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...
Can someone please help me with my horrible battery life on my infuse? I cant make it a whole day on my phone. I don't play games on it at all during the day because I work. The only thing I do is make calls and text. I had 100% battery this morning at 6:00am and it is now 1:30pm and I am down to 12%. I am running the latest version of catyrom on my phone and it was supposed to increase the battery life. My phone is less than a year old (probably only 6 months old if that) so the battery on it should not be shot. Any help would be awesome!
THANKS!

Should not be like that. All the uckl2 base ROM have very good battery life.
Try a reflash. I would go into cwm, wipe data, wrote cache, wipe dalvik, fix permission, go to mount, wipe system, data and cache. Re flash ...i would try Another uckl2 base ROM then go back to caty if battery seems better
Buy Juicedefender Ultimate, set it up whichever way works for you. I couldn't tell you about Catyrom and the JD AOSP helper compatibility.
Buy and set up SetCPU to downclock your CPU when your screen is off, and when your phone's charge goes under a certain amount. Change your governor to conservative, ondemand, or smartass. Those will help. You could try undervolting, but be wary of doing it too much.
Look at your battery useage history and work out your app issues from there.
A faster microSD card wouldn't hurt, class 4, 6, or 10 would be better than a class 2, if you're even using a microSD card. Faster read/write means less time reading/writing.
If you need even more power, you could always go to 2G networks if Catyrom allows you to use them. From my experience, it will interfere with speakers on other devices. I have ~8 pairs of speakers in my office, and the interference drives all my co-workers nuts.
And you could always carry a spare battery, which isn't the best of options, but it's a sure fire way to go on
Reduce the number of widgets you use, reduce the number of screens you have, remove redundancy in your apps, and turn off live wallpapers.
Turn off auto brightness, and set it down to lowest valuable that is useable, then bump it up just a bit more. Then set your timeout to something conservative such as 15 or 30seconds or 1 minute.

Thanks! I downloaded juicedefender and setcpu both. I had seen juicedefender in the market but was a little questionable about what it does. but I will see what and how good it does tomorrow. I have my phone charging right now so I will upload a pic of my battery life tomorrow around 3 so we can see how my phone is doing. When I looked at the battery usage when I plugged in my phone it was on for 7h 34m 24s on battery and when I plugged it in I had 6% battery. I really hope that this works. like I said all I do is text and call during the day.
Thanks again!

JuiceDefender, to put it shortly, will kill your data connection/wifi/gps automatically and will enable them again on a schedule.
Those won't interfere with your texting or calling, but it will interfere slightly with your MMS. You'll have to wait for data to be re-enabled to download pictures/videos.
You can set up a schedule for work to be on a more frequent basis than the one when you're not at work, and once you set the battery threshold and the "ignore on low battery" function, it will stop all schedules once the battery reaches that point.
It will re-enable data/wifi when you turn your screen on so you can use it.
That's about most of what it does and it does work very well.
If you'd like, you can get cheap spare batteries from ebay. They mostly ship from China so they take up to a month to get to you, but they're very inexpensive. I just got my 2200 mAh battery (it fits just like the stock one) and it's not even broken in yet. It's 2 PM where I am and I unplugged my phone at ~8. I'm still above 65%. I don't tend to have very restricted battery use like some folks, but I do look for ways to reduce the battery waste. Most of my stuff works when the phone is in idle/deep sleep. I haven't done much of anything today with the exception of a very few calls and a few texts, a little surfing, and I downloaded a CM7 update from the CM7 port's thread.
When it's been broken in it should do better. CM7 isn't as battery friendly as some other ROMs but I like it very much so far. I have been furiously debating whether or not to move to Zeus ROM, as it seems like the big boy's Infuse ROM right now but I can't tuck away CM7 just yet
EDIT: Another, probably very minor, battery saver would be to download and install Adfree. It reroutes all outbound requests for advertisements to the device itself, so those don't download data and you don't see ads. Instead of them possibly keeping your scheduled data connection on for longer while they download (or pumping up your data useage), they never go outbound because they don't require internet access once checked against the HOSTS file.
Also don't forget to do what qkster advised. Bad flashes do happen, and you could have just had a bad flash.
Bassman--What does about phone say is eating the battery?
Sent from my SAMSUNG-SGH-I997 using XDA App
I have never gotten what I thought was decent battery life out of this phone... I work as a field tech so this phone is my office... Serendipity gave me the best battery life of any rom I've tried and I've tried several.
When I first got it I used Infused rom I would average 3 to 4 batteries a day. When I went GB roms that dropped drastically to 1-2... Serendipity would get me through the work day (8-10hrs) and home w/ a little to spare. Lately I have been bouncing back and forth between caty and zeus averaging 2+ batteries a day.
Might add I received my phone as a hand me down from someone at work. He only used it for a few weeks but kept it stock.
On any rooted ROM, i usually use tibu and delete buddy now, facebook, att, tether manager, devive update manager, etc..every possible background crap.
Every user is different, but with just calls and text, is not unusual for me to have 2-3 days before a charge.
Data sync and wifi off when not using data
Rxnelson the about phone says display. But that is the case on almost all phones. I have my auto off set to 1min

You can also try following basic methods:-
1. Turn Off: GPS, WiFi, Screen Rotation, Bluetooth, APN, Vibration, Animation etc.
2. Minimum Screen Brightness Settings
3. Minimum Screen Timeout setting.
4. Dont install Widgets based apps on home-screen
5. Kill the un-necessary background apps from Task Manager.
6. Use black theme in apps.
Thanks

Something I've found helps a lot is rebooting every morning. I'm running Zeus and noticed that the first day after a reboot I get great battery life (light- to medium-use would leave the battery at 50% after 12 hours). By the second or third day, I'd barely make it through the day. Since I've started rebooting every morning my battery life has been great. I also used BetterBatteryStats to help figure out which apps were keeping my phone awake. I learned that the Stocks app runs in the background waking the phone regardless of settings. Juice Defender is really a waste of time - you'll get better battery life by figuring out what's killing your battery and getting rid of it than having Juice Defender disable all of your phone's features when the screen is off(while using battery itself).
Man your battery life shouldn't be that bad. If it isn't a bad ROM flash then you could have a bad battery. Sometimes batteries die after a few months.
I did a lot of testing for apps and whatnot to try and see if I could maximize battery life. I tried all the juice defender and similar apps and didn't really like how they were killing off my services when the screen was off.
I found out that the main killers of my battery life were specific apps. When I used email apps with IMAP push services I noticed that they would kill my battery because they kept preventing my device from sleeping. I sometimes need about 18 hours in a day before I can charge so I really wanted to maxmize the battery as much as I could. I monitor new apps when I install them. Some seem sneaky so the battery stats might say that the app is only using something like 4% but it is also making the Android OS keep alive and use a higher percentage. I have about 70 apps installed but deleted most of the apps that seemed to kill my battery. In an 18 hour day now it is common for me to have at least 50% or more battery left over. It did take me a while to get this kind of battery life though. I was getting pretty frustrated for a while.
I'm running stock GB 2.3.3 (Rogers) and I am on the Bell network in the Great White North.
Background: I have had phone 11 months. I am very familiar with how the battery drain is while it is stock (WiFi ON all the time). battery lasted ~16h which is plenty for me.
Rooted phone, Battery Life on AR14 and IceColdSandwich (and others) was around 20h with WiFi on all the time and light use.
Recent Kernels (anything IceColdSandwich 3.0.0+ or AR 23+ (haven't tested between 14 and 23) cause a base of around 50mA of drain even when phone is locked. Battery life is ~8-10hours WITH NO USE. I have tried these ROMs without installing ANYTHING on them with the same results.
Current Widget does not identify an offending program from what I can tell.
WiFi off, the phone lasted 2d9hr of pretty light use.
I first started looking into WiFi when I forgot to turn off airdroid and unplugged the phone for 3 hours. I found AirDroid still running but could not connect to it via laptop or desktop until I tinkered with the phone a bit more and the WiFi connection cycled.
However during this time, the charge lost on the battery was a reasonable rate, and after the WiFi connection cycled it dropped like the usual rock.
What I've tried:
WiFix
WiFi polling interval increase
Cleaning/checking battery cover contacts
Changing battery covers
Battery Calibration (which is a myth from other reading I've done)
A couple of different programs like Juice Defender.
On the list to do:
Try a different Kernel
Root my friend's phone and trade him hardware (he says he never uses WiFi, so it won't be an issue for him)
/wrists
Thanks for all the suggestions and help so far. I understand that the problem is pretty obscure and seems rare.
on icecoldsandwich ive seen quite a few people show an improved battery draining using lordmods newer bfs kernel. maybe give that a try and report back?
http://forum.xda-developers.com/showthread.php?t=1450962
kernel: http://goo.gl/ZqBZl
btw, very good informative question. its heart warming usually we get 'my battery sucks yo, fix it!' haha
Here is some irony.
Exitz ICS AR25 has been on the phone for a couple of days and has lost essentially 10% per hour when not on the charger (been off work in my house) After the 4th day, I installed AirDroid and AngelCamera. I took it off the charger last night...
92% 6 hours later AND the phone has been awake(?) all night...
Seems I left AirDroid 'running' but couldn't connect to the phone through AirDroid until after the WiFi cycled...
I will see how the drain is today. I'll out of the house all day tomorrow (half a day in Denver), toggle off the wifi for a day at home, and then try your suggestion Darunion.
Here are a few screen shots (first two are old), and honestly, I don't know how much I trust the battery stats.
IceColdSandwich 2.0.0 pretty much shows that battery life I have been used to for a long time including before rooting. Not AMAZING, but not fail. (WTF Proximity Recaibrator 29% of Drain on a 16 hour day?) Also note this is about the same rate of drain I experienced with Existz AR14 last week. Light use and ~16-19 hours of battery life. Not amazing, but I can live with it.
IceColdSandwich 3.0.0 pretty much shows the battery life I have been getting with any ICS roms since.. well 3.0.0 was released. Oh and the voice call that is 37% of drain lasted less than 10 minutes.
Existz AR25 (someofthedrain.png) the steep drop was a 20 minute phone call...
And Finally Airdroidwtf.png is the same install three nights later (this morning) If I could get battery drain like THIS on a regular basis...
Anyway, I'll keep trying to isolate this down to the specific 'area' of the phone that is causing it....
Edit: and as for Darunion commenting about the information I've included... I'm a patient person, I don't want to be a drain on the community, and I have no issue trying to solve a ROM, APP, Radio, RIL, Or watever issue. I'm only posting because the issue isn't unique to a ROM but is unique to a time frame AND the issue is not solveable via Google or XDA search
Right now it is looking like the 'extra' drain on newer ROMs is directly related to the wireless being on*.
Right now the phone is at 1day 19 hours with 14% left and the wireless was only on for the first couple of hours this charge cycle.
I never thought there would be such a considerable difference between battery usage on any ROMs.
I'm going to continue looking around and trying to solve things, and I haven't quite made it to trying the Kernel, Darunion. It is on the list after I toggle WIFI on and off throughout a day.
*The rest of this post is just back-story I have ran the phone on stock for 11 months before rooting it and during that time, I got used to leaving the WIFI running all the time simply because the battery always lasted through my longer days and my-typical light-use. I'm near WIFI that my phone connects to about 80% of the time.
So after rooting, I had a little increase in battery life and I never changed this habbit, or more to the point, I was leaving WIFI on as to make it one less variable in drain while testing various ROMs and different build dates.

Yeah, I know this isn't a typical issue for most everyone, and am not implying so.
Likely it will end up being something very specific to the two WIFI networks I am at for 80% of the time OR something else that is very specific to my circumstances.

Have you, by chance, removed and reinstalled your back covers? I know it's unlikely, but since they contain the antennae, maybe they've come a little loos, resulting in higher imepedence connections.

I have not specifically toyed with the covers as part of trouble shooting. I will be sure that I look at them after my battery finishes charging on WIFI.
It does seem to be more a software difference, (I've casually be at this for the better part of 2 months) as I have seen expected performance when flashing back to a ROM I've used.
Thanks, I like being able to limit variables and this will be one I check before charging the phone again.
(What I'd really love to do is convince my brother or one of two friends who have the Inspire 4g to let me root their phones so I can trade them phones for a week and really isolate out hardware issues
fyi if you are still running icecoldsandwich. 6.2 just was released. Maybe give that a try?

Right now, I'd like to figure out WHY my WiFi is so bad on battery drain with later AOKP releases.
I'll try to rule out hardware issues (I'll look into antenna and MAYBE convince a friend to let me root their phone and trade them for a week... if not then covers at least.)
But likely this is something about newer releases and how my WIFI is setup. I don't live in a high-density area, so it's not because of too much wifi trafficz (I can barely see a 2nd wifi with any device and it's on the opposite end of the frequency choices.... by my settings)
Anyway, I am a very patient person, so I'll continue working on this slowly so that I can be thorough and find the real cause of the problem.
What I would wish is for someone to point me in the direction as to how WiFi MIGHT drain the battery so hard for later releases but not earlier. I'll be reading up more on logcat and how to read it in regards to wifi... but searching and reading is hard because 'wireless' and what not are very vague terms
Now at 1% (still) and 2d9h... is MORE than double my record on the first roms I tried after rooting OR my stock rom. and MORE than quadruple my record on any of the newer roms
I've swapped battery covers with a friend this past weekend, and the WiFi being on still drains the phone considerably (~8%/hr) when turned on. So if it's a hardware issue, it's not in the battery cover.
Wifi and blue tooth are very hard on the battery regardless. But 8% an hour seems pretty steep tho.
I would start by getting the current widget in Google market and put in on your home screen to monitor your Mili-volt ussage. If its running high like the 200+ constantly you have a lot of drain going on. When in sleep mode it should drop down to 0mv up to 8mv. If it stays high in the sleep mode you have apps waking your phone from sleeping. Which causes tremendous drain.
Next I'd try removing apps that have wifi permissions. To see if that drops your mv ussage.
Drop your notifications to less frequent times on your email and Facebook.
Remove any task managers or juice defender. They run constantly.
Google + is a massive battery drainer. Remove or limit notifications and sync as much as possible.
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.
Last but not least get a toggle button widget for wifi and turn it off when not using.
I'd you follow these steps this will drasticly decrease your battery drain.

Thanks for taking the time for this response!
I started by running current widget for about a week and with a 3 different roms AR23(?), IceColdSandwich 2.0.0, IceColdSandwich 3.0.0.
I was stock for 11 months, and ICS2.0.0 was a little better than battery drain than stock. AR23 and ICS3.0.0 were terrible and pretty much ran a constant 50ma drain asleep or awake as a baseline.
I'd really like to figure out what the difference is with the older AOKP and the newer AOKP, but that may never happen.
Next I'd try removing apps that have wifi permissions. To see if that drops your mv ussage.

I've been testing with stock roms since a couple weeks before I posted this thread. This is because current widget didn't really show any specific program causing the issue, so I wanted to make sure that I didn't have some issue from my installed programs.
The most I've installed (out of necessity is AirDroid and AngelCamera) in the past few weeks. Both were installed when I ran without wifi on one charge for 2d9hrs.
(I don't have a google+ account, I don't have juice defender or any task managers aside from the stock rom)
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.

This is likely going to have to be my solution. Just run cell data all the time unless I am doing something specific like downloading files or uploading pictures.
OR
Maybe I can convince my friend to let me trade him phones (root his and nand backup and then restore all his stuff to my phone) and see if it is about the same drain. His phone was bought a couple months after mine AND from a different vendor, so it isn't going to be out of the same manufacturer's lot.

I'm in the same boat you are. I'm running ics aospX ar-26 and I can barely get mine to last from 8 til 4. Wifi is pretty prevelent around here and I leave it on most of time. I guess I could try turning it off til I need it. Anyway I'll be following this thread.

You also might consider reading the threads on calibrating battery after flashing roms. I made the mistake of flashing a rom @ 40% battery. It jacked my stats all up. The new rom thought 40% battery was actually 100%. It had my stats all screwed up too. Except mine was Bluetooth. Showed running at 60% of battery ussage. So don't trust that system tool. Because the display is almost alway gonna be the biggest drain on the battery. An app called "spare parts" is a little more accurate.
I ran the gambit on this one finnally got my battery back to normal for me anyway. I've never seen a full days use with out charging. Get about 14 hours Max now. But the calibration steps is the way to go.

The new rom thought 40% battery was actually 100%. It had my stats all screwed up too. Except mine was Bluetooth. Showed running at 60% of battery ussage. So don't trust that system tool. Because the display is almost alway gonna be the biggest drain on the battery. An app called "spare parts" is a little more accurate.
I ran the gambit on this one finnally got my battery back to normal for me anyway. I've never seen a full days use with out charging. Get about 14 hours Max now. But the calibration steps is the way to go.

I actually have read quite a bit about battery calibration... and before I flashed a new ROM, I've made sure that current widget has been tracking 0ma for a while. (Only reliable way to be sure you have a full battery from what I can tell)
The batterystats.bin file and calibration has been ... contended in a number of places, mostly stating that when taken off the charger 'full' the battery stats file is overwritten... which makes calibration a non-issue (assuming that you occasionally charge your phone for a while after it hits 100% from time to time)
The problem is that the WiFi mA draw is HUGE compared to what it should be (in theory from reading other people's logs), and it's not because of the battery cover. AND It's not as bad in older AOKP ROMs than it is in newer ones. SO it could be a hardware issue exacerbated by a change in how WiFi is handled, but the hardware issue was never noticed because the battery life Stock was sufficient for my needs.
I've been busy working so I haven't been able to continue troubleshooting the phone (damn my patience), but Mondayish, I'll likely have traded my phone with a friend and root it and flash a new rom and see how the drain is with completely different hardware from a different vendor from a different lot of phones.
I had a similar issue with wifi. I changed the build.props wifi supliment scan from every 15 seconds to 180 and used the wifi fix manager apk. That seemed to help. Coupled with a proper battery calibration and I'm back to my display being the major battery draw.
So don't know if that helps but it seemed to work out my bugs.

This I can do right now.. and given I'm on the same, unmodified AR24 release, I can observe it for the weekend before I annoy my friend about his phone.
Seems the WiFi scan interval was already set to 100... moved it to 180 anyway.
I used to have this issue. I could literally see my battery draining while I was using it. I keep wifi on most of the time. I recently purchased an anker battery online. It is AMAZING! My old battery wouldn't last more than 6 hours or so. Right now I'm at about 14 hours on this charge, and I'm at 47 percent. Try swapping his battery for yours for a day or two. Another thing to try is different radios if you're losing power to cell standby.

The phone ran for 2days 9hours with WiFi off and lasts for 8-10 hours with WiFi on. I am pretty sure that it's not a Radio/RIL or a Battery capacity issue. ;(
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"
Hello, XDA-Community.
I bought my HTC Sensation XE 3 month ago.
First i must say, the Beats-headset has a very good sound, but it's bad quality.
2 weeks ago, the right headphone stopped working. I gave it back to Media Markt and they sent it back to HTC, i must wait for it-.-
but now the real problem:
i always have got a bad battery life! (lock at the attetchments)
i tried nearly all roms(really a lot), all kernels, i tried to underclock or undervolt an different govenors. i even bought an anker extended battery but it all didnt't changed anything.
after that, i tried to downgrade form fw 3.33 to 3.32 and to downgrade the hboot, but nothing.
does anyone of you have this problem too or can anybody help me?!
its so bad, i even cant get 10 hours with it..
2h and 33 min screen on time an still 9 percent of battery.
Based on your screen on time, that battery life isn't insanely bad. It's not good, but it's not utterly terrible.
Have you tried the simple stuff like lower brightness? Turning BT and GPS off when not in use? Keeping Mobile data turned off? Lower the screen time out to 15 or 30 seconds?
Those things will do wonders for battery life.
Also make sure you're not overclocking with a performance governor on your kernel. That'll burn battery like crazy. Use a more battery friendly governor with your kernels like Badass or even Conservative. And don't clock it up to 1.7 or anything nutty.

i never use bt or gps. only thing is mobile data.
screen is nearly always on lowest and if not, its auto.
time out is at 45 sec.
if i use bricked kernel, my battery life is better, but every hour my phone reboots less one time.
now i am on faux kernel, underclocked to 1.1 ghz and undervolted to -75. the govenor is intellidemand.
You could try to use a non-sense-based rom like cyanogenmod, for me there was a huge improvement.
Regarding your Problems with random reboots on bricked kernel, just set the minfreq to 384Mhz and it should be alright

both problems(battery and reboot) are still there after trying this...
How much gaming are you doing? Regardless of how much screen on time you have, games can drain the battery like crazy. What's your usage pattern like? Lots of web surfing over mobile internet? Watch a lot of movies? Games? 2.5 hours of screen on time isn't too bad, but it's not great either.
If all else fails, wipe all except SD card, install ROM, restore apps without data unless that data is extremely important to you. Also make sure your radio and RIL match with something like GetRIL. Match your firmware to your ROM base too (ie. 3.33 firmware for 3.33.xxx.xxx ROM).
Have you tried to put the phone in airplane mode during the night time. Or reset your battery stats?
2.5 hrs of screen on time isn't bad when you also had an additional 6.5 hrs of standby. But the biggest thing you can change to save battery is background data and auto sync. Turn those off and expect big difference. Also don't use auto brightness unless you have to. If your inside then turn it all the way down .

REMEMBER TO HIT THANKS IF I HELPED YOU IN ANY WAY, IT'S POLITE AND APPRECIATED.
Hi there, I had absolutely awful battery life on my stock battery! I understand completely what your going through. I did however find a solution . First let me say I've tried just about everything, turning down brightness , turning off sync, switching kernels, turning off gmail, yet still the battery life was awful! So finally I purchased a extended life battery, I choose Anker because the price was low. It did help but I still was not where I wanted to be. Then I decided to purchase a mugen 3500mah battery. It's expensive but worth every penny! Now with heavy use I'm on 100% for two hours. I can use my device heavily for 19, hours and still have 42% battery left ! It's amazing! I wish I got it sooner! It does come with a replacement back cover to fit the battery but my 4g signal is still strong, WiFi works perfectly , navigation works perfectly so no worries about the case interfering with signals. It does make the phone thicker but it still fits in pocket, and feels good in your hand . It does look thicker but who cares with this kind of battery life! Finally I don't have to worry about my battery! If your tired of worrying about battery life then get the mugen 3500mah battery. Buy it directly from mugen because there are too many counterfeit batteries going around on other sites. The downside is it costs 100 dollars but honestly its worth every penny. If your serious about getting a great battery then this is the one. I don't regret getting mine for a second! It makes all the difference in the world! I had to save up to get it but it was worth it. This battery will solve your issues! It solved mine ! Best wishes and hope this helps you.

I'd recommend that you don't delete the battery stats. The phone should learn over time and every time you delete them it has to start from scratch again.
but how to calibrate the new battery?
still having so bad battery life, after disabling auto-sync.
You calibrate battery by draining almost down to about 10% then recharge to 100% repeat this process about 4 times and battery will be calibrated. I read your not supposed to drain to zero although some people do during calibration. That's up to you. I read draining to zero can sometimes put the battery into a deep sleep and its very difficult when that happens to get it awake again. So I only go down to 10%. Hope this helps and answers your question.

As I understand it the phone/ROM won't allow the battery to be discharged fully to the state that it'd cause a total battery failure. Get CurrentWidget from the Play Store.
I can't remember the Full/Discharge voltages (~4.2V to ~3.5V) but not certain.
Just let the phone charge fully and discharge normally (let it get to a total turn off) a few times and you'll be fine. Please stop wiping the battery stats it just confuses things.
