Is tin the secret to longer battery life?

Researchers at Washington State University think they can increase battery life 2-3 times by switching to tin-coated anodes...

Why can't the companies pool the money that they waste on patent litigations for a greater cause like long lasting battery life?

That will probably happen if Samsung and Google stop copying Apple.

Is this another of Taco's notorious alt accounts? geesh.

No not my account, but i agree with the statement.

The irony here of calling me a moron while making a grammatical error that's learned in the 3rd grade.

aww.. is da wittle baby troll picking on spelling again, thus proving that he has no actual argument left? aww.

Remixfa, I've had a crush on you for a long time now. You are the geekiest phone geek I know. :)

People are talking that oil company's has bought up all the patents for better batteries. :)

Would surprise me.... GE sat on a patent for a 10 year light bulb for like 10 years. I also remember GM buying a patent for a rotary car engine that get the same performance of a V8 while only running on 4 cylinders using 1/3 if the fuel.

I don't think that last part about GM is correct at all.

expect a chinese company to try to buy or copy this technology.

Motorola: get the f**k on this. Give us a new Razr Maxxed Out with a 3300 mAH battery and 63 hours of talk time. You know you want to.

I saw the razr and razr maxx have a high sarr rating. Wonder if the battery has anything to do with it.
6. Sniggly (Posts: 7219; Member since: 05 Dec 2009)
Nah. Motorola phones almost always do. They skirt the edge of legal radiation limits because they stuff freaking powerful radios into their phones. It's why their reception and call quality are usually so good.
No worries though. I've been using Motorola phones for years, and I have no crippling tumors yet. Though I have grown a third eye. And I can suddenly jump really high. And I have a voracious appetite for human flesh now.

I have noticed the sarr ratings for moto phones are usually high.
All kidding aside I just don't like the idea of my phone pushing the legal limits of radiation.
23. Sniggly (Posts: 7219; Member since: 05 Dec 2009)
Why? If it's still in the legal limits, it should be pretty damn safe. Look at Martin Cooper. He's been using cell phones for over 30 years and he's fine.

maybe taco should switch to moto, it might mutate him into an actual human.

For that Moto is NOT at all enough... How about Cheap Chinese clone mobile phones selling for 10 to 20$ and SAR rating also in same range (10-20w/kg instead of

yayyy i hope it gets into smartphones before i decide to buy my next one :)
btw i have a technical question.. doesnt the charge time decrease if u use a higher voltage charger?
7. Sniggly (Posts: 7219; Member since: 05 Dec 2009)
I think it can. Car chargers usually charge faster, but at least the rule of thumb used to be that you should only use a car charger when necessary.
10. biophone (Posts: 1897; Member since: 15 Jun 2011)
Who really cares about the charge time anyway. A small price to pay for a larger battery.
13. GuiltyBystander (Posts: 199; Member since: 05 Mar 2012)
Thankfully by the end of the year, we will have USB3 chargers so that should help with the charging times.
11. troutsy (Posts: 287; Member since: 17 Feb 2012)
Charge time does get shorter, but battery life (in terms of number of recharge cycles) would be shorter and there would be much more heat generated on the phone.
The batteries I've worked with are obsolete technology now, but the sweet spot was to charge at a rate of 10% of the total capacity per hour to preserve maximum life. It's not the size of the battery that affects the charging time, but rather Motorola may have chosen to charge slower for better battery life or is using a carry-over charger that was intended to handle much smaller batteries.
22. DigitalBoy05 (Posts: 203; Member since: 04 Jun 2011)
Thats genius if motorola is in fact making it take longer to charge to maintain a healthy battery. Its not like you can take the battery out on the maxx or razr if it craps out on you.
15. remixfa (Posts: 14251; Member since: 19 Dec 2008)
dont do that. voltages are set for a specific reason.. so you dont BLOW UP the device. higher voltage also = higher heat which can damage the device permanently. Also you are more likely to damage the battery.
If you use a car charger, only use it until its "almost" full. Car chargers never stop trying to cram juice into the phone, so if you leave it on there for too long you can quickly damage that battery. I've seen a brand new phone need a new battery in 3 weeks because the moron kept it on the car charger for 3 or 4 hrs worth of daily commute.

No. You need a higher amperage charger. There is an upper limit though. Almost all lipo batteries can be charged very safely at a 1c rate. That's 1hr charge rate. Most can take 2c pretty easy. You can go even higher- I think about 5c is the limit for really good lipo without fire risk. The trouble becomes the heat that is generated. Most users would be very concerned about device temps at 2c rates.

Symbian Belle FP1 is the secret to longer battery life. ;-)
20. Captain_Doug (Posts: 833; Member since: 10 Feb 2012)
I'd pay more for a battery that'd last me 3x longer as long as its in reason. A replacement battery costs like $15, I'd be okay to pay 3x that. I charge my phone like 2-3 times a day due to how much I use it. If I could make it a whole day or even 2 days, I can't even imagine.

You know if this happens we'll end up with phones 3x as powerful and the same crappy battery life.
