Hi! I just bought a sandisk sansa clip+ 4gb. My concern is I don’t know how long I should charge it and in the first 3-5 times of charging do I need to charge it fully and discharge it fully again and again? What’ll I do when im loading songs into it? Is it harmful everyday I connect it to the computer to load some songs altough it’s not discharged? It’s known that when you connect it, it’s also being charged.
3-4 hours should be sufficient for the intial charge. The Li-Po batteries used in these things do not require a full dicharge and full re-charge like older re-charable batteries of different types. In fact, this practice is detrimental to these batteries. A partial or top-off is ideal so no plugging in in daily to add or delete songs is not harmful.
More info on these batteries can be found via Google.
Additionally, don’t use it while charging. That would accelerate the aging process of the battery.

Really? Why would that be? I’ve never heard that point before.
Neither have I.
