Charging your phone affects the screen

Extend battery life and service life

"Battery life" is the amount of time your device will run before it needs to be recharged. "Battery life" is the amount of time you can use the battery before it needs to be replaced. If you renew both, you can get the most out of your Apple devices - no matter which device you have.

General tips on performance

Update to the latest software.

Updates to Apple software often include improved energy-saving features. So always make sure that the latest iOS, macOS or watchOS version is installed on your device.

Avoid extreme ambient temperatures.

Your device is designed to work well over a wide range of temperatures. The ideal range is between 16 ° C and 22 ° C. In any case, you should try to avoid ambient temperatures of over 35 ° C for your device, as this can permanently impair the capacity of the battery. This means that the battery can no longer supply the device with power for as long on one charge. Charging in high ambient temperatures can damage them even further. The software may prevent charging above 80% if the recommended battery temperature is exceeded. Even storage at too high ambient temperatures can permanently damage the battery. If you expose your device to very cold ambient temperatures, the battery life may be temporarily reduced. When the temperature of the battery returns to normal operating temperature, performance will also normalize.

Ideal area for iPhone, iPad, iPod and Apple Watch
Too cold room temperature Too hot

iPhone, iPad, iPod, and Apple Watch work best in ambient temperatures between 0 ° C and 35 ° C. Storage temperature: -20 ° C to 45 ° C.

Ideal area for MacBook
Too cold room temperature Too hot

The MacBook works best in an ambient temperature between 10 ° C and 35 ° C. Storage temperature: -20 ° C to 45 ° C.

Remove bags and covers when loading.

If you charge your device while it is in certain cases, it can overheat. This can affect the battery capacity. If the device gets very hot while charging, take it out of the case. For Apple Watch Edition models, make sure the cover of the magnetic charging case is open.

Store the device half-charged if it is to be stored for a long time.

If you want to store your device for longer, two factors influence your battery: the ambient temperature and the battery charge before the device is switched off for storage. We therefore recommend the following:

  • Do not fully charge or discharge your device's battery, but rather to approximately 50% of its capacity. If the device is stored with a completely discharged battery, the state of discharge can drop so far that the battery can no longer accept a charge. Conversely, long-term storage with a fully charged battery can lead to partial loss of battery capacity and thus to a shortened battery life.
  • Turn off the device to avoid further discharging the battery.
  • Store the device at a temperature below 32 ° C in a cool, dry place.
  • If you plan to store the device for more than six months, charge it to 50% every six months.

Depending on how long it has been stored, your device may have a low battery capacity when restarted after a long period of storage. After long periods of storage, it may need to be charged with the original adapter for 20 minutes before use.

Tips for iPhone, iPad and iPod touch

Update to the latest software.

Always make sure that you have the latest version of iOS installed on your device.

  • If the device has iOS 5 or later installed, check whether an update is necessary. Go to Settings> General> Software Update.
  • When an update is available, you can plug in your device and update it wirelessly, or plug it into your computer and update it with the latest version of iTunes.

Optimize settings.

There are two simple ways to extend the battery life, no matter how you use the device: Adjust the brightness of the display and use WiFi.

The battery life can be extended by dimming the display or activating the "Auto-Brightness" option.

  • To dim it, open the control center and drag the brightness slider down.
  • The "Auto-Brightness" option automatically adjusts the display to the lighting conditions. You can activate it in "Settings"> "General"> "Accessibility"> "Display Adjustments" by turning on "Auto-Brightness".

A WiFi connection consumes less power than the cellular network when you access data with the device. So always leave the WLAN activated. To access a WLAN network, activate WLAN under "Settings"> "WLAN".

Activate power saving mode.

The power saving mode introduced in iOS 9 makes it easy to extend the battery life of your iPhone when the power is running low. Your iPhone tells you when the battery level reaches 20% and reports back at 10%. Then you can turn on the power saving mode with a tap of your finger. You can also activate it by selecting "Battery" in the settings. The power saving mode reduces the brightness of the display, optimizes the performance and minimizes system animations. In addition, apps such as Mail do not load any content in the background and features such as AirDrop, iCloud synchronization and integration are disabled. But you can still make calls, use mail and messages, surf the web and more. And when your phone recharges, the power saving mode will automatically turn off.

Show information on battery consumption

With iOS you can easily manage the battery life of your device because you can see the consumption of every app (except when charging). You can find information on usage in the settings under "Battery".

Here are the notifications that can appear under the apps in use:

Background activity. This means that the app was using the battery while it was running in the background - that is, while you were using another app.

  • To save battery life, you can turn off the background update feature. Go to “Settings”> “General”> “Background Update” and select “WiFi”, “WiFi & Mobile Data” or “Off” to completely disable the background update.
  • If the Mail app shows the message "Background activity", you can choose to fetch the data manually or extend the time interval between fetching it. Go to Settings> Accounts & Passwords> Data Reconciliation.

Place and background location. This means that the app uses the location services.

  • You can extend battery life by disabling location services. You can deactivate this under “Settings”> “Data protection”> “Location services”.
  • All apps with their settings for access rights are displayed under "Location Services". For apps that have recently used the location services, you will see a corresponding note next to the on / off switch of the app.

Home and lock screen. This means that the home or lock screen was displayed on the device. For example, the display was brought out of the idle state by pressing the home button or by sending a message.

  • If an app frequently wakes up the display with notifications, you can deactivate push notifications for the app under “Settings”> “Notifications”. Just tap on the app and set the switch for "Allow notifications" to "Off".

No mobile reception and weak signal. This message indicates that you are either in an area with poor cellular coverage and your iOS device is looking for a stronger signal, or that you used your device with a weak signal, which in turn has reduced battery life.

  • Battery life can be extended by activating airplane mode. Open Control Center and tap the Airplane Mode icon. It is not possible to make calls when flight mode is switched on.

Plug in and turn on your computer to charge your device.

Make sure your computer is plugged into an electrical outlet and turned on if you are using it to charge your iOS device via USB. If the device is connected to a computer that is turned off or in hibernation, the device's battery may discharge. The iPhone 3G and iPhone 3GS cannot be charged using a FireWire power adapter or a FireWire car charger.

Tips for the Apple Watch

Update to the latest software.

Always make sure that you have the latest version of watchOS installed on your device.

  • In the Apple Watch app on your iPhone, go to “My Watch”> “General”> “Software Update” to see whether you need an update.
  • If an update is available, connect your iPhone via Wi-Fi, connect the charger to the Apple Watch (it should be at least 50% charged), and update wirelessly.

Adjust settings.

You can extend the battery life of your Apple Watch in a number of ways:

  • When running or walking, turn on the power save mode to turn off the heart rate monitor. To do this, open the Apple Watch app on your iPhone, go to "My Watch"> "Training" and switch on the energy-saving mode. When the heart rate monitor is switched off, the calorie consumption may not be calculated as accurately.
  • For longer training units, you can use a Bluetooth chest strap instead of the integrated heart rate monitor. To connect the Bluetooth chest strap to your Apple Watch, make sure that the strap is in the appropriate mode, go to "Settings"> "Bluetooth" on your Apple Watch and select it in the list of Health devices.
  • If you move your hands a lot and the display on your watch activates more often than you'd like, you can prevent the display from turning on every time you raise your wrist. Open the settings on the Apple Watch, select “General”, then “Activate display” and switch off “Activate display when raising your arms”. To activate the display, just tap it or press the Digital Crown.
  • If you turn off Bluetooth on your iPhone, it will increase the battery consumption of your Apple Watch. Leave Bluetooth turned on on your iPhone so that the connection between the devices is as efficient as possible.

Show information on battery consumption

For information about usage and sleep mode, start the Apple Watch app on your iPhone and go to "My Watch"> "General"> "Usage".

Plug in and turn on your computer to charge your Apple Watch.

If you want to charge your Apple Watch via USB using your computer, make sure that it is plugged in and switched on. If your Apple Watch is connected to a computer that is turned off or in sleep mode, the Apple Watch's battery can discharge.

To service your Apple Watch battery, contact Apple or an Authorized Service Provider.

Tips for iPod shuffle, iPod nano, and iPod classic

Update to the latest software.

Always make sure that you have the latest Apple software installed on your iPod. Place the iPod in the dock or connect it to the computer. iTunes will notify you when updates are available.

Optimize settings.

"Hold" switch and "Pause" button. Turn on the Hold switch when you're not using your iPod. This will prevent the iPod from being accidentally activated and thus using unnecessary energy. If you're not listening to music on your iPod, press the Pause button or turn it off by pressing and holding the Play button for about two seconds.

Equalizer (EQ). Adding an EQ for playback puts additional strain on the iPod processor because the EQ is not encoded in the song. Turn off the equalizer when you are not using it. However, if you've specified EQs for tracks in iTunes, you'll need to set the equalizer to “Linear” to turn it off, as the iPod doesn't make any changes to your iTunes settings.

Lighting. If the lighting is set to "Always on", this results in a significant reduction in battery life. So only use the lighting when you really need it.

Plug in and turn on the computer to charge your iPod.

Make sure your computer is plugged in and turned on when you use it to charge your iPod via USB. When iPod is connected to a computer that is turned off or in hibernation, the iPod battery can drain.

Tips for MacBook Air and MacBook Pro

Update to the latest software.

Always make sure that you have the latest version of macOS installed on your device. When connected to the Internet, macOS automatically checks for software updates every week. But you decide when the updates will be installed. To make sure you have the latest software, choose Software Update from the Apple menu.

Optimize settings.

Energy. The Power Saving Settings area includes several options that determine how much power the MacBook uses. The MacBook detects when it is plugged into an electrical outlet and behaves accordingly. When the MacBook is powered by the battery, it dims the display and uses other components sparingly. Changing the settings to increase performance will drain the battery faster.

Brightness. Dim the display to the lowest level of brightness that is comfortable to achieve maximum battery life. For example, if you are watching a video on an airplane, high brightness is not absolutely necessary when the lights in the cabin are off.

WIRELESS INTERNET ACCESS. The WLAN function also needs power when you are not currently accessing a network. You can deactivate it in the "WLAN" status menu in the menu bar or in the network settings.

Apps and peripherals. Disconnect peripherals and close any apps that are not in use. Eject SD cards when you are not accessing them.

Plug in and turn on MacBook to charge other devices.

Make sure your MacBook is plugged into an electrical outlet and turned on if you are using it to charge other devices via USB. Otherwise, the devices will drain your MacBook's battery faster than usual. If another device is connected to the MacBook, when it is turned off or in sleep mode, the other device's battery can drain.
