Turn Off Bluetooth, Wi-Fi, and Cellular
Using Bluetooth is a must for people with an Apple Watch and a pair of AirPods, and Wi-Fi and cellular data feel like a necessity when you’re using your iPhone.
Still, using these consumes battery life, which is the opposite of what you want when you’re running low.
To disable your Bluetooth, Wi-Fi, or Cellular, all you need to do is open your Control Center and turn off all the features you want.
If you need to, you can keep your cellular or your Wi-Fi, but turn the other one off. Usually, your iPhone keeps both on to search for the best connection when you need to, but in this case, you’re better off doing this manually.
Using 5G also takes more power, so if you have a 5G-capable iPhone model and really need to stay connected on the go, take a trip into Settings > Cellular > Cellular Data Options and select LTE instead. Depending on where you live, you might find an LTE connection is just as fast as 5G, which means you could be using more power for nothing.
