Did you plug your iPhone charger the whole night, but the battery percentage is still at 80 percent in the morning?
A genuine question will be: Why won’t my iPhone charge past 80? Does my charger is dead, or iPhone battery is faulty?
Don’t worry! You’re not alone. Thousands of iPhone users face such issues, which can be resolved easily.
In most cases, iPhone users face this issue due to wrong settings or minor software glitches.
Apple also restricts charging batteries to 80% to increase the overall lifespan.
However, you can charge your iPhone 100 percent by overwriting the default settings.
In this guide, we’ll see the various reasons why an iPhone won’t charge past 80 and how we can fix it.
Why Won’t My iPhone Charge Past 80?
Apple introduced Optimised Battery Charging feature in iOS 13 to slow the charging speed above 60 percent and even stop the charging post 80.
Charging the battery 100 percent might put extra strain on the iPhone battery and degrade its health in the long run.
That’s why Apple recommends charging the iPhone 80 percent only. This helps in increasing the overall battery health.
Also, if you are charging your iPhone wirelessly, it heats up. High temperature is not good for Li-ion batteries.
Hence Apple stops charging at 80 percent to save battery health.
Another major reason iPhone won’t charge fully is a faulty or damaged battery.
So, if your iPhone is more than two years old, then check its battery health from the settings and replace the battery if battery health is below 70.
How To Charge an iPhone to 100 Percent?
Despite the battery health concerns, some people want to charge their iPhones 100 percent when traveling somewhere.
Fortunately, it is possible to do so by overwriting the default settings in iOS 13 and some other tips.
Here’s how you can charge your iPhone 100 percent:
Method #1- Turn Off Optimised Battery Charging
If your iPhone battery is not charging past 80, then the first thing you should do is- turn off the “Optimised Battery Charging” feature from the phone settings.
Follow these steps to disable the optimized battery charging option in iOS 15 or later-
- Go to Settings of your iPhone.
- Scroll down and tap on Battery.
- Tap on Battery Health.
- Toggle off the Optimised Battery Charging option.
- Tap on Turn Off Until Tomorrow or Turn Off permanently.
Method #2- Cool Down Your iPhone
If you’ve disabled the Optimised Battery Charging from the Settings, but your iPhone still won’t charge past 80, then there is a possibility that your phone is hot.
Apple continuously monitors the condition of iPhones and pushes regular iOS updates to fix the heating issues.
It heats your phone if you’re doing graphics-oriented tasks on your iPhone on hot sunny days.
Now, when you connect your lightning cable to your iPhone, it simply won’t charge.
To fix this, you need to wait for your iPhone to cool down and then try charging it.
You can also power off your iPhone and leave it below the air conditioner to cool down quickly.
Method #3- Use Original Lightning Cable & Adapter
If the heating issue is not resolved and your iPhone still won’t charge past 80, then there might be a problem with your charger or lighting cable. Try using another original Apple charger or cable and see if it works.
Method #4- Use Another Power Source
Also, you can charge your iPhone with MacBook. Connect your iPhone to the MacBook with a lighting cable, and then keep it charging until 100 percent.
This is an ideal way to charge your iPhone if you’re traveling and don’t have access to wall chargers.
Method #5- Update iOS
An outdated iOS version might also be a reason why your iPhone is not charging fully.
Go to Settings -> General -> Software Update and see if an iOS update is available.
If yes, install the updates and then try charging your iPhone to 100 percent.
Method #6- Factory Reset Your iPhone
Did you know that a factory reset can also help in fixing iPhone won’t charge issues? It will also fix many software-related issues.
A factory reset will delete all the data stored on your iPhone and restore it to its original condition.
To factory reset your iPhone, go to Settings -> General -> Reset -> Erase All Content and Settings and enter the lock screen password to perform the reset.
