Hey guys,
I have been trying to solve this on my own for two days now, but I would like to consult the forum now.
So, I was running Pink Sense 1.8 for about 2 weeks with setCPU profiles and was getting satisfactory battery life. I had re-calibrated the battery info maybe 2 weeks before flashing the Pinky ROM (as described here: http://forum.xda-developers.com/showthread.php?t=755903).
All of a sudden, without any app installation or change to either the ROM or software/hardware settings I started getting horrible battery life. The battery would drain completely for less than 6 hours with GPS, 3G, and WiFi off.
*Another strange thing (which I don't know if it was related to my battery issue or not) was that when I would plug the charger it would turn the screen on but switch to the default clock app instead of the HTC sense homescreen. If I pressed home or back it would disappear. This would happen randomly and not always.
So, I figured it's time to jump ROMs and I decided on LeeDroid. I wiped cache, etc. and flashed the ROM. Out of the box the battery life was again pretty crappy (the battery was virtually disappearing in front of my eyes). I found some threads where it was suggested to disable market notifications and that slowed the battery drain a bit but it's still crappy.
I just charged it fully, 3G and WiFi off, and was with the screen off for 99% of the time and it still drained 18% battery in 1hour and 25 mins.
So, my question is - what the hell is going on???
Should I wipe battery info? Should I install a non-WiFi n rom? What more can I do?
I would really appreciate help and advice.
p.s. I am running the latest radio too.
wich radio have you the .23 drains the batery with my desire try with the .30_2
the battery life is better.
did you try reboot your phone maybe your optical joystick dead and drain your battery.
load any new apps recently?

As I said, the problem appeared with absolutely no new apps installed and persists after flashing a new ROM.
How do I know if my optical joystick is dead? It still works if that's what you mean (although I don't like using it).
I will try flashing the 30_2 radio, thanks for that suggestion.

If it works he's not dead
after flashing your radio and if the battery still drain check if the rom you use has his own rules for the cpu freq. if you are in that case don't use cpufreq or something like that because of conflicts.

Thanks, I just flashed the 17_2 radio. It doesn't look like LeeDroid has any requirements for cpu frequencies. I will post an update after an hour.

There seems to be no change with 17_2 radio. 15% drop for 1h45m. I will go through a charge/recharge cycle and if nothing has changed I will flash the 30_2 radio.
Some people had the same effect. It happens when you flash your ROM while the phone is connected to power/charging. The battery stats simply get messed up.
An easy indication for this is if you charge the phone fully while powered on, LED is green, as soon as you unplug the charger the battery drops to some 90%.
The fix is easy too. If the phone is fully "charged" while on, disconnect the charger and switch it off. Then plug the charger in again. The LED should turn orange again and the remaining percentage will be charged. Wait until you have a green LED and your problems are hopefully gone.
Look out for the battery calibrating thread here for more info.
Hope that helps...

Thanks for the suggestions. I always thought it would be better to flash with the ac adapter plugged.
I have tried the method you described above but it hasn't really solved any of the problems.
The battery drain is now at least manageable - i had 50% drop while sleeping for 6 hours (at least it didn't drain it completely). I am going to flash the 30_2 radio and try again.

If you have access to a spare battery, maybe you can try that too?
Normally when I have unexplained problems with the phone, the last drastic step I would take is to wipe everything, data/app/cache. Do a nandroid backup first so that if that doesn't solve your problem you could always get back all your setups.
You could also try Titanium to help save your setup. But I would be careful with what I restore. The last thing I would want is to get the messed up setting back in.
I have noticed also whenever I flash a new rom, the battery seems to get worse. So I would always do a recalibration. The proper step is here:
http://forum.xda-developers.com/showthread.php?t=755903 (and wipe the battery status on the last power up before using).
Lastly, I would use as stock as possible first to see if it is things that I introduce that cause the problem.

I think I can definitely confirm the radio is the problem. There is barely any battery drain in airplane mode (1% drain per hour with WiFi on). I am back to 32.43.00.32U_5.09.00.20 but it seems to drain battery faster than before.
Now that I think back, this battery problem started when i switched to the newer 32.47.00.32U_5.10.05.23 radio. No matter what I do now though even after rolling back to older radios it's still a problem. Damn it.

Ok, I have awesome news! Thanks to user "lenik" on modaco forums I got some extra RIL settings (radio settings) he found for Softbank (my cellphone company here in Japan). Here are the settings:
ro.ril.enable.a52=0
ro.ril.enable.a53=1
ro.ril.fast.dormancy.timeout=3
ro.ril.enable.sbm.feature=1
He said the first two should be found on most ROMs, while the last two are probably carrier specific for SoftBank. Anyways, I just downloaded the latest LeeDroid ROM, modified /system/build.prop file (none of the above settings were in there) to include the above settings and ... got a 5% drop in battery for 10 hours on standby (wifi off, setCPU set to 245Mhz when screen is off). This is unbelievable.
Anyways, here are lenik's blog posts about it:

VERY nice results! Do you think that these RIL settings should work on any network/carrier?
It's very odd because today I noticed my battery performance dropping large, BUT before it was always great. I am also on LeeDrOiD 2.1, and while at home, with WiFi + BT on AND connected to my router + handsfree, I lose only about 3-4% an hour.
Today when I left the house and went shopping, I was in the store for 1.5 hrs and I had lost near 15%! I had even turned off Wifi so it wasn't trying to scan APs. Very very strange...
Anyways, I want to maybe try these RIL settings if it will work on any carrier. Does anyone know if I can edit build.prop while in recovery, or do I have to edit it in the ROM .zip then reflash the entire ROM?
Thanks for the post and hunting down a solution slyn4ice, I'm glad that it has helped you out big time!
*** EDIT *** - After looking more into my JuicePlotter graphs, I notice that the battery life gets killed when I am using APN / 3G / HSPA network. I would have thought Wifi would take more power, but that seems not to be so. I DID have "Network Mode" set to "WCDMA only" (in Mobile Network Settings) because I heard it might save battery not having to switch back and forth from EDGE to 3G, but I guess that didn't help...I've since switched it back, but need a lot of charging before I can test again.
Does anyone else notice that when they're on 3G/H the battery drops MUCH quicker than if you were connected to Wifi instead? This is just my last hurdle towards a PERFECT ROM!
Thanks in advance all!
3G uses waaay more power than WiFi. After all, the data usually travels long distances and needs to be amplified. This effect is pronounced especially if in the limit zones of 2G/3G coverage and you have 3G preferred, the phone boosts the power to maximum to maintain 3G.
Gsm Auto (PRL) prefers 2G if 3G coverage is too low. WCDMA Preferred tries to maintain 3G connection even if it means sacrificing battery life.
If you are constantly in good coverage zones, no problem, but to the people living on the edges of proper 3G coverage it meas a big hit to battery life, especially if the mobile data is used. This partly explains why some get superb battery life and others far worse.

Amazing explanation and reaffirmation of my thoughts Jgruar (JuicePlotter confirms it). I guess from my old WinMo days, I always remember Wifi being the power hog. I actually did change it back to GSM/Auto since that was the only change I made lately, but I thought I'd chime in while my device was charging back up, hoping for a reply just like that!
Thanks a bunch!

From what I understand you need to update RIL settings in the ROM and then flash the modified ROM. I just edited the /system/build.prop file in the Leedriod zip file and saved (didn't resign or anything). Flashed the ROM through ROM Manager recovery (I also tried flashing it through the normal recovery but it failed on the "verifying image" stage - I guess because I didn't resign the archive).
As far as the options themselves - only the last two should be carrier specific. I haven't researched anything about them, so I have absolutely no idea what they actually do. "lenik" just copied them from an official Softbank ROM.
God, i just checked JuicePlotter and i dropped 1% for 1h10m (everything off except the radio + setCPU to ~400Mhz when screen off). This is just crazy ... awesome ))))
Is the setting rom specific, or will it work om opendesire?

hey guys...
i have tried everything to stop the battery drain
switched to many different roms
under-clocked processor to 768mhz
set a black wallpaper
brightness set to minimal
did battery calibration
switched of all background processes and made sure no location seeking programs works.
used CPU spy, the cell does go to deep sleep
tried juice defender and deep sleep battery saver
but nothing seemed to work
phone locked on full charge drains 40 to 50% in night without using.
then after a few days later i restored everything and opened airplane mode and I went to sleep, in the morning the battery didn't went low a single percent. battery health is good as works really well on airplane mode.
i have low signal issues but i get text msgs and calls with no problems at all, and my explorer and s3 seems to perform well
my all type pf connectivity is off example: location access WiFi Bluetooth etc only gsm is working, i manually selected the network and set it to gsm only rather them auto from *#*#4636#*#*.
what shall i do??
i searched and tried many things from the internet.
i really want those calls i cant always be on airplane mode, the problem is 200% of the antenna draining juice to get more signals. please help.
is there any way to stop the battery drain or restricting the antenna to consume less juice?
PS:using cm10.1 by nightly version:19 Aug 13.
anyone??
one thing more i installed better battery stats it says
no or unknown signal
no data connection
and it is running continuously like since i installed betterbatterystats.
where can i get this bug?? or disable this service??
please give a detailed explanation.
There are a few good apps to try I use
battery mix (I think this is one of the best) and wakelock detector both from my the market.

bro if ics solves the problem of battery drain due to low signal then y not... i will surely try...
i dont get a single percent drain on airplane mode the problem is surely network sucking it down... yesterday it went 100% to 48% in 8 hours in deep sleep n no wakelocks[betterbatterystats] :crying:
guys it is to update you i have just updated the latest radio for desire hd from
here: http://www.icsforums.com/forum/showthread/26951
from version:12.54.60.25P_26.09.04.11_M2
to:12.69.60.29_26.17.14.11_M
i will use it for a while and will let u know its results.
thank you for all your support.
well the radio update did improve the battry a little
now it drains 40% instead of 50% but still its not enough.
can somebody tell me how to control the modem to not search for signals that rapaidly.
Battery drain
I´m having same problems with my DHD, currently im using 4.2.2 Samsation (was it named like that but anyways 4.2.2). Without using phone it still drains 40% in few hours.. I got replacement battery from eBay and thought that would help but didnt help at all. I´ve tried different roms but would like to have newest roms without battery draining so much, so could someone share how to get it better?
And about changing radio, was there a possibility that you may brick ur device if installing wrong radio?
Thanks already!

as i mentioned bro the problem is purely regarding the network sucking down the battery my bluetooth gps wfi everything is turned off... i use 2g gsm only... if u put ur cell in airplane mode the battery doesnt goes down by a single percent. its gsm standyby sucking the battery.
and regarding the radio if u do it right and reasearch a little u wont brick it for sure. got my radio from here:http://www.icsforums.com/forum/showthread/26951
downloaded this zip and replaced the radio.img within the zip from above link.

put the file on sd card root
booted in bootloader
that did the job.

yup there was nothing, no wakelocks etc i even underclocked my processor to 768mhz... the thing is the signal reception cause when i turn the cell in airplane mode and leave it over night the battery doesnt goes down a single percent. it acts solid.
i get around 18 asu signals at my place i check it from *#*#4636#*#*
but the thing is i was using an HTC explorer before switching to desire hd and with the gsm mode(no airplane mode) the battry stayed solid like the desire hd one with airplane mode(didnt dropped a single percent) at the same house same place.
dont know what going on.
Hi guys
I have a LTE Note II and have had this battery drain on standby where wifi will absolutely destroy my battery. This has been going on for months and months and I'm just not sure if Samsung are ever going to resolve this and it is quite the pain in the arse.
I've done many tweaks to my phone, and all location services are off. Also, I've set it as a static IP, but nothing seems to help. I think this is related to the wlan_rx_wake wakelock? I get the impression my phone is responding to the wifi and getting woken up constantly.
Does anyone else experience this and do you have any suggestions?
P.S. please don't mention my apps causing it. It definitely is not. I know my way around Android and also, my Nexus 4 with the same setup (but location + google now turned ON) absolutely annihilates my Note II battery life on standby. This is clearly a Samsung problem that they have ignored for the best part of a whole year, and it seems to be related to wifi.
Any help would be greatly appreciated.
Thanks

No exact figures but I have been observing it for months now and it hasn't been the case with any other phone I use. With wifi on, it'll drain around 20% overnight. With Wifi off, it'll drain 5 or so %. With Wifi on on every other phone I own/owned, it will barely drain at all overnight.

That's not bad, it improves battery usage. I don't recognize your problem. Does the phone go into deep sleep with wifi on? Which rom do you use?

Stock ROM. And yeah, but it is constantly being woken up.
Sorry for the bump, but this hasn't changed.
I'm not sure if this is to do with just the N7105, but it is something that just won't go away. I'm now finding I lose between 20 and 30% overnight (around 7 hours) with wifi on, or about 10% with data on. With these both turned off but the phone radio still being on, it only drops about 2% in the same time. This was tested with bluetooth/gps and sync turned off.
I don't really have the time to write up everything that I have tried, but suffice to say I have tweaked the phone a lot over the past few months trying to sort this out, but nothing works.
Here is a quick summary of the stuff I have done.
Firstly, I have to run a stock rom and kernel because there is an app I need that will not work on custom roms/kernels. It also doesn't work on root but I have found a procedure to toggle unroot/root when need be and it works fine. Therefore I'm stuck on 4.1.2 as I want to be rooted but I cannot use any custom rom or kernels.
I have tried factory wiping the phone/installing later versions of 4.1.2, etc etc and the same problems still exists with a freshly wiped phone and no apps installed. This problem also doesn't happen with my Nexus 4 or any other phone I have owned with the same setup, so I am very certain it is not due to a misbehaving app.
I have frozen a lot of bloat with titanium backup, I have hibernated a hell of a lot of stuff with greenify (including system app where there are no perceivable negative consequences)
I have added a few tweaks to the build.prop such as to disable fast dormancy and a few other supposed power saving ones which are meant to help with the msm_hsic wakelock.
There are many other things such as setting a static IP, and also tweaking with my router based on some advise I found on these forums. Nothing much has helped.
Location services and google now are off, and I'm not using the Samsung bloatware apps.
I use betterbatterystats and the partial wakelocks are fine. Very low infact.
However, IMO it is two "kernal wakelocks" which are causing me the problem.
wlan_rx_wake - in regards to the wifi
mdm_hsic_pm0 - in regards to the data
These are by no means outrageously high. My estimation is perhaps 10 mins wake up time and around 2000 "expire time" (whatever that means) every 3 hours or so. However, these two are always the highest kernel wakelock depending on if i'm using wifi (wlan_rx_wake) or data (mdm_hsic_pm0). My phone is also not being kept awake too long too in general.. at a guess around 3 hours awake time for every 2 hours screen on time for every 15-20 hours.
I can't remember if these kernel wakelocks were super duper high in the past, and the fixes I tried actually lowered them, but I still notice this massive Idle drain when on data or wifi (just over 1% per hour - or 2-3% per hour respectively).
In regards to the Wifi.. I suspect that packets are being sent from my router which are constantly waking up my phone. Unfortunately, I haven't been able to solve this problem with any of the router-side fixes I've tried.
This leads me to suspect that the wifi and data radio of the N7105 is power hungry, or I've had a faulty unit since day one. I keep hearing about this stellar battery life for this phone but, for me, the best I've ever got is around 20 hours. This may sound good but the problem is it is 20 hours with 6 hours screen on time, or 20 hours with 2 hours screen on time. This doesn't seem to make a difference where I should be getting two days when I only have 2 hours screen on time.
Any help would be greatly appreciated, and any experiances of others with the N7105 may help find out if it indeed is more power hungry. I'd also like to add that my network does not support 4G yet so this is all on 3G and NOT LTE.
Thank you, and sorry for such a long post.

I have a LTE Note II and have had this battery drain on standby where wifi will absolutely destroy my battery. This has been going on for months and months and I'm just not sure if Samsung are ever going to resolve this and it is quite the pain in the arse.
I've done many tweaks to my phone, and all location services are off. Also, I've set it as a static IP, but nothing seems to help. I think this is related to the wlan_rx_wake wakelock? I get the impression my phone is responding to the wifi and getting woken up constantly.
Does anyone else experience this and do you have any suggestions?
P.S. please don't mention my apps causing it. It definitely is not. I know my way around Android and also, my Nexus 4 with the same setup (but location + google now turned ON) absolutely annihilates my Note II battery life on standby. This is clearly a Samsung problem that they have ignored for the best part of a whole year, and it seems to be related to wifi.
Any help would be greatly appreciated.
Thanks

I ain't expert...
but, I would suggest like this :
Go to wifi, press menu and then Advanced (advanced setting of the wifi).
uncheck/untick "Scanning always available"
"Keep wifi on during sleep" = set to Never.
uncheck / untick "auto network switch btwen wifi network and mobile networks"
all these helps me to minimize the usage of wifi during night times (when I sleep). Anyway, device also need to have a deepsleep
Hope can help you as well.

Hi, I have S-ON with CM11 and few problems i cant live with.
Firstly, i have bad wi-fi signal, coin trick not working. But like, i have a signal, like 2 bars, but internet not work and I must restart wifi to work.
Second problem is with audio, sometimes, after call or whenever its so fast, so i must restart phone to work normal (normally 2x per day )
And sometimes it crashes in Google Camera, when i micro to something in fast.
And battery life is so horrible too, after 20 minutes from 100% i have 88%, it's that same with you? Im thinking about buying OneX+ battery..
Can somebody help me? Thanks guys!

Install other rom near to sense this is know problems with kitkat roms try other kitkat rom and see if this fix the problems
As my title suggests, the phone was working fine until a few days ago (the battery drops by 1% at every 2 hours normally), when it suddenly started dropping by 4% each hour.
I tried everything I could think of: restarted the phone, wiped storage cache, formatted recovery cache, checked for drain applications, turned it off and charged it like that and left it there for a few hours, restored google play to factory settings and updated it again (first tried to reset google play services just to make sure that isn't the problem, but the phone wouldn't let me). I have no idea what to try anymore.
Anyone has any idea regarding this?
Please provide more details, what firmware are you on? Which ROM are you using if any?

I'm using WW firmware .184 (the problem started while i was still on .183 though) and I'm still on stock ROM, unrooted (and never rooted it).
Everything was working fine until a few days ago...

Could you please post a screenshot of your battery usage? And please try using a different charger. I've noticed that my phone gives me more battery power on a low voltage charger.

I will do so when I'll have the chance, I recharged the phone overnight and I unplugged it 2 hours ago. I tested these days all kind of different networks (2G/3G/4G) and WiFi on and off. I left the phone with Wi-Fi off and only 2G. Now when I checked it after 2 hours, I see that it's at 99%, as it's supposed to be normally, 1% per 2 hours discharge. Now I've re-enabled WiFi and I'll see if it starts dropping as fast as before or not. After that I'll re-enable 3G (that's on what I'm usually using my phone) and turn Wi-Fi off and see if it starts dropping normally. I wanna see if for one reason or another, Wi-Fi might be the issue.
Normally,the phone drops 1% per 2 hours with 3G and Wi-Fi enabled.
If this I won't get any result or conclusion from this, then I'll post a screenshot.
Once try safemod.

Okay so it really seems that Wi-Fi might be the issue. While my phone had Wi-Fi on and 2G, it dropped like crazy again. After i disabled Wi-Fi, I also moved the phone back to 3G and there was only 2% drain in like 6 hours. Now I re-enabled the Wi-Fi and trying again...but it seems that indeed Wi-Fi is consuming the battery for an unknown reasons. I've always kept Wi-Fi on before and it didn't drain battery.

It's off
And after leaving Wi-Fi on and getting a huge battery drain...and after a while turning it off and the drain stopping, I can confirm that the problem is somehow Wi-Fi related.
Screenshots attached.
As you can see, when Wi-Fi was on, the battery drained faster, when it was off, it went down a lot slower. The cell networks doesn't look too good but I can confirm that on 2G, where I have green cell network in the battery usage, with Wi-Fi enabled, it drops at the same rate.
