Understanding the Causes

App Overload

One of the primary culprits behind decreasing battery while charging an iPhone is power-hungry apps running in the background. These apps consume a significant amount of power, even when your phone is connected to a charger.

Solution: To identify these battery-draining apps, go to your iPhone's settings and check the Battery section. Here, you'll see a list of apps that are using the most power. Close these apps when charging or, better yet, consider uninstalling or replacing them with more efficient alternatives.

Cable and Adapter Issues

Another common issue is the quality and condition of your charging cable and adapter. Using subpar or damaged hardware can hinder your iPhone's ability to charge efficiently.


  1. Always use genuine Apple accessories.
  2. If your cable or adapter shows signs of damage, replace them immediately.
  3. Test different cables and adapters to ensure the issue is not with the hardware.

Updates and Fixes

Software bugs and glitches can also lead to decreasing battery while charging an iPhone. These issues can impact the phone's charging efficiency.


Ensure your iPhone's operating system is up to date. Apple frequently releases updates that address known issues. If the problem persists, restarting your device or performing a soft reset can often resolve minor software glitches. In extreme cases, using the iOS Recovery Mode might be necessary.

Extreme Temperatures

Temperature extremes, both hot and cold, can influence how your iPhone charges. High temperatures can cause your phone to heat up, which can impact the battery's performance, while extremely cold temperatures can slow down the charging process.


Charge your iPhone in a moderate-temperature environment. Avoid leaving it in direct sunlight or near heating sources. If your device gets too hot or cold, it's best to let it reach a more comfortable temperature before charging.
