Exactly my experience on the 12 Pro. According to “Battery” in Settings, the worst offender is Safari. I’m not use any social media app and have Background Refresh disabled (since ever). My iPhone is hot just by browsing this web. All other apps are closed.
Yeah if your 12 is draining battery fast, this makes me think it's an unintended bug in iOS. There is no way apple would intentionally throttle the latest current model they are still selling as their flagship. Hopefully 14.7 fixes the issue though.
 
iPhone SE 1 running iOS 14.6. No complaints here.
iPhone SE 1 running iOS 14.6. Battery drain from July 2020 with iOS 13 (3 weeks of Apple Support calls for hours, chats and mails, problem not solved), update to iOS 14 in October 2020 and in two weeks it needs battery replacement (from Apple); 3 months and battery was at 95%, other battery replacement in warranty and now, again, battery drain 100-0% in 3 hours. This is my seventh iPhone SE from day one, everyone changed in warranty, adds two screen replacement in warranty (everyone with the same issue, Home Button fails in 3 weeks). I'm an Apple user from Quadra, 1995 I believe, never seen a poor quality products like the last 5 years (changed 5 screen in my first MacBook 12" 2015, everyone in warranty or free extra warranty, in 4 years, it needs a new one but I give up and buy a new one MacBook in January 2020; AirPods 2 fails every calls; Apple Watch 4 gold aluminum scratch himself alone; 2° MacBook 12" 2019 new gold changed 2 screen in warranty and 1 top case because the Genius scratch it while change the screen; every type of issues in MacOS, iOS, CarPlay, HomeKit sw: I think Apple Genius have seen me in the last 5 years more than my wife!) from Apple.

Same here. One weeks ago I need to put it in my freezer!!! One year of these "Apple experience" and I've stopped every purchase from Apple over 120€ (just HomePod mini and AirTags for old parents). I need a new iPhone/MacBook/Watch but I'm not sure of that, I can't trash my money with that 💩 and lost my time with unbelievable "Genius" or Apple Support employees who don't know the products they sell.

Well, they're going to find iOS 15 interesting. Public beta 2 on my iPhone XR is running like an absolute dog. Choppy, slow, and abysmal battery life. Not too many UI glitches or app crashes (apart from my banking app... annoying) but wow, it feels like using my iPad 4 on iOS 10 or my 3GS on iOS 6. I know, early days, but it's the roughest public beta I've seen in years.
 
Anecdotal for sure but I'd noticed in the past few weeks my XS has gone from reliably getting me through the day to needing to charge at ~2pm. Also noticing UI juddering which smells of CPU throttling - despite my battery health being 84% apparently.

May just be a sudden very rapid battery degradation, certainly can't complain after 3 years of solid service, but disappointing to see such a sudden change. Roll on iPhone 13 I guess.
 
Keep doing this and they’ll stop supporting older products. Insane that the iPhone 6S is still being supported. Don’t ruin this.
Yep, I tried iOS 15 beta 1 on mine, browsed the OS for an hour and... couldn't notice any slowdown.

Competitors are far, FAR from doing that.

Every iteration of IOS and MACOS is slower than the previous version on the same device.
Since somewhere around iPhone 5S / iPhone 6, it's simply not true anymore.

My iPhone 6S has no slowdown whatsoever on even a BETA of iOS 15. And betas never run as smooth as the final release.
 
I don't recall signing up to anything that guaranteed a particular level of performance when I bought my iPhone.

On the other hand, I absolutely do expect my phone to get a little slower over time. Your phone and mine is under attack all the time by miscreants on the internet. Your phone and mine gets updated quite often to counter these attacks. It takes CPU and battery power to do this.

After an upgrade, I fully expect my phone to spend quite some time doing background processing and re-indexing.

I bought my iPhone years ago, and it is still going strong. No complaints here.

And if I'm bothered about how apps are behaving, Apple have thoughtfully provided a means to examine which apps are consuming the most power.
 
Check your energy use in settings and what has background access. Sometimes some apps are working in background and you don’t even know why or what they are doing. I’m guessing, but seems like they get defaulted to on sometimes during app or iOS updates. I keep mine mostly off, I would be wary about spyware like Facebook, etc
No, this isn’t caused by background activity. At least, no operation that’s user visible in Battery. Every operation seems to take twice the battery at it used to, and background activity is just about zero. Either a whole bunch of batteries just went bad (which is totally possible) or the iOS is using much more battery than it used to. Based on the heat, I think it’s the latter: There are background processes as part of the OS that are now working much harder than they used to, draining battery and generating heat. That needs fixing.

that iOS version slowed your phone without your permission to preserve battery health and components to get damaged.
No, this isn’t why. Battery health is cooked. Components aren’t going to get damaged.

Your phone is slowed down when the battery is in bad shape so it won’t crash continuously. That’s because when it’s crashing continuously, it’s useless, and this is a phone and it has to work. (Although sure, that continuous rebooting probably damages the battery even more… but only because it's being worked harder pointlessly rebooting over and over.)

That’s it, that’s all.

Exactly this.
In July 2020 iOS 13 in my iPhone SE 1 had 14 hours background processes of Safari in night, while I’m not using it, then in Music, while I’m not using it (I’m an iTunes Match user, but there wasn’t an activity from that), then in iCloud, then in Mail. I canceled every app not strictly useful, set the iPhone as a new one, spent hours in stupid excuse from uninformed employees called “Genius”, but the problem was the servers calls from iOS to Apple.
And this continues today, one year later (for me; others are in the same situation by years, check Apple Communities in Apple site).
So it’s time to spent some billions in QA for Apple or refunds buyers, if possible.

Yes but… that iOS version slowed your phone without your permission to preserve battery health and components to get damaged. That’s ok, if they had 1. informed users 2. Give the option not to slow down the device, what they made after the scandal, BTW.
Well it didn’t slow down every device. It only slowed them when the battery was in the process of spiking. They did inform everyone in the update notes, just not explicitly or advertise it.
 
iPhone 8 user here with such issue.

The phone becomes terribly slow to use up to the point it can’t take any pictures using the built in camera (pressing the shutter button froze everything). The issue surfaces regardless of battery charge levels, it does this even when with over 90% charged.

On the bright side, rebooting the phone restores its full speed (full shut down and then start up again). Until ~3 days when the issue re-surfaces.

Storage is not an issue; I’ve got 256GB with only half full.
 
Wait, is this true? The throttle gate was real and plenty of reports. But MR didn't even say anything about 14.6, and I have not seen any complaints from the tech tubers. What are they talking about?

They have many media sources and a gaggle of lawyers with a fluffy named "Consumer Protection".

Consumers simply can't see past tomorrow and they get hurt by it. Lawyers are scouring anything in ToS, media etc looking for anything that can be litigated. It's why we see warnings not to eat your power cable or do not put your smartphone in a microwave oven. Small group of lawyers win big, a handful of consumers get a bag of peanut shells, and companies lower quality or charge more to cover costs on what amounts to 80% nonsense, along with companies avoiding any quality upgrade that looks like it could be litiigation bonanza.

America is oddly huge on this litigation business. I say oddly because we also have an outlying proportion of tech success.

Amazing. My cracked 7 Plus purchased in 2017 lags sometimes, to be expected given its age and consistent use. Previously my LG G2 grind to a halt, I couldn't even make a call.. This 7 plus is the longest I've held onto a phone and I'm pretty happy its been such a low maintenance and reliable device to make calls, texts, and access internet. The level of nit-picking is pure greed here because I can't imagine the devices listed above being anymore hampered than the one I've been abusing over the years.

Just my 2 cents.
 
My iPhone 4S was so slow using iOS 9 that I reverted to iOS 6 and updated to iOS 8. Yes they are still signing those.
 
Software will sometimes have bugs in it. 🤷🏻‍♂️ Complex software definitely will.

Apple isn’t supporting older devices to push users to upgrade. If anything, Android users with older devices are pushed to upgrade if they still want to receive updates.
