Samsung To Push Software Upgrade Which Will Cap Galaxy Note 7 Battery Charging at 60 Percent (zdnet.com) 120

As Samsung figures out how to tackle the big Note7 fiasco, it has found a temporary solution for existing users of the phone. It plans to roll out an over-the-air (OTA) update on September 20 which would limit the battery charging cap for the Note7 to 60 percent. ZDNET reports: The Over-the-Air (OTA) software upgrade will commence on September 20, 10 am in South Korea. Samsung is in talks with telcos from nine other countries where the phablet is available to deploy a similar software upgrade. Galaxy Note 7 has a battery capacity of 3,500 mAh, but the forced upgrade will enforce it to 2,100 mAh. The measure is meant to protect consumers who are still using the Note7 despite a recommendation to halt use. When the exchange starts on September 19 in South Korea, the tech giant will also offer to pay parts of the data fee.

      Samsung steals 40% of customers' battery life

      TFTFY

      • by goombah99 ( 560566 ) on Tuesday September 13, 2016 @05:30PM (#52882211)

        The problem is battery terminals manufactured too close together. Why does having 40% less stored energy make the problem any better?

      • Well this is a stop gap measure until you can get a replacement.
        So lowering the battery charging limit is far more ethical than having them explode on you.

        And if that lack of power is annoying... you should go and get the replacement.

  • Although I suspect that Samsung will argue that this just that Galaxy 7s will only burn 60% as hot as they would normally.

        How does that work if you "bought' the phone as part of a several year long contract? Will Samsung buy out your contract?

          yes, you'll get your money back. I traded my wife's note7 for an s7 edge and it just changed the payment. I also got a $150 card at the store I bought it, which I got to keep, and a 256 GB SD card from Samsung, which I also kept. The s7 edge, also had a $150 gift card promotion, I got that as well.
          So, this has worked out ok for me, but the note 7 was much better then the s7 edge, so that is a bit of a disappointment.
          It also took about 3 hours to do the exchange, which is horrendous.

            Then you're still under contract with the phone company. The question was whether Samsung would pay off your contract, so you can be back to where you were before.

    • Can't you get 100% of your money back by returning it to the store? And Samsung also provides replacements.

      This is what is known as a Interim Containment Action (ICA). It's merely to prevent more fires before the phones are replaced. A recall has already ordered, and anyone that owns one of these phones can return them for a full refund. [cnet.com]

        Sorry but that would be contractually unfair. Not only are people entitled to a new phone but also the cost of obtaining that new phone (time and cost of going to store), the functionality lost between replacing a phone you can not use and also the labour lost in setting up and adding data to that phone. Samsung is fully liable for all those costs as well. Those costs can be really high and Samsung is contractually liable for them in many regions (they can not legally exempt themselves from those costs tha

          Most people aren't aware of their consumer rights, and companies take advantage of this fact on a regular basis. When i bought some hardware that was DOA a few months ago the company initially asked me to send it back at my own expense, only when i refused and asserted my rights did they organise a courier to collect (which would have cost much less because they will get preferential rates from couriers).

      On the plus side, the battery will literally last forever. Charging to 90% doubles the life of a LiPo, charging to only 50% eliminates cycle-based aging almost completely (the cells will still degrade, but just as quick as they would if you didn't use them at all). 60% will likely last very long.

    Yes, Li-Ion chemistry has improved a lot in the past decade but batteries still degrade faster at 100%.

    • by guruevi ( 827432 )

      I thought most modern devices have moved beyond LiIon to LiPo and all Li devices should maintain their charge due to memory effects, even in modern batteries.

      • 'Lithium Polymer' is really just a packaging technology, the cells are still lithium-ion and charge and discharge the same as metal housed batteries.

        The 'memory effect' in lithium-ion is generally considered negligible, or at least far less significant than the stress caused by charging batteries to capacity.

      • LiPo didn't solve the LiIon degradation issues.
        The issues have nothing to do with memory effect.

            hahahahahah

            Okay now that this is done, mobile phones and laptops are no where near the point of sacrificing battery life for charging speed. They are however at the point of melting connectors, providing power in a package the size of a small stack of 50c pieces, and at the upper limit of the USB PD1 specification.

            Please put on your thinking cap, not your tinfoil hat.

      • I thought most modern devices have moved beyond LiIon to LiPo and all Li devices should maintain their charge due to memory effects, even in modern batteries.

        Li-ion and Li-Po batteries have a MUCH reduced "memory effect", relative to earlier Ni-Cad and Ni-Mh batteries. But they DO have the effect to some degree. That 's why Apple encourages users to do a full discharge-recharge cycle at least once a month.

          The memory effect is a myth [wikipedia.org], but Lithium Ion batteries eventually go bad permanently if not kept charged, but not overcharged. The apparent memory effect was something caused by charging multiple-cell packs without balancing. You'd get overcharged cells which would result in reverse charging of some cells during the discharge process that was supposed to protect them from memory effect. Now we all have balance chargers for our RC cars and planes and quads, and the only thing we have to worry about is abuse

That is to say, damaging the electrolyte by overcharging, excessive charge rate, storing an excessive charge, permitting it to become excessively discharged, or storing it too long with too much or too little charge.

      Didn't we see an article about exactly that a few days ago? A company talked about not allowing Lio-Ion batteries to charge to 100% to increase their longevity?

      Forcing a shutdown when the batteries are at 10% would probably help too, but there's the fact that cellphones can be used in case of emergencies so it's probably not a good idea.

        IIRC, the magic number is around 85% max charge. 60% is just pure CYA.

        But then, Slamdung never could design a decent charging circuit. My work Slamdung laptop burned its batteries to a crisp in short order. Even with using its fancy "Samsung Power" (or whatever the fuck they called it) charging profile, which supposedly stops at 80%, I can get only about 10 minutes (at best!) without having to "plug in or find another power source".

      • Forcing a shutdown when the batteries are at 10% would probably help too, but there's the fact that cellphones can be used in case of emergencies so it's probably not a good idea.

        All devices which run on a rechargeable lithium battery and are more complex than a cheap vape have low voltage protection. (Even a medium-priced vape has it, too.)

    • My Lenovo laptop has an option where instead of the normal mode (if plugged in, laptop charges until 100%), you can select "Battery Longevity" mode. In this mode the laptop will start charging if batter is under 45%, and stop at 50%. So basically the battery will always be between 45 and 50%. This is supposed to greatly increase the lifespan of the battery.

      • why cant windows do something like this once a week, say 2am it should stop charging until its 40%, then charge up again. A battery constantly on trickle charge for months on end will not be good - reason for past dead batteries

    • While I agree that this would be an interesting thing, isn't this upgrade limiting the upper rather than the lower charge state?

          I believe that is precisely the case. However, this Apple page [apple.com] explains it a little more clearly. So it appears that they have found that you can charge to 100% without damage, if you drastically change the charge-rate at around 80%.

      That's a cellular carrier problem, not an Android problem. They insist on having control over things they shouldn't be in control of. Apple had enough clout to tell them to f- off. Other phone manufacturers did not. Google had almost enough clout to keep their paws off the Nexus phones (though until the Nexus 6, Verizon refused to allow Nexus phones on their network for this reason).

      IMHO at this point the solution is regulation to prohibit vertical integration. Phone manufacturers make the phone and only the phone. OS vendors only make the OS. App makers only make apps. Cellular networks only own tower networks. And cellular carriers only provide service (by leasing access to towers and activating phones on their network). That maximizes competition and interoperability.

        Not only is that illegal; but it flies in the face of Apple's iOS business model. And in case you haven't noticed, their's is the ONLY mobile ecosystem that DOES work, especially when it comes to handling issues like timely software fixes.

        So now what, Mr. Smarty-Pants Communist?

    • The handset makers don't really care either. None of the other Android manufacturers has the privileged position to release updates and from their perspective if you have to buy a new phone to get updated software, all the better for them.

      Telcos should have zero say in when or how you update your device, or have any say in what you do with it in the first place.

      Actually, I was thinking how this proves that Android actually CAN push an update in short order... When it suits THEIR purposes.

      Samsung deserves every single lost sale because of this.

      Meanwhile, iPhone 7 orders are FOUR TIMES of the previous model [cnn.com]. Wonder if it has anything to do with the fact that, for a LOT of people, this is the last straw with Android and their shitbox... Well, EVERYTHING?
