Hello, let me cut to the point. Testing a few nights while sleeping from around midnight to 7:30am on different firmware versions, i can confirm.
- Stock, unrooted, firmware verison Taiwan, 253: BetterBatteryStats drain overnight : 0.7% per hour
- Stock, unrooted, firmware version Hong Kong, 253: BetterBatteryStats drain overnight 0.3% per hour (Update, last night was 0.1% per hour, woke up in the morning with 100%)
In conclusion, not all firmwares are created equal. If you have the dreaded battery drain problem - try another regions firmware. The HK version definitly does not has the drain problem, and its quite a generic firmware, so you can customize it to your region no problem.
In Both firmwars I had WhatsNew, and all smallapps hidden/disabled via the adb "debloater" app.
PS: Taiwan is original firmware of my phone, I am expat living in Taiwan.
Why HK firmware has more battery? lol

I also noticed this on my old M2 when I ran customised tw firmware for a while the battery life was way better than the customised UK I was originally running never could work it out.

Nice.I try it.
At now i have this Bat.: -5%(98% to 93%) [0,5%/h] at night in airplane mode.
I try last night HK firmware. And now -10 % in airplane with turned off some apps like google backup,most of xperia apps and etc. Usually i use firm for Russia region also Xpower 3 or 4.In both have a same result 5-7 % per night in airplane.
how do you disable whatsnew without root?
I think the firmware 253 is the same for battery management for all versions.
I think a good thing to do sometimes is clearing cache in recovery. For me it help when performance become slower.
But few parameters can really change your battery drain like the Temperature in your house, usage during the day, network level, running process, humidity....
Maybe that's because some differences of LTE bands support?

LTE is disable on my phone on all tests. All my testing with done with 3.5G and wifi off.
VoLTE is something i noticed taiwan firmware had, but HK didnt. however I had it turned off in both cases.

I know most people most people would like buttery is the same for all version. That why I am posting. Caches etc all cleared, phone got full wipe when switching firmware.
This test is verifiable and repeatable. I tested both firmware at east 2 times each before posting, and the results were the same every time. Same phone, exact same apps installed, same firmware version - different region = different battery drain.
Can someone upload .253 stock kernel with SU and DRM fix for me? I want to do some further testing but I'm not able to extract it myself for the next week.
the Wifi-allways on bug
did somebody changed already the default:
Settings->Wi-Fi->Settings->Keep Wi-Fi on during sleep
(the good old bug - if you look at the other threads)
one solution I had for battery drain even in marshmallow is to remove the sd card. Yes, I do know it defeats the purpose but I'd prefer not having to worry that my battery will drain by 30% overnight.
SDcard?... did you try another one...
How can I know which firmware do I have? The number is 32.0.A.4.11
32.2.A.0.253 here and I'm seeing Android System keep awake for over 11 hours.
Google Services mobile radio active for 27mins.
No other mentionable apps.
Any luck with the battery drain?
Some good news for me and maybe for others may be helpful.
I flash clean new 305 FW and modified stock kernel from here
http://forum.xda-developers.com/z5-compact/general/customized-stock-kernel-32-2-0-305-6-0-1-t3477464
With root i delete some system apps (mail,gmail,gdrive,maps,whats new, all about small apps and etc.)
Now 3% at first night(9h) after flashing FW in standby mode and all data off without stamina.Its first good result for me.On all others 253 custom kernels was ~7-10% at night sometimes more...
I stay on this FW and kernel.

8 hours gone and I'm left with 49%. With the standby estimation, I should be good to go through out the night. So I hope it should be the same as previous. Just note that I'm a moderate user .

Draining like hell. Can't even last for a day due to radio issue . The issue is there in .283 & .42.
i've not seen a fw that had great battery life...
on cm041, miui the drain was there as well....
what is wrong here....
Slightly off topic: I'm getting about 8-10 hours with pretty heavy usage on CM7.1.0.1. When I leave it on standby, I have about 10% drain after about 8-9 hours of standby, with the occasional time check.
And back to topic, thanks for having the generic SG ROM here, I might go back to this as I have some issues with Wi-Fi tethering on CM7.
Just to add on, i had previously used the .283 version, battery was good. Then i started to root and unlock bootloader, and installed the doomlord v12 for .283, battery drain about 10-15% overnight in 6hrs. Days back, I had flashed the SG ROM .042, the battery was good again, averaging 3% overnight. Its proven to be good.
3% drain overnight is impressive. Which kernel are you using? Stock .0.42?

Same experience as me. But I turn off the data connectivity at night.
As far I used (I used almost all the versions, I guess) the .368 firmware is the best of battery usage. I usually get 24-26 hrs of usage (I would say pretty heavy, with all guns up... [BT, WiFi, GPS]) out of it, compared to this .42 firmware, I can't cross 15 hrs mark!!!
But from what I experimented, I understand that it's the baseband that is giving problem. I notice that there are many users from SG here and specially from SingTel, if you guys observe closely, the network coverage is poor with this firmware compared to the previous .145 firmware. So I'm planning to flash back the old baseband on to the new firmware and give a try whether the battery life improves together with the network coverage.
How do I know which firmware I am using?
Ok, I am on .0.42 world generic now. Let me monitor and revert.

I'm on stock kernel, and i'm using Juice defender Ultimate, let it auto manage my battery-drain stuffs, so i need no worry on forgetting to switch off any batt drain functions. I"m not sure if the SETCPU profiles works, I just enable the profile when screen off I set to 245MHz max 122MHz min. Mine is M1 set.
Kinda tired of flashing custom rom/kernel.. there's always some problem with the features, i.e. 0 batt, wifi cannot connect, batt drain etc etc.. stick to stock for the moment.. Root hp is good enough to play with some stuffs for the moment. Especially ad free.
Personally I don't like any programs that turns off my data to save the battery. It defects the purpose of having data plan moreover, you miss the updates (I've tried lot of applications like Juice defender and I experience the same issue...missing the updates, even the Whatsapp messages are not delivered to you on time).
Now I've flashed the old baseband (from UK .368 firmware) on to the latest firmware (.42 SG) for testing to see how is the battery drainage
hi all，have downloaded and flashed the LA2 multi-csc firmware and completed a few battery cycles. I can report slightly increased performance from the previous versions, but signal strength is not great. Battery is way worse, I literally have to charge twice a day. Once in the morning and once in the afternoon. for some reason, battery is always drained after a nights sleep, consumed mostly (>90%) by Androis OS. Swipe doesn't work as well either.
What's your experience with LA2 so far?
This rom has the best battery life of any I've used. Its the smoothest I've used, and the best that I've used.
If you are having battery issues may I suggest a full wipe is in order, there's a lot of changes in this rom and some setting from your old firmware may be causing the high OS drain issue as my Android OS usage is around 15-25% most days.
As its a beta test rom not the finished product its not a firmware i would ever use .
For the simple fact test and beta both mean what they say .

It's official if he means XILA2.
@op: either something is wrong with your configuration or you've got some dodgy application eating your megahertz.
@kitch9: my Android OS usage is always at least 60%+ with previous firmware, 25% would be amazing!!!
@JJEgan: It's XILA2 and official.
@Intratech: is there a way to find out what app may be causing this? My phone also gets warm overnight too.

I have noticed accidentally yesterday that after I had my stock headphones pluggeed in the Note, the typical curve of the battery drain became much flatter and the different wakes during screen off have almost disappeared. The moment I unplugged the headphones, the battery drain went back to the usual 2-3% per hour on standby.
I am running stock LQ3 and stock kernel. I am rooted, as I have flashed it through Mobile ODIN, over stock, rooted LPY.
I have quite a lot sync-accounts - twitter, facebook, gmail, email, weather widget etc. so I am quite used to relatively short battery life but the trick with the headphones came as quite a surprise.
Before writing this post I decided to test it today as well and it is the same.
So, could someone test this and report? I think that if this proves to be true and common, the devs could easily track what's happening exactly and sort things out, so that battery can live longer without the headphones plugged in.

Ugh...I am terribly sorry, this was meant for the General Discussion. Please, admin, move it there.
I've noticed that same if the SAR of the last samsung mobile is very low, the reception is quite good compared to other phones.
Do you notice also an improvement of the signal reception? Because if it is the case, it is that your headphones are used as a secondary antenna, giving the phone a stronger reception and less power consumption (better signal = less need of power usage for processing the signal)
This is just a theory...
After some ICS ROMs I went back to Gingerbread, mainly due to poor battery life.
When Litening ROM 2.0 was published I flashed that one. I liked the GB version a lot. The battery life was remarkable, a lot better than previous ICS ROMs. Because Litening is not much supported I tried Alba, also LQ3. A surprise because battery life was the same. I think I'll stick to ICS this time.

Alba often uses LB2 modem (from GB) in his ROMs - maybe it is the reason. I myself observed huge batterey drain on latest ICS ROMs while connected to Wi-Fi at my workplace. Fixed it by flashing ZCLP5 modem (from early "LP5 leak" ROM).

Hm, that is an interesting theory. I am not sure, however, that the headphones' cable really improves GSM radio reception. I think it is only for FM reception. Of course I have no knowledge behind that, just thinking.
I have frozen lots or apps in Titanuim Backup like:
- the whole range of SNS's
- Social Hub
- Wi-fi sharing manager
- the infamous wssyncmlnps
- software update service, etc
Also I have stopped a bunch of receivers, using Autorun Manager Pro, and disabled a lot of processes from Autostarts.
This should mean that I have opted out the most common battery drainers. I have tried to disable auto-sync for the time being, but that does not seem to be much of a drainer, so maybe the real problem comes somewhere from the modem.

Hey dimcus, i've been having this WiFi vs battery issues with some routers(including the one at home), weird enough it doesn't happen on some of them. I did read somewhere about flashing te Modem file, what leads me to a couple of questions ir you don't mind. Are you on ICS? Do i need to be root to flash the Modem file? If not, any risks involved? I'm on stock ICS LPY DBT.
Thanks in advance,

I flashed the ZCLP6 modem earlier today, guessing that it would be better than ZCLP5.
It is too early to judge but first impressions are that maybe there is a slight improvement in battery on 3G but not something worth it over the stock XXLPT that I used to have and generally battery drain on wifi seems as bad as it has been ever since I flashed ICS.
I have read that some people dared to wipe their Notes and after that most of the problems had disappeared but I don't want to risk getting some brick.
I will try several other popular modems and will report back.

Please let us know how you get on with them. Currently on LR1 modem and noticing a few strange wakelocks.
I have been with LR1 modem for about 40 hours now. What is better than the ones before is the much better behaviour on wi-fi. Other than that it is hard to tell any differences. So far 7 hours since unplugged, 1 h screen-on, half time wifi, half time 3g - battery is at 75%

Unfortunately after several different ICS Roms (From Stock LPY to Cleanote 2.20) with several different Kernels (Stock, SpeedMod, Goku and more) and few modems (XXLPT, ZCLP5) I had to go back to Ginger due to extremely poor battery life. With all roms /kernels/modems combination the behavior was very similar. The phone was going into deep sleep pretty easily when idle with very low battery drain. On the other hand when using the phone I was getting about 10% drain each 20 minutes (A little less with data wifi and all sync off). I was also getting overheating with temp most of the times over 40 deg C. This drain was almost the same even with system energy savings on. I could not understand the reason for this strange behavior considering that many other users are having great battery life on ICS with their devices. Anyone is experiencing this situation ? NB now with Ginger the battery life is ok.

Battery drain with cm10 paranoid android
I am facing a huge battery drain issue. Used the phone for downloading and playing games and general usage yesterday and battery only lasted 3.5 Hours. Need to continuously watch the battery as it drops about 10-20% on idle. Checked the wakelocks and mainly wifi related, the phone is going into deep sleep just fine. HELP PLEASE!!!

* Just listening to TuneIn radio during the night as I fall asleep (a tiny 32kbit stream) = 6 hours batterylife on fresh charge. My old SGS2 was still playing radio when I woke up. The SGS4 dies during the night. (even though SGS2 had 1650mAh, and SGS4 has 2600mAh. WTF.)
* Browsing internet using Dolphin and max brightness = roughly 10 hours total, with roughly 3h30m screen time
* some browsing, some poweramp, mostly deep sleep = roughly 20 hours total
* mobile data OFF = 6 hours screen time (which is why mobile data is probably the culprit in my specific case)
I recently installed BBB, and this is what I found on a fresh charge cycle, after about 2,5 hours of using mobile data (screen OFF) and from 100% is now just 85%. again, SCREEN OFF and mobile data has eaten up 15% in 2.5 hours. Ive been downloading stuff, screen on total 5m)
msm_hsic_host (29%)
fast_dormancy (21%)
powermanagementservice (11%)
Ive noticed these three are mostly in the top when using my phone normally during a day.
My phone is 6 days old. Its on the 9th cycle or something like this.
I tried Stock MF8 rom + MF8 kernel (Battery King and Omega)
I also tried GE kernel ausdim, aswell as stock.
I recently upgraded rom to Wanamlites MGA + Adam kernel and I see alot of general improvements as to battery and heating.
Although I am still far from satisfied.
I tried disabling Fast Dormancy using Gokhanmoral app for the S3, but that did not change anything at all. FD still at about 15%+ as it was yesterday with FD Enabled.
My Carrier is 3(SE) which DoES support Fast Dormancy 8.
any advice on the issues, especially the first wakelock which I cant seem to find anything on?!
I found on Nexus 4 this issue but not SGS4.
Sorry to say but I think we will have to wait for a fix from google.. seems the problem is with jelly bean..
I have tried almost all custom roms and using the latest firmware.... but no use..media server still eats too much battery.. there is hardly any deep sleep...
Yea there maybe a few tweaks you may apply using 3rd party softwares to optimize battery at the existing inefficient level....

Think it was MEA or something.
Just realized MGA is also for my region and carrier same as MEA do I doubt it will be different but I'll try later.
Another thing is, could bad reception be a battery drain too?
Cus I've been on holiday past week and connection is between 3g, h+ and no data constantly. Also GSM is constantly no bars to 2 bars.
Could this constant change and bad reception be reason for the msm_hsic_host wakelock?

[EDIT] sorry, I missed that you already tried disabling Fast Dormancy by Gokhanmoral app...
Just wanted to open a thread to see if anyone has optimized the fast drain of the battery with the 1.60 EU rom.
As for me I disabled G now and fixed as seen in other threads wifi on 2.4 ghz and limited connection to 3G (no LTE cause I do not need so big speed in downloading apps when I do not have wifi).
What I noticed is that with kitkat 4.4.3 the ink display was showing 4 days left , while after the update it shows 1 day and an half more or less.
It could be due to some apps I installed. Checked the percentage of use of each app and didn't notice anything strange.
As far as I understood the 1.99 RU rom has battery improvements, but I do not want to flash the phone cause it is always a risk(and I do not want to lose my warranty being the phone brand new).
Any hints on how to improve battery life?
BTW: today my yota apps have received updates through the playstore, so good! Hope to see a 1.99 EU or something similar too soon.
Cheers
Thanks for sharing. I too hope there will be update for EU version, I have never flashed a phone or rooted it.. except for flashing a Nokia 10 years ago that was easy.
I do have issue with erratic battery life on YP - sometimes is shows 5 days on Ink screen with YotaEnergy, sometimes even with YotaEnergy on it would drain in 16-20 hours, phone is hot like an iron. When I run CClearner or Battery Doctor to close apps, it cools down and things go good again for a while till I use the phone again. I checked there are no battery draining apps running, except I noticed Yota Apps Laucher consuming up to 14% battery at any point of time even with YotaEnergy on. I don't even have the Application tile enabled on the Ink display.
So is 1.60 ROM the last version for EU? It looks like I have no choice but go with the RU version if I want to get updates.
Anybody? Me too wondering what is experience from 1.99 regarding battery life...
Do you see any improvements over 1.60?

I checked.
According to forum here the battery life is mixed bag.
http://4pda.ru/forum/index.php?showtopic=550302&st=8200
seems the battery performs better and there should be other improvements. Anyway if you have EU rom, rumors are that an OTA is going to be released soon , so I would suggest to wait for that
