Keeping Lithium-ion batteries at 100% charge will reduce their lifespan. They want to live in the 40-80% range. I use an app that notifies me when my phone has charged to 80%, so that I can unplug it. It may be overkill, but I plan to use this phone for 9 more years or so.

Both iphone and androids have an OS option to stop charging at 85 though - I keep it on all the time unless I'm going to need that extra bit of juice
9 more years?? I've gotten almost 6 years out of my Oneplus 5T and I've been ecstatic about it. It's literally lasted 3 times longer than any phone I've had before it
Me too. Samsung has a feature to "protect battery life", so it only charges until 85%. You can keep it on power, but it won't surpass 85%.
they forgor
Don't you like... live with your wife...? sleep in the same room...? You should be the one with the answer. π
Lol I was going to say something similar. Justβ¦ask her?
Fire hazard.
I charge it at work while I'm (mostly) conscious. xD

This. I'm surprised Fire Hazard is not the top answer in this thread...
I used to never charge my phone at night, because of my battery health pedantry. I the found the AccA app which enables me to limit the maximum charging, so now I sometimes leave it changing during the night.
If you're still convinced you need to run your battery down to zero you're operating on outdated knowledge of NiCad batteries and ruining your lithium ion batteries.
My Android phone has a built in functionality to charge so that it hits 100% when your alarm is rigged to go off. Idk about iphone though.
I was not talking about running the battery down to 0, that's no good for li-ion batteries either. I was talking about the exact, opposite, reaching 100% and staying there for hours on end (which happens during the night). With AccA I can set an upper limit.
Hi Tmpod! This is actually a common misconception among the general device-using public!
You are absolutely correct that a NMC-chemistry lithium battery (this is the kind of battery used in phones) will degrade if you maintain a state of charge (βSOCβ) for long periods of time that is either above 90% or below 10%. Of course, phone manufacturers know this too, and they have set the charging software to block off the top of the pack, which allows the user to safely leave their phone on the charger indefinitely.
Why can't it be as easy as a relay (or transistor) switch that cuts off the power?
This is basically how charging works today. There are transistors in the power management module that stop the battery from charging once it reaches the specific voltage that the software deems is appropriate

Requires root? I'd rather degrade my battery than run an out-of-date, more vulnerable operating system..
I use a chargie. It's a physical Bluetooth connected device that connects between the phone and charger and lets you set your own charge limit. Works great with my wireless charger at night. I also have one for my tablet.
I just fall asleep while watching a yt video of something and the phone is still in my hand.

I charge my phone at work ...
I feel this pain. Wife's battery-powered devices are always in a constant state of dying. Something has convinced her that it's better to let the battery almost! die, then charge it to full, but not leave it plugged in because that will degrade the battery; meaning it never gets charged overnight. I'm sure there's a small kernel of truth in where she learned that, but it's almost a joke at this point when she goes scrambling for her charger when using her phone, tablet, etc. It's painful, but also adorable? I guess. Anyway, it's not a hill I'm willing to die on, so I just let it be and laugh almost everytime it happens.
I think that was true like.. 10+ years ago, but battery and power management tech have advanced so that's no longer necessesary. I think running full cycles on your battery is actually bad for it now, I set mine to stop charging when it hits 85% to preserve battery health.
Sounds stressful constantly worrying about battery life, plopping it on a wireless charger before bed is the way to go.
She needn't worry about manually optimizing battery wear, and, in fact, the most harmful thing you can do to a battery is to fully deplete it frequently.
Educate her about built-in optimized battery charging. iPhones and some Androids have it.
This. My wife and I have that setting turned on on our Samsung phones. Mine is 3 years old and I still get all-day battery
Something has convinced her that itβs better to let the battery almost! die, then charge it to full, but not leave it plugged in because that will degrade the battery
That was true a long time ago when NiCad batteries were around. But, since they had the problems you described, they're not around any more, and phones generally all use lithium-ion batteries which don't have this issue.
Same thing with my girlfriend. I even got a charger and a cable just for her exclusive use but she keeps unplugging my phone because "it has more charge than mine". Which, fair, but like??? It didn't have to be this way??
when i see people's phones constantly at, like, 12%, it drives me crazy.
Haha it's always funny with screenshots posted on social media, like 4% I'm sweating π
It doesn't matter when you got a fast-charge phone.
One of my phone's puffed up while being on the charger at night. Woke up next to a spicy pillow.
I work from home on a desk job. I charge my phone once a day so now I do it at 4pm everyday and follow that cycle.
I don't want an exploding phone in my bedroom. I charge it at my desk while working
Eh. I only use the thing once or twice a month. Itβs dead most of the time, really. Unless I plan to use it I usually donβt charge it at all.
There's actually a safety factor there. When Li-Ion (lithium-ion) batteries fail and suffer thermal runaway (fire), it's most commonly during charging. It's rare, but it does still happen. The rule is to avoid charging Li-Ion powered devices unattended. I do that at times myself, but I realize the risk and actually put things in a "charging pot" if unattended.
You don't need anything fancy to use as a charging pot, a ceramic casserole dish will do. If you're going to charge while asleep or out of the house it's not a bad idea to use some kind of containment.
Bringing back chamber pots one person at a time
Because I try to charge my phone when I am in the office, as much as possible. There are no small savings in my book :D

Some people just don't give a f*ck, even when they complain about it all the time...
I charge it during the day at work.
Boss makes a dollar I make a dime...
... that's why I charge on company time
I have a wireless charging stand at work, so my phone is nearly 70% charged when I go to bed. No real point to me in having extra clutter on my nightstand.
On the weekends, Iβll charge my phone on the kitchen counter while making breakfast for the kids.
Sometimes I fall sleep while scrolling or watching something in bed, so no overnight charge
No good for your health my guy
I thought you're not supposed to keep things charging after they reach full battery. Also I don't have a plug near my bed lol
Recent smartphones learn your patterns and don't fill up until the morning. For instance my phone currently is stuck at 80% and says it'll be fully charged at 7AM
