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.

[Q] Absolute Best battery?

What rom (stock sense look) has the best battery overall. I rooted my moms evo to get her a great battery life but it still seems to be dying really quickly. I am using 4.3.1 kernel. She's only getting around 6-10 hours of battery before she has to charge it. I had the evo before and could get a full day and a half before charging it. I can't remember my setup since I switched to the evo shift. Any suggestions would be greatly appreciated, thanks.

im using the cm7 rc 2 whatever kernal is package there is PHENOMINAL im at 60% @ about 12hr..... Moderate use between wifi and 3g

That's the best you're gonna get with NORMAL usage and a REGULAR battery. All those users that say they get like a day or two are full of it. They get that long because their phones are sleeping most the time. I've used EVERY rom/kernel combo out there and the best I ever got was about 15 hours. I literally use my phone all day while at work from browsing, texting, calls, facebook ,twitter, and games. There should be a definition for moderate. I consider myself a heavy user; unplug at 7am and my phone last until about 6pm with about 20% left. Its not going get any better than that for a moderate to heavy user. From sense to aosp with the stock battery I just never achieved better results but I'm pretty happy since I get to work at 8am and get off at 5, buy 7pm its nearly dead and I just plug it up. You should invest in an extended battery imo.

I agree to a point. I mean, it all depends on usage. I can believe someone with light-moderate use can easily get a full day with the right setup. I do it now with CM/Savage, but I'm definitely not a heavy user.
I do see some people make wild claims of 2-4 days without a charge.. and I think it's possible IF you don't use your phone or you turn everything that makes it a smartphone off. Which is pointless IMO.
Nobody can really give you the perfect setup because every EVO seems to behave differently. We can only make suggestions. Make sure your mom s awareof all the things that can drain battery (push notification, updating widgets, weather updates etc etc). I would then research a good sense rom/kernel because CM7 is a definite WIP with different issues for different users, it may turn her off.
Maybe check out MikFroyo or Myns rom. I hear a lot about how good they are.

+1, its just crazy I see people throwing crazy hours out there lol. I think if your phone is sleeping 75% if the time then you shouldn't even talk about your results since that doesn't fit into the norm for usage. Most people check their phone like every 10 mins(don't quote me) I know I do lol. People throw around like 36 hours and even longer its insane to me.

Sent from my PC36100 using XDA Premium App

I don't know about not being able to get more than a day of battery life and use your phone. Using MIUI with a Savaged-Zen kernel I was able to go almost 2 days without even plugging it in once (I'm specifying this, because I've seen screenshots where people claim crazy battery life, but the graph clearly shows that the phone was plugged in and charging several times throughout that time period), and my display usage was still 44% of my battery. That was still minimal usage for me. I posted the screenshot in the MIUI thread if you care enough to check.
I do mostly agree, though. Most people posting outrageous battery life have display percentages around 5-10%, clearly never removing the phone from their pockets.
Anyway, as for the OP, the biggest missing variable is that we don't know at what percent your mom considers it necessary to charge her phone. If she plugs it in around 50% to be sure she can make it through the day, that means she could have gotten another 5-8 hours of battery life (assuming she's not draining it down to 0%). This fact could make the difference between bad battery life and a paranoid mother.

Try the ava froyo z3 I love it best rom I've used so far so guess I'm sticking with it o and get her juice defender with ultimate juice and lock it down so it kills anything she's not using

I agree with most of you people. Initially went to FreshEvo by Flipz when I rooted and battery life did not change much from when I was running stock. I have since switched to CM7 and battery life is significantly improved. Now getting 12 hours on a single charge with moderate use. I always turn 4G and wifi antenna off when not performing any data-intensive use. But I refuse to kill my 3G data connection when my phone is in my bag or desk while at work. Reality is that it IS a smart phone and killing the data to save battery life defeats the smart phone bit, no email no Facebook syncing no MMS etc. The only time I kill 3G is when I am in the mountains skiing.
My problem is that I work a 12 hour shift so 12 hours of bat life is not ideal. I have invested in an extra charger but would obviously be happy to not use this. I have heard lots of testimony that the savaged Zen kernals show some promise in improving bat life. When CM7 final drops I plan on flashing one of these kernals with the new ROM on wipe. I will stay away from the SBC version though for fear of improving battery charging but having my phone melt down or pop on the night stand next to me while I sleep... or worse in my pocket!
I will report back if I get any significant results.

what does this do?
I used this before and I found it was pretty inconvenient with wifi/3g and always having to wait for these to get turned on or turning them on myself.
I did see 11-13 hour battery with my normal use (light surfing, 1-2 hours calling, many many text)...but then I removed it and I have everything pop up when I click on it and I am getting 9-10 hour battery life.
I am not normally a battery hog...but I REALLY like it when something I click on WORKS then and there...without a no connection message.
I am more than willing to lose the extra battery time for the convenience....maybe if I start using more battery intense stuff Ill revisit this app but for now...I like things to work when I expect them too...

I prefer to use SetCPU to lower the CPU speeds when it's off, and when the battery reaches 25%. Works great for me. I used JuiceDefender, but I just had nothing but problems with it.

I get over 24 hours of battery easily with moderate use (meaning a few games, a lot of text messaging, some web browsing and at least 2 hours of music).
Last charge lasted from 3 pm one day to 6 pm the next day at 20% battery when I plugged it in again.

All batteries aren't equal

I always wondered why some SGS3 users seemed to have great battery life and others didn't then I found out why for myself. I had my S3 for maybe 5 days then managed to crack the screen from a short fall (the screen is really too delicate) so had it replaced through my insurance. I returned the broken device but kept the accessories including the battery of which I now have two...yeah! The battery from the replacement device always drained entirely too much on standby time and gave me roughly 12 hours on moderate use. The original battery routinely gave me 17+ hours on moderate and had exceptional standby time. I subsequently returned to using my original battery and enjoying great battery life on my replacement phone.

ya i'm with you there cause a lot of people complain about battery life but mine seems to be great yes i can drop my phone from 80-60% in 2 to 3 hours but thats extremely heavy use where if i don't use my phone at all i find i will go through about 20% of the battery for the full day and that is with light use as well

Mainly due to signal if your in an area where your signal is bad, your phone constantly polling for signal if you use WiFi the whole time then yes you would get long battery life. That's why I don't trust any screen shot in "post your battery life" with WiFi signal. I use my phone as it comes with my plan, I don't constantly seek out WiFi spot to hook up to. It's dangerous for security reason and defeat the whole purpose of owning smart phone with data plan. If you can't afford a data plan than don't get a smart phone.

Juice defender kills batteries more than it helps I strongly recommend you stop using it.

Proof of battery life
Approximately 30 mins of call time and 2 hours of talk time... 44 hours later my phone was about ready to die! Clearly this was light to moderate use but this gives me great hope that I should be able to last more than the 12 hours I was getting on my other battery with moderate usage. I credit the longevity to the use of CPU tuner, Juice Defender, the build in power saving mode (everything checked except CPU), and applying the cell standby tweak (though its utility is debatable).

To all those with lousy battery times!

I have a year old Note and have been getting progressively lower battery times, I have tried every possible trick and several ROMS. Recently was getting as low as 12hrs. I have had a cheap replacement battery (non Samsung) which was not used often. Recently when I used it I noticed about the same battery life as the original. I purchased a new Samsung battery and now I am getting over 40hrs on one charge with moderate use and sync on with no other changes.
My messge is : change your battery at least every 8-10 months, you will be astonished as I was. One of the great features of the Note is the ease of change of battery, use it!

Yep same for new battery and it's like I have a new phone. Without changing anything my screen on time almost double.

Non removable battery is a deal breaker - your phone will be useless after 12-24 months depending on the charge cycle.

i don't have the time to order a new battery online or look for it in stores so simply i swap out the kernel for the rom i'm using and with the current one i get about 20hrs which isn't much compared to when i got it a couple months ago and worse yet if you have on hsdpa+ whole day battery life drops to about 2/3

After one year (for me ten months) the note 1 needs a new battery. Decreasing bat life, random restarts, and screen flickering are all indicators. I thought i had runaway process issue or hardware problem. But i finally ordered an ankor battery from Amazon and my unit is fine andback to 20hrs.
I thought this was settled back in Nov.
Now just waiting for my jb!

I have a year old Note and have been getting progressively lower battery times, I have tried every possible trick and several ROMS. Recently was getting as low as 12hrs. I have had a cheap replacement battery (non Samsung) which was not used often. Recently when I used it I noticed about the same battery life as the original. I purchased a new Samsung battery and now I am getting over 40hrs on one charge with moderate use and sync on with no other changes.
My messge is : change your battery at least every 8-10 months, you will be astonished as I was. One of the great features of the Note is the ease of change of battery, use it!

Do not buy a spare the time time as the phone if you are not going to use it until the original goes as it will deteriorate from the day it's made, even with out use.
From box 13......

I don't know if this is still necessary nowadays, but I always use the battery till it's about to turn off the phone. My batteries always have a pretty good lifetime, so I imagine that helps.

My 10 month old stock battery is still giving me much more on screen time with wifi. This is reduced to half. I used to get 10-12 hours on screen time when i got it out of the box.

10-12 hours of screen on time with a single charge and one battery (2500 mAh) ?

In his dreams I have 2,5 hours screen on time with autobrightness. That was much better on gingerbread days. Maybe leaked Jb versions are not well optimized. We will see after official update. I think I will buy an original battery too.

This is a common misconception that if you leave the battery to almost deplete every time it will be better for it in he long run. I have done a lot of research on this topic for laptops and smartphones. Essentially they use the same type of battery technology which does not suffer from memory effect, but if you stress the battery a lot (letting it deplete before you charge it again or almost deplete below 5%) than it will damage it more quickly.
The optimal way of charging your battery is:
1) After the first cycles just charge it whenever you want (even it is at 70% and you are at work, you can plug it to get another 10% and then unplug and use)
2) Don't let it deplete, it will stress the battery too much and damage it in the long run
3) Every 30 cycles, you can let it discharge to below 5% and let it recharge until 100%
I have done this on my PC which still has its battery at above 80% after almost 3 years, and to some extent on my Note, but as I can't always foresee how things will play out I sometimes need to use to until the last drop of energy .
Hope this info helps.

10-12 hours with stock rom and stock battery. Now it has dropped to 7-8 hours. With no replacement. I will be getting another battery soon.

Wonderful.
You are getting 7-8 hours of 'screen on time' with a one year old degraded battery. When you get a new one; lemme know, I would like you buy the old one of yours.

That is definitely battery drain. Better post a screen of the battery your apps are using...

With a brand new battery, you cannot achieve much more than 5 hours of screen on time with general usage.
You can indeed get much more than that when watching video, but that is the only scenario where that is possible (or maybe staring at a black picture for hours).
So people saying that they get 10 to 12 hours of screen on time are really getting 10 to 12 hours of uptime, meaning the phone is turned on but is sleeping most of the time, with maybe 2 to 3 hours of screen on time.
That's lousy battery life, and those people should buy a new battery.
