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

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
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.

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.

I'm also using Juicedeffender and my battery live improved a lot. Now I can run the phone 24-30h without charging.
Is it just me or is it getting old with everyone CLAIMING "best battery life" when you usually end up with the same or worse than a stock HTC kernel?
I have tried NetArchy, KingKilck, and a few others only to have my phone die in the same amount of time or even sooner. Why is this? Well what you all don't do is take into account the MANY different variables that affect battery life.
The thing that tanks my battery the fastest is the fact that I work in places with low (10-30%) signal. This kills the battery because it is constantly searching for a signal and talking with the cell tower. I am willing to bet most people that have bad battery life are in low coverage areas. I simply have learned to put my phone into airplane mode and have people text me on Google Voice as I still have a WiFi connection. WiFi uses FAR less power then the cell radio in low signal areas and you can still maintain connections if you have everything setup right.
I am NOT in any way bashing the work and effort that has been put into these kernels but with the latest HTC kernels having unlocked FPS and great battery life why would I want to even mess with a custom kernel? The only reason I could see is for overclocking. I wouldn't even run one for underclocking as I have found this to NOT be an effective way to prolong battery.
Just thought this needed to be said. What I have said here also applies to collin_ph tweak. There have been many reports of the "tweak" killing the battery even faster and I have verified this.
Mostly true, but I think it really depend on what rom, and kernel you are using, plus your signal strengh.
I've flashed very often since the day I got the phone to get maximum battery life out of it, and netarchy's usually worked for me.
I've also tried stock/default that came with Myns 2.2, and best combination that worked for me are Myn's 2.2 and Netarchy's 4.2 cfs havs smartass more agressive kernel.
there are too many kernels out there and you just have to find a working combo that works for YOU at the end of the day buddy.
Oh and I totally agree with you on this thread that it does get annoying/frustrating to see these threads, and you decide to go with it, and it turns out to be a crap.
I've tried a lot of things and never really gotten better battery life than stock, but I have gotten about the same with better performance, which is good enough for me.
The only thing that really improved battery life for me was butchering the phone - turning off background data and auto-sync and using JuiceDefender (disable mobile data when the screen is off, turn it on for 1 minute every 15 mins). But I decided I prefer using my smartphone as a smartphone.
I've come to accept it. My average battery life on weekdays is 8-10 hours. I wish it were 12-14, but I can live with it. When I stay at home on weekends, where I have Wifi and good cell signal strength, I generally get 20-30 hours with moderate use.
I live with plugging my phone in at work, and I got some of tuttoit's cheap batteries off eBay. It works well enough for me.
Anytime you flash a custom kernel you have to give your cpu time to adjust to the new stuff included (havs,bfs,cfs,voltage...etc..)your battery life gets better days after using these new kernels not immediately after flashing...
i have flashed myn's 2.2 and using setcpu to underclock when in black out mode and using titanium backup to "freeze" apps that somehow start themselves. my batt life has gotten way better than what it was on stock os and settings. ive also tried to do the *#*#4636#*#* and cant get into testing mode to change from gsm to cdma but im willing to bet its on cdma anyway.

You can use Roam Control to force roaming in those areas, if they have good signal strength with another carrier.
It's the same power usage as in good signal strength Sprint areas.
im still trying to find the reason for my battery drain, i get an ok battery life with heavy use, but even at idle it varies, the other day battery stated 80% all day long, i ran it down as best as i could and got it to read 10% at 4:30 in the morning, i set it to charge, wake up, unplug it, go back to sleep, wake up only a few hours later to see that my battery reads 60%, im sure that nothing out of the ordinary was running, i cant seem to figure it out, and i have done 3 hard resets to try and find out whats draining the battery, seeing how it varies and is seemingly random at times, im starting to think it may be the radio
I would highly suggest buying a extended battery. I have complained about the battery since day one. Got the extended battery at sprint for $54. I went 8 full hours.. I mean 8 FULL hours hard usage. I turned the screen off 3 times. Wanted to see how the life would be since I used to be on my for for aboutt 3 hours and it die.. today tturned on phone at 9. Its almost two.. 93%.. I did have my brightness all the way up yesterday and overclocked at 113 on interactive.. tomorrow ill turn everything on and run it hard again.. ill turn my airwave off also. I will get worse reception than u would at work.. -115 to -120.. I hit -125 already but I heard -120 is no service..

Sorry but I like my evo to stay thin. X)
Same here.. but the extra thickness isn't really much a bother to me as much as charging and carrying 2 extra batteries. 6 hours now and at 75%.. I love it.. and glad I got it. Just hope when I get a different phone I can use my extending for it. Like I had tp2 and same batteries as the evo..

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

I'm using Helly Bean and my battery life with my low use habits has been incredible (30+hrs). However, in areas where I don't get signal my battery plummets. Unfortunately, this includes my lecture hall, where I am for several hours a day.
I'm using the K47 baseband. I understand that there are other options. Do any of them stand out for handling low signal situations better? Alternatively, is there a software solution?

You can try putting your phone into airplane mode for some of that time
Or test the various modems out there and determine which is best for your area ^^
The one thing that jumps out at me is WiFi, either turn it off if not in use or you can at least make it auto turn off when sleeping. Do this by going to settings>WiFi>hit menu >advanced and change WiFi when sleeping to never.
You can also turn off data but airplane mode should take care off all of it.

Use juice defender. It cuts data while your phone is asleep and automatically turns it on when you wake it. I work in a cooler and spend hours there and in a basement of a casino in vegas, my signal hours out constantly and juice defender doubled battery life for me.
