Stop Charging Your Phone at Night, Here's Why

  • Published: 06 November 2019
  • 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.

    - 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%.

      I know that some batteries when used a long time their voltage increase and the amperage drop design a actual intelligence transformer too reduce voltage and convert it into amperage thus making the parameters nominal

        by the time the battery is stuffed it'll be time for a new phone anyway.. I usually update every couple of years, so battery life is not really that important.

                Yeah that's why phones have battery optimization & learns your charging patterns also your sleeping so that it doesn't charge no higher than around 80 percent abs starts back charging when you're about to wake up

                      What heats up your phone is leaving it on 24/7. Turn it off and charge it over night. I've had the same phone for almost 7 years that I paid 100 bones for. I know people that go through $500 I phones every 1-2 years. I'll stick to what I've been doing. This has to be one of the dumbest misinformed videos ever made.

                                    Blatant lies. Phones get 5v from the wall through your power brick, no high voltage. Phones will shut off charging to the battery after it gets fully charged and will use power from the wall as to not discharge the lithium cell

                                                      this is BS most phones have protection against battery getting overcharged once it reaches 4.2v it shuts power to it and most phones use power from the power brick meanwhile it's still plugged in

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.

                                                                                          • ML ThugLife

So charge your phone all night it doesn't make your battery life bad as much as you are from using your phone all the time.
