Setting my screen brightness at 50%, I run the test till it hit 10% from full charge. No other things were done, no MP3 playback. I will be testing to see how much more battery life there is if 100Mhz is used instead soon. hopefully it hits 8 hours. __________________ Ericsson 768 -> Nokia 3210 -> Nokia 8250 -> Nokia 3330 -> Nokia 8250 -> Nokia 6510 -> Nokia 8910i -> ???

Mines either at the lowest setting indoors in dimmer environments or over the 'e' in 'Done'. 50% is nice, and bright but a bit unrealistic as to normal usage. It's the kind of setting you use to show your friends "look how bright it can get! And thats only 50%!" __________________ Chris A.

I get 5 to 6 hours with backlight on lowest. Never tried it on medium setting though. But the point is, even using it on the lowest setting cuts the time in half! __________________ This signature is intentionally left blank.

I had a T615 prior and it would give me 3 to 4 hours. I didn't time it and I had it on the lowest setting and I used it extensively from 6 am to 11:30 pm where it was down to 35%. I was quite happy with that. __________________ Vx, N610, T615, NX-80

Dropzone F.R.I.E.N.D.S Join Date: Apr 2003 Location: Singapore Posts: 895	that is about the time i have. considering mine was set at 50% brightness, it should last about 8 hours on lowest settings. I'm going to try out if there is any significant difference when it is underclock at 100MHZ, comparing to the normal of 200MHZ... __________________ Ericsson 768 -> Nokia 3210 -> Nokia 8250 -> Nokia 3330 -> Nokia 8250 -> Nokia 6510 -> Nokia 8910i -> ???

I get about 2.5 hours of Wifi usage vs the NX70's Wifi usage of 1.5 hours. Sony rates the NX70 at 5 hours over 10 days. __________________ Cheers!

This reminds me of how well I have my desktop PC setup and how efficiently I have it running. Just in case someone besides me would ever use it. Problem is, no one else but me uses it!

Sony rates the NX70 at 5 hours over 10 days.

He, he, yeah we should all start mentioning wildy differreing usage figures. With backlight off, lowest, one third, 50% full, with or without using WiFi ...

It's just impossible to name any figure that is applicable for all situations.

For instance I easily get 2.5 hours of WiFi on my NX70 with low backlight, but then I have an AP that supports the powersafe mode. I have also gotten 9 hours of usage with backlight off (while logging GPS) Between 2.5 and 9 hours is quite a large gap.

For PocketPC's there is a tool that will predict the amount of time the battery will last from measuring it's voltage periodically. It just extrapolates the line after a few measurements. That way you can quickly see what impact certain changes have. Is there such a program for PalmOS?

Another point is that in 10 days you will lose a lot of charge even with the PDA off. That may sound like a silly point, but it might be about half the battery life!! I really have had a hard reset by just letting my Clie T625C laying around for a month or so. I didn't really understand why that heppened so quickly until I saw the VeritTest Palm vs PocketPC test where they tested that a Tungsten will lose all data in around 20 days (which they claimed was very good even).
