Thurs 07.19.12 – Yesterday my Nokia N950 dev testing phone decided to lose all charge after only 4 hours and I knew that it was time for a new battery. With some Twitter advice from Attila and Thomas, I was able to unscrew the back case batteries, open the back of the N950 from the speaker end and then verify which battery was in my device and at what mAh.
While the Nokia N950 specs as listed on the Maemo.org wiki state that the battery is the BL-4D 1320mAh, @achipa wrote that the Nokia 808 PureView’s BV-4D battery would work as well, which I tested and it worked. As of today on Amazon.com, the BL-4D is for sale but is only 1200mAh and the PureView’s BV-4D with 1400mAh is not yet available in the US or for sale on Amazon. When the BV-4D does come available I will get one for my N950 as the extra 200mAh will help in the battery lasting longer department.
Big Thanks to Attila and Thomas for their Twitter advice, esp. on how to do the Quick Charge (carry an extra battery and swap it out).
