I got the note 2 and im currently running the Omega rom with the Note2core kernel. The stand by time on my phone sucks alot!
I turned my phone into air plane mode at 6 AM in the morning and i turned it off Airplane mode at 2 PM and i had about 20 % left ! and my screen was not even on all that time ! Guys i really do not want another huge bulky ass extended battery on my note II i just want the phone to get me through the damn day! my brightness is set to 50%. The battery when my screen is on is good but not great aswell it lasts around 1-2 minutes on a single %.. What would you recommend guys..i really need help on this one' TY.

Install Juice Defender, it helps managing wifi and 3G/4G on/off when you don't need them, actually the most thing kills your batteries are wifi and 3g.
I usually get 2% drops from sleeping for 8hrs.
btw im using WanamliteV2 and redpill 0.9 BEST COMBO!!!!!
Hi, ill tell you a little bit about myself and then get into suggesting how you can get better battery life. Okay, i have a Note 2 flashed with WanamLite V2.0 & RedPill Kernel. The battery when i got my Note 2 on the stock rom was great. But i ventured into a custom rom for the further enhancements to my experience. So i flashed on WanamLite ROM V1.5 and the regular RedPill Kernel (Rev.0.5), With only Power saving mode on and brightness set to Auto. I would get approx 20 hours total time & 8-9 hours scree on time. Then of late i decided to try out Omega ROM V7.1 + uNEAK Kernel. = Results were the battery life and performance sucked! So within 2 hours i flashed back on the newest version of WanamLite ROM (V2.0) and this time flashed RedPill Ultimate (Rev 0.7). (This version of RedPill kernel had the ability to undervolt the phone so i decided to try it out.). I undervolted each clock speed -50mV. And than my standby time went to 27 hours with 10-12 hours screen on time. (With the same settings as above). This week i decided to give Omega ROM one more chance. So a few days ago i flashed on Omega ROM V7.2 + RedPill Kernel Ultimate Rev 0.7. This time my experience has been amazing. I get better battery life than WanamLites ROM. (And i also undervolted the phone the same way as i did previously.) So as of now my total standby time is approx 30 hours with 10-13 hours screen on time.) I also have my WiFi sleep policy set to "Never" And under location services i have all 3 options uncheckmarked, motion turned off.
Getting good battery does not only depend on the OS / Kernel, it depends on you as well. And your habits. What features you have turned on. (E.G, Wifi, Data, GPS, Bluetooth etc.). Here is what i would recommend you try out:
1. Flash WanamLite ROM (V2.0 or newer).
a) While in Aroma Installer choose NOT to install any of the Bloatware. (AllShare, Talk, Yahoo News etc.)
2. Flash RedPill Ultimate Kernel (Rev 0.7 or newer).
3. Install SetCPU. Set governor to Pegasusq, and IO Scheduler to Deadline. (I get the best battery life with this combination).
4. Undervolt the CPU Clock-speed's by -50mV.
5. Turn Power Saving Mode ON - In settings.
6. Turn OFF Motion based features.
7. Set WiFi sleep policy to Never.
8. In settings under Location Services. Uncheckmark all 3 options.
9. Turn LTE OFF (If your phone has LTE).
10. And if your using a WiFi network, turn Mobile Data OFF. And vice-versa.
11. If using Bluetooth, turn it OFF when your immediately done. Same goes for GPS.
12. Leave brightness set to Auto OR under 30%-40%.
13. Invest in Titanium Backup, and use it to freeze or uninstall bloatware or junk software you DONT need! Also use it to regularly backup your apps, in case you need to flash another rom in one touch you can restore all your apps!
Try my above suggestions, and if you are still getting horrible or bad battery life than there most likely is a defect in your battery! With doing the above, you should at MINIMUM get 1 day out of your battery! (With doing the above, i can get upto 3 days!!! With medium usage! And atleast 2 days with heavy usage!)
My $0.02 cents, hope my suggestions will help you!

Im currently on Omega though should i go back to Wanam or stick with Omega for now? Blue tooth , GPS is off most of the time and im mostly on mobile data so my wifi is off. Should i really go with the powersave settings to get 1 full day from my battery though whenever i check it my phone lags in the app drawer and in scrolling home screens i really wish you'd reply me back so to go with Omega or Wanam and on a side note man , in my battery tab in settings its always Media using 62 % of my battery..Dont know and only 19 % is my screen but yeah man reply me back please thanks man!

Hi, I would say go with WanamLite as no 2 Android phones are the same, and you are currently on Omega ROM and experiencing bad battery life and performance. I have power saving on all the time. I have never had any issues with lag! With power saving mode on i get a benchmark of 5800, with it turned off i get a benchmark of 6700. So just from that you can gather i have no performance related issues with power saving mode on. Also dont forget to flash RedPill ULTIMATE! A good kernel makes a HUGEEEEEE difference in performance and battery life! I have tried a few different kernels, so i can safely say that RedPill Ultimate is the only kernel that gave me the best battery life ALONG with amazing performance WITHOUT ANY COMPROMISES!! And media using up 62% of your battery that is something that is not right! Try removing the Music Player Widget from your homescreen and see if this persists. But once you flash another rom this issue should automatically be resolved.

tbh i think Omega has gave me a little better battery life then Wanam because when i was on wanam today morning it dropped from 100 to 20 even when the phone was on airplane mode and the screen was off all the time!

Try the suggestions i gave you in my first post, including the flashing of WanamLite & RedPill. Follow all my instructions and use it for a day. Tell me tomorrow how things fare out,
I dont everything you told me to do except the power save i unchecked screen power saving that made my phone lag and ive been drawing on the s note and its been in 57 for a couple of minutes..i think why my phone keeps draining battery when my screen is off is because of deep sleep..it drained 80 % when i was on stock kernel i hope that doesnt happen with red pill i flashed the ultimate 0.7.
Thanks alot man again ill give you my results tomorrow!

i dont understand, so you DID everything i told you to do including flashing WanamLite? Also in deep sleep the phone uses less power ... also i forgot to mention. Go into Settings - SPen, and turn on the battery saving feature. It REALLY helps. What it does is, when the S-Pen is docked inside the phone, it turns OFF the Wacom digitizer thats embedded into the phones regular digitizer saving you battery! I noticed a significant boost in battery life when i first turned that feature on.
Yup did everything including flashing Red pill and Wanam rom (i already had it in my pc ! ) but im using CPU spy and my phone isnt going to deep sleep im pretty sure my battery drain when in standby is from it not going to Deep sleep

Not really. Im a heavy user and my screen is almost always on. And my battery life is amazing. Did you also undervolt the phone using SetCPU and change the governors to what i suggested?

Yeah i undervolted each one of them to -50 using setCPU it definitley bumped up my battery life but ..i really need the phone to go to deep sleep cause i just left the phone for about 3 minutes and dropped 3 %..should i update to the Stable version of 0.9 or stay with 0.7 ultimate?

There are 2 versions of RedPill, Stable, Ultimate. I was using stable for the longest time. And recently started using Ultimate. Ultimate gives you the features to undervolt. And i would recommend you stop flashing rom after rom and same with kernel, You have to give the ROM and Kernel some time to set in. Now that you have followed my instructions i would suggest you just use the device normally without worrying about battery life for atleast a couple of days. Hopefully by then everything should improve and settle in. The whole issue of deep sleep, as far as I know the phone has to be sitting idle for quite some time before it goes into a deep sleep. I could be wrong. The moment you turn off the screen the phone does not / is not supposed to go into deep sleep! Also one more thing you can do, which i also forgot to mention: Go into SetCPU, slide to the right to get into the "Profiles" page. And make a new profile, so that when you turn off your screen, the Minmum CPU speed is 200 Mhz, and the Maximum CPU speed is 400 Mhz. That will also boost the battery because it will limit the processor to down-throttle while the screen if off! Remember, dont jump the gun and flash anything else. Let everything settle down and than let me know tomorrow if you see any improvements!
---------- Post added at 03:41 PM ---------- Previous post was at 03:39 PM ----------
Oh and one more thing, since I believe this is the third ROM you have flashed today or at least the second. Boot Into ClockworkMod Recovery and goto advanced, and wipe your battery status!
Batterylife issues?
Well... I'm running Jellybam (CM10/PA/AOKP) and I can use mobile data, Wlan, GPS, gaming, listening music and phone about 11 hours while surfing in the web and stuff and I'm going down to kinda 10% in that time. Oh, I got the N.E.A.K. kernel flashed.

I havnt tried that ROM, but i have certainly tried that Kernel, and i didnt have any good luck with it. Based on your usage i think maybe you would benefit from trying out WanamLite ROM + RedPill kernel. You will most certainly get close to 18-24 hours standby time and more than double your screen on time. Try it out!
Install BetteryBatteyStats and then check Kernel Wakelocks and Partial Wakelocks.
Should help you narrow down what is causing your phone not to go into deep sleep. Probably some rogue app.
As citizenlee said, install better battery stats. From what you've said it definitely sounds like a wakelock issue because I have wifi, data and gps always on with stock rom and kernel and my phone gets me through the day easily. Normally about 17 hours total time with screen on about 5-6 hours.
I also have autosync on with everything as push.
Can you post a screenshot of your battery usage including the main usave page and the detailed one that you get when you click on the graph

Perhaps with airplane mode on (wifi, bluetooth, nfc, data, gps etc all disabled) and screen brightness all the way down, it could be possible to get that 13hrs if you are just reading a book?
But with realistic everyday use does seem farfetched lol

I just flashed MIUI last night and noticed that my battery is being sucked dry pretty fast. I suspected that it is due to sync being switched on. Where can I make adjustments to the frequencies of the sync?
Either from the app or Settings>Personal>Accounts & Sync
Although I didn't have ANYTHING setup last night when trying it and lost 6% in about 10 mins - something's not right
Try resetting your battery indicator http://www.miui-au.com/howtos/reset-battery-indicator/. It is also recomended somewhere on the miui-au.com site to not charge your phone while flashing because it is somehow disruptive for the indicator.
I know all that, I wipe:
data/cache
dalvik-cache
battery stats
rotation settings
before flashing ANY ROM. Battery life is still crap

The weird thing is I wasn't charging the battery while flashing. I find it a bit surprising for MIUI 1.2.4 to be quite a beast in battery usage.

What would you consider a good battery life?? I flashed to 1.2.4 and it seems to last me all day without any problems?BUt I have noticed slight 5%-8% drop in the 1st hour or so but then it stablises throughtout the day. Ive not tweaked my phone with setCPU and I dont intend to either.
Something is rly wrong with your MIUI. Anyway, never use that Kernel which comes with miui. Use Vork or Coutts Kernel.
pls download current widget from market and test how much mA it drains in "screen off". im using miui-au 1.2.4 r2 with vork kernel and im losing 1% per our with wifi, sync and gps on. it uses 4-5 mA with screen off.
With previous MIUI builds, and with my own ROM I'm using now, I can go from 7:30am til midnight and still be on circa 50% battery. This is with my normal weekday usage. It goes down to about 30% by end of the day on weekends as I use the phone more
This build drops 5% in a few minutes and I just don't see that as being any good

I don't need to download anything, the ROM was dropping battery with NOTHING setup except for Wi-Fi. I didn't even setup my Gmail account to get my contacts!!
I think I can skip the obvious as I know full well what I'm doing and never had this issue with previous MIUI builds, and I never use the stock kernel - I always go for a Coutts one before first boot
I was wondering is someone can help me. I've been using Deck's ROM's for the HTC EVO 4G for some time now and I hear about all these guys getting 20-30 hrs of battery life. I'm currently on 1.2.1 and have never got probably more then 11 hours out of my battery life with heavy or mederate usage. I've updated all my radios, wimax, etc....I've tried different kernels, I've installed vipermod and undervolted, I have CPU profiles. I've installed a new 3F3D driver. I've tried the wake lock fixes and still nothing has changed. Am I missing something here to how these other guys can get that performance out of their batterys. I'd like to post this directly to his thread but this is my first post and I guess I need at least 10 posts. I'm a bit of a noob but can hold my own.
I run decks with tiamat kernel 4.0.5 and I get outstanding battery life. Give this a try then let me know how it works out. Check your accounts to see if anything is synching that's insignificant. Then check your apps update frequencies. Lastly, turn off all of the haptic feedbacks, animations, and effects. Live wallpapers kill a lot of battery too. You might also want to try enabling and disabling auto brightness to see which is more energy efficient. If your overall goal is great battery life, then a lot of the bells & whistles are pointless.
It is nice to be important, but it is more important to be nice.

I've tried tiamat 3.3.7, 4.0.5, and 4.0.6 and have got the same results with all three. I've tested each and one of these over about a week period. Currently I am trying SavagedZen 2.2.1 and up til this morning it hasn't changed much. I've took off all auto syncs. All haptic feedbacks, animations, and effects have been turned off. Never use live wallpapers and have read that lighter wallpapers will conserve battery. Right now I have auto brightness off and down to about 35-40%. I did however just checked off data enabled about 2 hrs ago and seem to have got better battery since. So far I'm at 82% with about 4 hours of moderate use. (mostly texting and surfing the web). I didn't know if there was any other tweaks internally that I'm missing or if it's more of a puzzle with what combinations to use.
Just saw my background data was enabled. I unchecked that as well. We will see how this goes I guess.
It seems like it's definitely data related. I downloaded skype from one of the forums strait to the phone and my battery percentage went from 79% to 68% just for the duration of the download. Is this common?
Do you use an SBC kernel? Have you whipped battery stats in recovery? Have you tried using the kernel governors (smartass, powersave, conservative) without setcpu?

I have used kernels with SBC and without and haven't seen much difference besides the initial 10% loss of battery. I usually I wipe cache, Dalvik cache, and battery stats everytime I flash a new ROM in recovery. I usually do a factory restore too. I've used smartass and savaged zen as governers as well. Currently I'm using savagedzen governer with a max at 1036 and a min at 245. I also calibrate the battery when i flash a new ROM. Currently I'm standing at 60% battery with about 7hrs and 37 min on battery. Probably the best battery life I've seen. I'm still seeing massive drains when I use 3G. I was just on xda forums on my phone for about 5 min. and the battery went from 65% to 60%. If I turn 3G off it stands idle for awhile.
I'm scratching my head trying to think of what will help. You probably won't like this, but when my rom has me stumped with a problem, I wipe and start over. Maybe an extended battery is the answer? They are dirt cheap for the EVO now.
It is nice to be important, but it is more important to be nice.
Yea I was thinking about an extended battery as well. It seems like taking 3G off does wonders for the battery. Are you keeping yours on or off to get great battery life?

Lowering your max and min cpu frequencies will improve your battery life. I've always used 128 MHz as a min with no ill effects. Ever since I got my evo I've kept the max at 998 MHz and it was plenty fast, but I am currently trying out 691 MHz max and it seems just as snappy so far (battery life was great at 998 MHz max for low or moderate usage, but with heavy usage I've noticed it drains too fast). I'll probably try out some lower max frequencies to see how low I can go without affecting performance.

Use JuiceDefender to automatically toggle your data connection (3g/1x) off when the screen is off. This will dramatically improve your battery life especially when you're in areas with poor signal. If you want, you can set it to turn on the data connection at user-defined intervals so emails, google voice, and anything else that needs a data connection to be refreshed periodically can go through. With the paid version, you can even allow exceptions for programs like google music, pandora, or wireless tether, so they can keep the connection while the screen is off if they're in use.
Ill try juicedefender. I had it before but didn't really know what settings to use. Current battery is doing well. I'm curious to if all these people experiencing 20-30 hrs of battery life have data turned off a alot. I'm currently at about 14 hrs. with about 42 percent left. Thanks for all ur advice.

I can easily get over 40 hours with light usage and over 20 hours with moderate usage, but that's only because of JuiceDefender. Without it, my battery drains like crazy at work where there's really bad reception.
I use the customize profile with mobile data enabled, schedule enabled at a frequency of 30 min, and apps enabled when the screen is off for google music, pandora, and wireless tether. I also enable the text notification which puts the icon in the status bar. I've run into problems when I disabled notification where JD gets shut down in low memory situations, but having the icon in the status bar prevents that. I leave wifi, location, and night mode diabled, but that's just because they're not useful for my usage. I'm sure the other profiles work fine as well, but I just like knowing and controlling exactly what JD is going to do.
Try using saveged Zen with conservative governer, viper mod and other little things people have mentioned

I'm going to run JD all day today with those settings to see what it does for battery life with my data on. Yesterday seemed to be the best battery life I've recieved with data off for the majority of the day. Got about 17 hrs with 39% left. I'm happy with that. If JD can get me something like that without having to toggle with data on/off that will be nice.

I've run viper mod with tiamat before and undervolted 50mv with little or no change in the overall performance of the battery. Any suggested settings for savaged zen using viper mod?
Undervolt as much as you can, all phones are different. As for jd, sorry I forgot about that. It's a HUGE improvement. Your battery can pretty much double. It can be a little annoying in some cases.

Didn't really get to do a full trial on battery life yesterday. I downloaded a Sense Rom and tried some troubleshooting that I read on Deck's page but it didn't work. Today will be the first full day I try JD with 3G on. I will probably try viiper mod tomorrow after the results I get for today. Thank for the help guys.

You can't judge in one day.. you have to wait like 3 days of use to let it settle down
Deck's + SZ + SuperCharger script + ViperMod script.
I believe I have found what i belive is just about the perfect setup for this ROM
My evo is lightning fast, in app performance is almost comparable to my xoom
And with heavy usage my battery lasts at least twenty hours
Kernel: savaged Zen 2.2.1 bfs
Setcpu info: Max clock to 1136, try 1152 if 1136 is stable for Max clock, min 245. Savaged Zen governor, screen off profile with interactivex governor and min bumped to 384mhz. Eliminates all screen on lag
Market app: chainfire 3d its a graphics driver that increases all animations, 3d effects efficiency and speed, and improves battery life IMO follow in app instructions and install the driver, make sure to nand backup first and to not have the phone connected to the charger or computer when installing
Market app: battery calibration wipes battery stats to build new ones that are correct for your ROM kernel setup
Advanced setting in settings menu: performance settings, VM heap size set to 48
Market app : SD booster set SD cache to 3000 makes all SD apps and media faster.
Market app : busy box install 1.18.4
After all this install any user apps you wish and run fix permissions in ROM manager or recovery
Its a lengthy setup, but there is much profit to be had. This setup is faster then I've ever seen an evo run and has the best battery life of any ROM kernel combo I've tested.

Hi all!
How do I find what exactly is draining the battery?
Ie. is there an app or something that can tell me what exactly is doing the damage?
(Settings - About - Battery use is not very helpful: now i know that it's Android System and Cell standby.)
It used to work perfectly fine for up to two days with wifi, 3g and sync. Up until cca a week ago. Now, if 3g is ON, the phone gets really warm and eats battery life in just a few hours. Wifi, on the other hand, can be on (sleep policy: never off) and i still get 1-2 days of battery life.
Specs:
Wildfire
CM7 nightly 256 *
latest radio *
* doubt any of these two is the culprit - trying to resolve the battery issue i updated my CM7 nightly (v.80 or so) to the latest one (v.256). Full wipe as always. That didn't do the trick. That's when i found some posts on xda suggesting that flashing the radio might help. Tried that too. No joy.
Try with these 2 apps. It should provide an overview:
CPU Spy (To see if your phone downclocks automatically or not. An 8 hour battery life on idle doesn't suggest it to me)
http://forum.xda-developers.com/showthread.php?t=1011497
Better Battery Stats (Important - You can check the Wakelocks and actually see the process name which is consuming CPU cycles / battery. Its all explained nicely in the OP)
http://forum.xda-developers.com/showthread.php?t=1179809
I am using CM7 Nightly 256. I'm getting a good battery life (1 day approx) I recommend you to remove unwanted apps, disable autosync, disable gps when not in use. And ya use the apps recommended by 3xeno as above
And consider using SetCPU. Screen-off profile.
Thanks for the suggestions. Looking into it at the moment with better battery stats (and it's documentation). Will post a solution if i find one.
i have the same problem with battery...must charge daily.
same problem here
Running CM7 7.0.3,and after starting to use the ICS theme,started to get battery drain.
BBS shows the progress "suspend" work extensively,but can't figure out which program is causing this.
CPU Spy show 84%-85% in deep sleep,which means something is running back there.
See attached Jpegs.
Will a newer kernel flash do the trick?or will a Rom upgrade?
Thanks in advance.
Try to use CPU Master Pro. In Screen Off Profilles try to put 264Mhz Max CPU frequency
Before that my battery live 3 days

84-85% on deep sleep is fine. As per your screenshot, are you getting 18Hrs battery life (From 100 to 40)? If that's the case, it's actually pretty good battery life.
i wanted to ask. do heavy themes consume too much battery?
In my eyes any colours on the screen would use more battery than a black image. It's probably not that noticeable though.

Blacks are more energy efficient on LED screens only, since there the LED can just turn off.
Here the LCD needs to display a black color.
Hey, I'm trying to fix my battery drain during light use. Having screen on for not even 5 minutes eats around 2% of my battery. I've calibrated, gone through many different ROMs [GB(CM7,MIUI,Sense) and ICS] with full wipes(format and wipe). leading to my question in hand... how do I completely wipe my phone? I visit the wifi settings and see a wifi history that were from a pretty long time ago(before wipes). This leaves me thinking I have not fully wiped my phone in between flashing. Does the google account save wifi history or something? Thanks for any tips!
My problem still persists any help is appreciated

You seem to be wiping your phone correctly. The WiFi settings are backed up under the Google account and are restored when you add the account again. It also backs up other settings, wallpaper, and app data of certain apps. Here's an easy way to fully wipe your phone (including the SD card app files in .android_secure) - http://tinyurl.com/66fc8og
It's called super wipe script and it is from the Android Revolution HD ROM thread, thanks to mike1986.
Sometimes the battery loses it's ability to hold charge after sometime. This happens when the battery is quite old or due to various reasons that I don't know. You'll need to get a new battery then.
On the ROM side, a good ROM+kernel combo gives the best battery life. Instead of using a plethora of apps to save battery, finding the right ROM & kernel combo and choosing a good CPU governor and min-max frequency settings will give you much less battery drain. I don't use any battery saving apps, but I run a great ROM (CM7.2 RC1) with an awesome kernel (LorDModUE 8.9b7), with smartassv2 governor running 122-1152 Mhz and a few build.prop tweaks.
You can try out my combo and see if you're getting any better battery life. The max I've gotten recently is 14 hours of heavy use with 4 hours of screen on time, wifi on for 75% of the time and a lot of web browsing and video watching. I usually keep my phone in 2G mode and only change to 3G when I need to use the internet. 3G drains the battery really fast. On average I get around 13 hours heavy use, 1 day medium use and more than a day of light use (with mobile data off unless when necessary). I get around 1% per hour drain in standby.
You can try this ROM VictoryMod by victoryo. It has my same ROM+kernel combo I've mentioned before + build.prop tweaks. Change the CPU governor to smartassv2 with 122-1152 Mhz frequency. It gives great battery life.
Among the Sense ROMs, Android Revolution HD with klquicksall's kernel and LeeDrOiD HD with LeeDrOiD's kernel give awesome battery life.
Thanks for the reply! I greatly appreciate it. As for my ROM, I've been using the latest LeeDroid, but the battery drain seems to be happening across all the ROMs I've tried recently. I never install battery saving apps, and I keep default kernels and settings. The problem is probably with my battery, I've had this phone since last May, so almost a year. I'll see if I can get this problem sorted out. Thanks again!
A few days ago I started running a nightly of Franco Kernel. My battery life immediately increased and I was able to run for about 18 hours and 2.5 hours of screen time. However, after each progressive day, the battery life has decreased steadily until today I was barely able to squeeze out 12. I've checked my battery stats and it doesn't show that any particular app is hogging all the battery or anything. CPUSpy also says that it's entering deep sleep as usual. Any ideas and has anyone encountered this issue? Franco 156 with Liquidcool 1.4
Thanks in advance.

That could be dependant on soooo many variables... How is your signal strength in the area you reside? What are your settings, governors, Any kernel wakelocks? What are your ROM settings. Are you in WIFI, 2G or more?
I don't think you'll get an easy answer on your question here. Just play with your settings and see what suits you best.
I myself am using Franco with the Rascream ROM and getting currently 4hrs of screen on time on stock 1750 battery.
My settings:
ROM: Rascream
Kernel: Franco r174
Powermode: Balanced
Governor: On demand
Min: 729 MHz
Max 1228 MHz
OMAP4 interface 1.4
No other performance or battery saving apps or tweaks....
Just test your settings and be aware of wakelocks (but you allready are since you have the batterystat log included).

Could you explain why do you use those?
Why not power save mode or lazy governor?

That is simple. I get about 17hrs uncharge off which 3,5 to 4 screen on. That is sufficient for my use. With Lazy and power safe I feel that the performance suffers too much. With these settings everything is still smooth and snappy... as you can see I adjusted the min and max from my CPU above the standard that comes with balanced power mode for the same purpose.
Thanks guys. I moved some things around and I'm getting better life again. It seems like the problem lied in either an app called 1Weather or My Data Manager. Have any of you heard anything about those apps?

I've used 1weather for months and it has never negatively effected my battery.
I'll play around with it for a few days. I wouldn't have imagined that it would be 1weather, but due to the nature of My Data Manger constantly keeping track of something could have run the battery down. Funny how it never showed up anywhere. Though the battery drained significantly during standby. I uninstalled both and battery is fine now. I'll see what happens when i put them back.
