5 Common Myths About Smartphone Charging: What Really Harms the Battery.

There are various pieces of advice among users regarding the proper charging of a phone, but it is essential to understand how they actually work.

You should completely discharge your phone before charging

It is often advised to wait until 0% to prolong the battery life, but this is not necessary. Modern lithium-ion batteries do not require complete discharge, so it is optimal to charge when the battery level is at 20-30%.

Charging overnight harms the battery

The fear of leaving the phone charging until the morning is unfounded. Modern smartphones automatically control the charging process even after reaching 100%, so overnight charging is safe for the battery.

A higher charging power always means faster charging

It is important that the charger is compatible with the phone. High charging power does not always mean faster charging. For example, the iPhone works optimally with the appropriate charger, rather than the most powerful one.

Charging with the screen on is harmful

The misconception that charging with the screen on can lead to overheating is incorrect. Modern smartphones can monitor temperature and avoid damage from overheating.

Only original accessories are necessary

While brand-name chargers are a reliable choice, high-quality certified accessories from third-party manufacturers are also safe. The main thing is that the accessory meets quality standards.

It should be noted that the smartphone charger can heat up noticeably during prolonged connection, and this is not always a sign of malfunction. At the same time, it is essential to distinguish between mild warmth, which is considered normal, and overheating, which can be dangerous for the device and the user.

It is also worth remembering that the habit of fully discharging the phone can harm the battery much more than it may seem. Lithium-ion batteries do not handle deep discharge well, which can lead to reduced capacity and faster wear.
