Many people have reported that their iPhone 12 mini stop charging after 80. If you’ve found yourself in a situation like this, don’t worry! While frustrating, this problem is usually pretty easy to fix. In this article, we’ll cover the most common reasons why your iPhone 12 mini stops charging at 80%, and give you some solutions on how to fix the issue.
Why Does My iPhone 12 mini Stop Charging At 80%?
Aside from a cracked screen, issues with charging are the most common problem that iPhone 12 mini users face. This is because the battery in your iPhone 12 mini – or any smartphone, for that matter – is one of the few components that naturally degrades over time.
As a result, there is a multitude of reasons your iPhone 12 mini might stop charging at 80% (or even worse, stop charging altogether).
Here are some of the most common reasons that your iPhone 12 mini battery isn’t charging past 80%.
Your iPhone Battery is Self-Preserving
If you find your iPhone 12 mini not charging above 80 sometimes, it’s likely because of a feature that Apple implemented to improve your battery’s lifespan. Most of us try to keep our iPhone at 100% as much as possible, but as it turns out, this can actually be worse for your iPhone’s battery.
For one, being charged to 100% and holding a 100% charge is more strenuous on lithium batteries, wearing out their lifespan. Not to mention that charging your phone heats the battery, which also affects its overall lifespan.
To preserve the lifespan of your iPhone battery, Apple introduced a battery optimization feature in iOS 13 that slows down how quickly your iPhone charges and will even hold it at 80% to avoid overstressing the battery. That’s why your phone sometimes charges all the way, but other times gets stuck at 80%.
Your iPhone is Too Warm
Another common reason that your iPhone 12 mini stops charging is because of the temperature. As mentioned, heat is one of the quickest ways to damage and decrease your iPhone’s lifespan.
If you’re charging your iPhone in a particularly warm location, the iPhone 12 mini will automatically stop the battery from charging past 80%. Since charging your phone for long periods of time and keeping it in a warm environment both put your battery at risk, Apple will mitigate the problem by preventing your iPhone 12 mini from charging past 80%.
If you notice a correlation between your charging issues and the weather, this is probably the source of your charging woes.
Your iPhone or Its Charger Might be Damaged
And lastly, while unfortunate, the problem could be that your iPhone 12 mini or its charger is damaged or defective. If you’ve recently started using a new charger with your iPhone, there’s a pretty good chance that it’s the culprit.
Try switching between different chargers, cables, and wall outlets to determine the source of the issue. Make sure to clean the charging port on the bottom of your phone as well, as dust buildup can prevent it from charging properly.
If none of that works, then your iPhone 12 mini is most likely to blame. Luckily, resolving battery-related issues is usually pretty painless!
How To Fix An iPhone 12 mini That Won’t Charge Past 80%
Lower your iPhone Temperature
Because iPhones are made out of glass and aluminium, they can overheat pretty quickly, especially during the summer months. This happens most often when people are driving around with their iPhone on the charger, as sun rays coming through your windshield can cause your iPhone to overheat.
To see if this is the problem, try fixing your iPhone Overheating issue by turning it off, removing it from the charger, taking it out of direct sunlight, and moving it to a cooler location.
Turn off “Optimized Battery Charging”
iPhones comes with the Optimized Battery Charging feature enabled by default. This feature implements several techniques to extend your iPhone battery life.
One of the main ways that it does this is by preventing your iPhone 12 mini from charging past 80% at certain times. If you’d rather have your phone charge to 100%, though, you can easily turn this feature off in your battery settings. See this article if optimized Battery charging is not working.
Visit your local Apple store
If neither of the above steps seems to fix iPhone 12 mini not charging above 80 issue and you’ve determined that the issue is your Device – not a malfunctioning charger or cable – then you may need to take your iPhone 12 mini into an Apple authorized repair center to have it looked at or even replaced.
Apple will diagnose the charging issue for you free of charge, and – depending on the problem – might even offer to repair the issue for free! If your iPhone is less than a year old and already having battery issues, then you’re a pretty good candidate for having this issue resolved free of charge.
