I've been having general horrible battery problems with my Sensation on stock Sense and Miui.us. I just installed HyperSensation and Faux 0.2.3 kernel with a full wipe and reset the battery calibration thinger.
First 2 charge/drain cycles were yesterday (got around 5.5 hours as has been normal for the last 2 weeks) and after the second drain to 1% I plugged in AC and went to bed. This morning I checked Battery Monitor (not the Beta or paid, so I'm aware the mA reading may be incorrect/offset on Sensation).
The graph overnight shows some odd spikes every 50 minutes draining the battery. This is the first night I've been looking at my graphs so I'm not sure if this is regular or a separate issue from my normal battery hell.
I've included a screenshot of everything I could think of including Battery Monitor and SetCPU profiles. Re running apps, some I've never run before, the only other one on the 2nd page was Thumb Keyboard.
I would really appreciate some ideas on my battery life in general, and what this issue is in particular.
Background:
- Horrible battery problems with my Sensation on stock Sense, Miui.us and now with HyperSensation ROM-CM7.1 with kernel faux123v0.2.3r.
- Been getting around 5-6 hours with normal use, no 3G, no wifi, no GPS, no Bluetooth, low screen brightness, etc etc.
- I also uninstalled Gallery as I was getting the sensor usage issue which I thought may be causing my battery woes, but no dice yet.
- I prefer to keep data on at all times (2G) as that's what I use my phone for, so I don't use this Juice Defender function.
Thanks,

How did you calibrate your battery? Did you..
Flash Rom
Kill battery to 0%
Charge fully 100% then wipe battery stats? Or did you wipe battery stats as you flashed? Thy could be a major problem
Also you have CPU your max set to 1.56ghz when its charged. That could cause the peak in usage. Especially if you have it set to performance and not ondemand. Those are the only two things that's really stand out to me.
Also check the arhd thread. In one of the last pages (depending on when you get this) there is a link for a fix on battery drain on fauxs latest kernel. Check it out
Thanks rddocke, I will check out the kernel fix. I did wipe, flash rom and reset the battery stats at the same time. I will definitely try your method, I didn't realise I had it upside-down.
As for the spikes, they seem to be continuing today, I can post screenshots later. Given that the major battery user is "Adnroid System", would this narrow my issue down to the built in apps?
On the plus side, with the new setup today on my 3rd battery cycle, I am getting better battery life than before aside from the spikes.
ya the spikes could be do to an auto update, maybe background sync... any things could cause it as long as it isnt a constant high usage i wouldnt worry about it. but if you want to help your situation i would set back my cpu max to 19200 when charging, and clock back to 1.2 for daily use, switch your goveners to ondemand and get them off performance.
basically whatever its doing at those times its running at the highest point your cpu can handle. adjusting wont solve your problem but it will reduce the amount of battery it uses
idk its hard to tell android system is always going to be the juicer, that and sense. nonsense for arhd could help you out too. i particularly like sense tho
hope i helped

I'll change these settings as well, great. I feel like I'm getting somewhere gradually, been spinning my wheels for a week on this.
I can't 'thank' you for some reason, but my buddy should have just done it, which is fair since I can finally pester him less about my battery problems and pester other XDA members instead!
No problem buddy glad I could give you some help. Let me know what you discover from all that. Another tip I could give is maybe test out a bricked kernel 1.4rs or 0.91 seem to be working best with sense 3.0 from what I've read
My sensation currently has a power drain that I can't seem to find the cause for. I'm using InsertCoin 3.4.2 with bricked kernel 1.5, using SPB shell 3D launcher, got an Anker battery, running tasker to cut data, wifi, gps, etc whenever the screen is off, setCPU running ondemand with max at 1536mhz and minimum 192mhz, etc, etc.
I fully charged my phone to 100% about two or three hours ago, and it's been pretty much left alone since. It's now down to 68%.
I've got BetterBatteryStats and SystemPanel, both showing nothing untoward, no active tasks, no wakelocks from what I can tell, etc. And according to the standard app for battery monitoring, it shows the various connections have indeed been turning off as intended, and the phone has been asleep nigh on all the time it's supposed to be.
Any ideas what's going on, or how I could look into it deeper?
I've just been playing with the phone pretty much non stop since I started this thread an hour ago, and the battery level is now at 60%. So that means it's actually consuming MORE power when it's not even in use!

Hi,
There is a lot of talk about battery consumption,and it's causes.
Most people will suggest trying a different kernel,or downclock it to 1.2 GHZ.
I've tried different kernels already, and underclocking the cpu seems to make little difference. As I say, setCPU should be knocking it down to 192mhz whenever the screen is off anyway!

Hi,
Is your ROM a 2.3.4 base or 2.3.5 ?
2.3.5 mate. It's InsertCoin 3.4.2, with sense 3.5 (which I'm not using in favour of SPB).

Hi,
I was going to suggest bricked 0.9.1 with a 2.3.4 ROM,because my son has had great results on his Sensation.
I do not know IC well enough to help.
Sorry.
No problem, thanks for your input anyway.

1)Try his new test version of bricked(beta4).
http://code.google.com/p/bricked/downloads/list
2)Charge to 100
3)Turn off, wait till green, unplug and plugin(bump charging)
4)Boot to recovery thru bootloader and wipe battery stats and then reboot unplugged
Drain you battery to 1, then charge up and repeat for a few days. And you can lower the clockspeed since you're using ondemand, you won't see a speed difference with 1.2 and higher. Oh and use ultra smooth rosie so the home will be faster...And see which apps are open in B/G.

With the exception of trying the beta bricked kernel, I've already done all that when I first got my anker battery. It's not a calibration issue, it's that something is actually draining the battery even when it should be asleep.
And that rosie change isn't needed, as I'm not even using sense in the first place. I've got no real issues with how the phone actually performs as everything is already perfectly smooth. The only slight issue I have is since flashing the amaze camera, on rare occasions it can lock up when exiting it, requiring a battery pull to get going again.

Oops missed the part about SPB, I have been having similar issues but with Faux's kernel after using Amaze cam, but I doubt that could cause sleep drain. I think you drain is caused by the phone not entering "Deep Sleep", some rogue app is keeping the phone partially awake and sucking up juice. I'm gonna go on a hunch and say the phone is running around 1.x GHz while screen if off due to the app.

Hopefully mine can help you. I also noticed HUGE battery drain issues in the past using Bricked Kernel, so I then reverted to stock. Battery was GREAT, but the stock kernel blows. So yeah, I went back to bricked and using the 3rd? beta right now. My battery started dropping like crazy again, so I thought it was the kernel. Before, I used bricked and it was fine so again, I couldn't really blame the kernel. What I tried after that is deleteing my OC app (I've used both SetCPU and System Tuner) and since then, battery is great again! You can try this and hopefully it'll help!
Tried that already as I too suspected the OC app a few days ago. Made no improvements to battery life, so I've put it back on today. Not tried a different kernel yet though, as I'd read that the bricked kernel was the best choice with InsertCoin? I used faux123's kernel first of all, but found it ran hot and kept crashing...
Down to 30% now by the way.

That's what I'm suspecting too, but I don't know how to go about finding it. I've looked with SystemPanel and BetterBatteryStats and haven't spotted anything, but that could just be because I'm not 100% on what to look for. And why would setCPU not be overriding it and making it clock down to 192mhz whenever the screen is off anyway? Isn't that it's job?
Then try the stock and see if it's still draining. When I tried stock and everything was great, I just simply assumed that it wasn't an app. It was the kernel!
I'm not convinced it's the kernel though, as if it was then battery life would have been crap ever since I flashed it. It hasn't been, it's only been bad for the past few days. Are there any links to the stock kernel just in case I can't find anything else?
- mine is 24 hrs
- heavy use 16 hrs
. Used some aninations only
. Turn off wifi when not in use
. Used only 20% brightness
. Used juice defender
. Downclock to 1.2 ghz intellideman
And ofc my kernel and rom that im using right now!
Thank me if I helped
I use bricked and i actually got better batter out of it but itsn still not up to par.. However fauxs ran faster but my phone was getting up to 47C... Way too hot.. I don't know why mines running so hot.. Using coredroid 2.6. 1.5 bricked kernel. wiped dalv and cache and battery stats... blah.. any input? i had setcpu and deleted it.
SetCPU is uninstalled again now to see if it was causing anything, and there's still a drain on the battery when it should be sleeping. Does anyone have any tips on how to find what's keeping it awake? It's been fully charged again, been unplugged for just one hour and it's down to 80% battery. Not even been using it apart from me flashing the InsertCoin Bravia addition onto it, making it 3.4.3.
One thing I have noticed though, is that BetterBatteryStats says the RILJ dialler has been running for 5m 33s since it was last charged, 775 times, 8.9%. This is on the partial wakelocks screen, whatever they are. Everything else listed is under 1%, with the only exception being the alarm at 1.6%. What does this mean?
I896, Rooted, factory Gingerbread.
I have a Captivate and a Tab. Both Wifi only, no Sims, Airplane mode on, Bluetooth off. Machines are on but screen is off. The Tab looses 3% over the course of the morning and the Captivate looses 20%!
I'm running regular 'power user' type apps; Titanium Backup, Tasker, LauncherPro. If there are any apps notorious for secret batt consumption, let me know what to avoid.
Running SystemPanel Lite - I can't see any app that is taking up more CPU time than normal that would explain this kind of drain. The battery page shows a good proportion of battery use display and wifi. In one instance I used the Captivate so little that display showed less use than wifi. In the course of just checking phone power consumption, the display use percent way up, just like expected (Just to show that wifi was really doing almost nothing) and still I had lost more than 15% of battery over the time when the phone was supposedly idle, not connected to anything with the screen off. Some ghost is sucking the life out of my battery. Grrrr. What could it be?
I loose 30% in a night with wifi off, backlight set to absolute min and nothing runninng or syncing.
I don't get it. Any ideas? What do I try next?

His tab is running Android too.
If you don't have anything helpful (or knowledgeable) to say don't say anything.
Op, download watchdog from the market, (system panel is kinda ..meh.) and see if there us a rogue app munching battery.
You may consider flashing a ROM see if its just that firmware/kernel reacting to your phone.
Have you tried Juice Defender?
Also, check to make sure you don't have applications constantly running. What version of android are you running? Check in system settings -> status -> somewhere in here you can check the battery status and what applications are pulling the most juice ... From there if one application needs to be removed you can action it ...
Also try the "Battery Calibration" app in the market. It's free.

my captivate running cm7 STOCK will drain down to 20% from being idle for 12 hours
my battery will also drain 30% from 45 mins of wifi only use.
doesnt help him but thats my experience from my captivate
Menu -> Settings -> Wireless and Networking -> Wi-Fi settinngs -> Menu -> Advanced -> Wi-Fi sleep policy
Set it to when screen turns off.
We have to switch that every time we flash. I really wish it was default. Some ROMs also have background data control, but it's usually when wi-fi is on so it shouldn't be a problem.

You do know that cm7 doesn't have the proper hardware drivers from Samsung so the battery life is known to be HORRIBLE right? If not you should really read up on the ROM you're using
Flash any touchwiz ROM, especially a native I897 build and you will see a dramatic increase in battery life.

I'm on CM7 and am going on 27 hours with moderate usage.. Granted, I have the 1800 mah battery from the Sprint Galaxy S2
trying flashing to pinnacle. I too have battled weird captivate drain issues.
if you wanna try CM, read my thread:
http://forum.xda-developers.com/showthread.php?t=1364357
I've held off replying as I was trying a few things and figured I would report only once I was done.
I found and ran Battery Calibration, just before I read the post. Between that and turning Wifi sleep policy to off with screen off, I had a great weekend. I was getting a day and a half out of my phone, which considering the use, was very acceptable. I was getting about the same drain as my Tab. I had 1% battery drain after 4 hrs of screen off time. That seemed fine for me.
I got back to school where I teach and yesterday the phone drained as fast as it has before. Interestingly, it continued its rapid drain even after I left the school and went back home. So, it died at 4am this morning. I heard it shut down. The school has at least 4 routers, two of which have 5k access options. I know if I choose them, my laptop drains way faster. Is there a way to limit my wifi connection on the captivate and not use the faster 5k connection?
But, this still doesn't explain why, even after I leave the school, the Captivate continues to drain when it is 10ft from a single 100mb wifi router.
I'm almost ready to try a custom Rom, but not sure how that will affect my ability to use it as a phone, once I get my Sim activated. Still new to this all.
You think everyone running a custom ROM doesn't use the phone?
Shouldn't affect your ability to do anything...
The WiFi and cell radio do increase power on lower signal as we know, but that's not always the cause of drain. I remember times using Froyo when kswapd goes nuts for no reason, or trillian, email, twitter or some other app just starts using massive CPU. Many apps are probably never tested on a system that has no connection most of the time. That's where all the utilities come in handy to find the culpret. OSMonitor can help find CPU hogs. TiBu can freeze apps, or uninstall them temporarily. Juice Plotter can monitor drain over time (newer Androids have something like it built-in). It takes some time to find it, but newer versions of the OS make it easier and have less trouble.
Also the battery % is only estimated. I'd trust full to empty time rather than 90% to 80% time as 10% use since it's not really as linear as we think.
Not to point out the obvious, but it can be the battery itself that has the problem. They aren't exactly manufactured to NASA standards... well, maybe their standards lately, but the point is, sometimes the ghost you're chasing is staring you right in the face.
Running ARHD 6.5.3 XE...noticing the battery is horrendous. Went to sleep and battery was at 48%. When I woke up 7 hours later battery was at 4%. The phone was idle the whole night. This seems like crazy battery drain. I have nothing to compare to because I got the Sensation about 4 days ago and the second I got home with it it was rooted and ARHD XE ICS was installed onto it. My previous phone was the T-Mo G2x which had terrible battery but nowhere close to the drain I am seeing with the Sensation running ARHD 6.5.3 ICS with Sebastian kernel at 1.6 ghz. Using SetCPU with ondemand governor 192 min and 1.6 max. Screen off profile with 192 min and 1 ghz max. Any idea or suggestions are greatly appreciated!!
Seems excessive, you could try battery monitor widget pro and/or system tuner pro to see what processes are running and record the state of your phone e.g. wifi on, awake, GPS, data etc.
What are the percentages if you look in battery usage in settings?

Maybe it's the cause of overclock. I use hypernonsense (great rom, too bad its discontinued), and it has pretty good battery life until I installed the overclock kernel. I still keep it because it's a lot faster.
Still, the battery shouldn't drain that much. I would try to remove the overclock to see if it's still that bad. If not much improvement, I would try to install another rom.
I don't want to make a new thread about battery life, can I ask here ?
Previously I was running on 6.5.3 XE w/ Seb 1.6Ghz.
Check out the screenshots,during that time wifi and data plan is on,auto-sync with 2 gmails,twitter,FB and weather.Does it sucks or is this normal ? I'm using stock battery.
You want that screen off profile to be much lower - I have mine at 300MHz powersave governor (that way it isn't constantly polling) with no noticable loss of responsivity when I switch the screen on. Then fully charge the battery and reset the battery stats from within ClockworkMod or 4ext
Also, I'd highly recommend JuiceDefender Ultimate - it's really customizeable for things like only activating 3G when screen is on or when in certain apps, then switches it on for a min every so often when the screen is off to check emails etc.
Hope that helps/makes sense!

If you haven't already, get SetCPU and create some profiles:
Screen off: 300Mhz governor powersave
I also have progressively lower clock speeds as the battery life diminishes.

We have the same issue since i bought my phone few months ago (I even try insertcoin and ARHD because of the problem, but no changes).
I've read through the forum and i think the culprit is the stock battery. I'm ordering Anker 1900mAh (it has good feeback) for replacement and i'll let you know if there's any differences.
Can no frills do profiles? I heard to use that with ARHD instead of SetCPU.
i use no frills, for me its the best cpu app, you just set your desired speed, and thats it. no fancy stuff just plain and simple..
Im also on ARHD 6.5.3 with overclocking to 1.6, governer is on demand... I can get between 36-48 hours on a full charge...
Screen is using a high proportion, turn the brightness down some if you haven't already. Mine is rarely more than about 15%.

if you have 4ext recovery you can go to the wipe settings an click on "wipe battery stats" but your battery has to be fully loaded.
Thanks for the suggestions guys. I have done all of the above mentioned things but still getting very poor battery life. Are you guys using the Anker extended battery or stock?
i have the stock battery and i heard that the anker batteries are ****.
sometimes they just explode and i think the 200 mah more dont bring much more batterie life with it.

How long do you get on a full charge with stock battery? I actually just ordered an Anker =/ hope it's not ****...I'm running ARHD 6.5.4 with Bricked kernel 192 min with 1566 max using lagfree governor...battery life really leaves something to be desired...getting about 5 hours from 100% to 15% ...tried wiping batt stats and trying different profiles in SetCPU as well as underclocking. Any suggestions please throw them my way!!
Part of the problem IS because it is an Anker battery. I have heard many bad reviews about their batteries. Another issue is that most "extended" batteries really aren't any better than stock. A lot of times they are WORSE than stock batteries. If you tested the mA with a good digital meter I bet you would find between 1200-1400 on a full charge, with a supposedly 1900mAh battery. I hate to break it to everyone like this, but the only TRUE extended batteries you will find will be physically larger than stock. You can slap whatever damn label you want on a 1500mAh battery. Call it 3500mAh for all I care, you can't deny what it really is. A 1500mAh battery. You can't get more charge out of a battery unless it is physically larger that the original.
And I don't know about you guys, but I am skeptical about true extended batteries for the Sensation. The antenna contacts are on the battery cover! That means they would have to ship you a modified battery cover to fit the bigger battery. If they screw up one contact or don't put enough material on it from the factory, your sensation will be a signal-less paperweight.
Another thing I suggest is downloading BetterBatteryStats. If you have a bit of knowledge about how Android's OS works, you might be able to look at the Wakelocks section and see if something is preventing your device from entering Deep Sleep mode...the top four causes of battery drain are the screen, WiFi while on but not connected, GPS, and applications locking your device out of Deep Sleep.
Thanks for the reply. I am currently using the stock battery shipped with the phone. What do I check for in the app you mentioned to see if my phone is entering deep sleep?
I attached a screenshot of the wakelock section. Let me know if anything looks suspicious or if you need to see a different screen. Thanks!

Sorry, I tend to ramble on a bit
Best way to check would be to click the first drop down menu and look through Wakelocks and Kernel Wakelocks after your phone has been running for a bit. Start up the application for the first time, accept the changelog stuff, then close it out and lock your screen. 5-10 minutes later check that dropdown and see if anything says *Wakelock* by it. There should be a gauge under each item, it shows a percentage of time the process has been running since last boot, charge, or whatever option you pick in the second drop down menu. If any of the gauges are almost full or beyond 50%, there's the culprit.

Check my post above I posted 2 screens with kernel wakelocks from the dropdown and partial wakelocks...don't know what either means thank you for your help!
From that screenshot I don't see any major partial wakelocks. The HTC Facebook sync doesn't seem to be helping, but it isn't causing too much of a drain at the same time...try peeking through kernel wakelocks and see if anything stands out
Holy crap, CNT is what is doing it! The device has been running for a full hour and it has locked your device into Awake mode 100% of the time. I will do some research and see what role it plays.
Kernel wakelocks is just 100% to "No reference since charged yet"
I don't know what happened, but lately my battery has been about 20% less every day I come home from work. Right now it was down to 9% after only being on for 1d3h, I'm used to getting over 2 days easy on a single charge. I don't think I installed anything recently, and this is running CROMI 3.2.2 with I think the Clemsyn 1.3-1.8GHZ kernel. Any ideas to figure out what's causing the drain?

You need to install "betterbatterystats" to find out what's the issue. Any changes in the way you sync email, messages? any app with location service turn on by default?? well, best bet is use the app and find out.
I'll check it out. I didn't change any syncing, the only change I've made is I started using GoogleNow a little more, but I don't think it would make this much of a drastic difference.
Probably a rogue app, as buhohitr said. Reboot two times, install BBS, reboot again, and sniff it out. The reboot number doesn't matter that much, but I strongly advise to reboot in between to see if that solves the problem altogether. If not, BBS has your back.
Noticed last night that installing multiple launchers with 3.3 CROMi is eating more battery.
For instance GO is running while APEX is active.
Each on average are stealing about 3.3%
I do like the switchable launcher feature in 3.3 a lot however.
Never mind. I just noticed that you run custom rom.
I had that problem before I upgraded to 10.4.4.25. The standby battery life was a total nonsense. It would drain in less than 2 days without me even touching the tablet.
Now with 10.4.4.25 I am on 8 and half days and still have 33%. Although they seem to screw up battery stats app in settings.
Well, I installed the battery app, and looks like it was draining at about 1% per hour today while it was sitting idle. Not sure if that's good or not, I had it sitting in balanced mode all day. I do know that I started reading on it when it was at 54%, after about 30 minutes I stopped reading and it was at 50%. I went to bed, went to work, and when I came home it was at about 35%. That just seems like a lot to me.
Not sure if related since your on custom rom, but randomly my battery lasted up to about a day and a half with no use. Batterystatsplus said cell standby and maps was taking all of the power. Cell standby makes no sense and gps was turned off as well. I ended up resetting tab from the recovery menu because these rogue aps made zero sense. Back to 8 days of use.

Yep, Google Maps does that. To pretty much everyone.

I had this problem but with stock 4.2. I narrowed it down to two widgets I had placed on my home screen. BBC news and Appy Geek. I don't know which was was the culprit. Removing them solved my issue completely.
