Before, in different threads, it was question of the good NX80battery longevity, but actually, some NX80 seems to be defective.
Majority of you will to change defective model with a new, desperately it is not my case.
I make some tests for understanding and (if possible) find a solution.
Initially, I want to say that: The battery connector is very easy accesses, and that it will be possible to change easily with a second battery pack.
If you disconnect the battery a short time you don’t lose data and no reset needed.

I make hard reset before the tests. Only with the original softs in the unit.
Test 1 with Brightness at 50%
Mp3 player in the ground (mp3 at 160mbs) volume 75%, bass 1
90mn
Battery level: 80%

Test 2 parts 1 with Brightness at 25%:

Mp3 player in the ground (mp3 at 160mbs) volume 75%, bass 1
30mn Battery level: 97%
60mn battery level: 87%
120mn battery level 73%
Stop the machine for 30mn rest. (Outside the cradle)
After 30Mn, I reopen it; the battery level goes up to 81%
Test 2 parts 2:
In the first minute, I loss 3%, the battery level is 78%
After 30mn the battery level is 63%
After 60mn the battery level is 53%
The machine stops after 4.30 hours use.

Conclusion: after use 3 hours, I loss power 50%.
Ok, I remove the battery and connect a big light bulb in the battery connector. The light is very bright and not present variation power like a poor battery.

I remove the light and reconnect the battery in the NX80, the power up 20%.
I remake this operation a certain number of times and the NX80 to start with unknown to manage the battery, like in the full power: with brightness at 100%, full CF and memorystick. With a battery level 0% ?????

I use it 15mn before the total crash of the NX.

I know this battery type can’t need drain like old models, but test is test, and in other threads, some people said positive results. ???
I drain the battery with the bulb light connected up 3 hours with a very full brightness light before the final battery crash.

Recharge 6 or 7 hours (full charge), new test:
Brightness 25% Mp3 in ground, vol. 75 Bass 1

60mn, the battery level is 90%. (87% before)

Conclusion: drain the battery is not necessary. I think the battery is good and the unit has battery management problem. Bug? default? Hardware or software?

Hmmm....but from your tests...it doesn't seem that your NX80's battery life is that bad?

The battery indicator is only relative and is far from perfect. There are many variables that can affect the readings. After a rest, a battery can actually regain some life, but only for a very short time.

Battery life will also depend on what the given function or app is in use at any given time. Using WiFi for example will consume more power and have shorter battery life than using the MP3 player when the back light is turned off.

Deep cycling the battery should have no impact on it's capacity or memory effect. The battery is well controlled by it's associated circuitry.

Ricleo:



Yes !!
In the same condition for 3 hrs, your battery level is 80% and my is 50% only with Mp3 player in ground and Sony launcher. Not bad!!

n2ifp:


No no, i make my test after a hard reset, only with the sony softs in the rom.
Ok, i put in a CF 128mb and 128mb Sony MS.
My mp3 are in MS (Of course, after an hard reset, I don't acces mp3 in the CF)

Thanks

Hmm...I think the CF maybe a factor in the battery tests.. I don't use the CF slot for MP3s, and I've heard that the Sony CF Driver drains power whenever a CF card is inserted, irregardless of whether the CF is being used. and your second test, is the one I find reasonably close to my usage patterns. I use my backlight at 25% too. 7% isn't really way off?

Mp3 player in the ground (mp3 at 160mbs) volume 75%, bass 1
30mn Battery level: 97%
60mn battery level: 87%
120mn battery level 73%

Is it really true that leaving the CF card in the slot will drain the battery? I always leave my 1GB Sandisk in my NX80V but haven't noticed any difference in battery life. Maybe I'll keep an close eye on the battery level and will keep you guys posted.
By the way, the battery level drops around 5% after watching a 10mins clip from the CF card, does it sound right to you guys? The battery level does bounce back for a couple percent after a little rest though.

ALL Memory Cards have some residual battery drain, some more than others. Even when they go into the sleep mode. It has nothing to do with the driver, I see many users refer to the driver, but that is a misnomer, of course it's not the end of the world though...

Hmmm.... I see... my assumptions came from the battery test comparisons between Eruware Driver and CliePet's/Sony's driver(which came from the NX73/80). Some users commented that with CF card inserted and unused, the battery on the Clie using the Sony Driver drained faster than the Clie using the Eruware driver...

Oh yah, and I'm not talking about the 30% low battery limit of the sony driver and the 15% limit of the Eruware driver for those who know what I'm taking about..

Can't seem to find that old thread...haha...too many threads about the CF drivers

Ok, the above is a thread that talks about CF battery drain..some users say there's more, some users say theres no difference in battery drain...I think maybe the mount/unmount feature of the Eruware driver helps keep additional CF battery drain down? Make your own judgements... haha, Larry, I see you have replied in this thread about the sleep mode and residual drain as well

And another one.. http://www.cliesource.com/forums/sh...battery +drain
