Currently lithium-ion batteries degrade with every charge where the cathode starts to breakdown. This affects anything powered by them from Nissan milk floats to smartphones.

The US government and Stanford university have designed a new cathode that is self healing and are looking at 500 charge cycles for smartphone batteries (about 18 months use) and 3,000 cycles for milk float batteries (about 10 years use) with no degradation in the batteries capacity. This is a x10 improvement on the current situation.

I've had my smartphone for three years and a charge still lasts about two days. There is probably some degradation, but not that much.

As with most Batteries, cycle charge them properly, avoid running them completely flat for long periods and dont continuously float charge them when there fully charged.

And use the OEM charger that came with the equipment rather than some shitty Chinese copy.

Same here Steve, I easily make 2 days on my S3 running a custom ROM with various power saving tweaks applied that you just can't do on a standard handset.

But nobody calls Steve and he doesnt know how to use it as a smartphone.....so it just sits there 
I can flatten the battery on my iphone from a full charge within 4 hours with certain apps i use....ie ones that use the gps and data all the time.....
But for that article to claim, only 50 recycle charges is ridiculous imo.....my iphone is on charge most days and ive certainly had it more than 50 days.....without much reduction in performance from the batt

Sleeping pills and laxatives, judging by previous cleaning problems.

Will I ever be free of such ridicule?     You'll be old with problematic bowels one day, wait and see.

They can look at your feelings of inadequacy and paranoia, not everyone is taking the pee - sorry freudian slip, when they undertake their risk assessment Steve, it will all be taken into consideration........

Its miss reporting as usual, you have to take worst cases and best cases to make the new tech look better.

Yes, lithium ion batteries do degrade faster than other battery technology (to make the cycle qty higher you add more material to the cathode, hence cheap batteries dont last and more expensive ones do) and they tend to be fine and then fall off a cliff.

As for charging, the charge controlers are within the phone/device so different external supplies wont have an impact (although I have seen some add touch screen responses when running off some naff supplies hinting at greater noise on the DC output on them). Good charging is key (cordless drills being a point in case) but for these applications there is little you can do.

Batteries are not and never will be the answer for vehicles and the like as there no where near the capacity needed to make them useful
