So, how many times should you do "bump charge" cycles? And like I asked before, does it "fix" the battery, so that it'll last as long as a "bump charge" even when you just regularly charge it?
I got my Thunderbolt about five days ago, and I've only charged it about three times (the initial charge, a charge once it dropped to about 2/3 full, and then another charge this morning when it was only half full). For the most part, I've kept it set down to 3G, because whenever I set it up to 4G, the battery seemed to go faster. On 3G, it seemed like I could get through a day and only lose a sliver of the battery bar. On 4G, the battery would go down to a half bar on a single day's use.
This morning, though, I sort of "accidentally" bump charged it (haha, don't ask), and decided to leave 4G on all day, and to my surprise, only a sliver of the battery has drained. Pretty happy about that. Now I don't feel so paranoid about constantly making sure I switch down to 3G when 4G isn't an absolute necessity.
