is there any way it can help my tilt from preventing battery drained..it was fulled charged at 11 pm (only instant message was still running but no messages), woke up at 9am and theres only 53% battery left. i barely listening to music but when i do it killed faster.
changing radio can change the rate of battery drain
What type of Messaging were you running? What program? Some keep a continual data connection & if you're in 3G territory that can easily account for that battery drain.
I used to leave HSDPA on and auto check email every 10 mins, my battery only last more than a day even without any phone call in this time. I was then disabled the 3G + HSDPA, just leave the GSM on (changed this in the phone's band), my battery now last about 4 days and still have some power.
Your data connection kills your battery severely, this may be what caused your battery drain 50% over night.
my 3G is always on. I have internet and everything. does 3G interfering my internet connection?
u can get very good battery life when 3G service is deactivated.
also make sure disable wifi, make sure when not in use no application will auto on the wifi...
make sure device lock is set to lock all buttons.

what does HSDPA do? i turned off 3G already. i pay unlimited monthly internet so are those things that i turned off interfering anything from it? i Disable HSDPA already and my internet still connecting. sorry for many questions but im pretty new at this tilt.
Just make sure the icon and or mobile operator name has no 3G indication. Yes u still can get connected via internet, which is through your GPRS, which online activates when as you wish. 3G is passive mode whereas GPRS is dynamic.
hi,
i was wondering if there is an app which will automatically switch from 3G to 2G when i turn of the display. When the phone is in my pocket there is no need for the 3G eating my battery.
that would be an amzing app BUMP BUM BUMP
It indeed would be. I'm on it.
EDIT: Then again, switching from 3G to EDGE and vice-versa is resource/battery heavy in heavy and will probably leave you without network for a while. I'm actually going to say it's not worth it. If I create it, I'll post an initial version up here for you guys to decide (no 3G frequencies for me).
Edit: it seems as though there's nothing in the api about switching network state. Looks like a root app (if it's even possible) would be required..
Edit2: This is probably impractical. For example, if you answered a call, you would be disconnected from the call immediately. Besides, the G1 is rated as having more sleep battery life under 3G than GSM.
How does being on 3g even waste battery when your on idle? what Syncing with gmail? i would think the constant switching would waste more battery
I guess you could do it with Tasker. I got that app in ADC2 and it's amazing what you can do with it.
I guess it would be very impractical if you would get disconnected everytime you answer a call from a sleep state. I havent compared the battery consumtion between 3G and "g yet, but i imagine you could save quite some. m not only talking about the Synching, but mainly Chat clients which run in the background. There is no need for them to run over 3G.
I have a ATT type Nexus One (not Tmobile), unrooted, with latest froyo.
The life of the battery in 3G mode vs. 2 G mode is astonishing...pretty ridiculous.
I'm searching but can someone tell me if there's been any fixes or advancements in regard to this problem?
When at home I use wifi as much as possible. I leave it on 2G but really, I can't take the slow speeds of 2G, but 3G setting is suuuuuuch a drain on the battery that it seems unreal.
i've had nokia's and more in 3G, my wifes iphone is 3G... and all of them had nearly more than double the battery life.
I hate the voice quality of 2G, I'd love to be able to just leave at 3G, but it's merely hours before it's nearly drained set on 3G. it's got to be a problem (and one that hopefully can be fixed).
Why would 3G setting be sucking THAT much power (decent-strong signals too here)?
Love my nexus1 and I'll live I guess but this problem...it's a bit much.
Any news on this issue, or other things I can consider or change/try to help this? (3G)
thanks
Set your WiFi sleep policy to NEVER. Even thought you're using WiFi at home, whe nthe screen goes off the WiFi shut off and 3G kick in.
Menu>Settings>WiFi settings>Menu>Advance>WiFi sleep policy>Never.

Oh very sorry, I should have said I did set this to never and saved changes.
In fact, I think I've set it 1000x now btw, over some time it STILL always disconnects from wifi (might be router disconnecting though, perhaps I should set an IP manually to solve this??).
GPS and BT are always turned off until needed as well (used very rarely anyways btw).
But when I'm away from home for example, I turn wifi off and test the difference2G vs. 3G and the difference is waaaaay too much, 3G just CHEWS at the battery no matter strong signal or medium.
I find it hard to believe 3G really has to eat up that much battery when set compared to 2G on a Nexus. A little bit to nominal ...sure, but not like this (say like 4-6 hours if i left it 3G for a day with little usage).
What's really happening here? Nothing from google/HTC on this matter?
Heh, i get just the opposite... out in the farmland of west toledo, im getting 2G but typically GPRS and that rapes my battery where as 3G i could go on standby for days if i didnt touch it...
What radio are you running? if your phone is constantly looking for a signal then that may be your problem...
I have the same issue on 3g. Home on WiFi is ok but when I go out during the day on 3g it just kills my battery.
The reason is because android OS keeps the data session open at all times where other OS's close it down when not in use. It's just the nature of how they designed android.
As a test, one day turn off your data connection but stay on 3g and see how good your battery life is. This is how some other OS's work normally.
It's a trade off we have to make for being always connected on android.
For example voice actions need to reach out to Google's servers to work. So in the interest of speed of having to open the data session each time, the OS just keeps data open on hand at all times. But that kills battery quicker.
That's what I've found anyway.

That's because the phone is always on the lookout for a 3G signal, if you know you aren't going to get one, just set it to 2G only and your battery life will massively improve.
Hi I have had several smartphones and I've had all the 4g Verizon phone and when I connect ti wifi automatically mobile data turn off or at least icon disappear from status bar but with the revolution and with this bionic that's no happen somebody can tell me why thanks

Do you get the color change as described in this thread? http://forum.xda-developers.com/showthread.php?t=1261253
Mine does this
My bionic also stays connected to the mobile network when wifi is on and sometimes it will pull from the network instead of switching to wifi. the radio is all messed up on my bionic.
Well is not a mess I mean when I am connected to wifi my phone use wifi internet instead the mobile data but I guess with wifi n mobile data use more battery I guess I don't know the revolution is like bionic the same happens

I see this on mine as well. I know some people have indicated that it is not really connected to 3G, here is what I'm seeing:
When Wifi is turned on, the 3G (or 4G if lte is enabeld) sometimes stays on. Sometimes it changes to white (indicating that it may still be connected, but not syncing to google through that connection), sometimes it stays blue, and once in while it actually goes away, but not often.
Some other threads seem to indicate that this is just a display bug. However, if I analyze my battery stats, I think the connection is actually staying on. Here is what happens:
* With just a plain 3g/4G connection and no wi-fi, if I look at the battery stats for Cell Standby, the "time on" increases as expected. If there was a period when the cell signal was dropped, I will also see the percentage ot time without a signal.
* When I turn on Wifi and the 3G icon stays on, if I look at the battery stats, the Cell Standby's time on continues to increase, but not the "percentage of time without a signal" also increases. This seems to indicate that the cell signal is staying on, but it knows it is not connected and is searching for a signal. I'm not sure if this is actually eating up more battery like when you really don't have a signal and it is searching, but it is being reporting that way at least.
* If I install a widget to disable 3G/4G while on wifi, the icons go away, but I still see the same thing happening in the battery stats. This could indicate that it is still connected, or it could invalidate what I'm seeing altogether, not sure.
In any event, I'm not sure what the real story is here, I never had the icons stay on with previous devices (Droid X and X2), so I never investigated the battery stats. However, I see alot of people talking about their Cell Standby taking up a lot of battery, I wonder if this plays in to it.

yeah I don't think it's really on either. I verify this by using speed test. I know my speed at home and lte is faster. lol
When I use juice defender I disable mobile data when connected to a wifi SI icon disappear this happen with the revolution and bionic I don't see on tbolt nor charge

My 4g icon stays on while connected to wifi and stays blue. But according to speedtest the speeds reflect connection to wifi.

Mine is doing the same, but its still draining the battery like CRAZY when browsing on supposed wifi... Definitely a bug.
Mine is the same way but I can't use anything on my network like google tv remote or printershare it says it can't see anything on the network. Tried other phones and they work

It should prefer wifi over 3G/4G. I keep this page bookmarked on my Droid that shows IP and ISP name to test it.

I have been on wifi all night. 3g lights on. However, my data useage for the month have not changed. I am confident that 3g is not being called upon

My experience is similar.
Hey all,
Does anyone else notice that they get better battery life while on LTE/HSPA rather than on WiFi? I decided to leave my WiFi off yesterday to see how well the phone does while using the GSM radios. To my surprise, the GSM radios were more efficient. I also noticed that on the stock battery app there were way fewer instances of the phone being "awake". With 11hrs off the charger,1.5 hour of SOT, 45 minutes of music I had 73% battery left. To me this is solid battery life. With the same exact routine and WiFi on I have about 65% battery left. Not a huge difference but enough to where I don't feel the need to juice up during the day if I am going out at night. I'm doing the same thing today to see if it is an anomaly but so far it looks like it is the same as yesterday. Anyone else seeing this?
Variables:
Stock, unlocked, not rooted.
brightness set to 1/3
T-Mobile $30 plan.
This is in NYC which has great T-Mobile service, that being said the bars in the battery life menu are "yellow" indicating the signal is "ok"....mostly because the testing was done indoors.
Google Now enabled.
GPS set to battery savings
Scanning always available (in wifi settings) turned off.

I agree. I just turn off wifi, use LTE only.
But I have to turn on wifi when I download something or update, I have limited data plan :crying:
If I have unlimited data plan, I will completely turn off wifi
Same here today. All day with data (tmobile) and had wifi off. Was getting better SOT on data vs wifi.
Is there a way to enable/disable WIFI automatically based on location? through an app or native os function?
This probably had something to do with the n5 having only one main antennae for cellular connections. The phone isn't connected to LTE and gsm at the same time, just LTE and switches back to gsm when a call comes in. Therefore when only connected to a cellular network only one radio is on. In contrast with Wi-Fi on that is another radio consuming power. Someone correct me if this is incorrect.
I've noticed this recently but my situation is because when I was on wireless I was getting a lot of wlan_Rx_wake wakelocks. I obviously wasn't getting it when on LTE alone. I've managed find the issue on my network at home . now I have to figure out what the issue is on my hotspot. My phone has been sleeping like a bear in the winter now. I imagine a lot of people are probably getting a lot of these wakelocks. I wonder what makes this phone susceptible to it and not the other nexus devices.

10 bucks is ridiculous. I found Llama that does practically the same thing (if not identical). I've set it up to disable WIFI as soon as i leave "home" and enable it when i get to "work", as well as set up other actions (quite mode after midnight etc) within the profile.

If you're comparing lama to tasker specifically, llama does about 10% (being generous) of what tasker does. Although there's a lot of learning to be done.
I'd pay 100 Bucks for tasker

Well the nexus5 utilises envelope tracking when ring on LTE. Maybe it's doing its job... http://androidcommunity.com/nexus-5-getting-battery-boost-from-qualcomms-envelope-tracking-20131101/

An interesting question in this forum post but does this not really depend on the strength of the wifi/LTE signal? For me on wi-fi at home I can easily get 6 hours+ SOT. On a normal day with a mix of LTE & Wi-Fi I generally after between 4 and 5 hours SOT. My wi-fi signal at work is stronger than the LTE signal so I generally use the strength of the signal as a rule of thumb as to which will provide better batter rather than just the signal itself.

Hi, I just made this app:
https://play.google.com/store/apps/details?id=com.sdev.autofi&hl=en
Basically uses GSM/CDMA and GPS Locations to automatically turn on/off your Wi-Fi. The app is for free.
Note, this is my first app, so if app crashes please submit the report so that I can fix it.
Leaving my phone over night with no wakes showing it will lose 3x as much battery idling with the screen off then on WiFi.
This was using "turn WiFi off during sleep" option to test if I could further minimize over night battery loss. I lose about 3% over 8 hours of idle, but on my data connection it lost 9%.
When the WiFi turns off the Data connection turns on, and vice versa. So only one is only ever being used at one time.
