I’ve been torture testing two clips, fully charging them and then playing an album repeatedly and measuring how long the battery lasts. My Ogg bitrate tests are significantly shorter than the mp3 VBR tests, as much as half the battery life for Ogg Q8.5 vs mp3 V0.
Can someone replicate the test with the Fuze. I suspect the results will be similar. My guess is the Ogg decoder runs the Arm processor at a higher clock frequency.
Here is my link to my clip test: http://forums.sandisk.com/sansa/board/message?board.id=clip&thread.id=14326
I’d do the same, but I have loaned out my Fuze, and it doesn’t look like I will get it back >.< LOL
I will buy another one. It just hasn’t been a priority the Clips my preferred player atm.
Here is the summary that’s shows the difference.
Playing Time - Comparing the Silver Sansa Clip 4GR1 vs… Black Sansa Clip 8GR2: 1/4 Volume
Silver Flac Lvl8 : 09:02:00 * Silver wins lasting an hour longer than the Black 8GR2 *
Black Flac Lvl8 : 07:46:00 I don’t understand why??? I’m going to retest again
Silver Ogg q8.5 ~256k : * Going to retest - Silver died while I was away *
Black Ogg q8.5 ~256k : 08:05:00 * Black was still playing so it wins but not sure by what *
Silver Ogg q5 ~151k : 10:15:00
Black Ogg q5 ~151k : 12:12:00 * Black 8GR2 lasted 2 hours longer than the Silver 4GR1*
Silver MP3 v0 ~252k VBR : 15:07:00
Black MP3 v0 ~252k VBR : 17:18:00 * Black 8GR2 lasted 2 hours longer than the Silver 4GR1*
Silver MP3 v6 ~128k VBR : 17:40:00
Black MP3 v6 ~128k VBR : 20:47:00 * Amazing. lasted 3 hours longer than the Silver 4GR1*
Controlled testing results preferred, vs guesses and speculation.
