Your iPhone won't charge beyond 80%: What to Do Now let's explore some of the main causes and solutions of why your iPhone stops charging sometimes around 80% and why you may experience issues charging fully on some occasions.
Optimized Battery Charging Is Enabled
Once activated, "Optimized battery charging" may cause your iPhone to stop charging at around 80%. This feature uses your daily charging habits to reduce battery aging; once enabled, this feature won't charge beyond this threshold under certain conditions.
If you charge your phone every night, it will stay between 80% and 100% most of the time, then jump up to 100% upon awakening. Your battery will experience less time spent charging at high levels and perform better overall.
Introduced with iOS 13, "Optimized battery charging" aims to prolong battery life by decreasing energy usage from apps you aren't actively using and managing performance according to habits and usage patterns; for example, battery optimization might limit background activity if battery power drops too low.
Solution: To disable the Optimized Charging Battery feature, navigate to "Settings", "Battery", and then "Battery Health & Charging", before toggling off "Optimized Charging." To address any potential problems caused by it.
Charge Limits for iPhone 15 Models
If you set your iPhone 15 model or later to 80% charge limit, it will not charge any further. This Charging Limit actually helps prolong the battery life of your iPhone.
You can adjust the charge to 85% or 95% if you have an iPhone 15 running an older version iOS. Even if you set your charge limit to 100 percent, Optimized battery charging may still keep the charge at 80%. It will continue charging slower after 80 percent and finish charging only shortly before you use your phone.
There are other possible reasons why your iPhone is stuck on 80
There could be other factors involved if disabling the Optimized battery charging doesn't fix the problem.
iPhone Battery Protection
If the iPhone battery becomes overheated while charging, charging will be limited to 80% to prevent damage to both itself and to prolong its battery life. Once temperatures return to normal, charging can resume normally.
Solution: For optimal performance, utilize a lower wattage charging cable or place your iPhone in an air-conditioned environment to prevent it from overheating.
Solution: Plug your charger into another power outlet or USB to identify potential power source issues and then clean its port with soft bristle brush or compressed air to restore proper functioning..
Hardware Issues
A defective or aging battery can prevent your phone from charging past 80%. Damaged or non-certified cables can also cause charging to be incomplete.
Solution: To prevent this, use only genuine charging accessories or those certified by MFi. You may also want to consider replacing your battery if you notice signs of wear.
Software Issues
A software bug can sometimes prevent your iPhone charging beyond 80%.
Solution: A quick restart can solve charging problems. Press and hold the power key until you see the "slide off power" slider. Wait a few moments, then turn your iPhone back on.
Be sure that your iPhone has the latest version of iOS. Navigating to Settings >General >Software Update and updating iOS are among the steps..

4. Is Android Battery Charging Optimized?
Android devices do offer battery-charging features such as Adaptive Battery and Adaptive Charge. These technologies adapt charging patterns based on user habits. They aim to increase battery life by reducing overcharging, excessive heat and wear.
5. How many cycles will it take for your iPhone to lose its battery?
iPhone batteries can maintain 80% of original capacity even after many complete charging cycles. This threshold is 500 complete charge cycles for iPhone 14 and older models. This threshold has been raised to 1,000 full charges cycles for iPhone 15 and newer models.
Doing it right doesn't need to happen all at once; one complete charge cycle occurs when 100% of battery capacity has been consumed, such as when you charge and use your battery again the following day after using 50%. This would constitute one full cycle.
