Well so far I am very pleased with both the battery and speaker on this little phone. I've got insomnia, so I use audio books to help me sleep. Something about reminding me of Geometry class makes me doze right off.
I tossed a few audio books on my micro SD card and put them on repeat so they would go all night long. I didn't use head phones, I just have the volume on 3 or 4 sitting on my bedside table. But even at that low volume I can hear the books plain as day. And the battery doesn't even go down to half after playing all night long.
Even if I use this phone for nothing more than playing audio books at night I think it is definitely worth the money I paid! $20 well spent!
