@NewToMac2012 the only comparison I can make is that I personally haven’t noticed any differences even on low power mode. However I usually just browse take notes and play some lite games. I may have had 10.x but as soon as I got the device it had 0% battery. It was unopened and a 64GB but it may have been on the shelves for months maybe a year or two. I also was getting acclimated to the iOS experience so I haven’t had any major lags or that.

That’s about all I can think of. I know my coworkers 6 or 6S became slow after he upgraded to 11. He was on 10. Unfortunately I didn’t make a mental note of the changes and differences.
 
In the past few weeks, I’ve upgraded my perfectly serviceable 6 year-old iPhone 4S to an iPhone SE (iOS 11).

I’ve effectively moved from the ‘Stoneage’ to the 21st Century.

I couldn’t be more pleased: no issues at all.
 
Happy for you. Coming from a 5S to an SE is an incredible difference so I can only imagine what it’s like coming from a 4S. You’d have loved it even more if you were on iOS 10.3.3 though (performance-wise). The battery was impossible to kill and aops and animations were just a little bit better. Probably has to do with many little changes such as the longer animations between opening and closing apps, as I believe it’s more CPU intensive now, and also the translucent control panel - which doubled in size and is now way more transparent, which is harder on the CPU and battery too. Not noticeable unless you’re on your phone all day long I guess, though. Ah well
 
Graphic-intense animations. They made iOS 11 have a “fancier” animation than iOS 10 and you don’t really notice it until you switch and then after a day or two you completely forget what they were like on iOS 10. But since that is where the lag and frequent stuttering on an SE can come from, I can only imagine that that is where a significant drain on the battery comes from. What other new features were added to 11 that could make such a difference?
Doubtful that a few differences in some animations really play much of a role in something like battery usage, let alone a significant role.

I dunno. Depends on the frame rate of the animation.

If that’s the case, why did Apple restrict the transparency (when it first debuted throughout iOS) to the newer models, citing that the iPhone 4 (or was it the 4S?) could not handle them adequately and that to improve performance they would only have opaque menus and options. Even the address bar in Safari and stuff never went translucent on the older models.

I don’t know, I’m not an expert, all I know is that whenever I *do* see any lag or stuttering on my devices (all SE’s) it is ONLY when opening or closing an app and it is always during the animation. And these are simple apps, like Safari or Notes, or Calendar etc

The animations affect the performance/speed of the user interface, but have a negligible affect on battery. Look in the battery section and you'll see that the screen and perhaps a few apps are consuming the battery. Nothing happens long enough in a transition animation to have much battery drawdown. The reason some of the animations were restricted from some older devices was all about the user experience, not battery. No one wants to watch very laggy transition animations, and the older devices lack the horsepower to do some of the modern ones quickly.
 
I bought an 64GB SE about 2 weeks before the last refresh/capacity upgrades (Spring 2017)
It is still on 10.3.3
Have been too chicken to upgrade only because I fear the battery will drain a lot faster if I upgrade to IOS 11.
As a light user, the battery easily lasts a day to a day and a half.
Of course the Spectre and Meltdown issue all over the news makes me think Of upgrading like I should.
Has anyone had a big jump in battery lasting a lot less with this SE?

P.S. My iPadAir is on 11.2 and battery drains faster now, but it is a few years old too.....probably older battery issues.

My SE is on 11.1.2. If the battery is lasting less long than it was on 10.3.3, I haven't noticed it. Safari scrolling is MUCH nicer, though.

Do not leave iOS 10. You won’t get even one day of usage on iOS 11. I used to get two full days, now I can’t make it one.
 
The battery drain is exactly why I have not upgraded to IOS 11 yet. I have heard the warnings from a few iPhone 6 and up users, and keep pressing “remind me later” to update - it almost got by me a few times.
It’s a shame Apple can’t have the next IOS update improve these problems. The SE has been a great little phone so far since buying it!

Don’t let it get you!

Settings > General > iPhone Storage & locate the iOS update and delete it from your device. Frees up space and stops the update from installing if you miss the window of opportunity to dismiss it.

Been there...
 
This was my experience with 11. I downgraded to 10.3.3. Much smoother, better battery life etc.
How do you downgrade the ios?
[doublepost=1515330121][/doublepost]I would like to have my phone back to before ios11. How did you do it?

After the 11 update, the phone suddenly had multiple performance issues:
- freezes while editing when the red bubble comes up
- touch ID can’t be restored
- phone crashes a lot
- phone shuts off suddenly (though bettery is in 30+%range)
- zoom freezes (only half of screen would zoom)
- delay while typing in multiple apps
- slow loading up apps
- few apps don’t work at all

I have a 128gb phone with 60 ram free, 6 plus phone. I already reset phone settings. The zoom issue was fixed after reset. All other issues remain.
 
It’s been great in every metric, I just have some annoying bugs, especially the one where the icons get closer to the bottom like when you set up a hotspot, it happens like half of the time I go to the home screen, does anybody else have that? I’ve had it since the first iOS 11 beta and they still haven’t fixed it.

I downgraded when iOS 10 was still being signed, unfortunately its not doable anymore.

I think you do need to restore your iPhone as what you have described sounds beyond the normal iOS 11 issues!

And ten install tvOS profile...
 
I installed (clean restore and restore from backup) iOS 11.2.2 because of Spectre and meltdown and I must say battery life dropped just about 50%.
It’s the worst system version I ever had installed :/

Wish I had seen this earlier. Figured I had nothing else to lose and updated one to the latest version lol. Darn

Not having this issue at all on my iPhone X. If I did I would lose my mind.
 
Both our 32gb SEs are working perfectly on the latest IOS 11 version. As smooth as ever.

I don't know what most of the other contributors to this thread are complaining about.

Battery life is excellent with both phones having about 50% left at the end of the day but this usage is highly dependant on personal utilisation of the phone.

There must be thousands of people out there who are quite happy with their phones and don't feel the need to agonise on here about "faults" that are barely noticeable to the rest of us.

Tha range of "faults" reported after each upgrade are all depressingly similar and yet life goes on and the phones continue to provide the same service they have always done for the vast majority.

To most people their phones are not a hobby but a tool to facilitate their lives. Long may it remain so.

I disagree. It’s a problem for me because I use my iPhone se as a navigation tool during my day long mtb rides in wilderness. Still investigating the standby times in low battery mode, maybe i’ve Found the culprit, but I need to do more testing.

I don’t consider jitter in animations as simple as unlocking the phone or swiping to the widgets screen smooth.
