GS2 Battery - Fake or Not?

---

I've bought a a replacement battery on eBay. It looks exactly like the original which came with the phone, except for the white stick at the top (in my HTC HD2 days, the white stick was a sign of fake - or the other way round).

Thing is: with my normal usage: calls, video, SMS, WiFi etc. it is lasting around 9hr. The original is lasting more. Not amazingly more, but 20%-30% more, and % metering of remaining battery look way more reliable in the original.

Also, a very strange thing happens in the new battery: if I turn off the phone with say 33% of battery, when I turn it on again it may go to 7%. Then it INCREASES up to 13% or more, and then back down again.

This may be a fake battery? A defective battery?

its a genuine fake;

eg: high quality fake.

Meaning, it is good enough to use (better than the unbranded ones), but I can't expect it to behave and last like the real original one?

Thanks

I have same real fake one. Usage seems similar to original and for only £10 I can't complain

where did you buy it from?

First question has as always got to be before buying a Samsung battery.
Have Samsung started selling the battery yet .

ebay has been overrun with "genuine fakes". Although they are not technically BAD, the voltage detection is almost always WAY off and very problematic, which leads me to believe the battery could harm devices with long term use. I bought three batteries for my HD2, one which I knew was a non genuine, two which I thought were genuine and only one turned out to be, but it was purchased from a US seller who sold them as genuine or full refund, taken from actual HTC phones.

I even bought a battery for my samsung digital camera on ebay once, guy said "GENUINE, NOT FAKE, SAMSUNG OFFICIAL", even sent an original (see genuine fake) box for proof. Popped in the battery and lo and behold: FAKE! Guy offered a full refund and said to ship battery back. Which I never did, because shipping back to China costs twice as much as the item you buy.

You reaaaaally have to be careful buying batteries, flash memory or any electronic for that matter off ebay. Crooks everywhere. Especially when they ship from China!
