Ugh - Cue the anxiety over battery over these forums. Honestly - these detailed metrics lead to so much worry.

A phone battery is a consumable. Use your phone as you need and replace the battery when it's done. It's like tires on a car - drive them until they need replacing, and get new ones when they are worn.
"I've had my iPhone for 3 months and my battery optimization is already 99.9%. Should I ask for a refund or stop charging it at night?"
 
There’s a post https://9to5mac.com/2024/02/20/iphone-15-battery-lifescyle-span/ claiming Apple has stated that iPhone 15 batteries won’t wear down as fast as older models.

TLDR: All iPhones 15 will retain 80% capacity at 1000 cycles in contrast to older iPhones going down to 80% at only 500 cycles.

I.e., batteries in iPhones 14 and older will lose their capacity at about 2x the rate that iPhones 15 do.

Seems to me that the iPhones that need all these extra battery features the most, like the 80% charging limit, are the iPhones that didn’t get these features.

I’d love Apple to do a sequel to that Mother Nature ad they did last September and then ask Earth what she thinks about Apple not letting all iPhone owners decide if they want to prioritize long-term battery life over more battery life short term.

Pretty weak imho.

Why can’t the peasants who didn’t upgrade to iPhones 15 join in on replacing their iPhone batteries a little less frequently?

Bad example though.
We can replace the tires ourselves and no need to tear the car apart while also risking to void the warranty.
I miss the good old days where I can just take out the battery and replace with another one.
Can? I'm going to say that a large majority (90%+ ?) of the population does not have the ability (skill or knowledge) to replace a tire on their own, not when an estimated 60% of the U.S. population doesn't even know how to change a flat tire.

Plus, you need special equipment (tire changing and tire balancing machines) to replace a tire.
 
Sure, but you don't needlessly wear your tires out. You measure their tire pressure and take care of them. Having this information is good. It seems more like a "you" problem if you check your battery cycles as a nervous habit.

Fair point, but I don't actually care about this. I just use my phone as I need to. With iPhone 15, I now use the option to charge only to 80% when I'm not traveling, but otherwise I try not to think about it. I do wish they were user replaceable because the main hassle of a failed battery is having to schlep to Apple to have them do it.

My iPhone 13 Pro was down to ~82% when I sold it after two years. I only know that because the buyer wanted to know. It felt fine to me though - it still lasted the day and I charged it overnight. If it started to fail to get me through the day I would have spent the $100 and replaced it, or given the buyer $50 off.

The percentage battery health wouldn't have mattered. Apple should may be implement a traffic light scale e.g. Green - good, Amber - replace soon, Red - replace NOW.
 
I’m no battery surgeon. Would having the option to not fast charge and turn off wireless charging prolong battery life?

That would be a feature.

After 1.5 years or less with a 14 pro, only having 80% battery life left seems steep compared to years past. Then again I think Apple like it when your battery dies sooner ;)
 
The battery on my 15 Pro Max is so good that I've had 80% limit turned on since I got the phone and have never gotten dangerously low.

It's mind blowingly good!
I don't get it. why limit battery to use only 80 percent of it to keep its max capacity over 80 for a longer period of time since I'm not using that extra capacity? I benefit all the battery life I have and even it's max.cap. gets down to 83-85 I'd still be better than people who limited it to 80 and wasted 20 percent of their battery capacity constantly.

It’s how long it stays at max charge. Just don’t leave it full when you don’t need it full. Same goes for low charge don’t leave it dead.
 
This is much like rotation lock being limited to one phone but not the next. The 3G, which I had, didn’t “support” rotation lock but the 3GS did :rolleyes:

Thankfully, jailbreak was my friend back then.

Apparently you don’t keep iPhones as long as some other people. One would want to maximize the time the capacity remains above 80%, assuming that that’s roughly the threshold of what is enough to get though the day.

In addition, percentage doesn’t reflect battery time consistently. Not every percentage point represents the same amount of time, nor does “80%” always mean the same thing. My impression is that an older battery with only 80% maximum capacity drains faster than a brand-new battery at 80%.

Just wait for the SSD NAND flash remaining life indicator that will come in iOS19. Its gonna get scary... there will be a status page in iOS... and it will be an anxiety inducing page of doom where your battery cycles, NAND cycles, port connector cycles, button presses, and OLED display life to half brightness will be reported :eek::eek::eek:
Would be actually cool to have access to such statistics.

Just more data for nerdy users like me. Not necessarily useful, but interesting.

The equipment to unmount and mount tires to a wheel and balance them is expensive and is not something 99% of people would have in their personal garage. Plus unless you've had training, it can definitely cause personal injury if not done properly. Apple can replace the battery for a reasonable cost and it can be done in around an hour if you make an appointment beforehand.

Yep, ever since the battery lawsuit years ago Apple has gone overboard with battery information causing the uneducated to obsess about their battery health. The Apple Discussion Community (ADC) is constantly bombarded by users raging that their brand new iPhone’s battery health went from 100% to 99% in a few weeks. Responses that educate about the fact that the instant a battery is put into service it begins to degrade are labeled as propaganda and accusations of planned obsolescence abound. And those same users think their iPhone battery should last at several days of heavy use. I’m not exaggerating.
 
Apple seems intent on not giving its customers an ability to extend battery life.

The 80% only being available to the iPhone 15 is a nonsens.

Apple doesn’t even allow advanced users to set up a shortcut or allow apps to control charging as well.

it’s a blanket ban. An 80% limit would be perfect for most people And probably extend battery life significantry, you could put your phone on charge all night with any qualms.

The question is, why?
Is there anything that prevents them from doing it on previous models?
It's not like this is such a killer feature that people would pick a 15 over a (likely cheaper by now) 14 or so if they're not already sold on a 15.
Exactly! Not adding this to older devices - heck iPhone's 12-14 models - is just a load of crock.

Whatever..it's silly. I spend a few seconds more grabbing the info off Coconut, or the true(ish) health from PowerUtil shortcut. Not griping, I do question the "battery health" of my iPhone 13 Pro Max. How this dropped 1, sometimes 2% every 10-14 days for months in 2022, then suddenly stop at 90% in Jan 2023. And it's STILL shows 90% 13 months later in Feb 2024..it's a bit odd. Ah well.

Consumable? True... But imagine having to take your printer back to HP to change the consumables in that.
Oh shoot, on second thoughts, I shouldn't be giving HP any ideas.

Very welcome change. Good to see all the battery information at one place.

Or imagine deliberately wasting ink in that printer just because. Nothing wrong with having some 'mechanical' sympathy for one's possessions.

It's probably part of meeting EUs new battery regulations, although it won't come into effect before 2025.
Maybe, they're planning on not selling older iPhones later in 2025.
