All iPhone 11 Models Feature New Dynamic Performance Management System to Reduce Impacts From Aging Batteries

[gnasher729]

whats the idea behind stopping at 80%? is it harmful to charge all the way up to 100%?

It's slightly harmful if you plug in your phone when you go to bed, at 2am it's charged to 100% and then left there for a few hours. This new feature keeps track at which time you usually unplug your phone in the morning, so it charges to 80%, and then charges up to 100% some time before you usually get up. If you always unplug your phone at 7am, then it might start charging the last 20% at 6am. So this _does_ improve battery life.

What's quiet harmful is a stupid charger that tries to continue charging a battery that is already fully charged. If you have a phone with such a stupid charger, then stopping at 80% does indeed avoid damage. iPhones don't have stupid chargers, they reduce the current used for charging as the battery gets full (as every _decent quality_ phone charger would do).

What's also harmful is a charger that charges to say 80%, then lets the phone run on battery down to 75%, then charges up again to 80% and so on. If you plug an iPhone into the charger (or any decent quality phone), all the power needed to run the phone is taken from the charger, and what remains charges the battery. So there is no wear and tear on the battery from that at all.

Why can’t I choose whether I want the phone to perform well but have short battery life or whether I want it to be throttled? My 6 had issues the last few months and I think it got really throttled. I would have perferred to get the performance as my purse is a mini backpack so I carry a really good battery charger with me at all times and most the time my 6 was connected to it anyways cause throttling or not it had super short battery life (I think it was more related to the cheap eBay part we put in to replace the broken charging port cause my 6 was absolutely fine before that. Plus I got some errors sometimes that seemed to imply the battery was fine but he phone couldn’t get a read on it or something. Though I’m pretty sure with a 5 year old battery and the phone going wonky like that the battery was soon not fine too. Would not have upgraded most likely if that port hadn’t broken and was working like it was before).

Again, if planned obsolescence is the goal, why bother supporting those old phones at all?

So people stay in the ecosystem and eventually feel like they need an upgrade. The device is “supported” but is slow.

I think the planned obsolescence discussion is getting a bit carried away but if you think Apple got to where they are by playing above board the whole way through.. newsflash: all of these companies get their elbows dirty in one way or another. How do people still not know this?

 

[I7guy]

They've taken throttling to a whole new level. In the past the phone would throttle a certain percentage and that was that and it would be easy to tell. But with the new iPhone 11, it has adaptive throttling that may or may not throttle the phone to varying degrees — there's not going to be a definitive way to know how much or if it's throttling at all.
Two years from now as these batteries age there's going to be this gray area of uncertainty as iOS updates and adaptive throttling mess with the phone's performance. There's not going to be any way to know if Apple borked an update, slowing all these phones down, or the adaptive throttling is doing its thing sometimes and sometimes not.

A sure as the sun will set today, there's going to be a lot of confusion 2-3 years from now as people start to experience slower phones but the battery age is at maybe 85-90% which Apple will claim doesnt necessitate a new battery.

This isn't going to end well

There's confusion today. There have been times in the past I recall there were complaints about slow phones, stutter etc, and blamed it on everything except an app, which was the root cause.

This hopefully will extend the life of aging batteries and mitigate more performance issues from throttling.

But no matter, the people who believe that apple purposefully engages in planned obsolescence will again rise this to the fore-front.

The option to disable it if it got turned on is there in battery settings, as I recall.

The real question is: Does an aging battery REALLY equal slower performance???

No, but an aging battery may have more fluctuations is the current it can output. Modern mobile chips dynamically change their current requirements. Based on Apple’s explanations, an aging battery sometimes cannot output enough current when the chip suddenly requires it, resulting in reboots and shut downs.

 

[pika2000]

Failed logic. Apple could’ve simply supported the devices for only two years max if they wanted planned obsolescence, thus people will buy new phones more often. No need to spend the resources supporting 4 - 5 year old phones.

Charging past 80% hurts the battery?

Isn’t this the reason charging slows when the charge level reaches 80%? I though lithium ion batteries don’t like to be at 100% charge for long periods of time. I could be completely wrong, but isn’t this the reason the “optimized battery charging” stops charging at 80% then finishes around the time you are going to use your phone?

Apple also admitted defective batteries can also cause unexpected shutdowns

"Apple has determined that a very small number of iPhone 6s devices may unexpectedly shut down. This is not a safety issue and only affects devices within a limited serial number range that were manufactured between September and October 2015."

Your understanding of this < everyone at Apple who planned and worked on it

 

[Techmaestro]

And iOS 13.1 will being Apples battery throttling to the iPhone XR and XS. I’m sure I remember Apple claiming these phones were more advanced with their battery management, yet here comes the throttling software.
the story was in the Verge, I would post the link to it but this new buggy forum layout won’t let me paste the link..

They will pull the same old trick to make more money and falsely sell customers new iPhones under the belief their old ones are too slow.

I was thinking the same thing. Do we not remember the statement made surrounding the XS and XR’s so-called battery management feature?

Look, I think Apple products are great but I will not fall for the same old marketing speak largely because my brain still works to the point where I can still remember last year’s statements and have the ability to spot trends.

Apple will ALWAYS throttle older devices and the new “Pro” and 11 series will be no different so enjoy your new devices for the next year until your throttling comes and so on and so forth.

 

[Techmaestro]

So you like Apple lying to people to force them to upgrade perfectly fine phones to maximise profits and initiate forces obsolescence?
I think you mean you like the way Apple fleeces and cons its customers to maximise profits.

Exactly! And furthermore, maybe instead of using money for stock buy-backs to drive up their stock price to the tune of over 200 million they could have used that money to truly innovate battery technology.

Oops! Some of you didn’t know that did you? Look it up.

They bought their own stock on one hand and gave you marketing speak from the other.

 

[digthewell]

This is good and maybe Apple should think about making their batteries more reasonably priced in countries like India, where we end up paying well over $110 for a battery replacement. Which is just absolutely nuts keeping in mind how much money that translates to in Indian currency.

So you believe Apple doesn’t have enough money to conduct corporate business and invest in new battery technology?

Because throwing money at battery R&D for 30+ years (Lithium batteries) industry wide hasn’t resulted in a breakthrough, but somehow Apple will change that?

I think Apple is a tax cheat, and stock buy backs are immoral and should be illegal (as they were throughout American history up until Reagan), but you’re barking up the wrong tree here.

Except if throttling kicks in it can be disabled.

 

[TracesOfArsenic]

I’m always baffled that people believe in planned obsolescence. You’re telling me that instead of cutting off iOS updates after 2 years (which is reasonable), they would rather slow down devices and risk a huge pr nightmare? Stupid logic.

The idea behind planned obsolescence is for it to be invisible to users and deniable by the maker. Cutting off software updates after 2 years fits neither of those.

Sounds like everything is a malicious conspiracy with that type of approach.

 

[Tech198]

All designed to keep you using an aging battery the longest

 

[Abazigal]

I guess it’s more that if you are convinced that Apple is out to deliberately screw the customer over, then everything Apple does will somehow always seem that way, however pure Apple’s true intentions may be.

Incorrect.

Throttling is better than shutting down, like android does.

I don't understand why you keep mentioning tha Android phones just shut down if the battery can't provide the required voltage.
Can you actually prove this claim with links?
Because I can paste a few lines for Android's source code that shows that you are wrong but I'm willing to give you the benefit of the doubt if you have links that can support you claim.

Should be easy to see if doing a web search on “android battery shutdowns “ or some such thing or variations. If no results then I’m wrong.

 

[M3gatron]

No offense but that's not what I asked you.
I asked for proof that Android phones simply shut down instead of throttling. What you mentioned is at best something anecdotal and not some definitive proof that supports your general claim.
So can you provide such proof? Yes or no.
