iOS 11.3 Beta 2 Introduces New 'Battery Health' Feature

RealAppleFan said:
So hardcore Apple defenders (in other words not true fans), please let us know right now why this wasn't always a feature?

I'm waiting.....

The option to turn the power management off (until the next unexpected shutdown occurs)? Because it should not be there. It's just a concession to the rage of stupid customers fueled by undue coverage. I'm glad they didn't add an actual iOS-style toggle for this but rather hid it in the info text.

The added information (about battery health and whether performance management is in place)? More information is always great, as long as it's not shoved into your face. Who said it shouldn't always have been a feature?

Well this is fun.
iOS 11.3 Beta 2 bricked my iPad Mini 2.
Won't charge, turn on, reboot, or enter DFU. Just dead cold. Could be a coincidence as the battery health wasn't great but it had plenty of power when I updated.
I may end up doing an out of warranty repair/replacement on it.

This is intended as a failsafe to keep the device from going into a perpetual shutdown reboot loop because the power might spike during startup.
Therefore a shutdown kicks the feature back on so you can boot it back up.

So why does it stay on after boot up?
2017 and 2018 forgot that internet posts are not necessarily correct and are just one's opinion which may or may not be uninformed.

To keep the phone from shutting back off. It's very likely that you won't have the opportunity to go into the battery screen to turn the feature back on before it shuts down again leaving you with a phone that you can't get to stay in long enough to do anything with.

If the OS turns the feature off after booting up completed as you ask, it may immediately shut down when the feature is turned off.

It's a failsafe.

So in practice the ‘disable’ button is meaningless
 
Not sure if this was asked earlier in the thread, but will the new update tell you the cycle count of the battery?
 
Will be nice to see how my battery is holding up. Fast run downs and fast charge ups make me think it's not 100% so this will be good to keep track of.

If you get lirium for iOS you can see the battery health. iOS apps aren't super accurate but they are pretty close.
I also use one called "battery health - your doctor" by Yaroslav Snisar which has a widget that you can obsess over
There are more but those are two hepful ones for battery health.
CPU Dasher X is another good ap.
If you have a mac, get coconut battery.

Why do people have such unrealistic expectations? You buy a phone knowing (or should know, not anyone else's fault if you don't) what happens to batteries. They get older, they wear out... that's what happens! Then the one company that actually attempts to mitigate these problems by putting a crash-prevention feature into the phone are now the ones having to pay for a problem affecting the whole industry. People who never in a million years would have noticed a difference in speed and power in their phone - other than it naturally slowing down through running older hardware with new software - are now complaining that they've been royally screwed! You haven't been!

That's not how it works at all.
If you go from 100% to 5% and recharge, that is one cycle.
If you go from 100% to 50% and recharge, that is a half a cycle. You would have to go from 100% to 50% and recharge to 100% twice to get one cycle.

I know a cycle is 100% worth of recharge, but depth of discharge plays a huge role.

I had commented this previously as a guess, but it looks like throttling will NOT be in place on the iPhone X due to it having a battery capacity more in line with what every other manufacturer in the world uses.

The iPhone 8 had 60% the battery capacity of the Samsung S8. The iPhone X has 90% of the capacity of the S8. That means that as the battery dies like Apple say is going to happen, the capacity will more than likely still be higher than that of the iPhone 8 when new. It will still be able to cope with these voltage spikes as it deteriorates that should have been handled by the earlier phones in the first place had they put in a battery with sufficient capacity.

Now this is an interesting train of thought. :)

haha,Apple explanation in battery option is ridiculous. "Good day lad,your phone experienced shutdown. We at Apple care about you,so we just want to inform you that your battery is screwed and this is absolutely normal.We just didn't want to tell you because you would worry to much. Now you know and you will worry. Now you can disable our new most famous option in battery management to enable unexpected shutdowns,because we care".Problem solved,give us 30$.

I can see one reason where this makes sense:

You're standing by the side of the road, your car has had a mechanical problem and you need help. Your battery is weak and you haven't had the time to get your battery replaced because the genius bar wait is long and the batteries are all backordered anyway:

And then things get worse: Stanley the crazy murderer is standing near your car with a big knife and he's making stabbing motions at you. But, your phone just shut down because you wanted full speed on your phone and the weak battery just died. You need to make a 911 call to have the police take care of Stanley before he stabs you and also to get a tow truck.

You fire up your phone and because it defaults to throttle-mode you were able to make the 911 call to stop Stanley and deal with the car. If it had stayed toggled to 100% mode it might not have had enough juice to boot much less make a call.

The “Disable” button isn’t even a button. Quite hilarious.

I almost get the feeling that Apple deliberately is trying to make it harder for people to find it... but that’s just conspiracy. Apple would never do that.
 
So now, at the Apple store, when the iPhone gets slow and their battery test passed, they won't send us away anymore without a replacement and tell us to buy a new phone.

Instead, they will tell us to buy a new phone because the button to disable the "feature" doesn't show up yet.

So, basically, it's still apple deciding when you are allowed to preserve the battery and when not. Thats great. What a Change. I'm sure they can be trusted. :rolleyes::D

This is exactly the right thing to do.

It's not supposed to be some toggle they'd want anyone to play with.

Capacity is not equal to voltage. You conflate the two in your message.

It's almost as though Apple wants you to read the disclaimer text before tapping the button.

It's almost as though the correct course of action in the long run is to stop whining about the battery being unhealthy and to get a healthy battery.
 
Even the screenshot shows this stat is redundant/broken. The shutdowns are a result of low voltage, NOT battery capacity. My 6S+ shows capacity of 77% but rarely ever slows down. The screenshot shows a phone with 95% capacity as having battery issues. This annoys me because Apple techs will still likely only look at the capacity to determine if a replacement is necessary. This is a nothing but a barebones implementation of a feature they’re essentially being forced to add.
 
I just installed 11.3 Beta 2 on my iPhone 6 Plus and the battery capacity is 85% and running at full speeds. Still waiting for my battery replacement but my device runs great now. Apple's power management system is a huge overreach on their part. I highly doubt my battery is at 85% capacity either.
 
I've found battery capacity fluctuates between charge and type of charge. I have a user here to thank for that (when the initial storm of commentary happened when the throttling routine was discovered).

I'd been using my iPad's big 13w charger to charge my battery on my iPhone 7+ and found that my battery life expectancy as seen in coconut was less than 100%. My phone hit 500 charge cycles on 2/5.

What someone found is if their phone has been getting lousy battery performance but still a viable battery you could charge with the original charger which charges more slowly and my battery capacity went to 97% from around 90%-ish.

So, it appears that this may be anecdotal but the battery is happier now when charged using the original charger. If I revert to the faster higher wattage iPad charger it charges faster but the overall max charge is less by a handful of percent.

I also wonder if some of the crap aftermarket charging cables I've used for the car might not be a factor. Bursts in charging due to poor cable connectivity stressing the battery could be the issue..

Also, I'm in Minnesota, in the winter. It's been well below zero here for the past 10 days or so. That can't be any fun for the battery either.
