battery drained

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.

[Q] Battery drain: Wireless vs local 3G

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.

What is using more battery - 3G or Wi-Fi?

When internet access (either idle or during active use) is necessary, what is the better option for battery life?
Does Wi-Fi drain more battery, is it the other way around or is it the same?

Best option for bettery life is to leave wifi on when your in wifi area

Wifi saves more battery than 3g.

yes I agree Wifi drains less battery than 3G if you have a good wifi connection, but not if your phone is scanning for new wifi connection when you travels.
To be clearer, wifi is the best option at home or hotel room compare to DATA transfer (3G).

Thanks, I always thought that 3G needs more battery juice. Every day you learn something new.

Damn me to i always taught 3g would use less. Thr note battery still needs to be inproved.

But if you are at home , WIFI is on and the screen off - actually this happens the most time.
I marked the option in the advanced WIFI-settings that turns the WIFI off when the screen is off.
What happens then? Does it do all network stuff with the 3G connection or is there a WIFI-wakelock for apps like Whatsapp?
If it uses the 3G network would't it be better to change to 2G?
Iam not sure this helps something but iam acutally doing it like this. Always on 2G (because at home and at work i have WIFI) and only when i need 3G when iam not in a WIFI-Network range i switch to 3G.
Does someone know how Android works?

Wifi is always better than 3g
Saves battery
saves money
And in many cases faster speed than 3g
So I will go with wifi

Wi-Fi showing under battery usage while off?

I have had my Verizon Moto X DE for a few days now and have been loving it. At my work, my old gnex would be without signal for 80% of the day. With the Moto X, it dropped all the way to 10% or less (could be a coincidence that Verizon made the network better the day I received my new phone...data speeds are about 5 times faster than they were as well).
Battery life is also much improved with the Moto X with only 100mAh more battery capacity compared to my gnex + extended battery. I am wondering about the battery usage reported on the Moto X. I do not turn Wi-Fi on (milking that unlimited data), but the battery usage is showing Wi-Fi using around 8% of my battery. Does Wi-Fi enable itself on the Moto X when location is set to 'High accuracy'? Battery has been fine for my usage, but I rarely connect to Wi-Fi and only use it at home if at all (especially now that LTE is faster than my home internet lol). Is there a disadvantage to using 'Device only' location mode if you do not connect to Wi-Fi networks?

That's a loaded question.?
If you go to WiFi settings and click advance there's a setting for WiFi scanning while WiFi is off. That's why WiFi usage shows higher than average. You can just turn that off.
High accuracy will use your cell signal, WiFi signal and GPS to get a faster lock. However, if you only leave GPS on depending where you are it will take much longer for the GPS alone to lock on your location. I personally just leave it on battery saver which is cell/ WiFi if available. If you're using navigation than you have to make it high accuracy so that it can get a good lock and not send you on a bad route.

2g or wifi

I wonder what is the connection that uses more battery, 2g or wifi.
I only use the internet to update the app lockmix, then the 2g enough for me, but I was wondering which spends more battery if it is 2g or wifi

2G uses very little power in the background, but it's very slow so transferring much data over it will use a lot of power because the radio will need to be on constantly.
WiFi uses a significant amount of power even on standby - that's why WP8 defaults to turning WiFi off when the screen is off - but it's probably worth using when available if your only other option is 2G.
BTW, are you sure you meant 2G? That's archaic; 3G has pretty much entirely replaced it and 4G is become more and more common.

I only use the internet on your phone to update the lockmix application (for screen lock), the 2g is enough. I have to have an active connection, my doubt is on wifi or 2g due to battery consumption. my wifi router this to 2/3 meters away and have speed of 30 mb.

But obviously, battery drain's on 2G network, & no issue about Wi-Fi distances, but it also drain's down when background searching & attempt to connect to the network at multiple times.
