As a followup to my last post about the surprising longevity of the Sony Ericsson P990i battery under (light) WiFi usage, I ran a similar test on the Nokia N95.
Again, I connected Salling Clicker 3.5 (non-public beta) via WiFi to my computer and went to bed. As with the P990, in the morning I was able to pick up the N95 and control iTunes right away. Here’s the shocker, though, considering the N95 has been pretty much slammed in many reviews for its battery life (or rather its lack thereof):
The battery indicator showed no signs of drainage (all bars were lit)! I suspect Nokia chose to give the N95’s battery indicator a rather aggressive “curve” (by which I mean that it will stay high for quite some time and then drop quickly). Still, I find it pretty darn impressive that we were able to stay attached to the WiFi network for eight hours without noticeable power drain.
I’ve been using the N95 for about a week now, and it’s a really quite a fun device. I hope to find the time to write a post about my experiences later. Stay tuned.

A few days ago I ran a “long-haul” WiFi test with the upcoming 3.5 version of Salling Clicker. Basically, I wanted to see (1) what kind of battery drainage one should expect and more importantly (2) that the connection didn’t go stale after a while of idleness. The results were a bit surprising!
I ran the test overnight (for about six hours) with a Sony Ericsson P990i phone, and I’m happy to report that the connection didn’t go stale; I was able to pick up the phone and control iTunes right away. What really impressed me, though, was how much battery life there was left in this phone.
This is in spite of the phone being connected via WiFi for 6 hours! I didn’t take any battery capacity percentage readouts either before or after the test, but the graphical meter on the phone’s display appears to have moved just a little bit over to the left. I was kind of expecting a nearly drained battery after such an extended connection time.
During this test, there was minimal traffic on the network. I wasn’t actually controlling anything with Salling Clicker. But, this type of “idle” connectivity is still useful; had I been listening to really loud music in iTunes, for instance, Salling Clicker would have automatically paused the music, and I would have been able to hear the phone.
It’s pretty obvious that WiFi chipsets have gone a pretty long way from where they were just a few years ago. During heavy use, I’d still expect power drainage to be significant, however. I don’t know how other phones perform quite yet, but I’ll probably try this with some other new phones.
