Understood.. but if these batteries are known to be deficient then why push the envelope with faster CPU/GPU year after year? Something's gotta give here.
Are you suggesting they not improve the CPU/GPU?
Again, beleive what you want. iOS is eleven years old and is built off of OSX. Plenty mature. Excuses are just excuses.
Apple users are trained to think that new software = more complicated / more demanding to run. This isn’t the case for the rest of the computing industry, but it’s an almost certainly on Apple designed devices after three years of usage.
It’s based on it, but iOS is not as mature of an OS as OS X or Windows on any level. What makes you think it is? How is it? Look at the API, the sheer amount of changes in iOS compared to desktop OS.
