Horrendous Battery Life

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"

almost 70% deep sleep / 30 % awake when screen off

so I was wondering why I have terrible battery life on my phone not the worse it could be but my phone is being awake while the screen is off way too much. I'm using betterbattery stats app can someone please pinpoint the app that is causing my issue? see attached images also 3rd image is kernel wake locks im using latest synergy build with imoseyons kernel and ive tried trinity kernel and ive had this problem in stock what is causing so much kernel wake locks???as you can see 6 hours of phone time only 6 minutes of screen time and I drop 27% battery is that bad? i know standby time use to be way better with my droid one but what is average wakelock for most peeps?

See how your top 3 partial wakelocks are related to alarms? Particularly the AlarmReciever. Something is regularly telling your phone to wake up at a specific time. You'll need to check/post a screenshot of the Alarms list. It could be any number of things such as apps syncing or Google Now gathering information in the background. Get that other screenshot up and I'll try to help more.

Need dev help trying to boost MIUI/HebMIUI battery life

Hi guys and gals (if exist)
I really love my HebMIUI ROM based on Erikmm's latest MIUI V4.
I injected it the latest Team Acid kernel and auto brightness mod and it seem to work flawlessly,
Problem is battery life is just not good enough to serve as a daily driver.
I intend to merge PIMP my ROM mod and DS's A.I when I have time, but I seem to miss something.
I'd be happy to get suggestions.
Here are some XDA version Better Battery Stats raw data snaps : (10x!)

Idk but actually, when I told u my battery was not good and I meant it just could last for a day lol...and I have never used it for more than a day w/o a charge even on GB so i dont think its bad...anw, just try all things u think its good cause its hard to say anything bout tweaks and battery life I think cause...IMO and from what I have been through, scripts and build.prop lines not really help much both performance or battery life...and even OC or UV

I use cMiui 2.8.10.
so I don't know about HebMIUI but i use that rom around 20hr w/o charging.
This rom base on Hefe kernel 0.8(I think)
I tested Hefe 0.8.1 kernel but 0.8 is better than 0.8.1 battery life.
I use cMiui 2.8.10. I think cMiui and Miui is almost same.
I love this rom. I waiting UPDATE. ^^
You can try this and flash rom again.

Hi Dao
I know what you mean..
we both are more than heavy users, not leaving the phone for a minute, so in that way, yes, even on Valhalla I barely made it through the day.
Here I get this issue even if I have no activity and that's what bugs me. Batt is draining no matter what the user does. That's why I shared this technical data presented in the pics.
Thanks MJMJ
I'm not looking for a replacement.
I love the original MIUI, tune and customize it and share it, here on xda, especially for Hebrew speakers, but not only.
Every ROM has his pros and cons. Cmiui is based on cm9 and miui is based on touchwiz. I prefer Miui as it is the original ROM and is generally considered more stable.
I might try Hefe kernel though.
I think problem is related to device awake status...

That your phone is running quite a bit at 100 MHz when I might expect that it be in deep sleep caught my eye. I suspect something is keeping your phone from deep sleep. I can't tell from the BBS you have posted as I'm not sure what you were doing during the time it was collecting stats. I find the BBS from when I'm not touching my phone and it is running on battery overnight perhaps the most valuable.
As far as Hefe 0.8.0 vs. 0.8.1 on battery life, you've completely fooled yourself if you believe you are finding a difference. Go ahead and pull a source diff -- it all is about the interface to sysfs so that external apps can control the UV/OC, not the kernel operation.

I an not a professional. I'm just user of this forum.
I found this about battery life.
about WIFI I advanced setup Keep Wi-Fi during sleep -> Only when pluggged in.
use both of this hefe 0.8 and 0.8.1.
0.8 is wifi off when phone lock.
but 0.8.1 is not.
and battery life is different.
I write just my experience on my larrow professional konwledge.
I'm sorry I can not understand about source code,Interface and UV/OC.
Just experience.
Anyway I love cMiui and Hefe kernel.

Hi
I put WiFi as always on (even on sleep) because I wanted to get whatsapp and work mail in real time. Otherwise I didn't get them in time. Perhaps this is it. I will try it as on only when connected and report.
I would also try it with and without auto brightness mod. Let me know what data do you need.

What follows is my opinion and it is not completely backed up by experimental evidence, so take it as you will.
I don't believe that any ROM or kernel can significantly improve battery life over any other "good" ROM or kernel. I do believe that there are ROMs and kernels out there than can significantly reduce battery life though.
In my opinion, the two biggest factors on battery life (past battery againg) are
How you use your phone
The applications you or the ROM have running
The most insight I have gained on battery life is running BetterBatteryStats on a "full" battery (unplugged) overnight, when I'm not interacting with the phone at all. As soon as you wake up, turn on the phone, go to BBS, and save a full log.
With a good ROM/kernel, I think you should be getting 90-95% "deep sleep" and no more than ~2% per hour (on a typical 1800-2300 mAh "advertised" capacity battery in good condition) drain. If you're not getting that, I'd look carefully at what is keeping your phone awake. If you have questions about interpreting the results, I know the BBS author and has a great thread where you can post your logs and get some feedback.
When the phone is running, it is my opinion that the screen consumes most of the current, assuming you're not a "gamer" or streaming music or other content. Running with dark themes in your apps (as you can), as well as keeping the brightness reasonably low (auto-brightness should help most users here), are good steps to take.
The GP2A light sensor reports 0.75 mA current consumption in Android, so I have a hard time believing that turning on auto-brightness is any worse that running at similar manual brightness levels. If the phone were to be able to run for 18 hours with the screen on (which we know it can't), it would be averaging ~100 mA -- the GP2A would account for less than 1% of that. Of course, that 0.75 mA may not be the correct number. I'm hoping to see if I can do some measurements on the screen drain at various brightness levels, as well as confirm that the GP2A draws minimal current itself. (Unfortunately, the I2C version of the light sensor used in the SGS4G and other phones does not seem to have a publicly available datasheet.)
I think that the way someone uses the phone has a significant impact, even day-over-day. I know that Hefe Kernel v0.8.0 and v0.8.1 have no meaningful differences in how power is managed. The report that one is noticeably different than the other says to me that day-to-day differences in how a phone is used, even when the owner thinks they are using it the same way, are perhaps more than may exepct.

Werd to your grandma!
Good post Jeff!

Good post Jeff.
Sometimes something as simple as playing a game and then switching to something else without the game exiting properly can do it. Once or twice a day on my PC, I'll go to my task manager and notice that IE or Chrome is still running despite my windows being closed. It's stuck in limbo. On a PC, it may suck up a bit of RAM or CPU cycles but if you have 6cores/8gb like me, you don't notice. Something like that on a phone can suck up battery life like a hog though.
Installing 1 badly coded app from the market can do it. Viewing webpages with more of a white background can affect battery life. There is a million things. It's like laptops. They may advertise 6hours battery life. Sure on the dimmest settings with the screen turned down and very few apps running. Stream and HD movie from Netflix and watch how that 6 hours turns into 2. lol.

Thnak you very much good informantion about battery life.
I understand what you say.
About my post.(I use cMiui and Hefe kernel 0.8)
WIFI I advanced setup Keep Wi-Fi during sleep -> Only when pluggged in.
I tested both of this hefe 0.8 and 0.8.1.
0.80 is wifi off when phone lock.
but 0.8.1 is not.
kernel version : 2.6.35.7-Hefe-ics-00044-g151987a and
2.6.35.7-Hefe-ics-00046-g83ec25b
Do I something worng?
I am not complain about your KERNEL or ROM.
I'm very glad you guys about good efect,time and everything for make good ROM and KERNEL.
Thanks again.

I don't think you did anything "wrong" at all!
The control of the WiFi is mainly a ROM thing. Android says "turn off the WiFi" and the kernel does it. I'm puzzled as to why you are seeing a difference. Since v0.8.0 and v0.8.1 are the same as far a WiFi goes, I suspect something else. Perhaps settings not "sticking" between flashes? If it happens again, logcat and dmesg might provide a clue as to why. If you do would you post in either the Hefe Kernel Q&A thread or the Q&A thread for your ROM?

Hi Jeff
Thanks for the detailed posts.
Did what you asked : got 96% after 7 hours of no use, no charge. Deep sleep is 98%.
So I come to conclusion that wifi is sucking up the battery on miui. It has very good reception and always shows full bars for all spots.

I installed 'Better WiFi' (from the creators of BBS) and set it to open wifi connection only when screen is on and keep it if there is network activity.
Left it at night and dropped from 65% to 35%.
I'm now sure WiFi is over draining when opened.

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.

Battery stats is a myth: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
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

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.

The major kernels are faux franco and bricked. I am on bricked atm but all of them have apps to tweak settings as needed.
If you want battery I suggest bricked or maybe a dialed back franco

Do you have a Pebble by chance? Causes a bluesleep wakelock, other bluetooth devices don't seem to do this. Just a thought since that is the only thing destroying my battery life and I have like 100 apps.

I'm running SlimKat+Faux also and am getting really good battery life. I'm running Faux's recommended settings and as long as I don't use the tap or sweep to wake, the phone sleeps like a baby. I get pretty much crap phone signal everywhere in my area so I don't get massive 5+hour screen on time but it's quite more than enough to take off the charger at 6am and still have around 20% give or take when charging it up at 10pm. Usually getting around 2-3 hours screen on time with about 2-3 hours bluetooth music streaming a day.
