After a full charge, unplugging causes it to drop battery %?

    I love my newest Godphone. There has been a few bugs suh as my wife sending texts not from her phone number, but from her simnumber. Of course the local store fixed it when the battery pull didn't work, and blamed it on a low battery. (40%, and they took it in the back. Dirty slappers.)

    Anyhow, mine is only presenting a battery reading problem. After a full night charge, unplugging it will cause it to drop wihin seconds to 99, 98, then 97%. I cannot keep it within the 90s after just sending a text message.

    Screen brightness is one step above dim, and the first thing I did was turn off sync, bluetooth, wifi, etc.

    I'm more confused than anythig st this point. Losing ten percent in less than three minutes of unplugging is damn odd. Is anyone else experiencing similar problems?

    The battery drain is a known issue with HTC. This is the same issue the Incredible had. The workaround that was recommended is as follows:

    Plug the phone in and charge it until the indicator light turns green (usually around 4-5 hours), then unplug it wait a minute, plug it back up until the light turns green again (about one hour), unplug it again and replug it up and charge again until the light turns green. After this unplug you should have a completely full charge and not see the immediate drop.

    I wonder if charging the phone while turned off ( I know, God forbid ) would make a difference.

    Unfortunately no. The Android OS is triggered to turn on when plugged up. About the only time the phone charges with it off is when it dies completely, but even then the minute you plug it up and it gets an ounce of juice it turnes on.

    The 1st thing I did when I got my Thunderbolt(ordered online), was to charge it. I just installed the battery, and plugged it in. It didn't trigger a boot; like my Droid would have.

    Well I do not know. Mine will not stay off when charging but I am following the recommendations I posted above and I am getting a full day with heavy use out of the battery.

    Let us know what you're doing and what you're using - truly. I'm not getting anywhere close to a full day of use, unfortunately, and I'm far from the only one.

    I just did the "battery bump" twice. Took the phone off the charger - 100%. Texted an SMS in low light. Now it's down to 95% 2 minutes later. The "bump" only works for so long. Yesterday I streamed video from Youtube for 10 minutes. I saw a drain of at least 15%.

    Yesterday (which was the first day after implementing the charging procedure listed) I had a one hour phone call with my mother, several other short calls, texts between me and my two daughters, ebay searches, forum postings, twitter and facebook. I was really using it hard to see what would happen cuz I don't usually use my phone so much in one day.

    This morning my phone has been unplugged now for two hours. I have gotten 28 emails, 56 twitter alerts, 4 text messages and was on the forums before I turned on my computer and I am still sitting at 99%

    I hope your battery indicator is telling you the truth, lol. I took the phone off the charger and made 1 text this morning. It dropped from 100 to 95%. Go figure.

    *** While knocking on wood*** I guess I have been one of those that have been very lucky. I only hope it continues otherwise I will get an extended battery or another battery to have on hand that I can switch out.

    I also am not in a 4g area nor am I even close to one. I understand that the 4g network is a battery hog and if you are close to a 4g network your phone is searching for it in the background which helps to kill the battery.

    One factor that affects battery time is how good your signal is. If you are in an area with weak signal the phone has to put out more power to hit the tower. This is regardless of talk time or just standby. (It is still handshaking with all of the services) If you are in a strong area the phone scales back to a much weaker output power and you get more battery life. Sometimes it can make a big difference. My wife and I noticed this big time with our feature phones when we stayed at a cabin for a weekend with next to no coverage. Our phones were using up battery charges like crazy.

    After exactly 2 hours unplugged, I did maybe 15 min of web browsing and 10txts and am down to 94%, not that great but also not as bad as some are experiencing.

    Also, I'm in north jersey so 24/7 4G signal.

    Unplugged for 1 hour - 6 mins of calls, about 20 texts. 84%. !!!!

    I did that special charging where you plug/unplug. Almost all syncing is off and brightness at 10% manual. Grrr. I might just get the extended because I can't have it die this quick.

    45% Display, 37% Voice Calls, 6% Cell Standby, 5% Phone Idle, 3% Android System. 2% Plugin Sample ????, 2% Market.
    1 hour 30 mins unplugged, 81% battery now (haven't done anything really). Losing like 5% per 30 mins just on standby.

    The extended seems like a nice option but that thing is HUGE! You'll need a backpack to carry your phone

    I think that would explain why your battery life has been as unique as anyone else's so far. I live ten minutes outside of New York. the speed of the phone and 4G data rate is phenomenal, but the phone itself does not last until the end of the day battery life wise.

    But I will try your bump method.

    Most Lithium Ion battery managers require at least one complete charge discharge cycle for the battery manager to be accurate. This needs to be re-done anytime you change battery capacity.

    This doesn't necessarily increase your battery capacity, but it makes the % remaining more accurate and enables battery management functions to run correctly.
