Galaxy Nexus Myths

In an effort to soften all the bad feedback this phone has received, I have compiled a small list of the major complaints that have been mentioned regarding this device and will attempt to defuse them with fact and suggestions. Hopefully this will deter someone from posting the 100th "The Galaxy Nexus screen sucks!" topic.
This post isn't to claim that there isn't anything wrong with the phone, just to have a peek at how a normal device should function. Sort of to give people a benchmark to compare theirs to. More updates to come. Without further ado:
The Galaxy Nexus battery sucks!
There are a couple reasons why you might be experiencing less than favorable battery life. The first is what I like to call New Phone Syndrome. This has several side effects. The first being that your phone is so shiny and new that you can't seem to take it out of your hands. The Galaxy Nexus has a beautiful 4.65 inch Super AMOLED screen that, unfortunately, uses a lot of power. This combined with a fresh battery that isn't calibrated will give you poor battery life. After the initial newness of the phone wears off and you go through a few battery cycles, you should notice an increase in battery life. Depending on your usage, you could get up to a day or more of use. This will vary greatly!
A more legitimate concern pertaining to battery is a poor reception area. When you phone is in a poor reception area, the OS will attempt to alleviate this by routing more power to the radios. This gives the radio a little more juice to try to find a signal and hold on to it. This unfortunately causes a huge battery drain even when you aren't using the device. This will show up as "Android OS" under the Battery menu in settings. Connecting your device to Wi-Fi will not help much either since you still need to be connected to make and receive phone calls. Your only recourse is to stay plugged in while a low reception area or switch to airplane mode. Maybe a future update will lower the power routed, but I would prefer to have a signal than no signal at all.
Under normal circumstances, your phone should drain virtually no battery at all while not in use.

The Galaxy Nexus has horrible reception!
Research has been done to show that the Galaxy Nexus gets service at equal or better levels than current phones. There are a couple explanations as to why you might think you are getting worse reception or might actually be getting worse reception.
Signal Bars
The Galaxy Nexus calculates the signal strength and converts that into bars differently than other devices, specifically Verizon devices. What this means is that the Galaxy Nexus gives an ACCURATE bar indictator for signal while previous devices give some magical trickery that usually leads to full or nearly full bars. In actuality, they are using the strength from a different network type, typically EVDO, which is inaccurate as to what your true signal strength is.
AnandTech did an excellent write-up that sheds more light on the situation.
Defective Device
I know it's a tough pill to swallow that your brand new $200 - $700 device may be defective, but it might be true. If you are constantly getting dropped calls and data issues where in the past you had not, there could be an issue with your device. You first stop should be to phone up, if you can get enough of a signal lol, your service provider. Explain the situation to them and see what they can do for you. You may have to get your device exchanged a few times but don't give up! Your device should be free of any reception issues and this is NOT an issue for every device!
Exhibit B and C:
The Galaxy Nexus has a horrible screen!
The short answer is no, it doesn't. The long answer is that the Galaxy Nexus has a beautiful 4.65 inch HD Super AMOLED display. Many will complain that it has pentile-based display but honestly, this is hardly noticeable unless you are using it at an extremely low brightness setting. If you are having display issues including weird lines, etc, your device may again be defective and you should try to exchange it not post a "The display sucks!" topic. It won't help much.

The GPS Sucks!
After the Galaxy S GPS debacle, many people are rightfully concerned that the GPS in the Galaxy Nexus would be subpar. Fear not! I can safely say that the GPS is rock solid. This could vary based on carrier and location, but generally you should see similiar results. If your GPS is taking ages to lock or you aren't getting a lock at all, again this could be a hardware or even a software issue. Troubleshooting is your best bet, probably a replacement device.

if you load a low-resolution picture on a HD, of course it suck. thats why i switched all my WP to HD *must be over 1200 res.*.
as for signal, perfectly fine on my GN, and battery life.... still cant beat my friend's 4s. same game but my battery die faster....

Yup, probably my things syncing in the background but the battery only drained 4%. Total awake time was an hour out of the six hours. 28 minutes of that I was actually using it.

Oh yes! I was going to mention that. Mind if I take your quote? Give you credit of course.

what's this about looking in the mirror and saying "galaxy nexus!" 3 times?

Good write up. Now what about the low volume issue? Is it widespread? GPS issue as well?

i wouldnt call the volume being low a myth...it is rather low, but then i'm coming from a phone that has stereo speakers on the side of the phone rather than the back...where it sits therefore muffling the sound more from a low starting point :|

Exhibit A is not a good example cause you were on Wifi the whole time. A lot of people throughout the workday will not have access to wifi and wifi is known to have less battery drain on standby.

I wonder if the low volume is hardware related at all. With past phones(that had Sense stock of course), anytime i'd try out an AOSP based ROM the volume was always noticeably quieter then on Sense. Devs would always attempt fixes but no matter what it wasnt the same. It makes me wonder how the volume would be on this phone if it had Sense.

I've gotten nearly the same drainage on mobile date which is why I mentioned the fact of being in a bad reception area will kill your battery. I can do another test on mobile data and post another shot.
I will do a screenshot of the GPS and post that, as I get rock solid GPS.
My phone is normally on vibrate (I don't like my phone making noises) so I really can't speak to that. When I do have the volume turn up, I haven't had any issues with it.

Updated with GPS. Anyone is welcome to add other topics and I can add them.

Your list is pretty spot on, but don't underestimate the "signal" problem (although I won't call it that henceforth). While I don't think there is a signal reporting problem, as you pointed out, there does seem to be lower performance out of this phone compared to some of the competition, specifically in areas of weaker signal in terms of maintaining a data connection and handing off between 3G/4G. That has been my experience.
Your assertions are in line with reported information from AnandTech, and I agree that some people's problem is a perceived problem due to "Signal Bar goggles" or ignorance to signal reading reporting between phones. But there are still legitimate concerns about data handoff between EV-DO/LTE as well as this phone's ability to hold signal in weaker areas. Those are real issues for real people. There are plenty of examples, myself in included, who see their Nexus fail to keep LTE where other phones do not, and fail to keep 3G where other phones do not. When I'm in a good signal area, my phone performs simlarly to HTC Rezound, Charge, Razr, Thunderbolt, and my old OG Droid. But put it in a fringe area, and the performance differences become more clear in both ability to hold the LTE or even 3G signal as well as data rates.
Maybe there's nothing "wrong" with the phone, it's just not as "good" at these things as some other phones (and that's certainly allowed), but just don't write it off yet as nothing wrong with it.
I've also seen my GPS on a few occasions have me somewhere miles away (even up to tens of miles away) from my actual location. When it's locating me 60 miles north of where I actually am, even with WiFi on, I'm calling shenanigans. I've had the phone for a 9 days and it's happened 3 times so far. Just something I'm keeping an eye on.
I'm not in the camp of people losing data completely for extended periods of time, and for those people, I would suggest a phone exchange. I think my device is behaving as designed, and there is just possibly some questionable performance issues compared to some other phones. For that reason, I'm keeping mine and being hopeful of updates addressing these concerns.

Uh the whole reception issue is a reality. It has nothing to do with reception bars etc. I have losr data connection numerous times and a few dropped calls in the los angeles and orange county area. And its ****ing frustrating.
The camera is meh. In many occasiosions its doesnt focus properly, so you get fuzzy pictures. Though the ipone4/4s and galaxy s2 devices are obviously better.
The gpu so far sucks. Its been underclocked, and ppl see lag in their live wallpapers, and especially in emu's like n64 and psx. Hopefully a good overclock will help this issue.
The battery is very lame, but i think that was a given because of 4g, i get some extra life by turning that off.

I never said the reception issue isn't real. The myth is that all devices suffer from this problem. My suggestion was that if you are having a bunch of problems that there might be a problem with your device.
Camera, I refer to the OP.
GPU, could be an issue with the high resolution and large screen. Probably will be optimized in the future. I'm running 4.0.3 and it's very smooth.

I see. So the title " The Galaxy Nexus has horrible reception!" Is not a myth and is partially true

[Q] Looking to buy a Nexus (Verizon 4G LTE, Hook Me!)

Hello everyone.
I might be trading in my Razr Maxx for the Nexus soon. I have 4 questions.
1. I come from a thunderbolt. That battery is horrid, do you understand me? HORRID. The Razr Maxx is a really nice improvement but I don't need all the juice which opened to me the oppurtunity to get the Nexus. How is the battery on it? I mainly make a few calls, text a lot, check email, and browse the web, watch the occasional 2-3 minute video. Will ROMs fix this?
2. I hear stuff about the signal being bad? It drops a lot? Then again I hear about this leak and it may fix it? What are you Nexus users thoughts on that?
3. How can you describe the overall phone?
4. Lastly, here's where you guys can go crazy, why should I get it over the Razr Maxx?

Why should you get a nexus? Read the dozens of threads in this section asking the same question, there's a new one almost daily. You're asking Galaxy Nexus owners about this device versus a locked down Razr Maxx, take a guess what they're going to say.
All the questions you asked can be answered by reading the threads, some are on the first page.

I'm bored, I'll bite.
1. I get about 3 hours of screen-on time with 3G, maybe an hour more if I'm on wifi. It will standby forever. Custom ROMs/kernels help a little with battery life, but not enough to really change your overall perception of the phone's longevity. I have the stock 1850mAH battery.
2. I generally doesn't display a signal as high as other Verizon phones, but some chock that up to other phones displaying the signal inaccurately. There are a very small amount of people who have legitimately low signal with their Nexus (which can be verified in dBm), and it's usually accepted that these units are defective. That said, I've had mine since 12/15/11, and I haven't dropped a single call or been without data.
3. It's got a nice form-factor (if you don't mind the plastic construction), the screen is great, and ICS rocks. I really like it.
4. RAZR MAXX has it on battery, that's about it. Ice Cream Sandwich is lightyears ahead of Gingerbread, especially with Moto not-blur and a locked bootloader. I wouldn't even consider owning a Gingerbread phone after having a Galaxy Nexus. The form factor is important; the software absolutely makes or breaks a device.

guess your right, I'll look around.
edit: Stad, read your post thanks. So it's not as bad as a thunderbolt (idk if you've owned one, it's like 7 hours w/ 4g minor minor usage). And it's not the best battery right? That's my deciding point right there.

Their is only 2 phones to buy.
A Nexus or an iphone.
Everything else is crap. Full of bloat and skins. Never see updates.

Lol, true.
I know there's always a bricking chance when screwing with root/bootloader shenanigans, but how safe is it on the Nexus?

Honestly I keep 4G off all the time unless I need the speed. I don't know about you, but I've found Verizon's 3G to have acceptable speeds for 99% of the situations I'm using it. The ROM I'm using (AOKP Milestone 3) has nice toggles in the pull-down notification bar, so it's really easy to turn LTE on and off if I need it.
I've heard of people getting better battery life. There's a guy over at Rootz who got 4h50m screen-on with AOKP and imoseyon's leanKernel on a standard battery, but I haven't been able to get anywhere close to that.
In real-world usage, the battery life is plenty. Yesterday I woke up at 4am and wasn't in bed until 11:30pm that night, and my phone still had 38% battery left when I crawled into bed. I forgot to plug it in when I fell asleep, and woke up to see it at 36% about 5 hours later. But, if it's not clear by now, not much of that was screen-on.

Unless you pull your battery while flashing a bootloader (which you might do once or twice during the life of the phone, if at all), you'd have to be trying pretty hard to actually BRICK your Nexus. The bootloader is unlocked with a single line in fastboot mode, and ROM flashes-gone-bad can always be recovered as long as the bootloader is borked. This phone is ridiculously easy to modify.

That's great thanks for all the info.
Did the rootz guy run on 4g or was that 3g, I'll find out myself if u link the post.
Now to stare at the two phones for 8 hours and see what I choose, lol.

no keyboard prediction on browser
no fixed landscape mode
no permanent desktop mode
3 hrs of web surfing
battery life on gaming? good luck
lag once in a while
photo from stock camera are little bit washout
no facebook sync
Once the signal got dropped, it takes a while to reconnect.
all in all, i need to charge 2 or 3 times per day on average use (my average use). if i dont see improvement on 4.0.4 or future update, i am moving to iphone 5. i have been using android over 2 yrs now and still havent find any advantage over iphone.

I'm on Eagles Blood ROM, using Franco kernel. Stock clock with ondemand governor. All I did was undervolt 50mA across all frequencies. I was on wifi for most of the day since I was at home, but my typical work day doesn't put the battery under 50%.
The battery on this is way better than the one on my Amaze was, so that's all I really care about.

"Cell standby" suddenly draining the battery

I only noticed this problem after using BeastMOD for a couple weeks. One day, my battery was almost dead by the time I left work in the evening, and this is not normal at all. I noticed that in the battery history, Cell standby was the main culprit, taking up around 30-40%. I have never seen Cell standby taking up so much power until now.
After having some issue with BeastMOD, I installed Juggernaut about a week ago. It was fine at first, but now I'm seeing the same problem with Juggs too! Does anyone know why this suddenly starts happening, and if there is a permanent solution?
I tried to take a screenshot with Juggs, but something isn't working. Time without a signal is 0%, but this reading often doesn't even show up.

This can occur if you are in a place of low signal coverage for a while. The lower the signal quality, the harder the radios try to maintain a signal.

It could be because of the applications running in the background that takes up the battery while the phone is idle.

Correct. Specially if your radio is constantly switching from WCDMA to GSM due to poor reception. Generally if you're on GSM and you don't have great signal then you wont see a dramatic effect on the battery but its the complete opposite when on WCDMA.

Yeah, that's how I understand it. What doesn't make sense is that this would happen suddenly, and then not let up. The phone would be running fine for a week or two, then suddenly the cell standby shoots up. I'm not visiting new areas that I don't normally go to. This is only at home and at work - two places I spend the most time at. And both of these areas have good coverage from T-mobile.
When it shows it, Cell standby will show 0% for "time without a signal".
I disabled Juice Defender, and I'll see if that makes a difference in the next couple days. So far, it doesn't look like it. Cell standby is at 29% right now - much higher than normal.

Do you use your phone at all during work and home? I leave my phone on standby in school and it is normal for me because I do nothing else at school with my phone. When I get home and start using my phone, Cell Standby disappears. And the percentage next to the process is the percentage of how much of the battery lost it is responsible for. If your battery is at 80%, and Cell Standby says 40%, it is responsible for 40% of the 20% drop in battery, though I'm sure you know that already. I have never seen a case like yours, though. From what I can figure from the screenie, Cell Standby is a huge problem because it is at 10% battery from 100% in 10 hours and 39 minutes and that is really short for standby only. The apps that I see that take up battery are the same system apps on my phone when on standby. Try replacing your battery, and if the problem consists, then I suggest you UNROOT it and exchange it. If they charge you, argue because after all, it isn't your fault. Your drainage is extreme though, because at 10 hours on standby, my phone would have at least 60% battery left.

If your battery is at 80%, and Cell Standby says 40%, it is responsible for 40% of the 20% drop in battery, though I'm sure you know that already. I have never seen a case like yours, though. From what I can figure from the screenie, Cell Standby is a huge problem because it is at 10% battery from 100% in 10 hours and 39 minutes and that is really short for standby only. The apps that I see that take up battery are the same system apps on my phone when on standby. Try replacing your battery, and if the problem consists, then I suggest you UNROOT it and exchange it. If they charge you, argue because after all, it isn't your fault. Your drainage is extreme though, because at 10 hours on standby, my phone would have at least 60% battery left.

I use the phone at work, though typically pretty lightly. I don't see how this could be a problem with the battery. The battery isn't telling the phone to do anything, just supplying it with juice. It's very inconsistent, though now I've experienced the problem with two different ROMs.
I've plenty of references to the flight mode "trick", where you turn on flight mode for a few minutes, then turn it back off. I don't know what this is supposed to do to the system. I had tried this before with no luck, so this morning I put the phone in flight mode for half an hour. Currently cell standby is only at 12-13%... we'll see if the problem comes back.
I bought the phone from wirefly, and it was back in October. I don't know if I can exchange it anymore... RMA with Samsung, maybe...

Yeah. Samsung is your best bet since you didn't buy it directly from TMO. I also had the same problem except that the culprit was IMS Service. I uninstalled that, but I'm not sure about your case. IMS wasn't essential. Cell Standby is and I don't think you can even uninstall it.

Are you on an actual ICS ROM? That might be the problem, since we don't have our own KERNEL for it. Try flashing Bombaridier if you are on ICS. GB might fix the problem. Or flash EasyDoesIt which is also an ICS ROM, though I haven't let the battery settle for a couple of days. For the most part, it was normal for me.

I know this is a pain-in-the-ass suggestion, but you might want to try reflash back to stock 2.3.5, do the OTA upgrade to 2.3.6 (which should reflash your modem), and then see if the problem persists. This would completely rule out any kind of software/firmware issue.
I still think it's likely a signal quality issue, though. Not all signals are equal. Just because your phone a strong signal doesn't necessarily mean it has a strong 3G/4G signal. The signal icon can be very misleading and will often display the "4G" signal even when it really is only connected to 3G bands. The radios will constantly try to "step" up to the next band by testing the signal. This process consumes excess battery power. Have you tried setting your phone into 2G only mode and determining whether the problem still occurs? I'd also go ahead and turn off Bluetooth, WiFi, and GPS radios while you are at it.

I just might have to try going back to 2.3.5. I did flash the 2.3.6 stock ROM and was using that for a long time before trying out Beast and Juggernaut, though. Does that not flash the modem?
The reason why I flashed 2.3.6 instead of doing the OTA update was that after I un-rooted and went back to stock 2.3.5, I didn't get the OTA update message and Kies wouldn't update me either.
How do I selectively turn off 3/4G? I only see the "Use packet data" option.

As I understand it, flashing a 2.3.6 ROM does not update the modem. It's the same reason a nandroid backup won't backup/restore your modem. You should be able to find out pretty quick by going to Settings > About > Baseband version. It should be T989UVKL1 for the stock 2.3.6 Hercules modem.

My baseband version is T989UVKL1, so apparently I'm using the 2.3.6 modem.
The problem isn't happening today. Cell standby is at 10% at the moment. I turned off packet data this morning for a few hours, and turned it back on around noon. If the issue comes up again I'll try switching to GSM only and see if that does anything.

The problem came back a couple days ago while I was at work. Around noon, I noticed that Cell standby was taking up over 30% of my battery life, and the battery was draining much faster than normal. I turned off Wifi and left it like that for the rest of the day. I checked the battery usage periodically, and the Cell standby percentage steadily dropped till it was in the low 20's. That was a couple days ago, and I've left Wifi off since then.
Today, Cell standby is at 11% and the battery usage seems relatively normal. I'm at 63% after almost 6 hours.
This makes very little sense to me, but I'm putting it out there anyway. I know there's a problem with one of the wireless routers at work when PCs connect to it, so maybe my phone is having issues with it too. Still, though, I don't know why that would affect the cell radio. There are several different wireless access points at my work, so I'll try those out too.

Do you have wifi calling enabled? If your wireless router has signal problems, this could cause the same effect as cellular signal problems... it could be constantly switching from wireless calling to network calling and never letting the cellular radios enter their sleep states.

Let's not spread false info, our device is not 4G at all. LTE is 4G period.
To the |OP|, 1st off get rid of that juice defender crap. I have ran both ROMS you have named in an area that gets horrible service coverage. I have no problems with cell stand by even with wifi, GPS, data, & sync enabled. I was still pulling about 23-24 hours with moderate use. Enable wifi calling to curb the modem changes when you are in wifi range. Wipe cache, davlik and battery stats. If that persists try the new blaze radio in the dev section. I wouldn't recommend going to stock and OTA to anything. All the stock roms have a bunch of bloat that eat battery and data. Report back your findings and we will see how to help you further if this doesn't fix the issue.

I don't have wifi calling enabled. I tried it a few times when I first upgraded to 2.3.6, but it didn't work very well for me. The sound was scratchy and noisy, so I disabled it and never looked back.
For the last couple days I shut off wifi completely, both at home and at work, and this has improved the battery life. Yesterday, after about 14 hours, I was still around 40-something % (I wanted to take a screenshot, but screenshots aren't working with Juggernaut on my phone). I have been using the phone pretty lightly the past couple days. Cell standby was in the low 20% range.
I will try another wifi hotspot at work to see if that helps. Just curious, what do you have your Wi-Fi sleep policy set to?
Edit: I have had Juice Defender disabled for a while now. It didn't seem to be the source of the problem.

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.

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.

[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.
