How To Save Battery On iPhone 8

In the past, we published article How to increase battery life for iPhone 7. But today’s world is changing at a rapid pace, and new technologies are born every day. So we decided to refresh this topic and bring you an updated list of tweaks how to save battery on iPhone 8 or iPhone X.

Most of the tricks listed below are easy to implement and help you extend the iPhone battery life.


1. Check what is draining your battery

Knowing what’s likely to drain your battery is the first step to fixing it.  Your iPhone offers an easy way to check.

Go to Settings >> Battery. You can see the percentage of battery used by each app in the last 24 hours.


2. Enable Wi-Fi Assist

Wi-Fi is something that sucks a ton of battery from your iPhone. The problem is your iPhone usually desperately tries to hold onto a Wi-Fi signal–even when it’s only got one bar. This will drain battery like you can’t believe. To prevent this enable Wi-Fi Assist on your iPhone. Wi-Fi Assist automatically switches over to your cellular data connection when a Wi-Fi signal gets too low. Just be warned that enabling Wi-Fi Assist will mean you eat more of your data plan. To enable Wi-Fi Assist

To enable Wi-Fi Assist go to Settings > Cellular (or Mobile Data) and toggle the switch next to Wi-Fi Assist to ON (green).


3. Enable Low Power Mode

From iOS 9 there is a mode called Low Power Mode. This will automatically turn off all but the most needed power sucking features of the iPhone when you hit 20% battery power and then even more at 10%. But many people don’t realize you can enable Low Power Mode at any time, which you should do it you want to conserve battery.

To enable Low Power Mode manually go to Settings > Battery and toggle the switch to ON (green) next to Low Power Mode.


4. Stop Motion Effects

The parallax effect is the name given to the slightly moving icons and notifications in iOS when you move your iPhone. Apple created the parallax effect to give the flat icons some depth. However, as with any process that requires movement, the graphic capabilities needed to do this eats up battery life.

To disable this effect go to Settings > General > Accessibility > Reduce Motion > and toggle the switch to ON (green).


5. Disable Dynamic Backgrounds

Another motion feature in iOS is the dynamic backgrounds. These are the wallpapers that have subtle movement in them. They look cool, but that movement is eating into your precious battery life. It’s best to use a still image for your wallpaper.

To get rid of the dynamic images go to Settings > Wallpaper > Choose a New Wallpaper and select a wallpaper from the “Stills” selection.


6. Turn on Auto-Brightness

Increased screen brightness takes up a TON of battery power. This is because the extra light required to illuminate your screen requires a lot of energy, draining your battery faster. Screens generally require less light in darkness and more light when it’s bright outside.

To have your iPhone adjust to external brightness levels automatically go to Settings > Display & Brightness > and toggle the Auto-Brightness switch to ON (green).


7. Reduce Screen Brightness Manually

If Auto-Brightness isn’t good for you, you can also set the brightness levels manually.

Go to Settings > Display & Brightness > and reduce the brightness level by adjusting the slider. This will set the maximum value of screen brightness and can do a lot to saving that extra battery charge.


8. Turn Bluetooth Off

Bluetooth is also consuming power. So if you don’t need to have Bluetooth on, just turn it off.

To quickly switch Bluetooth off simply swipe up from the bottom of any screen in iOS. This will bring up the Control Center. Tap the Bluetooth button so it turns black. This disables Bluetooth.


9. Turn Off 4G

4G is another blessing of modern mobile networks, but it uses a lot more power than traditional 3G networks. Thankfully any iPhone that can connect to a 4G network can also still connect to a 3G network–and anywhere you can get a 4G signal you can almost certainly get a 3G signal. So if you’re running low on power and the fastest Internet speeds aren’t a priority at the moment, disable 4G on your iPhone. To do this go to Settings > Cellular (or Mobile Data) > Voice & Data and select 3G.


10. Turn Off Wi-Fi

Wi-Fi is another connection technology we generally don’t need when out and about. It’s more important when we are in our home or office as using Wi-Fi doesn’t eat into our data plans. But having it enables all the time means our phones are constantly looking to join Wi-Fi networks as we traps across the city or take a ride on the train. The result is battery drain.

To quickly switch Wi-Fi off simply swipe up from the bottom of any screen in iOS. This will bring up the Control Center. Tap the Wi-Fi button so it turns black. This disables Wi-Fi.


11. Prevent Background App Refresh

Background App Refresh is a feature in iOS that enable apps to learn when you frequently check them. This allows the apps to predict when you’ll next check them and sees them pining their servers right before you do so they can pull the latest data and have it ready and waiting for you when you open the app. It’s a really handy feature except in that it leads to battery drain since these apps are running in the background.

To disable Background App Refresh go to Settings > General > Background App Refresh >  and toggle the switch to OFF (white) or toggle individual apps ON or OFF.


12. Turn Off App Location Services

Location Services allows apps to know where you are based on your GPS or Wi-Fi triangulation. This is handy for a number of apps, but it drains battery power. Also, some apps request your Location Information yet it does you little good (these apps use it for targeted ads, for example).

To save battery go to Settings > Privacy > Location Services > and toggle the switch to OFF (white) to turn off all Location Services (not recommended) or toggle individual apps access ON or OFF.


13. Turn Off System Location Services

Just because you’ve tweaked individual app access to Location Services doesn’t mean you can’t get some further battery savings from disabling the feature in other places. The core of iOS uses Location Services for many other functions–some of which are pointless to you.

Go to Settings > Privacy > Location Services > and scroll down until you see System Services. Tap that and toggle the switches to OFF (white) to disable individual system Location Services. I recommend disabling Diagnostics & Usage and Location-Based iAds.


14. Turn “Hey Siri” Off

Siri is always working in the background as a default on iOS. She’s just sat there waiting for you to speak to her, meaning she’s always using up a little bit of battery in the background. It’s not helpful, especially if you don’t use her, plus it isn’t hard to just turn her on manually.

You need to head into Settings > Siri & Search and then toggle the switch to OFF (white) next to Listen for “Hey Siri”. Now you can’t call out to her to get into Siri but you can still do it with the home button.
