Maximising Battery Life and Lifespan‘Battery life’ is the amount of time your device runs before it needs to be recharged. ‘Battery lifespan’ is the amount of time your battery lasts until it needs to be replaced. Maximise both and you’ll get the most out of your Apple devices, no matter which ones you own. Tips for iPhone, iPad and iPod touchUpdate to the latest software.Always make sure your device is using the latest version of iOS.

When you use your device to access data, a Wi‑Fi connection uses less power than a mobile network — so keep Wi‑Fi on at all times. To turn on Wi‑Fi, go to Settings > Wi‑Fi to access a Wi‑Fi network. Enable Low Power Mode.Introduced with iOS 9, Low Power Mode is an easy way to extend the battery life of your iPhone when it starts to get low. Your iPhone lets you know when your battery level goes down to 20 per cent, and again at 10 per cent, and lets you turn on Low Power Mode with one tap. Or you can enable it by going to Settings > Battery. Low Power Mode reduces display brightness, optimises device performance and minimises system animations. Apps including Mail will not download content in the background, and features like AirDrop, iCloud sync and Continuity will be disabled. You can still use key functions like making and receiving phone calls, email and messages, accessing the internet and more. And when your phone charges up again, Low Power Mode automatically switches off. View battery usage information.With iOS, you can easily manage your device’s battery life, because you can see the proportion of your battery used by each app (unless the device is charging). To view your usage, go to Settings > Battery. Here are the messages you may see listed below the apps you’ve been using: Background Activity. This indicates that the battery was used by the app while it was in the background — that is, while you were using another app.
Location and Background Location. This indicates that the app is using Location Services.
Home & Lock Screen. This indicates that the Home Screen or Lock Screen was displayed on your device. For example, the display was awakened by pressing the Home button or by a notification.
No Mobile Data Coverage and Low Signal. This indicates either that you are in a poor mobile coverage area and your iOS device is searching for a better signal or that you’ve used your device in low-signal conditions, which has affected your battery life.
Plug in and power on your computer to charge your device.Make sure your computer is plugged in and powered on when you’re using it to charge your iOS device via USB. If your device is connected to a computer that’s turned off or is in sleep or standby mode, your device’s battery may drain. Note that iPhone 3G and iPhone 3Gs cannot be charged with a FireWire power adapter or FireWire-based car charger. Tips for Apple WatchUpdate to the latest software.Always make sure your Apple Watch is using the latest version of watchOS.
Learn more about updating watchOS Adjust your settings.There are a few ways you can preserve battery life on your Apple Watch:
Enable Low Power Mode.Introduced with watchOS 9, Low Power Mode is an easy way to extend the battery life of your Apple Watch when needed, for example if you’re on a long flight or find yourself without your charger for the night. You can enable it by swiping up to Control Centre and tapping on the battery percentage, or by going to Settings > Battery. Low Power Mode prolongs battery life by turning off always-on display; limiting the mobile network and Wi-Fi connections of your Apple Watch; and disabling background sensor readings including heart rate measurements, high- and low-heart-rate notifications, irregular rhythm notifications and blood oxygen measurements. When not connected to your iPhone, your Apple Watch will attempt to retrieve notifications approximately once an hour. When your Apple Watch battery reaches 80 per cent charge, Low Power Mode automatically switches off. View battery usage information.To view your battery usage and charging history, open the Settings app on your Apple Watch and go to Battery. Plug in and power on your computer to charge your Apple Watch.If you want to charge from your computer, make sure it is plugged in and powered on when you’re using it to charge your Apple Watch via USB. If your Apple Watch is connected to a computer that’s turned off or is in sleep or standby mode, the Apple Watch battery may drain. If your Apple Watch battery needs service, use Apple or an authorised service provider. Tips for iPod shuffle, iPod nano and iPod classicUpdate to the latest software.Always make sure your iPod is using the latest version of Apple software. Put your iPod in its dock or plug it into your computer, and iTunes will notify you of available updates. Optimise your settings.Hold and pause. Set the Hold switch when you’re not using your iPod. This will prevent iPod from accidentally waking up and using unnecessary power. If you’re not listening to your iPod, pause it, or turn it off by pressing the Play button for two seconds. Equaliser (EQ). Adding EQ to playback increases use of your iPod processor, since EQ isn’t encoded in the song. Turn off EQ if you don’t use it. If, however, you’ve added EQ to tracks in iTunes, you’ll need to set EQ to “flat” to have the effect of “off”, because iPod keeps your iTunes settings intact. Backlight. Setting the backlight to “always on” will significantly reduce your battery life. Use the backlight only when necessary. Plug in and power on your computer to charge your iPod.Make sure your computer is plugged in and powered on when you’re using it to charge your iPod via USB. If your iPod is connected to a computer that’s turned off or is in sleep or standby mode, the iPod battery may drain. Tips for MacBook Air and MacBook Pro.Update to the latest software.Always make sure your MacBook is using the latest version of macOS. If you’re connected to the internet, macOS automatically checks for software updates every week, but you still control when the updates are installed. To confirm that you’re using the latest software, go to the Apple menu and choose Software Update. Learn more about updating macOS Optimise your settings.Energy. The Energy Saver preference pane includes several settings that determine power levels for your MacBook. Your MacBook knows when it’s plugged in and runs accordingly. When using battery power, it dims the screen and uses other components sparingly. If you change this setting to maximise performance, your battery will drain more quickly. Brightness. Dim the screen to the lowest comfortable level to achieve maximum battery life. For instance, when watching a video on an aeroplane, you may not need full brightness if the cabin lights are off. Wi-Fi. Wi-Fi consumes power, even if you are not using it to connect to a network. You can turn it off in the Wi-Fi status menu in the menu bar or in Network preferences. Applications and peripherals. Disconnect peripherals and quit any applications you’re not using. Eject an SD card if you’re not currently accessing it. Plug in and power on your MacBook to charge other devices.Make sure your MacBook is plugged in and powered on when you’re using it to charge other devices via USB. Otherwise those devices may drain the battery in your MacBook faster than normal. If another device is connected to your MacBook when it’s turned off or in sleep or standby mode, the device’s battery may drain. Tips for Extending Battery LifespanAutomatic battery health management.To reduce battery ageing, built-in software and hardware systems are included to manage charging patterns and battery temperature.
Avoid extreme ambient temperatures.Your device is designed to perform well in a wide range of ambient temperatures, with 16° to 22° C (62° to 72° F) as the ideal comfort zone. It’s especially important to avoid exposing your device to ambient temperatures higher than 35° C (95° F), which can permanently damage battery capacity. That is, your battery won’t power your device as long on a given charge. Charging the device in high ambient temperatures can damage it further. Software may limit charging above 80 per cent when the recommended battery temperatures are exceeded. Even storing a battery in a hot environment can damage it irreversibly. When using your device in a very cold environment, you may notice a decrease in battery life, but this condition is temporary. Once the battery’s temperature returns to its normal operating range, its performance will return to normal as well. iPhone, iPad, iPod and Apple Watch Comfort ZoneToo Cold Room Temperature Too Hot iPhone, iPad, iPod and Apple Watch work best at 0° to 35° C (32° to 95° F) ambient temperatures.

Storage temperature: –20° to 45° C (–4° to 113° F) Remove certain cases during charging.Charging your device when it’s inside certain styles of cases may generate excess heat, which can affect battery capacity. If you notice that your device gets hot when you charge it, take it out of its case first. Store it half-charged when you store it long term.If you want to store your device long term, two key factors will affect the overall health of your battery: the environmental temperature and the percentage of charge on the battery when it’s powered down for storage. Therefore, we recommend the following:
Depending on how long you store your device, it may be in a low-battery state when you remove it from long-term storage. After it’s removed from storage, it may require 20 minutes of charging with the original adapter before you can use it.
