[Q] help: 3G module consumes more power than the WIFI - Xperia Arc Q&A, Help & Troubleshooting

sorry to be repeating this post but I tried it with another rom, cleaned everything and did a "clean" installation and continue with the same problem: if I have WiFi turned on everything works fine but if I turn off and the phone and starts working on 3G battery drain very fast, as you can see in the screenshot so I turn on WIFI again, back to stabilize ... not need to be connected to any network, just the fact that is on (WIFI) everything back to work normally ...
Last rom: ICS Fire_Bird ROM v3.0
kernel: DooMLoRD

from what i know, 3g consumes more power than wifi.
i have the same problem when 3g is on.

yes but the problem is not only that, if the WIFI is on, but no network in range, starts working on 3G, without excessive consumption of battery ... I do not understand what is happening ...

magic wifi

i seem to have an issue with wifi as of late, i do often use at home to save battery, but after being turned off, it has a habit of coming back on by itself randomly...i am currently on universe rom 2.3 which does have the better wifi lock, but i do disable this when at work where i can only recieve a weak 3g signal at best. when i check to see whats quickly discharging the battery, its due to wifi scanning for signal & my 3g on at same time.....

[Q] Wifi never turns off/sleeps T989 CM10 Dec05 nightlym latest BB

I can't say exactly when I noticed this, but it was at least since the CM10 stable, and I've tried a couple nightlies since then. Wifi never seems to turn off according to the battery chart, which I believe because I get somewhat worse battery life now. Had anyone else seen this, or have any suggestions?
Turn off WiFi when not needed. Also, WiFi can save your battery vs a weak signal

Well, I'm doing that manually now, but that's not a solution to the fact that it never goes into standby mode when not associated with an AP.
did you go into settings--wifi--menu--advanced and select keep wifi on during sleep only when plugged in?

No. I prefer it to stay on wifi when there's good signal, so I have only use good wifi connections set, but not to put wifi to sleep. Regardless of that, wifi should be in standby mode when not actively associated with an AP, such as when in the car or anywhere you haven't told it to remember the APs around you.

Wi-Fi turns off when phone in deep sleep

Hi, I saw many posts related to this topic Wi-Fi turns off when phone in deep sleep but not able to find a single working solution.
My phone runs on 4.2.1 with wi-fi sleep policy set to NEVER ( that means always on ideally ) , and tried turning on / off wifi optimization, avoid poor connections is not ticked.
Even after doing everything the wifi is turned off after sometime and when i turn on Screen it turns it back! How to do I solve this?? I am using STOCK rom, with just root.. No other battery saver etc. app installed.

well i have this problem too on every jelly bean rom. the only rom without this problem in cm10 stable. now i'm with cm10.1 hoping they'll fix it like in cm10.
when that problem comes out just toggle on and off airplane mode and it should disappear until next wifi toggle off and on.
I hope google will solve it in key lime pie
CM 10.1 has only just started doing this in the last week or so, it was fine before. Was wondering if it was just me with this issue or not...

Am i correct in understanding that you don't want it to disconnect? The option in the settings is "Keep wifi on during sleep". If you have it at Never, then it will disconnect when the phone goes into sleep. It should be placed on Always because you want it to be on even during sleep
Flowed and Tapped from my Nexus
fixed the wifi problem
Heya! My first post!!!
So, i had the same problem on my Allview P5 Quad.
The guys from Allview released an update for my phone based on 4.2.1 and i thought the problem was from them. I had WiFi turned on and after a few minutes from entering sleep mode, the WiFi got disconnected, both WiFi and data. I have installed the last update again and again, rooted, unrooted, tried every option from WiFi and i still had the same problem.
So i timed the time when the WiFi disconnects and it was exactly 6 minutes. So i thought that it must be an option that does this. So i unchecked the Quick Power Saving icon from Switches and ... SURPRISE! My WiFi stays on continuously. So, the problem is from the system power saving settings. I hope this helps all of you.
P.S. Love this forum! Thanks for all your help!
I believe I found the problem, some how it is not the phone but my wifi router (and all routers) is the problem. Go into your router settings and look for the "Beacon Interval" and set that number to 50. I'm not going to explain what the beacon interval is, go google it and you will see. I switched mine and now the wifi on my phone does not switch off when in deep sleep.

All wifi and data disconnects when screen is off but only below 50% battery?

Hey guys I have searched and searched for a remedy for my problem, first off here is what I am running on my i9250:
ROM: Beanstalk 1.190
Kernel: KUBO-AK r46
Baseband: I9250UGLL1
Now the problem is this, all data (wifi and cell data) randomly disconnects when my battery is anywhere lower than 50% and gets increasingly annoying the lower it gets. I do not have any powersaving features enabled and yes I have changed the advanced settings in Wifi (Keep wifi on during sleep: checked to Always, Avoid poor connections: Unchecked, wifi freq band: 2.4ghz only, wifi optimization: unchecked; i guess that is a powersaving feature as well)
Still the problem persists. The other problem is, it happens to my cell data as well, when I wake the phone up (when it is under 50% or so) I see that only then the cell data starts to reconnect, and then I get all my whatsapp messages and emails all at once. (same goes with the wifi) Keep in mind though, when I have the phone plugged in and charging the wfi or cell data are active when the screen is switched off. The problem only occurs when the battery is below 50%.
Is there anything I can do about this, it gets really annoying because I have to wake the phone up and keep the screen on, in order to get messages. I know there is a widget that keeps the wifi active regardless of the battery level, but what about the phone data when I am out and about. I need to stay connected especially with emails and whatsapp because that is how clients stay in contact with me and it sucks when they send messages and I get nothing and they have to wait for me to check or wake up my phone for the data connection to re-establish whether it be on wifi or data.
Anyone knows how to fix this problem?
No one?
Have you tried changing your kernel? Sometime kernels can have weird affects on your device.
İ think this is one of kernel problems. Battery section is controlling by kernel. Find a kernel and use smartassv2 with sio.
Yes, I swapped around a few kernels and same effect. I really am at a loss.

it happens to me as well, not sure about the 50%, but when I am at home with 3G and wifi on very often if i turn on the phone the signal bars are grey and not blue and it seems that connectionwas lost during sleep and is being turned on again
btw, I am on stock 4.2.2
Try to format /system. And reflash. İf its not work, flash stock rom and flash custom rom. İm not sure if it will work.
Believe me, I have tried every wipe and every rom/kernel combo that is humanly possible
Then problem is hardware thats what I thought. Unfortunately. Technical support helps.

Does wifi drain battery when moving about?

At home using wifi. When at work or on the road, LG G4 uses LTE but wifi setting remains on. Question, does this reduce battery life? In other words, does the phone keep looking for wifi networks and drain the battery in the process? If so, should I find an app that turns wifi off automatically whenever leaving home?

I would asume yes it uses power always trying to find a open hotspot even if data is on. If u leave wifi on its on all the time. Prob in a lower power state just searching for open spot or known wifi . instead of downloading or streaming which bring it to full power.
I am going to try an app called wi-fi matic for the next few weeks. It allows turning off wifi radio when away from home. Let's see if it makes any difference with battery life.
