Put me in the believer camp for the time being. It was driving me nuts that my battery would read 95% within a few minutes (if not immediately) after a full charge. After doing the procedure, it stayed at 100% for an hour on standby and after 8 hours, the last hour of which was active with email and surfing, it's at 82%. While it may not actually extend battery life, it's nice to have an accurate gas gauge.

Since this patch was updated last week I am consistantly getting 20-24hrs no prob on my phone now. No more scary thoughts of running out of battery till i get home.
I am very pleased now.
I still end a few stupid things I see hanging like camera and such and still keep GPS and 4G off unless I need them at the time, but this thing smokes now since the update.
I gave it a real test on Fri and took like 60 pictures and a few 720P vids and uploaded each one of those pics to FB on the fly with some other stuff. Worked great.

I simply take the phone off the charger for 5 - 10 minutes in the morning. It will drop down to 95%, then I just plug it back in. It takes 15 - 20 minutes to charge back to 100%, then I take off the charger and go about my day.
Less work than turning the phone off, etc, but seems to have pretty much the same effectiveness. ~30 minutes and the phone doesn't drop past 99%.

I do this everyday. It prevents the battery from dropping prematurely.
This works on a day to day basis but I did this before the battery calibration. It was the battery calibration that made my battery life improve.
I see peeps claiming 20 plus hours and that's what i want!!

Well, it appears that the steps are a one-day only deal, cuz after charging it last night, it promptly returned to its form of shedding a few percent immediately after getting off the juice. Tried the morning one-time boost posted above and it didn't appear to have much effect. After about 3 hours of almost constant surfing and texting, I'm at 57% and wondering if I'll get thru the work day.

I've had awesome battery life....I can pull 24 hours pretty regularly with 15 hours of heavy usage a norm...
but today I saw where some might be coming from....I was in an office with bad coverage....I was hitting 50% no-service based on the Android battery usage meter....and my battery suffered big time and I wasn't using it nearly like I do in a normal day.
I think this phone might be worse than average at signal hunting killing battery. Which would suck for some, luckily I'm hardly ever in that situation.

I think many of the problems that is being attributed to the EVO could be in part with the sprint network. It does kill the battery.
Though the EVO admittedly does have short battery life, I don't think it's as bad as some make it out to be.

so today was my first full day with the EVO and after a full night of charging, the battery app said that after 1hr and 25 minutes off the charger (its really been about 5 hours), and very very light use. just a bit of texting, a couple trips to the app store, and the usage of a few apps, almost no browsing, i'm down to 35% battery...that can't be good can it, or is that normal for just default factory settings?
since then i've tried taken off always on mobile, auto-sync and deleted all widgets but time and weather and now its back on the charger. i was just wondering if this battery life is normal for a first charge/default settings or if thats low even for that.
edit: the android system percentage was also at 50% which seems much much higher than everyone elses who has posted screen shots, any idea what the cause of that would be/if it is bad?

So, here is how I resolved this problem on my Evo. I leave the phone charging overnight (radio always on as I need to be available 24/7). In the morning I remove the charger and after 10-15 minutes connect the charger again and let it get back to green while I get ready for work. When I disconnect the charger my battery reports 100% and stays like that for over an hour most days. My battery life is quite good with normal use (moderate texting, few calls, hourly weather/mail updates, lots database and web searches) since I've been doing this. And yes, I do this daily when I work.
FYI, turning off always-on mobile data setting has been reported to cause random resets on some phones. I leave this and sync settings always turned on.

First of all if your in a building or area that has your phone constantly searching for signal, then your in for a rude awakening with Sprint, especially on certain phones. Turning off data roaming and selecting "sprint only" should help here, or turning off your 4g and wifi radios unless you need them.
The biggest battery saving tip of them all is to turn off background data and auto sync when your in those bad areas, or better yet whenever your not using them. Putting the Power widget on an area of your desktop helps.
There is a free program on the Android market that brings up sync settings in one click, which also enables you to turn off background data.
Another huge battery saver is to set the screen brightness one setting down from max, unless you need it bright. Turning off live wall papers helps too. And using a program like Astro to turn off alot of programs running in the background (you'll be suprised how many programs are running).
Why do you need to do all of this for Android phones?
Because of multi tasking. Its a double edged sword, that power users love, and novices don't understand.
One day Google will get this whole system running smoothly, until then there are still a few things that need to be done to get things running smoothly.
One of the biggest reasons that Apple sticks with AT&T and does not want to implement real mulittasking is because of battery life.
AT&T with their 2g network that cuts everybody off all the time, also has signal that penetrates buildings and thereby your phone is not left searching for signal forever (but you unfortunately get cut off alot because of that same fact). And their multi tasking is a large joke, having your IPHONE 4 crash because of true multitasking is not implemented.

< a week owner here and I must say:
1. Reading all this just made me paranoid about battery life; its not really that bad
2. The life has improved drastically over the past week
3. It last longer than my pre
4. I actually use the phone/features/keep network on and get a FULL day of life easily
5. Extended battery isn't even here yet
I love this phone.

I was also very paranoid about the battery life. In fact after I quit worrying about it and constantly checking it every time I turned around I actually got better battery life. The battery life isnt all that bad really. I can easily go an entire day with normal use and be perfectly fine. Plus once the new wears off the battery will be much better to. Its just like when you buy a new vehicle you want to drive it everywhere but after a few weeks its just another ride. Same thing will happen with the EVO in my case. Once the new wears off it will just be another tool with some very nice features that will be available to use if needed.

my battery life has been good since I got the phone from day 1. I've never had the phone less than 30% at the end of the day around 10-11pm.
I do agree there is an issue with the charge and how it drops fast, but even with that I still make it through a day with ease. Only things I turn off are GPS, 4G and Wifi (GPS and Wifi only come on when im going to use them 4G is always off since none in Orlando).

I did the batter calibration that was posted earlier in this thread and have had a significant increase in battery life since. So I'm a believer. Here are the steps for anyone who wants to try it:
To calibrate the battery...
With the phone in the on position.
Fully charge the battery with the phone on... (until the led turns green.)
Once the led turns green, unplug the charger until the led goes off.
After the led goes off, plug the charger back in. When the led turns green , power off the phone.
now.... with the phone fully powered off...
1. Unplug the charger.
2. Wait until led goes off.
3. Plug charger back in until the led turns green. When it turns green, unplug the charger again and go to step 1.
4. repeat steps 1 and 3, 10 times. This may take anywhere from 30 seconds to 30 mins per cycle. Typically only about 1 minute. though.

here. Yesterday I decided to *not* calibrate the battery as this root mentions great battery life, so I took it off the charger @ 7 Wed. morning. Before, even when I completed the calibration, under normal usage, I was less than 20% by the time I went to bed. After this root, as of this morning, with my normal amount of usage yesterday, I'm @ 36%, and this is after I turned some of the features back on (wifi always on now, higher screen brightness setting, constantly on vibrate, haptic feedback on). Like I mentioned, I haven't charged it since yesterday a.m. I'm going to see how long it lasts today, and tomorrow, I'm going to turn on one of the features I really liked, the live wallpaper.
