Less charge means lower voltage on a battery. Lower voltage means less ability to arc across a gap.
I don't know how close those battery terminals are; but at 10 kV per inch dialectic constant in air, either the batteries are rated at thousands of volts (not), or those battery terminals are awfully damned close.
No, this is just a way for Slamdung to reduce their liability and look like they are " doing something", while the world waits months on end-to never for another phone.
In other words, perhaps this is why iPhone 7 orders are FOUR TIMES the previous model (and THAT without a 3.5mm Jack!).
I thought most modern devices have moved beyond LiIon to LiPo and all Li devices should maintain their charge due to memory effects, even in modern batteries.
Li-ion and Li-Po batteries have a MUCH reduced "memory effect", relative to earlier Ni-Cad and Ni-Mh batteries. But they DO have the effect to some degree. That 's why Apple encourages users to do a full discharge-recharge cycle at least once a month.
I'd love the option to set my various devices' charge/discharge limits to 90% / 10% or 80% / 20%.
Yes, Li-Ion chemistry has improved a lot in the past decade but batteries still degrade faster at 100%.
That's why Apple has charged their Li-Ion and Li-Po batteries to around 85% for like, forever. As a result, all my various Apple gear has almost identical (and stellar) battery life as the day I got it, even my relatively ancient iPad 2, that I am typing this on. Been using it for around 4 hours continuous mail and web stuff today, and it's sitting at 91% right now.
Apple also encourages users to do a full-discharge-recharge cycle at least once per month (my iPad sees that about once or twice a week), and has an OS counter that shows when the last time that happened. They also point out that keeping the battery from overheating is also key to long battery life. Car chargers are notorious for blasting batteries. For that reason, I use my car charger as seldom as possible, and never charge my iPhone over about 50% with it (which fortunately? Only takes about 20 mins).
After the article about Sony boosting battery life ( https://hardware.slashdot.org/... ) I started looking for a way to stop my phone from charging past 80%. I was hoping to find an Xposed module that covered it, but no such luck. There don't seem to be any apps to do it, either.
Its interesting that Samsung cobbled together something to do it. I wonder if it is hardware specific, or can be exported to other devices.
Apple routinely charges all batteries in all systems to around the optimal level of 85%. Has been doing that for years. Maybe that's why all of my current Apple gear, including my 2013 MacBook Pro, iPhone 6 Plus, iPhone 4s, and even the relatively ancient iPad 2 I'm typing this on, have virtually the same battery life as when they were new. For example, my iPad, which sees HEAVY use every single day, still gets over 10 hours of typical email, web browsing, etc.; actually probably closer to 12 hours.
With Li-Ion and Li-Po batteries, the key really IS the charging profile, and nobody else but Apple seems to understand that. Don't know why; but it seems to be true.
IMHO at this point the solution is regulation to prohibit vertical integration. Phone manufacturers make the phone and only the phone. OS vendors only make the OS. App makers only make apps.
Not only is that illegal; but it flies in the face of Apple's iOS business model. And in case you haven't noticed, their's is the ONLY mobile ecosystem that DOES work, especially when it comes to handling issues like timely software fixes.
"Samsung is in talks with telcos from nine other countries where the phablet is available to deploy a similar software upgrade."
This is a great example of just how broken Android really is. If it was Apple (and MS?), everyone would get this right away, but instead it has to be dealt with carrier by carrier, and if your carrier decides not to allow for the patch ("bandwidth!"), Samsung decides not to work with your carrier, or someone misses an email you won't be getting it at all.
Telcos should have zero say in when or how you update your device, or have any say in what you do with it in the first place.
Actually, I was thinking how this proves that Android actually CAN push an update in short order... When it suits THEIR purposes.
Samsung deserves every single lost sale because of this.
Meanwhile, iPhone 7 orders are FOUR TIMES of the previous model. Wonder if it has anything to do with the fact that, for a LOT of people, this is the last straw with Android and their shitbox... Well, EVERYTHING?
Didn't we see an article about exactly that a few days ago? A company talked about not allowing Lio-Ion batteries to charge to 100% to increase their longevity?
Forcing a shutdown when the batteries are at 10% would probably help too, but there's the fact that cellphones can be used in case of emergencies so it's probably not a good idea.
IIRC, the magic number is around 85% max charge. 60% is just pure CYA.
But then, Slamdung never could design a decent charging circuit. My work Slamdung laptop burned its batteries to a crisp in short order. Even with using its fancy "Samsung Power" (or whatever the fuck they called it) charging profile, which supposedly stops at 80%, I can get only about 10 minutes (at best!) without having to "plug in or find another power source".
"But there is no way you can get that down to your ten cents, no way, no how, no place."
You must not know nothing of Alibaba/Aliexpress. I can get several thousand dollar faceting machines for twenty bucks. Bulk headphone jacks are two fucking cents in quantities of 1,000 or more.
Embedded developer != Sourcing Manager.
Alibaba/Aliexpress sells surplus crap. It is not a serious source. Their shit comes and goes on a weekly basis. Great for a prototype run to get a bunch of A/C adapters for cheap; but no serious company would EVER source from their fly-by-night vendors.
And a hobbyist who sources stuff from Digikey and Mouser is not a procurement department for a multibillion-dollar corporation.
And an embedded dev may not be a "sourcing manager"; but working ones generally have to work hand in hand with them.
I love how your lack of logical rebuttal below denotes your feeble mind. That's all children can do, after all, throw insults without any logical thought behind it. Typical behavior of an Apple user.
Been an embedded Dev. For nearly 4 decades; so I guess I DO know jack shit about BOMs and cost reduction. But there is no way you can get that down to your ten cents, no way, no how, no place.
And if Apple wanted to kill off alternative payment dongles that depended on the headphone jack, they could have done that without even touching the hardware, you imbecile. And what are you going to say when all those payment dongles simply switch to Bluetooth, or are redesigned for Lightning?
You really don't understand how all this stuff works, or you wouldn't have included that link to that ridiculous, paranoid-induced image.
Here's a thought: if the audio jack is going to be outdated within a year, then why does literally every guitarist the world over still use analogue cables? I understand, those are quarter inch jacks, and you may think it's "different" but it's not. Apple is just trying to build a better mousetrap again without realizing that the best mousetrap is already used by everyone.
That IS quite different; and if you understood guitar electronics, you'd know why.
First, let's discuss the guitar itself: Even today, many guitars are not only entirely analog; but they are often "passive". That is to say, they have no "active" electronics. So, it wouldn't really be practical to retrofit those guitars with batteries and electronics necessary to make them have a digital output. And you would also be giving up some of the sounds that come from the subtle interplay between the guitar pickup and the "front end" circuits in the guitar amp.
And If you are saying that they should change their output to a digital format, then you make them incompatible with the WHOLE of guitar amplifiers and effects. Since those are ALL equipped with analog I/O for the main signal path, absolutely no advantage would be gained, because the guitar's digital output would have to be converted immediately to analog; thus losing any advantage of a digital signal path. Add to this the fact that many, many guitarists actually prefer old technology such as tube-based amplifiers and old analog effects (mostly because of "mystique", IMHO), and you have the epitome of "just because you can do a thing...".
But if you offered at least some of those same guitarists a relatively practical way to use a more reliable connector than the standard 1/4 inch "phone" connector, you would find at least some of them would jump at the chance! Why? because almost EVERY guitarist has had more than one annoying run-in with that "wonderful" connector.
Like with the 3.5mm "phone" connector on earbuds and headphones, and the 1/4 inch versions before them, the problem is actually most often with the JACK, not the PLUG. The contacts get bent back, from accidently applying side-load on the cables, plus crud and oxide and bar-smoke deposit themselves on the contacts (and on the plugs, too), making the connections either annoyingly intermittent, or worse yet, actually act like the diode junctions in an old crystal radio set! That's right, a bad guitar Jack can actually pick up AM radio signals!!!
And by the way, there have been a few guitars, such as the Gibson Les Paul Studio guitar and bass, that used a different connector (in that case, an XLR connector), and despite its problems, the 1/4" phone connector is simply used because it is simply used; but it is NOT because it is the BEST connector that COULD have been used. Maybe when the first electric guitar was invented; but CERTAINLY not now.
If you don't think nine dollars for a 10c device isn't a money grab them by all means, hand over your money $9 at a time.
I don't think that nine dollar retail for a two dollar device is a money grab; it's about typical.if you think they are producing that adapter (which has a custom microcontroller with DAC in it) costs closer to two dollars than 50 cents landed costs, you have never even been peripherally involved in product design.
If the adapter allows charging at the same time, I agree with you. If it doesn't, you fell for it. Once you can't listen to music at 4% battery life you'll buy bluetooth. The ones included, perhaps, but that gives market saturation. The situation is clear to anybody that has released new "features" that close out old functionality. We used to call them engineering releases, usually just after a point release.
> every single person
False, unless the iPhone 7 comes with a battery that lasts for days without recharge. What you meant to type was: "every person with my usage profile".
Even people who can cope with not being able to charge their phone while using headphones will suffer a reduced product life as the battery reaches its limit of charge cycles much earlier.
IOW, you couldn't be more wrong.
What does this have to do with charge cycles? That's not the way LI-ion batteries work.
Until Apple remove it and replace it with their own "Bluetooth-like" technoloshit.
From what I can tell, the W1 chip is basically just an early BT 5 modem, and since Apple already stated that all W1 equipped devices had upgradeable firmware, my feeling is that they are just waiting for BT 5 to be finalized (it's close enough now that only minor tweaks will happen, if any at all), and then they will have nearly a one year head start over everyone else on BT 5. Kind of like what happened when everyone had 802.11n stuff before the spec was official, and then just blew some new firmware into the stuff to make it support the official standard.
What happens when they take away your USB support? I guess you'll have to buy a new Jeep to get USB type c right? That will be fine. The solution is yet another dongle right? But what about the limited power draw on classic USB 2/3?
People forget that 3.5mm socket has become common on phones only in the last decade. Nokia, Sony, Motorola supplied their headphones with proprietary connector or you could buy a 3.5mm converter.
You're absolutely right! I forgot all about that horrid little adapter on my Motorola or Nokia phone, and then, it only went to a 2.5mm Jack. Getting to a 3.5mm meant yet another adapter.
What confuses me though is why you are looking to buy a new Mac Mini if the one you have still works. Is it broken?
Especially since it looks like a 2012 mini will be supported for probably at least 2 or 3 more major OS revs, and even then, will likely be a new enough OS when it is finally unsupported to still be viable for another 5 years or more after that. By that time, even a dual core Mac mini will be significantly faster than that quad core one.
Slashdot Mirror
They're offering customers 100% of their money back, the trouble is getting people to actually return the recalled phones.
Especially the guy with the burned-up car...

Or maybe it was the last dying twitch of his Posting-finger...
Less charge means lower voltage on a battery. Lower voltage means less ability to arc across a gap.
I don't know how close those battery terminals are; but at 10 kV per inch dialectic constant in air, either the batteries are rated at thousands of volts (not), or those battery terminals are awfully damned close.

Your 60 percent of a phone has a headphone jack.
LOLOLOL. That's GREAT!

LiPo didn't solve the LiIon degradation issues. The issues have nothing to do with memory effect.
Not when you have OEMs that could care less about your long term battery life, and sacrifice everything for fast charging times.
