Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 384.6 Hz | ≤ 10 % brightness setting | |
The display backlight flickers at 384.6 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 10 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 384.6 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured. |

Omdöme – Så billig men ändå så kraftfull
Läs den fullständiga versionen av den här recensionen på engelska här.
Xiaomis Redmi-telefoner är prissänkare - de fortsätter att flytta fram gränserna för sitt prisskikt: Redmi 7A kostar runt 1.000 kronor (beroende på konfiguration) och har funktioner som vi vanligtvis bara ser på telefoner som kostar dubbelt så mycket. Som exempel använder telefonen en Snapdragon 439, en kraftfull SoC som ger hög prestanda för pengarna. Riktigt lång batteritid, utmärkta högtalare och möjlighet till att spela spel rundar av uppsättningen av utmärkta funktioner. Kameran tar skapliga bilder, skärmen är ljusstark och värmeutvecklingen vid belastning går att tolerera. De nya färgalternativen ger Xiaomis telefon en fräsch och modern look och den är dessutom bekväm att hålla i. Tack vare en snabbladdningsfunktion laddas telefonen dessutom kvickt.
Det är en ganska stor samling styrkor för en såpass billig enhet och det finns knappt någon konkurrent i det här prisskiktet som kan matcha det. Telefonen slår till och med sin föregångare med längre batteritid och ökad prestanda. Det är synd att Redmi A-modellerna inte kommer med en fingeravtrycksläsare. Den har dessutom en oprecis GPS och röstkvaliteten låter en aning dämpad.
Om du letar efter en billig smartphone men ändå vill ha bra prestanda och lång batteritid kan Redmi 7A vara telefonen för dig.
Vi kan definitivt rekommendera Xiaomi Redmi 7A. Kolla bara så du köper en global version från en pålitlig återförsäljare, annars kan du få problem med AC-adaptern och garantin.
