Is a lower lifetime characteristic of a WM6 ROM? Before flashing I used to be able to get ~two days life on WM2003, now I struggle to get 12 hours.
I do have the Soft GPRS tweak installed.
I've seen other posts relating to power off at around 30%, but this isn't a problem for me - I'm still getting life at 12%. It's just that I get to this low level so quickly, and have to charge each evening to have power in the morning. My battery is original, and otherwise the ROM (helmi_c's) is stable.
Any hints or comments?

mine is significantly shorter than when i was in WM5. but not as bad as yours. try this. go back to WM5 and see if it still gives u 2days.. then go back to wm6. then if u still get 12hours max with the same usage as you have with wm5.. then it's the ROM.
if you get poor batt life even going back to wm5, then maybe it's the battery. consider borrowing a battery, or buying a new one..
Are you sure your battery can stand only 12 hours ? it's too short. Try to reduce thre brightnes to save the power of your battery.
Ta for the suggestions.
I already have my screen brightness adjusted, and auto power off as appropriate.
Battery is the original, but behaved with 2003. I have two Himalyas (bought the second off a colleague for £40 as nervous about playing with ROMs!) and so two original batteries; both behave the same. I also inherited an aftermarket battery which is truly awful - goes haywire after down to ~45%.
I did try WM5 for a while, and don't recall the battery problem. As I have two devices, switching one to WM5 and comparing is a good suggestion. Unfortunately I need one application (NotifyLink - see thread in the WM5 forum) that I've not been able to get working in WM5, and *does* work on WM6, so if I need to go back it's WM2003SE for me :-(
Before trying to flash back to an older rom, consider some other battery saving options.
Lowering your screen brightness was a good idea, which you have already done.
Some other things to consider:
Turn off "Receive All Incoming Beams" until you actual need to receive something via bluetooth/IR.
Turn off bluetooth if you are not using it (this used to be a massive drain on my himalaya)
After closing a program, go to the task manager and make sure it is actually closed. THe cross in the top right hand corner usually just shrinks things. You can buy/download applications I believe that will actually properly close a program. I've on occasion had 8 progrms running at the same time simutaneously before closing them.
Make sure the terminals on your battery and himalaya are clean (where the battery connects) and also test to make sure your battery is seated correctly.
Change the timeout for your device (IE how long it will wait before turning its backlight off, and then turning off in full). Mine is set to 1 minute. You can set it as low as 30 seconds but I didn't like this as I felt it would wear out the backlight.
If I think of more I'll come back and write them. Perhaps someone has already made a "Save battery power" post. If not, perhaps someone will make one and the mods can sticky it.
cheers
The battery is geting life expired. Better buy a new battery..
Thanks for all the replies and suggestions.
If I've besmirched either of the ROMs published on this forum then please except my apologies - I discovered that my battery problems are NOT due to the ROM. But nor are they due to my battery!
Re-Flashing (or hard reset with reboot options) gives me good/normal battery usage. I therefore figured that my problems _must_ be due to an installed application. It didn't take me long to determine that this was due to NotifyLink, which I unfortunately need to install in order to receive my corporate email. With this present I lose approx. 6% battery power every hour(!), even with GPRS disconnected and the application not checking with its server. Just installing (even before configuring) the application I get this immense battery drain. Weird. Removing my SIM card doesn't help. Neither does uninstalling; I need to hard reset before battery consumption returns to being acceptable.
As I need this application it looks like I need to accept the need to top-up every evening.
(Medium term I know my company are moving away from this app, but will require DirectPush - anyone know if we can activate this in a Himalaya ROM?)
i recently replaced my battery for a new one. it was near 3 yrs old and it's battery life was steadily decreasing lately, shutting off just about 6 hours after a full charge! when i bought a new one it shuts of at 5% on the same rom and operating conditions, nice huh!?. so as a rule of hand slash of around 15-25% of battery life for every year of use. better yet save up for a new one while your on it .

Good job. As you can see on notifylink's newsletter they're very specific on devices fit for the job, for example not just any Wing, but TMobile Wing...

As far as I know all you need for direct push is correct settings of exchange server and a device with WM5 or WM6 with built in MSFP or WM2003 with Global Contact Access installed. MSFP should probably be in your WM6 ROM unless your cook cut it out. In that case you can either try to find it in the ROM kitches of recent HTC devices and see what happens if you cook it into Hima ROM yourself. I don't know which file(s) you should use. Or you can download GCA and see if it works on your WM6 Hima.
Maggy - Many thanks for the response. Yes NotifyLink do recommend specific devices, but I've no idea if their battery consumption is any better. I do see from various postings here in my company that I'm not alone with problems - generally advice is to just check with the server less frequently, etc, which doesn't solve my issue. I'm going to have to live with this inefficiency for the moment.
As regards DP, I'll await with interest my company's progress in moving to this technology. Thanks for your information!
I have similar problem since WM6 Tofclock ROM is installed - getting just about 24hours battery life....Although the battery is quite old the Rom has definetly some incidence on this --- I have installed batti 2.1 following some threads i found here, hope it will help
Actually, I found out the same strange thing, while I was trying to solve another problem. I changed almost all of the OS/Radio Roms combinations, and with WM2003 the battery time when the phone is in stand-by is significally greater than with the WM2005 or 2006 Rom (days vs hours)... and this happens with every radio rom.
Right then,
I am a n00b here, and am expecting a bunch of 'search for it' responses that seem common in my reading of the forum over the past day or so. I have tried all of the tweaks recommended and still suffer from poor battery life. Today for example, day 4 of having the phone, and having been charged approximately 6 times during that time, the phone has only 2 green 'bars' of power left after only 8 hours of being on. During that time I have made no phone calls, and sent/received about 8 sms messages.
Anyone have any ideas or similar problems? I understand that this phone suffers from limited battery power, but mine seems particularly bad.
Thanks anyone who can help.
could be a bad battery?
I improved mine by disabling the GPRS auto-attach (massive saving) and truning off wifi using comm manager when not using it but by the sound of it you have tried these...
Mine lasts a few days now.
I also got good results from Bepe's and TDP's ROMs but it's probably nad to flash if you are thinking of sending it back as faulty...
Yes, also as a 'n00b' I'm not too confident flashing it just yet. The battery does get hot during charging, something others say doesn't happen. I think it may be a faulty battery. I have turned off the auto-attach and also wifi, as well as any other tweaks that were mentioned on here regarding battery life. Nothing seems to be working. Anyone else have any input? Thanks.
Same problem here.
I also flashed it with TLR ROM... but the problem is the same and very annoying.
I use it in a very normal way without any strange usages.
For me the battery resists only 75% of the day... and it is terrible!!!
I tried also with the minumum of brightness.... but you can't use it like this all the time!!!
Any suggestions??
Thnx!!
I am thinking of phoning Orange (who I got the phone from) and asking for their help. I think I might have to send the phone back which I really don't want to do. I hope they might just ship me a replacement battery.
wow. u get 4 hours? mines more like 2 hours. im on my 2nd diamond with the same results. i tried all the different roms also. u are not alone. my fix was going back to using my old touch.
You should flash a new rom..I recommend you shep's new rom and get radio 1.12.25.19 with matched rilphone2.dll..your diamond will stop suffering from battery draining.

Just in case you haven't tried all tweaks and tips yet, have a look at this Battery Conservation Fanatic thread.
If the battery is OK, you should try with a new rom. I had the same problem: my Diamond were with Vodafone default ROM and the battery lasted half a day... now with a cooked ROM, the battery lasts near two days.
Good luck!
900 mAh is btw way too small for such a phone, I recommend you to get a new rom/new battery. I'm waiting soooo much on my new 1800 mAh battery........
I’ve get a HTC diamond from a friend and am having problems with the battery. I’m trying to figure out the best thing to do.
Generally I’ve found the battery is a bit low in capacity (as others have mentioned on the forum). But more recently I’ve found that the phone will suddenly die, without an battery warnings. The battery suddenly seems to be fully discharged.
I’m wondering if this is a problem with the battery (or more worringly) with the phone. Is there any battery monitoring software that might be informative? Or should I just buy a new battery and keep my fingers crossed?

You could try this for testing the battery:
http://www.spbsoftwarehouse.com/products/benchmark/
You may need to check it against someone elses benchmark to get an idea of a problem or not. I think the battery test is a long one though as it has to run it down completely after a full charge.
You could try disabling any programs that automatically connect to the internet (eg. email) and I think there is a cab somewhere that will disconnect gprs/3g/hsdpa when there is no activity. If I find it I'll post it here.
I found that the Auto Adjust Backlight used up more battery than needed so just set it to the second marker on left (start > settings > system > power > backlight). I'm sure there are many more options to save battery power that are mentioned in other posts but I guess you have already been through them.
I found that a full discharge then a full charge while the phone is switched off completely (not in standby) helped a bit but not much.
There has also been some problems with peoples battery monitor not being accurate. Like it saying there is 25% battery when there is really 75% of power left. But this problem has been few and far between.
You can also go into your settings/notifications and set a notification to let you know when your battery is about to peter out on you.
Hi,
i've searched the web, searched here in the forums for a good guide on how to calibrate your battery, but i found many guides for many phones, so i just looking to find the right way of doing it for my phone.
i own a Samsung Galaxy S GT-I9000 i have MCG v6 MIUI ROM with NEO 06 Kernel with it.
i also have a 3500 mAh battery with my phone.
every time i flash a new rom i wipe the battery stats, i tend to charge my phone everytime i get a chance, trying to keep it as high as possible. i also tend to let my battery run out, then charge it all the way up once a month.
i also notice how every time i shut down my device or take out the battery i lose about 5%~.
so if anyone can guide me the right way of calibrating my battery it will be great and much appreciated. thanks.

I do have same phone with 3000mah battery, I amusing the phone for aabout an year, installed various updates, custom ROMs, nightlies...etc..
I never done a battery caliberation.
Every time when you get a chance, charging your phone is wrong, it will kill your battery soon.
Read this carefully
http://www.androidpolice.com/2010/1...bump-charging-and-inconsistent-battery-drain/
it is quite normal to see a 5% power loss after reboot, but it is an incorrect reading.
After flashing a new ROM or updating, best option is do not plug into a charger. Allow your phone on standby and turn off some unwanted features, if not in use like, GPS, background sync etc.... Ideally you should turn them off before updating, allowing your modem to start with minimal load, so it can rewrite dalvik cache with minimum error.
Within few hours after updating, batterystats will get back to normal. I atleast give 6 hrs before I plug into charger.
Thanks
Hi,
I don't have sufficient posts to be able to participate directly in that forum, so have no other choice but to raise my queries here.
I've just flashed over from Overcome "Hermes" to "Jupiter". All's well except that the battery performance is quite drastically affected for me.
I've been reading the improved battery life "Jupiter" gets over earlier versions of the Overcome ROMs, but I seem to be experiencing the opposite.
Already did the batt stat wipe via recovery menu. Do I need to so call "run-in" before it reflects correctly? Even if accuracy is one thing... but dropping 3% just on bootup.... is this typical of an uncalibrated battery?
Appreciate any advise here on what I should do. (Apart from a fresh wipe install )
Thanks
I appreciate the enthusiasm these coding geniuses have in rolling out update after updates in the ROMS yet I am apprehensive about the effect of these frequent flashing on the Galaxy Tab components itself. This includes the battery.
My job involves electronic repair and there is a so called number of hours before an equipment goes for a thorough check(preventive maintenance) say for example 1000 hours on a meter. Unfortunately the galaxy tab (or any tablet) does not have this. So if you frequently do a flashing on your tab you subject the electronic components to unnecessary stress,thereby affecting the life of the components like the battery.
In "normal" everyday use of the tab you will seldom do any restart/reboot of your tab,yet in flashing ROMs as many as 3 reboots is needed. As I don't know how to measure the surge in current during reboot, I can just imagine how high an initial current during startup is generated, thus putting a big strain on the battery.
Unfortunately the battery is not user detachable.
There was an author here in XDA describing himself/herself as an "flashing addict"(or something similar). I would like to appeal to everyone-please don't be a flashing addict.

According to the Tweaks section at the team overcome website, it will take several charge cycles before you notice an improvement after the stat wipe. Try giving it a few days before going any further.
PS Not to question your ability to follow instructions (sometimes we miss things) but did you charge to 100% with the tab off?
Yes, I did charge to 100% with the Tab off.
Now upon reading the instructions once more..... I might have conducted it slightly different from the written procedure.
I unplugged the Tab from the mains, then only booted up and wiped the batt stats before re-booting. Hmmm.... maybe I'll go try booting up while still plugged into the mains, do the batt stat wipe, and re-boot. (all while plugged into the mains). Then only unplug the charger.
Wonder is there any diff in doing so.....
Would definitely try re-doing it with the tab plugged in while doing the stat wipe. And if it doesn't seem to fix it, do go through a few cycles before reverting back to a previous ROM.
It's important to completely drain your battery before recharging it to 100% in order to complete a cycle.
Hope you fix it. Battery life results vary between tab's even if they are used very similarly, I'm running the OVERCOME Jupiter ROM with IMPROVED battery life. I keep my Bluetooth, Wifi and GPS on all the time. I also flash quite often and have not seen a decrease in overall battery life. It seams that each tab is a bit different, hardware wise, than one another. Everything from battery to board it seems is slightly different coming out of the manufacturing process.
Thanks. Will try that out.
But it just seems strange coming from Overcome ver 1.4 (Froyo) which had no batt drain problem.... to Hermes which was better in batt performance.... to Jupiter which I'm experiencing heavy drain.
As I did a NoWipe install, all apps and setting are similar (except the new market app).
I was able to run 2 movies back to back (about 3 hours total) and still have at least 40% life left (usually about 45 to 50%). Now on Jupiter, just fiddling around testing the various features for functionality, plus maybe an hour of NFS (total about 3 hours as well).... the batt drops to about 10% life.
Anyway, I'll re-do the calibration and and give it some time to "settle in". Hopefully, that is all that is needed. (I would hate to have to do a full wipe install... and re-installing all apps)

As mentioned in the Tweaks section, perform the Stat wipe and then two full recharge cycle
recharge to 100% (while the Tab is closed) then drain the battery till it is off then repeat the cycle and you will enjoy it man
Please tell me if you need anything

Viewed purely from an engineering perspective, I'm unable to see any significant connection between the flashing of the ROM and a degradation of battery capacity. Further, in the event that the TAB was connected to a charger during the flashing, I can see absolutely no connection at all! Please help me understand your logic.
Ok Back on topic. PCdumb (dude what's with the username lol). Check your app list. It could a new app you or an old app you updated or an app you didnt use before but you use now that is being a battery hog. A small trick I learned is checking apps running services in the background. Go to Settings, applications, running services and check (why is skype working after Isigned out its not a battery drainer but I hope you got the picture).
Thanks for the advise. That was one of the 1st few things I did to check that there's nothing out of the ordinary running in the background and taking up the juice.
Mine's actually draining alot when in usage. Not too sure about when in standby.... will check later.
If after a few charge cycles and the drain is still bad, guess my only next best option is to do a full wipe, re-stock and re-install.....
I did not get any effect from Battery calibration. As expeced. Anybody did actually?
The background services instead might have an effect on power consumption, I agree. But needs numerous testing...
Batt recal did not give me better battery life. There's no difference in the battery performance after 3 recharge cycles.
My tab can at most get slightly more than 5 hours of continuous usage compared to about close to 7 hours on hermes. This is when i dial down the OC from smartass mode to conservative and also put the min freq to 200 instead of 400 which was the setting i was using all the while.
Doesn't seem to be anything else running in the background. On standby overnight, i only lose about 3% which is not too bad. But when in use, that's where the Batt drains fast. Just for comparison, i only lost 1% at most for overnight standby of about 7 hours when running hermes.
Guess I'll have to live with this if i want the speed and smoothness. Still contemplating whether to restock and do a clean flash.

If you want to confirm that JUPITER is the reason that you are experiencing poor battery life, try re-installing a previous version that you feel worked better for you. Maybe reverting back to a previous version may yield better battery results, and I sure hope so, this way you will know if it's the ROM or other elements affecting the abnormal battery drain.
If you do see an increase in battery life, try flashing JUPITER again, see what the results are. I don't know if flashing and re-flashing will have a negative long term effect on your SGT, I know that I flash every time a new release is out (Stock safe, cooked ROM, Kernel) and if i'm not happy with the release i go back to a proven one by flashing another three times (stock safe, cooked ROM, Kernel) and so far I have not had any (knock on wood) abnormal battery activity.
It's worth giving it a shot (if you haven't already).
EDIT: I know, I know the proper sequence is stock safe, kernel, rom.
after week of using the Overcome ROM i can confirm that the battery performance is between 85 and 90% from the Orignial stock ROM performance
No problem since this is normal as we are using a cooked ROM

I do get 4 to 5 hours of continuous use with overcome Jupiter, mostly browsing the web over
WLAN or umts. Hermes release didn't gave me so much more juice, probably 5 hours.
In the background I have emai push, contacts and calendar sync and some instant messaging apps, if I switch off all that I might get an hour or so more.

Wow, maybe your tab is one of the ones with a battery from the bad batch, and it's finally on its way out. I upgraded from the stock AT&T Rom to Overcome Jupiter, and on Airplane Mode with all stock settings (no overclock or undervolt), mine only drops 1% in standby over 14 hours and I can get about 5 hours of video watching straight with the brightness on max before it dies!

I also been experiencing a major increase in battery drain even after doing a couple wipes exactly according to the tweak guide. I went from about 24 hour normal use down to 6-8 hours normal use.
Checked the services as per your suggestion above and found a couple major battery drainers running. Skype and Yahoo but also Google+. What I dont understand is why Skype and Yahoo would be running even though I had not started either since at least several re-boots ago. I had Skype and Yahoo installed for quite a while Google+ is a new one. Anyway I killed all of them and now and will see what happens next.
Not sure thought that this is all there is to the issue. Recahrging is finiky as well. I can turn off the tab and let it charge all night just to find that it charged to about 70% if I re-plug it might charge to 90%-95% and then if re-plug it might get to 100%. The drain from 100% to 60%-70% is extremely fast and still quite fast from there. On one occasion after complete drain I couldnt get it to start charging at all for about 5-10 minutes. I was checking power, cables, connections and starting to panic when all of a sudden it started to charge.
Any advice on possible reasons or solution woud be appreciated. Not sure I want to go beck to stock ROM and un-root just to take it to service center for repairs.
