Samsung Galaxy A03s review

Display

The Galaxy A03s packs a 6.5-inch PLS LCD display with a droplet-shaped cutout and rounded corners. Samsung has named this panel Infinity-V, if you fancy PR terms. It offers a basic resolution of 720 x 1,600 px or about 270ppi density.

A flat sheet of glass protects the screen, but we have no information about its make.

The Galaxy A03s display has no special features - its refresh rate is locked at 60Hz, there is no HDR support, and it can only show colors within the sRGB range.

We've completed our display measurements, and we captured 488 nits of maximum brightness. There is no sunlight boost in either Manual or Adaptive brightness modes. The panel offers an incredibly deep black level for an LCD, and so it posted an excellent contrast ratio of 1718:1.

The minimum brightness we measured at point white was 19.7 nits - that's rather bright and hence a poor result, but it's expected from such a cheap panel.

There are no screen color options on the Galaxy A03s - you are stuck with what you get. The phone supports the sRGB color space but isn't that accurate - the white and gray hues are bluish, while the rest of the colors are somewhat washed out, dull if you will.

Battery life

The Galaxy A03s employs a non-removable battery with an ample 5,000mAh capacity. It should be plenty enough with that 720p screen and the efficient Helio P35 chip.

Indeed, the A03s aced our battery test and scored an outstanding endurance rating of 122 hours. It scored impressively across all scenarios - calls, web browsing, video playback, and even standby.

Our battery tests were automated thanks to SmartViser, using its viSerDevice app. The endurance rating denotes how long the battery charge will last you if you use the device for an hour of telephony, web browsing, and video playback daily. More details can be found here.

Charging speed

The Samsung Galaxy A03s has a properly large 5,000mAh battery, but its charging capabilities are uninspiring - the phone ships with a 7.8W power adapter (5V/1.55A).

There is no fast charging support. We've tried charging with a 15W Samsung power adapter and got the same charging time as with the bundled 7.8W charger.

So, using the provided 7.8W charger, the phone gets from 0% to 15% in 30 minutes. That's quite slow.

The Galaxy A03s does not support wireless or reverse wired charging.

Speaker loudness and quality

The Samsung Galaxy A03s has a single, bottom-firing speaker. It scores a Good mark on our loudness test.

The speaker quality is not good, though - bass is completely absent, the mid-tones are mediocre, but the high notes sound fine.

Use the Playback controls to listen to the phone sample recordings (best use headphones). We measure the average loudness of the speakers in LUFS. A lower absolute value means a louder sound. A look at the frequency response chart will tell you how far off the ideal "0db" flat line is the reproduction of the bass, treble, and mid frequencies. You can add more phones to compare how they differ. The scores and ratings are not comparable with our older loudspeaker test. Learn more about how we test here.
