Apple iPhones are well-oiled machines, but there are some telltale signs that everything is working fine.
From accidental water damage to signs of spying, we reveal six clues that something is wrong with your iPhone.
Your iPhone uses a lithium-ion battery, which has a limited life.
Every time you discharge and charge your iPhone, you deplete its maximum battery capacity.
Over two years (or around 500 charge cycles), you would expect around 80% of battery capacity to remain.
This means that an iPhone that would have lasted 10 hours of use would now only survive an 8-hour period without charging.
You can check your battery status by going to Settings > Battery and tapping Battery status.
If your iPhone has very low battery health and is draining too quickly, consider upgrading to a newer model.
Alternatively, you can get an out-of-warranty battery replacement from Apple for $69/£69. It’s a much cheaper option than buying a new iPhone.
Phone rebooting randomly
Randomly restarting your iPhone isn’t always a major cause for concern, but it could be.
This is especially problematic if it happens often, for no apparent reason.
A simple cause of your iPhone restarting is that it got too hot or too cold.
A cold reboot isn’t too bad – it should go back to normal once the battery warms up.
But overheating can seriously damage certain parts of the iPhone, including the battery.
Other reasons for restarting can be internal damage or possibly a software issue, like a dodgy app.
If your iPhone is shutting down frequently (and not due to temperature), you should have it checked.
Camera and microphone points
Your iPhone has two warning signs to show if you are being spied on.
They will appear as green or orange dots at the top of the phone.
They don’t necessarily mean someone is spying – but they could, and can prompt you to investigate.
The alert was added in an iOS update in 2020 and appears whenever your microphone or camera is activated.
This means that if an app secretly records you, you will be notified.
To see the dots, you need to be using a device running iOS 14 or 15 – go to Settings > General > Software Update to check.
A green dot will appear in the upper right corner of the screen when the camera is activated.
And it appears in orange if the microphone is activated.
By swiping up in your control center, you will be able to see details about the app that is using the microphone.
So if it’s an app that you think shouldn’t use the camera or microphone, you might want to worry.
If you think something is spying on you when it shouldn’t be, you should check the app permissions in the settings.
You can even deny specific apps access to your microphone or camera, for example.
And if you’re really worried, you can just delete the app completely.
More iOS updates
Apple regularly releases new versions of its iPhone software – and we’re currently on iOS 15.
Eventually, Apple stops supporting older models with updates, which is really bad news if you’re concerned.
These updates include vital security updates that fix serious issues with your device.
So if you can’t get these updates, you run a serious risk of being hacked.
The current iOS 15.4 supports phones since iPhone 6S and iPhone SE (1st generation).
Check if you’re still getting the latest updates in Settings > General > Software Update.
If not, it is highly recommended to upgrade your iPhone to a newer model which is still receiving security updates.
Ghost touches occur when your iPhone “touches” parts of the screen without you doing anything.
It is highly unusual for this to be a software issue.
Instead, it’s most likely related to screen or water damage, or some other type of internal issue.
If you notice this (especially if it gets worse), take your iPhone to the Apple Store for a checkup.
You may need to replace parts. This could end up being expensive, so it may even be cheaper to buy a new iPhone depending on the model.
red water band
Water damage is the bane of every gadget owner’s life.
If liquid gets inside your iPhone, it can void the warranty and lead to costly repairs.
When you get an iPhone repaired, Apple usually 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 recent iPhone models, it’s inside the SIM card slot.
Use a torch and magnifying glass if you have trouble seeing color.
The LCI will normally be white or silver but turns red if it has been in contact with water.
Apple has a page revealing how to find the LCI on each iPhone model.
“An LCI will be activated when it comes into contact with water or a liquid containing water,” Apple said.
“An LCI will not activate due to changes in humidity and temperature that are within the environmental requirements of the product.”
Most modern iPhones are water resistant, but it’s a good idea to avoid soaking whenever possible.
