Detailed Evaluation of Sony Xperia XZ Battery Life - Exceeding 15 Hours with Mixed Usage
1. Detailed Review of Sony Xperia XZ Battery Life - Surpassing 15 Hours of Mixed Usage
The screen size isn't excessively large, and the specifications aren't overly powerful with only 3 GB of RAM, which might limit performance. However, the battery life of the Sony Xperia XZ is commendable. Equipped with a 2900mAh battery, in real-world tests, the device lasts for over 15 hours and 40 minutes of mixed usage, with over 6 hours of on-screen time and approximately 9 hours and 20 minutes of continuous video playback. During usage, the device maintains a relatively low temperature and only warms up slightly during continuous gaming.

Mixed usage lasted for 15 hours and 40 minutes, with on-screen time of 6 hours and 16 minutes
For users with high performance demands, the Xperia XZ may not fully meet their expectations, and Sony tends to be quite conservative as most high-end smartphones on the market today boast large screens, whereas the XZ features a 5.2-inch FullHD display. However, concerning battery life, these factors contribute to the device's ability to maintain prolonged operation, despite having only a 2900 mAh battery. Following the aforementioned test procedure, the results showed a mixed usage time of 15 hours and 40 minutes, with an on-screen time of 6 hours and 16 minutes.
To put it in perspective, imagine charging your Xperia XZ beforehand, at 7 am the device is fully charged, and you can use it until around 10:40 pm when the battery runs out. Additionally, usage time greatly depends on your usage habits; for example, if you frequently use your phone for gaming, it will undoubtedly drain the battery faster. Note that in this test, battery saving mode was not enabled when prompted. I believe if you activate battery saving mode, the device will operate even longer. Personally, I've used a Sony smartphone before and found the STAMINA battery saving mode to be quite effective, significantly extending the device's usage time.
The most impressive aspect of using the device is its smooth performance and lack of immediate heat buildup even during heavy tasks, such as continuous gaming.
Continuous video playback time reached 9 hours and 20 minutes
The screen offers excellent image quality, sharpness, and brightness, coupled with stereo speakers that enhance the movie-watching experience on the Xperia XZ. Although not as large as the speaker systems on the iPhone 7 or 7 Plus that I've used before, the XZ's speakers provide good sound quality, satisfying your entertainment needs. At 50% screen brightness and maintaining sound at this level, the device achieved continuous video playback time of 9 hours and 20 minutes. Using the included charger, it took 2 hours and 40 minutes to charge the Sony Xperia XZ from empty to full.
