We all know that sometimes some things don’t come as advertised. Some products and advertisements may offer you the world but you’ll soon find that it’s only ‘seen on tv’ and it’s not the same when you actually see it in real life.

After I had posted a review of the Toshiba Portege Z830 Ultrabook, many of you had asked me how long can its battery last, so today I decided to put the Z830 Ultrabook to the test by using it on a single full battery charge and see how it will perform under Ask Aaron Lee’s scrutiny and how it will compliment my work.

Part of my job involves me reading and keeping up with the latest trends. Opening a ‘million’ tabs at once becomes the norm because I need to know what’s happening in social media, as well as having other programs opened for writing and sharing some of the best tips that I’ve learned from my own personal experience.

Then there are times where you simply cannot write but at the same time your blog post isn’t quite ready to be published, so I need to open even more tabs to watch a lot of funny baby videos on Youtube to reduce stress levels. *cough cough*

Having said all that, today’s blog angle will focus on the battery of the Toshiba Portege Z830 Ultrabook and the amount of work I am able to get done by using a single full battery charge.

The tests are pretty simple. We’ll see how many posts I can read and write, and compare the performance of the battery according to Toshiba’s advertised 8 hours of battery power life. The question is, can the Toshiba Portege Z830 Ultrabook keep up with someone like ME?

According to the battery life (on Power Saver) when I started a couple of minutes ago, the Toshiba Portege Z830 Ultrabook had a 97% battery life which translates to 7 hours and 13 minutes lifespan. I must say that I am impressed with its battery as it is a product that is only 15.9mm thin and weighs 1.12kg!

How thin is it exactly? Here is an illustration by a fellow Toshiba Portege Z830 Ultrabook influencer Beatrice Tan who took a photo and shared it on her blog comparing the thickness of an iPhone and the Z830 Ultrabook.


This tiny little thing definitely packs a punch. Just like me, except that I am much much much heavier and ‘thicker’.

Like me, the Toshiba Portege Z830 Ultrabook is also equipped with great personality.

This Z830 Ultrabook comes with:

  • SD card slots
  • 3 USB ports
  • Headphone and microphone jack
  • VGA port
  • HDMI port (to connect your laptop to your tv, etc)
  • ethernet port (to connect to your internet via cable, etc) which at the moment, a Macbook Air doesn’t have.

Coming back to our little test, here is the sum-up of today’s worth of work:

Battery life before work officially started:

  • 7 hours, 13 minutes
  • 97% Remaining
  • Time: 11:45am

Battery life during my Youtube-time:

  • 4 hours, 20 minutes
  • 57% Remaining
  • Time: 2:38pm

Results until the battery power went off:

  • Blog posts written and completed:  4
  • Blog post still in draft mode (Partially done, 10%-50%):  3
  • Blog post read/skimmed: Too many. I lost count after the second hour.
  • Number of comment left on blogs: 5
  • Cups of coffee drank: 2 cups
  • Time: 6:54pm

Battery life: 7 hours, 9 minutes

The long battery life of the Toshiba Portege Z830 can also be attributed by the core processor by Intel, which has a high performance and energy efficiency.

Essentially this line of processor that Intel came out with helps to reduce the power comsuption but still delivers in performance.

The Z830 Ultrabook did go to Sleep Mode twice as I went to grab lunch for awhile and took a short break. Therefore, the time varies for different people and different uses. With over 7 hours of battery life, this little thing does pack itself with some power.

Furthermore I fully believe that the battery life would reach the advertised promise of 8 hours as I am generally very bad at Maths and therefore would’ve botched the timeline anyway. At the end of the day, my impression of this Ultrabook still stands. For a lightweight and thin Ultrabook, the Toshiba Portege Z830 Ultrabook is definitely worth taking a look.

    I’ve had this laptop for a few months now. It does have really good battery life. But a couple of times, I’ve noticed that when the battery gets below 25% or so, my wireless connection starts cutting out. Websites take longer to load, sometimes not loading at all. But as soon as I connect the A/C cord, the connection goes right back to normal. Have you ever seen that?
