I have an unlocked T-Mobile Sensation 4G and I've tried a lot of different rom (with Sense and AOSP, GB and ICS).
I had made battery calibration every rom change (Full charge -> wipe battery stats -> do some full discharge/charge circles in normal use).
Every time I have 50-100 mA battery drain in "sleep" according to Current Widget and another battery widget (tried another to commit that Current Widget tells truth).
The phone settings are maximum power-saving:
Fixed small brightness
2g only
Data and auto-sync are turned off
Wifi only if needed
CPU is downclocked to 1.2 gHz
Battery is stock. Phone is two months old.
In my regular usage (1 hours of calls, 10 min wifi) phone dies in 12 hours after full charge.
It is not my first android and I'm not a total noob. My Desire HD with one year old battery live 2 days with my usage.
Also I notice, that sometimes battery left is not accurate and changed after reboot to a bigger value. For example, 80% left -> reboot -> 82% left.
Any suggestion?
Thanks in advance!
Sorry for my poor English...
My suggestions:
1. Use system tuner or a similar app to check up on which apps are draining the most power (keeping the CPU on, etc).
2. If no culprit can be found, full wipe and reflash your ROM, and refrain from downloading any apps, see if that improves battery drain. If it does, slowly install more apps until the battery drain goes up again, and you'll know whats causing it.
3. If reflashing does not help batter life, you might want to try another ROM or kernel.
4. If none of those help, or even if they do, I highly recommend an ANKER battery, it'll at the very least boost your battery life a few more hours.
5. If the battery life still sucks, then it might be a hardware issue and you might want to get it exchanged or whatnot.
I used to have the same high battery drain problem, but after flashing new ROMS/Kernels and switching to an ANKER Battery, I now get 2 days of light/medium use out of my Sensation.
Currently using Insert Coin 4.5.0 with 1.5GHz overclock+undervolt if you're interested in trying.

Thank you, I will try.
How much does your battery actually drain overnight? Should be around 1% per hour or less if all is well. Disregard currentwidget in deep sleep mode as the Sensation has a very broken meter.

I'll check it this night.
With jumping battery meter I don't know if these values will be correct. But when the battery value reaches 0% the phone shuts down immediately and don't turn on. So 0% it counts well.
i think im also having the same issue . i checked current usage when in sleep mode.its between 50-80

12hrs with the standard battery is actually very good for a sense build, without sense it should go around 15 - if the battery is in good condition. The battery driver for the sensation is very buggy and you won't get accurate results with any measurement app. Don't worry about the standby or inuse readings as they will both be wrong.
If you're battery drains faster than 1% per hour in standby, assuming you are in a good signal area, then use a system info app to see which program isn't sleeping, then uninstall that program.
But it doesn't sound to me like you have a problem.
According to the log file it drains 1-2% in hour (now I'm using aosp build, MIUI). I think, new Anker battery is the only way. Thanks to all!
Maybe in the future we'll get a more accurate battery driver...

I am loving this rom, but also having HORRID battery life, I am literally dropping 10% every 90 minutes with an extended battery.
27% Cell Standbye
26% Bluetooth
19% Display
Now I keep reading that these might be false readings, but I keep reading this as a response to those having **** for battery life... so maybe they are not false?
Anyone having good battery life show readings like this? Those with bad battery life, what are your readings?
I'm running the CM7 w/the 2.5 radio - I'm in a 100% full time 4G area, but seem to have worse battery life when the 4G radio is on, so I just keep the phone on 3G - if I need the faster data I can always turn it on and off.
I'm running the stock kernal, no overclocking or setcpu type stuff going on.
Would like to hear from folks running this ROM w/killer battery life, what are your settings, tweaks, etc. Please specify if you're running an MR1 or Mr2/2.5 version and/or running the latest OTA 2 radio that just came out like yesterday.
I just turned off my FB sync (I forgot about that). I don't have gmail set up to sync automatically either.
I'm going to do this procedure a little later today and see if it helps, this is for the EVO, but, ya know....
34. "Calibrate" battery - (1) Turn device ON, charge it for 8 hours (or until LED turns green), (2) unplug and turn it OFF, plug it back in and charge for 1 hour (or until LED turns green), (3) unplug and turn it ON, wait 2 minutes, turn it OFF, plug it back in, and charge for 1 hour (or until LED turns green), (4) unplug it, turn it ON, and use normally.
Anybody else try this?
today will be my first full day of work use w/this ROM so we'll see what happens.
Best to keep 4g off if not using it. Also, turn Bluetooth off when not in use.

i had horrible battery life the first day - then it got better. then i flashed mr2 official and battery life is really solid. getting like 15-20 hrs with 4g always on, bluetooth on sometimes. one important thing is having a custom lighting table which i will post later.

I have never, nor do I intend to ever do this. I got an extended battery for a reason. I can go all day and then some on the official roms, and all of the Sense roms.
I am not new to CM7, I have run it on both an Eris, and an Incredible. Both devices got FAR better battery life on CM7.
I am not complaining about this rom, or Slayhers hard work. I simply want to gather information so that we may help him trouble shoot.

This is exactly what I did lol, I had lost 10% in the first 90 minutes, now I am at 58% at 5 hours. I have been streaming google music for 2 hours of that 5 though. I would guess I should have seen an increase in battery usage, but have not.
The battery readings are wrong, I get a full day on 4G with my stock battery and see those numbers for cell standby etc. I use lean kernel though
Sent from my ThunderBolt using XDA Premium App
do you see those numbers for BLUE TOOTH though? We know good and well some numbers are fake, but that does not mean all.
FYI I am now at 37% and 7 hours and 7 minutes... I have not used google music since the last post and I am seeing the exact same battery drain as when I was using it.
I have absolutely horrible battery life when I'm at work (which is basically a bunker). On a normal day, my battery will be dead within 6 hours just sitting there on my desk.
However, when I am at home (great 4G signal), I see my device getting upwards of 16 hours with moderate use.
I will also say that since I upgraded to the most recent radio, I have been having much better battery life at home. Additionally, my phone has stayed much cooler with the most recent RC + new radio combination.
I heard if you change the render fx to n1 calibrated, then you will get like 1 hour extra of battery life. You can change the render fx by going to cyanogenmod settings.
11h32m11s on extended battery 69% left
The other numbers have to be wrong. Theres no way cell standby is the number one battery user.
my cell standby is also showing 30% with the new OTA 2 radio.
I switched to dream kernel (have not wiped battery stats) and am now at 88% after two hours, that puts me at 6% per hour verses yesterdays 10.

only works for AMOLED screens.
edit: to be clear, it only saves battery on AMOLED.
so what i have found is that after installing dream kernel and messing with the governor settings... along with being connected to wifi. my battery life has improved tremendously. i wiped battery stats this morning after a full charge and didnt notice any change.. then i flashed the kernel and messed with gov. settings... after rebooting ive noticed a huge huge difference.. just my 2 cents for anyone who had battery issues like me
Yesterday I was able to choke out 20 hours while in a 4G area the entire time.
Running RC 1.2, Imoseyon's leanKernel extreme mode (extremely undervolted and OCd to 1.4GHz) and using the InteractiveX governor.
Also, I just happened to reboot and surprisingly it only took away 1% of my battery. Amazing considering whenever I did that on a Sense ROM, I'd experience a battery loss ranging from 7%-10%.

What settings did you land on as best?
cpu is set max to 368 mhz(very low) but i can crank it up if im doing somethign like playing games or downloading and want speed. brightness is at about 15-20 percent. the dream kernel and mr2.0 radio have made a big diff too. the dream kernel made the biggest. usually when id power off or reboot id lose 6-10 percent same as someone else i saw post. now i lose maybe 1 percent which is a huuuuge difference considering you lose 10 percent just because you reboot. also i try to stay on wifi wherever i go. on 3g i def notice it drain quicker, but i am no expert and there are a lot of people on here who by far outexperience and outknowledge me(my new 2 words) so im sure other people have some suggestions

My previous phone has been a Desire HD. Battery usage on this device while the screen was turned off has always been around 1-5 mA
On the Sensation batery usage while the screen is turned off is around 130-200 mA
I've tried various ROMs including stock.
Is everybody experiencing the same battery drain or/and can anyone explain the huge difference between these 2 devices?
the same numbers also here( 130-200 mA) i guess this numbers are not real because in 6-7 hours of standby the battery is emty... anyway htc sensation have the worst battery i ever had...maybe we get some good results with another rom battery friendly
My HTC Sensation's battery drains to 50%-40% in 9hr-10hr - with minimum use. All sync is turned of except weather and exchange account which set up to sync every 2hr - 3hr on weekends. Which is not bad comparing to SGS2, where i experienced terrible battery life 8hr max, but terrible compared to my HTC Incredible S, running with same settings i did see 2 days battery drain on one charge. I will put Sensation on proper test tomorrow, when i start my work.
Thanks for the quick replies
I'm just curious where the difference between 1-5 mA and 130-200 mA comes from?
I understand that the Sensation has a different feature set but this standby usage is outrageous..

Is this mA calculated by an app? It's well known that mA readings on the HTC Sensation with, e.g. Battery Monitor Widget, don't work. It's an archived thread somewhere on XDA forums.
Better way to measure it is this:
Leave your phone on sleep (screen off) for 2 hours or so (make sure the phone is actually in sleep mode!! If you don't know what that means, look for a thread on BetterBatteryStats as that could be your problem).
Then, find out how much of your battery drained at this time (make sure you didn't start the experiment at 100% because % battery is displayed extremely incorrectly between about 100% and 95%).
Finally, divide your battery capacity (1580mAh for stock) by the amount of hours the device was asleep by and then multiply the result by the % battery drained in that time.
E.g. phone asleep for 2 hours, 5% battery drained.
Average mA = (1580/2)*0.05 = 40mA
I dont experience any of the same battery issues... not that i know my mA draw.. but im going to start looking into. I can make my phone last easily a full 24 hour period with average use id say... But i froze all useless clutter apps no carrier or useless apps just what i use. I keep mostly everything off cept data randomly when im on irc/aim etc
Last charge 1d 10h and battery was at 49% :|
33% display
22% wifi
22% cell standby
20% phone idle
3% voice calls
Now didnt use phone very much in that 1d 10h though
found alot of useful information on this thread when it came to freezing apps i know there are a few tools in the development forum that will remove a bunch for you but i didnt like that method since i used some :|

Still strange that this battery seems to drains so much faster then my DHD although it should hold about 300 mAh more.
Why strange? Dhd has only one processor core and smaller screen resolution which should take less power to render, in theory at least.

The screen resolution should not matter in standby/sleep I suppose.
To be clear; I'm only talking about standby/sleep power consumption.
For the dualcore I would expect it to be around 10-20 mA compared to 1-5 mA. Not 130-200 mA..
Battery is atrocious no matter what radio, rom, settings whatever. Stick kernel, custom kernel everything. Straight up **** battery life on those device. Of course tour battery will last longer if you don't use it at all. But who got the sensation to just leave it I'm your pocket?!?

What kind of battery life are you talking about?
E.g. anything over 4-5 hours of screen on time is quite good. On standby anything over 24 hours is very good.
Hi, I have just come over from the HD2 threads as I'm using a Sensation XE now . My battery current when running android on standby was around 7 - 20 ma. On my XE it is between 180 and 220ma. I killed all running tasks etc but still no change. i'm using Battery Monitor Widget to check the currents. The only thing i have on is mobile internet. I also have on background sync but that was on with my HD2 as well. Is there anything I should look out for that my being draining the battery? Also I'm on stock rom
What did you already tried to solve the problem? Did you already do a soft reset/wipe all data (except that on the SD card)? How long is your battery life?
Yesterday i called HTC because my battery life is reduced drastically compared to a few weeks ago. They told me to turn off everything like bluetooth, wifi etc (after a soft reset) and put the phone in plane mode while screen brightness was 100% and screen time out never so the screen stays on during the test. Next I needed to write down how fast the battery was drained. My battery was at 55% after 2 hours (without doing anything with the phone). According to HTC this was to fast and therefore they send me a new battery.

In 1 hour of standby the battery has drained 5%. the battery current usage is way to high for standby. I have had this phone on 3 days so I dont think i need to do a full wipe. I dont use wifi or bluetooth and they are always switched off. Seems strange to have a high battery usage while in standby compared to my hd2. This battery is meant to be a high capicity
use battery monitor widget (use a beta version from the forum, not the market). set it to "mA corrections" and choose automatic from the list of supported phones. i get anywhere from 5-7 mA drain (standby, of course).

Hi, I'm on stock Rom too. Once I kill all tasks by the default task manager, it ranges between 25 - 60. It does take a bit of time to get there. I Have seen it as low as 19. You need to follow steps and get the beta widget and set it to corrections as mentioned earlier in the posts.

Check out guide in my singature.. It will solve your battery problems in no worires
Just a quick update. I let my battery completely die (never done this before) and charged my phone fully. I then deleted the battery stats.txt and switched phone off. the charged some more. Now when my phone uses -5 on standby which it never did before.
Well took my phone off charge at 11.05 today and its been on standby. It's now 15.52 and battery is still on F. Battery drain is now at -3 so i'm well happy.
Thanks indie. Can you let us know what will be happening in the future with your battery?
During sleep mode or the screen off I have a 54mA drain this is too far from my Android ROM HD2 it only has 3-6mA drain. I have the latest firmware 3.32, AOSP nonsense. I worried this drain to much even with cpu underclocked to 916Mhz, Minimal Rom.
I used Battery Monitor with graphical history.
Just my own experience, but I haven't really heard of a sensation owner getting 3-5 mA battery drain. The lowest mine generally gets is in the 40s and 50s. I'm more than willing to be corrected on this however, if other sensation owners are getting significantly lower battery drain then I am definitely interested to hear about it
When my sensation was still stock it wouldn't even get below triple figures and the battery life was woeful. Since rooting and so forth I'm seeing the 40-50 mA I mentioned before. With moderate use I'd get about 36 hrs out of a charge.
Maybe have a read of this if you want to look into it? It is a Desire thread, but that makes no difference to the process being used.
Ignore the reported mA values, the battery driver doesn't report them so your widget/app has to interpret what it can best guess. Even the percentage remaining is only an approximate value. Standby times will vary depending on how much time the phone is awake but after going from 100% to 10% you should get around 5hrs 'screen time on' with a senseless ROM and stock battery - 3 or 4hrs with a sense ROM. If you are getting less than this you may have a signal issue or a rogue app, otherwise don't worry about the mA values.
I came from the HD2 also, I spent a while trying to replicate it's standby consumptions on the sensation - I've now uninstalled all the battery monitors as they were useless on this phone.
I am using CurrentWidget and i get drain like 10 mA in sleep.
Also mine active use time of Sensation XE (stock accu) with insert coin 5.1.4 rom is more then 24 hours right now (after removing all unused by me services, and performing battery calibration + 8+1+1 charge cycle) + I always charge it for hour or two after it is showing 100%. So basically i unplug it @ morning ~ 6 AM, listen music for hour +, then all the day wifi + twitter + facebook + icq are active + some phonetalks, may be some photo\vid recording, reading e-mails and etc + hour of music on way back home, and after all that when i come home @ evening I usually have 60 - 50% left. No games are played, they are the only thing that can drain fast.
All i did - spent few days reading forums and internets about battery use, then selected all that made common sense and did it. Now I am very happy with mine phone performance. (also quattro gives mine device ~2800 score in benchmark). And active use time feels for me like 3x or even 4x of what I experienced on a stock system when I bought phone.

WOW 36hrs thats too good what ROM version you are using Mine with Virtous no sense last only 16-20 hrs with 2-3hrs wifi, 3.5 hrs screen on time with lowest brightness.. I also maximize the cpu for battery eg. lower down the frequency to 800-1000, samplling rate, treshold etc,,,

Perhaps you should calibrate your battery with an app like battery calibration
"It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break."
Make it twice or three time then you should see a difference.

The difference seen is purely down to the full charge cycles done in this method, after about 5 days the battery stabilized anyway, thanks anyway

CM10 battery life is pretty poor, anyone found a solution? I remember on defy someone improved by using stock battd folder in place of the original one, however desire s doesn't have this folder. Undervolted, full charge cycle, disabled auto brightness light to moderate use and only 8 hours. Display is main culprit according to system, maybe its getting too much voltage or something? I'm no dev its just a thought

I have the same issue on Pacman (CM 10).
My - I hope temporary - solution is to disable 3G as much as I can. For everyday usage, 2G (Edge) is sufficient for me. At home I am on wifi anyway, so I perform the heavy tasks then.
I noticed a very big difference when using 2G only vs. mode "3G preferred". It seems that there is a 3G battery draining issue with CM.
3g is known to drain battery. Keep it at 2g for better battery life.

I know this trick from the defy forums, cm10 had the same issue on that phone, I'm getting the best battery life with cm10.1 build 12 with andromod kernel, using ondemandx governer gives normal -ish life even with 3g enabled
