Samsung Galaxy A15 4G review

Display

The new 6.5-inch Super AMOLED screen is the most notable upgrade for the entire Galaxy A1x series in a while. The new panel has 2,340 x 1,080 pixels or 396ppi and supports up to 90Hz refresh rate.

We do appreciate the new AMOLED screen, and it does feel like a proper upgrade over the LCD panels from before. It has a small droplet-shaped notch for the selfie camera, thick bezels and one even thicker bottom bar. There is no information on the make of the protective glass.

We have completed our display test, and the measurements are all right. The new OLED panel offers 372 nits of maximum brightness at the far right of the brightness scrubber - not exactly super bright, but not too low either. The boost from the Auto brightness is significant - up to 808 nits!

The minimum brightness at point white was 1.8nit.

We want to mention that while the screen has no color modes to choose from, the presentation is quite natural and without any obvious blue, red, yellow, or else tint. Nice!

Refresh rate

The AMOLED screen of the Galaxy A15 supports up to 90Hz refresh rate. There are two Motion Smoothness modes - High and Standard. Both offer fixed 90Hz and 60Hz refresh rate modes.

There is no refresh rate drop when using the 90Hz mode even for static picture. The only time we saw 60Hz change was in Camera and Google Maps, among other HRR incompatible apps.

Battery life

Our new Active Use Score is an estimate of how long the battery will last if you use the device with a mix of all four test activities. You can adjust the calculation based on your usage pattern using the sliders below. You can read about our current battery life testing procedure here. For a comprehensive list of all tested devices so far, head this way.

The Galaxy A15 has a large battery with 5,000mAh capacity and one energy-efficient chipset. So, we are hoping for some notably good battery life here.

And it did! The Galaxy A15 scored an excellent active user score of 15 hours and 28 minutes. It aced all of our tests and shines when it comes to web browsing and gaming times.

Charging speed

The Samsung Galaxy A15 supports up to 25W fast wired charging, which is a nice update for the entry-level series. It ships without a charger, as usual. You can use any 25W PD+PPS charger, as it will reach the max charging power supported by the phone.

We carried out our charging test with Samsung's own 25W PD/PPS charger.

It recharged 25% of the Galaxy A15 battery in 15 minutes, while another 15 minutes will get you to 47%. A full charge requires 81 minutes. Those numbers are in line with Galaxy A25's.

Speaker

The Galaxy A15 has a single, bottom-firing speaker. It scored a Very Good mark on our loudness test, and it does sound loud enough outside our tech lab, too.

The audio quality is subpar - the vocals are average, the bass is minimal, and the high frequencies are okay, but nothing impressive.
