If you want to change the charging icon on your device, the first step is to check if your device's operating system supports it. If you have an Android device, you can change the charging icon by using a third-party app from the Google Play Store. These apps allow you to customize the charging icon, battery level, and other related settings.
However, if you have an iPhone, the charging icon cannot be changed as it is part of the iOS system. You can, however, customize other visual aspects such as wallpapers, icons, and widgets through the iOS settings or by using third-party apps.
It's worth noting that changing the charging icon or other system-level settings may void your device's warranty, so proceed with caution. Additionally, some customization options may drain your battery faster, so make sure to monitor your device's battery life after making any changes.
