what is better to use... when it comes to battery consumption...
wifi or 3g?
and is there a big difference in speed?
sorry for the newb-like question...
Wi-fi is better for battery life, and its usually faster than 3G

I found, according to Juiceplotter, that my phone dies a tad bit quicker when I'm connected to wifi at home as opposed to 3g. Funky but true. Slopes of wifi usage decrease a lot quicker than the slopes for 3g usage.

I was losing 30% every night with my phone sitting with the screen off and wifi set to never sleep. Last night I disabled the wifi and lost 3% over 8 hours even though I was only getting 1 bar or signal and have autosync on for weather, facebook, email. I am going to try to leave wifi on tonight with it set to only stay on when plugged in and see how much it will drop.

I agree setting wifi to never sleep will kill your battery quicker than 3G overnight. I use Wifi when I am at work because it is faster, I am not 100% sold on the idea that it uses less battery than normal data. Especially if you do not normally use a lot of data.
The battery life on my Desire is horrible, and I would like to acheive some of the great battery performance I've been reading of other members. I've got LeeDroid 2.1a A2SD+ ver., with the 38.44 radio (I installed older versions in hopes of acheiving better battery). I am now getting far worse performance then when I had new versions of LD/radio, because "something" is draining the battery. ie. Before, I'd get 15% loss per hour during the day, and 1% loss per hour at night during my sleep, with the screen and wifi ON, (using GentleAlarm night clock, which shows the time but on a dimmed screen). Now, I have a 75% loss during 8 hrs of sleep! I even installed "Juice Defender" (Pro ver. with "Ultimate Juice"), which turns off wifi for a few hours, etc. It did nothing to improve battery life, or possibly made things worse. I tried uninstalling some programs, but nothing's changed yet. How can I find out which program or configuration is causing the battery drainage problem?

Wi-Fi drains faster than anything, if you're not using it then shut it off! Also, 15% drain per hour during the day and 1% at night isn't that bad. I would switch back to your first configuration. Maybe you're not taking into account how much you're really using your phone?
Well I'm comparing battery performance when I am NOT using my phone at all (during my sleep), and its night and day. When I was getting 15% per hr, 1% loss at night, that was with wifi ON (ie. JuiceDefender was not installed then, and it cuts off Wifi at scheduled times). I'd like to switch back to my first configuration, except that's my prob lem: I have no idea what that configuration was exactly. Lots of programs installed and uninstalled since. I'm going to take a look at a few apps though that might help me understand how to control battery performance.
OSMonitor from the market. See what may be hammering your CPU. Real time read out of CPU usage broken down by each process.
good day. From my Fascinate using the XDA app.
anyone feel as if their battery life sucks? I do have 4g on at all times but I didnt think it would make that big of a difference in terms of battery life.
See my post here:

Try installing a monitoring app and see if your init process is hitting the CPU hard. I haven't heard from any other mt4g users with the same problem, but lots of.desirehd users have it.
I also have seen my suspend process eating 50%+ CPU when the phone is locked/screen off. Haven't found a fix for that yet though.
I'm getting a full 24 hours of heavy texting, moderate phone calls. Battery life is better than my magic... im having no issues.
Yes, I woke up this morning and my phone was already blinking and battery is on 8%. I left it overnight with more then 60%
A big problem also is that SetCpu cannot force the scale. If limit to 768 Mhz it still scale to 1024. So not I am sure that my ScreenOff profile with 245 Mhz DOESN'T WORK!
THAT'S SUX!!!

Weird I leave my phone at full overnight and its still at full when I wake up.
Try disabling the preflock that might help before I did that it wasnt scaling properly now afterwards it is.

I have frozen a few apps and use advanced task killer every time i start up 9a lot of apps come on at start-up).
The result is pretty good battery life. I have only gone dead when I had a few apps (like GPS navigation) running in background and forgot about them.
I'm having 0 issues with my battery. It easily beats out the battery life on the Samsung Vibrant I had.
I'm having issues too. My battery life today was 40% at 1 PM, and when I left this morning, it was full. I hardly even used the phone except to check email :/ I have brightness on auto and wifi off. Not sure what the issue is.
My battery life has been really good. A typical cycle is charge to full and disconnect power at 10:00 pm. Up at 6:00 AM, battery is still on 100%. Today my use has been moderate to heavy. It's now 2:30 PM and I have 68% left. I typically have around 30 percent left when I put in back on the charger. I'm happy with that.
Wifi, Bluetooth, GPS, etc., are kept off until I use them. I do however leave Background data and Auto-sync on all the time.
I turned on USB Debugging as recommended and my battery life is much better. Right now it hasn't been charged in 9 hours and is at 79%. I've downloaded 2 apps, updated 3 apps, sent multiple emails, light internet use, and 3-4 calls. I'm unrooted and don't use any task killers.

That's awesome. I'm going to turn on USB Debugging mode and see if I can squeeze a little more juice out of it.
I have had intermittent battery-drain issues too. On Saturday morning my battery went from 100 down to 76% in a matter of an hour or two with hardly any use. I did a restart and it seemed better. I've also gotten into the habit of restarting my phone once a day, right before I take it off the charger in the morning. I've turned off quick boot, which I read somewhere in the forums can affect battery life. It's been pretty good the last few days. I'm at 68% now off charger for 9.5 hrs with moderate amounts of wifi, web browsing, email, and 3G network usage. I'm new to android devices so I don't have much to compare that to, but it's working for my schedule.
heavy user - fully charged phone at 7am ... start using after 7:30am
check emails, fb, txt, barely to no calls.....phone will be down to about 20% at 1:30~2pm....
yes the battery is lame...but this is a known issue with HTC...the 3.8 screen drains a lot of battery also the constantly searching for HSPA+ and 3G...
I do notice when screen is off....this phone still drains battery !!! bad =(
left over night at about 65% left in the morning I got red blinking led saying phone is below 10% .... 50% gone!!!
I think restarting the phone after a full charge is a good idea....also maybe turn off quick boot?
*update* yes I found that when you have a bad signal and it's jumping between E and H ... this eats up battery
also installed Advance Task Killer (for froyo) this helps~ now from 8am my phone can last until about 4pm getting about 3~3.5hrs more life
Mine lasts all day with everything on, playing games, email, text, etc, etc.
It is great, best phone I have had. Not sure what the issue is unless it is root.
It depends where you live.
If you get a good antenna signal, your battery will last.
At my apartment signal is low, so phone is constantly between UMTS and GPRS, plus phone is trying to hold H, so that drains the battery.
My signal strength parameters:
between -101 dBm and -107 dBm (where -110dBm is the edge of the signal/loosing signal)
3 asu and 7 asu
When I got my S2 10 days ago, I followed advice to help with battery life by switching off wifi and NFC. Battery life has been very good (currently have 62% after midnight having taken it off charge at 7am). I charge every night so I could turn wifi on but what would the benefit be? If I go upstairs in my house without taking my phone the BT connection drops. Would wifi prevent this? Is it an either/or BT/wifi connection or can they both be used at the same time?
The point of wifi is to keep your connection when you loose bt connection. I question how much battery you save if you phone is constantly searching for bt connection. I have wifi and bt on all the time and have about 48% at 11 pm
Hi, i have Note 10 Exynos Version, phone was fully charged (100%) at time i was gone to the bed around , i turn off all the futures like wifi, NFC, Etc... i shocked when woke up and found battery is on 74%, i had s7 edge and never face sych iss5its hardly uses 3% max un standby, sometimes My note 10 drain 18%, 20%, i had checked everything but couldn't found reason for battery drained in standby, not installed any fancy app, its not show any background uses of any app, i dont know how to attached screen shot to this thread otherwise it will clarify more about issue..... help me to resolve ..
Sync and Bixby routines are major candidates for overnight/standby battery drain.
Even i face the same overnight drain issue which never happened with my S10+, but not as much as 24%.
It has also got to do with your network signal strength in the place were you live.
Hi , the point you mentioned about network signal strength seems possible culprits, i barely get 1 to 2 bar signal strenth (idea network) at home, secondly sync and Bixby routine was already turned off, is it possible that poor signal strenth should tole that much on battery? I had s7 edge and its it's never drained that much battery even at poor network signal strength

Look under your battery settings, should show more detail about what is consuming what amount of power and go from there.
Hi, if i turn-on the flight mode at night before bed, phone won't drain battery at standby, its draining graph stayed flat at night, so i assumed that main culprit is poor network signal.... by the way can u enlighten me how to add/attached screen shot herewith if i wish to? As i dont found any option menu for that....

As for your battery drain, the main culprit is always bad battery signal. So maybe try locking it to 3g and try it out.
Sometimes when the network is bad and the phone wants to sync, it will fail and keep trying. It's an issue which plagues samsung to be honest. Had it once as well on my note10.
