Hi,
I know battery drains faster if I have bad connection in my area. When I go in my battery option, I know the 'yellow' connection (see attached image) means i have bad connection and my battery drains faster because of that. My question is if I turn wifi calling on and turn off the data, which one will drain the battery faster? wifi calling or the 'yellow' bad connection?
Thanks.

Does anyone know where to set the wifi "not to sleep" during stand-by. I try to find the setting but cannot find it.
Currently, it seems like HD7 uses data connection (GPRS) to sync e-mail , calendar, etc. instead of wifi while phone is in stand-by mode. (I turn off data connection and my inboxes are not syncronized during stand-by even I turn on wifi)
It means i still have to pay for the data connection usage even i use wifi at home.
Wi-fi will stay on during standby if you plug your phone into the mains. This is to stop your phone running itself out of battery power, which it would do quite quickly if Wifi stayed running all the time.
So your answer is, plug the phone into the charger when at home.
Thank you very much
hey everyone, i'm wondering:
when i'm not home i have mobile data turned on. i stopped switching between 2g and 3g to save bat-life, because i felt it to be too much of a hassle...
i only turn on wifi if i want to download/update apps or mess with the dropbox.
but i want to keep my defy online to receive emails and stuff.
so, what drains the battery faster? wifi or mobile data?
i could imagine that the mobile data drains the battery less, because regarding reception and stuff, this "part" of the phone is turned on in any case...
anyway, does someone know an answer to my question?
thanks in advance.

I took this from android-hilfe.de:
GSM/EDGE Standby 11,6 mW
UMTS Standby 18,3 mW
WLAN Standby 7,8 mW
EGDE Download 853 mW
UMTS Download 1349 mW
WLAN Download 1158 mW
seems it depends on 3G time and most of all change 3G/2G
regards
thanks mate, looks like from now on ill be switching to wifi whenever there is a known network
I think thats the best solution. btw great german forum, works perfectly with the devs here
But from my observation, in standby mode, wifi (with network) consumes twice the battery of 2g (edge). In my case, wifi consumes 1% battery every hour, while 2g consumes 1% battery every 2 hours.

In these download wattages, it is worthwhile to consider that an EDGE or UMTS download of a given file will typically take far longer than the WLAN download. This means that the download will consume more joules from the battery.
I See my wifi has used 30% of my battery but ive been on 3G all day, does it drain the battery searching for networks?
It does use some power when searching for networks. There is probably an APP or settings that you can change to set the Freq of checks maybe. Or you can just turn of the Wifi radio when you know your not going to use it.

Yes it uses a lot of power if its regularly searching for networks. Especially if you're moving around and seeing dozens of WiFi spots. Just turn off WiFi when not in use, simple as that.
A lot of custom ROMs have less aggressive Wifi seeking intervals. You can usually set it manually with ease too. Lots of apps out there if you don't want to do it manually.
All that was said is true, but still I find that 30% usage for Wifi just for searching nearby networks is a little too much...
Although I haven't got anything to compare with, I always turn wifi off if I'm not using it during long periods.
Regards
I turn wifi off when it is not needed and battery life goes from one to two days.

I've been using Tasker to turn wifi on at home/work and off when I'm elsewhere. It's using cell towers to determine location, so hopefully it won't impact the battery much.
I leave wifi on 24/7, today it has used 2% of the 60% battery i've used.
I travel through london so I assume it is constantly finding new wifi signals.

Y5 Battery Saver .. on the market, free. Turns on/off Wifi based on known networks and cells in the area of the AP.

I leave wifi on all the time as well, and I also only have used 2% of the 70-80% battery I used up already.
Try going into wifi settings, then advanced wifi settings, then turn off the new wifi network available notification option.
This increased my battery life slightly.

Y5 - Battery Saver helps out tremendously! I barely ever use more than 2% when home all day...although that may be a bug but I started a thread for that already.

That 30% displayed can be deceptive since it's based on the amount of battery discharged and not entire battery capacity.
Well wifi, when on is looking to connect to known networks. If the signal is weak it will disconnect and connect to another network near by if there is that has better signal. This process does use some battery. The biggest drain will occur when you are actively using wifi, that is when you download or upload. So the best way to save battery, is to close wifi when not needed. If however you want wifi you can set it to never sleep. This way even if the screen goes off wifi will be connected and your device wont use the 3G which is way more power hungry.
I have N7 LTE 4G and most of the time I use it with Wi-Fi only. Yesterday I decided to get a pre-paid Sim to use for Data only when I am in a place that doesn't have Wi-Fi with 1GB per month data for $2.90 (yes it is THAT cheap in Egypt ) but only 3G/HSDPA/HSPA+
Now the problem is, Cellular network is always running and battery drains fast even though I use the internet on Wi-Fi and turned Mobile Data off.
I've read that I can turn on 2G to save battery and disable the cellular signal and indeed when I check 2G, I get no bars in cellular top icon and it says No Service (Network Name) BUT..... as soon as I open internet browser or any internet app, the cellular network works again by itself although 2G is still checked !!
Is this some kind of bug ?
The only solution I can do is to turn on Airplane Mode and turn Wi-Fi on afterwards which is not ideal
Any help would be much appreciated.
There is an app called Battery Monitor Widget that has "Tests" tab when I press on it, it opens "Testing" page in which the first option is Tablet Info. There is a list called "GSM Only" in which there is a toggle to Turn Off Radio and indeed it turns it off
I use airplane mode then just turn wifi back on to keep the cellular radio off.

How much battery does this save ?

It really depends on your signal strength. If you have strong signal you shouldn't see a huge difference. If you have a weak signal then it could be a big boost to your battery life.
And I'm not sure why you said that it was "not ideal" in your initial post. That's really the best way to go about it.

Signal is always good but I don't even need it to be there when I am on Wi-Fi as the tablet has no GSM phone functionality.
I think there is something wrong elsewhere with the battery draining so fast other than the GSM Radio being On.
The battery was good and lasted 2 full days with moderate usage and Wi-Fi always On but it started draining fast when I left the tablet untill it totally discharged and woke up to find it powered off and then charged it till 100% and battery reached 55% in 10 hours with very light usage
It sounds like you have an app draining your battery in the background. Try installing Better Battery Stats and see what's using all your power.

Yes, the developer also posts it here on XDA.

Hello,
I'm having some problems with my ZE550ML. If i set the bands to 2G/3G/4G and leave both cellular data and Wi-Fi enabled, my cell signal just drops from minute to minute. If i disable the wi-fi 4g works fine, also 2g/3g and wi-fi works. It seems like wi-fi and 4g won't work together.
Also Cell Standby drains a lot of battery and according to the stats every time the screen is turned off i have no signal, leading to 50% no signal active time. This must be a bug because i have full signal when the screen is on, and i receive calls and messages when its sleeping.
Does anyone else have these problems? Any suggestions?
