Battery Issue Finally Fixed

I read on another site to simply turn off the always on in the wireless settings (not the background data in the sync menu) and my battery life has at least doubled. I was worried that my e-mail would not download or other apps would not work, but all my email still comes. The trick is that while your phone is in sleep mode it does not look for email, but once you use it the phone will get your email. Unless you MUST get your email right away, I would highly recommend changing this setting. All input would be greatly appreciated, I want to see if my good luck is working for other people. On a side note I am using Fresh ROM 2.0d.

Could you post the specific path to the setting you're talking about?
If I set my wifi to anything other than "never sleep", then once my phone goes into sleep mode I have to follow a long, convoluted, pain in the ass procedure to get wifi to work at all.
Hopefully that's not the setting you're talking about?

I posted this exact same thing in another thread two days ago. I was so stoked on my battery performance that I wanted to tell others. It's incredible the difference it makes! If you want even better performance go into Settings>Location...uncheck the use wireless networks box, and check the use GPS. Believe it or not the GPS uses a lot LESS battery life to detect your location than the wireless networks.
I'm getting like 2 whole days out of my phone now after doing these things...and that's with pretty moderate use. Hope other people try it out too.

where are these options?

I agree, I used the GPS as well, not the use wireless network. I forgot about that one. Your phone will only use the GPS when it needs it, not all the time like we used to think. The exact settings are at MENU/SETTINGS/WIRELESS & NETWORKS/MOBILE NETWORKS\AND UNCHECK ENABLE ALWAYS-ON MOBILE

This will vary from person to person. It will depend A LOT on how good your coverage is in the spot you're currently at.
GPS is GPS. It will require the same amount of juice anywhere on the planet.
Cell chips are different. They are hardcoded to give more electricity to the radio circuit when the signal is weak, for obvious reasons. So if you have a cell tower in your back yard, then yeah, you'll get great battery performance relying on cell based options. If your nearest cell tower is 4 miles away, and you're one of those people that loses signal when you go into your basement, then telling your phone to use cell info is only going to chew up battery even faster....

no thanks. This isn't a fix, it's a pref change.
Fix would mean that everything stays the same and you just get better battery life.
But, good advice none the less, just not for me.

Yeah, people on the forum use the word "fix" WAY too quickly.
"Fix" means everything works like you would expect, and like it should. Around here, people use the word "fix" when what they really mean is "here's a half-assed workaround that's a complete pain in the ass, but it will get 10% of the people by until something better comes along...."....

+1 - 6 minutes and counting to receive a test / text msg, while phone is sleeping. Nice the know though, if I need to really trade connectivity for battery duration. I should test whether sms polling is tied to the email polling interval. Cause it ain't interrupt driven with this setting.
edit: i know it's not really sms polling, but rather the lack of an interrupt(-ion of sleep).

Yes, you are right, it is not a fix, but a great way to increase battery life and like I said, everything works the same. I get messages the exact same way and email will go straight to my phone once I use it.

You sure about that?
When my wife sends me a text, I want to see it 5 seconds later, not 5 minutes later.
That may not matter to you, but when you make a statement to the whole world, you have to realize that some of us care about things that you might not.
How thoroughly did you test before you decided to say "everything works the same"?
Did you really test EVERYTHING? Or did you just test "everything that matters to you"?

I used to turn off background data and stuff on my stock 1.5, and I was thrilled I could actually leave it on with 2.1 so I wouldn't have to wait for google voice texts and gmail to come in. With 2.1 I can go the whole day with moderate usage and still have 40% at least left when I go to bed. Let it charge overnight and I'm good. This is good to know though if I am out in the sticks in a pinch and need the extra battery.

maybe it's different in 2.1 but in 1.5 i tried turning off the "always on" setting under mobile network settings under wireless controls but i found that after a while the phone will fail to restart evdo upon awakening and the only way to fix it is reboot. Never tried it on 2.1 but to me between the time on without signal fix nd upgraded radio i get all the battery life i need...

I get messages right away. I just got another one, tested it with a friend and it came right away!

On a side note, messages and phone calls have nothing to do with the internet. Remember we used to get text messages and phone calls way before smart phones.

But at what cost?
That's the big question here. Are you 100% sure that you're not missing any communications, or having them delayed?
I'd LOVE to have better battery life, but when it comes down to it my phone is a communication tool. If any battery tweaks delay messages, then they're WORSE then useless, they're actually harmful.
If I wanted to use my phone as a half-assed replacement for a PSP, then I'm sure I could squeeze some amazing battery life out of it, too. But above all, and with NO compromise, I must be able to send and receive communications instantly.
That's what a phone is.

Have you rebooted while in that mode?

Yes I have rebooted and just did another test. Got the text right away. Even more interesting is I have a program called Mobile Defense which can find your phone if it is missing and that works as well since it is all done through text messages.

[Q] Cell signal graphic on "CM9 by elginsk8r"

Just wondering if the appearance of the cell network signal is normal (shows its like half full)
I've flashed a few different radios and none seem to get the signal higher than what looks likes about 50% (as measured by the graphic)
Is this just how the graphic appears?
i can't link because i'm new but the picture is at
dl.dropbox.com/u/9195034/signal.png

Are you losing signal or having reception problems?
Be careful flashing radios too often. A bad flash equals a bricked phone.

Same issue. I use WiFi so much I hadn't noticed it. I am able to get full WiFi bars though. Maybe the software isn't coding to report a high signal even when it's available? I'll have to test this again while standing/driving next to a cell tower.

If the signal is reporting the same at all times no matter what, it's probably b/c he forgot to add a line to the build.prop
I spotted this in zips' older builds and he fixed it when I told him what it was and what he needed to do

Care to share with the rest of the class what this line is?
Sent from my HTC Glacier using XDA

I have the same issue. Im guessing its because the build isnt finished yet. Also, do any of you have the wifi calling feature on this rom? When i first got the phone, i can use the wifi calling whenever I am not in range of a signal or something, like in my basement, but now that i flashed my phone I dont have it, and i dont know where to get it from.
Any help would be appreciated

edit system/build.prop and add
ro.telephony.ril.v3=signalstrength
reboot and done

[Q] Strange Wakelocks causing excessive battery drain

I just bought a droid razr m xt907 refurbished off ebay. I'm currently running it on the Telus network up in Canada. Everything works fine, I can receive calls and text messages just fine. My only problem is that whenever I'm connected to Telus or disconnected from all networks, I get three wakelocks that hold the phone awake sucking the battery. If I'm in airplane mode the three wakelocks disappear, the phone can sleep and I get excellent battery life. The wakelocks are called smdcntl0, smdcntl1, and radio-interface. In case it is relevant, I'm on 3G all the time since Telus doesn't run a 2G network. I've tried switching basebands and that didn't change anything, the wakelocks also follow me no matter which rom I use, I get the same wakelocks on stock 4.1.2, on aokp 4.2.2, and on carbon rom. Also, if anyone has a copy of the australian non-hlos.bin, I would like to try that to see if it helps.
If anybody has any suggestions I would greatly appreciate it, thank you.

judging from your 3rd screenshot, looks like your phone is having trouble holding onto a signal.
try a custom kernel.

Flashing aokp (which has a different kernel) really helped with the reception, I've gone from 2/3 bars to a consistent 4, thanks. The phone still won't deep sleep though.

I have same problem on stock since first day i have Razr M.
Many wakelocks when screen is off, but this doesn't drains battery.

get cpuspy and check after a full day. there is also an app called CPU Sleeper which will help.
however, if your battery is not draining, then I would not tweak anything.

here's what I suggest. get the CPUSpy app (free on the market). charge the phone to 100%, refresh the timers in the CPUSpy app (or reboot the phone). then, over the course of the day, check back in the app to see if the phone has hit the deep sleep mode.
if not, then try the Greenify app to hibernate some apps that you suspect could be causing the issue.

They're kernel wakelocks, those aren't caused by apps. They also disappear when I go onto airplane mode so I think it has something to do with the modem. I actually have a log from betterbatterystats showing cpu states, it only deep sleeps for a few minutes if the phone's on all day.

then something's up with your kernel or modem. are you sure you are getting a strong signal? could also very well be the tower in your area (cell or mobile data)
I had some serious battery drainage when I tried to install an updated radio on an older kernel awhile back....

So you did some kind of restore? What did you do exactly?

I ask cause your sw is a mess. Radio is new. Sys is old.
You should have, with that radio:
System Version 98.16.3.XT907.Verizon.en.US.

you can try wiping every thing and just booting any rom or stock.

[Q] ATT Note3 stays awake while on 4g only

Basically as the title says, my note3 is constantly waking up while on 4g. it doesnt stay in a deep sleep. over the last few days i have done some experimenting erasing apps and turning them off and force stopping. i am pretty sure it is the android system itself not a app i have. i barely have any apps installed. i use maildroid, its setup to push and checks only every 6 hours. i use fleksy for a keyboard. and hoverchat for texting. using nova for a launcher, swipe up for swiping up. pretty simple and clean i keep all of the eye tracking nfc stuff like that off just using it as a simple powerful phone to browse the internet and text.
background. i had the kitkat leak that was posted here in jan i loved it becides everything would stop responding constantly. but the battery life was amazing. so i backtracked went to the 4.3 release then did the official update with the instructions on these boards. immediatly i noticed the battery life was less and the phone wasnt staying alseep so i started the troubleshooting. it has been over a week since the update too i know sometimes new roms take a few days to stablize. but it hasnt.
so what would cause a phone to be constantly being woken up while on 4g only? the pics i included show it. the first about half of the 4 hr 38 minute one part of data i am on 4g only. the long bar of being awake at the start and end of the 4g time is me playing music. the only screenshot the first 1/3 is on 4g only. no music only texting and internet didnt use it much today.
thanks for reading

Grab wakelock detector or Better Battery Stats and let it run for a few hours, then post the log if using BBS - and check the wakelocks, it's possible your signal is fluctuating too much and causing the device to constantly seek. But a wake lock monitor will pretty much tell you exactly what it is.

I was under the impression that wakening detection doesn't work with kit kat unless rooted? I use gsam battery app sometimes and it is basically the kernal it seems.
for most of my time with the phone I am in downtown of a major city with amazing 4g when it is doing it

Update
Tried a wipe reset and it worked great tested off and on WiFi. No drain at all when screen was off. Installed apps slowly and tested and all was good. Then I left the phone on the charger overnight woke up and it was back to the being awake often when on 4g only. I am stumped any new idea's?

Read up and figured out that its the customer. Xml file It is turned to on I tried editing it but cannot save it because it is protected file I guess. Any other way to save it?

Seems to be the bam_dmux_wakelock I googled it seems to be only when not on WiFi which is my issue. Just gotta figure out the rest

Anyone know how to edit that customer. Xml file? Fast dormacy and the bam_dmux_wakelock seem to go hand in hand. Phone was all over the place today I have 47 minutes of that wakelock with about 6 hours of off WiFi time so it's a decent drain

[XPOSED] Mobile Radio Active Fix now available via xposed module

Article about the bug: http://www.xda-developers.com/xposed-module-to-fix-mobileradioactive-bug/
Details here:
http://forum.xda-developers.com/note-4/general/xposed-mobile-radio-active-fix-t3137573
This should be considered a must have along with the Lollipop memory leak fix xposed module for anyone rooted even if they don't use any other xposed modules*.
This should noticeably improve battery life.
* Rootcloak is also useful to idol users because it allows system update checker to CHECK for updates without the "root detected" error. You should still not actually INSTALL updates until fully unrooted.

Thanks for the info Famewolf !
I've been closely following the thread but it seems this only fix the wrong reporting of mobile radio in the battery stats and only improve a little the battery life.
Still better than nothing tough.
I'm astonished this huge bug is only looked into by xda volunteers and not by Google...
Bazoocaze did an amazing job btw !

It's more than just "reporting". It's the equivalent of opening the door to your garage or outside in the middle of summer and then wondering where all your cool air conditioning is going. Check your power bill the next month when in this analogy you would have left the door open for hours and hours at a time.
It fixes a bug that dropped the instruction telling it to close the radio so the radio connection remained open using up battery needlessly. I do however agree that it is sad Google and others didn't fix this a long while back as it's been widely reported.

Then you have somehow magically fixed a known bug in all versions of Lollipop.

I have a 6039S with no sim card installed, and it still shows "Cell standby" using a few percentage of power. Is this a bug, and is it the same as the Mobile Radio Active bug?

You might ask in the actual radio fix thread linked in the message I linked to as they can better provide you details but it's a given that if you have not patched the bug then you still HAVE the bug.

So, does it actually work?

I think Radio active bug is not present in this phone, i have been all day on LTE and Radio active time shows 2 hours. which is more or less the screen on time, and the phone was 12 more hours in my pocket or on my desk.

Multiple people on the forum have reported they had to put their phone into wcdma mode to stop excessive battery drainage. You are free to believe as you wish. See previous posts and the thread related to the bug as it's not my job to convince you.

have used Xposed with this module and with the memory fix module for 5.0.x firmware for two weeks, but didnt notice any noticable battery improvements or less lagging,so i deleted all modules and xposed.

I don't have this bug too. Maybe it's on some carrier or some lte frequencies... report thing is easy but send logs or open a real thread about that is difficult for you Famewolf and you don't even know or you can't prove if the module do something on this phone execpt a placebo in the battery stats... So please stop send stroll people because their device work or have not the same bug or problem of yours .... (by the way i think the governor of the cpu is catastrophic and it can be better with a little bit of tweaking) Bye

hey guys now I can't permanently keep the data to " wcdma only" by going in phone testing (*#*#4636#*#*) remember that?
perhaps it is because of the "mobile active radio fix"
Xposed module because it was working fine earlier but even though now I have tried disabling module and uninstalling module but I can't change it to wcdma only, it keeps fixed on gsm only.
even though in setting I have it set to 3g preferred but because of poor reception many time it goes to 2g and back to 3g it is very irritating.
btw I am able to use 3g, can anyhody tell me how to fix that with fixing of mobile radio active bug

I use wcdma only mode all the time as i'm in a fringe area that barely has 3g in both stock and now in cm12.1....the radiofix module wouldn't have anything to do with it. You can go into the dialer and do a *#*#4636#*#* then go into phone info which will let you select wcdma only or you can install the "network" app from either google play or f-droid which when ran acts as a shortcut to take you straight to the phone info screen so you can set wcdma only.

You can go into the dialer and do a *#*#4636#*#* then go into phone info which will let you select wcdma only or you can install the "network" app from either google play or f-droid which when ran acts as a shortcut to take you straight to the phone info screen so you can set wcdma only.

I tried both it doesn't seem to stick to anything other than gsm only.
though my 3g works, weird
