The battery is the primary source of heat in a smartphone.
If your smartphone is overheating, it’s probably the battery’s fault. “But my smartphone sits on a table or in my lap. What does its battery have to do with that?” you might ask. Well, did you know that charging your smartphone is the most common cause of overheating? This should come as no surprise since heat is generated as the battery charges and discharges. Unfortunately, when a battery overheats it not only causes discomfort to users but also may damage the device itself via shortened life cycles.
We’re here to help. Let’s take a look at some solutions for an overheated smartphone!
Smartphones heat up when being charged.
When you charge your smartphone, and you play games or watch videos on it simultaneously, your smartphone gets heated up. This is because the battery and the processor are in use at the same time when playing games and watching videos. Therefore, it’s advisable to avoid such activities while charging your phone to reduce its temperature.
Modern smartphones are designed to regulate their temperature by switching off when they become dangerously hot (for example, when left in direct sunlight). However, constantly using a device that becomes uncomfortably warm is undesirable as this will continue to damage the battery over time.
Keep your smartphone away from direct sunlight.
- Keep your smartphone away from direct sunlight.
- Of course, it’s not always easy or practical to keep a phone completely out of the sun — especially if you’re using it outdoors during the summer. When you can, use an umbrella or other shade to keep your phone cool. If you’re in a car, look for a windshield shade that will help reduce heat buildup in the front seat. If your home gets direct sunlight through windows and you tend to charge your phone at night near one of those windows, consider moving the charging station away from the window to help reduce heat buildup while charging.
- Apply common sense: Consider where and how much sunlight is getting on your device when it isn’t being used; make adjustments accordingly. For example, if you store your smartphone in a hot car most days and then wonder why it gets warm when you turn it on again later in the day, consider keeping it somewhere else — like inside a backpack or purse — instead.
No matter how you use your phone, take frequent breaks.
No matter how you use your phone, take frequent breaks. You may be tempted to constantly use it, but that’s a recipe for disaster in more ways than one. If you do use your phone for extended periods of time, don’t go from one activity to another without taking some time off in between. For example, if you’re streaming a video on YouTube, try doing some brief exercise—such as jumping jacks or a few yoga poses—afterward. Or go outside and get some fresh air and sunlight!
Also, consider stretching your legs every once in a while; walk around the room and/or get a drink of water. Getting up from wherever you’re sitting can also be good for your eyes, especially if you’re reading something onscreen. While standing or walking around, try breathing exercises to clear any tension out of your body—and get more sleep while you’re at it! Putting the phone down when it’s bedtime will help ensure that you get the rest necessary to fight off stress and fatigue the next day.
If you can’t avoid charging your phone, keep the battery level between 30 and 80 percent.
Charging your phone puts strain on the battery, so it’s important to keep this to a minimum whenever possible. But if you do need to charge your phone, avoid letting the battery get too low and then plug it in. Instead, keeping your battery between 30 and 80 percent is generally regarded as the safest range of charge levels for most smartphone batteries.
Remember that the more you use a charger (be it a wireless charging pad or a Lightning-to-USB cable), the more wear and tear is put on both the USB port and battery of your smartphone. This can result in reduced battery life over time as well as heat buildup when charging your phone, which can lead to overheating issues. It might seem like common sense, but one way to prevent overheating from happening during charging sessions is by leaving plenty of space around your device when charging.
Turn off unwanted features such as GPS and Bluetooth when not in use.
When not in use, unwanted features such as GPS and Bluetooth can be turned off to save battery power.
- Unwanted features such as GPS and Bluetooth are high energy consumers.
- Turning off GPS and Bluetooth when not in use will save battery power.
- Turn off power-hungry features such as GPS and Bluetooth when not in use.
Your Android smartphone may overheat for several reasons, but there are ways to keep it cool.
It’s normal for your smartphone to heat up a few degrees during many of your day-to-day activities. For example, when you’re charging your phone, the battery creates heat as it charges, which is why you should always keep it on a flat surface rather than in your hand or pocket. Also, when exposed to direct sunlight for an extended period of time, your device can get hot enough that the screen dims automatically.
Your device will also get warm any time you use it intensively. This includes using the camera, GPS or Bluetooth while playing a game or streaming video online. You may also see an increase in temperature if there are too many apps running in the background.
