Reviewing Xiaomi Mi 11 5G's battery life across tasks
For basic tasks,
First, let's experience the battery life of Xiaomi Mi 11 5G in fundamental tasks that everyone uses daily, including Google, YouTube, Facebook, Messenger, and Zalo. For these tasks, we'll set up the device under the same conditions to get the most objective results (screen brightness 100%, using headphones, 120Hz screen, and Wi-Fi connection).
The continuous usage time for the 5 tasks mentioned on the Xiaomi Mi 11 5G from 100% to 0% battery:
- Chrome: 09 hours 58 minutes.
- YouTube: 07 hours 49 minutes.
- Facebook: 08 hours 43 minutes.
- Messenger: 08 hours 40 minutes.
- Zalo: 08 hours 35 minutes.

Of course, no one has the leisure to continuously use onscreen just to watch YouTube or scroll through Facebook. So, if you're flexible in usage during idle time, Xiaomi Mi 11 5G can likely last more than a day. Once again, note that we are evaluating basic usage here.
For high-intensity usage,
High-intensity users looking to buy the Xiaomi Mi 11 5G aren't just for scrolling Facebook, reading news, or taking pictures but also for gaming. This time, let's conduct the battery test for this flagship with a cycle of tasks from playing Arena of Valor -> watching Youtube -> scrolling Facebook -> browsing Google Chrome -> continuing with Arena of Valor -> Youtube -> Facebook. Of course, the device settings remain constant during task switching.

With the screen brightness set to maximum, the display at 120Hz, and no power-saving mode, after this loop, meaning almost 7 hours of continuous usage, the Xiaomi Mi 11 5G will go from 100% to 0% battery.
This proves that the Xiaomi Mi 11 5G's battery is robust; even under high intensity with light and heavy tasks, it maintains a relatively ideal duration.
For continuous gaming conditions,
Now, for the gaming enthusiasts with a desire for continuous gaming, can the Xiaomi Mi 11 5G last long enough? Battery tests for games like PUBG Mobile, Call of Duty, or Arena of Valor suggest an average gaming time ranging from 3-5 hours, depending on the game and in-game settings.

Conclusion
From the three battery test conditions above, it's clear that a premium smartphone priced over 16 million performs exceptionally well in battery life. Moreover, the Xiaomi Mi 11 5G is supported and equipped with 55W fast charging for ultra-fast charging; in just over 30 minutes, it reaches nearly 50%, and in a little over an hour, the device is fully charged.
If you're looking for a high-end device that justifies its price, especially with outstanding battery life, don't hesitate to grab yourself a Xiaomi Mi 11 5G.
