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

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

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

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

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

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

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

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

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

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

Personally, I believe that most of the time the procedure does nothing. I think there are times, though, that corrupt data gets into the battery stats. For instance, I had an app lock up my phone and force a hard boot. When the phone came back up, it showed 22% more battery than it had previously. I believe that bad data such as this can over time affect how Android reads your battery life. In that instance, I believe clearing battery stats would help. I don't think doing it just because a new ROM was flashed actually does anything, though.
Of late, I have been having heavy drain of battery on my Atrix 2. I am running JB 4.1.2 (672.300.404.ME865.Retail.en.05). Trying to troubleshoot it (including recalibration) since the last few days without luck.
The symptoms...
- Sudden shut down - Have had 50%+ charge levels. Goes down to 5% and shuts down within minutes. (You can see the random drops in the charge levels in the pic)
- Completely drained out battery charges from above 40% when plugged in & charges to 100% in no time. (that 67% charge in the attachment is within 5 mimutes of power plug in)
Does the battery need a replacement?

Try changing battery... even i had same problem with Custom rom. Battery used to last only for 10 to 12 hours but now its more than 17 hours on JB 4.1.2 leak,,,,...Use stock rom. and remove any unncessesary apps and installl ROM again if u want :good:
How old is your Atrix 2? If over a year then battery surely begins to give lesser performance. Disable any other task killer / memory manager & just let OS do its thing. See if installing Media Scan disable from play helps & do not keep using random chargers, make use of original charger as received with phone. Finally see Better Battery Stats. It is said battery stats should never be wiped but see if it helps you and finally search for Apex's better battery life guide for many handy tips.
I disabled notifications, sync, froze higher wakelock apps & my battery life improved a bit but then it is no fun existing in a bare bones environment.

The phone is just about a year and half old. The drop in battery performance is just too drastic, sometimes it doesn't even last an hour after the charge. Will try to go back to original ROM and see if it improves else will probably have to go for a new battery pack.

Look like a battery problem to me its not the ROM but anyways turn off location services and wifi they are a big battery drainer
Use 2G when u dont need high speed.......
Try this app called Greenify https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
(it helps to reduce wakelocks and improves your battery life)
:laugh: Let me know if it helped (btw chck your battery and see if its defected they are amny ways to chck it read up the forums )
i have the same problem whit any rom of 4.2. when the custom rom shows 5% i change to stock ics rom an that show me 45%

I couldn't write to developer's forum so I'm asking here.
I've recently firmwared my AT&T A2 CM 10.1.3 and battery drains really fast! The previous build was CM 10.1 (25th of June). I wiped cache and dalvik cache and firmwared CM 10.1.3. At least 3 people report that thie batteries on this ROM drain slow.
What did I do wrong???

Battery life varies so much from user to user that it is impossible to answer your question without A LOT more information.

Download the app and follow the directions in the op. That and reading through that thread itself should tell you everything you need to know about what is using up your battery.
That being said, everyone has different habits and expectations when it comes to their battery. What one person says is good battery life, another will likely say is bad. So just keep in mind that there is not a right or wrong, just what is right or wrong for you.
If I had a dollar for every time I said that, I'd be making money in a very weird way.
Thank you fro your answer. When I used previous version of CM the battery lasted 3 days with minimal using and turning the flight mode at night on.
As long as I installed newer version with JBX kernel the battery lasts 20 hrs max.
Power Tutor says that the most hungry apps are Android System and Kernel
My 1 month old s6 (920i) struggles to get a 3.5hr SOT during the day. Coming from the s3 where i used to easily get a 5hr SOT with the same usage style i can say this is pathetic. In the battery section top of the list i have Android OS and Google Services, followed by Facebook and Instagram. All drain battery more than the screen itself !!?
Note that i have most of the things turned off except when using them, such as wifi, gps, nfc etc...
Also i tried booting to stock recovery and clearing cache but this has not solved the issue.
The phone does go to deep sleep as i have checked using BBS.
What could be the issue any help or tips is greatly appreciated.
3.5 hours of battery life for continous heavy use is just about average. I get the same battery usage times.
