Imagine being able to use a laptop, or a phone, for days without plugging in. Can't do it with my laptop but my phone stays on for 1-2 weeks. That's the reason I have a very basic phone, and it does everything I want my phone to do. I would welcome a smartphone if it could do the same 1-2 weeks between charging. I could easily live with a "dumb phone" mode, that would just basically sleep while keeping 2G on for phon…

Xperia z (at least) series devices have an "ultra stamina" mode that does basically that. I have only tested it once, but it works really well and should give you way over a week of mostly sleeping. Source: I own a z1 compact.

Even my cheap Moto G will do something similar without having an "ultra stamina" mode. I've brought it to several hiking trips where it's been lying unused in a waterproof bag with everything turned off except basic GSM so I can receive calls and SMS. After 5 days the battery reports ~ 50% capacity and projects it will last for 4 more days.

Toyota already made a prototype solid-state last year. https://ecs.confex.com/ecs/imlb2014/webprogram/Paper33467.ht...

Battery prototypes are a dime a dozen, but none ever seem to reach the market.

Some do... http://www.extremetech.com/extreme/174477-at-long-last-new-l...

Is there an article on this which says something other than the same thing four times? Yes, I get they're replacing a liquid electrolyte with a solid one, but that's all this piece says. What electrolyte? Oh, and is it really infinite power as the article says? Of course not. Willing to wager this is just a breathless piece on carbon-air tech.

The lifetime refers to how many times you can charge and discharge the battery before it no longer works (if you have ever kept a rechargeable device for a long time you'll notice that the battery becomes less useful over time)

Wake me up when they have an actual reasonably priced working product in the market. This is getting tiresome as "breakthrough" news piled up but we are still using almost 10 year old technology.

R&D is not that simple and some of us appreciate this news. Coming to a thread only to complain that you can't have something immediately only adds to the overly negative feedback loop on HN.

Yeah! Is it all crap or is there something viable here?

I don't know much about battery tech but I get the feeling that "rut" is actually just their business model. Hard to sell a lot of batteries/phones/etc. that work forever.

I was just chatting to someone about this today. I feel like my "honeymoon" period with my new iphone 6 is coming to an end. 6 months in and I'm starting to have to think about when I charge it. Definitely it's not in Apple's interest to solve this particular problem, especially when (I think) they've deliberately made the battery non-replaceable.

You can take it to the apple store to get the battery replaced FWIW

His complain is not that he is not going to have it immediately, but that he is never going to have it. And I agree with him. We keep hearing of breakthroughs and the truth is that 99% of the time they vaporize.

That said, I'm happy to hear the amount of research put into finding better batteries.

It's always a possibility that we may never see this technology in use commercially, that does not mean that it is insignificant and cannot lead to an improved product later on. The work done here is still important regardless of whether or not we'll have it in our hands within the next five years.
