Is 3g signal the same signal if I turned it off and just had 2g? Why I'm asking is I usually have 0-1 bar at home and I know poor signal strength causes battery drain. If I go 2g will I have more bars or the as I would in 3g?
I'm asking this because I have been told when I bought my last phone.. tp2 that it had to have a data plan or nothing will work. So my question is and have asked before but never have gotten a response is.. if I turn data off.. will I still get incoming sms? Im I better off getting juice defender then? Will this help? That is.. is sms workable with data off.

SMS is 1X. You don't need data for SMS texts. Texting is available on even the OLDEST non data phones.
Now, if you turn off data, you've pretty much eliminated most of what makes a "smart phone" smart.
Spare batteries are cheap, as are several different chargers. One for car, one for office, one for home, one for travel, etc.
Better you get into the habit of whenever you're near a power plug, to plug it in and let it charge. Once it becomes an ingrained habit, you'll not worry about battery life as much and you'll get much more enjoyment and use out of your phone. Besides, better get used to it. Processor speeds, power hungry hardware keeps advancing, battery tech doesn't.
I have 3 batteries and a tp2 I use to charge the others while not in use so always have a full battery. I don't sync anything but my email. I can always turn the data back on for internet or anything I'm using for internet. Why I mentioned juicedefender... also I underclock and undervolt. Just looking for a longer battery life. I don't get more than 4 with moderate use.
Edit: one doesn't have to get use to it if there are ways for longer battery life. I'm sure you have all the accounts sync and checked, screen brightness set all the way up, 4g on, gps on, and overclocked and saying get use to it its a smart phone.
I don't have 4g and I do use the internet a lot and check my email. I get my email to sync when I chose to look at my email and don't need to check every so often wasting my battery. Not everyone uses all the stuff you can use the phone for or as much as someone else.

You're saying you only get 4 hours life?????
I keep wifi on, BT on, data on.
Between 8am and noon, I've browsed, made 2- 30 min phone calls, updated 3 apps from the market, played (shhh, don't tell my boss) 3 different games for at least 15 mins each, checked the local news. and I'm at 82% using the stock battery.
Also, have exchange push enabled, gmail pull at it's quickest interval, NOT overclocked, not running any task killers. No 4G here, so that's off and GPS and NETWORK location are also both off.
If you're down in 4 hours, you have a different issue. Better install a few monitoring programs to see what the heck is going on.
Granted the 1500mah battery is way too anemic for this phone, you should be able to do better than 4 hours.
I agree you defiantly have something going on causing a battery drain. I used to get 6-8 hours with moderate use and have worked a lot of different things to finally get up to 14016 which i am happy with (i still dont see how anyone gest 30-50 unless there "moderate use" is not touching the phone except to have 1-2 calls or something on the break.
i recommend the paid version of system monitor. it lets you see your battery drain cpu usage and device usage. it also has a history option that will let you see which apps use the most power. The only other thing i can think of is you have an app preventing the phone from sleeping so that your setCPU profile and juicedefender are not doing anything most of the time.
as far as turning data off. You can receive SMS, you receive phone calls obviously, you can not download MMS or anything else requiring internet data. there is nothing wrong with turning it off when nothing use. (i personally use ultimate juice so that unless i have my screen on and unlocked or my phone is on the charger data is off.

Mind sharing your exact setup? Rom/kernel etc. Seems like your getting pretty good mileage.
I leave my phone on Wifi all day at home (no signal either, 1-2 bars) and battery drain is minimal now and it's not constantly looking for a data signal. I go approximately 30+ hours on 1 charge
I have the system paid app already. My problem is I have the worst reception where I live. Usually –105 to -118 and -120 I heard is no reception at all. So its more tower pulling and increasing voltage to get a reception. So I'm trying to do what I can to save a little battery...

Rooted stock, deodexed. Netarchy kernel. Have old airave at home for voice, and at home, I use WIFI. GPS doesn't seem to have that big of a drain
I was slightly incorrect, I do have setcpu profiles. Thought I had them off, but they are on, but NOT overclocked. For battery >75, or on power, default max, 384 min, conservative. Screen off, 384/384. Brightness is NOT high as I work in a well lighted workspace. Sometimes I do turn off WIFI tho. It'll fight with bt on occasion. Same freq. But usually it stays on. I do use phoneweaver for profiles. And I also use TASKER to create specific app profiles. IE turn on gps, wait 15 secs, start gps capable app, turn off when app closes, etc.
I also did the battery calibration "trick" and every now and then I clear the battery data from recovery. Not sure if that helps/matters or not.
I don't use the camera app, nor do I use friendstream. GTALK (known battery killer) is set to NOT running/syncing.
Is it great battery life? no, I'd say average. About what I'd expect. I'm not expecting 24 hours with it while using it and not recharging. When I'm out and about, I'll plug it in any chance I get, and also have spare battery or 3 from my TP2. For a full charge, I have an external battery charger. I was using the TP2 as a charger but don't trust it's charging circuits either (yet another HTC product. lol)
I just checked and I'm at 49% assuming the "battery guage" is accurate. 8 hrs to 49%. Few texts, another call, some more news, using TIKL. Time to plug it in and let it charge. But it was a nice test to see how long my normal use would last.
If your signal is that low (to the OP), try to get an airave, esp one of the newer ones with 3G/EV capability! I am going to call and ask if they'll replace my older one with the newer one.
I already thought of that option. Don't have internet here... downfall..

Today was my first day at work since i got my Desire on Sat. So it was the day without regular charging.
Firstly, reception was poor as compared to what i was getting with Touch Pro 2. Same network (Orange), same place, less signal bars and less 3G coverage.
Secondly, unplugged phone 7 o'clock this morning, 100% charged. All day only had time for couple of calls (10-15mins). Used internet (3G when available) for max 20-30mins. Tried couple of games for 15-20 mins and at 7 o'clock at night, the battery was 15%. This is not a heavy use by my standards. Used to do a lot more on Touch Pro2 and battery used to last 2-3days. (I know the capaciy difference btw Desire and TP2 battery but still, Desire should last atleat > 24hours)
Not sure if all these issues are related to Orange ROM/Radio. Will we (on Orange) get OTA firmware update like T-mobile, which has apparently improved their battery life? If not then ...... :-(. Not satisfied with the battery life. Shame it is such a good phone but battery life and signal strength is putting me off.
Whats the fun if you have a "superphone" in your pocket but cannot use it to its full potential due to these two isuues.
Mine was the same,
But after a weeks worth of usage, its now reasonable, IE 18 hours between charges,
Fon22
I totally agree, there are other posts telling us to turn off or reduce all sorts of settings, its ridiculous that you would have to run any phone at less than its full potential just to compensate for a poor battery.
Sure you could buy a second battery but if that was necessary then they should put two in the box
If you leave gps on then you are asking for trouble, a lesser extent wifi. Having a toggle on off isn't such a hardship though. Poor signal hammers the battery too.
I easily last the working day (7-7) with an hour of music and 2 hours surfing and a smattering of calls and texts.

Come on guys, if you have a laptop, and you turn on bluetooth, wi-fi, play some games etc, it WILL run the battery down faster. It's just common sense. Just because this phone does heaps of things, dosn't mean it will last forever. As phones get more features, they are getting worse battery life - in general. And android is a data centric device, I would get used to it, or simply turn off some synching features if you need to get through more than half a day. Or perhaps get a spare battery etc.
Just out of curiosity did you have your previous phone to constantly sync throughout the day for time, email, google account, marketplace updates, location, weather using gps, 3g, hsdpa, accelerometer etc? Remember some of these connect are activated every 5 mins or so. Will make it worse if you have poor reception. COMMON SENSE PPL!
My issue is that even after the T-Mobile update, last night I charged phone on this time and it would only get to 98% again. Then drop down quickly.
If I charge it off, It seems to be ok (although I will test this again.)
Frustrating.
My battery life is woeful (TMo uk, updated firmware). I've been trying to figure it out using Juice Plotter to record power usage. Basically, whatever I'm doing, if it's on the battery falls off a cliff - I'd say 10% per 30m and my first impression is that it makes little difference whether networking is enabled or not. This makes little sense to me, I've always found in the past that 3G is just about the most power intensive activity on the smartphone, but it's consistent with some experiences I had flashing roms on my Blackstone - some of them would just run the battery down, others would go for ages. One hypothesis is that when a phone is in that kind of "sick" power state, the drain is not really related to which facilities you're using, but something deeper - perhaps the CPU is running full throttle all the time, or something else. I have no idea what's going on right now but I know I have an unusable phone which lasts half the time my Blackstone did with heavier use. I think many others have the same problem and I wonder if there's a bad batch. Bad news if so as we'd have trouble proving it and getting exchanges.
My next step I think will be to hard reset and run it in a very basic mode for a while, maybe some of the apps are causing it.
I'm also finding out that battery life improves dramatically after the 5th 6th charge. When I first got my Desire I could barely make it through the day, after properly charging and letting it discharge all the way to 10-15% now I get 18-20h of battery life with wi-fi on non stop (but with the setting to to turn itself off after 15mins of inactivity).
I was very worried about this when I first got the phone, but now it's starting to be better and better at battery life. I know my demands from a smartphone when I buy it and if a phone get's me through the day I'm OK with that, plus I have chargers at home, in my car, at work, so it's not a problem
I've got one of the very first batch of T-mobile Desires that were shipped on 26th March. It has been updated with the T-mobile 1.15.110.11 patch.
I last charged it on Saturday afternoon. I've only had to start charging it again this morning Tuesday. I've been making a few calls, probably 10-15 minutes total. A few texts. Browsing with G and 3G, maybe a few of hours worth in total. Little bit of Bluetoothing, though that's only a couple of minutes worth. I've had it down the pub a few hours where the T-mobile signal isn't brilliant, so it will have been doing a little "shouting" to find and communicate with the nearest T-mobile mast.
But that means it's lasted a good 66 hours admittedly with fairly moderate use. GPS, Wifi and Bluetooth are turned off unless needed. And it's not regularly Syncing with Facebook, Twitter and all that stuff. The only regular syncing is the weather.
Not sure if these are bugs with some hardware/software or standard functionality with your usages. I'm getting excellent battery life with my usage patterns/settings and far happier with this than with any of my previous devices, since this adds an exorbitant amount of power-draining functionality and flexibility over them too.
- Heaviest use is netting 28-33 hours.
- Typical use is getting minimum 3-3.5 days.
- Light use (also the norm for me me) lasted 5.5-6 days.
- Basic inconsistent call/message/email/net/stocks/news/stop watch/GPS/ compass/notepad/office/weather/ vid/pic/audio throughout the day kept the battery at 84% after 24 hours. 3G off, using WiFi. I don't keep any but the needy apps/settings running BTW.
- Charges to 100% always and stays up there consistently as expected.
However there is a pertinent aspect yet unmentioned;
Biggest difference between my usage and the typical internet crowd is that I don't use or bother with "social networking" (Facebook, MySpace, Twitter, etc) or its likes nor do I play any games on this (hence sync with such apps is off and any updates are set to manual). However rss feeds, e-mail and IMs with close ones I do use during the day when I have spare minutes.

Same situation as mine there.
Sent from my HTC Desire using the XDA mobile application powered by Tapatalk
I'm deffo leaning now that there are faulty batteries out there causing the problem. I can get good life if I can get the battery to charge properly. but when it doesn't battery lasts hardly half a day. I don't use any apps that require automatic updates (all manual or off). But net on drains it very quickly (if I leave data on). Faulty Batteries I feel.
My Desire has a better ability to hang on to a weak signal than my other phones. I am on T-mobile. Battery life is adeqaute, in that, I can get through a day of use before a charge is needed. Will switch-off GPS and see what happens -I never had GPS on all the time on my other Smartphones.
Coming from a G1 that could barely make it through the day on standby this phone seems pretty good.
I got mine last friday it has just come off of it's third charge. I charged it for 3 hours when I got it, ran it right down >10% then left to charge up fully again.
I installed JuiceDefender and bought the UltimateJuice upgrade as soon as I got the phone.
Day 2 (with JuiceDefender) - battery lasted 13h27m, thats with WiFi, phone calls, MMS, 3g, internet browsing/showing it off to mates in the pub and then listening to an album on spotify in the car.
Considering this is a new battery and it still needs several charges before it is working at full capacity, I think that is pretty good for a smart phone! It can only get better, right?
JuiceDefender - I can't recommend this app enough, I don't want to mess about with Task Killers (that don't really save battery), I don't want to stop stuff syncing (because thats the whole point of this phone) but I want to optimize my battery life to get me through the day and this app does it so well!
I've currently got it setup to turn 2g/3g off when in standby but set to turn data back on every 5mins for 30s to allow apps to sync. You can specify a longer interval which will obviously save more battery over the course of a day. The phone connects back to a 2/3g connection so quick when you bring it out of standby so your not waiting around to get back online.
Switch on WiFi at known locations - I have this setup because at home, 3g signal is a bit patchy and it probably uses more battery constantly trying to get a 3g signal all the time, than it does if it is just connected to WiFi.
Turn data off between 2am-8am while I am sleeping.
Turn data off when battery is below 15% - with my G1 it would hit 15% just as I'd be heading home on the train in the evening, so I'd turn data off just so I could send a few texts or so I had just enough battery to make a call. So I figured I might as well use that last 15% battery for basic phone operation and give me enough battery to get home! I probably don't need this with the Desire though.
Any one else using JuiceDefender?

WOW, can I have your battery please ...
What did u do to get this powerhouse. Was it weaker in the begining and got better with charges or was it like this from the begining?
I dont use GPS at all. Only for navigation, when in car and then it is on charge. Normal day.. no gps, no auto data connection - do it manually when internet connecttion is neede. But battery doesn't last a day, merely 12-14 hours. Charged 3 times yet, only 3 days old Desire.
I cant find juice defender in the market?
When I first got my Hero I remember my battery life being terrible, most of it was down to fiddling all the time, however over time my usage changed and the battery had been charged a lot the life was a lot better. Also there were a number of radio upgrades installed, which probably helped.
Since I've got my Desire, the "desire" to fiddle hasn't stopped and I feel as if I'm in the same situation as I was with the Hero.
My opinion is that over time the battery life will be better, as with the Hero.

Yes both Ultimate Juice and Juice Defender are in the Market.
Juice defender was missing for me a couple of hours ago. But actually, when I installed it thinkgs started to go wrong for me. May be a coincidence, or may be a conflict with some other sw.
Following shocking power drain, I have hard reset, and left it with nothing syncing and all networking disabled. As you'd expect, battery level is barely falling in standby. Now to start adding things back in and see what efects it has. First step is to spend 30 mins browsing over 3g, previously this would take out 10% of my battery.

It's not there for me either currently, neither is mybackup pro... :/
Friend has a new Desire Z (bell, unlocked). Using it on AT&T network.
When at a house, and we use WiFI (30Mbps DL, 25Mbps UL), the speeds are VERY inconsistent. With my iPhone 4 using speedtest.net, it shows up as 20/15 each time. (WiFi is a little slower than the modem).
With the Desire Z, we get 15/10 (which is fine/acceptable). Then 3 minutes later we do it, we get 5/2. Without even moving the phone or touching the modem connection (not downloading anything on the computer), the connection just gets slower. Then it might be fast or slow, basically it's a toss-up.
The first time we noticed the issue is because when we are outside, we get HSPA speeds of 2.5/1.0, then randomly decreases to 0.1/0.05. HUGE difference. And VERY inconsistent. He is using a microSIM from iPhone 4, with an adapter, so we figured maybe the SIM card is getting loose at certain points? However, the WiFi is also inconsistent in addition to the HSPA, so it's probably not that.
What should I do? Is this the situation where I have to flash a new radio or something? (Please suggest others if I am wrong).
Thanks!

Also, his battery is kinda weak. The battery health is apparently clean/healthy. He came from an iPhone 4, where he would have 3G, WiFi, and GPS on at night but not actually using them. Wake up, and 3% battery loss, maybe 5. WITHOUT using them, just having them on.
Now, with the Desire Z, we have the WiFi + 3G on, but NOT the GPS. He is losing 20%-25% in 8 hours without even using the phone.
Information about battery shows a high Cell standby (25%) and Phone idle (25%) percentage. When going into Spare Parts > Partial Wake usage, we didn't find anything really fishy. BUT we had rebooted so perhaps some info may have been lossed. Should he just go to sleep tonight and report the Partial Wake Usage statistics again?
We have a feeling it may be some apps refreshing at night.. But he clears all the apps with Advanced Task Manager except for like Facebook (2 hour interval refresh), GMail, and Google Voice.
I highly doubt a 20% battery decrease overnight is normal.. My mom's Atrix only loses about 5% overnight, with the same parameters I gave before.
I thought it may be a bad battery, BUT the phone idle + cell standby are abnormally high.
Thanks!
Does anyone have an answer? I was wondering this
I have been running CM 6 since November and just recently flashed CM 7. On both ROMs, Cell Standby and Phone Idle have been very high on my list of things that are 'draining' the battery.
For example, today Cell Standby shows as 37% and Phone Idle as 30% for me.
In fact, its very rare that these two things aren't at the top of the list of things that are using the battery for me.... I've seen cell standby as high as 47% before.
I can't speak for the drainage overnight. Definitely doesn't sound normal to me, but my phone is usually on the charger overnight (have enough trouble making it through the day with the stock battery).
Have you tried using Watchdog to monitor CPU usage of apps that run in the background? You could set the notification threshold very low and see what it spits out... Good luck!
gbarayah, thanks for the post, that was helpful.
If anyone can help with the inconsistent data speeds, that'd be very helpful.
And any additional info on the battery would be great too. I recently calibrated it, and will post any additional stats.
Damn it, I forgot to try Watchdog. However, I re-calibrated the battery, let it die, charged it up, let it die, charged it up. I followed the instructions to the letter and all that.
It was at 100% when I went to sleep. Woke up 8 hours later, 74%.
Settings > Battery shows nothing high 40% for cell standby and phone idle. Everything else (Facebook, etc.) REALLY low.
Then I went to Spare Parts > Battery Usage, Partial wake usage, everything incredibly low as well..
I will try Watchdog, but could it just be a bad battery? Or maybe should I try a different ROM?
Thanks!
Not sure if 26% drain over 8 hours is normal or not... Maybe someone else can shed some light on that. My phone is usually on the charger overnight.
The only other thing I can think of that would drain the battery is if you have a bad/weak cell signal in your area. I've experienced that with some job sites where my cell signal is very bad and my battery suffers excessive drain from trying to get a better signal or connect to 3G coming from Edge.
On my week old desire Z running virtuous unity sense3.0 rom and streamlined kernal i very rarely see phone idle and radio burning battery lik you say. Radio occasionaly gets high but only wen in bad coverage areas other than thats its ok.
Battery is still rubbish though due to fact even on 2nd lowest brightness setting screen seems to burn 80%-90% battery
Just checked: phone idle:2%
Cell stanby:8%
Screen (lowest setting):70%
Not this isnt a great example as its taken over a short period of havy use but it still reflects the relative proportion of the battery draining elements in question.
Also a question, if you have a live wallpaper set where is its battery drain shown? Screen, or launcher?
Not sure what to say about the high variable speeds.
Sticking to just GSM(2G) rather than AUTO will in some cases increase the signal and battery life at the expense of slower connection speeds. As mentioned when the phone struggles to get signal the battery gets drained alot faster.
Lower the refresh intervals of all the apps to the maximum period of time or a reasonable amount like 12 hours for FB for Sense, HTC Sense and Weather and 4 hours or Never (to make it on-demand) for Facebook.
Setting the Wi-fi sleep policy to "Never when connected" may make it on-demand too - when an app needs to update Wi-fi gets turned on again
If they have "Use wireless networks" checked to allow the clock-weathers mini-widget to update then they should try removing said clock and re-adding it, but search for the city when doing so. It'll provide them with a general outlook for their entire city and not force it to download and update the information for wherever they are whilst out and about. E.g if you were in London and went from Westminster to Peckham, it may update as you pass through each borough.
Live wallpapers and masses of widgets that need to constantly update are nice and everything but they can also drain the battery.
Think of these suggestions as ways to cycle the battery as well as save it.
I can't think of anything else to add.
I'm using Cyanogenmod 7 and it's pretty damn good. What do you think is the best ROM with Gingerbread if it's more lightweight and easier on the battery? (I honestly don't think the ROM accounts for the 25% battery loss but we'll see)
MIUI or mexiDroid for me?
By the way, could it just be a bad battery? I was thinking about picking one of these up:
http://forum.xda-developers.com/showthread.php?t=940263
$8 and people said it's okay.. What do you think?
Thanks, and I JUST calibrated recently, so once again I will leave phone off overnight and report.
-----------------------
As for the network issues, I FIGURED IT OUT!!!
I believe it was the Speedtest app itself that was messed up. Like I said earlier, I don't have live wallpapers (just info) on, and also NO GPS unless using Navigation.
Well, Speedtest was connecting to WICHITA, KANSAS. I AM IN NEW JERSEY. WTH??!!
Anyway, so I'm going to keep GPS (satellites) on, it connects to NJ, and Voila, GREAT SPEEDS!
HSPA about 3.5/1.0 DL/UL
HOORAY! Network problem fixed!!!
Only issue is battery still D:
Honestly, I think it may be a bad battery. Partial wake usage doesn't show any app going nuts.. Every refresh interval is like 4 hours. And I use Advanced Task Killer to kill all apps before going to bed. I downloaded "Watchdog," let's see

well... can't be that odd. Mine are
cell standby: 8%
Phone idle 6%
display 51% (highest)
dialer 11%
wifi 10%

about conn. speed. I haven't used speedtest yet but downloading speed on the phone is slower than on PC remarkably using the same internet connection

WiFi will always be slower than wired connection, probably about 50% if not more.
Also, what setting do you have your display on and how much would you say you use your phone/have the screen on and how often do you talk (hrs/day)

I have auto brightness but I stay in office and not turn it on much (have to work though ) so the display isn't on much (when i said HIGHEST, it means highest in the list )
I have to phone connected to wifi all day but rarely use it
Mainly use the phone to text and talk less and 1/hr/day
Just try left the phone unused (stand by - airplane mode) for one day, drop about 20% or so
Its seems like its getting a little better.. only lost 10% overnight. Guess its calibrating

Maybe I'm just used to how my previous 2 phones functioned. I'm used to having WiFi enabled 100% of the time, while still maintaining stellar battery life. Unfortunately I'm not able to do that on this phone. If I have WiFi enabled, and it doesn't matter if it's connected to a network or not, and it also doesn't matter if I disable "Notify when open network is available", I get really crappy battery life. I've attached 2 pictures that show exactly what I'm talking about. The picture with WiFi disabled is what I get from letting my phone sit asleep for an hour or so. Battery life doesn't even move. It stays at 99%. NORMAL! SAME EXACT THING, but with WiFi enabled and my battery drops to 95%! Checkout the "screen on"... the screen was off pretty much the whole time yet the battery went down to 95%. This is really bad! This has happened to me using a stock, non-rooted device, and it also happens when I used ViperROM and Calkulin's ROM (spelling?). Also check out the abnormal "awake time" activity when WiFi is enabled. Maybe this has something to do with it?
Anyone know if there's a way to fix this? I can't be the only person experiencing this problems -_-
Wifi ate my old Hero CDMA battery too. Having the extra radio turned is bound to use more battery.
I never pay that much attention to it. I just leave it on when im at a known wifi and turn it off when i leave, no sense in having it search for an ap if I'm not near one I want to use. I also have my phone set to us 2g until I want stream or browse. I make 5 to 10 calls a day, occasionally look stuff up on the to net, have my mail pushed and call it good when 14 hours later I have 23% left. I don't care what uses up the battery as long as I can make through the day.
the battery drop at that high don't seem like a good way to measure anyway. From 100 to about 95% dips extremely fast on my phone.

Mine has been terrible for awhile. Even Odin back to stock and it wasn't any better. Now I'm on a clean flash with very little installed and I've only seen minimal improvement.
Here are a couple of screenshots from this morning looking at while I was sleeping. Lost 25% overnight. Had an hour of awake time with near zero screen time, seems like a lot of battery lost
You're letting way too many apps sync in the background, your phone is not reaching deep sleep. I bet you left your Google account on auto sync. Your email is syncing too often. don't leave wifi on overnight. You're getting poor signal too.

25% loss is not bad at all. I've had 68% loss complain about that lol

I've always let my Google account sync and left wifi on at night. It just seems like the last month or so it's chewed up lots of battery. Heck with my old desire it'd only use 3-4% (with basically the same setup) overnight.
I had this problem and was able to fix it by repeatedly throwing my battery on the sidewalk. It helps to re-excite the electrons in the battery and improve battery life.
I am trolling, in all seriousness, lithium ion batteries significantly reduce in capacity over time. It is perfectly normal for the battery to last 25 to 50 percent less long just a year in. Pro-tip, you can find replacement stock batteries on Amazon for about $10, just make sure it is an OEM battery. If you are nice to the tech or store manager at your local sprint corporate store, sometimes they will give you a replacement battery for free.

Thanks. I'm with us cellular and the phone is only two months old. They do have a battery swap benefit, but I think it can a crap shoot on the quality you get back.
I un installed that hacked s-voice app, that seemed to help quite a bit.
So it must be something with wifi. Had wifi off all day yesterday at home and last night (just using 3g connection) and I only lost 2% overnight. On 16 hours with an hour of screen time and still at 79%. Not seeing the wake ups and wakelocks like I was before.
Also if you remove your battery. Try to spin it with it laying flat. If it spins replace the battery. Bloated batteries do not hold a charge. I w

Sounds like you've got apps set to sync when on Wifi only then. To confirm, try leaving Wifi on but turning off background data. If your battery life improves, it's definitely an app. Then you just have to go through your apps and figure out which one it is.
Gmail can be set to push so you don't have to worry about it syncing unless necessary. But if you get a ton of emails, it's still going to hurt.
Also, I disagree with revamper, if you get poor signal you should leaving Wifi on as much as possible. Being connected to solid Wifi will drain less battery than your phone constantly polling towers for a better signal (given identical app behavior, which you don't have atm). I'd still turn Wifi off when moving about, as you won't be on a single, solid Wifi connection and you phone will be polling both towers and Wifi networks, resulting in increased battery drain. You also want to set Wifi Sleep Policy to not sleep when the phone screen is off (otherwise as soon as you turn off the screen Wifi is disabled and you're polling towers again). From what you've said, it sounds like this is already set though.
The best thing I've ever done for my battery life was flash Calkulin's ICS ROM. 4 days of standby or a full day of some really heavy use. Email is the only thing that syncs automatically (push). Other apps like Facebook aren't that important to me so they only sync when I open them.

I had a battery cook in the phone this weekend and this is what the sprint tech did. I picked up my phone after being on the charger overnight and it was almost hot enough to burn me. I took it in, they popped it out and spun it like a top... Handed me a new battery within 5 minutes.
Yeah it's probably wifi. I also have much higher idle drain on wifi than 3G right now, although I haven't had time diagnose it. Actually, I hadn't bothered because I was planning to move to an AOSP ROM from stock ICS once kernel source was published, but I'm losing my patience. The AOSP guys seem to have things worked out without source anyways.

I also have extremely high drain while on wifi, I just made it so the wifi shuts off when the screen shuts off
I noticed my battery life is terrible. My phone is only like 5 weeks old. I've tried the battery saver apps, power-saving, and pretty much every other tip. I start off with 100% in the morning with brightness turned down and everything else and I mainly listen to music more than anything so the screen is usually turned off. It still manages to go from 100% at 7:30 to about 17% at about 4:30. And the phone is turned off for about 3 of those hours. Also the other day I started playing TDKRw/100% battery life at 7:30 on high brightness and power saving was off. At 10:00 the battery life was at 15% not to mention I paused the game a lot. Is this normal at all?
Seems ODD. My phone is like that as well but one thing that i noticed is turning off cellphone data. that helps battery life big time. try that and see how it goes.
The TDKR, would be normal, the high end games just gobble up power, often even consuming more power then a charger can keep up with.

Have you read through the thread Woodrube posted today?
Lots of good info that may help you out a bit.

I was like that when I bought my phone, but after playing around with some ROMs and kernels, I found what's working for me - ParanoidAndroid + Ktoonsez kernel = 2 days moderate use and over 5 hours screen time with 100mV undervolt
OP might have bad reception too, that'll eat your battery up
Reception is a killer battery eater.
Especially for me, just moderate texting and some short phone calls will drain my battery.
It's because where I live, the signals are fairly weak and I will get EDGE or 3G data most of the time.
Additionally, check your wakelocks. Sometimes applications run during when the phone is supposed to be asleep. Getting a handy battery measuring app will help.
Also try turning off sync or turning your settings for e-mail, google services, etc. to manual so they won't run when you're not using the device.
Otherwise, the forums probably have dozens of posts with tips on increasing your battery life.
There are many battery threads, true. But as of a day or two ago, you only need one!
Woodrube ported his thread over for us. I highly recommend evrryone take a few min to read it!

For those of you with poor signal and wind up on Edge, turn on wifi if possible. It uses less power than your data connection, plus, by having it on it disables mobile data leaving only the voice connection which is much easier to get a strong signal for. So in every way this could help with battery savings.
Even if you have a great signal, your wifi will still use less power. I always connect to eofi when I'm able and the sleep policy is set to always stay connected. If you set it to disable while asleep it simply will activate mobile data in its place.

Sorry for the slow response. Haven't had time to get on here. Thanks for all the help though. I was mainly scared though because I heard some of the phones had a bug in them to where it drains the battery life like crazy. I think that woodrube thread will help me tremendously.

The only thing about that is, I barely make phone calls or text at all. Like I might text 3 times day and make calls like 3 times a week.
Does anyone have any tips on listening to music. I use PowerAmp and I probably use my phone mostly for music.
