I looked at the forums but didn’t find the actual answer to this question.
I have a 2 gig fuze that I purchased in the June, 08 and have been getting a good battery life. I have been charging to 100 % about once a week. At the time of charging the battery life is about 50 % or 70 %. I have the backlight to low, screen shut off at 10 sec. and haven’t used videos. no eq, stock earbuds, normal volume setting, and low to med. low volume while listening. I mostly listened to music with an occasional book.
This past week I purchased a 8 gig sd card and put on music and a video podcast. I noticed that within 2 days the battery was down to 25%. I figured it was because of the video podcast. (I was just trying it a just for fun, don’t plan on having video podcasts as a normal practice).
Today I added some books, on the sd card and charged up the fuze to 100%. I decided to watch and see how long the battery would last. At 6:30 pm I started to listen to some books that I just put on the card, they were short books, so After each book I scrolled to another book. I listened to 5 -(10 to 12min) books. I then switched to music. I scrolled to one album and listened all the way through without touching the fuze. Once the album was complete, I scrolled to another album and did the same. I did this for a total of 4 albums. Note: 3 of the 4 albums were on the sd card.
Now it was 9:00 pm. (2.5 hours later) and I check the settings on the fuze and noticed that it was at 68%. That is a 32% or 1/3 battery use.
If I follow the math, I will only get appox. 7 to 8 hours.
So my question is… Does the SD card effect the battery life that much? Does anyone have any other help or insight?
