So, I recently cancelled AT&T but I wanted to make a couple of last remarks on a battery issue, so as to (hopefully) better inform the devs. Up front, I will say that the reception at my house is terrible (hence my cancellation). As such, I expect somewhat poor battery performance. I have run nearly every version of Cognition, tried the AOSP project, and most recently run Perception. After using these, I was left with the impression that the battery performance in all of these has been disappointing.
Having received my new phone and with my old service not yet deactivated completely, I decided to try a more formal test. I used the following test protocols in order to ensure a fair and accurate comparison was conducted:
1) The phone was positioned for the worst possible reception in my house. It was only moved to change ROMs and was returned to the approximate location it was previously in.
2) Each ROM was flashed at 100% battery, with SIM and SD Cards removed.
3) A battery recalibration was performed after each flash, as detailed in the Cognition thread (Charge to full, turn off, charge to full, turn on, use for 2 minutes, charge to full, delete battery stats). Following this I did one more complete discharge and recharge to ensure the statistics would reconfigure with the calibrated battery.
4) GPS and Bluetooth were turned off; WiFi remained on and connected through all test runs.
I loaded Cognition version 2.3b6 and then Perception build 3, both of which performed approximately the same. Leaving my phone on standby and with only very light use (0 answered calls and no internet surfing or messaging), I could get no more than 15 hours of battery power before it died. Following this, I restored my phone to the stock JH7 update and, as of now, my phone is at 54% after 2d 19h 25m of use.
I know many people have been flamed for daring to suggest that the ROM has something to do with the battery draining abnormally, but I did this test as objectively as I could so that the community of developers can use the information to improve on this issue. In my opinion, this test suggests that something in the custom ROMs is causing an excessive battery drain. While this may not be happening on everyone's phones, it is most definitely happening on two of my Captivates. Hope this helps and good luck! I am off to Droid X Land! Suppose I'll use my working GPS to get there! (Sorry, couldn't resist... too soon?)
Edited for grammar and clarity
Poor signal is the biggest battery drain. Especially in 3g areas. I have had phones on VZW and ATT (different times and locations) where my battery would not last 8 hours.
Another test to show it is not the ROM or OS is to put the phone in airplane mode and observe almost 0% battery drain overnight.
But since these custom ROMs are built off beta releases, I am not surprised by your results.

I noticed the same thing a while ago and am just hoping there is some issues with the fact that these roms are being developed on leaked builds without the source code.
The key thing to notice in the attached screen shot is the near constant 1-3% cpu activity when the phone is not being used. On JH7 I could leave my phone on over night and only lose ~3% battery. Currently on Perception build 4 I lose ~20-25% overnight. On Cognition 2.3b3 I lost about the same.
I get about 16 hours on my captivate with light to moderate use on the froyo leak.
on Perception and Cog (latest builds) I was getting about 9-10 hours with very light use.

I doubt the battery is your problem. As my test suggests, I am pretty confident that if you were to restore to stock, you would find your battery risen from the dead.
I can vouch for the OP about battery life. Battery life on JH7 is WAAAAYY better than any custom 2.2 ROM. I am running stock JH7 with Atimns v1.10 Voodoo kernel. Beats the pants off of the Cognition 2.3b6 ROM I was using battery-wise. In my experience, all of the Froyo based ROMs have battery issues. :-(
I just searched up a little bit more and found that the sensor is using a lot of juice because of a bug in the picture gallery app included in all froyo roms/leaks. I checked my sensor use and sure enough it was at 6 hours non stop. uninstalled using root explorer installed the Gallery3D.apk found on this site and now the use is at 2 seconds. I hope this was the cause. Also, is the android system supposed to be using so much of the sensor? My phone has been on for 11 minutes (reboot) and the battery history in *#*#4696#*#* says its been on for exactly the same amount of time...
sorry for the thread jack!

The issue with the gallery using the sensor has been known for some time. If you our the rom dev did not change out the apk, you should.
Well I changed it and my battery has been going great! Heavy use with 5% decrease per hour since I replaced it.

To be fair...the custom ROMs I have tried each had WiFi set to always on. The stock ROMS from had is set to only be on when the screen was on. Depending on the availability of a WiFi AP, this can make a huge difference. Looking for a WiFi AP to connect to is costly.

In my case, this was not the difference for me. I always had my WiFi always on, even with the screen off. I turned it off manually if I know I am going to be some where WiFi is not available. The battery drain is definitely somewhere else....but these are leaked Froyo ROMs for a reason.

It depends. If there is a lot of data transfers going on and WiFi is off with the screen, these transfers will take place over 3G, which in more cases is not as power efficient as WiFi, all else being equal.
I'd say, WiFi always on is better, in my experience anyway. Mileage may vary.

For me personally I get terrible battery life when wifi is on. Everyone on here seems to say that leaving wifi on saves battery but this has never been the case with any device I've ever owned . And I'm talking about when I'm sitting home in an area with good wifi reception too.
I can't figure my battery out at all. On the weekends if I stay home and keep wifi on my battery will be on for 20 hours and still have 65% left. Once I leave home and I'm using 3G I can only get about 5 hours. I've lost 20% or more per hour without even touching my phone.
Another weird thing is under battery usage and "cell standby", it always shows time without signal at 50%. Never more and never less, always 50% exactly. Any ideas?

Wish I had the answer for this too. Mine says the same exact thing. Always 50% yet I always have signal where I am. I'm hoping it's some sort of miscalculation and not a major bug where network connections are being dropped constantly and not being shown.
I get three+ days with my phone...
Sent using smoke signals.
Man, I thought I was in my own boat. Same exact symptoms across Cognition, Perception, Axura, you name it. Something weird though is that the first day is always great on battery, then after a night's charge it goes back to the 12 hr max per day (moderate usage). On stock it definitely lasts a lot longer. can't wait for an official froyo release... especially now that I have to use Good Messaging, another huge battery hog.
Ok. Android phones are not blackberries, and I'm well aware of that. This Thunderbolt is not my first android device, so I am very familiar with setting it up and using it in such a way to make the battery last.
I'm not posting this to complain of the battery life sucking. I'm complaining that the battery is fine one day, and horrible the next.
So here's what happens. Yesterday, i unplugged my phone at 730am like i do every day. By 3pm with light usage, i was down to 40% or so. Charged it up before I left work, no big deal, lasted the rest of the night.
Today, unplug the phone at 730am, phone is completely dead, as in, won't even boot by 11am. Same apps, same usage, same location, same strong 4G signal, same everything. It has happened multiple times on consecutive days when i was rooted on the stock rom, and still on VirusRom. I just dont get why this happens. I am doing nothing different and my phone either lasts all day, or a few hours. It's getting to the point where I am finding it very hard to rely on this phone when i'm out and about. It makes no sense. Especially if i'm not really using my phone, just checking for texts once in a while, there is no reason why it should die. What if i need it? I couldn't even call or text my gf tonight while I was working because my phone battery was ZERO only a few hours after leaving the house with a 100% charge.
Is anyone else experiencing this?
yesterday I had abnormal drain on my battery. I get 18 - 24 hours on a charge normally, but yesterday I went from 100% to dead in 5 hours. Called VZW and they said it was a documented problem and they were working on it.
IDK, they are pretty good about pushing updates. Also, yesterday I kept dropping out of data. bizzare....
I burned through the extended battery in 9 hours yesterday, really hope they figure out some better power management soon,
Switch it to 3G cdma rev.a and see if that helps. The 4G radio is always being searched for. I love the tb so I can deal with no 4G til they get the bugs out.

You have to use current widget and see how much power draw your phone is pulling. Then use system panel monitoring to track apps using the highest CPU.
Definitely an issue and I'm glad that Verizon is aware of it. I've had this unusual drain happen four times now, all on 4G. Last time I noticed it (seeing the battery percentage drop like 2% every five minutes or so), went to the Market and snagged System Panel.
The offending process is "system." Had my CPU spiked at 100% for over an hour before I rebooted, which does fix it, at the cost of another 10% of your battery, of course.
Hope they get this ironed out soon. Love my Thunderbolt, but this is a major issue and seems to be happening to a lot of people.
The best thing to do is dial *#*#4636#*#* and turn the radio to CDMA auto (PRL) mode.
I am already seeing much better battery life, as I am in a non 4g area.
Thanks for the suggestions. I'll have to give that a try. I got into the radio settings, and after flashing VirusRom, my phone defaulted to LTE mode only. I put it to cdma/lte auto, to see if that helps. If not, i'll just disable LTE unless i really need it.
No need to dial all of that crap. TeamAndIRC has a toggle app called "LTE OnOFF TeamAndIRC" that allows you to toggle between CDMA and CDMA + LTE/EvDo auto.
I found out two things dealing with my massive nighttime battery drain. One, wifi doesn't seem to work correctly. I've never had the problem before but for some reason it doesn't sleep correctly. What I've done is changed the sleep policy to "15 minutes" which allows it to switch back to 3G fifteen minutes after I turn off the screen. That allows me to have wifi while I'm using it but 3G while it's idle. This has seemed to fix my problem along with... Second, I am on the fringe of 4G/3G here on the outskirts of Cincinnati. At work I am solid 4G but at home it can't make up it's mind. Well, that has certainly played into the battery issue as it is constantly searching. So, what I do is as I walk in the door from work I use the app listed above to switch to "CDMA auto (PRL)" and it sticks to 3G. When I get to work I switch to "CDMA + LTE/EvDo auto".
So, to summarize:
I have eliminated my nightime drain by doing two things:
1) I use the Y5 app to automatically start wifi as I walk in the door but have changed the sleep policy to "after 15 minutes".
2) I use the app above to switch from 4G/3G auto to 3G only.

LTEonoff is just a shortcut to the menu. In essence, it saves no time because you have to download it. If you're flipping it on and off all the time, then yeah, it might behoove you to just dl the app. But, as a one time thing, it's unnecessary.
^You are correct. I switch daily but I didn't see earlier that you were not in a 4G area.
I would highly suggest this to anyone who sees their data connection switch back and forth as I was in my house.
Battery life has been strong the past couple days now. I haven't had any unusual drains since i switched from LTE only mode to EVDO/LTE auto mode. I dont know if this was for sure the issue, but it seems to have made a huge difference. I haven't been plugged in for 2 hours and i still have 92% battery left.
Here's my interpretation of the issue:
There seems to be some kind of problem or bug with the radio which makes it drain an enormous amount of power from some towers (700mA+ is shown on current widget). Even with good signal, I'll repeatably drain a lot of power in certain areas. The "fix" is to disable mobile data or switch to wifi. This lowers the power usage back down to (slightly lower than) normal levels.
For some reason, the radio will not admit to drawing practically 90% of your battery in the battery use menu (nothing does, in fact ... it just looks like normal battery use).
I'm glad to hear that they are aware of an issue that maybe causing this.
I can't stand the battery life either other than that I love the phone

Yeah i'm still at 83% battery after being unplugged for 4 hours, light usage.
Another thing i noticed is that when my battery was draining stupid fast, the phone would be warm to the touch even when it was just sitting on my belt clip. All seems well for now.
Mine is good

My battery life has recently become terribly inconsistent. Last week I was actually getting through a 16 hour day with light usage, but this weekened I must have installed something because now the phone is lasting 3-4 hours with hardly any usage at all.
The battery information is pretty worthless because it's not showing anything except display using the battery and the display has only been on maybe 8 minutes.
Checked the partial wake info and nothing seems to be running in the background. The battery is just discharging like crazy all of a sudden. Guess Ill start uninstalling stuff to see what might be causing it
I am also having a weird battery experience today. I am rooted running Adrynalyne 1.9. Last few days I was doing great, moderate usage and was staying charged for 16-18 hrs. Today my phone has died twice during my 8hr shift at work. I KNOW something is wrong there. Hopefully a fix is found soon.
On all my Androids (4 of them currently in daily use), I've found that Words With Friends is often a HUGE battery killer...and I don't mean because you play it a lot, I mean leave it running and put your phone down, walk away a while, come back to the phone and it is HOT to the touch! Obviously killing the battery. Something to look at for sure.
I've got the extended battery and just went over 48 hours, with moderate to heavy use by my standards on a single charge. Pretty amazing and I guess I'm not in a bad radio area.

The only thing I love about the TB is the 4G...everything else on it, been there, done that. I wouldn't keep the TB if 4G had to be turned off to make it usable in terms of battery life. Hopefully it will be fixed quickly!

Thanks for that analysis. With that in mind, if it's accurate, could a Tasker app profile be set up that does your fix if the drain works that high? Would be a nice safety feature for those who aren't willing to have to look at their phone frequently to check battery life.
You have to use the current widget to record your idle power readings, its the only way to know what's going on. Then use system panel monitoring to see which app CPU is highest.
I896, Rooted, factory Gingerbread.
I have a Captivate and a Tab. Both Wifi only, no Sims, Airplane mode on, Bluetooth off. Machines are on but screen is off. The Tab looses 3% over the course of the morning and the Captivate looses 20%!
I'm running regular 'power user' type apps; Titanium Backup, Tasker, LauncherPro. If there are any apps notorious for secret batt consumption, let me know what to avoid.
Running SystemPanel Lite - I can't see any app that is taking up more CPU time than normal that would explain this kind of drain. The battery page shows a good proportion of battery use display and wifi. In one instance I used the Captivate so little that display showed less use than wifi. In the course of just checking phone power consumption, the display use percent way up, just like expected (Just to show that wifi was really doing almost nothing) and still I had lost more than 15% of battery over the time when the phone was supposedly idle, not connected to anything with the screen off. Some ghost is sucking the life out of my battery. Grrrr. What could it be?
I loose 30% in a night with wifi off, backlight set to absolute min and nothing runninng or syncing.
I don't get it. Any ideas? What do I try next?

His tab is running Android too.
If you don't have anything helpful (or knowledgeable) to say don't say anything.
Op, download watchdog from the market, (system panel is kinda ..meh.) and see if there us a rogue app munching battery.
You may consider flashing a ROM see if its just that firmware/kernel reacting to your phone.
Have you tried Juice Defender?
Also, check to make sure you don't have applications constantly running. What version of android are you running? Check in system settings -> status -> somewhere in here you can check the battery status and what applications are pulling the most juice ... From there if one application needs to be removed you can action it ...
Also try the "Battery Calibration" app in the market. It's free.

my captivate running cm7 STOCK will drain down to 20% from being idle for 12 hours
my battery will also drain 30% from 45 mins of wifi only use.
doesnt help him but thats my experience from my captivate

Set it to when screen turns off.
We have to switch that every time we flash. I really wish it was default. Some ROMs also have background data control, but it's usually when wi-fi is on so it shouldn't be a problem.

You do know that cm7 doesn't have the proper hardware drivers from Samsung so the battery life is known to be HORRIBLE right? If not you should really read up on the ROM you're using
Flash any touchwiz ROM, especially a native I897 build and you will see a dramatic increase in battery life.

http://forum.xda-developers.com/showthread.php?t=1364357
I've held off replying as I was trying a few things and figured I would report only once I was done.
I found and ran Battery Calibration, just before I read the post. Between that and turning Wifi sleep policy to off with screen off, I had a great weekend. I was getting a day and a half out of my phone, which considering the use, was very acceptable. I was getting about the same drain as my Tab. I had 1% battery drain after 4 hrs of screen off time. That seemed fine for me.
I got back to school where I teach and yesterday the phone drained as fast as it has before. Interestingly, it continued its rapid drain even after I left the school and went back home. So, it died at 4am this morning. I heard it shut down. The school has at least 4 routers, two of which have 5k access options. I know if I choose them, my laptop drains way faster. Is there a way to limit my wifi connection on the captivate and not use the faster 5k connection?
But, this still doesn't explain why, even after I leave the school, the Captivate continues to drain when it is 10ft from a single 100mb wifi router.
I'm almost ready to try a custom Rom, but not sure how that will affect my ability to use it as a phone, once I get my Sim activated. Still new to this all.
You think everyone running a custom ROM doesn't use the phone?
Shouldn't affect your ability to do anything...
The WiFi and cell radio do increase power on lower signal as we know, but that's not always the cause of drain. I remember times using Froyo when kswapd goes nuts for no reason, or trillian, email, twitter or some other app just starts using massive CPU. Many apps are probably never tested on a system that has no connection most of the time. That's where all the utilities come in handy to find the culpret. OSMonitor can help find CPU hogs. TiBu can freeze apps, or uninstall them temporarily. Juice Plotter can monitor drain over time (newer Androids have something like it built-in). It takes some time to find it, but newer versions of the OS make it easier and have less trouble.
Also the battery % is only estimated. I'd trust full to empty time rather than 90% to 80% time as 10% use since it's not really as linear as we think.
Not to point out the obvious, but it can be the battery itself that has the problem. They aren't exactly manufactured to NASA standards... well, maybe their standards lately, but the point is, sometimes the ghost you're chasing is staring you right in the face.
I heard good reviews about battery life of Moto G but mine's battery life is disappointing, could you please see my stats and tell me if its normal or something is wrong.
There can be many factors why battery life is that worse. Bad programmed apps, Wifi always on, screen time, call duration, running background processes and so on. Most times i switch my data connection off if i don't need it. I run my phone since 2 days and 8 hours and my battery is on 9% at the moment. As i see your wifi was always on. Try switching it off.

Screen on time is around 4 hours, I haven't called even for a second or used my data connection yet, but I keep wifi always on because I thought it causes lesser battery drain.

Don't know, sounds unlogical to me.
4 hours screen on? Phuu........did not try it but i guess it is normal if you have your screen 4 hours on.
What are you expecting? Switching everyting on and then have a two days battery life?
See yourself on your graph how battery got better when screen was off. Now switch off wifi and try again.

I thought Wifi uses lesser battery than 3G and I expected 20 hours battery atleast.
I see your Wifi is working all the time. Are you aware of this?
In some JB Android version google implemented automatic Wifi networks scanning (probably for their purposes), even when Wifi switch swhows "disabled".
You can disable it, maybe it can save some battery: http://www.pcmag.com/article2/0,2817,2422689,00.asp
Cheers.
Install BetterBatteryStats and see if there's any wakelocks that are eating your battery at the moment.
Also, about your on screen time - what's the settings for brightness that you use? You might want to consider dropping the "auto" and go for a reasonable low level of brightness that fits your indoor or outdoor activities.
Your assumption of WiFi eating less batter than data connection is correct in most of the cases.
Anyway, if you have any doubts about this... an average NOTE3 user can't get to those 3h 30minutes with on screen time

Im currently on 1d 18h and have 39% left with 4 hour screen time and that's with a mixture of wifi and 3G.
i enable airplane mode overnight though which only uses 1% in 8 hours.
I'd say that's normal battery life for this phone here's mine for today.
I'd agree with the previous post.
I've been on a WiFi network for the past 7 hours.

Battery life has been disappointing ever since smart phones got on the market... Oh good old Nokia 3310 how I miss your battery performance
Seriously something needs to be invented, this cannot be tolerated any longer.

LOL. I miss my old Nokia too but face it. That old Nokia had a tiny screen and did little more than phone calls and texts.
I've had a few androids and The G is by far the best in terms of battery life.
I miss my indistructable Nokia but I wouldn't go back

Motorola is advertising this phone as all day battery phone so shouldn't it last more than 12/14 hours.
A car manufacturer also advertises his car with 500 km per full fuel tank. But if you drive all the time with 170 km/h per hour over the highway then this statement can also not be applyed anymore. As i said, i switch on wifi only when i need it and thats the same with data. I had a battery life for nearly 72 hours. Ok i made also less calls in that time. But it is all about your usage. I for my opinion can not find any problem as i said already. Motorola advertised nowhere that you can use your phone under "full load" for a whole day. This is called marketing in todays world. If you be believe everything what advertisement says then you seem for me very naive....... you should think about that

Atleast the reviews said it last more than a day and I didn't used the phone under full load, just the Wifi was on all the time which uses lesser battery than 3G and I did 0 calls.
It might be true that 3G uses lesser than WI-FI, but what is that for a comparison? You can not compare WIFI and 3G because it is a completly different technology for different purposes. 3G Data uses a lot of Battery that's true. But WIFI also but less than 3G. But this statement doesn't mean that WiFi uses nearly no Battery. It uses only less. If 3G uses 100 parts energy and WiFi uses 85 parts energy out of 100 then it is less. But 85 is still a lot out of hundred. I quoted full load, just as a general statement. I know you had not switched on Bluetooth and so on. But anyway, Dataconnections are a expensive feature in relation to battery life.
Did your review tell you the exact conditions they tested it under? Or did they just say that without any proove? Also Tests and reviews are often copy and paste bull****. If i see an Antivirus test and the Userinterface is tested bad but the userinterface has a 45% weight in the all over test then i would say this is a crap test.

Yes see the gsmarena battery test I've attached, my phone doesn't even come near to its battery life
Unfortunately I can't take a screenshot but I have a stock (not rooted) Moto G that loses excessive amounts of battery with Aeroplane mode on!
What can possibly be causing such excessive battery drain - 50% -> 7% in 6 hours with no screen on or data or wifi.
Thanks

Hi that's a lot of drain i'd say theres some rogue process that runs even in airplane mode with no internet killing the battery i'll attach a screenshot of mine from last night this is with network on but WiFi and data off.
Anyone else experiencing this? Atrocious battery life post upgrade. Nothing odd running in background, program or processes. Rebooted phone. Started the day at 100% with moderate usage at best, I'm already down to 19%.
Battery life is relatively unchanged in mine after the mm update. Easily make it through the entire day with 50-60% battery life remaining. I disabled a whole bunch of the bloatware (and will be removing it entirely when I decide to root my phone) and battery life is wonderful.

Mine has been fine, slightly better with doze/disabling packages. Do a back up through Smart Switch and try a factory reset. I do that every time I update.
I'm envious of your successes. I'll give it a bit to see if it stabilizes, if not I'll use SS and reset/restore.

I will recommend "Package Disabler Pro" to disable bloatware. Costs but is worth the cash.
Mine went through on Thursday and so far battery appears ok.
I have noticed however the lighting is messed up all over. Play books night light feature is broken and dims it to unrecognizable levels. I have to go into the settings again when in the book and disable auto lighting and manually raise it. When back at the list of books screen, the brightness drops to nearly off again.
Also it seems the notifications when listening to music are much louder. I could listen to mp3s via poweramp while reading a book and get an SMS text and itd be a light little sound. this is playing louder than my music and very annoying.
My batter life was horrible after the upgrade. Here's what I did to fix it.
1) Wifi sleep policy - Changed that to "While Charging" (big difference noticed after that)
2) Fully charged phone then let it run down to 0 (must let it power itself off)
3) Wifi Scanning has been moved under Location setting. Go to Location -> Improve accuracy, make sure Wi-Fi scanning is off.
Batter life is awesome now.

1: Apps/sync will use mobile data as priority if this is done while waiting to connect to wifi. In turn, using even more battery if an app/sync wakes the phone switching between networks.
2: This is damaging to Li batteries. To extend the life of your battery, it is better to keep it topped above 80% and cool(not very common in real world applications). These aren't Ni batteries, long gone are the days of "memory discharging".
If you don't need notifications at night, use airplane mode. I miss Xposed, Autotasker, and Amplify(formerly Bounce)... Greenify is a good alt atm
Note: Sometimes even Play service updates will introduce bugs and or "retarded" policies that will destroy the battery, especially the "Now" systems. It can happen at the most random times as well and not at all most. Every now and then the fat man will get stuck in the tube.
All thoughtful replies. I don't have Location on ever, unless I'm using Waze, so that's a non-issue for me. Allowing WiFi to sleep when the phone is off, while I'm only connecting via WiFi, effectively makes my smartphone a dumb phone, until I wake it up, right? The fact that I need to start changing around "normal" settings on my phone, to lesser benefiting ones, to get back to the battery life I had before I installed MM is pretty silly. I've been hoping things would settle down, but they don't. I can try using SmartSwitch later to see if that helps.

No, it will connect LTE and then switch to wifi. LTE use more battery life, the network switch uses a bit, then finally you are into wifi. If your phone wakelocks or alarms(location ping, play service ping, etc) it will use more battery than wifi always on. Personally, I've tested both to make sure a wifi wakelock bug hasn't been introduced as I do with every update and play service update(it does happen and it's horrible drain). I see more savings always on.
If you meant you disable mobile network, yes, dumb phone, text and call. Also, I disable mobile usually always as I piggyback off work cell at work, and always wifi at home. I only toggle mobile data when necessary.

I believe this is what most people encounter. Most dont have unlimited data and use WIFI always. I think by default, WIFI is set to always on, even when phone screen is off. WIFI will rape your battery. I did my own tests with wifi vs 4g and just by using my 4g all the time, battery quadrupled. Many argued that WIFI uses less battery, and i have the best of the best wifi router/modem/isp with 5ghz ac excellent coverage. Not the case for me. I have unlimited and just stick with that now. Battery life on MM has been great for me.
My battery life is 4x better. I couldn't be happier.

Been on MM for about five days now and my battery blows, so much worse than what it was!

Mine is exactly 4 times worse
Battery the same.
But I have to tap the screen harder to chose app.
Going to factory reset and start clean, been a while.

Not that I know of.
Though they JUST released Marshmallow. Verizon is probably still patting themselves on the back even though they released several months late. What I'm waiting for is a miraculous root.
I never use my phone the same amount every day, so it's hard to say exactly what kind of battery life I get, but I have noticed that it has improved. I would usually be near 15% by 10pm after coming off charger at 6am. Now I float around 25% at 10pm. So it seems to be better, even if only slightly so.
I see a minimal improvement, but I was doing what I could without root prior to sleep unnecessary crap.
Weird, when thye MM updated happened, up until the last two days, I was getting much better battery life under MM. But the past few days my battery life has declined dramatically to the point that I am not getting through a day of minimal use. Screen only 2%, Android OS consuming 76%.
I just fiddled with settings (Changed Wifi sleep to While Charging; Turned off wifi scanning). I am going to also try a reboot to see if that helps. I swear it started just about the time I started looking at Nexus 6p replacements).
Update, rebooting, and removing a few more useless apps and battery life has returned.
