Well I was having horrible battery problems and came across a how to on the web and thought I would share this. Hopefully it hasn't been shared already and I apologize if it has. Its a way to wipe battery stats. MAKE SURE YOUR BATTERY IS AT 100% BEFORE DOING THIS
1. Boot into cwm recovery
2. Scroll to advanced
3. Scroll to clear battery stats
4. Reboot phone
5. wait for your battery to fully die before charging it again
And there you go its a pretty simple fix and is good if you have flashed a lot of roms. The guide said not to do it very often tho so I would be cautious but I did it once and now I am getting almost a day and a half with moderate use out of my stock battery! I have seen a lot of complaints about battery life.
Hope this helps let me know your results as I am new here

Wiping battery stats doesn't do anything beneficial - http://www.androidcentral.com/wiping-battery-stats-doesnt-improve-battery-life-says-google-engineer
After doing some research I did see that on androidcentral but can't wiping the stats when your on a new rom improve how your phone reports the battery stats as well?

If on a new ROM, you probably wiped /data, meaning... no more battery stats.
While I'm not sure if wiping the battery stats works or not, I just posted the following in the thread of the ROM I'm currently using since battery life is a big topic there. This is a guide that I came up with after a couple of weeks of analysis and tweaks:
I'm getting at least 48 hours on my battery now, no lie. I've made it a mission over the past couple of weeks to track down all my wakelocks and get rid of all the unnecessary processes that cause those wakelocks.
After 2+ weeks of analysis using a combo of betterbattery stats, badass battery monitor, and the stock battery info, here's a list of what I've done along with running TDJ's Evo3v7 Rom.
DISCLAIMER: These are my findings for my phone and my setup in my location and my typical usage which have worked for me:
-Make sure screen brightness is set to 'Automatic'
-Use Wifi as much as possible Vs data.
-From what I've read Facebook uses a ton of battery (wakelocks) when syncing in the background. I may be the only person on earth that doesn't have a fb account so I don't have to worry about it on my phone, but just keep that in mind.
-Under Accounts and Sync try to funnel as many accounts as you can THROUGH gmail. In your Gmail account sync only what you need when you need it. Do you really need the browser, contacts, web albums, etc synced. Can you live with manually syncing calendar once a day? Keep it to a minimum.
-Disable everything under Settings > Sound > System (the 4 items at the bottom of that list, keytones, touchsounds, screen lock sound, vibrate on screen tap)
-Make sure if you have a weather app that refreshes automatically to only have it refresh to what you need. Some of these refresh every 15min. Really? Just have it refresh manually or on unlock. I've found that to be fine.
-Make sure you're signed out of Latitude after you use it - if you use it. You can't freeze, uninstall etc, without freezing/uninstaling Maps, so make sure you are not signed into Latitude (or any other location service based apps).
-Location, location, location... Under Settings > Location Services uncheck all 3 options... may need a reboot to 'stick' after unchecking (these are sometimes checked by default when first booting up your device from flashing a ROM or you check them not knowing what all they do (I know I did at first). They are helpful when restoring but are a pain on the battery in daily use. This choice is yours as there are other recovery/restore methods but I've found that I don't need these checked at all. (Sometimes even going to Google.com enables the location service and it gets stuck in perpetual wake state, I've found).
-If you don't use Google Talk, simply remove it. Although I've found that 'GTALK_...' still has wake states even with it removed (phone still communicates with Google servers even when the app is removed), it's not near as much as it used to be.
-Freeze the Maps app - if it's feasible. Maps is one app that runs 100% of the time. Take a look in your 'running apps' and see for yourself. I rarely use my maps so I froze it. Since then, location services processes have dropped dramatically as have my wakelocks associated with location. This alone has helped out my battery tons. If I need to use maps, I simply unfreeze it.
-Finally, download and flash this by eugene373: http://forum.xda-developers.com/show...30&postcount=1 This has saved me more battery than most of the things listed above combined.
Hmm your link to Eugene's thread didn't work. But thanks for the info. And I guess that does make sense that wiping data would also wipe battery stats. That's why I'm a little confused about half the people say it works and the other half say it does so I figured I'd try it out

While I agree that turning off services or freezing them does help battery life, it kind of ruins the whole smart phone experience. The reason I have a smart phone is for up to date info at a quick glance. I am sure the info you provided will help some though. Thanks for posting.

Hi i did an update on the Google maps app a couple days ago and today I noticed that it has been draining quite a bit of battery. Does anybody know something that can fix this issue or do I just have to wait for an update?
Sent from my SGH-I747M using xda app-developers app
Turn off the GPS and exit maps....
Well it never happened before the update and it drains the battery when my phone is in sleep. Also the maps app is not opened.
Sent from my SGH-I747M using xda app-developers app
Just because it isn't currently on your screen doesn't mean it isn't open... It could still be holding a lock... About all you can do is turn off the GPS, and clear its data.... Either use TiBu to clear it's data, or press and hold the maps icon in your app drawer and drag it up to app info, hit clear data and clear cache... and only turn on the GPS if you're using it...
Ok but is there a way to downgrade the version to the previous one?

There's always a way... But it's not as simple as going to the play store and requesting an older version.... If you have the .apk you can replace the current one with an old one, or if you have an nandroid with an old one, you can unzip the nandroid, go to system/apps and get the maps.apk or just flash to an older backup and not update maps...
but that's not going to ultimately fix your issue... i really think it's just holding a lock all the time and it's the gps... which is why i suggessted turning off your gps, and clearing maps data... and if you keep gps on all the time that's pointless, unless you're navigating because apps can get your location pretty accurately based on the towers...

The thing is I've had gps and everything on before the update and it's been getting great battery life. It's only happened since this update. But I will try having the gps off and let you know how it goes.

Which is why I suggested turning off the GPS and clearing maps data... after that, turn it back on if you want, it's the only way to know if it fixes it... just have it off when you clear the data... any issue with a specific app, that's what you do first, clear all that data's memory of anything...
the latest maps update was soft rebooting my dads sensation...
but i know enough from using maps, that if it isnt on your screen (still in background) it DOES drop gps signal, and shouldnt be eating up battery in background.
Try "Autostarts" or something similar and disable maps at startup.

none of these solutions addresses the problem. the update has something that is keeping the phone awake and consuming battery. if I start my phone from OFF and let it sit for an hour, I can look at my battery stats and 10% of it will have been consumed by google maps, without me having ever opened it and without a single GPS query.
Then contact Google about the issue...
Probably Google latitude

Try turning off location services also. I was having issues with my phone properly sleeping and that turned out to be the cause.
The location services was part of my issue. Lowered the batt usage a lot but maps still shows up as a large user of batt.

I went to the apps info and uninstalled the update simple as that.
Edit: TiBu can also uninstall updates

The latest Google Maps is doing the same thing to my phone. I have always had GPS and location services enabled and it never ate up battery like the new Google Maps version. Turning off the GPS and location services is not an option for me so I will have to wait and see if they have a new update soon that addresses the issue. A big problem is if it cannot get a GPS lock due to poor signal from the satellite it will consume a high battery amount trying to find the signal. For now I am able to charge my phone a little bit in the car to make up for the extra battery use.
I'm really not having these issue and today is a day I'm actually using the maps and GPS... I'll keep looking at it and using and report my results... what ROM is everyone with issues running? Sammy or AOSP and which one?
Stock rooted. But I've reverted back to the older version of maps because of the battery drain

This didn't drain me at all today... I'll post a screenshot in a second... I used the maps for about 20 minutes, sat put for about 30, used for 20 more or so, and have left my phone alone since...
Hi guys, I have this problem since last night. Maps are running in background and there is nothing I can do about it, restarted the phone, pulled the battery for couple of minutes, cleared maps cache and data,force stopped and nothing. Never had problem like this before with any of my phones. The phone is 8 days old and everytging is stock. Thanks

Check if you have your location history enabled on your Google account. I do now, and it causes maps to request a location rather often. The battery life on this phone is good enough for me to leave it on though, I find it useful every now and then

Glad it's working for you! Yeah this whole time I never knew how much GPS use was actually draining the battery. I actually read an article online yesterday that talks about how GPS uses a crap load of battery. As of this morning, I only lost 1% overnight. I have 3 emails syncing, wifi on, rest of the syncs all on, google now off. No power saving apps installed. I know i'm saying this in all battery related thread but i'm super excited just like you and want to share the knowledge to all our Note 2 buddies ^_^
Battery drain <- Maps Always On <- Now <- 4.1.2
I noticed Maps was grabbing about 30% of my battery drain so I set out to figure out the problem. Conclusions are:
- 4.1.2 seems to have changed how location is used. I had Google Now on 4.1 and never had this heavy a battery drain.
- Maps was constantly running with TWO services
- Maps did not have to be open or visible, and reboot had both come back even after stopping services
- Disabling "Google Apps Location Access" solved the drain but this made it basically impossible to use Google Maps, because
- Maps would not use GPS without "Google Apps Location Access" turned on
I considered uninstalling Google Maps but realized that:
> All my favourite locations are on Google Maps
> Other mapping software also seemed to want all sorts of invasive rights, which I was not going to grant
So I:
* enabled GPS
* disabled Google Apps Location Access
* uninstalled Google Search (aka Now) using a 3rd party tool (rooted)
* looked for a new search software (let's face it this isn't really necessary is it?)
* found and installed Yahoo Search which I must say seems faster, more interesting and does not require unwanted access to my private data
Battery drain is back to normal, I have ful search and maps and GPS use.

Let's face it. Google is king of search. And that has spread to other Google uses, maps being a major player. I think Google needs to solve this by fine tuning how and when maps and/or GPS is used. Another big thing is Google needs to fine tune how our phones retrieve data in general. Apple has and is still working on it. Intel is fine tuning it majorly and you can see some of the results on anandtech where x86 and ARM SOC's are compared on windows RT. Randomly retrieving data for all data and apps is a nightmare. It would be nice if we could fine tune our syncs and data retrieval in set intervals or let the OS have a smart system where if x app needs this and it see 3 or 4 or whatever x apps need to retrieve data in the next 20 mins it will retrieve all in one fell swoop causing less wake locks and more idle/sleep time.

I had a similar battery drain problem... ~8% per hour when screen was OFF! Finally solved it by turning off Google Now AND the Location Service it used. I guess the problem is due to location history collection performed for Google Now.

Guys first thing first about battery draining is your mobile network not configure properly.. if its configure the network will not awaken your phone it just need a second to runing in background.. just realize it after I install configuration message from provider.. I drain 1% all over night.. and get 2day standby battery with medium usage.. 10 hours screen.. and leaving the phone with charging all night is weaken your battery.. first time I forget to unplug and everything change.. battery drain 5% after sleep 6hours..and only last for 1 day with medium usage.. 6hours on screen now I dont know how to make it back like it was.. using note for 3weeks anyone knows how to increase batt life without changing rom or kernel ?? Im still runing stock 4.1.1

Disable WIFI Scanning to improve your battery life. If you want more, disable Location History, and if that's not enough, go into Google Settings, Security, and disable all the features listed therein. Want more? Go into Services, and disable all the other tracking features, i.e. web & app tracking, search history, etc..., then remove your Google account.

Wifi and bluetooth.
Plus apps running in the background. I had bad battery drain for a bit last week from Google Play Services. Clearing all "recent" apps (some weren't very recent) and rebooting helped.

It does, as long as you are on a network. The drain happens when you aren't signed into one and it's searching for networks to connect to.

I don't know what the heck Google is doing waking your phone up so much with Play services, but it doesn't appear to affect functionality at all, and you will quickly see it drop off of GSam's top offender list.
Ive been on multiple ROMS and all of them have TERRIBLE battery drain issues with google play services. Currently im on ICE 3.1.1 but have used ARHD, Maximus, and LeDroid, all of them had this issue. i dont think its ROM replated but maybe some settings? im using greenify for ALL apps i installed including the google app, google play games, maps, street view, gmail, etc. if its not a system app, i greenify it. currently my phone has been on for 3.5 hrs and im at 85% with 30mins SOT and 37% screen off usage is due to google services. keep awake time is at 30mins. ive been on 4G most of the time with wifi turned off. what settings could this be related to? the battery dies so quickly when screen is off! just letting it sit idle for 10 mins dropped it 1-2%!
Using 4g usually uses more battery than WiFi so probably use WiFi when available. However that's still bad. Everyone has Google play services that has a US Android phone so everyone would have the issue if it were purely that.

As far as I know it's a more or less common issue that has already existed on my old One S. Maybe it's even older. (I'm not even sure whether it's a HTC specific issue.) If I remember correctly a real solution was never found. Sometimes a Play Services update fixes the problem, sometimes flashing a RUU and sometimes a clean flash of the rom you are using. (Luckily I never had to face this problem.)
These are what causing my wakelocks. The top 3. Anyone know what would cause those?
