Visit Your Settings!
According to this Reddit post by eavesdroppingyou, this simple trick can save you a considerable amount of space if you keep trying it. On your iPhone, click “Settings”, then “General”, then “Storage & iCloud Usage”. By simply visiting this page, your phone does some sort of background work to clear up some free space. Repeat this a few times, and you’ll notice that your storage space increases a bit.
This Reddit user speculates that your phone could be deleting unnecessary cached data from apps. Whatever the reason, it’s a neat little trick that’s worth trying.
Turn Off Background App Refresh
Whilst it’s great to keep your apps up to date, ready for when you open them next, leaving them to constantly refresh in the background also uses up your precious battery power. It’s worth turning off any background refreshing on Apps that you don’t use as often. To do this, head to ‘Settings’, then ‘General’, then ‘Background App Refresh’. You can decide to disable this feature entirely, or turn it off on selected apps.
Turn Off Automatic Updates
The later versions of iOS allow for any new updates to be downloaded automatically, so you won’t have to worry about constantly clearing the queue. However, choosing to save your app downloads for appropriate times will definitely help your battery to last longer. Also, this is handy for those of you who want to preserve their mobile data.
Turn Off Location Settings
Turning off location settings is one of the most successful ways of saving your phone’s battery. Again, head to ‘Settings’ then ‘Privacy’ then ‘Location Services’. You can choose to turn this feature off entirely, or turn it off on selected apps. With lower services looking for your location, your phone isn’t constantly using its in-built GPS to find relevant information-a real battery drainer!
Say Goodbye to Vibrate
It might not take up a lot, but letting your phone vibrate when you receive a call or message actually does drain your battery quite considerably. Head on over to ‘Settings’ then ‘Sounds’ to slide these off if you wish.
The brighter you have your screen, the more battery will drain. Try turning the brightness down, ensuring that ‘Auto Brightness’ is also turned off. This stops your phone from automatically adjusting the brightness depending on the lighting and time of day.
Switch Off Wi-Fi
If you know you’re not going to be near some Wi-Fi for a while, turn off this setting. This stops your phone from constantly searching for a hotspot. However, Apple Watch often uses Wi-Fi when it is available, so if you have one of those, it’s probably best not to toggle with this setting. You can also switch off your Bluetooth when you’re not using it for the same effect, but again, you’ll need this for the Apple Watch.
Browse the Battery Tab
Go to ‘Settings’ then ‘Battery’. This will show you a list of all of the apps you’ve used in either the past 24 hours or 7 days (depending on what tab you decide to click). Next to each app is a percentage that shows you how much of your battery has been drained by them. You can decide whether it’s worth deleting these apps, or if it’s worth just updating their settings. You can see what processes they’re taking by clicking each one. The notes underneath will explain how you can get this sorted (e.g. Facebook is a killer for background app refresh!).Turn Push Data Off
The default setting on the iPhone allows it to automatically search for new email and other data. However, this means that your phone is constantly looking for new information, which of course is a battery drainer. Turn off the ‘fetch new data’ setting and manually check your email yourself. You can do this by going to the ‘Settings’ app, clicking ‘Mail, Contacts, Calendar’ and then clicking ‘Fetch New Data’.
Don’t Quit Apps!
People often assume that double tapping to swipe up and clear your open apps will save on battery life. In fact, it takes more battery to do this process than it does to keep them open! Of course, if you want to keep things a bit less cluttered, clear them, but be aware that the more often you do this, the more your battery is prone to draining quicker.
Do A Full Drain
It’s worth noting that this is a good regular practice to get into, at least once a month if you can. Drain your phone completely, so the phone dies after 1%. Once it cannot power on again, connect it to a charger and let it completely charge to 100%. This actually refreshes the battery and gets it working how it should.
Buy A Portable Battery
If all else fails, it’s worth picking up a portable battery pack. This can be charged up and slotted in your bag in the event that you find yourself out for a long time and run out of juice. Your phone can be connected to these chargers so you can charge it on the move. Most are relatively cheap nowadays, but it’s worth checking out the official options available on Apple for the most effective versions.
