Most of the users of iPhone 12 also face the problem that their cellular data needs to be fixed. They have issues while gaming, browsing, and on video calls. The reason behind cellular data failure is that you may need stronger cellular coverage in the area you live in. 

Sometimes it also happens that too many people are connected to a network, and it gets overloaded, which ultimately causes network problems. Other reasons can be that your software needs to be fixed or your phone has minor bugs. It is also possible that your network connection has a problem at the back end. But the good thing is that we have developed an easy solution guide for all these things below:

First of all, you need to check your internet connection. If your internet connection is unstable, your iCloud syncing will slow down.

b) Upgrade Your iCloud Storage:

Usually, an iPhone gives you only 5 GB of storage. It may be possible that iCloud may have run out of storage, so check your storage first. If your storage is full, upgrade it according to your need to restart the syncing process. If you can't upgrade, try deleting some files to make some space.

c) Verify Your iCloud account:

Sometimes, your iCloud account might require verification to function correctly. To do this, go to your iCloud settings and follow the instructions to complete the verification process. That may involve sending a code to your phone number or email address associated with your iCloud account.

10. iTunes and App Store Problems

Users say that when they use iTunes and the App Store on the iPhone 12, they face trouble loading or refreshing the page properly. That annoys many people when it lags while downloading an app or refreshing the page. For that, you need to follow these steps:

a) Confirm the Status of Apple's System

First, you must determine whether the issue is from your side or the back end. You have to go to Apple's system status page. There you will get confirmation about if there is an issue from Apple's end or a problem with your device.

Another reason can be the weak internet connection. iTunes or the App Store require a strong internet connection to run smoothly. So try to get you a stable connection to solve this issue.

Lastly, you can restart your iPhone. Use your power button and press the slider towards OFF. Also, if your phone shows the software update option, you must Install your new software. To do that, go to settings, click general, and then click software update.

11. Battery Drainage

A common problem seen in iPhones is their battery which drains very quickly. However, the battery of Apple's new models is quite good. Especially if we talk about the iPhone 12, its battery is impressive. But due to constant use, it starts to degrade early. Try the following methods to solve it: 

Battery Drainage of iPhone 12

a) Use the Original Charger: 

First, iPhone battery problems usually occur because people don't use their original charger, so it's better to use your original charger. Use the most compatible one if you still need the original charger to avoid battery drain problems. 

b) Avoid Overcharging: 

Even if you overcharge your phone, your battery will be damaged. The iPhone battery starts to drain very quickly. So it is best to charge your battery from 20% to 80%. Refrain from charging below 20% and should not exceed 80% because, between these percentages, your battery will perform at its maximum.

c) Low Power Mode: 

If your brightness is too high, your battery may be drained. So try to turn on the low power mode; this feature will reduce your battery consumption. You can clear your history of unused apps running in the background so that they can save your battery. You can also save your battery by turning down the brightness. 

d) Battery Replacement:

If your battery does not work properly even after you use any of the solutions above, you should buy your new battery from the Apple store.

12. Overheating Issues

Overheating is a common issue that many iPhone users have complained about, especially in the iPhone 12. It has major common reasons, which we have listed below and provided their solutions, so please read them:

a) Heavy Workloads: 

The most overheating occurs when you are using a heavy app on your iPhone, for example, streaming video or doing CPU-intensive tasks, which causes your mobile to tip over. And it drains the battery too. So you should avoid such tasks or use applications that cause overheating. 

b) Exposure to Sunlight: 

The iPhone is sensitive, so it will get hot if you use your mobile in sunlight for a long time.

c) Airtight Cover: 

Most people use very airtight silicon covers, due to which your mobile phone heats up. So try to use covers that do not cause your mobile phone to heat up. 

13. Easily Scratched Screen

The 12 series is considered one of the best smartphones in the market as it packs a lot of advanced features and has a very cute sleek design. But the screen of the iPhone 12 should be more scratch resistant. That is a major drawback that users have complained about a lot. 

Apple introduced Ceramic Shield in iPhone 12, which they claim to be four times stronger than its previous iPhone models. 

However, Apple has made it softer to reduce the probability of glass cracking. That makes it more fragile to scratches. That results in a decrease in the quality of the glass, causing users to deal with numerous scratches and marks on their screens. Prevention is the best way to protect your screen. So you should invest in a good screen protector to protect your screen from scratches. You can get the best screen protector from Roobotech. But if you already have scratches on your screen, you can do these steps to remove those scratches. 

a) Use a Microfiber Cloth: 

You can use a microfiber cloth to clean your screen. That will remove all dust particles on your screen. These particles cause scratches when you put your phone in your pocket or bag. 

b) Avoid Abrasive Cleaners: 

Do not use chemicals or abrasive materials to clean your screen that may scratch or defect your screen.

c) Handle Your iPhone carefully: 

Take care of your iPhone and try not to hit it with any object that can impact it. Get a good strong protective case for its back protection. If you have a problem getting a case, you can buy a good protective case from Roobotech.
