After the launch of new 5G bands, many smartphone users are noticing one annoying problem. The phone starts heating up a lot while charging on 5G. Even if you are not using the phone much, the back panel feels warm and sometimes very hot. This issue is mostly seen after recent network changes and system updates.
Along with this, fast charging makes the situation worse. For now, this problem is not limited to one brand or one model. Many Android phones are facing it. The good part is that in most cases, this is not a serious hardware problem. It happens because of network behavior, charging style, and phone settings. In this article, we will see the real reasons for heating the phones and how we can fix them very simply.
Why does the Phone heat while charging on 5G
5G network is faster, but it also uses more power. After new 5G bands, your phone modem works harder to stay connected. It keeps searching, testing, and switching bands. This uses extra battery power. At the same time, charging already produces heat inside the phone.
When charging and 5G both work together, the heat increases quickly. Along with this, if the signal is weak, the phone struggles more and generates extra heat. That is why heating is higher indoors or in low signal areas. For now, this behavior is common with 5G and does not mean your phone is damaged.
New 5G Bands and Continuous Network Switching
After the new 5G bands rollout, many phones are still not fully optimized. The phone keeps switching between different 5G bands and sometimes between 4G and 5G. This switching happens silently in the background. You don’t see it, but the phone modem is working all the time.
This constant activity increases the temperature. While charging, this effect becomes stronger. Many users have noticed that when they lock their phone to 4G, heating reduces clearly. This shows that network switching is one of the biggest reasons behind heating after the new 5G bands.
Fast Charging Makes Heating Worse
Fast charging is useful, but it is not always good for temperature control. Fast chargers push high power into the battery in a short time. This creates heat naturally. Now, when fast charging and 5G are active together, the phone handles two heavy tasks at once.
This leads to overheating. Along with this, using non-original chargers or cheap cables makes things worse. Poor quality chargers waste power, and that wasted power turns into heat. For now, try using a normal or slower charger when you are on 5G. Charging will take more time, but heating will be reduced a lot.
Background Applications Add Unnecessary Load
There are numerous applications running in the background that you are not aware of. The Internet is also being consumed by apps such as social media, emails, cloud backup, and location services. These apps in 5G use more power since the data speed is fast.
In addition to this, there are still apps that are not optimized for 5G networks. This increases CPU usage. Heat is generated quickly when there is a combination of CPU, modem, and battery. To begin with, in the meantime, prior to charging, close unneeded applications. Turn off auto-sync, also, at least temporarily. Such minor measures lower the background load and are used to regulate heating.
Weak Signal Areas Are More Heating Causing
Your phone strains more, in case you are in a place with a low 5G signal. It makes an attempt to retain the connection by consuming more power. This causes more heat. Most of those who use it observe a lot of heating in buildings, lifts, or closed rooms. In conjunction with this, the temperature rises rapidly in such areas because of the charging.
In the meantime, when the signal is low, prefer to use 4G in the process of charging up. 4G is more reliable and will consume less power. Once it has charged, you can go back to 5G. This easy routine should save on heating a significant amount, particularly in places with low coverage.
Important Settings You Should Change
You can control heating by changing some basic settings. First, set the network mode to 4G before charging. This is the most effective fix right now. Along with this, turn off Bluetooth, hotspot, and GPS while charging.
Reduce screen brightness and avoid always-on display. This slows down charging after a certain percentage and controls heat. For now, these settings are very helpful until brands release better 5G optimization updates.
Bad Charging Habits Increase Temperature
Your charging habits matter a lot. Charging the phone on the bed, sofa, or under a pillow blocks airflow. Heat gets trapped, and the temperature rises fast. Along with this, charging with a thick phone case also traps heat. Using the phone while charging, especially on 5G, makes heating worse.
Watching videos, gaming, or video calling during charging should be avoided. For now, always charge your phone on a flat, open surface. Remove the case if it is heavy. These simple habits allow heat to escape easily and keep the phone cooler.
Software Updates Play a Big Role
Most heating issues after the new 5G bands are related to software. Phone brands release updates to improve network and battery behavior. If you are facing heating issues, always check for system updates. App updates are also important because older app versions may not be optimized for new networks.
After major updates, clearing the cache can also help. For now, avoid unstable beta updates if heating is already high. Stable updates are safer for battery health. In many cases, heating reduces automatically after one or two optimization updates.
When It Is normal Heating and when it is not
It is normal that 5G has some degree of heat during charging. Slight warmth is expected. However, when the phone gets very hot, such that you cannot hold it, or when the phone automatically stops charging, then you must take caution. Allow the phone to cool and then charge it.
Do not charge batteries in hot places. In case heating is on, even on 4G and slow charging, then a service check can be required. Until now, heating decreases in most instances after doing simple repairs. It does not require panic unless the phone shuts down every now and then.
