Asus Eee Pad Transformer TF101: A Tablet In Disguise

Battery Life And Recharge Time

Battery Life

Testing a tablet’s battery life tends to be highly variable unless you control the entire experience, from beginning to end. Cumulatively, touch gestures don’t have a great impact on battery life. The biggest factors are CPU/GPU processing, screen brightness, volume, and Wi-Fi use.

In order to accurately measure battery life, I coded a script that automatically plays MP3s at 50% volume while browsing different Wikipedia pages every 12 minutes. This benchmark is probably overkill, but it gives you an idea of a worst-case scenario.

Recharge Time

Charging times are a double-edged sword. Ideally, you want a nice slow charge so that your battery lasts more than a few hundred cycles. Fast charge times get you away from the wall wart more quickly. But, in the long run, they cut down on the health of the battery. Usually, the rate of charge starts to slow down somewhere in the 80% to 95% range, which is why the charging time from 0% to 10% is faster than 90% to 100%.

    Having recently tried the Transformer in person, I can say that it doesn't feel cheap and the novelty of the docking system could be awesome in future iterations. But as I recently found out with my $99 HP TouchPad, tablets have a long way to go in some areas. In the TouchPad's case, many of it's problems seem to go away when overclocking it's processor from 1.2Ghz to 1.8Ghz +. Of course, it's battery life is already less than compelling so you don't really notice the higher power usage. Like so much in life, better and faster hardware makes all the difference. Higher clock speed overcomes many of the problems HP could have ironed out had they given WebOS more time.

    The Transformer is a not-insignificant step forward for Android tablets. As an optimist, I believe the next iteration will be pretty damn good. But like the TouchPad, who knows how much longer it's going to be around?

    Yeah, if you are American. Hey Toms, how about you find some way to only display the comp if the reader is on an American IP address.
    Or better yet, find a way to let us enter.

    What is the point of a 32gb model when the tablets has a micro sd slot? I can get 2 32gb mSD cards for the extra $100 bucks.

    I went to the verizon store to get help choosing some decent headphones for my bionic. While I waited for him to go in the back of the store and get a few models, I started playing pinball on the galaxy tab 10.1. When he came back there was that brief moment I couldn't decide to keep playing and ignore him, or set it down. win win here.

    They could do international possibly, if any international persons agreed to help pay shipping (I bet). A UK site I won't name allows international entries and lets them know up front they'd try to work with you on the shipping costs, etc.

    Wanted to add. I bought a transformer and dock for my mother. She's in her 60s and loves it. She takes it to work, to the coffee shop. I set it up for her, my first time with Android, and it definitely has its uses.

    Well the first thing I think of when I'm looking at a tablet is NOT watching a movie in the park or playing around like most commercials show. I actually think of when I get up off the computer chair to head to the toilet. I don't read the newspaper here so where else am I gonna get my up to date info? Only bad thing I can think of for that is needing to wash hands and Tablet. :P

    On the other side of the screen argument it seems to be one of the few that does not need closed curtains.
    Heavens forbid, it sounds decent outdoors too thoug OLED is probably better.
