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.
I live in an area with poor mobile signal and consequently use a Vodafone Suresignal box. This creates a a micro cell that allows my mobile to recieve a good signal. As you know these boxes rely on a broad band connection to make things work.
What this means is that the distance to the Suresignal box and the broadband modem differs by about 6 inches. For this reason I am perplexed at the significant difference in battery drain with and without WiFi on.
My phone is a Samsung Galaxy S using onecosmics release 4.2 of ICS with the devils 14.2 rom.
If WiFi is swithced off then I get about 8-12 hours of battery life in idle. I.e. the phone is connecting with the Suresignal box by 3G.
If I switch WiFi on then I get over 2 days of battery life with the phone in idle.
I have tested this several times and the result is consistent.
Why would this be the case? I would have expected that WiFI would have been the battery burner not vice versa.
Does this observation help anyone? Is there a techincal explanation for the above observation?
My cell phone with Team ICSSGS RC 4.2 behaves that way too. Is it normal that wifi is more economical than 3g?
ROM: Team ICSSGS RC 4.2
Kernel: Semaphore ICS 0.8.1
Modem: JVU
I believe wifi is a little less battery hungry than UMTS. I always keep an eye between the two whenever I change roms (Stock/CM7/MIUI/ICS) as I am a heavy data consumer. Also note that Wifi policy may have been set to turn off when the phone is idle, or never. If former, it will turn wifi on if your screen is on and will essentially not putting wifi to sleep and loose connectivity.
Here's how I scale the consumption, with topmost is the least battery hungry
1. E (edge data connection)
2. Wifi
3. 3G (UMTS/WCDMA data)
4. H (HSDPA/HSUPA)
JVU the modem is very heavy in battery, the modem JPY is less greedy. It depends on the modem. But 3G or HSDPA will always be more hungry than the wifi.
Indeed, WLAN is less consuming than 3g.
As a suggestion, when you are not using WLAN or you are not in range of it, you may switch to 2g connection ( Edge ). Although it's loading way more slower than 3g, if you use it mainly for emails and not for browsing, you will not see any difference at all.

I have the same results
offcourse 3G has more battery drain
Wifi is better on battery than 3g, if you are connected to 3G and not using Wifi Turn off the Wifi, because your phone keeps looking for a wifi signal and that drains battery faster. But if you are in a wifi range always use Wifi over 3g.
i had DesireHD i9000 i9001 in my hands to play with ... 3g is always the biggest consumption regarding internet connection.
Hey all,
assume that I have 3G flatrate with no extra cost. I wonder myself, if WiFi or 3G consumes more power of my battery? If WiFi would consume more power, than I would switch to permanently use 3G also at home.
Hope to get some helpful answers from the pro's here.
Thanx
3G, by far.
3g>wifi>2g

3G consumes more power of your battery than WiFi.
thanks to all. So I will keep WiFi enabled at home
It depends on CDMA or GSM. CDMA is pretty battery efficient and IMO Rev. A EVDO is the best for battery. If you have a strong 3G signal where you live and get good speeds then you may get better life than wifi, but that is rare. More than likely wifi will be better. Now on GSM 3g will be worse but EDGE will be amazing.

Right on. Signal strength is the real key. If your phone is constantly polling on 3G to get a signal lock, it'll drain the battery quickly. With a decent signal, it doesn't drain as fast. Same goes for Wi-fi. With a good signal, definitely better if you're downloading a lot of data as it takes much less time. However, if you're out of range or at the edge of it, it struggles to keep a signal lock and wastes battery. So, if you're at home just lounging around, have a strong 3G signal and aren't downloading much, it's best to go with 3G. If you have a bad signal, or download a bunch, go for Wi-fi. It's more just a balancing act than anything to get the best battery life. Also, make sure the wifi is turned off when you're not connected, or it will be constantly searching for a connection which also will lead to battery drain.

Nah, not in my experience. I live in an area which is well-blanketed with EVDO 3G, I literally have never been anywhere in the normal course of work or home that has less than 4 bars and 3G lock. Also, my house is covered with wifi, not as thoroughly but plenty to maintain a connection wherever I am in the house, and full signal in the rooms where I spend the most time for sure. Also, until recently, I had wifi at work, they just locked me out of it in fact (because they're facists).
In my experience, I always get FAR BETTER battery life using wifi over 3G as much as possible, even though I have great 3G signal strength 100% of the time and not-so-great wifi coverage. It seems like that wasn't the case with other smartphones I've owned in this same situation, with both Verizon and AT&T in the same locations and with roughly the same coverage (much worse with AT&T, though, of course.) But, with this Droid 3 running the stock ROM rooted, just a few apps like IM and BluetoothDUN frozen, with great 3G and less-great wifi coverage, I always get much better battery life from a day of being connected to wifi versus a day being connected to 3G.
Now, I manage my wifi switching very well too, though; I use Timeriffic to turn mine on and off every work day on a schedule, meaning it's never searching for wifi networks unless I'm geographically in a place where I know there is one I have the connection credentials for. If I left it on searching (and not connected to) wifi all day, I'm sure I'd get a battery life hit, which if I wasn't paying attention like I do would look like wifi eating the battery.
Ciao!
You may have a good wifi router. Mine sucks so that may make a difference. We have a Motorola SBG900 modem and I am always losing signal.

I usually turn of my mobile data, and connect to just wifi when there a network available.
What consumes more battery? If speed is not an issue.
Thanks

I had a Samsung Epic 4G (the first line of Galaxy S) and on that, wifi consumed less battery than data, but on the Note, I am experience the opposite.
I find that wifi drains my battery faster.
If I disable wifi and am connected to 3G, the battery lasts longer.
If you use wifi to surf net, battery time will last longer. If you use data mobile like Hspa, you can see the battery drain very fast. (6 months of monitor with this)

WIFI always use less battery the radio doesnt have to do much work since the router is within a close range.... mobile radio does much more work and consume mote battery than wifi...
Wifi power usage depending of type of wifi (2.4G or 5G), router settings and signal.
2.4G is less then 5G type. This is because more power will need for higher freq.
Router setting will give impact on your connected device to your router. Go to the wifi advance router setting and set optimal for speed and less power usage wifi setting such as Beacon Interval, RTS/CTS Threshold,Fragmentation Threshold, DTIM. And last great signal great battery life.
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.

Tasker does the same and it is way cheaper.

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.
and its free

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.
