battery condition

Your iPhone uses a lithium-ion battery that has a limited lifespan.

Every time you charge and discharge your iPhone, you use up its maximum battery capacity.

Over two years (or about 500 charge cycles) you would expect to have about 80% battery capacity left.

This means that an iPhone that would have lasted 10 hours would now only last 8 hours without a charge.

You can check your battery health by going to Settings > Battery and tapping Battery Health.

If your iPhone has a very low battery condition and is draining too quickly, you should consider upgrading to a newer model.

Alternatively, you can get an out-of-warranty replacement battery from Apple for $69/£69. This is a much cheaper option than buying a new iPhone.

The phone runs slowly or restarts randomly

A slow iPhone isn’t always a cause for concern—but it could be.

It’s especially problematic when it happens frequently for no apparent reason. Often it can cause your device to reboot at random times.

A simple cause of your iPhone restarting is that it got too hot or too cold.

A cold start isn’t that bad – it should return to normal once the battery has warmed up.

But overheating can seriously damage parts of the iPhone, including the battery.

Other reasons for a slow phone could be internal damage or possibly a software issue – like a shady app.

If your iPhone turns off frequently (and not because of the temperature), you should have it checked.

Camera and microphone points

Your iPhone will show two warning signs when you are being spied on.

They appear as either green or orange dots at the top of the phone.

They don’t necessarily mean someone is snooping – but they could and do prompt you to investigate.

Added in an iOS update in 2020, the alert appears when your microphone or camera is activated.

That means if an app is secretly recording you, you will be warned about it.

To see the dots you must be using a device running iOS 14 or 15 – go to Settings > General > Software update to check.

A green dot appears in the upper right corner of the display when the camera is activated.

And it will be displayed in orange when the microphone is activated.

By swiping into your control center, you can see details about which app is using the microphone.

So if it’s an app that you think shouldn’t be using the camera or microphone, maybe you should be concerned.

If you think there’s something snooping on you when it shouldn’t, you should check the app’s permissions in Settings.

For example, you can even deny certain apps access to your microphone or camera.

And if you’re really concerned, you can just delete the app altogether.

ghosts touched

Ghost touches are when your iPhone “taps” parts of the screen without you doing anything.

It is very unusual for this to be a software issue.

Instead, it is most likely related to screen or water damage, or some other internal issue.

If you notice this (especially if it gets worse), take your iPhone to the Apple Store for a check-up.

It is possible that you will need to replace parts. This can get expensive, so depending on the model it can even be cheaper to buy a new iPhone.

Red water stripe

Water damage is the bane of every appliance owner’s life.

If liquid gets inside your iPhone, it can void the warranty and lead to costly repairs.

When you bring an iPhone in for repairs, Apple typically checks the Liquid Contact Indicator (LCI).

This is a part of the device that changes color when it comes into contact with water.

You can find it yourself: on newer iPhone models, it’s in the SIM card slot.

Use a flashlight and magnifying glass if you have trouble seeing the color.

The LCI is usually white or silver, but turns red after it has been in contact with water.

Apple has one side shows how to find the LCI on each iPhone model.

“An LCI activates when it comes into contact with water or an aqueous liquid,” Apple said.

“An LCI will not activate due to humidity and temperature changes that are within the environmental requirements of the product.”

Most modern iPhones are water resistant, but it’s a good idea to avoid getting soaked if possible.
