first charge u3

[Austrian]

today i got my iaudio u3 and I wanna make the best of its battery life.. so my question is:

once I read that you have to use it till it is empty the first time, because the player comes already with a certain state of charge,
the user guide though advises to charge it fully before first use..

so what's better then? is it a grave mistake if i tested the player for 2 minutes if point two is the right way?

thank you guys

Charge it till it's full, then use it till it's empty again. After that the charging circuit should be calibrated.

It's said to be best for Li-Ion batteries to be topped off constantly, and discharge them completely once a month, or every 30 charging cycles.

ok.. any damages due to my euphoric first 3 minutes test session?

If the U3 didn't explode right away, you're good to go.

[Austrian]

lol no still there is the whole thing.. but you know I meant the thing with the first charge - like propably many other I couldn't resist of trying it for some minutes..

[dfkt]

That sure is no problem. The full charge/discharge cycle on first use is mostly to make sure the battery icon shows the correct charge and is calibrated right. It won't hurt if you listen a bit, with the U3 right out of the box.

thank you

[Austrian]

btw.. should I charge it now up to 15 hours or just "fully"?

[dfkt]

15 hours sounds a bit extreme... I guess it shouldn't take more than 3-6 hours to complete the first charge.

[Austrian]

so the 10+ hours of battery-training are just gossip..?

" Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days."

Well yeah, there's a lot of esoteric assumptions around the whole charging issue... I'd go with the stuff Batteryuniversity says - they seem to know what they're talking about.

[Austrian]

while charging, is it normal that the player shows the charging-display for charging via PC and not the symbols for AC-charging? (maybe they are just shown using the original adapter? - I'm using the Artwizz Plugg)

[dfkt]

I didn't know that there are two different charging icons on the U3. My X5 shows the same icons for AC and USB charging. But then again, the U3 can only be charged over the USB plug - there is no dedicated AC input, right?

[Austrian]

no, there isn't any seperate slot.. funny that the manual shows a picture of a charging u3 using AC-to-USB slot with different symbols than via PC.. but as you already noticed, there isn't anything but USB port..

[dfkt]

Guess it's just a mockup then, by an eager manual designer.

[Andreas]

when connected to the PC its, well, connected as well.... when using ac usb adapter there is no data transfer going on, only power

[Austrian]

well, I guess the specific symbols are only dedicated to the original AC-plug, like a kind of loyalty bonus

[dfkt]

Quick - get that plug while you can!

[Austrian]

but btw.. what will the display show when it's finished? or better consider the diode of the plug?

[dfkt]

Patience, young Jedi - you'll see soon.

It's a surprise!
