I've been seeing mixed reports on battery life with keeping your wifi always on. Some say keeping it always on extended their battery life.
What do you have it set as? And how has it affected your battery life?

I keep always on but it does the opposite
I always have WIFI and bluetooth on. Take it off the charger in the morning and battery is usually 70+% at end of day.
GPS off. cellular data off (i use a prepaid voice-only service).
Wifi Sleep Policy is 'Always On', but I use an automation app (MacroDroid) to actually enable/disable wifi when I'm in/out of range of trusted SSIDs (using CellID triggers).
With autosync on and locations services set to battery saving with wifi scanning when disabled off I get the following results.
Wifi enabled connected to SSID (3G data is on but Android automatically prefers Wifi) - standby drain circa 1% per hour.
Wifi disabled (as no trusted SSID in range), 3G data on - standby drain 1 to 4% per hour (depending on network strength)
On 3G data with Wifi enabled but not connected to a SSID - standby battery drain 2 to 6% per hour.

Hello,
My mobile broadband usage keeps vanishing.
I now have noticed that when I am in range of my home wi-fi, and wake the screen up the GPRS is connected, it then rapidly switches back to wi-fi.
What is causing this please?
WiFi is disabled when the device is in Standby to save battery life.
AFAIK it can be set to be always on via Reg-tweak but it will drain battery very fast.
Mmmm yes I realise that, but what happens then is that the 3G data connection then connects and drains the credit.
NoData widget
I have just found the solution a little widget called NoData.
Toggles GPRS connections. Added it to my drop-down menu no problems, Wi-Fi can switch itself off and on as and when.

Hi, what is difference in battery consumption between
- wifi on & connected to network (no or low network activity on background)
- wifi on & disconnected (so it constantly searches for wifi networks)
- wifi off ( its exactly 0.0 mW ? )
(I want to configure wifi sleep policy / llama app to save battery)
And when I was charging, android shown 100% battery, after I removed cable it was only 97%. Or after phone startup it shows 10% more battery as I had before turning off phone.
Can I calibrate battery if I dont have root? (4.2.2 stock S4 mini)

yes you can calibrate battery without rooted access. :good:

Yeah just using your device by gaming or anything until it dont have power and turn off by 0% of your baterry..
Then plug your charger without turn on your device.
Wait until 100% unplug then turn on. Bateray stat will on 99% or lower.. then turn off your device then charg again until 100% and let it overcharge about 15-30 minuts.. unplug an turn on. Should your device calibrated now. If itsnt yet. Just reapeat the first step until 3times. If nothing change. Just root and calibrated with simple way

Im having this recurrent issue where the wifi apparently is never off, I look in my battery stats and it just has one solid bar even tho I have been off of it for over a hour out of the 3 hrs ive had my device disconnected from the charger. Anyone else having this issue?
Do you mean "off it" as in away from your wifi or disconnected, or "off" as in disabled wifi connectivity?
The battery indicator shows "wifi on" as long as the wifi module is enabled. It will keep searching and trying to connect to known wifi networks even if you manually disconnected from a network or moved out of it's range.
There are apps such as "Juice defender" that will try to determine where you want to have Wifi and automatically turn it on/off based on your position and other factors.
Go into Settings/WiFi/Advanced and uncheck the "scanning always available" box. Juice Defender isn't required.

Hello friends,
Presenting my first App - AutoCon
AutoCon will turn off the connections when screen goes off and turn them back on when screen turns on - Saves battery by turning off connections when you don't need them, Saves data usages. You can still be connected to internet by activating networks periodically when screen remains off!
AutoCon helps user to control the connections like Data, WiFi, Bluetooth with the activities of screen. This will prevent the unwanted usages of the network connections which leads to improve battery life!
Basic Principle :
It has been observed that the internet connections (WiFi and Data) are one of the primary reasons of battery drain. Also they consume battery when user don't need them. Typically users keep the mobile always connected to internet but majority of users don't require the always-on connection, but its sufficient for them to connect to internet when required.
Its painful for user to turn on the connection when needed and turn it off when done. Here comes AutoCon.
AutoCon will turn off the connections when screen goes off and turn them back on when screen turns on!
Also for countries like India where mobile data plans are still expensive, AutoCon will prevent the exes usages of mobile data by disabling it when its not required.
Main Features :
- Control Data, WiFi and Bluetooth connections
- Turn Off the connections when screen goes off
- Turn On connections when screen turns on
- Supports configuration of intervals after which connections are to be turned on/off when screen goes on/off
- Periodically activate connections in background (say every 1 hour, configurable) when screen is off so that user will not be totally disconnected
- Disable WiFi when its not connected to any network
- Disable mobile data when WiFi is connected
- Time Range: Connections will stay off in given time range (say at night 11 pm to 6 am, I don't want AutoCon to enable connections when I unlock the screen)
- When a particular app is running, do not disconnect when screen is off (for example I am speaking on Viber, so I want data to remain connected always even though screen is off)
- Everything is configurable - every interval, every setting.

I have a few apps that I need to be connected to the internet/data overnight and was wondering which would consume less battery power when the phone is idle. These apps are excluded from all restrictions and battery optimizations in Oxygen OS.
Currently I have it setup that wifi goes off when the screen is off and the apps I keep running overnight are connected to 4g/lte. This drains about 10~12% battery overnight.
Would it be better to keep these apps connected to wifi instead of 4g/lte? Do you think that would consume less power? I always thought keeping wifi on/connected to my home router all the time drains the battery faster than 4g/lte.
Any thoughts?
Wi-Fi is supposed to consume less power than data; makes sense since the phone doesn't need to use its antennas for 4G..
WiFi consumes less battery.
You should turn off that setting so WiFi stays on while the screen is off and you'll save battery.
Another vote for WiFi consuming less battery. Think about it: the WiFi signal just has to travel 50 feet or so to your WiFi router, versus cell data signal, which has to travel maybe a mile or more (depending on the location of the nearest cell tower - but you get the point). Or meters versus kilometers, if you deal in metric.
Pushing a signal a longer distance equals more power consumed.
WiFi vs. lte
With respect, I'm not sure and would like enlightenment.
If I turn off my wifi and set my phone to lte, then I'm turning off the power that goes to the wifi/antenna sub-system.
If I turn on wifi, my phone powers that, but still powers the lte connectivity to my cell carrier for phone calls and SMS messaging. Also, wifi -- while superfast -- constantly scans (and uses power) to look for a better wifi connection.
I haven't tested it for power consumption, but I usually turn off wifi when I go to sleep and I also turn off "mobile data." I don't need my Google and other data synchronized until I wake. I would turn the entire phone off to let it charge at a minimum temperature, but I like to keep it on overnight in case a close friend, relative or clients gets arrested.
