It occurred to me the other day that I actually have a free battery replacement available for my iPhone due to Applecare. Interested to what what my battery capacity is at.
 
There is NO such thing as an unexpected shutdown. It is software telling the device to shutdown. The battery has twice the voltage needed to keep the CPU happy. It voltage sag is really a problem, it sounds like apple skimped on capacitors.
hey Apple, you should hire this random guy posting on this message board to be in charge of your engineers since he seems to know exactly what the issue is with your phones and batteries!

By law all lithium batteries have their own independent circuitry which does not run any software and is required to shut the battery down in certain conditions, including temperature and voltage fluctuations.

These measures are required to reduce the chance of a battery catching fire and burning down your house while you sleep.

The battery definitely can and will shut down your device with no software involved.
 
Lately, I consider their releases to the testers as alpha releases. The beta releases are when they release it as a final release to the public. At that point, the entire user base that upgrades becomes the beta testers and lots of bugs are found :(.
 
"This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power"

"Maximum Capacity: 95%"

So the battery is well into "Healthy" by Apple's standards (> 80%) but already throttling within months of brand new, still under warranty and all.

Pathetic.

What model phone?

What country are you in? That certainly isn't the law in the US and plenty of un-protected LiIon batteries are used by RC and other hobbyists - I have some for flashlights that push the limits.

I'm playing on the screenshots in the original post (the one on the right).

The point is CPU throttling starts well before the 80% threshold above which Apple considers the battery "Healthy" by their diagnostics and not in need of a change. The screenshot shows an example of this happening when battery health is at 95% (which is very new).
 
Huh, you are clearly not an engineer.
I remember we did a project when we were younger in college. Built a very crude inverter.
Had a lot of old components including a huge bank of electrolytic cans.
When we removed the DC input, (assume this is your bad battery where in effect it's actually a little more extreme than that), momentarily the output stayed where it was. This was due to the huge capacitance......
 
Thanks for the specifics...helps a lot of us..

iPhone X.

Lock screen animation bug, phone unlocks but animation goes back and forth. Looks weird.

From home when you pull down notifications, again, screen blinks.

It's hard to describe without video.
 
Talking poop + FaceID = Innovation ;)

Face ID is innovation, regardless what hatters say (hatters gonna hate)
Animoji, gimmick of course but could be fun for some. I don't care about it, never use it. There is so much more to love about iPhone X, but haters usually tend to bring up the animoji subject because they would want us to believe that it is the main feature of iPhone X.

I would more than happy if Apple just stops working on “features” and start learning about performance and quality instead, I mean at least restoring performance before iOS11 on devices that are not last gen would a decent move from this company.
 
Has any one else had the time disappear from their lockscreen? I have no idea what triggers it but it shows up after about a week or so. When it happens the widgets and camera are also unavailable from the lockscreen and it requires a reboot to fix.

Well, you’re not exactly playing because my 3 month iPhone X is already down to 97%...
 
I have a similar issue with this beta as I did in the previous two. My phone heats up (a little warm, but not hot) and the battery drains quick. Not an issue that happens every day. In the last beta it happened at most once or twice a week and so far in this beta, it's happened once. Other than that...no issues worth noting! It seems to be running very well!
 
I have an iPhone 6 that was getting throttled badly. Now it runs like brand new again! Everything is faster and more responsive. So far so good, but I'm still keeping my appointment to get the battery replaced.

I agree with you that FaceID is innovative. I happen to love my X for the seamless use of FaceID and the fast processor, I don't even miss the TouchID home button. I haven't experience any significant lag, and if I did, it's more often due to the iOS bugs. I also never use that Animoji feature but it's a generational thing, I suppose. People don't talk face to face anymore. They resort to using talking poop to express humor. My daughter found it very amusing for, like, 5 minutes and moved on from it after a while.

I can't wait for the 6.5" iPhone X Plus then I'll be good for a while.

I would have kept iOS 9.3.5 if it was still digitally signed.

These posts about who uses the oldest version of iOS are amusing but strange. Not wanting to use beta I get, but sticking to old software with security issues because you're unimpressed with the newer software just doesn't make sense.

One ominous thing with this beta. It can detect if you have an OEM battery vs a third party battery.

I replaced my iPhone 6+ battery with an iFixit battery a week or so after the slowdown issue was uncovered, but before the Apple battery program started.

The battery is still at 99-100% designed capacity, but not according to the battery info in the beta.

The new beta reports the battery as needing service and the detail window just has a spinning indicator.

The previous beta said the battery was good.
