No matter what Apple says: battery life on my iPhone plummeted after I installed iOS 11. Speed went down a bit, but that was you be expected. Hoping 11.1 will address the battery issue. As far as I know, a factory reset won't downgrade you to a previous version and it's nearly impossible to do so. Obviously yes, you don't need the fanciest, latest iPhone in most cases. Mine is a 5s, and I may upgrade to SE eventually. Edit: typo

I have both Oneplus 3 and iPhone 8 of recent, the OP3 have more than double the battery time so I'm really hoping that it is a system issue.

I had a similar problem after installing iOS 11 on my iPhone (7 Plus). The battery life was so bad, I was having to charge multiple times per day. I installed the public beta of 11.1 out of frustration, and I'm pleased to say it's fixed the problem. At this point I feel like the battery life is back to "normal" (iOS 10 levels).

  Glad to hear that, i hope it get released publicly soon.

  I also own an iPhone 7 Plus and iOS 11 had no discernible impact on my battery life. I'm consistently between 30% and 50% at the end of the day depending how much I use it.

iOS11 has been bad enough that I've moved over to a Galaxy S8. The difference in stability and smoothness is night-and-day.

  For a counterpoint, iOS 11 has been completely smooth sailing for me, absolutely no problems or performance impact. I know at least a dozen people with iPhones (of various generations) and none of them had a bad thing to say about the update.

iOS 11 has been such a disaster for my iPhone 7 that I'm moving away from Apple altogether. The phone is full of UI glitches, unreliable, has horrible battery life, Bluetooth connections fail constantly, and it's so generally slow it can't even reliably play a pre-downloaded podcast while opening an app without it stuttering badly. They've put out some bad software updates in the past, but this one is pretty inexcusable especially when you consider it took away as many useful features from the iPhone (3D Touch app switching, Notification Centre from Reachability) as it added.

  Yep, same here. It's a dumpster fire. I just ordered a Pixel 2 XL. Fingers crossed...

    Make sure not to turn it on until december with the first Oreo update: Google will be supplying software updates recalibrating the screen and 'fixing' the burn-in, reports say. https://arstechnica.com/gadgets/2017/10/google-addresses-pixel-2-display-and-audio-complaints-ups-warranty-to-two-years/ https://arstechnica.com/gadgets/2017/10/google-addresses-pix...

    Same here. I've got Apple phones, iPads, MacBook and iMac. Have had Apple phones since the 3G. This update is the final straw, my phone has gone from good to unusable. Siri takes so long to process commands now that I've stopped using it. Everything is so slooow. I just preordered a Pixel 2 XL as well.

      I usually quite like Google's flagships, but I can't justify the price any more. My Nexus 6P's battery only lasts two hours nowadays, as it dies at 40 or 50%. I don't want a phone that costs a small fortune and barely lasts two years, especially one that doesn't have a headphone jack. Immediate updates are nice, but the downsides are too big. I'm looking for another phone model I can switch to, maybe the LG V30 or some Xiaomi phone.

I wonder if the performance and battery issues that some people have been having and others have not can be explained in part by different chipsets and/or modems and iOS having to deal with both: https://www.repeaterstore.com/blogs/main/for-better-cell-signal-buy-the-a1865-m https://www.repeaterstore.com/blogs/main/for-better-cell-sig... That article mentions that the iPhone 7 was the first one to have both Intel (non-CDMA) and Qualcomm (CDMA) versions.

  quite possible. I also noticed my battery usage is way higher in some countries than in others...

I was also convinced that iOS 11 caused my battery life to plummet. But it turned out my battery was just broken. You‘d think that batteries should last longer than a year, but it‘s a question of statistics: Some batteries last longer, some deteriorate quickly. I was unlucky with my battery. Tips: 1. Check your battery health. Coconut Battery lets you check your battery health. If it is under 80%, consider swapping it. 2. 3rd party repair shops are faster and a lot cheaper than Apple.
