How To Fix IPhone Battery Life Problems

If you need to go longer than the built-in battery in your iPhone will allow, one option is to get an external battery. You can either get a battery case or. A battery case keeps everything tightly packed together but limits the size and scope of the power source — it can't be too big to fit in your pocket, and it typically can't power other devices as well.

A battery bank can come in all shapes and sizes and can often charge multiple devices, even at once. I have both a battery case for my iPhone 7 and a battery bank with two charging ports for my iPhone 8 Plus, iPhone X, iPad Pro, and even USB-C MacBook Pro. They've both been lifesavers, especially when traveling. If your battery life is normal but you want to get even more out of it, case or no case, you can use Low Power Mode. It turns off processes and otherwise conserves as much power as it can.

1. Launch the Settings app from the Home screen. Toggle Low Power Mode to on. You can tell when Low Power Mode is enabled by looking at the color of the battery icon — it turns yellow. It will automatically turn off any time you recharge above 80% or more, so if you want to keep it on, you'll need to switch it on every time.

You can also switch on Low Power Mode quickly by using Siri. If even Low Power mode isn't enough — you're stuck in the wilderness, at a conference with poor reception and no power — there are a few other hacks you can try. Turn down the screen brightness. Set Auto-Lock to 1 minute.



Use headphones instead of the speaker if you have to listen to audio or music. Hide the Clock app in a folder. That animation uses GPU cycles. Batteries hate heat. It shortens their lifespans considerably. If it's summer, try not to leave your iPhone lying in direct sunlight or in an extremely hot environment. If it's winter, try not to leave your iPhone on a heater or in front of a hot air vent, even in your car.
