Does your old iPhone become slower and battery last shorter after iOS 11 update

There are reports vouching that some bench mark tests show no slow down. An open secret that some hardware manufacturers will tune their device to perform better when they detect a bench mark app is running. There are a lot of ways Apple can trick the benchmark app.

    I’m speculating Apple purposely slows down older models so that’s You upgrade.

    It is not that Apple does anything: it just creates a new faster hardware and the old models look slower in comparisons. Combine that with the fact that batteries naturally last less with time, and you have the perfect scenario for what looks like planned obsolescence, yet it is just natural aging of old hardware.

      You knew going into the update that it was the same code running on much more powerful hardware. And, you’re not forced to update by any means. So, what’s the problem?

      This is a Lie, my dad never knows anything about latest iPads. His iPad is junk after iOS 11

      This is wrong. IOS11 Makes iPhone 6 very slow. The apps start slower, slower thumb print, slower phone answering, everything.

    Do you know why Apple is the world’s best phone company? They build iPhones to last without much issues just for 2 years and then they start falling apart. They are so precise in this aspect that I believe this is the biggest engineering achievement they have yet.

      Then Samsung beats them to it again, my S7 definitely aged only after a year :(

    You guys are in tech but dont know that pushing the latest software on old hardware will cause slower performance? Lul

    I’ve seen Bluetooth turning on automatically. That drains the battery.

      In iOS 11, control center does not turn off Bluetooth or WiFi. It simply terminated existing connections. A rather stupid idea from whoever came up with that one. You have to go into settings to actually turn them off.

    It will be interesting if someone can do a direct comparison of iOS 10 and iOS 11 on the same device, without using any special benchmark software. Just try to run some commonly used apps

    so it’s not likely going to ‘drain’ the battery. i keep mine on always

    energy used for bluetooth is minuscule

    Is the upgrade forced? Android can opt out.

    Did your older PC slow down after installing a newer version of windows? Obviously I wouldn’t know if Apple purposefully does this. I seriously doubt it considering the tight performance KPIs for older Apple hardware we have to meet for app updates as part of iOS. It’s just the reality of newer software. More threads competing for attention on a smaller number of slower cores.

    iOS 11.0 was a turd on my iPhone 6S, but 11.1 runs much better.

    Iphones are built to just last for 2 years. If you dont upgrade then they may last more. But with upgrade there is no way that you will be able to get that work longer. Who will buy the newer faster hardware if the old one is not slow.
