This year, something unexpected happened: I went to a mid-range Galaxy phone(a52 battery life) and didn’t feel compelled to switch back to a flagship Galaxy phone. Until last year, Samsung kept too many features reserved for its flagship lines. No matter how fantastic the mid-range devices got, they couldn’t match the quality of user experience offered by Samsung’s top-of-the-line handsets.
For the past few weeks, I’ve been using the Samsung Galaxy A52, and it has everything I need in a phone(a52 battery life). Except for a zoom camera, which I’ve already discussed. Today, I’d like to tell our readers about the Galaxy A52’s incredible battery life. Yes, there are other Galaxy phones in this price bracket with excellent battery life, but the Galaxy A52 is unusual in that it also includes a high refresh rate display.
Life of the battery
The following are the criteria of our regular battery test for mobile phones:
- A 720p video is looped with the screen brightness and loudness set to 100%.
- Wi-Fi and Bluetooth are both enabled.
- Email is constantly flooded with information.
In our tests, the Samsung Galaxy A52 5G has a battery life of almost 13 hours, which is the longest among all handsets in its class – except for its A42 cousin, which has a slightly larger battery. It transfers to real-world use, where I don’t feel compelled to grab for the charger at the end of the day (though it’s an excellent habit to have).
As previously stated, the Galaxy A52 5G supports 25W fast charging, albeit the charger that comes with the package is the standard Samsung 15W fast charger. While it’s unfortunate that Samsung didn’t include a 25W charger in the box, we’re glad to see that a good charger for mid-range phones is still included. The A52 does not enable wireless charging, which is standard for phones in this price range.
While I didn’t have the original 25W Samsung charger, I did have a 100W GaN multiport USB-C charger with USB PPS charging on one of the ports. The Samsung Galaxy A52 5G was set in “Superfast charging” mode using that port, and it took only 25 minutes to charge the phone from 56 percent to 90 percent.
Samsung managed to cram a good 4,500 mAh battery inside the Galaxy A52’s 8.4mm, 189-gram chassis. That’s less than the 5,000 mAh found in the Galaxy A32, but it’s an improvement over the 4,000 mAh seen in the Galaxy A51 from last year.
The Galaxy A52 managed a good 105 hours of battery life in our battery testing when set on the default 90Hz “High smoothness” preset. That’s about what we’ve come to anticipate from a phone with the Snapdragon 720G engine and an OLED display with a battery this large.
You might have a look at the Realme 7 Pro as an example. Although it has identical hardware, that should note that it only has a 60Hz display rather than a 90Hz one.
According to our database, while we’re on the subject of consistent chipset performance, the Snapdragon 720G delivered excellent and consistent results in both call testing and standby. Naturally, if you choose the Galaxy A52 5G model with the Snapdragon 750G chipset over the LTE model we’re testing today, you’ll get poorer results in both tests.
We made sure to complete our on-screen video and web surfing testing at different refresh rates, as is our usual practice on devices with high refresh rate screens. In the case of the Galaxy A52, it runs at 90Hz before switching to 60Hz.
One issue to look into with the Galaxy A52’s new 90Hz panel is how much more power the display requires at its maximum refresh rate compared to 60Hz. As we’ve shown before, the difference in power consumption from 60Hz to 90Hz on a modern OLED panel isn’t significant, and the added smoothness is definitely worth the trade-off.
We went to great lengths to playback our offline video in 90Hz mode for the 90Hz testing, which was a complete waste of time. To put it in figures, it’s around an hour and a half of debris that you can and should avoid by simply switching to 60Hz for video watching.
The web browser delta is much less, which makes sense given that changing the refresh rate does not affect the power consumption of the Wi-Fi modem, which is a significant part of the equation. Whereas video decoding on a modern smartphone is a low-effort process for an ARM hardware video decoder, the primary power users in this scenario are the display and speakers.
