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?

Electric cars have fundamentally the same problem and Tesla decided to attack it by hiding some of the battery's capacity when the car is new. While the car might report to the user it is 100% full, it might only be actually 90% full. The battery can therefore lose a decent percent of its capacity before the user will ever notice the difference. This decision was made because cars obviously have a longer ownership cy…

Li-ion batteries also last longer when kept between 30% and 90%. Several car manufacturers don't let you completely charge or expend your battery for this reason.

I feel like more transparency would have been welcomed, but aside from that this is a "no win" situation, since you have to pick a winner: - Do you degrade performance but leave screen-on time relatively unchanged? - Do you degrade screen-on time but leave performance relatively unchanged? Most Android devices seem to do the opposite (lose screen-on time, but keep performance relatively unchanged). Different people w…

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 or 3rd party repair make all of this infinitely more difficult.

(It's not just screen-on time, a naturally expected decline in operating time. As the batteries age resistance goes up and peak currents decline, so in some circumstances the device would actually hard turn off)

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.

Sounds like a blackberry and we know how that turned out for them in the current market.

Sounds a bit like Fairphone (well, not the ugly part)

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.

Tesla, for example, encourages owners to not charge beyond 90%, and refuses you let you drive below some number, which is around 20%, that it hides from the driver.

The AppleCare itself lasts two years, but that’s in addition to the year you get by default. The two don’t run concurrently. Edit: no, they do run concurrently. See child post. GP’s edited the reference to 3 years anyway.

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.

Hmm, you’re right.

I think my confusion was that Mac AppleCare used to be advertised as an additional 2 years (you could buy it as your standard warranty expired) but it’s now advertised as 3 years from device purchase too. Wonder when that changed…

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

It's not just you. Take a look at the google trends data for "iphone slow": https://trends.google.com/trends/explore?date=all&q=iphone%2...

I'm not sure that proves the iPhone gets slower with each update.

Whenever I announce an update my users suddenly become hyper-sensitive and start reporting bugs that have been present for weeks/months. I wouldn't be surprised if there's a similar effect here.

You are correct. derefr and tolien are incorrect.

iPhone comes with 1 year warranty. AppleCare+ extends that an additional year for a total of 2 years from purchase date.

From the site you linked above: "Every iPhone comes with one year of hardware repair coverage through its limited warranty and up to 90 days of complimentary support. AppleCare+ for iPhone extends your coverage to two years from the original purchase date of your iPhone and adds up to two incidents of accidental damage coverage, each subject to a service fee of $29 for screen damage, or $99 for any other damage, plus applicable tax. In addition, you’ll get 24/7 priority access to Apple experts via chat or phone."

Most Android devices have rather severe issues with flash degradation (due to use of cheaper chips, controllers and connection... cheap MMC controllers are still very standard) which makes them practically unusable after a few years.

Most? Absolute nonsense. The Nexus 7 have a small issue that was resolved when Google added TRIM support for Android. That was years ago.

I have a long history with almost every Android device. The device doesn't get slower, the battery life just gets terrible.
