Have you been waiting for your iPhone XR to get fully charged before leaving the house, but it just won’t charge past 80%? You’ve switched chargers, changed USB cables, rebooted the device, but it’s still stuck at 80%? Well, the good news is that your iPhone is not faulty; neither is its battery. In this article, we’ll explain why your iPhone XR sometimes doesn’t charge past 80% and how To fix the issue.
We do almost everything on our smartphones these days; it’s our daily companion. Therefore, the importance of a phone with a long-lasting battery cannot be overstated. A phone that charges fast is even way better. So it’s understandable how frustrated you might be that your iPhone XR won’t charge past 80 percent. We explain why that happens and how you can get it fixed.
Reasons why your iPhone XR stops charging after 80%
1. Your iPhone is too warm
Your iPhone XR can stop charging if it exceeds a certain temperature threshold. If you’ve been playing CPU intensive games or if your iPhone is exposed to sunlight for a long time and then put on charge, or if you’re charging your iPhone in a particularly warm location, it will automatically stop charging past 80%. iOS will mitigate the problem by not allowing your phone to charge after 80%, as it will put the battery at risk.
2. Optimized Battery Charging
To avoid overstressing of the battery and extend its lifespan, the Cupertino-based company introduced the Optimized Battery Charging feature in the iOS 13. If the iPhone’s battery gets too warm during charging, the iOS might limit charging above 80% to slow down the process of battery aging. This is the reason why sometimes your iPhone gets charged all the way and then suddenly stops at 80 percent. The optimized battery charging feature is turned ON by default when you
set up your iPhone or update any iPhone to iOS 14.
How to fix iPhone XR not charging after 80% issue?
1. Cool Down your iPhone
If your iPhone gets too warm, you can follow the steps mentioned below to cool it down:
Turn your iPhone 12 OFF
Unplug it from the power source
Take off the case
Put it to a cooler place
Please note, whenever you’re trying to cool down your iPhone, never blast cooled air at your iPhone. Also, some people might advise you to put your iPhone inside a freezer or a fridge to cool it down, but make sure you never give it a try. This is because sudden changes in the temperature can cause condensation that might damage or even destroy your iPhone.
If the problem still persists, make sure to check our detailed troubleshooting steps on how to cool down an iPhone.
2. Turn OFF “Optimized Battery Charging”
If your iPhone is running iOS 14, the Optimized Battery Charging feature is turned on by default. Although this feature helps to extend the lifespan of the battery, it can prevent your iPhone XR from charging past 80% at certain times. Therefore, you can disable this feature to check if the charging continues up to 100 percent or not.
Follow the steps below to turn off Optimized Battery Charging on iPhone XR:
Go to Settings > Battery
Tap Battery Health
Turn off the switch next to Optimized Battery Charging
If you are still facing iPhone XR not charging issue after turning off this feature, you can turn it ON and allow it to extend the lifespan of the battery.
iPhone XR not charging to 100%? Problem solved!
If your iPhone XR is not charging to 100%, you may notice that it remains at the 80% threshold or something close to that (like 83-84% for me). That’s because Apple introduced a new feature in iOS 13 called “Optimized Battery Charging.” This feature has the software preventing or delaying your device’s charging at 80% for as long as you aren’t using the device.
You may also find your iPhone XR battery not charging to 100% because of the battery temperature. When you overcharge your iPhone XR, it may generate a lot of heat, which is detrimental to battery health. The heat that your device generates while charging basically exerts extra stress on the battery, reducing its lifespan. Again, Optimized Battery Charging and iOS can limit charging beyond 80% if the battery temperature exceeds Apple’s recommended limits. While the Optimized Battery Charging feature is supposed to help you extend your battery’s life, maybe you want to turn it off to see if your iPhone XR can fully charge to 100%.
