Finally did the OTA update... crazy good battery? - HTC EVO 3D

Hey guys... I finally updated my E3D with that update. My sister and dad both updated theirs when they first got it.
I'm getting really good battery life. Minimal usage yesterday, but after 16+ hours I still had more than 60%... I even played a little N64oid.
However, my sister and my dad both get pretty bad - decent battery life. My dad doesn't use the phone nearly as much as me.
I wish I knew what settings are doing it. We all have the same settings but my idle time loses me like 2-3%/hr but for them it can be up to 7-10%/hr.
Anyone in a household with more than a couple E3D's getting this varied battery life?
Settings are virtually the same, and location isn't a big factor either.

A lot of things impact battery. If the settings are the same across all phones perhaps the drain is app related. If you really want to test you should factory reset all phones and then check. This way all truly have same settings and apps. I would bet at that point they all drain the same.

I did the OTA and my battery life shot up instantly.
Before the OTA I would have around 15 hours of light to moderate use of text, calls, and browsing before it hit 50 percent. Now, I would basically do the same things but I can go a full day before it hits 70 percent.

I bet you they use the phone more...calls..facebook....etc..friend of mine gets couple hours...and he plays games non stop.

Battery Life

My battery life seems far too short. If I remove my phone from charge at 6am it's got very little life left by 10pm. 16 hours is pretty poor... No WiFi or BT, but I do have reasonably high usage of around 15-20% perhaps.
I did read something about Quick Calendar being a bit of a drain, but I really like this widget, so I don't really want to lose it.
I don't have all that many apps installed, maybe 10-15. How does this battery life compare to everyone elses? Is there anything I can do to extend it?
mine last about the same. I am using the internet alot & widgets like twitter & flickr as well as watching films/listening to music. To be honest I think that this battery is pretty good seeing as how much I use.
When I compare this to my Diamond which i was using a lil bit less by way of features I am truly impressed with the stamina they have given to the stock battery.
That being said if they ever release an extended battery I will be buying that in a heart beat
Generally I think it has decent battery life, but its changeable. Sometimes I wake up in the morning and the battery has drained overnight from nearly full to totally empty, but sometimes there is no indicated overnight drain based on the battery meter.
I think the battery meter is probably about as accurate as the one on my Diamond (ie not accurate at all)! I get the same battery life from my Hero if not more as I did on my Diamond with the extended battery which considering I do a lot more with my Hero is impressive.
I think the battery is pretty good considering all it's doing.
When I have it on, playing mp3s and HSDPA and wifi all day, I'm lucky to get 12 hours. I mean literally MP3s all day though, and since I'm at work having a usb cable into my laptop isn't a big problem, which removes the battery problem.
Today I've had limited internet use (mostly just 2g email polling, with about 30 minutes of whatever 3g exists in the bowels of wiltshire) and, as I've just noticed about 3 hours of GPS. It says it's used about a quarter of it's battery. Used as a simple phone, I'm sure it would last more than 3 days, but why bother?. As a pure email device, maybe just under 2, and as an always racing internet/music/gps beasty 1 day.
I'm happy with it.
Have you tried intstalling taskiller to get rid of those apps using power in the background?
My battery life is terrible. I fully charged my hero and unpluged it 8 hours ago. Since then i've made 10 minutes of calls, around 45 minutes of browsing (with 15 minutes using wifi), and 'played' about with it for around 30 minutes. My battery is down to 20%. I don't think this is good at all because i haven't used it that much.
edit: I also use taskiller to close apps after im finished with them.
Yeah, I use taskiller, nice app. I've also installed something called Power Manager v1.5.9 but I'm not really sure how it helps... if it does...
Woah I started doing a Battery Saving /Speed up Tips thread last night - Just posted it - Any good stuff post on there... Plus there might be stuff you've not done yet (Tho its pretty straightforward stuff that I reckon you'll have done already Ya never know tho)
Dayz xx
I found the first 3 charges only gave me a day (but this was when hammering the phone for the first few days), after the 4th charge and dropping to my normal useage i get 2 - 3 days, which is just better than my Tytn2.
I use my hero as my works phone and make about 40 minutes of phone calls on a 12 hour shift, it also picks up my emails and does about 30 minutes of browsing during that time, and by the time i get home it has about 30% of battery left which isn't too bad, and is much better than my diamond.
Things seem to be improving for me too now. Also, I took of Quick Calendar which people were suggesting was eating battery...

Sprint Hero battery life

I'm fairly disappointed in this battery and will start gathering benchmark metrics,asking others to do the same for more data points and what does and doesnt work to increase.
Currently I have disabled sense ui and reduced widgets down to hardly anything, just a search and taskiller. I seem to get around 10 hours with moderate usage (occasional short call, several texts and quick searches, etc) letting android download background data and check google accounts email, contacts and calendar (this really is the power of the phone, cloud syncing pim). Weather, stocks and other "widgetable" apps are refreshed only on demand.
It's worse than I thought. I went less than 6 hours today with only one quick call (<1 minute) a few youtube clips and 2 texts. I noticed the phone was pretty warm in my pocket compared to my HTC touch (it actually felt cold sometimes if left on the desk) and a few times I noticed that there would be no radio "bars" but most of the time I had 3-4 out of 5 bars (I never have recetpion problems where I am) leading me to believe that something goofy is going on with the radio. I am going to reset since my testing is over today!!

Whit what tool did you test it?
It's still to early to tell but I'm seeing decent battery life. Better than my pre but not great. Certainly acceptable considering I'm playing with it all the time since its new.
i also am seeing bad battery life.. i had court yesterday, and had it OFF most of the day.. and it was dead last night, i turned it on after court.
anyone notice this:
the website has extra batteries
http://nextelonline.nextel.com/NASA...oryID=BSH5110&topPageNumber=0&subPageNumber=0
they say 1340mAh. mine says 1500mAh
do you guys think thats a mistake?

I just looked at battery usage in Spare Parts at various parts of the day and input this manually to minitab. No special app or anything.

I read that the European version has a small battery, but because it is GSM is supposed to have as good or better battery life than the CDMA version.
The GSM Hero has a 1350mAh battery, and battery life is reportedly slightly better than the Sprint Hero even with its more capacious battery. As you correctly surmise, this is due to the Sprint being a CDMA network.
Why Sprint would want to sell a lower capacity battery though, I've no idea!

Dave
my battery didn't last a full day either
I am into my 3rd day of usage (on single charge) on my week old hero.
Running on 2G network, turning off all data connectivity, manual reduce screen brightness, minimum vibrate and sound notifications for typing and applications
I have a Sprint Hero and the battery is at half strength not too long after lunch. But since I've only had the phone 3 days, I probably am playing with it more than usual. I'm guessing Seido will come out with an extended life, same size battery. They did with my Touch and it was great! It was very handy having a spare battery when I was out for a long period of time, away from anywhere to charge the phone.
Im also into my 3rd day of usage, and been off the charger all day today... had a couple calls, couple texts, bout 3hrs worth of browsing/facebook/twitter... down to about 60% as we speak so i know its a vast improvement from my tp... hell, 2 hrs of anything on that phone and it would be below 50 percent before the day even really started lol...
There are a number of things you can do to help improve battery life.
1 ) Turn off Wifi autodiscovery. You can always turn it on again if you are at a spot where you know you have a good wifi connection and plan on using it. My Hero was constantly telling me about wifi hotspots that I was driving past. I've found a number of widgets that will turn wifi on with one push.
2 ) Set Twitter, Facebook, and or email to check for updates less often than stock. I don't remember exactly what mine was set to at the beginning, but one of the first things I did was set Twitter to every four hours and Facebook to every two hours.
3 ) GPS is also a battery eater. Turn it off unless you need it.
4 ) Whenever you get a new phone, you ( well, I do, I'm just assuming that you do, too. ) use the heck out of it, playing with settings, seeing what all the programs do, downloading apps and games. Battery life should pick up as the newness wears off.
If you guys want a little more juice, Seidio just came out with a 1750mAh battery that fits in your device's existing battery space and doesn't require a replacement door.

Problem is, whats the point of having a phone designed to have al lthese features if you can't use them as the battery just dies.
My T-Mobile G2 / Hero dies so quick it's annoying.
Yes I've been doing lots of stuff with it this week but to have to turn of 3G to save battery is a laugh. My old Sony phone uses 3G etc and it can last a good two days without charge.
I've kept my 3G on but have kept all the updates to minimum amounts or to be done manually.
Background data also turned off most of the time but again, if it's required, then we shouldn't have to turn off.
It's about time batteries were developed or the companies actually provide longer life ones.
All the testers reviewes keep going on about how great the battery life is doing all these things and stuff, what batteries have they been given to use compared to the rest of us I wonder?

[Q] Is the TB battery life as bad as it seems?

I just bought a Droid X2, but have decided to take it back for an LTE phone before the change in unlimited data.
I really don't like the way the charge looks, but it seems to be just as good as the TB. The TB has the likely potential to have a better community and better roms.
However I cannot have a phone that cant hold a charge for a whole day. And I do keep my phones for the 2 year duration of the contract, so whatever I get I need to be happy with.
I get the idea that the TB lasts between 4 and 8 hours. Is this a hardware issue, or is it the ROM which would be fixed as time progresses?
It is pretty bad. If you live in a 4G area, you should get the extended battery.
There are some settings tweaks, especially in the stock ROM, that help tremendously. The notification/background data is what kills the battery.
I always get at least 8 hrs with normal to heavy use.
But if your streaming video constantly, yeah like 4 hrs.
Most I have seen is around 20 hrs.
Seems like it always dies with about 4 hours of awake time or actual usage.
In a 4G area. And I think it will get better with hopefully a new OTA.

If you are going to play with ROM's, standard battery life is real bad. I loose about 25% of the battery, 4G downloading, then flashing 1 ROM!
Add 2 hours worth of on anf off fiddling with the screens and setups takes it down to 40% remaining, then I have to turn off wifi, and 4G to get through the workday, ending <10%. If I do 2 ROM's, i'm dead before lunch. Gotta get a cable for work.
Get the extended battery. Mine lasts typically a day and a half with it, moderate usage. Awesome phone.

I can get a full day out of my phone with moderate use (texting, calls, web browsing). I have my settings tweaked and have juice defender running which really helps. I'm on stock ROM and am not rooted, there is a lot you can do to improve the battery.
Well if you use your phone as much as I do then you would be surprised how quickly the Barry drains out haha
Sent from my TB yo.
Mine is usually 60-85% display, and I have it on dead minimum brightness unless I'm outside in the sun, in which case I set it to auto for a few minutes. Mind you, that's maybe five or ten minutes max of screen on time, two or three times a week. On the other hand, a twenty or thirty minute phone call can take ten percent off; I'm one of the people who sometimes remembers that it can make calls, too, so my experience is probably a bit off. I also have most everything set to sync every 2 hours, but I have imo.im running constantly.
If I'm using it pretty heavily, it may be down to 40-60% on the standard battery by lunch, which would be about three or four hours of screen on time. I'm in a 3G area, btw. I just carry a charger; which has the advantage of making other microUSB people happy when their phones die (and we can mock the iPeople with proprietary chargers). Yes, the battery sucks, but every phone has trade-offs.
If you won't have any way to charge the phone (car, wall, etc) during the day, then I don't think you will be happy with the phone. Between my wall charger (or USB cable), car charger, and two batteries (spare is the Seidio 1600 mAh), I'm satisfied.
As for the Droid Charge, the Touchwiz UI compared to Sense is a non-starter.
Is it bad? Yeah, seems like. Is it as bad as everyone is making it out to be? I dunno. I remember a lot of people complaining about the battery when I got the Incredible. With light use (about an hour of internet and email over 3G, one or two half hour calls, and a handful of texts), I'd charge it every other night (and have 30% or so when it went on the charger).
I picked up the Thunderbolt yesterday and charged it overnight. It came off the charger at 7:30 this morning, and I'm showing 54% as I'm typing this at 8:45pm. Since it's new, I was probably fiddling with it more than usual (but not a ton more, as the differences between the Thunderbolt and the Incredible aren't huge).
So with 4G on, yeah, it runs it's battery down faster than my old Incredible. But it seems like I can make it through a day without much difficulty.
EDIT: I figure I might as well mention my settings.
I have the brightness set to about 30%. I shut off any and all vibration. Screen timeout is 1 minute, volume is maxed for everything. Bluetooth and GPS are off (unless I need them). The weather widget updates every three hours. I don't use any other widgets that use data (just a volume profile and a power control widget). The phone can do background sync for my contacts, but my gmail, other mail, and Twitter (Seesmic) are all set to update manually.
I'm getting about 8 hours of moderate usage here as well. I've come to terms with the fact that using a device that is more powerful than my netbook will come with some battery trade-offs.
hey guys,
I'm going to follow this thread for a bit. My HD2 jumped into the Harbor yesterday and will probably be switching to Verizon for my next phone. I'd really like to get the TB, but am really concerned about battery life.
It sounds like people are getting a battery life similar to what I was getting running Gingerbread off the SD card on my HD2...which didn't quite cut it for me on days I was working in the field and not able to charge. But at least with the HD2 I could run WinMo on days like that and not have worry.
Keep the info coming!
thanks

Hello, im currently running with juice defender, but i was wondering if you could help me with what all settings i should tweak to help the battery?
After applying the MR1 OTA update I still wasn't happy with my battery or GPS performance, especially compared to my past phones (Incredible, X, original droid, blackberries, etc)...
After doing a wipe and reloading the apps I use by hand, I have seen battery life match the Inc in 3g only areas, and GPS lock on my location consistently in under 7 seconds.
In mixed 3g/4g areas (where I live), similar results. Battery life and GPS lock are very much improved. And the TB now makes it through the day for me.
In solid 4g areas, well, last night I was surfing the web, reading, looking to see if the GB update for the X had hit. I went to bed around 1 am with 80% battery, didn't hook to charger. This morning at 9 when I looked it had received some emails and auto updated some apps.. battery was at 55% so that is better.
It's still not as good as my droid x, but the TB is certainly more usable than when I first got it a month and a half or two months ago.
The t-bolt is better than my inc was, with bams GB rom I got 12 hours of heavy use with stock battery....my 2 cents...
I just tested my battery life. It was about 2 hours with Carl pagan cosmos on 2g. 4g really eats the battery. After I recharge, I'm going try it over 3g and see if that makes any huge differences.

[Q] Battery life

Well, this question is for my lucky friends who have their new toys
Battery life is so good?
Post your test here!
Don't have screens for ya but battery life is more than adequate. My gf and I used it for about 5 hrs last night and it dropped to about 45%
(Games, xda, Netflix, and just tinkering around)
I'm curious what kind of battery life you folks are seeing, now that you all have had time to get some real world experience with the NT.
Thanks!
10 hours of continuous usage with 25% brightness.

Yea, the battery life and responsiveness of the device is definitely top notch.
I'm pissed as hell the bootloader is locked, but this device is an absolute steal for $250 bucks. Especially if you can manage to discount that price down.
Extremely responsive and awesome battery life considering I'm running max brightness and wifi 24/7.
I'm always surprised when I'm done using the Nook that it was still running. Granted, I ran it until it had only had around 20% left. But hey, if your sitting in one spot using your nook for more than ten hours, then you need to find something else to do. ^_^

Good book, nice day, under a tree? Done that many times just reading off my PDA.
Thanks for the feedback!
The battery life is definitely adequate.
I can usually go 2 day without charging thus far. I keep brightness at ~20% or so (I can't stand brighter, it actually bothers my eyes).
I also use multi-picture-live-wallpaper and it doesn't seem to drain my battery at all.
I do some pretty heavy use of it as I am reading on it and studying for med school for probably ~6 hours at a time
Battery life is great. BN's numbers seem dead on.
Lasted the flight from San Francisco to Sydney
I'm getting around 10 or so hours of use at 2/3 brightness. Battery life is amazing on this. I charged it last night. Took it off the charger at 10am didn't touch it till 10pm tonight. It was at 99 percent then. I think it turns off wifi when it's sleeping.

Yeah, it definitely turns wifi off on its own when sleeping
Yeah Ill echo the comments here, battery life is absolutely superb and the responsiveness of the unit for the price is fantastic. Sadly its a case of if only B&N....to fully realize what the tablet would be capable of.
I have to agree that battery life is amazing on this thing.
I've got wifi turned off full time (to avoid updates from B&N) and the battery just seems to last forever. Granted you always use less battery when you're not going online, but still, it seems to really really last.
Frankly it's making my phone quite jealous.
Umm, my nt's battery isn't as impressive as i hoped. I use 25% brightness, wifi on, no fancy live wallpaper. I noticed for every few minutes of sjurfing, battery would drop a percentage or so. For usage of about 3hr withoit wifi, i would use up about 40 %.
Anything i could do to tune it up a bit? I do noticed amazon appstore is always running, so is clock, contact, tb, and my yahoo mail app. Any help is appreciated.

That sounds about what I'm getting and I'm wondering whether it's defective or not (still within return window).
edit: Probably normal - ran into some threads on B&N's boards where other people are averaging 5-7 hours. If I idle / read, I get about 1% every 8-10minutes or so so B&N's time estimates were definitely not "video," "browsing" or "games." Wifi on, installing or rebooting a few times, it drops to 5-6 hours tops between 100% and close to 0%.
My phone gets -way- more time, even reading.
the battery on this is great one of the biggest things going for it. better than my phone for sure.
For you guys with bad battery life, you might want to try better battery stats. Then check for partial wakelocks. That's usually the culprit on my phone. It seems weird some of you are getting half the battery life of the rest of us. Personally I haven't even turned wifi off at all, and also haven't turned my brightness below half.
It's in the google market, it won't show up on the nook. I downloaded it on my phone then used the app share my applications then back up to sd. Upload to dropbox. Then download it with dropbox on your nook.

I looked at this (and other battery programs), but wasn't sure what they did. Now I sort of do. I'll check it out! Wifi on definitely uses up at least 20-25%ish extra battery, and I *have* been moving a ton of stuff to/from sd cards and uninstalling and rebooting a lot, but the above did seem very short. Too bad there isn't a battery hardware test
Failing those applications it may be worth doing a full reset; Especially since most other owners are reporting MUCH better results.
Before I start nuking things around, I used BetterBatteryStats, check for partial wakelocks, and the highest % is from ActivityManager-Launch, which occupies 0.3% or 5minutes or so since I fully charged it.
Also, i noticed "Wifi Locked" is extremely high, like 89%, whereas wifi On is only 26%. What does that mean?
I'm not fully versed in how Android handles power management. So what should i be looking out for? Thanks!

Side by Side battery comparison - CleanRom 1.6.5 SP1

First of all, let me say thanks to Scott for all of his work on CleanRom. I know there has been a lot of discussion lately in his thread about battery usage. Some people are getting outstanding battery life and some people can't make it more than a few hours. I have been one of the people that can't make it more than a few hours no matter what I do. I did a clean wipe of everything before installing the ROM and have even tried to reinstall. The odd thing is my wife's phone does fantastic with this ROM. I finally decided to test things side by side lastnight. My phone should have had the clear advantage because I turned off all syncing options and froze any apps that had been downloaded just to make sure there was nothing running. Meanwhile, her phone syncs like crazy to facebook, email, etc and also has various apps running like weatherbug. I let them both sit overnight and after ~9hrs here are the stats I measured:
Battery % left : 79% (mine) vs 88% (hers)
Data used overnight: 75kb (mine) vs 744kb (hers)
Time awake: 3min 32sec (mine) vs 9 min 42sec (hers)
Time in Deep Sleep: 9hr 19mins (mine) vs 9hr 6min (hers)
Everything points to the fact that I should easily have more life left than hers. I am also attaching a couple of screenshots and the betterbatterystats files to this post. Maybe we can track down why everyone's battery life is so different. Tonight I plan to swap batterys between the phones to try to determine if my battery is the problem.
wow that's pretty good on your wife's phone but horrible for yours especially considering you turned off syncing.
I agree. I have no doubt that her phone could easily still be at 95% or more if I made all of the same adjustments to hers as I did to mine. That is why I am hoping someone on here with more knowledge about this stuff can help to determine what is going on.
It honestly might just be a faulty battery, I was having similar results with mine and my friend's phone, too. I tried multiple ROMs, Kernels, etc. But it slowly got worse and worse to the point that I would go down from 100% to 60% in little over an hour, doing nothing but listening to music with the screen off and auto-sync etc off. I bought a replacement battery, though. And this one is working just fine. You might just be having bad battery luck, or it might be your device, I know some people have returned their Rezounds because of battery life/heat problems, and the replacement generally fixes their woes.
so what did your betterybattery stats report?
Thanks for running this test. It would be very helpful to everyone if you could pinpoint this to a battery difference and I'm waiting to hear your results after the battery swap.
What helped my battery life most was to uncheck the box under "settings -> applications -> start automatically" It has something to do with a task manager. It probably wouldn't explain why your wife's phone does better but it could help both of you get better battery life.
bik- The betterbatterystats file is attached. I see a lot of activity on her phone but very little for mine. The only thing that stands out to me is I have alarmmanager waking my phone for 10 mins and she had it waking hers for only 5 mins. I am not sure exactly what alarmmanager is though.
HTGaming- Thank you for the suggestion but I have already done that as well. I think I have literally turned off everything possible on this phone because it is driving me nuts to burn through battery like this. My OG droid used to us 30% in a day max and now I burn through that in an hour if I am using the phone for anything at all. Pretty much the only thing I had running on the phone lastnight was 4g service which her phone also had.
Another thing you can do to compare the two phones is to install battery monitor widget to see what the drain is on the phones. I used to have decent battery life but ever since the update, it's been worse. The one thing I noticed is that now my phone draws more current when sleeping than it used to. The drain is consistently close to 300ma, whereas before it would be less than 200ma when sleeping.
You have to have the widget on for the monitoring to be active unless you change the preferences.
I swapped the battery's lastnight and here's the results. Hers is still clearly better than mine even though betterbatterystats shows way more activity on her phone again.
Battery % left : 84% (mine) vs 90% (hers)
Data used overnight: 279kb (mine) vs 498kb (hers)
Time awake: 5min 32sec (mine) vs 12 min 8sec (hers)
Time in Deep Sleep: 7hr 58mins (mine) vs 7hr 59min (hers)
Someone posted that they saw different PRIs on phones even after the OTA. Do your two phones have the same PRIs?
damnn thats just weird
Im starting to think that some Rezound batches are differently tweaked than others. My first Rezound had great battery, I would stream music for 5-6 hours on 4G and would still be above 60%. My last two however were completely horrible, on 4-5 hours standby it losses closed to 20% with lil to no use. Same settings/apps as my first Rez. I regret returning my first Rezound, it truly was the perfect phone.
There really has to be a reason why some come with a 3.8 V bat. opposed to a 3.7 V. HTC wouldn't just send out two different types of battery for no reason.
You are missing 1 key info in your analysis, which people always seem to leave out when talking about battery life. The screen on time. I see in in the graphs but it's hard to tell the exact number. Because of the 720p screen on our phones, that makes a big difference. When my screen is on, the phone uses up at least 600 ma/hr. That is conservative, usually it is more like 700-800. We'll assume 600 for now. That's 10 ma/minute. Based on the stock battery, that is 0.6% per minute. So having a difference in screen on time of 10 minutes will give you 6% difference in battery life.
i am also unable to go for even most of a day on one battery charge - and i have 3 extra batteries that were from ebay that dont work even that long...
i do notice it when the screen is on the most - yest i used the gps for an hour and a hlaf without plugging the phone in and my battery lasted about 3 hours after that and died....
very bad....
very interested to see if its the phone or not - great work...
I'll try to answer a couple of questions in here. I got very frustrated yesterday so I flashed an ICS rom to see how my phone did with it. It is equally as bad. This morning, I got into work with 97% life, checked my email for about 2 mins and was already down to 90%. I have the screen display set to 30% brightness too. I am amazed that people can used 2-3 hours of display and still have 70% battery after 10 hours. My screen at 30% brightness probably drains 2% per minute. I think tonight I am going to try to install one of the stock RUU's just to check and see if the OTA upgrade possibly didn't install itself correctly.
HTGaming - I will check the PRI's tonight.
Bluesnake - Both phones were purchased the same day so I would guess they are from similar if not the same batch. Both have 3.7 batteries. Infact when I first got my phone, I could have display on auto, sync everything every half hour, use the screen for random browsing throughout the day and still go home with over 70% left. Somewhere along the line my phone has developed some sort of draining problem though and no amounts of clean installs seem to fix it.
b5fan - Both phones were off the entire night. I think screen usage was maybe 10 seconds for both of them. They literally just sat there on the nightstand while we slept and mine drained 2x faster with nothing running while hers ran facebook, email etc.
I checked the PRI on both phones and they are the same. I re-ran the stock RUU tonight so I will see if that makes any difference. I highly doubt it will but I am running out of ideas.
I guess I was thrown by the screen shots. They both show some noticeable screen time.
the only other thing I could think to check is the email type, push versus pull, and the frequency.

The screen time was probably just from me getting all of the data off in the morning like the screenshots and battery stats. Her email was on push and my email was set to not sync at all. Basically she had a fully functional phone and mine was set to do nothing which is why the battery drain is so hard to explain.
I did run the stock RUU image lastnight for my phone. I put it in airplane mode overnight and it was at 97% when I got up which is a huge improvement. I took it off airplane mode at 6am today and when I got to work at 7am, it was down to 90% so I guess I am in wait and see mode now. I have no email accounts/facebook accounts/ or anything else setup right now. It is only the stock image so there should be nothing draining battery today.
I can confirm the phone is no better now after the clean RUU install. Let it sit overnight and it was down to 80% this morning. I did not even setup any email accounts or download any apps yet. This is just the stock image from verizon.
