Sometimes, a dirty charging port can prevent your phone from charging properly, leading to battery drain. Use a soft brush or a can of compressed air to clean out the charging port gently.

Additionally, it’s important to ensure that you are using a good quality charging cable and wall charger. Using a subpar or damaged charging cable can result in inefficient charging, leading to faster battery drain. If your cable appears worn or damaged, consider replacing it with a new one. Similarly, if you notice that your USB port is loose or damaged, it may be worth getting it repaired or replaced.

In some cases, the battery drain issue may be caused by a faulty wall charger. If you suspect this to be the case, try using a different charger to see if the problem persists. If the battery drain improves with a different charger, it may be time to invest in a new one.

Lastly, keep in mind that certain usage patterns and settings can also contribute to battery drain on your iPhone 12 Pro. For example, having the screen brightness set too high, using power-hungry apps or features excessively, and keeping background app refresh enabled can all impact battery life. Adjusting these settings and being mindful of your usage habits can help optimize your iPhone’s battery performance.

If you are experiencing fast battery drain on your iPhone 12 Pro, there are several potential causes to consider. From adjusting your 5G settings to checking for app updates and ensuring proper charging equipment, taking these steps can help you optimize your iPhone’s battery life. By being proactive and making small adjustments, you can enjoy a longer-lasting battery on your iPhone 12 Pro.
