For GRG55

Re: For GRG55

is apple still deliberately throttling older model batteries with each new os update? or did they stop doing that?

I don't know. But I have not felt compelled to install the last two upgrades on my 6S.
I use the phone to make and receive phone calls. And even that is limited as I have no cell coverage at the bunker.
That revelation is apparently a disturbing bit of information every time my cell provider's marketing call center tries to upsell me with offers of new, "must have" services.

I finally broke down and got a cellphone just to have on me in the car. Then I moved and didn't bother to get a landline installed. So now it's my only phone. It's a simple old Sanyo flip phone with a low SAR rating and phenomenal battery life. I just use it for phone calls. Costs me $15 a month at Twigby. Everyone in my contact list has a special ring that I'll pick up. The rest of the world gets the default ring. Those I let go to voicemail because they're almost always telemarketers. I learned that if I don't answer they eventually stop calling.

When I came back from living abroad in 2008 I had intended to charter a sailboat on the west coast and during the trip dump both my cell phone and laptop over the transom into the salt water. Thus forever ridding myself of the tyranny of technology.

Newer versions of iOS now allow users to override the throttling behavior when the batteries are no longer able to deliver the electrical current they could when they were newer. The trade off is that without throttling, the phone electronics could demand a quantity of current that the batteries cannot deliver and will cause the phone to suddenly shut down.

Can the batteries on an iPhone be replaced with new ones? There's nothing else wrong with my phone.

They can if you take it in to an Apple Store. When the throttling issue was discovered and a big brouhaha ensued, Apple did offer battery replacements for a fairly low price. Per the following article, in 2017, the normal price for a battery replacement was $79 but Apple temporarily lowered it to $29 for those customers affected by the throttling. You also might qualify to get $25 as part of a class action settlement.

Re: For GRG55

The batteries in my iPhone don't last that long. I'm on my second iPhone since Oct of 2013. The battery won't hold a charge for more than 3 or 4 hours now. A year ago used to last all day, no problem. So I am wondering if the Tesla batteries are going to have a limited life span, wouldn't we already be hearing about range problems in the older Model S cars - that they don't go as far on a single charge as they did when they were new? Haven't heard anything like that. Has anybody else?

I thought I read somewhere a long time ago that the charge/dis-charge management systems for the batteries was one of Tesla's technical advantages, and that helped it achieve exceptional battery life.

As for the Roadster 2, the official unveil was in November 2017. The Canadian Tesla site is still advertising reservation deposits, including the extra expensive CAN $322,000 Founder's Series, which has a reservation = to the full price of the car. Can one actually take delivery of one of these now?

Lithium ion batteries wear down based on the number of total charge-discharge cycles they've been through. For something like a mobile phone that is used heavily on a daily basis, it's entirely possible that a phone that is fully charged in the morning is down to 10% or less by the time the owner of the phone returns home to plug it into a charger. That means on a daily basis, the phone is going through about 90% of a full charge-discharge cycle. I forget how many such full cycles can be done on a lithium ion battery before it becomes degraded enough that it loses a lot of its charge capacity but I seem to recall the number being 1,000. Thus, at a daily 90% charge-discharge cycle and a "limit" of 1,000 cycles, we're looking at 1,000 / 90% = 1,111 days = 3 years before the battery's ability to hold a charge degrades noticeably.

It is highly unlikely that a Tesla vehicle is going to come even close to hitting 90% of a full charge-discharge cycle on a daily basis. I would imagine a fairly typical commute is 30 miles each way, or 60 miles per day. If the Tesla battery has enough charge for 300+ miles, then we're looking at a 20% charge-discharge cycle on a daily basis, which implies that the Tesla batteries should highly usable for at least five times longer than the batteries in a mobile phone.

Yes. Apple will do it for a high price. There’s also a cottage industry of battery replacement kits with a battery, tools and instructions for 40 bucks.

These days I can see that becoming a growth business...

there are also local stores which [if they're not shut down] will replace the battery and lot more cheaply than an apple store. voids the warranty - not relevant for a 6s.

Re: For GRG55

Yes, very informative, Milton.
My phone gets little use but I wondered if charging it every night to keep the battery topped off was seriously degrading it. You answered my question.
Thank you!

Given Apple's iPhone sales numbers have been flat for about 2 years, and that one product is the critical driver of its ecosystem model, I can understand why it would take a dim view of such a service.

But if, as I expect, one of the outcomes of this economic catastrophe is a secular change in consumer demand and purchasing behaviour, this won't bode well for "sellers of fashion" to Main Street, like Apple. I think the stress on Main Street was already there, and reflected in the sales volume, before the virus showed up.

[Edit added: Implicit in this is my view Apples stock run-up in 2019 and the rapid rebound this year is driven by the combination of huge stock buybacks + the belief it will be one of the protected companies by the Fed and Administration]

i think their current iphone users are captive. it's not easy to escape their ecosystem, although it is possible. so it think they will maintain but not grow sales. their service revenues - itunes mostly- contributed 18% to their revenues [iirc] last year.

Those service revenues are primarily a function of the installed base of iPhone users.

What makes it difficult to escape the Apple ecosystem?

Learning some new ergonomics to switch to an Android phone is understandable, but not impossible (although I tried and dislike the way the Android works - for me less intuitive than Apple).

Is it the apps? And already purchased file content?

As people move more to streaming services, for example instead of buying and downloading a music file from iTunes, is the Apple ecosystem moat in danger of being filled in slowly?
