You can put your phone in airplane mode and then turn on wifi, if you want to use data and not calls, sms or mobile data. It works, I just double checked.

Help Excessive Battery Drain (Even On Standby)

I tried using Juice Defender. It seems to work (only been using for a few hours so far). But when I go to Settings page, I seem to be only able to access the default setting. If I try to set to another -- aggressive or customized or advanced, it just goes back to default the next time I see the screen. And I cannot see the "controls" tab at all. When I press the menu button I get no response.
Is this normal behavior for JuiceDefender on the Optimus V?

There is an Ultimate version that allows more customization.

I'll leave it to others who have the Free version to comment on specifics of that one.

Well, I've been getting good battery life the last few days. So far I'm able to go about 32 hours and have about 20% battery left. Things that I've found that help greatly:
#1- Juice defender: It helps manage your connection so that it doesn't use up as much juice.
#2- Advanced Task Killer: Kills apps upon entering standby so you don't have background stuff burning juice.
#3- turning the connection to Wi-Fi when you have access, it will keep the 3g from constanly burning battery.
#4- Make sure you turn off GPS when it's not being used.
#5-turn down the screen brightness.
#6- turn off "auto sync", it just burns battery.
#7- for new phones make sure you completely charge it right away. It may also take running down the battery (to about 25%) and completely recharging again a few times before you get your true battery life.
Using this, I can get 32-35 hours on a charge, about 18-24 hrs if I'm without a wi-fi connection or poor data connection area. Either way, I can get pretty much a full days use out of a charge now and that's not running it to 0 (which is bad for the battery).

I don't have any Task Killer and my battery does not drop at all when the phone enters standby (when screen shuts off due to inactivity) so in my experience task killers are not necessary.
The battery drop from screen brightness is insignificant too if the phone is in standby most of the time so I have mine at about 50%.
I don't know what exactly Juice Defender does but I suspect you would get the same battery lifetime without it. If you actively use the 3G connection to say browse internet, the battery would be dead in a few hours with or without juice defender so I am guessing your usage is light on the 3G data connection. In such case, it is much better to turn off 3G unless you absolutely need it and your battery lifetime would be several days.

Hiya... I am new to Android, new to this phone, but am depressed about the battery usage. Got the phone new yesterday and immediately plugged it in and it remained plugged in until it finally reached 100% charge. Since I haven't transferred my number yet, the phone isn't activated, so I don't know what it is doing or not doing relative to 3G since I don't have service on it yet. When I checked the phone this morning, it was at 35% charge???? It sat idle all night, or I assumed it was sitting idle all night.
I have had cell phones since the original Motorola brick and never had a phone suck juice like this one. I have an EVO 4G sitting here for weeks and still has almost full power and my regular phone that I am moving from, a HTC TP2 can sit all week in standby mode and still have nearly a full battery. Have never had to run special software or disable things to have my phones run a week or so on standby. I am a very low volume phone user but this just isn't going to cut it. I read this string, and have downloaded all the apps, but don't know what combination of things I should do as it seems there are a lot of different suggestions, but it is probably just an item or two that is the cause of this since the screen is black, brightness, etc. wouldn't be the issue.
Thanks!

yes the battery life isn't the best. even an unactivated phone will search for connections. this might be why your battery is drained. i've had better charges after a few cycles. try turning on airplane mode...this stops the search for signal. i bet you might lose 2 or 3 percent overnight.

I've tried most of the suggestions here with little to no success. So, today, I turned off my 3g, and lo and behold, it isn't sucking the battery dry anymore. I've now had the phone on for 3-4 hrs, and it still reads 100%. Before, after 3-4 hrs, it would be around 75-80%!
I guess this thing really sucks juice when using 3g. And, it's not like it was hunting for a signal, I have good coverage here in Atlanta.
Disappointing, to say the least, but I guess I'll live with it.

I found out the same thing. I switched over a few days ago to letting it use my wifi network all the time (including when the screen is off) and it's incredible the difference in battery life. I need to do some more formal checking, but I could probably go 2-3 days easy on a single charge even with moderate usage as long as I'm using wifi instead of 3g.

I got my phone on Friday and had to charge it each day. The battery went dead and the phone shut off overnight on Sunday night - Monday morning. Added Data Enabler and Juice Defender and recharged the battery. The phone has now been on for over 24 hours and is still over 50% capacity. GPS off; Wifi off; 3G off; Bluetooth off. Only turn the 3G on when I am on the net or checking email. Used the camera, internet (about 45 min); searched the Market (about 30 min) and texted about 10 times. So I am now satisfied with the battery life/usage. It works for me.

When I got my phone first it would last about 8 hours, but then I uninstalled quite a few useless apps and now it lasts for about a day. I have found the app 'Mini Info' to be very helpful when I need the phone to last a bit longer, using that app you can toggle wifi, bluetooth, gps, screen brightness, sync, screen timeout, auto rotate screen, etc. It also tells you the CPU usage and RAM all from the home screen widget.

Apps that monitor phone data usage like 3G really drain the battery!
Hope this helped.

My phone has been experiences progressively worse and worse battery drain, and I don't think it's the 3G problem.
Today, for example, I unplugged the phone (100% charged), then used it a little over the next two hours. The use probably was about 10-15 min of email & web browsing, no video streaming, no mp3 or music, and one 2 minute phone call. At the end of 2 hours, my battery was at 72%! I am running very little in the background: no livewallpaper, twitter syncing every 30 min, the built in news & weather widget, and gmail push. That's it.
I checked the 3g status and it said "0% without signal", so I do not believe this drain had anything to do with the 3g problems others are reporting.
I also have System Panel pro monitoring application history, and I don't see any usage out of the ordinary.
Any hints for what to check next?

HUGE drain on battery when searching for a 3G signal. Battery would drain in less than a day. It may be a bug in the phone.
I turn off 3G and use WiFi at home and work. Now battery lasts for days.
When I don't have WiFi I'll turn on the 3G and use it...then turn off 3G when I'm done.
To turn off 3G: Home>Settings>Wireless and Networks>Mobile Networks>Data Enabled.
Just uncheck 'data enabled' and the phone won't search for 3G and drain the battery.
It's a little incovenient...but otherwise the phone is great.

Hello all,
There are days that my "phone idle" actually uses more battery than "cell standby". I use a Task Killer, but what I find out is that maybe 5 secs after I kill all the apps, some apps (that I don't open) will show up on the list, as if they open themselves up in the background!? Is this normal, or is there a way to stop these apps from self-opening? And can this be the "phone idle" that drains my battery? Thanks everyone!?

There's a nice little widget someone else mentioned in this forum called "Data Enabler" that you can download for free that shortens the above process. I use it all the time. Just put the icon on your Home screen; tapping it takes you directly to the "Data Enabled" checkbox.

Yes, this is very useful. I keep it in the top right corner of my home screen, so it's an easy tap-tap-Home to turn data on/off in less than a second. (If it's in the top-right corner your thumb is perfectly positioned for the second tap.)
Since I don't need the phone to constantly tell me when there's a new email, it's easy enough to turn data on when I want to consciously check it (or browse the web, or whatever), then turn it off when I'm finished before I put the thing back in my pocket.
I get several days out of a charge so long as data is turned off most of the time; it only drains about 5% during the night. But I'm not a heavy user, I don't even use it as a phone very much, just a couple of calls a day. Probably goes without saying that I've also turned off the GPS, bluetooth, wifi, etc. Quick Settings and Data Enabler are essential for this machine.

I went into settings -wireless networks - mobile networks - toggled mobile data (unchecking it and then checking it again), toggled roaming (checking it and then unchecking it again), and it stopped suspend from running!!! Halleluja!
I came from draining 7%/hour to 2%/hour.

Be careful when using task killers. On Android 2.2+ devices, third party task killers can actually reduce battery duration, especially if not configured carefully. What happens is actually described by another user in this thread:
Hello all,

Is this normal, or is there a way to stop these apps from self-opening? And can this be the "phone idle" that drains my battery? Thanks everyone!?
Unfortunately, this post is over a year old. But this is normal, for some apps. What happens is that you set your automatic task killer to shutdown an app. But the app is triggered to open itself when certain conditions are met (most of which are determined by the app itself). Like Google Maps loads in the background whenever you open Google Play (Android Market). If you have it set to automatically kill Maps, but keep using Google Play, Maps keeps opening in the background, the task killer keeps killing it, and the cycle repeats. This causes your CPU to work harder, which causes it to use more power, which causes your battery to drain faster. And that's just one app. If you set it to aggressive, you could be killing a lot of system apps that Android wants to keep in the background, so will constantly reload them.
I would recommend that you do not use task killers, or use them to only kill apps like Facebook, Twitter, games, etc. And watch what happens if you do kill them. If they automatically reload instantly, or re open later without you opening them again, I would suggest you do not auto kill them.
