Battery Drain HD2?

Anyone else experiencing excessive battery drain on their HD2?
I am interested to know if this is just my phone or if it actually just chews through that much juice.
I have had windows mobile phones for several years so I know all the basic ways to keep battery drain down.
Stuff that I have generally found:
1. If I keep the screen turned on without it going blank I lose about 1% every 2 minutes.
2. If I am browsing that figure almost doubles.
3. My old Touch HD used about 5% battery overnight when in standby but this phone will go through about 25%.
4. The phone gets really hot when browsing (much hotter than my old Touch HD)
I have tried flashing ROM's and Radios but nothing seems to help.
I am not running any software on the phone that I wasn't running on my old HD1.
I have only had the phone for a week so I am not sure if this is normal but I would be very surprised if HTC released a phone that lasts for only a few hours on one battery.

+1
-1% every 3 minutes
-4% during the night (when i'am sleeping)
MAXIMUM : 45/48 HOURS

I wish I got 2 days

we really need extended battery ,hd1 battery was much more better.

Good mate but yes i agreee HTC has come up with a battery eating device this time around. My device on full charge just gives in around 8-10 hrs. This might be dat my EDGE is on and 7 mails accounts sending mails back and forth.
but truly i think that HTC better look into this very seriously cause more and more ppl are suffering in this battery drain..
Any of flashing roms and radio not helping either... did a complete hard reset but no step up
HTC come with longer battery battery for bigger devices soon......
The only solution i see now is get one of those extra battery worth mind bogling £52.87

I've had this problem ever since flashing to 1.66, I flashed the radio to 2.07.50.27 as this was said to solve the problem but it hasn't made any difference after a few days of use. My battery life used to be significantly better when I was on the original stock ROM, so much so I'm considering going back to it
I also know all the tricks as to clawing back the battery drain, my phone is idle on my desk at work most of the time and I don't use Wi-Fi, all the location stuff is turned off as are weather, stock and other updates plus my screen is set to 30% then off after 60 seconds. Despite all of that I lose 1% every 2-3 minutes
It seems to me that perhaps the radio is checking for reception pretty much constantly rather than say, 5-10 mins perhaps? This used to be a problem on my old Blackberry Storm but a few fimware updates solved it, eventually!
The only other thing I've noticed since the update is that once the battery drops below 50% or so, the drain seems to slow, I don't know if this is perhaps because the phone goes into some sort of semi-power saving mode?
Suggestions/hints welcome! I've had a semi-thorough look into this on the forums and tried most of the suggestions but still the problem remains. Will battery life improve after a few charges perhaps as this was a trait of my Storm's battery, the more you charged it the better the day to day battery life was (and no it wasn't because I had it plugged in all the time! Over time the general charge just seemed to improve when roaming).
Thanks!

You need to indicate what services you have running. Do you have any data services running eg: location services, push mail, weather? all of these have a bearing. In addition, network services can also drain a battery, especially if the signal is weak and the phone have to search for a transmitter, or 3g services.

That is a very interesting comment. Although since upgrading to radio 2.07.51.05_2 I have had very good battery life, I too have noticed a slowdown after 50%

Nothing is turned on, everything is set to manual.
As I stated I know all the basic stuff. I understand that all these things have a bearing on battery loss.
Everything I stated in the first post is for when I have nothing running. The phone is just sitting there running sense, thats all.

I have had my HD2 for a few days now. I am on Vodacom in South Africa.
I have not had a problem with battery life.
Yesterday i unplugged from the charger at 07:00. I spent about 1 and 1/2 hours of talk time on the phone, it was permanently connected to 3g doing weather updates etc. Sent and received a couple of sms's. Also played with a few tweaks and reboots.
When i got home at about 18:00 i had over 30% battery. I then surfed the web for over 2 hours to drain the battery.

try setting Network Selection to Manual

Same here with and without stock ROM.

yeah.. the phone is a battery sucker.... another cons of HD2....

This is very interesting to read because I do not have this problem. When I left my HTC HD2 on last night (I woke up at 4 in the morning to get something to drink and unplugged it) and then woke up at 8, it was at 98%. That means it went from 100% to 98% in 4 hours. Not to bad imo.
I am now at work and it is 15:34, and I am at 87%. I have made some calls, watched some videos, send a few text messages. Not much (I am at work so I got other things to do). So 08:00 (98%) - 15:34 (87%) - that's 7 and a half hours, with some calls, text messages and a video.
I am pretty sure when I get home at 18:30 the battery will still be above 75%. Then I connect to my wifi at home, refresh twitter, weather, browse the web a little bit, check e-mail etc. So that will drain my battery a little more.
But overall I have not had any problems with my battery life. I always make it trough a day, and never have a problem like 'damn my battery is almost done and I am not near a charger'.
Some info that might help:
I do not sync ANYTHING automatically. I still have some things to do with my Vodafone contract and do not have an unlimited plan yet. I only sync at home on my own wifi connection. For me this is not a problem, because I only need to refresh the weather each morning to see what the day is going to be like. Twitter I only do when I have the time. Stocks I do not use.
I have screen brightness set to automatic.
I am on 3G most of the time.
I am running the official 1.66 Dutch ROM.
I have some tweaks, games and programs installed.
I hope you all solve this issue, because it just can not be that my HD2 has a good battery life, and your HD2 not
Kind Regards
EDIT @ 17:00 still 87%.

I am in a 3G 2100 only network (I don't have 2G functionality).
ROM: Artemis 3.0
Radio: 2.06.50.23_3
Customization: Seiya 6.5.5
I don't leave any automatic updates on, except for my e-mail account every 2 hrs.
I never close my connection.
The drainage overnight is -3% (8hrs).
The battery lasts at least 12 hrs of intense usage.
Normally I have to recharge every second day (e.g. I charged last night, I answered a few calls, I did some IM and browsing and I still have 73% left).
For a phone with a 1 GHz processor, a 4.3" screen and a tiny 1250 mAh battery I find the drainage is rather decent.
Mind you, I ALWAYS do at least one full charging cycle to my battery after flashing a new ROM. I mean: full discharge, battery out 1 min, full charging in OFF mode, battery out 2 mins.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?

maybe its also becouse some of us couldnt wait using the hd2 when they got it (like me) before it was fully charged for the first time
anyway my battery life has improved a little bit, i was at 74% this morning and did a lot of browsing, installing, tweaking and now its at 3%. it used to be much worse

I have battery consuming problem from time to time.I did everything:
installed new stock rom 1.66;
transfered all data which phone is using from card to phone memory(pictures,icons,sounds.etc...)
all updates are done manually;
Gprs connection is swiched off on the idle after one min;
One night it is loosing from 2 to 4%;
another from 30 to 40%
and it is eating memory from 10 to 15mb
I think that it is radio which is causing battery drainage so fast(to much communication wit a base stations,because when I am checking spb wireless monitor in the morning,there is no any data traffic.
I hope they can solve problem,because it is getting me mad and crazy

Try setting the screen brightness to 10-20% (on battery powered)
and dim backlight after 10 seconds (on batter powered).
It helps a lot, at least for me.

as far as i know, the battery has an integrated digital circuit (ic) which estimates the state-of-charge (soc). the procedure resets/calibrates the ic to obtain a more accurate estimation. since the radio rom is in charge with the power management (among other things), by changing it you decalibrate the "gauge".
i don't know if i've got the theory right but i tested this myself and it surely works.

What is your display power drain?

Maybe my battery is not trained yet, but so far, on my 2-days old n1, battey lasts for 4 hours (mid. backlight, no wifi, very little use).
Still running stock rom and not planning on rooting.
What I noticed is that in my battery drain stats show Display contributing to 80% of total drain. That's with display being on mid setting... is that normal? What is yours (esepecially for people with stock roms)?

Are you playing with the phone a lot? Like is your display always on? 4hrs still seems extream to me, I am rooted and runninng a custom rom, but even when I wasnt I never managed to get through the battery that quickly, and I use the phone a lot

Here's what I do to get good battery... I only keep backlight on like the a ****as hair..lol barely unless outside...... widgets are cool n all, but if there constantly updating thats polling your battery, live wallpapers are cool, but a battery drainer, I also keep gps, locations and bluetooth off unless using them, wifi also.. also the background applications setting uses battery but if ya want updating widgets no way around that...
Also look in seetings about phone, battery use and see what's eating your battery, I use my phone hours at a time so my display is most my battery drain which is normal, everything else is like 7 percent or less, mostly 2 or 3 percent. ....
I think thats all I do, but you may keep stuff on like widgets and that unfortunately eats battery..

I am running everything in my Sig. I have had my N1 for about 2 months now right around that. After a 14 to 16hr day with some heavy to mild usage I am still over 50%, but then again I have 3g turned off and i am only on Edge all the time since i am always around WiFi. So i would tell you 4 hours is a bit extreme but hang in there it does get better. I remember being around 25% for the 1st few weeks until it got better. Other wise do what Temperbad said that is the best way to go. Only widget i am running that updates every hour is my Weather one. Turn the screen all the way down unless it other wise needs to be up. I am sure that is what is killing your battery. Mine is always on the lowest setting until i am outside.

Sadly I'm rooted, but I will state my percentage too.
Weirdly, my display usage is only 15% on Paul's Desire ROM. Honestly I dont see how this may be - but that is what it says. My brightness is quite high too..

Yeah, I'm well aware about widgets and battery drain regarding 3G and all that, I've had PDAs for quite a while.
For comparison, my old and ****ty TP2 would drain about 30-40% of its battery with same usage that would drain my N1 dry.
I do remember that LiIons get better in a week or so of usage, but I wanted to hear what you guys are getting. Would love to hear from someone who's just bought an N1 like me.
It's under full warranty, so I'm not worried too much. Just an inconvenience.

I have my display set to "Auto Brightness," have a display timeout of 1 minute, have my email get synced every hour, and also use a live wallpaper.
My display accounts for 63% of battery usage.

Auto brightness will use more battery than keeping it low. Cause its constantly checking light density through the sensor to give it the correct lighting...

I agree, but disabling that, disabling GPS, WiFi, turning off 3G, killing all widgets.. ok yeah my phone will last me 2 hours longer, but it's also boring as hell.
Might as well go pick up a simple nokia for $10 - battery will last for weeks, but what's the point..
Not saying your advise is bad, it's a good idea.. just that all these advices to turn everything off - what's the point of even having a PDA then..

I've read otherwise, though I don't think that Auto Brightness is the optimal battery saving setting.
Obviously it's a middle ground between max and low.

Here's a report of my usage today:
~Wifi and 3G both turned on the whole time
~30 mins of MP3s with head phones
~20 mins of 3G tethering over Bluetooth
~40 mins of apps usage (mostly the Browser and the Gallery)
~8 mins of talk time
one 1 min update through the bootloader
have gmail sync turned on, also twidroid syncs every 15 mins
The Battery use app shows:
54% Display (active 6% of the time)
16% Cell standby
14% Phone idle
4% Wifi (active 51.6% of the time)
4% Android System
Right now 14h26' since unplugged, still having 43% of the battery left. The battery meter says 12 more hours until 0%.
All things considered, the battery life is quite good on my N1.
Edit: forgot to mention, the display is set to the middle setting with the Power widget, no auto brightness

Wow... that's some serious battery life.
Ok, some questions..
1. screen brightness setting?
2. how long have u had that phone (battery) for? Did it improve over time?
3. Is it rooted/flashed or stock rom?
4. you got any syncing widgets running (RSS/twidroid)? Live wallpaper?
Thanks a bunch for your input!

45% - Display
22% - Cell Standby
17% - Voice Calls
5% - Idle
3% - Android System
2% - Wi-fi
Just one comment. I keep Wi-fi and GPS on all day because Wi-fi sleeps when the screen is off and only polls when the screen is on if you're not using it. GPS is only used when your location is required in an application. i dont know why people are always like "you have to turn these off to get good battery life" (Notice wi-fi is 2%)
also i've been running 8 hours with moderate to heavy use (internet, music, phone calls etc) and I'm @ 40%. The drain from 70% - 40% seems to go so slow compared to 100% - 70%.

Your right... about the updating widgets and wallpaper, they do make the phone funner.. but why need gps on when not using, or bluetooth, or wifi? Just simply turn them on when using...
So much going on with this phone I can say its good pretty decent battery....
Anyone know how to make my gmail sync every hour instead of instantly?

When I got my Nexus my battery was just as poor, but after using it for a couple of weeks I'm getting about 10 hours usage with medium brightness, WiFi, and gps.
So just give it some time and it should fix it itself.

Battery issue - new question

I know battery issues have been discussed over and over in this forum, but I have a question that I couldn't find the answer to in this forum.
I have an unlocked rogers x10 that's updated to R2BA020 that I'm using on Fido network, the phone is always roaming because I'm on Fido.
I'm thinking this is why my battery life sucks. I tried everything, task killers, juice defender, dim screen, full discharge.
Does the phone use more juice if it's roaming?

Yes, but it doesn't make a very large difference. If you're worried about constantly roaming, take a look at android, which let's you turn off Amsterdam on 3G.

Have you tried spare parts or something similar to check your battery usage? It lets you see what component is using the most battery. Even the Battery Usage option under Settings->About Phone should tell you where your juice is draining.

If he doesn't want to download spare parts, he could just dial *#*#4636#*#* (did I get that right?) in his dialer to get to the same menus.

Greetings,
Yeah will be more wise to check whats actually draining your battery so we will facts in front of us and try to find a solution.
As for roaming i think yes draining more battery, please gove us usage of the phone , activity and how much your battery can hold up.
Also please onform us what home you use.
I recomend home++.

I'm still having battery life issues as well on my Rogers x10a.
I was at 100% as of 12:00pm and it's now at 87% 5:00pm.
According to the battery info I've used:
Voice Calls - 30% (10m 35s)
Cell Standby - 28%
Phone Idle - 22%
Display - 11%
Android System - 4%
ADW.Launcher - 3%
3G on, WIFI off, BT off
No idea what is draining my battery so much

I'm on Fido as well, though I don't see a roaming icon anywhere.
Are you sure you're roaming?

2.6%/hr with actual use (not sleeping overnight) is not bad at all. a 4inch screen, 3g connected all the time smartphone will not get great battery life if you actually use it. many people talk about how they get a couple of days or more on a single charge but there is no possible way for this to happen unless you are barely touching your phone. the best i can hope for is a full days use as i use my phone all day and evening.
sometimes an app sits in the background and uses lots of juice, so if you want to make sure that is not happening you might want to do a hard reset and not install any apps for a day and see how battery life it. you can add back apps slowly so that you will be able to tell if one is causing your phone to use too much juice.
the other things you can try is not to use widgets that auto update all the time or try locking your phone to 2g for the day, turning screen brightness down to the lowest level when possible. stuff like that will help. since i updated to the r2 generic rom my battery life has been good enough. i could always use more, but i use my phone too much to expect more.

Thanks I use my phone a lot as well but hearing all these awesome battery life stories had me expecting more. Guess I'll live with what I have.

It drives me nuts too but the reality is that we all use our phones differently so while some people are happy getting two days of use by barely using their phone I just can't do that. I rely on my phone for too many different things, so if I can get through one day I am fine. It was a shock for me initially as I was using a blackberry 9700 and it had a very small screen and long battery life

I took my phone off charge 6 hours ago and I have 79% left as I type.
I did a 5 minute phone call, 10 minutes browsing, 2 minute YouTube video and I turned on WiFi for 30 minutes and Bluetooth for 45 minutes.
I checked the settings and it says:
Display 48%
Standby 18
Phone Idle 13%
Voice call 13%

I've been switching options on and off for the last few weeks that I have x10 and the conclusion is => turn of APN when you don't use it and the battery last for 3 days. Only problem I can think of is mail push but you can always check mail every 30min. There is this "APN on/off" widget that makes switching APN on and off pretty easy so there shouldn't be too much problems.

Doesnt make a difference here.. wifi and 3g cane my battery!!

I took my phone off charge 6 hours ago and I have 79% left as I type.
I did a 5 minute phone call, 10 minutes browsing, 2 minute YouTube video and I turned on WiFi for 30 minutes and Bluetooth for 45 minutes.
I checked the settings and it says:
Display 48%
Standby 18
Phone Idle 13%

Update:
I removed JuiceDefender, and I installed advanced task killer, and APN on/off widget and the battery life is much better now. I turn data off when I'm not using the phone and I kill tasks about 3-4 times a day. The screen is dimmed to 15%.
As per Android system info:
Up time: 1 days, 3 hours, 1 minutes, 59 seconds
Up time (without sleep): 0 days, 4 hours, 23 minutes, 8 seconds
17 % battery life left
I checked the settings and it says:
Display 40% (time on 2h 33m 58s)
Standby 29%
Phone Idle 22%
Wifi 4%
Android System 3%
Broswer 2%
Quick question for advanced users, I noticed that Android sys info says up time without sleep is just over 4 huors while the phone settings says 2h 33m, any idea which one is more accurate? I'm assuming up time without sleep = time screen is on.

Switch off GPS. I read about it and how it improved batteries. Bloody true. Its great advice.

Time without sleep = time screen is on
IF nothing isn't keeping the phone awake.
The phone setting says 2h 33m because it counts the time that the phone was asleep AND the screen was off.
The real percentage is the one Android sys info gives you.
It is rather normal for the phone to have slightly more awake time that screen on time, as some applications work even when the screen is off (push Gmail, the clock, some widget etc...).
As long as your wake time is not 100%, you're just fine.

Thanks for the info. Good to know that Android sys info is accurate, almost 5 hours of up time is amazing.

Battery drain problem/sensor usage

I got a heavy battery drain after flashing to the official Kies 2.2 here in Norway, on JM2 I had over two days usable time, now down to a normal day.
I've reset it several times, tried running it without any apps at all, still heavy battery drain. After checking the battery statistics/history I can see under "Partial awake time", Android System, 2 hours after 14 hours "uptime". And under "Sensor use", Gallery eats up 9 hours, 11 mins. Now what the hell is that about T_T
At least waiting for the new official fw in november.. At least the GPS got better for my part, so it's not all bad

After updating to the official 2.2 that came here in Norway, I started experiencing heavy battery drain compared to before.
After some digging I noticed under *#*#4636#*#* and Battery History and Sensor Usage, Gallery is on top! And it's using the phone's sensors almost 100% of the time it's been on. So, now; the phone has been unplugged for 12 hours, 14 minutes, and Gallery has used the sensors for 12 hours, 4 minutes. Doesn't make sense.
I suspected wifi to be the culprit to begin with, as it throned at the top in the normal battery drainage-graph (about phone, battery usage), but even if I turned off wifi, 3g and autosync over the night, the battery percentage fell just as quickly.
Now, I've tried resetting the phone several times, as I thought it was an installed app that caused the drainage, but that wasn't the case. So, what else can I do when a reset doesn't do it?
Using a GT-i9000 with JPM/JP6 non-rooted.

Well, for what it's worth I too experienced exceptionally high battery usage when I updated to JP6 via KIES hack (same version as yours). Downgraded to the latest stock ROM for my region (Eclair JG4) and the issue is gone.
Now I think I will wait for the official 2.2 update for my region (although, having had a peek at what Froyo has to offer I think I can pretty safely even skip it without missing much).

I too notice a lot of power drain and general lack of ram. What I found was that froyo has a crapload of startup services/processes compared to eclair. I disabled most of them that could be removed and replaced most of the rest like k9 for email and handscent for messeging. System seems less laggy due to more free ram and more power as CPU isn't bogged down by extra unwanted processes like samsungs remote wipe and stupid sns

I'm also suffering from battery drainage with Froyo (JP6). I was quite satisfied with battery use on Eclair. Froyo has reduced battery life almost by 50 percent. I have same programs and I'm using exactly the same settings than with Eclair. I haven't noticed anything odd from the battery history statistics though. Only strange thing is that phone reports that screen in consuming over 90 percent of the battery all the time. Well, that's just not true.

it's a sensor issue, looking at the spare parts batt usage stats. but no idea what sensor/app is the culprit. very annoying

An App I use daily for all manor including checking battery usage is 'SystemPanel'. It's been a God-send and sorted out many a problem.
There's a Free & paid version but the App is that good I immediately went for the paid App.

In 6 hours battery has gone from full charge to 85% in standby mode.
Is this normal? Charge goes awfuly quick when using the phone.
3G on, all syncs off.
Running on Froyo reg hack. Same problem on Eclair!

Phone is 85% charge from full charge on idle over 6 hours.
3G is on, 2 bars showing. WiFi on, not connected.
Display 50%, WiFi 30%, Cell 14%, Phone 6%
Froyo, Eclair same usage except Wifi connected better with Eclair on home network...
2 meters from wifi transmitter and signal fluctuates.
Also, anyone's stock browser lags with yogurt? Was good on eclair
Is it because of fash? Seems to lag on all sites now.

Just to add to this... I had similar battery life in Froyo... HOWEVER, yesterday I used the Gallery and my battery drained from full in under 10 hours with no use (overnight standby with data off).
I check my battery stats when i switched my phone back on and they're okay for the 'since last unplugged'... however... for 'all time' gallery is also my highest user!
So, looks like gallery is only a problem if you use it... if not, it's fine.
crabby

I also have like a 2hr sensor usage on my gallery...
About the light sensor atleast on the JPM/JP6 theres like 2 steps of brightness full and low.. is this normal ?

+1 for that app! Paid one with possibility to see history over time..

Sensor usage for me was also 100% in spare parts, even if the phone was off. I had to turn off auto-rotate, and it quickly became a lot less. Although I have to say it haven't solved my problem! My battery consumption with full brightness over wifi is 10%/30 min. That's just ridiculous. I'm still on the problem, and will update anything I find out. We could actually make a "BIG BATTERY DRAINAGE" thread, where everybody posts detailed logs about the drain.

I have the payed version, How do I set it to monitor battery usage and show w/c app is using the battery so much ?

i'm on jp6 and my gallery is eating up my sensor usage too ):
looks like I've got to restart everytime I use the gallery.

activate monitoring under "menu / settings tab"
then you can see look under menu/monitor and select history tab..
on top tab where it says plot you can select top apps.
/H

just a question. you guys that are experiencing the sensor issues, are you on jp6? could it be a jp6 issue?

Exchange email accounts are a huge drain to in Scandinavian Froyo
If you set up Exchange email accounts, setting the Email retrieval update interval to anything else than 'Never' results in a continious 10% CPU load, draining the battery two times faster than in Eclair 2.1
Set it to 'Never', or have Tasker kill the Email app x seconds after Display Off
Determined by using System Panel app.

I have notice a large battery drain overnight with the OFFICIAL samsung froyo JPO. I suspect it may be the gallery/sensor issue.
1 can anyone affirm this.
2 can we replace the gallery or fix it
tanks

JPA was better for me. With JPO I noticed that the media scanner would eat up the CPU all the time. It seems to get stuck on certain files more easily.

My experience with GREAT Galaxy S battery life!

Hello Everyone!
I made this thread hoping I can shed some light to those getting very poor battery life. I was also getting very poor battery life, till I went and exchanged my phone for a new one. If you're getting very poor battery life (even after wiping your phone or installing a clean firmware), there is definitely something wrong with your phone or your battery.
I own a i9000m bought from Wireless Wave. I've unlocked the phone and am now using it on Rogers.
My previous phone, I was draining 25% of my battery to just get through 6 hours of standby while I slept. I had juice defender on and autokiller memory optimizer. I turned off all syncing and didn't even use a live wallpaper. My phone was rooted and also had lagfix (which I soon removed). One thing I do remember doing is not charging to 100% when I first got the phone. I did accidentally let it drain to 0% cause I had to use it right away.
After exchanging for a new phone and charging it to 100% right away, I was getting the following results. I have juice defender and nothing else. I changed my band to be WCDMA only. I even have a live wallpaper on. Last night my phone idled for 9 hours and it only drained 2%! Last night going out, I had a moderate to heavy (fbook, 3g, gps, text, youtube) usage pattern on my phone and it only drained 40% after 6 hours of use.
I don't know what else to say, but I'm letting those with battery problems know that the SGS is capable of great battery life. And if all your optimizing and tweaks aren't doing it, then you may want to consider exchanging for a new phone if you still have warranty.

I have a great battery life too in my device compared too the another smartphone i used in the past and now compared to Ip4 and N8 in this devices the bat drain is much higher. So im positive surprised with
the galaxy battery performance, i only use the push email everything else is turned off, livewallpaper and so on..

My phone came with JM7 firmware. My battery life is just excellent, not needing a recharge before a few days with my use

Running JPM here, with darkyy's raw metal ROM, my battery life went up by at least 40% - %50. I was losing 1% per 5 - 10minutes of usage, now its more upwards of half an hour of usage.

I think the phone has very good battery life if you understand what can cause battery drain and adjust it accordingly.
I am now gettining 5% drain per 24 hours on (almost) standby. This would give me about 20 days of standby which is crazy.
Here is my setup:
UK 16 Gb Galaxy S with Eclair JM6 and Voodoo lagfix
Set network to GSM (2g)
Disable internet usage (with APNDroid)
Disable WIFI, Sync Off, GPS Off (with power widgets)
Just before I go to bed, I run Advanced Task Killer and kill anything that doesn't need to be on memory (inlcuding Advanced Task Killer itself).
Using your phone WILL spend a lot of battery. Browsing the internet on 3g is a battery killer. This means that if you do something on your phone that maintains an active 3g connection, it WILL drain your battery in about 3-6 depending on your 3g coverage.
WIFI is better, but again you are looking at something between 6-12 hours of continuous usage, so make sure you only use it when you need it.
Finally, if you need to have your emails the instance they arrive, go for a blackberry because it has the only way of pushing email without maintaining a constant data connection.
I don't need this so I am extremely happy with my phone and the battery life I can get out of it.
I hope this helps.

Have my phone set for 2G with wifi always on.
Use wifi at home.
2G is enough for all normal syncs, and if I need more speed for anything else I temporarily switch to 3G for that.
This way a single charge last me well over 24h under normal usage. Don't even know exactly how much.
With the phone set to 3G, the same usage patern will eat a full charge in something like 8h.

JPM Rom with everything except bluetooth turned on my battery lasted 3 days with low usage (skype a few times and some phone calls and a bit of wifi web-browsing.)
Much better than my wife's iPhone 4... Normally charge it every 2 days.
I am very happy with the phone, just a couple of bug fixes and I would really like it if Swype did some level of contextual checking of words to help minimise unnecessary corrections (perhaps they do already, but it is certainly not well implemented/sophisticated enough).

Which ROM was on your old SGS and which one is on the replacement?

Eclair for both. No Froyo.

what i wish to have is greater control over the phone, more easily.
Some kind of powertop GUI that let you see the power usage per process.
So you could plain uninstall apps installing ****ty services consuming the battery.
Likewise i'd like *real* control over which background services are running. I mean running an auto killer wtf? Horrible design!
I just want to switch off a service and that it doesnt start again 5 min later thank you very much.
Even the task manager is quite bad. You see last started apps but you don't know which one is running right now. And if its running and backgrounded since a while and you started other apps.. it might very well not even show up in the list anymore. Horrible design again.
Saying all that because stock the phone battery is excellent, installing a couple of popular apps kills it..

Thanks for your prompt reply. Could you check it more precisely on your current SGS? FYI: Settings -> About phone -> Baseband version and Build number or "call" *#1234# -> PDA, PHONE, CSC version numbers. Thanks in advance.

Sure thing. And thanks. KIES offered an update from JM1 baseband and JM2 build version. We'll see how the new ROM performs in about 3 days. Unfortunately don't have spare time to do that sooner. I suspect there's huge difference within the baseband versions.

hey guys.
i have galaxy s i9000..i also had problem of battery.my battery would hardly last 24hrs...i even switched to gsm only mode n switched off sync.but still had same prob..few days back i installed JPJPA firmware..now its wroking fine.lasts more than 35hrs...n also battery charges quickly

Is it possible that the reading on the phone is wrong? When you say you are getting 24 hours are you letting it run flat.
Alternately is it saying the battery is running low and you recharge before it goes flat?
Just wondering if the meter is simply giving incorrect information.

Been 24 hours since last recharge. Lost 6% so far. Running JP6 Froyo. Rooted. Network Data Off. During this 24 hours, just used Angry birds-30mins and ColorDict 5mins. Haven't installed any unnecessary app.
Had lost 1% on standby after 14hrs with no usage. Thats amazing. Very Happy user.

Also want to tell u guys that GPS with active Data connection and Google Maps running and display on took approx 1% of battery every 3mins.

Impossible using stock battery, this phone draws a minimum of 10% battery per hour the screen is on. Its more likely 15-20% with most peoples phone.
Your battery meter may be inaccurate, for example after flashing once my battery stayed at 100% for hours then suddenly shot down to 20%

I use "Battery Indicator" to check my battery status.
My screen is set to turn off and lock after 30 seconds of idling. So it is quite possible to achieve the standby times listed.

Hi, how long do you have holding time of battery, when you are using wi-fi? (browsing)
