i bought my red 5800 last week.. i didnt encounter the earpiece problem for a few days until i read about it in a forum, and several days later it happened to me.. So i went to Nokia service center, they couldnt fixed it for another 2 weeks.. what phone am i supposed to use in the mean time? so i took back my phone and search for the solution online, and found a great video tutorial on fixing the earpiece, it took me less then 10 minutes to fix it and my earpiece is working well up until now.. then i got my firmware updated, it stops the phone from freeze and switching off automatically.. As for the battery, i thought my battery was defect, i charge the phone using my old nokia n82 charger and the battery didnt last for more than 6 hours after an onernight charge.. then i tried charging using the charger in the box, the battery lasted longer.. i used my phone heavily (emails, music video, musics, wifi,camera) and my battery last for a day and a half before i had to juice up again.. hope this will clear up some issues..
