If you followed my reviews of the Nokia N9’s older brother, the QWERTY slider N900 last year, you will remember that I found it an excellent device. Its main sore thumb, however, was poor battery life.
As such, one of my apprehensions concerning the N9 was this very issue: how well would this new kid on the block manage battery power?
As a rule, the N9 takes me through a full work day of email, web browsing, Twitter, calls, SMS and a few others. I hardly ever have to worry about running out of juice, and often go over 30 hours on one charge.
It really is amazing, considering that I had to move on from the N900 primarily because of its poor battery life.
The guys at GSMArena have also setup a new battery performance test for devices. Incidentally, the N9 was the first device to be subjected to this new test, and here is the verdict:
That gives the Nokia N9 a final score of 39, meaning that the smartphone will need to be charged every 39 hours if you do 1 hour of each of the three activities described above [3G voice call, web browsing, video playback – Editor]. So reasonably heavy users should expect to get about a day and a half from the N9.
As you can see, GSMArena’s tests seem to be in sync with my own average daily usage.
In a nutshell, the Nokia N9 seems to be one of the most power-efficient smartphones in the market at the moment. This dude keeps pulling surprises!
