Charge the phone until the led light turns green. Then unplug, turn the power OFF (Don't just put it to sleep, power the phone off completely) then plug it in (the led light should now be red) charge until the light turns green again, probably like 10 or 20 minutes. Makes a big difference! I learned this in another thread but I can't find it now. Thanks to the original poster!
Update 1: I did this method again this morning 10am. It's now almost 11pm and I still have a 60% charge! I made several short phone calls, checked email, texts throughout the day, and took about 35 pics. I also spent a fair amount of time looking at them. Granted I wasn't on the phone as much as the first few obsessive days of owning this baby but still, I'm very happy with this battery trick.
Update 2: I want to add this quote by 'jasonb1985' from a different thread:
"if you take it off of the charger right as the light turns from orange to green then you'll actually have a full charge. if you let it charge overnight then you'll wake to a phone that quickly falls into the mid 90's."
I have to agree with this. Even with my charging method above, if you let it stay on the charger too long after it turns green for the second time, the battery level will quickly drop after removing it from the charger. I've found it's better to remove it around the 20/30 minute mark even if the light is still red rather than let it sit there and miss when it turns green. Of course the best case scenario is to take it off the charger the moment it turns green but that's not very practical.
One more thing I've noticed is that if you spend a lot of time in a location where there is little or no reception such as a hotel or basement etc, your battery will drop very fast. Best to put it in airplane mode in those situations if possible.

Yea I came here looking for that thread. This really does work. I tried it this morning and after I unplugged I was at 100% for the first hour or so. After my phone died at the end of the day today, I charged and after it turned green I unplugged and used it for 8 minutes and was down to 91% - So now I am charging it again and going to let it sit over night on the charger....I wish the was a permanent solution, I can't always hover the charger and unplug and plug it several times to ensure a full charge...
Thanks for testing that Bob. Too bad giving it a full charge with the method above isn't a permanent fix. Looks like I'm gonna keep "topping it off" each time I charge until they come up with a software fix or something.
I am a moderate to heavy user with this phone. I am not into all the disabling of the phone features to make it work. I use Wifi, GPS, etc whenever I need it and otherwise turn it off....I try to use it normally without thinking I need to always change something to get extra juice. Besides having to top off the battery a few times, this has been the best way to get that extra juice. I hope they come up with a fix soon or someone makes a "Battery Top-off App."

this didnt seem to work for me. i turned my phone off. but when i plugged it back in it immediatly turned itself on and turned the light green as soon as it was booted up.
The only way it works is if the phone is off...When it is on, the system is thinking the battery is at max. I think this could be a software glitch with the OS.

ok, this works for me if i leave it plugged in when i turn the phone off..(not unplug then replug in after it is off)
i don't think this is a bug in the OS i think that the phone uses energy while it is turned on and the charger does not provide enough power to both power the phone and charge the battery to a complete charge at the same time. if you found a smart charger that could provide more power than you might be able to charge the phone completely while it was turned on but you also might damage the charging circuit (i don't know enough about electronics to say for sure)
I'm using the battery indicator app. it tells you the battery voltage and temp and %.
at 100% my battery said 4.219V 81F then i turned off the phone. once the charging light turns green again i will turn it back on and add my new 100% voltage and temp to this post.
EDIT:
here is a link to a pdf that may be interesting to those who want to understand battery charging both for NiCd and Li-Ion http://www.national.com/appinfo/power/files/f7.pdf
fully charged li-ion batters according to this article should be between 4.15 and 4.25 v
that means that my battery before turning it off was in the higher end of that range.
the article states that anything above 4.25V will reduce the lifetime of the battery overall.
so if my battery tells me that it is above 4.25 i will no longer be turning my phone off during charging.
EDIT2:
ok i have just turned my phone back on. i let the light sit green for about 2 minutes before turning it back on.
my new amounts are 100% 78.4F and 4.108V. it looks like this process actually reduces the amount of charge you have once you turn your phone back on. after less than 30 secounds of sitting here i see my voltage has gone up to 4.22. i dont think this small difference is anything that you would see helping you get a further amount of use out of your phone during the day.
and i think that the article i linked to earlier will back up my personal numbers here if you take the time to read through it.

well im not lying, but i cant say for sure how good the app is at telling me stats on my battery...
thats the main thing im skeptical about.
although i do think that to get these readings it would have to pull the numbers from the firmware, so i wouldnt be too surprised if they were accurate.
This has worked for me. I wake up (phone powered off), unplug the phone and wait for the green indicator to go off, then I plug it back in till it turns green, and I repeat this a couple times each morning. Ideally I hope they fix this with a software update sometime.
I've been doing this for the past few days and it works great. I charge my phone while on overnight and then in the morning, while I am getting ready, I turn it off and let it finish charging.
While it's off though I unplug and plug it back in at least twice to get a complete full charge.
There is no need to unplug and replug it in several times. You also don't need to charge it on, though I can understand plenty of people will want to.
This is essentially the same as turning the phone off so that USB can charge it...the phone is eating some power while on, so when the battery starts getting near full, and begins to decrease the current, it eventually ends up sending all of the power to the phone instead, leaving the battery receiving 0 charge: which is the signal that the battery is fully charged. However, because the phone was actually taking a portion of that charge, the battery wasn't quite topped off.
This is why there won't be some software fix for this, or even a firmware update. It's been there on every phone, and Li-Ion powered device for awhile now...it's just getting to be more and more noticeable, as phones are able to use more of the power that should have gone to charging.
As for unplugging and replugging it in: It can take a moment for the phone to get a new reading on where the battery level is. It will assume that it actually needs to charge at first, and will try to while it figures out the batteries charge level. Sure, you are squeezing a little more in there, probably around the 1 percent mark...but you're also taking battery life off the top in the long run. Do that every day, and you'll be missing a nice chunk after a year. That 1 percent you are gaining, could be gone in far less.
Just charge it once with the phone off, and you are good to go.
Battery life has increased from 14 hours of heavy use up to 18 hours of heavy use with 30% battery left.
I find this hard to believe, since as it already has been set you would get around 1 or 2 more percent out of the phone by doing the above and killing the battery faster as the charges go on. An extra 4 hours under 'heavy' use would be around 25% more.
i'm confused...i have the oem tp2 1500mah battery in, and i just charged it to full and have had the phone off and charging for at least 45 minutes now and the light is still orange...
well, yesterday i got less than 8 hours on a full charge (with very heavy use mind you, but this is supposed to be a better battery than the stock one...no?) without doing the turn-off thing (just charged it til it hit 100%, then unplugged and went on my way).
it would have gotten even less than 8 hours, but once i got down to 20% or so i turned my brightness all the way down so the damn thing would last me til i got home...

If youve only had it for a w days it might still be calibration with the phone. I know the first 3 days i had mine I got less than 6 hours each charge. The first charge lasted me 3.5 hours roughly.
i have noticed this also , i just got my phone a few days ago. the 1st day it didnt last long at all before i had to charge it , and i had to charge it 4 times that first day , as time went on i have noticed that now it last way longer and its just the 4th day i have had it.. im new here and i enjoy reading all the post...
I am relatively sure the charging while turned off thing is an urban legend lol...i just did it and am getting no better battery life than I did without doing that...
I have no idea why it works, but this works for sure. It may be bad for the battery, I have no clue....BUT if you leave your phone on and charge until light is green, then turn it off completely and the light will turn orange for about 20 minutes, then when the light is green unplug it and plug it in again, it will turn orange for about 5-10 minutes. You can keep doing this a few times. When I do not charge my phone this way, my battery will drop 5% in the first 10 minutes it is unplugged and being used. When I do charge my phone this way, the battery will stay 100% full for at least 30-45 minutes.
I have tried:
A) Charge with phone on until green
B) Charge with phone on until green, then shut off phone and charge until green again
C) Charge with phone off until green
B & C seem to give the same battery life, both of which are better than A. However, A is the most convenient and gives me enough juice to get through the day, so I'm sticking with A .

I've found this exact thing. I turn it off and charge it when I go to bed, since I obviously wont be using it anyway, and turn it back on in the morning. The charge lasts me all day
This is quite interesting. I noticed for the first time the other day that when I turn the phone off after it is charged it will charge for another ~15 minutes or so before the led turns green again.
In order to get a full battery charge...
