When I was looking up info for the G2 I always read about battery life in percentages and comparisons against other phones/batteries. I wanted specifics of how the battery was used. I wanted to know if it was worth upgrading the battery. I knew that the G1 has horrible battery life. It was so bad for me, I even went out and bought the seidio big battery, the one that has its own custom battery cover. That thing made it look like a brick and everyone commented how huge and heavy it was. It wasn't all bad, as they loved the keyboard =)
I looked down at my G2 just now and it had the empty battery blinking with the redslash. Because of my experiences with the G1, I was ready for the G2. I have 3 seperate charging/usb cables: at home, in my car, and my workplace. Is that paranoid? I just knew that with my G1, it sucked being without a phone in the late afternoon. Just now I realized I hadn't charged my G2 all day. I looked up the battery info since last unplugged today.
14:55:38 hh:mm:ss
I couldn't believe it. I use my phone pretty well throughout the day.
Here are the details of my phone usage with the stock battery. I've had the phone awhile now, so I dont abuse it nearly as much as I used too.
Stock ROM
Ota Update
Temproot via Visionary
Overclocked to 1017Mhz
Tasker: 1 task for gps using all apps that need it (maps, sky map, etc)(I should probably use this more)
Email/Texting about 10/hr throughout the day
Brightness on auto till 4:00pm, after that it was set to 20%
Wireless on for 4 hours
Bluetooth on all day
4 games of sudoku (about 10 mins each)
2 full levels of defensoid
4 hours listening to music/listen streaming application (on the road into and out of work, yea really long commute, 2nd shift)
2 hours of talk time
Tesla Led for about 10 mins
Maps looking up an alternate route in traffic
AndroidAlarm task running all day
Christmas shopping for about an hour in browser.
Surfing reddit for fun for about an hour
Reading through the black ops app guide again (trying to figure out the perfect load out) =)
A couple of other apps, but not more then a few mins each.
I'm in a HSPA+ zone 95% of the day.
profile for SetCPU plz?
and btw that's insane
I dont use a profile with setcpu. I just start it after root and then move the 1st slider all the way up. I used to have a problem with keeping the OC at whatever I was OCing too at the time. I used a profile back then. But then after switching out my sim card and the OTA, I don't have an issue with keeping the OC at 1017MHz. I would constantly use linpack to make sure the OC was working, only because it was faster then running a full quadrant.
I did notice my battery get substantial hotter after the OTA using val=(anything above 62), so thats why I just stayed at 1017Mhz.
I got my chichitec red batteries and love em so far right now i have my g2 since unplugged im at 1 d 1 hr 54 min and its still at 60 percent modertae web searching and phone calls throughout the day oced to 1497 mhz with set cpu profiles
Hoping to get some good feedback from those who have used the epic for a couple months or more. Now that you're probably using the device normally, as in not attached to it all the time, how is battery life? I've heard initial reports that it's not so good... Also, for those of you who have updated unofficially to Froyo, does the upgrade help with battery life? Can anyone comment how Epic's battery compares to EVO's?
Thanks.
I usually get about 9 hours in my stock battery and 6-7 on my cheap eBay ones. Overall idea say meh, its about on par with most other android devices. I'm running the stock dk28 leak as well with no battery tweaks or mangers of any sort.

On most of the DK28 roms I'm pulling a solid 10 hours with moderate use. For reference, If I leave the phone on standby all day in my house it's lasted 23 hours, if I recall correctly. Honestly that's pretty damn good for a smartphone.
EDIT: I don't use any battery-manager or powersaver either. Brightness = Auto, bluetooth/wifi/4g/gps = 1 is on at any given point in time usually. Google auto-sync = on as well as touiteur (twitter) and facebook notifications every 15 min.
I have been impressed by my battery life actually. I can't speak for the EVO(although maybe soon since my friend might give me his as a backup). I can usually get between 4-5 hours of play time(surfing, texting, apps, music, wireless tethering, movies, etc) The rest of the time it is usually idol. I usually charge it over night, unplug it around 7am, then plug it back in around 11pm. At 11pm, I usually have between 10- 30% battery left.
I just switched to a froyo ROM(bonsai, which is excellent) and so far the battery seems to be about the same. By lunchtime 12:30 it is usually between 70-80% and right now I am at 72% but I also had some extensive time testing the tethering feature.
To be honest, I had a blackberry, and the battery life was a little better, but the features were not nearly as good. It amazes me the battery these things get with that amazing samoled screen.
disclaimer: I do not play games outside of sudoku and spades, so my CPU does not really get challenged, which probably accounts for some battery savings. Oh and I use regular wallpapers, cause I don't really like the live wallpapers.
Im on 2.2.1,and I have to say I see a 40% increase in battery life compared to 2.1,and thats about 11-12 hours,no battery saving apps either,well except setcpu,which does help,but its set at 100mhz - 1ghz conservative.And I use it more now then when I got it,I havnt got tired of it at all.I have noticed the first 10% goes the fastest,and I have calibrated twice since moving to the ROM im on,and its the same in all,so if you get an Epic dont let that scare you.

I've had an Epic since a couple weeks after it was released and I think the battery is probably working the way they meant it to, which means a solid day. I charge it overnight, unplug it when I go to work, plug it in when I go to bed, and I'm usually at around 40% by that time with moderate use. I don't generally have problems with battery drain.
The exception to this is when using GPS with the screen on. It's really difficult to use this phone as a direct PND replacement even though it's basically made for it (especially with Froyo, which fixes the GPS lock issues), because the screen and GPS together will drain the battery from 100% to 0% in about 40 minutes. My dedicated PND, by contrast, will give me 8 *hours* of continuous use on battery power.
Also, I have a 1000mah car charger and even with that connected, the battery still drains when using GPS and the screen (it just drains slower). I have to just turn the screen off when I know I won't be needing to make a turn for a while.
The one thing I wish about the Epic is that it had a regular old LCD screen. The AMOLED screen is the one battery killer - you really need to watch how long you have it on. In normal use it isn't much of an issue, but you just can't do much of all the cool things they advertise that you can do with this phone (like GPS or watching movies).
I do also keep my screen turned way down, which makes a difference, but it's still a killer.
Well, I reported over in another thread that with Froyo, and basically having my phone sit around and do nothing with no WiFi, GPS, Bluetooth, no "fixes" such as switching to airplane mode or killing the DRM service, and no "battery saver" programs, I was able to get 108 hours on a single charge with the stock battery (1500mAH). That was with the screen on time of about 50 minutes and talk time of about 40 minutes... (pictures here)
It all boils down to how you use your phone, but in a stock configuration, the power management seems to be better on 2.2 than 2.1 as shown by the large amount of "idle" time I was able to get on a single charge.

I don't disbelieve that - in my post above, when I'm talking about draining the battery with GPS and the screen on in 40 minutes, or when I'm talking about having 40% battery left at the end of a regular day, it's almost always with a screen on time of 30-40 minutes. So 50 minutes sounds about right to drain the battery completely, with nothing else on.
I'll bet if you had 0 minutes screen on time - just let the phone sit idle - you could have probably gotten 200 hours or more.

LOL, what's the point of having a phone then? 8-9 days without using it? I dont think I could hold out that long.
And I didn't even see your post until after I posted.

No I know, I was more just clarifying so it didn't seem like we contradicted each other. I think the important stat is really screen time and then any extra radios you have turned on. Just with the regular radio and nothing else, you could get ridiculous battery life on the Epic. It's the extra radios and screen that kill it.
My phone gets me through the day. About 20% down in 7 hours on standby, so thats decent. Heavy usage with full brightness on and live wallpaper starting in the morning, stopping at like 6 A.M...it'd probably die there, for me at least.
The battery is good; I'm running the dk28 rom but it really hasn't affected my battery life at all.
On phoenix kernel i was getting 20-36 hours moderate to light usage. With acs xtreme kernel I'm getting 12-20 hrs w/ moderate use.
That's about 3-4 hrs of screen on time, 45-60 min of talk time. Emails, text ing, twitter, xda, and some various forum reading. Angry birds if waiting in line somewhere..
Note: I leave background data turned off and manually sync/refresh mail/contacts/data. I have no need/desire to be alerted evrytime someone updates twit/fb. I also use juice defender.

I can barely look at my phone on full brightness - it hurts my eyes with beams of awesome.
I get between 13 and 16 hours depending on how much Angry Bird time I put in that day. If I'm doing normal browsing, facebooking, etc then I'll be closer to 16, but gaming drops my battery like a rock.
Thanks for the replies! I think I'm convinced a lot of it has to do with how you use the device. Pretty much how it went with the EVO when it first came out... lots of people complaining about battery and then it kind of faded once everyone settled down. All I need is to get from early morning to right before bed.
GPS with google nav is a killer on any Android with decent screen size and resolution I think. Anyway, I thought SAMOLED is supposed to save a little battery? Or is that only if the background is black? In any case, I usually dim my screen to 30%, keep GPS off, keep auto-updates down to a manageable size, and use some other tricks to save battery, so I should be good to go.
I tried to thank all of you with the new thanks button, but didn't realize there's a limit per day haha. I'll finish it up tomorrow.
As far as I am concerned the battery life on DK28 is amazing. I use overclock widget set at 1000/200 screen on and 400/200 screen off. I can pull more than 30 hours with multiple phone calls, texting, email, web and games for over an hour. Here's the screen shot I took today before putting the phone on the charger.
I've noticed a substantial improvement in battery life since upgrading to 2.2. However, I also began using the Epic Experience ROM shortly afterwards, which boosted it even further. That, plus Juice Defender nets me a perfectly acceptable battery life.
I used my phone heavily today and still got about 18 hours out of it before plugging it in before bed at a 35% charge. On top of that, my phone's never felt snappier.
whoa, is it normal for the epic to take 3.5 hours to charge? If so, any explanation? Past devices i've had tend to take an hour less... Running 2.1, does Froyo help?
Currently on Epic Experience with SuperPower installed. I unplugged the phone about 16 hours ago and it's sitting at 36% with light voice and moderate SMS/data use.
Battery life definitely improved after upgrading from 2.1, even with light use it would be dead in under 12 hours on stock 2.1/DI17.
How to get unbelievable battery life
I have some very VERY helpful hints of great battery life for the Epic 4g. (as i am on hour 26 to 28 and have 20% left with about 1 to 1.5 hours of screen on use.)
First off, use black, or almost black background. Our screens are superAMOLED. This means that if the screen is showing black... those particular black pixels... are simply not on. If you have the home screen black, and have no icons on it, then the status bar is all that is using power... maybe 6 or 8 percent.
Next, Lose the brightness. A few helpful hints on this. 1) uncheck the autobrightness in the display settings 2) turn the brightness down in the display settings 3) If you slide your finger from right to left across the status bar at the top, the screen will dim, if you slide your finger from left to right, it will brighten(this causes accidental brightness 4) cover this light sensor on the right side at the top (I believe) because the phone seems to have a problem always autobrighting even with the uncheck in the settings. This is done best with electrical tape, or perhaps finger nail polish. These things should ensure to always be at minimum brightness
Next, Install Frankenstein Froyo Rom(lightest rom=less cpu usage/blackest rom=less screen battery usage), And Genocide Kernel(undervolted)
Next, install task killer(keeps the rom at optimum efficiency meaning less cpu usage assuming you are killing the apps 3 or 4 times a day) install set cpu(This allows you to limit the cpu clock speed(400mhz is optimal usable and battery settings)
Things to remember, ALWAYS TURN THE SCREEN OFF.
If you pick it up every thirty seconds to see if you have a text, then just sit it down... whats happening now.. The screen is staying on for another 15 seconds probably. DUH!!! bye bye battery!!
TURN OFF THE SCREEN BEFORE YOU SIT THE PHONE DOWN!!!
Turn off gps when not in use.
Turn off wifi when not in use.
Turn off 4g when not in use
Dont use it as an mp3 player.
Dont talk on speaker phone.
Those last few were pretty obvious.. but some people need to be told.
I Hope this helps anyone looking to conserve battery. Follow these steps and i promise 24 hours plus ever time and often as much as 48 hours.
Enjoy
EDIT****
By the way, When you set yourself up with this rom, you are making your phone TWICE as fast... LITERALLY. Hard to believe that a ROM could be twice as fast.
With stock android2.1 this phone gets 800 to 900 in quadrant(benchmark tool/tell how fast your phone REALLY is) Stock android 2.2 quadrant score is a little better scoring as high as 1000.
With this setup, i have gotten as high as 1950 in quadrant. No joke. This is reflected as you cant even tell the phone is clocked down to 400mhz without heavy apps and REALLY paying attention.
I used to get about 8 hrs of use before having to charge. Battery would drain even when I wasn't using the phone. Since flashing to DI18 a few months ago battery life has been great. A good 15-17 hours of moderate/high use and minimal drain with the phone on standby.
I lower the brightness all the way, end the DRM process and do the TWS trick after a reboot. No fancy battery management app that disables all your phone for the sake of battery.
I expect 2 hrs of the screen being on before my battery gets down to 20-30%. Which I think is very reasonable for moderate to high usage.
In the interest of branching out of the main thread, I thought I'd start a thread regarding battery life- how many hours are you guys getting? For those who have somewhat decent battery life, what tweaks/settings are you using?
I went and disabled background data syncing hoping this would at least help improve battery life only to find that even idle (with no real use at all), this thing eats battery like there is no tomorrow.
I think with super light usage the most I've gotten is about 4-5 hours. There HAS to be a way to improve on this. I can never walk around without my charger in my bag- that is just crazy.
So any ideas or suggestions would be great! (By the way, I'm running Dexter's latest rom on top of eLocity's official firmware update).
I'm posting 4 hours 54 minute uptime right now with a quick 10 minute game of fruit slice, light to moderate web browsing, and moderate to heavy instant messaging. I have 29% battery left.
I generally set my apps to sync no more frequently than 30 minutes at the least. I turn the screen off when I walk away to do something. Other than that the tablet stays running on my couch side all day.
I have also seen it go for days on standby mode without going dead. I'm happy with the battery life. My Archos isn't much better, and is much less powerful of a device.
I'm also on ElociMod (which is based off the newest firmware... )
cant get more than 4 hours no matter what i do. running dexter's modc
We might be able to help the battery life using some clever tricks with SetCPU. I know it helped on my Pandigital Novel, and 2/3 on that device was used to power the screen, as opposed to ~1/3 for the processor. I'm gonna guess it might be the complete opposite of that on the A7.

It doesn't... it will FC.
CPU Tuner installs and runs. It shows a min of 260 MHz and a max of 1000 MHz, and it has profiles based on battery charge. I just installed it, so I don't know what to expect.
I wanted to resurrect this thread and post my experience with A7 battery life.
I am running Dexter 1.2, brightness at 35%, WiFi always on, Bluetooth mostly off, screen timeout at 2 minutes. Syncing three mail accounts, weather and Google calendar. Limited or no background syncing of other apps.
My typical day with the device consists of;
a full charge in the morning
3 to 4 hours of standby time
30-45 minutes of web use
another 3 to 4 hours of standby
3 to 4 hours of heavy web, texting, reading, and games
I place the A7 back on the charger at night and it usually has about 20%-25% charge left.
I figure I am getting about 4-5 hours of use and close to 8 hours of standby each day fairly easily.
This battery life is very comparable to my Droid 2 Global.
The ipad battery has more than 4 times the capacity of the A7, but only twice the run time.
I know a lot of people brag about great battery life, getting 20 hours or so of life, but really, unless you have a godly battery, I doubt with heavy usage you could get more than 6 hours of life.
I'm asking for opinions here, because I get about 2 and a half hours of Display usage before my battery dies.
Is this about normal? I'm sure the signal plays a part, as I average around 92 - 100 dBm signal in my city, which I know isn't very good.
I turn off my 3G whenever not in use, I have display set 30% brightness, auto-sync is off, gps, bluetooth, and sometimes I put the phone in airplane mode when signal is weak.
My point is, even with all the battery saving tricks, I get about no more than 2 hours and 30 minutes of Display usage, regardless of whether I'm playing a game or using the browser.
Running CM7, with Conservative, min 245, max 998 MHz as well, stock kernel.
What do you guys get?
Hit up the sprint CS chat. Complain about battery life. Ask them if they can comp you an extended battery. Took two tries but a csr refunded my battery purchase in full. In my case I bought first then asked for refund. Worst case you could just return it
i get about 3 hours screen on with stock and double with my chinese extended battery.
they're both more than enough for a full day. i dont see how i would be bored enough to be using my phone screen on for 3 hours in a whole day anyway haha.
i think some people consider playing music for a long time a "heavy" use of the battery which in my opinion isn't true. playing music barely drains anything when it's on for a few hours even with 3g.
but yeah i dont think the stock has enough juice for screen on more than 3 or 4 hours. i get 20 hours usage frequently but that doesnt mean the screen is on the whole time. in a day i probably play half an hour of games read news on the bus for 40 min to and back. read some news browse the web during lunch and listen to music throughout the day.
My opinion. About 100 texts, 15-20mins of angry birds 4G on, lots of web browsing. That's heavy usage.
With stock battery I get about 5-6hrs of heavy usage. On Myn RLS5 with #15 kernel. Moderate use (4G off but wifi on, no angry birds) I can get about 8-9 hrs with stock.
mmm... i dont use 4g so can take that out. I send about 300 texts, web browsing games all that stuff. get about 4.5 hours of screen on.
Heavy use to me is prob checking Facebook and twitter at least 3 times an hour. Receiving 2-5 email an hour from 2 different accounts GMail and Exchange. Playing Angry Birds, The Sims 3 and Bistro cook around an hour combined for all of these.
Reception at my job is not that great so I get around 4-6 hours if I am using it a lot. If I turn off the 3G when im not using it then I can get much more life out of my battery.

bad reception = crap battery
My 'heavy use'
usually everyday I have work which is 4-6 days a week.
Over 350 texts a day (incoming and outgoing)
3 hours total gps/navigation
about 20-30 mins of total talk time
oc'd to 1.228ghz
about 2.5 hours of 4g ON
gps on entire time
live wallpaper always on (nexus revamped pro, fps is at 32, speed at 150)
used multiple apps (psn, xda, mx moto game, setcpu, 7 widgets total)
use flashlight app on high settings for maybe 1 min total time
screen brightness is always at 100%
I get anywhere from 7-9 hrs total time unplugged, I usually have about 10% left when taking these numbers.
I bet I could get a pretty good number if I underclock and turn auto brightness on.
My heavy use:
Get to work at ten
browse almost nonstop
text in between
youtube a few times
...on the charger by 2
Like someone else said, low reception kills batts.
3+ hours a day of Words With Friends.
Guilty as charged!
I get 4.5 hours every day of listening to Mike and Mike in the morning on the new ESPN radio app. I also check facebook several times...and get a few texts. But im sure the 4.5 straightforward hours of streaming is what does the damage.
I stream Radioio.com on my phone for about 5-6 hours a day while I'm at work.....I have the extended battery...and when I get home, I have to toss it on the charger Good thing I have unlimited data....

What rom are you running. Op is on cm I heard it was hard in the battery as is. I finally upgraded to a extended battery. The extra size isn't bad and you wont regret doing it.

I assume the bad reception must be the worse offender to my battery. I wasn't complaining or anything anyway, I was simply curious.
I have the stock battery, and 2 extra batteries for heavy usage. I primarily use my phone at work, as sometimes business is very slow and I rely on my phone entirely too much for entertainment.
I've been told my usage is moderate to heavy:
MikFroYo 4.5
MS79723's SBC #15 v7
Slayer's Cyan Dragon Theme
4g always on
gps only on when using Foursquare or Maps, otherwise off.
200-300 texts
5-10 minutes of phone calls
1/2 to an hour of angry birds
half a dozen feedr news widget articles I'll use the browser to read
30 minutes of general web browsing
Check e-mail several times
check calender once a day
Stream some music on Subsonic (only when I'm in the car but I have a car charger so I don't count this).
Check fantasy hockey leagues three times a night when there's games on
Check facebook/update status many times
Sometimes I'll use wireless tether and there's a chuck norris app I'm fond of, but that's not everyday. The kernel undervolts, I don't keep my screen on unless i'm doing something and with the SBC I get normally around 12-17 hours a day if I don't tether or dilly dally too much. Since I have a car charger and I charge at home when I'm in the shower or sitting at my desk, my phone rarely drops below 50% on my average day.
If I were in an office, I'd connect the phone to charge to my computer and the car charger has been invaluable. I highly recommend charging it whenever it's just sitting there (even if it's streaming something).
That's how I get through my day
I again wanted to say thank you to all involved in making the Fascinate the best phone it can be.
I have instantly noticed a considerable battery life improvement using this radio.
Just thanks.
And juice defender doesn't hurt either..
You must not be using your phone at all, mine only gives my around 7 hours.
Really? Only 30 hours? My white fascinate could go for 3 days with light usage and 2 with moderate. I bet you it could last for 4 days if I didn't do anything but text or call people. Oh and don't use battery apps, they don't do crap honestly. The only thing that kills your phone is games and the screen being on. But if you use your stock Froyo task manager then you're good.
I am confused a little but mostly dissapointed in how people report usage and battery life around here. I think for the most part it is simply a result of how subjective the term "use" is defined in all it's various "states". For instance what I consider "heavy usage" might be beyond what a lot of people would consider to even be reasonably expected. On the other hand you can have another person who thinks using their phone once for a few minutes every hour is heavy usage. Some seem to be reporting standby time like it is normal usage, which depending on your definition could be true. Some people seem to be obviously "lengthening" their "epeen" for some unknown sad reason which is the part that is dissapointing.
I can say, once, I left mine on after using it all day Friday, set it on a table at home and I can't remember why but I didn't touch it again till Sunday afternoon. It literally only used a few percent battery life. This is abnormal usage to me. This might be "normal" for some people.
Some people like myself are device addicts. I don't go anywhere without my phone. I rarely make calls on it. I rarely use my powerful desktop for any casual pc use like web surfing, IRC, listening to music, personal gmail and work email via exchange. I do all of that on my phone. My day consists of picking up the phone fully charged at 7:30am, at work by 7:45, and then once in my cube the headphones get plugged in and between voodoo sound and power amp I get pretty lost in the tunes. All the while I am getting constant email delivery notices. I probably look something up on my phone a few times a day. It is on wifi all day at work and home.
Once home I stay on it after dinner....once the kids are away, the wife and I sit in the living room and she on her laptop and me on my phone we kinda watch shows together while surfing or whatever. So hours of constant use in the evening. My screen is on a lot because I don't go long without doing something on it.
I have recently been getting around 14-18 hours if I run it to dead on the 2.9.2 + latest Voodoo sound enabled kernel floating around but was on eb01 radio. I flashed ec01 radio tonight hopefully to see better battery life but there's no way in hell I would be expecting anything close to 30 hours or days!? Not unless I laid my phone down and walked away for a few days, then sure. I consider myself to be a fairly heavy user.

In my case Syn Ack is right about the screen. This past weekend I gave my phone a real test. I put EC01 on, got rid of most of the bloat and left the phone in that state. Didn't install any extra apps that would run in the background. Only had 1 home screen with nothing on it but a black wallpaper. The phone looks boring as ****. lol
From what I saw, the only things eating battery was having the screen on, a small bit of time with no signal, followed by android system and any other apps I may have used which didn't make up much compared to the screen.
I love the screen, but it's like a high maintenance girlfriend. Its sucking the life outta this phone.

That's pretty much par for the course. The screen is always the biggest battery drain in any phone out there, out of any piece of hardware in any phone. Trying to keep the screen's brightness as low as possible, and it off whenever you don't need it on, are probably the best things you can do to improve your battery life (followed by deleting crappy widgets like the Facebook one that keep your network up constantly).
Then again, I set my screen to have a 2 minute timeout, because the 15 or so second default way too often caused the screen to turn off on me while I was reading something and I generally use the power button to turn it off when I'm done. I figure, as long as I can make it till night, that's good enough for this phone 95% of the time (the other 5%, I can generally plan ahead).
I honestly don't see poor battery life as in issue for this phone.
Mine will last for 3 days of extremely light usage, 2 days with light-ish usage, and if I hammer on it and play some games, 14 hours or so, it'll beep at me.
IMO, this is not an issue. I have seen the battery life increase with the latest updates (OC Kernel from imnutz, SFC2.9.2, EC01 radio) - and I was happy before.
I also don;t think that you can really count on what other people see as anything but a hopeful ballpark figure. We all know that each of the phones HW is a little different. We all know that our setups vary greatly. We all know that we use the phone differently.
So, hoping that something will be a be all, end all guide as to how long your phone will stay powered depends on so many variables that you have to tweak it for your use.
FWIW, I run live wallpaper, 7 screens and use OC steps up to 1400 and I am very pleased, dare I say impressed with the life I get out of the phone. I also keep a spare battery fully charged - I guess this helps me care less and just ooh and ahh when it lasts more than a day.
Mine gets 150 hours...... Turned off.

With the phone sleeping (screen off), my battery drops at MOST 2% per hour. I don't use but a couple of widgets, Facebook and weather. My sync time for Facebook is 1 hour and weather is 2 hours.
For me, when I was referring to my 2-3 days of battery life:
Light usage (3 days): a few phone calls a day, < 25 texts, no internet, no market, no games, no battery control apps except using Task Manager wisely.
Moderate usage (2 days): regular phone calls, < 50 texts, some internet, maybe a game or 2 but not for long, Task manager.
Heavy usage (1.5 days): regular phone calls, texting all the time, heavy internet, games, rom flashing, playing music a bunch.
Super ridiculously heavy (1 day): phone/text/internet/games/music, all nonstop heavy usage.
Super light (3+): Data (3G) off, a couple calls, light texting, using Task manager wisely. It can happen...
One thing I have come to find out is that not only your screen is the number 1 factor but if you live in an area that phases your phone in and out of 3G very often, your phone could easily drain 10% per hour. The IT building here on my campus has god awful reception and it drains at 10% per hour but when I go home I only see 1-2% not doing anything at all. Wifi is a battery drainer too.
There were a few nights where I remember hitting task manager and clearing out every single task and everything possible running, turning off data, and turning the screen off and the phone did not even lose 1% of battery over 9 hours. Perfect reception.
So if you see terrible battery, try using your screen a little less, or turn down the brightness. Try a *228 for your radio towers update. Cell standby can you get hard if you're in bad reception.
The best thing you could do to save your battery is kill all of your tasks, turn off data, turn your screen off, and change your sync intervals to 1hour+.
i'm on ec01 for about 12 hours now, sFc, in nemesis OTB kernal underclocked using volt settings gives me about a 8 hours with the amount of usage I put it through. Serious wifi, network usage, processor spiking and multi-tasking. Overall what one would expect from android.

Heavy user, this seems about right. Your battery goes from 100% to what % before you recharge?
