During this time, I have used the phone for less than 5 minutes and sent less than 10 short emails. I haven't used any other functions.
My first assumption is that the battery is simply bad, and I am going to try to find a replacement (difficult here in Hong Kong since they don't sell the 8700 with the CS-2 battery yet), but wanted to see if others have experienced this or if there has been a known problem with the units themselves. That would be a real nightmare for me since it will be difficult to exchange the unit from here.
In the meantime, I'll try to condition the battery to see if it helps (not sure this works on Li-Ion models), but something tells me the batt is shot.
Eric, by any chance, is it difficult to remove the battery from its compartment? I ask because the first 8700 I received had a quirky battery level - it would show 70% one minute and 30% the next, even after charging it for hours. Moreover, I had to return that unit because it constantly rebooted itself every few minutes. It was only once I received the replacement unit that I realized that something weird was up with the first battery/compartment. I had to lever the battery out each time (my fingernails couldn't budge it) whereas the battery in my replacement pops out easily - as it should.
I still don't know the reason why my first 8700 was screwed up, but I suspect it was either a bad battery or more likely a bad "build," i.e. the battery compartment was too tight somehow and the battery wasn't making the proper contact to charge/power. It might be your battery (and I agree with you that "conditioning it" probably isn't the answer) but if you find the battery even remotely difficult to remove, you might just have a bad BB and should insist on an exchange. Hope this helps...
