My SE old battery lasted longer on iOS 10 than the newly replaced battery on iOS 12.
You should realize that iOS 12 is loaded with more features than iOS 10 which requires more processing power. Providing the iOS with more battery capacity doesn't reduce the power requirements. So, I wouldn't call it Planned Obsolescence in your case.

Why do these posts keep coming up? So I have the XS and I update it to iOS 13 as soon as it comes out. This happens. You will tell me to buy the new version? This is either ironic, or blatant trolling. You cannot be serious.
Obviously, you will not be able to explain why my 6s has great battery on iOS 9, why my 7+ is getting 12 hours on iOS 10, or why my iPad Pro 9.7 is getting 14 hours on iOS 9. Not new hardware, no iOS updates, perfect battery life.
These posts are already vexing when people are on older devices, because they're misguided, but this one is on another league.
[doublepost=1545219521][/doublepost]As usual, iOS updates decrease battery life. iOS 12 is no exception, unfortunately.
Yeah and new iOS updates mean more functionality that newer processors are able to perform more effectively than older processors. Also, partly because they focus most of the optimization for the newer devices compared to older devices.
If you run iOS 6 on an iPhone 7 or X I'm sure it'd last days as those versions don't involve as much functionality.
This itself doesn't prove any malicious intent from Apple.
