I've seen many people state that, and yet I've never cared and never had a problem. The oldest phone in my family is my mothers and her iPhone 8 is 5 years old and has 86% battery health. She charges it overnight every night and sometimes in the day too,

I rarely keep phones longer than 2 years so it's never been an issue for me, but my wife's iPhone 12 bought at release is now on 91% after just over 2 years. Hers is also charged overnight every night.

People tend to get a bit obsessed with battery health, but all batteries will degrade over time, there's nothing you can do to prevent it, and inconveniencing yourself and not getting the full experience out of it seems like more hassle than it's worth to just delay something that's inevitable for a little while.

Yeah don’t go below 20 and above 80, that’s the rule.

You can go above 80 every once in a while if you need the extra battery for like a whole day out.

It’s better to recharge randomly during the day, like if you’re going out and you have 40% left, just charge a couple of minutes as you get dressed or something, so you’ll have more battery life.

So move between 20 and 80 as much as you want.

Just charge it to 100% overnight and quit worrying about battery health. The battery will wear no matter how you use it, and will need replaced at some point as it is a consumable wear item.

Eventually your capacity will shrink, nothing you can do about it

My iPhone 13 mini I've bought in March this year is at 99% battery health and I don't think about charging at all. No matter if it's at 10% or 40% - if I'm going to sleep, the iPhone is going to be charged. If I'm driving 10 minutes home from the office - the iPhone is going to be charged, I don't care if that's right or wrong.

Stop worrying and just use your phone.

100%

Just use your phone and live. You have a $1000 device, let it do what it does. Stop worrying about dumb stuff like this, your battery is going to degrade no matter what

Battery optimization is built into the software. You don't have to do anything special.

Rather than listen to "most people", listen to Apple:

Another battery question that could have been searched for in this subreddit with less effort than making this post.

The best way to preserve battery is just keep your phone off and charge to 60% every few months. Stop fucking worrying about it, it’s cheap to replace and likely you will trade it in before it hits less than 80%

This is factually incorrect.

Lithium ion batteries do not have memory. They degrade based on cycle count and operating temperature.

Discharging from 100% to 0% imparts as much wear as two-half cycles, for example 80% to 30% twice.

Charge your device freely, it will optimize the rest.

Crazy how obsessed folks became once apple started reporting this.

What does memory have to do with it? Above 80% and under 20% the battery is more stressed, and you don’t want that.

Why the fuck do you think Samsung added a feature to cut charging the battery above 85%?

Stop worrying about battery health. Use your phone. Charge it how you want it. You're only going to have your phone for 2-4 years most likely, and the battery will last far beyond that.

Ever since Apple started showing battery health, it's become an unhealthy obsession that none of you ever cared about before it was an available feature.

Then why would Apple bother to write all that

They actually do

They mention operating temperature as a critical component as well as how their batteries are rated for 500 cycles before hitting 80% residual capacity. You can use optimized battery charging if you wish as it slightly reduces cycle count by holding the phone at 80% before finishing the charge to 100% instead of allowing for small partial discharges at 100% which count towards your cycle count.

See my reply to the other commenter above. It's about cycle count and temperature, my friend. Not a battery getting "stressed" over 80%.

Yeah and you need higher temperatures over 80%, so no charging above that. Again, if Samsung added a “don’t charge above that” there must be a reason. You’re not smarter than their engineers.

Higher temperatures to charge over 80%? That's new to me. I'm not disagreeing that traditionally the advice to prevent charging to 100% was sound. But with modern software maximizing battery life, there is no longer a need. If anything any benefit is just negligible at this point.

Additionally iOS trickle charges when temps get too high and also after about 85%. Temps aren't an issue.

Exactly, agree 100%

That’s weird about needing higher temperatures to charge above 80%.

My charger is as cool as a cucumber around that point forward.

Literally. Every day I see a post “so I charge my phone to 88% and when it gets to 26% I charge it to 92%” like dude what do you think you’re helping lol

It costs $99 to replace the battery in your $1000+ phone at Apple. I wouldn't worry about it. If after 3 years you feel the battery isn't lasting as long as you'd like, just get it replaced.

Use a 5w charger, charge over the night.
