Battery Life Testing

Battery life on the KIN was a shocker. It was superb.

Both of the KIN not only delivered above average call times of around 6 hours, but also 3G web browsing times of around 7. But the real shocker was WiFi web browsing battery life, which came in at around 13.5 hours. I ran this test twice on both phones because I was confused. It really lasts that long.

As a quick reminder, our web browsing benchmark loads a set of nearly two dozen webpages, pauses for 20 seconds on each one, and then loads the next page. None of the pages use flash, and the set loads endlessly until the phone's battery is exhausted. Screen brightness is set to 50%, and configured to remain on the whole time. Testing over WiFi is done in the same room as the AP.

For call time testing, we play music on repeat into the microphone of the phone and call another phone, also playing music into it. This simulates voice transmitted and received. The displays are also allowed to go to sleep as they would when used in a normal call.

The result of all this testing is the obvious conclusion that the KINs have incredible battery life. In fact, the WiFi battery life on these devices was nothing short of amazing. It's entirely possible that Sharp aggressively underclocked the NVIDIA Tegra APX 2600 to get these numbers, or that there's other throttling going on when the device is idle. We don't measure standby time yet, but whereas my HTC Incredible would be dead within 24 hours of being unplugged, the KINs would last multiple days in standby.

Performance in the browser wasn't stellar, but pinch zooming and other multitouch gestures felt snappy. At other times, the browser and UI would really feel choppy while scrolling. It was a mixed bag. One thing was for certain however, the JavaScript engine on the KIN browser was abysmally slow, so even though the browser felt decently fast for most browsing, the JavaScript heavy tests we run on smartphones gave very poor results.

    One thing people seem to forget (too...), is the constant sync on android devices with your google services (mails, talk,...), along for most devices with a sync with facebook, flickr and twitter. The iPhone doesn't come close to that (even with the last iOS4), and WM is a laugh in that perspective. Deactivate those syncing (or slow them down), and android devices last much longer, easily one day and a half for my legend.

    The Motorola Devour had that Sidekick form factor as well, really liked it quite a bit.

    I had it for about a month and a half...the keyboard on it, the general build quality, most everything about it was phenomenal, except for:

    the shitty camera--3MP supposedly, no flash, no auto-focus, just crap.
    lousy reception--the reason I traded it in for a Droid

    of course it still hasn't been rooted (or updated past 1.6) so that's pretty disappointing as well. And it looks like Motorola is hellbent on locking down their new phones to completely take the mod/hack/customizing communities out of play.

    The metal case and internal antenna really hurt the Devour. Running a slow chip and old Android OS didn't help either.

    Android has captured the market for "open" phones (i.e.: open app store, etc.). Apple has the fanboy and zealot market cornered. I can't see very many people choosing WP7 over either of those two.

    The arstechnica article from a week or two ago is far better on the topic. This article is written from a fanboy perspective and ignores reality completely. The reality of MS essentially killing Danger after buying them for a few hundred million.

    I had the same feeling. This article is missing a lot of details, which isn't the norm for this site.

    What, a fanboi of a disappearing OS? I personally didn't feel all the internal microsoft bickering had to be included here (it is documented elsewhere) and instead this article was written from a perspective of "Is there anything positive to pull out of this?" And I thought it did that well instead of focusing on the specifics of the phones as not many will be buying them anyway.

    So an article about the phone and its features, pros, and cons, but sans-drama is fanboyish? Ars always finds a way to inject drama. All their self-righteous treaties on the ethics of video game reviews, and such.

    The article is titled 'a eulogy'. If you want the TMZ version - stick with Ars.

    WinMo really does take all those points, and put them in a more business approached user interface, while taking notes from classic IT user requirements.

    My TyTn II definitely does everything the KIN, iOS, WebOS, and android phones can, just it's been able to since before them...

    Now I can't say it has the flare, GUI or app style. The Microsoft app store is the worst software I ever thought to install. The graphics are something HTC has been holding back forever. Otherwise functionality speaking, I can do anything you can do, just it may take me a day to figure it out.

    What it comes down to is what YOU do. I read about 75 RSS feeds daily(long commute.) I also listen to Pandora the whole time. Meanwhile between my feed reader, the browser or browsers I may be running, Pandora, and typically word/excel/foxit, I still make it 5-8 hours constant usage(which translates into a day adding in time I actually have to do stuff IRL) oh and Wifi is on for at least three of those hours.

    I upload pictures directly after taking them via email, which is one click from the after-shot menu. Facebook conveniently is on my homescreen(I don't use the other sites so much) as well as my favorite feature, contacts stay as is, until I open them click, the Facebook link, and from the UI I can pick any info I want synced.

    Wifi syncing on Activesuck, works(only because there isn't any good open source alternative.) and Google sync keeps my online calendar up to date with stuff I have to do, as well as backs up my contacts. Since I don't text(yea smartphone user so long I've replaced SMS with POP...)backing up messages is my gmail. Plus my backup for microSD is Wifi at home(yea networking try that iOS and android playaz) When I connect to my network, bam my SD is ghosted(as real files) and sync occurs with my file server.

    I like the KIN's web app. I really hope that transfers into the WP7 features. Danger definitely had something going for them, hope M$ uses a few hint from there world. The Dell mini 5 is on my next list, but the HD2 is my very next.

    I would have to agree to a certain point. I have a LG Incite, Winmo 6.1. I havent seen enough from Android or iOS to switch yet. Ive been multi-tasking for well over a year, can go 2 days without charging with moderate use. I can VPN to my home network via Hamachi, use remote desktop to connect to any computer on the network.
    Have had SPB Mobile Shell since 3.0.1, recently updated to 3.5.5 - great features, totally customizable UI.
    WinMo was really great for the IT/professional aspect, but not so great for the average consumer aspect - which is where the money is.
    Although I have AT&T, that HD2 is next on my list as well, as soon as my contract is up (shortly).
    As for the KIN, they were aiming for a demographic already covered. Im surprised someone OK'd the release.
