Battery Life

The Transformer Book T100 features an integrated 31Wh battery. As the keyboard dock doesn’t include an extra battery, that’s all you get. The good news is that Intel’s Atom Z3740 is built on the company’s first 22nm SoC process and it’s paired with LPDDR3. At least on the silicon front, the T100 should be fairly power efficient. Granted there are still the PMIC, display, WiFi and other components to worry about, but here’s to hoping ASUS did a reasonable job there as well.

Unfortunately ASUS delivered our T100 review sample less than 48 hours ago and I’ve been using it non-stop since then. I think I technically broke embargo by using it at a press event but it’s the only way I’d get enough time with the thing under my belt to feel comfortable writing about it. The bad news is that I only had enough time to provide a battery life teaser. I’m still running more data but for now all I’ve got is our WiFi web browsing test.

The T100’s results are presented with the keyboard dock attached and with the display calibrated to 200 nits:

Web Browsing Battery Life (WiFi)

Battery life looks decent at just over 8.5 hours on a single charge. In practice I had no complaints about battery life while using the device. It feels more like a tablet in that regard and less like a notebook, which is a good thing. Once again we’re seeing ASUS redefining what we’ve come to expect from an entry level notebook PC here. Even compared to Chromebooks we see the T100 do extremely well. I’m curious to get a better feel for how Bay Trail performs in the battery life department, which I’ll be doing over the coming days. So far the results look good but not quite stellar if you compare it to traditional Android/iOS tablets. I am curious to see how BT running Android would turn out.

    Or they could have released it at $360, and taken that extra 10 dollars to add the top of the line baytrail and 4GB of ram.....

    It's just ugh......

    I'm curious to what extent the last few dollars corner cutting $350 price tag was influenced by their experience with the Vivo models last year. That hybrid AFAIK was $400 with the last gen Atom, and sold quite poor. Reply

    Was not impressed with the battery life and keyboard. I might wait for the Dell Venue 11 Pro or maybe I would add more to my budget and go for the Lenovo YOGA 11 2. Reply

    How is battery life is bad when it lasts nearly the same as ipad mini and better than nexus 10 and other galaxy tabs?

    Remember, the battery test was done with keyboard attached which is not the case for other tablets.

    I agree, plus the keyboard in this case does not have any additional battery in it like the Acer W510 keyboard that adds another 9 hrs of battery life, but heavy. This device as tested yielded 11 hrs. That is very good battery life. Reply

    ignore these people. They never buy much, just talk a lot. Reply

    11 hours of battery life is not impressive? I take it the Lenovo Yoga 11.2 last for 2 days Reply

    what about a comparison with the a6-1450 temash? Reply

    AMD didn't given Anandtech a platform with a6-1450 on it. So they couldn't test it. Reply

    I had the T100 preordered but canceled to wait for the new Venue 8 and venue 11. I do not know which will be better but hopefully they will review them here to decide Reply
