Hi, my batter has been working great since Christmas, but now for some reason won't last more than a fwe hours without saying battery low. I have my gprs check email every 5 minutes, but it has always been that way and I have been gettnig a good 2 days out of my phone before.
Now i take it off of the charger in the morning and then around lunch the batter is low already...
Is my batter just toast?
Should I get another?
THANKS!

Just a question, but have you been overclocking your TI OMAP processor? Maybe there's a correlation?

Mine is brand new (tmobile MDA) and when I enabled 802.11g I noticed a dramatic drop in battery life. I think for the sake of the battery I will only enable that as needed.
I wonder also if you are in the same proximity to the mobile towers, if you are on a border between coverage you will see a drop in battery life becuase it is transmitting more frequently to register with the mobile network.
To try to see if its your battery or something you are using, and while this may be incredibly difficult with a mobile, especially a mobile/pda that you use frequently, you may want to see about turning off features to see if that helps. Turn off wifi and see if that helps, turn off bluetooth and see about that, etc. Once you rule them out as the major culprit ...
While I highly doubt this may be the case, it is a possiblity, and worth looking into, especially if you noticed a sudden drop in battery life as opposed to a gradual diminishment. You may have some rogue software that is sending out more data via a wireless device than you desire. A worm, trojan, whatever. There are anti-virus packages available, I dont know how good any of them are, http://www.freecabs.de has some, some of the big commercial guys make some. Again I dont think its that becuase of the rules of probability, however it is possible and some have been known to exist in the wild for a few years now.
T,
I had the same thing with my c500, now I know they are two entirely different phones but after I flashed the device it was as good as new in terms of battery life.
It may be worth a try before you go and buy a new battery.

I have the same problem.
Not overclocking, no anti-virus, just regular phone use and my battery does not last a day!!
I keep it on charger most of the day to avoid shut-down.
me too
I've the same problem and I've an other big problem, when I turn off my Vario, it's dont't start on power botton (i must extract and insert a battery turn on the telephone).
We can make a test if anyone have a HTC diagnostic software (see service manual.pdf)
Check your today screen.
I too had the same issue. Mainly, PhoneDashboard was causing the battery drop. Along with any today elements that poll your hardware to display the amount of battery, memory and storage. Those all drain your battery.
To check whether it's really a today screen issue or not. Charge your battery to it's full 100%, remove ALL today screen elements, then use your mobile normally and keep checking the battery level drain rate.
Hope this was useful.
Mine dies, 100% when leave work, some usage and then dead in the morning.
I only have Pocketbreeze and a few plug ins installed.
There is NO wireless /bluetooth in that time.

nope.
I have not been using wifi at all lately either
I have spb today stuff but have had them since I first got my wizard. really, I have not changed anything....
some programs "eat up" battery life. Investigate by doing a HARD reset, then do not install ANY software for two days. I bet you will see your normal battery life ;-)
I took all today programs off
100% at 5.30
32% at 7.30
This is O2 Mini Rom without all the 02 crap.
I will investigate further. Hard reset here we come!!
Last night my battery was 100% at 5.30 after a hard reset, no o2 software installed and very light usage.
This morning at 7.35 it was 50% which is good I guess???
Suggestions as to whether it is the battery?

Still not good enough, should hold for 3 days if you do not use it. Get a battery replacement.
Typically I charge every other day, little phone talks however.
PhoneDashboard was causing the battery drop

Ah, I run this. Is it bad? I've turned off all the scrolling updates etc - did you find that helped?
Got a battery replacement but still after no real use dropped to 50% in only 13 hours.
Any other ideas?
mine works for about 5 days normal usage with this options:
- phone on
- bt off
- wifi off
- automatically receive IrDa incoming... (Connections ->beam...)
so the wifi on my batt only last for a few hours, but when you disable wifi and the irda incoming you should have more batt. life
Thanks I will give this a try and have taken out irDA.
However my figures were with Bluetooth and Wireless off as well
I have noticed that with wifi on (and particularly if I'm using it) the battery drops at a frightening rate. Whereas with wifi disabled (which it's been for most of today - first day since I've had the XDA that I've been busy working and so haven't been 'fiddling' with it at all ) the battery still seems to be sitting happily at 80% after around 8 hours.
Funny, I thought that if the phone was suspended, the wifi would be inactive, so the battery wouldn't drop. Appears that's not the case...
Do u have Spb Pocket Plus installed? this program sucked my battery flat in 1 day. I removed it and now its up 2 or 4 days depending on how long i have wifi on. Checking email every 5 min also reduces battery life allot.
goodluck
No pocket plus... My today screen just has phmtray, resco today, taskplus, and the pocketmusic plugin...
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.
hye,
I just bought a HTC leo which I really love.
but there is just one thing I'm concerned about, the battery life.
with my htc touch pro 2 I was able to use my phone 2 days before recharging but I can't do that with the htc HD2
IS THERE A WAY TO IMPROVE BATTERIE LIFE?
thanx
use less of your phone the hd2 drains the battery and is very good at that.
Or you buy another spare battery to switch with the exausted one when you're on the go, they're pretty cheap on ebay with a mains charger
only tips, would be turn all you're updates off, i.e, email, weather, twitter, stocks etc. screen brightness, not much else really, i get a full day out of my battery with everything turned on and full screen brightness so im happy
switch off 3G whenever there is no need for it, best is using a tool like wmlonglive to do this automatically. Will improve the battery live especially if signal strength is changing often between 2G and 3G
don't use windows live push mail, it will improve your battery dramatically
edward
my HD2 just takes 30 minutes to drop from 100% to 70 % .....
from the bottom of my heart , i want to say , htc fone ..... not good as they say ,
crap
battery drinker
just after some games , it hots ...............
will change other fone ,
I do not have a problem with the phone. it lasts me 2-3 days depending on where i am. thus depending on phone signal strength.
Further when you want to improve battery life look at the treads about that. there are so many with so many suggestions. quite a few have improved my battery dramatically. search and try.
@Felix
Are you using a Stock-ROM?
When yes, then install atleast BsB-Tweaks and activate the powersaving settings ... (the most cooked roms already have this settings)
It will bring some extra minutes/hours
My HD2 (fully loaded over night) is at 77% after 8 hours and some phone calls (ca. 30 minutes), sms and some gaming and surfing
@enchanter
yes, it drains the battery pretty good and yes its becoming hot when you play games or stuff ... but what is the problem with it?
We all knew this - before we bought a HD2
ha ha , Pliskinius has the coolest answer
" what is the problem with it?
We all knew this - before we bought a HD2 "
u right man ,
@ pliskinius: I don't know what a stock rom is... it is the rom who was installed when I bought it.
my battery lasts one day and a bit, so there is not really a big problem, but when you go somewhere and forget your charger...
@enchanter: I'm really pleased with my htc, its my 6 or so and they become nicer and nicer..

Try this fully drain the battery until the phone shuts down then take out the battery for two minutes,put the battery back in (DO NOT TURN ON THE PHONE) and charge until the green light comes on, take out the battery for another two minutes then put it back in and start up, this should improve battery life.
Also other factors affecting battery life are the Rom version,Radio and HSPL.
nice idea @nosh - will try it too ... maybe it brings some extra minutes
@Felix
you are using a stockrom (stockroms are the original ones, wich are installed when you pick up a new phone)
get this little tool http://forum.xda-developers.com/showthread.php?t=589305 and activate the energysaving feature (will improve the battery life)
@ nosh 10: I'll try that thanks, but I heard that fully draining your battery is not a good thing.
@ pliskinius: haha, yeah I know I don't know a lot about WM
Laurentius26 ROMs get an excellent battery life. I get 2 days without deactivating anything. And everything works perfectly and smoothly. I have the 2.10.50.26 radio ROM and the Laurentius26 GoldEdition V2.0 Spike™ WWE 21899. Can last up to 2.5 to 3 days by deactivating 3G. I download weather every 3 hours, tweets every 4 hours, e-mail every hour. Then I make phone calls about 15 minutes per day, sms 10 to 20, pictures about 10, surf with Opera about 30 minutes per day. Remember also to close all unused applications (for me the best task manager is the Touch X manager that is on Xperia X2, lets you choose between short click on the cross to minimize the app and long click on the cross to close the app).
Edit : It's now 15:50. Was 100 % yesterday evening by 22:00. Now it's 73 % left. But I only used my phone since that time to make a countdown for cooking at lunch time.
I'm currently in Japan, using phone on 3G, very little use, listen to some music daily (30 min) and play around an hour. I'm getting 3 days easily without a charge and could easiy stretch to 4 days.
Back in my country I disable 3G and use only 2g with auto updates on every 3 hours, no email push no twitter whatsoever, just weather updates. During the night the battery drains down by 15% and with normal usage I'd have to charge daily.
15% during the night with maybe 2 updates during the night and data connection disabling just after a few minutes shouldn't drain the battery by that much. Dunno, but I'm pointing my fingers towards 2g.
I'm no expert, actually I'm far from that, but could it be that 2g uses more power from the phone?
Without any usage at all, here in Japan, I hardly get a 10% battery drain in 24hrs compared to 15% during the night back in my country.
Maybe new comm chips Edge eats more than 3G as all the phones are now optimized for 3G, I wouldn't be surprised at all.
But one thing is sure : if you have bad 3G coverage or bad quality signal, it really drains your battery. Only way to avoid this : disable 3G and you phone will stop changing from Edge to 3G or HDPDA several times per minute.
I'm using WMLonglife, and I've set it to 3g only. Now I have no idea if here in Japan they have HSDPA or Edge or if the software is keeping the phone on 3g, but I haven't seen the phone changing from 3g even when the reception went down to 1 bar.
But i'm pretty impressed with the battery life at the moment. Pity i won't have the same battery life back home.
G'day everyone,
I'm wondering if anyone has experienced a similar issue to what I'm having on my x10i.
I use to unplug my device from the charger around 7am (100% - fully charged) and the battery dies around 7pm. The main usage of my device is for making a couple of short phone calls, sending/receiving tens of SMSs, regularly checking my facebook, twitter and email account. Not a heavy usage I think, around 85% of the time is put on standby. I was really unsatisfied because my other device "HTC hero" stays for over two days. A few facts about my HTC Hero: 1) It is way much older and nearly damaged, 2) I am using it mainly for family/personal really long calls (30-45mins per call) and 3) Always connected to my car's built in phone system (Bluetooth is up all the time).
Since I bought my device 2 months ago, I was in a continues contact with SE the Middle East regarding battery issues. Honestly, they were very informative and respond quicker than any other company I dealt with before. They replied to me with really useful tips that extended my batter life to stay alive till the mid night (extra 4-5 hrs). Tips given were: Brightness automatic adjustment, Disabling auto Wifi detection... etc. Though, I was still not quite satisfied.
One day I decided to do my own experiments to observe the real problem with my x10 battery. This was 3 days ago. The first thing I started with, and apparently the last, was disabling the 3G service. I turned off the 3G service, and turned on the 2G (Edge) instead. Believe it or not, the first day my device's battery status was about ~85% when I got back home from work, ~70% at the mid night, ~55 percent when I woke up the next day, ~25% when I got back home, and dies around 8pm (from 17hrs to 37hrs). It was a straight shock to me. I already know that enabling 3G would shorten the battery life for both the short and long term, but honestly I wasn't expecting this much of difference in the daily usage. The other thing, I didn't notice any huge difference between before and now. Internet surfing is a bit slower, couldn't notice the difference. Twitter, Facebook and email worked just the same since I check them whenever I got notified. The last thing is I'm using mobile messenger now, i.e. eBuddy, since the battery is giving me longer time, and all my messenger accounts are on all the time.
Please, if you are having the same issue, let me know because I was assuming that there's something wrong on my device, either on the battery itself or the build software (build # R2BA024)
Regards
The improvements you're seeing are probably due to you living in an area with poor 3G reception. The poorer the signal is, the harder the phone has to work to maintain the connection, thus, eating battery faster.
Although, it shouldn't be THAT big of a battery loss... I'd look at what programs you have installed and running and see if any of them are secretly eating battery behind your back.
You should try installing and running "Data on demand" It switches your data connection off when the phones screen is off...
Its well worth upgrading to 026, i saw a huge increase in battery life from that.

Absolutely correct. At home I can leave my X10 for days without it dying with 3G enabled. At work there are dead zones that'll suck a phone dry within an 8 hour shift though. It's almost always a coverage issue.
For any battery issue I suggest a factory reset and THEN make the appropriate adjustments. Sounds useless but sometimes you can emulate all the same settings and things still don't happen as anticipated.
Use a 3G toggle widget for long periods where you KNOW it won't be necessary. Root your X10 and add SetCPU to that bad boy. Screw using task killers because the Android OS is *nix based and handles memory just fine - I only kill tasks before putting my phone away when I know I won't use it for an hour or more. Other than that, don't use task killers, battery monitors or anything that'll keep your phone from sleeping. Use Spare Parts if you need help identifying an annoying program too.
Thanks all for the useful comments.
Now, I feel more confident that I can keep the battery alive for even more than 2 days. Thanks for your information and knowledge : )
[Q]: Is there any application that shows (in bars or digits) the strength of 3G signal?
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).

I was also getting very poor battery life, till I went and exchanged my phone for a new one.

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)
