I used this method to get a reading
-> download from Market 2 widgets, if you haven't already, they are CurrentWidget and Brightness Level by CurveFish http://curvefish.com/widgets/brightness-level.htm
..Both are well popular and free widgets...
->Put them on the same desktop.
-> Wait for the CPU to "settle down processing", about half a minute + have your phone resting on a steady surface.
-> Choose 0% brightness, wait 15 seconds and tap "update now" on CurrentWidget -> tap it once or twice more to make sure it registers the ~same value.
-> Repeat this for brightness of 25%, 50%, 75% and 100%.
After posting it please just name your Model number and what ROM, Kernel you are using. If u are feeling lazy, just do the 0 - 50 and 100% brightness measurements...
These are mine stats:
0% display brightness - 96mA
25 % display brightness - 110 mA
50% - 148mA
75% - 184mA
100% - 230mA
Phone is S510e, stock rom and stock kernel.
_______________________________________
The reason I am posting this is mainly because my "Battery status and level" reports stats like this: 15 hours of battery time since charge, 10 of which on standby, and 5 hours with me doing something with the phone on 30% screen brightness...Display consumption for this is 82% ..
And ofc, in my opinion, a very bad battery life due to this overall.
The more people do this the better, we will see what really is going on... If you have any other battery related stats or experiences, pls post here too..Thx!
P.S. CurrentWidget logs 11 to 14 mA in locked mode...
I'd also suggest that you also download and use BATTERY MONITOR WIDGET application as well as current widget, the two widgets do the same thing but I believe that BMW clocks very different (and in my opinion correct figures) which are slightly lower 5-8mA screen off compared to 10-12mA.
Can you tell me your stats Ben?

I believe that my system is configured for efficient for battery usage.
Auto Sync = OFF
Wi-Fi = ON
Mobile Data = OFF
These are my results using Battery Monitor Widget
I ignored the first reading after the brightness widget was operated and the level was changed so that the system had an opportunity to stabilize and then picked the next two readings, with a sample rate of 30secs apart.
% - mA
0% - 47/46 mA
25% - 62/61 mA
50% - 89/92 mA
75% - 97/98 mA
100% - 108/107 mA
Thanks

Thx Ben! Spread is pretty much equal from 0% to 100%. 100% wastes times 2.3 more amperage then 0% brghtnss..Crazy thing is that currentWidget shows douple the amperage in comparison to your widget . But I have read your threads on this subject and it seems that it is more correct...
Btw..I have also offed mobile and syncing and left wifi on during measuring.
CurrentWidget does seem to report twice the amps of Battery Monitor. I am not sure of the exact reason for that.
If you prefer current widget there is a setting that allows for a "Custom Operation" to be performed on the current value. I adjusted this setting so "operation type" is "divide" and "operation value" is "2", which gives me to get the same current numbers as the Battery Monitor Widget.

Those values are WAY too high! At 0% brightness mine sits at a comfortable 18-20mA (dependant on WiFi operation).
At 100% brightness, mine sits at 87mA (again, fluctuates 1 or 2 mA dependant on WiFi operation).

Yes and yes!
You guys aren't doing anything stupid like running a Live Wallpaper when testing, are you? I'm fairly sure you aren't, but I have to ask!
100+mA for 100% brightness on the display is frankly abysmal! I mean, my Motorola Xoom manages less than that (actually the Xoom eats far less power than any other Android device I've come across, by a HUGE margin... hence why I need only charge it once a week at most, even though it's powered on with WiFi running 24/7)
Yes, Sense is a battery hog! It's why my guide on maximum battery runtime explicity recommends ridding yourself of it entirely!
As bad as Sense 2 is on the stock ROM, Sense 3 is at least 25% worse (from my experience with several Sense 3 ROMs, anyway)!
Why don't mobile manufacturer's focus on what really matters: longevity of uninterrupted, AC-free (I.E. battery) runtime?
Phones have already reached the necessary performance mark! We don't need hex-core 9001GHz CPUs in phones... we need a phone that'll run for more than a day between recharges!
Hell, I'd happily accept the Desire S being TWICE the thickness, if it meant double the battery runtime!
If you're reading this HTC (which I severely doubt).... why not make a "Fatboy" range of your current mobile offerings? I'd buy a "HTC Desire F" or a "HTC Sensation F" if you could guarantee more than a day of runtime under typical bench conditions! I bet many others would too!

LOL, HTC fatboy....
no live wallpaper here, and every battery consuming option off...
As time progresses and the non Sense ROMs improve and become stable I do become more and more tempted to make the switch......
I tried this with CurrentWidget (divide by 2 option enabled). wifi on, data off, sync off. 30s apart readings like ben_pyett.
0 - 42/45
25 - 56/54
50 - 69/72
75 - 87/89
100 - 109/106
I have CM7.1 & Tiamat 1.1.2. I have also gone through LaKraven's battery minimisation how-to (except for any Tasker steps). I don't get numbers like him though. Maybe my stock radio is a contributing factor.
Should point out that my readings are taken in a GSM "notspot" (no mobile reception of any kind) and I'm running a modification to drastically increase the polling interval when the signal is unavailable.
This means that I get spikes on the GSM (which I ignore when taking measurements as I meter the GSM drain separately).
Even so, even with GSM on, I still think that 100+ mA for screen at 100% is higher than it's supposed to be! As I say, my Motorola Xoom doesn't even use 100mA for its 10.1" display at max bright (in fact, the Xoom's biggest battery drain is its CPU, followed closely by the WiFi radio)
EDIT: To match my measurement method, use Airplane Mode to cut out all the radios (leaving only the screen and CPU consumption to meter).
Right now, screen at 100% (button backlight off)... 87mA
Button backlight on... 106mA (there's the ambiguity!)

this method isn't possible as There is an issue on most roms certainly all sense ROMs where by air plane mode uses over five times the battery consumption than just leaving phone on, which is madness, but true

Let me put it this way...
Display switched off... GSM chip (no signal area) switched on = 47mA drain
Display switched off... Airplane mode = 2mA drain
Not sure why others are reporting that airplane mode is drawing more power... you using a custom Radio by any chance?

We'll I might be at the moment, but, that's certainly not the problem, as I've tried all of the RADIOs that we have available to us and the problem is always there, the air plane battery drain issue has been previously been noted in several threads and the conclusion drawn so far is that its either a STOCK kernel or a STOCK ROM issue....which is the reason why you don't get it I imagine!
Evidence like that certainly sway the balance of the scales in CM's favour!
EDIT: Just realized I've used a couple of custom kernels (MDJ & UNITY V2) and the problem still existed.
Any idea if your Kernel would function on my sense ROM? I don't think it would unfortunately.....just to test the theory....

I tried your kernel (which I know isn't built for Sense based ROMS) unfortunately it had some intermittent issues with wifi (in that wi-fi worked fine to start with then I just couldn't get any joy from it) I didn't do a full test but the phone signal seemed fine.
With your kernel (Tiamat_Saga-v1.1.2) rather than the HTC stock (build 1.48.707.1) Airplane Mode = 18mA which I appreciate isn't exactly great, but, it's less than half of what it normally consumes (38mA) on a Sense ROM.
I'm not quite sure what that proves, but it's progress at least!

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?
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
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...
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.

No the 3-6ma is from HD2 device,
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,,,

and performing battery calibration + 8+1+1 charge cycle.
What does dis mean? can you direct me to link to this.
I'm impress with your battery performance! - stock accu u mean kernel?

Check my sig, I'm using Darkforest 6.1.0. OC'd to 1.5 GHz on-demand, powersave on screen off. Auto-brightness. Right now I have 52% battery left after 17hrs moderate use today. Goes alright
