Asus Transformer Book T100HA Review - Battery, Sound and Camera Review


Asus Transformer Book T100HA – Battery

The Transformer Book T100HA is powered by a single 30Wh, non-removable battery. I’m a little sad Asus hasn’t loaded the attachable keyboard with a secondary battery, though Asus’ projected 12 hours video playback life is, on paper, impressive.

However, with general use the Transformer Book T100HA fell short of that projected 12 hours. Using it as my main laptop and tablet I generally got 7-10 hours’ use out of the Transformer Book T100HA.

General use entailed typing a few news articles, sporadically browsing the internet, regularly checking my email and social media feeds, watching an hour or two of Netflix, and playing the odd round of Xcom.

When streaming video I found the Transformer Book T100HA discharged a little faster, usually losing 15-20% of its charge per hour. Gaming also put a hefty drain on the battery. Playing a variety of titles including Xcom, Pillars of Eternity and The Escapists, the Transformer Book T100HA lost 20-25% per hour.

Asus Transformer Book T100HA – Camera and Sound

I’m yet to find a tablet that’s good at taking photos or shooting video. The Transformer Book T100HA continues this streak.

Loaded with 5-megapixel rear and 2-megapixel front cameras the Transformer Book T100HA is pretty bad at taking photos or recording video, even by tablet standards.

Images taken on the tablet section universally look slightly washed out and aren’t as sharp as I’d like. The rear camera is also all but useless in low light. Video is also fairly grainy and in general I’d recommend you avoid using the rear camera unless you absolutely have to.

Being fair to Asus, this is an issue I’ve seen on most Windows 10 tablets and convertibles. The 2-megapixel camera proved more than good enough for video calls on Skype and Google Hangouts.

The Transformer Book T100HA’s speakers proved equally poor. As well as having a woefully low maximum volume, sound quality is fairly poor. The speakers’ low end is close to non-existent and sound coming out of the Transformer Book T100HA has an underpowered, nasal quality.

Should I buy the Asus Transformer Book T100HA?

For £299.99, the Transformer Book T100HA offers reasonable performance, decent battery life and all the perks of Microsoft’s latest Windows 10 operating system.

However, it’s design does border on being dull and I’m a little disappointed with its display’s 1280 x 800 resolution.

But even with these issues, the Transformer Book T100HA is a solid choice for any buyer looking for an affordable Windows 10 convertible.


The Asus Transformer Book T100HA is a solid, but slightly dull, pint-sized Windows 10 convertible.
