, the problem is either hardware-related or software-related.
When it’s hardware-related, it means your iPhone 7 battery may be close to the end of its battery life. Usually, it is the natural aging. However, if your device suffered from physical damage, you need to replace a new battery.
On the other hand, several bugs within your iOS might be responsible for your iPhone 7 battery draining so quickly, such as the malfunctioning apps, faulty settings and more.
Luckily, if your iPhone 7 has no physical damage, then this battery draining fast issue is certainly caused by software bugs. And it can be fixed with the methods in this article!
15 Tips to Fix iPhone 7 Battery Draining Fast All of a Sudden
Note: information in this article apply to iPhone 7 and iPhone 7 Plus
1. Try Restarting to fix iPhone 7 battery drain issue
Restarting your device is troubleshooting 101. If you ever have any issue with a device, Apple-made or otherwise, a simple restart almost always helps. Restarting your iPhone probably won’t fix the problem of battery drain completely, but it’s likely to give it a bit of a boost.
- Hold down the power button until Slide to Power Off appears on the screen.
- Slide the slider to power off the iPhone.
- Wait a minute, then hold the power button again until the Apple logo appears, and release.
2. Enable Low Power Mode on iPhone 7
Low Power Mode is super handy for extending the life of your iPhone 7 battery when you’ve overdone it a little. It does this by nerfing your iPhone 7 in certain ways, disabling or restricting features including 5G, visual effects, refresh rate and screen brightness. It’ll buy you some precious time to get to an outlet, though.
activate Siri and say, “Turn on Low Power mode.”
Alternatively:
- Open Settings, then tap Battery.
- Toggle Low Power Mode to on.
3. Enable Auto-Brightness on iPhone 7
iOS is often the best judge about when your iPhone 7 should be doing certain things. We often like to think we know better, and I’m guilty of turning this feature off regularly, preferring to control brightness myself. However, the fact remains that if you want the best balance of usability and battery life, you should be using Auto-Brightness, which adjusts your iPhone 7 screen’s brightness based on surrounding lighting conditions.
- Open Settings, then tap Accessibility.
- Select Display & Text Size, then scroll down and toggle Auto-Brightness to on.
4. enable Reduce Motion on iPhone 7
When you open apps, you may have noticed there’s a swooshing animation as the tile turns into the app, this is a motion effect. Similarly, as you move your iPhone 7 about, you may notice the tiles and icons moving slightly relative to your wallpaper, which is called a parallax effect. Both of these consume battery and can be turned off (incidentally, this is something that Low Power Mode does for you).
- Open Settings, then tap Accessibility.
- Select Motion, then toggle Reduce Motion to on.
5. Turn Off Raise to Wake on Your iPhone 7
iPhone 7 has the Raise to Wake function enabled by default. This might be part of your problem, especially if you pick up your iPhone a lot or walk with it swinging in your hand. The iPhone screen constantly turning on will definitely drain your battery. To turn off Raise to Wake to save iPhone battery life:
- Open the Settings app, then tap Display & Brightness.
- Scroll down to Raise to Wake and toggle it off. A gray toggle means Raise to Wake is disabled.
6. disable Background App Refresh on iPhone 7
When you’re connected to the internet, the apps on your phone will refresh their content in the background. This is a useful background task, but can drain your iPhone 7 battery slightly, so it’s worth turning it off. Again, this feature is also disabled in Low Power mode.
- Go to Settings, then tap General.
- Select Background App Refresh, then tap Background App Refresh.
- Tap Off.
- Alternatively, on the Background App Refresh Page, toggle the setting off for individual apps.
7. Limit Location Services on iPhone 7
Every time your phone is using GPS, it’s using power. You could turn off Location Services altogether, but some apps need this to perform their intended function, like Google Maps, meaning you’d have to turn GPS back on again every time you used them. It’s better to limit your apps to using Location Services only while you’re using them, or when they’ve asked to do so.
- Go to Settings, then tap Privacy.
- Select Location Services.
- Select each app individually and tap While Using the App.
- Alternatively, tap Ask Next Time Or When I Share.
8. Disable Wi-Fi, Bluetooth and AirDrop on iPhone 7
Wi-Fi, Bluetooth and AirDrop all consume power when in use. Even if you’re not using your iPhone 7, it may be scouring its surroundings for Wi-Fi networks, or looking for other devices via Bluetooth and AirDrop. Turn Wi-Fi and Bluetooth off to disable the lot (as AirDrop uses Bluetooth to find other devices).
- From your Home Screen, swipe up from the bottom to open Control Center.
- Tap the Wi-Fi and Bluetooth icons to disable them.
- Alternatively, open Settings, select Wi-Fi and/or Bluetooth and tap the respective toggle to off.
9. Update iOS on iPhone 7
Your iPhone 7 operating system, iOS, is the master at managing your phone. It’s constantly being refined and updated by Apple, and this will include things like performance and power enhancements. Keep it up to date.
- Open Settings, then tap General.
- Select Software Update, then tap download and Install if an update is ready.
- Tap Automatic Updates and make sure both toggles are set to on.
10. How to fix battery drain on iPhone 7: stop closing apps
It’s a long established fact that swiping apps closed from multitasking view does nothing to save battery life. These apps run in a suspended state after you stop using them and do not impact performance or battery life. In fact, it actually takes more energy to restart some apps after closing them than it does to just leave them suspended. So, if you’re a serial closer downer, especially of apps you use frequently, stop closing them.
There is a caveat to this, however. Some apps do run in the background, using battery. You can check whether an app is doing this in the Battery menu.
- Open Settings, then tap Battery.
- Scroll down to the Battery Usage by App section.
- If any apps have “Background Activity” underneath their name, they’ve been running in the background. You will see the percentage of your total power usage the app has consumed on the right. This is common for apps like VPNs, which run in the background while you’re doing other things.
- Tap Show Activity. Underneath the app’s name, you’ll now see how much of the total time the app was consuming power took place while the app was on screen (i.e. while you were using it), and how much took place in the background. Follow step 6 to prevent Background App Refresh taking place and save battery, but bear in mind that for apps like VPNs, which are using battery in the background as part of their normal operation, this won’t do much (as they aren’t using battery primarily through background refreshing). In these cases, you’ll need to uninstall the app.
If you see “Audio” underneath the app, with background time showing when you check activity, you don’t have to worry. This is normal for apps like Spotify or Apple Music, which technically use power in the ‘background’ while playing. It’s not really in the background though, as you’re listening to their output — and this is exactly what you want them to do anyway. Apps like YouTube will also show “Audio” and background activity when you’ve been casting to another device, like a TV, as technically this is not screen time.
11. Use Airplane Mode or Wi-Fi to Stop iPhone 7 Battery Drain
If a secure Wi-Fi network is available, log into it rather than using your cellular data plan. Also, if you are out and about in a location with poor cellular reception, having your iPhone constantly searching for a cell signal leads to your iPhone 7 battery draining faster than you may realize. To prevent iPhone 7 battery drain, open the Control Center by swiping up from the bottom of the screen instead. Next tap on the Airplane mode icon which, logically enough, looks like an airplane. When the icon is orange, Airplane mode is enabled, and your iPhone will not continue searching for a Wi-Fi or cellular signal.
12. Stop Sharing iPhone Analytics
The first time you set up your iPhone, you may have agreed to share data analytics with Apple. It’s normal since you’re a first-time user—Apple probably knows better. You should know that when you Share iPhone Analytics is activated, it shares useful diagnostic information with Apple, which aids them in improving their products and services. Since Share iPhone Analytics consistently runs in the background, your iPhone 7 battery drains fast.
To turn off this feature:
- go to Settings, then tap Privacy.
- Select Analytics, then turn off the switch next to Share iPhone Analytics.
13. Delete Unnecessary Widgets on iPhone 7
Widgets are fast and easy shortcuts to get information on specific things without having to open an app. However, it can drain your iPhone 7 battery just as fast because a widget needs to update its data constantly. To fix this, you need to remove all or some of the widgets, especially if you know you don’t need them.
- Open the Today View by swiping right on the Lock screen or swiping all the way right on your Home screen, one screen past the first Home screen page.
- Scroll to the bottom and tap Edit.
- If you started from the Lock screen, you’ll need to unlock your phone to make changes.
- Tap the Remove icon next to any widgets you’d like to remove.
- For widgets on your Home screen pages, long press the screen until it enters Jiggle mode.
- Tap the Remove icon on widgets you’d like to remove.
- Tap Done in the upper-right corner when you’re finished removing widgets.
14. Update all Apps on iPhone 7
App updates provide users with the latest improvements, which may improve the iPhone 7 battery life and performance. If your iPhone 7 battery drains fast, you should consider updating all your apps. To do this:
- Go to the App Store, then tap your profile at the top of the screen.
- Undr available updates, tap update all.
15. Reset All Settings on iPhone 7
As stated earlier, your iPhone 7 settings to some extent determine the strength of your iPhone’s battery life. Some users pointed out that resetting all settings can fix the issue of the iPhone 7 battery draining fast all of a sudden. Bear in mind that this reset procedure will not affect any data you’ve saved on your device. Ethere’ll be no permanent loss of data). It’s only your customized settings that will change.
It would be best if you give this a try.
- Go to Settings, then tap General
- Select Transfer or Reset iPhone, then tap Reset.
- Tap Reset All Settings.
Your iPhone will automatically reset all settings, before rebooting. Wait till it boots up, then try to use your device normally to see if the battery will still drain quickly.
There you have it. You’re now equipped with an arsenal of tips to fix iPhone 7 battery drain issue.
