Other New battery = new phone

I see a lot of people complaining that their phones have gotten slower, and (infuriatingly) I also see a lot of people replying with things like, "my phone is fine, so stop moaning", or "it's due to the latest features of iOS, your phone is too old!", or even "just restore your device and it will get faster and the battery life will improve" (all of which are wrong in varying degrees).

My iPhone SE had been slowly getting more and more laggy, stuttery, and just generally annoying to use after two years of daily use. Animations were no longer smooth. Apps were slow to load. It took ages just to be able to take a photo. Everything was just slow and annoying, and I was cursing Apple for not making my device run better.

Then I finally hit a wall: I was on a train when my phone went dead with 29% battery power left. I tried to turn it back on, but it said it needed charging. Being out for the day, this was frustrating. Then it finally came back on saying it had 11% battery left. And stayed that way until the end of the day. Something was seriously wrong.

Thanks to the latest iOS 11, I used the "Battery Health" feature in Settings to see I was right: I knew I had 84% battery health, but now there was a new message... My phone had suffered a crash because the battery had gotten so old it couldn't supply enough power to the phone when it was doing something intensive. Huh!

At this point, the lagginess and stuttering was worse than ever. It was so bad I literally couldn't use a the keyboard without huge delays in typing.

So yesterday I took the phone back to Apple, they CS'd me a battery replacement, and now my device is like new again. Super smooth animations, no lagginess, no stuttering, no delays. Everything is fast and responsive again. Holy cow!

It turns out that iOS is frequently making huge draws on the battery in normal daily usage, and if your battery is old and can't keep up, then things begin to stutter and lag. It's not the software, it's not the processor, it's not old apps taking up space, it's the battery!

OK, you could argue that Apple could try and make iOS more energy efficient by reducing the fancier effects so the phone doesn't get laggy when the battery can't keep up, but this a huge revelation for me.

If your iPhone is about 80% health, I'd suggest getting a battery replacement. I feel like I have a new iPhone SE again: Super smooth and enjoyable to use!

:eek: Wow I had no idea 84% would be a threshold for poor health. Thank you for relating your experience with this. I have an iPhone SE that’s been more lightly used than yours and it performs well and has been handed on to a family member. It’s definitely not all down to the age/year of release. The battery draw issue is real.

After the "battery scandal," Apple gave us battery health, and labeled as a BETA app when since ages, third party apps have been giving us more information like charge cycles, a more precise, linear measurement of a battery's life, but OK you are not a left-brained geek, and I can tell you when a device "suddenly" drops its capacity say from 50% to 20% in a very short time, the battery is dying.

MacBook tells you what apps are using what % of energy, IOS doesn't have that? am not a big IOS user so I dunno, but surely there is SOMETHING like that out there to let you know to turn them off when not in use.

Ya guys, I wish everything, in these days and age were more automatic but still no.

The statistics of how much battery is used by apps has been available under battery settings in iOS for quite a while now.

I may have posted too soon. While things have definitely improved with the new battery, it still gets confused while typing things into Facebook, etc.

The phone has slowed down over time because iOS "upgrades" slowed it down and it had been intentionally throttled probably since iOS 10.2.

Whatever lag & stutter you're experiencing now is "normal" for that phone on iOS 11.

Of course you know... with a new battery, go through a couple of charge-fullydischarge cycles to "calibrate."

And I do notice, newer IOS... if you let it, it will run everything on the background waiting for (PUSH) notifications.

Is that why most aren't experiencing those type of issues?

Maybe it is that many don't pay attention to the small stuff, thus not realizing that they do have at least some performance loss/battery life decrease.

There is no way(or need) to calibrate an iphone battery.

The post I was replying to was in response to someone having noticeable issues in an app, which is different from the kind of thing you are mentioning.

While there isn't really a calibration there is typically a bit of a "break-in" period when it comes to new batteries as far as them getting to their peak (or close to it).

That’s news to me.

In the future I'm planning on replacing my 6 Plus' battery as it's at 76% in the Battery Health menu. Seeing that this actually will improve the phone makes me more excited to replace it. :)

He used etc, so that might not have been the only issue.
Yet the one that was the first and only one that was actually explicitly mentioned isn't one that's all that consistent with some sort of generic potential iOS 11 upgrade type of thing.

Everyone using iOS 11 is having some stutteryness when it comes to scrolling and animations, etc. It's just part of the OS. Whether they notice it or care about it is another matter entirely, but I can say that a new battery reduces it significantly in my experience.

Everyone? You sure?
Yes. Show me an unedited video of an iPhone using iOS 11 without any stutter for 15 minutes (moving in an out of apps, quickly scrolling up and down through menus, etc.). Not a difficult task if there's any truth to your skepticism.

It should be easy, as you're obviously implying your iPhone is one such device. Just hold it up infront of a webcam.

"everyone" is a bit over the top, don't you think?
It's a shame about your experience, but you don't need to extend that arbitrarily to "everyone". That's just not true at all.
However, you are likely safe in your corner, as it's also unlikely that someone would post a 15 minute video of their iPhone screen while using it, and also have a video that would not have video artifacts, due to the recording process, that could be interpreted as stuttering.
I guess you meant "15 seconds", which would show that kind of performance issue, even in that limited time.

Also, how would you account for those who never updated to 11, because their iPhone came with 11, and have no older system to compare?

My SE is just over a year old and is reported to have 92% of its maximum capacity. However, it's already got performance management applied because of an unexpected shutdown. I can't remember when this shutdown occurred, but I have noticed more than usual stuttering etc recently.
Do I turn off the throttling (the information page says you can't turn it back on), live with it, or go get a battery replacement? I had noted the date that the discounted battery replacement program finishes with the intention of getting a battery replacement at about 1.5 years into its life.
The other thing holding me back is that there is no Apple store in my state, and the local authorised service centre charges a fee on top of Apple's fees.

I also have seen the before and after effects of a new battery with a 6S; it's not "just iOS11". I took advantage of Apple's $30 replacement program and recommend everyone else do the same.
