battery shows always 100 percent and drops to 0 percent in afew seconds
 

Hi,

I brought a new battery at the official Nokia Shop at amazon.de. Since I use this battery the level is constant at 100 percent. There is no difference also after hours of usage. Only a few second befor the devidce turns itself of because there is no power left it shows "battery empty" message and the symbol turns from the green full battery icon to th red "battery empty" icon. Tools like battery graph are showing a graph always at the same level.

Do you have an idea what I can do to get back the normal behaviour?

Thank you Uwe

i think you got a fake battery. i too have bought a nokia battery from amazon (amazon=the seller), but it turns out to be fake. ie: full charge, than in an hour, it drops to 0%, and phone shuts down. so i returned it and bought another battery from nokia.com online store, and sure enough, this is the real deal. but at $70+ USD it better be.

I got one too from China in oem packaging and had exactly the same
problem. Fake, Fake, Fake!

There's no point in buying batteries from Ebay or Amazon anymore because there is almost no way of making sure they are real before receiving them. This is true for cell phones, laptops and everything else.

I bought a couple of laptop batteries for my old Sony Vaio laptop that claimed to be OEM, original, etc and they were fake. And no, I did not go for the cheapest ones, but the most expensive from sellers with a lot of positive feedback.

As a side note, the reason I stopped buying Sony laptops were their batteries. Replacement batteries from Sony are EXPENSIVE when compared to Asus for instance. And they don't last any longer in terms of both run time or longevity...

I have bought a number of fake batteries and none of them were as bad as the one the OP described. They don't last just an hour. If you buy a variety of cheap batteries, most of them will be decent, in my experience, and I have been doing this for years for my Nokia tablets.

Even with genuine batteries, the meters are notoriously unreliable.

I forget the topic, but someone recently found a proper 3rd-party brand unit on DealExtreme for $9 that works -right- and has a good capacity.
I think This is that one; comments seem to suggest that it's as good as the genuine ones, and far better than most knock-offs.

you got a fake battery....simple.


take your original battery and match the fonts to the one you just got. you will notice a very slight difference in font and color

Tnx

this is the easiest case ever:

1. return the defect battery
2. ???
3. profit

knockoff batteries try to keep voltage as high as possible until the cell is fully depleted = described behaviour. but it might be genuine one in which case you should have no problems switching it to working one.
