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 ?

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 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.

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.

Is it normal for my battery to only last 1 day before it needs a charge? I have everything turned off practically and yet I still have it dying after 1 day. According to Battery usage, the only things draining it are the Display and Cell Standby. Any information on this would be greatly appreciated.

That's about the battery life I get. With light to moderate usage, it lasts about 15 hours before getting down to 20%
I'm in a fringe area and get most of a work day with moderate email, data, and constant music

Same here...11-13 hours is a pretty good stretch for me.
Biggest culprits for battery drain are display and automatic data syncing.
So if you want to extend your battery life lower the brightness on your display.
So for syncing you can either disable it completely so that your applications only refresh for new data when you use them or change the frequency that they check.
I'm getting about the same. Actually I was pretty happy considering all this thing does. Keep an eye out for the extended battery. It's gonna make it thicker but might be a good tradeoff for some of us.

My battery only lasted around 6 hours, so I'm getting a replacement.
I'm with you guys about the battery issue. I mean I know that Android is known to have bad battery life, but the X was heralded as supposedly having decent battery life.
Even with GPS and wifi turned OFF, and my display brightness turned all the way down to 0, I am still only getting about 10-12 hrs of usage. That's BS.
Overall I really like the phone, but the battery issue is getting on my nerves - as well as the damn wifi issue.
I doubt it's going to matter, but I can only hope that Froyo offers up better battery life (maybe more options to turn stuff off). I would love to be able to underclock the CPU or reduce the screen brightness even more.
I am coming from a blackberry that got two days on a charge. The phone sucked though. I get about 13-15 hours per charge on stock battery. I use tasker and y5 to set profiles that toggle wifi and gps so I'm never using extra battery but still able to use device to fullest. I also went on ebay and found two generic batteries with external charger for $13. Now when my stock battery dies, I just throw in a new one that freshly charged and charge up the stock one. Having three batteries to shuffle through means my phone is never plugged in, and never dead. Plus in not charging batteries as often so it should extend over all life of batteries.

I use the widget "Extended Controls" and leave my WiFi, GPS, Bluetooth, etc off unless I need them.
I had the SGS Captivate for three weeks and before that I had the G1 since it came out - the DroidX battery life is longer than both of them.
I'm really happy with the battery life so far.
Also, I read somewhere that it can take a few full drain/full charge cycles to get the most out of your battery. Both myself and my wife completely drained and then completely charged our batteries within the first two days.
I've had the DInc, eris, droid, and nexus one, i couldn't put into words how much better the battery is on my x. I mean its nothing like a dumbphone. But this thing packs as much punch as some older laptops so i don't expect a lot out of the battery. Check ur apps, sometimes u get ****ty" rogue" apps that screw it up, and if u use a task manager only kill intense apps like web or messages or gmail. The other processes are need to make the phone run correctly, i know i've seen better performance and battery life since i stopped using one.

I leave everything on wifi, gps, auto brightness, blue tooth, and im getting the best battery life of any phone i have ever owned, even better than my nexus one . My sister has a Droid X, and all she does is complain about her battery life. Although she is coming from a blackberry, i think that most people expect more from the battery than it can physically give, if you wonder about how long it lasts just take a look at the screen, and realize it takes alot of juice to run this huge beast .

I had never heard of this before so I did some research and my X was doubling the time on in Cell Standby and showing 50% used. I was getting 12 - 13 hours of battery life. I did the airplane mode cycle trick and now I'm getting 24+ hours of battery life. And now Cell Standby displays normally. Amazing.
A big thanks to xmunk as that was the only thing that was driving me nuts about the X and I was thinking about getting a replacement. Now the battery life is great!
I would recommend anyone having poor battery life check to see what Cell Standby is reporting.
Oh wow.... Im showing since unplugging my phone 3hr 54m ago I've used the following for power:
51% Display
38% Cell Standby
12% Phone Idle
I just cycled Airplane mode and will checkout what happens next.
That a ton of power being used for standby. My Nexus one used 1-2% per hour while not in use and on standby. Battery left is estimating my battery is at 76% right now with a system % of 80% showing.
I hope this gets looked into.

Well- since you guys have already done all the work -would you mind maybe sharing a few links?

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.

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%....

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!

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?

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 don't know if it's my imagination, but since the 2.4.6 update, my battery life has dropped a bit. By the time I get into my office from my morning commute, I'm anywhere in the 65-70% battery life after unplugging from a full charge. I haven't done anything new. I always unplug around 8:30 am when I head out, I do some light chatting with gf, browse some sites, check facebook (usually very briefly), and maybe sometimes do a little reading on my device. By the time I get into the office around 9:30 or 10 AM, I'm usually around the 80-85% area with battery.
Lately, doing the same thing, I'm seeing the aforementioned 65-70%.
Is anyone else experiencing decreased battery life since 2.3.6?
I'm on a Tmobile Nexus S, running stock 2.3.6 (no custom ROMs).
2.4.6 ? .... maybe 2.3.6 ... and yes, I also noticed a slight increase in power consuption after the upgrade. The stand-by is still great .. about 0.8 - 1% per hour.
Sorry, yes I meant 2.3.6.
Thanks for replying Ro_explorer. Is your increased power consumption significant? Seeing 65-70% when I'm used to seeing 80-85% as I get into my office, I find, is a large change. To be frank, the battery life of the Nexus S in general isn't so fantastic to begin with... this hit makes it worse.
Anyone else?
I used to get home with about 40-50% after a whole "normal day" (unplugged at 8AM, and getting back home at ~8PM) .. now (with the same average usage) I'm getting home with ~30-40% ... that why I said "slight increase" ...
Not your imagination, I too have noticed this. I hope the next update, will fix this - as I used to get pretty good battery life (even with over 250 apps).
When I recently updated to the 2.3.6, it caused a bug of continuous reboot (every 1-3 minutes), so I had to do a hard reset - now it works fine, but I only have added back about 15 apps - and the battery life sux!
Downgrade OS' it will be ok.
This is so weird. Why is the battery life worse?

You want bad battery life? Try an Evo 4g with a Sense rom. I averaged about 6hrs using a 1500mAh battery, in stock form.
The nexus is pretty light on power consumption, if you ask me. I average 15hrs on the stock 2.3.7 rom/kernel combo, with stock battery.

I also noticed that the battery last less time
I've been waiting to see if anybody else reporting this issue
i noticed a decent increase in battery life going to 2.3.7 and thought that previously the battery life had been fairly poor :\
I am non rooted, and get around 20 hrs on light to moderate use. Again. Stock, non rooted.
How do I recalibrate my battery? I wonder if it could be that...
There are many was to recalibrate. Some involve wiping batt stats, some plugging and unplugging phone several times after charge.
I have always found that using the battery almost all the way down, but not past 5%, and then full recharge conditions it very well.
Oh I've been here to solve the problem
"Why last 2 weeks my Nexus s drain battery so fast ? or I have to calibrate it"
Thank for your notice about update OS to 2.3.6.
I think that's a root cause for me too.
1. Could I rollback to 2.3.4 ,how?
2. Does battery calibration is useful for this case , how?( someone suggest to calibrate when flashing new rom )
Thank you very much..
i want to know who have some methods to do with this stuff

Whenever switching roms, kernels, or batteries, i always perform the following :
1. Charge to a true 100% (Battery Monitor Widget will register +0 to +2 mA)
2. Wipe battery stats using recovery (Amon RA has this option for the Evo, not sure about cwm), Battery Monitor Widget, or a dedicated app.
3. Discharge battery to 0% with normal usage. When the phone shuts down, I pull and re-install the battery and power back up (it will shutdown again very quickly).
4. Recharge battery and be on my merry way.

I found one workaround solution for this issue on
ww.google.com/support/forum/p/Google+Mobile/thread?tid=1684c50cea15282a&hl=en&fid=1684c50cea15282a0004af022e5ed212
Sproogle77 's solution
Problem solved. Using the OS Monitor app, I found that the main culprit was Google Services - the Contacts sync specifically. Even though I had this disabled (only Gmail was being allowed to sync) it was constantly working, apparently trying to fix a location. The message log showed that it was generating continuous debug messages, all about locations - around 10 of these every second.
I have solved the problem by disabling 'Use wireless networks' under the Locations & Security settings.'Use GPS satellites' is still running. This immediately dropped my CPU usage - which had been running around 30 to 40% even when otherwise idle, to around 10%. Google contacts sync is now using 0% of the CPU. The difference in battery life was pretty much immediate and is now back to what it was before - the change in the slope on the battery usage graph is remarkable!
This doesn't really seem like a solution to me, and I don't know whether other aspects of my functionality are being affected, but at least my phone is properly useable again.
I'm testing for 1 day and I think that's working for me.

This is so weird. Why is the battery life worse?

One reason is that the new version of the stock kernel removed a speed stepping, so it'll power to higher levels faster, thus using more battery.

That actually isn't the problem. I'm using netarchy's kernel and still get this problem.
My battery life dropped from 16 hours --> 6 hours. the slope on my battery usage life is horrible the system is also awake almost constantly even when I'm not touching it / getting no messages.
I will try the fix suggested on the google support forum and see if that does the trick. sloppy update.
Hello all, I would like to know what % to start charging my phone is better to the battery? it's draining so much and there is no extra battery for sell in my country yet.
I did search many posts and all answers are different. I am so serious only this and I hope I can have a better way to keep my battery longer... thanks for your attention.
it's usually not good to let the battery totally discharge. So charge it before it completely dies.
oh really... but I already made my Note battery to 0% and shut off itself two times I also did charge on 40-50% to 100% bcoz I know I would have to stay outside without battery charge after. I wish I can get an extra battery in my country soon.
Your problem is probably not related to the battery but to some apparently draining all the juice. There is an app called something like betterbatterystats, not sure on the spelling though, it might help you to find those draining apps. It's been reported manytimes here in XDA.
And for your information it's better to charge when the battery dies for the first couples of times. I don't think that it makes a big difference after that.

U may also want to check the process or apps running on the background?
I freezes all the unwanted apps or process les one by one to try it. But in terms of the batt usage, I believe if u don't use it much often u can still stand by for at least a day. Mine running on full 3G, but screen brightness set to lowest and STILL facing some batt drain issue.

Charging from a total 0 is actually good and most technical people will suggest the same. In fact a full battery drain every month and then a full charge ensures your battery gets a full charge and a complete battery rotation. This is a good thing that you did and let no one tell you otherwise.
However, for normal usage the lower the better at which point you charge is best.
All of these batteries comes with xx full cycle charges - meaning how many times they will last from 0 to 100% before they degrade and start giving less efficiency (around 85% on future charges) after the full cycle charges are over.
You may want to use 10% as a good benchmark to ensure you dont lose an important call with your phone off. The battery saving mode on the Note will also help you reduce loads at times and improve battery life (at cost of system power).
Congratulations on using the Galaxy Note, which I feel is the best all in one device in the market!

I second this.. its funny how still people still believe those myths about batteries (like charge 100% before you use the device first time).. those issues are easy 5-10 years old.. batteries now a days a have smart chips built into them that can control the battery health
So, I can charge my battery anytime when needed?
Also, for screen brightness, i set auto brightness is better than setting it manually low?
