Hi guys, I love my SGS, but the battery life is killing me!!
I've tried 3 different ROMS, but all pretty much the same. I'm now on the 'official' JP6 / JPM. Phone is rooted, and One Click Lagfix running.
Display is set to minimum.
I sync an Exchange account using push. I've turned off gmail and facebook sync.
Using LauncherPro.
Basically, I unplug the phone from the charger at around 7am, and by 5pm it is dead!!
!!
Any suggestions!?

1: change your push-settings for exchange to 30 mins or an hour ( i did too , its better )
2: buy a extra battery
3: bring your charger to work
4: stop playing non-stop with your phone
to sum it up. we cant tell you what u are doing wrong with the small info u gave. you dont give % of battery usage ( liek 60 % display, 20 % standby etc )
all in all, i can say atm. stop push-mail
( i have same prob , i just leave my USB charger @ work lol)
root it again.
Also set phone to 2g mode rather then 3g and install juicedefender with nobars too.

There is no proof that 2g eats less battery

2g relly eats less that 3g. But i'm use both + wifi at home + look a flash video, get rss every hour and phone lives 36-48 hours on one standard battery. Maby your battery is dead. Replase it

Do it this way:
Make the phone empty.
Charge it all night (8 hours + ).
While still charging, open applictaion: Terminal Emulator (it is available on the market for free)
Write:
su
rm /data/system/batterystats.bin
it looks like that nothing really happens, but it does.
Reboote the phone. Important!
You will see the difference. I get from 1 day before to 3 days now.
For doing this, your phone, of course, should be rooted.

eh?
what would you like as a proof?
sure if you live under the antenna consumption may be the same, but 2g is much less processor intensive and has longer range.
so your phone works half as hard in 2g than 3g (both idle and on line)
with just 2g and only using phone features i can go 5-6 days
same usage with 3g goes down to 3 days
and that is with having mobile data off in both cases
2G eats muuuch much less battery. I didn't have 3G for a few weeks, huge difference in battery life.
I use Juicedefender just so that nothing goes on with my phone while the screen is off, only update rss/weather/sync when sync is on.

Can anyone confirm if this method works?
(On a side note: I'm looking for someone who can help me flash Korean firmware onto European phone so I can get "record call" feature. Thanks)
I manage to get 3+ days of battery time... I have data connection inactive, no syncs, and using a black theme Battery life just improves over time, after like 5 or 6 cycles of charging.
I've had my phone for a little less than 2-3 weeks. While my battery has gotten better with a few full discharge/charges, I still haven't reached those insane battery life times that some have had the luck of having.
I've done the full discharge method a few times. I've also done the "charge (on), unplug, charge (off), turn on for a few minutes, turn off, charge (off), method twice.
I have juice defender to set to keep everything off and only connect for 1 m every 15 m. I have root, but I've removed lagfix.
Yesterday night, I slept for around 6-7 hours. My battery life dropped a full 40%!
Here are my battery usage stats:
Display 44%
Cell Standby 20%
Android OS 14%
Phone Idle 13%
Android System 5%
I'm wondering if my phone or battery is defective and I should ask for a replacement?

Hey, try the 5min evey 2hours, that's what i have and i don't have any issues.
Obviously something is wrong. THis happened to me before, it was because of FB and google sync as well as the widgets constantly synchronizing and using mad data.
Welcome to the SGS.
Typical usuage for my SGS:
0800 - alarm used to wake me up.
0805 - disconnect from charger - full battery
Sync: K9 Mail - once an hour, headers only or messages less than 2Kb.
JuiceDefender: Data connects 5mins every 30 mins, otherwise 3g radio or wifi is deactivated.
Average time on 'phone calls: 10 mins.
Wireless use in work: 20mins max
3G/2G usage: 20 mins.
Brightness set to lowest setting.
Doing the above will empty a fully charged battery by about 1800, or usually sooner.
9 hours of use until empty, when the 'phone is predominately on stand-by.
The wireless and 2g/3g data radios are a real killer. With the data connection of, then I can watch the whole of the Avatar film on the device, and even have some power left over from some 'phone calls.
Solution: Don't use the SGS for data while not running from the mains power. It'll save the battery.
So, don't use the SGS for business. Its an expensive toy that pretends to be mobile, because really one it tethered to an electricity socket. Welcome to Android 'phones. Other than the lag that causes the 'phone to be unresponsive for a couple of mins, I like the device.
check your apps, I used to use widget locker and it'd drain about 30% a night. I dropped it even though I used to love it, I think they pushed out a bad update 2-3 months ago and never made it better.
Hrmmm, I don't have any out of the ordinary apps running. I've made an effort to check all apps and ensure they don't auto sync/auto - update or do so very rarely.
Apps I have:
Juice Defender
AutoKiller Memory Optimizer
Facebook
Whatsapp
Yelp
Uninstalled Tango
Uninstalled Samsung Apps
SMS Time Fix
The rest of my apps are either stock or don't use internet
At some point I shall do a factory reset and start again.
* In most phones when switching from 3g towards 2g will result in +1/3rd increment of batter-life
* Extra launchers(UI) will play a lot with your battery, best is to have only one running, not TW along with launcherpro
* Turn OFF the gps cos i noticed, by keeping it on, that it's a huge drain on the batterylife.
* check apps and be sure none will run in the background with adds (remove them with an add remover)
* flash to jpk and root with oclf, many complain about their roms, but after 130 apps and a month mine is still working splendidly, with maybe and just maybe the lagg once a week. (could be titaniumbackup at that moment)
downloaded a thing and send a few messages and it's at 85% atm, that's after +6 hours of use. (it was at 98% after 4 hours with a few uses)
Ok guys, Dark Steel JP6/JPM, hardly any apps, 1 Exchnge account.
I took the phone off charge at around 10am this morning, now at 6.30pm, down to only 16% left!!
Stats:
Display - 77%
Cell Standby - 17%
Phone Idle - 6%
I don't get this, the battery life is awful!! I've hardly used the phone today. Display brightness is set to absolutely minimum. 30 second timeout, and hardly used, so the screen has hardly been on!
Apps I have:
Flash 10.1
SetCPU
Remote Desktop
LauncherPro
Smart Keyboard Pro
ROM Manager
SGS Tools
Spare Parts
Plus the normal Maps, Navigation, Flash.
GPS Off. 1 Exchange account set to Push. Gmail sync turned off. Bluetooth used for around 30 minutes.
Please help me!!!! I've tried 3 different batteries by the way, so it's not that!
How many charge cycles does it need to sort itself out after deleting battery stats (deleted via clockworkmod recovery)?
Thanks!!!!
Your phone idle is only 6%, something is stopping the phone from sleeping. Give us the reported times for display, idle, e.t.c

I've updated to DOC & Kalpik's new v6 from 5.1.1, and charged 100% before I went to sleep. In the morning(6,5 hours) the battery was 79% with screen off, wifi on(never sleep).
Even if wifi was on, I don't think it's normal(3g should eat more), so I wiped the system. Now I'll put the applications back day by day, and let you, and other people know what eats the battery.
Okay, a bit of an update:
If in 6 hours battery dropped 20%, battery should drop 3% in 1 hour. I was letting phone alone for 1 hour, and battery dropped 4%!!!!
Completely new system, it's newly wiped v6. Spare parts says: running 30%, screen on: 30%. No app, that uses cpu too much.
Installed applications:
- Spare part, Swiftkey keyboard, Astro, Battery indicator, autokiller.
wifi on : never sleep. Stock adw.
Any idea what eats the battery? I just wiped the system from clockwork!!
Froyo, that's what.

Is it?
With Doc's rom it shouldn't be a problem. It's highly optimised to battery consumption. I remember having version 5f of that ROM, and battery life was excellent! I don't know what happened...
1% battery drain every 3 MINUTES
One more thing I have to add:
I have 1% battery drain every 3 MINUTES if I'm browsing stock browser. Now that's waaaaaay too much!
What I do wrong?? Or is it normal?!

Battery life
I managed 6 days straight hehe with old style phone use, no gaming, no serfing, just 5-10min call time avg per day, a bt headset connected 5hrs avg per day, screen brightnes set to auto. Just once connected over wifi to download 1-2 apps and 10mb files. Fully charged on Saturday around 1pm, empty battery today about 2pm. While idle the battery drops 1% every 6hrs.
Won't do it again though, cause this is not what the phone is made for , i realy missed it during this test
You will get 1% per 3 minutes of high cpu and screen use (browsing)
It ends up at about 100-0% in 5 hours
That is what I usually get out of my battery on all firmwares, watching video's last longer though, 6+ hours
Sent from my GT-I9000 using XDA App
i have the same problem...
last week when i was testing doc/kalpik's or 2.1 rom i got 3% out of 6hrs standby.
last night it drained 25% on sleep! (maybe sleep is disabled somehow? or a tweak that is preventing it from sleeping properly?)
anywho.. before all this happened i noticed that the phone started to lagg (not the normal pause or two.. you could not do anything without it lagging..) it started to drain the battery (1% every 1-2min, screen on but not doing anything).. it went back to normal when i disabled usb debugging mode.. (very strange)
maybe there is a fix to this?
cheers
My battery drains ready and if I unplug it at 6am it won't last me past 4pm. I use my phone lightly mainly just texting. On the battery usage app it says 92 percent beside the display. I use the lowest setting for brightness. I currently have andromeda 1.0rom on my rogers captivate. Previously I had the cognition 3.04 but still the same problem. I've tried deletingbattery stats through recovery menu. I also tried calibrating the battery. Wifi is used instead of mobile network. Gps is off. Bkuetooth is off. Emails set to push (i read somewhere that push is more energy efficient than autosync)
Could this be a hardware issue? Any idea on what I should do about my problem?
How much actual usage does your phone get? 10 hours of battery life is abnormal unless you have like 4 hours of screen time.

Well you can check your screen time by going into the battery stats then pressing Display.
Other than that, it'll tell you how long you've used voice calls and stuff as well.

You can check your actual screen time by tapping the "Display" entry in the Battery Use screen. That will tell you how many minutes your screen has actually been turned on.
I have a similar problem: My screen seems to use a TON of battery power, and it's almost always over 93% or for battery draw. I don't see a huge difference in power use between minimum brightness and automatic.
I tend to use the internet and text/email heavily, but I'm wondering if even that could account for the insane battery use. Today, I unplugged my phone at around 6:40 am. By noon it was at 1%.
Before I started using custom ROMs, I could usually make it to 4 with what I considered heavy use. Now, I can't make it past lunch time. I've done the battery calibration, bump charging, deleted battery stats, and discharged the battery to shutdown before charging fully. The screen power draw has persisted through two ROMs and three kernels. I'm wondering if my usage pattern has just changed this much, because I can't find any hardware or firmware issue to account for this.

Yea our problem is pretty close, if not then identical. I'm using it moderately and its at 10% right now.unplugged it since 6am. Ive tried a lot of different methods to try to fix my issue to but still nothing.
A few minutes ago, I checked my battery use. Here's how it played out:
Unplugged for 58 minutes
Screen on time 28 minutes 3 seconds
84% battery left
92% of power used by the screen
Do these stats look normal for screen power draw? This is what I'd call heavy use (I've been reading forums), but should the battery be draining this fast?

I have no idea. thats what i want to find out. heres mine...
66%battery
9h27m52s since uplugged
display - 76% --- time on: 1h23m22s
wifi - 13% --- time on: 9h26m51s
cell standby - 8% --- time on: 9h27m42s
phone idle - 4$ --- time on: 8h4m29s
any idea? i slept at 3am and woke up at 930, but didnt charge the phone.
Before i slept the phone was around 72%, and when i woke up it was around 70%. from the time i unplugged it to the time i slept it went down from 100 to ~72% under moderate use.
are these numbers right to you?? the only thing i am worried about is my display consumption that seems to be killing the most. Also, wifi uses less battery than 3g/edge right? so i shouldnt have a problem leaving that on. even when im not using it.

That seems like regular battery life there. If your phone is reading your battery accurately, that means you would be getting almost 30 hours with pretty decent usage before it dies.

Here is another update. tell me what you think.
29% left

6% on cell standby -- 13h 13m 40s
3% on phone idle -- 10h 21m 4s
It doesn't even show me my voice calls and 3g usage. weird.
also, do you know if the timestamp on you batterystats.bin is supposed to change? is that normal? or does it mean my batterystats is wiping on its own?

I believe the timestamp is supposed to change with batterystats.bin being updated. The only way it is wiped is if the file is deleted completely.
And still, that seems about right to me. 3 hours of display is a fair bit. In a regular day I normally see about 30 minutes of display usage.

wow really? 30 minutes of display is like bascially not touching the phone at all.
Is there a reason why the battery usage does not show my voice call usages and my data uses (mobile data, not wifi)
I feel like my battery life is... Less than ideal.
I'm going to be doing a few tests, unfortunately, it seems like my battery dwindles very quickly in 30% chunks, according to JuicePlotter.
One thing I've noticed that helps a lot is disabling your data network in general, unless you plan on using it.. You can still send/receive texts and phone calls, and that's primarily what my phone is for. It helps save a significant amount of battery.

Unfortunately, because I am waiting for some emails i cannot turn off my data network. my data network is on when i cannot get a wifi signal. I also feel that this battery is not ideal. I cannot last for more than 10hrs unplugged time if i unplug it when i wake up. if I unplugged it before i slept it would be a different story for obvious reasons
again, any help is and will be greatly appreciated
Here's more stats (running Cog 3.04, Gen X 1.14 theme, stock kernel)
Unplugged for 16h 22m 40s
69% battery life
38% display: 41m 24s
23% voice calls: 29m 39s
21% wi-fi: 16h 22m 40s
13% cell standby: 16h 22m 40s
7% phone idle: 15 h 41m 16s
It seems like I can easily get around 40 hours of battery life here, but obviously I'm in the light usage market, although I do use my phone to make a lot of calls.
In the past, I found that running different modems and kernels (specifically DG's Firebird 2 kernel) drained my battery life faster. While I loved the extra power and features (Voodoo sound specifically) the drain on my battery life was not so hot (see above specs but my battery percentage would be closer to 30% than 70%). I recommend returning back to stock via ODIN, see what your battery life looks like, then adding a custom ROM, seeing what your battery looks like, then kernels, then modem. That way you'll find the source of your problem. If your battery still drains heavily on stock, try a different (possibly new) battery. If its still doing the drain, it's gotta be hardware related and you might need a new phone.

Interesting, I was at 18% battery after 2 hours 45 minutes of screen time. 93% screen, 3% wifi, 2% cell standby. I'm starting to think that a) the screen really does just use a lot of power and b) my battery is becoming deficient.

I was actually thinking about returning my phone back to stock, unfortunately i do not know how to do it. I came across the odin3 one click downloader, but i was told by some to not use it since it is for AT&T. I am from canada and I use Rogers. Any ideas?
Does anybody experience a 3% to 5% battery drain just a few minutes after charging the battery to 100%? It has already reached 100% so I already unplugged it from the charger, but then I noticed after a few minutes, it went down to 97% already, and then in 10 minutes, it's already down to 96%. In 3 hours, it's down to 84%; in 7 hours, it's down to 38% and that's just on standby mode with Wifi/Bluetooth OFF, 3G OFF, GSM only. I've been experiencing this problem for the past few days now. I've already conditioned my battery, charging it to a full charge (100%) after draining the battery until it shuts the phone off. I only charge the battery while the phone is off and usually it takes about 3 to 4 hours maximum to charge it to 100%.
The longest time it reached was 12 hours (battery unplugged from charger) and that is with light use, such as Wifi is only on for a couple of hours, so basically just 2 hours web browsing and skype, 10-20 text messages and 30 minutes to 1 hour browsing the photo gallery or watching videos. No phone calls and 3G is off. The rest of the day, the phone is just on standby mode. I only have at most 10 widgets on the home screen. I have Avast Antivirus running in the background.
I am currently using Easy Battery Saver, Easy Task Killer, GO Task Manager and Battery Monitor Widget. I've uninstalled Juice Defender since I don't think it helps that much when it comes to the battery drain. Currently, the power saving option (available on Note) is enabled at 50%.

Any feedback or comment on this matter would be really much appreciated. Thanks!
From a personal standpoint. Your screenshots shows that your phone had never ever done a deep sleep at all. the 'Awake' mode is continously consistent as well. I guess the probable reason for that is you've installed ''Avast AV" on your phone. It's always running in the background (whenever the phone is ON). From my experiences, Any background application running would always cause wakelocks and the phone would never enter into deep sleep at all.
How bout you try uninstalling some of the background apps your using esp. Avast AV and give it a day to observe if your still having that battery drain issue. (Don't forget after uninstalling or removing those apps, try to wipe dalvik cache and battery stat and restart your phone after.)
and Oh by the way, I am using Juice Defender and contrary to your saying it doesn't help.. IT DOES HELP save battery as I my Note is able to reach 1.5- 2 days of normal use.
Cheers!
Yeah and download betterbatterystats and do some searching on it. With it you can discover what is causing those wakelocks. Search the web for more info on your wakelocks.

I'm using avast and never seen a drain like that. Only time I have is because of background processing. First thing I would do is turn off Background Data
Then as others have said - check batterystats to see where wakelocks are
Plus a rooted phone is a good thing. Titanium backup allowed me to freeze wi-fi sharing which also made a big difference
Finally - clear all caches from Applications menu and reboot

Only picture that shows that is the one with 1 minute 56 sec discharging time, so it was taken shortly after taking charger out. No suprise of it being almost 100% screen on time there if its only 2 minutes
Also installing "cpu spy" will give the cumulative time that your cpu spent at each frequency including deep sleep , mine is showing 88%
John.
Anti virus app is battery hog, I had avast before too, and I uninstalled it after 2 days using. Also that Juice defender, from my test before, it use up more battery than it saved. turning on and off those 3G/Wifi thing is using up alot of battery. and you know what? even the betterbatterystats use up alot, at least to me, becoz it scan what is up frequently.
Hello! Thank you all so much for your response. I've installed both BetterBatteryStats and CPU Spy and here are the results (please see attachments). Upon checking CPU Spy, it shows there that phone did went to deep sleep, maybe? I'm not quite sure, but it shows on the screenshot that it went to deep sleep for 19%. So does that mean the phone really went to sleep?? I'm sorry to ask this question, since I've never really encountered this problem before with my previous Samsung Wave phone, how will you know that your phone went straight to deep sleep mode?
Also, after 46 minutes or so, the battery went down to 96% already after charging it. The battery drain was already 4% in less than an hour.
@letters_to_cleo: I have not uninstalled Avast yet, since I'm still hesitant to use my phone without an AV. But I will try your suggestion for 1 day and see if there's any battery improvement.
I'm looking forward to your response or suggestions. Thanks again!
i am having problem too with new battery original samsung ( made in japan, finished in korea) previously i use samsung battery made in china, finished in korea. charged it over night with power off. it only last 13hrs. my wife phone can last 30hrs.
i've used batterymix to check the battery usage graph, the usage graph drop very fast compare to my wife phone. i'll post some screen capture of the graphs.
another issue is i used once wifi sharing. after turning switching the wifi sharing off, the wifi sharing service always at the background even after many reboot. how to turn that off??
You might need a new battery. Any rechargeable battery has a finite charging cycle. Just a suggestion.
Hi, all! I just noticed that the battery drains still even during deep sleep mode. After 3 hours or so (during sleep mode according to CPU Spy), the battery went down to 92%. It drains even faster when the phone is in use, especially when Wifi and Bluetooth are on, maybe 2-5% drain in 1 hour.
Maybe there's something wrong with the battery?? It's still a new battery and I can see some improvement each day though, but that's because I use it less each day. Before the battery can only last for 8-10 hours, then it increased to 12 hours, and then to 16-17 hours. BetterBatteryStats' current estimate to empty is 24 hours as of today, but that's because I only used the phone today for only a couple of hours, with 20 minutes Wifi and Bluetooth ON and most of the time, it's on deep sleep mode according to CPU Spy.
What do I do with the results from the Partial Wakelocks? Do I have to disable those apps?? The Kernel Wakelocks didn't show any reference apps running. The screenshots for the Partial and Kernel Wakelocks that were taken a few hours earlier still show the same results after 3 hours.

That would be really bad luck. I got my Note via preorder in Germany at the first day it was sold and since then I charged it everyday, sometimes even twice and there is no difference to the first day. If I get told by Samsung after 6month of normal usage the battery is dead that would be the last Samsung device I bought and I use a lot of Samsung stuff.
@ebichan24
Your last screenshots show between 9:35 and 13:35 5% of battery drain. That's not really a good value but ways lower than before. Did you delete some Apps or what did you change?
And since when occurred this issue? Did you install new Apps before this happened?
On my Note I had this issue sometimes without any changes but it was gone after a reboot.

Agreed with Kanalcommander.... try a reboot in the first instance.
Others have also noted that it takes a few refresh cycles before the phone more accurately reports battery use. Perhaps what you are reporting is because the phone and battery are new (new ROM or Kernel loaded?)
What I have done in the past is to reboot into CWM recovery then clear the battery stats (in the Advanced menu option) Recharge the battery to 100% until it says to remove charger and then use normally until battery down to around 20%, then recharge the battery to 100% again. Do this over a few days and that may help.
thanks, it is new battery two days old.

I was having similar problems with my new note and finishing full charge in 12 hrs but fixed some things and my last charge gave me 2d6hr seriously..few things i did were stop using live wallpapers! Get badass battery to thoroughly monitor stats and then use zdbox to extend life even much eg. I put phone to auto flymode using that app when its sleeping time rest i am more than satisfied even if on GB LC1 fw..waiting for official premium suite for ics since i recently upgraded from sgs2 using ics i miss that smoothness and much better bat life.. Let me know if can be helpful.. Good luck

@TempusFudgeIt
That's what I'm currently doing right now, well, actually, what I do is I discharge the battery until it reaches 0% and turns the phone off. And then I charge the phone for 3 hours while it's switched off, I turn it back on again to check if the battery is fully charged and then I unplug it from the charger.
@Kanalcommander
**Did you delete some Apps or what did you change?
I haven't deleted any apps yet since I don't know which app/s to delete. Most of the apps I downloaded in Note were the same apps that I used in my iPhone4 and Samsung phone before.
**And since when occurred this issue?
This issue occurred since the first day I bought the phone, which was a couple of weeks ago. How long does it take to condition a new battery and new phone?? I'm sorry if I have to ask this question, it's just because I never really experienced this problem with my previous smartphones.
**Did you install new Apps before this happened? On my Note I had this issue sometimes without any changes but it was gone after a reboot.
I only installed recently CPU Spy and BetterBatteryStats and that's it. The drain of 5% from 9:35 to 13:35, the phone's just on deep sleep mode. And then from 13:35 to 23:44, it went from 92% to 74% while the phone is on deep sleep mode at 90% according to CPU Spy. That's 18% battery drain. It's just an unacceptable number for me. I tried rebooting the phone already, but every time I do so, just a few minutes after I turned the phone ON, there's already a 1% drain in the battery.
Also, does the battery really drain faster when the Wifi is ON? I've read in other threads that there might be some problem with the recent OS update that Samsung needs to address. Is this true?? Because as you can see on the screenshot below, the battery was still at 74% by 23:44 and then after I turned ON the Wifi and used it until 01:26, the battery went down to 54%. That's already a 20% battery drain in just less than 2 hours. I was only browsing through the Android Store and Skype.
Calibrate your battery in case you flashed any roms and for first usage I got my battery to 0% 3 times then everything is running great for example its at 47% now its 22 now and I have had it off charge since 7 morning..... i have wifi gps and 3g always on and use music player bluetooth and made some calls

My battery (also only a week old) drains quickly too. Can anyone tell me if widgets draw a lot of current? And then is it only the ones on the visible screen or do all widgets draw juice all the time?
I will ask such thing, did you guys check the battery expiration day ? Mostly sibce you got your phone almost a yeae after it was announced you nay get a bad battery, as for widgets the ones that are always active and asking for informatiom. Like location or weather over the internet yes they do eat your battery kinda fast.

Recurring battery drain? - Caused by memory of using app to drain battery?
Hello!
I used a battery drain app when charge left was 30% to accelerate drain to "die out" stage. After I completed the calibration process for unrooted phone as suggested in various sites (charge fully, switch off and charge etc.) I started using it from a 100% stage.
This afternoon when the battery showed 30% I saw in BMW the current flow was in -10ma to -15ma and it started spiking to hundreds. There was no change in settings or usage. From the 30% level it dropped to 10% in an hour and I had to charge again.
Was puzzled why the battery which was dropping around 0.5%/hour in standby earlier to the 30% level suddenly went down hill. My first guess was it was possible some file in the system remembered the previous usage history and replayed it out.
Any suggestions? Anyone faced this before? Everyone says LiOn batteries dont have memory so if anything it has to be the phone.
Thanks!
Hi all
I tried to cut battery consumption down as much as possible while phone is in standby/deep sleep.
I now manage a drain of around 1%/h (BetterBatteryStats actually reports 0.9% per hour).
This is with Wifi on, everything else turned off. I have my CPU undervolted by -100mV and am using perseus kernel with RipperRom, Radio is currently LL3. The signal coverrage in my area is good (3-4 bars).
What is your drain when the phone is not in use? Best way to check is to fully charge and unplug the phone before going to bed and leave it alone until the morning. You can either calculate amount of battery drained per hour yourself or just use BBS.
Please also mention your configuration (Rom, Kernel, Radio, Undervolting, what Antennas were active during standby and how your reception is)
mine's about the same, 0.8 - 0.9%/h on a good night. CPU undervolting won't help much as the phone hsould be in deep sleep most of the time (CPU UV is only active when the phone is not in deep sleep). my wifi is on 100%, i have a bunch of push accounts, a few pull. using ripper, perseus, default telstra modem, good reception
Not rooted, but overnight mine tends to drop around 5-8%, this is with everything off. I had the HTC Sensation prior to this phone and that practically lost no battery life when on stand-by! So am a little surprised it drops quite a few % from stand-by mode.
yeah that's pretty bad, I would get BetterBatteryStats and work out what's chewing up your battery. I'm pretty sure you don't need Root unless you want to look at the network or process stuff..
I'm using Ripper ROM V8, Latest perseus kernel and LL5 Modem.
I got 3% drain overnight (9.5hours) with wifi and data off.

It might be that location reporting is turned on. You should check if google maps has "Report from this device" activated. If so, it will constantly wake you device and report your location to who knows where. I have turned it off and my battery life has vastly improved
However, 5-8% in a time span of around 8h seems normal. You will only achieve less if u switch off wifi and data
