Simple Yet Effective Tips

First off, we shall begin with the simple solutions. In most cases, they can get your work done. In case, they don’t click, move on to the slightly advanced fixes.

Force Quit Apps When Not Needed

After using an app, many of us forget to quit it. As a result, it keeps on running in the background and eating the battery. Therefore, it’s better to force quit the app as soon as you have used it.

Force Restart Your Device

Whenever you find your iOS device draining the battery a bit too fast, the first solution you should try is force reboot it. What makes it so effective is the ability to flush out bad bits that tend to get stuck from time to time.

Make Sure to Turn Off Wi-Fi and Bluetooth When They Are Not in Use

Another simple thing you should always keep in mind is to turn off Wi-Fi and Bluetooth if you are not using them. Go to Settings → Wi-Fi/Bluetooth → Turn it off.

Turn Off Automatic Downloads and Updates

When you download an app on your iPhone, it’s automatically downloaded on your other iOS device synced with the same iCloud account. Hence, you don’t need to install it on your other device. Thought it’s a helpful feature, it can eat into some extra battery on your device.

If you have enabled automatic app updates, all of your apps are updated as soon as new versions are available. I find it very handy, but when I wish to have more control over the power consumption, I disable it.

Open Settings app → Tap on iTunes & App Stores → Under Automatic Downloads section, turn off the switch next to Music, Apps, Books & Audiobooks, and Updates.

Keep Display & Brightness in Check

Always be sure to keep display and brightness in check. I mean, keep it at the medium level.

Once you are in Display & Brightness section, the first thing I would tell you to do is turn off “True Tone.” Basically, it adapts the device display as per the ambient lighting conditions. As a result, colors appear to be consistent in different conditions. The only problem with this feature is that it doesn’t work all the time consistently. In this case, it’s better to adjust the brightness manually.

The second thing I would suggest you take care of is the Auto-Lock. Keep it as short as possible. If it’s set to Never, deselect it as the longer the screen remains awake the more battery is consumed.

And the third, turn off Raise to Wake. Every time you pick your device, you may not necessarily want to wake the screen. Therefore, it’s apt to disable it.

Avoid setting Display Zoom as your iPhone view. It’s wise to select the Standard view for iPhone as it’s more efficient and can extend the battery life of your iOS 12 device.

Step #1. Open Settings app → Tap on Display & Brightness.

Step #2. Now, turn off True Tone, and Raise to Wake. Make sure to set the auto lock to the minimum level.

The easiest trick is to keep your iPhone Face Down as much as possible. The sensors recognize the iPhone position and do not light up the display with a new notification. You’ll still hear the notification sound to let you know there’s something you need to look at.
