Charging cellphone

Have you ever thought about "Is it safe or not to charge your cellphone battery all night?" That question may often arise when you are about to charge your cellphone while going to sleep but you still haven't found the answer. This article is perfect for you, please read to the end!

In my opinion, questions like this are very common. The reason is, there are many myths that say that battery can quickly leak or get damaged quickly because it often charges overnight.

So, is myth that charging a cellphone battery overnight can make it damaged quickly is true?

Myth that charging cellphones overnight can make battery leak has actually been around for a long time. In early days of cellphone's presence, this often happened. Battery may swell because it has been charging for too long.

However, that was in past. Now, cellphone is getting smarter and more sophisticated. Smart phones are now equipped with a chip called Power Management Integrated Circuit (PMIC). From name, maybe you can already guess its function? PMIC serves to regulate flow of electricity that enters device. Chip also functions to monitoring cellphone charging process. Interestingly, when cellphone battery is full, PMIC can cut off incoming electric current.

This means that you can charge your cellphone overnight. Guaranteed, battery will not overcharge and become damaged. When battery is full, device will automatically cut off incoming flow, even though cellphone is still connected to charger.

Want to know proof? Try charging it for 10 to 15 minutes. During this time, try to hold back of cellphone. Warm and tends to be hot, right? Hot battery is natural because battery is charging.

Well, try to compare it in morning after you charge battery overnight, cellphone's body doesn't feel hot, right? That's a sign device is not charging battery.

My answer is you can just sleep when your cellphone is in a state of charging. Guaranteed not to overcharge until it swells.

Even so, there are some things you should pay attention to. As mentioned in previous point, cellphone charging can make body hot. Therefore, it should not be placed in a place that is not heat-resistant.

In addition, cellphone batteries also have cycles. If it has reached maximum charge cycle limit, battery performance will indeed decrease. If your battery's performance has decreased, it's likely because battery charge cycle has reached its maximum point, not because it was charged overnight.

Then, there is another myth that states you have to wait for HP to 1% to 2% before refilling. So, is the myth also true?

If we look at cellphone at the beginning of its appearance, that myth is true. Not because it can damage cellphone batteries quickly when charging from 20%, but performance of old cellphone batteries can indeed be better when charged from an empty state. At that time, cellphone used nickel-cadmium type batteries.

Li-ion battery

Well, the new cellphone already uses a lithium-ion battery. This type of battery can be charged, without having to think about remaining battery. So, you can charge battery at any time even if capacity is only 50% or 90%.

Bonus info: You can also use your cellphone to make calls while it's charging.

Many say that don't charge your cellphone while calling. Well, that's a false myth. In fact, you can still charge your cellphone, even when you're on calling. It's just that, charging it will take longer. This is because electricity used will come from charger. So, electricity from charger does not flow to battery, but to provide power to phone.

Well, that was the explanation about charging your cellphone overnight and some other information. Hopefully it's useful and you don't hesitate when you charge your cellphone overnight.

My phone will stop charging right after it reached 100% if I charged it overnight. How about you do some vc overnight while charging, will it create problems?

Do not leave your phone connected to the charger for long periods of time or overnight." Huawei says, "Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life." The official word is to keep your phone charged – but not fully charged.

I don't think there's problem in charging out phones overnight. Once our device is full the power would be disconnected automatically. So the technology of nowadays is really smarter than before.

However, in iPhone battery health is important. Feel so sad that it is 99 percent now even if I just bought it last March. I had left it charging overnight for some time.

I think for the latest cellphones, all of them already have advanced charging and battery protection features.
