[CM9] Battery drained with no reason - HTC Sensation

Sup' XDA forum !
So, I recently installed CM9 on my HTC phone (2 weeks ago).
Since 5 days my battery life is very low.
For exemple today my screen was on around 30 minutes (without the battery loader) and the battery is already very low.
Here you have 3 screenshots of the battery utilisation :

You can see that the screen seems to be the mainly problem of battery drain, but on the second screen as I said before my screen was turn only 30 minutes a day ! It can't drain 60% of my battery only with the screen on 30 minutes !
By the way the phone is many times in activity ("awake") and I don't know why.
I turned off the Wi-Fi connexion but that does not change anything.
I don't know what "mobile standby" is corresponding to, this is totally abstract...phone idle and Google services too...
I disabled the e-mail synchronisation, but same problem.
Anybody can help me please ?
Sorry if I commited mistakes in my sentences.

Do you have "Restrict background data" enabled?
Also are you using any management applications?
Regardless CM9 with its standard kernel is known to be juice hungry. I'm currently back on CM9, now using the "Stable" release. Still testing battery life. But I can tell you I've underclocked the "off screen" processing, and also using "medium" auto-kill settings in System Tuner, and my phone did not drop a single % over 8 hours of inactivity (sleeping) but quickly dropped 5% when I used the phone in the morning.

There is a data connexion limit with my mobile phone operator (250Mo a month) and I reached the limit some days ago.
I don't know if there is a connexion between my problem and that but if I reached the limit there's no more data.
I have a task killer to check if there's something that should not run but nothing special. I had no problem before I don't know why now there is one.
Anyway I restricted the background data I'll give you a feedback at the end of the day or tomorrow.
(Again, sorry if my sentences are some times confused.)

Regardless of whether you have data with your carrier or not, having background data 'on' will use more battery, as the mobile data service on your phone stays somewhat open.
In saying this though, it doesn't explain why you are getting bad battery life all of a sudden.
Have you recently moved house? To an area of bad reception? A phone that is constantly trying to find signal will drain the battery much faster, then a phone with full signal.
Have you installed any new apps recently? Might be some juice hungry new app running in the background?
Normally if this happens all of a sudden, it's generally for a valid reason.

I disabled background data and I had no problems anymore.
I recieved my monthly 250 Mo data yesterday, re-enabled the background data and everything works fine.
Thanks!

[Q] Batt consumption after OTA update

Did anyone notice a change in battery consumption after the ota update?
Before the update I was getting to 97 percent after about 3 hours of the phone in idle - almost no use at all, no WiFi.
now It got to 94 percent with the same usage apart from 3 photos taken, could be that i'm just too harsh about it.. but still - wanted to check if anyone noticed anything.
edit: also I forgot to mention that I added the "mail" widget to one of the home screens, could be the power taker?
Probably the mail widget and the picture shooting (takes much ressources).
I haven't noticed any increased battery consumption, but it is probably to soon to tell.
Also forgot to mention I added two 'folder organizer' widgets , two folders which contain apps and games.
tomorrow I'll start off by removing them + the email widget and see if there is a difference.

are u really lookin' after for a 3% change in a 3h time ? maaan ... this could be a simple measure problem ... dont it take it too serious. if ya want to test it, maki it at least 10-20h run in standby (airplane mode on) ... it doesn't that accurate.
Yeh yeh I know I know I'm exaggerating.. I'm just becoming insane when it comes to battery life for some reason.. guess it's still the HD2's influence
It shouldn't bother me that much as it is.. I have a charger in my car plus I'm almost never gone more than 9 hours from home, which should be more than enough for the batt to last.. call me crazy it just occupies my mind
Update: strangest thing.... I just checked the phone, didnt turn the screen on since exactly one hour ago, batt was at 83 percent... that's about 9 percent in one hour!!!
removed the folder organizer folders, rebooted the phone, and suddenly received sms messages I should have received last night
now that's becoming something I should put my eye on.......
Update -
Well after another hour, phone only dropped 1 percent, i'll try to isolate the problem by adding the folder organizer widgets back and check in in one hour to see what the batt has to say..
If it'll drop 1-2 percent I guess there was some glitch causing the phone to not get calls\sms's and drop the batt usage about 10% in one hour..
Another thing I'm going to do is let it drain until it turns itself off and then fully charge it, I'v heard you should do that like 5 times when getting a new phone.
Update - 1 percent after another hour + folder organizer folders.. so, guess it was some major batt\radio glitch since last night until i rebooted today (phone was on charge all night)
I noticed that the setting 'Best WiFi performance' adds a serious battery drain when enabled after installing the FOTA, I was loosing 8-9% an hour compared to 3-4% before the update. Disabling this brought me back to 2-3% an hour. I still have a way better WiFi-connectivity compared to before the FOTA with this setting disabled.
I actually never checked that option but yeh I get your point, all is ok now I'll update if anything weird will happen, i'm getting 1-2% an hour

I charged mine up the night before last and have used it for internet, Angry Birds, whilst waiting for my clients and a lot of texting and about 10 mins of calls. This morning It's at 60% as I post this. I've noticed a huge difference since the upgrade and the phone is nowhere near as hot since the upgrade either.

It was a glitch 100%..
yesterday I let the phone drain itself (1day 7 hours - after the incident with the battery gone down 20 percent in 2 hours) then I fully charged it, turned it on last night before went to sleep, phone has been on since last night approx' 12 hours now - gone to 97 percent!! this is awesome!! I'm gonna' let it drain again a couple more times and this all over again
Battery lasts for approx 11-13 hours. Loosing 8-10% each hour with no usage at all.
It is updated. Reset to factory defaults. No extra apps installed. Just gmail, htc hub sync, wifi and that kind of stuff. No friends stream or Facebook or twitter.
What should I do? This is totally unacceptable.
Anyone tried to send it to service for fix?
first of all let the battery drain itself and let the phone shut down on its own, then fully charge the battery while the phone is off, do this for 3-4 times it will increase the battery's life span and charge time.
also check for the "best WIFI performance" as described in my post above, if it's checked uncheck it.
use auto screen brightness.
most important of all and may be causing your issue - check the stats of your charger, the charger I got with my sensation is imho faulty, it makes electricity noises, so I went back to my old HD2 one - perfect - the most important thing to check in your charger is the output voltages - it has to read 5v---1a - nothing different.

I think its better not to use auto screen brightness but use a fixed setting (maybe at around 25-30% brightness level). The reason being, the processor will have to be worked upon constantly to find the optimum brightness level and that would consume power!

Personally I believe the process of identifying the lighting and adapting to it doesn't take much effort from the processor, and based on my phone - the screen does consume energy but it will last 48 hours with the auto brightness setting on so why not use it? it's one of the good options we have in our phones and i really like it that when i go outside to the sun it'll increase the brightness in a millisecond.
the guy from the post above that's getting 10 hours of usage has a problem that I don't believe has something to do with his screen brightness unless he keeps the screen turned on all the time....
I updated to 1.35.xxx.x in the morning and after that the battery meter has only gone down by about 20% in the last 7 hours or so! The phone was off charge in the morning and I downloaded the update over my 2G connection. I also put on a live wallpaper just for fun! No calls made/received but few texts only. No games played. Surfed a little bit on internet (maybe 10 mins).
I'm liking it

[Q] Ridiculous battery life without internet

Hi,
I have got the HTC Chacha for 2 months and so far, I have not been disappointed about the battery life. However, once my internet expired, my battery life decreased a lot. When not using the phone, with as least as possible apps running in the background, it does not even last a single day. When I go into the battery menu, it says that standby drains my battery, but with internet I never had this issue. Does anyone know how to solve this, cause I am not satisfied with this...
+1, same issue.
Quite weird... I'm getting 10 hours with no battery drain if I don't use the phone.. With little to moderate usage I get 2-3 days.
I've never tried more than a waking day but doubt it would go further.
One day I'll try 2g only, no WiFi mobile data and Bluetooth to see how that goes.
Sent from my HTC ChaCha A810e using Tapatalk
I had a little think, and perhaps it is Whatsapp, Facebook chat or facebook. However, where applicable I turned off auto-update, yet my battery life is still quite disappointing... So could it be Whatsapp?
You should (as a test) reset your phone to factory data, set it to 2G only and leave it there; auto-sync disabled ofc. Just check how long will it last 'till it's off. Mine lasts about 3-4 days.
in a fully charge around 3am this morning(now 3pm noon) with some SMS & few tries to call my mum(but her phone is off -_-") till now my battery still shown full bar. i'm in 2G/3G mode but off all background data & wifi. Things that really eat battery is those background sync with data usage. normally is with emails, facebook etc...

I had internet, but I don't have it anymore, so settting it to 2g won't work...
just do a factory reset & set it up normally for daily usage & try does it still drains much battery. set it to 2G only(GSM only if u'r using it) mode. as i know if u enable 3G & Wifi it will keep searching for network every don't know how many mins/secs even u don't have it. that will drain ur battery.

Quick battery drain & constant data being sent since 1.78 OTA

Hi,
I've got an HTC One S since a few weeks (got it with the 1.57 FW I think). It's a stock one, not from a carrier. No branding.
The battery life was great, 2 to 3 days with normal use.
But yesterday evening I proceeded to the OTA update and since then, trouble began
Battery life is much, much lower. After 12 hours standing on my desk in the office, I got 10% remaining!
Anytime I switch the screen ON, I see there is some data being sent (or received) because the "arrows" are full. If I check in system panel lite, there's always 1 or 2 kb/s of traffic.
Also, the phone is a bit warm, quite often.
Has anyone else noticed this? That's rather annoying :/
Could be faulty? I have the same phone with no carrier or branding and not had any problems at all.
Like faulty hardware? Seems unlikely to me since it worked well with 1.57. Also, sending data isn't hardware related
Here are some details.
In Mobile usage, just for today (less than 24h)
"Media" has used 13MB of background data
"Android OS" has used 5MB, also background
Android OS gives no more details. Media is told to include "Download manager" "DRM protected content storage" "Media storage" and "Downloads"
This sounds like a lot of background data :/
Try an app called Badass Battery monitor. It should tell you what's eating your battery.

I have to say, this phone, at least mines, seems to have a pretty bi polar battery. It's got a case of ADHD.
For example, just the other day, I had the phone fully charged when I awoke at 9am, after playing Temple Run, surfing the web, using GPS, streaming and listening to music, playing more Temple Run, fiddling around with the OS, checking emails, sending texts, talking on the phone a bit, downloading apps, with about 25-30% brightness, I ended up with 18% battery remaining after a good 11 hours of very heavy use. I was quite pleased, considering the inordinate amount of usage I had with the phone all day.
(BTW, I use Juice Defender, which has helped tons in reducing battery drainage for almost every phone I've owned in the past 3 months, including the One S)
Yesterday, I had the phone charged at 100% when I awoke at 9am, with a little bit of use, by 12am, I had 63% remaining, same brightness, but with much much less use then the day prior. By the time 3pm hit, I was at about 30%, and by 5pm, it was drained to 18%, mostly on standby. By my estimation, that's 8 hours of usage, same brightness levels as the day before, using Juice Defender, but with much much less fiddling around with pretty much everything on the device.
I went ahead and disabled Juice Defender today to see if it would make a difference, and the battery actually got a bit worse, so I went ahead and re-enabled it and it immediately improved.
So I'm a bit perplexed, I haven't gotten any official updates, still running on the original stock build, but ultimately, I guess this is what is too be expected with an early build. Hopefully future updates WILL fix these issues and not hinder them more. Granted it's still much better then my HTC Amaze and Galaxy Nexus, which drained 4% the moment I took them off charger.
Thanks for your input, I'll check again today how the phone goes.
I played with all the settings and menus yesterday, and found something strange. In the "downloads" app, there was a "system update" download. That's quite normal since I downloaded and applied the OTA the day before. But it was referred as "ongoing", like it was still downloading a part of the OTA zip file AFTER I applied it (and rebooted a couple of times)
In phone settings, about, updates, it was also written "ongoing"
Now this is over (I don't know why and how) and the network usage seems back to normal. I'll try today to see how the battery drain is
Anyway, it's s strange the phone was still downloading the update zip file after having applied it. AND that it was downloading it on the 3G at a very lowered bitrate (like background) while I downloaded it on the wifi the day before
Anyway...
The battery life of my One S seems to have declined as well since the update. Before the update my battery lasted 2 days easily with moderate usage. Now I have 20-30% left at the end of the day from a full charge since 9am. This is with very light usage (mostly on standby from 9 to 5).
I did turn on best wifi performance recently so I just to turned that off to see if it helps but I really doubt that.
Hello guys, I have same problem, but my phone wasting energy on "phone radio" process, just look at screens below. I tried using stock Rom with last update, trickdroid, and now it happend on leedroid v.2 . Btw I changed 4 micro sim cards with several providers, but no result. I really need help with this issue, because my battery draining very very
fast...
Thank you

I had a similar problem a few days ago, using Lee´s ROM.
I noticed that the drain had something to do with autosync. As soon as I turned off autosync (leaving mobile internet on) drainage went back to normal.
I still don´t know what caused this since I only had the google account, weather and dropbox installed.
Anyway, after doing a fresh install, the problems seem to have gone.
Of course I can´t be completely certain of it until some more days of testing/usage.
I also noticed quite a few problems since the latest OTA update.
Not only does the battery drain fast, the phone also feels extremely hot when browsing on 3G.
The phone does cool down pretty quickly when turning off 3G but it feels like I burned my hands
Here are a few screenshots.

I also experienced weird things when connected to EDGE (2.75G).
3G (HSPA) coverage on BASE (KPN) sucks in Belgium
Look at the video below for more details.
Has anyone else experienced this yet?

I also contacted HTC about this issue and they recommended a hard reset.
Unfortunately this doesn't help at all, I still get these weird glitches
mattionline, can you get a logcat when the phone's doing this weird stuff? It looks like the Home button is being pressed repeatedly and if logcat confirms it then it's probably a hardware problem.

Do you need root to make a logcat ? My phone is not rooted and I'm not planning to do it. How can this be a hardware problem ? I never had this problem before. I'm sure that it's a software bug.

I just fixed someone else phone that had the exact same symptoms. In the end I narrowed down the problem to one of his weather apps.
He had a live wallpaper that reflected the current weather, weather on his lock screen and a beautiful widgets weather thing. I never did figure out exactly which one it was I just turned off all there and told him he was crazy.
I don't know if it's something "weather" related for you but it maybe it will help.

you don't need root, just enable usb debugging in development options and connect the phone to your pc. You need to have the android sdk installed.
Sup guys , some of you don't seem to realize that there are many reasons why your battery drains, what you might think is, "quickly". A few tips to keep minimal battery out put...1 keep brightness down, the screen itself sucks juice probably the most. 2 check your apps, some apps send and receive data and/or are kept running in the background. You might have to enable/disable setting on shove apps. 3 widgets, widgets like battery meters, CPU meters, things like this constantly refresh to keep real time info. That also eats up alot of juice . 4 Turn off WiFi or any other thing like that when your not using it. WiFi continually sucks nice. Lastly, invest in some app that will help you close apps. Basically, tweek everything you might think that the os can run without. The less your CPU has to do, the more juce you save.

This made me lol hard.
Best advice ever.
But yeah, on the 1.0 version of Leedroid I had quite some drain, too.
When I turned off autosync it went back to normale. I only had my google account, dropbox (with syncing off) and the weather thingy set up and never figured out which one was resposible.
After installing Lee´s 2.0 ROM everything is fine.
I suppose there really is something wrong with the autosync and maybe with the weather stuff in particular.
My problem didn't go away with stopping auto sync, even without it, I had a constant data flow
Anyway, I rebooted the phone twice and the issue was gone.
It happened again a few days later, after the phone did shut down because of low battery. I put it on charger and turned it on, then, I noticed the 3G arrows were always on. After I unplugged it from the charger the battery went down in 10 hours. After a reboot, problem gone...
Since then, nothing...
And please note than when the problem is here, it's media and android os using a lot of data
I have been having one S problems too - I am on my second phone after the first one became reliably unresponsive every time I turned on mobile data. More relevant to this discussion, my battery died shockingly last night. Normally it drains at a few percent an hour when I am not using it (i.e. when asleep!) but I woke this morning to find it totally dead - that is 30% plus gone in 5 hours without it being in use.

Extremely bad battery Life for 3 Days.

Hey,
3 days ago my mobile Internet flatrate ran out, I don't really think that this has anything to do with this but I try to provide as much information as I can.
My Nexus S was bought December last year and never really had any problems.
But now for 3 Days I have to charge that thing every damn day and the battery only lasts 18-19 hours instead of 2+ days. I haven't really used the phone in the last 3 days except from recieving calls and using whatsapp.
I have also not installed any apps in this time.
Here a screenshot from my current battery live. (Seems to be always awake)
(ICS 4.0.4 Rooted, Stock Kernel, Stock Launcher.)
Thank you guys in advance!
What does it say is the top consumer of power on the battery usage percent chart. We can't help you very much without that. Also, grab BetterBatteryStats. That will help tremendously as it can damn near narrow it down to a single culprit.

EDIT: I just reinstalled Whatsapp and will now wait what the battery says in a few hours before I buy betterbatterystats.
Thank you so far, will report back.
Yeah. Those two are probably trying to "phone home" constantly, thus causing a drain. That may be what the issue is. From the looks of it, it looks like your signal isn't stellar either. How good is Whatsapp over EDGE speeds? The 3g connection just might not be strong enough, trying to search for a signal and also draining the battery.

Your guess is quite good, because in my room and ONLY in my room there are some severe problems with network connectivity for almost everyone.
(But battery life was good just a few days ago?)
I currently have no mobile Internet and only use WLAN. Just disconnected phone from charger and will now see how it runs.

If you have "no mobile Internet" and WiFi is off (as in screenshot), this is your issue. The android processes are trying to re-connect keeping your phone from deep sleep. In Mobile Network Settings, disable Data. Turn on WiFi, and set Keep WiFi on during sleep to Always. When you are out of WiFi range, disable background sync.
I've noticed something on 4.0, at least in my case. Huge wake locks for no reason in airplane mode. The phone home thing is most likely the cause. Google must have changed something in the way their apps operate because this never happened in gingerbread for me.
Well, so I have observed it a little more and battery usage by google services is now up to 70%.
Thank you for the suggestions I'll try now.
But why the hell does this issue come just now? I have 4.0.4 since it came out and the issue just appeared about 5 days ago.
I wish I knew. I've got mine in airplane mode now, but no SIM in it. I've got a G2 as my daily driver now. The Nexus hasn't had any more of the airplane mode wakeups strangely enough though. Wish I knew what was actually causing mine.

So to report back again, I tried SpookyTunes suggestion for one cycle of battery life.
Then after recharging I went into the app management and force-stopped the google services framework and deleted the cached files afterwards.
So now I'm back to 3% battery usage (from Google Services Framework) for the last hour.
I would give it more time to see what it uses over the course of the day.

Unsolve battery drain

Hi everyone,
I need some advice from the community. I've had my XT925 for almost 2 years now, and in the last 6-8 moths I've been having weird battery drain that I couldn't solve. It started back on JB a while ago, and I thought "oh hell, KK is around the corner, it'll go away when I wipe everything". I was mistaken: I first tried the soak test leaked KK, and had the same erratic behaviour. And when the final release became available, I reflashed a full stock JB then flashed the zip OTA posted in general. I'm now on 4.4.2 stock moto kitkat.
I hardly last a full day, without a heavy usage. Many SMS (10-50), maybe 1-2 MMS, wifi ON most of the time at work, phone forced to 3G (4G cover is sporadic and when I turn it on I have a lot of 3g/4g switches). In the last week, I've frozen nearly every app I had with TB, to (hopefully) isolate the ones that drain too much battery. No luck so far.
Today I've decided to take a series of screenshot so maybe someone can help me troubleshoot what's wrong. They are attached to this post. I don't see anything out of the ordinary, but I'm no expert, so maybe someone can elighten me on any abnormality. I had roughly 40 min of vocal call today, which is a lot compared to my usual usage (average, maybe 3-5 min a day of voice call). This may have contributed to drain slightly more today, but there is not so much difference at the end of the day.
Basically, I recall lasting easily 1..5 days with the phone stock out of the box. Now, it's hard to reach >12h. I thought maybe the battery was dying (although *#*#4636#*#* said it was in good shape) so i replaced the battery by a brand new Moto one last week. There was absolutely no change at all.
So... here you go: any idea on what could be causing the drain ? Obviously I've cleared cache and wiped data many times already, and I'd like to avoid doing it again and again and again. Note that on the screenshot, there is many apparent time with bad signal. I have no idea why it shows like this since I'm always 3-4 bars at work. This is weird, and came with KK (JB sowed green signal at the same place).
Thanks for your help!

Hi everyone,
I need some advice from the community. I've had my XT925 for almost 2 years now, and in the last 6-8 moths I've been having weird battery drain that I couldn't solve. It started back on JB a while ago, and I thought "oh hell, KK is around the corner, it'll go away when I wipe everything". I was mistaken: I first tried the soak test leaked KK, and had the same erratic behaviour. And when the final release became available, I reflashed a full stock JB then flashed the zip OTA posted in general. I'm now on 4.4.2 stock moto kitkat.
I hardly last a full day, without a heavy usage. Many SMS (10-50), maybe 1-2 MMS, wifi ON most of the time at work, phone forced to 3G (4G cover is sporadic and when I turn it on I have a lot of 3g/4g switches). In the last week, I've frozen nearly every app I had with TB, to (hopefully) isolate the ones that drain too much battery. No luck so far.
Today I've decided to take a series of screenshot so maybe someone can help me troubleshoot what's wrong. They are attached to this post. I don't see anything out of the ordinary, but I'm no expert, so maybe someone can elighten me on any abnormality. I had roughly 40 min of vocal call today, which is a lot compared to my usual usage (average, maybe 3-5 min a day of voice call). This may have contributed to drain slightly more today, but there is not so much difference at the end of the day.

i would get gsam battery monitor with the root companion (second app) so you can get a better idea of whats going on. some shots of the app view screen, then change the view to view time held awake, then a couple shots of the details on the highest ones.
you can then get an app called unbounce that can limit the wakelocks, but it requires some reading so you dont break anything.
if you could take shots in English that would be great, otherwise i wont be able to help much with the diagnosis.
I was trying not to rely on wakelock limiting apps, as there's no reason for the drop from 1.5 (2) days to 12 h, with all custom apps frozen. I didn't know unbounce but the same goes for Greenify. I'll try the widget you mentioned and report back.
edit: yup i'll switch to english for the shots next time.
Oh and I forgot to mention this: from time to time, the drain won't be so apparent (e.g. 40% remaining after 12-15 h) and in a matter of minutes, the phone will drop to 10-12%. However it hasn't happened sicne I last turned off 4G, so maybe it was due to constant 3g/4g switches.

no doubt, in weak and especially no signal areas, it will burn through battery like crazy.
Here it as, after a nearly complete discharge. Phone unplugged around 10am, 12h15 later I'm at 10% remaining, with not so much usage. Screenshots are attached. What's weird is that in the last 1h30 the phone has been off wifi (slider "Wi-Fi" is off in settings) but battery status still shows a connected wifi. However you can clearly see a huge drain due to wifi being off and 3g being on (it's the only part of the day it's been using cellular data: I was at the restaurant therefore no wifi). Possibly locatin services using the wifi even though it was disabled ? Anyway I'm not sure this could cause such a quick drain...
edit: as far as the signal bar color in battery status, I've found that grey-yellow stands for "signal 3/4", so it's rather good (solid green is signal 4/4). So it's probbaly not that either...
Ooops forgot the "time held awake" shots. It's definitely Google services messing around, but what... (details of Google services in previous post)

some of those push the limits of what i would like to see personally, but none appear out of control to me.
im really not sure how you would go about taming some of that down though, without using a couple apps you dont want to use.
imo, you would need to control some of the wakelocks, and/or disable some of the receivers you done use.
the couple "nlp" wakelocks from google are going to account for a good bit of its waking. nlp is nothing more than google using your location information to build a database from it.
here is whats known about some of the more common offenders, and the testing results from limiting them.
That's what I feared... I'm usually not that bad with messing with the phone, and couldn't see anything obvious either. I've disabled "using wifi to locate" in wifi settings, I'll see how this drops the nlp wakelocks, for starters.
If anyone has a better idea, please don't hesitate

i have use quite a few of the more popular battery saving apps over the years. i just came across this one yesterday. its shaping up to be the best i have used to date. i wasnt using my phone except for a few minutes this morning, and it went 5 1/2 hours and was still @ 100%.
i also use greenify with root + exposed.
did you disable FAST DORMANCY? I have done it while on JB ? IT did not cause any prob.
Haven't disabled it, mostly because I've never been able to determine if it was being used by carriers in France or not. I've read somewhere that it wasn't, but the source was hardly documented. I've tried to disable it in JB however, and did not see any improvement.
Right now I've disabled Google Now and location history things. I'm trying to reduce the wakelocks as much as I can using settings available from stock rom (and understand at the same time what was causing them). Battery drain is still high, but I'm testing things every 10 min or so, so it's not really representative. I'll update here when I have a better idea of what's going on.
Another thing of interest is xposed with new module called Unbounce. There is a thread for it. All about minimizing wake locks
A few thoughts so far. I haven't tried Greenify or Unbounce yet, this will be the "final stage". For now I'm trying to minimize wakelocks as much as possible without installing third-party apps.
Here are a quick review of what I've found (NB: in the following I translated the menu names myself from french to english and didn't check their actual name... but it shouldn't be too hard to figure out which ones I'm referring to if the name is not exactly right):
1) Disabled Google Now and all "Google Location settings" (i.e. "Update location" and "Location history", found within "Google settings" in the drawer).
2) Set location settings to "minimize battery", that is with network and wi-fi.
3) In wi-fi advanced settings, disabled "search always available"
4) Locked the phone to 2G/3G only, because 4G coverage from my carrier (Free Mobile for the frenchies here ) is erratic at best, and caused many 3G/4G switches
5) Some "light" de-bloat (froze all Google apps I'm not using). At first I froze all my apps to mimick a fresh stock system, but there were really not that much difference.
Note that all the tests were ran (mostly) in the same location, on different days, so signal quality should be rather constant (and good) and therefore is not acting as a confounding factor in my tests.
Whats happening when 3G and Wi-Fi are both off ?
Obviously, disabling 3G and wifi gives a very good battery life. I'm talking about something like 2h screen-on and probably 30-40% after a full day (9am to midnight, roughly). I'll double check the exact values for this and update this post with a screenshot asap (= in the upcoming days). With this setting, wakelocks actually correspond to screen-on time. So it's probably the best one can achieve.
edit: 1h of voice communication, 1h15 of screen-on time, 10-15 sms, 1 received MMS (had to enable 3G a few seconds for that of course) => see Screenshot_2014-10-27-23-22-14.png
The decrease at the end corresponds to wifi+3G when I got back home and started using the phone "heavily". Roughly, 40% decrease in 12h. That is what I call a good battery life. Notice how the wakelocks closely match the screen on periods.
Whats happening when 3G is ON and Wi-Fi is OFF
We've discussed a bit the "fastdormancy" thing earlier here. Spending a whole day on 3G made the "modem fastdormancy" process drain a high share of battery (10-20% ? Can't remember exactly, but it was in the top-5 list of draining apps, and had a big wakelock time). Further proof that my carrier doesn't support it. I've therefore edited my build.prop to set
ro.mot.ds.fastdormancy.disable=true

After that, the process was not found anymore in high-draining apps, and battery life was a little better (again, no values here, I'll update in a few days after I run the tests again and double-check everything).
Can't say much about Google location, but I'd say most requests were not executed.
Whats happening when 3G is OFF and Wi-Fi is ON
Wi-Fi at work did not cause any interesting drain. The phone sat there and was connected all day-long. There were probably a few Google requests to determine its location, with some nlpwakelock, but not really interesting.
What was really interesting was the behaviour outside my workplce (e.g. on the street). I have in my "known networks" some wi-fi hotspots (FreeWifi) that are enabled with my DSL provider: they provide me with codes from my contract that I can use in the street if any other of their customer has a wi-fi enabled on their modem (their is a dedicated SSID broadcasted from their modem). The phone connected automatically whenever it detected this SSID (which was... really often), but the captive portal (to enter credentials) was not filled, because the phone was in my pocket. This caused HUGE wakelocks and drained the battery incredibly fast. I'm talking about draining 50% in an hour or so. I could even feel the phone warming up in my pocket.
So, conclusion here: I think Wi-Fi could be a major cause of battery drain if you have some fav SSID that require credentials through a captive portal.
I'll update in a few days if I find anything else, and to add values to what i've stated here.
Hope that helps!
