Battery Testing Procedure and Outcome
The testing will be conducted in three sessions, each simulating different professions and diverse usage habits. After each trial, we will note the on-screen time of the device. Once all three tests are completed, the average on-screen time will be calculated to yield the final outcome.Session 1: Playing smartphone games predominantly. Of course, still maintaining other tasks like web browsing, Facebook, Instagram, or watching Youtube
Result: On-screen time achieved 5 hours and 20 minutes.
I predominantly played games like Arena of Valor and a few other small titles. In these games, I always set the graphics to the highest possible level. Besides gaming, I also carried out basic tasks such as web browsing, Facebook, watching YouTube, or responding to messages with friends through various chat apps.
For usage like this, according to the statistics from the first full charge, I got a total of 17 hours and 23 minutes, and the battery was at 10%. The Always On Display (AOD) feature and the dynamic wallpaper I use consume a considerable amount of battery, as you can see in the attached image.Session 2: Using the phone extensively outdoors, connecting to 4G, and taking photos. Of course, still maintaining other tasks.
Result: On-screen time achieved 5 hours and 35 minutes.
After completing the recording, I use LR and CapCut apps to edit photos, cut videos, etc. These are typical tasks performed by someone creating content on their phone. For this usage, including standby time, I was able to use the phone until it had 9% battery remaining, totaling 22 hours and 16 minutes.
Day 3: Playing the role of an office employee, primarily using the phone for calls and light entertainment (web browsing, Facebook, Instagram, or watching Youtube)
Result: On-screen time achieved 5 hours and 43 minutes.
After conducting tests three times with various usage scenarios, the average on-screen time achievable by Xiaomi 13 Ultra is approximately 5 hours and 33 minutes.
Regarding charging speed, Xiaomi 13 Ultra supports 90W fast charging, and the total time to fully charge the battery is about 40 minutes or takes around 15 minutes to charge from empty to about 56%. Overall, I assess the battery life of Xiaomi 13 Ultra as good; the device can handle a day of usage, considering settings that somewhat stress the battery like high screen brightness rather than 50%, maximum resolution and refresh rate, and using 4G,
