Okay i see, from what you and everyone else here says, I'm not going to trust a YouTube video. I'm just still considering updating. Well, I'm neutral about the new features that ios 18 brings. My main concerns are battery life and overall system performance. I don't mind about features and security. Of course tho I'll update if battery life and system performance don't get negatively impacted. Though it's normal and logical that performance and battery life will be negatively impacted since there will be new features and more stuff than the older ios versions so they will drain more battery and system performance right?
You can do a search for every single iOS version, and you'll find that people complain about it decreasing their battery life. So, either Apple is completely incompetent or... people are mistaken. Given that most people don't report such problems, I'm going with the latter.
You will see greater battery use right after a major update, usually for about 24-48 hours, while the phone finishes up all the background housekeeping tasks. It's also possible that your maximum battery capacity will change as the iOS updates also re-calibrate that estimate (and that's all it is, an estimate).
There have been a few rare instances where an update caused unexpected battery drain in specific hardware. Apple usually fixes that within days. I've seen no such reports for iOS 18.4.
