Optimized Charging (iPhone)

This feature is optional, but turned on by default after the upgrade. It is aimed at people who charge the iPhone overnight and therefore promote chemical aging of the battery because it is jam-packed for hours. Instead, the iPhone "learns" when it's needed again and only charges the battery to 80 percent during the night. The rest is added in the morning hours so that the iPhone is full again when the alarm clock rings. However, it may take a few days for the iPhone to learn when you get up. It can be found in the settings Battery/Battery health/Optimized battery charging

Battery Myths


Not fully charging will damage the battery, but plugging in and unplugging too often? Far from it, both supposed wisdoms belong in the realm of outdated battery myths. An overview.

1. The memory effect

It is often said that a battery should always be as empty as possible before it is charged. However, this does not apply to modern smartphone batteries, since they have lithium-ion batteries, explains the magazine "Connect" in its current issue. Nickel-cadmium batteries, on the other hand, can lose capacity over time if they are charged too early.

2. Incorrect power supplies

There is no wrong power supply, at least not with current smartphones that are charged via USB cable. Upstream charging electronics only allows a defined flow of energy to pass through. So you can use all suitable power supplies and also charge iPhones with Android chargers. However, not all smartphones support the same fast charging technologies. If in doubt, it will take longer with a third-party charger.

3. Charge properly the first time

The first charging process of a new smartphone doesn't have to be particularly long, and you don't have to fully charge the device either. This widespread view dates back to older battery technologies, but modern lithium-ion batteries don't get any better performance from it. So you can fully charge the first time you charge it - but you don't have to.

4. Plugging and unplugging too often damages the battery

Not true either. According to "Connect", rechargeable batteries only last a certain number of charging cycles. However, a charging cycle can also consist of several charging processes.

18 tips for longer battery life

With a few tricks, you can extend the iPhone battery life. We have put together useful tips for you that will significantly increase the runtime of the iPhone battery.

1. Update to the latest software

Apple recommends always using the latest iOS version to maximize iPhone battery life. Under Settings -> General -> Software update you can check whether an update is necessary. If an update is available, you can plug in your device and update over the air, or connect to a PC and update using iTunes.


2. Decrease auto lock time

Lock iPhone directly by yourself or shorten the lock time in Settings -> General -> Auto-lock.


3. Restart iPhone

Sounds simple but can help. The restart ends power-hungry processes and apps in the background.


4. Reset settings

Sounds simple but can help. The restart ends power-hungry processes and apps in the background.


5. Reduce screen brightness

The screen accounts for a large proportion of the power consumption of modern smartphones. You can save iPhone battery by reducing the screen brightness. To open Control Center, swipe up from the bottom. You can then move the brightness slider to the left. A useful option is "Auto-Brightness". When activated, the screen brightness automatically adjusts to the lighting conditions - so you can always read your display well and still save battery. You can enable auto-brightness under Settings -> Display & Brightness.


6. Issue location services

Determining your location via GPS costs a lot of electricity and is usually not needed in everyday life. Disable these in the settings under Privacy -> Location Services.


7. Activate power saving mode

If the iPhone battery level drops below 20 percent, you will be asked if you want to turn on battery saver mode. You can also switch it on manually under Settings -> Battery. With the power saving mode, you can significantly extend the runtime of the iPhone battery. It makes some settings that you could also manually set individually. For example, the power-saving mode disables e-mail retrieval, background updates, automatic downloads, and some visualizations.


8. Disable automatic app updates

Under Settings -> iTunes and App Store you can set that you have to approve each update manually.


9. Disable widgets

You can turn off power-hungry widgets in Notification Center.


10. Identify power-hungry apps

If you want to save iPhone battery, it helps to know which apps are using the most power. Under Settings -> Battery you can see the power consumption of individual apps in the last 24 hours or seven days. The clock display at the top right shows exactly how long the apps have been used in the foreground and background. With the knowledge of the power consumption of the apps, you can delete certain apps or use them less. The Facebook app is a prime example: it needs a lot of electricity. Alternatively, you can call up Facebook via the Safari browser, for example.


11. Manage push notifications

In the menu under Notification, you can define which apps will display push notifications.


12. Use static wallpaper

Dynamic wallpapers are nice to look at, but cost battery.


13. Save iPhone battery in airplane mode

To extend iPhone battery life, you can switch to Airplane mode when reception is poor. When cellular network quality is poor, your iPhone tries to make up for it and uses more power. Constantly switching between LTE, 3G and EDGE has a negative effect on the iPhone battery life. You can therefore save battery by activating the flight mode in areas with poor network. To do this, swipe up from the bottom: In the quick settings you will find the flight mode.


14. Change mail and calendar data synchronization

You can reduce the linked accounts in the settings under Mail, Contacts, Calendar. In addition, the check interval can be increased under data comparison.


15. WLAN instead of mobile network

If you want to extend iPhone battery life, use Wi-Fi as much as possible. This not only protects your data volume, but can also save battery: If the device is used to access data, a WLAN connection uses less power than the mobile network. To turn on Wi-Fi, swipe up from the bottom to open Control Center. Tap the WiFi icon and log into a network. You can also activate the WLAN via Settings -> WLAN.


16. Turn off Bluetooth

Bluetooth doesn't use a lot of battery, but you can turn it off when you're not using it.


17. Reduce exercise

Reduce processor performance and thus battery consumption in the settings under General -> Accessibility -> Reduce motion.


18. Avoid streaming videos and music

Streaming music and videos costs a lot of electricity. If your battery is already red, consider shifting fetching to Video & Music Streams when you're at the nearest power source.
