    Will restoring my iPhone 6 make it faster?
    I've seen a lot of posts about making it faster by doing a clean install, is it true?
    And do I need to restore it while in DFU mode?

    Well it can't hurt to just update it normally and see how the performance is. Give it a few days. If you're still having issues after that, you can do a fresh reinstall though Settings> General> Reset> Erase all content and settings.

    Generally speaking though, it's not necessary. Should be fine just updating.

    I'm on iOS 10.3 right now (and had the betas).
    Performance is bad, I think an iPhone 6 can perform better.
    Tried erasing all content, no luck.
    But I heard restoring it while in DFU mode will make it faster.

    Well, if you believe you are experiencing issues and what you've tried hasn't resolved that for you, seems like it's worth trying it than (unless you are just going to go with what you already have and stick with it).

    A few points.

    First, A DFU restore may have different results than an erase all settings and content for one main reason. A DFU essentially reinstalls the OS completely. Erase all settings and content restores the device to factory state without reinstalling the OS. If you have a corrupted install of iOS on your device, an erase all settings and content will not fix the corrupted OS issue because it's not reinstalling.

    Though it is rare for iOS to corrupt, it's no different than to any other piece of software, freak bugs cause even freakier glitches.

    Second to that. If the OS is not corrupt, a simple erase all settings and content could potentially speed up the device because it is clearly out all the cached junk and removing any unnecessary files. This overtime bogs down the device which may cause performance issues.

    Lastly, it is possible a hardware issue is at play. It could be a RAM or processor issue that is causing the device to perform poorly.

    So you have already completed the erase all settings and content leaving DFU as your next step. If that fails contacting Apple to run a diagnostic may turn up something. I believe Apple charges to do it via phone or chat if you aren't under AC, but if you take it in, I believe they will do it for free.

    I find that with every "Set up as new iPhone," I roll the dice with what bugs are going to show up for me - bugs that are basically unsolveable until I do another set up as new iPhone. Stuff like App Store search tab glitching out, updates not working, Apple Music not updating, etc.

    So I find that resetting the OS may fix some bugs, but performance usually stays about the same.

    I'll try a DFU restore.

    When there is a major software update, I usually update my iPhone through iTunes as I believe it also completely installs full iOS again. Since it's an update all my settings are preserved and I don't have to backup/restore anything. It might be a good idea to do this from time to time

    Some people complain with each iOS update. 10.3 converts file system to AFS. And could have overhead or in moving files around. Also all the apps, their updates over the year(s). A "clean" base system will show if it runs okay.

    Is it possible that DFU erase might map out weak storage cells that no longer hold their data? what does iOS HFSX pre-10.3 do with read and write errors or excess attempts??

    First off it will make no difference unless there is actually a problem. When I first joined here I restored my iPhone as new for all sorts of issues from performance to battery. Never did it fix anything.

    For me the problem was always a bug that Apple eventually fixed or user error.

    However if there is some corrupt data or something then a restore could help.

    It wont hurt anything aside from time that could be spent doing something better. So if you have that, give it a shot.
