Techbaum Replacement Battery for Nokia Lumia 950

Works Great. Was a little tight fit because of the label. But perfectly satisfied.

The battery didn't work: put it in my phone (950) and charged it for several hours, the phone never started, only buzzed a few times. Very disappointed. Plus, the battery is an original Microsoft 950 battery as other reviewers mentioned.

The battery I purchased ended up being a Microsoft Genuine battery which was very pleasing to find. I had to remove the sticker that the seller had slapped over the top to see what the battery actually was. The manufacturers date that the seller had stated is not accurate and the battery is a year older than the date of 1/1/2017.Why the seller was not honest about these facts, I don't know.But all in all, the battery works as desired and has improved my phones performance dramatically.It does in fact support fast charging since it is a Microsoft battery.The seller was very fast in shipping the battery as I got it days before it's expected delivery.In the photos, the newer battery is the one I got from the seller.

From what I can tell, when using this battery the phone will not charge as quickly as with the OEM battery. With the original, when plugged in to the original charger, it would charge about 50% in around 30 minutes. This battery takes hours regardless of what charger you use. Despite this, the battery performs reasonably well, lasting about as long as I would expect.

Came to me in a timely manner when I needed the most, and what a great product!
