Fix iPhone Battery Drain on iOS 10: 10 Practical Tips

If your iPhone loses charge quickly on iOS 10, the cause may be a busy app, weak signal, bright display, or an aging battery. These ten checks help reduce avoidable power use and identify when a setting change is not enough. Before you begin, charge the phone, note how quickly the battery is falling, and make sure you can access Settings.

What You’ll Need

• Your iPhone and its passcode.
• A charger and cable for charging before or during checks.
• Wi-Fi access if you plan to update iOS or apps.
• About 15–30 minutes to review settings; some changes need a day of normal use to assess.

Step-by-Step

1. Check battery usage. Open Settings > Battery and review the battery usage list. Tap the clock icon if available to compare activity over the last 24 hours or several days. Look for an app using a large share of power, especially one you have not actively used. A high percentage alone is not proof of a fault: an app used for a long time can naturally account for much of the total.
2. Update apps that are draining power. Open the App Store, tap Updates, and update apps with available fixes. If one app repeatedly appears near the top despite little use, check its settings for background activity or location access. You can also delete and reinstall it if you know your sign-in details and its data is backed up or synced.
3. Limit Background App Refresh. Go to Settings > General > Background App Refresh. Turn it off for apps that do not need to refresh when you are not using them, or choose Wi-Fi instead of Wi-Fi & Cellular Data if that choice appears. Leave it enabled for apps where timely background updates matter to you. This setting does not stop notifications.
4. Review Location Services. Open Settings > Privacy > Location Services. Check apps with frequent location access and select While Using the App where that option is available and suits the app. Turn location access off for apps that do not need it. Some iOS 10 apps may offer different choices, so use the options shown on your phone.
5. Reduce display power use. Lower brightness in Settings > Display & Brightness or in Control Center, and enable Auto-Brightness if available in Settings > General > Accessibility > Display Accommodations. Set Auto-Lock to a shorter interval under Display & Brightness. A screen that stays bright and on for long periods can use substantial power.
6. Use Low Power Mode when needed. Go to Settings > Battery and switch on Low Power Mode. It reduces or pauses some background tasks and visual effects to extend use between charges. Some mail fetch, downloads, and background updates may be delayed. Turn it off when you no longer need the extra conservation.
7. Improve cellular signal conditions. Searching for a weak signal can increase power use. If reception is poor, move to a location with better coverage or use Wi-Fi for internet calls and data where available. If you do not need cellular service temporarily, use Airplane Mode from Settings or Control Center; remember that it disables cellular connections until you turn them back on.
8. Choose fetch settings that suit you. Open Settings > Mail > Accounts > Fetch New Data. If Push is enabled and you can accept less frequent updates, turn Push off and choose a longer fetch interval. Where available, set accounts to Manual. This can delay new messages, so keep a faster setting if immediate email matters.
9. Restart the iPhone and install available updates. Restarting can clear a temporary software problem. Then check Settings > General > Software Update and install an update offered for your device after backing up and connecting to power and Wi-Fi. iPhone 10 refers to the model name commonly used for iPhone X; it shipped with iOS 11, not iOS 10. If your phone is actually an older model running iOS 10, only install updates offered as compatible with that model.
10. Check battery condition and reassess. On iOS 10, there is no Battery Health screen like later iOS versions. If the phone shuts down unexpectedly, loses charge rapidly even with light use, or has a battery that may be swollen or damaged, stop using it if it appears unsafe and seek qualified service. After changing settings, compare battery use over a normal day rather than judging from a short test.

Common Mistakes

• Force-closing every app: Repeatedly swiping apps away is not a reliable battery fix. Close an app if it is unresponsive; otherwise, focus on its background, location, or usage settings.
• Turning off everything: Disabling all location, mail, and background functions can disrupt services without solving a worn-battery problem. Change only settings that fit your needs.
• Expecting instant results: Battery percentages fluctuate, and recent charging or heavy use affects them. Compare similar periods of ordinary use.
• Confusing model and software: iPhone X did not run iOS 10. Check Settings > General > About for the model and software version before following version-specific instructions.

Tips

• Use Wi-Fi when it is reliable; it can use less power than a weak cellular connection.
• Keep the phone and apps current with versions compatible with your device, and back up before major updates.
• Use a shorter Auto-Lock time and avoid leaving navigation, video, or games running when you are finished.
• Check the Battery screen again after a day or two to see whether the change helped.

Troubleshooting

Battery still drops quickly? Restart, then check Settings > Battery for an app that remains unusually active. Update or remove that app temporarily and compare usage. If the drain began after an update, allow time for any setup or syncing to finish, then reassess; do not assume the update itself is the only cause.

The phone gets hot or shuts down? Stop demanding tasks, move it out of direct heat, and let it cool naturally. Do not put it in a refrigerator or use other rapid-cooling methods. Repeated unexpected shutdowns or severe drain warrant a battery inspection by a qualified service provider.

A setting is missing? Menu names and options vary by iOS version, model, and account. Confirm your version in Settings > General > About, then use Settings search if available or look for the closest named option. Do not install an update that is not offered for your model.

Still no improvement? Back up the iPhone before considering a settings reset or restore. A restore can erase data, so use it only after verifying the backup and account access; contact qualified support if the battery may be physically damaged.

Frequently Asked Questions

Does Low Power Mode damage the battery?
No. It temporarily reduces some activity to conserve charge; it does not repair or damage the battery.

Should I close all apps to save power?
No. Force-closing apps routinely is generally unnecessary. Address apps that show persistent, unusual activity in Battery settings.

Why does my iPhone lose charge overnight?
Background activity, poor cellular reception, notifications, or battery wear may contribute. Check Battery usage and try a night in a location with good signal; Airplane Mode can help identify whether cellular searching is involved, but disables calls and cellular data.

Can I check battery health on iOS 10?
iOS 10 does not include the Battery Health menu found in later versions. For rapid drain, shutdowns, or suspected damage, ask a qualified service provider to inspect it.

Will updating iOS always fix battery drain?
No. Updates can address software issues, but drain can also result from app activity, weak signal, settings, or an aging battery. Install only updates compatible with your device.

Does iPhone X run iOS 10?
No. iPhone X launched with iOS 11. If your device runs iOS 10, verify its model in Settings > General > About and follow instructions for that model.
