Is Apple slowing down your iPhone?

by Volker Weber

It's pretty easy to find out. Download Geekbench 4 and run the CPU test. Compare your results against typical results for your type of device.

iPhone 6 - 1400
iPhone 6S - 2300
iPhone SE - 2400
iPhone 7 - 3400

This includes the Plus models because they have the same CPU. If your numbers are way lower, than you will need a new battery, which will soon become available for 29 € in Europe and is already available for $29 in the US.

This iPhone 6 clearly needs a new battery.

Volker, are you talking about the Single-Core Score or the Multi-Core Score?

Stefan Dorscht, 2017-12-30 23:16

Single-Core.

Volker Weber, 2017-12-30 23:21

Ok, got it. Think first, then ask. ;-)

But what are the margins? What is "way lower"?

And one more: does the iPhone have to be charged to specific percentage?
With 28% battery left I´ll get 1787 with an iPhone 6S. Way too low?

Stefan Dorscht, 2017-12-30 23:23

Yes, that is about 25% drop in performance.

iPad Air 1338 at 13 % Battery.

Looks like it is not supported by performance optimization.

You said you read the open letter. It states that only iPhone 6, 6S, SE and 7 have this feature.

Volker Weber, 2017-12-31 00:11

volker, yes, you are right.
I was just playing with geekbench.

Given the communications strategy of apple, we will never know, why these older devices are not supported by this performance thing, while also supported by ios 11.x.

My old 5s shows the symptom of "sudden death" when battery is below 20 %.
Maybe i should give it a new battery (althoug not qualified for reduced price), as it's performance is ok for me.

Perhaps we will see more information when that new ios version is released.
Or not.

I think the 5S needs to be retired. You will still make some money when you sell it.

Volker Weber, 2017-12-31 07:33

Is the same happening to iPads?
I couldn't find any references :(

Only iPhone 6, 6S, SE and 7 have this feature. 8/X are too new and iPads have very large batteries that should always be able to feed the CPU.

Volker Weber, 2017-12-31 10:39

my 8 plus is faster in single-core than my x. Is Geekbench reliable?

Karl Heindel, 2017-12-31 11:29

Am besten funktioniert die Frage, wenn Du uns einfach Deine Werte sagst.

Durchschnittswerte:

iPhone 8: 4216 - 10112
iPhone 8 Plus: 4216 - 10171
iPhone X: 4203 - 10104

Mein Werte:

iPhone 8 Plus: 4270 - 10404
iPhone X: 4244 - 10330

Die Abweichungen zwischen diesen Werten sind nicht signifikant und auch nicht zu spüren.

Danke für den Tipp. Für die Kostenlosfraktion tut es auch der Antutu Benchmark. Etwas 3D-lastig, aber auch die CPU wird getestet. Nach dem Testdurchlauf kann man sich das Ergebnis im Vergleich zu anderen Geräten anzeigen lassen und seine Schlüsse daraus ziehen. Mein SE schlägt sich noch wacker. BG

Patrick Möller, 2018-01-01 10:55

Die Kostenlosfraktion soll sich in Grund und Boden schämen. Nur ja nichts für Software ausgeben ... nicht mal einen Euro.

Volker Weber, 2018-01-01 11:32

Seems to be some variance in results, which is a surprise.

My iPhone 7 Plus makes 3510 consistently. Its listing 3306 as the Iphone 7 Plus comparison. Anyone able to explain the divergence?
