iPhone 15 Models Feature New Setting to Strictly Prevent Charging Beyond 80%

CygnusTC said:
First setting I will turn OFF when I get my new phone. I want the max capacity always. I don't buy a car that can go 80 MPH to turn a switch to stop me going beyond 60 MPH. And this is from someone still using an iPhone 8 PLUS on the ORIGINAL battery. Doesn't last as long as it did but 6 years in and still getting almost a day battery is acceptable.

I used my 14 Pro Max regularly until just a couple of months ago. I did wired charging only. I filled it to 100% all the time and depleted it to around 10-18% regularly, usually after a day and a half of moderate use.

Once in awhile it would have rogue battery drain in a low signal area like my mom’s apartment, but not very often. It’s still at 100% battery life.

There was always something wrong from day one with my husband and oldest daughter’s 14 Pro Max and 14 Pro. They had a lot of battery drain and husband charged his conservatively and the kid is always running her phone on fumes. It didn’t make a difference and they’re both at around 89% or under. I don’t remember the exact percentages, but it’s more than we’ve ever seen after a year.

They run social media apps and apps for restaurants and I don’t. I think it’s no coincidence Apple recently cracked down and insisted developers optimize their apps.
 
I’m going to get iPhone 15 for this feature because I’m afraid the battery on my current iPhone will die prematurely. Wait…

Most people probably won’t need this feature but it is useful for some scenarios. I hope it gets a toggle in Control Center for quick access! Otherwise it might be more trouble for me to use than it’s worth.

So you are basically throwing away 20% of your charge life for some extra charge cycles a few years down the road? I don't get it.

I still don't understand. So, since it stops charging at 80%, that means that you only have 80% of your battery's capacity instead of the 100% capacity. So, as others have pointed out, you are losing out on 20% of your battery's capacity!

Is that correct?

Maybe others have responded with this already but not everyone uses 100% battery. So if you’re usually only using less than 80% anyway, might as well save some unnecessary battery wear.

Then why 80% and not 95%?

In lithium based batteries, 3.6V is nominal voltage, which ends up being around 80%. The last 20% to 4.2V is technically an overcharge.

Why did the industry decide to make the overcharge standard? It wasn't as big of a deal when all of these batteries were easily user replaceable and replacements batteries were cheap.

When I'd get a new phone I used to buy 1 or 2 spare batteries and a cheap charger and rotate the batteries.

im on an iphone x soon to be 15 and my battery maximum capacity is at 84% with 6 years of use. This is with me charging to high 90s or 100% almost daily.

Naw. The iPhone 15 and 15 Plus don't have the A17 Pro chip. It must be something built into the USB-C port... just like how iPhone 15 and 15 Plus can only transfer data at USB 2.0 speeds.

As a serious response, iPad has had Charge Management feature since iOS 11.3. It stops charging before it's full. iPhone will stop charging if it gets too hot and supports Optimized Battery Charging, which stops at 80% temporarily.

So there's absolutely nothing technical that prevents Apple from implementing this feature on iPhone 14 and older.

After all these comments... I think I'm starting to grasp the concept here.

You shouldn't charge the battery above 80%... nor should you let the battery dip below 20%

Basically... you should only use the middle 60% of the stated battery capacity to preserve the health of the battery in your $1,000 smartphone.

Do I have that correct?

🤔

Good to know. My launch day iPhone 14 Pro is now down to 89% after a mixture of wireless charging in the car and overnight charging (optimized) at night (with MagSafe mostly).

I'm probably going to try to forgo wireless charging altogether when my iPhone 15 Pro Max gets here and see how that affects battery health over the next year.

Nothing to do with wireless charging. My wife and I exclusively wirelessly charge. I’m down to 86% on my launch day 14 Pro Max, and she’s on 98% on her launch day 14 Pro. Something about some of these batteries is just bunk.

What is the point of any battery if charging past 80% causes excessive wear and tear. Same with EV’s. Just plain dump. I want the full capacity always, so develop battery technology that does that.

I did not come up with this analogy.

Think of a battery as like a balloon. If you keep inflating it to 80% over and over and over, it'll remain really elastic and won't damage it. Now, if you keep inflating it to 100%, you risk damaging it once you reach the upper limit.

So, it seems, that even if the 80% option is selected, the iPhone 15-series will continue to charge past 80%:

I just realized this, but this is strictly not on iphones, the thing is my watch will sit at 80% ALL DAY and not move. I called apple about this and told me it's a new feature that's better than optimized charging.
I thought my watch was defective because it wouldn't charge all the way. So since it was on the charger all night I took it off the charger and it was just sitting at 80% around noon.

Nice, hope this comes to macOS as well, where the OS will sometimes notice that you're constantly plugged in and stay at 80%, but it's really inconsistent. Just let me configure it!

I've been using this on my MBP for years - great tool! 3yr old battery still at 93% capacity. My MBP is my workstation - on for 8-10hrs every day - always plugged in.

How often do you update your phone?

I update annually (and turn it in, I don’t pass it down), so the fact that my iPhone’s battery health is currently down to 89% makes no difference to me, because I’m not trying to prolong battery life to extend the life of my phone.

This is a great idea for people who keep their phones more than a couple of years.

Annually, and my wife usually gets my old phone. I gave her my 13 Pro when I got my 14 Pro on launch day. It had 90 percent when I gave it to her.

She exclusively uses wired charging. That just reminded me to check her battery health, and it’s still at 90% after two years of regular use. She charges once per day, at night when she goes to bed.

Hmmmmmmmm….

This is like when iOS 16 finally introduced battery percentage icon for the notched iPhones but not the Xr, 12 mini, and 13 mini. Later they eventually got it in a software update, so we'll see.
 
I want this on my Apple Watch Ultra. I charge it rarely and randomly so the current Optimised Charging scheme doesn't ever kick in.
 
I hope people throw a lot of light on Apple for this. They tout environmental BS and then offer something that is designed to reduce battery wear but exclude other products so they WILL wear out faster. Hypocritical if you asked me.

Just like the older Apple Watches and the thumb finger click. They can’t innovate on hardware so they restrict by means of software. Really pisses me off.
