5 Common Mistakes When Charging Your Cell Phone

common mistakes charging phone

We still worry about that charger we left in the power socket, the iron we forgot to unplug, the laptop we left on all night, and to discharge the phone to 0% so that the battery won’t break. Do we need to continue to worry about these things? Or can we be “bad guys” and leave our phones charging?

We’ve decided to learn more about these common questions. Because while the devices we’re using every day are new, our knowledge about them may be old.

Myth № 1: You shouldn’t charge your phone overnight.

Thanks to modern lithium-ion batteries, you can easily charge your phone overnight. These kinds of batteries have controllers that stop charging when the battery is full. So don’t be scared of starting a fire or that your battery will break upon charging.

The only thing you may want to worry about is overheating the phone. Because the heat-exchange is not perfect, it may not be the best idea to charge your phone overnight. In order to avoid buying such a model, read its reviews carefully.

Myth № 2: You should discharge devices to 0%.

Let’s talk more about lithium-ion batteries. The thing is, they have a limited number of charge cycles (for example, an iPhone has around 500 cycles). One cycle is the full charge from 0% to 100%. If you charge the battery from 90% to 100%, you use only 1/10 of the cycle.

In order not to waste one full cycle, you’d better charge your phone several times a day (if you have the chance, of course).

According to experts, your battery will work for a longer time if you keep the charge somewhere around 40% to 80%.

In the past, experts recommended discharging the battery to 0% but today more and more batteries have a built-in calibrating device. These smart batteries reduce the necessity of calibration, however, if your phone is acting weird like if it’s losing its charge very quickly, you should calibrate it manually from time to time.

Myth № 3: You shouldn’t leave the charger plugged in.

Despite the fact that it’s convenient and you won’t need to look for it all the time, safety rules say that chargers need to be unplugged right after using. This is because a fire could start as a result of a power surge.

Such situations, especially in cities, happen very rarely. So this precautionary measure is mostly useless. However, there are 4 times when a charger should be unplugged:

  • Your house doesn’t have lightning protection, so there are frequent power surges and electricity is often off.
  • You have animals that are free in the house. In this case, they can easily bite the power cord, and it’s better if it’s unplugged.
  • Your neighbors have water leaks.
  • Your charger heats up or makes noises even when it’s not connected to the device. In this case, it’s easier to replace the charger instead of the entire apartment.

So, it’s up to you to decide whether you will leave the charger plugged in or not. It won’t break down, so this is not something you should worry about.

Myth № 4: Laptops may not work if they are constantly charged up.

The same thing goes for your laptop as with your phone: modern batteries block the charging of the battery when it’s full. Just in case, experts recommend discharging the battery to 0% just once a month.

Overheating of the device or working in bad conditions are more often the cause of any damage. So mostly, it’s the mistakes of users, not the charger that can ruin the device.

Myth № 5: Turning your phone off will damage the battery.

Experts suggest that turning your phone off can help preserve your battery for longer. But don’t bother turning off your phone if it will only be off for a short period of time. The battery-boosting benefits of powering off only take effect if you power off for a few hours or more. If you have your phone plugged into a wall outlet when it is off, you also won’t get any of the benefits.

However, if you’re out of network range or if you are planning on going to sleep without charging your phone, go ahead and turn off the phone. When off, your phone won’t lose power. This will really help to extend your battery’s life. Remember, the average Android only has 300 to 500 full charges before it starts to malfunction — or die altogether — so if you can eliminate needing to re-charge by powering your phone off, why not do it?

What Are Some of the Side Benefits of Powering Off?

Turning off your phone doesn’t just benefit the battery. You’ll also gain focus for work. For example, experts say that the human mind isn’t adept at multitasking — that belief was a pesky myth. You may think that your mind likes the stimulation of switching between many activities — like constantly checking that phone — but really, that click-around behavior isn’t helping you be efficient. To be more productive, power off for a while.


The conclusion: Modern technology is so advanced that we don’t have to worry about a device left charging overnight. And if you do decide to be paranoid, you should go all the way and unplug all devices starting with your phone and ending with your fridge.
