Apple recently faced a battery of lawsuits as they revealed that they were intentionally slowing down older devices to save the battery. Yes, batteries are consumables and they wear off over time. They wear off faster with more charging cycles as well as improper phone usage habits. Here, we will talk about a bunch of ways that you can use to extend battery life on your iPhone, be it the iPhone X, the iPhone 7 or the iPhone 4 so that you spend less time by a power outlet and prevent premature ageing of your phone’s battery.
Before you proceed
Here are a few things that you need to know before you proceed with the list of tweaks for your iPhone – the list is optional. There’s always a price to pay. You cannot get better battery life and still use all the features of your phone, or have full performance.
So, if you think that there is something that you need to keep turned on, then do. There are a lot of other ways too that you can use to save your phone’s battery.
Restrict Location Services
Location services use a lot of battery even though they do not seem pretty harmless. Most of the iPhone models have small battery life and location services hit the battery the hardest. A large number of apps, from your cab-hauling app, your camera app, social network apps, all those track your location.
To track your location, your phone needs to communicate with a bunch of geostationary satellites without which it does not get the accurate location. As long as it does not get the accurate location, your phone keeps communicating. So, it’s better to turn off location services and only turn in on when you need it. Apps waking up in the background can also request device location. This drains a lot of battery.
To have more granular control, go to Settings → Privacy → Location Services and restrict location access to apps that you do not use much.
All iPhone models come with the auto brightness feature. The auto brightness uses a lux meter (which is a sensor above your screen) to detect ambient light and adjust the screen brightness accordingly. You may feel that manually adjusting brightness may be a better idea since the lux meter also consumes battery.
However, the fact is that you often overestimate the brightness of the screen. Moreover, you may be reluctant to reduce the brightness of the screen for when you are just peeking at your phone. But the lux meter automatically does it for you and manages to keep the power consumption much lower. In iOS 11, you get the auto brightness settings under Settings → General → Accessibility → Display Accommodations.
Since the screen is such a battery hog, you would want the screen to be off as much as possible. Using auto-lock helps that a lot. Most users have it turned on by default. However, in case you do not have it turned on, go to Settings → Display & Brightness → Auto-Lock. Here set the auto lock timer to be as low as possible.
This ensures that the screen turns off automatically when you are not using your phone.
Raise to Wake
Raise to wake is a new feature added on iPhone 6s onwards. Raise to wake uses a plethora of sensors to detect when you pick up your phone and uses that to unlock your phone. It is surely a convenience feature, but also is a battery drainer.
You can disable it under Settings → Display & Brightness. If you are habituated with this feature, when you may need a little time to get used to the lack of auto-unlocking.
Limit Background App Refresh
Reducing the number of apps that can refresh their data in the background also improves the performance on your phone. Background app refresh basically lets apps cache their data periodically so that they can launch faster. However, this refreshing process is processor hungry and obviously has a toll on the battery.
So, for apps that you may use once a week or so, you can turn off the background app refresh. You need to go to Settings → General → Background App Refresh to change which apps can refresh their data in the background.
Turn off Hey Siri
The “Hey Siri” feature listens to your phone’s microphone continuously. So, if you are not invoking Siri by calling out her name, you can easily disable this. Go to Settings → Siri & Search to change the setting.
There are obviously a ton of other things that you can do, such as uninstalling power-hungry apps, using a still wallpaper, using flight mode or reducing animations to save the battery. So what do you do to save power on your iPhone? Share in the comments below.
