Updating iphone takes forever
Apple currently offers the standard i Phone 8, i Phone 8 Plus, i Phone 7, i Phone 7 Plus, i Phone 6s, i Phone 6s Plus, and the smaller i Phone SE.
Between them, they're rated for 10 to 12 hours of battery life while browsing the web, checking email, and chatting.
If you see Facebook there and it says 4% on screen and 40% on background, it's a sign something has gone wrong.
At that point, you can force quit a rogue app and likely get your power consumption back to normal.
If you've just upgraded to a new i Phone 8 or i Phone X, updated to i OS 11, or restored, give things a day or so to finish up and go back to normal. That's especially true with things like Animoji, Portrait Lighting, and Augmented Reality (AR) apps.
So the screen stays on, storage gets written to, WI-Fi and maybe cellular radios stay lit up, and power gets consumed. When you pick it back up, note down how much battery life you have left again.
Yes, it can be an incredible pain in the apps, but if you have a significant and continual problem, and nothing else can fix it, setting up as new can be a solution. You will have to set up almost everything again, including passwords and settings, and you will lose all your saved data like game levels, health, and activities, but in most cases, your battery life will be better than ever. 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.
If you need to go longer than the built-in battery in your i Phone will allow, one option is to get an external battery. A battery bank can come in all shapes and sizes and can often charge multiple devices, even at once.
Every once and a while, you get a problem you just can't solve. If you have Apple Care or Apple Care , you should absolutely book a Genius Bar appointment and avail yourself of it.
You can also switch on Low Power Mode quickly by using Siri. " Note: On i Phone 8 and i Phone X, Low Power Mode also reduces the frequency of GPS updates, 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. If it's winter, try not to leave your i Phone on a heater or in front of a hot air vent, even in your car.
