Why is my phone charging stacking at 85 percent?

The phone charging problem you’re experiencing may be a deliberate measure by the phone manufacturer. Modern smartphones come equipped with various software features designed to prolong battery life by preventing overcharging. One such feature stops the phone from charging past a certain point, like 85 percent. This is done to reduce the wear and tear on the battery caused by charging cycles.

First, verify if there is a Battery Health feature on your phone. Navigate to Settings, find Battery, and check if there are options for battery optimization or battery health management. Different devices have varying settings, so it might take a bit of exploration.

If no such setting exists, it might be a firmware issue. Ensure your phone’s software is up to date. Sometimes, manufacturers roll out updates that can inadvertently introduce or fix issues you’re describing.

Is the issue new, or has it been happening for a while? If it’s a recent development, think about any new apps you’ve installed or settings changes you’ve made. Sometimes apps can cause unforeseen conflicts. Try uninstalling any recent apps to see if the issue resolves.

Battery calibration could also be useful. Fully discharge your phone until it shuts off on its own, and then charge it uninterrupted to 100 percent. Perform this cycle once or twice to see if it makes any difference.

Lastly, don’t overlook the physical aspects. Inspect the charging cable and port. Sometimes lint or debris can interfere with proper charging. Use a small flashlight to inspect the port, and if necessary, gently clean it using a toothpick or soft brush.

I recently faced a similar issue and discovered it was related to the phone’s thermal management. When the phone detects it’s getting too hot, it might halt charging to prevent further heating, and it often happens around 85 percent. This can be exacerbated by environmental factors like charging in a hot room or using the phone heavily while charging.

Here are a few things you can do:
– Ensure you charge your phone in a cool place.
– Avoid using resource-intensive apps (like gaming or video streaming) while charging.
– Remove any thick or non-ventilating phone cases.

Another aspect to consider is the charger itself. Make sure you’re using the original charger that came with the phone or a high-quality third-party charger that meets the specifications needed by your device. Sometimes using a lower quality or incompatible charger might lead to abrupt charging stops to protect the battery from potential damage.

Lastly, if these steps don’t resolve the issue, try a factory reset. It’s a bit drastic, but software glitches can sometimes cause these problems. Just make sure to back up your data before performing a reset.

Operating systems and in-built safety mechanisms provide these interruptions to avoid overcharging, overheating, and extending the lifespan of the battery.

Your problem might originate from the Battery Health Management feature that modern smartphones incorporate. Manufacturers like Apple and Samsung introduce these features to enhance long-term battery health by preventing full charges all the time, which can degrade the battery faster. Here’s how you can check if this is the cause on both iOS and Android:

For iPhone:
1. Open Settings.
2. Scroll down and select Battery.
3. Tap on Battery Health.
4. Look for ‘Optimized Battery Charging’ and turn it off if it’s enabled.

For Android:
1. Go to Settings.
2. Navigate to Battery or Battery Health.
3. Look for an option similar to ‘Battery Optimization’ or ‘Adaptive Charging’.
4. Disable this setting to see if it allows your phone to charge beyond 85 percent.

If these setting tweaks don’t help, consider checking for any firmware updates. Manufacturers continuously roll out updates to fix bugs, including battery-related issues.

Additionally, clearing the cache partition could resolve system glitches causing this problem. Here’s how you can do it on Android:
1. Turn off your phone.
2. Press and hold the volume up button and the power button simultaneously until the device logo appears.
3. Use the volume buttons to navigate to ‘Wipe Cache Partition’ and select it using the power button.
4. Confirm the process and once done, reboot your phone.

For iPhones, a simple hard reset can sometimes clear up unusual behaviors. Here’s the quick way to do it:
1. Quickly press and release the volume up button.
2. Quickly press and release the volume down button.
3. Press and hold the side button until the Apple logo appears.

Battery degradation is another possibility. Lithium-ion batteries lose their capacity to hold a full charge over time due to regular cycles of charging and discharging. If your phone is a few years old, your battery might simply be aging and unable to accept a full charge. In that case, visiting an authorized service center to get the battery evaluated and potentially replaced would be the best course of action.

It sounds like your phone’s battery optimization settings may be causing this. Some phones have a feature that limits charging to 85 percent to extend battery lifespan. In your phone’s settings, look for ‘Battery’ or ‘Battery Health’ options. Check if there is an adaptive or optimized battery setting enabled. This feature monitors your charging patterns and stops charging beyond a certain percentage to protect the battery. You can disable this feature, if you prefer, to allow your phone to charge to 100 percent.
