iPhone Battery Problems? 10+ Proven Fixes for All Model [iPhone 17 Supported]

Part 1: iPhone Battery Draining Fast

One common iPhone battery problem is rapid battery drain. To fix this, you first need to identify what’s consuming your power. Go to Settings > Battery > Battery Usage and review which apps are using the most energy. If certain apps are draining too much, update them or uninstall the ones you don’t need. With the iPhone 17, Apple has enhanced battery optimization with the latest A‑series chip and smarter iOS background management. 

Furthermore, in order to resolve the iPhone 13 battery draining fast, you should turn off the background app feature. If it is turned on, then the essential apps on your phone would be refreshed automatically. To turn it off, go to Settings > General > Background App Refresh and toggle this feature off.

It is also observed in most cases that the location-based service on iPhone consumes a lot of battery. If you keep moving, then this feature can drain your device’s battery without even using it. Therefore, turn it off by visiting your phone’s privacy setting and switching off the “Location Services” option.

After following these simple solutions, you would be able to resolve the iPhone battery problems related to its fast drainage.

Part 2: iPhone Gets Hot While Charging

Another common iPhone battery problem is overheating, which many iOS users face. If your iPhone gets hot while charging, it could damage the battery over time. While it’s normal for devices to warm up slightly, persistent overheating or receiving temperature warnings should never be ignored. With the iPhone 17, Apple has introduced improved thermal management to reduce heat during charging and intensive tasks. However, even with these advancements, users may still encounter iPhone 17 overheating issues if they use incompatible chargers, play heavy games while charging, or expose the device to high temperatures. 

To start with, remove your phone from charging and let it cool down. Additionally, turn it off or restart your device. If your device is not able to turn off, then you can always force restart it. If you are using iPhone 6 or older generation devices, then long press the Home and Power button at the same time for at least 10 seconds. This will turn your device off.

If you are using an iPhone 7 or 7 Plus, then long press the Power and Volume Down button at the same time. Keep pressing both the buttons for at least 10 seconds to force restart it.

If you’re troubleshooting an iPhone battery problem, a force restart can often help. For the iPhone 11, iPhone 12, iPhone 13, iPhone 14, iPhone X, and newer models like the iPhone 17, the process is the same: quickly press and release the Volume Up button, then quickly press and release the Volume Down button, and finally press and hold the Side Button until the Apple logo appears.

Additionally, it is observed that after making your phone a hotspot, it consumes a lot of battery and produce an evident amount of heat. If you are charging your phone while making it a personal hotspot, then it might overheat it. To avoid this, go to your phone’s settings and turn off the feature of Personal Hotspot. This will resolve the iPhone 5 battery problems associated with overheating.

Part 3: iPhone Shuts Down with Battery Left

This might be a rare situation, but it is associated with quite a few iPhone battery problems. There are times when iPhone turns off out of the blue even when it has enough battery left. If your iPhone shuts down unexpectedly even when there is battery left on your device, then check its Date and Time feature. Go to your phone’s Settings > General > Date and Time and turn on the “Set Automatically” option.

This will ensure that your iPhone won’t turn off unexpectedly. Additionally, to resolve these iPhone 14/13 battery problems, you need to calibrate your device’s battery. In order to calibrate your phone, let its battery drain at first. Once its battery is drained, your phone would be turned off. After draining its battery entirely, connect it to a charger and in one go, charge it to 100%. Even when it is charged to 100%, turn your phone on and keep charging it for another 60-90 minutes. This will calibrate your phone’s battery and resolve the iPhone 14/13 battery problems.

Part 4: Abnormal Bad Battery Life after iOS 17/18/26 Update

Sometimes an unstable iOS update can trigger an iPhone battery problem, causing faster drain or unexpected glitches. If your device is running on a buggy software version, it may directly affect battery life. The simplest fix is to update your iPhone to the latest stable iOS release. For the iPhone 17, Apple has optimized iOS for improved battery health and efficiency, but early beta versions may still lead to temporary iPhone 17 battery issues. 

In order to fix the iOS 26 battery drain problems, you can choose to update your phone to a stable version. To do this, go to Settings > General > Software Update and check the stable version of iOS available. Tap on the “Install Now” button and wait for a while to update the device’s operating system.

Part 5: iPhone Slow Charging Issue

If your iPhone isn’t charging properly, it could be linked to hardware issues or a faulty cable, which may lead to an iPhone battery problem. Always check whether your Lightning cable is functioning correctly, and make sure to use only original, Apple‑certified accessories for safe and efficient charging.

Sometimes an iPhone battery problem can be linked to a faulty or dirty charging port. Inspect the port carefully, clean it with a soft cotton cloth, and ensure there’s no damage that could interfere with proper charging.

If there is a software-related issue with your phone, then it can be resolved by putting it into DFU mode. To do this, firstly turn off your phone. Now, press the Power and Home button at the same time for at least 10 seconds. Afterward, let go of the Power button while still holding the Home button. Make sure that you hold the Home button for another 5 seconds.

Your phone will enter into DFU mode and can be connected to iTunes/Finder in order to restore it. By implementing these steps, you would be able to resolve the iPhone battery problems that are related to its charging.
