New Year Countdown Series: #5

Filed under: Design guidelines — Tags: , , , — Andrew Zhilin @ 15:04

Merry Crhristmas to all my readers! Hope you’re enjoying that day and Santa have a small present for you – one more improvement. But now it’s not UI modification – it’s way cooler and super-handy! Check it out after the break.

Today I’ll show you significant hardware improvement that will dramaticaly improve user experience.
One of great n*** series feature is swapable battery. It allows you to take backup batteries with you to long trip and you’ll be always online. Ofcourse, first goal would be to increase battery capacity or lower device’s power consumption, but I have another sollution.
What if you can swap the battery without turning off the device. You’ll no longer need to re-open dozen of browser windows, several e-mails and some IM sessions. No more reconnections and other stuff. All you need to have is a small “pill-size” battery inside the device, to give user several minutes to swap main battery. And you no longer need to switch the device off!


That’s all for now, happy holidays and see you tomorrow, I have more cool stuff to show you!



  1. This will be a very welcome addition to the tablets. It’s been talked about in the forums, and hopefully someone at Nokia/Maemo will think it’s a useful feature to have. There are limits to battery capacity, especially in the form factor required by our devices. A hot-swappable battery would change the game for many. Thanks for this blog post!

  2. One thing you could consider in that instance is simple hibernation too.. suspend to mmc, maybe?

  3. Hybernation is good way, but you’ll still lose connection. Hotswap is more… hot)

  4. supercool! Thats a nice feature to push for.
    All we need now is a quick release for the battery, so we can pop the old one out like a used ammo clip!

  5. Very cool and useful feature. Psions had backup batteries 10 years ago, as the main batteries were std AA size, so replaceable aynywhere.

  6. Its a nice idea. Even if you could just plug it in the power port to run temporarily while the switch was being made, with the understanding that it is temporary. Alas, no one will invent this, there’s not even an external charger (a dock) for the batteries.

    They put their time and money into the next big gadget.

  7. +1

    this is an awesome idea that would be a great addition both with the tablet and in the nokia cellphones. personally I rarely run my phone battery dry, but I know lots of people that carry spare batteries. It would also be an amazing feature for cell users if they could pop and replace mid-call.
