Hi,
I just recently bought my Inspire and rooted/s-off/eng s-off.
I flashed Android Revolution and I can't stand that I can't have my phone for more than 6 hours before 15% battery.
Is there any other ROMs that have better battery life? I'd rather have something like an optimized stock, but I really would love better battery life.
If you're wondering, I don't do a lot on my phone--just music, texting, and mild web. No video, and some e-mail.
Thanks~
For me, CM7 has better battery life than AR.
It's AOSP though so no sense. Though honestly I don't miss sense at all. In my experience the only feature that sense has over stock is the dialer and camera.
How long were you using Revolution? ROM's need some time to even out in the OS. At first they'll rip through the battery like nobodys business. Also, did you reset the battery stats? I'm pretty sure that is in the Revolutions FAQs. I could be wrong though. Also, the ROM in my sig is a great one to try. He also had a sense version if that's your bag.
Phone Battery usage statistics
I flashed CoreDroid V5.1 two days ago, and i'm sad to say i'm experiencing similar DISMAL battery performance. I've ran specific tests on it all day today, and this is what i have seen thus far:
08:12 - 95% - Airplane mode ON
09:46 - 91%
11:32 - 86%
12:30 - 83% - Airplane mode OFF
13:27 - 73%
14:33 - 62% - Airplane mode ON
16:30 - 44%
These stats were taken with the phone NOT IN USE. The screen was off and it was sitting on my desk. So, as you can see from the list above:
with AIRPLANE MODE ON - a loss of ~3-4% per hour
with AIRPLANE MODE OFF - a loss of ~10% per hour!
This is patently ridiculous!
When airplane mode is on and the phone is not in use, it should be basically on standby, using maybe a percent every hour or two.
When airplane mode is off, 10% /per hour?! That is just INSANE! No WONDER i can't get until even 7pm before my phone is dead!
If it can be determined what is sucking down the battery with Airplane Mode ON, and that 3-4% is eliminated, then the phone should have no problem lasting >14 hours.
(As a note, i saw similar performance before i rooted, so it's not just the ROM)
Moved as not android development.
I don't know if it's just how Sense works, but whenever I view the Applications in Settings, ALL my apps are running, ALL the time.
I don't remember it being the case with my Captivate, though..
Charge your battery till it completely charged. Turn the phone off and boot into ClockMod Recovery. Wipe the battery stats and hopefully that should help with the battery.

If i leave my phone alone over night while i sleep after 8 hours it will be at 93/94%.
Download an app called CurrentWidget. It will tell you how much your battery is being used.
Remember to enable logging so you can check the log latter on your sd card .
With my phone idle I normally get ~3mA or less per minute with spikes of ~160mA once an hour or so.
The max "Screen On" time is about 2 hours per charge.
There is also an app called Traffic Monitor Widget to see how much data each app is using.
These may help you understand what your battery drains so fast.
I'm not Rooted.
I'm seeing some pretty decent battery life on CM7 RC4. Here are some screen caps.

I dunno really. I just took two more screen caps from today. Just my general days usage. I've had the phone for only a week now so I expect the battery to break in a bit more like my nexus did. I was a bit worried about the battery life and this thing lasting me throughout the day but I have been impressed so far. I never even used it with the stock ROM so I can't compare, I dislike Sense.
I've been off the charger for 13hours. I'm at 50% with 1h10min screen on time too. I've had mine for about two weeks now.

I'm running coredroid 5.1 and I fail to see that I'm loosing 10% an hour. Here's how my day was in battery faintly remembering. Woke up at 9:30 took of charger and left for work by 10. From then to I say around 1 I had around 90% only cause I was messing with my build.prop so I was restarting my phone like 20 times doing some test. Also I was ebbing a lot to look for info on what I was doing. And near the end of work around 5 I had even been playing music and games. And was around the 60% I wanna say in the high 60% I played with my phone a lot today and as of right now the same day I'm talking about I'm at 44% and been on my phone like crazy even rebooted a few times again. From what I have been doing to my phone I highly don't see how u could loose so much battery. So from now 10 to to 8 I'm at 44% that 10 hours I was playing with my phone like crazy.
Tips. Use recommended radio's. Charge to 100% clear battery bin. Also give it a few days for the Rom to get built in a little bit. also go download frail CPU its free. It'll help you save some juice when screen is off. Hope this helped.

thats because your phone is sitting in standyby 90% of the time. I've never checked my battery use and NOT had display at the very top using at least 50%. Its not wonder your battery life is great
I have been on many Roms but cm7 rc4 is the best for me. I get about 18 hrs of life with normal usage and gaming. I think Sense is the culprit on other ROMS. Also the free memory on cm7 is 200mb more than on Sense. And this is 90% of the time for me.

I have noticed something funny about the battery stats on different ROMs. In particular, on CM7, I would never get display as using more than about 10%. On the other hand, when I am running stock rooted ROM, my display always uses about 60%. This is all with similar usage patterns and similar brightness settings. What is going on there I wonder?
I have also never seen my display less than 40%! Even today.
Attached are screen caps of my usage, based on what was happening earlier.
So lets see, display was on 1 hour out of 15 hours. And that = 40%. yea. i call bull****.
Thank you to all for your suggestions thus far. I will try them all out and report back what i have found!
I am heaving very good battery life with CorDroid 5.1 But I also had good battery life with Rev roms. When I am in a fringe service area I switch to GSM only and it more than doubles my battery life with the radio I am using. If I dont need the high speed I leave it off if it is not a strong signal.

unplugged 2 hours, wifi on, gps on, auto update on, facebook, played friut ninja for about 20 minutes, 1 game of cribbage, and been getting 4-5 email per hour, battery at 86%, before I would have been at 60% with that much use.
Anyone else seen battery life increases?
This. It's noon and I'm still at 80%. I used to have to set my phone to flight mode all day at work just to make it through the day. Now I can leave 3G on all day and not worry about it. That's the best part of the update in my opinion.
I was about to post this also. Yes, I have noticed a dramatic increase in battery life since I've updated. Now granted, it's been less than 24 hours but it is noticeable. I'll see how it goes over the next few days. But I agree, I am very happy with the update so far.
Which ROM we're you guys running before? FJ6 (stock)? A lot of users noticed better battery life after updating to some of the leaked builds (JH2 onwards)

4h 45min since unplug.

Glad someone else noticed this
I'm a victim of the partial update but my battery drain has been nearly half! I've actually left live wallpapers on and can make it through the while day at the rate I'm going

6 hours 53 minutes since unplug and I'm at 23% battery. This is roughly on track with previous battery depletion, but today I've been doing heavier internet and Facebook use than usual. I think that, previous to this update, I would have had to charge by now. This is with background data and sync on, over wifi, with a combination of Google Listen, Music Player, and Pandora use.
The telling point is that screen battery use is about 10-12% lower than usual for this type of usage, at 54%. I've seen it as high as 70% on days when I'm playing around with the phone a lot.
I'm ready to call this an improvement.
Sent from my SAMSUNG-SGH-I897 using XDA App
My phone was at about 75% at around 8:00PM last night. It's currently 2:42PM now and it's only down to 25%. Granted, it was in sleep mode from around 12:30AM to about 7:00AM. But I did use it moderately last night and throughout the day today. So the battery performance has definitely improved for mine (stock with yesterday's update).
For those who have seen an improvement:
- Did you use a task killer pre-update?
- Are you using one now?

Unfortunately my battery life has been greatly decreased by the update. My phone is rooted, but the update installed without any trouble on the first try. Before the update the phone was fine between 9am and 1-2am without charging it at all. That's being on wifi most of the time, and maybe a bit of talking, e-mail, and rss reading. Once asleep I'd let it charge overnight. Typically Display used the most battery, usually about 50%.
Since the update I find that I need to charge the phone in the middle of the day. The first full day of the update I used the audio player for several hours, so I thought maybe that was it, but I've done that before without a major impact on the battery. Today I didn't use the audio player at all, and after 8 hours the battery is down to 26%.
According to the power usage information the largest consumer is Voice calls, at 29%. That was 11m 46s of call time. Looking at Juiceplotter, for a typical day at work before the update my battery dropped about 2% in 2 hours, with the phone on wifi, and otherwise idle. Today the phone lost 6-9% in 2 hours of being idle.
The last time I charged my phone was yesterday morning. I just plugged it in an hour ago at 15%. Thats like, 35 hours on a charge after moderate usage. Not bad. Much better than my old G1 heh.
I'm at 45 hours, still at 29%. Light usage, probably ~12 hrs in flight mode, but music player on for about 5 hrs, 5 min voice call, a few texts, some facebook/web. Still very impressive!
I've had slightly better battery life since the update.

I am running cog 2.2b5
Just wanted to compare battery life and post the rom you are running too
Sent from my SAMSUNG-SGH-I897 using XDA App
my battery life sucks. i get about 10% per hour....
What Rom are you using?
yeah my batt isn't too great either. 2 days on Cog V5 now. Each day has been roughly 10hrs with about 4.2hrs use. Each day I ended with maybe 1-2% left.
Is this normal? Froyo didn't help a bit. In fact it may have made it slightly worse.
When I flashed b5 ... it was great. Then I found my gps sucks on it so I flashed again and I found that the battery drains like water 1% every 5 mins! ( Idk what's going there) Then, I flashed again and the above post is my result and my gps still sucks. So maybe if you flash it again it might help. I re partitioned in odin as well.
I am using Froyo (JI6) with lagfix and I get a consistatnt 12+ hours of moderate use. I usually charge my phone every three days.
Cog 2.1.7
I have to charge my phone every night. I have used multiple roms from cog 2.1 and even cog 2.2 as well as stock and it all seems the same.
There is no way that is an accurate picture... there is no way you made phone calls or used the facebook app without it showing up in usage.... u may have gotten 40% out of 12hrs but you did nothing with your phone

I use tons of apps on my phone and the only things the show up in my battery usage are: Display, cell standby, phone idle and voice calls.
you need to recalibrate your batteries or flash from 100% as DesignGears had mentioned earlier.
i now flash from 100% batt life when upgrading to new ROMs. or do a search for battery calibration.
Not sure how to do a screen shot but Im running 2.2 beta 5 and I thought battery life sucked but it was because I was checking it constantly and playing with GPS.
Today, after recalibrating battery stats two nights ago I have dropped 3% in 3 hrs of standby and very, very light use.
Also, to recalibrate battery stats I downloaded terminal emulator and did the following
su
rm /data/system/batterystats.bin
I had drained it fully down to 1-2%, did the above commands, plugged it in and charged to 100%. You must be rooted to do it this way I would think since Im using su for superuser.
Yea, I recalibrate the battery on my 2nd flash. the first flash my battery was draining literally 1% per minute. So I reflashed (I thought something went wrong on my 1st flash) and recalibrated now it's normal again.
gocats7: Yup cog comes rooted
Cognition is awesome. With all the features built in, the att crapware stripped out I dont see myself ever running a stock ROM again. In regards to battery though, I think its at least as good as stock if not better. I havent had 2.2 beta 5 loaded long enough to really tell.
I've never had poor battery life. I did have that "new phone syndrome" when I got it and had to charge it a lot. But now I'm going around a day and a half on a charge with moderate use. I use wifi everywhere I can and try to minimize the time the screen stays on.

Have you found that wifi has been helping your battery life? When I have mine on I lose battery at ~5-10% an hour. With it off I lose 1-2% an hour. I have to switch it off nightly so that I don't have to charge my phone again in the morning.
Just the thread I was looking for...
I just recently bought a captivate that had the battery problems it seems so many are having with random shutdowns etc. I would get maybe 12 hours before getting the recharge notice. And that is with very little use. So, along with the advice from these forums, I had it replaced within my 30 days and immediately noticed a difference in the way the phone felt(if that even makes sense). It seemed like the screws were tighter, it was cleaner and it way out performed my previous captivate. Had me thinking I was given a display model or something.
So, to keep it short....I just plugged in after (for me) a very impressive 64 hour strech with moderate useage, some gaming and movie watching. Could not be happier with this phone right now. I cannot for the life of me figure out how such an impressive spec'd phone can use so very little power while locked. It makes me feel like a proud parent...lol.
I <3 My Captivate...

I have actually found my battery lasts longer with wifi on. I only turn it off when I leave the house. For me the wifi seems to be a lot more power/data efficient then my data connection. I can use the phone all day on wifi and still have 20% left at the end of the day whereas when I've been out all day long using data I can barely make it home without it *****ing at me to charge the phone.

I have had the best battery life yet with Cog 2.2 Beta 5.5 and migrating my Exchange server to Google Apps Premium so I do not need to use stock corporate email app anymore. I am pretty happy with this so far although I have only used the new beta for a day so far.
As a bonus, I am even using Live Wallpaper.

Mine is more like 7%/hr, which is totally unacceptable, I have all sync turned off, except exchange... with my HD2 running Froyo, I could do 2%/hr with the same settings.... I am still trying to figure out what's draining my battery...
I have also noticed high data usage.. I've tracked it down to T-mobile's AppPack. I've never used the program but it's constantly draining away my data... Is there a way for me to remove the app or disable it?
Thanks!
Get Watchdog from the Amazon appstore to find out what's draining your battery. I believe it costs, but it is a thoroughly useful app
Don't think we can remove carrier apps until we have root...that said, you could try adb pull, but I'm not sure whether it will have any effect. May need root for ab pull, in which case we can't get rid of carrier apps :/ sorry

this has the best battery life ive ever saw. I'm in 0ma all the time the phone yesterday lasted from 530 am til 7 pm at night with a lot of text and playing games like homerunbattle 3d. If you play that game you know how much of a battery hog it is. Best battery life. Battery was soo good i barely charged it went to work with a 40% battery and it easily made it through a day with moderate texting all day!!
Gotta say... coming from a TBolt this thing is like sex in a tin can.
Idle is 1-2%/hr probably. I would get 10%+ on my TBolt at times... if not more. It was bad.

today is the first time I'm having issues. Only 4 hours since charge & down to 40%. The Awake time shows as 99% of Up Time. Is that normal??? Also, anytime I look at the task manager it shows wifi calling running even though I have it shut off
I've got an Asian model sensation (ie. 3g and not 4G model ) and I find my battery isn't really calibrated properly so its hard to comment on average percentage drop per hour. I've recharged my battery 3 times already and i find the battery stays at 100 percent for around 30 minutes of constant on web browsing, then it will drop at a rate of 10 percent every half an hour with constant use and will fluctuate.
To report on a rough usage breakdown, with all background syncing disabled, I managed to get 10 hours standby before my phone dropped below 10 percent. This was with 5 hours of screen being constantly on doing mainly web browsing on 3g and one 15 minute phone call using my wireless Bluetooth handsfree.
I can report the battery life with constant usage is better than what i got with ny hd2. Running android ROM, it used to do around 3 hours of constant web browsing before the battery will fall under 15 percent. In standby my hd2 used to drop around 1% per hour, which was quite excellent.

Those are the stuff I'm talking about, it appears that one of the settings and/or app is constantly using the processor, which causes the phone to stay awake even when the screen is off... I just haven't figured out which app is causing the problem.. I am suspecting it is one of the Tmo apps.
I'm looking at a full battery life of 11 hours, 49 minutes with moderate usage (some calls, decent amount of texting, some games). I use the app/widget "Battery Left" to do its own independent assessment of battery usage and life.
So far the battery reminds me of my early days with my Nexus One -- before I had it rooted and optimized and undervolted. Once rooted and optimized, I saw a good 50% increase (at least in battery life).
If you'd like some relief right now (before we get it rooted), I recommend Juice Defender on the market. It turns off data (among other things) every now and then to save battery, and with this I can squeeze out 18+ hours with moderate usage.
how are you checking the percentage? when I looked in the settings menu, all I see is a long green battery bar, no actual numbers. Or are you all estimating from that?
I don't monitor my standby time, but I'm sitting at what looks like 40% after 13 hours of fairly moderate usage during the day, I'm impressed.
Ive been getting about 9 hours out of a full charge. Had to put my phone on the charger today at around 4 o clock because it was dead. I dont have much more info other than that. I will keep an eye on my processes over the next few days. I have only 3-4 cycles on the battery though.
To check the percentage of the battery life u have to download some battery widget in the market.. I.e smart battery monitor or battery percentage s.th like that...
Sent from my HTC Sensation Z710e using XDA App
You can also check battery level by opening Phone and dialing *#*#4636#*#* and then select Battery information.
I'm using Juice Defender and I have to say it really does the job : my Sensation lasts More than one day and a half (30min calling a day, texting, Android Market, Angry Birds...). Without the app running it would last a day (Angry Birds drains...).
Juice Defender says it is increasing battery to 1,53% and it is very close from reality.
I've been owning the phone from 24th of May.
I am loving this rom, but also having HORRID battery life, I am literally dropping 10% every 90 minutes with an extended battery.
27% Cell Standbye
26% Bluetooth
19% Display
Now I keep reading that these might be false readings, but I keep reading this as a response to those having **** for battery life... so maybe they are not false?
Anyone having good battery life show readings like this? Those with bad battery life, what are your readings?
I'm running the CM7 w/the 2.5 radio - I'm in a 100% full time 4G area, but seem to have worse battery life when the 4G radio is on, so I just keep the phone on 3G - if I need the faster data I can always turn it on and off.
I'm running the stock kernal, no overclocking or setcpu type stuff going on.
Would like to hear from folks running this ROM w/killer battery life, what are your settings, tweaks, etc. Please specify if you're running an MR1 or Mr2/2.5 version and/or running the latest OTA 2 radio that just came out like yesterday.
I just turned off my FB sync (I forgot about that). I don't have gmail set up to sync automatically either.
I'm going to do this procedure a little later today and see if it helps, this is for the EVO, but, ya know....
34. "Calibrate" battery - (1) Turn device ON, charge it for 8 hours (or until LED turns green), (2) unplug and turn it OFF, plug it back in and charge for 1 hour (or until LED turns green), (3) unplug and turn it ON, wait 2 minutes, turn it OFF, plug it back in, and charge for 1 hour (or until LED turns green), (4) unplug it, turn it ON, and use normally.
Anybody else try this?
today will be my first full day of work use w/this ROM so we'll see what happens.
Best to keep 4g off if not using it. Also, turn Bluetooth off when not in use.

i had horrible battery life the first day - then it got better. then i flashed mr2 official and battery life is really solid. getting like 15-20 hrs with 4g always on, bluetooth on sometimes. one important thing is having a custom lighting table which i will post later.

I have never, nor do I intend to ever do this. I got an extended battery for a reason. I can go all day and then some on the official roms, and all of the Sense roms.
I am not new to CM7, I have run it on both an Eris, and an Incredible. Both devices got FAR better battery life on CM7.
I am not complaining about this rom, or Slayhers hard work. I simply want to gather information so that we may help him trouble shoot.

This is exactly what I did lol, I had lost 10% in the first 90 minutes, now I am at 58% at 5 hours. I have been streaming google music for 2 hours of that 5 though. I would guess I should have seen an increase in battery usage, but have not.
The battery readings are wrong, I get a full day on 4G with my stock battery and see those numbers for cell standby etc. I use lean kernel though

do you see those numbers for BLUE TOOTH though? We know good and well some numbers are fake, but that does not mean all.
FYI I am now at 37% and 7 hours and 7 minutes... I have not used google music since the last post and I am seeing the exact same battery drain as when I was using it.
I have absolutely horrible battery life when I'm at work (which is basically a bunker). On a normal day, my battery will be dead within 6 hours just sitting there on my desk.
However, when I am at home (great 4G signal), I see my device getting upwards of 16 hours with moderate use.
I will also say that since I upgraded to the most recent radio, I have been having much better battery life at home. Additionally, my phone has stayed much cooler with the most recent RC + new radio combination.
I heard if you change the render fx to n1 calibrated, then you will get like 1 hour extra of battery life. You can change the render fx by going to cyanogenmod settings.
11h32m11s on extended battery 69% left
The other numbers have to be wrong. Theres no way cell standby is the number one battery user.
my cell standby is also showing 30% with the new OTA 2 radio.
I switched to dream kernel (have not wiped battery stats) and am now at 88% after two hours, that puts me at 6% per hour verses yesterdays 10.

only works for AMOLED screens.
edit: to be clear, it only saves battery on AMOLED.
so what i have found is that after installing dream kernel and messing with the governor settings... along with being connected to wifi. my battery life has improved tremendously. i wiped battery stats this morning after a full charge and didnt notice any change.. then i flashed the kernel and messed with gov. settings... after rebooting ive noticed a huge huge difference.. just my 2 cents for anyone who had battery issues like me
Yesterday I was able to choke out 20 hours while in a 4G area the entire time.
Running RC 1.2, Imoseyon's leanKernel extreme mode (extremely undervolted and OCd to 1.4GHz) and using the InteractiveX governor.
Also, I just happened to reboot and surprisingly it only took away 1% of my battery. Amazing considering whenever I did that on a Sense ROM, I'd experience a battery loss ranging from 7%-10%.

What settings did you land on as best?
cpu is set max to 368 mhz(very low) but i can crank it up if im doing somethign like playing games or downloading and want speed. brightness is at about 15-20 percent. the dream kernel and mr2.0 radio have made a big diff too. the dream kernel made the biggest. usually when id power off or reboot id lose 6-10 percent same as someone else i saw post. now i lose maybe 1 percent which is a huuuuge difference considering you lose 10 percent just because you reboot. also i try to stay on wifi wherever i go. on 3g i def notice it drain quicker, but i am no expert and there are a lot of people on here who by far outexperience and outknowledge me(my new 2 words) so im sure other people have some suggestions

I am loving this rom, but also having HORRID battery life, I am literally dropping 10% every 90 minutes with an extended battery.
27% Cell Standbye
26% Bluetooth
19% Display
Now I keep reading that these might be false readings, but I keep reading this as a response to those having **** for battery life... so maybe they are not false?
Anyone having good battery life show readings like this? Those with bad battery life, what are your readings?

That is strange I am also using CM7 with an extended battery and still have 41% left after 14:56 on battery.
battery use does show
cell standby 31%
phone idle 19%
android system 19%
wifi 11%
dialer 10%
display 6%
voice calls 3%
I don't know how everyone else is getting 3-5 hours of on screen time. When my screen is on, I lose about 1 percent every 2 minutes it seems like. When I look at the app usage, the kernel and media are sucking the life out of the battery. I am really discouraged about this battery because my G2 would easily get 3.5+ hours of on screen time. So far, I am going to be lucky to get about an hour.

Something is wrong with ur phone or u have some jacked up apps. I have got over 6 hours screen time with this phone and got over 5 with my DNA. You need to download GSAM or BEtter battery stats.

I have Gsam installed but sometimes it doesn't accurately record on screen time as it resets to 0. Also, today I unplugged my phone and the phone was thinking that the charger was still connected. As I said, Gsam reports that the Kernel is taking battery power.

Something is way wrong with your phone then.
Mine has terrible battery life
I am very much on the same page with you. I am on my 4th cycle.
Mine only last 14 hours with 3 hours of screen time. I don't understand how all these people are getting 5 to 6 hours of screen time.
I have both Better Battery Stat and GSam monitor and it shows Kernel is taking 50% and system is taking 6.2%
Just try with different kernals,good kernals would give exellent battery life
I would gladly take the battery problems to get rid of this brand new beast. It's too Frickin big.. I had g2 but sold it. Paid 700 for this att note 3...lol. straight talk on att towers to save on bills. But this thing may be the fastest latest greatest next to the new releases of '14 but I should have kept the g2...This is a tank. I'd swap for smaller phone in heartbeat. Might post cl ad

Are you in the right forum? This makes no sense.
I think it highly depends on what you're doing when screen is on. If you're playing games or using a lot of data, it can drain very quickly. If you're watching local videos or something, your battery would last a lot longer.
Im a beginner, xda said i must have 10 posts to do anything on xda so i was filling my posts..sorry friend....now i got 10 posts so im playing with n9005 rom section now
if you are rooted, install better battery stats (free on xda from the dev) to see the culprit.
clearly something is keeping the phone awake and hogging the cpu
So far today with only 10 minutes of screen on time and 45 minutes of playing a podcast through Bluetooth in my car the battery is down to 92%. This podcast was already downloaded and just playing from Dogcatcher. When I left I rebooted the phone right after pulling it off the charger. The phone is rooted and all Verizon apps are disabled. I see the android system at 40% and Google Services at 15% usage. Yesterday with only about 2 hours of screen on time I was down to 18% after 10 hours off the charger. I do not see any one app drawing power, it is always the android system it seems.
Edit: Using BetterbatteryStats I noticed that my phone has basically been awake the entire time it has been off the charger. Out of 2.5 hours it was in deep sleep for 10 minutes.
I don't get great battery life either. Nor do I get good game performance. Battery has went down 9% in less than 2 hours of idle. Just downloaded gsam the kernel use is the highest at 26+ percentage

Turning off Location Reporting made a HUGE difference to my battery life. I accidentally left my phone laying in bed next to me last night instead of plugged in, and it dropped maybe 5% over 6 hours.

I will try disabling location reporting. But I know with my Galaxy S3 I had this enabled and did not have battery issues.
I turned off location reporting and location history and am seeing better battery life today. 5hrs 47 min and 89% battery left.
My battery is confusing me. First 2 days.. 15hrs 3hrs screen on time.. 3 days after that 24+hrs with 5hrs screen on time... The past couple of days I'm back down to 14-15hrs with 1-3hrs screen on time. This is running it down to 10%
My usage isn't much different from day to day.
Power saving is now enabled and I turned off location settings. Let's see...
M8, nuff said.
What I do not understand is why my old GS3 and my co-workers HTC One M7 with location services on, do not have this battery drain problem. This should not be an issue.
Yeah, it seems to be an on and off issue. On my GNex sometimes after flashing a ROM I had to turn location reporting off to get through the day, and then after the next ROM flash I didn't.
