I seem to have better battery life since the update -- 15 1/2 hours since unplugging with Wifi and GPS on, and I've got 68% left. I've used it sparingly today, but still not bad considering this is a typical day's use for me, and a far cry from the reports of 5 hour of battery life from a month ago.

Edit: 26 hours, 49% :)

Final Edit: 32 hours before it hit 14% and I panicked and decided to plug it in. The reason I lost 35% in those six hours is probably because I barely get a signal at work, so that accelerated the battery drain. Very impressed if HTC did some tweaks to increase battery life.
 
I am getting slow charge off my PC as well. But you know, I noticed last poster said the PC would run even less power to unrecognized device.

I just realized that when I mount my device it charges quicker than if it's just Charge Only. Strange since I always thought it would be the opposite. Hmm..
 
Well, the OP indicated he was already using the 1 amp wall charger, so it's not an amperage issue (assuming no hardware problems).

My battery normally takes 2-3 hours to charge from the wall, but I've got some weird battery consumption issues at the moment that I'm trying to narrow down that really make my charge time vary wildly. The only thing I can think of in your case would be to use JuicePlotter or System Monitor to check and see if any apps are using the CPU actively during charge. I noted on my phone that during the nearly-charged state and fully charged while on external power, my CPU will spike, often to 100%.
 
35 hours with 33% left.

Auto brightness on, full animations on.

30 minutes of youtube, texting, 1-2 hours of voice calls, checking email and surfing around the forums, taking a few pictures and a one minute video, used remotedroid for about 2 hours and searched around for a few apps on market/appbrain. Pretty damn good so far

Edit: 49 hours total until battery died.
 
So, I am a light user of this new Evo. I absolutely love the phone,.. but man.. the battery drains like 10 percent after being off the hook for 15 minutes.

I'd like to be a heavy user, but the ability to get my phone calls is way more important. Slightly bummed about the battery, but what can ya do?

I actually just got back from going to Sprint, telling this guy about my issue. He did the usual, tell me what to turn off, turned off a bunch of settings, deleted my clock widget, etc. And he deleted all my bookmarks !!! grrr.. He said that they take up way too much battery use, and went and deleted them without asking. heh.. Although he did give me a battery for free, i guess its made for the hero. But wish he didn't delete my bookmarks, lol.
 
Awesome battery life ;)

Unplugged today at 6:30am. Made 2 calls for approx 4 mins. Sent about 10 texts. Surfed/online for 35mins via wifi, and watched British Open Golf on SprintTV from 8-8:30a, 10:30a-1p, and 2-4:30p. At 4:30p, down to 10%. Not bad considering that's pretty heavy use.

Not bad. Not great, but not bad at all.
 
Yes the Hero battery is the same. the difference seems to be the color. the shape size and the part number is almost exactly the same. 35H00123-00M for the Hero and -22M for the EVO. Model #RHOD160 is the same as well.
 
I have 3 batterys and so far I have been averaging anywhere from 14 to 17 hours the way I use my phone.

Yesterday going into today is where my #2 battery as I have labeled them has turned out to be the work hourse of the 3 so far. Right now with the #2 battery I am at 1 day and 1 hour of usage with 47% battery life remaining. Now I dont try and save battery when I use my phone, I use it like I normally would here are the stats for it:

Cell Standby 42%
Phone Idle 28%
Android System 15%
Voice Calls 5%
Display 4%
Maps 5%
Dialer 2%
Camera 4%

Not much of an internet usuage day but I did check email quite often and shut 3G on/off when I dont use it.

I cant wait till Froyo is released and I root this baby!!!!!

Extremely happy with all 3 batterys so far. This phone kicks as*!!!!!
 
ok so ill charge my evo FULLY. then i will unplug it and it will be at 100%. ill make a quick phone call for like 4 minutes or say and i see the battery is drained to like 90% ALREADY. wtf is up with this.
 
Once the phone fully charges it starts running off the battery. Trick is to disconnect it right after it gets to 100.
 
For me (don't know about OP) it happens no matter where it's charged to. unplug at 99 it drops 10 or more percent rapidly.
 
Cell batteries need to be cycled/conditioned. Depending on how long you have had it, it should get better with more charges. Just got the evo yesterday and I experienced the same thing your talking about. Unplugged at 100 and after using the browser for no more than a minute, I lost a slice out of the battery icon.
 
You could try that charging trick. When you reah fully charged, turn off phone then charge until green. Then unplug and plug back in until green, repeat over and over.

i did that several times over a few days. had the battery tested at a sprint tech site store, says it's fine. i'm leaning towards something wrong with the way the phone reads the charge level. i've had it since june 19th, and keeps getting worse. i've ordered 2 new batteries and a charger, if they perform the same, i'm going to get warranty service.
 
Mine drops to 96% but after 96% it discharges very slowly. So no issue for me. Disconnect, recharge solution is too much work for me as my batteries last till night after the initial rapid discharge.

+1. Taking the phone off just as it hits 100 is key...mine will sit on 100% for 45 minutes with no use and will take much longer to get to 90% with moderate use this way...pulling it off after a night on the charger and I'm down to 88% or so within 20 minutes of use. I figure I'm truly starting at about 93 to 95% in those cases.

I'm in this camp. While I agree that the phone starts discharging while still on the charger, I think another issue is how the phone reads the battery level. I don't buy that it is that accurate. I only use the % remaining as a suggestion, but don't take any specific 1-10% drop as gospel. Regardless of how/when the battery appears to have discharged, I get roughly the same amount of time out of it every day.

i used to be able to say the same thing, except now it's been degrading steadily for some time. i've tried everything that common sense dictates to return it to reasonable performance, but nothing helps. i think it's the way it's reading, AND/OR an issue with the phone or memory card.
