Some people just plug their phones into a charger whenever power is available. But in the long run, it can cause great damage to the battery itself. More ever, iPhone charger gets too hot sometimes.
Should iPhone charger get hot? Causes
Before we start talking about some serious issues that can affect battery life, try to exclude some environmental factors.
For example, avoid using your iPhone in very hot places, don’t leave your cellphone in the car when it’s too hot outside, etc.
Anyhow, your iPhone could get hot under normal circumstances.
Battery health
If you’ve had your iPhone for a few years, the battery has probably already run out a bit.
However, science says that charging your battery causes its performance to degrade over time, no matter how you do it.
The reason for this is in the fact that smartphones are powered by lithium-ion batteries, which work by shifting the charge from one electrode to another.
Moving those ions puts stress on the electrodes and leads to reduces battery life.
If you want to check iPhone battery health, just go to Settings > Battery and tap on Battery Health.
Maximum capacity- this is a measure of your battery capacity relative to when the battery was new.
The older your iPhone, the lower this number is likely to be.
Lower capacity may result in fewer hours of usage between charges.
Where we make mistakes during charging?
While the phone is connected to the charger, it heats up further. If it overheats, unplug it from the charger and wait for it to cool down a bit.
According to some researchings, heat is the worst enemy of batteries (but I think that we all knew that).
Also it is important to avoid using your iPhone while charging, downloading the apps, or installing updates as its temperature normally gets higher when carrying out there processes.
Tips for prolonging battery life
It’s a good idea to turn on notifications only for the applications we use the most.
Every time your phone gets a notification the screen lights up and you are tempted to swipe your finger to open that notification.
A small item that can extend battery life is to reduce the brightness of the phone.
Also, do not search for signal in low service areas.
If you are traveling in an area with poor signal coverage, switch the phone to airplane more.
You will not be able to receive calls, but this feature will extend your battery life because it will not constantly look for a signal.
However, it is normal for the charger to produce heat, but if it overheats, it is necessary to turn it off the charger and wait for it to cool down to prevent damage.
