We measured the battery life and device temperature of MSI's portable gaming PC 'Claw A1M'

Gaming PCs tend to have higher performance, but they also tend to have shorter battery life than business PCs. However, MSI's ' Claw A1M ' is a portable gaming PC that claims to 'enjoy a wide variety of games in full HD resolution anytime, anywhere,' and is said to be equipped with a large-capacity 53Whr battery, so we measured how long the battery lasted.

MSI's first portable gaming PC, the Claw A1M, is born!


With the default settings, when you start charging, the indicator next to the Thunderbort 4 port will light up and the analog stick and buttons will light up in seven colors.

After about 10 minutes of charging, the display, analog sticks, and buttons will turn off and only the indicator will light up red.

After another 5 minutes, the power indicator also went off, but it still wasn't fully charged.

First, I played Genshin Impact on battery power and used it to reduce the battery, then graphed the results. The vertical axis shows the remaining battery power, and the horizontal axis shows the elapsed time. Starting at 100%, the battery power was reduced at almost the same pace: 90% at 15 minutes, 80% at 30 minutes, and just over 60% at 60 minutes. After 120 minutes (2 hours) from the start of discharge, the battery power was 20.7%, and after 130 minutes, the battery power was reduced to below 15%, and the device's low battery warning message appeared. Measurements were stopped after 139 minutes, when the battery power was 7.1%.

On the other hand, the graph when charging while playing 'Genshin Impact' looks like this. The battery level recovers by 0.4% to 0.5% every minute, and after about 130 minutes, the recovery rate drops to about 0.1% to 0.2%, but then it returns to charging at the original pace, and the pace drops further from 97% battery remaining, taking 225 minutes (3 hours and 45 minutes) to complete charging.

In addition, when charging without playing games, the battery level recovered 1.0% to 1.5% every minute for about 15 minutes after starting charging. If you leave it like that, the screen will turn off and go into sleep mode, making it impossible to measure, so the overall measurement failed. However, since charging seems to occur at roughly the same pace, it seems safe to assume that it will take about an hour and a half to fully charge.

Next, we checked the heat issue, which is a particular concern for a portable device. When we applied a load using the load test execution software '

Passmark BurnInTest ', the front of the device reached a maximum temperature of about 41 degrees. We could see that the display and the buttons on the left side of the display were hot.

It seemed like heat was being dissipated through the small gaps around the buttons. However, since the fan is not actively dissipating heat, even when I placed my finger on the button, it just felt like my whole finger was warm, and no hot air was coming out.

Because the screen has a smooth surface, it may not be possible to accurately measure the temperature, so we also measured it with a non-contact infrared thermometer, which came out to 36.6°C.

Hot air is expelled from the top of the device. The internal temperature is about 56 degrees as far as we can see.

When I used a non-contact infrared thermometer to measure a position not directly exposed to hot air, it was about 40 degrees.

Looking at the back side, you can clearly see the location of the internal fan. The maximum temperature was 37.1 degrees at the top of the device, and the back side was not so hot.

The temperature inside around the fan seems to be about 46 degrees.

However, when measured with a non-contact infrared thermometer, it was about 30 degrees. When you hold the device, the air touches your fingertips, making them feel cool.

The AC adapter is about 48 degrees Celsius. It is obviously hot when it touches your skin, so be careful where you place it.

I used a sound level meter to measure how much noise the fan was making when it was operating under load, and it was about 55dB to 60dB. It's not much different from the fan noise you hear when using a regular gaming PC, so if you're using earphones or headphones while playing a game, the sound won't bother you.

My impression after trying out various software and games on it can be summed up in one word: 'A transforming gaming PC with Windows 11.' As it is, the only input is via a gamepad and software keyboard, making it difficult to use for anything other than gaming, but since it can be connected via Bluetooth, if you connect a mouse or keyboard, it can be used for business purposes as a PC with a slightly different appearance.

In terms of performance, the Intel Arc Graphics GPU may be a bit of a concern for a gaming PC, but as long as you set the game's graphics settings to standard to light, you won't notice any problems.

One of the few things that bothered me was the specifications of the charging indicator. It would be easy to understand if it was red when charging and green when fully charged, but perhaps because it is a Windows PC, the indicator would turn off halfway through the charging process, making it a bit frustrating not to know the charging status.

The MSI 'Claw A1M' is the 'Claw-A1M-002JP' with Intel Core Ultra 7 155H and 1TB storage, which we reviewed this time, and the 'Claw-A1M-003JP' with Intel Core Ultra 5 135H and 512GB storage is priced at 139,800 yen (tax included), and 99,799 yen (tax included).
