Always On Display is kept disabled and CPU speed is limited. Also, apps in the background stop using Wi-fi or mobile data.
We will have to enter Settings / Battery and inside, we can see the different saving modes to make the battery last longer. If we are not satisfied with autonomy, we should try the following solutions. It does not matter if the mobile is new or has a time, since overnight, its autonomy may start to be much less than usual, without being able to find an apparent explanation. It is another of the most common problems. To check it, we must restart the mobile, to check if the battery no longer heats up. Sometimes, battery heating problems can be caused by an application that has been “stuck” in the background, consuming resources and energy permanently. To solve this, we can clean the chargers often, or buy dust caps for the charging port, which work very well.
This will create a risk of overheating due to corrosion or a temporary short circuit of the port socket. It is very important to prevent dust, sand or dirt from entering the slot of the charger. We will have to test with an original accessory to see if the problem disappears, since many heating problems are a problem of generic accessories of dubious quality. The use of a third-party adapter or cable may cause performance problems, failure or damage, which will also not be covered by the warranty. It is important to use only Samsung chargers, batteries and cables. This recommendation is made by us, made by Samsung and made by any manufacturer.
If we do it, not only can the battery heat up, but we can also damage the charging device. The most important thing is not to place RFID cards (radio frequency identification cards), credit cards or smart lock cards between the device and the back of the charger. If we use a wireless charger, we will not have to place objects such as magnetic stripe cards, magnets or metallic objects between the device and the wireless charger. If we are using a traditional charger, it is not recommended to use the mobile while it is in the process of charging, since the temperature will increase excessively. Ideally, turn it off and let it rest until it cools down and returns to its normal temperature. This and similar cases will cause the battery to overheat, which is not beneficial and will hamper performance. It may be that we have been playing for a long time, or that we are using the GPS in the car and the sun is affecting our mobile. We will also note that the running apps will be closed and only the emergency calls feature will be available until the phone cools down. In addition, the brightness of the screen and the speed of the device automatically decrease to reduce the temperature of the device, as a security measure. As Samsung itself explains, if the temperature rises too much, it can slow down the device’s charging speed or even slow down. Sometimes it can be a security measure, but in others we will have to be very careful, since it could be damaged or cause damage to our mobile. That the mobile gets hot is one of the most common causes and possibly the first to arise when something begins to go wrong.
