But the question is: Should you be leaving your phone plugged overnight? Is it safe?
The Rumors About Leaving Your Phone Plugged in:
It isn’t only the safety of your phone one should be after when leaving it plugged overnight, but the safety of your wellbeing as well. You’ve probably heard horror stories about phones exploding and ruining beds or houses because of the accidents, and it’s no joke to laugh about. That’s why it’s best to know if you can leave your phone plugged overnight to avoid these kinds of accidents and any injuries that may happen. You’ve probably also heard that phones tend to decrease battery power the more you leave it charged overnight, or that it will forever be damaged if you keep continuing the habit. There are many myths and rumors you may have heard from parents and friends, and it’s time to debunk them! Will you need to worry about injury or damage to you or your phone? Let’s find out.
You won’t need to worry about any of that. We’ll get into the details in a bit, but if you’re really curious and want to know beforehand, then YES! Yes, it is possible to leave it overnight without fear of damaging your phone. But this wasn’t always the case, as this piece of advice goes for newer models of phones. Again, we discuss why and even include tips on how to charge your phone effectively.
Lithium and Nickel:
Your new smartphone’s battery most likely runs on lithium ion. But before that, your previous phone battery was made out of nickel, similar to the circular batteries you buy in any store such as Energizer. These nickel batteries haven’t been used in any phone since the early 2000s, as they are now using lithium ion. Nickel batteries are cyclic batteries. If it isn’t fully charged after a long time, then it may forget its full capacity of its battery life, only remembering the last time it was charged being the extent of its battery life.
The lithium ion batteries are different though, not suffering through these memory cycles the old nickel batteries had. Compared to nickel batteries, lithium ion batteries hold more power and what’s cool is that they are able to handle all that power in smaller and lesser weights, which is why smartphones today are smaller and weigh less. They are also able to charge quickly and are less likely to heat up.
Battery Murderer: Heat
What threatens to kill the lithium battery of your phone is HEAT! While batteries aren’t safe towards cold weather either, heat is far more dangerous, and the reason why we can answer the question if you can leave your phone charging overnight. The charging temperature of lithium batteries is 32 degrees, while it discharges at -4 degrees. It will be able to charge faster at 41 degrees. When it is fully charged, a battery will give off heat as a way to release the power as it charges, which is why you would often hear people talk about their phones overheating while plugged overnight.
Luckily, your smartphone uses their battery smartly, meaning there’s no cause of worry if you leave it charging overnight. Your smartphones will stop charging once they detect that it is fully charged, using the charging port as their battery source instead of their own lithium battery.
How to Charge Your Smartphone’s Battery:
BUT, that doesn’t mean that you’ll be able to keep doing this. Your phone may end up losing a bit of its battery strength and life in the long run. So here are some quick tips on how to charge your battery effectively without losing power:
- Your smartphone’s battery has a limited number of battery cycles. So that you can maximize its number of cycles, make sure that you keep your battery between 40 to 80 percent. It may not be always possible, but try not to drain your phone’s power every time you use it. It’s best to keep it between those percentages to avoid losing its battery life.
- Don’t use fast charge every time, only during emergencies or if you are truly in a hurry. Like mentioned, fast charging causes your battery to heat up more so than usual, which can also be bad for your battery. If you keep doing this, your phone’s battery will end up having a shorter lifespan because of the excess heat it produces.
- It’s best to do a whole discharge cycle every once in a while, usually monthly. Drain your battery until it’s shut down, and charge it until it’s fully charged. Don’t open up your phone until it signals that your battery is now full. Once it is, turn it on and begin using it again. That way, you get to save your battery’s power and optimize it.
The battery is the most important part of a phone. After all, how will you be able to use your smartphone properly without a working battery? You will need to make sure that your battery is working perfectly in order for your phone to be utilized, and to make sure you take care of it as much as possible, avoiding it from being damaged. To answer your question if you are able to leave your phone overnight? Yes, you can. There is no problem with that. As long as your phone is ready for you to use for the day ahead, then you can charge it all you want without worry.
