iPhone won’t turn on or charge

The iPhone won’t charge in, which is the initial cause of the problem. When the iPhone isn’t charging, it will use its remaining power until it runs out; without a power source, the screen won’t light up.

There are many different causes for this. When there is a problem, the charger is too bad or not authentic. The iPhone charging hole is too dirty and clogged with foreign objects, preventing power from getting to the device and protecting it from the risk of fire and explosion.

iPhone died and won’t turn back on

Many people have experienced situations where their iPhone stopped working all of a sudden. This frequently occurs with older iPhone models, including those in the iPhone 6 to iPhone 8 series and some infamously buggy ones like the iPhone X .

Regarding the “fault king” iPhone X, Apple has admitted that there were problems with the research and development that resulted in a great number of mistakes.

iPhone overheated and won’t turn on

Performance of the iPhone is significantly impacted by temperature. When used in hot climates, the iPhone frequently experiences performance and brightness reductions to the point where the power is shut off and the iPhone won’t turn on.

This explanation is also reasonable. The iPhone will heat up and, to some extent, shut down to prevent the risk of engine explosion, especially when the operating system version is not well optimized or, in most cases, when using the phone in a hot environment, such as in the sun.

iPhone won’t turn on after update

This frequently occurs following significant updates; iOS 16 is the most recent instance. It frequently occurs with older models that aren’t designed for the most recent operating system (new operating systems will be released with an iPhone line, for example, iPhone 14 series and iOS 16 – which will only be best optimized for the previous 2 to 3 iPhone lines).

As a result, the device will be overloaded and defective after updating a new, heavy operating system on outdated machines, in addition to a number of other factors, leading to a crash and malfunction.

Way to fix the problems        

The best course of action is to start fixing your iPhone as soon as you’ve determined the potential errors that are causing it to stop working. The error will worsen and eventually become irreversible if it is delayed for a long time.

Wapolabs would like to share some easy fixes you can try at home to fix the problem with your mobile device.

Charging issue

Charger issues are one of the most frequent causes of the errors mentioned above. The act of directly supplying the iPhone with power to operate is known as charging. Without power, the iPhone won’t function and will shut down. If it doesn’t turn on, you can not find a solution to the issue.

Make sure that the power coming into the iPhone from its input to its output is of high quality to avoid charging issues. It is possible for the entire charging system to stall due to one subpar component, rendering the phone useless.

Some things you can do are:

  • Use a clean, reliable power source to charge your iPhone, for example.
  • Use a genuine Apple charger or a high-quality charger from a well-known tech brand like Anker; they all have the best protection for the iPhone’s battery.
  • Limit use of your iPhone while charging; charge it in a cool, stable environment, and don’t wear a case while doing so.
  • Clean the charging port: Foreign objects or dirt may partially or totally obstruct the charging process, resulting in unstable power transmission.
