Incredible Battery life

[tianya]

UX-50 can play mp3 files for 16h.

If you add extended battery, 35h.

You can find this in the link below.

Sorry, It's japanese. :(

I can't translate it for u guys, cause I'm not japanese, neither speak english for mother lang.

Anyway, if this really happens, the worst problem of clie at last fixed up.

hahaha.

I want more NON-Mp3 battery specifics -- I want to read an ebook for a couple hours like on a plane flight and know I won't be looking at a 35% battery afterwards.. (My current unit would at best last maybe an hour or so before that. --- usually far less)

[jaimejr66]

The numbers given by Sony are meaningless. 16hr for mp3 (With Screen off)

30 min a day average with no backlighting. Lets do the math.

30 min X 14 days = 420 minutes or 7 Hours.

Now why even bother having a Color screen if your not going to use the backlight, so divide that into 1/3 or so.

That would mean something about 2 hours of use or so before needing recharging. That being the case, its on par with Most Clies.

I'm still waiting for some REAL world stats.

I agree that's important, but it would seem to me that the MP3 would have the greatest drain on the battery. I guess what I want to know is did they test the MP3 with the case closed and in "hibernation" mode or was it left open and going? That would be the greatest drain. I imagine the case was closed for that kind of battery life, but it still seems impressive.

There is no infomation about that. Sreens turned on/off.
And also such a battery life is due to the DVFM Technology.
But in the cases of other Clie, SJ-33 10h, NX80/73 7h, all Screen turned off.

Another infomation about the battery is movie recording/playing time.
As sony described, 1h of movie recording with max backlight, and 2.5h of playing time also max backlight(if backlight off, 5h)
(all from sony japanese homepage)

Maybe this infomation is more usefull for somebody. :)

I don't know playing movie or recording spend battery how many times then reading e-books, but I know they spend more.

You're right. Nobody know the real state. But I want to believe that this one is different from that before.

7hrs is in the range of h2210, while 12 hrs is in the range of Asus 620. Dell AximX5 goes for 14hrs. (backlight low, low clock)

I'm guessing that because of the scaling CPU, battery times are hard to make because the power drain really depends on the application you are using.

<P style="MARGIN-RIGHT: 0px">Again thats where I ask for "REAL" world test.

For example you could use the following categories.






<DIV style="MARGIN-RIGHT: 0px">Using Business Apps like Datebk5 with backlight on.
</DIV>


<DIV style="MARGIN-RIGHT: 0px">Playing games like Bejeweld with backlight on.
</DIV>


<DIV style="MARGIN-RIGHT: 0px">listening to mp3. Screen off.
</DIV>


<DIV style="MARGIN-RIGHT: 0px">Taking Still Pictures.
</DIV>


<DIV style="MARGIN-RIGHT: 0px">Taking Video.
</DIV>


<DIV style="MARGIN-RIGHT: 0px">Recording Audio.
</DIV>


<DIV style="MARGIN-RIGHT: 0px">Browsing Internet via Wi/Fi.

These are the kind of categories that mean something to me.</DIV>

[tianya]

mp3 and taking video is metioned above.

internet via wifi is 2.5h, and 11h with extended battery.

other info... not yet. :)

16 hours for MP3s with screen off isn't all that impressive compared to NX80.

I had my NX70 hit 6 hours+ with MP3s with screen off. NX80's PXA263 should be way more efficient then PXA250 of the NX70. Let's say you get 8 hours or so with the NX80.

And if you apply the upcoming version of Lightspeed for NX80, or PXA clocker that's already available and clock the Audioplayer in NX80 to 100Mhz instead of the default 200Mhz (which plays MP3s more than fine on my NX70), then you could get rather close to the "16hours" of the UX50.

ar....half the clock speed =/= half power consumption....! far from that indeed...!

Real World: Listening to MP3's and Reading / Playing games @ 25% brightness.

If it can't run for more that 3 Hours then Sony needs to take notice. It isn't good enough if I can't use my Clie a whole DAY without having to recharge it!! :(

Very true, but I never said NX80 @ 100Mhz will be 16 hours. I just said it could get close. :p

:confused:

3 hours of music and games isn't enough for you? You've got way too much time on your hands ;)

[JasonO]

Extended battery appears to double the time + some. I wonder if you can use the extended battery, then when it runs out, recharge it while you use the internal battery? Or is the extended battery not removable?

[Unregistered]

yeah but extended battery also double the unit size and add significant cost too. From the sound of it, UX only have somewhat better battery, nothing eye popping.

Some usermade review gave 11h mp3 non stop play for TG50 ; acording to this the ux50 would have 50% autonomy

I wholeheartedly agree -- on my machine 1% = 1 minute--- if your lucky...

[hayashikerubin]

the stamina on the ux is indeed due to the CPU. lowering the voltage and clockspeed when intensive computing is not required.
