I am a user of Samsung Galaxy and Apple MacBook Pro M1 Max. Both models offer Battery Limit/Battery Protect features to protect the lithium-ion battery. I first realized that other iPhones, except for the iPhone 15, don't have such a feature. Maybe it's a good idea to include it?

I have an iPhone 13 mini as my "work phone "and it's indisputably a fantastic, efficient, small phone. However, I am kind of OCD about keeping it between 40-80% charged, which is a lot of manual toil. Conversely, I also have an Android Galaxy S22+ for my personal phone. The "Battery Protect" feature limits charging to 85%. Life is easy with this device and it causes me a lot less anxiety. Really now, why can't Apple…

Why?

How is that possible? Even charging my phone to 80%, I can still use it for at least a day. Although my laptop does get a lot more use.

it depends on how you use your phone. when i am outside all day running errands, checking messages, calls, web searches... by the time i get home my phone is usually on the last % before shutting off. i tend to buy cheaper older models of phones though, that may not have the strongest battery to begin with.

I buy cheap android phones with large batteries, it's pretty much my only criteria nowadays because everything else is good enough for me.

The only time I get close to running out of battery is when I'm watching YouTube videos on a long bus/train/plane ride.

I have an 11 pro as my main workhorse. Multiple years old, constantly running the battery to 2 % then charging to 100 and it still lasts all day for me. I feel like the concern I see going on in this thread might be a bit misguided.

My 11 pro was the same way. And then I got a 14 pro.. it has noticeably worse battery life, I suspect in part due to 5G which I have since disabled. I tend to keep it on the charging stand on my desk for video calls as it now has magsafe (or whatever it's called). It's constantly charging to 100% and I'd love to have a way to stop it from charging without having to remove it from the stand like a cave person.

Apple doesn't really care about their iPhone customers. They prefer milking them for more money by forcing them to buy a new model instead of adding a feature that would actually help the environment which they often lie they care about.

I just use my phone. The battery can be replaced.

Sure, as long as you don't mind messing up / sacrificing the IP69 waterproof seal integrity. Ask me how I know *cries softly* .

I actually don't terribly mind that, mainly because in almost 15 years of owning a smartphone I've never dropped one in the water. I feel pretty comfortable not having waterproofing as a result.

Glancing at some comments here mentioning the overnight charging feature working for them, am I in the minority by charging randomly whenever it needs it? My charger isn't even in the bedroom. Curious how my random on/off habits compare to overnighters in long term battery health. I try to take it off around 80% so I was interested in this feature and confused when the update didn't include it. I don't like that it's…

The world of lithium-ion battery chemistry is quite complicated, but in my experience, the top contributors to battery wear-out are, in decreasing order of severity:

- Charge cycles (including partial cycles, e.g. 100% -> 50% is half a charge cycle)

- Depth of discharge (deeper discharge cycles are worse)

- Extended periods in hot conditions (over 40 degrees Celsius)

- Extended periods of being held at 100% state of charge

In essence, your charging behavior dings the first two items: higher number of charge cycles, and deep discharge cycles. If your goal was battery longevity, keeping the phone plugged in as much of the time as possible would be the best strategy. Bonus points if your phone supports a "stop at 80%" mode, but still the winner even without this feature.

Well, I really like a nice bath at the end of the day. Different strokes and all that, more power to you bigstrat.

I can't imagine caring about this honestly. The way i feel it is like constantly caring if your white shoes are dirty, i only trust my shoes to help me walk.

Technology should be as transparent as possible in my opinion and not bring us back to thinking about said technology, just what we can do with it.

It's tiresome enough to worry about having a charged phone, i couldnt bring myself to look at battery percentage or even phone charger options just because i am calculating how long will my phone last in the long run.
