15 minutes of voice call eats 16% battery =/

I keep hearing some people claim how "great" their Vibrant's battery is. I am on my third Vibrant and battery life has been terrible on all of them. Just recently I noticed ~16% of my battery got drained for ~15 minute voice call. (The attached screenshot shows voice call using 27% but at that time my battery was at around 39%, which means the 15 mins took about ~16% total battery.) I just passed my 14-days buyer's remorse, so exchanging it (unless I want a "like new" one) or returning it are not an option. Any suggestions on how to improve battery life? I already keep the brightness on the screen to the lowest it gets.
Thanks!

Hmm that defintely is not normal. I would check with the store in getting another replacement. 15% drain on 15 min call is not normal for any phone.

There is a bug where if you power down the phone while it's charging, then the reported battery % is higher than actual. Perhaps the seemingly fast drain is a result of the reported value "catching up" to the actual level.

Edit: So I figured out where you're getting your numbers .
Still doesn't seem right though, did you notice the battery percentage before the call by any chance?

My rooted G1 had that same bug. Start charging it, power it down, power up and from completely dead it would show around. 24% in a couple minutes of charging. This phone I've noticed does it as well as newer blackberry's. Bizarre...
What I would suggest is draining the battery till it dies, charge it back up fully and see if you can have it happen again. Could've been a fluke.

looks like a bad battery reading to me.
Complete charge, complete discharge, and complete charge should reset it.

Yeah the percentages do need to be calibrated and sometimes they are off a bit, say 100%-90% actually often goes faster than 80%-70%.
The batteries are also partly responsible since discharge Ah is not a completely linear relationship with voltage (which is why the percentages need calibration).
I would say unless you have a rogue application on your phone eating battery it is more likely just how it is being reported.

So if battery A has x% greater mAh than battery B it does not mean A has x% greater battery life?

I'm having same issue. Battery life on my Vibrant is just horrible. I can barely go half a day until it's fully discharged and that's about 30 min talk time an hr maybe browsing apps and internet and a little WIFI/BT. Just for example I charged it after complete discharge and took it out at 11.30 pm last night, drove my brother to the airport and back around 1.30 and while it was sitting in the car and a few calls I made, it already went down to 74%, I purposely left it without charge till morning.... at 8am it was showing 47%... WTF!!
I have rooted the phone with update.zip, I have installed ATK and have Crazy settings on it.... one thing I don't get is that after it kills apps, they keep coming back every few seconds. Also brightness is at the lowest and no live wallpaper...
UltimateJuice by the way is showing 1.58 times, which is BS... right now it's 10.30AM and its down to 38%....
Any help would be appreciated!

Try not using atk

Vibrant's battery life does suck, even with the supposedly power efficient processor and super amoled!!!!!!
Samsung has some more work to do. Hopefully, the froyo update can alleviate the problem!!!

Anytime the screen is on its eating battery. We have the best screen in the market. If you really want a conservative wallpaper use something almost all black or solid black. When a AMOLED screen is displaying black the LEDs are off.
For those "apps that keep showing up" those are due services that are running in the background. If you don't use the app often set the notifications to a lower time or set it to update manually.
If you've rooted there is a thread on "how to keep your phone quick and snappy" read it. Also fix your permissions through recovery. Rogue apps apps can drain battery.
after 3hrs of on & off hard using (minus extra long phone calls >45mins) I can pull 12-16 hours easily on one charge.
Look into things like eugenes vibrant 6 & JACs UV(under volted) kernel.
GL and car chargers are awesome!
Vibe the XDApp

Battery life on my Vibrant has been superb. You might need to change settings or something. This screen shot was for today with lots of calls and market shopping and I even watched a movie. I do not use a killer, yes I'm rooted with lots of tweaks to my notification bar. I'm using the spiritbomb lwp and its been great.

Unfortunately, the battery life on the Vibrant just sucks, compared to the iPhone.
I came to a Galaxy S and a Vibrant form the iPhone 3Gs.
With the same style of usage, the iPhone lasts at least 40% longer than the Galaxy/Vibrant.
I like the phone a lot, but am really unhappy to have to constantly think about how I use it, to avoid it dying on me before the end of the day.
Basically, with moderate use, it will last for a day, but if I go out after work and do a little texting or take a few pictures, it will die before I get home.
12-14 hours is really not good, since with my old iPhone I used to be able to last almost two full days without recharging.
Plus, the blocking of the camera at 15% of battery life is a truly idiotic decision by Samsung.

Thanks for your feedback! I am newbie in the Android world, as I come from the Apple planet. It just takes time to get used to it.
As for XDA App, where can I get it?

I am looking into the mod for the notification bar, specifically the battery. I have seen a circle battery with percentage, where do I get one?

XDA is your Friend
Search XDA for all ur app and theme needs, as for the Iphone being better on battery. I dont doubt its better, but from my experience and many family and friends showing me there iphones they are always tethered to a power source. Theres no better test than driving 300+ miles a day every day and coming back to the hotel and seeing my phone tell me i have been using it for 20+ hours and i still have 25% charge. I am constantly using my phone for calls, text, movies and such. Without my phone my wife would probably divorce me lol The amount of travel i do via plane, train and automobile is all the real world facts i need. Vibrant is a keeper.

Yes it sucks.
And under 15% it's not allowing me taking pictures!
Come on, I know I am under 15%, but I still want to take 1 or 2 pic!!

"Battery Use" inconsistent with actual usage

The "Battery Use" reported by Android is completely out of whack on my Epic. It's the one under "Settings" and then "About phone."
For example, it's listing "Voice calls" as accounting for 83% of my battery use with 3h24m29s of time on. I know for a fact I've only talked on it for ~5min today. In fact, I was curious as to why it was showing 34 mins when I checked it at noon so I kept checking it, and by 12:15, it was showing 1h35m! Totally bizarre, not to mention most of the other battery usage times are off too, including a cell standby time that's shown to be longer than the time that the phone's been on.
Anyone else having this issue?

Haven't noticed this yet, but I'll keep an eye out for it. Out of curiosity, the battery drain isn't any different though, right? Your battery isn't being drained as if you talked on the phone for 4 hours?

Honestly I can't say. My battery life has been horrendous from the first day I got the phone. Have yet to make it through an entire workday with it. That is even when it just sits in standby when I'm at work. I don't know if that has anything to do with this usage indicator issue. But I went to the local Sprint store today. They didn't really know what was going on so they gave me a new battery to try out. I will report back if anything's changed.

Make sure you condition it real good. Like for the first week, give it a full charge then use it until it dies. I've done that and ran the battery until dead on purpose about three times the first couple days. If the battery is good, the life should get better and more stable. Also I suspect that, after speaking to the dev of battery indicator pro, some brands and models of phones report a ballpark figure and some are just about right on the money. My battery has noticably improved after these full powering cycles and topping off a few times after full.

Well, hopefully that fixes it. I've talked to a few people who have gotten amazing battery life using JuiceDefender to automate turning the 3G connection on and off, which people seem to all agree is the biggest battery killer sans display, and they are claiming going from 100% battery to 95% battery overnight, 2AM to 10AM.
If I leave my phone alone for an hour I will lose that much, and that's with the same JD settings. Then again, even with my EVO I found JD to be nearly worthless. Right now it's claiming 2.11x more battery life, but if it equates to anything in actuality I might be gaining 10 or 15 minutes. Maybe.

Mine is the same way. It sits on standby most of the day. But it still eats up the battery and the phone is always warm.

If 3G sucks as much battery as suspected, then google needs to put a button for it into the Power Control Widget (1 of my favorites).

Sounds like you are suffering from that bug where the phone is always looking for a gsm signal instead of just locking into what it works with cdma.
Press and hold the power button, select airplane mode. Let it sit in airplane mode for a minute and then repeat above steps to disable airplane mode.
Your time without signal should drop significantly thus resulting in a cool phone and much better battery life.
You need to do this every time you reboot the phone by the way. This bug should hopefully be worked out with the froyo update.

Reporting back after new battery and factory reset - still broken. "Battery use" says "Cell Standby" has been on for 20mins after the phone's only been on for 11mins. Seems to be an Android or Touchwiz problem.
Still waiting to see if the new battery will carry it through a 8hr work day. If that doesn't work, then I'm trading it in for an EVO. Too bad since I really liked the physical keyboard on the Epic.

Yep, problem I have is where I live I dont get any signal. I end up roaming thus causing the radio to kill the battery extremely fast. Last night i put the phone In airplane mode and let it charge. Phone cooled down even though it was charging.
So unless I get better signal without Roaming or I move I guess I am just stuck with not being able to use my phone at home or at work.

on mine my battery meter is all off also. my battery widget shows that my phone its at like 40% while my icon in my notification bar is pretty much full like it would be only at 70%... its not even more than half gone. so I know there is an issue with how my phone reads the battery or something

I, as well, see about a 1%/hour drain when my phone is not in use.
Usually, unruly battery drain is due to a rouge application you have installed.

I'm getting better than ever battery life on CM6.
Try charging all the way, reboot into recovery, wipe battery stats, charge all the way again.

I did something similar... I got it to warning (15%) and then erased battery stats... I then ran my my phone until it died and died again... after that it shouldn't get past boot if so then proceed to boot it into bootloader. The bootloaders white screen should drain back up battery quickly so only leave it on for only 2-3 mins. Charge it fully powered off and enjoy 15+ hours uptime!

my battery sucks ass too it was never like this before??? kernel??? could a different kernel fix this issue..if so which is the best please be specific so many kernel to choose if any...please help..thanks!
does the phone radio matter because im using the 5.8.4 i believe..

cyan 6 has had terrible battery life for me. so i switched back to leofroyo latest beta rom and got back my 3hr/% standby battery life. with widgets and email checking every 30 minutes. i'm down to 2hr/% in standby. usually in a day i lose 25% battery life with mild internet use and calling. i charge my phone every two days. can't beat that.

Try manually closing all applications & services that are not vital to your phone, then test over a day or two. If that doesn't work, try a different kernel.

Okay I've had about enough of this. It goes down to 15% every day EVEN IF I DON'T USE IT AT ALL
Could someone recommend me the best battery life rom in town, even if it's the stock one?

Try blackbar v6.1 or stockbar v6.1. Those are the FRF91 build. I haven't tried the FRG33 but it's probably pretty great as well. The first post lists the changes from stock.

I'm fighting with battery life too, but problem is not when in standby where it uses less than 1% per hour, but actually using it (browsing) you can see battery lose 1% every two minutes... is it like that for you guys also? Really frustrating me...

Don't do this. Draining lithium ion batteries to completely dead is one off the worst things you can do to those batteries. It kills off their capacity
Charge to full, turn off phone and charge again until led turns green again, then boot into recovery and wipe battery stats.
15 hour uptime is average not excellent

This is an excellent ROM. i've used it until i switched over to LeoFroyo. They both use the stock kernel and in my opinion i think its th best.
i also like to downclock the processor down to 800mhz with setcpu. definitely helps with the battery drain while using the phone. Non of those 925mv kernels help out in my experience.

Well I run go chat and msn constantly, I use 40 percent display, wifi, 3g, sync, etc and its about double the length I got when it was stock. Right now at 12% and I'm at 16 hours and 32 minutes! I wipe battery stats every time I flash a new radio also it seems to help

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 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.

Im only having problems with voodoo kernels. Flashed ec10v last night and had same issue. disabled voodoo and flashed back to eb01. did full wipe this morn and installed sc 2.9.2v and im back to same battery issue. its irritating.

No issue for me
I am actually seeing much better battery drain... I am on SC2.9.2V
im unplugged almost 4.5 hrs and im at 95% still....

sigh... working on battery calibration now. i have to leave for work soon so w/e i do it has to be now. lol. no comp access at work so i cant odin cwm if i break it. might just flash back to sc 2.9.2nv till i have time to play.

I feel your pain. In my case, and maybe yours, I think the culprit is the horrible coverage verizon gives me.

Attempting calibration. I will get back to you guys, once I finish, with the method I used.

Let me know how it goes. I've tried a dozen times with no luck. Maybe your method will work better.

Does your battery drop to 0 that fast?
I have had a time where by battery dropped 15% within 1-2 hours, but then I was stuck on a certain percentage for hours.

Hello, I started a thread 2 weeks ago and it has some good info there. Take a look.
I update the OP regularly adding post made by others. No one has posted anything in a week. If you find how to fix your problems please post it there and I will add it to the OP. Its up to everyone to keep that thread alive.

I've had issues as well. Mine are related to GPS wakelock. Every fresh boot I will consistently get a partial wakelock of 100% because of the GPS. Simply opening Maps and closing it will force the wakelock to release.
I'm curious as to why others aren't having this issue, yet some of us are?
I've tried the EB01 modem as well as the DL09 modem and its the same results. Aside from this, battery life is great...

When you say 'idle' do you mean like zero apps running (like stopping everything running via a task killer). Then what,, like keep the phone's screen lit up by not letting it sleep and monitor the battery drain over a period of time? I'll have to try that and see how mine does. I'm guessing mine will prolly drop 15-20% as well if I have the screen lit for a solid hour.. hmm
I didnt really think mine was working 'bad' though, I just figured thats about what these batteries in these could do. I can make it though a day without a re-charge but I admit I have to budget my usage of the phone thoughout the day.. not using it for long solid periods of time and such.. If 15-20% an hour drain would be considered 'bad', how much should it drop in an hour to be considered working 'well' in your opinions?

Well I spent all day charging, using and then recharging my phone. it died in about 5:45 hrs of med to heavy use. I used the method outlined in this thread. http://forum.xda-developers.com/showthread.php?t=987529
I lost 5% battery in 45 min this morning which would have been nice but it was idle in my pocket. :-(
I gave up... reflashed 2.92nv and im checking to make sure its not having same issue.
If anyone has more suggestions there are now 2 pages i found for this problem specific to the facinate.

My battery is pretty decent after clearing battstats. Heavy use I'll lose about 13% per hour. Idle is decent, 3-5% per hour.
2.9.2 ec10voodoo

Ok I did a little test with mine - I set my LCD screen timeout setting to 10 minutes, turned my wifi and gps off (left the cell radio on), killed all apps that were running in task manager. Then I sat the phone down on my desk with the screen lit up and tapped the screen every 8-9 minutes or so just to keep it from going to sleep for one solid hour. I didnt do anything else with or use the phone in any way during this time. My battery dropped 18% in one hour. Think I'll try the batt stat clear procedure and redo the same test and see if its any different.

Mine is horrible. For some reason, it drains in proportion to my use. If I use it constantly, and hardly put it down, I'm lucky to only get 6 hours out of it.
I don't get decent life unless I put it in airplane mode, turn off rotation, and don't use it. Then I'm good for
16 - 18 hours.
WTF¿

I can understand getting 6 to 8 hours if your a heavy user. but Im only concerned with my idle battery use. Juicedefender help some what. you can get it on the marketplace.
I'm still having the same issue with the nonvoodoo version. I'm still not sure how some users are getting over 40 hours of battery life.
as far as I can tell recalibrating my battery had no effect on the battery life. I plan on trying to recalibrate 1 more time in case I messed up the process. I will post my results in a day or 2. good luck to the rest of you. if you find anything out that may help me or anyone else please post it here
