OKAY. As many of you know, I used to be pissed about my battery life until I hit the gold mine with one of raven's 800 kernels. Even after trying 10 of them, only recently did one of them hit the spot for my phone. As most know, the higher the battery temperature, traditionally - the higher the battery drain. I noticed that most of the YouTube videos where people are showing off their N1s didn't have cases on their phones. Now, I regularly use two different cases: A seidio snap and one of the gel-like hard/flexible cases. Recently, I have been using the gel one. I also have a friend that I work with whose phone on the same setup and same kernel gets half the battery life that I do and she is using the snap right now. This morning, I flashed Raven's new 800 kernel AND switched my case to the Snap. If you saw my posts, I got roughly 35 hours of light-moderate use and still had 19% left a few days ago on his 800 from 5/04. After upgrading the kernel, my battery was better than stock, but not great (losing about 3%/hour). I just took off the Snap case and am flying naked right now and think I've already seen an increase in battery life. Obviously, it is too soon to tell. That being said, I'm a computer guy, not a physics guy and I don't know the thermodynamics of the material. I can say that the Seidio Snap has a felt lining and is plastic which I think traps more heat. You guys may tell me I'm nuts but I'm posting a poll to see. Now, I know everything is going to be a little subjective, especially the word "moderate"; however, I think most people contributing in the kernel threads have a solid understanding of the general consensus of the word. Sorry if the poll didn't include every option but I'm just curious.
<10 hour battery life is not crap. With moderate use that's what u get.

I considerate moderate use around 30 minutes total web browsing, 10-30 texts, <1 hr of phone usage and a few e-mails. Even the iPhone can go longer than that (and I hate the iPhone). Also, coming from someone now on 800AVS kernels that can finally get over a day, 10 hours is not very good.
I found the difference between nekkid and a rubber/felt case to be neglegable if any.
Conversely I found some apps to be bad about it when it comes to waking the phone for refreshing data or keeping the system awake (or more awake) even after the display is off. My biggest battery gains were in curtailing a few apps. ymmv, best of luck.
10 Hour moderate use is ok.
But i get double that...
Recently testing the GSM Auto (PRL) mod and it seems to boost my phone considerably.
Unhooked it yesterday at 8.00 PM went for my night shift.
At work i have used it for 20 min. Music and 20-25 min of surfing and nothing else. The rest of the time it has been on standby.
Is now almost 8.00 am. 12 hour has passed and is at 73% left discharging.
Here is my hacks and settings:
ROM: CyanogenMod 5.0.6-N1

Bluetooth, Wifi, GPS & Dataroaming are OFF at all times unless i need them
SYNC is constantly OFF always!!!
Brightness is at 1-13 %, and i just boost it if i need it.
Keep in mind im a light phone user. I mostly use my N1 for data service.

Honestly, I don't think kernel has anything to do with your battery life. At least not much.
I constantly PUSH 2 email accounts (never turn it off), I always have WiFi, BT, 3G and GPS on. I never turn them off. My brightness is at least at 75%, sometimes at 100%.
I constantly check up on Pocket Empires (game) for about 2-3 minutes every 1-2 hours.. do about 10 min calls.. check engadget, browse xda through an app a little..
And I get 10 hours. If I set brightness/sync like you, I'd probably get that battery life too. I got Cyan 5.x (latest), Amon recovery, stock kernel, stock radio.
I'm happy with my batt life, I can always swap to another battery that's always charged on the dock.. but I use the phone to its fullest and never have to wait for gps/mail/wifi.

Didn't think that I'd have to point out that iPhone has a 600MHz processor, 480x320 weak-ass screen and it only has 1 app running at a time?

I agree 100%. (Except I drive an Evo, not an STI)...
I get ~10 hours and that's just fine and as I would expect for this phone.
I am delighted that some people get more, but their experience is the exception, not the rule.
I have this phone and the Nexus one. I can't tell you for sure what real world use gets you, but here's what I found today.
I had a class to go to. I took my MT3GS with me to the class. I have the HTC Flip Clock, as well as twitter, my texts, GPS on and minimal use during the breaks, and Silent Time Pro keeping it silent. I got home and my phone was at 96%.
My Nexus was left at the house. It has Beautiful Widgets updating the weather every hour. It has no facebook, no twitter, nothing that will sync other than my email. GPS and WiFi were off, as was the display. The only thing running on the phone besides beautiful widgets was Silent Time Pro. When I got home, I checked my N1, and it had fallen to 69% with absolutely no usage while I was gone.
Like I said, I dunno what real world use would get you on the MT3GS, but it seems far superior to the N1 at this point. All things considered, I think the N1 even with the faster processor should have fared better, as it wasn't used and basically nothing was on, as opposed to the MT3GS having GPS, a few things syncing, a few texts, and more programs running in the background.
This (to me) either means that A) The MT3GS manages power better OR B) Beautiful Widgets takes up far to much processor and battery power. Maybe I'll test it on my MT3GS later this week when I have some time off and see.
Anyway, there's my opinion. Take it for what you will.
I'm running the HTC flip clock, a few toggle widgets, the FeedR widget, Taskiller widget, and a calendar widget, and from fully charged to the end of my work day (few songs, few youtube vids, some texting, browsing facebook, etc etc) by battery is at about 25 percent.
I hate to say it, but my old Motorola Cliq would play Pandora through my entire work shift and still leave me with as much or more battery life than the slide does.
Honestly, not impressed with battery life so far.
My battery life has been ok, not great, some facebook, some twitter, a few hundred texts. some interwebbing. I can get around 10-12 hours from a charge it seems. which in my opinion is crap lol. i had a rooted cliq before this that was running only the basics in the background(killed all the bloatware and extra crap), i could get almost 2 days outta that thing.
I thinks once we get root and kill all the bloat and stuff running in the background, battery life will go through the roof. A vanilla 2.1 or 2.2 will prolly do wonders for battery life.
just my 2 cents

I almost feel like raising my hand and calling bs on 2 days with the cliq'r but i dont know you.
the cliq i used would get about 10 hours with use and 19 or so without use.
my g1 would get about 9 - 18
the mytouch 10 - 18
the old garbage samsung flip and sony flip phones 2 - 3 days.
this slide im averaging 10 - 12 with heavy use and 17 - 19 without much use.
keep in mind only had it for 2 - 3 days since release date but i did drain the battery and recharge it a few times the first day to break it in.
so far id say its about average on battery life.
i charge overnight
then either while driving, or working
then i connect to pc at home
with a full battery in the morning
and a slight top off mid day i never run out of battery life.
Hehe with my cliq I only had only the essentials running(there's a few custom roms out). So it went for almost 2 days. You can get the roms off modmymoto forums if you wanna check em out. The key to the cliq is killing motoblur =). Pm me if you want info shadow
I'm happy with battery life. First day I played with a lot, browsed a bunch and installed many apps and got around 12 hours(most I'd ever get from G1). Today I'm going on almost 24, took it off the charger at 4am after letting it fully charge, didnt start using it till around 10am and at 10am the battery still read 100% which I thought was wrong. Right now its at 17% (still havent gotten the 15% warning) at 1:30am, I'm sure it'll make it till 4. Sent around 50 text today, installed around two apps, and didnt do much voice talking or browsing but I did at least a good 30 mins worth from both. I periodically kill all with advanced task manager (except sense).

Amen. I carry a 3 in. USB to Micro USB cord that charges me at home, in my car and at work.
Those that are disapponted by the battery life are being unrealistic with their expectations. Power is too easy to come by to waste time *****ing about it. Makes you look too lazy or good to plug it in.

I purchased mine yesterday,and it sat on the charger overnight, and read a full charge in the morning.
6 hours 42 minutes later, it gave me a "battery life is at 26%" warning. WiFi, bluetooth and GPS were all off (all day)
I have it setup to check my email and facebook, but I had my Kaiser doing that and more for 2 days at a time with a smaller battery...
Usage-
55% Display (was set to auto)
32% Voice calls (20m 21s)
9% cell standby (6h 44m 59s)
4% Phone Idle (5h 10m 4s)
This seems absurd! If tomorrow doesn't do better, I'm taking it back.

.Realistic ... I never expect an electrical device that CONSTINTLY draws power to have a great battery, I dont race my car all day or let it idle in my driveway and wonder why theres no gas in the tank. a battery holds a resorce that regardless if yo like it or not .. will deplete over time. Advanced task killer is a great tool to get rid of th7e programs rnning in th7e back grond. to save batt life.
.Sorry for any mispellings, my laptops keyboard is taking a crap on me after it got rained on last night.

I don't think my expectations were high. Most people outside our community think "only a day" is bad battery life. I expected to be able to make it through 1 day without going dead. Being 3/4 drained after only ~20 minutes of talk time is absurd, especially since I didn't use the web or IM, etc. Just POP3 email every 30 minutes, and I uploaded 4 or 5 photos to facebook.
No Wifi, bluetooth, or GPS...
I just wanted to come back and reply now that I've had a couple days to play with the phone. I've been using it for about 16 hours straight now, quite a few texts, 5-6 short phone calls, and maybe 20 minutes of 3G usage, I'm at 66%. I haven't had this phone on the charger at all.
On the other hand, my Nexus, which has been on the charger all except maybe 2 hours in that same amount of time is already at 88%.
I think we have a clear winner in the battery life category. At least from my tests.
I am certain now that I have a defective phone.
I killed all running tasks, manually logged out of all IM clinents, etc, and then took it off the charger. I've made 12 minutes of calls today, it's only been unplugged for 4 1/2 hours and it's at ~%60 battery life.
12 minutes? Thats got to be a defect.
But, they are apparently out of stock... I might end up with a Touch Pro 2 or a HD2 after all...
Definitely not right .. I'm at 85 percent since 9am (7pm now), light use again though but its stand-by time is impeccable.. try and get another one, I can tell you the HD2 battery life is much, much worse, my father got it at the same time I got the slide and he's charging 2x a day. Mind you this guy would go the entire day with bluetooth,wifi, and gps on his G1. Oh and the usability of windows, well its just blah.. not trying to be biased at all. I have my brightness at 30 percent, syncng gmail only, and for widgets I have the curvefish battery widget, pure calander widget, power widget, and audiomanger. No bluetooth, gps or wifi on.
Have you tried going into the about phone in settings, and seeing whats draining the battery (click battery use)? See what cell standby is. Are you using 3g? May I suggest downloading anycut > new shortcut, activity, phone info. From there, open the short cut and you can adjust if you want 3g only (wcdma) or edge (gsm) only. Try setting it at one of the only settings, your phone might be dropping and picking up signal.
First post here, Hello World!
I have had mind for almost a week now. At first I was averaging about 1/2 day on a full charge. This was with Gmail syncing, no WIFI/GPS/BT on. Mild surfing, about a dozen SMS and 15 minutes of talk time.
I installed Advanced Task Killer and set it to shut off my apps on screen close. I am now able to go 17 hours ( a full day for me ) and I still have 15% left. This was with BT on for about 30 minutes of talk time, WIFI on for about 1 hour at the office, GPS on for clock/weather updates every 3 hours.
Overall, I am happy with the battery life on this device now. I am wondering if it took a while for the battery to calibrate and ATK helping with running apps.
I love this phone!

Sounds about like me. I don't use my phone to call much (go figure) but I listened to 15 min. of music, logged onto facebook for 10 minutes (3g) and sent probably 15 texts, and I was at about 65% in the 5 hours I had it unplugged.

Here's a question, Did you all plug it in and let it charge to full when you got it BEFORE using it?
Sure did. Ive made that mistake before, but I do that with all phones now, even though with a lithium battery, it shouldn't make that much difference.

Yea, I guess im just superstitious but I always do that with a new device. Have you tried recalibrating the battery? Charge to full, leave plugged in for like an hour after it says it's fully charged, wipe battery status, reboot, use normally? (if you can wipe battery status int he menu's without root) I'm picking my MYT3G slide up this weekend so I don't know if it can be done or not yet.
i think the battery life is great, i take the phone off of the charger around 9am. while im at work from 11aM-7pM i check my updates every hr or so. from 2-330 i listen to music also on my way home(7-8) and when i finally get back home round 8ish my battery is at about 58% then around midnight i get the 30% message. around 130-2am its at about 12% so i get 17hrs with medium usage
My battery life isn't too bad. 17+ hours since unplugged of moderate use (but only like 1% left): Display 41% (on Auto), Wi-Fi 25% (worked at home, kept on wifi for data instead of 3G), Voice Calls 22% (35 minutes; 14 calls), Standby 8% and Idle 4%. I think if you're more active in process management, it will help with life. I also just switched Brightness from Auto to a manual setting of about 20%. I un-synced Tweet and Weather and am running very few widgets, but keep GPS on. My K9 Mail syncs on an hourly basis and Gmail with Calendar and Contacts auto-syncs. Overall, MUCH better than G1.
Hey guys I got my EVO in the mail on Thursday, and do I love the thing! I have been reading about battery life and was a little concerned at first, but that was then. Last night I unplugged my phone at 7pm and it had a 95% charge. I played with it a bit and texted until around 12am. I did not charge it and started texting and using it for a while this morning around 10am. It is now 4pm and I have 49% battery. If this is what everyone is complaining about, im happy with it haha.
Basically, it's people leaving 4G / Wifi / Bluetooth / GPS all on at the same time that kills the battery life of the Evo. My launch-day Evo has routinely done 20+ hours of usage with no problems.
The only times I've ever seen a marked decrease in battery performance, I could find that some app was hung up in the background draining the juice.
Rooted or just stock non root?

Come back after you try using data for an extended time (texts don't need data connections most of the time), having your mail sync for even every 3 hours or so and facebook, news, weather or any other auto sync feature enabled. Watch your battery die as quick as a witch under water.
My email syncs every 10 minutes, and my weather syncs as soon as it can. (not sure how many minutes). My facebook updates pretty often. And I have news updating as well.
My phone is also NOT rooted.
I get fine battery life, with WiFi connected I get much better standby than when using mobile data. Turn mobile data off when I'm out and about and the battery basically doesn't move. But I still can get 20 hours of use if I'm not on my phone constantly. I only turn off mobile data if I think I need my phone to last more than a day. Like camping or something. I have gmail pushed and weather and all that good stuff synced every hour. Been playing with juice defender which does increase battery life pretty good but you can get the same effect by toggling your mobile data with the widget. Juice defender does turn on data every 15 mins for a minute to sync which is nice but it causes a little lag when you unlock your screen because it turns on data as soon as you unlock, a little annoying.

I highly doubt this is possible especially on the stock battey. I personally know there is no way to have all those apps syncing at those frequencies on the stock battery and still get MORE than 9 hours of use. http://forum.xda-developers.com/showthread.php?t=783364
Unless you turned off your phone somewhere in that timeline and are not telling that bit of info. With the sync frequency you just gave, I seriously doubt your battery numbers are even the correct ones you're giving.

According to that, it says your phone has been powered on for 48 minutes and used for 15 minutes. Go back and check the link I gave in my first response and look at the screenshot most people would want to see.
EDIT: Saw your edit and your phone has been in standby most of the time. I personally am not impressed by standby times. But if that's what floats your boat then so be it. I personally have gotten 10 hours of CONSTANT use on the stock battery with apps syncing every hour and get 1.5 days normal use on my extended batteries.
i was able to get 7 days battery life with minimal usage as a simple phone:

Those are reasonable numbers and I have gotten that same use out of the stock battery. This phone is a joy to play with rather than letting it sleep all the time.

Yeah, I have gotten a whole 24 hours out of myn, but that was when it was new with little on it , and its first root and rom.
Sent from my netarchy_toast, froyo beast of a machine evo!
I know that people talk about losing the first 10% in like 10 minutes, but has anyone ever noticed how long it takes to lose the last 10% of the battery? That sht is frustrating, going from 90 to 70 for me takes only about an hour, but the last 10% for me can carry me another 3 hours or so. My battery is teasing me.
So I upgraded my Pre for the EVO when it came out and have been using the same phone and battery since getting it. I found XDA and immediately started rooting and flashing. I started with Fresh and DC when those were about the only options. I use my phone fairly heavily as I am almost always listening to downloaded radio shows either thru a plugged in headset or a jawbone icon BT set. I would say that I averaged about 8 hours of battery life no matter what ROM and kernel combo I tried. This is everything from Fresh, DC, Virus, Warm, CM6, EViO, Evo-NonSense, MIUI, and all of the applicable kernels. The best I had gotten with all of the various combos was a little over 16 hours (with an SBC kernel), which I thought was AWESOME! Needless to say, I used Warm TwoPointTwo (including betas) for a while and touted its look, feel, performance, ease of use, and feature set alongside an SBC kernel.
I ALWAYS keep an eye on the development section for something to pique my interest and pull me away from my current setup. After trolling Lucid's thread for cm7 for a while, I took the dive when the official cm7 nightlies started rolling out. I have been with cm7 ever since. I also took advantage of savage and zendroid kernels and now savaged zen.
The longest I have gone so far is 2 days 10 hours! How? Well...conservative governor on an SBC savaged zen kernel and toggling mobile data off when not in use. Will that same setup work for you? Maybe. Unfortunately all EVO' s are not created equal.
Moral of the story? It takes alot of time, reading, and work to find the thing that works for your EVO. It was a pain to find the right combo, but it is worth all the work.
Thanks for your post. When you got the battery to last over 2 days, it looks like the phone mostly sat there, am I seeing that incorrectly?
I, like you, have tried all different things with the Evo trying to get battery and performance. I am locked on MIUI right now, it gives me the best of both worlds. If you want to try a Sense rom, try Ava's stuff. When I get "bored" with MIUI I will go back to Ava.

God will kill a kitten if you switch from MIUI. You don't want that on your conscience now, do you?
Yeah it really depends on your usage without it the 2 days 10 hours don't mean much. 2 days is no problem if I only use it to make a couple of calls. every 8 hours it only loses 4% charge when untouched with autosync on. The evo battery isn't bad it just takes tweaking like the op says
I get on average two complete days on a charge. With heavy usage I het like a day and a half, with light usage I can go 3 days. MIUI 1.1.28 w/ savage 1.6 kernel. I used to shut off my data too when I wasn't using it but with the MIUI build I'm on, I don't need to.
I really don't trust the battery use(in settings) in CM7 at ALL. I had my phone plugged into my car charger for 45mins on the way home tonight I unplugged it at 7:38pm.
It is now two hours later(10pm) it is showing I have been unplugged for10h55m9s on the posted screenshot. Then if you look at the other screenshot my battery indicator pro is showing the correct amount of time since unplugged.
I've noticed that the battery stats in cm7 do not reset unless you fully charge your phone. Otherwise it continues the count even if you plug a charger in.

I get on average two complete days on a charge. With heavy usage I het like a day and a half, with light usage I can go 3 days. MIUI 1.1.28 w/ savage 1.6 kernel. I used to shut off my data too when I wasn't using it but with the MIUI build I'm on, I don't need to.

MetalHead, do you overclock/undervolt? If so, would you mind sharing your settings? Lastly, have you noticed an increase in browser speeds since you flashed MIUI and tweaked your settings?
I know I need to come up with something. my battery drain is friggin' horrid.
Unplug @ 100%, turn the screen on, let it sit with nothing, pretty much, running in the background and in 10 minutes will be down to about 93%....
Tried several different combos, but all are pretty much the same results...

I overclock at 1152 with smartass governor 98% of the time. Savage 1.6 is a HAVS kernel so I guess technically it is undervolted. I honestly couldn't tell you about the browser speeds, I've been on MIUI since the beginning of November so I really have no clue what the browser speed on a Sense ROM is. Everything is a lot faster with MIUI so I'm assuming my browser speeds have also increased.

This is typical, unless you use an SBC kernel, bump charge your phone, or unplug it exactly when the light turns green.
Any non-SBC kernel will not keep the phone at 100% charge while on the charger. Some will argue that doing so is dangerous for the battery or methods like bump charging put too much wear on the battery.
This is most likely the reason that phone companies rarely have a true percentage shown on their batteries, because they all do this. If we didnt mod to get that real number shown, you would think your phone was acting just fine.
Personally, if I am really going to be using my phone a ton in one day, Ill bump charge it, but otherwise I just accept that its going to drop that first 10% really fast.
The best measure imo of battery performance is how much % you lose when the battery is somewhat discharged, and off. Every phone will drain while you use it, but most of the hours of a day, your phone is off and idle. If you lose 1% per hour, or 5% per hour, that will make a huge difference in your up time per charge.
Unfortunately, mine doesn't stop at that 10%. For instance, mine came off the charger at 5:30 AM at 100%.
By Noon, it was down to 70%, and I had 1 - 3 minute call, no texts and maybe 20 minutes of playing Klondike before work.
I guess I'm gonna have to go SBC. Worst that can happen is I end up buying a new battery, just incase it does so it in.
So in 10 minutes you drop 7%, and in the next 6 1/3 hours you drop another 23% with moderate use?
That sounds like pretty typical battery results to me, thats about 26 hours uptime with a fair amount of use. But maybe others could chime in.
Dude, 5 hands of a card game is NOT moderate use. It's practically no use. Klondike doesn't use data, GPS, etc... nothing, except minimal graphics.
The one phone call literally lasted less than 5 mins, so yes, a phone that drops 30% doing nothing is drastic.
I seem to get pretty good battery life on Myns rom.
I can go at least 24 hours with moderate usage, all on the stock kernel.
Looks like I may have found a little better stability with the Netarchy-Toast CFS 4.3.2 Havs SBC less.
30 minutes of moderate use today and it only dropped 5%
The best battery life I have gotten is from Feb 09 Plutonium.
Miks 4.5 4.2 sbc, gps on updating all every hour call, text, surf, angry birds all freaking day, and get 14 to 16hours every day
MIUI
Wow i have been wanting to try MIUI for a while and i definitely will now.
I'm getting pretty bad battery life with MIUI 2.11 on hw 003. Can anyone recommend a good kernel? I'm hesitant to try the SBC kernels based on the potential battery damage, so savaged-zen is out, also savage-zen seems to have issues with usb mounting.
Is there a link to savage 1.6 CFS, which I've read in a number of threads now is a good one. Speed is not imp, stability, bt+usb working and battery life is.
battery life.... that's really about it. htc really dropped the ball when it came to that. i have never been able to achieve decent battery life, even on custom kernels.
what about you guys?
I have no issues whatsoever. I get about 12-16 hours on a stock rooted EVO. I also have an extra Hero battery that I can pop in my back pocket if need be.
Simply love this phone
really, bad battery life, because i use Vaelpak with netarchy 4.2.2cfs havs less and i get a fulll day with normal to a little heavy usage, and on light days y get like 30 hours, by light i mean checking my email 3 times a day, facebook also 3 times a day a few minutes worth of call and couple dozen texts, also a few online searches on sports schedules and so. so i dont know how some people still say battery sucks. any how my dislike is probably my evo doesnt have my coffee ready when it wakes me up

most of us have no idea how some of you achieve the 30+ hr battery life. even with a 2000mAh battery & sbc i get no where near that.
couldn't really point it out, you know with this my final set up i wiped, installed rom, booted, wiped, erased battery stats, flash kernel, boot, set cpu profiles, turn mobile data always on to off used the 3g tweak where you go into ##3282# and changed the last prl to 0 and 0.0.0.0, turn my screen brightness down use launcher pro, and after doing all this i let my phone discharge till it hit 15% and charged to full did this the next 3 charge cycles, and after testing it for a week i realized that if i didnt use my phone it would only drop 1% every 2 hours and when i was using it it would drop about 1% every 5 minutes

Well, that's because most of us don't use the Evo to play 3D games that push the GPU to the limit, watch Sportscenter using the Slingplayer while you're at work, constantly flash different things just to see what they do or it looks like, HDMI mirroring, etc. If all I did was check my emails a few times a day and send out a few texts, my phone would last 30 hours, too. During off peak hours that my phone isn't constantly syncing and I'm asleep, it will go down from 100% to maybe 92% overnight. The thing is, I never put it down during the day so I (and people like me) have to keep it on the charger at all times or keep extra batteries. I do both. lol
Asides from that, my only complaints include the annoying pop-up window that comes up with the OEM verison of Swype. I also wish that Sense had landscape support for the home screen and that the camera wouldn't take 5 seconds to focus and shoot. But the pros greatly outweight the cons IMO.
Yes on stock battery with juice defender and sbc i get 15-16 hours with normal use.. less if I play a game or 2. Really have nothing bad to say about the evo
from my phone duh
To be honest, I've had sooo many phones and id have to say the evo is hands down my favorite phone ever. I will say its hard to say what I dislike because this phone literally does EVERYTHING. I don't expect battery life to be amazing given it has a 4" screen but if I had to choose id say the power/volume buttons. HTC could have done a better job on the quality; being a rom flasher tears these buttons a new one.

I don't believe these claims for 1 minute..... with your heavy or "Light" usage.
Checking email 3 times a day, it's a smartphone(should be able to check emails when you want), should be able to check facebook when you want. To make calls when you want and not worry about your phone being dead in 4 hours.
The EVO is still my favorite phone to date, I buy a new smartphone every 12 months when allowed...
I have so many different roms/kernels and give them a few days to settle down. I have try the battery conditioning tips, etc..... There is no way, unless your barely using your smartphone that ANYONE get's that good of battery.
I sync my emails every 2 hours, facebook every 2 hours, have weatherbug synced, tweetcaster(twitter) 15 minutes and my 2 games of wordsmith and wordfeud.
I did a test last night, charged my phone to 100%, turned wifi on and set my phone on my night stand all 11pm. I woke up at 9am and my batter way down to 24%. I had many missed notifications, text, emails, game moves, etc..... That much of a drain with wifi on and on standby is crazy!
I will be getting the nexus 4g and then the EVO 3D, I hope one of those phones batteries will be improved than the EVO 4G.

Believe it. I can get about 40 hours on my phone with light usage. 20-30 texts a day, 2-3 times checking facebook, and a few emails sent and received all day. I can get this with Myn's 2.2 rom, and with using Setcpu to gradually scale the cpu down as the battery goes down.
ANd I probably could go 48 hours if I was on wifi and not 3g.

I agree at first that battery life was less then spectacular. But after rooting and using custom Roms as well as setcpu my battery life is very good. I would consider myself a moderate user (50 -60 emails, 40-50 texts, 20-30 calls, some internet searches etc) and my battery after unplugging at 7am and getting home at 6pm is still 50-60%.
I have to say that I am disappointed with the camera, low light shots/making videos isn't as good as some of the other phones out there. I was looking forward to the camera when I got the device, and it took such good pictures in the store - it hasn't been that horrible using it or anything, I have gotten some good pics and all, but these days I usually have to take 5 pictures to get one good shot.
I can't stand the ****ty speakerphone. I use it every day while driving and I have to lay the phone on my chest to hear the person. If the Evo 3Ds speakerphone is this ****ty they better toss in a bra with the phone purchase.

love the phone, but I've had it replaced twice (thanks insurance) for build quality issues, light leak, screen splotches, cracked buttons, etc.
Battery life has been horrible since day 1 (bought on release date), but 2 spare batteries gets me through the day.
The cameras are great, but the FFC sucks without bright lighting, and the rear cam is great until it's pitch black out. Also for video it's not the best.
Kickstand is awesome but unstable at times
it wasn't free? lol I don't know what else to say it's my favorite phone I've ever owned so far!

You battery should have been above 90%, and you shouldn't have missed any notifications.
Your phone is obviously defective.
i wish this screen would show detailed, but my phone only shows system as a whole, haven't looked for a more detailed way, don't really need it as dont need to prove my battery stats to none
I can't really say that the battery is an issue with mine. I almost never use wifi, have gps on all the time. Sync twitter, weather and gmail, and play at least 2 Wordwise games a day. I take the phone off of the charger at about 8:00 AM and it lasts until I put it back on around 12:00 PM. If I play two or three hours of games it won't make it that long, but neither will any other smartphone that I have used.
My only disappointments with this phone are, the mediocre camera, the lack of internal memory, and Sprints crappy data speeds. I have had mine since launch day and have only replaced one speaker that went bad, other than that it has worked flawlessly.
CAMERA SUCKS. 5mp iPhone camera mops the floor with the POS camera on the Evo. Evo is still a better phone, but my god, the camera blows.
My complaints are that HTC doesn't like us very much anymore and that hardware isn't user upgradeable lol. The first one doesn't matter since we have xda, and the second industry is just unrealistic lol. But my battery life is normal, get about 9 hours per battery which is fine since I have 2.
