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…

It would be better if it where user adjustable since they know what they need in their situation.

The solution is a battery you can replace, like every phone used to have. There aren’t only two solutions to this problem. (Technically you can still replace the iPhone battery, unfortunately it isn’t trivial like in the bad old days when phones didn’t have high def touch screens.)

> unfortunately it isn’t trivial With a good heat gun and toolkit, it's doable in anything from 15-30 min (more if the case is bent or damaged from falls).

That pretty much meets my definition of "not trivial".

In most Android phones (the ones I have used, at least), replacing the battery took less than one minute.

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.

The 2012 Nexus 7 is an outlier because it has especially bad flash controller - by 2015 most of the devices were unusable due to degraded flash. TRIM helped very little.

Other devices suffer from similar effects - not as bad, but most devices certanly lose quite a bit of I/O performance (especially writes) over time which makes OS run noticably slower.

> 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.

These are completely unfounded guesses. You have no basis upon which to determine whether it's "difficult."

It’s not a guess. Phones with removable batteries are thicker than “unibody” phones. Sorry but that’s kind of obvious.

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 had a Nexus 5 before which I replaced of about 2 years after buying it. Can definitely say performance improved after that (for a short while though as it was a cheap ebay battery).

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.

Agreed. I've been in 3 times. Every time I want to just pay for the replacement; they won't even offer the battery replacement if the diagnostic utility says the phone is good. My phone randomly shuts down or rapidly loses battery once it is below 40%. It's even worse when it's cold.

That's exactly what's happening to me as well. I think it shows a battery percentage based on (old) current voltage which dramatically decreases with low temperature, i.e. when you pull your phone from warm pocket in cold weather.

My 2014 MBA has recently started saying this, but I haven’t noticed any sudden change in battery life, I still get 5-6 hours.

It’s based on a certain number of charge “cycles” and not necessarily actual remaining capacity. When I was working as a “Genius” equivalent for an Apple reseller about five years back the number of cycles before that warning would pop up was around 500.

500 seems like a fairly low number to me, I'm surprised it's not more like 1000.

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.

>> Apple has decided that people want to buy razorthin phones I wonder what percentage people who buy those razorthin phones end up adding a millimeter or more to their phones by adding tempered glass screen protectors and cases over them. IMO, that defeats the purpose of the thinness.

Since I'm the most clumsy person of all time, I have to add these two things to any phone. It being pretty thin, it still fits my hand pretty good.

Seems like everyone is forgetting the #1 failure in older phones. With today's technology phones are very power efficient, the manage a rather amazing number of circuits with different functionality. Things like CPU, GPU, display, backlight, battery monitor, accelerometer, gps, compass, bluetooth, wifi, wan, camera, NFC, microphone, dsp, light senors, proximity sensors, etc. The vast majority of those circuits are sl…

This is very enlightened. As a consumer, I personally do not care so much for a modular phone, yet I do pretty much care about maintaining the same level of performance for my current device. Swappable batteries to increase performance is/could be a good selling point for modular phones.

EU should make a rule like that

> You can replace the batteries at both Apple stores Or you know, Apple could make it easy for the user to replace the battery by themselves. But they chose not to.

Know how I can tell you haven't designed any consumer products with a battery, replaceable or otherwise? This is the engineering equivalent of saying, "Why doesn't someone just go to the Middle East, sit down at a round table with with the Israelis and Palestinians and Sunnis and Shiites and rebels and Baathists and Saudis and ISIS members and refugees and all those other guys, and help them work out their difference…
