You could try charging the phone with the phone powered off. Gets rid of the need for a bump charge.
Not in my experience. Doesn't matter whether the phone is on or off -- I get the orange light through 4-5 disconnect, reconnect cycles. The only benefit that turning the phone appears to have is that the second cycle will be shorter, because the phone has not been on since the charge cycle prematurely stopped. If I charge overnight with the phone on, the second charge takes about 25 minutes. If I charge overnight with the phone off, the second cycle takes about 8 minutes. (weirdly, whether the phone is on or off, the second cycle takes a while, the third takes only a few minutes, then the fourth takes longer than the third -- e.g., if the phone is on all night, it goes something like 25-5-10-3-2-1).
OP: I've been "bump" charging since I got this phone 5 weeks ago, and I still have to disconnect, reconnect 5-6 times before it is fully charged. It is not the battery -- it is a problem with the firmware that controls the charging cycle and not the battery (the phone cuts off the charge to prevent overcharging, but it is doing so prematurely, before the battery is actually charged).
