iPhone / iPad Battery Problems? Here's some tips on how to resolve it

Having battery problems with your iPhone? 
Battery Tip #1: Turning off Background App Refresh

Apple decided to automatically turn on “Background App Refresh,” a function that allows apps to constantly update and pull information from the internet even when you’re not actively using them. While you might want this for certain apps, you really don’t need it on for every app. I was seeing the battery on my iPhone 7 Plus drain in a matter of hours, when previously light usage would see it lasting the entire day.

Turning off background refresh has improved battery life dramatically. Here’s how to do it yourself:

  1. Open Settings
  2. Tap General
  3. Tap Background App Refresh
  4. Go through all your apps and turn off the ones that you don’t need to keep on—pretty much everything other than maps, email, news, and music apps
Battery Tip #2: Check your Battery Health in Settings
Battery Health (Beta)
For iPhone 6 and later, iOS 11.3 adds new features to show battery health and recommend if a battery needs to be replaced. These can be found in Settings > Battery > Battery Health (Beta).

Additionally, users can see if the performance management feature that dynamically manages maximum performance to prevent unexpected shutdowns is on and can choose to turn it off. This feature is enabled only after an unexpected shutdown first occurs on a device with a battery that has diminished ability to deliver maximum instantaneous power. This feature applies to iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7, and iPhone 7 Plus.

(Note: Devices updating to iOS 11.3 will initially have performance management disabled; it will be reenabled if the device subsequently experiences an unexpected shutdown.)

All iPhone models include fundamental performance management to ensure that the battery and overall system operates as designed and internal components are protected. This includes behavior in hot or cold temperatures, as well as internal voltage management. This type of performance management is required for safety and expected function, and cannot be turned off.
Battery Tip #3: Install a Battery App to check your battery health
Sometimes the default battery setting in your iPhone may not provide an accurate battery health check. twoSwitch Mobile recommends our viewers and customers to use Battery Health Doctor and you can download it on the App Store with this link

Battery Tip #4: Why Is My iPhone Overheating? Battery draining?

As you’re aware, your iPhone is a tiny little computer you carry around with you everywhere you go. It even has almost all of the same components as your computer – they’re just really, really small. You may also have noticed that unlike your computer, your iPhone doesn’t have have a fan, or any moving parts for that matter.

That’s not a problem until something goes wrong and your iPhone starts overheating. If you were to open up a desktop computer (preferably someone else’s), you would see a bunch of fans, but only one component would have a giant heat-sink and a fan plopped on top of it: the CPU. The part of your computer that heats up the fastest is the CPU, and the same goes for your iPhone.

Your iPhone is overheating because its CPU is revved up to 100%, all the time!

Here’s what I mean: The CPU of your computer or phone is a tremendously powerful chip, and it’s a lot like the engine of your car. When does your car use the most gas? When it’s accelerating. When you step on the gas, your car revs up until you achieve a cruising speed and let off the pedal. It takes a lot more work for a car to accelerate than it does to cruise.

Your iPhone’s CPU is so powerful that it rarely uses 5% of its capacity. If you’re reading this page using Safari on your iPhone, your iPhone should be nice and cool: You’re coasting. When you open an app like Safari, just like accelerating from a stop, your iPhone uses more CPU to get things going but very little once the app is loaded.

Your iPhone is overheating because the CPU is revved up to 100% even when the screen is off and it’s in your pocket.

In 99% of cases, when your iPhone is hot, you have a software problem.

How To Diagnose And Fix An iPhone That Gets Hot

1. Close Out Your Apps

First things first: We need to lighten the workload on your iPhone as much as possible, so let’s close out your apps. Double-click the Home Button (the circular button below your iPhone’s display), and swipe each app (except this one, if you’re reading on your iPhone) off the top of the screen. When you’re done, tap on Safari and come right back to this article.

2. Look For Crashing Apps: Part 1

How many apps have been crashing on your iPhone?
Ask yourself, “When did my iPhone first begin to overheat? Was it right after I installed a certain app?” If so, that particular app may be the offender. Need a hint? Head to Settings -> Privacy -> Analytics -> Analytics Data for a list of everything that’s been crashing on your iPhone.

Check analytics data for crashing app

It’s normal to see a few entries in this list because log files end up here too, but if you see the same app listed over and over again, you’ve got a problem with that app. Note: If the problem has been going on for a while and you don’t know which app started the problem, that’s OK too — just skip down to the next step.

Not All iPhone Apps Are Created Equal

With over 1 million apps in the App Store, you can be sure there are a few that have a bug or two. If you can, try downloading a different app that does essentially the same thing. For instance, if you downloaded “Bird Sounds Pro”, try “Songbird” or “Squawky”.

If you can’t afford to try a different app, try deleting it and reinstalling it from the App Store. To delete an app, press and hold on the app icon until it starts to wiggle and tap the black x that appears. Then head to the App Store and download it again

3. Look For Crashing Apps: Part 2

If your iPhone’s CPU is the engine, its battery is the gas. If an app is using a lot of battery life, it’s taxing your iPhone’s CPU. If an app you don’t frequently use is using a disproportionately high amount of battery, it could be crashing in the background of your iPhone.

Go to Settings -> Battery and look at the list of apps in the Battery Usage section to see which apps are using the most battery life and identify apps that could be causing your iPhone to get hot.

4. Turn Your iPhone Off And Back On

It’s a simple fix, but turning your iPhone off and back on can fix minor issues that accumulate with time. If one of those software issues was causing your iPhone to get hot, problem solved.

To turn your iPhone off, press and hold the power button until “slide to power off” appears on the screen, and then use your finger to swipe the power icon across the screen.

It’s normal for your iPhone to take 20 or 30 seconds to turn all the way off. To turn your iPhone back on, press and hold the power button until the Apple logo appears on the screen, and then let go.

5. Make Sure Your Apps Are Up To Date

App developers (the preferred term for computer programmers who make iPhone apps) don’t always release updates to add new features — a lot of the time, software updates are designed to fix bugs. As we’ve discussed, software bugs can cause your iPhone to overheat, so it’s important to make sure your apps are up to date.

To check for app updates, open the App Store and tap Updates at the bottom of the screen. If one or more of your apps can be updated, you’ll have the option to update your apps either one at a time or all at once. It won’t save you a lot of time, but I recommend tapping Update All if the option is available.

6. Update Your iPhone’s Software

Next question: “Are there any software updates available for my iPhone?” Apple periodically releases software updates that address issues that arise, some of which can cause certain apps to misbehave and your iPhone to get hot. To check, head to Settings -> General -> Software Update.
