Samsung Galaxy Tab 10.1: A Second-Gen Android Tablet

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 keep you away from the wall socket longer, 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%.

This is the Galaxy Tab 10.1's Achilles' heel. If the battery is completely drained, it almost takes a quarter of a day to get it fully charged again. That could be a problem for more hurried road warriors.

    No surprises here, iPad 2 is still on top, being the engineering masterpiece that it is. Take a look at side-by-side comparisons of iPad 2 and Galaxy Tab 10.1 on YouTube and you'll see how much smoother animations and video recording are on the iPad 2.

    I'm going to be in the market to buy about 150 tablets soon and from this article it appears that the ASUS 3.2 is the best all around for price/performance/recharge. While it doesn't win alot, it appears to be a consistant performer and has a relativly short recharge time.

    Or am I missing something here?

    The reason why Samsung doesn't want to lower it's price is easy to understand: there are many (stupid) persons who are convinced that the iPad is superior to any other tablet just because it's priced higher... Samsung wants to make sure they capture that part of the market.
    But the author is right: if there is one reason Apple should sue Samsung, it's for copying the price structure of the iPad!

    Samsung Galaxy Tab needs a split keyboard feature in portrait mode; it isn't comfortable enough to have to stretch to hit the virtual keys.

    The 10.1 is still too slow for certain browsing. Flash is good as long as you don't want to rewind or fast forward through it. It sometimes slows down when I try typing also.

    Since Apple produces both hardware and software, they can optimize their OS for the exact hardware they put out.

    After trying the Samsung Galaxy Tab 10.1, I would say it's just a little too immature still. A good year or two and tablets will be perfect for browsing, gaming, and some other tasks while also being lightweight and easy to use even compared to laptops.

  • Hmmm, many talk about iPad dominance but don't know all the facts. Just looking at a device in the store doesn't cut it folks. Android tablets are going to start cutting into market share, like it or not. For an IT person or true techie, most would choose an Android tablet. 4 core coming soon and they are going to rock the scene. Example: my Acer Iconia costs quite a bit less than iPad2.
    -Full USB port for mouse, keyboard, portable hard disks/thumb drives, cameras
    -Overclocked and stable dual core CPU @ 1.504 Ghz (big change in performance)
    -Customizable and open operating system (and it's going to get better with ICS)
    -Honeycomb 3.2
    -Netflix and Hulu working
    -Mount drives from Linux, Windows, and OSX
    -Websites with Flash that look the same as on a PC browser (now theres a concept)
    -Wide screen 16:9
    -5MP rear camera + front facing camera.
    -HDMI out
    -Charges back up in 1hr

    Price, proprietary cable management, and lack of expandable storage all lead me to want to wait to see what happens after Windows 8 becomes available.
