Heat generation is an unwanted but normal side effect of charging your phone, but up to a point: If your mobile charger gets too hot when it’s working, then you’d better take action. because overheating can be dangerous. Here are the main reasons why your charger overheats.
The charger is not compatible with your phone
Using a charger that is not designed for your phone may cause the charger to become hot. The key is that chargers built specifically for the electrical specifications of your phone and its battery are programmed to provide just the right amount of power, something that doesn’t happen with others.
Thus, if you use a charger whose output power is lower than that of your phone, it will cause your phone to overcharge, causing work harder to provide enough power to the device. Be careful because if it does not cool down, it can overheat so much that it burns, causing a fire.

One of the effects of fast charging (beyond the obvious that the battery is full sooner) is that more heat is generated than with a normal charger. To keep this extra heat at bay, some manufacturers implement cooling and power management features built into the device itself.
If you are using an ultra fast charger, it will likely get hot and shouldn’t be a problem. Of course, it is better to avoid more heat, so it is recommended in direct sunlight or place it on surfaces that do not dissipate it well (such as the sofa).
you are in a hot environment
Although it is obvious, it is worth remembering that if you are charging your phone in direct sunlight or inside a hot carlogically it is easier for the charger to overheat.
If we take into account that the charging process itself generates heat and we add it to what is already in the environment, the result can be damage internal charger componentswhich causes overheating and short circuits.
The charger is faulty
A charger getting too hot can also be caused by some of the internal components are not working properly. Thus, if some piece of equipment cannot deal with the power or voltage it receives from the socket, it overheats as a result.
This can be simply and simply due to deterioration from use (be careful not to move it too much or bend the cable), to low-quality components or to those that do not have the relevant safety checks and consequent quality certificates. Buying a counterfeit or imitation charger It does not imply that it is going to heat up, but it does mean that you have more ballots for it to happen.
A problematic ruler

Perhaps what is giving problems that cause overheating is not the charger, but the power strip it is plugged into. Be careful, connecting a charger to a power strip does not necessarily imply overheating, but if it does not work properly it can be one of the consequences.
It must be taken into account that the strips have a maximum operating powerso if you have multiple devices connected and they exceed the recommended design values, the result can be overheating and even damage to the connected devices.
Your phone is faulty
If you have ruled out all of the abovethen assess that perhaps the problem is with the phone and you have to take it to support.
When certain components of your phone are damaged, one of the consequences may be that the charger overheats. Although it is the main suspect, the battery is not the only “culprit”. Thus, it can be about more general hardware or even the software of the phone. When the phone is defective, it can draw more power from the charger, which would generate that extra heat.
How to keep the temperature of your phone charger at bay
If you want to minimize the overheating of your phone charger, here are some good practices and recommendations:
- Use specific chargers for your phone. The original and official chargers are a guarantee of total compatibility, but if this is not the case, it is better to bet on those that are compatible and from well-known manufacturers. If your phone is an iPhone, with MFi you make sure that Apple has approved the accessory.
- Whenever possible, charge your phone on a cool and ventilated area.
- If you are going to use a rulerthat it is one with the relevant quality and safety certificates and that it is not cluttered with other connected devices.
- Better not charge your phone overnight or for many hours. Overcharging your device causes it to heat up and can speed up the deterioration of components.
- If you are not charging your phone right nowunplug the charger from the outlet, which minimizes the risk of overheating and possible damage.
- Avoid moving or bending the cables that you connect to the charger. A good way to do this is to not use the phone while you are charging it.
- If you detect that your charger is getting hotter than normal on a regular basis, it is a good sign to stop using it and renew it.
