In order to elongate the life of your iPhone, it is important to monitor its battery health at regular intervals. A healthy practice ensures that you can use your iPhone for an extended period of time. There are some ways in which you can maximize the battery life of an iPhone. In this article, we will guide you on the practices that users can follow to keep their battery fit. Here are few tips to optimize the battery life of an iPhone:
Update to the latest software
Always make sure your device is using the latest version of iOS.
- Go to Settings > General > Software Update.
- If an update is available, you can plug your device into a power source and update wirelessly or plug it into your computer and update with the latest version of iTunes.
Optimize your settings
You can preserve your battery life in two simple ways- adjust your screen brightness and use Wi-Fi. Dim the screen or turn on Auto-Brightness to extend battery life.
- To dim, open the Control Centre and drag the Brightness slider to the bottom.
- Auto-Brightness adjusts your screen to lighting conditions automatically. To activate it, go to Settings > General > Accessibility > Display Accommodations and set Auto-Brightness to On.
A Wi‑Fi connection uses less power than a cellular network. Therefore, 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
Low Power Mode 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. The feature reduces display brightness, optimizes device performance and minimizes system animations. When your phone charges up again, Low Power Mode automatically switches off. 
View Battery Usage details and manage it
With iOS, you can easily manage your device’s battery life, because you can see the proportion of your battery used by each app (not when the device is charging). To view your usage, go to Settings > Battery.
- To improve battery life, you can turn off the feature that allows apps to refresh in the background. Go to Settings > General > Background App Refresh and select Wi-Fi, Wi-Fi & Mobile Data, or Off to turn off Background App Refresh entirely.
- If the Mail app lists Background Activity, you can choose to fetch data manually or increase the fetch interval. Go to Settings > Accounts & Passwords > Fetch New Data.
- You can optimize your battery life by turning off Location Services for the app. Turn off in Settings > Privacy > Location Services.
- In Location Services, you can see each app listed with its permission setting. Apps that recently used location services have an indicator next to the on/off switch.
- If an app frequently wakes your display with notifications, you can turn off push notifications for the app in Settings > Notifications. Tap the app and set Allow Notifications to Off.
- You can optimize your battery life by turning on Airplane mode. Open Control Centre and tap the Airplane mode icon. Note that you cannot make or receive calls while in Airplane mode.

Plug in and power on your computer to charge your iPhone
Make sure your computer is plugged in to a power source, 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, the battery of your device may drain.
