I don't get signal inside my work but we have WiFi in the building. No matter whether I have my mobile network on or off, my battery drains fast because it's searching for a cell signal. I normally turn airplane mode on to remedy that. Is there a way to keep the phone from constantly searching for signal even when I have mobile networks off so I can at least keep WiFi on?

what is better to use... when it comes to battery consumption...
wifi or 3g?
and is there a big difference in speed?
sorry for the newb-like question...
Wi-fi is better for battery life, and its usually faster than 3G
Sent from my SAMSUNG-SGH-I897 using XDA App
I found, according to Juiceplotter, that my phone dies a tad bit quicker when I'm connected to wifi at home as opposed to 3g. Funky but true. Slopes of wifi usage decrease a lot quicker than the slopes for 3g usage.

I was losing 30% every night with my phone sitting with the screen off and wifi set to never sleep. Last night I disabled the wifi and lost 3% over 8 hours even though I was only getting 1 bar or signal and have autosync on for weather, facebook, email. I am going to try to leave wifi on tonight with it set to only stay on when plugged in and see how much it will drop.

I agree setting wifi to never sleep will kill your battery quicker than 3G overnight. I use Wifi when I am at work because it is faster, I am not 100% sold on the idea that it uses less battery than normal data. Especially if you do not normally use a lot of data.
Hello,
Half of battery used on my cell phone is "Cell standby" and in Use details it lists "Time On: 1h 55m 3s, Time without signal:50%".
I'm excellent reception area (5 bars) and definetely did not have my cell off the network for half of the time. Does it include unavailable GPS location or some other type of "signal". This drains my battery very quick and I have not a slightest idea what does it specifically means. I have GPS, bluetooth ON but WiFi is always OFF.
This shows up on my phone when I leave it in the car in an underground parking garage. I haven't noticed whether it drains the battery more than when it has signal sitting idle, though.
It's time and battery your phone spends searching for signal and it's looking for cell signal not GPS.

So "time without signal" of 50% means that while phone was up half of the time it did not get cell reception? This is completely impossible in my situation.
I think it's a glitch. I notice it from time to time. You'll probably notice that when it happens it shows "time on" as twice the amount of time your phone was actually away from the plug.
Has anyone experienced high battery usage on 2.4ghz WiFi networks? I am seeing my battery drain alarmingly fast at work (2.4ghz) at university and on the train (also 2.4ghz) but at home (5ghz) I have no issues and get well over a day of battery with 5 hours on screen - at work if I turn WiFi off my battery completely levels out and gives good performance. If I leave it on I will get 10 hours off battery with 3 hours on screen and it'll die.
Anyone seeing anything similar? If your battery life is extremely poor try turning WiFi off or using a 5ghz band. Quite annoying. I am on UK Vodafone with the G920FXXU1AODG OTA. Although the battery drain on 2.4ghz networks occurred before this version.
I am going to turn my home router to 2.4ghz tonight and test it with that, could just be my work, uni and train have terrible wifi!!
This may be a noob question, but i'm wondering if using Wifi (while cell data turned on) uses more than cell data (with wifi off) alone.
Thanks,

Using wifi with cell data turned on will use less. I think having wifi actually turns the cell data OFF, but leaves the voice connection on. When using mobile data, I get a standby drain of about 2% an hour on LTE. On wifi, it's less than 1% an hour.
Yes, using wifi will use less battery. It only has to transmit data maybe 30 feet to the wifi router rather than maybe a mile or two to the cell tower.
When I got my S2 10 days ago, I followed advice to help with battery life by switching off wifi and NFC. Battery life has been very good (currently have 62% after midnight having taken it off charge at 7am). I charge every night so I could turn wifi on but what would the benefit be? If I go upstairs in my house without taking my phone the BT connection drops. Would wifi prevent this? Is it an either/or BT/wifi connection or can they both be used at the same time?
The point of wifi is to keep your connection when you loose bt connection. I question how much battery you save if you phone is constantly searching for bt connection. I have wifi and bt on all the time and have about 48% at 11 pm
