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

[slinky]

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

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.

Thank you!
Time to try it!

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.
