If you’ve been following along, you probably already know my frustration (and adventure) in trying to get agenuinereplacementbatteryfor my Samsung Galaxy SIII. Instead of merely letting the sellers “get off”, or pocketing a partially functioning battery, I decided to tear down and document the batteries.
I’ve had several suggestions from friends to buy it from Samsung or contact Samsung directly. The problem was, that Samsung didn’t sell the battery for the SIII on their website. The closest we got was acharger cradle with a batterywhich came up with zero stores where it could be purchased. Thanks Samsung.
I decided to e-mail them via their technical support:
Another One is On The Way!
It seems fourth time is the charm. This time, I decided to go away from all of eBay entirely, and instead spent more atKogan. When you factor in the shipping, the price is similar to that charged by Samsung (AU$42.98 with postage and freight insurance). If it wasn’t genuine, I was going to spew. This is what I got.
With the battery inside another bag, doesn’t really inspire confidence. The rear of the bag had a barcode with HC140111357 and a handwritten I9300 model number.
But a closer look at the markings show they match the genuine battery I already have. The the place of manufacture and assembly matches. The datamatrix barcode encodesGH43-03699A+EB-L1G6LLU+C5ATX12705 in a very similar way to my original encoded GH43-03699A+EB-L1G6LLU+C6NTX04261.
ORIGINAL KOGAN SUPPLIED
Best of all, the NFC antenna was felt under the battery label and functions correctly,however, the battery label itself is a bit smoother and shinier than my original and the Original Accessories hologram sticker is “stuck on top”. There’s also some residual adhesive.
Lately, I’ve been having a few charging issues with my Samsung Galaxy SIII where, despite being connected to the charger, it refuses to completely charge on occasion. There are numerous posts online which claim the problem is in the connector, the cable, the charger and so forth, but I would reckon the problem is actually with my battery. The original battery provided in the phone, once sat flush with the rear of the phone, now sits proud ofthe rear and pushes on the rear plastic shell.
The good old “problem” of swelling lithium-ion cells seems to have reared its head. While the capacity hasn’t reduced too much, it’s a sign that the cell itself is having some internal chemical reactions which may make it somewhat dangerous in the sense that it might vent due to pressure build-up.
It might not look like it from the image on the left, but it’s actually fairly swollen. It’s most obvious when you place it on a flat table and press down on a corner, only to see the opposing corner lift cleanly into the air.
It’s a sign that the battery may be overcharged, or exposed to extreme environmental conditions. I know for a fact, because it’s been with me most of the time, it’s definitely not been “baked” in the sun … so it’s likely that the charging threshold is somehow improperly set, or the cell itself is defective somehow. It’s past its warranty anyway, so it was time to hunt down a new cell.
The market for aftermarket batteries is massive, and many replacements exist, but due to my interests in preserving the NFC functionality of the phone, I decided to opt for a genuine replacement. I found one from a seller nearby, at a good price (not too cheap), and I ordered it.
Over the past year or so there has been a lot of excitement about the release of flexible displays. The mass production of flexible screens is greatly anticipated, in part because of their purported indestructible qualities – but mostly because they guarantee, bona fide, that we are living in the future we imagined as children. In this article, we take a look at flexible screens and displays and give an overview of how they work.
What is a flexible display?
If you haven’t worked it out already, flexible displays are displays which are fully bendable. Samsung announced their line of flexible screens in early 2012, branding them “YOUM” and snapping up other trademarks like FAMOLED (flexible active matrix organic light emitting diode). As Samsung is the world’s largest manufacturer of OLED displays, we expect them to be one of the major players in bringing flexible displays to the market. It’s a very exciting development in screen technology which has a huge number of advantages and extremely cool uses!
How do Flexible Displays work?
The biggest problem getting in the way of making screens flexible was glass. Glass doesn’t bend, it’s thick, heavy and breaks easily. Flexible displays rely largely on existing display technology, known as an OLED (organic light emitting diode) or AMOLED (active matrix light emitting diode) screen.
Traditional AMOLED screens use organic compounds which create their own light source when a current is passed through them. As the OLED pixels create their own light source, they don’t need a back light like LCD screen technology, but the circuitry to control the pixels is fused into glass. Flexible displays simply replace the layers of glass with layers of (flexible) plastic film, allowing for them to be bent and flexed without breaking anything.
Looking to “Corning”, the manufacturers of Gorilla Glass, we can see that a flexible protective glass coating for flexible displays isn’t completely out of the question. Their product Willow Glass will allow for the easy protection of flexible displays.

I think it will be the future for all types of visual displays, perhaps even car Dashboards or the table your are working from, the list goes on and on.
