Japanese electronics company Fujitsu has a history of making ridiculously lightweight laptops, but the new Fujitsu LifeBook UH-X/E3 takes things to extreme.

It’s a notebook with a 13.3 inch full HD display, an Intel Tiger Lake processor with Intel Xe graphics and full-sized Ethernet and HDMI ports. But the laptop measures just 0.61 inches thick and weighs just 1.4 pounds.

Of course, something’s got to give, and in this case it’s the battery.

The Fujitsu LifeBook UH-X/E3 has a 25Wh lithium-ion battery, which is pretty anemic by modern standards. Fujitsu says you can expect up to 11 hours of battery life under ideal conditions, but I suspect you should probably cut that number in half in real-world conditions.

The RAM is also soldered to the motherboard and there’s no way to upgrade it.

Fujitsu does offer a similar laptop called the LifeBook UH90/E3 with a 50W battery, but that model has a starting weight of 1.8 pounds.

Here are some of the key specs for the lighter UH-X/E3:

  1. Do you know if/when they will release it to the global market? I saw that their own domestic release dates were already pushed back to end November.

  2. The numbers don’t stack up…ultra books can generally idle at ~5 watts. Unless TL has significantly improved on this 11 hours isn’t going to happen. So 25Wh / 5Wh = 5 hours use at idle or watching local video. For more typical office work you are going to get 2.5 hours or I’d say about 1 hour of gaming or other heavy load activity.

    1. I think a 5W draw might be too high for recent laptops. I know these benchmarks have limited relevance to real life, but it at least illustrates that newer laptops can sometimes drop down to the ~2.xW range with nondemanding usage:
      61Whrs / 30.5 hrs = ~2.0 W draw – https://arstechnica.com/gadgets/2019/03/guidemaster-the-best-windows-ultrabooks-you-can-buy-right-now/2/#h5
      52Whr/21:27 = ~2.4W draw – https://sea.pcmag.com/netbooks-products/35965/dell-inspiron-14-7000-7490
      66Whr/30:36 = ~2.2 W draw – https://sea.pcmag.com/laptops/36198/asus-expertbook-b9450

      For all Intel’s flaws, their new push for power efficiency (including the screens) is paying dividends.

  3. That battery is unfortunately anaemic: if they beefed it up another ~15Whrs, they’d still probably be able to keep the weight under 750g, and 40Whrs would actually be useable…

    But, more interesting was that they could get full-height arrow keys in there – quite difficult to find in more recent laptops!

  4. Now that Xiaomi charger pads can support 80W fast charging, why not sell similar tech charger pads with small battery laptops?

  5. I’m pretty okay with my thinkpad L440’s 3-4 hour battery life. I’m sure I could make do with this if I had to. Unless Consumerist zealots will disparage people seen in public with a plugged in laptop.
    (also you probably meant watt-hours).
