Help me understand the poor battery life on Fascinate

I have a work issued iPhone 4 and the fascinate. I fully charged both phones and put them on my desk at 3pm yesterday and did not use them at all. This morning the iPhone was at 98% charge and Fascinate was at 30%... Both phones sync with a exchange account and both have very good signal strength at my home.
I've checked the battery usage on Fascinate and the top 4 items are: Display 49%, Media server 15%, Cell standby 14% and Phone idle 9%. How can standby and idle use so much battery? I also used task manager and killed all running programs yesterday.
So what could be causing this? I can literally watch the battery percentage click down 1% for every couple of minutes of use.
Running Blackhole v1.3 with JT's Stable 11/11 kernel.

After a full day's worth of average use my battery (off the charger at 9am, on the charger at ~1am) My battery rarely drops into the orange.
You mentioned you had a task killer, I'd blame that first and foremost. Also, I think there was something inherently wrong with your test... if a screen that was off used 50% of the battery...
It's also entirely possible that you're just trolling, because I know from roomate experience that his phone if left alone is not at 98% battery after 24 hours. Also, APPLE lists the standby time as up to 300 hours. That would mean that at best you'd be looking at an ~8% drop after 24 hours.

That 15% used by the media server probably didn't help much. What all was your IPhone running in the background...oh wait, nevermind.

I dunno about the iphone but I feel you on the fascinate. I left mine off the charger, no screen on, with airplane mode on, and the battery dropped 50% in 7 hours. With absolutely no use. I'm lucky to get 7 hours during the day actually using the phone. Three display is always around 70% usage of the battery even though I have brights all the way down and always turn off the screen.

I use Ultimate Juice Defender and I take my phone off the charger at 6:30 a.m. and by 5:30 p.m. I am usually at 80-90%.

Not sure, you might just have a bad battery. I have been off the charger for almost 7 hours now (early day). I have been messaging (google talk and sms) had WiFi/BlueTooth/GPS running constantly I rarely turn them off.
Have been using google maps off and on for at least 20-30 minutes as well as voice. And about 45 minutes of phone calls.
For me:
Display 29%
Standby 26%
Idle 16%
android 12%
and then bluetooth, LauncherPro, OS and Google rounding out the remaining quantities.
Oh forgot and a solid 20 minutes of angry birds

i use a task killer but i allways set system apps to ignore except camera and google maps and autokill stuff like file explorer, root explorer, games and stuff.
I get up at 4am use my phone pretty often little of everything and can make it threw a day getting homr at 5pm might be 16-20% battery left but still good imo.
Removing bloat might help?

I went to lunch and played with the phone while waiting for the food. Just red some news and surfed the web a bit. Before lunch the battery was at 34% now its at 16%, I think there definitely is something wrong with my phone. I wonder if a different kernel would help.

Try resetting battery stats and reconditioning the battery. There's no way it should drop more than a handful of percent asleep in airplane mode... Maybe one per hour.

How would I recondition the battery? I've reset the stats with a fresh battery before and have tried different kernels. I have two batteries and it's the same with both. I even took it to verizon but they said there was nothing wrong with it even though it dropped 30% on their test call.

I'd definitely say its just a bad battery. My fascinate stock destroys iphone battery life. With a UV kernal it at least doubles iphone battery life. My work issues iphones so I get a daily comparison.

I would say battery as well, my phone has been off the charger for 20 hours now and I'm at 50%. It's my work phone so its a stock kernel.

I was in your boat. The first fascinate I had would be unplugged at 6:30am and dead at 3pm with very little usage. I hated this phone. I got juice defender and it would last until 6 or 7 with very little usage, and as I used the phone I would watch as the battery rapidly ran dry. I got two other fascinates and it was the same issue. Then I got the one that I have now and it uses almost no power in standby. with juice defender and it being on idle, I can get almost 2 days out of 1 charge. I know it sounds ridiculous to you, with your experiences and it being a smartphone, but samsung has done some kind of magic here. Keep taking your phone back until you get one that uses very little battery on standby. Apparently there are a lot of units with bad batteries. As of this writing, with Ultimate Juice, my phone has been off the charger since 5:30 this morning, did some flashing, which uses the battery open throttle, installed 5 apps, played angry birds for about 35 mins and I am at 91% at 10:09

Well my 30 days are up, verizon found nothing wrong with it and I have 2 batteries.

Try a different big red CSR, and if you fail again, try bricking it in a fixable way after backing up. If you come in with a force close loop, I but they won't have any idea whats going on and you'll have a high likelihood of getting a new phone. If it fails, just reflash and try another tack.

Haha perfect.

I would honestly try one of the Stupidfast kernels if you really want bettery battery life, but honestly it sounds like some kind of hardware problem.
Stupidfast kernels really do give me better battery life. I was skeptical at first but after wiping the battery stats and rebooting after I unplug I've been getting GREAT battery life.
I'm a HEAVY user and I unplugged at 11 AM and 9 hours later I still have 31% left. With ANY other kernel, my phone would be at <20% by now, probably under 10%
I'm a believer, and will be donating come Wednesday when I get paid

Tried them all. But the stupid fast does seem to do the best job.

I will say one thing, with the new DJ05 update my battery life is great. Best I've ever had. So when it is finally pushed to u enjoy. I feel like there has been some tweaks made in the upcoming update that make even a bone stock fascinate one of the best around.

Acceptable Battery life?

I have read many other threads about improving battery life and such but I am still at a loss. My battery in my Epic is only lasting about 5 hours(9AM~1:30PM). I have a moderate signal the whole time and I am using the phone but I only have the screen on about 10% of the time according to Battery Stats(forget where I found this info, maybe spare parts?)
I have turned off Wifi, bluetooth, 4g, GPS only turns on when I open an app that needs it. I really have no idea what I am doing wrong since this seems to be completely terrible battery life. I have also killed the drm service and have found that it did not help my battery life much.
I am rooted and running Syndicate Rom 1.0.2(not froyo since I use a Mac and have not gotten my hands on a pc). I am using Xtreme Kernel clocked at a max of 1ghz.
Any other tips? Should I take the phone to Sprint and ask for a new battery? The phone at this point is only about 3 months old. If this seems to be normal for battery life then I am pretty sure I will be jumping ship and getting a new phone.

Only advise I have is to toggle airplane mode after every boot and switch from the extreme kernel to pheonix 1.43, it has the best battery life by far as will any of the phenix kernels but 1.43 is the best

I got 25 hours of a charge the other day. Had to grab a screen shot real quick before it **** down. Might frame it. On stock dk28 with moderate use, lots of pics...it was on christmas so it was prety well used, trying to escape conversations with in laws.

I'm having the same exact problem. Same ROM and everything. I'm getting absolutely terrible battery life, maybe 5hrs on a full charge. Its ridiculous especially seeing how the nexus s is basically the same phone and gets nearly 20 hrs with no problem. WTF!!!??

Would bet a dollar that your phone is not entering sleep mode properly. Download Spare parts, charge your phone up, unplug it and turn the screen off and wait for like 10-20 minutes and then turn it on and open spare parts and look under Battery History. You will see that it will say Running 100% or something high like that.
This is probably because of something you set up. Either facebook updating every 30 seconds or maybe push email. I dont know.

I pretty much always get at least 24 hours and I work in a basement where I barely get a signal. I leave wifi on all day. I talk for about 20-45 a day on average. I listen to music for a couple hours a day. I play games for a good half hour of my lunch break and sometimes for an hour or two at night. Sometimes I forget to turn my gps off for half the day while I'm in the basement.
I have killed a battery in 6 hours when I spent the entire time downloading and playing games. And I had a battery last 42 hours a couple weeks ago when I was helping a buddy work on a car. We used it to drive some crappy pc speakers for music for about 8 hours in those two days and I spent a couple hours over those two days looking for info to help us diagnose his car.
I have been on Mammon's DK28 for a few weeks and have mostly been on the latest FroYo roms since the leaks starting hitting the public. I ran the same rom and kernel as you guys for a couple weeks, and I don't remember the battery being that bad. IIRC, I was overclocked and still saw 18+ hours of battery life with normal usage.
What are we doing differently? That is the question. Do you have a bunch of widgets and a live wallpaper? I don't. I try to keep my widgets pretty minimal. I have TWC on one screen, a flashlight widget on my main screen, and Pandora and PowerAmp on a third. I generally use a pretty dark wallpaper, too. Something simple and easy on the eyes as well as the amoled. I also keep my wifi on and set it to never sleep wifi. Why? So it doesn't search for a 3g data connection. I have wireless networks I can connect to in the places where I spend most of my time, so I might as well use them. Sure it has to power up the wifi radio, but the wifi radio seems to use very little power when you're sitting somewhere with a good signal. Also, read "How to Train Your Dragon" in the dev section. I have three batteries and generally reset the battery stats on one of them every two weeks. If you only have one battery, every 3-4 weeks is suggested. I always charge my batteries in the charger and almost never plug my phone in (because I don't have to) and about half the time I bump charge the battery after it is finished. Be careful with bump charging as it can reduce the number of charge cycles your battery can take, but can net you 10-15% more capacity in the short term. I rarely discharge my batteries below 15% except for when I'm recalibrating them. If you discharge your battery to too low of a voltage it can reduce capacity. And if voltage is reduced too low, it won't charge at all, but may be fixable with a cadex machine.
Be sure to go find that thread on how to train your dragon. There are some links in there that will teach you a good bit about how lithium ion batteries work and what you can do with them. After that, you need to see what is running on your phone to use that much battery. Is some process or group of process eating your processor?
edit: Look Mom, I wrote a book!

I will try changing kernels and updating to froyo(maybe hijack my dad's netbook).
If this doesn't work then I am going to go to sprint and see if they will swap out my battery. I tried the thing with spare parts and it says time running is 18% since last unplug which seems a bit high but not too ridiculous.
I have read and followed the instructions in how to train your dragon. I am really starting to think it is a faulty battery. I will report back, thank you everyone for the advice.

ok, thank you all for the advice. I am able to get through a whole day now on a charge since changing to Phoenix. Maxes out at about 10 hours as long as I am not constantly on it.
Updating to froyo later today.

Not really going to be helpful for you, but just my observation:
DK28 has MURDERED my battery life. Lots of people have issues with DK28, but the GPS, accelerometer, etc but all that stuff works fine for me - the only problem is the mega hit battery life took.
Let's hope the official release isn't as bad.

DK28 probably murdered your battery life because you forgot to do one of the battery saving techniques that you were using on your previous DI18 rom. Pretty much everyone else is seeing battery improvements with DK28.

I don't think so. I never use GPS, 4G or Wifi and I've always had the brightness auto adjust on.

Insane Battery Life

I'm hitting 41 hours and still have 19% battery life. I noticed it took around 10 full charges before my phone started to get this great battery life. I've been using it as normal and even listened to howard stern for a couple of hours yesterday. Talked on the phone a bunch of times around 30 texts and even used my 4g for a few minutes. I've never had an andorid phone last this long for me even when I had my Optimus S which I thought was awesome.
Anyone else getting this awesome battery life? I'll post screen shots when its about dead as I dont want to plug the phone into usb to get the pics.

I would investigate as that shouldnt be. My shift lasts almost 2.5x my hero. I bet if I had your phone in front of my I could find out whats killing it soo fast.
Is your phone getting hot? I would do a full system wipe and start over from scratch and see if it doesnt get better after you try the things I've listed below. Note, I didnt have this great of battery life until 6 days after I purchased the phone and charged and discharged numerous times. The first few days the battery life was not good at all.
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 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.
Remember you can get china made batteries for very cheap. I paid $12 for 2 batteries and a wall charger off ebay. This phone uses the same batteries as the Hero and Evo by the way.

I noticed Yahoo mail and Craigs list apps I downloaded from the market have a memory/cpu leak that kills your phone super fast.

I find that Battery indicator doesnt draw much power if any as I've always used it and never had a problem. The maker of the app states it uses no extra power. I love the circular battery indicator version found in the market. Its not a widget, it stays in the upper left corner of your notification bar. You should give it a try.

Phone doesn't get hot. I've started from scratch twice, I've ##DATA# reset. I had terrible service and data speeds before I did that and it did a number on my battery. Now it'd fine, but it just drains while doing nothing.
I never use task killers or auto sync, I live with spare parts and and monitor it, no real partial wake usage to speak of. I know how to save battery, my hero get 20+ hours with use and auto-sync on.
I'm thinking my battery might be bad. Feels like your talking down to me too, captain.
Sent from my bathroom, with toilet paper.

I haven't had mine a week yet, but atm I'm not getting half the battery life I did outta my Hero running AOSP's Gingerbread alpha.
I'm blaming the crap bloat that's part of the stock ROM.
With the display set to 15-20% I've got the display accounting for 69% of the battery usage. :/
Turning off sync is not an option and I feel defeats the purpose of a smart phone. Additionally, I fail to see the point in paying for 4G and not using it. (I do turn it off if I'm out of area for it or don't expect to be using much data.)
So thus far I'm disappointed in the battery life... but still think it'll improve vastly once rooted and cleaned up.
EDIT: Just did a test running Angry Birds for about 10 minutes... maybe 15. It ate up 9% of the battery in that time. Added another 1% to the display usage.

so far this thing is a golden brick to me

Just out of curiosity, how do you calibrate the battery? Just in case my battery life doesn't match the reports (I know my luck )

getting great battery life isn't that surprising given you've got a 1500mah battery much like the evo and epic however 48 hours is rather impressive.

Battery, it's now time to exchange you!

I'm so giddy right now. I've ordered an OEM battery for my Vibrant, and i should be getting it any day now. The reason for me ordering a new battery is limited usage time. Lately when flashing any ROM, I make sure It is at 100% charged. I will normally get about 4.5 or less hours of usage - using a little app named 'Battery Left'.
I don't use a task killer. Ever. I know this has some controversy signed to this, but the Android OS is engineered without issue regarding this.
I Use WiFi whenever I can (uses a fraction of the power 3G radios use). When I CAN'T use WiFi, I make sure it's turned off so it's not wasting power scanning for hotspots.
I make sure GPS is off whenever i'm not using it.
I set display timeout to 30 seconds, set brightness to Auto, or manual and the lowest. Little trick, if Brightness is on manual, you can adjust it on the fly by swiping left or right across the task bar.
I let the battery TOTALLY discharge at least once (twice is better) and then charge to full. This doesn't condition the battery, this just calibrates the battery metering software, so that it knows for sure where zero is, making the metering more accurate.
I try to use a darker colored wallpaper, blacks and reds and deep greens and blues use less power than lighter tones, and white is the worst.
I get a half-day out of my rooted Vibrant on T-Mobile, and I actually use it as a phone (amazing huh?), PDA, game machine, ebook reader, etc, it's not just in my pocket on standby. Battery life has nothing to do with it being unlocked/rooted.
I understand the biggest reason why people think THEIR particular smartphone has some sort of battery problem: They just got it, and are using the hell out of it. We tend to not set it down in the first few days/weeks, we're always fiddling with it, showing it to our friends and co-workers, etc. Once the new and shiny wears off, and we settle into more "normal" usage patterns, we start noticing that we get a lot more battery life out of the device. Some people think that the battery is now "broken in", but the truth is, the USER is broken in.
Some of my POWER hungry apps I use on a daily basis is 'SportsTracker' which I use riding my bicycle to and from work (7.3 miles one way). SportsTrack uses my GPS and tracks my ride in REAL time. It sends a link to Facebook and Twitter, where my friends, and family can watch me go. This app uses about 17% of my battery - one way. So, at the end of the day, just using SportsTracker it uses at least 35% of my battery.
Speaking to the heavy users, how many hours do you normally get using your Vibrant?

With 20-30 calls a day, 20-50 texts, dozen or so emails and listening to music and just geeking on the phone Axura 30 hrs before it is 15% Trigger 24 hrs before 15%, but then, that's how it works for me. Since I got rid of stock roms, I have had ZERO battery problems, I only use Task manager. Deleted all the bloat and I have screen set to 50%. Battery is no longer an issue

With Bionyx 1.3 I let the phone sit idle (exchange email running in the background though) from 8AM and till 4PM it took only 15%
Skype+music+movie for around 1 hours and it's down 15% more (now 70%)
I guess it'll last 1.5 day normal use and 2 days idle use

That's a great battery life. My bionix eats more battery on almost the same usage. I have around 76 user apps installed and some bloater. One thing I have noticed using system panel is when I sleep, my phone sleeps with me and uses an average of 1% battery per hour. Is that good? I still I think im not getting optimal battery life when im actually using the phone.
Sent from my Samsung Vibrant (Bionix-V 1.2.1) using XDA Premium app

You guys think that's good battery life? Nah, this is good battery life.

I always got 20-30hours a charge with most of the Bionix roms. However with Bionox 1.3 I struggle to get more than 12 hours with the same usage. I did notice that new app BLN (using your soft keys as notifications) was reported on some other roms as a battery drainer, so I have uninstalled via Titanium. I will report back tomorrow if that is the issue. I still use KA5 modem, so that part has always been a constant

Weird. I'm on 1.3 as well. I'm 15 hours into my charge with normal usage on 3G/WiFi and I've got 25% left.

I'm 15hrs in running Bionix-v 1.2 and i have 42% left. That's with GPS on all day....phone in pocket from unplugging to about 3:30pm. Then only light use.
Days that I use heavily I'll have to plug in around 4pm. I'm not too happy with my battery life. I love my phone...but my old iPhone 3G had top notch battery life! lasting 3 days without charging.
Is it not weird how these times fluctuate so much between users?
Will the new Galaxy S 4G battery fit in our phones? Or will it even be worth it?

Do you have the superpower app? It saves my battery big time when phone is sleeping.

I ordered a batter charger, two spare regular batteries and one spare extended battery last month for my vibrant.
Now I keep a spare charged battery in my pocket and I no longer have to plug my phone in anywhere I go. I just swap batteries and put the dead one on the charger when I get back home.
If I am going to be away from home for more than 24 hours then I put in the extended battery which gives me about 2 days worth of use.
Its a bit of a pain to have to be down for a minute when the battery is dying, but I am more content using the phone this way since I can now keep it with me instead of leaving it upstairs or on my office desk to charge.

My phone is on the stock KA6 kies and from 8-8:30 it is off the charger on 3G. When I get to work it is on WIFI with WIFI Calling(no signal indoors) from 8:30-12:00 and goes back on 3G. then at 12:30 it goes back on WIFI(calling) and sits like that till 5:00. Usage during that time, some email viewing, 10 txt or so, 5 min phone calls and that is it!! from full charge at 8am to 5 pm I'll be at 45-50% battery left and what you read above is all I do with it all day. Battery life is horrible. Not much I can do(unless someone has an idea to fix the issue) as I need WIFI calling otherwise why have a cell phone?

Food for thought

So 16 hours with 3G and WiFi Calling on all the time...on the STOCK Samsung crap? Thats pretty awesome man. WiFi calling is a HUGE drain. Spend the $2 on an app called SystemPanel. It will tell you exactly what is taking up CPU Cycles which, of course, uses battery.
I go 24 hours on a charge with routine use. Granted, everyone's use is different. But I got two days with the KA7 modem on Bionix V. I see no difference with 1.3 (haven't used it enough to tell). Granted, I had WiFi Calling frozen and was on EDGE most of the time and turned on WiFi when I needed it. I've observed WiFi Calling using excessive CPU cycles when it isn't even on. Its pretty poorly coded. I recommend freezing wifi calling when you aren't using it.

I wouldn't suspect the ROM, but rather battery, charger, cable, port... store can check those things out for you.
In re to what you can do in theory, modern ROMs/android OS handle things pretty efficiently so I don't think it is something you have done - that is if you are not overclocking and leaving it on your oven when cooking.

Make sure you are at like 3 percent before recharge. Do that a couple times and out will restore your battery, worked for me

Wow I hope your battery worked itself out in the end. I just have another question. How long should a stock MyTouch 4G battery last?
Even before I rooted my phone and tried a bevy of roms known for their battery life, but I never get passed just about 9 hours. I used my phone moderately text messaging, surfing periodically and playing music and podcasts in between classes. I have turned off auto sync and did the battery stats wipe.
Just wondering if my expectations are too high. Nine hours is nice, it gets me through the day but then I lose it for a couple of hours in the afternoon to charge up for the remainder of the day.
Thanks again guys!

Try TDJ's CM 7.2 kang. I have gotten over 24 hours on that ROM.

Battery life is like fuel mileage. Its how you drive it. One person may get 17 mpg on a car that someone else gets 22 in. Screen on time is better to go by. A good ROM/kernel combo will get you around 4 hours screen on time. Maybe more.
