Battery lifetime

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.

is this the correct way to recover from battery drain?

I recently upgraded my wizard from a wm6 rom to another and started to notice the battery indicator dropping much faster if I'm on EDGE networks (but maybe also with GPRS, I'm not sure). Since I didn't flash to the official rom before, I thought I had the common battery drain, so I did this: full backup using spb backup, remove hardspl, flash to original qtek rom, hard reset, flash updated radio rom, softspl, flash to wm6 rom, hard reset, restore previous full backup.
The problem is that I'm still noticing the battery going down faster than before. I'm not sure about it, because with this new rom I have a more reliable way to measure the battery, but before flashing all over again and reinstalling every single program (lots of time) I wanted to ask if my method of flashing does solve the battery drain problem (and therefore this is normal for this rom) or if this method does not solve the problem and I have to do everything without the full backup.

- check if processor speed is always high. Latest BatteryStatus allows variable speeds according to the needs of the OS - calls it CPU scaler;
- check if bluetooth or infra-red are turned ON as they drain some energy;
- check the backlight. Mine is always at the minimum and works fine in almost all occasions (except under bright sun light)
- disable Today timeout
- check power drain with a new battery (if you can get one)
that's all i can think of. maybe others can think of other reasons.
good luck

maybe I didn't explain all... I know what can cause greater battery usage, and I try to avoid it, but comparing the previous rom with the new one it seems the new one uses more battery. I also know this can be a "feature" of the new rom and I don't mind about it, because it's really much better. What I want to make sure is that the battery drain is not caused by improper flashing, because that's just wasting battery for nothing.

ah, right.
I don't think there's such a thing as 'improper flashing' when the new ROM works ok. Except for not performing a hard-reset afterwards i guess nothing can cause that kind of power draining, although some have mentioned corrupted extended-rom but i can't vouch for that

Currently I DO think there is something like 'improper flashing'.
I've read about it in another topic as well.
Since I upgraded to WM5SE rev4 I suffer from a severe battery drain.
For some time I suspected my dual sim adapter (did change to that one about the same time as upgrade), but even without adapter the drains stays wel above 100ma!
Until now i have eliminated all other possibilities.
The best way to upgrade to any custom rom appears to be:
- Flash to an official ROM
- Flash the custom ROM.
I seems to have something to do with the ExtROM that sometimes get 'a bit' corupted causing tha battery drain. Flashing an official ROM makes sure youre device is all fresh before getting the custom things on.

ok, but I already did that. The problem is that I'm still seeing some battery drain, especially if I'm on an EDGE network. I just wanted to know if restoring from a full backup using spbbackup after flashing properly could be the reason or if I must find another cause.

Sometimes can be a Today plugin that is performing some task all the time and that might cause battery drain.
there used to be old topics on that matter so i guess you must dig and raise some dust to get it clear

now that you mention it... there is a new plugin in this rom, I'll disable and test. But I still find strange that when I'm on gprs the battery drain is almost inexistent, but on edge is really big

Did you solve your problem?
I can't!

I have experience some issues
When I started trying PDA VIET Roms i feel like I got a new device cause it has superior speed but its caused by An app called OmapClock PLUS that enables an overclock, thats why the speed but it has too many batt drain... so i leave the PDA Viet Roms... I always first downgrade to an original ROM Wm5 then upgrade to a Custom and then hardreset... of course sometimes with a batt at 55% (enough to flash) but Mr SVI on his first release BrightRom has too much Batt monitor... it causes too a batt drain cause the reload constantly by itself to show batt drain... disable all. and no more problems jeje even on his Hornet v1.1 it has drain for me.
Somebody tolds me that I need to reflash my device with a batt at 100% but i didn't prof that solution so if you like to check that. tell us how is it going.
Hope it was usefull.

question on wm6 and battery

Hi all,
I have installed the WM6.1 ROM 6.1.2a16CS by C. Shekhar on my qtek2020.
It is very cool and gave a second life to my qtek. I am just a bit surprised by the duration of the main battery. It is running out of bat very fast.
As I haven't used my qtek for month before installing the new ROM, I can't tell if it's a battery problem or because this new ROM is consuming more resources. Have you noticed such behavior on your machines?
For further info I am not using my qtek as cell phone. I am thinking about using it back as a phone, but I have first to fix this battery aspect.
Moreover I have read s/t about a battery fix, that I haven't installed yet. Can s/o tell me more about this fix and what it is doing?
Anyway this ROM is a great one.
Thx for your answers
Marc

I dont know about the battery fix but i have never installed any sort of fix like that either for wm5 or wm6.x. Are you sure there isnt some background process that keeps on continuously running? It could be a battery problem if the battery had discharged alot during the non-operational period. I changed by himas battery about 7-8months back because the last battery had gotten abit too old and was discharging very quickly.

i think you are talking about SD card fix..its a registery fix that makes the battery consumption by SD-card low

well, WM5 and WM6.x IMHO are battery consuming ROMs, i can attest to this,
experiment no. 1:
same xda, same battery (1200mAH original battery)
-with WM2003SE at normal use, XDA turns off approx after 36 hrs of use including standby.
-with WM5 and WM6.x, XDA turns off WM5-18hrs, WM6.x-25hrs of use including standby.
experiment no. 2:
two xda, different OS, both with brand new 3600mAH extended life battery.
in 1 day (at heavy texting use from 7am to 7pm):
WM2003SE XDA2 - battery from 100% to 58%
WM6.X XDA2 - battery from 100% to 35%
possible explanation:
WM6.x (WM5) uses more CPU time and Memory resources, plus it probably uses more power in maintaining the persistent storage, hard and soft reset persistent memory.

MODS PLEASE REMOVE THIS POST

Ather, is this fix already in all/most recent releases? If not, can you give us a link? Never heard of it.
I have no battery problems, quite the contrary. My battery life is amazing me. To be honest I tweaked a lot when I started using WM6.x, too much to remember, too much to tell you.
but some parts:
I don't need 24/7 phone connection, Phone Alarm takes care of this for me
Use a bare minimum of today plug-ins
Avoid animations
Close programs except when you seriously do need them in the background

Heya Maggy...its long time since i saw u here.. think maybe month
welcome back ny ways
well that fix was in the Imate website..i have it

!!Read post 14 (maybe solution)!! - Strange Battery Behaviour with battery tools

Hello
I have new diamond 2 for three days. It's very good machine, but i've one serious problem with battery. I try to explain the strange behaviour of it:
1) Battery life is too short. I have read in this forum, that battery life is amazing. I dont have this opinion. My topaz's battery life is about 3/4 of a day (standard using)
2) battery behaviour 1 - sometimes i have battery % value another than after restart. For example i have now 50%. When i do soft reset i will have 35%. After second soft reset i will have 42%. Maybe i have problem with battery calibration or something like that. Or ROM is bad.
3) battery behaviour 2 - many times my battery freeze at specific % value (for examlple 40%). At first i though that is amazing battery life. Buuut no. After few hours still was there value 40%. So i tried soft reset and i saw only 16%. I really don't know what is this problem about.
I tried ariel battery bar, which is very simple program and i didn't have problems with it in the past (when i had kaiser). But here was the same problem. Value on Ariel battery bar freezed too. After softreset there was another value. Maybe i will try hard reset in the future....Now i am trying to format battery with process of fully charge and discharge. Maybe it helps.
Has someone the same problem like me?
Detail of my official ROM:
ROM ver: 1.39.479.1 (47382) WWE
ROM date: 04/07/09
Radio ver: 3.43.25.19
Protocol ver: 61.20t.25.10U
Many thanks for help
PS: i had hermes, 2x kaisers in my past, but this kind of problem i haven't had til now. hmmm

Can you list any applications you have installed or is it still original and out of the box with no applications apart from the standard ones?
How did you perform your initial charge ?
I always perform mine by doing a full charge - letting it drain and then back on charge
This happens for the first week - even if it goes flat in the car, I will not plug it in the car charger until I get home and can do a full charge!
Once the first week is done, I charge normally which at the moment has been every 2 days
Did you do something similar?
I have read on here someone else having issues which is potentially down to the battery so it might just be you have a duff battery

thank you for quick response
Apps:
G-alarm
Total Commander
Core Player
Dictionary
MyLight
Nothing special installed. I think at first i must do a hard reset because i must exactly know if this will be on fresh ROM.
First charge - as usually - it was the same like you.
Now i am charging and here is the same strange problem. I am charging now for 2 hour and battery is only on level 50%. So, now i am going to do soft-reset..............few second...................tadaaaa i have 100%. This is not normal. Here is something bad.
But thanks for you help.

I was going to suggest the hard reset route - this would determine if its software or not.
I will say that charging from empty takes a hell of a long time on the TD2! I'm thinking without even timing it, that it is taking around 4-5 hours to charge up ... and thats on mains!
Are you doing a soft-reset while it is plugged into the mains to charge?
Also is it doing this on usb charge (try another cable and NOT the one supplied for the charger)

Have you been using Opera. If so how have you been closing it. Did you go to menue exit or just hit the X? I ask because I found that hitting the X did not fully close it and when I went back to it it was still at the same page and not relaoding my home page.
Also did you set X to close the programs automatically or do you have to hold X to shut the program down?
It is also my 3rd day with the phone but have used internet a lot and the battery seems to be good. I also have been playing lots of games. I have done an initial Full charge and let it drain.... A full charge again let it drain... and last night it got a full charge.... My battery is Full at the moment. Today I have used it mildly for the web.... Like less than 15 min and have played games for about 10. A few calls and that's it. I can say it's doing better than my Elfin has.

Good point - Just for your reference, in the settings menu > advanced settings> System> Task Manager > Button tab
You can set the X to close rather than minimise - I have always set this to be the case so that when I close a program, it does close!

i tried 3 different chargers. Nothing.
Now i am doing hard-reset. Soon i will report.

report-after hardreseting my topaz seems to be fine. Before hardresseting i fully charged my battery. now i am testing it...

hmmm. really interesting. after few hours of testing everything was ok. So i decided to test it with battery applications (ariel battery bar and another tools wich shows battery bar in %.) And here started ainigain the same problems. Can someone test ariel battery bar and test some soft reset? Please watch what happend after restarts with battery %. I tried 10x restart
and everytime was there another value of battery. Sometimes higher, sometimes lower values.....really annoying
Now i have uninstalled all battery tools and i am going to test again if everything is goog...

alkapone please inform us about the results because i kinda have the same problem here, and i am using batti.
i have a lot of applications installed (nothing to do with the battery meter), but i have GPRS not 3G signal, i am closing the programs normally, and i am exiting opera, and so on. i am using it a lot but i think it goes out kinda fast. i almost get 1 day by using it.
can anyone suggest a battery meter that actually works fine? i like batti

Same problems here! Looking at the battery-information tab: After 4 hours of use after full charged the battery is empty..

I have been using dciBattery and qwertyMemory and all seems to be ok.
I have copied the files to the storage card then run the files and set a shortcut in the windows startup folder.
Here is a link to the files
http://freewareppc.com/utilities/qwertymemoryanddcibattery.shtml

this program doesn't have any config ? i don't want to have the memory bar and i don't want to have that gradient thing.

i think i solve the problem - not sure for 100%
hello to all
i think i solved the trouble. when i have uninstalled every battery app, everything seems to be ok. and one statistic - i had today at 12:00(lunch) 20% of battery. after 8 hours standard using of the phone(few calls,sms,internet), my battery told me that it has 10%. i think it is veeeery gooood (8 hours=only 10% decrease of the battery).beautiful.
result - this case showed that some battery apps/tools causes problens with compatibility battery meter vs. these apps..,
list of apps which causes problems (my tests)
1) jimmyes greens battery fixes
2) ariel batrery bar
3) batti
this is not 100% solution. i am still testing.
please write your opinion.

i am going to try finix

Do you think nueDynamicClock and nueClock as well as TweakHD (with it's apparent powersaving options etc) could be culprits as well? I'm on 6 hours standby and 2 hours device usage and I've just hit 55% on my battery (trying out the app alkapone02 just linked to)

i have installed finix batt icon too. batti was battery crazy on this.
i will test tomorrow, i am fully charging it now and i am going to test how long it will last through the week

super. please test it and report here as usually. thanks

Hi power consumption with clean rom

Hello i recently bought an older xperia x1. The problem is that the battery is emty in really shor time (10 hours), so i bought a new one. But the problem is the same.
I tried Kovsky unoff rom, also official rom.
Also tried clean rom with nothing installed and no settings changed, also some power management apps for win mobile.
Everything is turned off, wifi, data connection...
abcPowermeter shows 150mA power consumption, also when display is off.
taskmanager shows only 5-10% CPU usage for gwes.exe, i think thats normal when rendering results from taskmanager and all other CPU is for idle process.
I dunno what to try to solve this problem. Any ideas ?

My guess is you are running an always active program (like an IM program) that is sucking juice.
You may want to do a clean install and run it for a couple of days. See if the problem is your hardware or if it is that some software is the cause.
My battery life has improved from about 11-12 hours to about 48 hours after removing Palringo from my startup folder.
Also you mentioned you tried a clean ROM with no installed programs. If you didn't install any and you consistently have short battery time you have a hardware issue. Do the hard-reset, flash, hard-reset to ensure a clean install. Use a good ROM and do not install any apps. If after 4 days you still have short battery life then either your battery is dying (or generic and bad quality) or you have a hardware fault.

i tried hard-reset, flash, hard-reset. No changes

150ma idle is quite high IMHO. I run a test before because someone question my roms' battery usage and it should be around 80ma idle. http://forum.xda-developers.com/showthread.php?p=4784976&highlight=battery#post4784976
1. load the same radio.
2. Install Homescreen ++
3. Follow the conditions I tested over that post and see what you got.
Make sure you are in an area with good GSM signal too. Bad signal could lead your phone use a lot more power.
BTW, I found FDC task manager may not report real CPU usage especially if problem with services.exe. Try Memmaid to read CPU usage.

That acbpowermeter is a cool app. I never realized the panel I was using used so much power, and I didn't think having wifi on would consume as much as it did. Right now I'm using the WM6.1 that came with my phone and using the SonyEricsson panel with wifi off, and I'm getting an average of 70-80mA with the display on. Is this a good number?
I was looking into flashing to a 6.5 rom. Would I be getting better or similar battery consumption than the 6.1? If not, I think I'd rather just stay on 6.1 and customize my today screen with some eye candy, etc.

@jackleung
tried your radio with your rom, power consumption is even bigger, than in stock rom
