Test: CAT S31 Smartphone (Sammanfattning)

Mike Wobker (översatt av Daniel Eriksson), 01/17/2018

Smart industritelefon. De robusta smartphone-modellerna från Caterpillar, tillverkaren av anläggningsutrustning, tar sig in i nästa runda. På utsidan förblir allt som det varit, men på insidan har en del förbättringar gjorts. I vårt test tar vi reda på exakt vad som är nytt med den extrema utomhustelefonen Cat S31.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9024 (minimum: 43 - maximum: 142900) Hz was measured.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
24.4 ms ... rise ↗ and fall ↘ combined↗ 13.6 ms rise
↘ 10.8 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 34 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.5 ms).
       Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined↗ 21 ms rise
↘ 21 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 52 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.3 ms).

I våra tester så visar sig Cat S31 vara den enhet som tillverkaren utlovar: En robust smartphone som kan klara av nästan alla typer av omgivning. Det faktum att det tekniska innanmätet inte är ifatt den senaste utvecklingen kan accepteras, men eventuella köpare kan tänkas vilja välja den betydligt billigare konkurrenten AGM. Som en ren smartphone så är S31 en instegsenhet med ett stabilt system och stabil prestanda. Enkla appar och webbläsaraktiviteter är inga problem för enheten. Om du vill kan du till och med använda den med handskar på.

CAT S31 är en pålitlig smartphone vars huvudsakliga uppgift är att inte gå sönder. Den uppnår i varje fall detta, men användaren får klara sig utan krävande applikationer.

Valet att köpa en såpass robust enhet beror ofta på magkänsla. Certifieringar och grov design med mycket vinklar erbjuds av alla som tillverkar sådana enheter. Huruvida CAT S31 verkligen kan klara av dom mest extrema förhållandena kan bara ses i ett uthållighetstest för respektive område från användaren. S31 ger oss ett väldigt gediget intryck, men det höga priset kan inte berättigas av endast prestandan och höljet.
