False. Android phones absolutely do throttle the CPU secretly with no

You will learn two things about little Jimmy Newton very quickly:
 
1. It changes its name more often than a few here change their socks (those that wear socks).
 
2. It is looking for validation, not discussion.

"It turns out to be a thermal problem. As the app is running the
android battery temperature is rising. At 48 degrees android os has
throttled down the cpu from 1.4 Ghz to 0.8 Ghz."
 
The difference is that the throttling isn't permanent. Unclear if the
same behavior exists for all Androids.

Nope; the Apple feature only activates when the OS detects the battery
is unable to provide needed voltage, which fluctuates and is not
permanent or even constant. You've been fed a lie.

it's not permanent on iphones either.
 
only *peak* loads are limited, where the battery can't source the
necessary current. had that not been done, the phone would likely
suddenly shut down.
 
the rest of the time, when the battery is not being pushed hard,
there's no throttling because the battery is capable of providing the
needed power.

all mobile devices vary cpu speed and other subsystems based on load.
 
to not do so is stupid.

Apple made big changes starting with the 7 with low power and high power
CPU cores, and with the 8/X, The CPU has more dynamic management of
which core is used.
 
So with the 8/X, there is a possibility that the "power management" will
just limit processes to the low power cores instead of throttling the
CPUs.
 
Apple knows how many amps are needed to run the phone, and how many amps
older batteries of certain size can supply. If the needed amps with low
power cores is less than what battery can supply, then no need for
further throttling.

Articles are speculation. And limiting access to high power cores is a
form of throttling anyways (except it doesn't actually slow down the CPU).

Since you're an Apple Apologists, facts are invisible to you.
You do believe in the battery fairy.
 
Meanwhile, the rest of us can see the fact that are *invisible* to Apple
Apologists.

Apple Won't Stop Throttling iPhone Performance
 
<https://www.extremetech.com/mobile/261243-apple-cuts-battery-replacement-costs-wont-stop-throttling-iphone-performance>
 
That article clearly says Apple "won't stop" throttling of *all* newer
iPhones after about one year to about half their original CPU speeds.
 
"The effective cost of buying an Apple device is significantly higher
than it used to be, at least for people who keep their hardware more
than a year"
 
"Apple acknowledges that it failed to properly inform users about the
changes made in iOS 10.2.1 and the introduction of this throttling."
 
Another fact that the Apple Apologists will hate is that this is
an Apple-only problem.
 
"Apple tries to dodge responsibility for its own smartphone designs"
"This is an Apple-only issue."
 
Everyone (but the Apple Apologists) already knew that this problem is an
Apple-created Apple-design problem, where *all* the major Android
manufacturers have gone on record publicy asserting
 
"Android phones do not perform this kind of throttling".
 
Remember, this is an Apple-caused Apple-designed Apple-only problem,
despite nospam's clever hands-caught-in-the-cookie jar Apple Apologists'
attempt at saying Android manufacturers also *secretly*, *permanently*, and
*drastically* throttle CPU speeds of their phones after only one year of
ownership.
 
Everything I state is a fact; but facts are invisible to Apple Apologists.

JF Mezei,
You're one of the rare people on this newsgroup who can converse like an
adult, so I appreciate that you bring up this great point.
 
There's *something* different about the iPhone 6's and 7's that Apple felt
the need to secretly permanently reduce the CPU speeds to less than half
the original in just a year - so - we would *hope* that Apple figured out
what it is that only the Apple CPUs exhibit that kills the batteries in a
year.
 
Let's *hope* they made those changes - but - if they did make those
changes, then why do they definitely throttle the iPhone 7?
 
And why did they *say* they would throttle *all* their phones in the
future?
 
Both those are facts.
 
So if Apple did "improve" the power - why are they still throttling and
planning to throttle the exact phones you say have power improvements?
 
Those two facts don't mix well.

This would be *great* if it is true.
I *hope* it is true.
 
But then we have to wonder why Apple clearly said they would throttle *all*
their phones going forward.
 
Maybe ... and this is just conjecture ... Apple wants to settle the court
cases out of court so they don't want to give the court cases ammo by
admitting wrongdoing ... so maybe that's why Apple *said* they would
throttle moving forward (as if that's "normal" for phones).
 
Dunno. All I can say is that if they did "fix" the power management, then
they wouldn't need to throttle the newer phones - but they clearly said
they would throttle them. So the facts don't line up.

I think Apple learned a lesson here which is they should test their phones
in the real world - and where the real world happens to include weather
colder than it gets in Cupertino and where the real world happens to be
"aged" batteries of at least the warranty period of 1 or 2 years.
 
I'm with you that Apple will likely *fix* this problem because they know
that people have to be thinking that they pay $1000 for an iPhone X and in
just one year, it's an iPhone 1/2X in terms of CPU speeds. That's horrid.
 
Nobody wants half an iPhone X in just one year!
 
So Apple *has* to fix this problem. Remember, despite the FUD that the
Apple Apologists (e.g., nospam & Jolly Roger) try to spew, this is an
Apple-only problem.
 
So Apple needs to understand what they did wrong, and how to fix it.
 
To me, the Occam's Razor answer is they need more realistic battery sizing
or actual "dynamic" (and not just "legally semantically dynamic that is
actually permanent" speed optimization), but, we have to let Apple figure
that one out for themselves.
 
>> iPhones after about one year to about half their original CPU speeds.
 
> Articles are speculation. And limiting access to high power cores is a

Actually, that's *not* speculation. Apple said it themselves. So it's just
the article saying a fact which is what Apple said it would do.
 
I suspect that Apple is playing a clever game (as always), which is that
they will vehemently deny wrongdoing all the while trying to combine the
court cases into a single case that they can settle out of court.
 
I posit that once they settle out of court, they're free to actually
finally admit the truth and fix the problem - but until then - they can't
be open (because anything they admit will be used in court against them).
 
In the end, I think Apple has an *easy* problem to solve which is so easy
to solve that it's not funny. But this is a long post so we can leave the
solution to later.

So I took apart the case of the Bose so I could clean and lube the
laser assembly. Also used some canned blow off gas to blow any dust
out of the area between the laser and the underside of the lens. After
reassembly the player worked beautifully. The one particular CD played
right off the bat. But after swapping it or another CD, which also
played, and then putting the stubborn CD back in, it refused to play.
I noticed that when blowing out the laser assembly the lens would move
down because of the pressurized gas blowing between the lens and
laser. So I pressed down on the lens and tried the CD again. Worked
great. After stopping the player and re starting the CD wouldn't play.
Pressing down the lens carrier on the left hand side of the lens
carrier and then trying to play the CD works. After stopping and then
starting the CD won't play. But then pressing down the lens carrier on
the left side makes the CD play again. Anybody have any guesses why
this is happening? It looks to me like the lens carrier is just
suspended by 4 spring wires. But maybe there is something else that
might be dragging. Anybody know how the things are really made?
Thanks,
Eric

There are two simple solutions:
 
1. A record player with a good cartridge and needle (stylus).
 
2. A MP3 player.
 
If you really are madly in love with CDs, just buy a cheap external CD
player and plug it into the AUX input. My experience with CD players is
this: When they die, they are dead forever..... There is no one on earth
who can fix em'.
(Probably why they are becoming obsolete).
 
If however it's just that one CD that is causing problems, REPLACE the
CD.

> True story: The last place we lived in before leaving NYC was on 190th
Street not far from the Cloisters. Our neighbor had a very elderly
German Shepherd, and she was quite elderly herself. One sad day, her dog
died, and the only place she could take it (in Manhattan) was down
towards Battery Park. So, she bundled the dog into a large suitcase - as
people were wont to own back in the 1960s. Getting into the subway at
190th Street (A-line) is not so hard as there is an elevator from the
street to the platform (well before ADA). However, at South Ferry, not
so much. She faced these steps with an 80 pound dog. What should happen,
but a "Nice Young Man" offered to carry it up the steps for her. And,
promptly ran off with it.

Great Story!
 
That reminds of something a friend of mine did with an old water heater
at his father's suburban Fresno, Ca. home. He and his dad had previously
replaced the unit, as it leaked from a small hole near the bottom on one
side.
 
They both dragged this thing out onto the lawn near the street and
carefully positioned it so the hole wasn't obvious. My friend then
placed a sign on it reading "$50". When he checked later that afternoon,
the water heater was gone.

Thanks for the replies.
 
120 v ac
 
OK on thumbs down to rejuvenation...
 
 
I overly simplified the comments on the power supply which was evidently more confusing than accomplishing a summary.
 
Based on the service manual's description of how the voltages are produced, I offered two distractions. The overview described the +300 V supply as being used for producing the +5 VDC logic supply and the CRT supply as they name it is only +120 VDC. I didn't mean to sound like only measures 120 instead of 300.
 
There was an implied question-how the heck do they run a CRT on 120 VDC? I didn't (yet) see further explanation of internal functions on the CRT ass'y. I hope it's an assembly with the ability to produce all support voltages for a CRT.
 
The diagnosis for CRT problems, as well as other modules, often ends with 'replace the module'...I get 'why?', during the product's heyday, but that leads to a 'problem' period (for wannabe users/restorers) in the future...which is now.
 
I haven't measured anything yet...it's usable, but I'm just snooping around for answers for that day when all the room lights have to be off to see anything. If I'm going to commit space to such a large (and loud!) I'm trying to be proactive.
 
I'll read up on what I can measure without service accessories like extender board etc.

18 years ago. That is one vintage TV, by now.
Typically locked-out channels are a function of the cable box, not the TV. But, if on-board the TV, you will need the password.

Of course we should. But, consider the Golden Rule - those what have the gold makes the rules (forgive the vernacular).
 
As English is the language of Air Traffic Control,
As Greenwich is O Meridian,
 
Initial Events may start as cultural, but as soon as a certain level of commerce and process uses them, momentum does the rest. The first railroads were in Great Britain and the US, and drove the concept of Time Zones and shared standards.
 
Commerce and banking drive years, dates, days, weeks and so forth.
 
Air Traffic Control as it is used today largely developed in WW-II to manage goings and comings on Aircraft Carriers. Although actual formal air-ground communications began in the 1930s in Cleveland of all places. Only the US had any Carriers of any consequence - the system developed, in English, largely in the 1950s with practical and highly efficient radar systems - also developed in/for the military. It is quite likely that "Earth Time" (UTC) will be used (eventualy) for space travel - and for the same reasons. Time Dilation will be an interesting twist on this, however.
