Future of long-lasting batteries

[omega3]

Anybody knows which technology will finally give us batteries that last longer than 1-2 days of use?

 

[Yuriman]

Yes - thicker phones.

 

[omega3]

Yes - thicker phones.

I wouldn't mind a thicker phone.. my question was about which battery technology in the making will finally give us usage of a week or more.

A week or more without charging, and you are using it? Maybe sometime by 2030 you will see that.

There is no battery tech out there that can do that for the foreseeable future.

2030? Siriously? By 2025, I am expecting CPU's to draw only half the power required today, with a boost of 5 times faster. Also Display screens will require less power to operate. So, even if your 4000 ~ 8000 MaH battery could give you 3-4 days on the old battery technology with smaller fabs and dies required a lot less power you could go 5-6 days easily.

That being said, there is TONS of new battery tech that is pushing the market... like this one...

Recently, a team of researchers at the Samsung Advanced Institute of Technology (SAIT) developed a “graphene* ball,” a unique battery material that enables a 45% increase in capacity, and five times faster charging speeds than standard lithium-ion batteries. The breakthrough provides promise for the next generation secondary battery market, particularly related to mobile devices and electric vehicles. In its research, SAIT collaborated closely with Samsung SDI as well as a team from Seoul National University’s School of Chemical and Biological Engineering.

Faster Charging time as well as almost 50% increase in capacity. Maybe the S9 will have these installed as I've heard the Note 8 is already using this tech. So, now your thin 5000mah just become a 10000mah battery. That alone could probably give some people a weeks worth of usage...

Take a look at this...

I think it won't be long till we get some sort of solid state hybrid battery that will be able to charge in seconds, offer 50% more power density and can be recharged for thousands of cycles.... Probably in 3-5 years something will come to fruit.

Yes - thicker phones.

Also, you can get what you want if manufacturers put low-end hardware with batteries high end phones use. Makes perfect sense doesn't it? Batteries used to last for days on phones, before Smartphones.

All of that would be great - if the phone manufacturers would retain the same battery size. But they likely won't. They'll make the phones even thinner, with smaller batteries. Thin sells. But I hope that consumers will eventually recognize that thinner isn't always better.

Why haven't they made solar panel screens yet? That would be good for topping off the battery while in use.

Lol yeah let's make the screen as dark and opaque as possible to absorb the most light.

 

[mindless1]

We already have that tech. People wanted smaller, faster, fancier phones instead. That's the way it's going to stay, keep getting smaller (thinner), faster, fancier. .

Solar panel could go on the back, but either way you have to keep the thing pointed at the sun.

I used to want longer battery life, did have a fairly thick phone, then I got a 5.5", then downsized to 5.0" phone. For my uses, a phone that size with a thick battery is just too heavy. Maybe if I carried a purse or tried to do *everything* with a phone.

I just need a day of runtime, can make it a routine then, to recharge the phone while I recharge (sleep). On special occasions I have a portable power pack or car charger.

There ya go. That's why there aren't thicker phones with bigger batteries. People like what they have. Its quite funny, because they get thinner so you have to get even more robust protection on your phone, raising the thickness back up. But they get even more cash from you because you have to buy the protectors. My Motorola Moto E is thick enough and has good enough grip that I don't have to use a protector if I am not too careless.

Solar panels are extremely expensive for the power they provide. If they want to have it as part of the screen, its possible, but the efficiency would be so low it would not be worth it. Even the back panel ones are not worth it.

As a side effect, solar panel on the back of your phone would degrade your battery faster because the heat from the sun will heat up your battery and reduce cycles. If you drop your phone, now the back of your phone is vulnerable, because the solar panel would break. Not that its a problem for people using things like Galaxy Edge phones where you can break it anywhere.

Only solution I have is a fatter phone. Early last year TQTHL released a 12,000 MaH battery for the Note 4! Yeah, my phone is absurdly fat, but charging every 3 days is the new normal for me.

Battery cases are not the solution as they are inefficient and fragile.

My Galaxy S5 has been using a 7500 MaH battery from Anker since release and it still is incredibly long lasting. Because I still have the original OEM batteries that are essentially unused, I will bundle it all together when I sell them.

If Apple or any Android OEM release a new phone this year with expandable replaceable batteries, I will buy it ASAP.

They are almost at the current tech limit right now with 7nm, and it is getting crazy expensive the smaller they go. I expect we are gonna be stuck at 7nm for quite some time until a major breakthrough comes along. I gave myself some wiggle room with 2030. (Since that is when I think they will actually have something out there that makes economic sense to implement.)
Would love to see them find something that is financially feasible for mass production under 7nm, but as of right now, that is a long, long way away.

Yes, I know about those and other research projects, but none of those are even close to have consumer versions any time soon.
About all they can currently do is have thicker batteries.
Maybe they will have some kind of wireless charger that you can carry around with you, or have them installed in some stores/places that will help.

Actually, tesla and samsung already are bringing the next gen to the market, supposedly, MicroSoft is selling the note 8 with the new tech today. So... there's a bit of hope.

the Snapdragon 855 will be built on new 7nm process technology. I must be just optimistic!

 

[Insomniator]

Between wireless charging, portable chargers, battery cases, and standard batteries already lasting a day under normal use --- who cares about week long battery life?

Not that I'm against thicker phones for people that have special use cases but as long as the battery life remains reasonable I have no interest in anything thicker than say an S7 (my current phone).

 

[EXCellR8]

I'd rather have a thinner phone with hot-swapping batteries rather than a long-lasting sealed one. I'm fairly slow to upgrade my phones, and I'm still using a G4 right now, but I like the convenience of being able to charge spare batteries on the side and then just quickly swap them in if I need to. Probably in the minority with this but it works fine for me; if the phone took ages to boot up I'm sure I would find something else.

Sure, you gotta pack a spare battery if you're away but they'll fit just about anywhere; you can find emergency USB chargers everywhere nowadays.

That would be nice but it wont happen, because we will all have 1000-2000mah batteries if that at that time that are the size of a button cell 2032.

Look back to the first cell phones, not the bricks but the first small enough for everyday use phones, like the Nokia 51xx for example. Note how just its battery is larger than most whole phones today. As phones become more power efficient batteries shrink so we can have smaller and sleeker phones. Every cell phone i have ever owned has had a physically smaller battery than the one it replaced, and most also lower capacity. I expect this trend to continue, and battery capacity will keep going down as batteries are shrunk to have smaller phones.

So we may have more efficient CPU's in 15 years, but we wont have any longer run times.

 

[you2]

There was some break through technology in batteries the last year or so - at least in the lab. Not sure when we will see the technology in phones - maybe 2019 ?

I don't think we got things that consumers necessarily want. I think we got things that marketers thought consumers wanted.

Most people you speak to want the same thing - dramatically longer battery life. And, they are willing to have thicker phones if that is what it takes. I even think this is backed up by surveys. But, marketers think we want phones 1mm thick that last for 15 minutes.

The complaining and crying is usually after the fact cause when most people walk into the store and see the big sleek phones all that goes out the window.

I fully agree, the problem is zero phone manufactures agree.
