Using an iPhone is fun until you run out of battery juice, so if your power bank isn’t with you then these tips are great to help to conserve your phone’s energy.
Turn on Auto-Brightness/Lower Screen Brightness
The iPhones are equipped with an ambient light sensor that automatically adjusts the brightness based on the lighting condition of the place making it easier to see. It can save hours of your battery juice switching on.
Settings > Display & Brightness/Brightness & Wallpaper > Auto-Brightness Slider
If you’re not comfortable in this mode, you can just manually adjust your screen brightness.
Turn on Airplane mode
When you know you’re going to a place with a weak cellular connection, the best thing to do is just turn on the Airplane mode or else your phone will drain its battery pointlessly trying to connect to a network.
Settings > Airplane mode or you can just swipe up to adjust to control center.
Keep connections off
Do not keep your connections on especially when it is not needed. When you’re connected to the internet, turn off the mobile data or vice versa.
Settings > Cellular > Cellular Data or you can just swipe up to adjust to control center.
Bluetooth can also drain the battery juice, just turn this setting on when you want to transfer data but immediately turn off after using.
Settings > Bluetooth or you can just swipe up to adjust to control center.
There are applications that consume your battery even without using them, these apps constantly run in the background so that you’ll be updated.
To switch this off, Settings > General > Background App Refresh
This is a really useful feature so this one is only recommended if you’re squeezing your battery life.
Find battery killer apps
When iOS 8 came on iPhones, it added the Battery Usage feature that shows which apps consume most power over the last 24 hours and the last 7 days.
To discover battery killer apps, Settings > Battery
Don’t automatically upload to iCloud
Automatically uploading on iCloud also sucks battery life. So, if you want to upload data on your iCloud, make sure it’s intentional so that it won’t affect you particularly when you are running out of battery juice.
Settings > Photos & Camera > My Photo Stream
Turn off unneeded vibrations
Vibrate feature is useful when you still want to be notified without using any notification sound however it sucks up most of the power among the three options.
Settings > Sounds & Haptics > Vibrate on Ring
Force quitting apps is a bad idea
You might think that this action helps on saving you battery and memory as well then think again. When you want to open these idle apps, they just pick up from where you left off. Meaning, force quitting and launching these apps to start over is intensive.
Enable Low-Power mode
Now this one is highly recommended when you want your phone to last for a long time. According to Apple, turning this on will get you up to 3 hours. This feature shuts down all features that aren’t needed to conserve energy as much as possible.
Settings > Battery > Low Power Mode
One of the habit every time we go to bed is we charge our devices so that in the morning it is good to go. This is alright and safe, but then again, not ideal especially when you want your phone battery to last for a long time.
Charging overnight makes your phone stay fully charged for a long time thereby degrading its capacity much sooner. So even if manufacturers do their best to cover this, it still lowers the capacity of your phone’s battery.
The damages will be visible for the next two years or more so if you’re planning to use your phone for a long time then doing this simple tip won’t hurt.
