Solving Battery Drain Issues Post iOS 12.4 Update

After updating your iPhone to the latest iOS 12.4, you may encounter a sudden drop in battery life. This is a common issue that occurs when the operating system re-indexes files after an update, causing the processor to work overtime and leading to increased battery consumption. This process can take anywhere from a few hours to several days, depending on the amount of data stored on your device. Once the re-indexing is complete, your battery life should return to normal.

Wait for the Re-indexing Process to Complete

Thankfully, there is no need to panic. A simple solution involves waiting for the re-indexing process to finish. Usually, this takes around 2-3 days. During this time, your device's battery consumption may increase slightly, but it will eventually normalize. If you continue experiencing battery drain issues after this period, you can try the following steps.

Optimize Your iPhone's Battery Performance

Here are some practical tips to help improve your iPhone's battery life: Close unused apps to reduce background activity. Dim the screen brightness to a comfortable level. Turn off Bluetooth and Wi-Fi when not in use. Suffice the use of cellular data during low-battery situations. Enable Low Power Mode to extend battery life.

Resetting Your Device

If the battery drain issues persist even after waiting and optimizing, you may need to reset your device. Here’s how you can do it:

Go to Settings General Reset Erase All Content and Settings. This option will restore your device to its factory settings but will erase all data. Make sure to have a recent backed-up copy before proceeding. Alternatively, you can try resetting your device to factory settings without erasing data. Go to Settings General Reset Reset_ALL_Except_Purch.'s. This will restore the iOS and apps but keep your data intact.

Restoring from backup or reinstalling iOS can sometimes resolve the issue. Choose the method that best suits your situation.

Battery Calibration

If you're experiencing battery drain issues on other devices like your Kindle, you may want to consider calibrating the battery. Here are the steps to follow:

Discharge your device fully until it turns itself off. Turn it on again and let it turn itself off. Plug your device into a charger and wait until the on-screen or LED indicator shows 100 percent. Unplug the charger and let your device turn itself off again. Turn your device on and charge it to 100 percent without interruption. Repeat this cycle until the battery percentage is reset. Discharge your battery fully and let it turn itself off. Recharge your battery to 100 percent without interruption and you should have calibrated the Android system's battery percentage.

Remember, regular battery calibration is crucial for maintaining optimal battery performance. For specific issues with Kindle devices, you can chat with a technician by dialing 1-844-761-1993.

Conclusion

Solving battery drain issues post iOS 12.4 update can be a simple process for most users. By understanding the re-indexing process and trying some basic optimization and calibration steps, you should be able to restore your iPhone's battery to its former glory. If the problem persists, seeking advanced solutions like device resets or contacting technical support can help resolve the issue.
