I'm connnected to 4g right now (don't have it in my area officially) and in the short time I've been connected it went from 65% to 59% in MINUTES! DO NOT WANT! FAIL!
 
It seems to me as if my phone can last two days of light to medium use as long as I'm using WiFi for data instead of 3g. The minute I leave the house and hop on 3g my battery drains at an amazing speed but if istay home or anywhere else using wifi only, my battery lasts a long long time.

Thanks very much, that's good to know. Although I wonder if the constant on/off of 3G is worse for the battery than just leaving it on...

At any rate, when you turn off "Mobile Network" altogether, is it correct to say that none of these settings matter, because 3G will just be off completely? I'll be out of town this Saturday and want to turn off 3G to see how well my battery does all day, since I won't have 3G access anyway. But I don't want it to still secretly be running in the background!

Turning off ALways on Data has a significant impact on my battery for the better. I have tested this out pretty extensively and leaving it off is definitely the way to go. Also a great addition to my apps has been Y5 Battery Saver. It is in the Market and what it does is this: Every time you connect to WiFi it records your cell location. You leave your WiFi on and it disables it... then whenever you are in the cell location of a known WiFi spot it turns your WiFi on automatically. When you leave that location it automatically disables your WiFi again. It has worked great for me and has saved me because I always forget to turn WiFi off so it just sits and looks for WiFi while I am out and about draining my battery in the process.
 
After using the Samsung Galaxy S phone for about two weeks, constantly averaging one full day's use out of each full charge, my phone is suddenly lasting much longer! I have used it occasionally now for 26 hours and still have 73% remaining! This phone will definitely last two days easily, unless you use 3G heavily. ^^ I like this phone!
 
Just bought one of the 1800 mAh batteries from Ebay and after initial wall charge I installed it in my Evo last night. Currently 7 bars are still showing or 70% charge left. Usage today a few checked emails and about 4 or 5 calls.

Hi I have been reading this forum for sometime now and I just wanted to give my input on how my battery has been doing and to find out if this is normal. For me I have noticed that the battery will hold onto a charge that is with doing all the battery tricks I have read up on (which is good), so from the time I unplug my phone its at 100% and leave for work it will drop two percent I leave for work at 2 and get to work at 3pm but that's with making one call. By the time I get to work I will usually get a text which will take it down to 96%,make a few calls and send some more text throughout the night but what I have noticed is that when I receive a text and send it back it will drop a % every time so buy like 6pm its at 93% so making a call does not pull a lot of battery power it seems like sending and receiving a text will take a little more power then making a call but then I have found out that 93% will not stay that way until I go to use it again it seems to bottom out at 91% so its like even though it has stopped doing what ever I was doing the battery still has to cool down and bottom off. Here is were I notice a really big drop when ever I get on the internet it will take a % or two to load the page and just scrolling up or down it will drop another % so my 91 is now 87% and this will happen for as long as I am on the internet it just eats up the battery so I don't stay on it to much but then it has to bottom out so 87 turns into 85. I then send a few more text and just playing with it or showing it to somebody will take it to 78% and buy that time it’s almost time for me to go home I leave at 10. By the time I get home its at 73% so for me this is a normal day at work and most often when I get home its no less then 70. I just wanted to no if this is normal battery drain because I was heaving a problem with my phone and I took it into a sprint repair store and they were going to replace it told me that the battery failed the test but I did not want another phone because of course it would have been a refurbished phone and I don't want somebody else’s headache so I asked them if I could just get another battery which they then gave me so I have been testing them both out and have not noticed any difference between the two of them. Please tell me that this is normal so I can feel better and not have to deal with a refurbish phone.
OH AND BY THE WAY EVO ROCKS
 
Ok it may just be me but, after the update my battery charges quicker.
For the past 2 days I noticed after normal use I get home at about 8 and put the phone on the charger and the battery light turns green after 3 hours of charging.
Yes the battery was discharged, although not complete but at about 10%.
Usually A charge take longer overnight.

It's a stock battery, Anyone else having this experience?

It shouldn't take more than three hours from your wall charger. I can go from 10% to fully charged in less than two hours.
 
I haven't noticed a difference. Do agree though that wall charger charges really fast. I was just at 50% and it fully charged, while I was using it, within an hour or so.
 
With Always on Data unchecked, my emails don't push through. Do texts push through if this its turned off? I haven't wanted to test that out. I guess I can always go in and manually refresh/update my Gmails, that is what I do with news, Facebook, etc. I really only care about real time Gmail, texts, weather and..... that's about it I guess.
 
it takes less than 2 hours to charge my phone if its really down low. Download battery indicator pro, it tells your about how long its take to charge your phone by AC or USB. but for me, since the update, i no longer experience the 10% battery drop within the 15 mins after the unplug =)

Yes, texts will still work because they are not considered data, they are considered a class by themselves, i.e. "texts." :)

But having Gmail set to auto-sync shouldn't be a big battery issue. That's the only thing I have set to sync (actually, I just started having weather sync every hour too) and I haven't noticed any drop in battery performance.

Likewise... there is (or was) a app in the market called "Network" that got you to the necessary screen, it appears to be gone now.

Side Note: Can anyone comment on my question (with the link) at the top of this page? Really want to see if that worked for anyone.
 
I took my phone off the charger at about 12pm ish, didn't have anything on. Got to my friends place did some wifi. by 5pm I had 50% and then when I left their place at 10pm. I had about 44%. Color me happy.

After 5 hours it dropped 50%, and then after another 5 hours it dropped 6%? How does that make any sense? What does "did some wifi" mean, exactly?
 
I dunno. I was shocked. I was using the wifis.. I was using my friend's internet rather than Sprints network for browsing the net.
 
More importantly what are your settings looking like? Do you have stuff auto syncing during the day and what are there frequencies? Did you do any batter tweaking?

I took my phone off the charger around 8am this morning, by 12:30 it was already down to 49%, But I was on wifi for about 2 hrs and streaming pandora for close to 45mins, I always was doing some heavy browsing in the morning. I still don't feel right about it depleting that quick tho by 12:30
 
I took it off the charger, had everything obvious off that could drain the battery, went to the gym, and never used it. Then I got to my friend's house connected to his Wifi, went to the android market place once or twice, turned off background data refresh, checked my email or whatever in the middle of games, and texting. That's about it.

That makes more sense. Because I've been seeing people claiming 31 hours of battery life. I really dont think on the Evo you can have background data/auto sync enabled and get that kind of battery life. I turn off the mobile network sometimes when im driving but i cant see myself disabling those features which I use quite oftenly.
