Have you been waiting for your iPhone to be fully charged before leaving the house, but it doesn’t go past 80%? Have you changed chargers, changed USB cables, rebooted the device but still stuck at 80%? The good news is that your iPhone is not malfunctioning; not the battery. Below we will explain why your iPhone sometimes does not exceed 80%.
We do almost everything on our smartphones these days; he is our everyday friend. Therefore, the importance of a phone with a long-lasting battery cannot be underestimated. A fast charging phone is much better. So it’s understandable how frustrated you might be that your iPhone isn’t exceeding a certain percentage. We explain why this happens and how you can fix it.
Why Doesn’t Your iPhone Go Over 80%?
There are two known reasons why this happens.
1. Optimized Battery Charge
The main reason why your battery won’t charge above 80% is because your phone doesn’t allow it. Yes, you read it right. Your iPhone’s battery is not faulty; neither the phone is broken or anything else. But why?
The agent responsible for your iPhone not charging above 80% is known as ‘Optimized Battery Charge’. This was one of the many features introduced in iOS 13. The ‘Optimized Battery Charge’ feature delays your phone’s battery charge by 80% unless you are using your device.
According to Apple, this feature is designed to use machine learning to examine your daily usage and charging routine, so it can limit the charge to 80% until you need to use your device. For context, let’s say you use your iPhone between 10:00 am and 10:00 pm every day, your device notes it. Therefore, when you plug your iPhone into charge at any time outside of your normal usage time, the charge level may not go above 80% charge.
Benefits of Optimized Battery Charging
One of the many mistakes that can shorten your iPhone battery life is constantly charging the device to 100%. Research has shown that leaving your phone between 30-80% helps you get the most out of your phone’s power backup, especially Lithium-Ion batteries. Constantly charging your iPhone to 100% will wear down the battery over time and shorten its lifespan faster.
iOS 13 ‘Optimized Battery Charge’ prevents this by stopping charging on your iPhone when the battery reaches 80%. As your normal phone usage hours (determined by the iOS 13 machine learning algorithm) approach, charging continues slowly until the battery mark reaches 100%. This helps extend the battery life of your iPhone and iPad and prevent your device from draining too quickly.
2. Battery Temperature
Overcharging your iPhone produces excessive heat, which is harmful to battery health. The heat generated during charging puts pressure on your device’s battery and greatly reduces its lifespan.
Fortunately, iOS 13 is smart enough to limit the charge to 80% if it detects that your battery temperature has exceeded the recommended level (set by Apple). So, if your iPhone does not exceed 80%, it may be because your battery temperature exceeded the set limit.
Charge Your Phone More Than 80%
Need to quickly charge your phone to over 80%? Check the methods below.
1. Disable Optimized Battery Charge
The Optimized Battery Charging feature puts the health of your iPhone’s battery above your smartphone’s needs. And that makes sense. Before proceeding with disabling the feature, you should know that Optimized Battery Charge will eventually charge your phone to over 80%, but only when you need to use your phone.
If you can’t wait and want your phone’s battery to charge over 80% immediately, follow the steps below to disable Optimized Battery Charging on your iPhone.
Note: Optimized Battery Charging is enabled by default and only active when your iPhone anticipates it will be connected to the charger for an extended period of time.
Stage 1: Launch your iPhone’s Settings menu.
Step 2: Choose Battery.
Stage 3: Tap Battery Health.
Step 4: Tap ‘Optimized Battery Charging’ to turn it off.
Step 5: You can choose ‘Turn Off By Tomorrow’ to temporarily disable the feature until the next day, or ‘Turn Off’ to permanently disable the feature until you manually re-enable it.
Now your iPhone will occasionally charge at 80% without being stuck.
2. Change Charging Location
As mentioned earlier, your iPhone battery may be stuck at 80% if it gets too hot during charging. If you’ve disabled ‘Optimized Battery Charging’ but your iPhone still doesn’t exceed 80%, you’ll want to make sure the charging environment is conducive enough. You should charge your iPhone in a cool, well-ventilated environment. You also want to avoid charging your iPhone near other devices, electronics, or devices that produce heat.
3. Remove Phone Case
Do you have a phone case attached to your iPhone? If you notice that your phone will not charge above 80%, you should remove it. Smartphones heat up to some extent while charging, and phone cases (especially thick and bulky ones) can raise the temperature of your phone and battery by preventing the heat from escaping into the atmosphere.
4. Use Original Charging Accessories
Using fake/unauthorized/third-party charging accessories can also cause your iPhone to stop charging when it reaches a certain percentage. Make sure you charge your device with out-of-the-box or Apple MFI certified charging accessories. Also, be sure to purchase and use a charger from an authorized store that sells original accessories.
Some iPhone users have managed to get their devices charged above 80% by dropping third-party charging accessories for the original charging accessories. You should do the same.
Extend the Life of Your Battery
The more you charge your phone to 100%, the less power your battery can hold over time. Although very basic, not many people know about the Optimized Battery Charging feature. Now that you are aware of it, we hope you will get used to this feature and stop worrying about your iPhone when it does not exceed 80% or charges slowly beyond this threshold.
