Battery usage during phone call. - HTC Amaze 4G

Not really an Amaze question, more of a general smart phone question.
How much of your battery is being used while your on a phone call? My phone seems to use about 1% per minute if not more. Is this normal? I've used the HD2, sensation, and now the amaze. They all seem to be the same, reguardless of ROM or kernel.
While the phone is asleep, battery life is great. Talk on the phone for 30 minutes and your SOL!

It all depends. If you are on 4G rather than 2G. If you are using a Bluetooth. If you have WiFi on. There are many things that factor into the battery usage while on the phone. I am always on 4G with my Bluetooth on. I kill my battery like it's nothing.

Well, the other user said something about 4g, wifi, etc.. and is partially correct. The biggest factor is signal STRENGTH. I live in Jacksonville, and the 4g here is pretty strong in most areas. With screen off and a weak signal, you might get a little bit worse battery life.. but actively using the data, or voice, while in a weak signal area- that is the noticeable difference.
I talked for several hours last night, and I lost maybe 15% battery. But I'm pretty sure that is because this town has such good signal strength.
One of the build.prop edits is supposed to tell the phone to stop searching for stronger signal once it has a solid signal.. I'm not sure if that is just cell signal, data signal, or both.. but using it seems to make a big difference. I think the change is included in xboarders roms, but I can't be sure because I use my own build.prop.

Thanks for the reply guys. I usually have pretty good service everywhere I go, dont have to venture out of the metro area much. Always the same results.
Doesnt matter about the wifi/signal/bluetooth it seems for me. Of course 1%/minute may have been a bit of an exaggeration.
But I cant even imagine being on the phone for a couple hours without a few backup batteries!!

talk time on the phone is about 6 hours supposedly, but i suppose they are talking not 4g or 2g talktime, just plain old gsm talk time with no data! 4g is probably closer to about 3 or 4 hours, I ran out of batteries (from 100 percent) after about 4 hours 20 minutes talking to my GF on 4g.

....Which would be approx 1% per 2 minutes.....hmmmm....sounds about right. I just think that is pretty lousy considering we do a million other things with the phone.
Phone calls just arent a priority for us anymore...ha.

I have no idea if you are on stock rom, or if you are rooted, etc.. if you are using one of xboarders roms you should already be using a build.prop like this one, but if not and you ARE rooted.. use a program like root explorer and rename build.prop to build.prop.bak, then copy the attached file(just remove the .zip) to /system
That will hopefully keep your phone from scanning for stronger signal, maybe xboarder or someone else can pop in with a different idea why you would have such issues.
Please check your battery strength- settings>about phone>battery>battery use>then click the part on top where it actually shows how long you've been on battery.. take a screenshot and post it. The more green it is, the better your signal. Yellow is worse to the point it is probably scanning for better signal and it is going to affect your battery.. red would be pretty bad signal(or maybe total loss). This is how you can really know how good your signal is, mine is mostly green or yellowish green. Here is what mine looks like when I'm in the same place all morning, pretty strong signal http://dl.dropbox.com/u/13692699/2012-01-26_11-26-53.jpg

My battery usage is about the same as your is today as far as signal is concerned. A picture right now wouldnt really help, Ive been on wifi calling all this morning and havent used the phone to talk much today.
I am on Forth Bar ROM (which totally rocks!).
I am an Android dummy so thanks for the breakdown on how to install the zip and all. I will post a picture in the next day or so when I have been on the phone longer to show you what I am talking about....

I have heard all kinds of mixed results with wifi calling, ultimately it is only useful if you are in a weak to no signal area, but my experience with it- it would kill my phone 1% per minute if I was using it. My battery life actually got better by removing it from my phone altogether, but others have reported opposite results.
There is a possible easier way to edit the build.prop.. open in on a computer or the phone with a text edit app, go to the end where it says xboarders tweaks, and copy those values into the ones in your stock build.prop, there is an app called absolute system(and a ton of other ones) that has a feature to edit build.prop and will even make a backup of the original..
But if you are on wifi calling, or even have it enabled when you make normal calls, I think that could be why you experience the drain you do when calling..

Ya I hear ya on the wifi calling but at work I really do have horrible signal so wifi helps a lot! And not to mention the call quality on wifi calling, UNREAL!!! I am at a point where even at home where I have great cell signal I still use wifi just bc the quality is so amazing!
But, I actually think I get better battery usage on wifi calling....
Like I said in the OP, this isnt an Amaze, ROM, or kernel rant.....just a rant to rant I guess.

Quite a shock for me too. New to Amaze and pretty much AOSP with beastmod right now to test battery life. Looks fine when asleep but once I start using it the battery drains way faster than my previous 3G or 4G phones, for making calls over 4G data and normal use.
With my moderate use it's hard to get thru the day on one charge. Have to either try a different ROM or find more stuff to freeze / disable!
