at work today i guess i had a bad signal and i noticed i lost over 20% in less than 8 hours. whats the cause of this and is there a fix? i also notice the phone runs like **** on a low signal, very sluggish even when overclocked.
More power is bein pumped into the radio to keep the signal strong(er). Airplane mode is your friend. As for being slow, I don't know why but I also experience slowness in low-signal areas.

must be an android thing because i never had this happen with winmo or my palm pre.
Turn off 'Background Syncing' in Accounts & Sync settings. That will greatly improve both your battery life and phone slowness in low-signal areas. I have terrible signal in my work building too (would almost completely drain my battery in an 8-hour day), and ever since I started turning off Background Sync while at work, my phone only drops to around 50% in a work day.
I really think it's more the syncing that sucks the battery down in low-signal areas, not the radio having to broadcast stronger.
I have bad signal strength at my house. I also have a Airave to make up for this however since it does not provide 3g my battery will drop like mad when I am home.
The fix for this in my case is to turn off my mobile network when I get home that way I can still receive calls and texts but it basically tells the phone to quit looking for 3g signal and sticks to just the basics.
I then use my wifi while at home to get on the market or have my gmail and other apps sync with the phone.
Hope that helps you out and you find a solution that works for you.
I noticed MUCH moreso on CM6 vs. Fresh 2.3.3 what a significantly negative impact having background data enabled in a low signal area can have on the phone. My workplace is a consistently terrible cell area and since switching to CM6, I have been not only plagued with terrible battery life (like 10-15% per hour with minimal usage!), but the phone was running like absolute poo.
Today I checked to be sure and to my surprise, background data WAS enabled! I promptly turned that off and the phone returned to it's former CM6 glory and battery life returned to non-workplace goodness.
I have a bad signal at work, so I force it to roaming. It saves my battery and my phone is more reliable. Just be careful not to use too many minutes or too much data.

How do you set it to roam? Is this a setting or is there a code i can type in whenever I want it to only look to roam, then another when i want it to go back to regular, or even if i only want it to look for 1X or only look for 3G? One of the client sites i regularly travel to has great roaming 1X speeds once i can get it to switch to that but it must also have a weak roaming 3g tower somewhere because its always on 3g with one to zero bars.
I'm on Fresh though i'm apparently going to have to look into CM6 in the near future. I love this place.

You have a few options...
1. You are running Fresh on your Hero? Use the modded phone.apk from here: http://forum.xda-developers.com/showthread.php?t=745092
2. Use the PRL hack...you'll have to search for it, although I think the link is in the thread that I linked above
3. Download the app "Roam Control". Disclaimer, I am the dev, and yes it costs money.
4. Flash CM6.
Just recently stumbled upon an app called shutupbattery saver
It automatically kills your data when signal is low. You tell it what signal strength turns it off. Does wonders

No..not really. I had several TP2 windoze phones since May of this year and went back to my Hero. The battery life on the RC1 build when you follow what has been said here,will give you way more life than any of the phones I have ever had.I was lucky to see 4 hours of life even with little usage with the TP2's. While my CDMA Hero does drop to 80% with everything turned on in 7 hours,it slows down considerably after that. Just with mild web crawling and 20 minutes of talk time it took well over 60 hours to drain completely last weekend after resetting the battery stats on mine with everything turned off. I actually had to use it non stop for 4 hours to drain the thing so it would shut off and be drained. Any phone I have ever owned has always done better after letting them drain completely and then charging them to 100% a few times. We have 4 of them in our home,and mine last longer than any of the others..the other 3 are stock 2.1.6 roms.

Why are people complaining about losing a measly, small 20 percent of battery in 8 hours? I'd understand if it was 35 percent or more, but seriously? you're complaining becuase your battery can last 40 hours? Wow...
CM6 RC1 with collin_ph battery tweak rules the world.
what i do to save my battery i change the settings on my advance task killer Menu>settings>Auto kill level(crazy)then also change Auto kill frequency(when screen off) and that really seems to help me
You could also look in to JuiceDefender. It shuts off 3g when screen is locked, turns it back on for either 1 min every 15 mins or 2 mins every 30 to sync.

not everyone runs the froyo rom. at least i won't until a sense port comes out. and yes when the phone has a low signal it runs like absolute ****.
I'm having this problem also on CM6. Unplugged my phone this morning, full charge. Went to the gym at 11:30 and worked out for an hour and a half. There is no signal in my gym. The phone was completely dead when I got back to my desk. So basically the 80% battery drained in 1.5 hours (assuming I lost 20% between 7am and 11:30 when I went to the gym) It was not nearly this bad on the stock ROM. I just insggtalled collin_ph but I doubt that will help in this scenario. I might just have to remember to put it in airplane mode before going to the gym.
My bigger worry is when I'm out riding my road bike in the country. If I'm in the middle of nowhere, the battery will drain FAST... and thats the place I'll likely need to call someone in an emergency.
In my opinion there are key steps to insure a good battery life I perform this process every time I turn my phone on for daily use
First in settings/wireless/mobile networks I turn off data also roam and I change the signal to home only then in account and sync I turn off automatic sync and back ground data also i make sure that wireless is off as well then I turn my attention to applications and I clear data and force close any running program I'm not using for example gmail e mail browser Google search blue tooth I only force close apks that I know wont affect the system and how it runs also I should mention that this is done after I had calibrated my battery also I in spare parts I choose to make my end button put my phone to sleep these two steps are only done once now back to the process I run the over clock widget with dead3nce 9/14 stable kernel but also with every stable release he has put out I set the feq to 710 Max and 710 min and diff feq when screen off with 384 Max and 245 min this setup gives me high performance and long battery life I get 14 plus hrs with heavy use before ill hit 50% so u can imagine with moderate use will b or even standby time so I basically kill my phone if I'm not using it its in what I think is its lowest power state that I can get it at but its still on and ready so wen Im ready to use it I activate it and turn on what I need when I'm done I kill it again short of turning it off just thought I put this out in case it helps also I'm running cm6 rc1 and the 8/22 nightly I switch back and forth because of themes but the process is the same and so are my results so hope this helps good luck

It's 3G. Turn off your Mobile data when you going to be in an area with a bad signal for a long time.
As someone else said the collin_ph battery tweak works wonders too.
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.
As I'm looking through the threads I'm seeing people getting terrific battery life. What can I do to get better battery life besides all the little tricks like cutting of gps, syncing, and back light etc? As I stated in another post I run the tunein app for 2hrs and my phone is at 20% HELP!!!
Stop using tunein/find alternative? I'm not exactly sure what the application does but I'm sure there has to be another application that offers similar functionality in the market, that might be easier on the battery.
powered by the tears of a million orphaned alpacas...
I've tried a alternative. I've tried the app for the actual radio station still get the same thing.
I use Tunein Radio since it's one of my favorites apps and have no issues whatsoever ... I mean it's normal the battery usage since it's streaming media.
Turning off the 4g made the biggest difference for me.
I'm usually near wifi, and with that on all day I SOMETIMES end up w/ <60% battery at the end of the day.
So just kick a man while he's down why don't ya!!!
Try this:
1. Do a full reset
2. Fully charge the phone. Once light is green, Let it stay unplugged for a couple of seconds, turn off the phone and plug in again. When light turns green again (may take up to an hour). Repeat until the green light appears almost instantly. This may take anywhere from 4-10 cycles.
3. Run the phone stock for one complete cycle. Don't add any apps.
4. If you have no problems, charge the phone then try adding one app then let the battery cycle again.
5. Keep adding an app after each cycle and monitor your battery consumption.
This way you can find out if the issue is your phone or the app. I know this isn't a quick fix, but it will help you dial in on the problem. I had similar problems as you before going through these steps. One of my cycles only got 2 hours of life before dying. I now get 15 hours of medium to heavy usage consistently! I am currently at 15 hours 5 minutes with 32%.
why dont you stop using apps to "fix" your battery and use the internal battery monitor program to narrow down exactly whats causing your battery drain?
settings>about phone>battery>battery usage
keeps a running tab on whats been using your battery since last unplugged.
if its cell standby, that usually means you are in a place that doesnt have service too long.
display is just screen being turned on.
android system is basically stuff installed in android. such as email, surfing the web, the market, etc etc.
see what that tells you. dont cover up the problem. get down to its roots. my phone completely stock got medium usage and lasted almost 9-10 hours.
Good points, newkidd. Finding the root cause is critical. However, I'd like to add that just because Display or Cell Standby is the top battery user at any given point in time is not necessarily a bad thing.
For example, if you were to unplug your phone in the morning but then forget it on the kitchen table when you leave the house for the day (No, I've never done that!), you'd see that Cell Standby was the top battery user for the day. But that's expected with a properly running phone that sat all day with 0 usage.
On the other hand, if you did nothing on your phone all day but turn it on every 5 minutes to check the time and then turned it back off, then Display would be the top battery user. Doesn't mean there's something wrong with the display or settings. At least not if your battery still lasts a full day. It just means the display was on a lot.
However, if your battery is down to 20% after only 2 hours, something is definitely wrong. Tunein is a streaming audio app, right? When you use it, are you in a good 3G (or 4G) coverage area? If the phone is having difficulty keeping a strong data signal then a streaming service could definitely eat up more battery than normal. How long does your battery last when you don't use Tunein? Or have you tried using it while connected via wifi instead of cellular data?
I'm starting to come to the conclusion I'm in a bad coverage area when at work. I left my at home today by accident and it was still almost full battery. I haven't tried using wi-fi.
Poor reception kills your battery QUICK. My house has horrible reception and for the week I was battling the cable company over our internet (no wifi) my phone would only last a few hours. Last weekend when I was home most of the day, so using maybe 85% wifi, my battery lasted the 18.5hrs until I went to bed. And I'm a heavy user. 3 gmail accounts synced, screen at near max brightness and lots of screen on and data use.

my work
My work as well has horrible reception. We run a lot of electronics and are next to the airport, all bad for cell signals.
I try to stream music, but it is a crap shot depending on the day.
I have an audiobook that I listened to all day, with no significant additional drain. However streaming music gets me about three or four hours.
I work in the middle of Houston, TX, so I should be covered by excellent 3G and 4G signal. But at my desk in a corner office, windows on 2 sides of me, on the 6th floor of a 20 floor building, I get intermittent 3G and have never gotten a 4G connection.
Although that's better than when I was on the 20th floor for about a year. My desk was right against the windows but I couldn't even get a cell signal, much less 3G (no 4G at the time). I had to put my phone on airplane mode when I got to the office or the battery would die before lunch just from trying to get a cell signal. I could change the settings to force roaming only and calls/texts would work OK, but still drained the battery quickly.
Fortunately, we have wifi at the office so I connect to that every morning now and everything works fine. It's just annoying that I can't get 4G at all. Can't get it at home either (in a house, right by the window), even though the Sprint coverage map shows that I should. I can zoom in to my address and it's in the dark blue (best available) coverage area that should mean I can get a 4G signal inside buildings - "You will be able to use 4G data inside most buildings, in a car, and outside." Nope. Not unless I stand outside.
Back on topic, a poor signal will eat the battery for lunch...
no 4G at all here
I am annoyed that there is no 4G in Phoenix at all. 4th or 5th largest city in the country, (depending on the study), and we get snubbed.
Thanks a lot Sprint
Exactly! Where's our 4G in Phoenix. I remember reading about some test market thing with the valley, Clearwire and Sprint about running WiMax and nothing ever came of it. Oh well, guess we just have to be patient.
My battery life is great on my shift. Still stock, having issues getting root through my laptop, but I usually get a whole day out of my battery. For the first time I'm actually impressed with android battery life.

I'm trying out some things today for battery life, will post with results tomorrow
Problem is Android Market makes it way too easy to download a crap ton of of apps to the point that your phone slows to a crawl. We live in an always connected world, but this also means we need to be more aware of what and whom we interact with. Be careful out there kiddies.
my company blocks cell signals for some asinine reason, but the worst part is that there is reception sometimes, so my phone is constantly searching for a signal throughout the day. i'm certain this is causing some unnecessary battery drop, and these days i'm awake and active for 16 hours a day and really want my battery to last that long. it wasn't a problem on previous phones of mine, but this phone uses a lot of battery in general.
is there an app that disables constant searching? i wish it could be automated...either there is a signal or there isn't, but if there isn't then there is no searching for one. or maybe it searches every half hour, i don't know. right now my only solution is to live with it or turn on airplane mode every time i enter my building and turn off airplane mode every time i leave, which i must admit is a big pain in the arse.
Man, it should be illegal to block cell signals :-\ I get the idea of staying off the phone at work but if something happens to my kids and I have to wait however long to find out I'm gonna blow something up.
I think this phone is extra harsh when searching for a signal.. After a work night my "time without signal" varies from 30ish% to 50ish% and my battery is unforgiving as well.
I really don't think anything can be done other than turning off stuff like data, sync while roaming.
Edit ** just realized I'm in the GS3 and not tho EVO section lol, sorry but some of it still applies

Typically they are blocking all RF signals, and it is a security measure to block "outgoing" signals, but impacts incoming as well, can't really effectively and cheaply do one without the other.
Pretty common for companies looking to protect valuable information. I know of several in the Denver area that do this.
As for the legality, technically your on private property...

my company blocks cell signals for some asinine reason, but the worst part is that there is reception sometimes, so my phone is constantly searching for a signal throughout the day. i'm certain this is causing some unnecessary battery drop, and these days i'm awake and active for 16 hours a day and really want my battery to last that long. it wasn't a problem on previous phones of mine, but this phone uses a lot of battery in general.
is there an app that disables constant searching? i wish it could be automated...either there is a signal or there isn't, but if there isn't then there is no searching for one. or maybe it searches every half hour, i don't know. right now my only solution is to live with it or turn on airplane mode every time i enter my building and turn off airplane mode every time i leave, which i must admit is a big pain in the arse.

Same experience. The cell radio uses 70% of the battery under settings>battery when I'm at work in my faraday cage of an office. Connecting to the local wifi ap doesn't seem to help.

Use Juice Defender it will alow you to set a limit on data searching and molile searching.

so i downloaded it, but it says nothing about disabling mobile searching, just data searching?
I got a weird one for you guys. I had LTE on my nexus 4, but after tethering for awhile, my LED started flashing red and the phone got hot. So I turned off tethering, but my LTE became intermittent, and over the course of the next day, I lost LTE connectivity altogether, even if I set it to LTE only, I wouldn't get any signal. This is what I've tried, changing different hybrid radios, changing ROMs, factory restore to original ROM. The other symptom, and the one I care more about, is that my battery now drains pretty quickly, whereas it would last 3 hours of screen time on before this incident, now it lasts less then an hour. And it seems to drain while the phone screen is off. Anyone have any ideas what it could be? Did I burn out my LTE modem?
I think you need a new battery.

I have a feeling it has something to do with the modem. Day 2 with the damaged phone reveals that my signal will go in and out, sometimes it will be on 3g, sometimes on edge (even in 3g areas). If that's the case, a new battery won't necessarily help.
Now 3g is gone completely. I can only use 2g. Anyone else run into this problem?
I had this problem a few years back. It was the wireless provider who was adjusting my internet speeds. After one simple call they stropped doing this and my phone was always connecting at 3G (I don't have the LTE hack installed)
