battery life on standby lasted less than a week
I bought a ipod nano 7th generation in March 2016. I usually use it during workouts, 3 times a week for 20 minutes. Most of the time, no music, or bluetooth is running and the screen is turned off by me pressing the on/off sleep button. However, I get very erratic battery life. Sometimes, it can hold the charge for almost 2 weeks. But I charged it last weekend and used it twice this week so far. Now the battery is dead (it asks me to connect to power when I turn it on).
Can someone tell me if this is normal? Beside, resetting the ipod and re-calibrating the battery, is there anything else I should do?
Thanks,
Gary
