Samsung Galaxy A73 Battery Life + Recharging Speed!

Take a look at the Samsung Galaxy A73 smartphone’s battery recharging speed, and find out how its two refresh rate options affect its battery life!


Samsung Galaxy A73 : Refresh Rate Options Affect Battery Life

The Samsung Galaxy A73 smartphone offers two refresh rate options (Settings > Display > Motion smoothness) :

  • High : Get smoother animations and scrolling with a 120 Hz screen refresh rate
  • Standard : Get longer battery life with a 60 Hz screen refresh rate

You may think that this is similar to the Galaxy S22 Ultra’s 120 Hz display, but you would be wrong.

The Samsung Galaxy S22 Ultra has an Adaptive mode that dynamically refreshes between 1 Hz and 120 Hz for better battery life.

The 120 Hz refresh rate option in the Galaxy A73 is fixed at 120 Hz. This guarantees you an ultra-smooth 120 Hz refresh rate all the time, at the expense of battery life.

In the next section, we will look at how the two refresh rate options affect the Galaxy A73 smartphone’s battery life.

Samsung Galaxy A73 : Battery Life Comparison!

The Samsung Galaxy A73 comes with a large 5,000 mAh battery, which is the same size as the Galaxy S22 Ultra’s battery!

To test its battery life, we turned off Automatic Brightness, and set its display brightness to 50%.

Why 50%? That is actually slightly higher than the average indoor brightness level of 40% during the day, and is what we usually use in all our mobile battery life tests.

It is important to fix the brightness level, to make sure the screen brightness does not change as the ambient brightness changes.

We then ran the PCMark Work 3.0 battery life test until its battery capacity dropped to 20% several times, and this was the best result we obtained with 60 Hz and 120 Hz refresh rates :

Look at that! The Samsung Galaxy A73 has a long battery life of 10.75 hours with High refresh rate enabled, and lasts 13 hours with the Standard refresh rate!

That means it has the same battery life as the Galaxy S22 Ultra with the 120 Hz refresh rate, but one hour shorter battery life at 60 Hz.

That’s the advantage of the S22 Ultra’s more efficient 4nm processor, but then again – the S22 Ultra costs a lot more than the A73!

Standard Refresh Rate (60 Hz)

The Samsung Galaxy A73 delivers the best battery life with the Standard refresh rate of 60 Hz, offering just over 13 hours of non-stop use.

The Galaxy A73 consumed 13% less power than the S21 Ultra, but 9% more power than the S22 Ultra.

High Refresh Rate (120 Hz)

Switching on the High refresh rate of 120 Hz cut its battery life by 18% – almost 2.5 hours!

But Galaxy A73 has pretty much the same battery life as the S22 Ultra, and last year’s S21 Ultra.

Samsung Galaxy A73 : Battery Recharging Speed!

The Samsung Galaxy A73 supports up to 25 watts of wired fast charging, but unfortunately, does not come with the charger in-the-box.

So we relied on the standard 15 watt Samsung fast charger than shipped with their previous smartphones and tablets – something we believe most users will end up doing.

Recharging Speed S21 Ultra S22 Ultra A73
Battery Capacity 5,000 mAh 5,000 mAh 5,000 mAh
Charger Output 25 watts 15 watts 15 watts
Battery Life 64 minutes 64.5 minutes 85 minutes
Recharging Speed
(per minute)
62.5 mAh 62.0 mAh 47.0 mAh

Despite having the same capacity battery as the Galaxy S22 Ultra, and using the same recycled 15 watt charger, the Galaxy A73 recharged about 25% slower.

That shows that even though their batteries have the same capacities, they are built differently, allowing for faster charging on the Galaxy S22 Ultra.

That said – the Galaxy A73 was no slouch, taking less than 1.5 hours to fully recharge from 20% to 100%.
