There were plenty of questions that Is there any harm to the phone? How to extend your battery life? Can we use our phone while plugged in? Can we talk while charging my phone? How much should I charge my phone? etc.

Charging your phone overnight is a common habit among people. But, what happens if you charge your phone overnight? Does it harm your phone? So, Friends, In this post, we will tell you the reality about smartphone battery maintenance, why you shouldn’t charge it overnight, and all those favorable questions asked by the user.

Does Charging Overnight Harm the Battery Lifespan?

Overnight Phone Charging is a good or bad

Charging your phone shouldn’t cause a fire. Most industry experts recommend leaving your phone in an open, non-combustible area. This includes not charging it under loose paper or clothes or under your pillow.

If you cover your phone and let a large amount of heat from charging build up, you can also damage the battery. This doesn’t mean you should overcool.

High temperatures are likely to damage lithium-ion batteries, whether they are exposed to extreme heat or cold. Your lithium-ion batteries could degenerate in temperatures as low as 32°F (0°C) or as high as 158°F (70°C).

Problems with Overnight Phone Charging:

It’s more likely that leaving a phone plugged in to charge may shorten its lifespan. Keep in mind that there are two possible outcomes to leaving your phone on charge overnight, both of which are harmful to the battery’s health and lifespan. Either you are letting it charge slowly for hours on end or you are letting it get too hot.

Follow these tips to reduce damage from overnight charging:

  • To prevent it from overheating, charge your phone on a solid, cool surface. Don’t put it under your pillow (or anything that will trap heat).
  • Before charging, remove the cover of your phone.
  • If you get up during the night, unplug your phone.
  • Continually use the official charger and charging wire that came with your phone. Since they were created specifically for your phone, they are less likely to have flaws that could harm your battery or slow down charging.
  • Make sure the power bank you use is high-quality and won’t likely harm the battery if you use it.

Things Never To Do?
Never charge a phone in extreme temperatures. Also, do not place your phone in the freezer.

Is it necessary to recharge your phone’s battery only when it is 0%?

No. Modern lithium-ion batteries can actually be harmed by being allowed to discharge to zero percent capacity. Batteries naturally lose capacity over time because that’s how they function.

Older nickel-cadmium (NiCad) batteries are the source of this myth. If you didn’t fully discharge them, these would build a “memory,” which essentially reduced their capacity.

Lithium-ion batteries should be maintained at 30 to 80 percent (you must charge your phone when the battery percentage reaches 30). The ideal situation is to keep an eye on your phone’s charge and strive to maintain it within these ranges. It’s not the end of the world if you’re a bit under or over.

Is it Necessary to Stop Charging Your Phone when it Reaches 80%?

Manufacturers rarely allow you to utilize their batteries to their fullest capacity. It wouldn’t be smart to get rid of most of the lithium ions in a layer. When your display reaches the maximum amount it is supposed to, it will still read 100%.

Samsung and other Android phone manufacturers say the exact same thing. “Don’t leave your phone plugged in overnight or for extended periods of time.” According to Huawei, “You may efficiently extend the battery life by keeping your battery level as close to the middle (30 percent to 80 percent) as possible.”

Can I Use Apps on my Phone While it’s Charging?

While your device is charging, you shouldn’t do anything that requires a lot of energy. In fact, a lot of people do. However, doing so frequently can result in permanent damage.

This is like turning up the speed of your PC’s CPU. Think about what will happen if you have too many apps running at once: it will get hot and stop working right. The “trickle charge” will also go up because of this.

Even though it might be tempting to watch YouTube videos or play your favorite game to the next level while it’s plugged in, it’s not worth hurting your battery.

This depends on how long you plan to use your smartphone, of course. Some users only keep their devices for as long as their contracts allow, which is usually every two or three years. If you often use apps while your phone is charging, it will slow down in its second year.

Don’t use apps on your phone while it’s charging if you want it to last a long time.

Still, it should be fine to check your messages or emails. Just don’t do anything that will make you tired.
