What makes you think that Android isn't subject to the same physical limits of older batteries? You have more ability to customize the Android phones response to the battery condition but that doesn't change the underlying reason for the slow down: The battery can't handle the requested load anymore.

The battery can't handle 1 year of use because they undersized it. A 1 715 mAh battery will, once aging, be less able to provide the voltage asked by peak CPU usage than a 2900 mAh battery that has aged for about the same amount of charge cycles.

iPhones are the only device sold by Apple that are only rated for 500 charge cycles before degradation starts. Macbook, iPads and Apple Watches are rated for 1000 cycles. In the case of the Apple Watch I'd guess it's because despite being tiny, the SOC also doesn't ask for as much peak voltage as the phone SOC.

I've had the Honor 8 for a year. It's still holding a great amount of charge and running fine and as fast as the day I bought it. And unlike my 5s, no phone update is coming to turn it into a slow crawl.

The iPhone battery problem with regards to the topic, spontaneous shutdown at 30% and less battery remaining, is probably exacerbated since the evolutions that made those SOC more powerful than before. There wasn't a large wave of 5s owners having spontaneous shutdown requiring an OS update to throttle the CPU. That only started with the iPhone 6. A combination of paltry battery and modern SOCs having peak power usage that stress such battery more than before.

That's one way to celebrate being an Android user.
