realme C55 5,000 mAh battery for over 6 hours of usage
To verify the capacity and strength of the 5,000 mAh battery that the realme C55 possesses, I will conduct a battery test (following the standards of The Gioi Di Dong) to check how long the device can operate with various tasks. This test will be performed under specific conditions as follows:
- Experience 4 rotating tasks including: Playing Arena of Valor (set up as shown below), watching YouTube, browsing Facebook, and using the browser (Chrome).
- Each task runs for 1 hour.
- Screen brightness set to 100%.
- External speaker on with volume at 50%.
- Wi-Fi and social media notifications enabled.
- Battery saver, adaptive brightness, GPS, and Bluetooth turned off.
- Draining from 100% to 0%.
Here are the results of the battery test on the realme C55 that I have obtained:

In today's realme C55 battery test, which can be considered strenuous and crucial, the device achieved a total usage time of 6 hours and 49 minutes. Compared to the average in the budget segment and even when compared to other devices with a 5,000 mAh battery, this result is not particularly impressive. However, the figure is still enough for you to use throughout a long day.

For more details on the battery test, you can see that not only regular tasks but even when playing the national game Arena of Valor Mobile, the realme C55 consistently consumes energy (from 12% - 16% for one task/hour). This is quite good as the difference is not too much. However, for light tasks like using Facebook, Chrome, or YouTube, the battery consumption for a single use is still not impressive. Hopefully, in the future, realme will optimize better for these common tasks.

What about the charging speed of the realme C55? The answer has been revealed in the image below:

To fully charge the realme C55, it takes approximately 1 hour and 41 minutes. This figure is still relatively decent compared to devices with 33W fast charging like the realme C55.
realme C55 battery can handle continuous gaming for over 5 hours
So, if you use the realme C55 for gaming, how long can it last? I've answered this question by conducting a test while playing 4 popular games nowadays: Arena of Valor Mobile, ZingSpeed Mobile, Play Together, and Free Fire to see how long the realme C55 can handle these games!

- Play a single game until the battery runs out.
- Screen brightness set to 100%, and refresh rate set to 90 Hz.
- Turn on the external speaker and adjust the volume to 50%.
- Turn on WiFi and social media notifications.
- Do not enable battery saver, adaptive screen brightness, GPS, and Bluetooth.
- Drain from 100% since unplugging until 0%.
Here are the results I obtained after conducting the test:

- Arena of Valor Mobile: 4 hours and 4 minutes.
- Free Fire: 4 hours and 16 minutes.
- Play Together: 4 hours and 39 minutes.
- ZingSpeed Mobile: 5 hours and 57 minutes.
So, the realme C55 can handle continuous gaming with an average time ranging from 4 to 5 hours. This result is quite good for a device with a 5,000 mAh battery like the realme C55. Specifically, in 3 games: Arena of Valor Mobile, Play Together, and Free Fire, the device can last consistently for over 4 hours. Meanwhile, in the game ZingSpeed Mobile, the realme C55 achieves the highest continuous gaming time of 5 hours and 57 minutes!
