View Full Version : Actual Battery time
How accurate is the 50 plus hour battery time quoted?
I have timed my playback for 20 hours and im down to a quarter left on the battery meter, I have since recharged with the quoted 3.5 hours ac recharge took only 2 hours, so maybe the battery meter is wrong?[confused]
Anyone else care to share their battery times

i've got some time where i don't need it starting saturday. i'll charge it up, and let it run down starting then, and i'll report what i get.
usually, the battery has the longest time after some recharges... and once when I was to a quarter down I was turning on a movie, watched it to the end and listened quarter hour to music... still the battery wasn't dead.. ;)
Then I got so tired, that just plugged it in, and recharged it over night...
I think the diameter is just not very accurate...
i always noticed that on my i6, the battery meter would go down from a full 3 bars to two and then 1 and the 1 bar would last the longest, much longer than the 2 or 3 combined.

The fact of the matter is that we don't know exactly what Cowon was doing on the player as videos are going to obviously going to drain the battery more than say audio. We don't know how much of each type of file they were using. The figure they provide is arbitrary at best. My guess is that they would have been playing mostly audio to arrive at the 50+ hour battery time.

Actually, we do know because they tell us:
Power
Music : Max. 52 Hours Continuous Playback
Movie : Max. 10 Hours Continuous Playback
Charge time
About 3.5 hours by adapter, About 7 hours by USB

To get their music time, they probably just put a song on repeat and timed until the music stopped. They most likely did not use the screen during this time at all.
Your battery mileage will almost definitely be shorter because you'll be using the screen to change tracks, and do other things while the music is playing. Plus, starting up the device drains some charge as well, if you turn it off and on multiple times between charges.
Factory battery times are almost never what the consumer experiences, because the factories don't test using normal usage. Hell, normal usage is different for everyone. Some people may change tracks every other track, others may listen to entire albums before using the screen.

if i recall, the stated battery and the actual battery for the X5L was quite a bit different as well.
All the Jeteffect drain most of your battery, coz the test is based on normal EQ. And you have too look at you bitrate and the format at the track.

Do you know which formats take more processing, and therefore, more power?
I guess higher compression rates drain batteries more...
So FLAC in a high compression rate would drain more than mp3 128 kbs....

Ogg drains almost twice as much as mp3 on my Clix.

of all formats, i think Mp3 uses the least amount of battery, but I don't know for sure.

That's the thing, we don't know exactly what, say, the audio paramters were that Cowon used in their testing, although in all fairness, it's probably better than what other manufacturers provide. As what has been said above, different compression rates will also create different results. It would good if someone could try different parameters see if people are getting comparable results. This could help make people aware whether they are maintaining a proper charge.

According to DAP Review, OGG and MP3 drains the battery about the same on the CLIX...the former draining slightly more.

Bs. [yes]
Mind sharing that link?
Edit:
They might have a US Clix or a 4GB one. In Sweden and most of Europe the first Clix 1 and 2 GB models were actually a U10 core w. Clix shell. Might be it.
It's the one with the Clix-core.

MP3 (128kpbs) – 22hrs 41mins
MP3 (160-320kpbs) – 20hrs 22mins
WMA (128-192kpbs) – 19hrs 26mins
Ogg vorbis (320kpbs/~Q9) – 17hrs 06mins
Ogg vorbis (128kpbs/~Q4) - 18hrs 01 mins
The slight difference is 22% (on a faster core).
