Having just received a Nokia N96 I thought I'd take a look to see how power consumption differs from the Nokia N95 8Gb, especially given the potential concern over the small battery in the N96 (950 mAh) compared to the N95 8Gb (1200 mAh).
Firmware levels were v20 on the N95 8Gb, and v11.018 in the N96
Whilst I've tried to ensure no additional tasks are running, these are just initial measurements, all taken with the Nokia Energy Level profiler, and in OFFLINE mode.
| State | N95 | N96 |
|---|---|---|
| screen off | 0.02W | 0.01W |
| screen on, backlight off | 0.16W | 0.10W |
| Screen on, backlight MINIMUM | 0.22W | 0.43W |
| Screen on, backlight MAXIMUM | 0.41W | 0.69W |
Now I haven't looked at media streaming, connectivity, but this does throw out one significant issue
with the screen active the N96 sucks significantly more juice than the N95 8Gb
In fact this is significant enough to contact Nokia. Quite possibly it's related to the screen, perhaps the CPU is being run faster or similar, but as it stands this difference will massively comprimise battery life on the N96

Hi everybody,
I am trying to establish which tool(Energy profiler, Performance investigator) is better to estimate power consumption in nokia n95, right now I have the next problem(in online mode):
I have mapped the measures(5 mins) for both tools, the behavior between graphics seems almost equal, but the values are completly different. I mean: With Performance Investigator the values are around 8 times bigger than energy profiler values.
The average related to power for both tool, under equal conditions is:
Energy profiler: 0,08W
Performace Investigator: 0,7W
I tried the same procedure with an interval of 10mins and the result are almost the same.
Does someone know what is happening?.
Thanks in advance.
