[Q] battery drain on SD build - wireless 2G/3G - General Questions and Answers

Hi,
on ACA forum I see people talking about 6mA drain, I only see such small values when I disable 3G wireless, is this what others are doing? on my area I have good coverage of 3G so if I enable it i always connect with 3G, with 60mA drain.
I'm too junior here to open thread directly on ACA forum...
TNX!

XDA Orbit 2 Auto Screen off Disables Wi-Fi

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.

data conection/wifi question

if i have bouth data and wifi turned on and i am connected to a wifi spot...do i need to turn off the data conection first before it will stop sucking my topup?
shouldnt the device make sure it uses wifi if wireless network is available?
No, you don't need to.
When you connect to a wi-fi connection, the 3G data will automatically switch off (logo on status bar will go away) and it will return when you switch wi-fi off.

what?
The phone will prioritize the WiFi connection over the 3G connection unless the WiFi is turned off, it's signal drops out(resulting in a disconnects), or you have the default still set for WiFi to turn off when the screen is off.
Am I right in thinking that although the 3g connection will kick in when the wifi signal is lost the phone will still continue looking for a wifi signal and therefore impact on the battery?

Once the WiFi signal it's connected to is lost, it will switch the data 3G connection back on. Once you're out of range of remembered WiFi networks, it does scan for new/known WiFi signals to automatically connect to(only in the case of known signals, it will not try to connect to unknown networks).
As far as impact on battery, I don't think it's much. Only one time has WiFi ever creeped up on my battery use meter and that was on a particularly light day. I still finished my work day at little over 70% battery. There's an app on the market called WiFi Toggle which can help you automatically manage the phones WiFi chip. For instance, one setting will let it turn the WiFi on for a second, scan for known networks and connect if it finds them. If it doesn't, it turns it back off.
That's as I thought, thanks for the confirmation. I'd really like something to make the android phones act like the nokias in this respect - only turn on a data connection when needed (ie when the browser is fired up) and also prioritise the connections such that if a pre programmed known wifi network is available it will connect to that but if not switch to 3g data. There is no scanning for wifi networks all the time.
Nice to know it doesn't seem to impact on the battery though and yes before anyone mentions it I am aware android devices are designed to be always connected

I've been saying this for a while too. I came from Nokia symbian phones where they initiated the data session only when needed, like opening the browser etc. Android does not do this, instead it keeps a data session on all the time. Anytime you see that 3g symbol on an android phone means its data session is open. This is why android gets such poor battery life across all models and manufacturers.
Take one day as a test and simulate your symbian use by turning off mobile data, and your battery life will sky rocket on your nexus. So really It's just a trade off to make knowing you're always connected vs on others like symbian you need to manually do something to open the connection.
Oh and WiFi gets so much better battery life over 3g on android.

[Q] Wifi activation software based on location

Hello,
I would like to know if a software exists on WP7 that activate the Wifi which is based on own location...
On Blackberry plateform, this software exists => SmartWifi !
http://www.s4bb.com/software/smartwifi/
SmartWiFi leverages from the smartphone always being connected to the network carrier. By combining cell tower and WiFi hotspot information WiFi is turned off when not needed and turned back on when needed. Because WiFi is one of the biggest consumers of battery power when searching for WiFi networks this has a tremendous positive effect on your battery life.

WiFi losing Internet link after extended sleep

I'm having a weird problem with Internet link over WiFi where after phone awakes from sleeping local network still works but Internet does not.
I'm next to the router, signal strength is "Excellent" with 72Mbps link speed. WiFi icon under quick settings is orange. If I toggle WiFi it will work again for a while but then it will fail again.
I've never had this problem on GS2 or GS4 or even the laptop or voip which runs off wifi 100% of the time.
I read somewhere that setting static IP might help but that shouldn't be necessary. Is anyone experiencing this?

Question AutoWear for turning on LTE only when Galaxy Watch 4 is disconnected from Wifi/ Bluetooth

Hello everyone,
Is there a possibility to use AutoWear to turn on LTE only when the watch is no longer connected to the phone via bluetooth or wifi? I'm sure this will save battery life. One presumption is that calls over wifi to the watch would work. If they don't, not much point of turning off LTE.
I read a few posts stating that AutoWear for Wear OS 3 may not be properly optimized. Is this still the case?
I found a similar topic posted in r/AndroidWear 4 years ago and at that time, the developer had said that this isn't possible as they didn't have access to the LTE radio. Does anyone know if that's how things still are?
Thank you
No need for this. There is an "auto" option under mobile networks on the connection settings on the watch that does exactly what you say.
Oh that's brilliant!
Does it still stay connected to the network and turn off mobile data or does it pretty much go on airplane mode with only wifi and bluetooth being on?

It disables network connection shortly after you are connected to your phone via Bluetooth or Wifi.
Just to add that the same happens with Wifi. You can either fully deactivate it or have it on an auto setting where it turns on only if you are not connected to your phone via BT or for apps that required Wifi such as downloading songs on Spotify
That's exactly what I'm looking for! Thanks a lot for confirming this.
So essentially, if the watch is always connected to the phone, there shouldn't be much of a difference in the battery life between the LTE and non-LTE versions
There is only one problem - for me, setting LTE to car consumed 30% of the battery in 1 day, even though it did not lose the BT connection for a moment (maybe max 5 minutes).

Sorry, I didn't understand. Setting LTE to car? What does that mean?

I'm sure the author of the posts made the mistake. he wanted to say that the galaxy watch 4 has an error at the moment (01/21/2022)? at least for me, the bluetooth is connected, but the LTE connection stays connected as well, so the battery uses both BT and LTE, although my active2 when BT is connected, the LTE connection disconnects automatically ... although on the galaxy watch 4 the LTE connection is set to connect / disconnect automatically
