Battery Life - screen on time & battery conditioning

Firstly let me say I'm a long time lurker of XDA, I don't often post but rather keep quiet in the shadows. I've owned many handsets (Including the Inc. and TB, meaning I know bad battery life) and this has always been the site I go to for hacking and general information.
I don't expect definite, for-sure answers. I'm just seeking some advice on this, I absolutely love this phone and a Nexus on Verizon has always been my dream.
Secondly, I'm not posting here asking why my screen uses over 50% of the depletion on my charges, it is supposed to, I know that. I see many threads asking about that, which is why I waited to post not wanting to ask what has been already. But I am asking about my case specifically, and want input.
The main thing here is the amount of screen on time I am able to get.
I have had my GNex since Saturday afternoon, when I bought it the battery was dead and I fully charged it, the first day I used it mostly while plugged into AC, using 4G to install my apps. Since then (the last two days) I have tried depleting the charge almost entirely before charging, shying away from charging mid-depletion. I have tried using CDMA mostly (my area has just marginally good 4G), hoping I could stop some of the bleeding, but to no avail. I should also say I yesterday for the first time threw a custom ROM/Kernel on and that seemed to help marginally, though in truth I don't see that really changing the screen power consumption.
Please take a good look at both screenshots, as said I care nothing about the %.
(I am aware there is still 13% remaining on my charge, but even so this seems just crazy)
In the first screenshot at the bottom it's apparent this isn't a huge amount of screen on time.
I would kill to get 4 hours of screen on time with this thing, heck even in the area of 3, but it doesn't seem to be in the foreseeable future as it looks now. I can get out 2 at most to this point, and that is on almost entirely 3G/WiFi with light/moderate data usage.
I really need to ask. Do I just need patience to let this battery break in? I hear some say this can be a week-long thing, but shouldn't I see some increase by now?
If not, do I seek out a replacement battery or could this be an actual defect of the AMOLED drawing more than it should?
Thanks for your help!

There were quite a lot of awake time during screen off if I look your stat.
Thats your problem.
Too much sync?
Mine can get up to 3 hours and 45 minutes screen on time, span into 2 days stand by, gsm version.

Good point, looking into playing with sync in settings and JD.
But while that accounts for the drop during the 10hr overnight period (20% of battery/83% of time), I still feel the draw during screen on (80% of battery/17% of time) is just insane, even given the AMOLED.

Maybe its a rogue app running in the background making the battery drain real fast. Try wiping and running the phone normally without restoring your apps and see if that will improve. I'm having the same problem as you but with the GSM version. I'm looking through my apps though.

Here are some of the usual suspects:
- Facebook for Android app (uninstall it and replace it with Friendcaster and change the frequency of update t less often will do the trick)
- Accuweather widget or any other weather widgets
- Whatsapp
- Viber
- Latitude (google maps) - Login to Latitude and then ensure you select the option where it does not report your location and then sign out of Latitude.

Honestly, I have the GSM version and I've rarely gotten over 3 hours screen time. It's the screen. The battery life sucks, so you'll have to just ABC (always be charging), at the desk/sofa/car.
What I really want to ask is how you got the battery percentage inside the battery icon?!

This is also my exact problem. I can get great life if I don't touch the phone. Every time I use it for a few seconds, that's 2-3% gone. Browse the internet for 15 mins? Forget it, that's 10% gone at least.
I guess it's just the price to pay for such a gorgeous screen.

The custom ROM I'm running had it as the default icon: AXI0M 2.3.

What is your total screen on time during those charges?
The only app in that list I really have to check is latitude. Doing so now.

I think op should stop playing wind up knight in his sleep. Case closed. Just kidding. But seriously, probably got something using up cpu cycles when using phone and not using it. If i dont play any games, i easily get 4 hours screen time, and got 5.25 over the weekend.

When I flashed this ROM I purposely left games out when setting it back up, the only one is Drop7 which I purposely make sure gets killed when I'm done. All apps which sync I have either at minimal amounts or off entirely.

Are you in north america? Try ugkk7 radio maybe? I am in the usa and xxkk6 was ok, but since i flashed ugkk7 reception is excellent. Oh wait. Youre cdma version. I dont know if the same applies. I do know radios designated UGxx# are north american.

you could install CPU SPY to see if your device is going in deepsleep, I had a problem that one app was using most of the time 350mhz and was using my battery very fast.
after that i found the app with battery monitor and disabled the app to see if the problem was solved, and that was the case, and i have now a battery life from more then a day instead of 5 hours.

I can get 3.5 hours of screen on time spread over ~36 hours or so on the GSM version.. if LTE is on I would assume around two hours of screen on time was normal for a Verizon version just because of how LTE is but it did look like your CPU was awake a lot as well so also it could be a rogue app, not necessarily a game.

Will give that a try. Like mentioned though almost none of that time was 4G enabled. (Maybe 10mins of that first green section.) The slope is just as steep.
In truth this was a fairly data-light charge.
Could it be the rogue app would actually sap battery only when the screen is on? Even though there is wake time where there shouldn't, that isn't the main area of drain.

Galaxy Nexus Battery Fix

Hi,
I just got my Galaxy Nexus, flashed with AOKP build 18 and i gotta say that the battery life is unacceptable. It drops 10% in less then 1h while the phone is sitting there doing nothing. Wifi, bluetooth, location services, GPS are off. All background apps closed.
It lasts about half the time my iPhone 4 does and it is a year and half old.
I see some people showing examples of how their battery last for more then 20h but all these are BS tests as they leave the phone on standby all day or have some very light usage.
Is there a real fix for this? Am i forced to drop another 50$ and buy Samsung's 2100mh extended battery?
btw i tried setCPU also to lower CPU to minimum when in standby but doesnt do much. I want a solution that will enable me to use my phone, not something that makes it last 40h in standby and then kills it in 2h when i use it.
please help!

So everyone that posts four hours of screen on time is bullshitting? Did you know the first 10% isn't even that accurate? If you're on Verizon turn off LTE. If you're on GSM and you don't get three hours of screen on time you have an app that is killing your battery. It is as simple as that.

Try toggling Bluetooth on and then off, then grab CpuSpy from the market and check out if the CPU is pegged at a certain speed.
Some builds of ALL the custom ROMs have had issues where the phone wont sleep correctly, high %-age of Android System process, etc.
I disagree that its silly to talk about idle time on battery, because idle time is the closest we can all get to apples to apples comparison. We all USE our phones differently, the closest we come to using them the same is when they are just sitting there idle (not quite exact because some people sync data, some people only have 3G, etc, but a lot closer than person A playing games for 3 hours at a clip vs person B browsing for 3 hours)
I *still* havent seen anyone come up with a template like setup to report battery life. Like you said it does me no good to know someone dropped 3% "overnight" without knowing how long "overnight" is, if they had 3g/4g/Wifi enabled or even disabled completely, sync on/off, etc.
Personally, Ive seen 1.5%/hr drop with my phone idle. Running AOKP b19, LeanKernel, interactivex governor, undervolted (-75 mA at each level from 180 mhz to 1200 mhz), 4G on, BT on, GPS on, sync on (1 gmail account).
I imagine with all that stuff running 1.5%/hr isnt half bad. Screen on time isnt incredible but its not bad, but again my screen on activities can (and probably will) be different than your screen on activities so take that with several grains of salt.

It's not the first 10%, it's all the time.. it drops for about 10% or more every hour. Less then 3h of screen time.
I'll give cpuspy a try and see if some app is killing my battery.
I used AOKP rom because most of the people in the thread were saying that rom fixed their battery issue but for me it made no difference.

Yea somethings not right. Off charge at 8am and its 4:30pm now. Got 61% left at time of this writing and been using it quite alot. Typically have about 75% left about this time.
I just use an AOKP like yourself and a custom kernel. I'm on the phone like every 15min reading emails, SMS, word feud, twitter news, Facebook, Gmail.
LTE EX Galaxy Nexus - AOSP KANG
Asus Transformer - 3.2.1 OC/UV

It's actually 2000 mAh not 2100 mAh.
You can use a custom kernel such as Franco Kernel. New version came out today and includes more battery improvements (according to changelog!)

As you can see, if my screen is on the graph drops, when it's off the graph flattens out and the battery barely moves. I used to be sick to my stomach of the battery life until I realized it was because I wouldn't put the phone down and always had the screen on thus killing the battery.

Just a word of advice. Whites consume more power on AMOLED screens. You'd probably maximize your battery a lot more if you went back to a "Ice Cream Sandwich" feel or at least apply a black themed MIUI.

I had something similar and it was recommended to me on these forums that I log out of Gtalk.
Before people come out and say it makes no sense - it doesn't really matter if it does or not - it worked for me. I get a full day out of a charge now, which doesn't really matter because as someone said above it's all relative. What DOES matter is that my phone is now sleeping properly, so the battery doesn't drain when the phone is idle. That's the part that wasn't working on my phone.
If you feel so inclined, give this a try and see if it works for you. Just log out of all Google talk accounts and see how your battery life is - you'll know within a day if it's helping.

Have you flashed the new radios yet?
You can also try different kernels and see which one works best for you.

Ah okay.
I think MIUI is pretty much at the same state as CM9. Just lots of work needing to be done since ICS revamped Android in so many ways.

not quite.
can i preface by saying that there are two types of Gnexus's out there? the SCH-i515 (CDMA/LTE Verizon) and the GT-i9250 (HSPA+, AT&T).
The 2000mAh is for the HSPA+ version
The 2100mAh is for the LTE version.
i see a LOT of bad advice on these forums here.
my best advice to you (from one Verizon Nexus owner to another), is to keep at stock 4.0.2. Root it, and apply a custom kernel. Only apply custom kernel if you feel that you're still not getting decent battery life for a whole day on 4G stock ROM/kernel.
As far as I know, Verizon Nexus owners' max on-screen time with 4G enabled all day is about 3 hours MAX, and thats if you disable everything else but LTE, with very low brightness settings, and on extended battery.
imo, the next 4.0.3 or 4.0.4 update hopefully will mitigate some battery consumption issues.

You are using the HSPA+ version of the Nexus. HSPA+ version gets better battery life.
Try being on HSPA+ the entire day with wifi disabled. you will not be getting 4 hours of battery life on-screen time.

I think the Kernel is what makes the difference. It seems to be the only difference i see between myself and the people like you have a reasonable battery life.
which one do you recommend? And i'm a noob at this so could you point me to a thread the explains how to flash it? If u cant its ok im sure i can figure it out.

[Q] Official ics

Hello.How is official ics(4.0.4? on the nitro hd? Is it better than gingerbread in performance, does it have better benchmark results than gb,better battery, is video playback smooth, is the browser and gaming smooth? Would anyone want to go back to GB?BTW if i update does it have any result on the screen?Asking cause im not sure to update. Thx for the answers.

I'm sure no one would go back to gingerbread here, benchmarks don't really matter. Stock ics is super smooth. I just don't use it because atm there are better roms available like hono full throttle and cm10 preview.

features vs battery life
I would go back. I can't stand half time of battery life regardless of all ICS features. I already got "double capacity" battery from Amazon, but still it's far from GB longevity on stock battery. There are other ROMs, but you need to root the phone and install some kind of CPU Sleeper app. In my case Android OS consumes 40% of the juice and is awake most of time. In GB the major consumer was the screen and I can afford it because the screen is nice . Here in ICS they fixed it by worsening Android OS power consumption Not good improvement at all.

Did you do factory reset after installing ICS update? You should if you haven't.

I did factory reset (remember the other thread). It improved the life but not too much actually...

I don't know how you guys are getting bad battery life with the official ICS.
I've been averaging 15 hours of battery life on the official release with pretty heavy use throughout the day... I can provide a screen shot of my battery use screen if desired.
I'm also using the stock LG 1800 mAh battery, and not an extended battery.

I had a chat with AT&T support and folowed their instruction: Do factory reset, DO NOT RESTORE ALL APPS, only restore/update preinstalled apps, install/restore other apps one by one to find "incompatible" apps.
During first 6 hours after reset with only preinstalled apps it was ok. Then I reinstalled Yahoo Mail to sync address book. It also was ok. Then in 3 hours I installed WhatsApp and that was not soo good. Going to stop it and check if it is the problem. May be uninstall is better. Not sure yet. :fingers-crossed:
Also I'll put back stock battery just to do not compare apples to oranges

As of right now, I would gladly go back. I have an extended battery. Before the update, I regularly got 1½ - 2 full days with moderate to heavy use. No longer. Last night I unplugged my phone at 2 am with 100% charge. Eleven hours later, it sits at 23% with no usage other than 2 short phone calls, 4 or 5 texts, and no gameplay or other usage. Factory reset or no, this is just plain pathetic. I'm pretty confident that if I had the stock battery in right now, I would be lucky to get 3 hours out of it before having to charge.
I have also had issues with lagging, especially while typing text. And finally, my touchscreen seems to be...."off." Touches no longer register completely accurately. Seems to affect the right half of the screen more than the left.

Something must have gone very wrong with your installation of the V20C official ICS.
Not only have I had no problems with my installation, but I also get much better battery life on rooted V20C ICS than on CM9.
Here is my battery usage so far today, on the stock LG 1800 mAh battery (not the 3800 mAh battery).

As of right now, I would gladly go back. I have an extended battery. Before the update, I regularly got 1½ - 2 full days with moderate to heavy use. No longer. Last night I unplugged my phone at 2 am with 100% charge. Eleven hours later, it sits at 23% with no usage other than 2 short phone calls, 4 or 5 texts, and no gameplay or other usage. Factory reset or no, this is just plain pathetic. I'm pretty confident that if I had the stock battery in right now, I would be lucky to get 3 hours out of it before having to charge.
I have also had issues with lagging, especially while typing text. And finally, my touchscreen seems to be...."off." Touches no longer register completely accurately. Seems to affect the right half of the screen more than the left.

Your phone is probably staying awake 100%. I had the same problem with the official ICS firmware. I tried installing it thought the official installer and using the flashable version through CWM. Factory reset and froze all the bloatware. Same problem with both of them. Phone stays awake almost all the time and hardly ever goes to sleep. I went back to CM9.

Well now I have new problems. Did a factory reset, and now every time I unplug the charger (car OR wall), the phone immediately shuts off. Juuuuuuust great. I wish I had NEVER done the upgrade. Shame on me for not waiting and reading about others' troubles first.

I've had no problems. Battery life is way better (hyperion 3800mah). Super smooth and definitely the best launcher out there. Sucks that telus deleted the themes though.

You might want to try forceably reflashing the ICS update. Perhaps something got corrupted the first time around or something, I don't know. To do it, you would have to follow the directions from the unbricking guide except use the Telus KDZ from here: http://forum.xda-developers.com/showthread.php?t=1838346 . Consider using a different USB cable if you have one just to rule out the possibility of a problematic cable that caused the flashing to get corrupted.
Unfortunately I have no idea why you would be experiencing the problems you're having.

OK. Thanks for that info. The factory reset has definitely left me with serious charging issues. Left the phone charging all night, and it only charged to 56%! That was with a solid 8 hours plugged in with the factory cable/plug.
Is there a particular reason I need to use that specific Telus KDZ? Just curious.

That KDZ is Telus's version of ICS. It's the same file that automatically gets downloaded by LG's updater tool if you use it normally. The problem is that LG in their infinite wisdom won't let you reinstall ICS because "there is no update available". The unbricking guide basically tricks the updater into applying the update anyway, but you have to manually download the KDZ you want to install.
You don't HAVE to install that one. You could also install Bell's or AT&T's ICS if you wanted to try it. But I don't think there's a good way to get back to Telus Gingerbead unless someone has a backup of it they can post. You could install a custom ROM though.
BTW, is it possible the problem is actually with the battery itself and it's just a coincidence? Are you using an OEM battery?

Didn't really want to go the custom ROM route with this phone...but I might. I'm on at&t FWIW, but I'm not opposed to another company's ROM. I do like several of the unlocking features and other visual tweaks of LG's ICS, but I don't know how the custom ROMs would compare in that regard.

Anything is possible, but it seems like too much of a coincidence. I'm using a QCell extended battery. It's maybe six months old at the most. With GB I regularly got 2 days on a charge with fairly heavy usage. Immediately upon updating to ICS, battery life dropped to roughly 16 hours. I didn't do the factory reset for roughly one week after updating, as I <stupidly> did not do any research before the update. Immediately after the reset my battery issues compounded with the slow/no charge and shut down on power cord unplug / reboot on power cord plug in. Sadly, my stock battery is 630 miles away. So I have no way of eliminating the battery as being the issue.

Battery life with 4.4/Sense 5.5 update

Hey all,
Just wondering how people are doing on battery life after the update. I moved from BoneStock back to the stock(ish) ROM, and I personally am struggling on battery life right now. It is early though and I'll make adjustments. Just wondering how it's going for everyone else.

May be hard to compare a stock non-rooted phone to a custom ROM even if it stock. Seems like every dev puts in something "for better battery life"
I'm stock, locked, S-On, 4.4 and my battery life is great. Though I'm comparing it to my old phone, Rezound, where I couldn't get out my front door without it dropping 10%
I make it through a full day no problems and I'd consider myself an "average" user.

I haven't noticed a huge difference, but Bonestock 4.3 was definitely better. I'm on NuSense which isn't stock but it's pretty close with a few optimizations. Are you checking in the stats to see if it's an app that's killing your battery? I've had a few occasions when Google location services killed my battery for no apparent reason.

I haven't spent much time yet trying to identify and fix the issues, but I'll start looking at it. I wonder what it is they do to improve the battery life in the custom roms...

I tried the phone back when it was 4.2 and battery was not great, could barely make it till end of work.
Now on 4.4 battery has improved quite a bit. Can easily make it til end of day. Btw I'm s-off stock no root.

My wife's on a totally stock version of the phone, with the latest OTA. I'm on Santod's odexed rooted version of the OTA. 3.11.605.1 in both cases.
We're both seeing a slight decrease in battery life, but nothing too significant.
It's hard to compare battery life because I'm constantly messing with my phone, playing games, changing icon sets, making and deleting widgets etc., while my wife uses hers for phone calls and email and pretty much nothing else. She's never installed an app. I was going to S-off her phone, just to have it done, but our daughter installed the first OTA update before I got around to it. (The 2.10.605.1). She's 9, and enjoys showing my wife how to do stuff on her phone. Stuff that my wife then enjoys forgetting.
Having said that it's hard to compare battery life, I'll do just that. She gets better life than I do, and could likely go 48 hours on a charge. Her biggest power user is the email function - which is the stock email app that came with the phone.
Battery Guru used to tell me I could go 32 hours on a charge, but after flashing Santod's latest ROM I had to uninstall and reinstall it, and so far it's not giving me the same projected life numbers as it used to. I don't mean it's projecting less hours, I mean it's not giving hours of life expectancy at all. I can't remember if it took a few days last time before it started giving the projections - I only flashed the ROM last Friday.
Before the update I would be at somewhere between 70-80% at the end of a day, my wife would be 80+%. Now I'm closer to 60%, she's in the 70's.
My battery life may well improve still with Battery Guru. Would it make sense to re-install it on her phone and let it "learn" all over again?

the 4.4 update is draining too fast.

I went from the 4.2.2 BoneStock ROM to the new 4.4 version and my battery life easily doubled. I can make it about 28 hours on a full charge.

battery in 4.4 is s*ck.

i would prefer 4.3 for the battery life.

I noticed actually better battery life for 4.4 on bonestock. Im running with the elemental kernel and underclocked it, also i have some tweaks in tasker that keep my phone pretty efficient. overall i'm seeing around anywhere from 15 to 20 hours of battery life with depending on how long i have my bluetooth on and other things like that. ill post a screen shot later when i get home of my actual times.

I am having the strangest battery drain 4.4.2. 6-8 hours with less than an hour of screen time

I text a pretty good bit throughout the day and my battery life seems to go pretty quickly:/ I'm completely stock as well no root or anything.....yet. I'm hoping once they get a root/s-off/unlock method out for the 4.4.2/sense5.5 software, that I can do a custom Rom and fix all that.

With pretty heavy use I tend to see between 6 and 9% per hour according to better battery stats. My screen on percentage is probably within 18 to % most of the time. I'm running rooted stock with xposed and a tweak to stock that allows me to select power saver mode in settings.

temporary fix:
-Settings->Data Usage->(dots)->Restrict background data (yes this does make it harder to synchronize content)
-wifi off (if you have more than one bar of signal)
That temporary fix boosted my battery from a days use to two days. I blame Verizon for wakelocking our phone.

Hi there! Well, I consider myself an average user. Take a look at the screen shot. Numbers talk the best
BTW my SGN II gets about 5 hours of screen on time and has much bigger battery, so I'm happy with what I get on my One running 4.4.2 with sense 6.0 by hawk and ecliptic team powered by Lunar Ellie oc.

I think this should be the best phone for last year. S4 is overated for me since they have added a lot of stuff that we do not really use. here with my HTC one, it is customized the way we use it. And I can say the best part is that my battery can last for a day if my internet is off. If I'm casually using it with internet, it can run for almost 8 hours.

[Q] Battery Drain

Is anyone experiencing battery drain? I'm getting through a whole day on light to moderate use but I believe it should be better. It's seems to be draining during times when I'm not using it. I turned off the connection optimizer and got about 7 to 10 percent back but I'm still seeing drain that I shouldn't. I'm not using many apps beyond stock. Power Screen says most of my power is in "Android System" usually in the 25 to 30 percent range. Problem is android system is like 30 services. I may just root and start freezin stuff with titanium until I find the culprit. I'm just curious if anyone else has noticed worse than expected battery life

Yeah I've seen android system at the top of the usage list everyday and don't know why. I get about 5 hours screen time but feel like it could be better if there wasn't drain somewhere from android system
I plan to root today and see if I can narrow it down as well

There's suppose to be a system update that will pushed to our phones that has the battery fix. T-Mobile guys already have it...no clue when we will see it

Yea I'm waiting on that update and keep checking. There's nothing wrong with the battery life I just feel I should be getting more. Seeing people get 5hrs of on screen time and I'm only getting 2-3hrs and when I get home I have like half my battery life doesn't seem right. I feel like my battery should be giving me more than that if I'm barely using my phone while at work.

Very huge possibility as my receptions suck in here and I use wifi connection (also WiFi calling profile update message notification is constantly popup up even if profile is updated). Other thing is also I heard sprint should release software update for battery fix on note 4. Last things is battery should hit several cycles before it hits it's maximum and I just got mine last night.

Has anyone seen anything from sprint on whether they're going to push out the battery life hotfix anytime soon?

Sprint Forums are very active with people complaining about battery life and battery heating up issues.
Although sprint doesn't seem to want to acknowledge that samsung has released fixes for the battery.
https://community.sprint.com/baw/message/873447#873447
Here's the link to all the complaints:
https://community.sprint.com/baw/thread/175655?start=0&tstart=0

This is apparently the firmware version that the fixes are in:
Note 4 Firmware Update XXU1ANJ4

Talked to samsung they claim there are no firmware updates for the Sprint Note 4 and no plans to provide any for anything relating to battery drain.

After playing around turning lots of things off I can now get through one day with very light use. The two biggest helps for me were turning off the connection optimizer and turning off the wifi. The primary reason I think the battery is draining is that while the wifi is on if your not connected to any wifi networks it scans for networks every 10 seconds. Even if you are connected to wifi it scans for networks every 10 seconds. I don't know if this is the primary reason my battery is draining but like I stated in previous posts I'm stock, I've got very few apps installed. I was barely able to make it through a day with this monster 3220 mA battery. Pretty disappointing for the cost of the phone. Both sprint and samsung are completely useless to talk to. They suggest all the same sh?t that I've been doing for years to improve battery life. I will they'd release the firmware that was released for t-mobile and a number of the international versions. It's been done on like 6 versions that I could tell last I looked.

While it's far from guaranteeing an update, it is disingenuous by Samsung to claim that they have "no plans to provide" as the NJ4 rdf is up on the Sprint website (albeit unpopulated). NIE and NJ4 are the only two RDFs I've been able to find, which indicates Sprint at least has been provided the NJ4 patch. Only time will tell if Sprint actually decides to push it to our devices.

I'm not bragging but I'm getting excellent battery life. Couldn't be happier with it. I'm not rooted, yet. Most days I'm getting 8-9 hours of screen on with what I consider to be moderate to heavy usage and 18-22 hours between charges so it is possible and I'm not turning everything off to get it. I'm using my phone the way I want to.
I text and use WhatsApp. Lots of XDA and YouTube. I play some games, though usually not ones that really tax the phone. Constantly looking at Business Calendar Pro. Using the finger scanner to unlock the phone frequently. Using the pedometer, the SpO2 sensor sometimes. Connections Optimizer is on. I leave WiFi on all the time whether I'm connected or not because I use it to trigger my Tasker profiles though I am connected to WiFi almost all the time most days. Brightness is turned almost all the way down when I'm home which is most of the time and when I'm out I have auto-brightness on. No Bluetooth. No NFC. Mobile data off when I'm home on WiFi. I use Greenify to hibernate apps like Facebook but since I'm not yet rooted it doesn't do it automatically. I hit the hibernation widget when I think of it which is only occasionally.
Anyway I'm not sure why I get such great battery life and others are having so much trouble. One thing I probably do differently than most people is something I learned to do on my S3. I noticed when I first got it that if I unplugged it soon after it hit 100% charged the charge would drop somewhat quickly. I've been using Battery Monitor Widget for years so I started paying more attention to it and found that even after the phone said it was 100% charged and I should unplug it, it was still charging at a decent rate. I started leaving it plugged in until it dropped to receiving 1-2 mA. After doing that I noticed a significant improvement in battery life. I got a ZeroLemon extended battery for the S3 and continued charging it the same way. This worked especially well with the ZeroLemon and I actually found it to be extremely necessary because if I didn't let it charge that extra time the battery would lose 15% in about 10-15 minutes, screen on or off!
I tested unplugging the Note 4 soon after it hit 100% when I first got it and the charge dropped somewhat quickly. Switched to my old go to method of letting it charge until it says it's only getting 2mA and I started regularly getting 7.5-9 hours of screen on. I don't believe this to be a placebo effect because it worked on the S3 with the stock battery and the ZeroLemon and now the Note 4 stock battery. It works for me! Anyone having problems with battery life might want to try it. For my Note 4, this usually means charging it for about 1 hour and 40 minutes after it hits 100%. I realize a lot of people may not have the time to do that.
Oh and I also noticed that if the phone is left plugged in for hours after it hits 100%, such as charging overnight or even just charging for a few hours after hitting 100%, the charge drops fairly quickly so there seems to be a sweet spot, IMO. I charge it just about an hour and 40 minutes after it hits 100% and it does great.
Apologies for the ridiculous length of this post. LOL Hope it helps someone!

Does leaving mobile data off when in Wi-Fi really make a difference? I would think that since you're connected to a Wi-Fi network you're only using that and battery should reflect that accordingly.

If you're referring to what I said in my post about turning mobile data off when I'm home on WiFi, I honestly don't know if it makes a difference. I live in a bad spot where my phone jumps between 2 towers constantly and there is LTE but I'm on the very edge of it so in the house, off WiFi, it goes between a lousy 3G connection on two different towers and then occasionally connects to LTE for a few seconds then back to 3G. I just thought it would be better to turn it off since I'm not using it. I'll test it on my next battery cycle or two and see if there's any difference because I really don't know. I was also thinking that with the connections optimizer it might be helpful to have data turned off. I've always done that. I'll test it though because it's a good question.

I was.
I did leave my mobile data off overnight and was getting notifications from textra that it couldn't download an MMS and it took me a few mins before I remembered that I had toggled mobile data off. I thought MMS could download over just WiFi? If not this doesn't seem like a viable option for me during non sleeping hours.
