Hi,
I'm wondering some things to optimize my battery life, but couldn't find any answers so far:
1) When Wifi and APN both are ON, Wifi will get priority. But the APN-setting is actually still on. Will it drain the battery, or should I always turn APN off when Wifi has been connected?
2) I have set Ultimate Juice (or Juice Defender) to turn on APN every 10 minutes during 1 minute to check for updates. But when I turn off APN, Juice Defender can't turn APN on himself to check for updates. That means that I have to remain APN ON. Doesn't that drain the battery, or is Juice Defender turning APN off on his own way?
3) I noticed that when the screen is off in standby, Android will turn off Wifi and APN. People are saying you should turn off APN and Wifi when not in use, but since Android turns both off while screen is off/standby mode, what's the use of turning both off manually? I think you could even turn them on all the time since they will get turned off when the screen goes black.
4) e.g. You're in a situation without any internet access. Apps like the Friends Stream, or Mail want to check for updates every 5 minutes. the consequence is they can't update because there's no internet connection. Does that action always drain the battery some more?
wtf no one??
under the wi fi advanced settings.. you can set wifi to never sleep... this should mean that your not using the apn connection...
I think apps try to update and if they do not succeed, it will be cancelled. I doubt the apps will continously check for updates until they get a fix. Same with Weatherbug. I sometimes see Weatherbug last updated hours ago, even when I have had internet access for the past hour (I have set it to update every hour). That was when I had unchecked 'enable always on mobile data'.
There are options available for wifi under advanced menu to set it to always stay on, or shutdown after 15 mins of sleep.
There is also an option available to always have data connection on. This will keep data connection alive even if phone is set to sleep.
Do you mean "mobile data connection" everytime you call it "APN"?
There's WiFi and that; two ways to access the net which pull power. WiFi can be disabled quickly and easily through the widget. So can the mobile data network: http://yfrog.com/0ymobilewidgetp
Leaving it to 2G when you don't need 3G or when 3G reception is bad saves much power. I'll need to do more experimentation before I can answer your other qs with assurance.

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
Hi all,
I just purchased Tasker and was trying to do a simple task that
automatically turn on/off the wifi when I'm at home. All I do is:
Contexts | Tasks
Cell Near | Turn On Wifi
Wifi Near | Turn Off Wifi (Exit task) (optional?)
I also have another profile that simply turn off the wifi when I lock
the screen.
The problem is that whenever I unlock my phone, the wifi is connected
correctly to my home wifi, but after likes 10-30s, the wifi turn
off itself so my phone back to use 3G network, and after 1-2min it
reconnect itself to my home wifi again, this seems to happen again
and again? So what is the problem here? Hope someone experienced with Tasker can help me.
Thanks
you can go to wireless setting -> advanced setting to manually disable wi-fi hibernation upon screen off, or you will be creating an "infinite loop" with your task being triggered repeatedly.
after all, I found this too much a perfect partner to my android, and it actually helps me getting rid a number of applications that likely consume RAM individually.
Done that too but no help. Sometimes when I unlock the screen and although all the requirements are met (Cell Near, Wifi Near), the wifi still not turned on, I go to the wifi setting to check and see that it keep displaying "obtaining ip address from ..." and sometimes it just says "error". Don't know if this is because I use JPE modem with JPY base? Maybe I will try flashing a correct ROM and see if this problem can be fixed.
Cell Near | Turn On Wifi
Wifi Near | Turn Off Wifi (Exit task) (optional?)

It appears to me that this what you have configured.
Cell Near (Cell tower near your home) - Turn on Wifi - Which works
Within range of certain WiFi Ap (Your home WiFi?) - Turn off WiFi - Which could be causing the WiFi to switch off in an endless loop?
Maybe you want to check your config logic?

I thought the Cell Near & Wifi Near go together as they're in the same profile. The logic should be if Cell Near & Wifi Near then Turn on Wifi else Turn off Wifi. The else part is the exit task of this profile. Even if I remove this exit task, the phone still turn wifi off by itself?

Remove the wifi near. If Cell near is true, then it means that you should be within range of your wifi and therefore the wifi near statement is redundant. If you are within range, wifi will automatically scan and connect to your wifi.
The exit task should only be to turnoff wifi. It is implied that exit task kicks in once you are out of range of your 'Home' Cell Tower.

I don't think wifi near is redundant. Being within cells that cover my house doesn't mean that I'm actually in my house right? So I think the two layer Cell Near and Wifi Near is efficiently enough but why it can connect to wifi in the first place and seconds later the wifi is turned off and on and off and on... I don't know why?

I just guess when you leave your home, you are no longer in proximity of your own wi-fi access point so you just get your wi-fi off.
Though, as you leave further away from your home, your mobile begins to search for cell towers that are not supposed to be covered in your "cell near" context, and once your mobile get connected back to your home cell, your "wi-fi on" event would be triggered once again, and the process repeats.
I think the best way to solve this, apart from including more cell IDs, is to set the cooldown period of your first profile (in profile setting dialogue) to a certain value, saying 10 minutes (or a sufficient duration for your mobile to completely get away from your home towers)

I was staying at my home the whole time I was using this profile
Check the value following the / symbol
Are you using the scan function in Cell Near? It should retrieve the ID of the closest cell tower with a value following a slash:
CDMA: 99999 / 8
Try changing the value to a wild card:
CDMA: 99999 / *
I have been using the following to turn WIFI on and off:
Add a new Profile and select State. Then select Cell Near and click the Scan button to find which Cell Towers are near your current location. Check the Invert button. Add a Task to for WIFI and set to Off.
Duplicate this profile and uncheck Invert and set WIFI to On.
Confirm Cell Tower IDs
You can confirm the Cell Tower ID by downloading one of these free Apps:
Antennas
Cell Tower Locator
You will want to use the BSID number listed in one of these Apps in Tasker for Cell Near.
I've noticed that since the 2.3.6 update, my phone no longer will reconnect to the 4G data network when the screen is off, and wifi calling is active. In order to keep wifi calling active, I set my phone's wifi sleep policy to "Never". Here is the exact scenario:
1) At home or work, my phone activates wifi calling when it connects to the local wifi network. This causes it to disconnect from the cellular voice and data networks.
2) At some point, I leave the wifi area while my phone is in my pocket and the screen is off.
3) The next time I turn the screen on, I see that the 4G icon is gone, but immediately appears as the phone connects.
While this may be a minor inconvenience, it means that all services that rely on the data network (Gmail, Skype, etc) will fail until the screen has been turned on once. Has anyone else observed this?
All of a sudden my wife's 5x won't see networks keeps saying disconnected. Started just before the prepare for nought update. When we choose setup/wifi/advanced network notification, keep wifi on during sleep, use open wifi are missing.
We've tried some old thread fixes, turn on blue toothe, toggle wifi and airplane mode, reboot.. nothing.
Please help. .
