It's difficult to determine the charge status of a lithium battery without counting mA in during the charge and mA out during usage ... (lithium charge transfer is surprisingly efficient.)
Er, my point is, yeah take note of how the gas gauge falls, because it's not a linear drop.

It may also depend on how offer you have your accounts sync with your device as well if you do not have anything running on the device. You can charge your battery the following way to see if that helps improve the battery life on your device.
1. Connect the phone to the charger and charge the device until the LED turned green with the phone powered ON 2. Disconnect the phone, and power it off. 3. Reconnect the phone to the charger, and charged the device until the LED turns green again. 4. Disconnect the phone, power it on, and then power it off. 5.

In the days prior I was getting about 4-5 hours of moderate use before my battery drained down to 40% on a stock Evo. I tried all of the battery saving tricks with little effect.
Then I installed ATK set to kill on screen off, Aggressive, with all my connected apps white listed. So, did it help any??
After 17 hours of moderate use including push email, IM, phone, Web, a bit of game play, etc, etc I was down to about 30% battery left.
To anyone who says that task killers don't help...well you are wrong

I've been using the EVO for a couple days now, and my battery life is ok. When I received the phone, it was at about 40-50% (I haven't downloaded any apps to show the actual percent). I used the phone for the first night to dran the battery down, then charged it overnight.
I haven't really changed much out of the box. I removed all the sprint widgets/shortcuts from the home screen (Sprint TV, NFL, NASCAR, etc), 4G & bluetooth off (I'm not in a 4G area), GPS & WIFI on. I've downloaded several apps (google voice, doubletwist, google earth, foursquare, bank of america, google sky map....etc).
Yesterday I took the phone off charger at 7:30 AM, did a bunch of web surfing, sent about 20 or so texts, used google navigation for the drive to/from work, sent & received about 20 emails, and the phone died sometime around 10 PM. I received the low battery warning around 7:30 PM, so it got a legit 12 hours of use. Not too bad.
As a point of comparison, I'm coming from an iPhone 3GS and the battery life is comparable. The iPhone is probably a little bit better if I'm totally honest.
Overall, my impression is that many of the battery life issues are being overblown. Well, maybe not overblown, but I don't know what people are doing to kill the battery so much. Regardless, perhaps the new versions of the phone are being better optimized by Sprint or something? Bottom line, the battery life seems to be acceptable for basic use.

really for me I have found that by just using the widget to turn off mobile data saves me the most on battery. In doing so you can still get text and calls but no internet and emails. This is bad for some, but I don't live or die by email. I used it this morning while golfing for example. I want the phone to receive calls and text but don't want to be bothered on the course with anything else. Also use it at work when I know I cant use the phone every minute anyways.
After 4 hours the battery was still at 91% I would hit the mobile widget during times when I wanted to check emails, twitter, FB etc and then turn it back off when done. My phone has been off the charger now for 9 hours. The mobile data has been turned back on for the last 3 hours since returning home and the battery is still at 63%.
Have ATK but have not used it at all today or the last few days. Just turned off mobile data

I also get terrible reception at my job and it was draining my battery like crazy trying to search for a stronger signal. I bring my USB cable with me to work and keep my Evo plugged up to my work computer.
im sure its been said already, but my BIGGEST battery saving gain was turning off "always on mobile data." I havent seen any negative effects after about 4-5 days of having that option turned off.
Today for the first time I have only used WiFi from the house (I work from home on Mondays) and while on WiFi all day (or since 8 this morning when I took it off the charger) I am still at 80% battery life vs when I was just pulling off the 3G, CDMA network. Now that is going to change when I am on the road all week and not with in sniffing distance of a WiFi connection but from my use today WiFi only I am getting a hell of a lot better battery life... Seems to me if you have the option of being locked into a WiFi network for a long period of time (home/work/any where) using just WiFi saves battery life.. When I left the house for an hour I turned the WiFi antenna off but other than that WOW... Amazed at the difference in battery life...
I just don't like having yet another thing to remember - turn wi-fi off when leaving home, turn it on when getting home. And doesn't turning off mobile data mean no texting, no web browsing?
In other news, I have found that removing the battery makes it last even LONGER!
Srsly, why get a mobile internet toy, and then disable it ...
Add the stock Power widget onto a home screen. One touch WiFi on/off (and gps, sync, bluetooth, brightness)
I've turned off "always on mobile data" as well and I haven't noticed any negative affects performance wise. I still get my emails pushed, and my weather widget still updates every 3 or 4 hours, as I had set it.
Just want to reiterate - i was a skeptic, but did a hard reset yesterday and it did WONDERS for me! There IS some issue going on with some people's phones. I literally was unable to get more than 6 hours out of my phone (optimized w/ nearly every tip I found on here - using it for maybe 15 minutes of the 6 hours off the charger). Today, it's been off the charger for 8+ w/ mild use and I still have 6 bars remaining on the battery.
There definitely are great tips to maximize battery life - but that's assuming something else isn't crippling it.

I have the weather and clock widgets which I know update frequently, but do the calendar, messaging and music apps tax battery life at all? They don't sync or anything, so I'm wondering if those are a big deal...

The battery life I'm getting is erratic to the point of bewildering. Last Monday, I ran from 100% to 20% in five hours, frequently manually running Advanced Task Killer to kill stuff. It was a PITA and didn't seem to have much effect. I switched to Automatic Task Killer and suddenly I was getting 10+ hours of use and I thought I was onto something.
Then over the weekend, I'd pull the phone off the charger and the readout from the Battery Indicator app (h/t Good & Evo) PLUNGED to 95% within minutes and was down to 90% withing a half-hour of web surfing on WiFi. WTFF?!?!? As I monitored actual use, it seemed to last an overall normal period of time (i.e. 10-12 hours) so I was wondering what was happened. Now it gets stranger, albeit awesome.
I pulled the phone off the charger last night at 12:30 am. I surfed about a half-hour and went to bed. Get up, go to work, do a moderate amount of email and surfing. It was a little less than normal, but then I watched a half-hour of the TWiT videocast on 3G, which is unusual. Other than turning off wifi and Bluetooth about halfway thru the day, I didn't to much to baby it. I just got the 10% alert, suggesting I get it on a charger...
TWENTY HOURS AFTER TAKING IT OFF THE CHARGER!!!
I don't get it. It acts like it's crashing in flames and then lasts almost an entire day. Very strange.

I noticed a huge difference too.....but my email stopped pushing in k-9, exchange, and gmail. No matter what I tried....
i deleted the battery % widget because i don't think the % are accurate on any of them. i stick with the broad default battery bar at the top. and guess what? i'm less stressed about the battery and not getting caught up in (wrong) minutiae. i don't need to track every % - especially when it's often wrong.
