An iPhone’s battery is its most delicate part, and good battery health is crucial for a wonderful user experience. However, it can easily get damaged and ruin the device’s overall performance. So, it is important to Maintain Your iPhone’s Battery Health by taking the necessary precautions.

If your iPhone 12 is not charging above 50 or 80 percent, it can be due to many reasons. For instance, a damaged cord, heated-up battery, high background activity, or poor battery health are all potential causes for a stuck battery percentage.

Let’s begin!

1. Ensure the Charging Port Is Clean.

Sometimes dirt or debris can get stuck in the charging port and result in various issues. Thus, it’s important to inspect it if you encounter any problem in your device related to its battery or charging.

Check your iPhone’s charging port for any signs of dirt or debris. Also, ensure that the bottom side of the device is completely clean. If not, remove the dirt particles using a cleaning solution and cotton swabs. It’s even better if you have dedicated instruments for this purpose. Then, connect the cable to the charging port to see if the issue is fixed.

2. Use Original Charging Accessories.

Charging your iPhone with fake or uncertified changing accessories can also lead to charging up only to a certain percentage. To avoid this issue, you must ensure that you are using MFI-certified charging accessories or have bought your charger from a genuine Apple store.

As much as possible, it’s best to keep using the original charger that was shipped within the box, as it is authentic and eliminates any risk of damaging the iPhone’s battery.

3. Ensure the Lightning Cable Isn’t Damaged.

Another factor that can lead to your iPhone not charging above 50 or 80 percent is a faulty charging cable. So, check the lightning cable and adapter as they may get bent or damaged over time.

Ensure you are using undamaged charging accessories. You can also confirm this by using the lightning cable on other devices or using a different charging cable and see if that fixes the issue.

4. Disable Optimized Battery Charging

One of the most common reasons your iPhone isn’t charging above 50 or 80 percent is that the Optimized Battery Charging option is enabled. This is a recent feature that takes into account the fact that Lithium-ion batteries should not be charged or discharged completely.

For this reason, every time your iPhone charges up to 80 percent, it automatically delays charging. The feature is beneficial and prevents batteries from wearing out faster. However, some users may find it unnecessary and would rather keep it disabled.

Here’s how to do it:

  1. First, launch the Settings app on your phone.
  2. Scroll down and go to Battery.

  1. Then, select Battery Health.

5. Change Charging Location.

For your iPhone to charge properly, it must be placed in a cool environment. If your iPhone’s battery is not charging past 50 or 80 percent, it may be due to an overheated surrounding.

Make sure to place your iPhone far from other electronic or heat-producing devices while it’s charging. If the issue still persists, change your iPhone’s charging location to a more conductive environment.

6. Remove Your iPhone’s Case.

If your iPhone has a thick and bulky cover, its temperature will likely increase during charging. An overheated iPhone doesn’t charge properly, so it might be the reason your device is not charging above a certain point. Try removing the case so that the heat can quickly dissipate off when charging.

As mentioned, an overheated iPhone can cause severe damage to its battery health. At extreme events, it can even result in an explosion. Avoid using your iPhone during charging to prevent high temperatures and potentially damage its battery. Also, keep your iPhone away from direct sunlight, and don’t overclock it.
