Hello,
I'm currently experiencing an unexplained battery drainage issue and need some ideas from you all! I used to get a battery drain from the phone while it was asleep and connected to my wifi of -10 to -14Ma, where as I now get -76Ma! I'm using "Current Widget" from the market to monitor battery usage which is logged to a file. I have no idea where the additional % is coming from and after exhaustive testing over the last day I'm beginning to go out of my mind here... The phone is consuming too much battery while idle and therefore running flat far too quickly.
I can't quite determine when this started to happen. I'm running LBC v0.5.4 and have been for ages, I upgraded to the latest radio 06.02.03_M although I've tried reverting radios to most of the older ones and can't seem to loose the problem. I've completely reset the device, using the WIPE script (format commands) and installed fresh LBC v0.5.3 and v0.5.4, after the initial install I get the minimal drain (-10Ma) to start with but after the first device reboot its back up -76Ma, this happens both with & without a google accounts configured.
I have no additional applications installed from the market and am installing only current widget from its apk. AUTO-SYNC is off. I've even tried multiple full resets, re-flashes of the ROM, differing kernels, multiple Radios and setup using a different google account (my wifes) and the same thing STILL happens.
It can't be the router related as my wife phone a brand new DESIRE S (still running STOCK) is getting -16Ma from the same router, which I have rebooted. It can't be current widget as I'm running the same apk that my wife is and she isn't getting the problem, plus I've run it for months now and not seen this drain!
I'm considering going back to STOCK! which can't be good. Please help....any ideas and/or suggestions welcome.....(except use my wifes phone!) I must be missing something?
If you can't think of anything that I'm missing, could you at least state the ROM & RADIO version that you're using and the battery consumption that you get in a similar state.
have you tried deleting the file battery_history.txt on your SD card?

I only have a currentwidget.log file on the SD card that's produced by the Current Widget application and I've tried removing that a couple of times with no effect.
What produces battery_history.txt? isn't that another battery consumption application?
It's the Battery Monitor Widget. Try that and report the results.

Opps I thought you were refering to battery monitor widget
Try battery monitor widget like shrome suggested
Other than the reading how is the battery life doing,it is possible that the reported reading is incorrect ,if the reading is right your device should be out of battery very fast

No problem...
The battery life unfortunately does seem to be reduced. I have always had that widget on my main home screen so notice its reading whenever I'm operating the device for months now and its normally accurate which is why I spotted the change.
Although I'll be honest since I spotted the change in the reading I've been constantly flashing, wiping, restoring etc which are all heavy operations on the battery life so its really difficult to tell.
Next time the battery hits 100% charged I'll also re-calibrate.
EDIT: Have wiped battery stats from recovery
EDIT2: Have switched and am now testing with battery monitor widget, will report back

Is your device getting heated ?
Have you tried switching battery & the sim card with the other DS you have?

Have again fully wiped, reset and re-flashed LBC v0.5.3. I configured no accounts and turned off auto sync. Flashed v0.5.4 update and am running with the latest RADIO (20.28I.30.085AU_3805.06.02.03)
No applications installed except Battery Monitor Widget. No screens contain any widgets apart from the clock.
My device is clocking battery consumption figures of -36mA to 100mA...
Yet my wife's new (STOCK 1.30)) with 03.02.11 radio is clocking just -7mA!

My device isn't particularly warm.
Although good call on swapping Battery and SIM I'm doing that now, just one at a time in the hope that it is one of these then I'm able to identify which one
EDIT: rather than change too many things at once I'll also try a different SD card in mine after these initial tests.

OK, this is downright weird. The issue is probably in the kernel, not Radio. Try switching kernels, go to Unity V2.
EDIT: This may be a hardware issue. I think i read your wife has a desire s. Try switching batteries.

LBC mod 5.4 comes with unity v2 kernel as default
& also it can't be a software problem as he has been using the device with the same setup before without a problem

Correct, I tried switching kernels back to stock earlier and saw no difference.
Swapped SIMs and saw no noticeable difference the new device was still clocking incredibly low numbers.....<10mA whereas mine (with her SIM) still clocked ~50mA
Swapping batteries now.
what's the reading on your wift's battery?
If all else fails, try switching ROMs altogether. Go to virtuous unity. Aosp roms have battery drain, so you won't have any luck on those. Maybe an upcoming update of lbc mod fixes this issue.
mind trying and tell us your reading?my friend who's on hd2 android has reading around 1-4 mA..

1-4 mAH ?!?!?!?! This is freakin impossible on desire s. 7-10 is normal. I think he posted in the first post.
Edit: ok, this is a shot in the dark. My friend on Virtuous ha similar readings, so i was following this closely. Turns out, he was checking the widget rather than the file in te sdcard (battery_history.txt) the file shows the stats for when the phone is asleep. Check carefully. The widget will usually show 70-100 mAh, as while checking the widget, the phone is awake.

Was still testing, as I need to collect a few continuous minutes of screen off testing to make it fair.
Although as you mention in the LBC thread. which hopefully shows that this can't be a hardware issue with my device, unless it's from the w-ifi attena itself?
If I swicth off the wi-fi completely on both devices, which I've just done then the drain disappears from my device and it starts clocking ~13mA, although hers is still consistently putting in 7mA.
Now time to try a new SD card in mine, must try that before reverting to stock ROM.

Easy....he said his friend with a HD2, its a known fact that there is a battery drain issue on the DS as if you were to compare its drain to that on the old Desire its over twice the idle.
There are plenty of threads early on covering this issue....although none of them ever identified any reason. Its interesting to see what the CM7 ROM can achieve in this respect.
Newer processor = more battery consumption

Fair call....but unfortunately I'm checking both but only rely on the results from the file.
Is it just me or does the Sensation use A LOT of battery consumption on "Display"?
Just moved over from the desire and the phone is pretty good, only downer is the battery life really sucked. Checked the power consumption and shows me 3 items using the battery "Cell Standby" - 4%, "Phone Idle" 3% and "display" 90/96%. Using the latest AndroidRevolution custom rom and updated to the recommended radio, my Desire is running the latest version of leeroid and the display only takes 14%.
Any help would be great, did I install my rom incorrectly? I've already got S-off and recovery installed.
Would be great to have my phone run for more then 3 hours, always have to bring my Desire just incase my main dies
I am just stock and it is around 75% of the battery most days. I still get through a full day on a charge. Just a feeling that it is using around the same as my EVO did, but it doesn't report all the "phone" activities like processes and stuff, so it correlates to a higher reported value.
Just my two cents.

Oh, I kinda lost my stock rom when I partitioned the Memstick and forgot to back everything up on it which was a stupid thing. I usually have it on power save mode when Im at work but it still drains heaps. Not sure what the problem is, If there's a link for the stock rom that would be great. A rom for Australia/Vodafone would be preferable
Would like to keep the Revolution since it has the beats software but I'd probably prefer to fix the battery problem, 3ish hours is horrible. Cant really use it for anything. Anyone else know how to fix this problem?
Maybe this is due to my lack of experience, but maybe not. It seems like every time I put a new ROM on my phone it goes to hell in about a month. I'm not a technician but I can follow directions for installation, patches, etc. So far I have had 0 long term success in installing a ROM that ends up being any better than stock after 30-60 days.
For example, I've had issues with battery drain, random booting while the phone is powered off, redraw issues, serious lag, data connectivity issues, and a few other things. It seems like its always something.
The only phones I've toyed with are my old Eris and my Charge. Is this a phone issue, noob issue, or is this par for the course? If it is par I'll end up back at stock and have mediocre performance rather than have a buzz saw that ends up needing constant tweaking and maintenance.
Btw this isn't a knock on developers. I appreciate them sharing all their hard work. I just want to know if everybody else goes through this or am I holding a bag of stupid.
Just rooting does nothing more than give you superuser access. It doesn't even do anything that uses the root specifically. Different roms do different things, but nothing to use battery...mostly they take things out rather than put things in.
Best thing to do is look at BetterBatteryStats and track partial wakelocks. That will tell you what is waking up your system and if there's anything spiking it, you can deal with it. Most of what really drains battery on this phone, other than bad apps, is somewhat random, and it will affect non-rooted phones just as much as rooted.
Must be something you did, picking a good rom make a big different. In my case. I flashed tweakstock to my daughter's phone since the first day it released (with tweakstock kernel), and never, I repeat never have any issue, when tweakstock 1.4 released, this is the second time I touch her phone and up until now she hasn't have any issue. If you use eclipse rom, PBJ kernel, Imonsey kernel, you're going to have issue. They are not bad roms or kernels, but they do have bugs. This is my experience.
Yeah, I think it's you. On stock, I'll be lucky to get 12 hours usage in a low signal environment. On a custom ROM, with custom kernel, I'll make it through the day. Of course, I've had a couple of random total crashes where I had to go at it again, but I deal with it.
PROTIP: the Facebook app needs to be told to stfu constantly. I would get an app like System so you can kill it easily-it still stays in RAM and in wakelock, taking clock cycles, even if you close it by backing out. I found that this was one of the best battery savers.

Yes, I agreed with kvswim, Facebook is a big battery drainer, I ended up using the browser for facebook, it's not as nice as the FB app, but once you get a hang of it. It's fine. I suggest if you want trouble free, ODIN pit file and original factory image, then upgrade to tweakstock with tweakstock kernel, then install Go launcher for smoothness. To save battery even more install battery saver by Antutu.(keep all default settings, don't play with it). You will see big improvement with both battery and smooth trouble free phone.

you really find a battery saver to be helpful. Every time i try one it ends up costing me more battery life than it saves.
As for the phone issues. Are you wiping data, cache, and dalvik before you flash? Not doing so can really muck things up. And a lot of times its just an annoying app that sucks up all ur juice, ie words with friends and facebook. I use them alot so I deal, but u can definitely tell the difference when u dont have those apps installed.
No i dont think its u...i have problems also.i jus made a post about my home/hard key...its always seems to b something after the next.but it looks like people find ways to deal and eventually conquer.also i appreciate wat the developers do.its alot of work and headaches.on top of posting and replying to many many people.its the roms that cause problems...constant tweaking and toying around...alot of times things jus need to b debugged a little it seems.but its all in the nature of what were all doing here.good luck to u

Hey. how about give the "battery saver" app by Antutu a try. This is one of the kind. It does not kill processes like others. It actually readjust cpu frequency during usage and put your phone in heavy deep sleep, after installed, let it run for 2 days, you will notice at least 3-4 hrs more during usage and 10+ if you let your phone sleep. I have test this app with wifi,4g,gps on 24/7 and I still have good battery life.
I downloaded betterbatterysaver to check my stats. Now to figure out how to read the data. Any suggestions? I've searched Google and it seems to be a mystery for many. It appears that Dolphin HD is using most, but I kill the program when I'm done???? I switched to mini and froze HD to troubleshooting. I only use FB browser too. I ditched the app long time ago.
Before I flash I wipe dalvik cache, data, and then wipe it again. I follow directions closely since I can't figure my way out if something goes wrong. I'm running tweakstock's latest right now and I'm really enjoying it. Very stable and snappy. However, the battery problem is killing the experience. It drained fro. 69% to dead in 6 hours overnight! Switched from 1.1 because the phone got very laggy and the hand off between 3-4g was getting dropped and I was losing data connection.
I will try the battery saver app. Just got battery calibrated and still not any better. My need to have a phone that doesn't suck will keep me playing with this thing until I get it right. My Charge is used so much it's like my third hand.

Did you try to disable(freeze) SDM app and also Google service? May need to backup all your apps and do a factory/data reset, If not help, possible to re ODIN factory image (see pos # 5) since you have data drop issue. Some thing is mess up in your OS.
For betterbatterystats look at wakelock and see what process used the most.
If it died overnight then something is definitely eating your battery. Are you in a low signal environment? Go to settings, about phone, then battery usage. If anything besides display is taking more than around 5-10% (can be more if you use it a lot) then that's your main problem. If your cell standby is more than 25% it's the low signal that's killing the battery.

Data is up and running smooth after flashing newest tweakstock. My home has a strong signal and my bedroom is sometimes 4G so I don't believe the signal was low, unless the transition between radios killed it. However, it wasn't a problem 3 weeks ago.
I did freeze SDM and noticed some improvement. Buhohitr, did you mean freeze Google services framework?
Battery usage seems to be normal for now. I am noticing Dolphin is no Singer sucking down 35% or more since I switched to Mini. It doesn't even show up on the list.
I'll see how it goes today and report back on wakelocks. If it doesn't get any Beyer ima Odin to stock and root/flash tweakstock again.
Also, the battery doesn't drain unusually fast wile in use, browsing, music, etc. But when it sits it drains at 3-4% an hour.
I would try manually calibrating your battery. It really worked for me. On average I get about 18-19 hours on one charge with medium to heavy data usage throughout the day. There is a thread in the General section.. I'll post a link in a little bit.

Wiping battery stats is a complete placebo. All the battery stats stores is the state of apps as related to various things that affect battery life (like display on time, screen brightness over time, and wakelock states). It does nothing that will actually affect your battery life one iota. It is actually cleared every time you charge your battery to 100%, so manually wiping it is completely pointless.

I'm well aware of the post of Dianne Hackborn debunking the myth of wiping the battery stats; however, if you actually read the post on the steps to calibrating your battery, it's not just wiping your battery stats. There's actually a few more steps involved. You're right though, if you just wipe the battery stats and expect better battery life you're just wasting your time.

To disable Google Service, go to settings -> location&security and uncheck Google service. Do not freeze Google framework. Also seems like your phone is not in deep sleep, please install "battery saver" by Antutu and let it works for 24 hrs, you should see huge different when your phone is sleeping. BTW what kernel are you using? If you're using PBJ kernel you can install "CPU tuner" to further keep your phone in deep sleep. I'm talking about 1% for 3 hrs sleeping.
I'm curious as to what Battery Saver actually does. The app's market page doesn't say. I'd be curious if it would interfere with my IMAP push email or SetCPU's overclock settings.

I've done that and never seen an actual difference. Like I said before, I have no reason to believe that any of it is anything other than placebo. My normal daily variability in use is more than enough to account for any perceived differences. On top of it all, bump charging is not good for a Li-Ion battery, so if anything, those instructions are a good example of how to lose long-term battery life for short term gain.

Personally, I believe that most of the time the procedure does nothing. I think there are times, though, that corrupt data gets into the battery stats. For instance, I had an app lock up my phone and force a hard boot. When the phone came back up, it showed 22% more battery than it had previously. I believe that bad data such as this can over time affect how Android reads your battery life. In that instance, I believe clearing battery stats would help. I don't think doing it just because a new ROM was flashed actually does anything, though.
I rooted my Sensation 4G for the first time yesterday, and was pretty happy with how smoothly everything went. However, I noticed during normal use today that the battery was being drained faster than usual. It dropped by about %20 within a two hour period - much faster use than during pre-root. I checked things that might have been draining it. But I found nothing new that could've been considered a possible culprit. I'm running the stock rom with Go Launcher EX. Has anyone else experienced this phenomenon after rooting?
Not without flashing a custom rom, and even that's a rarity. Rooting in general does not cause much extra to be run, so battery is virtually unaffected. Try fully discharging the battery and charging it back up to 100% without interruptions during the recharge. That usually clears up battery issues.
A better idea is to completely charge the battery until it is 100% and the led light turns green. Then while the phone is still plugged in go to your recovery menu and wipe the battery stats. This is not a recommended process, its a REQUIRED process every time you switch roms. That should fix the battery issues that you are having.
Thanks, I'll give that a try when this drains out. I also noticed that more RAM is being used now after rooting, which looks to be the result of too many apps opening in the background. It's strange that this didn't happen before either. I'm hoping something didn't go wrong in the rooting process that caused this.

Are you using many apps that require root permission? And the battery stats is only reccomended, some people say its a myth and don't bother, but do it once for every new rom. And give it a few full discharge and recharge cycles before deciding the battery drain is high.

I'm only running BatteryCalibration and Titanium Backup that need root permissions. I'm just seeing more regular apps running now than before. And I've been checking app activity through the Go TaskManager Widget if that means anything. I'll take the advice and calibrate the battery after it's at %100 and give it some time, although I didn't change ROMs yet. Would flashing a ROM and then calibrating have any possible effect on this?

Task managers tend to cause more harm than good, they're okay to monitor but killing apps all the time drains battery. As far as ram usage goes, a good custom rom will work wonders, and depending on which one you pick, the battery should improve too, but as far as calibrating goes its the same on any rom. Most recomend wipes.
When charging to 100% I highly reccomend using an app called current widget, because the battery is out of calibration it won't show an accurate full battery if it won't show an accurate draining one. So use current widget and charge overnight, or as long as you can, leave the phone locked as much as possible and check the mA value every now and then, and even if the phone says 100% wait til the mA reads close to 0, mine usually doesn't show less than 15mA after an overnight charge. Then wipe stats.
Sorry for the essay but I've read a lot about this and current widget seems to be the best tool I've found.

When I calibrate via Battery Calibration after reaching a 0mA remaining charge via that Current Widget, since it takes a full minute or more of heavy lifting to do a real reboot, it's already at 46,000mA by the time i'm back up.
Will the fake/quick reboot i.e. Fast Boot still write the new file?
I think it writes a generic one till it gets real stats. Not sure on this though and I welcome someone to correct me as I have also been interested in this.

People who have performed the calibration: what does your mA meter in the Current Widget read after you boot back up?
also, I think I flashed 1.82 from Scotts collection of kernels after the fact, is this making things worse?
Halp if I don't get to at least 4 hours screen time with such minimal settings (i'm on 20% brightness ffs) I may have to return this beauty
Battery calibration is a myth... FYI... sigh. Are battery are Li-ION base they can't be calibrated. There's multiple factual sites that can confirm this.

Have you tried doing a battery test using htc diag? if not, the process of doing so is as follows:
-Charge your phone to full. (wait till LED light is green)
-Activate airplane mode by going to settings.
-try to kill as much running apps as you can in the background. Don't worry about some of them restarting.
-dial *#*#3424#*#* then select agree.
-select "more" below, and then select battery test. follow the on screen instructions afterward.
-make sure that you check your results exactly after 1 hour later because the screen will stay on even the test is done. So your results might show a different number.
If you get a result lower than 85, you might want to consider exchanging your phone for a new one, or doing a factory reset and trying this test again. In case you are curious, I did the test earlier today to check how mine is doing and got a result of 92. Let us know your results if you indeed do the test.

thank god there's a semi scientific independent way to verify this. ill run it asap. just to be clear, I just read about this test elsewhere and they mentioned a "score" of 85 vs the battery percent being below 85% after completion, can you clarify? does it matter that im already on cleanrom lite 3.0?
im now suspecting the issue is a combination of sense, 4g and spotty wifi coverage a(considering investing in a new bad ass router with dd-wrt aftermarket firmware)

"Screen on" time is going to vary depending on your usage/signal quality/hardware requirements/etc.
My question(s) is, do you let the phone sit on the charger for any amount of time after it has reached a "full" charge? Also, how many charge cycles have you gone through (after installing a new ROM) before you make these assumptions? Do you use WiFi regularly or mostly mobile data? What are your "sync" settings? What is the ratio between your "Screen-on" time to your "Standby/Idle" time?
If you take a look over in the "Battery Stats Thread", you might see that, depending on your usage (and other variables) 4 hours screen time is not that bad.
Also, as others have mentioned, "calibrating" a battery (which is essentially deleting the "battery stats" file) is not necessary.

I let the phone charge to very close to 0mA via current widget
I don't see how a particular ROM needs to learn your battery stats - if calibration isn't necessarily (I do it anyway with a new rom,) what does the ROM have left to learn?
Mix of wifi and mobile
auto syncing one email address + contacts
ratio is at 6.5 (total time/screen on time)
can you comment on the *#*#3424#*#* battery test? is it accurate?

I am not sure if I understood your question correctly. If you could point me to that article that you are talking about, that would help. To answer your question, It doesn't matter what your ROM is. I am running sick sense when I did the test. As for the accuracy of the test and why I said that the baseline score is at least 85, most if not all of the people who performed this test who claimed to have good to great battery life had a score of at least 85. So it is reasonable to think that getting a score that is on par with most rules out the issue of having a faulty battery.
In my opinion, most of the battery issues that us ATT one X owners face, especially those that are in LTE areas are software related. In my knowledge, the main thing that influences the battery life apart from the actual battery is the kernel and the radio. At the moment, we do not have the source for the kernel yet. So, it cannot be truly optimized beyond the current tweaks that are being done by the wonderful devs. Until the source is released, I think that flashing a good radio, (new leaked 2.09 for AT&T) using a cpu editor, and following simple battery saving strategies is the way to go... And before I end this, I just want to mention that calibrating the "battery" is impossible. The only thing that can be calibrated is the "battery meter" on every ROM.

It's not the "ROM" per se, but rather just allowing the phone build "cache".
In other words, when you install a new ROM, sometimes you need to format it first, so all the cached files will be deleted. So when you first use the phone after installing a new ROM you might spend a lot of time re-installing apps and the phone is building cache which takes energy writing the files, not a lot but I feel it might be significant enough to wait until at least the 3rd charge cycle, once you have your apps and widgets set up. For example, the gallery app needs to save the thumbnail cache and so on. I hope that makes sense.
Of course, this would be irrelevant if you were just updating your ROM but I thought I'd mention it anyways. Going back and re-reading your situation I think it might be some other software issue that is draining your battery, not the battery calibration. As for the dial code, I wouldn't know, sorry. Hope you figure it out, I just don't think it's worth the time to stress over "battery calibration/stats", it is more likely a kernel/ROM issue or a hardware issue (the battery itself).

Yeah, what he said.
The cache things makes perfect sense. Happy to report I got a score of 92 percent after the battery test! Now playing with settings. I changed to a new no-lte apn and got really spotty coverage and endless disconnections. Can someone post their best 4g, 3g and 2g apns?
Besides flashing the new 2.0 or whatever kernel can somebody recommend anything else to save battery? A link to a good launcher?

Apex Launcher. It improves battery life quite a bit (in my experience anyways). Also, go through the "Sense" applications, like Weather and Stocks, and make sure you disable sync for them since you can't use the Sense widgets in a 3rd party launcher. You can do it by going to [Settings > Accounts & sync] and selecting each one then making the appropriate changes.
