    Im wondering does iOS12 has a better use of battery consuming than iOS9 or previews versions of iOS? And if so, is this somewhere documented with tests etc?

    It is worse than iOS 11.

    Please update your device and see for yourself then.

    If you are wrong, by updating, i will have crossed the point of no return!

    Sounds like staying with what you have is the way to go.

    If I’m wrong your battery will improve. Would you mind better battery? If I am right, you’ll regret not listening to me and suffer from worse battery as advised to you.

    #aakshey I'm on iOS9 at the moment, does iOS9 have a worse battery management than iOS11?

    I would not expect big changes in battery consumption (up or down) from a new operating system.

    The newer the OS the worse the battery will be for iPhones. For iPads it shouldn’t be very different with an iOS update.

    I updated my 6S Plus through a number of iOS betas and the final general release. Aside from speed improvements the battery usage was a little better.
    Now, on my XS Max, I’m getting 1.25 to 1.5 days of usage between charges, granted The battery is larger but so is the screen which eats a lot of power and I’m constantly;ty browsing and loading lots of pages. Either way I find photo editing to be the biggest battery eater for me. I try to do as much as I can on my 12.9" IPP which last very long.

    If you back up your phone, then upgrade to iOS 12 bit don’t like it, couldn’t you restore your phone to the previous back-up with whatever iOS you were running before the upgrade?
    I’m not sure about this. I would want someone with more knowledge to conform or deny.

    I’ve been ver happy with iOS 12 but people’s experiences seem to differ widely.

    Backups just restore data, they don't have or do anything related to the iOS version itself.

    How come it's worse for one set of devices while it stays the same for the others? They both share the same iOS, similar processor architecture and the same battery technology.
    Either you submit proofs or you stop blurting out stuff. Scaring people into the worst doesn't make you a genius.

    You're wrong either way without proof to support your statements.

    The proof is right here on this forum and on YouTube. Figure it out for yourself if you’re genuinely interested.

    There's proof to the contrary too on this exact same forum. Which one would you like me to pick?

    There isn’t. You’re wrong.

    A lot of people would disagree. There was one update that messed up the battery even when it was at 97% health. They swapped the battery for free cuz of the unusual spikes in the usage and it's been the same ever since. So yeah, I'm the one living proof among many.

    And if you still believe there's no one who's had good experience with iOS 12, I'd say you haven't read them all. You're welcome to read through thousands of posts.

    According to other results I have seen, iOS 12's battery life is about half than that of iOS 9. Maybe a little higher, but I wouldn't expect it to be anywhere near decent compared to iOS 9.

    Seems about right.

    You can't expect to get the exact same battery life with all the extra features packed in after three iterations in the OS. That'd be absolutely ridiculous. But then again, it wouldn't be like half of what you got with iOS 9. Unless, of course, you're having the same messed up battery issue like I did with iOS 12.0.1 which was resolved after a battery replacement.

    There isn't a single/general answer that will apply the same way to everyone. The reality is just that.

    On Macs, battery life is much more stable after updates. They might decrease, but not to the level iOS devices decrease. I think it's lack of optimisation for older devices by Apple. Just a guess, no proof, just speculation.
    All I say is people shouldn't update. If they do, then they should generally expect both poor performance and far worse battery life.

    Macs use entirely different OS and when you’re not constrained on space, you can manage better.
    I’d say it’s mostly cuz of the better performance and efficiency of the newer processors. They’d definitely prioritize newer devices over old ones which is pure business.

    The more complex iOS becomes, the worse battery life will be.

    We need new battery tech.

    If you want FACTS, aakshey might be perhaps not the first you should ask... have a look at what he posted about battery drain and you can judge for yourself... most people are very pleased about IOS 12, also regarding battery life....

    To get more objective information, one should only regard the same iPhone model before and after upgrading (less variable basis) ...

    so have a look here for lots of serious reports concerning battery life:
