So I ordered a battery that was suppose to be OEM and for the N900/x6/5800. I received it a couple of days ago, Hologram was of a different shading, battery looks exactly like the one on my N900. I charged it and began testing it yesterday. System check shows about 900mah on the battery. Today, it shows 1000mah. I assume that's normal. Something weird started to happen. If I reboot my phone, it would loop-reboot after the NOKIA screen. After 5 times, it boot through. I wasn't at home so I don't have my original battery. I would also constantly loses phone connection where I normally have full bars. Once I got home, put my original in, no more problems. Can the phone detect that this is a fake battery? Or is the fake battery causing problem for the phone? Should I just stop using that fake battery in case it explode and took my phone with it? Just thought I share this with you guys.
