Battery Test : Nokia N9
Vs. comparative smartphones

GSMArena did the battery tests on quite a few comparable smartphones recently, culminating with the Galaxy Nexus on 30/12/2011. I refer below the most likeable five [5], which were under consideration while many of us were on the N9 foray. It's amazing to see that our beloved MeeGo-Harmattan fared much better than the other [most] expected ones.

3G Talk Time:
How the battery went from 100% to 0% on talk time over a 3G network.


Web Browsing:
How a fully charged battery took time, while refreshing web pages with their automated script, to deplete its juice.


Video Playback:
How the smartphone/s used 90% of their battery (the trial ends there) after continuous video playback.


Overall Score:
They conclude with the most important of their tests, the "overall usage". That number [in red] means that you will have to charge that smartphone every that many hours if you do one [1] hour each of browsing, video playback and 3G calls per day.










CONCLUSION:
Apple iPhone 4S works out to be the overall leader with 45 hrs. of Endurance Rating, while doing fairly well under most individual tests, sure some others beat it irregularly... however, our own Nokia N9 doesn't seem to much lag behind - scoring 39 hrs. of endurance, beat only by the SGSII at 40 hrs... which is incognito to me. While the Galaxy Nexus sure was a disaster at 35 hrs. faring nothing scholarly at the individual tests as well. Quite drab I'd say [though non-technically!]... while even our 'twin-sister' with WP7.5 Mango under the same shell fared better !

But, man-o-man! Did the Nokia N9 rock?
Second best [keeping the SGSII at par]! That sounds good... what with all the talk about 'idle consumption', 'older processor', 'poor battery life' and the likes? GSMArena suggests that reasonably heavy users should expect to get about a day and a half from their N9s. Good enough?

Qorax

Ps.: I'm a non-techie... do not know the wherewithals... but my overall experience with my N9, since around a month, has been astounding, vis-a-vis my iPhone4. And GSMArena seems to echo that!
