After obviously emerge product plagiarism inferior quality always at the represented at Amazon Marketplace merchants, I wanted to make sure to buy an original battery of Samsung. But that is not so simple or seemingly impossible, because, unfortunately, most reviewers do not announce their negative or positive reviews, in which the many distributors they have bought. In Internet circulate instructions to identify counterfeit batteries, but unfortunately help only if you have the battery before you leave home.
Since Amazon is performed as an official Samsung dealer on the Samsung website and Amazon is very accommodating when returning, I bought the battery for higher price than in the market place traders usual directly from Amazon.
The supplied battery was me (that is, without imprinted Samsung logo or serial number) packaged in a small white cardboard anonymous, but with the correct item number EB-L1G6LLU, but in my opinion is quite common in bulk.
The battery itself has the same weight as the bundled with my S3 battery, plagiarism are often a little easier.
Visually there is no difference between the old and the new battery is detected, production date of May this year is printed, print is not as sometimes printed faintly in plagiarism, the paper with the battery is encased, is not wavy, the gold-edge connectors have the same size etc.
But most important is the performance, that is the endurance of the battery:
After the first charge of the battery in standby kept low use (Bluetooth activated approximately 2 hours, watched about 2 hours video, power save mode enabled, WLAN and GPS off), accounted for 62 hours.
Remains to be seen how that develops after several complete discharging and charging, normally the standby time should be a little increase in low-quality batteries the opposite is the case. Should the latter occur, I will report here.
Addendum 11.08.2014: After the second full charge I was a standby time of almost 4 days to achieve (89 hours at Battery Meter 4% residual capacity). Bin thus more than satisfied!
Due to the encouraging long standby time and the No differences to my old battery, I assume that the direct selling via Amazon (not MarketPlace!) Battery is a genuine battery from Samsung.
