Now I don't use the crap out of it, atleast till now. Mostly it has been used for music with occasional sms/call. Rest of the time it is on. And it does seem as if it is capable of running music for hours interspersed over the day with a full battery charge. I don't talk much and just recently bought, so can't give too much details. But from what it seems, the battery is excellent atleast for me. It just takes several minutes to charge, and just do it 2-4times a day. A full charge officially should be 80minutes tho.
No issues with the swivel thingie, and it looks so SAXY. Just be careful while handling it cz build quality isn't dat spectacular and it could break.
There are 2 speakers and a earpiece. Headphones + Phone = Crap, worse than Ipod + Ipod headphones, stay clear off them. But wen used on mp3 player, the headphones ain't dat bad, maybe even better than ipod ones. bt i haven't realli used the headphones, so the breaken period mite nt yet be over.
Sound quality thru speakers is ok, bt nothing gr8. Not gr8 quality, bass is sort of bad, and it isn't very loud. Even on the roadside, it is better to hold it close to ur ears to get decent sound.
And I am talking of default software, things might be much better on other software.
