One reason that we all are having pretty different battery time (it seems so) maybe could be the reception. I talked with Samsung support a while ago and they said that it drains more battery if the telephone constantly are seeking for reception. I myself have noticed that my bars are jumping up and down most of the time. And my battery lasts for about 24 hours (not using the phone extremely much). This is was the supportguy said:
"It could be the simcard that constantly are seeking for better reception, then it will drain extra battery and this can't be affected by a setting in the phone or so."
What do you think about this? The question is what to do about it...
I think that it's not new and it's true for all the phone ...
If the reception is bad the phone will increse the power of the antenna to get a signal and will drain the battery
Nothing to do in order to avoid this ...
If you have the problem with an other phone and the same simcard , the guy of Samsung is partially right ( I find it is an easy way to explain the relatively poor battery)
Now if the problem is that the 3G network is weak and the 2G good ... you can switch off the 3G so it won't go from 3G to 2G ... which could also drain the battery I guess

OK, I know there are numerous threads about battery drain etc etc but this is something slightly different,
Look at my sig for what i am running.
Basicly, I can get around two days of battery use out of my HD2 which i am happy with but i have noticed that the past few weeks i have been out at a cirtain night club and noticed when in this night club the battery drain is rediculous, in just 6 hours my batter went from 100% to 7%. Its happed that last few times ive been there, does anyone know why this may be?
In locations with lower signal quality (reception) radio is pumping more juice (battery) into GSM module to achieve better signal quality. My bed room has all 4 walls made out of reinforced concrete and if I take my HD2 with me to bedroom, in the morning I have 10% less battery compared to situation where I left it in living room which was better signal reception (big windows=more signal bars).
Basement location are also known as locations were mobile phones are struggling to achieve decent signal quality.

thats exactly what someone said to me earlier, it makes sence now i've heard it in that aspect.
Thanks for the reply.
I read something about how if the phone is set up for 3g, and there is a solid signal, it takes less juice than if its in gsm mode. But if there is a weak 3g signal, it takes more juice trying to find a better 3g signal. and so in those situations, its better to put it in gsm mode and keep it with a better G or edge signal.
Or something along them lines!! you may want to your phone in gsm mode when you go clubbing, see if it helps

im on it tonight, so i wil give it go.
cheers
+1 yea i agree just change the band settings to gsm this way the phone doesnt keep trying to connect to a poor 3g setting this will eat the battery like u said
Also if you have bluetooth on constantly in a club location you will get the vast majority of other phones in the place trying to make a connection irrespective of whether you are discoverable or not
still a larger than usual drain but changing the setting was cirtainly noticable.
thanks
I think you will have to experience some sort of drain regardless as there is limited signal in a nightclub, you cant really avoid that. I guess since its dark, you can put the birghtness of the screen all the way down, as said earlier, make sure bluetooth is off, erm, disable data connections?
Also, have you given your battery a full discharge, then recharge? You can get a much better battery life once you do that
Just installed JuiceDefender and I am now getting ALOT better battery life. I also don't think signal effects it because I am in a low signal area. One underneath on the widget is time since last unplugged, and you can see in notifications area the %'age of battery. Have been playing music, browsing internet ect, just using it moderately.
i36.tinypic.com/73ed10.png
Best record so far before getting down to 10% battery life is 25 hrs 48 minutes.
Sheeeiit. I'm lucky to get a full 12 hours on a single charge. So far. Only been through three full battery cycles so far.
2 days without problems.
Surfing, calling, WiFi, playing games, camera.
With really heavy usage like massive calling and browsing, it's was drained in one day.
Not long ago, first day low usage (FM radio, a bit od camera usage, couple of calls), lasted three days with 20% left.
nahhh ... i guess u r using a Mugen Power 3200mAh extended battery
otherwise impossible ..
wat firmware, rom, lagfix , progs are u using that gets u near to the end of the second day??
The biggest battery killer is 3G. Turn it off when you don't need it and you'll get quite nice battery life boost even without installing annoyances like Juice Defender. With 3G, my battery lasts hardly a day of light usage. On 2G, I can get two, maybe three days of light usage. Most of the time I don't need the 3G speed anyway, 2G is fast enough for a lot of things.
You might also try deleting battery stats and/or leaving the phone to turn itself off and then letting it charge until it tells you it's fully charged (you may turn it on after you've connected it to the charger, but not before that!). That way you'll calibrate the battery meter to your battery capacity properly, so it won't lie to you.
Oh yeah, and contrary to battery theory and logic, your battery WILL improve quite a bit after a week or two. Three cycles is not enough. Just be patient, give it time.
how do you switch from 3G to 2G? noob here.
Settings, Wireless, Mobile networks, Network mode - GSM only is 2G only. WCDMA is 3G.

Stock battery, G7.
You can see in my signature which ROM I am using, it's stock JG5 with no lagfix.
First couple of days since I bought it, I was very disappointed about battery life (previous HTC Touch HD lasted 2-3 days).
I came so far that I set wallpaper to black and even then it didn't last much more than one day. After some time battery life extended and it became quite better, even with Nexus live wallpaper.
3G is OFF in my case, I am mostly on WiFi when I need connection, but GPRS / EDGE are always ON.
I use 3g and battery is ok unless I play games.easily last 2 or 3 days on standby with a few short call s
1h Or 2 With games lol
I have quite bad 3G reception at home, living out of town.
At work it's ok, but I rarely need 3G so there's no problem.

Part of this depends on how your carrier acts. If I turn off 3G it means I can't use data, I can't sync etc. Sync & applications launching and background data is a bigger battery drain...multiples higher than 3G in my guess. EDITAccording to GSM arena, my 2G/3G talk time was way off, but I think their data is old. I'll remove it for now and replace it with "Up to 750 h (2G) / Up to 576 h (3G)"...it's not sooo much the network as what is going on when you might be connected to that network.
edit 2 GSM arena seems to have the most recent info, I thought they were approximating this from their test units.
Just fyi for those unaware.... Bell is a 3G only network, nationwide. You can't disable 3g on Bell and still have data.
Sent from my GT-I9000M using XDA App
I'm also using Juicedeffender and my battery live improved a lot. Now I can run the phone 24-30h without charging.
I know there have been many threads like this but I'm just looking for clarification as this is my first Android phone. At my house I usually get the Rogers H speed with 3/4 bars. When I browse the Internet for just an hour, 15% of the battery has been drained. Is this normal on these speeds?
I plan on leaving an IM client on 24/7 and using GPS/maps daily, so I am a bit worried because this may not last the entire day. I could switch to EDGE when I don't need it but apparently I heard that will disconnect once I start a voice call (and want to keep my IM on always). I checked my battery stats and apparently the cell standby (H) is taking most of the battery.
I am using CyanogenMod 6.1.1 with stock radio from Bell. I'm going to try to see if SetCPU makes a difference. And is there any program that can limit the HSPDA bandwidth so less battery is used? Thanks.
call *#*#4636#*#*
If you are at home or in a Wi-Fi accessible, Turn ON wifi - it uses wayyyyy less battery than the phone radio when it comes to Data....
you could get a extended battery.... Mugen Power has one for 1800 mAH and its the same size as the stock battery so no need of a bigger door.
What is your screen brightness set at? The screen is one of the top battery drain culprits. Try turning off auto-brightness, and turning the brightness down to as low as you find tolerable (depending on personal taste, and the lighting conditions in the places you use the phone the most). I recently just lowered my brightness to 35% (still plenty bright under many conditions) from 45%, and already noticing a significant improvement in batter life. Battery usage of the display dropped from over 70% to 45-50%. I haven't had the brightness set this low long enough to see how it translates to hours/days between charges, but we'll see how it goes . . ..
my battery life is retarded. probably less than yours. i swear i think i lose 1% of battery per minute of web surfing. battery is fine if you do not go on the web and have 2g on all day.
Yeah, it's pretty bad.
But that's the same for most smartphones nowadays I think...
Back to the days of game gear, the battery muncher.
6AA = 5 hours of gameplay.
I just bought some Chinese 1500maH batteries on eBay and I don't know if they're actually 1500maH. If I play with my phone a bit, I get 50% after 8 hours at work. Yikes!

Assuming the screen was on the entire time, 15% drain for an hour of web surfing sounds pretty good to me. The main battery eater while using the phone is the screen, so I doubt messing with your connectivity is going to drastically change your battery consumption in this usage scenario. Changing connectivity to Wifi or EDGE would probably help more during those times when your phone is off but your phone is still connected to the internet.
On a side note, I had terrible idle battery life when I was using CyanogenMod 6.1.1 on my Desire Z. When I was using my phone, battery life seemed normal. But when the phone was on standby, it seemed like my phone was running even when it was supposed to be on standby. I suspect it might have been SetCPU constantly polling in the background. I switched to Virtuous and didn't install SetCPU/didn't do any overclocking and my life improved literally threefold.
After reading up on many many posts on different battery life reports and different setups, I decided to play around with my HD 2 again and tried a different approach. You see, in common real world situations, a phone in GSM mode always, always save more battery than in 3G during standby. So all this while when my phone is on pure GSM the battery lasts only 10 hours even on standby, I decided to go against all laws and switch on 3G even though my spare SIM has no data plan...
so as of now after more than 12 hours on standby, the battery bar is still full... I am quite amazed/shocked that the battery eating bug is really caused by GSM mode, here is my setup,
3G on (reception is 3 bars, this is true 3G reception in my area, not roaming)
Data on (but sim has no data plan)
Phone on standby so display is hardly on
Phone is stationary and will not be moving around for my tests
I will report again after 48 hours of stationary tests

thanks for the post, did not realise someone else has found the perfect solution... I must have been away from my HD 2 for far too long lol
Hello.i am getting horrific battery life coming from my radio..the phone seems to struggle with signal in places where all other phones excel..in my house i get full signal, but if i go 1 floor down it suddently drops all signaland have to wait 15 minutes to get it back..i have tried jve,jvk,jpy and pretty much all european radios..
my location is athens greece and my provider is vodafone..i wouldnt mind it so much if it were only speed drops on 3g (whihch is not the case, i get great dl speeds in good signal areas), but this way it kills my battery..im losing 12% on standby during night time without any data connections on..
p.s it is not app/rom related , i have checked multiple times with spare parts/juice plotter and i have no wakelock issues..
rom : darky's 9.5
kernel : speedmod latest
current radio : jve
i have exactly the same thing, in 3g/hsdpa the battery goes down like hell even if i have no data transfers, wi-fi is crappy also very weak reception comparing to iphone 4, in the same network (vodafone romania) iphone 4 will get about 2 days of standby in 3g network while galaxy s has 8-10 h with about the same amount of usage, galaxy s is a very good phone on paper put in real life it is not even half as good as iphone 4. and i'm sorry for that.

lol yes...and i am use to cm7 g2 battery life that can go as far as 4% idle consumption /24 hours..this is really frustrating..if it were dependant to my usage i could deal with it,but this is just plain ridiculous..
