No.
 
Whether the battery is brand new, or three years old, if it's in a low
state of charge it could shut down under heavy processor demand.
 
Here are the good choices:
 
1. Shut the phone down before the battery is discharged to a level that
would cause an unexpected shutdown if high demand were placed on the
battery. If this event occurs after an abnormally short amount of
operating time, inform the user that a battery replacement is needed.
 
2. Reduce performance only when the battery is discharged to a level
that would cause an unexpected shutdown if high demand were placed on
the battery.
 
3. Give the user the option of a "battery-saver" mode that would reduce
performance in order to increase the operating time.

That would needlessly reduce performance in most use. A lot of devices
are now designed with thermal sensors that allow a performance level
that cannot be sustained for long periods of time under certain conditions.

state of charge is not the issue. it's aging to where it can't supply
peak loads anymore, even if it's at full soc.

that exists now.

that's what apple is doing (and some android makers even though they

Still using an old iPhone 4S with its original battery. I don't use it
much. Its batttery life does suck badly (e.g., could shut it down within
30 minutes with Pokemon Go), but the key part is not to use it often and
under control. Also, I keep its cellular, backaground apps, etc. in
control. I wonder how much longer I can keep using it before replacing
it or its battery (probably not worth it since its iOS is so old, slow,
and unsupported).

Classic Apple Apologists distort reason because facts shake their belief
system to the core.
 
Saying all batteries degrade with time and use is correct, but only Apple
iPhone batteries consistently fail within a year such that CPU speeds need
to be halved to "prolong the life of the iPhone".
 
The Apple Apologists are making an analogy akin to saying all people age
and die, so what does it matter if a huge number of them die within a year.

I agree with your logic, rickman, but you're dealing with Apple Apologists
whose very belief system is shaken off its foundations when the truth about
Apple is revealed to them.
 
I just supplied a quote that says only Apple iPhones "begin to fall apart
after a year", which is the main point. In Europe, that's within the
whole-phone warranty period, and certainly within the whole-phone warranty
period of the Android LG Stylo 3 Plus phones I bought over Christmas.
 
The point is that a year is too soon, and it only happens, en masse, with
Apple, and Apple is the ONLY manufacturer who throttles the CPU with an iOS
update (secretly in the past, and more openly in the future).
 
Basically, you must logically *halve* any benchmark for an iPhone, if you
plan to own an iPhone for more than a year.

The scientific question is how do we correctly interpret why EE pads seem

In another thread today, the topic was discussed on how to intelligently
select friction materials for replacement brake pads and shoes.
https://s18.postimg.org/wqilqasdl/toyota_friction_material.jpg
 
That discussion hinges on a scientifically valid interpretation and
understanding of the utility of the "friction codes" printed on every brake
pad and shoe in the USA:

Here is the original response to that thread where it was said that SAE
J866a Chase Test EE pads outperformed FF pads.
<https://groups.google.com/d/msg/rec.autos.tech/_SSZmTXS5kk/87MU4e1JAAAJ>
 
>I can't run my own tests like the police did here:
>https://www.justnet.org/pdf/EvaluationBrakePads2000.pdf
 
And those tests showed the EE pads CONSISTENTLY outperformed the
FF brakes pretty well across the board - with the FF brakes
SEVERELY underperforming in most cases.
 
The Dana Ceramic family was the only FF to outperform OEM, while
HawkHead outperformed on both Chevy and Ford - and Raybestos and
Carquest alsooutperformed on Ford in the panic stop test.
 
Across the board, EE brakes, on the whole, outperformed the FF
and even the EE/GG combination - so what does your friction
rating tell you????????????
 
What it tells ME is if I buy Raybestos, NAPA, CVarquest, or Dana
(all major OEM suppliers) brakes, I will equal or excede OEM
performance - doesn't make a bit of difference to me WHAT rating
they have.
 
If I want slightly superior hot panic braking, at the expense
of poorer cold and medium temperature braking I should buy
ceramics - and this is STRICTLY for braking performance.
 
Now, from REAL WORLD experience, both myFord Aerostrs went
through rotors like crazy - untill I put on NAPA's Carbon
Metallics a set of pads destroyed a set of rotors at about
half of pad life - and I mean TOTALLY DESTROYED, here in
Southern Ontario. That came out at just over a year.
 
When I went to NAPA Carbon Metallics, the same rotors lasted
for TWO FULL SETS of pads - and over 5 years - and I was able
to actually lock the front wheels on dry pavement (rear ABS only)
- which NONE of the other brakes were capable of doing.
 
Never looked at the friction rating - never needed to,
because friction rating doesn't tell the whole story
(as your reference so elegantly proved)
 
You can have 5 different FF pads - and one will be noisy as hell, one
will eat rotors for lunch, onde will corrode as soon as it SMELLS
salt, and another will turn to gravel the first time you get it hot -
ALL FF rated (or ef, or ee. or FE )
 
The fact it met the test requirements ONCE in the lab means NOTHING
about quality

The engineer's enigma.

And that's with "genuine" parts (we will "ass u me")
 
Now google "counterfeit brake parts" - or just "counterfeit auto
parts" - and you will see how big a problem parts counterfeiting is
world wide, and why those ratings stamped onthe brakers do not
NECESSARILLY mean ANYTHING.
 
That's why I say buying known brand parts from a trusted supplier is
the FIRST step in getting good parts.
 
Assuming coefficient of friction IS the main quality you want in
brakes - which for me it most definitely is NOT.
 
I want quiet brakes that respond smoothly both hot and cold, last for
a good length of time, and do not destroy my rotors/drums.
On disc brakes I want pads that don't dust excessively, and the dust
does not attack the finish on my alloy rims or wheel covers.
I want brakes that do not fade excessively, and that willprovide more
than adequate braking in real world conditions.
 
When I installed oversized tires on my Ranger, brake effectiveness
deteriorated significantly - with the same brake pads and rotors.
I'm no engineer - but it was not hard to determine the problem was a
problem of leverage - the big wheels were exerting more foot-lbs of
torque to the brake - and the answer was bigger rotors - NOT different
brake pads - or even bigger brake pads. Just move the brake pads 10%
farther from the axle, like the larger wheels moved the road contact
area about 10% farther from the axle, and the brake force was
re-ballanced.

This is a difficult question to answer, where *Xeno the troll* clearly
isn't capable of answering it, but neither am I, which is why I asked for
scientific help.
 
We're talking about EE and FF pads as determined by the SAE J866 Chase Test
http://standards.sae.org/j866_201201/
 
And, we're talking about EE/FF pads being tested in the *same vehicle*,
where one must note the friction coefficient of E is marginally above that
of steel on steel (i.e., no pad at all).
 
Hence it is an enigma if the EE lower-friction coefficient friction
materials can outperform FF higher-friction coefficient materials in
real-world tests.
 
However, it is true that the link above says, very clearly:
"Due to other factors that include brake system design and
operating environment, the friction codes obtained from this
document cannot reliably be used to predict brake system performance."
 
So the only scientific question here is why would EE outperperform FF?

While counterfeit parts "could" be the problem, do you really think that a
state-run test posted and published nationally, would fall prey to them?
 
I think that fails Occam's Razor for logic (unless you have proof).

> That's why I say buying known brand parts from a trusted supplier is

But we can assume the police did that - where it's just not reasonably
logical that they would fall prey to a plethora of counterfeit parts,
especially since the parts were *supplied* by the manufacturers, I believe.
 
(We could fall prey to "ringers" though...)
 
> Assuming coefficient of friction IS the main quality you want in

I have to openly admit that I think the coefficient of friction is one of
the critical factors in brake friction materials, other than fit and
"reasonable" everything else (longevity, noise, dust, etc. in the Bell
Curve).

Everyone wants that, so we all agree (except trolls like Fox's Mercantile).
 
But how do you know that from the numbers printed on the pad?
(Rhetorical question - as I know there's no way to know that.)

Why wouldn't fade be covered in the SAE J866 Chase Test, which tests their
friction coefficient at a variety of temperatures?

I agree that there are *many* factors in the act of slowing down a vehicle
with brake friction material heating up causing a loss of the energy of
momentum.
 
However, the cold & hot friction coefficient, logically, must be a primary
factor, where there's a reason if lower coefficient EE pads (which have
just barely better a coefficient of friction than no pads at all) could
outperform FF pads (which have appreciably higher friction coefficients) in
the same vehicle under standard tests.
 
All I ask is how this can happen (where counterfeits are not logically the
reason).

Yeah, ain't modern medicine great? My wife was saved by a good doc
after her appendicitis was mis-diagnosed by a quack. My older brother
would have died long ago if it wasn't for surgery to remove a chunk of
colon that would have killed him from cancer. I avoided paralysis by
about 6 months from stenosis. My wrists both move after being crushed.
All that hardware they put in to hold all the tiny pieces bone is
pretty impressive. I am a year out from being declared most likely

All my life I've been healthy. Organs fine, rarely get sick. My eyes
suck and I have minimal aerobic capacity (neither does Dr. Michael
Mosley [Brit presenter of very good medical programs, definitely worth
watching]) which has limited my athletic performance and I have some
protruding disks which are a nuisance, but not debilitating. I get
pissed when I have something wrong and just expect to have everything
work. Goddammit, I pay enough for medical insurance, it should damn
well WORK!!!!
 
I just had my cataracts done because of lifetime unclear vision, not
anything having to do with the cataracts themselves.
