Does using wifi drain the battery? Is it better than using the actual 3G or 4G?
Sent from my HTC Vision using XDA App
I'm sure someone has a way more technical answer but I would think not. I have no issues with drainage on wifi, as on 2g its on the network constantly and not continually searching for towers.

If you are connected to a wifi network, it saved much more battery than using 3 or 4g. However, if you leave wifi on but don't connect to a network, it will drain battery

ok cool thanks alot man. Idk when I'm home I just like using wifi better, correct me if I'm wrong but it seems faster. Thanks again

Turning on anything more than necessary will kill your battery faster. Not always by a lot but everything does and wifi wouldn't always be faster because it depends on the wifi's local area connection. Best way to save battery is to go in settings/applications/manage applications the force close anything you don't need running. Make sure you know what it is you're closing or you could run into some problems. If you end up killing a system app and it won't reopen itself, its nothing a reboot won't fix.

DO NOT DO THIS.
Android has its own automatic task management system, and its best if you just let it do what it does best: manage on its own.

Well gee I do it all the time and it works fine. If it wasn't intended to be used I don't think it would come without root permissions and anyone who isn't an idiot will realize that force closing android system will cause problems. But if you wanna suggest a task manager that doesn't actually kill apps and adds some bloat ware, be my guest.

He's not going to recommend another task manager/killer, because Android already does it by itself. Plus, killing a task that is not finished just causes it to respawn. Task killers are unnecessary, and may actually hurt performance and battery life.

I agree that it's best to let Android clean it's own house normally, however I'm getting a little bit jarred off with certain apps starting themselves up at boot-time.
Paypal app for some reason has installed a service on my phone, despite the fact I've never even logged into it and I can't see why it would need a service running all the time.
Also since the latest Google Maps upgrade there seems to be something under my running tasks called Rate Places. I've not used the check-in service on GMaps at all, nor will I ever.
As well as this, since I've been running a modded CM ROM (SparksMod Extra Hot Sauce) then I constantly have Wi-Fi Calling running - again this is useless to me cos I'm not on TMob US.
Any suggestions for a decent app which can stop all these things running before they ever start, and keep them stopped?

Try "Autorun Manager"
I use it, but SOME apps will auto-restart. I think you need the Pay version of Autorun Manager to prevent those from re-launching.
I use the free version, and it gets rid of some of the problem.
WiFi is definitely causing massive battery drain on my G2 with CM6.1.1. I leave it on at night, and if I have 50% when I go to sleep, I'm down to 3% in the morning. Without doing anything.
I'm not quite sure why this is happening, but it is, and it sucks. I can't go back on 3G/4G right now because I'm at just about 4.8GB, and I don't want to go over my 5GB soft cap.
I wish I knew why WiFi was causing such battery drain...
Do you have anything updating automatically (Email, facebook, etc)? That would be my best guess. I leave wifi on when I'm at home and it isn't that bad at all. Also, I'm sure theres an app out there to let you see what is using the wifi for updates and such. I just don't know of one off the top of my head. I have an app like that for 3G data but it doesn't do wifi.
I just went through every one of my apps to make sure that nothing is set to sync, except Google Voice and Email. My battery is at 50% right now, so we'll see what it's at tomorrow morning.
As you can see from the screenshot, WiFi is using quite a bit of battery. I'm not sure why, but hopefully soon (after some testing) I'll have my answer.

Yup, 2 nights in a row, my battery has gone from 40% to dead, simply from sitting on my night stand. I wonder if this is why T-Mobile discontinued the G2... because they knew it would have battery issues, and they didn't want to deal with serving warranties? Hmmm...
Its a bit of a leap of logic to link your personal battery issue with T-Mob discontinuing the phone. T-Mob has a good number of Android phones coming out in the near future, with T-Mob really ramping up their support of Android devices. So its been very reasonably speculated that they are discontinuing the G2 in order to make room in their lineup (and stockrooms, etc.) for the new phones.
I get a full day of moderate usage on my Vision, and can get close to 2 days with low usage. That's very typical for a modern smartphone. I usually get in the range of 2-3% battery drain per hour when the phone is idle. And that's with WiFi always on (even when not connected to a WiFi network) and auto sync of Gmail and HTC stock and weather apps. You haven't mentioned how long "overnight" is exactly, but I'll assume 8 hours or so. So your phone draining from 40% to dead overnight seems unusual. WiFi typically uses less battery then the cell data network, when WiFi is available. I suspect there is something else going on, besides just being on WiFi. If the cell reception is dodgey in your area (or fringe 3G reception), this might run the battery down (even if you are on WiFi) as the phone is constantly searching for signal. Or your radio may be mismatched to your custom ROM. Or you may just have a bad battery. Also, was the battery drain any different when you were on the stock or other custom ROMs? I personally haven't witnessed the battery drain to be significantly different across the ROMs I've tried. But that seems to vary, as there often seem to be people complaining about this or that ROM causing more battery drain.
The reason I thought it might be a hardware defect issue is that my wife and I got G2's at the same time. I rooted mine and have been running CM6.1.1 for a few months now, and my wife has kept hers stock. However, the battery issue hit both our phones at almost the exact same time.
It sounds ridiculous, but conspiracy theories are fun to play with. The fact that I've been rooted so long, and it JUST happened weirds me out. Add my wife's phone to the equation, and it's even weirder. I kept my phone on WiFi and 2G networks only last night (yeah, about 8 hours), and the exact same thing happened.
Maybe I should just get a new battery, I don't know. But I do religiously delete apps I don't use and make sure the ones I do use are syncing as minimally as possible.
Does anyone know what app is the best for turning on WIFI based on your location?
I don't know about best, but I've been playing around lately with Profile Valet. It's free, and you can setup different profiles using all kinds of different qualifications. You can set it up using locations as well.
I'm sure someone will suggest Tasker but it would be overkill if this is all you're wanting to do. I used to use Wapdroid for turning wifi on and off and it worked really well for me.
Totally gonna give Profile Valet a try.
Locale.....
here is a question:
why have an app/service running in the background, with access to (i.e. enabling) GPS for location, to do what you can do in a second by using the power control widgets?
100% of the time I turn wifi on and off by location, as you want the app to do. except i do it myself, all i have to do is drop my notification bar down and press one button...simple, and nothing running in the background or gps eating away at your battery
profile valet has a lot of potential but it didn't work that well for me.
I have not used it in a while but it may have gotten better

Because I don't want to do it myself. When I walk into my office (which has crappy Sprint coverage and a locked down WiFi network) my WiFi shuts off, my roaming kicks over to Verizon, and my ringer drops to vibrate. The moment I walk out of my office my ringer comes back to life, my WiFi restores, and I jump back on the Sprint network.
Yes, I could do that myself with a few clicks... but why bother when a program exists which can do it for me.
I've used Y5 for quite a while. It's free in the market, does exactly what you want, and it works very well.
been looking all over. is there an app or anything that will give me a run down of what apps are accessing my wireless (wifi or mobile) data and how much they use? my battery life has been really low over the last 3 weeks (6 hours on standby) and all of a sudden I'm only down 15% overnight with wifi on.
there was a nice app that did all that and locked out what you wanted but that seems to be gone and I heard it was bricking phones.
or am I totally way off the beam here.
not sure if this will help but there is an app built in to settings-data usage. it shows what and how much an app has used. gives an option to restrict background data. if you hit the menu button you can pick to show wifi and mobile data. as far as a stand alone app from market, not sure, never looked for one.
Hello,I'm looking for an app that:
1.Enables WiFi when there's a network available (based on location or checking periodically every hour for example) and disables data the moment it connects.
2.Enables Data the moment I lose WiFi connection and automatically disables WiFi.
Simple,but I just can't find such an app.Most of the just switch on WiFi using location based rules but also leave Data ON.
Looking to maximize battery life without having to keep switching WiFi/Data ON or OFF myself.

Im pretty sure you can do that with tasker. Its a really cool app, you should try it out. Though it is quite complicated and not for beginners, good luck
OK,thanks.Is there any guide on how to get it to do what I describe in the first post?

Hello all, I have been using the d2spr for quite some time... without mobile. I have no service on the phone and have no problems using it as an esspresso device like my p5113 tab 2. On my tab two there was a thread about removing the cell from the device, which I will more than likely have to look up again for that device. Is this possible for this phone? Anyone have any experience removing cell from the phone. I have read that searching for signal reduces the battery life, and I have yet to try it on the phone. If anyone can give me any pointers on this would be great. Also if you know which files to delete would save me a crap load of time searching for it.... thanks in advance...

are you basically trying to use it as a galaxy player? (i.e. an android version of an ipod touch?) if so, ive just put mine into airplane mode and turned wifi on manually. It greatly improves battery life as its not using the cell radio.

not exactly I use it as a voip phone and remote control as well as play various games, though there is no service on it, it shows the mobile connection. With the tablet it was a wifi only tab so removing cellular feature from android really increased battery life. Though I was not sure if it would work the same on the d2spr... not quite sure where to start though so thought I would ask, but thanks for the alternative, I am not sure about using airplane and wifi together as I have not tried that before.

gotcha. well, if youre using strictly voip, then the airplane mode and then turning wifi back on separately will work very well. like i said, ive done that with other devices and it substantially increases the battery life. Give it a whirl, what can it hurt?
Just an update with the steps on what I did.. as well as the results. With rooted device I deleted the 3 folders telecom, telephone, and another that starts with a tele that I can not think of. They are located in system/priv-app folder on root of system. (Using root explorer) After that I reboot, and all is working fine with no cellular at all. I have been letting it sit just to see how long the battery lasts on standby. So far I am at 28 and a half hours... I still get notifications and wifi works smooth. In the battery section in settings it currently reads charge remaining 8 days. Anyone with no service like me might want to give it a try... if something does not work all you have to do is re-flash what ever rom you had and that will put the folders back. and install cellular on the phone again... I would say that is the number one battery drain of the phone next to the display...
Day seven of my battery test and So far it appears that without cellular on the d2 you can get up to 10 days of standby charge. I did not use the phone at all for anything but to check status. Also, If you notice the small change in the curve, it is because it downloaded updates. It was connected to the internet the entire time...
