    I have the 2150 battery from verizon.. one thing I've noticed.. when you charge the battery overnight AFTER having powered off the device.. it gives you MUCH better longevity than when you charge it by simply plugging the phone to the charger..

    Try this and I am sure you'll notice the difference.

    So what you're saying is, that when you charge the battery, in your phone, with the Phone OFF, you get a better charge than if the phone was on.

    People are referrign to this as a charge bump.

    Oddly enough, I noticed the voltage on the battery go from 4.13v (regular phone ON charged) and then 20 minutes later (phone off charging) the battery went to 4.15 volts.

    Certainly interesting.

    yes, it's interesting.. usually even when I am on standby (note, my gps and bluetooth are always on).. my charge drops a good 10-15% over 6 hours.. when I did this.. it dropped by 1 percent after 6 hours!

    I am on day 2 after charging this way.. and after heavy gps navigation use the first day I am on 53% charge. Just the day before I charged it without powering off and my charge dropped like 30% in a couple of hours of usage.

    I use my phone as an alarm clock so thats a no-go for me :(.

    I sure hope HTC fixes this issue in the next update.

    I am leaning towards this NOT being a bug. But we can hope.

    As somebody noted on the Evo board, our phones will NOT trickle charge when they hit 100% and are on. They will begin running on battery, and then pick up charging again at a certain level. The bug here is two-fold:
    1) The charging indicator should be showing when it is doing a refresh charge
    2) The phone should trickle charge at 100%, and not use battery until unplugged again.

    That is the reason why the "bump" charge works - with the phone off, there is no power use, so you get the full effect of the charge.

    There is something wrong with the stock battery, so I have to agree.

    I spent some time with a battery that came out of a 2 month old TP2. The battery was so much better it is sad. As soon as I put my 1300mAh back in, I saw the difference. With the same usage or in some cases lack of usage the two different batteries are lightyears apart. I don't wanna take the phone to the store, because they normally won't just swap out batteries.

    This battery is mostly unacceptable and regardless of all of the tips and tricks that require neutering your phone, they don't help that much. After seeing the terribly looking battery from Verizon with the new back, I am just gonna have to suck it up and get a 1750mAh. I would have just paid an extra 50 bucks for the phone if the battery had been up to snuff.

    I've been using the 1500 mAh OEM battery and, while it IS better than the stock 1300, I only got about 7.5 hours of moderate use today (yes, I did bump charge before I started using it).

    So, I'm unsure if having two 1500 OEMs will be the way to go versus a single 2150 mAh battery. I have the 2150, don't like the hunchback, but I think the 2150 will last longer than two 1500s. I was going to give back the 2150 and just get one more 1500 (but really, I have the stock 1300 and a 3rd party 1600, so should I spend money on another 1500?) AND either the Seidio multifunction charger or the Innocase Active (one battery plus one accessory = cost of 2150 battery after 25% discount).

    I don't know what I will do. I do love my hard silicone case and how slim my phone is. I dropped my phone today on the street (fell out of pocket) but the hard silicone case was on and protected it just fine. I know if the phone was bare and had the 2150 battery, I would not have been so lucky.

    A little off-topic: I don't think battery discharge is linear; I think discharge is slower at the higher end of the capacity (e.g. from 100 down to 75%) then accelerates as you go lower.

    I don't think the phone can "never" use the battery, I would bet that if you removed the battery while plugged in, although the phone would remain on, the radio ckt would be starved for power and possibly fail.

    The radio ckt needs that "reservoir" of the battery to handle the spikes in current draw. thats my opinion of whats going on there.
