WSJ: Samsung picks Sony as its third Galaxy S8 battery supplier

Samsung is apparently hedging its bets and trying to attract battery-making talent than is not the two infamous suppliers it used for the Note 7. When Samsung's battery subsidiary SDI struggled with the high density requirements of the Note 7 units, and used unorthodox electrodes that didn't survive real life usage, Samsung ramped up production at Amperex, the other supplier which in its turn couldn't produce those millions of batteries with satisfactory quality that Samsung was demanding in the span of two short weeks.

We all know what happened, but apart from the fresh round of quality assurance testing that Samsung has implemented for his battery suppliers going forward, like x-ray exams for each piece, it also sought and, apparently found, a third supplier. The rumors that this is a Japanese company have now been rehashed once more by Wall Street Journal sources. Previously it was said that Murata will be Samsung's supplier, after its acquisition of Sony's battery subsidiary. 

Sony sold its losing battery business to Murata not long ago, but the deal is now unlikely to go through before July, so it will be still Sony supplying the batteries. Samsung has apparently been very impressed with the quality of the Li-ion packs that the Japanese company is able to churn out, so it has co-opted it as a third-party supplier. It's hard to blame them, given that Sony pioneered the Li-ion battery chemistry, and a big order from Samsung might be just the jumpstart its battery operations need.

A bunch of Sony minions here. Dude I don't care even though you try to sound like youre real. That's seems like a bad joke that a group of unreasonable brainwashed fanboys harassed a regular reader. Did that make you guys feel better? Your should be ashamed of yourself.

Meh......I say tell him. Then again I enjoy being cruel to zealots, so my thoughts may not be humanitarian in nature.

Look I know your high on bashing Samsung during the note 7 fiasco. Your negative opinion on Samsung already made you disqualify to have a valid conversation with me. Go date that masculine girl who your defended last time.

A) Bashing Samsung? Sure, I do if every now and then, but not so often that it would disqualify me from speaking about them. B) What part of anything you say is "valid conversation"? All you do is worship Samsung, dis other Asian people/companies, and try to antagonize iOS users. There's nothing "valid" about any of that, at all. C) And now you're a sexist too? Damn, and I thought you couldn't get anymore demented. Guess I ate my words, eh?

Are you blind? Did we defend Sony? Go to bed kid, your eyes and brain are tired. You just always salty while you saw some Japanese technology used by Korean devices.

Is it just me or can anyone else hear the histrionic screeching from a certain someone all the way from Korea? A certain someone that can't grasp that business is business?

The overrated Sony utilize Samsung's RAM, memory, chip, hard drive for decades, yet PhoneArena failed to publish the info. PA editors are clever how to please those uneducated Sony fanboys, anyone that criticise or touch that overrated brand will get blasted instantly. Ever take note when there are poll about Samsung? you always get the negative result from those pure Samsung haters aka Apple and Sony snowflakes. This site isn't free, at all.

Speaking about quality, Toyota Honda Nissan recall millions car each year, just so you know. The stupid idea said Japanese products are superb must be eradicated for now.

So you're saying that the S8 is going to fail because it got a Sony battery? Very smart of you

You noob, you probably dont know how to use stuff. Your claim about sony and other japanese companies being crap is BS. My launch date PS4 is about 3.5 years old now and still functions flawlessly despite using it daily as a hometheater system, music player, for youtube etc.

Hyundai has recalls too buddy. Don't forget their MPG scandal which cost them millions in settlement with the owners of some of their vehicles. Hallyu - stop hating and start loving the Japanese.

Love my 06 Honda Civic but my 19 year old GM truck has fewer problems. Replace starter after 2 years. Tension pulley snap off and had to replace that and the water pump. Replace rear control arms because tires wore out prematurely. Now there's a airbag recall. Truck loves the gas but keeps on running.

Might be Sony when it comes to phones not that good I do agree with you. But Japanese cars still remain the best especially when it comes durbiltay, Lexus start 1989 right now the best luxuries car in the market that doesn't has mechincal failer issues like BMW and Mercedes or other American luxuries car.

Maybe you're misinformed. That crappy Sony and other mediocre Japanese products don't stance a chance in our market because they're inferior by our standard. So to say I will get the S8 with Sony battery is totally zero sense. If Samsung insists to do that, we will protest and maybe in one or two days, the CEO will get fired.
