Is IOS 18.6.2 still safe on the 12, or should I upgrade to the 27?
I haven't updated my iphone 12 since ios 18.6.2 because the battery health was rapidly worsening—and funnily enough, it stabilized at 69-70% health and has been the same for a year now. Will updating to ios 27 nuke my battery? I really don't want to have to get a new phone anytime soon, and since I stopped updating, I swear all of the problems (quick battery drain, overheating) stabilized. How unsafe is 18.6.2 security wise?
