When the iPhone is used for a long time, the battery life of the battery will gradually decrease and will affect the usage process such as sudden shutdown. The following article will guide you on how to check if the iPhone battery is swollen or not.

Causes and how to recognize swollen iPhone battery

Causes

Users may notice a significant decrease in the quality of the iPhone battery after a period of use. Some reasons for this phenomenon are:

Using a non-Apple-certified charger will reduce the battery life over time.
Users have the habit of using and charging the iPhone at the same time, which leads to the battery having to work continuously.
Using the iPhone too much without rest. In Vietnam, many users have the habit of using the iPhone all day long. The frequency can be up to 18 hours per day, causing the iPhone to operate continuously and consume battery.

How to recognize

Some signs to identify a swollen iPhone battery:

The battery charges quickly and drains quickly. The normal charging time is 2 – 3 hours, if the battery is swollen, it only takes 30 – 45 minutes to charge fully.
Playing games will drain the iPhone battery quickly. However, if your battery runs out quickly when you are not playing games and only performing normal tasks such as sending messages, making calls, or browsing the web, it is a sign that the battery is swollen.
Another way to identify a swollen battery is when you have just fully charged the battery (100%) and have not performed many tasks on the iPhone, but the battery still drains in a short period of time.
