How to Fix ‘Phone Stops Charging at 80% or 85%’ on Android

There could be various reasons why an Android phone or tablet doesn’t charge while plugged into a power supply. However, if a device stops charging after reaching the 80 or 85% limit, it could be due to the battery protection feature. By turning off the Adaptive Charging, Protect Battery, or Battery Protection feature on your Samsung phone or Galaxy Tab, you can fix the ‘phone stops charging at 80% or 85%’ problem. Follow the steps in this article to disable this feature from device settings.

Most smartphone manufacturers use charging technologies like PPS (Programmable Power Supply), PD (Power Delivery), and QC (Quick Charge). Samsung Galaxy S20 was the first phone certified for PPS fast charging. PPS allows current and voltage to be adjusted stepwise. It reduces conversion losses to ensure more efficient charging. PPS fast charging is better for Lithium-ion batteries because it produces less heat, and less heat increases the battery’s lifespan.

What’s the Battery Protection Feature?

The Battery Protection feature is a part of the PPS charging protocol that programs how a smartphone or tablet charges. So why does your Android phone stop charging at 80 or 85%? The simple answer is that it’s a feature designed to protect the battery from overcharging. Lithium-ion batteries can be damaged if continuously charged after reaching their full capacity. Therefore, smartphone manufacturers have implemented a safety mechanism that automatically stops charging once the battery reaches around 80-90%.

This feature prevents overcharging and helps prolong the overall battery lifespan. It ensures that the battery retains its maximum capacity for as long as possible and avoids premature degradation. However, this feature can also cause frustration for some users who may think there’s something wrong with their phone or charger when it stops charging at 80%. They may try different chargers or even replace their battery but still face the same issue.

The battery charging behavior may vary among different Android phone models and brands. Some devices may stop charging at 80%, while others may continue till 85% or even higher. For example, Samsung One UI 6 phones stop charging at 85% while One UI 6.1 devices stop at 80%. Also, if your phone gets too hot while charging, it may stop at a lower percentage to prevent overheating and potential damage to the battery.

The issue of Android phones stopping at 80% charge is not a malfunction or defect but rather a safety feature implemented by OEMs. It is designed to protect your phone’s battery and ensure its longevity. You can follow our tips to extend the battery life on your Samsung phone.
