It's normal that your battery health drops

Apple, break the laws of physics!

Even the newest watches have 18 hour battery life, so of course one that is almost a decade old would be the same or worse. It's actually amazing that it still lasts a whole day after all this time.

Some more than others. iPhone 7, for example, had some issues with the earpiece and other hardware things. You see much less iPhone 7's out there than 6s's. The model is a factor. 6s is known to be one of the best, most resilient iPhones ever made.

I switched to LTE from 5G Auto and didn't see any difference in my battery life so I just put it on 5G Auto again. I think it actually rarely connects to 5G in this mode anyway because 4G speeds are plenty. Getting about 800Mbps.

Ethically and legally a grey area, but yes - go ahead. It'll work.

It wouldn't reduce the price. Mass production keeps the price low. Customization, even if it's lesser components, would drive the price up.

I’d wait if your watch still works. Gonna be a redesign which hasn’t happened since the series 4. (Unless you consider 1mm extra screen in series 7 a redesign)

Not since the App Library was introduced.

No we have it in the dock because we never use it

They need to rethink Springboard from the ground up at this point. The only real improvement to it since iPhone OS 1.0 is spotlight and widgets.

Invest 80$ in a new battery (at the Apple Store and yes - it’s worth paying the money to do it from Apple directly)
