This always makes me wonder. If we accept the current thought that Apple forces obsolescence then it would seem to me that the answer is simply not to upgrade.
Yet the other side of the coin screams security.
Why do those who believe in forced obsolescence upgrade? Is the threat of decreased security that strong?
Those who upgrade at every opportunity seem to be quiet on the issue of forced obsolescence.
It's just interesting to observe.
Currently still sitting on iOS 9.0.2.
Even if I werent a jailbreaker, I'd still be paranoid about updates screwing over my phone's performance or battery or both. I've experienced it too many times. The reality is 'security' is an excuse to update -- there are plenty of 0days and backdoors in iOS that Apple hasn't patched, or they've probably stayed quiet about knowingly for gov agencies, etc. (speculative, but thats my impression given they dont seem transparent about anything anymore really)
Even going to 12.1(.0) from 12.0.1 on XR, I noticed a lot buggier experience in general. Not so bad as some previous versions but a drop off. Got a replacement phone for reasons unrelated to that, and it came with 12.0.1 and its staying on that.
Could leap to 12.1.1 while its still being signed (which should be exploited once a new JB comes out through 12.1.2), but dont really want to take the risk of degraded experience. Same with my watch thats sat on 5.0.1, could easily be updated to 5.1.3 or whatever and pair (even without EKG functionality) but battery and performance are great.
Could leap to iOS 12 with blobs once theres a jailbreak for my 12.9 2017 but I dont think I'll bother because my ipad is performing perfect and getting great battery
My homePod I refuse to update from 11.2.5 because the sound signature changed 11.3 onward
I have an external SSD with mojave on it to tinker with, but my main OS on the internal drive of my 2016 nTB MBP remains Sierra 10.12.6. high sierra was nonsense.
I do
not trust Apple updates in general
