Whether it’s your cellphone, your tablet, or your laptop, you probably want it to last as long as possible. So how do we do that?
Of course, not dropping it and keeping it dry is important. But for the battery the most important thing to do is keep the phone at room temperature or cooler. The hotter the battery, the more quickly it will degrade. Freezing a battery can also be bad for it, although cool weather is normally good for a battery. Therefore, keep your phone out of the sun. Your A/C can also help save your electronics. And if you don’t have A/C and it’s really hot, maybe store or even charge your electronics in a refrigerator (although you do have to deal with condensation when you take them out of the fridge, which isn’t good for your electronics).
The other thing that is hard on the batteries in electronics is being at or near 0% or 100% state of charge. A lot of electronics now come with ways of limiting the charging so that they charge only to 80%, or that they charge to 100% only right before you wake up. Either way, the more you keep your batteries charged to less than 100%, the better. So learn how your device manages its battery charging and use that to your advantage to keep it from charging and staying at 100% for extended periods of time.
But also, don’t let your electronics get down to 0%. You could make 20% your cut off point at which you turn off your phone or tablet. That way you’ll also have some battery left in case of an emergency.
And don’t think fast charging is necessarily bad for your device. It does heat the battery up more, but it can also be handy for not charging your device up to 100%. For an example, when you get home, you can put it on a charger and then take it off when your device is at around 50% to 70%. Then, the next morning, finish charging it up to 80% by keeping tabs on it and manually disconnecting it when it’s full. This is much better than using a slow charger that will inevitably force you to leave it plugged in all night, which could mean it’ll be sitting at 100% for several hours.
Anywho, I hope that helps.
