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.

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.

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 were on wifi the entire day.
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.

Most of the time I was on wifi, but not all.
But fair enough, I will test on 100% without WiFi. However, we don't have HSDPA+ unfortunately. Only HSDPA or 3G.

sounds dumb, but are you sure you have Verizon's GNexus? Your profile shows an AT&T carrier... otherwise you should probably update it.

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.

I've got to break the well spoken rule about battery life threads.

After long being one of those people who would never post a thread with bias questions or answers.
It's come to this.
I long for the battery I had from ICS, I never got less than 4 hours screen on and 16 hours standby together.
The best I got was right at 5 hours screen on with 18 hours standby.
All with wifi/3G only, very little to none 4G, it's fine with me.
AOKP M6.
_____
Every single ROM/Kernel combination since I've moved to JB has provided me with just......crap......
AOKP, AOKP kangs, CM, Liquid, CNA, and Eclipse along in different combinations with
Faux, Lean, stock, 007, TinyKernel, and Trinity kernels.
It does not matter what combination I use.
I can barely get over 3 hours-ish screen on time with about 12-18 hours standby.
Now if I use the screen less than 2 hours, I can get up to two days standby, which is nice but not the overall complete usefulness I had.
I know battery has long been an issue for many of us, but I see people in threads talking about their 2 hours of screen on time like it's amazing when it's awful, especially when some of us, could, and used to get close to 5 with stock batteries or 2100 extended (mine)
If you're using LTE all the time, only 2 hours screen on is justified because it should be common knowledge what happens.
Point of the thread is this, I want to know, those on JB with stock or 2100mAh battery and can manage 4+ hours screen on and still close to a day of screen on, what's your secret? Every detail, spill them.
Is it our fault or are we just in a down time of battery efficiency in the ROMs and kernels?

There is no secret, jb is crap when compared to battery usage on ics

Couldn't figure out why my battery life was so poor the for the last month or so. Good to see I'm not the only one with the problem.
AOKP ICS with Franco kernel gave me amazing battery life. Jelly Bean not so much.

I personally believe that anyone getting more screen time than you (this goes for anyone) is:
a) Using their phone in an environment that is less bright than you (indoors, on the bus, in the subway)
b) and / or not syncing as many things as you / not as often as you.
Reverse the above for people getting less screen time than you.
This is the truth of the matter.
Personally, I get 2 to 3 hours to 3.5 hours of screen time on JB, depending on usage.
4 hours if I read in bed at night.
Edit: Kernel / ROM be damned, maybe it'll make 10 to 15 minutes worth of difference. NOBODY has presented scientific proof of any ROM/kernel being different from any other. It's always "oh yaa best battery life ever with this rom". It's just noise and cherry-picked screenshots.

I usually get at least 1 day worth of charge. My set up is pretty easy tho. Since I am in front of a computer 75% of the time , gmail sync is turned off, twitter is @ 4 hours, Facebook set to never with location turned off. Phone gps and location are also turned off unless I M walking towards the bus stop. I don't need to be checking my phone every 5 minutes so my useage is pretty stable and predictable. I wonder what you guys are doing to make the battery die so quick? If your usage patterns are pretty high with checking email 100s of texts and lots of twitter and Facebook well yeah I'll die quick.
Also I seem to get the same results with custom kernels and stock. I have little experience with CPU controls and and such so maybe setting a lower frequency will help?

Battery can be related to many causes leading to user error. I never used ICS on this phone so I honestly have no idea how great the battery was.
Google now, project butter and many other optimizations are to blame yes.
Depends how much you use it and what is going and the vary of networks going on and off and switching. I can normally pull off 3-4 hours of near heavy use. My droid incredible could only get at least 1 hour max. So maybe it is me but the nexus is a godsend for me.
Leaving the governor at interactive with low max and undervolting will help battery and a specific kernel. I can normally roll with 0-10% brightness and have all networks running and syncing.
I'm tired and ready to cook my tacos I'll be back later with more input.

STOP overclocking your phone (even to 1350), under clocking exists you know.
STOP using interactive governors.
STOP using your phone so much.

Try this...
I have an old Android phone that my boy plays with...so I turn the cell radio off & have it on the wifi signal only. Even with him having the screen on for hours & hours (usually playing games), the phone will stay on battery for almost 4 days!
Turn your cell radio to airplane mode & then turn on wifi only...mess around with it, play games & see what the difference is. When I have a Sprint signal (usually junk 2g one) at home I get poor battery life...when I hack the PRL to choose a 3g (better) signal I get twice the battery life...
I've seen other battery life threads where the signal is a MAJOR factor & even with a strong 2g signal the 3g is probably better at not wasting battery. (4g is a whole other story)

I've found 4 things that almost double my battery life
1) Google Maps: huge battery drainer. freezing it doesn't help either, it has to be uninstalled. Mapquest from the play store is a decent battery friendly alternative. or if you really need gmaps, copy the .apk file and install it when needed, then uninstall afterward.
2) Push Email apps: i.e. Yahoo mail app, Gmail app... use the built-in email app and set the refresh limit to every hour.
3) 3G/2G: when your not using data, put it to 2g networks only. huge battery savings especially if you're somewhere with a weak 3/4g signal.
4) NFC/WIFI/GPS : turn them off if your not using them (obviously)
your results may vary, but doing these things did wonders for my battery. I average 23-26 hours with 2.5-3.5 hrs screen on time. before that I was getting 14-16 hrs with about 1.5-2 hrs screen on

Well, Switching 2g/3g is pretty battery draining, too. So better be sure you don't use 3g networks for a while. constantly switching just to be a minute or two at 2g just drains more
Turning of WiFi is pretty obvious but NFC and GPS shouldn't take any battery juice if they arn't in use... Someone tested it and could proove, that gps only uses battery power if it's searching for a connection.

As you can see, you basically need t neuter your device and constantly worry in order to get 'great' battery life, lol.

Its a small battery, they should up the battery sizes. They can fit the samsung galaxy note 2's battery in the samsung galaxy nexus if they wanted too.. /the end.

yea I only switch to 2g when I know its just gonna be sitting in my pocket for a while, like when I'm at work. in that situation it definaetly helps. but your right switching constantly is bad too. :thumbup: as for NFC and GPS, it just seems to help for me, maybe its just placebo. like I said results may vary

[Q] Battery life?

This is my typical battery life I'm getting is this normal with stock jb Rom? Which of the sense roms have the best battery life? I know best way to find out is to try the different roms but I'm a college student and I really don't have time to check each out. Thanks in advance!

Battery life depends on how u use it and diferent roms have different mods, so the rom best for me may npt be best for u. I have found ordroid rom to give decent enough battery.

yeah I understand that. My question was that is battery life supposed to be like this on the OneX ? Idk what kind of battery life its supposed to be getting. The previous phone i came from was lg g2x which with jellybean custom rom ran out every 3 hrs I always had to take my spares with me to make it through the day. I don't do any heavy gaming on my hox just lite puzzle games. I listen to music, sometimes read an ebook, messaging, check emails, and occationally browsing to look something up.
Is undervolting/throttling the t3 possible?

u have the wifi on at all times
no wonder u are having battery issues
try to turn off wifi when not in use
without wifi and data on, I get 1-2% drop in battery overnight (more than 8 hours)
and on a daily basis, I get 1 and half days of battery - normal browsing, gaming, calling
that is after 2nd jellybean update - which aims to improve battery life and remove a few bugs

Try out ncx kernel by neocortex.. it did quite well for my battery life. Also install betterbatterystats app. Sometimes some rowdy app may not allow phone to go to deepsleep. It causes partial wakeblock . The app will allow to check if this is happening. If it is remove that app causing wakeblock

My HOX was a battery life tome on apx. two days (occasionally 2½ days) and I use it like this:
I go to school every weekday for 4-5 hours, which means that the phone is not used that much in this time. Occasional Whatsapp messages and texts and maybe a phonecall lasting a few minues. The wifi is off during this period of time.
After school, I use Facebook, Maps, Google Now, checks mails, chats on Whatsapp and texts on a regular basis. Maybe a few phone calls as well. In the late afternoon / early evening I get home - and Tasker turns on my wifi which lasts until next morning when I leave the house (Tasker automatically turns the wifi off) during the night Titanium Backs up the phone.
I only get apx. one day of battery life, if I start playing all those games you can get... So I more than often don't play games on my phone.

for me its Renovate awesome rom awesome battery awesome theming

Thanks for all the replys guys... I just experienced some wierd stuff again. I charged it over night and its saying its only 66 % charged... Looking at history it apparentlycharged and started drilaining like this: is this supposed to happen? This was on charge the whole time and it was pretty warm when I picked it up off my bed

How much screen time do you have with the picture you posted in the first post?
I have my wi fi on all the time too but I can easily get 20-24 hrs of battery with 3-3.5 hrs of screen time on stock.

Umm I meant how long was your screen lit up. If you have Jelly Bean you need an app like GSAM to check that

its known issue with HOXS battery life sucks on stock rom get custom rom I would rather ARHD great battery life and also greater performance than stock

[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.
