That sounds pretty fast, my 12 Pro Max is roughly the same age and at 96%

What's usually missing from these comparisons is how long people are actually using the phone and how they handle the battery. Mine is an iPhone 7 I bought refurbished back in February 2017. This phone is likely to have seen less use than a friend of mine's phone bought at the end of 2021. It spends 95% of its life connected to a power source (even when I actively use it), so I expect the battery to last quite some time.

  > What's usually missing from these comparisons is how long people are actually using the phone and how they handle the battery According to my phone, over the last 10 days I had an average screen time of 3h34m per day. I use it to communicate and to consume media while commuting. I charge it whenever it needs some juice, it does get to down to 10%-20% sometimes. But honestly I don't see how my usage can hurt it so much. And if my usage is indeed what damages the battery so much, then that seems to be Apples issue, considering how I'm really not a poweruser or whatever. What battery health does your phone have? I can't imagine that having a phone connected to a power source 95% of its lifetime can be especially good for the battery.

    Letting it go down to 20% before charging it back up means the battery has to cycle, and as I understand, that's what "ages" it. And managing that is on you, it's not Apple's fault that you won't (or can't) plug it in. What can be Apple's fault is the battery going to 10% after using it for 3h, but I don't think that's the point here.

      I'm sorry, but how can it be my fault for using a device until it's battery is low-ish? > Letting it go down to 20% before charging it back up means the battery has to cycle Apple actually says themselves, that "You complete one charge cycle when you’ve used (discharged) an amount that equals 100% of your battery’s capacity — but not necessarily all from one charge." [1] The iPhone 12 mini has a 2,227mAh battery. Its battery health is at 86%, so effectively I have 1915mAh. But now you're also telling me that I can't use it past 20%, which leaves me with 1530mAh, or 68% of the original capacity. I can totally agree that with long-term usage it's up to the user to optimize their battery usage for health. But my device was at 92% battery health after not even a full year and I simply won't accept that this is on me. Especially if we consider how expensive and complicated Apple makes it to replace a battery. Apple also tells me that I can charge my battery whenever I want. To give more insight, GPS is fully disabled 99% of the time, it runs in dark mode, auto-brightness is disabled and I usually set it to a pretty low brightness, 5G is disabled and generally I remember disabling lots of things like "double tap to wake screen", "lift phone to wake screen" etc. [1] https://www.apple.com/batteries/why-lithium-ion/ https://www.apple.com/batteries/why-lithium-ion/

        That's not at all my point. Whatever time it spends unplugged, is time spent draining the battery. Down to 90% or down to 0%, it's just a difference of amount. If you keep it plugged most of the time, and only drain it to, say, 90% (and this is an arbitrary number), you only used 10% of one cycle. If you let it unplugged until it's down to 0%, you use 100% of one cycle. If every day you let it go down to 0% and then charge it back up, in 10 days you've used 10 cycles. If every day it only loses 10% (total) and charge it back up, in 10 days, you've used 1 cycle. I'm not saying "it's your fault" or that "you shouldn't do it", I'm talking about objective use of the battery. Yeah, I know it's a mobile phone, so one of the reasons for buying that is to use while out and about. But the point is that not everyone uses it that way, which can explain why some people see the battery health going down faster than others, on the same device. And that's not Apple's fault. Sure, you could argue that the battery life is ridiculously short, that the battery's health shouldn't degrade as fast, and so on. And I'd agree with that. But still, it's a different issue.

  Being constantly charging is actually bad for the battery life. Being around 100% stresses it… so that’s why some Apple devices now try to determine how much charge is needed and keep it at 80% if possible
  - vladvasiliu 4y ago
    It does. But does it stress it more than charging to 100% then draining it to, say, 10%, then charging it again? Hence, racking up cycles at a faster rate? I know it's anecdotal, but I mostly keep my battery-powered electronics plugged-in when possible, and their batteries tend to degrade much less over the years compared to a friend's, who tends to unplug them and charge them when needed. And the electronics in question are fairly similar: iPhones and same-gen Macbooks. Same for my work laptop (hp) which, after 4 years, still has around 80% of its original battery life, when my colleagues', who use them much more often on battery, only last around 50% of their new condition, if they weren't changed because of swelling. The one kind of battery among mine that seem to have shorter lives are camera batteries. Which, of course, tend to get drained more since I don't have an outlet handy when out in the woods.

    1.5 years old 12 Pro, 83% battery health. But I mostly do iOS software engineering, so the device spends most of it’s time plugged in. In a few months, it won’t even need to try to stay under 80% anymore. It just will.
