  5. I love about all these kinds of smartphones. Its just that, in terms of
    battery, I am more cautious. I want a phone where the battery is next to
    its priority. Just this recent, I bought new battery (from Amazon which
    is the Replacement Battery For Samsung Galaxy S3, 2100mAh Li-ion
    Battery by Procizion (No NFC) for my S3 and due to weird battery
    problems I’ve encounter. But as a whole, phones like these are the ones
    that needs to be given a fair review.

  12. thank u for telling the tips for identifying the original battery and also useful and i also done it

  13. Please be advised that the information on this page is NOT correct and has been reported to Samsung UK. I complained after receiving a battery that did not have matching barcode/production dates after following this information. I then received a refund but the seller swore blindly it was original. I then purchased directly from Samsung UK, and the battery I received did NOT have matching dates. They were two weeks apart. Most likely production date on the battery and packing date on the barcode which was several weeks later! STOP MISINFORMING BUYERS!!!!

  14. Add a comment…I lake it excelent

  15. This is a wonderful piece.

  16. Another clue that a battery may not be the real deal is the price. I have a Galaxy S4 and Samsung sells the battery direct to consumer for $39.99. Retailers on eBay and Amazon are selling supposed OEM batteries “without retail packaging” for less than $10. If the price is way too cheap compared to Samsung’s price, something is wrong. I wouldn’t buy any battery not sold in original Samsung package. “Non-retail package” usually means it is a fake, mass-produced in CHINA and does not come in the original Samsung retail box. These fakes have all kinds of issues. Limited number of charge cycles and very rapid discharge. Many provide less than the mAH stated on label and don’t meet Samsung’s specs. One fake I bought for $7.95 didn’t have the NFC chip even though the label on the battery claimed to have “Near Field Communication.” And seller only offered 90-day warranty. You get what you pay for. Want a battery that works just like the original in your new phone, buy it directly from Samsung. You may be very disappointed if you have to buy a new replacement every 3 months.

  17. i have seen that in the oem battery there is a black layer chip can i know the purpose of this thing.what does it do actually.

  18. As i have seen that in the oem battery there is a black layer chip stick with battery I would like to know the purpose of this layer chip thing.

  21. Nice information. I bought a cheapie Samsung battery on the web, it would not hold a charge. I used your info and determined it’s a fake. It stands to reason than a $50 battery sold for seven bucks on the ‘net would be suspect. Hey, there’s a sucker born every minute. Thanks for the education.
