I know that battery life has been a hot topic among EVO 4G users. I have seen both sides of the spectrum with some getting an entire day or more out of their phones, while some, like myself, see 5-7 hours at the most. I finally went to my local Sprint Store/Repair Center where I was told that my battery life was "normal" and that EVO users should "except to charge your phone two or three times a day". Then the rep handed me a spare battery at no charge to me and told me to have a nice day.
So, here's the deal. I am a non-rooted, non-anything user. Is the only way to see a 24 hour charge to root my phone and flash a custom ROM? He did mention that Froyo would "increase your battery life a lot". Whenever that's going to happen. Sorry to add another thread on battery life, but I want to make an informed decision, as well as know if this rep was just brushing me off with 5-7 hour being "normal" and then handing me an extra battery for free.
So you got a free battery and all it cost you was having to talk to a fool? Sounds good to me.
I routinely charge every other night with my moderate usage. 5-7 hours would only make sense if I was streaming Pandora all day with 1 bar.
5-7 hrs? are you constantly downloading things? heavy usage? or just on stand-by most of the time? if your using your phone casually, like 3-4 calls ~ 15-20 min each call and have emails coming in at about 2-3/hr and you surf the web about 1hr/day on your phone... 5-7 hrs is not very good... usually you would need to make calls that are 30+ min with heavy browser usage and be in a really ****ty signal area while playing games and texting every 5minutes for you to get such ****ty battery life... there are a lot of forums out there with tips/tricks in improving battery life so don't expect people to start posting them here as there are THOUSANDS of posts on battery life on androidcentral.com and other such sites...
good luck... you should be able to get at least 12hrs on one charge with little to moderate usage -- again google and read for forums out there as there is a TON of information.
I'm curious, are you in a 4G or 3G area? if you have 4G on where there is no 4G, your phone will constantly search for a 4G signal, same with wifi. I find that 3G is pretty fast where I live. 1.2MB down. so I never really turn on 4G or wifi. I've been getting about 14-20 hrs depending on use, but that was only the few times I made it through a day without plugging it in to add music, or try to root it (without success) and stuff. today I unplugged it at 9:40 am, and have been using it pretty heavy. about 15 minutes of streaming video, 45 minutes of music playback, 35 minutes of internet use, constant messaging, some pictures, google talk, fringe running, as well as qik in the background, actually all kind of apps pop up in the background. I am at 50% battery at 5:00 pm. I think that's not bad compared to the N1 I just sold. I will say that I think Advanced Task Killer, from the markets probably helps the battery life. I highly recommend it. make sure you set it up to auto kill apps in the background. I think I get a couple of extra hours this way.

CHARGING EVO BATTERY FOR MAXIMUM LIFE:
You can charge your battery the following way to see if that helps improve the battery life on your device.
1.Connect the phone to the charger and charge the device until the LED turned green with the phone powered ON
2.Disconnect the phone, and power it OFF.
3.Reconnect the phone to the charger, and charge the device until the LED turns green again.
4.Disconnect the phone, power it ON and then power it OFF.
5.Reconnect the phone to the charger and charge until the LED turns green again.
6.Power ON and use.
My battery appears to have the same issue as well. My backlight is at 8%, auto sync is disabled for all services, always on mobile data is disabled, my network is set to CDMA, I'm not overclocked at all. I've done all the other battery saving tricks and I've done all the battery charging tricks.
I played Raging Thunder 2 for less than half an hour this afternoon, and my battery dropped down to 58%. I'm aware that games are pretty intensive, but isn't this a bit much?

Holy ****!
I'm not a "heavy user" and I turn off all sync and radios until I need them. In this state the phone will still recieve phone calls and text msgs. I turn on either wifi or mobile network access when I want to surf and enable bluetooth when I drive to connect to hand free in the car. I turn everything off when I'm done using each. I have all the power widgets right on my home screen so it only takes a second to turn on/off as needed. Using this way I have gone over 3 days before charging several times. I know this doesn't work for everyone, but I'd rather decide when I'm going to use my phone for what than to be at the beck and call of my phone. YMMV

Why don't you just use it normally and charge each night?
Just lazy.
Yeah, I've done all the tips and tricks and charge with power on the power off and charge, wash, rinse, repeat. Nothing works. I'm curious to see if the "free" battery they gave me will last longer.
I was in the same boat as you.
I have a fix and it should work.
turn on always on mobile data and enable auto sync
I posted a thread about getting rediculous battery and someone told me to do that and it worked.
go to settings all the way to the bottom to about phone Ans then choose battery. I bet ur up time and away time are the same. if they are that means something is keeping your phone on even tho the screen is off. doing what I told you above with a restart should fix the problem. also when you restart it its not going to instantly go to sleep leave your phone for like an hour and then check the up and awake time and it should be different. hope that helps.
and enable data when roaming.
Without specifics about what you have the phone doing and what kind of signal you have at home/work/etc, this is a totally irrelevant discussion. In my experience, the only thing that actually kills the battery quickly on the Evo or any other phone is poor cell signal.
I get well over a day on my evo... Running the netarchy kernel along with setcpu profiles. I have my phone set to clock to a max of about 384mhz when the phone screen is off.
I did the battery recharge trick and it helped a lot. I also have my display timeout set to 30 seconds.
5-7 hours before i rooted i would get 10-12 easy since rooting and loaded the.bakedsnackes rom i get avg 19 hours
sent with my evo from a secret place
Dump the Mail app and use Gmail to pop your accounts
If you are using the MAIL app that comes with the OS, that is likely the culprit. Especially if you are syncing more that one account. That can kill the battery very fast.
**try using the gmail app, and set it up so that it pops your pop mail accounts for you and pushes them to your phone. Then disable the built-in mail app and never use it again. This alone should double your battery life. It worked on the Hero and it works in the Evo.**
Do you by any chance use Yelp? I did an experiment last week with Yelp. Without the Yelp service running in the background, I would lose less than 8% of my battery overnight. With the Yelp service in the background, I lost about 50%. I've emailed Yelp to see if they can disable the Yelp service if I don't login to my Yelp account through the app.
Putting my phone on wifi made it so in the morning (4 hrs of low signal then to 50% battery), I put ti on the school's wifi and it was 80%.

I would avoid doing this. Lithium-Ion Batteries (found in the Evo and almost all other phones and laptops) can only go through a certain number of charge cycles. This method will not help prolong battery life.

I was just wondering what is the average time of battery life on your wing..mines is currently about 10 hours idle but while im using it that goes down to about 5 or 4 i just wanted to know what is the average before i call t-mobile and ask for a new battery.
A few of us here have been having problems with the battery actually. When I first got the phone, I left it clean and stock. I would do a lot of texting, make a couple phone calls, and play a few games here and there. From 7am to 1am, I would go from 100% to about 54% (18 hours of usage). Now, if I leave my phone idle for 2 hours, my battery drops down from 100% to 80%... I can't even go a full day without needing to charge the darn thing. 200 hour idle time my arse!
But personally, I don't think it's a problem with the battery... The phone is doing something in the background which is causing a massive battery drain. Right now, I'm testing my phone to see if I still suffer the same drain while in flight mode. I'll post the results HERE in about an hour from now.
The longest the battery can last is 1 week...
On a full charge, you can talk for 5 hours...
the more features you use, the more power it'll consume.. if you do a lot of internet browsing, I believe I saw GPRS Data connections use more power then WiFi.. so use wifi when available ...
also, be sure to regularly check your phone's task manager before setting it aside for long periods of time... sometimes it can be hard to notice the camera, text/mms, calender, Internet Explorer, Windows Media Player, are all running in the background while you're at the home screen...
My wing usually lasts me from unplug at 8am until plugin at midnight... power usage always varies a lot as... as you can tell.. the data connections use a lot of power... and if wifi isn't available, it uses at least 30% more power doing a GPRS Transfer -- based on the initial information i've read about the issue.

I noticed Bluetooth and WiFi taking more battery than GPRS
As long as I plug it in while I am at work to a USB cable, I don't seem to have any battery problems. I use GPRS and SMS constantly.
I spend the whole day on the phone ... between texting and I receive all my work email directly to my phone... so I'm on it various times during the hour... and it seems the battery drain is huge.
all I have done is turn the screen brightness down whenever I'm not using it, and have the dynamic overclocking on, so the processor goes down whenever its not in use ... but I still think the battery drain on the wing is ridiculous.
Well david, overclocking doesnt help
Im clocked at 247mhz, i can make it last about 24 hours using it here and there. calls about once a hour for 5 min or less, texting through the day, and occasional wifi use. at stock clock speeds, it lasted about a day and a half, but it all depends how much you use it
At 1st i thought the battery darin was rediculous as well but when u think about it when u use it the battery goes down about 8 times as fast( depensing on what ur actually doing w/ it.
Now i charge it at night and go to school with fully loaded battery 6AM, i text all the time and when i get home its around 85% 2:30PM, use it occasionally and at the end of the day after at least 3 hours of talk time its on around 30-20% i could last w/o charging it but i charge it overnight to full, with NORMAL use and not talking for about 4 hours per day so far its lasted 4 days for me. could have made it to 6 but i wanted to showoof my new phone to my friend
so battery life is not that bad just depends how much u use it, Also if ur listening to music just turn off the screen and thats a REAL battery saver. also press the power button when on the phone and etc.
Wing Battery Drain
I have improved my Wing battery drain by doing the following...
- Turn off the automatic weather update on the Today Plug-in
- Check my emails manually (do send receive when I am ready to read)
- Suspend device when not in use - need to use device lock app.
- Update ROM to PDA Viet v 14 (thanks to easy instructions from David)
With the new ROM and the device locked - even the accidental press of any of the face buttons (when phone is in pocket) turns the device back on - even though the screen remains locked (due the Device lock app). Is there any way to suspend the device completely so can only be turned on by hitting the power button only? I would still want to receive / answer calls etc. without having to hit the power button....
Go to settings, Lock ... and there is an option to lock all buttons except the power button when device is powered down.
I am trying to fix my sisters Wing (I have a Wizard). I have tried disabling background programs, as well as setting things to be more gentle on power usage, and still she loses battery like crazy. I know the Wizard had some battery drain issues with certain WM6 cooked roms, and a cab fix helped. Does anyone have a cab fix for the Wing? Also, reading in this forum section, it seems that the Wing doesn't always disable background programs. Would you suggest a third party task manager to "pick up the slack" or does it not matter, due to the nature of the winged beast?
I appreciate any suggestions. While I am new to the Herald, I am "old hat" on the Wizard, so I do have a general understanding of how the HTC devices work.
Thank you in advance.
I have read a lot of bad stuff about battery life with every rom except the OME t-mo. I had the PDA viet and battery life was terrible, With the stock rom it is at least 4x longer.
hello ive the same problem with the last 4 wings ive and ever since ive switch from the stock Tmo OS and upgraded to the TouchFlo OS, Ive noticed a huge differnce with the battery life even overclocked
If your will to taking the risk ide say go for it, i jus started messing around with rom and i got say its a big improvment from the original wing which i was ready to throw against a wall!!
I have Touch Flo on my Wing, and if I charge it to capacity I usually only need to do so it every other day so long as I don't play any NES games on it. I keep the wifi off if I'm not using it of course. I have it dynamically stepping the CPU in a range from 100mhz to 234mhz. It really seems to help extend the battery for me, while still giving it the tiny extra kick it needs to run nes and sms games.
My wife has the official wm6 rom on hers, but is also dynamically overclocked as mine is. She needs to charge hers nightly, BUT she also plays solitaire and bubble breaker daily.
Overall it's on par for battery life with my prior motorola phone, which I never used for anything but regular phone calls. With that in mind I'm not necessarily impressed, but am definitely content with it.
I've had HORRIBLE battery life and AWESOME battery life, all within the same week. lol
There was a problem I had at one time, where filesys.exe would take over all the CPU and kill my battery.
Here's what I do, though.
Dynamic overclocking/underclocking
Turn off GPRS when not in use
Disable Push Mail
Turn off WIFI and Bluetooth
Turn the screen brightness down
Turn off the screen altogether, even when on a call, unless you need to see what's on it
There's a few tweaks out there that deal with enabling the power saving features on L2TP and stuff...
First post here-
I've had my wing about a week now and have a question concerning battery usage.
It has always been my understanding that batteries will develop a "memory" if you charge and recharge them under their full charge capacity.
i.e. if you use it down to 60% and then charge it to 100% it will remember that and not use the full original 100% charge. obviously over time not just from a single "half charge" like that.
So since every time you connect it to USB to sync it begins the charging process, won't that wear down the battery and make it develop such a memory?
Is their anyway to connect to to the PC without having it charge?
I have always preferred to have any mobile device drain it's battery to nearly empty before recharging to try and minimize the memory effect.
Thanks

Today's lithium ion batteries do not develop this like older rechargable batteries. You can plug your phone in at any time without worrying about losing battery capacity!
Thank chris30_2001, good to know.
oh and it's ALWAYS lupus
I listen to Streaming Radio with my Wing at work all day. I get approximately 4 hours of listening time before I have to swap out with another fully charged battery.
I use PBar to shut off the screen while listening.
I'm running the touch rom without the actual touch. I can't remember which one it is. I spend at least an hour a day gaming (text twist, random solitaires) on it. I usually hit up the web a few times a day for 10 minutes a shot. I use it as an ebook reader. I send txts constantly. I talk about half an hour a day. All this leaves me with about 30% - 50% of my battery by day's end. Now, if I turn on bluetooth all day it will end up around 18%. Wifi is such an evil power hog I never turn it on, EDGE is fast enough for me. I charge my every night under my pillow (it's my alarm too). Battery life has been the same since I got it about 6 months ago.
Edited to add: I also do some dynamic underclocking for things that don't need a huge amount of power, like my budget program, etc.
Ok so I received my Vibrant on Monday and so far I am in love with it. Their are three things that bug me, however.
1. Battery Life is TERRIBLE. I know, I know-This has been discussed before but I did everything the other threads said and still no difference. On my phone, I will leave it on standby and it will drop 8 percent in like an hour and a half. Somethings wrong. Also, If I play the Sims for two hours (like I did today) my battery goes from 98% down to 45%. Is this normal?
Just to point out what I have going on with my phone:
- Brightness is turned down COMPLETELY. Automatic brightness is turned OFF.
- 3G is always on. Could this be the culprit?
- I have a completely black background.
- Last I checked, it said my display was taking up 60-70% of my battery usage.
- As stated above, Sims DRAINS my battery. Either somethings up with my phone or Samsung should have made sure the Sims doesnt kill the device.
2. The second I take my phone off the charger, the battery goes from 100% to 98%. Can I fix this? Its kind of annoying...
3. Problem with the Sims. Im not sure if any of you have this issue, but whenever I tell my Sim to watch TV, the app shuts down and takes me back to my home screen. Any idea why its happening?

1. Leaving a phone in 3G all the time is not a good idea, if you have WiFi near you you can connect to I'd use WiFi instead, it has less battery drain then the antenna that is constantly searching for 3G signal - unless you are in the area with bulletproof 3G coverage of course.
2. It seems like this bug is common 100% jumps to 98% once you unplug the charger, are there really any accurate battery meters on the market?
3. Can't help you there, not playing the game on my phone.

alright thanks. im in phoenix here so i am almost always in a 3G area. I guess i'll leave it on since i rarely dont have 3G
I also read on multiple forums including HoFo that 3G generally consumes more energy then WiFi.
sims 3 fix
so my girlfriend was complaining about sims crashing when she watched tv or relaxed on the couch. i fixed this by moving both the sims launcher app and the sims game app to data/app.
I normally use Edge simply because I don't need Wifi or 3G on unless I'm doing some heavy data transferring.
Currently I'm at 61% battery, which means my phone has been off the charger for 16hours. Its not a fluke either because its just normal use for me. I normally take my phone off the charger at 6am and I plug it back in around 11pm.
Prolonged GPS, Wifi and 3G will eat your battery. I'm not saying don't use the services, but you give up one for the other. I personally like to have awesome battery usage until I'm out and about and really need to use my phone.
I'd recommend you call T-Mobile customer service and have them diagnose the problems you are having and issue a replacement if necessary.
Based on my experience, battery life is excellent, probably the best I've seen in any smartphone in this category. Battery usually last easily through the day with heavy use, including:
- having 3G on all the time (and frequently switching to edge and back)
- 2 email accounts using push (gmail and exchange)
- gps on all the time
- google latitude running all the time
- facebook and twitter sync'ing every hour
- fancy widget sync'ing every two hours
- Newsroom harvesting 12 news sites in the background
- occasional picture (3 or 4) a day
- web browsing and searching
- xda app for reading and replying to this forum.
- bluetooth is always on
- wifi is on from 8 pm on.
I charge the phone through the night, unplug it at 8 am, return home at 8 pm and put it to charge around 11 pm, with still 50%. Brightness is set to auto. Phone is not rooted or modified in any way.
You bought a high end phone that should perform as such. You are supposed to get the most out of your phone, not turn off its features. I wouldn't listen to those who claim you should turn off everything and dim the screen. What's next, not using the phone to preserve batteries?
That's just my two cents.

Yesterday, I was using the Google navigation on 3G network with the phone connected to a 500mA car charger. After 1hr, the battery dropped 20%...Anyone knows if a 1000mA car is enough??
Tonight, I was watching a Youtube HD video on 4G network (2/3 bars on 4G) with the phone connected to a 1000mA USB wall charger. After 10min, the battery dropped 2%...Well, even 1000mA cannot compensate the consumption of the battery.
The power consumption of this phone is ridiculous. Something must be wrong with the system/circuit design.
NOTE: I'm not complaining the battery but the power consumption of this phone. The charging cannot compensate the usage of the power. Think about a laptop. It's even more powerful, but you can use it freely without any concern about the battery as long as you plug it in an ac adapter. Why can't Epic 4G do this?
man i been seeing the same problems i was listen to the sprint radio while hooked up to the charge and would see it stay at the same percent for about a hr before it went up 1%. this battery issues is making me hate the phone right now and i cant find any rapid charge programs or settings for this yet. cant wait for some custom rom to come out that hopes to fix some of these issues
yup 4g is a battery hog which is why people are complaining about battery life,I suggest you turn it off, it's just not worth it IMO, which too bad cause we're paying extra afterall.

I saw a post this morning. The 3G even consumes more battery on Epic 4G during browsing. so we can expect even worse under 3G.
I'm on my third Epic and they have all had battery drain issues. Battery manufacture dates ranged from July to mid August. Right now actually, I'm streaming some radio over 3g and have an AIM client running in the background and the batter is slowly draining while plugged into the charger included in the box.
I have tried a factory reset just to be sure any apps I installed weren't affecting anything and still no dice. Even with running navigation in the car while plugged into a usb charger the battery will drain about 1% every 5 minutes or so. I'm probably returning the phone for good in a few days
This is with 4G disabled, using SwitchPro widget to enable 3G. I also have background updates disabled(under accounts/sync), I manually do them periodically.

That shoul be more than enough. I use a Motorola-branded 850mA microUSB car charger (quite cheap on Amazon). On a recent day-long driving trip, it was sufficient to maintain the battery level while streaming audio over 3G and simultaneously running GPS tracking. I don't think a 500mA unit would have handled the load, however.
I'm really starting to think this phone is an epic fail. I get from 1.5 hours to 2 hours of use from a full charge! Thats with everything off, 4G, wifi, bluetooth, GPS. The sprint store manager wouldn't exchange my phone because he said their is nothing wrong with it. If it takes 6 hours to charge and then I get 2 hours of use, this phone is worthless to me!

Yeah that doesn't sound right. I think most people would have a hard time making it last only 2 hours. Maybe gaming while running WiFi tether.
Keep in mind with CDMA, the lower the signal to the tower, the more power it takes to keep the connection active. For GSM this is less of an issue. How is the signal where you live?
An interesting side note. I plugged in my charger for my Bluetooth which is only 180ma and it went from 70% to "Fully Charged" in 10 seconds. When I unplugged the charger it went back to 70%. It really didn't like that low power feed.
Sorry if it came out orange. I used screenshot the app and that's what i got. Anywho, its a perfect combo what I've done. See the up time, nearly 15 hours up time. I only lost 35% of life during the time too as you can see how full the batt is.
Remedies: Autokiller set to extreme. ATK: Set to aggressive, with auto kill set to when screen is off. Interval every hour. Cachemate: all settings lit up, so it clears about 12-14 MB every hour or 1-2 every manual clear. Set CPU: Conservative 1000/100 with set to boot. Notice, set CPU resets itself every reboot for now, just make sure your good.
Then you should be good as I have for TWO days on one charge nearly 24 hrs ago.

I would love to see more info/screenshots on this. The one SS you included somehow ended up thumbnail sized only. 2 days is nuts, anything over 24h would be.
hey guys
I've been really happy with the battery life on my epic - I get about 12-14 hours with on-off use, 4G off. My battery is sitting at about 35% after playing a bunch of games for about 3 hours in between classes and it has been running off battery for about 8 hours, browsing the web, sending texts and downloading apps on both 3g and wifi.
I'm using Advanced Task Killer and its set to kill aggressively every half hour - it kills all apps except Juice Defender, itself and LauncherPro.
I'm running LauncherPro - if that matters - doubtful, but I didn't like touchwiz. And I'm running JuiceDefender on default settings. Basically it kills the 3G radio when screen is off unless its transferring > then 15kbs of data. The normal radio remains on for calls/texts.

What is the EVO fix? I'd love to try some extra tips.
My two cents - a typical day puts me at home and at work for the majority of the day and night, which both have wi-fi. I've turned off "look for open networks", "never allow wi-fi to sleep" and I leave wi-fi on. After a full night of charge I took the phone off of the charger at 11am on Saturnday and it finally turned off Sunday at 8pm - 33 hours is pretty darn good, almost two days. However yesterday I took the phone off the charger after leaving work at 6:30pm (so no wi-fi, just 3G) and in just an hour with watching a 15 minute long normal quality YouTube video, a few texts and a short phone call I was down TWENTY PERCENT. What the heck.
Over wi-fi, like I said, I'm good - great battery life since I'm not waking up the 3G radio to do anything. But when I get out of those wi-fi areas that's when my battery starts to drop. Anandtech is getting similar results with awful 3G battery:
http://www.anandtech.com/show/3891/samsung-epic-4g-review-the-fastest-android-phone/8
Something is wrong with the 3G radio, and I hope Sprint & Samsung seriously do something about it.
You guys are all failing to look at "Cell standby" details.
Time without signal on this phone - no matter WHAT coverage area you're in - is ALWAYS > 50%. This is bull**** and a Samsung software issue. Take a look for yourself.

I never had a problem with but I've been reading many having a problem with "Cel Standby" going out of control. Mine it at 17%. Highest I have saw it was in the upper 30's range after a full day (14hr)
Just an update on my usage from Pg.1:

I am not seeing this issue. Never seen it above 3%. Besides most of the battery is going to the screen it seems. I am actually wondering if it reporting the usage correctly. If the screen was really take that much of the power, it should be lasting a lot longer.
People getting great battery life are reporting they are using task killers and data connection blockers. That isn't even where they majority of the power goes. The system tells us it is going to the screen. Not the tasks or data connections. It seems counter-intuitive.

Turn airplane mode on then off. (settings -> Wireless & Networks)
This will solve the problem until the next time you reboot. You must do this after every reboot.
I'm working on a more scientific breakdown of power consumption. But here are some brief findings.
The highest power consumer is the display. Even on the lowest brightness setting it consumes more power than a normal LCD (I'm comparing it to my Evo). If the display is only showing a black background it is lower power, but then again if all it is showing is noting, it may as well not be on at all. If you actually want to display something on the screen, it consumes power like it's going out of style. So much for Super AMOLED being a power saver (total and completely false.)
The next highest power consumer is the 3G radio. Under similar circumstances (similar signal strength) the 3G radio is consuming more power than the 4G and Wifi radios combined. Wifi seems to consume the least, followed by 4G then 3G. This is crazy and if not fixed might be unacceptable.
Next is background apps, most specifically anything that uses the network (email syncing, social networking and location reporting services like latitude) being the worst. The sync settings on the Epic are not as robust as the Evo and I've struggled to gain control of gmail without just setting it to manual only. Do not use latitude and although some will speak out against task killers, having one to keep "maps" at bay is worth it alone.
Then there are more obvious things like live wallpaper. Or specifically anything using the CPU / GPU and GPS.
More to come, but right now, something must be done about the 3G radio and GPS or this phone could live up to the moniker of Epic fail. I really hope Sprint and Samsung are doing something because otherwise if the phone worked as it could, it would be awesome.
I had everything turned off. No email, no sync, no wifi, no gps, nothing. I fully charged the battery and unplugged it before I left. Display was never turned on. I wanted to see a completely isolated battery test. The only applications I had active according to my task manager was Launcher Pro.
Time on 10 hours 20 minutes
Battery life left 60%
Battery used 40%
Cell Standby - 40%
Phone Idle - 30%
Android System 20%
Calls (1 missed call) 5%
Display 3%
Maps 2% (Why does maps show up?)
Again this is with absolutely 0 use or syncing going on. Left phone at home, turned on and immediately checked stats when I got back from work.
According to this small test I can't even last a day on a full charge even if I left it completely alone.
Thoughts?

In 1.5 day of standby with every radio off and no sim, my phone only lost about 5% with stock JI6.
I think it is a cool idea. I find that 5% usage for one missed call is very bad. I have really suspected that voice calls kill this battery and that seems to add evidence. 5% for a missed call? That is messed up.
I think this is the aspect of battery life that doesn't get addressed enough: drain during standby. Of course everyone expects to lose some power while the display is on and syncing/other processes are running--but what about when the phone is left untouched? Here are 3 ideas:
3g is a notorious battery drain even when the phone is not being used--use 2g instead.
Freeze or uninstall media hub and other running processes that attempt to run/connect to servers in the background. I removed dmservice, media hub, and all drm processes and this seemed to be helpful.
Use a custom rom--these appear to hold power in standby better than stock roms do.

Cell Standby indicates that there is an activity that polls something from the network.
if you are so concerned about what it might be, you can see when and how much data is being used by going to your TMO account online and check for the data usage - one of the good features TMO put in place is actually tell you when your phone connected to get what amount of data over the data connection, does not tell you what it was doing though.
Yeah, something is going very wrong in your phone. When my phone is on standby with just 2G on it drains less than 1% per hour. I would definitely recommend getting rid of the drm service and media hub (and Daily Briefing). I also use Autostarts to keep all kinds of random programs from starting at inappropriate times (Really Slacker, does your app need to launch every time the time zone changes?)

I wonder if Samsung's definition of "standby mode" is what the rest of us call "off".
I've never had any kind of batt life with this phone...charge everday overnight...start work at 8, use here and there for navi (around 10 mins max, maybe 2x a day) about 30 min avg talk...and mp3 player...get home by 4 and always at 30% or (most often ) less...have had stock/ bionix roms, never changed, no matter what build....it's pathetic..called tmo, they said there are no known issues with batt on this phone...wow...do a google search on it..anyways, they are sending out a new batt..I hope I just got a bad one...seems very random tho, some ppl have all radios on ,screen all the way up and get 10+ hrs...if i left my screen on (say navi on) for more then an hour straight I'd be out of battery..very weird..praying new batt is better...

Does it seem like youre just not getting the battery life you should from your phone? Do all your other friends keep going while you slowly putter into a shutdown? Well pout no more! Simply follow these steps to clear your batter information from the phone and your phone will act better then new! :)
1. Charge phone completely, leave plugged into power
2. Boot into recovery
3. Wipe battery stats
4. Reboot to normal
5. Remove power cable
6. Drain that sucker all the way
7. Recharge fully
8. Rejoice!"
I turned my phone off today. Then I left the house. When I got back the battery was glad to see me. Seriously, I've read just about everyone and almost started my own battery disturbance thread. I've come up with a new thought at least for me. I don't care any more. I have electricity. I have a spare battery and a charger. If my phone wants to last a whole day. Yay! If I use it more because of some game with angry birds or cards or dice, great. I've reached that Mark Twain moment somewhat tweaked when he said,
“Age is an issue of mind over matter. If you don't mind, it doesn't matter.”
I'll tweak it with the last 27% of battery left in my feeble vibrant to:
"battery is an issue of mind over matter. If you don't mind, it won't matter".
Enough already I say! Lets spare the air. Batteries are meant to be used
Back to the regular reading of all the battery threads now.
I think I had the same issue as you. Cell standby was the biggest drain. When you tap on that, do you see 50% time without signal? If that's the case, this seems to be a bug in Android which was somehow introduced in JI6. The best solution I've found so far is after every boot to put your phone in flight mode for a few seconds and back. This fixes the radio glitch, your time without signal should go down way under 50%, and battery drain should stop. Hope that helps.
You should recondition your battery:
Fully charge
Reboot into recovery wipe battery information
Reboot into OS
Unplug power cable
Let battery FULLY drain (do not plug in until fully dead)
FULLY charge battery (do not unplug until fully charged)
This reconditioning should be done after every ROM flash.
Just awful battery life. Like recharging the phone twice a day without using the phone for calls, browsing or apps. I have full signal strength at my desk and it just sits there. I haven't installed many apps, mostly quadrant and winamp, but I can't use winamp because the battery life is so bad. I tried returning it to Radioshack, but they won't listen and insisted that I install a task killer and it would fix my battery life.
That's stupid, so I'm going to call the regional manager about it, but in the mean time, I'm trying to bump charge it by putting it on the charger while turned off until the orange light turns to green. Then you unplug it, restart it, turn it off, and start over. The amount of time it takes to get to green should slowly decrease.
Mine has been doing this for 14+ hours now; it takes about 3-4 hours each cycle.
Can anybody advise me on what to do next?
Mine regularly goes 12+ hours without really needing a charge with lots of texting, a few calls, and lots of data. Then again, I'm using my EVO's nicely conditioned battery.

You have every right to return that phone within 30 days. I personally am seeing excellent battery life on the shift compared to my old evo, so there is definitely something wrong. If need be threaten to return the phone if they won't exchange it, and tell them you are going to purchase one from a corporate sprint store, or best buy instead. They can't make you keep a defective product.
You're the customer, they work on commission, you make or break their paycheck so if you return it they don't make money off of you. They need your business. Remember that.

If the RadioShack you bought it at is refusing to accept a refund/exchange within your window then you call the BBB or get on the horn with their general manager or district manager. The phone is defective and should be exchanged for a properly working phone. Usually, RadioShacks put the GM/DM or manager's cards right on the main counter. Go in, pick one up and call right in the store and see how fast those monkeys get you a new phone.
One of the complicating matters is that I bought my phone from the Radioshack nearby my parents house, a couple of states over. Technically, I should be able to return it to any Radioshack because I have the paperwork and packaging, but I visited 3 stores yesterday and they all passed me along to the next, claiming to be out of stock, and the third flat-out refused to do a return.

Take it to a Sprint corporate store with all that paperwork. You should easily be able to return it to any RadioShack though.

I work for Sprint Corporate and unfortunately we wouldn't be able to accept the return. What you can do is this.
Go to a radioshack, sit outside the store and call them pretending to be a new customer interested in the shift, and switching to sprint from verizon. See if they have the phone in stock. Then once they confirm that they have it, walk in with your phone and all the paperwork. Simply explain the situation and the runaround you've gotten. They can't tell you they don't have the phone in stock. Their district manager would be an actual corporate sprint employee, you would be able to get his contact info from either radioshack or from a manager of a corporate sprint store.

Sounds like you have a wake-lock issue. Have you checked to see if your time awake and uptime is the same?
Do you have wireless sync turned on in WinAmp? That killed my battery on the Heroc for some reason. I keep it turned off until I want to use it.

Usually wake time is ~1 hr while uptime is 6-7 when the phone dies. I also have winamp wireless sync turned off.
I ran my phone with multiple long phone calls, texts, and data. Using different apps and such I charged the phone for 30 minutes on a car ride and then on the way home played my mph3 player in my car while not charging. When I got home I couldn't believe it. I've been on my phone sine 10 this morning so about 5 hours and I am at 94% battery. But I am temp rooted and all bloatware removed. Love the battery.

I had some pretty terrible battery life when I first got the phone. After a week, I did the following:
- Factory reset
- Configured google, exchange and my "basic" apps
- Ran PRL and Profile updates
- Set display to about 15-20% brightness
- Charged phone until the light turned green
- Then did a bump charge (turned phone completely off and reconnected it to the charger.)
Battery life for me more than doubled.
I was getting pretty terrible battery life, and the battery was getting pretty hot, letting the battery completely run out of juice, then charging it to full with the ohone off, seems to have REALLY helped.

Is your phone getting Hot during this time?
I was able to get my phone to last 48 hrs on light use and atleast 12 listening to howard stern all day and playing games.
A little list of things to do, check and or disable;
1. Use spare parts and find out whats killing your battery ie partial wake usage, cpu etc.
2. Turn your window animations from all to only some animations
3. Turn off automatic display and keep it around 20-30%
4. I have auto sync off on all my appz (E-mail, Gmail, Facebook etc.). I update my E-mail and such manually.
5. Turn off data when not using it. I find data accounts for around 15-25% of juice used and thats just when on idle.
6. Only use widgets on the homescreen if you really have to (Running widgets use a lot of power over time)
7. Use Android Hackers tool from the market and it will break down how long your cpu was in a certain state. ie my cpu spent 65% at 245mhz and 28% at 806mhz.
8. Keep off 4G, Bluetooth, wirless networks for location and GPS if not using it (GPS uses less power than wireless networks and is more accurate anyway) I assigned Quick Settings to open when I hold down the search button. That makes it easy to enable/disable any of these setting within seconds.
9. Turn off google talk and make sure it doesnt sign in automatically (most people dont realise this)
10. Turn screen timeout to 15 or 30 seconds (if longer your phone can keep the display on accidentally while in your pocket if a button is pressed, wasting power)
11. Dont use a task killer unless its to kill an app you know drains your battery and therefore must be closed to save juice
12. Check your apps. Some apps keep using cpu etc because they were not programed correctly. (some appz I've found to drain my battery very bad are; Yahoo Mail, Craigslist, AndTorrent and the market if a download is hung up. There are a few others I cant remember off the top of my head) If your phone is getting hot for no apparent reason this may be the cause.
13. Calibrate your battery by bump charging (charge your phone till its full while on, turn it off and charge till its full again. Then bump charge it around 5-7 times) Wipe battery stats if applicable. If you have a car charger, plug your phone in on the way to work to account for the little bit of drain that occurs once the phone is fully charged yet still on the charger.
I installed Juice Defender and right now it's 6:30pm and I unplugged at 8AM and I'm at 54% battery.
Usage has been like Tapatalk, sent about 200 texts, read my Google Reader account and Pulse. Played some games for like 20 minutes too. WiFi and GPS have been on all day.
When I'm actually using the phone it doesn't really help but when my phone goes idle, it goes into super battery saver mode or something because it only goes down like a percent every 2 hours on idle.
Looking at JuicePlotter from about 8AM to 10AM it dropped 80%, from 10AM to 11AM when I was doing work and not using the phone as much went from 80% to 75%, 11AM to 12PM went from 75% to 74%, then from 12PM to 4PM it dropped to 55%. I took a nap and just woke up at 6PM and it's 54%.
I've been reading JuiceDefender doesn't help but yesterday, from 8AM to 6PM it was down to 20%.
So if you want extra battery life I recommend trying JuiceDefender. I'm just using the free version on default.
Of course if I'm in super power user mode it drops like 10%-20% an hour but if you only check your phone throughout the day and when you have to wait or in the bathroom or something and it helps tremendously imo.
I started off by turning my screen brightness down and making sure most notifications were off or every 15 minutes, ie twitter. Have been impressed since day 1. I have heard nothing less than 10 hours on a normal use phone. I typically get 16+ with wifi and gps going.
The battery is a very strong point for this phone, so if it's not preforming, defiantly try talking to a manager till satisfied
I had a similar problem to the point I almost returned the phone. Before returning I tried:
- Factory reset
- Bump charged the battery
- turned brightness down
- GPS off
I have syncing set accordingly:
- weather every hour
- gmail and exchange push
I didn't add any apps for the first couple of days, then slowly added one app at a time and will watch my battery life. This has completely changed my battery life. I went from 2-4 hours to currently 9 hours 53 minutes and at 64%.
