Can I Keep my iPhone Plugged in 24/7? Potential Damages? Dangers? I TETHER 20 HOURS A DAY.

Lithium Ion batteries are subject to stress if kept at 100% charge all the time. It is best to let them cycle a couple of times a week, but don't take them below 40% charge as that is when chemical changes start to occur, which shortens the life.

Out of this whole post, this is what I'm most curious about. Because think about how much more we can do with only needing 4 hours of sleep!

Haha I feel like death going on less than 8. I can't imagine 4!

Not likely that much of anything noticeable would really show up even when using the battery below 40% (short of draining it completely or close to it on a continuous/frequent basis).

How is that a comparison. We are talking about a battery. A clock and iMac don't have batteries.
[doublepost=1495078466][/doublepost]OP. Technically leaving a your battery plugged in 24/7 will decrease he health of the battery. Batteries like to be used, otherwise they lose health. How much. No one really knows. But it's not recommended to keep plugged in 24/7. At least let it drop down to 50-60% every couple days to let it be used.

They lose health regardless, even when sitting in a drawer. But yes, using them even only a little here and there might be better.

There's lots of wrong information on this thread and a couple good tips. Anyone interested in the best way to treat li-ion batteries should visit battery university.

Of course keeping the battery at 100% for long periods of time will negatively affect battery health.

Apple even introduced power management features for iPad in iOS 11.3 in order to avoid sitting at 100%.

We used to keep work phones at the office plugged in always so they'd be fully charged and ready to go but had to stop after severe battery degradation. This was being mostly always plugged in tho so YMMV.

That's consistent with everything we know about li-ion ion batteries.

Tesla tells customers not to charge to 100% for good reason. Major battery degradation occurs from:

• time spent at extreme states of charge; and
• temperature.

But in the end so what. A new battery is only $100 after this discount period ends. It's not like we're talking about a $25,000 electric car battery or a $1200 electric bike battery.

I have my iPhone plugged in for about 6 or more hours with the screen on every night (nightstand clock/alarm). I've never had an issue with the battery or with the batteries of the three devices before it that used to do this role. I tend not to plug it back in until bed time however.

So I don't see any issue.

Perhaps others might.

Just as an FYI, you wouldn't want to do this on an OLED screen, as you'll get image retention and potential burn-in.

What do you think of the idea that modern OLED screens use pixel-shifting to combat that?
