iOS 12 on iPhone SE: is performance/battery life worse?

I just installed iOS 12, seems very very nice so far. Very smooth, noticeably more responsive than iOS 11! I really like the shortcuts app too.

It’s so strange- the hardware should obviously be the same barring slight differences in phones, but I guess differences in settings and installed apps, etc. are the main contributing factors.

Well, I've thought that maybe those differences have something to do with the A9 processor (16nm TSMC vs 14nm Samsung). I have the TSMC chip and I always had great battery life, whereas some people I've known, maybe with Samsung SoCs, barely had 3-4 hours of usage. Maybe it is a factor.

Good, I hope you don't have any issues and enjoy your iPhone. You could see how long your phone lasts now, on the Battery preferences pane, the screen time.

Oh, and by the way, I've seen voice memos app, while recording, is just accesible on the lock screen. On the SE, does it show that same behaviour? Is there a way to have it the way it was previously (not interactive lock screen)?

I'm not seeing a way to disable the interactivity on the lock screen for voice memos... There's got to be a workaround somehow though, it could be quite a security problem if anyone can stop your recording.

Interesting - you may be right. My chip’s
Model number is N69AP which I assume is Samsung, which would explain the battery issues then. I had no idea this chip difference was a “thing”. Even so, I was getting good battery life on iOS 11, now I see a percentage drop every 3-5 minutes at least.

UPDATE: After researching more, apparently it is in fact a TSMC model.

significant drop in battery life compared to 10.3.3. I skipped iOS 11 but after reading so many positive reviews on iOS12, I thought the story would have been different.

screw this!

I suggest you to calibrate the battery.

Thanks but I did that as soon as I installed 12 and had issues. Made no difference.

Update: Battery life is still definitely worse, even with low power mode on all the time. Last night my phone was in airplane mode and dropped from 97% to 94%. I can't recall that ever happening. Still, it's not terrible....I can sometimes still go two days...just barely

If I make a rough average of what people are saying, it seems like the iPhone SE is noticeably more responsive on iOS 12, but it has noticeably worse battery life.

A hard choice to make! I'm very happy with both performance and battery life on iOS 11 on my SE. I feel like I would be stupid if I ruined that balance by upgrading. But if performance would be even better, without any degradation in battery life, I would be willing to upgrade. But it's hard to know what it will be like, as lots of people are experiencing different things.

My iPhone SE is a bit less than a year old, and battery health says it's 96% of its original capacity. But this was still on 100% just a few weeks ago.
Usually when I put it to charge at night, the battery is at around 60% charge level during a day of light use (a few iMessages, a phone call, checking the calendar a few times, and not much else), or at 40% during a day of heavy use (which usually means a few hours of GPS navigation, a few short phone calls, lots of messages, taking a few photos, etc). It's hardly ever less than that. I've never need to use a power bank during this entire year. I've really gotten used to how I don't have to think about the battery, I'd be sad if this were to change.

I was on 10 when I jumped to 12 and I'd go back if I could. Never found the SE to be slow on 10 and I really liked the peace of mind knowing that I would never run out of battery...sometimes I went 2-3 days between charges.

It's not a hard choice to make. DON"T UPDATE!

You hear it from a regretted iPhone SE 10.3.3 user.

I noticed after a full charge this morning that my SE dropped 11% in just an hour of no use after taking it off the charger. Received a couple of texts, but that’s it.

I’m planning to get the battery replaced before the end of the year, so that may help, as well as an update to the first bug fix. It runs so much faster I can’t bear to go back ...
 
Mines an OG TSMC 64GB model bought on release day - It has had every single iOS 11 and iOS 12 Beta on it, currently is running 12.1 Beta

It easily lasts 2 days after a full charge, always has, and that's with normal use

Weird.

I am speaking from my own experience. There is nothing wrong with 10.3.3, no need to take the risk with iOS 12.

Well, that's what I was saying, there's your experience and there are those of others which can and seemingly do differ, so it seems that it's not just that simple.

Thank you @pkts , maybe I shouldn't base my actions on what a single person says on the Internet, but if what you're saying is truth (I don't say it's not), I should stay on iOS 10 forever -on my iPhone SE-.

It's sad. I truly wanted to update, but battery life is too important for me.

[doublepost=1537959758][/doublepost]There is an article at Forbes online that tells you how to fix the battery issue if you're having it. Lookup "The One Thing You Have To Do Fix Battery Life In iOS 12". It is written by Anthony Karcz /Consumer Tech.

Good old Forbes with its usual clickbait generic articles that get just get repeated for pretty much every iOS update.

No, that's not what you said. But thanks for discounting my experience though.

You were suggesting people to take chances "it's okay to update because it 'might' work out well for you'.

I was saying "if you are happy with 10.3.3, don't update. Because iOS12 'might not' work for you. It certainly hasn't worked for me"

Actually what I said is in fact what I said originally (without any suggestions or discounting of anything one way or another):

You, on the other hand, in fact, said something somewhat different originally:

No, not really. I used an iPhone 4S until last year, running iOS 7. I refused to update iOS because it would have made it slower. It was a great phone and never had any issues with it whatsoever. Sometimes I still use it today and even being used to my new iPhone, I still find the 4S super pleasant to use. Some would say it's a huge security risk, but what exactly could happen? There wasn't anything that sensitive on that phone. If hackers want to steal my photos of IKEA furniture, or my friends' phone numbers, or read my emails in a language they don't even understand, go for it, they'll just be wasting their own time.

I'd rather have a phone that works well, and that I can use, than a phone that is deemed "secure" but that doesn't work and that I can't use for its sole purpose: to quickly get stuff done and then put it back in my pocket. Then again, any iOS version can have huge security flaws, not just the older ones. How many times per week do you read that a new software update brought a security flaw that wasn't there before? Just look at yesterday's Mojave update. It has a new security hole that wasn't there in High Sierra.

Past experiences have taught me that the most common, most likely way I can lose hours of my life is by installing an update that causes all sorts of problems and slowdowns. Not security issues. It's almost a daily occurrence in my life to help people who accidentally installed some update that messed their system up. If I could get paid for this, I would be making a lot of money. This is a much bigger and more common problem than viruses or security breaches, and it wastes much more of people's lives, since pretty much everyone is affected.

There's this obsession with "being secure" but people don't even know what that means. It's just another meaningless term like "sustainable" and "green" that sounds great but doesn't take into account a bunch of other factors.

All in all, if my phone is slow, sluggish, and drains the battery before the day's over, I'm simply not going to use that phone. So at that point, I won't be benefitting from its "secureness".

Totally agree!! I am still using ios10.2 on my SE, I concern about the performance than the security risk , hacker waste their time to hack my phone if they want to !

Asked my partner what they thought of iOS 12 on their SE. Not noticed a difference.
 
Didn't note anything abnormal. On the other hand, I've always kept most gimmicks (transparencies and movements) disabled.
