Curious if you have a source on that? I see otherwise here: https://www.apple.com/support/products/iphone.html I bought a new iPhone about 48 hours ago and was told the same thing as shown above.

In fact, both are true. It just depends on where you live. What he said is the case within the European Union due to some EU law regarding warranties. I believe in the EU an extended warranty like AppleCare only goes into effect after the original warranty has expired. There are also statutory warranty periods of a year (I think) for devices like the iPhone. In the United States, on the other hand, AppleCare replaces…

As you say there could be some legal jiggerypokery but Apple claim it's still only two years for an iPhone:

> Up to 2 years from date of purchase for Apple TV, iPad, iPhone, iPod, Apple Watch or Apple Watch Sport

With the price of iDevices rising there's probably a "reasonability" court case brewing where someone argues that a £1200 iPhone X should last longer than 1/2 years.

Edit: https://europa.eu/youreurope/citizens/consumers/shopping/gua... says the default statutory warranty should be 2 years. What a mess.

This post is written as if it wasn't Apple that introduced the hard-glued battery. They made a consumable hard to replace and backed themselves fully willing into this "no win" situation. And now they are not being forthright about the tradeoffs they made and certainly aren't making an effort to fix any of it. That is planned obsolescence. These batteries can be replaced but Apples absolute refusal to enable customer…

> This post is written as if it wasn't Apple that introduced the hard-glued battery. They made a consumable hard to replace As others have pointed out in this thread the batteries aren’t hard to replace; this is just not something you can do directly as a user. That probably makes sense; it’d be difficult to make a super-thin smartphone while at the same time provide an easy way to replace each part.

The problem isn't necessarily the replacement, even though it's certainly not for a large majority of iPhone customers. The problem is sourcing the battery in the first place. Apple certainly isn't supplying any of them.

In the best case you get one that works properly, if you're unlucky you might get one that has lower capacity, and if you're very unlucky you might just get one that puffs up and catches on fire.

There is absolutely no evidence that Tesla is doing what you say. In fact, if they were, this curve https://images.hgmsites.net/med/tesla-model-s-mileage-vs-rem... would stay at 100% for a while instead of immediately dropping.

Yep, it looks like you are right. I was passing along second hand information that I never bothered to verify. After some Googling I learned apparently Tesla only hides capacity at the low end to prevent a user from being stranded. The default settings also prevent charging to 100%, but that is fully transparent to the user.

Thank you for looking! I've seen this "Tesla sandbags at the top" repeatedly on HN but you're the first person to respond when challenged.

BTW the car won't actually let you drive at low charge, so yes, you can be stranded because the car refuses to damage its battery. That's why it comes with a towing service.

You can replace the batteries at both Apple stores and independent retailers. https://www.cnet.com/how-to/iphone-battery-replacement-diy-o... The issue IMO, is it's not obvious that the battery needs to be replaced and when. It's not holding charge > new battery is far more obvious than it's slow > new battery. Most people probably prefer a slow phone than one without charge however Apple should have some indication…

You really can't though. I had a phone with an awful battery-- it would shut off around 25% randomly. I brought it into Apple 3 times, it even had apple care-- and because the f *ing diagnostic suite identified the battery as good, they wouldn't replace it. They wouldn't even LET ME PAY FOR THE REPAIR.

Same here. I went to a 3rd party place and they replaced it cheaper anyway, with no problems.

How about a bigger battery? My primary criterion with each iPhone purchase is which has longest battery life.

Apple has decided that people want to buy razorthin phones and there is just not way to fit a large battery in there. I wish there were phones built like the old IBM thinkpads. Bulky, square, ugly but also indestructible and fully user servicable with replaceable batteries.

They offer bigger batteries in the form of the Plus and now the X.

They’ve obviously determined that it’s not worth it on the regular iPhone. I guess their surveys and stuff show that their customers would rather have the thin phone, on the whole.

Another idea: Apple could pop up a dialog at a certain point saying your battery is sub-optimal (but not doomed) and you should replace it for the best experience. I’m sure that would go over GREAT.

My 2011 MacBook Air has been saying this for YEARS

I know they do it when the battery gets really bad, they could move it up to happen sooner. I just imagine it would fit into the planned obsolescence narrative too easily.

How do non-apple devices cope as they age ? Any word on what Nexus, Galaxy or Pixel devices of a similar vintage do? does the performance stay the same but the battery life becomes shorter?

I have a Nexus 6P and its battery is going bad. It just shuts down when it reaches 20-30%. Kind of annoying because I never know quite how much battery life I actually have remaining.

I have a similar situation.

My Android (1st Gen Moto G, running Lineage OS, about 3 years old) shuts down once the battery level hits 15%. You can actually see it change from 15% to 1% for one brief moment before it shuts down.

Sure, the battery is old, but this behavior is unlike the behavior of any other OS/device I've seen. I've seen some laptops with seriously messed up batteries and as far as I can remember, the OS reports a smooth discharge profile without steep drops and without and strange "surprises".

I think Android is probably not taking battery health into account when it reports remaining capacity, but that is only a guess.

Interesting that the battery aged extremely fast when iOS 11 got installed and took the performance down to the „really unpleasant“ level.

It's just an artifact of data. The data from iOS 11 is naturally going to be collected when the phones are older than iOS 10.x, because iOS 11 came out later (and because people are likely to only run geekbench when they get their phone or do a major OS update, rather than, say, running it on iOS 10.x immediately prior to upgrading to 11).

I have an iPhone 7. Run a test "Antutu benchmark" (The phone was connected to power) and it got "127823", according to their ranking, it should have "160864". 20% less. I would like to know, if this is the case or just coincidence.

I have iPhone 7 as well (almost year old) and got 156,473
