Should you leave your smartphone charger plugged in all the time?

“Do not leave your phone connected to the charger for long periods of time or overnight.” Huawei says, “Keeping your battery level as close to the middle (30\% to 70\%) as possible can effectively prolong the battery life.” The official word is to keep your phone charged – but not fully charged.

Does keeping your phone plugged in ruin the battery?

Charging My iPhone Overnight Will Overload the Battery: FALSE. Once the internal lithium-ion battery hits 100\% of its capacity, charging stops. If you leave the smartphone plugged in overnight, it is going to use a bit of energy constantly trickling new juice to the battery every time it falls to 99\%.

What happens if you charge your phone with a more powerful charger?

If you use a charger with more current capability (and that’s the key – it’s only capability – it doesn’t force that much current through your phone), the phone will charge at its full rated current, so it charges faster.

How many amps should I charge my phone with?

However, a typical USB port will charge at between 0.5 to 1.5 amps. If your phone can handle anything above 1.5 amps, then a USB port will charge it more slowly than the charger that came with your device. Even without branded “quick chargers”, some chargers can fill your battery faster than others.

Should I turn my phone off at night?

Powering down your smartphone at night won’t help preserve the battery, since it’s unlikely that you’d be using the device at that time, anyhow. “It comes to how hard you use your phone,” says Weins. Periodically draining your battery to zero percent and letting your smartphone die is advised, though sparingly.

How much does it really cost to leave your phone charger plugged in?

This Isn’t Meant to Be Precise, But It Answers the Question. This isn’t meant to be a completely scientific or precise test, of course. Some of the chargers likely use more power than others, so the real cost to leave your smartphone charger plugged in for an entire year is probably below 13 cents.

Does a smartphone Charger consume power when it’s not charging a smartphone?

I then took a genuine Apple iPhone (a 5W charger that comes with with the iPhone 11) charger and let it sip power with nothing attached to it over the course of a few days. No surprise here: a smartphone charger consumes power even when it’s not charging a smartphone. But how much power does it consume?

Are non-genuine Chargers worth it?

Non-genuine chargers can draw a lot more power (up to 10 to 20 times more, based on my testing). On top of that, the cheapest and nastiest chargers aren’t the sort of things I’d be comfortable leaving plugged in all-day, every day.

How much power does an iPhone charger use?

According to my tests, a genuine Apple iPhone charger uses in the region of 135W of power a month, which equates to just over 1.5KW h a year, which means that if I lived in Hawaii, that charger would cost me $0.46 a year it I left it plugged in doing nothing. If I decided this was too much and moved to Louisiana, I’d save a quarter.
