Battery Life?

How has everyone's battery life been with the Vibrant? I'm having a few issues with mine, I barely used my phone today, and its down to 57%, with cell standby taking up 33% of the battery.

Search the threads.seriously there are like 5000 battery life threads

So is there a fix for it? Or is it all samsungs fault? Or will the update solve it? This sucks, my battery can loose 30 percent in a matter of 2 hours...

Your battery has and always will react to the way you use it. If you a new user and play with it all day then its going to go fast. If you use 3g, wifi, bright screen you are going to get crappy battery life.
If you use it like a normal person with 6 to 10 calls a day, light web usage, some text messages you should get a battery to last you all day.
Fire up the screen and watch videos or listen to mp3's all day well then your not.

I turned off every little thing, and i still get crappy battery. Wifi off, gps off, sync off, wallpaper off, the whole shabang.

Does your phone actually die, or does it just show a percentage you are unhappy with?
The measurement seems to be a bit off on the Vibrant.

I was disappointed woth my battery life as well. But I wiped the phone and the battery performs better in my mind. Anyone else have a similar experience?

After discharging/conditioning it a couple times, my battery is much better. 9 hours of standby overnight, it only lost 10% battery. That's pretty good IMO.

I just unplugged my phone an hour ago, watched some videos, browsed the web and my battery is down to 86%. It dropped 14% in less than an hour!

Is this your first smart/android phone? Your battery doesn't sound far off for an high end smart phone.you'll eventually learn how to extend the battery, especially after the newness wears off and your not playing with it 24/7 like most of us right now.remember this is an extremely high end phone, it takes a lot of juice to run the high end chip set.if you buy a high performance sports car do you expect to have some fun with it and get 30+mpg doing so? You've gotta understand what you've got. Soon enough there will be extended batteries available and if your willing to root, many devs are capable if tweaking the os to get the most out of the battery without hampering speed our features.

I'm having major issues too. Down to 28%(down to 25% now just typing this message) after 3 hours this morning. I just powered off and back on and I went from 50% down to 28%
Here we go again g1 all over again Seems like the only way to keep power is to uninstall everything.
I'm also seeing cell standby as a possible issue.
Frustrated... Guess it's time to reset to see if one of my apps is the issue...

I have 35 percent left after being off of the charger for 1 day and 5 hours. This is with light to moderate use, meaning some browsing, some phone calls, some market downloads, about 20 minutes of gaming, syncing, and reading e-mails. Of course my mileage varies if use the phone more. When the phone is about to die I'll snap a pic to share how long a full charge has lasted me.
Already this battery is lasting me 2-3x longer than the G1.

I tried a different battery and it's been really good to me =)

What percent do you show for "cell standby" from setting->about phone->battery use? I'm starting to think that my poor reception area is my issue.

I think the battery percentage shown in the Status is off compared to what is shown on the battery icon. That said, my battery lasts all day with normal use. If i use the web more than normal, of course the battery goes faster but still i usually get all day out of it. May have to charge it some in the evening.
Was hoping it would be better like the iPhone 4 battery seems to be. It is said that 2.2 will have a bit battery life but we'll see. Believe it when i see it.....if we ever get the update

My wife and I got Vibrants at the same time. She was getting great battery life, around 70% by the end of they day, and I was dying just after 1pm. I assumed that i had a defective phone, but decided to wipe it and try running "stock" prior to returning it for a new one.
After wiping the phone and starting over, I'm getting much better battery life, but I think that it's because I didn't use "push" email. I have a corporate Exchange email/calendar/contacts account, and before I had it set to 'push" (or something like that, my phone is syncing DoubleTwist right now, so I can't check. ) When I re-setup my email account, I told it to check only every 15 minutes.
My battery life has been much better this time around, and I think the email sync setting is 1/2 the reason, the other half being that T-Mobile coverage isn't great where I've been the last week. I'm guessing that the "push" sync meant that the phone needs to keep a data link to the server, which is fine if you have strong coverage. When it's weak, then the radio has to work overtime trying to maintain a link, which drains the battery.
I'm going to try this out today and tomorrow, and if the battery life is better than I'll keep it rather than try trading for a new one.

For one, if you're having a battery issue, buy a charger or spare battery. Get a task manager to kill your apps after a certain time and check into what services are running in the background. Just cause you're not playing with the phone doesn't mean its not running or using the battery.

Cell Standby is at 24 percent.

Maybe its some quality control issue in the batteries? Everyone is getting such varied battery performance. I'm thinking of calling T-Mobile and requesting a new battery.

I notice on reboots many apps get started automatically. I've gotten better battery life just by manually shutting them down with astro file manager app. Ultimately any time an app is running even if its not using cpu cycles it still costs power to keep it in ram. Manually shutting down will minimize this obviously.

Bad Battery life all of the sudden

Only thing I did different was turned on google talk and my battery went from 100% down to 24% in 4.5 hours. Could google talk really take up that much battery? Prior usage I would get over 18 hours, thats with texting, emails and a couple of voice calls. Previously under the battery use the screen was always at the top but now the Android system is at the top.
Guess my main question is could google talk hit the battery that hard?

Did you recently root? Mine seems much worse since rooting.

There you go. Gtalk must be accessing the internet often which is causing the drain in battery.

I have noticed if I leave a page open on Google Buzz, the GPS radio can drain the battery quick.
Another reason why I want to have a development ROM with all those nice troubleshooting tools to catch these problems quicker. Like before the battery is dead.

I have similarly awful battery life on the Vibrant, and I've been running GTalk 24/7 since I purchased the phone. Going to run it with no GTalk today to see it affects life. I'll post my results here later.

I'm rooted and I still have 23% battery after 29 hours unplugged. Any other apps you got running in the background killing your battery?

After I rooted I didn't add back the Facebook and other accounts that keep the contacts updated with their status and whatnot. I get a full 24 hours out of a charge now so I am really pleased with the battery life.

I am running mine rooted, gTalk on, google sync and one exchange push sync always on, "Twitter" twitter app updating @ 30min., LauncherPro, live wallpaper, gps on standby, and I have to say coming from G1, 3G Slide, HD2, this has the best battery life so far. Not playing any games on it, nor any media streaming aside from the occasional few minutes.
Now, it has only been two days running it that way, but one can hope it stays like this! Running it unplugged from 7am to 1:30am (next day) and still having 45% battery left after a day of medium heavy use is pure bliss!

im sorry but i am every good with phones and adjusting the battery drain and this seems terribly inaccurate unless you pick up your phone once an hour and use it. There is no way you have almost 50 percent better left on this device while running all of that stuff. and you have it on 3g? or edge? is the screen bright?
overall the battery has been TERRIBLE. and it takes forever to charge. that's why i sent it back. I hate USB charger cords... seems they take loner to charge.
much love u must have an extended battery which isnt even out yet lol

Well, it was google talk that was doing it. I work in a large building and get about 2-3 bars of service which isn't bad but leaving google talk on literally raped my battery.

Thats an awesome idea!!! Facebook sync is almost retarded to have on this phone since im not running TW or looking through my contacts to check on ppl... there is no reason why I should even have to keep the account synced. The service is still probably running in the background and dropping/retrying. Thanks!!!

AWESOME! Thank you OP for testing and bringing us back your findings. This is how it should be done!

I've had my Vibrant since roll-out day. The battery seemed to be working well and lasting a long time. Then it began to drain rapidly going from a full charge to under 25% in about 4.5 hours. This happens with or without use. I tried disabling sync, wi-fi, push, bt, etc and I didn't see any improvement to speak of. I also set it to use 2G networks only. That was all before rooting yesterday. Today it's no better at all so rooting doesn't seem to have had any effect.
As far as charging goes- it's horrible (mains, not computer); over 4 hours from completely dead (auto-shutdown) to 100%. Even if I begin charging at 35% it still takes over 3 hours to get to 100%.
What does all this mean? Beats me. I like the phone and I am hoping it's not a hardware issue. My rooted G1 with an extended life battery running Froyo lasted all day long with constant data use, go figure.
I'll be watching the forums over the next several days with the hope that something will break loose.

Nope, just a stock Vibrant battery. Phone lays next to me on my desk at the office all day, bounces between Edge and 3G here, currently, 2:16pm, the battery status in the phone settings shows a level of 76%, was unplugged this morning @ around 7:30. At my house I have full bars 3G. Battery use is 35% Voice Calls, 28% Display, 18% Cell standby, 13% Phone idle, 3% Android system and 2% Android OS.
I am not much into adjusting battery drain or anything like you, but those are the readings from the phone. How accurate they are or not, no idea, but this is definitely the best smartphone I ever owned concerning the battery life. And I owned a **** ton of them over the years. But I also don't complain too much, because getting through a full day is all I need.
Screen is set to auto-brightness with the application brightness thingy activated.

Edit: Reading my original post, I guess it could be a bit confusing - I did not mean it has lasted for two days like this - I meant I own the phone only for two days, and it was unplugged yesterday from 7am to 1:30am next day (18.5h)

It is a legit question. On my N1 and this phone I see HUGE differences in battery when the device is in heat/pocket and inside just sitting on a counter.

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.

Charging twice a day here. Its worse than my hero.

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.

hey that's really impressive. I thought my 20 hours battery life was pretty good...kudos to you.

def getting better bat supply. especially from my hero which only lasted about 6-8 hours, just got my shift yesterday afternoon. from a full charge: Constant texting, facebook, Zenonia 2 (Downloaded wifi), Snes emu + 11 roms (3G), and customizing it to my hearts content. almost 12 hrs later had 20% until i plugged it up at work.
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 )

Its under # 13 on my 3rd post.

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.
Sent from my cm7 Evo 4G!

Working on calibrating my wifes battery and damn this thing is hard to kill. Even with with everything running for 5 hours its still over 20% finally decided to bring out the big guns. Turned on navigation and the flashlight. I'll post when I see the battery life after calibration.
Sent from my cm7 Evo 4G!
Edit: Phone plugged in at 7:53pm PST. Now to see how long it takes to charge.
Edit #2: Phone finally fully charged almost an hour after my evo finished its 0 to 100 at 12:19am
Edit #3: Holy F***. This phone takes forever to die and to die. Finally on the second off charge. I wouldn't still be doing this but for the fact that its saturday.

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.
Sent from my SGH-T959 using Tapatalk

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.

My solution for SGSII battery drain after root

So, I decided to finally root my SGSII..and everything went smoothly..n I was happy knowing that now I could do many things with my phone...it eas working normally with no issues but, after some weeks, my battery life was just awful..it wouldn't even last 15 hours..n I was worried..started searching for solutions, but didn't find them..n then Istarted getting used to to this poor battery life..
Now the interesting story..
One day,I went to fetch my SGSII n I was expecting it to be off, with no battery, n thats what happened,n I didn't even bother charging it..it remained fully discharged for, I think more than 24 h, then the next day, I needed it so, I fullY charged it, turned my phone on, n started using it..
by night I was expecting my phone to be fully discharged..BUT, it wasn't the case this time around as my phone's battery started working normally..just as it before...
Try it...at least it is not risky

Sorry, I saw empty post. My response is now useless.

But... how will I survive an entire 24 hours without my beloved SII?

Most people just learn why the battery drain occurred. And fix that.

Basically this works with Battery Cycles - discharging your phone from 100 to 0 and charging it all the way up again without interruption; has proved to be a handy way to keep a healthy battery life just as my SII has did.

do u huys have experience with battery caloboration apps?

They don't work. Ignore them. Simply charge your phone to 100% from flat and its battery will be calibrated.

Also disable chatting programs like msn messenger, whatsapp, kaokaotalk, facebook will save your battery. Those apps keep updating and sync at background.

Never had a issue with Whatsapp or Facebook when set to PUSH mode rather than scheduled updates.

Epic first post. I found that if I don't use my phone, the battery lasts longer than if I do use it. Hope others share their tips too, as there's a shortage of battery threads.

Its not that important that you wait 24 hours.
The most important thing is that you let your phone discharge until it has very few percents left or even shuts down by itself.
If you then fully charge it while it is shut down you should get much better battery results with your next circle :good:

battery life
my battery life is awsome!! after 22 hours of a very little bit of use i had 76 % battery life left !
siyah kernel 3.5.2
rootbox JB 2.0

i had almost 2 day with rr 2.6.1 and cm9 . i think that this is the perferct combination for baterry.

Leaving empty (0%) lithium-based battery without charging for more than 2 hours is stupid - lithium batteries are degrading very fast in empty state.
// tip for notebooks and phones

i getting also faced this problem too. Empty that battery and charge handphone on offline to make it fully chargging.

Don't worry about the battery life. Just use the phone through the day as God intended, dock it at home or in the office and charge it over night.
Job done.
