I checked the battery performance of the Copilot+ PC 'Dell XPS 13 9345' equipped with Snapdragon X Elite
Dell's thin laptop ' XPS 13 9345 ' meets the requirements of Copilot+ PC, and is equipped with Qualcomm's Snapdragon X Elite, known for its low power consumption. We measured the battery life in multiple patterns.

To measure the battery life, we performed two patterns: 'continuously watching YouTube' as a light load for everyday use, and 'continuously playing FFXV Bench (high quality, 4K) in a loop' as a heavy load. Originally, we wanted to use online games such as 'Genshin Impact' that require an internet connection as the heavy load, but we gave up because we could not start 'Genshin Impact' on the XPS 13 9345.
The PC settings were set to 'Maximum Performance', with the screen brightness at maximum and the volume at 10.
In the graph below, the red line on the left shows the high load state, and the green line on the right shows the light load state. The vertical axis shows the remaining battery power, and the horizontal axis shows the elapsed time in 5-minute increments. Under high load conditions, it took 135 minutes (2 hours and 15 minutes) to reach 6% remaining. Under light load conditions, it took 560 minutes (9 hours and 20 minutes) to reach 2% remaining. Even though I was just streaming YouTube, it's a pretty good battery life to run for more than 9 hours, and the fact that you can extend the operating time even further by lowering the screen brightness seems convenient for business trips.
Below are the charging speeds measured under similar loads. The green line on the left is for a light load, which recovered from 6% to 100% in 135 minutes (2 hours and 15 minutes). The red line on the right is for a high load, which recovered from 6% to 100% in 180 minutes (3 hours). This is a speed that is expected from a device that supports Power Delivery. Although no special settings were made for 'gentle charging,' the battery stalled at around 99% for the last 30 minutes or so under high load.
I used
While some parts were approaching 50 degrees, there seemed to be fans located just behind the left and right sides of the keyboard, and the temperature was below 30 degrees.
There is a slight difference in temperature between the palm rest and the touchpad.
Looking at the device from the side, hot air of about 50 degrees was coming out towards the rear.
The part closest to the terminal is over 50 degrees.
Also, when I lifted the device and looked at the bottom, it was hot all over, and the back was closer to 50 degrees. It's best to avoid working with it directly on your lap.
It is important to note that the AC adapter became very hot, reaching nearly 70 degrees Celsius. It is best to place the AC adapter in an open area, such as on a desk, and keep the area around it clear.
We also measured the fan noise under high load conditions with the digital sound level meter
When measured from the rear, it was about 56dBA. As expected, since that's the direction the exhaust comes out, the sound is quite audible, but it's within the normal range of operating noise for a laptop, and it's not noticeable when working in a cafe, for example.
I carried it around from place to place and tried moving it around in various ways, and as it is a 13-inch PC, it fits into a relatively small bag, and because it is thin it doesn't get in the way, and the weight isn't an issue, so I felt that it was the perfect size and weight for what I would like a laptop to be.
The battery life is long enough, which is important when using it in an environment where it is not always connected to a power source, and the charging speed is fast, so it is appreciated that the battery life can be extended by simply charging it briefly.
However, since this is not a gaming PC, it can't be helped, but I was a bit concerned that it couldn't run graphic-intensive games or benchmarks.
Also, although it's a matter of preference, I often have to press function keys such as F2 and F4, so I would have preferred physical keys rather than a flat panel key that requires me to visually check their location.
The XPS 13 9345 configuration used in the review can be purchased for 252,421 yen from Dell's official online store. Prices vary greatly depending on the configuration due to various discounts, for example, a configuration with 16GB of memory and 512GB of storage costs 227,436 yen, and a configuration with 64GB of memory and 2TB of storage costs 315,315 yen.
