battery usage WIFI vs 3G - Fascinate Q&A, Help & Troubleshooting

I tried testing which of the network connections spends more battery between battery until it drops to 80% from a full charge, with never turn off option.
Apparently my phone maintained a lot more with 3G instead of Wifi.
I have Super clean 2.9.2, EC10 3/26 kernel(now updated to 3/27), and DI09 modem.
Ideally which is likely to save battery more than the other?

What if the phone is next or always on the router range? Would that change the result?

A lot of people stated that using wifi has better life, and I'm one of 'em

WIFI uses less battery because the data travels in a shorter distance, and signal is stronger than 3G.

Best radio for CM7?

hey guys, I'm running CM7 and I have tested several different radios and they were all pretty bad. Does anyone have any recommendations on what I should use? Thanks!
Define "bad."
Speed test are not always accurate, if that's what you're getting at.
Used mr2 and was good. Every upgrade seems to be better. And the newest 802 is ridiculously fast with nice switchovers between Gs and no issues.
I used 2.5 when I was running AO5PTH3ORY... it worked great. I had no issues connecting to 3g and 4g.
+1 802 working great for me. I've been running DroidTh3ory's AO5P roms, based on cm7.

Sorry, by bad i meant terrible battery life. Maybe its my area. No matter what radio I have ever used my 4g and 3g would always switch back and forth and I think that drains battery pretty quick..

Try recalibrating your battery if you have not. I would also stay off LTE as much as possible unless you need it. LTE just drains your battery like a thirsty man does a glass of water.

Massive battery drain, caused by switching internet?

Hello everybody,
I am confronted with a nasty problem.
My 2 weeks old s2 suffers under massive battery drain if using the 3g/hsdpa internet. I will explain it with a timeline:
In the morning, phone was fully charged over the night.
I start my day with 100 % in the edge network. I live on countryside, there is not just more :-/
I can listen to music, surf in fb, .... battery does not drop significantly. I think everything is fine.
When I drive over to the next city, where I go to school, 3g/hsdpa is available.
Phone switches permantly between 3g and hsdpa, even if signal is above 3 lines.
Internet is really slow or even just does not work!
Battery starts to drop massively!
As I write this, it's 3:45 pm, my battery is just about 25%.
Today, I only listened to music, played some mini games and bugvillage, tried to surf and checked ebay...
Technical Informations:
Cognition 1.51
Changed modem to kdj, read that it is better than kh3
Ninpo 2.1.3 kernel
Display is on auto setting
TW 4.5 Launcher
Apps running in background(just to receive/send informations,not opened):
Facebook
Whatsapp
Googletalk
Gmail
Bugvillage
Is there a fix for the switching signal, which causes this massive battery drain or do you know where the problem is?
Regards,
crapman

With email and other apps synching all the time, 8 hours battery life is probably quite normal. I can get thru the day till 9pm by emails every hour, no chat but I read a lot. Screen on time typically 3 hours..wifi and 3g on.
I use stock dxkh2 and speedmod t39

Sounds like a modem/radio problem you could try changing and see if it makes a difference.
If your getting weak signal it does drain the battery.
Could also be a rouge app causing wakelock.
Search for betterbatterystats app on the forum this should help you track down if an app is causing problems
EDIT: also if your only getting E at home try changing to 2G only
settings - wireless and network - mobile data.
This is a bug in the modem. Either play around with different modem versions and see if the behavior changes, or use the *#301279#* dial code to enter a hidden menu, and chose to release R99, this will disable H speeds and it will limit you to 3G, and not switch anymore. It may improve battery life.

Why does Samsung build a phone which battery lasts 8 hours using all functions???

Yeah, I think the same, do you know which modem/radio is the best?
I installed this app but it makes me not more intelligent than before.

For a bug, which is caused by Samsung, i have to decrease my internet speed?
I want to have fast internet....?!
Nevertheless, thanks for your replies!
modems are kinda region specific, so what works best may not be very good for you. I've stuck with KG6 but i hear that the KH3 one is pretty good
In betterbatterystats click where it says process and change it to wakelocks, these are the apps keeping your phone from deep sleep when the screen is off. so the ones with alot of time below them are not doing your battery any favours.
If you switch to 2g in bad reception areas it can really help, i know its hassle to keep changing but if your handset is constantly switching from 2G/3G your not getting fast internet anyways
hope this helps!

It's switching between 3G and H/H+ all the time. I have the same problem sometimes, it has nothing to with signal strength it seems.
Try flashing different kernels, may help. Check and control what is constantly synching..
No phone with big screen lasts 24 hours with all sync and push and chat/streaming/browsing, even blackberry.
the battery does take some time to cycle and will give better battery life.

The dial code really helped me, battery is much better and I can now use my internet properly, despite I am a bit sad not having HSDPA speed :-/

battery increase?

Is there a way to disable 4G, so the phone uses 3G instead and uses less battery or even better 2G? It seems as if the option is not on the Amaze as it was on the G2.
I have speed rom 4.0 I think. Gonna put 6.5 on soon.
Also is there a way to make your battery last longer if you game alot or watch movies?
You can try buying an Anker Battery for your Amaze, I got one off eBay and it's a noticeable difference (nothing huge though)
You can try using an app called Widgetsoid to toggle your 4G/3G but I'm not 100% sure it'll work with every ROM out there so give it a try

4G is 3G. 4G is just a marketing term. It's just a faster 3G network.
You can switch to 2G in the Mobile Network Menu.
Turn off your data, lower brightness, turn off Bluetooth, GPS. There are a lot of things you can do to save battery.
Hi, I moved this thread to Q&A. Please all question threads in that section. Also, please search the forums before posting your question. Most times, your question has already been asked, with answers.

turn down the screen brightness, undervolt, use a better Kernel / use a powersaving governor (throttle down the frequency quickly when not needed)

I already bought the Anker battery 3 months back more or less. One day my phone just shuts off, and now it doesn't charge anymore.

Well "faster 3g" might be picking up more battery than "regular 3g". I have Simple Mobile, so their "SIMPLE 3g speed" is not exactly the fastest. Seems like "fast EDGE" speed to me.
My brightness always goes up by itself even when I turn it down for some odd reason. I have my data and wifi off when I don't use it. I rarely use GPS and bluetooth, so most of the time they are off. I don't use that JuiceDefender crap cuz it doesn't do much. Doesn't it slow down your phone?
I can't find the 2G in Mobile Network Menu (which is why I said I’ve seen it in G2 or it might’ve been MyTouch 3G Slide. I'm using SPEEDROM 4.0.)

I don’t know the good settings to undervolt. I’m scared about screwing up my CPU. You can choose kernels to use?! I didn’t know that (I thought a ROM had a specific kernel requirement), but wouldn’t WiFi be broken or something.

all of them should have no problems with wifi or anything (well, some have "beta" versions that might not have wifi working). each of them implements different things to help give you performance or battery or undervolting etc... try each of them and see...
If you can't find it in the settings you can do the following...
Open your Dialer ( yes, like you're going to call someone)
Dial *#*#4636#*#* then pick Phone Info. Scroll Down and find Something that says "GSM Auto (PRL)" click on it. Now you can change that to "GSM only" and you will have just 2G speeds. It will save battery life if that what youre after.

There is an app on the Play Store that goes directly to the 2G/3G menus to toggle it. Unfortunately there is no way to directly change it outside of the settings menu.

Or better than that, go here and download the apk http://forum.xda-developers.com/showthread.php?t=739530
It will set it to 2g while screen off, and turn 3g on after screen on or unlock.. so if you have weaker signal it will absolutely increase battery life, but 2g uses less battery anyways.. there is about 2-3 seconds after screen on before it switches back to 3g(4g, whatever). I've been using it for days, I am happy.

Better for Battery Life: Wifi or HSDPA

Hi all, Blue here,
I am using a slightly modified rom made bsaed on the hktw rom made by a local. I am just wondering if wifi or data takes more battery generally?

2g<wifi<3g<4g for battery drain, or at least that's what i've found from my side, with 2 g taking up the least battery, and 3g/4g taking up the most.

On the Droid Razr (and infact any Android device) wifi uses MUCH less power and resources than HSDPA/3G+ services. The reason being that the gain needed on the radios part to receive a packet via wifi is (generally) much less than over a cellular connection, due to the quality of the signal being much higher. It hasn't got to work as hard to get a good set of packets to work with. Your phone will be working like a mad thing trying to buffer a YouTube video on HSDPA - dealing with massive packet loss and syphoning the 'good' data from the 'bad' data - whereas on wifi with much less packet loss and a higher rate of that 'good' data being received, it can relax a little.
My advice on battery life - download a data "toggle" widget and place it on an unused home screen. Whenever you are not using any mobile data services turn it off using this widget. Leave wifi on only when at home/a location where you know you will be able to use it. Turn it off when you go out. When you want to use mobile data when wifi is not available, just toggle it on. I get 3+ days of always-on use using this method.

Thanks guys, coz I notice that it seems like when I am using wifi, the batter goes faster. Maybe it's because when I am connected to wifi I use it more often? Thanks again

It could well be. Or if you have applications that are configured to only sync/update when on wifi, this will naturally put your phone to more use than if say you only used 3G/HSDPA for checking email.

When you say you have compared them with 3G , it means the phone's data sync causing this problem is out of question. As in both cases ( wifi and 3G) the phone would connect to data based on the set intervals.
Possible cause: if you have multiple wifi sources near your devices and you have granted them access, here your phone constantly tries to connect to the best available wifi . If this is true , just use wifi managers available on Play store or remove access to unwanted wifi routers/access points.

[Q] Wifi settings for min. battery consumption

Hi,
I was trying to search but didn't find a conclusive answer.
Which option is better in terms of battery consumption, especially during the night:
1. Turn off wifi and use cellular data.
2. wifi + Keep Wi-Fi on during sleep set to "Never".
3. wifi + Keep Wi-Fi on during sleep set to "Only when connected".
4. wifi + Keep Wi-Fi on during sleep set to "Always".
Thanks in advance!

You have sort of answered your own question... for Minimal battery consumption set it to 2 (Never). I would recommend just sticking to 3 which is better for overall use or just toggling your Wifi yourself.

Thank you for your answer.
But isn't setting it to 2 during night is the same as turning wifi off and use cellular data instead?
So does it mean that cellular data is better in terms of battery?
And why 3 is better for overall use?
Lets assume that cellular data is free of charge for this matter, and my only concern is battery.

Listen to Coreym and set it to 2 all the time, wifi uses way less batterylife than 3G mate. 3G sucks the life out of your battery. Just try it and you will see
what about using only 2G instead of 3G? How it is compared to WiFi usage?

Sure and while you`re at it disable 3 cores permanently, lower brightness to 0 and don`t ever use your phone for better batterytime, 2G will consume more power as it is slower and so it takes longer to retreive data.

Just looked in my own settings and i have option 3 checked: wifi on Always. It also depends on the user, do you use wifi a lot or just once in a while. The best thing to do is try a few settings for yourself and see which setings consumes the least amount of battery.
Settings WiFi on always .
WiFi / mobile data not in use or not required = turned off via toggles .

But I do want data during the night - for example for whatsapp, emails and so on. So turning both off is not an option for me.
- On one hand, people here say to set wifi, but "never" during sleep. But that means to use only 3g during the night, doesn't it? Or I'm missing something here?
- On the other hand, 3G costs more than wifi in terms of battery.
So I don't understand how these two go together.
I have set to "Always" so the device have not to reconnect when unlocking screen, what drains battery imho.
But in the night I set flight mode on cause I want and need to sleep and don't need new SMS or Whatsapp or calls

Can someone clarify this for me please?
3g doesn't cost more in terms of battery so long as you have a very good signal. If you don't or if for some reason the network has a problem then it will drain the battery.
What I recently started using is a program called ds battery saver which toggles wifi or 3g periodically depending on what you set it up for so that you do get night time data but not on all the time. That helps with battery
