Hate to throw anything away and none of my current phones, etc. can hold many songs. Before I replaced the battery, the old battery would only last 10 minutes before shutting down. Now it lasts for at least 12 hours, even longer I think than the original battery.
Great, had my electrician bother-in-law do it for me. Best brother in law in the world.
If you have an old device that is not working, it is always worth a try to fix it. Just watch the videos on youtube and be patient. Or find a friend or relative to help out.
