Hi to all,
I, among some others am experiencing battery drain since upgrading to WM6 even though I am running under the same circumstances as before the upgrade with just a few less programs running etc. If anyone can shed any light on a fix for this or suggestions (turning off bluetooth has no great effect) then I would gladly like to hear them.
I know Malik is also experiencing the problem so I know I am not alone.
Thanks.
I am experiencing the exactly the same great battery usage rates between faria, super rom, and wm6. All overclocked at 260.

when u overlock a device it drains the battery much much faster then u expect so to help that don't overlock but if u overlock then the battery goes mad because overlocking takes great deal of amount out to make the device faster.

I overclocked to 264 (omap) / 286 (bs) MHz without issues. It seems the cpu drains the batt a lot only during "heavy" task execution, e.g. playing a game or watching a movie that is not adapted to qvga. Most of time it just sleeping, as before.
So, i flashed wm6 (pdaviet v.3) and have noticed the same or even less battery drain as before (when my wizard is left alone). You have to check all you're installed to fugure out "the swine"

i have it overclocked to 299 with batterystatus, and no battery drain... the OS isntalled is pdaviet v2 ...
If anything, I've found WM6 to be *better* on battery life than any of the previous WM5 AKUs.
AKU 3.3 would be the best in the WM5 range.
I've also found that the battery life on my device has dramatically increased. I don't have to charge it now for about an extra two days compared to before.
This has been an issue with me as well. I'm running the clean Crossbow ROM (aka Orwells1984 et.al.) Here are the programs I have been running:
2.19 radio rom
Resco Med. Suite 5.42
Pocket Weather
Sprite Backup
Smartskey
Omapclock @ 240mhz
CE Star
I had issues with the today plugin from Resco cutting down my battery life on the old iPAQ 6365. Haven't had ANY problems with previous AKU 3.x versions.
If you're using omapclockplus your device is at normal speeds during standby. I think its the crossbow radio that drains it. Switching between OSs might not change your rom, leaving the battery drain

maybe it really is the radio... i moved to 2.17 and since then no battery problems, but im not for sure its that, but possibly since i have same apps installed on fresh WM6 as before when i had battery probs.
Well, I finally did a hard reset and lo and behold the battery drain problem is gone. I had it off the charger for most of the day and kept the WiFi on a bit as well. The ROM on which I really noticed the problem was the Pdaviet3. I'm going to reinstall the Resco Today plugin and see if that does anything. I love this ROM. Clean and fast!
try disconnect "Error reporting". It's on by default.

Weird.. I did this last night too and it seems to have cured the problem...
Anyway I still have the automatic power up issue... Is there a solution other than locking the device? i.e. A registry edit to turn off push email?
I think the battery drain problem MAY have been solved by the hard reset as well.
Tomorrow will be my second day of use since hard reset so I will report my findings.
I remember (when I had Motorola MP220) advice for longer battery life: device should be 100% charged when flashing new ROM. If not, charge it 100% and do the hard reset.
BTW, I had battery drain with Pdaviet ROM v3, 'cose the smatskey was set for overclocking by default.
i own a xda mini s with crossbow (orwells ROM and Radio 1.19), i use direct push and don't have any battery problem.
Had the same problem: batter drained 2 or 3 times as fast as regularly.
Used:
- TomTom6
- SPB Weather
- PocketPC Wakeup
- Resco todayplugin
- Todaytime
Just did a hard reset and reinstalled TomTom & SPB weather.
Everything ran fine, til I installed PocketPC Wakeup.CAB...
So that one might be the problem....
Anyone else tested their software for batterydraining problems?
batterystatus might also be a problem.
I hard reset, did not install batterystatus but installed rest of my normal apps; this solved both my wakeup issues and battery drain issues.
P.S. simply uninstalling batterystatus did nothing, had to reset.
No batterystatus is not the cause because the first time when I had the issue was without batterystatus ever being installed. The problem hasn't really been back even though I now have it installed.
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.
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
Simple Poll.
Have you seen a decrease or increase?
Someone can explain this battery drain?
in a lot of roms based on 2.2.1 there is a big battery drain, in some other there isn't.

Reboot after unplugging from USB and battery drain is gone. For further improvement install SetCPU and reduce min/max frequency. I am getting more or less the same lifetime as with donut ROMs.

OK I have done.. but the problem is that when I use it 3 o 4 minutes (for example I install an application using a file explorer, then I read a message and then I come back to home) m battery get 5% lower...
In standby I lose 10% in 6 - 7 hours (I think this is normal).

I am currently without a computer therefore immune to this USB bug. I flashed CM6.1 to this and the other g1 and both suffered substaintial amounts of battery drain so I nandroid restored back to CSDIv4 and still the lowest frequencies and settings did little to combat the descending digits. So I tried this...
Recalibrated my battery
Flashed SuperWipe.zip
Reboot
Flashed SparksMod's latest
Reboot
Wiped battery stats
Unplugged...reboot
Battery lasted 23 hours the first day never seen anything like it.
Lifes great.

I'm using TMUS-G1-Froyo CM6 remix..
and I'm using the new radio with +14mb.
The rom flies but the battery go down too fast.
I'm using setCPU with 256 - 528 mhz while screen is on, 122 - 256 mhz while screen off.
If I go to battery use in settings I see
Cell standby 45%
display 28%
phone idle 22%
android system 3%
I don't think is normal... cell standby is the battery use by cell radio..
I wonder if the new radio give a big battery drain..

I got real excited when I heard about the new radio and hboot even thought that its exclusion was the source of the the battery issues. Haven't been able to try it as I'm without a up-to-date PC at the moment.
It would be real nice if I could find a seasoned dev who understands battery consumption. I thought the kernal was the main culprit but I've tried two different roms with the same kernal and one has notably better battery life than the other. So confusing.
Sent from my HTC Grandaddy via XDA app
I can't use my phone with this battery drain...
I will come back to official android OTA-AOSP 1.6.. with +14mb.
So I'll test if this kernel with 14mb is a cause of battery drain.
PS: I'm not a lover of rom customizations.. I think the official roms are the best.
The other are all too heavy. I'm not a fan of cm kernel, that is too heavy for g1.
I would see an official OTA 2.2 without customizations, so every one could customize as he want, and if he want.
PS: OK I flashed AOSP 1.6 using ezBiff_kernel to have 15mb (cause I have new radio and spl, so I can flash roms only using this kernel).
Result: my battery life is similar to froyo 2.2 roms... so the problem is:
1) Kernel? (ezBiff_kernel is based on cyanomod kernel... ... ... heavy as death)
2) New radio/spl?
3) My battery (I don't think so.. it's new battery. I buy it 2 weeks ago and in the beginning it works so well.. but then I flashed new radio/spl and new kernel for 15mb..)

Come now.. the cm pershoot kernels are super optimized so they don't collapse under the heavy as death rom that is usually on top of it..
I get mixed results with that kernel between testing and feedback.
A test phone can idle on wifi+2g for days on the stock g1 battery even after a usb unplug.. but on more common use with syncing services its not performing as well as I'd like..
Some of it is fixed with less swap/compcache or changing clock speeds 122/480 for most the speed but lower voltage levels. Also the interactive governor may work better.. I'm testing these ideas if results are good my next kernels defaults will use them.
Cm/pershoot have some interesting new power management code from other htc devices.. So hopefully soon all will be better. (I merged most of it to my kernel but there are some loose ends.. works well untill the phone locks up.. so no public release yet)

Ok sorry I talk without knowledge. I really don't know the effect of the cm kernel. I only know that all roms based on cm release, with cm kernel, are so heavy and slow.
I like your rom (2.2.1 AOSP) and I love your new way to get 14mb.
But I have this orrible problem. My phone has a lot of battery drain when I use it. With screen off, no problems.
I have never used swap or compcache in this days, and I also try different clock speeds (not over 528mhz).
The result is that when I unlock my phone, I go to settings, I see for example 95% battery. Ok, I return to home, I open a message, I return to home, I open contacts and I scroll some contacts without make calls.
Then I come back to battery settings and I see that is 92-93%..
in 2 minutes of soft use.. I think this is impossible. If I open stupids 2D games... ahah in 5-10 minutes my battery lose 10 - 20%.
I remember 1 year ago, with 1.6 (no cyanomod) my battery was good.
Now it isn't (I have a new battery).
Today I flashed aosp 1.6 with your kernel for 14mb (I have new radio&spl) but nothing... I lose a lot of battery percent as in froyo.
So I think problem is or battery calibration, or something to wipe, or cm kernel, or new radio&spl + your new kernel...
Now I'm recalibrating battery (is at 1% from 2 hours, I'm not using it.. ) then I will recharge for 8 - 9 hours and then wipe battery state, but I have done this process a lot of time without a benefit.
I'll try to remove the new radio+spl (so also using standard kernel) if my battery continue to lose percents so fast.
I'll keep you update on my "story".
PS: Sorry for my bad english!! XD
OK.. after a day of low discharging and a night of 8 hour of recharging, I wiped battery states, I wiped data-cache-ext ecc... I flashed aosp 1.6 and ezbiff kernel..
"battery drain" continue...
I will try tomorrow to reflash death-spl and old radio..
BTW, is normal for hours battery 4v at 90%?
On the back of the battery sais 3.7v... I thought 3.7 was the voltage for 100%
Update
I know this thread is a little old, but I ran into this problem as well. What I found was that the official US radio (2.22.23.02) used considerably more battery than the international one (2.22.19.26i). The other thing I noticed is that switching to "use 2G networks only" in mobile networks settings and disabling data over mobile drastically improved battery life.
I also noticed that wifi used a fair bit of juice so my recommendation is to disable wifi if you're going to be on the go for a bit, and disable data/3g if you're just going to be hanging out in the local webcafe, your/a friend's house, or some other location with wifi access for a while.
If you wanted to be ambitious and cared enough you could write a script to use as a shortcut on the home screen to do the swap automatically (detect which setting(s) are enabled and swap them to the opposite).
With those changes, you should get much better battery life. My thoughts on different Froyo flavors is that possibly different builds have different settings by default. Cyanogen comes with data and 3g enabled by default so this will quickly suck out your battery if you're running your 3g, 2g and wifi antennas all at once.
The stock build (1.6) got about the same battery life as I'm getting now with those settings applied. With either build, having all antennas on all the time will drain your battery very rapidly. Being a little more cognizant of the settings (perhaps you also had it set to 2g only on the stock build) you're using will significantly improve your battery life. And when I say significantly, I mean night and day (but the antenna version definitely does also make a difference... at least in my case).
Hello to all,
I have two problems that are almost making me go back to stock 4.3 ROM
The first is related to the battery, the android system appears first with 25% + battery drain, and in most cases equal to or greater than the battery consumption of the screen! This makes my battery does not pass a day, and the stock I went much further (without STAMINA MODE).
The second issue is regarding the performance measured by AnTuTu. I know that does not mean much, but in the STOCK I get 25.5k and I read out there that people also manages the same in CM11 LBL (the MrSteve555 and also bagyusz), I do not understand why I can here the maximum 22.5K .
Independent of ROM I have put the same results. Tested in all versions of MrSteve555 and in the last two of bagyusz. Also tested in the PAC-man RC-1 neXus PRIME, same result and battery consumption.
In all ROMs I wipe system, data, cache, dalvik cache.
Does anyone have any idea how to solve this? I am discouraged because I love the CM11.
Ps: I use .207 kernel and I've tried with .205 also, same result. (I have LBL)
Damn what is that screenshot supposed to show?? 30 minutes off charge and it is at 99%!!! It's obvious that the screen consumption will be minimum, it was on for a minute or so probably... I know that usually android system drain is higher in cm than stock but you should compare your battery stats at the end of the day...
Please reset the counter by tapping on the trash icon on the activity bar. Then please post a screenshot after hours of usage. This will enable other people to properly interpret your battery stats.
Some tips though, you will most likely encounter a slight battery drain while using custom ROMs. This is due to the fact that stock ROM and custom ROM works differently. You might actually having a normal drain than a supposedly "bad" one.
By the end of the day will be the same... Anyway I will post later.
I attached new images for better understanding.
Does anyone have any idea?
Firstly, Antutu scores mean sh*t...
In the past I've had allot of ROMs with very bad Antutu scores which performed much better in terms of speed and general user experience than a standard ROM with higher Antutu score.
Furthermore, install better battery stats or any other wakelock detector app to see what is draining your battery. The pictures you are showing us now don't help at all.
I've exactly the same problem, android consumes always more than 25% battery too...

As I mentioned above, you need to identify what is causing the wakelocks first. Untill then there's absolutely no solution that can be presented to both of you.
By pointed by Gamm86, it might be due to wakelocks. Once the wakelocks are found, you may use Greenify to hibernate that rogue app. When the app is selected within Greenify, you will find it easier to see the wakeup path and cut it off through Greenify.

It's not always apps themselves that cause wakelocks.
Background services related to phone or app settings are usually the culprits, meaning greenify won't resolve all wakelocks.

yes I understand. Hmm i believe you are more experienced in this matter. Would you tell me how to stop those wakelocks that caused from other services? I would really appreciate that, cause I find many people solve this problem but they never did expose where they learn from or the methods they use. and yea, I've googled but I got nothing

Use Disable service app. Check which wakelock is occurring and disable that service.
Or get the donate version of unbounce and delay the wakelocks like every hour or so.
I already use Greenify and hibernate all apps that are not chat, not solved.
I also noticed that while I sleep and the phone remains idle the android system does not consume a lot of battery, something around 6%, but when you turn on the screen and the phone is active it starts to drain. So the problem is not in the wakelock, but elsewhere.
I'm using the applications suggested to post new screenshots later.
I used the apps for a day and I'm posting the screenshots of the result ... the system keeps draining and I don't see any information that would help me on the images.
Anyone have any ideas?

I'm on MrSteve555's CM for LBL and was also wondering why I was getting a much lower AnTuTu score than stock. Then I discovered that I get 22.5K scores WHEN CHARGING and 25.5K scores running off the battery!

I have noticed the same issues on all 4.4.x based roms (slimkat, pac, PA etc.). The only fix i found was to disable the automatic screen brightness. After disabling it the system_server service became normal and Android System dropped to 9-8% of overall battery consumption.
Good luck
