Yes... none of the 2.1 ROMs currently provide long battery life times. I believe that one of the chefs said it was because of the kernel and that it won't be fixed until HTC releases or leaks an official Hero kernel for Android 2.1.

However it also depends on what you think would be a good/adequate battery life.
Personally I charge every night so as long as the phone lasts circa 24 hours it is fine with me.
All 1.5 based roms should give you battery life over 24 hours even with everything turned on.
as for tips:
-turn of wifi when not using it
-turn of mobile internet when not using it
-turn of gps
-always put phone in sleep mode (end button) when not using it
- screen time out turned low
- backlight on low
- kill tasks that run in background
- don't have a bright wallpaper
Just depends how extreme you want to go
I have a decent battery life on the rom I am on (see sig) and I use a brightish wallpaper and auto backlight but always turn wifi off when out of the house.
Flashing a new radio file can also help battery life.
Edit: with a bit of use I have lost 5% in the last 8 hours on my phone today

Mhm too bad i like to use 2.1
Does 2.1 Roms drain the battery so much more?
Battery life is very important for me...
I am running the original Rom and i had to charge my hero every night, too.
But one day is okay...
Thank you for your tipps (bright wallpapers *lol*, but it make sense^^)
So what are you fav. 1.5 roms?

P.s. Does HTC want to upgrade the hero to 2.1 ??? Would be awesome...any dates?

indication is yes they are updating to 2.1 however they have not released any official confirmation of when.
rumors are March and/or April, but don't hold your breath

SenseHero 1.6 is awesome 1.5 ROM
Also it uses a nice theme, and can last for more than a day

Latest rumour says end of April

To me BeHero has the best battery life of the 2.1 roms and Villain had the worst (the life would literally go from 100% to 50% in 4hrs and I barely touched the phone).

See I am on Villain and have been on every version of it and never had battery life that bad, and VillainRom 3.4 is very good battery life.

I put on 3.4 yesterday and ya my battery life was terrible. The only thing is that I hadn't ever updated my radio. Now instead of it being dead within 4-5 hours I've gone over a dozen and my battery is down to 45%, which is pretty good for me. I'm a pretty data intensive with my phone.

if you want to test the battery life, test it 2 days or more!, because the first day every rom(almost..) is draining fast, because then it needs to set up everything etc(idk excactly why)

i agree...using 3.4...i feel the battery is not all that bad..(yes not as good as 1.5) but just about manageble..
if anyone has any more tips please let us know

Wow I find it very hard to believe that you only lost 5% battery in the last 8 hours with little use...do you have mobile data on or off?
Even with no use at all I can never get 5% decrease in 8 hours, regardless of whether its a 1.5 or 2.1 ROM. I keep my mobile data on all day and night and with no use at all i lose like 20% battery life in 4 hours.

If you want 2.1 firmware with good battery life, go foe BeHero_v1.3.2, I am using it without any trouble!

Trust me I was not lying I have no reason too.
Will report on what it does today.
Yesterday I had mobile internet mainly off but turned it off at certain times of the day.

So far today (3 hours since fully charged)
-wifi for about an hour
-use wifi things during that time (seesmic and News Rob mainly)
- bluetooth for 45 mins (journey to work)
- mobile internet for about 40 mins
- downloaded an app and tested it (used barcode scanner to scan a barcode (twice) and go to the download link)
- synced emails
- sent a text
- mobile internet now off and back asleep
And a reboot as my connection was lost for some strange reason
lost 2%

i can only say that perhaps ur battery is a special one..
i cant even get half of that with 1.5 rom (with the same usage)..i will surely lost like 10% with that kinda usage on phone..
no offense..but..unbelievable...
my current setting :
GPS , WIFI & Bluetooth off..
brightness around 15%
dark wallpaper..
mobile internet on when browsing needed

@aziz831
Lennyuk´s battery consumption is real. My battery would last 216 hours just in idle. But that would mean just asleep and waiting for a call.
I use WiFi 18/7, I have in that time mobile data enabled, I have a brown wallpaper and my backlight is on lowest level (but I can still see everything). My average loss is 1-1,5 % a hour if I´m in idle with all this enabled. Over night I do disable WiFi and auto sync, that saves a lot of power.
My average time of usage with one load is about 80-96 hours.

[Q] This question shall determine my ownership of the Xperia X10...

Does the next update (2.1) somehow include a way to improve battery? I'm guessing no, wouldn't you need to replace the battery itself?
There may be battery performance improvements in the next update. My battery life is actually stellar. I set Timescape to update every 3 hrs and have brightness at about 75%. Off the charger at about 7am and at midnight that night I'm usually at around 40%. That's plenty good enough for me.

I dunno about the update and battery life but, Its 100% to 20% in 25-27 hours for me which i think is awesome as my usage is high.
Try setting the updates of your apps lower, check the Batt usage history from the settings menu to see what sucks the juice more.
If you want more battery life then you'll have to sacrifice some updates, which according to me ruins the entire purpose of having such a high-end smart Android device. Just use the phone the way you like it, have the charger with you always
Whatever phone you choose i think you are going to have this issue since batt usage depends solely upon the way you use your phone. In 2.1 live wallpapers suck more juice so you'll be advised to turn it off its either functionality or performance, the decision is yours
According to me any phone u buy will have same battery life or there is 70% Probability to have worst battery life. X10 has one the best battery life amongst all smartphones

Hmm... could it be just me? My battery went from 100% to 53% from just staying locked over night (around 9 hours). I checked what's been eating it and it said "Cell Standby" and "Display". My brightness is on the lowest possible and Wi-Fi and Bluetooth is constantly off. I'll check that Timescape stuff and try to get the App Killer from the Market... (if my device even had a market!).
nah this device is ****ed up ...
sony homepage says that standby time is around 450 hours .... (more then 17 days!)
i dont have timescape on autoupdate - the only thing i do is gmail push and i get 1 and maybe 1/2 day(s) of standy time (depends if i make 1 call or not )
the update should increase it a lot i think
btw if some1 has a 2nd phone please try this:
charge it fully and then turn it off completely ... after 17 days turn it on ... my bet is it wont turn on coz the akku is totally empty...
I have no Wi-Fi at my hotel and I don't have a data plan. How on earth does it drain this much battery. I'm gonna go turn off every app and try another night just on standby.

Good question for you actually, how long have you had the phone? my first 4-5 charges were appauling but it quickly got better and now i could not be happier. more often than not getting 7am - 11pm the next day (whats that, 40 hours or so?) out of one charge, with plenty of go left.
Mine is running RB##26 firmware, rooted and a chunk of apps deleted though.
When i first got mine it was a bit poo, remember for the first 5 or so charges to let the battery go down pretty low and it will improve battery life.
Get runcpu and you're golden.

Sounds like you're running 014 firmware - I had the exact same problem until I updated to 020. The whole battery usage profile changed and one hour of standby only uses up 1-2%.
yeah, the 020 u/g makes a difference. I've rooted and overclocked mine, heavy usage on 3g can drain the battery in c12 hours but more than adequate for general usage
I'm a big user. Even with my G1, I was happy with a day's use. Anyone who thinks they're gonna get days of use without a charge is kidding themselves. A smart phone with a big screen us gonna suck juice regardless of what you do. As many an XDA user will tell you, keep your charger or at least the cable with you wherever you are. With FW026 it did help a little, but if you need life from your battery you really do need to sacrifice some of your widgets or updates.
MrZ
Today my battery have gone to 10% in about 10/11 hours, i'm using sip and wireless are active all day, even when it are on standby, installed some apps and played some games, some calls, its good enough, sometimes i get 2 days, depends on what you do, you can do some tricks...

Battery drainage solution, I think

So, I have had a serious battery drainage problem, like most of hd2 users with wp7.
My battery usualy run max. 24h!
Now my phone run 2-3 days without charging.
I have just turned off connection with xbox live
So, go to the settings -> applications -> games, and turn off "Connect to Xbox Live"
I have 3G off
Data connection on (but mailbox, shares, weather ect. is updated manualy)
I hope this will help you...
Interesting will give it a go..... I have to say I beleive this and other 'solutions' may be solving part of the sympton and not the root cause BUT if it helps that's always good news until the chefs can get to the bottom of it!!
Thanks will let you know.
Cool cool
I already did this now.
Will also check it, and provide feedback.
Battery life is a bit of a problem, but atleast i have a car charger
I will give it a try.
3G on
Data connection on
its work this solution ?
I think it should work. I checked battery dainage with Xbox on right after turning phone on after sleep - about - 42 mA. So without use of the phone max time is less than 30 hours. But if Xbox is OFF current is just 5-7 mA. Means 6 times less on stanby!!! Will give it real timing try. Used Battery tool to measure current.
hello
did not work for me
It doesn't work in real life. After start some apps and close it current returned to 42 ma forever.No more 5-7 ma. Only turning on Airplane mode gives 2-3ma standby. So all bad battery life comes somehow from radio is too active.
Hello all.
I hear that if u change the radio version to a down one you have more battary life ..is it true ? there is anyone that tried that?

From my experience (only 3 days rooted LOL) you have to find radio that works best with your carrier. Better reception will stop phone trying to find masts, hence improving battery.

I don't see any problem with battery draining. If it gets you over the day, what do you need more. Over night you plug it in.
I have all switched on (location too) and no problem with music maybe 1h, reading mails, checking facebook several times surfing internet and news. I would even say its better than WM 6.5 doing the same, at least the same.
I think battery draining is not hd2 problem wp7 is the problem
the real solution for batery is - turn on 3G
try
batery life is 2 days with many calls, play and others.
22.03 - 10:00 am - charget
24.03 - 12:00 pm - charget agaen 50 hours
this is experience of one my friend and works,
I didnt try becouse I wait new rom

It is definitely problem, comparing with all android ports where battery life is x2 more longer than in this "simplified" WP7!! Battery is dead in a half day in a standby is normal for you?
I solved my battery calibration issue by installing HTC battery tool, it fixes the calibration of battery so correct full charge is 100% and correct no charge is 0%. Give this a try, I am sorry I cannot post the link but I found this app on XDA too.

ok im running HD2O_1.04_DFT_LEO70_RELEASE and WAS running radio 2.15 and after 3 days testing and very poor batter life with registry fix, i decided to change my radio to 2.12. and so far after 7 hrs of testing ( full data, 3G, and internet browsing + youtube here andhier) my battery is still 3/4 change the radio it take 2 sec. to do.
with the old radio i was using, i went to work at 6a.m. got off at 3p.m. and i only had 1/4 left. with radio 2.12 i still have 3/4 and i used it more because im no longer at work.
try it good luck it worked for me
i will post another update around 6p.m. pst.

[Q] whats the best battery effective kernel?

this is the only reason i hate CM7. it drains battery like hell. yes, im already using "conservative" cpu governor and have JuiceDefender installed.
when i was on the stock LG rom, battery life used to be about 3-3.5 days on normal usage. after flashing with CM7 (the latest stable version), i need to charge it every night. if i do a lot of net surfing, battery will last for only 15 hrs.
is there some other gingerbread rom with which i can get back the normal battery life?
ive never tried this rom but ive read that rjtchn's cm7 has good battery life. the last time i checked his rom isnt on xda but u can google his rom

First, you can go back to Froyo by flashing the stock ROM through KDZ. But all your data would be wiped out. Take backups.
And regarding battery backup, I think 25 hours of battery backup on moderate-heavy usage is fine. I'm not sure whether we can get 3 days on froyo with the same usage. I didnt use froyo much as I immediately rooted my phone and flashed CM7 based ROMs.
On Andy's ROM with Andy's kernel, I can get 25 to 30 hours with heavy usage, with 6 hours of sleeping period in between. So it is 20-24 hrs of almost constant heavy usage.
void. #forever
I'm using void. #forever with Franco's v18 BFS kernel.
I had 2 days & 20 hours with moderate calls, SMS & browsing. I think I could have reached 3 days until an exercise app surprisingly kept my phone awake & drained the remaining battery.
Using GB 2.3.3 - at the moment for testing purposes GingerCriccoROM 1.2 and latest Franco GB kernel. 3G data always on, sync on, (fb, twitter, gmail, email etc. autom. check every 30min.) Calls, sms, browsing, pretty heavy use and i got after first full charge and battery stats wipe 1d 14h - still 6% left. OC 480/729 smoothass. Still testing - at the moment i have 30% battery left after 1d and 7h.
i run void #forever and franco kernel
it usually last about 2 days on average (48+hr), i dont use the phone functions that much, mostly just browsing the news and sometimes GPS when i get lost out there, but i keep wifi/background/sync always on since i rely on gmail/gtalk/gvoice heavily
horrible battery life
flashed rjtchn's cm7 just now. And havent even restored backups yet. And as I surf on xda now on my wifi, battery is decreasing by 1% every 2 mins in front of my eyes.... it was 100% at 5.35pm and its 89 at 6.04pm now..... WTH is happening? Also to mention, I had bought my phone only a month ago with incredible battery till I started flashing Roms...
I'm using. Rover theme. Does that have. Anything to do with battery?
I had wiped battery Stat when my phone was in 100%, then I flashed the rom, rebooted, and then connected to USB mass storage for 20 mins to do transfers. ( it got charged again). Anything wrong in this process?

I am wrestling with battery life. Not being able to run 24hrs on one charge seems silly to me.
To use some round numbers, from best to worst given my standard usage patterns: {0}
48 hrs (2% per hr drain) -- stock LG 2.2 ROM rooted, crapware removed, SetCPU onDemand 122-600. Consistently runs 48hrs on a full charge.
24 hrs (4% per hr drain) -- stock ROM as it came out of the box.
18 hrs (5-6% per hr) -- CM7 RC1 unchanged. It seems closer to 5% per hour when I set onDemand in CM perf settings to 122-600 and tore out the launcher (using the delightful Zeam instead)
I can go to sleep with my OptT on the bedstand and wake up 8 hrs later and it's dropped from 100% to 60%.
I did do a brief test of Void forever and like the cleanliness of it. But development appears to be ended so no hope of BT working well or battery optimization. If I had an extra T500/509 I'd send it to the dev so he could continue testing. I did run it for a few hours but after I tested BT I didn't have the heart to go install all my crap on it for extensive testing. {EDIT: going to try it out today and see if I can hit 48hrs with it}
I am a big CM fanboi so I would love to hang in there with Mik until BT and battery are better. I mentioned battery drain in a (pre-CM7RC1) thread once and it was not well received, so I haven't mentioned it again until this thread.
If BT and battery don't eventually get improved (and I assume they will) I'll stick with the stock, rooted ROM.

I'm on gingerlol with paolos kernel. I use my phone for a few messages a day and about 1 call per day. Playing around with the phone depends, somedays more somedays less. Battery lasts 2 to 3 days. Can't remember having more juice on stock froyo.

Well... reading you guys talking about 2-3 days of battery life makes me think that I'm either doing something wrong, or my battery is a bit damaged, 'cause the only way I could think my Optimus One would last for 2-3 days would be with no use at all.
I got this phone from a friend who had owned for only 2 months and the phone was already rooted and with a custom ROM already installed (Light 2.2.2 which is fairly close to stock). With that ROM the battery would last for a day max.
Shortly after I started installing other custom ROMs and testing them:
- Devoid Froyo Final: The most responsive ROM I've tried, but I had horrible battery life with it, with only around 18 hours of bat with moderate use and 3G on.
- OpenOptimus: Seems a bit laggy to me, and battery life was not even better than Devoid's
- LOL 1.4.2: I finally settled with this one. The ROM is pretty responsive (although not as snappy as Devoid) and at least with this one I can have a full day of battery life (sometimes a bit more).
I must say that I always keep an eye on apps running in the background and stop those I know I don't need always running. I also use Titanium Backup to "Freeze" apps that I know I won't use on a daily basis (like Google Maps and Navitel GPS).
The other thing I'd like to mention is that I keep GPS off (unless I specifically need it), but I always have data ON, either via Wifi when I'm at home, or 3G when I'm out of home. My Wifi Sleep Setting is set to "Never".
The only two apps that I know are working regularly on my phone are:
K9 Mail: Receiving mails for 5 Gmail accounts (all configured as PUSH so that shouldn't drain much battery)
Whatsapp: Receiving messages from friends and family, but that app is also PUSH so battery drain should be minimal also.
Overnight drain with Wifi On is about 5%
What do you guys think?
BTW... probably during this week I'll flash one of the 2.3.3 based ROMS (GingerLOL). I hope that being a "LOL" Rom it would be as stable as my current one.
Not a long test, but I did put all my apps back onto void #forever for an apples to apples test.
Set it on my nightstand and we both slept for 6 hrs. 100% down to 66% in 6hrs, for a drain rate of 5.7% per hour. Gack.
I suspect the real killer is the broken CM7 bluetooth stack in our devices at the moment, but since I use my phone gets used as a wireless mp3 player most of the time I really need it. When CM7 for OptT gets a fix for BT I think It will be nearly perfect for my needs.

I am wrestling with battery life. Not being able to run 24hrs on one charge seems silly to me.
To use some round numbers, from best to worst given my standard usage patterns: {0}
48 hrs (2% per hr drain) -- stock LG 2.2 ROM rooted, crapware removed, SetCPU onDemand 122-600. Consistently runs 48hrs on a full charge.
24 hrs (4% per hr drain) -- stock ROM as it came out of the box.
18 hrs (5-6% per hr) -- CM7 RC1 unchanged. It seems closer to 5% per hour when I set onDemand in CM perf settings to 122-600 and tore out the launcher (using the delightful Zeam instead)
I can go to sleep with my OptT on the bedstand and wake up 8 hrs later and it's dropped from 100% to 60%.
I did do a brief test of Void forever and like the cleanliness of it. But development appears to be ended so no hope of BT working well or battery optimization. If I had an extra T500/509 I'd send it to the dev so he could continue testing. I did run it for a few hours but after I tested BT I didn't have the heart to go install all my crap on it for extensive testing. {EDIT: going to try it out today and see if I can hit 48hrs with it}
I am a big CM fanboi so I would love to hang in there with Mik until BT and battery are better. I mentioned battery drain in a (pre-CM7RC1) thread once and it was not well received, so I haven't mentioned it again until this thread.
If BT and battery don't eventually get improved (and I assume they will) I'll stick with the stock, rooted ROM.

my battery life isnt that good either. but then again more performance=less battery life
Void #forever is truly the best rom I have ever tried.... The best thing on it is that its "void" and u can choose which stock aps to install. Thnx a lot guys for recommending me this rom.
Rjtchn's rom had better performance. Quadrant score was 1005 without overclocking(i don't remember the exact). Void's score is 840. But it has incredible battery.
Its the first rom I have ever seen with cell standby having the max bat. usage on 2g network. (all others had android system). That means just by putting on flight mode, things would go even better

It's a balance issue, I guess.
I was researching another issue and so set my phone (as described below) down for 20hrs 23mins and it is now at 84% battery. 23.3hrs / 16% battery usage = ~0.75% per hour.
Compare that with 5-6% an hour I was getting with CM7 on the bedstand. I suggest that CM7RC1 is , despite it's general wonderfulness, not providing 6x the performance for 6x the battery drain.
I am a CM faboi and have done the "buy Cyanogen a beer" thing on his site. I eagerly await CM7 going gold for our devices, and I hope the battery/performance balance is on parity.

ATT version of SG2 sucks your battery?! *Fixed*

Update and FIX!
My phone is no longer draining massive amount of batt life when idle (3-5% after 7 hours of idle), android system usage is now down to 5-15% instead of 78-97% from before.
My fixes.
1. Turn off data syncing
2. Turn off wifi while on the road (so wifi doesn't constantly look for signals).
3. Clear memory
Yes, att installs a lot of bloatware that constantly update for changes.
If killing those services AND disabling data syncing doesn't help your problem, then you have a kernel problem (like myself).
If this is the case, do the following:
1. Take phone back to att and get a replacement
OR
2. Re-flash your android with the STOCK kernel found here
http://forum.xda-developers.com/showthread.php?t=1286432
OR
3. Reflash with cognition x2 (reported to solve a member's problem, I didn't try this myself).
NOTE** This will root your phone, you will NOT get the exclamation mark during boot up, but kernel counter may be at "1" after this process.
Re-flashing my phone AND applying the three tricks I mentioned above worked for me..finally my phone is no longer crippled with crappy battery life and recharging is A LOT faster now.
I must be going crazy but this sg2 is killing me. I got it from Att yesterday and the battery life has been pretty HORRIBLE. (First time android user btw).
The phone will eat up 10% of my batter life after only 90 mins of idle. I checked the battery usage and Android OS is at around 78%!!! How do I fix this problem? I downloaded OS monitor and didn't really see anything that uses a lot of CPU, except for certain files syncing from time to time (but 2-3% usage usually).
Checked with battery spy and apparently the majority of the time, the phone was hovering around 200mhz 70% of the time and not deep sleep.
It's sad to have only 1.5 hours of display time with a battery of 45% left (7 hours total time)...coming from an Iphone 3gs, this is just unacceptable. I almost flashed to the 2.3.5 firmware but noticed it's NOT compatible with ATT's version of SG2.
I see people who have a total time of 2 days AND a screen time with 3 hours with 30% battery left. I wish I can get half that!
Running on 2.3.4, can't be the infamous drainage bug right? Thought that only happens with the 2.3.3s
Wifi on, application sync on, GPS off, brightness at 25%, using live wallpaper (the windmill). No active apps on. Downloaded aim, epocrates, battery monitor, cpu spy, and os monitor..rest of the apps are stock.
Update
According to my CPU spy
For the past hour that the phone was in idle
2:20mins at 1200mhz
4:52mins at 1000mhz
8:33 at 800mhz
1:28 at 500mhz
10:11 at 200mhz
33:36 in deep sleep
Currently Android CPU usage is @ 97%, display time of 7mins(2%)
2h 30mins since last charge (97% charge)..current power is 79%. Did nothing but idling and checking battery life.
So...that's 30 mins out of the hour in which my idling cellphone was hacking the pentagon....
Also the cellphone is a tiny bit warm to the touch (not cold)
I have 35% battery life remaining and have been unplugged for nearly 11 hours. This is significantly better than what I was getting with a Thunderbolt on Verizon, where I was needing to charge after about six hours of use. 11 hours and 35% remaining isn't the best in the world, but it's only been two days. The phone needs a few days to charge and discharge to determine true battery stats and will probably get better.
Being that this is your first Android battery life will not seem great but let it settle in for a few days it should get better.

If you only got the phone yesterday, its way to early to make any judgments on battery life. Battery needs at least 3-5 days to settle in and build consistent battery stats.
Also, what are you settings? Auto Brightness, Bluetooth, GPS, auto syn(exchange emal, gmail, facebook, etc). If your not using these, they should be OFF. It's easy to manually refresh email, etc.
I've seen some people reporting very high Android OS(over 50%) but still getting solid battery life.
I'm at 1hr display time, heavy texting. 72% left, been unplugged for 12hrs
no people what this guy is talking about is the android os bug. i have it too. hopefully an upgrade or different rom will fix it. my phone has been unplugged 11 hours with only 1 1/2 hour display but android os has ran for 52 minutes and now im at 32% battery life. once this bug gets worked out the battery life will be amazing.
I don't think that there is an android OS bug. My android OS shows as being 42% with 13hrs of moderate use and I am still at 67% battery remaining. This is by far the best battery use I have ever experienced on an android device! My cappy would not even come close to this performance and this is on stock ROM and kernel.

I'm very happy with mine, this was the first total drain on a new battery so I know it will only get better.
Total time: 18hr 25min
Display time: 4hr 48min
I think it's the system os, not the hardware. There were a few times when the battery didn't discharge itself at 7%/hour (had it idle for 3 hours and it went down like 2%).
And yes, everything is turned off except the sync app data and wifi. There's no option to turn off 4g btw. It's just weird how sometimes it's in this mode of power drainage, and then sometimes it doesn't drain much..but most of the time, it's draining.
I seriously doubt the phone can only run 2.5 hours worth of heavy usage or 12 hours of standby (it should last days!). If this is "normal" for android, then maybe I should have a visit back to att and exchange for an iphone (and I really don't to!)

I agree - as I said in the Android OS drain thread, even in "good" situations, Android OS displays way high on our systems. I think it's a reporting bug.
I dropped 2% in 5.5 hours completely idle (sitting on my shelf) last night - Android OS was at over 60%. It seems that so far for me, the higher it is, the better my battery life is.
I drop around 15-20% in 9 hours of being mostly idle at my desk at work - it's a weak-signal location so the radio eats much more battery.
One thing is that unlike first-generation GalaxyS devices and interim ones like the Infuse, the GS2 has a coulomb-counter type of battery gauge. This type of gauge sometimes needs to be calibrated with multiple charge/discharge cycles or it will misreport battery state of charge. (However, when calibrated, it's much more accurate.)
Edit: I do have some power management tweaks in the kernel I'm running, but they don't make that much off a difference except in some high-drain corner cases in my experience. I'll be releasing it sometime later this week depending on how well these antibiotics do their job.
Do i need to install a battery app to see the percentage? or we have a way?
Install this app:

If you see "DataTracker-FD" or "Fast Dormancy" as the top wake lock, go into dialer
dial *#*#9900#*#*
disable Fast Dormancy (FD).
By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.

That applies to the I9100.
As far as I can tell, the I777 has FD disabled by default. (This may change once I9100 ROM ports start showing up)
Okay, charged my battery to 97%(I got a beep saying it's fully charged). Idled for the past 2 hours and 22 mins. Battery is at 86%.
According to the battery, my screen account for 2%, and the android system accounts for 97%.
This is a stock phone guys, I have no apps installed!

Just search up "battery indicator" in the Market and you'll get a few to choose from.
I too got mine yesterday and started tinkering around with installing apps and such to test out all functions before I rooted it and move onto cm7 most likely. The 1 things I noticed was that the battery was NOT completely full when it was first turned on at the store so once it got a little lower after playing with it I charged it up overnight. Today the battery was WAY BETTER and was not dead yet. I have been using it NON STOP today, rebooting it, testing it, trying to root it, rebooting some more, some time using tango to test it out, watched a Netflix movie, pretty much taking full advantage of it all day. I finally decided to charge it up and use my Captivate a bit. I didn't keep track of usage and times today but I KNOW it lasted a WAY LONGER time with all I was doing with it than my Cappy. Tomorrow I will check more out possibly before putting on a rom.
So LOOOONNNNGGGG STORY short make sure you charge it up once you get it before messing with it too much and then it will LAST LONGER.
Sent from My KickAss Captivated CM7 OC'd 1.5Ghz/Undervolted
After two nights of completely draining then recharging the battery to full, the battery has gotten significantly better. I'm trying to drain it again before I go to bed tonight but I don't think I'll make it.
I played the entirety of Toy Story 3 on max brightness, and only burned 20% of the battery!

What's your overnight battery drain with CM7?

Just curious what everyone's overnight battery drain was using CM7. The lowest mine will go is 10% over about 8-10 hours of non use, only one gmail account syncing, nothing else. This is using every variation of CM7 (stable, nightlies, and weekly's)
Using the new 2.3.5 fruitcake I am get a consistent overnight drain of only 3%.
I have tried everything possible to match that, but I'm beginning to think it's not possible.
i only have facebook but log out when i go to bed yet my phone still drains at least 10 percent every hour haha
I'm loosing also between 8 and 10% of battery overnight. I tried to optimize it in anyway including reducing brightness, deactivate services etc but still the same result. This is something which I hate with CM7 previously I used SGS and I had the same problem there. I don't know if it is a general CM problem or just these two phones.
Strange

That's really weird. Ever since I've started using different versions of CM7 I've averaged 2-3% drain overnight. This was both on the stock kernel and faux's enhanced stock. Only thing I would do before bed is turn airplane mode on.
Lately, it's been 3-4% drain overnight but that's probably because I've been installing a lot of apps (Can't pass up those $0.10 deals). Even after switching to Clemsyn's 1.0GHz kernel I'm getting the same amount of drain. Have you guys tried flashing a new radio or setting up SetCPU profiles?
Attached pic is with a little over 2 hours screen time.

I imagine the op is not refering to stand-by in flight mode. Personally, if the phone is in flight mode sat at my side while I sleep then I might as well switch it off.
My battery drain is probably around 15% over 10 hours on Ba2tF, Faux enhanced stock. That is with 3G on and background data, including syncing gmail/contacts etc. It is certainly higher drain than I would like and was getting on stock Froyo.
However, I think ~2 days standby is not ridiculous - 1% per hour will get you over 4 days which I think sounds reasonable. We all fall foul of spending hours of our time trying to squeeze a bit more life out of our phones but most people reviewing them these days are quite understanding: "the battery life was OK - it got us through a day's use"...
Yes I agree but we have a great large battery and still can't get better life. Is it the CPU draining the battery so much? When I'm on 3G and using the phone actively during the day the battery last for no more than 10 hours. There should be a reason why the CM7 is draining the battery faster and this is what wir are trying to realize. If it was 10-15% more than ok but it is almost 50% more than a Stock ROM

I'd agree except I use my phone as my alarm clock , but point taken. Without airplane mode it would be 5% tops.

It seems that new build of GB gets pretty awesome battery life compared to most older builds or custom roms. I believe Nottach pointed this out when he initially started playing around with it for Darkside. If you haven't tried re-flashing your radio, I would definitely give that a shot. (should be in the OP of the CM7 thread)
I don't think that flashing new Radio will solve the problem. CM7 doesn't come with Radio anyway. Initially I though that the problem is in RIL but after suspending all the data transfer for a night without any change I'm not so convinced that this is the problem. Unfortunately the CM7 mail client is also not perfect and after removing it I'm getting slightly better battery life.
Just for the information.
I loose 3-4% per night (7-8h) in airplane mode.
Weekly 3, Clemsys 1.4 Elite version with a more aggressive memory timings, set at 1GHz and UV with SetCPU .
Good for me.
3-4% in Airplain mode is not an option. We are trying to figure out where is the leakage. I'm pretty sure that it is a common for all CM7 branches.
I lose 1 percent overnight with everything off. No wifi or data is on and nothing syncing in the background. I have never had a phone with such amazing battery life. Not even the old Nokia 3310 or Sony Ericsson K800i compare to this. I am pleasantly surprised.
