I have set the Wifi to disconnect when the screen is off. However, it does not seem to disconnect. Anyone has the same experience? I want the Wifi to disconnect when the screen is off because Wifi is using up about 3% of the battery per hr.
An app such as juicedefender may help you out...i've seen similar drain via wifi.
Thanks. Let me see if it's Honeycomb compatible.
Hi,
I thought that I could use Tasker (https://play.google.com/store/apps/...EsIm5ldC5kaW5nbGlzY2guYW5kcm9pZC50YXNrZXJtIl0.) to save battery life. So, what I did was to prepare the following profiles:
a) Disable autosync, enable it to 3 minutes every 30 minutes. Sync only between 6:30 and 23:05.
b) Enable autosync while on AC power, disable when not.
c) Disable wifi, enable it for 15 seconds every 15 minutes so the system would have time to connect to a known wifi if available. Then disable wifi unless its already connected.
d) When a wifi connection starts, do nothing. When it gets disconnected (like when I leave home), disable wifi.
I only use EDGE. I only sync gmail, contacts and calendar.
Before this, I had autosync and wifi on all the time so I believed this setting should conserve battery. Everything works, Tasker app itself is not draining much from the battery (according to Betterbatterystats its really negligible) but still, I have a considerably higher energy loss than with default setting.
Do you know whats the reason for this? Is is caused by the wifi enabling and disabling - taking more power? Is it caused by the fact all sync gets done at the same time? Or why is that?
Im generally happy with the Nexus S battery life but this outcome makes me curious ...
EDIT: My advanced wifi system setting always was "never disable wifi when screen is off". Also, for the purpose of this test, I disabled wifi AP on my router to check just for the outcome of the wifi search.
Check out your Awake time (can find this in BetterBatteryStats), you'll probably notice the phone stays awake for longer than it would normally. Normally the phone would go into a practically permanent "sleep" state, powering nothing but your radio, when the screen is off and doing nothing. It would just wake up every X minutes to autosync or for other alarms (exchange sync, etc) and then go back to sleep. I wouldn't be surprised if it is solely the wifi option.
Depending on the advanced setting in the wifi options, it keeps the connection indefinitely or drops it after a certain amount of time, i think around 15mins - 30 mins. This may need to be changed to fit the circumstances.
Overall though, benefiting from the use of Tasker or similar program for battery life purposes doesn't gain much over what android already does (albeit still with alot of room for improvement).
Well, I should've mentioned this: My advanced wifi system setting always was "never disable wifi when screen is off". So thats not possible reason.
Also, for the purpose of this test, I disabled wifi AP on my router to check just for the outcome of the wifi search.
I basically believed that before, the phone had wifi on and checked around every now and then. And with the new setting, it would check less often, therefore saving battery.
Awake time is about 40 minutes in 7 hours sleep.
EDIT: Maybe it would help to adjust the times better.
So, after no problems for 3 months, my stock AT&T S4 has suddenly started with some odd behavior where wifi is unresponsive for 30 to 60 seconds immediately after every time I wake it up. Then wifi works normally.
The wifi connection icon stays on during this, and I see it trying to upload and download.
When the phone is asleep, it syncs appropriately over Wifi and I get all of my notifications.
This happens on all wifi connections. 3G/4G is unaffected.
I have wifi sleep disabled in the wifi Advanced menu.
Any guesses as to what might be causing this?
Hi guys
I noticed countless times that randomly when turning on wifi and then turning it off, the "always allow scanning" under advanced options is ticked.
I noticed this because then under battery usage you will see wifi active even tho main switch is off and 99% of the time that is why.
Is it a lollipop 5.0 bug or is it some of my apps that can switch that option when they detect wifi has been activated?
Also, it seems that if i dont turn on wifi in the first place, that option never becomes active. Battery life is very good on my phone so not a deal breaker....
Anyone knows?
Thanks
So I was using PA and now on PN. FK then and now EX kernel.
I still have the same problem. The Wifi is ALWAYS ON even after I turned it off or after I placed it on airplane mode.
Now before you all say turn off Wifi Scanning, Bluetooth scanning and keeping WiFi on or off.
Like in Pictures:
-Bluetooth and Wifi Scanning is off
-Keep Wifi ON during sleep only when plugged in
The only way I can turn it off is to restart my phone or reconnect to a network and disconnect.
I notice if I exit the house and turn off Wifi some time later the WiFi will be off but seen in detail battery stats and stays that way till I connect to another network and disconnect properly, Or I leave & turn off the Wifi properly before I exit the Wifi range.
WHAT IS THIS PROBLEM?
It''s kinda that I need to always do this. If I forget and I have a large bar of WiFi and need a restart. -_-
I have average battery life 4hours SOT and get 12hours of Battery life. Clean flashed PN but flashed a back up of my Apps from Titanium.
Thanks guys in advance!!
Hope someone can give me a solution for this!
Have a nice one!:good:
