The iPhone 7 has a larger battery than the iPhone 6s. This means that the battery life should improve. However, many users are reporting a consistently poor battery life even when they are not using their phone very much. Most of the complaints started pouring with the iOS 10.2 update. For most people it was found that the comparatively better-performing chip and powerful graphics chip was the reason why the phone lost a lot of battery, but for others, the problem seemed to be related to the hardware. Some of the ways in which you can fix these problems are:
Solution 1: Use Low Power Mode
By using low power mode you will be able to save a lot of battery but that comes at the cost of losing on background syncing abilities, Hey Siri and lesser animations. You can activate low power mode by:
- Going to the Settings menu of the phone
- Then heading to Battery
- Here you will be able to toggle on Low Power Mode
Solution 2: Check if a particular app is draining the battery
Sometimes it is not the phone but an app that may be causing the problem. Check if a third party app may be draining your phone of its battery by going to Settings and then tapping on Battery. Look up the different apps that are using the battery of your device and if you find an app that is chewing into your battery way more than expected, then you may want to uninstall that app.
Solution 3: Take the phone to the Apple Store
If your phone seems to be using a lot of battery even in low power mode, and there is no rogue app to be blamed for the problem, then there may be a problem with the actual battery of the phone. Visit an Apple Store to find out if you can get a replacement for your phone if it is under warranty.
