Hello mrENigma,
If we start from the beging, first u have to get a battery as I told u before, a Nokia orginal battery and no b**** battery. We u get it so first time charging u have to charge the battery at least 15 h full time. Then u have to leve the phone on untill the battery finish by it self if u know what I meen. At the second time u charge the battery normaley untill the phone says it finish (normal charging) and LEAVE the phone on until the phone get off. U do the same charging again like the second one and aftet that u can charge the phone and shout it off as u like.
That was the "rule" about the new battey but remember u get the full effect when u have a nokia orignal battery.
For ur problem it sound to me that u have something strange in ur charger or the components around the charger contact in ur phone. If ur charge work for 100 % so I recomend u to go a nokia center to fix it for u cause it is very hard to check the componetns by it self if u know what I meen. Check the battery first I meen take ur battery to another phone and test, if u get the same problem u will know that the problem are the battery. Do the same for ur charger use it on another phone and test. And if all this test work 100 % i think that u have problem in ur phone so my friend go to nokia center to fix it for u.
<br />Good luck my friend and do not forget to tell me what happend <img src="smile.gif" border="0">
