Battery Life

Gear’s designers went in a direction that completely defies most of the norm we’ve seen in this latest crop of smartwatches. Rather than the low power Cortex M3 route that seems to be popular, Samsung went with a dual core SoC (Exynos 4212), disabled a core, and set the CPU frequency to a maximum of 800 MHz. On top of the whole thing runs Android 4.2.2 and the Gear software, making the watch more like a small smartphone. The combination of aggressive display timeout (with a maximum of 5 minutes) and the activation gesture for waking the watch up signals to me that battery life probably was a challenge on the Gear.

I don’t really know what the best way is to battery life test a watch yet, and I struggled with that while trying to review Pebble. I settled on just timing how long I got through a battery charge there, which ended up being almost exactly a week (7.02 days was my average), which is basically my only context for what smartwatch battery life should be. The Gear obviously has a considerably more powerful platform, display, and capabilities, so it isn’t a shocker that battery life overall is less.

It’s easy to get around the display timeout limitations and just keep the display on Gear turned on forever, displaying the watchface. I ran a rundown test with the watchface set to brightness level 4 (there are levels 1–5 and outdoor brightness) while connected over Bluetooth to the Note 3. Gear managed 5.117 hours of total screen-on time showing the watch face (clock plus weather) connected to Note 3.

Of course the way that Gear is setup which prevents display from being on all the time, battery life during actual use will be longer. I’d say somewhere just over a day would be on the short side, maybe two or three days is possible if you try to stretch it a lot. I placed a few calls and played with Gear a lot one day and almost didn’t make it through, another day I felt like Gear would’ve lasted two had I let the use pattern continue.

The positive side is that thanks to its smaller battery, Gear can charge from completely drained to 100 percent in just under an hour, the simultaneous downside is that you need the charging cradle to do it. If you’re comfortable charging the Gear daily, it’s survivable, the question is whether consumers are willing to adopt the daily charge requirements of another device. I’ve gotten in the habit of plugging Pebble in every night, so this isn’t a big deal for me, but I also enjoy having a week of battery life when I go travel. I suspect that’s a use pattern that others can empathize with when considering Gear, which guarantees a little over a day of use realistically, and a bit more if you’re careful.

    Transparent display... a normal watch underneath...
    Notifications appear on top of the watch waking up the display when needed.. otherwise it remains a humble normal transparent glass..
    A stripped down OS suitable for wearable..
    How long? How difficult?
    Seriously though, can transparent displays be a reality?

    Just like when tablets appeared a few years ago: I have to stop and ask: for which use case is this thing in any way useful? Using voice recog is slower than typing, (especially in noisy conditions like anywhere outside your own house or car) it can't be comfortable reading anything from a device attached to your wrist, because you'd have to keep your arm up or your neck bent, and it'll be slower than the phones we spent years and billions making oh so blazing fast.

    This is to a smartphone what a tablet is to a laptop: smaller and more portable, but limited in functionality and speed. Sure, a tablet is easier to use on the go, but on a laptop you can get some work done.

    It must just be our neverending consumerism. Phone market becomes saturated, and all those billions of marketing budget are spent brainwashing people into thinking this is something they need.

    I'd seriously like to see one, just one, proper use case for this little machine. I cant think of a situation where pulling my phone out of my pocket wouldnt be faster and easier.

    There's just one problem with your argument.

    Tablets kicked out e-readers and netbooks, because most people just wanted something that will do facetube, movies, light games, email and internet and cost less than $400.
    Some experienced users may want to use office, and that too has been covered quite well by both cheaper ARM devices and more expensive ultrabook convertibles.

    So, going by your argument, you are actually making a case for the watch, it's just that we're not quite sure what other products it's going to kick to the curb as of now, just like what happened when tablets first came out.

    The way I see it, the only thing this watch might kill is HUD and handset holders inside cars.

    Tablets haven't kicked out e-readers, at all. E-readers are still better at reading most things than tablets.

    Netbooks, on the other hand, are worse at everything.

    Totaly agree Fergy. It seems the Apple trolls are out in force and must have received talking points about how applelish the watch looks. Not realizing that Apple has been stealing from others much longer than they've been alive! Apple has not met an inovation that they themselves have either stolen, borrowed or copied from!

    How are you apple trolls liking your IOS7 now! I hear and read how smoothly things are going...not...lol

    Apple will claim anything is their innovation just to stall the other company from getting their goods to the public! Remember the lawsuits over color and shape of the iphone? Like no one would think of a square phone with buttons? Like they owned the pattent on shapes like a rectangle or circles? Please, from the beginings Apple and Microsoft were perfecting the ways of stealing from each other in order to later do the same to other companies.

    You mention using the Pebble regularly in your review of this product, but I don't see that there was ever a review of the Pebble. I would be interested to see a review, especially to give this review some context. I just tried to search for "pebble", so it's possible that it just didn't come up in the search.

    I suppose Samsung made an effort design wise here, but it's still very ugly.

    So, how does it feel/look when worn properly, aka with the face on the flat part of your wrist (the bottom)?
