Phone is not an electric car. Capacitors are a feasible solution for momentary high load. Those phones just had tired depleted batteries and the proper thing to do was offer users battery replacement, not lie to their faces while upselling new model.
A high power workload on a phone might require ~5-10W over 100ms, i.e. ~0.5 joules. At 4V capacitor voltage, you would need ~30mF capacitor. Not likely to fit in a phone. This assumes you’re powering the phone solely off the cap. Even with a battery you’d still need something in the mF range to make up for the battery’s degradation.

Hi, Battery engineer here at an electric vehicle company. The crux of it is this: when you draw high current from a small battery, the voltage will sag (1). The manufacturer has an on-board battery management system that MUST turn off the battery if it goes below a certain voltage threshold. As the battery ages, the sag effect increases significantly, up to 2-3x. Thus, when your phone clearly indicates say 20% batter…
Again, it's not that Apple didn't violate the laws of physics on their "magical" device, it's that they: 1. Applied the throttling fix silently 2. Denied warranty replacements 3. Wouldn't even replace the battery with cash in hand until after the suit was filed 4. ..leaving people with no good way to have a working device.

The other option Apple had here was notifying people their battery was bad, not hiding the throttling, and letting people buy new batteries for a reasonable profit.
It's not bad though, it's normal, and functioning as expected at that part of the age curve. You can avoid this by reducing performance for the entire time you owned the device so nobody noticed, I guess, but that's all.

All that tells me is that other phones aren't getting the most out of new batteries, and are instead limiting themselves to the performance of an old battery. But yes, I agree, they should have permitted replacements - in fact replacements should have been permitted at home. Batteries deserve to be user serviceable.
> All that tells me is that other phones aren't getting the most out of new batteries, and are instead limiting themselves to the performance of an old battery. That's only one possible explanation. Imagine two phones that can both draw 5 watts max. Phone A has a battery that can supply 5 watts brand new, and phone B has a battery that can supply 10 watts brand new. It's true that phone A is "getting the most out of…

#165Worth mentioning here is that this wasn't just about the "sneaky" fix for battery degradation, it was about doing this without notice , and having internal tooling that would deny a replacement (even at full retail price) if the battery was above an arbitrary health threshold (but still low enough to cause throttling). Before Apple changed their tune, if you read about this, and went into an Apple store for a replace…

Is there some reason to think that's the case? Batteries are pretty consistent technology, roughly equivalent across manufacturers and all sourced from a pretty small pool of OEMs. If that's the case I'd love to know more!

Your point was that throttling is better than not working. But that's a false dichotomy. Rather than throttle. You can show less charge. It's what other phones do.
Why would I want the phone to turn off sooner?

The issue is that Apple knew about the bad batteries* , denied it and discouraged battery replacement, thus leading to increased iPhone sales if users wanted a decent experience - defrauding its own customers. That's not good faith at all. That apologists keep talking about batteries but ignore the real problem smacks of a PR campaign. * We actually don't know if the slowdown was only for bad batteries - that's Apple…

Just a reminder to everyone in the U.S., it is illegal for a company to revoke an item's warranty if you open it up, have a third party fix it, etc. It's the exact same law that applies to cars: The Magnuson-Moss Warranty Act
If you're in a state where one-party consent audio recording is legal, it's a good idea to always record your conversations with customer service.

The alternative is that the phone shuts off spontaneously and reboots if power draw gets too high, which also degrades the consumer’s experience and looks a lot scarier and more obviously broken to most people.
Or slow the phone down and inform the customer their phone is running in "Reduced mode" or whatever due to their battery being old. It's honestly not that hard.
