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.
Sent from my Voodoo-powered Fascinate with XDA

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.

Lol we need more than that to help.... what post?
I get anywhere from 10-16 hours on Macnut 13 with JK6, depending on usage

4 hours with what?
Sent from my SGH-T959 using XDA App

I get great battery life with jk6. 5 hours idle and didn't drop even one percent, but it drains fast if I use wifi.

What if you delete MediaHub and DRMua?
I seem to get much better battery without those.
I also enable WIFI during sleep... it's in the advanced settings under wifi.
And of course I remove all of the other bloat apps.

JK6 with all the crap removed and I average 18-24 hours with moderate use. The lowest I've seen is 12 hours and I had the screen on for almost 7 of those.
Looking forward to when we get source code and can run an undervolted kernel.

I get really great battery with JK6. I suggest you to do battery conditioning.

JK6 has great idle battery life for me but as soon as i start to use the phone for low activities it drain faster. By "low activities" i mean as in making call, use map, navigation, changing settings.....
Here is my usage report:
3h since unplugged from over night charge
73% left
Display on for 45m 19s (lowest setting w/ auto brightness turn off)
Voice call 45m 21s
Cell standby 3h
Phone idle 2h 15m
To me this was worst than when i was running JI6. Also i lost 3G every now and then in the same area that i travel everyday.

Using maps and navigation are some of the most power-consuming tasks you can do with this phone. Navigation in particular killed my Vibrant dead in a few hours.

The kswap process eats a upon of battery when in use on the jk2 roms. I thought jk6 had this fixed, but it may just be better on the custom roms. I get great battery life on my jk6 rom.

I had similar battery life using various custom kernels. Installed Aux. 2.1 with stock. With heavy use I am running around 8 hours. Normal use around 12-16. Those other kernels will eat your battery alive. Try a stock kernel. Conditioning doesn't do crap.

noticed this also, doesn't really make a difference to me.

Most of these problems are user error. I woke up today with around 70% this mourning at 7am. Its 12 hrs later and im at 42%.
My Day:
combined 45min of calls
atleast 30 txt message
Ton of emails and they sync all day
Started my music player at 9 and didnt pause until 5pm. playing out of speaker
Browse the internet off and on all day
downloaded a 100mb mixtape torrent through 3g
screen brightness at about 60%
Probably a couple other things but app called Battery Left is telling me I have 10hrs left.
I really suggest running all stock. I need no lagfix/special kernal or anything with the newest leaked samsung firmware. Havent had a single issue since I switched to this rom.

I'm sorry, but I have a very hard time believing that, ALL THAT, only took 28% battery.

17%after a couple more torrents. Not wirth trying to prove but the stock rom made my extended battery worthless besides special occasions.

Thanks for the help. My battery died after four hours as expected. Plugged in and reconditioned and let it charge till it was full. Now It's been about five hours unplugged and I'm down to ninety six percent.
However as some of you have posted my battery drains VERY fast once I use it sparsely. It dropped almost 5 percent after a few mins of browsing the market. Weird. But whatever standby is amazing.

What kind of battery life are you seeing?

Just recently got an Incredible. Using the HTC extended battery (2150 mAh) and I'm still only seeing ~14 hours of battery life. Also currently using CM7.
What is everyone else seeing?

I'm using the Redemtion Rom 2.2 with Incredikernel 12/21, and with the stock battery I can easily get over 20+ hours out of it. I'm also always on my phone. What kernel are you running? That might be your problem.

I'm using an 1800 battery and regularly kill my battery in half that time. I'm actually happy if I get 7 hours out of it. Since you have the 2150 battery pick up a wall charger for the stock battery and carry that on you too.

I'm with you on this. Although I send around 1000 texts a day use the phone probably an hour tops and use the internet a good bit. I call this average usage some call it insane so maybe some peoples average usage is barely talking it.

Well,
I was on the stock 2.2 OTA and I was doing ok. it was better than 1.1.
However I've recently been running 2.3 (http://forum.xda-developers.com/showthread.php?t=865331) and my battery life has improved a little bit.

I'm running virtuous 3.2 and usually after a the day I usually get home with about 60% with pretty light usage.

With very light usage (listening to audible books via audible.com app for about 6-8hrs, 5-10mins of phone calls, limited internet) with the 2150 battery and Lou's #4 kernel I got 52hrs from charger to 14%. That is definitely not the norm, but I thought it was pretty cool =p.
Normal moderate to heavy usage I get 24ish hours from charger to 10-15%.

Na up where I live everyone gets the $5 or $10 Verizon o ly prepaid texting plan. So that's the only way we talk.

Uh 1000 texts a day. Lets say you get 5 hours of sleep. That's 19 waking hours. Thats like one text message sent every minute for 19 hours. Not to mention received. i hope you're exaggerating hahah
I use mine kind of heavily with texting maybe a couple hundred total per day. 2-3 hours screen on total, maybe 15 minutes of talk time. I get 19 hours according to Battery Left. Running CM7

I'm averaging. Quite honestly there are many times where I don't get a break to actually put my phone down for like an hour or so at a time. But I judge the thousand a day based on me resetting my handcent set counter and two weeks later iI was at just over 15000 sent.

Sure, I am playing around with CM 7 nightlies at the moment, but I'll switch back to my old set up and see if I cant get a ss of a number close to that for you.
As I said though, it was very light usage for a few days.

I was running CM6 with invisiblek #18 and getting over 18 hours on the stock battery with pretty consistent use

Using SR 3.5 rom and chad's latest incredikernel.
With mostly having the screen off (no more than 45 min on) it lasted 48+ hours with 22% to spare - note that is not my normal usage, just a test.
Normal usage for me is:
Solid 5-6+ hours of screen on, and it'll last a good 23 hours (as of last night, long day lol) -- Most of the time after a full day I'll plug it in with 40%+ left.
Daily usage also includes
- 45mins of GPS usage
- 2-4 hours of Pandora streaming
- ~50 txts
- ~20 minutes of phone calls
- Youtube for ~45 mins
- E-mail / web ~ an hour
- 20 minute of games
I practically live on my phone but usually make it to the end of the day with 40+% left, depending on the day may be less- but I've never gotten the notification since the Kernel and ROM change.
Overclocking above the standard 998 will drain your battery pretty quickly, more than most other things you're doing. I noticed this and also noticed that overclocking didn't do much for me because 998 was smooth for every game I was playing.
Using HTC extended battery also and I do not bump charge, see:
http://forum.xda-developers.com/showthread.php?t=871051

I just find that hard to believe. If i stream pandora for an hour with a full charge it will drain my battery down about 20% thats using lou's #8 kernel and his redemption 2.3 rom. Thats with a 3500 seidio battery after a wall charge not a plugged in charge.
Not doubting you one bit but damn thats alot of tasking on a stock extended battery too end the day with 40% left.

Comparing gingerbread battery life...

I wanted to start a new thread comparing which GB roms have the best battery life....

I'm running CM7 and battery life isn't that great.
Sent from my SGH-T959 using XDA App

^THANKS^^ battery life on Simply honey 3.8 was pretty good....

This thread is a great idea, but let's put some numbers down rather then, "I get really good battery life!"
CM7: I get about 13 - 15 hours with minimal use on edge network.
Minimal use for me is about 2 or 3 phone calls about 30 seconds to a minute each. Less then ten text messages, very little to no web surfing. Check weather, look at news headlines.

Well, i have only tried CM7 and MIUI, wich is CM7 based, and to be honest, battery life is the reason that i came back to Froyo...just terrible batery life...i can't be charging my phone every 5-6 hours. On Froyo im using Super DragonModz on Project V, and i havent charged my phone in two days, and still its @ 25%...average/min use. Until GB gets good battery life, i might not be using another GB rom as a daily driver...

My battery just went down 2% on a 40 second phone call with my lady. Simply honey. It drains bad. This is my 4th cycle.

Blitzkrieg 18 to 20hrs moderate use 3-4 hrs screen time one.
Pretty good if u ask me.
Screenie attached 30% batt left. Calibrated two days ago.

With every type of battery caliberation it takes a few cycles of charges for it to actually work. I use sgs tools and apply script and that deletes battery bin files. But doing that is not gonna take effect right away i hope u guys know that.
Im on cm7 and my battery usage is better then i expected. With me using either google music or Audio galaxy streaming for a 8 hour workshift and texting and websurfing during a lunchbreak and when that shift is done i still have about 20-to 30 % left sometimes as high as 40% But if im not streaming music and just doing normal things like playing cut the rope and web surfing and emailing, texing etc i can go on all day with out a charge. So maybe u guys have a bad battery???

On Revolution Rom, I can get 16-17 hours of heavy use, which is flashing a new build almost every hour, going crazy on the battery life testing. But people have reported about 24 hours of battery with moderate use.

Asgard 3.0 and 3.1 Both are giving me 13-15 hours with moderate use gaming (my kid 45min-1 hour) internet use, tweeting, email and moderate to heavy phone use (20-40 calls per day) and 1 hour of tunein radio.

I got an average of 15 hours on Blitzkreig with 15-20 short (under 3 minute ) calls, 35-40 texts and an hour or so surfing.... plus a little gaming. I am at 5 hours on Asgard 3.1 and 78% battery.

I am running the Revolution Rom RC1 also and I'm getting about the same battery life. It's about the best that I have gotten on my phone, Bionix Final 2.1 aside. Great job, keep up the good work Ali.

Revolution ROM's battery life is pretty good.
Can't compare with others since I've just started flashing GB roms now (I had tried MIUI before but back then the battery sucked so much it doesnt even count)

thanks for starting this thread, it was just what i was looking for.
i used CM7 awhile ago and the battery life was pretty terrible so i switched back to froyo. so now i was looking around again for reports of battery life now after a couple months of waiting, and looks like its still pretty bad. i guess im still sticking with froyo.
but hey i still appreciate all the work the devs do to bring GB to the vibrant

with all the MINIMUM use or HEAVY use
can you guys post the screen on time with it to shows how heavy/ minimum you use....

I've been using Blitzkrieg for a week or so and at first it seemed really good but the last few days it has been draining fast for some reason. I also have had it reboot a couple of times while on the phone the last 2 days. I'm not sure if it's related....

[Q] How is the battery performance?

Hi,
I'm switching from Note 1 to Nexus 4 which should arrive this week. I wonder what the battery performance is like for an average user, does it last alteast a day (10hrs plus) with moderate usage?
Also, I heard glass back issues, does it really needs to be cared for a lot?

I just switched from the note 1 also to the nexus 4. Have had this phone for almost 2 weeks now. Battery life is a lot better than the note. I'm almost always on WiFi. I'm getting about 13+ hours out of the battery. I flashed the Franco kernel and noticed a slight improvement also. Deff a lot better battery life than the note

Right now I'm using the CM nightlities and franco r71 kernel and my battery is pretty good. It easily lasts a day, right now it has about 50% battery with about 10 hours on and 1hr 40min screen time on. I've uploaded a picture of my battery with one of the older nightlies. But some people have really good battery life and others aren't as good, it just depends if you get a lucky phone.

Battery live has been great for me. Easily over 3:30 on-screen time, sometimes 4:00, and less often I hit 4:30. At the end of the day and I usually still have some juice left. I use FrankenKernel and Trinity Four.

I can get at least four hours screen on time, sometimes over five, depending on other factors such as signal strength and whether I'm on WiFi or mobile networks.
Just been playing with it for the last hour and this is what it's looking like ... 84‰ battery remaining with one hour eleven minutes of screen time. Connection via mobile networks is usually more taxing though.

Stock I could go ~12hrs with moderate use and ~18hrs with light use.
With franco kernel r72, I get 2days with light usage (1.5hrs screen on, 1.5hrs call time, auto brightness, wifi on, bt on, gps on, location services on, push for gmail/plume) and a day with moderate use (same as previous with 3-4hrs of pandora streaming and 1hr of video.)

I can reach 2 hours of screen time when entirely on HSDPA or nearly 4 hours entirely on Wifi with stock kernel until the battery hits 25% mark.
With franco or harsh kernel I can reach 2 hours 30 minutes on HSDPA and 4 hours on Wifi until the battery hits 25% mark.
I send a lot of Whatsapp messages and browsing, not much phone call though. I don't measure battery life by phone up time because most of the time it's screen on time that matters.

Battery life seems great for me
