Battery life? - Fascinate General

Does having usb debugging on effect battery? I left it on today and noticed horrible battery life, phone was at 15 percent at three pm lol, minimul usage. I am running a over clocked undervolted kernel woud that have something to do with it?

I'd guess the overclocked kernel is your issue. Also, check your battery usage in settings and/or spare parts to see anything that stands out. If you have high cell standby usage or a high running time, that would also be a culprit.

I've been running OTB Test 5 1.3 for several weeks now and have great battery life, much better than stock. I would look in your battery usage to see whats using up all the battery like imnuts said. High cell standby drains battery really bad so if thats up there then I would start using airplane mode more often.

Its at three percent. Airplane mode is not an option, then I could miss important texts correct? And not be able to use internet right? Yes battery life is horrid right now. I tried using set cpu to lower cpu during screen off time an my phone just shuts off when the screen is off for any length of time. I do run my screen at 100% tho.. Might just try a different kernel

Profiles in SetCPU don't work on our phones. They cause it to freeze, like you're experiencing.

Is there a reason you need to run at 100% all the time? That's probably your biggest battery drain.
At least try setting to auto.

Alright I did *22899, charged to 100%, turned off and charged again till 100%. Booted then booted into CWR, proceeded to wipe batt stats, Dalv Cache, and Cache Partition. That was at about 1am, went to bed and woke up at 9:30, phone off charger all night and it was at 75%.
Cell standby 41% T/O 9H 50M time without 0%
Screen brightness is up because thats why I bought the phone, this screen is awesome. Battery life was never and issue before I rooted and started with the roms and kernels.

Best I expect with all the antennas on except bluetooth is 7-12% drain overnight. The number one battery killer is the sAMOLED display.
It is rich in contrast and pleasing to look at. The screen resolution is good but a tad grainy. They say the pixels are off when black, but a slight glow is always detectable in a completely dark room (boot up your phone in complete darkness, the black screen looks different on than off). It can also burn in, so I recommend hiding the status bar up top or at least switching to 24h time to prevent the M from burning in. back to topic, there is nothing magic about it for battery drain though. You can do alright if you always work in black background screens, but in many cases you are doing worse than an LCD. Don't expect more than 2.5 hours of active use in the best circumstance if you leave it at 100%.

(note GOS since this is propaganda, but the chart is interesting. It implies that our screens burn up to 1.13 watts when full white, which can be 50% or so higher than similar displays. It also contradicts my statement that black pixels are always on)
Apologies again for straying from topic. The display was the main factor that made me pick Samsung, and yes I do like it.
Swyped w/ XDA App. When in doubt, mumble.

51% at Noon after moderate use, did a nandroid back up and flashed a theme as well. Theme I flashed is pretty dark and high contrast, so I'm gonna tone down the screen to zero percent, charge it back to 100% and see what the rest of the day is like. Also have had GPS and Sync on at all times as well, going to try it without those for the rest of the day as well.
Do you guys use auto sync and background data? I don't think I really need them, I don't really care about my facebook push notifications, but do care about email...

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.

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!!

Help, my battery life sucks!

Hi,
I unplugged my phone this morning around 9 A.M, and sent about 50-100 texts today, and right now at 5:35 my phone is at 33%. The only thing that is running, is ADW.Launcher, and I've done LIGHT Twitter/Facebook checking throughout the day, maybe about 2-3 times each. I have Beautiful Widgets, but it's set to update every hour. I haven't talked on the phone at all, and my brightness is set to auto. My wifi is off, and I made sure I don't have GPS or anything on. What's killing my battery? My BB's battery life was 1000x better, I shouldn't have to baby this phone to have it make it through the day.
I'm running JT's Clean D101 rom, and that's it.
Edit - 32% now.
Get "OSMonitor" from the market (its free) and it will give you a real time display of all running processes and cpu % for each process. To make it easier to watch list open options in OSMonitor and sort by load and make sure order is checked as well. And watch the list for a couple of minutes to see the offender that is hogging the cpu. I've had problems with the xda app and I seem to be the only one that has it hammer the cpu after closing it so I always have to kill the xda app in task manager after using it or else it will ride the cpu between 8-20%.
My typical idle cpu usage is about 2-5% not including the cpu usage of OSMonitor itself.
good day.

Thats about normal time for a Smartphone. If you average that you used 66% of your battery in 8.5 hours, then its safe to say your battery is averaging 12 hours a day. Also, most of your battery will go to your display, and if you texting all morning, your display is going to be on all morning.
It also could be that your in an area with bad signal. Your phone is going to pump juice to try and keep signal.
As far as BlackBerry gos, its not nearly as smooth and capable. I could argue my flip phone from high school lasted four days without needing to be charged. Android is in an entirely different class than BlackBerry.
Is there a definitive process for conditioning or reconditioning the stock battery? I'm on my second fascinate(vzw replaced first one basically because of my frustration with the local vzw store) & I've noticed a big difference in battery life between the 2. First one was completely stock with adw launcher only & it got 16-20 hrs between charges. This one is rooted, some bloat removed, and I only get 8-10 hrs. Using os monitor to look for cpu hogs & so far no improvement. Put all my bloat file extensions back to stock in sys/app hoping to impact erratic charging cause it all started after root. Any ideas?

I'm no expert (standard disclaimer) but I don't think it's a matter of calibrating the battery as much as calibrating the software.
Power the phone down
Charge to 100%
Boot into CWM
Wipe Cache
Go into Advanced, and Wipe Battery Stats
Pull the battery, reinsert, and again charge until have 100%
Unplug, reboot, and run the phone in whatever your normal use is until you get as close as you can to a full discharge
Again power down and charge to full
As I understand it, this process allows the software to correctly read the true charge on the battery. if anyone sees any flaws with this, or anything incorrect in my information, please advise.
Are you using a Live wallpaper? I noticed an increase in my battery life after I turned it off, which is kind of stupid because it should only use CPU cycles when the screen is turned on.

This could be a big offender right here. Use the power control widget and keep it on the lowest brightness except for when you're in areas that make the screen too dim to make out (read: outside).
Thanks to Daswolven. Recalibrating the battery did the trick. The only thing I can link the issue to is having to charge from my laptop for 3 days last week due to a massive power outage in my area. Anyone else see this?

[Q] Best battery life Rom?

What is the best rom for the Epic that will improve battery life? I have an Evo. My wife has an Epic. Mine will go all day and end up at 45-50%. Hers will end up at 15-20%. I know that 2.2 will make some great changes to the battery life (God I hope so), but what choices do we have now?
Epic Experience with Phoenix kernel gives me a good 14-18 hours with medium usage.
Rims don't change anything really battery related. Kernels are what effect battery life.
Also, you don't need a specific kernel to get amazing battery life. Get these apps
Spare parts
Autostarts
Juicedefender ultimate
Spare parts will tell you what is killing the battery
Autostarts will disable the drm crap on startup
Juicedefender will disable the data and wifi when not needed.
I can get 24 hours on my epic without even trying to conserve battery.

Speed freak and in desperate need of good battery life are polar opposites of each other. Nothing the phone does at this point needs the processor to be clocked any higher than stock and doing so is detrimental to battery life. The phone is plenty speedy using that combo. You might get the occasional hiccup in a menu for a half a second, but it is worth it for the amazing battery life, and it isn't a big deal at all.
yeah i realize they are complete opposite. im just trying to find a good balance between battery life and power. i may just have to sacrifice a little power for battery life then. i will try this combo maybe tomorrow, seeing as though i have homecoming tonight lol.
i get 60 hours + with moderate usuage. andromeda rom which includes andromeda kernal. You do not need spare parts or any task killers. 24 hours is weak battery llife. phone calls is the most extensive battery drain. if i do not make a call i can browse all day and still have 40% left.
This is how you get amazing battery performance.
I have some very VERY helpful hints of great battery life for the Epic 4g. (as i am on hour 26 to 28 and have 20% left with about 1 to 1.5 hours of screen on use.)
First off, use black, or almost black background. Our screens are superAMOLED. This means that if the screen is showing black... those particular black pixels... are simply not on. If you have the home screen black, and have no icons on it, then the status bar is all that is using power... maybe 6 or 8 percent.
Next, Lose the brightness. A few helpful hints on this. 1) uncheck the autobrightness in the display settings 2) turn the brightness down in the display settings 3) If you slide your finger from right to left across the status bar at the top, the screen will dim, if you slide your finger from left to right, it will brighten(this causes accidental brightness 4) cover this light sensor on the right side at the top (I believe) because the phone seems to have a problem always autobrighting even with the uncheck in the settings. This is done best with electrical tape, or perhaps finger nail polish. These things should ensure to always be at minimum brightness
Next, Install Frankenstein Froyo Rom(lightest rom=less cpu usage/blackest rom=less screen battery usage), And Genocide Kernel(undervolted)
Next, install task killer(keeps the rom at optimum efficiency meaning less cpu usage assuming you are killing the apps 3 or 4 times a day) install set cpu(This allows you to limit the cpu clock speed(400mhz is optimal usable and battery settings)
Things to remember, ALWAYS TURN THE SCREEN OFF.
If you pick it up every thirty seconds to see if you have a text, then just sit it down... whats happening now.. The screen is staying on for another 15 seconds probably. DUH!!! bye bye battery!!
TURN OFF THE SCREEN BEFORE YOU SIT THE PHONE DOWN!!!
Turn off gps when not in use.
Turn off wifi when not in use.
Turn off 4g when not in use
Dont use it as an mp3 player.
Dont talk on speaker phone.
Those last few were pretty obvious.. but some people need to be told.
I Hope this helps anyone looking to conserve battery. Follow these steps and i promise 24 hours plus ever time and often as much as 48 hours.
Enjoy
EDIT****
By the way, When you set yourself up with this rom, you are making your phone TWICE as fast... LITERALLY. Hard to believe that a ROM could be twice as fast.
With stock android2.1 this phone gets 800 to 900 in quadrant(benchmark tool/tell how fast your phone REALLY is) Stock android 2.2 quadrant score is a little better scoring as high as 1000.
With this setup, i have gotten as high as 1950 in quadrant. No joke. This is reflected as you cant even tell the phone is clocked down to 400mhz without heavy apps and REALLY paying attention.

SyndicateROM Frozen (EB13) - Battery Life Thread

Hey guys,
Just created this thread so we could all have our battery life info in once place and keep the dev thread from getting cluttered.
Please post the following info:
1. Standard or Fully Loaded version
2. Total hours unplugged and percentage
3. Details (percentage and time) for each service
4. And any pertinent details such as apps used (juice defender), or extended batterys
Also, please don't forget to calibrate, airplane bug fix, and kill that drm.
Ex. (will edit with final time)
1. Loaded
2. Total - 8h50m @66%
3.
Display - 55m 78%
Cell standby - 8h50m 9%
Wifi - 6h40m 7%
Phone idle - 7h54m 4%
Voice - 1m 3%
4. Juice defender, setcpu @ 100/1000
Ideally we want to wait for a full drain to post stats but this is just an example. Thx guys looking forward to seeing what you all are getting.
Just installed it will get back to you in a couple of days after recalibrating my battery.
Btw, i hear Juice defender does more harm than good...

Interesting. I think you are right, we are essentialy minimizing out idle drain to a certain extent. However, even activily using my phone it drans slower than stock with this rom. My next run ill try and use it all day to see what I get.

Battery drain
Hello everyone, noob here. I can't post in the development forum on this but it pertains to the battery and charge to a degree. Maybe someone here can help me in some sort of way.
I rooted and flashed the SyndicateROM Frozen yesterday, used it all day and never a hiccup. This thing is lightning fast and props to the dev's but here is the only issue I found. This morning after waking up I noticed the phone was stuck on the ACS android startup icon. I plugged in to charge last night and it's like it froze the phone when it reached full charge. Anyone else experience this?
Thanks for any help that I receive.

I think I read in the dev thread that it's a known problem with the kernel? Or maybe it was the rom... or CWM? anyways the dev's know about it. Just don't charge your phone when it's off.
Battery for me seems to be a lot better than stock, but I'm always charging here and there... today I'll let it run without charging for 4-5 hours and I'll report back. Using a lot of setCPU profiles.

This morning after waking up I noticed the phone was stuck on the ACS android startup icon. I plugged in to charge last night and it's like it froze the phone when it reached full charge. Anyone else experience this?
Thanks for any help that I receive.

Are you charging it with the power OFF? Lots of people were posting issues of freezing when charging with the battery off --- and I think the probs are related to CWM -- not the ROM. Only charge while the phone is on -- and you should not see problems.
I put on to charge with the power on last night because I had set the alarm to wake me up and it never did so that is when I noticed it. I don't think I've ever charged it with the power off, even when it was stock.
Maybe the dev's will come up with a fix sometime in the future. As for now, I'm happy as hell 'cause this ROM is great.

Did this just happen once? If it doesn't happen over and over, I wouldn't consider it a bug. I have only heard of issues like you describe with the power off.
I'm looking at 12 hours on ACS Frozen on average. I haven't even gotten close to the rumored 30 hours with "heavy use" I think my use has been moderate. My battery use log only only lists display 98% and cell standby 2%. This confuses me. I do more than sit there staring at my homescreen.

How you use your phone makes a difference and while 30h is possible, I don't see it happening with heavy use unless that is little display use. Below is my most recent "heavy use" run. Basically tried to use the phone all day, xda app, browsing, mainly wifi, 0% screen brightness.
1. Loaded
2. 8h7m @5%
3.
Display - 5h33m 95% <- serious display use which kills the phone quick
Wifi - 4h56m 2%
Cell standby - 8h7m 2%
Voice - 4m30s 2%
4. Setcpu @100/1000, juicedefender, 0% brightness
Pretty good considering the insane display usage. With normal use I get over 20h so that just shows how fast it kills your battery. Going to do an "extreme" run next to include heavy cpu use (play emulators all day haha).

You did that with a standard battery? I haven't seen anyone post more than 4 hours of display "time on". That's impressive. Maybe I should try 0% brightness. I have mine at 25%. Are you on "Conservative" on SetCPU?

The 98% means that 98% of your battery use is coming from the screen. Click on where is says 98% and look at see what the use details are (the "time on"). Generally, most people are getting less than 4 hours of display time on with a single charge. The explanation is that some people stretch 4 hours of display time over 30 hours of use. In other words, the people who are getting 30 hours of use only have their screen on 10 - 15% of the time (or less).

Yes, using the standard battery. Setcpu is on conservative. I always use 0% as it looks great (kick it up tp 25-50% outside). I think I was able to get that long of display use due to minimizing cpu usage and other services. All I did is browse in dolphin and use xda app. And, that was pretty much all on wifi. Only change was the hour I was at the dog park on 3g and I recorded a 5 min video.
I bet my gaming session tomorrow will kick it down to ~4 hours
With phone calls, texting, and music player, I average between 16-18hrs. If I start to web browse or watch videos then about 8-12hrs. Very impressed with this ROM to say the least.
1. Standard
2. 31 @ 5%
3. don't have that it was yesterday
4. standard battery, auto brightness, overclocked to 1.2, wifi on when I was at home and 3g at work.
I calibrated the day after froyo dropped. I didn't do the airplane thing and I thought drm was not in this rom. So in other words I didn't do any fancy stuff.
I will note today I tried 1ghz (which is undervolted) with 4G on all day (I have a repeter on my roof at work) and after 14.5 hours I am at 30% with about the same concistancy of usage as yesterday.
Edit: I only have 1 gmail syncing right now. We will see if I get these magical numbers when I put my other 2 gmail accounts and my 3 actice sync exchange accounts on Monday.

I'm getting mixed battery life. The first day on the rom/kernel I dropped down to 79% in 9 hours, with medium use (no web browsing). I was getting 1% drop every 1-2hrs, and thought it was amazing. Today I tried to be really conservative and didn't use it at all and it dropped 4-5% every hour WHILE IDLE.
Anyone else experiencing the same problem? It seems to happen after a reboot to be honest.
NOTE: If I disable data network mode, battery life is amazing,
I'm not sure about my battery life. I charge mine differently than the average person though. I charge it at work and leave it in my desk, because I use it a lot during my lunch break or whenever I get any downtime. When I get home it's usually at about 70%, and it remains unplugged until the next day. I used to have to charge it at home and at work.

Bi-Winning v3.0 + Bali v1.8.8UV = 48 hour battery

I thought I would throw this out there just because I found it quite amazing after a year of tweaking the vibrant. I just decided to swap back from Simply Honey to a 2.2x rom because I was having issues with reboots while on the phone. I had been using Bi-Winning prior to installing SH-3.9 so I went back to that but this time I installed the Bali v1.8.8UV kernel after reading some tips. I'm getting 48 hour battery life on moderate use where I was getting 18-20 before. This Bali kernel is something else. I think this setup is a keeper.
you just put on bi-winning and bali or did you undervolt as well? settings would be great cause with a 48 hour battery thats enough to get me to go back to froyo haha especially now that netflix is on froyo as well

I just put bi-winning on it, rebooted, put bali on it. I'm trying to think of anything else I did but I can't. I installed this combo friday night and I thought it was a fluke or I had forgot that I had plugged it up sometime over the weekend when I woke up monday morning with 25% battery. I made it from tuesday morning @ 7:00 until just now with 40% left. I Just plugged it up and I'm going to make an effort to actually benchmark it this time as I don't believe it either. I also just put the same combo on my wife's vibrant to see what kind of resultes it gets.
Am I subconsciously plugging my phone into the charger?
Yep, I get similar results. Currently I'm on ZenDroid 2.0.1 with Bali 1.8.8UV and I'm sitting at 35% remaining and 48 hours since unplugged. Light-moderate use I guess but with some gaming, lots of texts, several 15-20min calls, and wifi on 24/7.
ECOTOX's DragonMODz ULP kernel performs very much the same as well. I have a hard time picking between the two.

wow thats awesome, just checked out bi-winning and there are some decent themes as well. So this is with data and sync on as well?
I'm currently running on Asgard 3.1.2 (Same devs, right?) and it's running awesome.
Thought I'd upgrade to Bi-Winning 3.0 on my Vibrant.
I'm kind of new to this.. so since I'm on Asgard running the Bullet Kernel, all I have to do is flash Bi-Winning via. Odin3, right? If so, will I lose any of my apps/data?

Indeed. Full Google account sync and Facebook once daily. Data is on and using KB5 modem.
Oh and I've also started using the Screen Filter app to reduce screen brightness even more than the android minimum and it seems to be helping a lot as well. Check it out.

Just wanted to add a testimonial to the OP since I'm running exactly the same thing. Just Bi-Winning and Bali 1.8.8UV, it already comes undervolted by -25 I believe and I'm getting similar results on battery life. Kernel and ROM go very well together and it's quick, responsive and very very smooth. I'm using it with ADW EX launcher by the way.
flashed both and so far so good, battery is a little better but nothing as significant as 48 hours, do I have to wait a day or 2 to let it settle in first? Cause I know when i was on cm7 they said let bali run for a day or 2 then after that youll notice the difference
No pics, no proof
Anyone of yall use GPS at all or just moderate use....
The stock battery will not last with more than 2.5 hours (+/-) of Display use, no matter how you slice it.

Well, that's just plain wrong. I've been gaming through multiple episodes of "The Good Wife" with my family and my battery is down maybe 20%.
Now, 2 1/2 hours of an all white background on maximum brightness might kill your battery (flashlight apps), but not typical use.

I don't know exactly what "gaming through multiple episodes" means but a screen is a screen. There's no software affects the display's energy use. Like I said, the +/- depends on your brightness settings and exactly what you display on your screen. I challenge you to show me battery usage screen shot with more than 2.5 hr of display on time on a single charge (with stock battery). I don't doubt you can push 48hrs on a single charge, but chances are, the display on time is less than 3 hours
Does anybody have some screenies to prove it?

I have the exact same setup and my battery life is nowhere near as good. And this is just with data on, no bluetooth, wifi, gps, sync, etc.
Echoing the sentiments of others... Seeing is believing screen shots guys. Thanks

Well, you're in luck! I'm breaking in a new 1700mah battery and want to drain it down to 20% anyway. I'll do so with the screen on my default homepage instead of using the flashlight app. I'll run a stopwatch app in the background and get you some numbers. If you're right, I'll eat my hat!
Then again, since you said +/-, even if it lasts 72 hours, you're still right. It's just 2.5hrs +/- 69.5 hours
I'm the OP and for the last two days my battery has not been lasting nearly as long. Of course I have gone for light/moderate use to heavy use but also I'm seeing it chew through more battery when idle. I'm not sure what has changed to make this happen. I've kept wifi off. I don't think this had anything to do with it but it seemed to start using more battery as soon as I installed the google maps update but the battery profiler doesn't say anything about maps. Oh well...
Well, after 2hr30min, my battery is at 84%. Sure, it's a new battery, and the 84% is probably a little inaccurate, but I haven't stopped the test, so we'll see where it goes from there. Wifi, Bluetooth, and Data are on as well as several widgets on my homepage. I haven't done much with it except keep the screen on indefinitely and send/receive a few texts.
Anyway, the proof is in the pudding. Mmm... pudding...
