[Q] Cell Standby/Time without signal 100% - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

So I have been checking my battery usage over the last few weeks, and under Cell Standby tab my "time without signal" is always 100% . Im not sure if this is draing the battery or if its just a typo/bug, but should I be alarmed? Is there anyway I can fix it? I am on Rocket v18 right now with Abyss 3.1 kernel but this problem is spread across all custom roms I have run. Any help?

My phone shares that as well. I have noticed no effect on my battery. I am also running rocketrom v18 and speedmod kernal

[Q] Firebird 2-0.8 and wifi bettery drain fix.

Can we use update-wifi-xxjpy.zip, which suppose to fix wifi bettery drain issue, with Firebird 2-0.8?
I am running perception ROM, Firebird 2-0.8, and JL2 modem. I notice that, wifi would take a lot of battry life. If I turn wifi off, the bettery level is almost not changed. I did research and lead me to this post
http://forum.xda-developers.com/showpost.php?p=10056736&postcount=6706
which have the new wifi firmware. The post mentions update kernel, but really
not specific. I am not sure that the wifi firmware would work with FB.
Thanks.
I found this post. It's very helpful.

you might wanna just try and reflash the kernel because i get awesome battery with firebird along with most others
yes,I did try, and I am please with the result. Last night, I flash new wifi farmware, and leave the phone idle. I lose 1% overnight. So, it's work. and +1 on battery life of FB.

Holy frick! 1 % over night ! Try 10% ? That's what I lose over night, everything off besides network.. Firefly+ Firebird+JL4 ... tried many a rom and modem and longest i;ve made it with small usage and few texts is 10 hours , hardly any usage.. Not sure what is up. Hating it.

I had a similar experience with the Firebird 2 kernel also. My battery would be drained before my 6:00am alarm would go off. Ever since going to the Speedmod kernel, I get around 22-24 hours of battery life. I believe my phone just jives better with Speedmod.
where can I find JL2 modem? (one that I can install using rom manager)
There are several modem threads over in the development forum. They have links to most of the modem updates. This one has the JL2 modem.

[Q] Darkys 9.5 Wlan causes Battery Drain

Hey guys,
the day before yesterday i flashed Darky's 9.5 on my phone.
This is the first Darkys version for me. The flashing was fine and very easy but then i got big problem regarding the Wlan battery use.
First i tell you how i flashed Darkys, perhaps i did a failure here.
1) First i flashed Darkys Reserrection Version on my phone
2) After that i configured the Darkys App from the market and flashed the reserrection.zip with CWM
3) At the end i flashed Darky's 9.5 with CWM
Now the points regarding my problem.
Yesterday night i switch off my phone with at least 85% battery. I switched off GPS,Bluetooth and i deactivated the data transfer mode for UMTS. But it was my intention to test the battery drain with active WLAN, because with the original T-Mobile Firmware the phone uses circa 25% battery a night.
But when i woke up i was really shocked. My phone turned off and the battery was complete empty. In this night the battery drained 85%. How is this possible? There were no apps running excepting the Advanced Task Killer.
Did i something wrong? (When i flashed the battery was fully charged)!!
//edit
Here are my settings:
PDA: I9000XWJS8
Phone: I9000XXJVE
CSC: I9000XXJS1
Kernel: DarkCore 1.0
I wouldn't think this was a common issue. Have you tried just re-flashing the ROM again via CWM? Maybe try the same thing again?
Thx for your answer.
Yeah i even think that it's not a common issue.
I will watch the battery this night. If the bug occurs again, i will flash the Rom with CWM again. Have i to disable the lagfix or can i do it on the fly without changing something in the current system ? If yes, where?
my battery is the best its been in a long while since using this rom so i wouldnt dismiss it just yet. what modem are u using?
I use the modem Darky's App Configurator has recommend (JQ1 but i have read that JVE is flashed (se my settings above)). But i think I will try flashing again. This night the battery drops from 100% to 47% with the same settings I mentioned above. Then i watched the battery usage, but they were strange.
Wifi and "Wifi using" uses 100% cause they were running the whole time. But the category "execution" used 75%, so the phone did not drop into sleep mode for about 75% of the whole night? How is this possible? I checked all my 3rd party apps I installed on my own and they don't have a setting to manage this.
Does one app of Darky's Configurator do this?
Well Darky can answer question best .
Me i blame the rom change the rom .
jje
Now i flashed Darkys 9.5 with wipe again.I will watch the battery drain and I will notify you about the result.
//edit
Now I go asleep and I will report tomorrow if the flash was successfull. But I got one question left:
By accident I saw in the wireless setting window that my phone scans every 5 seconds for new devices, even if its connected to my own router. (If the phone goes to standby the WLAN does not scan cause of my settings). But why das it scan every 5 or 6 seconds, even if it's connected to my own device?? Is it possible to increment the scan time?
Good morning guys,
here is my update:
I think the reflash worked. Last night my phone uses 10% battery with wifi and data transfer on, gps and bluetooth off. I think this is a good value.
By using the flightmode the next times I will save some more
Now there is the question left regarding the number of wifi scanns. (see the post above). Is it modifiable ?

If you don't mind me asking: what modem do you use? And how long does your battery usually last for?
Thanks

Did you recalibrate your battery after upgrading to Darky's 9.5?
It is recommended that u recalibrate your battery when you flash a new ROM.
You shoukd recalibrate your battery, i.e. drain it, turn off your phone and fully charge it, completely drain it (use it heavily). Then charge it again and voila, recalibrated!
Also, I find that after flashing a new ROM the battery drains really quick the first 2 times I charge it, before actually working as it should. So it's not that strange that your phones battery was dead in the morning. But I think this also has to do with recalibrating the battery.
Darkys v9.5 has a battery life of 3-4 days for me (not heavy usage) so it should be better after recalibrating your battery!

What is causing battery to drain?

I have a rooted note with CheckROM v6 that I flashed yesterday running CF-Kernel. Did a full charge yesterday night and I have noticed that my battery is draining rather quickly. Its been 3 hours since I've unplugged my phone and its been awake fully. I have screenshots from Better Batterystats. Can someone help me as to what is causing this drain? Attaching screenshots for reference.

Sorry. Looks like it didnt get uploaded when I attached it from the XDA app
I guess its a Kernel issue. flash different kernel.
Try shutting down as many apps as u can .. lower screen brightness and flash a different kernel. Also use easy battery saver. It really helps when ur battery level is low and u can't charge it immediately. Also see if its a problem with the rom.

Looks like your phone is not going to sleep at all. I read that this could be related to your wireless router - if you are at home it may be trying to constantly talk with your phone which is keeping it on. Try turning off wi-fi and see if the phone goes to sleep for a while. If that works then search for your wireless router in the forums - may show up what else needs to be done to configure it so the problem can be resolved.
The problem still exists even though my router has been switched off. Its been 9 hours and its still fully awake. As to flashing kernel, I flashed CF Kernel from Kitchen Pro. How do I go back to stock kernel that comes with CheckROM. I have tried closing all apps. Nothing much is open. Betterbatterystats stil shows *wifi* android system as running for 9 hours in partial wakelock. Also my screen brightness is set to 40% using ScreenFilter. I run screen filter 24*7
EDIT:I have noticed that this has been happening only after installing CF-Kernel. How do I get back to stock kernel thht comes with checkrom. I flashed CF using KitchenPro

Okay no one seems to have replied but I think the issue is resolved for now. After the battery came down to like 15% after 11 odd hours put the phone for charge. Came back and checked battery usage after like 30 odd mins and battery usage showed that the phone had not been awake for the time it was charged. Then I plugged it out once it was fully charged and the phone started behaving normally. Cheers!

Battery drain after LRK update ? (+ downgrading)

Is it easy to roll back to the previous LRG update as the battery seems to drain pretty fast on this firmware, LRG was pretty much perfect for me as I'd lose 3-4% battery overnight from a full charge but this has lost 15% in the same amount of time.
18hrs since fully charged
76% left (24% gone in 18hrs)
7mins screen time
Deep sleep for 16hrs
It's funny your getting this issue as I have the exact opposite experience with what your getting at. I was with stock Open Germany LRG before, and using that firmware.. I lost about 17% drain after a full charge overnight using it. When I changed Rom to LRK (and installing the latest speedmod kernel), now my phone's overnight battery % goes 1% every 4 hrs.. not bad right? I think you can try exploring other options like flashing kernels first (try speedmod) and see if there's some considerable differences (or not) with your phone's batt life.
Which way did you use to get LRK? On which kernel are you? Which ROM? Do you notice other bugs? (apps that freeze, wifi/gps not working...)
It seems that you have the deep sleep issue, but what's surprizing is that you get it by upgrading... ^^'

hmm, what's special about the speedmod kernel and is it at all risky to flash it ?

Flashed via mobile odin, the kernel is as follows 3.0.15-N7000XXLRK-CL811902. I haven't noticed any bugs thus far. Seems to go into deep sleep according cpuspy

The changelog and functions of speedmod are here : http://touristinparadise.blogspot.sg/2012/01/samsung-galaxy-note-speedmod-kernel.html
I really recommend it, it feels really smooth, and drains less battery imho. And CWM and superuser are included.
All flashes have a risk (but it's minimal), this kernel is known to be safe (you can wipe data/factory reset = MMC superbrick-proof)
In battery settings, what drains the most your battery?

High battery drain while using WI-FI.

Hello.
I recently flashed my P970 with Mackay Rom (Android 4.2.2). It's a little laggy sometimes, but mostly it works well.
There is only one thing that bothers me and that's a high battery drain while using 3G and WI-FI, espiecially WI-FI.
Currently I am using 2G and that works for me (I can turn on 3G while I need) but I have to turn off WI-FI while not using phone because it's draining whole battery only for one night. When I was on stock I had permanetnly turned on WI-FI and battery drain wasn't so high.
It's only because of 4.2.2 on this phone or it's something with this ROM?
I wanted to post in official Mackay ROM thread, but I don't have enough posts to do it.
Thanks in advice.

May be a 4.2.2 issue, I always have 3G enabled (Wifi sometimes) and battery drain is ok. Using Marvel V11 (4.0.4)
If you'd noticed, or if you didnt, check your dBm and then, note it. Also, mackay may not have WLAN tweaked, so the module for WLAN may be stock and should be draining quite quickly. So take note of that
