Samsung Battery Technology Adapted From EVs Could Boost iPhone Battery Life

lol - a company with a reputation for exploding batteries doing experimental battery production. Let someone else test it first.

If you get out of the fan realm long enough, you'd realize that the battery used in the note 7 was fine. It was the amount of room in the device that was at fault (you probably do already but like to use snarky 6 year old jokes against the brand you hate). You'd also realize that apple is no stranger to the same thing (i.e. Macbook banned on flights by FAA, iphones catching fire, watches exploding). Apple PR just does a better job with the media at keeping these things from getting big and samsung users aren't as adamant about constantly bringing these things up.

Lawsuit Claims Swollen Apple Watch Batteries Can Lead to 'Substantial Personal Injury'

Every generation of the Apple Watch has a battery swelling defect that can cause operational failures and injuries from broken screens, states a new...

iPhones won't have significant battery life improvements. Every improvement from the battery will be offset by more power hungry hardware, software or the phone getting thinner (yet except where the battery is). Their core business model is selling you a new phone when the old one is getting slow and the battery can't get you through the day.

But I just upgraded from XS Max to 13 Pro Max and got more than twice as much battery life, while the phone got thicker and heavier...

I hope this works out. Better battery life is always a good thing.

Don't tell Apple about the 10% increase in energy density. They'll just make the iPhone thinner to offset the increase.

They can add a few millimeters to the phone and give me a bigger battery overall. I dont need a sheet of paper for a phone. Some weightiness is fine, Apple.

Do you remember the last time the iPhone got thinner? The thinnest phone was the 6. They have been thicker ever since that.

The last time Samsung tried to shove batteries too big to fit in their phones - they went ???

 

[bobenhaus]

Oi! Don't go lumping yer average Apple user in with the fanbois.? Most of use are impartial to slightly biased--we ain't fanatical.?

Ok . typical bias user towards anything Samsung .

One thing that excites me about the switch to EVs is the massive investments in battery technology. The battery is one of the likeliest parts to fail and we’ve had the current technology since the 1990s. Imagine what a breakthrough in battery tech could do- maybe weeklong battery life? It would be huge. I wonder why Apple isn’t massively investing in battery tech like they are with audio, AR, and silicon. From a cynical point of view, if batteries got too good, that would really hurt the upgrade cycle…

What would be Apple's competitive advantage in battery manufacturing? Tens of billions of dollars are spent on battery R&D every year, as everyone knows even small steps forward may be very valuable. Even if Apple invested billions into battery development, it is unlikely it would be able to make a significant breakthrough.

Also, the value of a battery innovation is smaller for Apple than for Samsung or Toyota. Increasing the battery capacity by 10 % (for the same price, durability, and size) would be huge for a battery or EV manufacturer, but not that important for Apple.

What good is “dense” if the batteries‘ life cycle shortens by fully charging it (like EVs)?

The life time of an iPhone battery is shorter when charged to 100 % than when charged to 80 %. The longer a battery spends close to 100 % (especially at higher temperatures), the shorter its lifespan is. This is nothing unique to EVs.

EV batteries are more durable than smartphone batteries. EV batteries need to be optimized for longevity and adverse conditions. They tend to have very sophisticated BMS systems and active temperature control. Mobile phone batteries are optimized for small size, high capacity, and low cost; a three-year lifetime with 20 % capacity drop is quite fine, whereas in a car it would be completely out of question.

How is that different to this: https://www.wired.com/2015/03/apples-new-battery-tech/

 

[sherwinzadeh]

Uh...I though Apple is already doing that. They've had stacked batteries for years since the MacBook Air, no?

No. Samsung is free to do any kind of R&D it likes. Unlike Apple which has a long history of acquiring tech instead of doing any R&D of it's own.

 

[Saturn007]

Those companies all had issues with their batteries catching fire and had to do recalls.

Yet, Tesla is under investigation for all manner of problems, including auto drive, working conditions, safety and SEC violations, etc. Not to mention, but I will, many reports of spontaneous combustion caused by [drum roll] its batteries!

 

[Boris Bronson]

Blimey, I’ve upset a few Seoul fanbois there. ?

 

[huges84]

Wow. So many uninformed comments. People are saying that batteries haven’t improved. That is patently false. We have had slow but steady gains and today’s batteries are way better than 10 years ago. Battery R&D is one of the top investment area in the world. Lots of that money will not result in large improvements. People that want Apple to invest in battery research are asking them to play the lottery.

The Note 7 battery debacle cost Samsung about $5B in recall. This was an extremely expensive lessons learned. If anything, they would be the first company to understand what not to do again and have developed new processes and procedures to prevent this from ever happening again. This is probably why they are doing pilot runs and only testing it on 4 of 12 devices in the M series phones.

I guess with the batteries, Apple would place smaller batteries into their iPhones to make iPhone thinner instead of longer battery life

 

[svish]

Sounds good. But might take some time for it to happen.
