All iPhone 11 Models Feature New Dynamic Performance Management System to Reduce Impacts From Aging Batteries

No offense taken. One instance posted as requested.

Seems like some good battery management software would have helped.

Actually that sounds like a defective phone.
I don't see any indication that Android's battery management is to blame for that guys problem.

So from what I can see you don't have any plausible proof to support your claim regarding Android phones in general. Just some indication of a few phones with defective batteries.

Anyway here are a few lines of code from Android's source code.

Spoiler: BCL, Android Open Sorce Code

This ADC hardware is capable of sampling the sensor every 1 msec and interrupts
the BCL driver, which in turn mitigates the CPU frequency based on the currentload thresholds.

List of phandles to the cores that are to be hotplugged, when battery current limit condition is reached.

List of phandles to the cores that are to be hotplugged, when battery SOC limit condition is reached.

List of phandles to the cores that are to be frequency mitigated when BCL condition is reached.

The battery voltage threshold below which the
BCL driver starts monitoring the battery current thresholds and
mitigates the CPU on the event of high load.

The battery SOC percentage threshold below which
mitigation needs to be applied.

etc.

As you can see Android phones will throttle if its required to avoid a shut down.
Android does monitor the battery current and voltages and acts accordingly.
Also Android OS had this feature implented a few years before apple implemented something similar with the launch of the iPhone 8 and X.

There are more like this, so either there is something to what I said or throttling doesn't work on android or it's a hit or miss proposition. Either way I guess it doesn't prove anything, except android phones (and probably all phones) just shut down for indeterminate reasons.

OK, I understand you can't prove your general claim about Android phones just shutting down, which it's to be expected because it's not true at all. If you check the Battery Current Limit feature on Android's source code it's obvious that Android phones do throttle when needed and don't just shut down. There are hundreds of millions of +2 year old Android phones in users hands so I was expecting something with a little more weight like an article using documented facts to investigate the supposed general shutting down issues with Android phones, not forum posts from people having defective phones.

Aha, Apple designed batteries to have a limited life - planned obsolescence! Where are the lawyers?

I am wondering about this too. The lawyers were last seen defending independent repair shops that Apple rightfully wants to shut down. So have faith, they are not AWOL and should show up eventually.
