There is no danger in using your phone while it's charging. When you use your phone while charging, the battery is charging at a slower rate than normal to allow enough power for the ongoing usage.
Why does my phone get hot Usually, a phone heats up due to overuse, a strained battery, too much direct heat, or an overworked CPU. You may also need to update your software, because outdated apps can cause performance issues. In extreme cases, your hot phone might be infected with malware.
Charging overnight is not a danger to your battery in and of itself. However, temperature is a real concern. One of the most damaging things your battery can experience is extreme heat or extreme cold. Apple has publicly stated that temperatures above 35 degrees Celsius can cause permanent damage to battery life.
So at what percentage should you charge your phone The best practice for preserving phone battery health is to plug it in at around 20% and charge it up to 80-90%. This is especially important if you use fast charging, as charging from 0% will cause a lot of heat, and from 80% up, fast charging becomes less efficient.
Phones usually get hot because of an overworked battery. A little heat coming from the back of your phone is normal because modern phone batteries emit heat while in use. But prolonged or extreme heat can signal something more serious, like outdated software or apps that cybercriminals can exploit.
5 tips to stop your phone from overheatingAvoid direct sunlight on your phone.Lower your screen brightness.Use a manufacturer-approved charger.Turn off unused apps on your phone.Keep your apps up to date.Fan your phone, or blow on it.Avoid sudden changes in temperature.Take it off—the case, that is.
The most common myth about overnight charging is that it can overload your battery. This is simply not true. All smartphones are designed with protective measures that prevent the battery from overcharging once it's full. As soon as the battery reaches 100%, it stops charging.
If you leave a device plugged in even after it is charged 100% It can over-heat.
Here are 10 things you can do:Keep your battery from going to 0% or 100%Avoid charging your battery beyond 100%Charge slowly if you can.Turn off WiFi and Bluetooth if you're not using them.Manage your location services.Let your assistant go.Don't close your apps, manage them instead.Keep that brightness down.
Apple recommends, as do many others, that you try to keep an iPhone battery between 30 and 80 percent charged.
Your cell phone works best at temperatures between 0 and 35 degrees Celsius (32 and 95 degrees Fahrenheit). Exposure to extreme temperatures outside of that range can impact your phone's performance and hardware.
Put Your Phone Into a Cool Place
Never put it into the freezer or refrigerator, though. Cold temperatures can damage your phone, too.
If your phone is getting too hot, sometimes it needs help to get back to a normal temperature. The good news is, that the majority of the time, even if your phone overheats and displays a warning, once it cools off there's no permanent damage.
There are too many apps running in the background. The screen is too bright. The screen is staying on too long before going to sleep. The phone doesn't have service.
Put simply, you can safely charge your devices overnight without having to worry about damaging their internals. Modern electronics automatically stop pulling current once their batteries reach 100% charge. However, charging your smartphone to full each time isn't ideal for battery longevity.
For optimized battery life, your phone should never go below 20 percent or never above 80 percent. It may put your mind at ease when your smartphone's battery reads 100 percent charge, but it's actually not ideal for the battery. “A lithium-ion battery doesn't like to be fully charged,” Buchmann says.
Apple considers any iPhone with a battery capacity of 80% or above to be in optimal condition. In fact, Apple feels so strongly about battery health that its 1-year warranty covers any battery at 80% capacity or more. It's not unusual to see iPhones that, after one year, still have a battery capacity of 95% or above.
It's especially important to avoid exposing your device to ambient temperatures higher than 35° C (95° F), which can permanently damage battery capacity. That is, your battery won't power your device as long on a given charge. Charging the device in high ambient temperatures can damage it further.
Store it half-charged when you store it long term.
Therefore, we recommend the following: Do not fully charge or fully discharge your device's battery — charge it to around 50 percent.
And to do that on your Android, go to Settings, then Gear, then Data Usage, and finally, Restrict Background Data. During the summer and winter, extreme temperatures can drain your battery life. The hotter (or colder) your phone gets, the faster your battery will head down the drain.
Getting your phone out of these hot environments can cool it down immediately — try putting it into a dark room or even cool it down with a fan. Never put it into the freezer or refrigerator, though. Cold temperatures can damage your phone, too.
Low temperatures can rapidly drain your phone's battery life, and — as you've probably experienced — cause your phone to shut down altogether. Thankfully, you can take tried and true measures to prevent this from happening. Here's what you need to know to keep your phone alive when the temperature drops.
The most common way that a smartphone will overheat, however, is when people charge their phone for too long. It might sound simple — and it might not get the phone to temperatures that will cause it to explode — but it still happens to many phones on a regular basis.
It was thus found that the dark mode can significantly save battery life in peak brightness, usually employed by smartphone users in outdoor conditions under sunlight.
Lower background activity
Apps like Facebook® and Instagram can still run in the background, checking for updates, refreshing content, and pushing notifications, even after you've closed them—which can drain your phone battery.
