Stop Charging Your Phone at Night, Here's Why

It’s a basic thing – you want your phone fully charged in the morning so it’ll last through the entire day. And even with cutting-edge smartphones that can charge to max capacity in a matter of an hour, there’s no guarantee that you’ll remember to charge it in the morning while you’re in a sleepy daze.

Advice to leave your phone unplugged during the night may seem risky. The worst fear here is that your phone will charge down while you sleep and won’t see the dawn of a new day to wake you up like you’re used to. But still, you can’t go against the word of science. Leaving your smartphone on a charger is bad for it.

SUMMARY:
- Even though lithium-based batteries are rechargeable by nature, and made with this process in mind, they’re highly vulnerable to constant interactions with high voltage electricity, like in the outlets of your house.
- There are automatic switches on your phone that’ll stop the charging process the very moment it reaches 100%. But when your phone naturally goes down to 99%, the charging will start all over again.
- Good, high-quality chargers have special chips in them that prevent overcharging. So it’s advisable not to skimp on chargers – this way you won’t spend much more money on a new battery or entire smartphone too soon.
- Overall, it’s always advisable to use good quality tech when it comes to something as expensive as smartphones these days.
- Heat is bad for batteries. That’s why it’s so harmful to your phone if you leave it in a closed car in the middle of summer.
- You’ve probably heard something about fully depleting the charge of your smartphone and then charging it to the maximum capacity. This is fair for devices from the past decade.
- Any modern lithium-ion battery won’t get lazy like a cadmium based one, so you don’t have to worry about that.
- Scientists and engineers promise that soon, we’ll have another kind of lithium-based battery that’ll be able to charge in a matter of minutes and last for more than one day.
- One of their new ideas is to make battery chargers that can produce energy from a Wi-Fi signal.
- And how about charging a phone with a sound? Using piezoelectric principals, tiny nanogenerators will be able to transform the surrounding sound to electric power. -
- Scientists from Japan are in the middle of a decades-long study that will allow replacing lithium ion batteries with sodium.
- Another idea is to use literal sand in batteries. Not quite literal though, as this battery will use silicon – the main component of the sand.
- But for now, the best course of action is to use good quality charging equipment, keep your smartphone out of the heat, and most importantly, keep the charge in it between 30% and 90%.

Hey guys! How often do you charge your phone? ☎️

[IshanAli]

This many people charge their phone at night
👇🏽

[epicgalaxist]

Me: *watches this video*


Me about to go to bed: Time to charge my phone

[rayyan]

"You'll be lucky if you your phone lasts longer than an year" me laughing with a 7 year old tablet lol.

Me watching this while charging my phone at night😂


Edit: thanks for 30 likes! Never reached this amount of likes till now tysm!

I have charged my phone overnight for 3 years and is still good.

[lucie]

Been charging my phone every night for almost three years and my phone is fine

The charger (a circuit inside the phone) stops charging when the battery hits 100% (not "100%" indication on the screen, 100% of the "not being charged" voltage at the terminals). When the battery drops to somewhere between 97% and 99% (depending on what the manufacturer has chosen), the charger starts charging again.

The thing you plug into the wall isn't really a charger, it's just a source of power. A well-designed one doesn't let the phone see "raw power", the phone sees 5 Volts (or 9 Volts or 12 Volts, depending on what the charger is calling for). Don't charge your phone all night WITH A CHEAP DOLLAR STORE CHARGER. But the manufacturer's charger is normally safe. (And the phone's battery will be fully, or almost fully, charged in the morning.)

"Don't let your phone charge all night" is just another urban legend that's been shown, over and over, to be false.

This is officially obsolete w/modern mobile devices. According to Apple, charge your iPhone whenever you want. Trickle charging won’t effect your total cycles. Also, Qi technology protects from overheating and overcharging. Don’t listen to this guy ^ except for not leaving your battery in a hot locked car or similar place.

As an electronics engineer and lithium-ion battery expert I can say you can safely ignore all advice in this clip. Modern cell phones have extremely good battery management. The only thing I do differently is to use the slowest / least powerful charger I can find so that my battery charges slowly at night, thus reducing cycling wear. This is typically the 500mA available from the slower/older usb chargers and sockets. I also avoid excessive heat for prolonged periods to reduce calendar aging. My Samsung S4 is around 6 years and the original battery is still in good shape.

Had my phone for 5years now and wasn't aware of this problem, I have charged it overnight since I bought it and it's still going strong so it's to late to change now so I'll carry on.

This should be titled " Stop Chadging Your Phome While You Sleep, not just at night. I worked graveyard for many years & that means sleeping during the day.

1:13 "They're highly vulnerable to constant interaction with high voltage electricity, like in the outlets of your house." The phone gets 5vDC at 1 - 2A, (not 120v @ 60Hz) which is exactly what it's designed for. As for the explanation of a NiCd battery's memory effect... You CAN fully charge them but they will only discharge partially to the 'memory' point, limiting it's useful capacity.

"You'll be lucky if your phone lasts a little over a year"

*Laughs in 5 year old phone*

[claudiacadogan]

I love how this pops up when after I just charged my phone over night and still charging it

[Me_RajRocks]

Thank you for this fun fact lol 😂
I am charging my phone over night every day and its been 5+ years now 😁 no battery issue

[nakayle]

Seems to me, since smartphones have a clock, it would be easy for them to turn off the charging for six hours when it reaches full charge to prevent the cycling you mentioned.

[jungkookie]

Me: *watches the video*

Also me: meh *charges my phone at night*

[someonewashere]

“You’d be lucky if your phone lasts a little over a year”

I’m sorry but mine lasted for over 4 years

[malakshamseddine]

Oh I charge every every every night 😂 and after watching this video guess what


I will still charge it every night :)
