As pointed out above, this is already the status quo (replacable battery, 1 year life, etc). Tile has had it for years.
I'm curious if it would've been technically feasible to have wireless charging on these instead of replaceable battery. Or would that greatly increase the price?
Yeah, I had to check their website... it looks like some of the their models have replaceable batteries now, but they certainly didn't start that way (and not all of their products have a replaceable battery today).
> Conspicuously absent from the list [of third-party products using the Find My network], of course, is Tile. Given their membership in Epic’s Coalition for App Fairness, I wouldn’t hold my breath waiting for Apple to promote Tile’s products. And it’s unclear to me whether Tile even wants to be in the Find My app — their spat with Apple is more about their own app competing with Find My, and their accusations that Apple unfairly advantages Find My by not holding it to the same rules as third-party apps that ask for always-on location access. Apple’s solution is this third-party accessory program; Tile’s preferred solution would be Apple allowing Tile’s own app to do everything Find My can do.
Tile didn't start with replaceable batteries--they still don't use them in all their products. I don't know how AirTags will be in practice, but user-replaceable batteries haven't been great. I don't know if it's a technical restriction or not, but "low-battery" seems to be a time based warning and not based on battery charge. So I either get an alert when 1 year has passed on all of my devices at the same time, or they just suddenly die without warning. I could see why Apple might avoid this user experience. Hopefully, their implementation is better.
> I don't know if it's a technical restriction or not
More likely because CR batteries don't drop voltage significantly as it discharges. And at full discharge it suddenly drops dead. Which is why it's harder to measure "remaining charge", as that's generally calculated on battery voltage.
It's equally hard to get any useful information about Li-On or Li-Po based just on battery voltage which is why any actually useful battery indicator involves a charge counter (informally known as a 'gas gauge'). The actual coulombs of charge are counted in and out and that gives a much better estimate.
Lithium batteries are high output until they're not. Like the CR2032 battery in my car keyfob it's working until it's not. The drop from 3V to 1V is precipitously fast. Also, 1 year is extremely conservative. I normally get 3 years out of these batteries. An Airtag that's constantly being interrogated may run out faster than say a keyfob used 5x a day
If the airtag dies without warning, wouldn’t it alert the user that the tag is out of range, and so then they could replace the battery? (Presumably Apple has a UI flow for this.)
Even for lithium ion batteries, notoriously hard to track, that's only true for the middle 70-80% of the charging range. It's very easy to check it a lithium ion battery is almost empty, just wait for the voltage to drop below 3.6 or 3.5 and maybe adjust for temperature.
For a CR2032 specifically, you get a nice smooth drop over at least the last third to quarter of its charge. There's no difficulty in detecting that.
It sometimes looks like that in the lab, but in real life it doesn't work. Here are two of the MANY situations that result in incredibly misleading voltage readouts:
My battery is 80% charged, and then I go outside where it is 10 degC colder. Suddenly my battery voltage drops by 200mV and my battery looks 20% charged
My battery is 80% charged and then I start playing a video. The increased load drops the battery voltage and suddenly my battery looks 20% charged.
The fact that the Nest motion sensors / path lights in my home have been functioning for almost 2 years (their stated lifespan) without me needing to replace their tiny batteries boggles my mind.
A CR2032 (disposable) has 2x-4x (200 mah under ideal conditions, compared to 40 mah) the capacity of the same sized LR2032 (rechargeable), and is more stable over a long period of time. In addition there is the necessity of additional charging circuitry, and I'm not sure how small they can physically make the charging antenna.
Lithium rechargeable would mean higher price, larger size for equivalent specs, with an added risk of fire!
Yeah but is that practically the case? Most people just chuck things in the trash. Most are too busy to even think about disposing of their waste properly..
This is the reality of our society
you could get them as a re-chargeable (though it would likely be more waste to buy a recharger) - but I mean even rechargeable batteries are also consumables
To be fair, replaceable batteries in laptops and phones also used to be the status quo and Apple successfully changed that. Just because it’s the status quo wouldn’t prevent Apple from “thinking different”.
I feel like this gives far too much credit to Apple. Any one company can "think differently" but Apple shouldn't get the blame for all of the other companies following suit.
Remember the ads Samsung ran before axing the headphone jack a year later?
I do think it couldn't have happened without Apple doing it first from the big manufacturers.
Apple had (and still have) the status and prestige to do anything and make that a standard. If Huawei/Samsung/etc didn't include chargers, didn't use USB or USB C, changed from 3.5 to some proprietary audio jack first, they would have been ridiculed.
But once Apple changed these things (except luckily the USB), these companies could point out that "Apple does this, so it must be an acceptable idea".
The most annoying thing about this is that they are trying to spin these changes as innovation or something for the environment.
Apple has an ability to drive change that other computer manufacturers don’t.
The simple reason is that Apple is the only manufacturer in a specific market. The market for MacOS (or in the case of iDevices, iOS) users.
What that means is that Apple can introduce a pretty shitty change and not lose too many customers to other manufacturers because switching from Apple to another manufacturer is much harder than from Dell to HP.
So, for example, if Dell were to introduce those shitty butterfly keyboards, that were nearly unusable and got spoilt so easily, they would have to change back to their old keyboards within months, unlike Apple, which managed to stick to that design for years and generations of devices without suffering too much.
I use that example because it was an unambiguously worse option, so it nicely illustrates how Apple has a lock-in that others don’t. But Apple can use that lock in to then introduce what are potentially more useful changes (USB2) and/or changes that are not fully baked yet (USB-C), and not suffer the consequences other manufacturers would.
As a customer, my buy-in is built on the trust that the majority of the time the company is going to make the right call.
If they make the wrong call, they’ll handle it. Or they won’t and you’ll get burned a little bit.
When Apple makes an obvious error, like with the keyboard, or something external is holding back the quality of the product (recent pre-Apple silicon laptops) you do have to sort of pay attention and if possible steer around the problem.
As an example I largely sidelined the weak 2018 MacBook Air and instead invested in maxing out a Mac Mini. That turned out really well for me.
Sometimes, like with the butterfly keyboard, it feels like Apple does not take enough responsibility for screw ups and take greater measures to make customers whole.
This happened recently for me with the iPhone 12 Magsafe Silicon case, which is a good product but flawed in the context of the iPhone upgrade program.
In that way, I think Apple could and should be much more generous about returning value to its customers instead of to shareholders.
If there were any existential threat to Apple, I’d say it’s the need to reward shareholders instead of customers.
Speak for yourself. The butterfly keyboard is the only laptop keyboard I have ever encountered which I can type on for a full day without flaring RSI. Despite having a fully-loaded 16" with the replacement keyboard, I still use the 4.5-year-old butterfly model for almost everything.
> What that means is that Apple can introduce a pretty shitty change and not lose too many customers to other manufacturers because switching from Apple to another manufacturer is much harder than from Dell to HP.
I totally get this interpretation, but I genuinely cannot work out how to tell the difference between this explanation and the alternative explanation that this actually just is what the smartphone market prefers and when given the choice they will choose it.
That would also explain why essentially all competitors copy the change one product cycle after the first company makes the change. Unless you’re suggesting that Apple’s competitors are actually colluding with Apple to remove the headphone jack despite strong market opposition, I really don’t see how you can definitively say that Apple and its competitors aren’t simply making products that most people prefer.
As someone who has mostly had android phones (but not now), I watched the wireless charging thing unfold in a hilarious way.
A bunch of android phones had wireless charging years ago, including one of the nexus devices IIRC. Great! I'll buy a couple of wireless charging pucks and use them. No more flakey USB ports that give up before the phone does.
Apple didn't pick it up.
Android phones all dropped the feature.
Apple picked it up, hyped it, rolled it out.
Android phones started appearing with it again.
It's like Apple has to lead the way, and even useful features can't survive in the android ecosystem without Apple's blessing.
Afaik Samsung phones had wireless charging since 2016 and kept that, didn't they? I'm an iPhone guy, but my colleagues were using wireless chargers around that time.
Interesting ... looking up the specs the site I use tells me that was "market dependent", I wonder if that has impacted my experience.
The motorola Nexus 6 had Qi charging in 2014, then that manufacturer seemed to back away from it. Huawei only picked the feature up in 2019 AFAICT, my P20 pro didn't have it.
But yes, it does look like the galaxy phones have had it all along. I wonder why I discounted those?
It wasn’t status or prestige. It was developing battery conditioning software and integrating it in the OS so the batteries could last years before replacement.
And when Apple did this, they were able to pack more wattage on their MacBooks, making them last substantially longer on a charge than competitors. Competitors had to do same to eventually catch up.
> these companies could point out that "Apple does this, so it must be an acceptable idea".
Friends and jumping off bridges and all that.
I get that Apple has immense sway in these marketplaces but I've never gotten a good explanation for why it's Apple's fault when another company makes that same anti-consumer decision. Headphone jacks being the most prominent example.
I didn't blame anyone, I was just saying it couldn't have happened without Apple doing things first.
And not even all the things I listed really annoy me, I have listed examples for things where Apple had to be the first from the established manufacturers. For example the audio jack, I basically never used wired headphones in the last 6 (?) years (since the first time I bought Beats with Bluetooth), so I don't even care.
> I do think it couldn't have happened without Apple doing it first from the big manufacturers.
Well sure nothing “could have happened” without the first company doing it and then the rest of the companies also doing it. But you can’t blame just Apple for an industry wide change. Sure they where the first major company to push a single button mouse, but you can’t blame them for there being no two or three button mice on the market today. That’s not something they made happen, that was an entire industry adopting their practice, and the consumers backing that decision.
We can just blame all the companies for doing X, we don't have to be so selective. Apple and Samsung both removes user replaceable batteries? Well, screw both of them then.
Thankfully saner heads have prevailed at companies like Sony.
They solved the waterproof phone with a headphone jack many years ago, went with with the craziness of removing it for no reason reason like Samsung and apple, and have since put it back in all of their phones as there hasn't been any noticable improvement in phones that have removed it, but now you have to make sure your headphones are charged.
> Apple shouldn't get the blame for all of the other companies following suit
It's not about blame - Apple has repeatedly changed the landscape of computing for decades. Mac, modern laptops, iPhone. Downplay their influence if you will, but they have been the harbinger so often before...
Apple didn't actually invent the modern laptop; that's just Apple PR. The Xerox NoteTaker, Osbourne 1, Dulmont Magnum, Toshiba T1100 and Compaq SLT all get credit for the “first” in different ways – and all in the 80s, before Apple produced a single computer that could be called a “modern laptop”. (Except the NoteTaker, which was 70s.) I vote the Toshiba T1100 as the first modern laptop, btw.
Apple was the first to put a trackball in a laptop (though that laptop was, in the rest of its design, at least five years out of date – hardly modern), invented the laptop palm rest, and – much later – was the first to put an Ethernet port in.
Turns out all the people up in arms about the headphone jack didn’t really amount to much more than media fervor.
I really like the look of this over the tile products personally and it’s “rightly sized” to me. I definitely will see myself owning a few of these air tags
They are replaceable just not user replaceable though user's can change it if they buy $10 worth of tools. Just like my car's battery isn't user replaceable unless i buy tools to be able pull the battery out of the battery compartment.
Your car's battery isn't glued in place behind a cover held by screws with an intentionally obscure pattern. Not to mention, car manufacturers don't (yet?) use specialized batteries that only they can source legitimately nor use DRM to make the car reject a perfectly good battery just because it's not the original one that came with it.
I've never changed the battery in my IPhone but my MBPr 15 it took an OEM battery fine. I cut the glue with some spectra fishing line and wasn't that hard. Took me about 15 minutes to replace it. The IFixit OEM battery came with the tools to change out the battery.
Older iPhones are much the same; I've done several battery and screen replacements on my 1st gen SEs. A heat gun comes in handy, but beyond a couple cheap screwdrivers most of what you need is just decent eyesight and steady hands. (I only have one of those, but can still fake the other for a few years yet before I need one of those magnifier visors.)
Newer ones, I don't know. It does look like Apple is starting to move in truth toward the hostility to DIY repair they've always been claimed, in the past often falsely, to display.
It's a shame. I really like the idea of that purple 12 mini - it'd go so well with my fountain pen! But if I can't fix it myself when it needs fixing, that's a much knottier problem.
My next car’s battery will be glued in place, permanently affixed to the frame. When it dies after a million+ miles, I’m sure both battery and steel body will be quite ready for recycling.
It wouldn't, but in this specific case they didn't. Did apple bring any actual innovation that I missed? That's why I was proposing wireless charging, that would've actually been a nice step forward.
> Did apple bring any actual innovation that I missed?
I guess it depends on what you think of as innovation. Their marketing pointed to "scalloped" batteries instead of square so they can take up more empty space (plus the space that would have been used by covering the battery and a fatter connector).
In my experience, their batteries went from 200 charge cycles, about ~4 of battery life, and often failing before reaching it's end of life to 1000 charge cycles, about 8-10hrs of battery life, and rarely getting "service" warnings suggesting replacement. At least last time I needed to swap batteries I just needed a small screwdriver.
I was very concerned when they ditched removable batteries because that was one part I constantly had problems with. Since those issues were address I'm very glad they went that way.
However, none of this justifies intentionally making the batteries extremely difficult to replace. It wouldn't make any noticeable difference to their bottom line (when you consider the margins on their products) to hold batteries with a screwed-in bracket (or even by compression with some foam) instead of hard-to-remove adhesive.
Adhesive responds better to thermal expansion/contraction cycles than screws. Using foam to compress the battery to hold it in place can prevent safe thermal expansion and isn't necessarily going to hold everything in place with vibration or percussion.
Phone batteries stopped being user replaceable once smart phones started improving at such a rapid pace that even if you could replace the battery in your 2 year old device you won’t want to because the UI would be dog slow and the camera a blurry mess compared to current model.
Funnily, the time for replaceable batteries in phones seems to have arrived, but users are now trained not to expect it.
Sending your phone in for a manufacturer battery replacement after 2 years of use to get a further 2 is a good compromise in my view. My last replacement was about $50.
Why is that the requirement? The extra layers of plastic to enable removable batteries cost close to zero dollars and don't have to cost more than a millimeter.
There’s also connectors that wouldn’t be there normally, those connectors also have to be large enough to support the current. Then there’s the plastic lined battery well, as well as the plastic battery case. It’s not as simple as throwing plastic around a battery and calling it a day.
> There’s also connectors that wouldn’t be there normally, those connectors also have to be large enough to support the current.
Supporting 5-10 amps requires very small pins. It's a tiny percentage of the battery size.
> Then there’s the plastic lined battery well, as well as the plastic battery case. It’s not as simple as throwing plastic around a battery and calling it a day.
Yes, those are the layers of plastic I was talking about.
I didn't say you could slap something together in half an hour, I said it would cost close to zero dollars when talking about the per-phone price.
> Why is that the requirement? The extra layers of plastic to enable removable batteries cost close to zero dollars and don't have to cost more than a millimeter.
That very last phrase you said a millimeter. None of this will fit in one millimeter, which was my counter.
The connector won't affect thickness, it will go at one end of the battery.
For the layers of plastic, the battery already has a wrapping, and the phone already has a back. You just have to reinforce the wrapping on the battery. How much thickness do you think that needs? It's definitely not five millimeters.
“ The extra layers of plastic to enable removable batteries cost close to zero dollars and don't have to cost more than a millimeter.”
“It’s two lines of code, how hard can it be?”
More seriously, the cost of designing a battery pack goes way beyond that, just like in software there’s a world of difference between an internal and an external interface. Adding ESD protection for instance can be a headache.
There's an enormous amount of design cost in a phone no matter what. Doing it differently from the start does not substantially increase the cost, and I'm not asking for a retrofit.
It's absolutely bonkers to suggest a 20-30% increase in total cost that would be driven by design costs; that's more than doubling the entire design budget!
I'm not talking about NRE costs, I'm talking about very real manufacturing costs that you are ignoring. Modern battery packs are one of these things that if you haven't designed one you tend to think they're simple, but have a lot of hidden complexity.
Just as an example, modern batteries require keeping track of a lot of parameters and metrics, and require keeping control of things like cell balancing. Making a battery removable means having to move all this into the pack, which then implies having exposed critical interfaces.
As an example check this device by Texas Instruments: BQ40Z50-R2. This gives you a lot of the functionality to the point that Apple keeps variants of them in current laptops, even if they're not removable anymore.
To make a software equivalent, imagine building an enterprise product that connects to a database, and then being asked to have this link exposed through public APIs. Now you need to consider delightful things like authentication, or being vulnerable to DDoS.
1. That just moves from phone to battery, doesn't it? That's not a cost increase for the bundle.
2. You don't need fancy things like cell balancing for a phone battery.
3. Even with this chip it's $4 BoM for small batches and significantly less in bulk. So that could be a 1% cost increase. So we have that, a thin plastic shell, and a tiny connector. How are we hitting 20-30% increases, hundreds of dollars?
1. Except now you need a new PCB, a new subassembly, new procedures...
2. You need a lot of fancy things, just not cell balancing. That “battery health indicator” all iphones have, guess where that’s from.
You can take it from someone who has built several devices with replaceable batteries, or we can just keep debating until I’ve fully explain to you how you actually build one of these.
The thing is, I don’t want to waste more time on this, you can do your research on your own, or just keep your preconceptions, whatever floats your boat.
> 1. Except now you need a new PCB, a new subassembly, new procedures...
Every phone needs new subassemblies and procedures. For the PCB, you end up with an extra one that's tiny true.
> 2. You need a lot of fancy things, just not cell balancing. That “battery health indicator” all iphones have, guess where that’s from.
Sure, okay.
> You can take it from someone who has built several devices with replaceable batteries, or we can just keep debating until I’ve fully explain to you how you actually build one of these.
> The thing is, I don’t want to waste more time on this, you can do your research on your own, or just keep your preconceptions, whatever floats your boat.
Where would I look?
I'm trying to follow your logic. But you mostly keep naming things phones already have. They already have all this engineering work. They already have the battery chip, it just changes location. And that chip is less than $3.
Could you please give me a couple sentence explanation of how you arrived at 20-30% for a phone that's designed from the start to have a removable battery? You keep nitpicking me for not understanding an argument that you never explained!
My understanding goes something like this: Posit a $600 phone of which $50 is the battery pouch. Remove battery pouch and chip from phone, replace with a connector, phone now costs $550? Add plastic shell and $3 chip and connector and tiny PCB onto the battery pouch. For the total price to rise 20%, doing that has to cost more than $100 and leave you with a battery that costs more than $150. How?
And phones didn't get massively cheaper when they stopped letting you remove batteries...
On the cusp of the transition, I attended a music festival with a couple of friends. They both had modern smartphones, I had something closer to an old-school feature phone. At some point on what was probably the first day, we all went to the phone charging tent. They stayed there for an hour or two with their phones plugged in. I walked in and walked back out again immediately, with a fresh battery for my phone handed over to me for free.
I do like having a thin phone, but the utility of a replaceable battery has been sorely downplayed over the years.
Hopefully MobileQubes [0] or similar competitors become more prevalent, there's a convention I go to where the hotel has had these kiosks since 2015. You pay ~$5 to rent a fully-charge external battery for 24 hours, with whatever connector your phone uses, after which you return it to the kiosk. If you fail to return it you're automatically charged the "buy" cost.
Yeah it's not free, but it's really nice if you underestimated your battery life since you're not tied to a single spot while charging it.
Replaceable batteries were superseded by batteries of sufficient capacity for 99% of users. (And for the remaining 1% I'm sure the non-Apple marketplace has fantastic, no-compromise solutions.) Remember when it was impressive for a laptop to have three real hours of productive battery life? Back then, most laptop batteries were trivially hot-swappable. Now it's normal to get eight or more hours of productive use from a laptop battery.
I realise that capacity is theoretically orthogonal to swappability, but functionally it's relevant because battery casings, compartments, connectors and chassis strengthening elements all take up space that could otherwise go to a larger battery pack.
Tile has user replaceable batteries on some of their products. Granted, it seems to be on their best sellers, but I somehow ended up with the thin ones, and I found out those don't have replaceable batteries after they died.
Do you have a source for that? My partner got a me some Tiles for my birthday 9 months ago and I still haven't gotten around to actually putting them on anything, would hate to find out they're only good for 3 more months

The battery is slowly discharging and dying sitting in the box. I got one as some vendor swag a few years ago at an event. I stuck it in a drawer for a couple of years and forgot about it. When I went to move, I tried using it. It was dead.
They chose to set it up this way, and also that's not even close to the normal shelf life of an unused battery, so it must be actively draining it and not "how batteries generally function".
Not only price, but size/weight too. It seems that currently the thing is 99% battery/case/PCB and is designed around the battery. While technically wireless charging is off-the-shelf, incorporating that may have been seen as "too expensive" and/or "too large".
I'm curious if it would've been technically feasible to have wireless charging on these instead of replaceable battery. Or would that greatly increase the price?
