Battery not original Samsung.
I got this battery MSM-HK as a spare battery for the Note.
I charged both the stock Samsung and the MSM-HK battery until it indicate 100%.
Then i compared them to each other with the batteries installed and running in an identical situation.
What i found was that the stock Samsung battery drains rather faster than the lowly MSM-HK.
That this mean that the MSM-HK battery has a more longer battery life between each charge?
i'll wait until i have charge/discharge cycle this batteries at least 3 times before i can make a conclusion.
The MSM-HK battery cost me just 2 hamburger meals.
