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!

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!

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!!
I have had the ultimate in crappy battery life since day one with my Vibrant. I have tried reconditioning, task killers, freezing apps, etc., etc. Very minimal gains and, in some cases, worse battery life. These things were draining just sitting on our pockets.
Here's where it gets weird. My wife also has a Samsung Vibrant and was getting the same horrible battery life. We were both charging dead Vibrants half way through the day. Granted, we are both moderate to heavy users but I expected more. A week ago, my wife was still sitting at 80% by lunch time while I was looking at 27%. Huh? I asked her what she did and she had no idea except that she had downloaded a battery monitoring app the day before. I thought it made no sense that this could have anything to do with it so I brushed it off. Over the next few days she was still getting killer battery life throughout the day.
So....I decided to give it a shot just to be sure it wasn't that app. Well, just before bedtime, my battery was it 7%. I downloaded the battery app, plugged in my Vibrant and hit the hay. By noon the next day I was still over 80% I have no idea why but I know it's working for both of us and it has to have something to do with this app.
I'm no programmer and I certainly have no vested interested in any android apps. We just stumbled on this and it works. Would anyone out there have a clue why?
I'm not sure if posting the name of the app breaks any xda rules so I'll wait.
Ever since i've been on JK2 Froyo my battery life has been excellent. But i'm interested in hearing which app you're talking about

I agree. I just didn't want to be seen as peddling a product here.
It's called BatteryTime. It's free although, I believe there is a pay version. I didn't adjust any settings. Just installed it, charged over night and I can't believe the difference nor understand why it made such a huge difference. I unplugged 4 hours ago and have 98%. Still a mystery to me but I'm not complaining.
There's like 4 of the same app on the market x)
What is the full name?
OH and thanks, I installed it, I'll report back with results.

Just Looked again and you're right. There are 4 versions there. I'm currently using the "BatteryTime Lite" version.
The only thing that I can think of to rationalize this huge difference is that the battery percentage was being reported incorrectly before. I may have had a charge that would last all day or longer but it was displaying an accelerated discharge rate which would kill my Vibrant prematurely. For one reason or another, this app appears to have corrected that and the indicator is (I hope) reporting the correct battery life now.
Does that make any sense?

Thanks for sharing. I will give it a try.
Update:
I found this somewhat disappointing. I rebooted my phone for the first time in about a week and on boot up the indicator is displaying significant drain again. I was at 96% before boot and 56% after? I'm going to recharge to full again and see if I still enjoy the same battery life.
Now I'm really confused. Sent an email to developer.
judging by the app description and most of the comments - the app doesn't actually *do* anything. It merely reports the battery differently.
No amount of software will change how much charge a battery can hold. The only thing that's different is how it's being reported.

Indeed, and that was my point to begin with. Originally, the battery indicator reported as critically low in no more than 6 hours. Soon after, the phone would shutdown until put on the charger. With this app I am able to get through the day reporting roughly 30% at bedtime around 10pm. Of course, that is subject to change on a reboot....until fully charged again. This is the mystery.
Yeah, there is funky stuff going on with battery meters. One that is included with the Obsidian Roms is Battery Left, currently, this is showing a 50% charge and 10:19 left. Next to it is Juice Plotter which is showing 21h 11m left. According to the system, i am at 71% Power and it has been unplugged for 6 hours. From experience, I know that the 21h remaining is actually accurate and Battery Left is completely dorked.
The point being, you can't always trust the battery meter.
So I installed a monitor also to try and figure out what was killing my battery 30+% over night and I had the same reaction....I woke up to a 10% loss. I realized what is probably happening is since this app is monitoring the phone all night...whatever app is draining the battery is probably a daemon that only runs when the CPU goes really idle for a certain period of time. More than likely that app inadvertently gave you better battery life because it runs in the foreground and marks your phone as being active so whatever app was killing battery never ran.

I think you've hit the nail on the head. Since day one, I have had buggy battery reporting. For instance, if I reboot the phone while it is plugged in, the reported battery level changes dramatically.
Edit: your later post supports this idea even further.
I installed this on my phone. This program does not attempt to save battery life or control anything on your phone. It does offers "Tips" to save battery life. Its main purpose is to indicate, based on your current level of charge, how long your battery should last given different circumstances - ex. idle, talk time, video time, audio time, etc... Thus the name BatteryTime.
That's all that it does. Any perception of a longer lasting battery may have been an anomaly as does happen sometimes with our phones. One day you'll seem to be getting awesome battery life (and there is likely an underlying reason which we'll never figure out, but which jives with the battery) and the next day it is back to draining quickly as normal.
There are three certainties in life: death, taxes, and posts about battery life in smart phone forums.
Anyone have the issue where they charge the phone overnight, the phone reads 100% in the morning, you unplug it and you are immediately down to 7% battery? It seems to happen to me at least twice per week. It is a terrible bug.
i dont get it you said that before the battery wasnt being read correctly so it shut off fast but now with the app it reads correctly and last you the whole day with 30% left to spare?? wouldnt that technically mean it increased battery because you got it to last all day plus some? just by making the phone read the battery correctly.
How is the battery holding up for most folks?
I've been using Atrix for a few hours tonight (perhaps a bit more than normal use was on my Nexus) and I've already used 50%. Thats pretty crappy for whats proclaimed to be a large, long-lasting battery.
What should I be doing to improve battery life on this device?
Thanks.
I've seen the same poor battery performance. I'm hoping after being on the charger all night I'll see the battery performance that I've read about.

It's called "New Battery Syndrome give it a week, you will settle into your normal usage pattern and you will really see fantastic battery life.
Pretty much, you have a new toy, you want to play with it as much as possible, thus you run it more than you may have used your previous devices thus effectively running the battery down faster.
Mine seems to be pretty great. Have had the display on for about two hours straight and it only drained 20%
naturefreak probably nailed it. most batteries seem to last longer after they've been discharged and recharged a few times.... on top of playing with it for probably just about the entire day..... BOUND to see less-than-expected battery life.
SGS Vibrant flashed with Trigger 3.2 the battery lasts for 1 day with wifi usage and even if kept for overnight it drains about 18-20% of battery should i move to a different ROM ?
You could
Sent from a cell tower to the XDA server to you.
Trigger has had one of the best all time battery life for me a everytime.
I think you need to
A) recalibrate
B) re-check to see if any apps are using battery life.
C) flash a rom if none of that works.
Here we go again for the millionth time.....
But for me trigger had the best battery life.
I'm not on the gingerbread roms and it takes me from 100% to 5% in 8 hours overnight even WITH Juicedefender (seems to be about the same without it also).
If anyone has tips on THAT, I would much appreciate it. I've tried calibrating the battery.
There is a setting that you can turn your radios of from x time to x time overnight. I have mine set for 11-6. If I am on after 11, then I take priority. If not then the setting does.
There is also a setting that will open data/radio every 15m/30m/45m/1h/2h or something like that to get updates for somethings (i.e. Beautiful Widgets). I have mine set at 2h. If I want my data/radio open I will do it myself, hence my long interval.
Been using this app for well over a year so I know how to tweak it a bunch. If you have JD+ see my battery guide and it will tell you more about its tweakiness.
Trust me. This guy knows how to use JD, check out his battery guide. It will be worth your time.

i wish i could get my phone to last a whole day without charging, i just dont complain because i know for a FACT that the reason my phone only lasts 10-12 hours is because of ME. im too stubborn and refuse to switch to battery-friendly usage. the biggest thing that impacts battery is the user/user apps. not rom, not kernel, the battery difference from rom-to-rom and kernl-to-kernel is barely noticeable (unless in the rare case where there is a bug, or developmental defect). if there was ACTUALLY a rom in exsistence that TRULY had superior battery life, then you wouldnt get 5-10 different answers in every single "what is best rom/kernel for battery" thread.
the problem is, people want to believe that they can save battery without changing their usage habits. this simply is not possible. no rom or kernel will realistically do this for you. if you remove 1 brick from a bag full of 15 bricks, the bag will be lighter, but still very heavy. you need to download "spare parts" or "process monitor" from the market and start analyzing the way your apps are acting. also look into data syncs that are happening in the background. apps that stay open behind your back/what they are doing, (an app called "autostarts" can prevent apps from self-running under certain scenarios). animation speed. polling for notifications. gps. wifi scans. overclocking. cpu/ram usage. proper sleep. widgets. brightness. 2g/3g. data usage. call time. text volume. - THESE are the things that really affect your battery life.
bottom line is, if you truly want to save battery you are going to have to get your hands dirty...there simply isnt a one-click (or one-flash) solution.
Hmm so i'm now on MIUI and it seems to be giving better battery life, also have been thinking of getting the extended battery for Vibrant is it worth ?
If it sucks so bad, grab one of these. I have it and it has given me at least a 20% increase in battery life. BTW, you must listen to the instruction for the Battery if you get it. 4 or 5 full Drains to 0% and then charge to 100% while device is powered off and re-calibrate after each of these full charge cycles.

So I've been using this phone since 5am (its almost 2pm now), making and receiving phone calls for the last 3 hours, using the internet while in calls (some people are boring to talk to), playing games, and listening to music off and on for a while, and I'm at 74%.
Now, to some people who really tweak their phones, this probably doesn't mean anything to them. However, I have had an Evo 3D, Droid Razr OG, and Galaxy Nexus, all of which I completely tweaked, and wasn't getting this battery life. I am rooted with a stock rom, but my hatred for TouchWiz forced me to use Apex Launcher. Other than that, no modifications at all, no flashed kernels, nothing.
I've only had this phone for a little over 24hrs, so I'm wondering, with all the reviews complaining about battery life, and even threads in various forums with users complaining about battery life, is this normal? Is the battery life great at the beginning then gradually gets worse? Or is it truly dependent on the use I give it? I'm in an HSPA+ zone at my house, but I have LTE when I actually go into town. Any ideas?
It seems like there is some debate on whether there are some people getting "good batteries" and some people getting "bad batteries". I know that my wife and I are both seeing what I'd call phenomenal battery life, and that's with no root, just disabling a few apps, and we're leaving everything except Bluetooth on all the time (and making sure it's not trying to find an LTE signal, since there is none here)... so clearly we got "good" batteries. I also ensure we don't have any rogue apps, or things running in the background that we don't really want there, but that's the extent of "tweaking" I've done. But, like I said, there's definitely reports of people seeing bad battery life, so not sure what the deal is.
that's not normal...I took mine off the charger at 7 a.m., used it for about 45 minutes worth of phone calls and by 11:30 I was down to under 70%.
My battery life sucks. No where near that. My phone has been unplugged for 2.5 hours and I'm down to 60. That sucks.
I only got into this phone because of the battery life. I may switch out. I'm not getting anywhere near the advertised life

I am getting better battery life after uninstalled Chrome. But since I live and work within an LTE area, it's still not phenomenal.

So based on what you said, in 9 hours you used 26% of the battery. This would mean that the 2100mAh battery was sustained at an average of 61mA over the course of your usage. This seems almost impossible considering what type of use you put the phone through, Unless you phone is idling at under 20mA (mine is around 30-50) your battery stats might be inaccurate. If you continue using your battery at this rate and usage it should last you 34-35 hours with what looks like heavy use. You can use battery monitor widget from the play store to view your current usage and see what type of power your phone is actually consuming, as it is directly related to your battery life.

that's not normal...I took mine off the charger at 7 a.m., used it for about 45 minutes worth of phone calls and by 11:30 I was down to under 70%.

More like that's not normal.

Your argument is completely valid which is why I posted this thread to begin with. I wiped battery stats and all that, so it might be giving me an inaccurate reading as I pretty much never let my phones die, although I read in some places that wiping battery stats makes no difference at all and is basically useless. I'll download the app and let it run and I'll post back. I did post a screenshot with the time I was on battery and the battery percentage that was left, but as mentioned before, since most of the actual usage was phone calls, I didn't have the screen on that much.
I've had mine for about two weeks and I consider my usage to be medium-high a lot of the time. I can't complain with these results. I'm completely stock, no root, no apps disabled.
As far as Chrome, I don't know what it does but I've read in other threads that it does drain battery.

I kept seeing Chrome use CPU even when I had all the tabs closed. Quick internet search revealed several threads about it draining battery so I decided to uninstall it until it gets out of beta.
However, my battery drained dead over night again. I did hear my notification go off prior to bed. I am now thinking the led is killing my battery so I turned off just now for notifications.

If people are having very bad battery issues it's due to how the phone is set up and syncing. Sure there are the super rare cases where the phone is actually broken in some way.
S3 has the best battery life stock behind the razr maxx on Vzw at least.
Any good current apps like "current widget"?
