https://community.sony.se/t5/portable-audio/nwz-a15/m-p/2035997#M2635 <P>ive just bought an nwz-a15 MP3 player and have a question about battery care. The manual states that the normal battery life has approx 500 charge / discharge cycles. How does the fact that the battery starts charging as soon as you connect to a PC affect this? Should I wait for the battery to fully discharge before uploading new mp3s or is it safe to just attach to usb for short periods at any time?</P> Sun, 11 Oct 2015 15:04:59 GMT GraemeCaUk 2015-10-11T15:04:59Z https://community.sony.se/t5/portable-audio/nwz-a15/m-p/2035997#M2635 <P>ive just bought an nwz-a15 MP3 player and have a question about battery care.
