Yeah, my 6s Plus has the worst battery of any Apple product I owned. Constant shutdowns at the slightest hint of cold, battery meter in free fall to 1% and then it runs for 6 hours in that state. Capacity estimate says 80%, but I call BS, it’s more like 8%.
Fortunately my Xs is on the other end of the spectrum. It was at 100% for over a year. After 21 months and 267 cycles it’s at 95% capacity.
What other iOS device than the 6s/6s Plus had the mega-drain thing where you can watch the percentage plummet from 100% to 1% or so in a matter of 15 minutes even though it has hours of juice left? It did this crap when it was new, so blaming new OS versions doesn’t cut it. This is no ancient legacy device, we’re talking about an iOS 14 compatible iPhone here.

There’s a bit more going on with the 6s than can be explained by ”hey, it’s old”. I’ve had a total of 10 iPhones and iPads since 2008, and the 6s (Plus) sticks out like a sore thumb in the battery department. Much worse than anything that came before it. My 2010 iPhone 4 was just retired after sitting for 7 years in a 30-pin dock with the screen always on, showing the weather. It’s at 680 cycles and in better shape battery wise than my 2016 6s Plus.Unfortunately the iPhone 6S hardware is doomed to poor battery life on modern versions of iOS due to its hardware. It wasn't until the iPhone 7 that the CPU had cores specifically dedicated for low power use for background functionality and other task.
...
People like to assume there is a conspiracy but its just how hardware and software evolves....you get new features which negatively effect the battery OR you don't get new features which negatively effects the user experience.
