Maybe Elon save the last invention for the best, i read some academic research, there are some composite material, but in the end maybe the lithium is just good for the less cost.hmlongco said:Apple would be better served pouring some of their billions into ongoing research and development of solid-state battery technology. Having a phone capable of recharging in a minute would be a game changer and a clear marketing advantage.
We're almost there with Aluminum, hopefully sooner than later :KenThod said:So actually, we are now much more closer to see a device with fast charging, i agreed with Hmlongco, recharging in a minute. So but i would say it can be done soon maybe like 15 minutes for a full charge. Right now, in 30 minutes you can get half full charged
Aluminium-ion battery - Wikipedia
Still in research of course, but promising. Some features already reported from different researchers :
- ORNL's battery producing 1,060 Wh/kg versus 406 Wh/kg for Lithium
- Stanford claimed an aluminum-ion battery with a recharge time of about one minute, lasted over 7,500 charge-discharge cycles with no loss of capacity
- University of Maryland made a prototype aluminium/sulfur cell which demonstrated an energy density of 800 Wh/kg for over 20 cycles
- Zhejiang University announced 3H3C design of a battery using graphene films as anode and metallic aluminium as cathode with impressive properties :
- The battery works well after quarter-million cycles retaining 91.7 percent of its original capacity.
- The battery can be fully charged in 1.1 seconds.
- The assembled battery works well across a temperature range of minus 40 to 120 degrees Celsius.
- It offers a high current capacity (111 mAh / g 400 A / g based on the cathode).
- It can be folded.
- It does not explode when exposed to fire and the materials used are non flammable.
Aluminium-ion batteries have a relatively short shelf life. The combination of heat, rate of charge, and cycling can dramatically decrease energy capacity. When metal ion batteries are fully discharged, they can no longer be recharged. Ionic electrolyte materials are expensive.

I was very happy and will certainly not touch that switch. Well, I might want to prove a point and try it out one day taking videos at home and having a charger nearby.
All the whining idiots that will flip the switch and turn back their phones to 'sudden crashing mode' might finally understand that Apple was right all along. But of course there will also be the usual unavoidable complainers that will bitch that their phone now crashes unexpectedly while failing to feel any speed increase. Why, I even suspect we might have some here shortly well before the actual update.
iPhone 6s Program for Unexpected Shutdown Issues - Apple Support
So I called the nearest Apple Store which is over an hour away and at the time they couldn't / wouldn't confirm if they had any batteries in stock ?!? Which was very odd.
But then soon afterwards the update came along and fixed the issue so I didn't follow up to see if they were managing the procedure a bit better or more Apple-like, figuring that I would revisit this later on before the program ended to maximise the life of the replacement of course. And here we are, the program is almost irrelevant save perhaps the 29$ fee which I might still be eligible to forego.
Soli said:2) A bit of a segue from the article, but my issue with this change to iTunes is that Apple hasn't updated their webpages for iOS apps to support this change. Every time I find an iOS app that I want in Safari on my Mac—which my preferred way to search for apps—it was launching iTunes can't load the iOS App Store which would then launch the website again which at first did this repeatedly. Now they seem to have fixed this but their website still has "View in iTunes" links, which will cause this attention to detail(?) error.
NoMoreiTunes Safari Extension
I've been using it for years to prevent iTunes Preview and App Store pages in Safari from launching iTunes. Works as advertised.
Marvin said:Location apps drain the battery more quickly in the background. Having a map open in the background with the GPS active drains more quickly than with GPS deselected. The following site lists a few social media apps that drain battery in the background:
I would add 3 apps to that list, Camera, Tile and SAQ (a local liquor board app with a fidelity card barcode scanning feature).
I've had the hot phone symptom a few times where it was still hot after many minutes asleep. It was after using Camera, particularly panoramas or videos. I assumed it was uploading to iCloud but it seemed to take longer than expected, yet it also did it with cellular or roaming turned off. Closing the camera app did work but not always. Only a shutdown and restart cooled things off … and stopped the visible power drain as well. I first noticed this about 4 years ago on my 4S and still more recently with my 6S.
I use 24/7 to monitor my sleep, which uses less than 10% battery life. One morning I had very little battery left and when I checked battery usage, much to my surprise, it registered Tile at 46% in the last 24 hours and around 30% for the last 7 days. I had only opened it for a day or less … a few days before, while travelling to check if the aging Tiles in my luggage were still responding. I promptly turned its Background Refresh off, yet Tile is still 13% for the last 24 hours and still there in the last week for 23% a few days later, so it is still a huge hog. I’ve now went to Tile’s settings and turn Location to ‘While Using’. If there is still some activity I may just shut its Location off, I don't really need it unless something's gone missing.
Finally, using the SAQ fidelity card scan at the cash could leave the phone hot a while after since it will understandably crank the brightness up for the scan but won’t always turn the brightness down afterwards, even when going in other apps. Still, I’ve been back from the store 4 hours now and it’s used 15% of my last 24 hours for less than a minute’s worth of actual usage. I don’t remember noticing this bar code scan behaviour with Wallet or even Passbook before it but I’ve only used it a few times. So I can’t say if it’s the API or SAQ’s implementation that went rogue.
All this to say that there are definitely real use cases of misbehaving apps that need to be shut down every now and then, and some immediately after use. And this is a very small sample size … which includes a ’Stock’ app BTW.
lkrupp said:I remember Microsoft’s tactic. After a startup announced or released a new product Microsoft would immediately announce that they were working on the same thing and that it would be better. Consumers then often waited for the Microsoft product instead of buying the startup’s product. Microsoft would then buy out the now failing startup and release the original product as its own. Evil personified but it worked for a long time, along with the equally evil “embrace and extend” policy that suffocated innovative software.
Back in the 60s during the CDC 6600’s Five Year Reign :When [Seymour] Cray’s CDC 6600 streaked ahead in 1964, IBM chief Tom Watson, Jr. was furious. IBM quickly pre-announced faster models of its System/360 computers, drying up CDC’s sales.But IBM never actually shipped its “6600 killer,” and CDC president William Norris responded with an antitrust suit.
