Why Do Phones Get Hot When Charging?

Using your phone while charging can increase your phone’s overall power by heating it up, thereby shortening your phone’s battery life. If your phone is charging while playing, it may overheat and reduce battery performance. In case you were wondering, yes, using your phone while charging generates more heat.

Phones get hot when charging because electricity generates heat. When electrons move from an outlet into a phone, the movement produces friction. This friction is felt as heat, and the phone feels hot as a result of the friction made by electrons. This is normal and is rarely a problem for the device.

Many devices only support the first 50% of fast charging and actually warn you that fast charging will generate additional heat. Slower charging rates require longer charging times, which can cause the phone to heat up for extended periods of time, which can damage the phone’s battery. Charging issues are also a factor in overheating your phone. When the phone is placed on the charging pad, the large power loss further translates into heat build-up that can damage the battery over time.

Why Your Phone Is Overheating

Your device is overheating because you are consuming and charging your battery at the same time. Charging occurs because the phone is not using the battery or because the app is not running in the background when the phone is turned off. There may be times when you use the same cable and charger for your device as before, but now your phone is starting to overheat. Your device may be overheating or overheating due to apps running in the background or you may be using your phone while it is charging.

If you charge your device before bed, you need to know that overcharging your phone can also damage the battery and cause overheating issues. Another factor that we most often overlook that leads to a phone overheating while charging is overcharging the phone. If the charger is causing overheating, a new charger or charging cable must be purchased. Since charging your phone causes the device to overheat, you must also unplug the charging cable while charging.

If the charger is of poor quality or of the required quality with a charging cable, the phone heats up from the bottom of the phone or where the exit from the charging connector is. If your iPhone is in the wrong place, the phone and charger collide, causing the phone and charger to generate excessive heat without actually charging the device. Charging your phone generates heat in the power source, heat in the phone’s charging circuit, and heat when power is supplied to the battery.

The Movement of Electrons Generates Heat

In fact, when you charge a mobile phone or any other electronic device, there will inevitably be some heat that will be radiated from the charger or from the connected device. On a hot day, the heat radiated from a charging phone can rise to dangerous levels if not allowed to dissipate effectively. One possible reason why your phone is heating up is because it has been exposed to direct sunlight or another heat source for too long. Your phone may get warm while charging due to one or a combination of these factors.

If your phone is overheating while charging, you may be using a fake charger or there may be a problem with the battery. If you notice that your phone gets warm during or shortly after charging, a faulty charger may be the cause. If you find that your Android won’t charge and the charger and cable work fine while other devices charge without issue, your phone’s battery may be the problem. It’s possible the charging circuitry is the problem, but if the iPhone has power, it’s likely that the battery is there.

Using iPhone 12 while charging causes the battery to overheat and may damage it. The more you use your phone, the slower it charges, the longer it stays connected, and the warmer it gets. When you charge your device, you can turn off your device or put it into Airplane Mode as it will charge faster than when it is on. For example, you can charge your phone to 40%, then unplug it, or stop charging for 10 minutes and charge it back up to full battery.

Tips for Keeping a Phone Cool

If your phone gets warm while charging, you can increase these charging intervals, for example, the first interval to 30% and the second to 60%, after which you can fully charge the phone’s battery with or without a third interval. You should avoid using a phone case or cases while charging, especially on hot summer days or in hot or very hot conditions, or if the phone is constantly overheating. To keep your phone cool, be sure to use the charger and USB cable that came with your phone model.

To prolong battery life and keep the internal parts of your phone safe, you should avoid overheating your phone while using or charging. This is why fast charging in most cases should be adjusted by the phone to reduce battery damage and overheating. Using a charging adapter not designed for your device may result in higher power output than for your phone, and this may result in even more internal overheating.

All you can do to minimize the effect of overheating when using certain apps is to avoid using your device while charging. Placing the phone in a high temperature environment promotes discharging, which can lead to overheating as the phone’s system tries to find a balance between charging and discharging. A faulty charger or charging cable can cause low voltage to be transmitted in the phone’s battery and circuits.
