[Q] Several Questions About This Phone...To Keep, Exchange, or Return...Please Help

Greetings,
I bought the GNex from Expansys USA the day it came out and I have had the phone for about 5 days now. There are several things that are making me questions whether or not to keep it, get an exchange, or return altogether. Please advise:
1. The main thing I am concerned with is the battery performance. I am a Noob, so I am not sure how to run all those fancy battery tests, but I can say that when I take the phone off the charger in the morning there is only about 30-40% left by the afternoon, and that is with moderate browsing, music, and a few calls and texts. I installed the Advanced Task Killer to try and save battery life. I am coming from an iPhone 4 (I was locked into it with a contract, bad purchase I know) and it seems that the battery life is way better on the iPhone. Is there a way to determine if my GNex battery or device has a genuine problem before I return this one and potentially get a worse one? Also, I read somewhere that with these batteries they get better over time, is that true?
2. Since I got a GNex from the very first batch sent to the USA, I am wondering if the newly resumed/shipped batches will have the volume fix installed? If so, is it worth me sending back the one I have now for a newly flashed one with the update? How can anyone tell if their device is updated anyway? I have Android Version 4.0.1, but isn't that what everyone has now?
3. The speaker volume is not that impressive, and I tried installing those volume booster apps to no avail. Is the speaker just not that powerful on this device?
Feel free to insult and/or flame me on my previous iPhone usage and also my lack of technical knowledge. I love the GNex because of it's amazing features on paper and all the available bandwidths I can choose from as I travel abroad frequently and this is one of the only penta-band phones I could find other than a few Nokias. But they don't run Andriod!

Android has "worse" battery life than iOS mostly because it has true multi-tasking and constant connectivity (unless in airplane mode). They generally do improve slightly, but anything 8 - 12 hrs. is pretty average, with "average" usage.

You will get an OTA (over-the-air update) sometime over the next 6 days. Most likely any replacement one you received you would still have to wait for the OTA anyways.

No, it is fairly underwhelming (Nexii always have been actually)

Thank for the quick reply s.m.knipe! Like I said I am new to this type of phone OS, so I appreciate the answers. I forgot to add another question before:
When I make a call, and I tap the icon for speaker phone, and then immediately try and tap the icon for the keypad numbers, there is a delay and the keypad numbers do not appear immediately. I guess I am saying there is a lag of sorts between pressing the speaker icon and the keypad icon to appear. However, this only seems to happen when the phone is taking a while to connect the call. When I tried doing the same thing in a better service area the icons switched back and forth seamlessly.
I really don't notice any defects on the phone at all in terms of build quality as opposed to others' here on this forum that have screen issues and cameras not being centered so that is why I am reluctant to send this one back for replacement if there is really no problem with the battery or speaker. Unfortunately I have no one to compare devices with as this phone is rare in the US. Anyway, I guess I'll be keeping this bad boy and use it as best I can!
Regards

Ok so I just retried making a call in this better reception area, and I still have the lag between the speaker icon and the keypad icon. Must be something else besides the reception?

1.) Battery is what it is. You might want to wait for undervolted or underclocked kernels or more battery concious roms to come out. There is one (Android Revolution HD) which the first post claims to have better battery life than the stock rom. Second, as pointed out by many members, task killers do not help the battery at all. (Cannot confirm this myself, speculation from different posts) If you wanted, you could post some screenshots about your battery life and screen time and see how it compares to other members with Galaxy Nexus'. Note: The iPhone 4 has lower battery consumption because its clocked significantly less than the Galaxy Nexus (Single core 800mhz i think) and the OS itself is heavily optimized for the phone. Plus, I would assume that the iPhone has less processes running in the background compared to the G-Nexus (could be wrong though)
2.) The volume fix is being rolled out via a software update, so it should automatically be sent to your phone whether its the first batch or the hundredth.
3.) For the speaker volume, you might try changing some settings in the equalizer? Not too sure about this, but many people have reported that the speakers are reasonable in terms of performance and if you seriously feel as though the performance of the speaker is that bad, you could try exchanging it, but I doubt any good would come out of it

Since it's a new phone try charging the battery fully and letting it discharge completely. After 3 to 5 times you should see improvement in your battery life. There is a thread on this that gives more info. Also a task killer is a bad idea and the thread covers this topic too.
I have a Nexus S and it's lasts me over 24 hours on a full charge with 3G and WIFI turned on.

The galaxy nexus also has a much larger screen than the iPhone which I think also plays a part in battery consumption

Thanks for the replies! Any link for the thread you mentioned? I tried a search and couldn't locate it...

the screen is, without a doubt, the most power hungry component in the phone.

Typically the battery display says 60% of the battery is being spent on the screen. Is this in line with other GNex users?

Oh, and has no one else noticed the lag I mentioned above in the on-screen display when pressing the speaker icon and then the keypad icon and then the long wait for the keypad coming up when making a call?

nope

Anyone know where this thread is that is mentioned above with info about the battery life and why the task killer has issues or is a bad idea?

ridiculous don't you think?

the kernel is bugged and also since its on 5.0 lollipop

What strikes me odd is that something else didn't drag it down. Then I see the stats are about apps only, which don't take into account cell standby or screen on time.
The key thing to look at is that your phone has been running for 5.5 hours there from full charge, and it only went down 7%. That means if you keep it up, you could run it for over 3 days without needing to recharge. Nothing wrong with that (in the new world order). That's what my old phone could do (sometimes 4 days), and it had a better mAh to screen size ratio than his device (2460mAh : 4" vs 3000mAh : 5.5"). I have yet to get those kinds of battery stats with this one (down to 70% by the day is done vs 80% with the other one).

Yeah. It's unthinkable that a company like Asus can't solve this problem fast enough. Maybe they didn't get the permission to put 5.1 on their phones yet

Yeah, let's see. Meanwhile we spend our battery cycles like ****

I blame Google. They should never have released the buggy mess that is 5.0. Sometimes companies have no choice what to out on the phones....I'm sure Asus had this phone in the development pipeline with 5.0 as the target well before all the bugs of 5.0 were revealed. And the way Android relies on nearly full reimage for major updates is idiotic, and also Google's fault. 5.1.1 is essentially a different OS than 5.0

the funny thing is my standby time is completely fine its when im using the phone that it drains fast I have amplify,greenify,powernap running and it still drains also did all thats possible to save as much battery as possible.
I also installed the Debloated Rom by Harfainx I know for sure that its lollipop 5.0 thats cause this problem cause every time I check the battery stats in settings Android OS is at 40-60%...... thats just ridiculous

The sooner we get 5.1.1 the better! Are you listening Asus?

They are shameless at the moment

[Q] How is battery life compared to G3? (g3 owner willing to buy g4)

So, title self explain. I have G3 and want to ask to someone who made the upgrade from G3 to G4. Is the battery about the same as G3 or is better?

i had G3 and recently i bought G4 not much difference but lets say the G4 win with alittle bit but from my opinion i didnt see abig difference

advice :Stay away from G4--- this device has too many hardware issues

Don't feed the troll :good:

i was planning to buy the G4, so i looked at some reviews. GSMArena said that the battery life on the G4 is a downgrade from the G3.
The Endurance rating worked out to 54 hours, 9 hours less than the G3. The issue was with the high standby power draw, which puts a strain on the battery even when you're not using the phone. The other disappointment was the talk time, which couldn't reach 17 hours - an 8 hour drop from the G3.
We reran the tests several times and kept getting the same results.
Anyway, the web browsing time was pretty good - nothing spectacular, but good. It also marks the only improvement since the G3 as the video playback is below average for the flagship class.

ok. where does it make a direct comparison to the G3. the video is kind of hard to follow. Unless he has both phones in the same video and do a same battery test, you can't really compare the g4 to g3 with this video. the OP just has to decide which source he deems more reliable.

yes because this is a difficult subject so keep a note when he talks of the sot's under different conditions.
Had to watch it a couple of times but i got it in the end. See the comments too.
What is your expectation of sot/runtime ? How much do you get with your curent device ? what is your current device.

There is no difference between G3 and G4 for battery life max i can get 4 and half hours for battery life and minimum only almost 3 hours SOT. Maybe if next LG device is like this battery life i need to change to another brand

Yeah my experience in two days....Touchscreen issues untill i updated to V10C which fixes the touchscreen issue but decreases battery life to the extent where u can literally notice it drop before your eyes. The power saving used to work fine before v10c now even tho i turn it on immediately it wont kick in untill battery reaches 15% ( u will know when its on because the statusbar will change its color to red)...... And yes the back buttons are loose and feel wobbly. There is a pink shade in my front camera when there is sunlight in the background....ummm what else......i am damn sure even the cheap chinese phones coming out will be better than this piece of junk. I shud never have bought it

many times its because people are interested in some other phone that came out after.

Dont expect anything crash hot from the battery performance. It is nothing like what i expected. If you want good battery life go with samsung s6 or even better the sony xperia phones. Xperia has best battery life. So G4 wont do you any good with battery life

3h sot, lots of complaining, 4h+Sot less complaining or it goes silent. Seen this a few times now. That is what surprised me. Until you realise that people find 8h run time too short but once it gets into 12-14h+ its ok. Its the standby time that is more important.

I currently have the nexus 4 and i think the most screen on-time i can get before my phone dies is 3 hours, but usually it's in the low to mid 2 hour range before i have to run to the charger. But the phone never last more than like 12 hour of usage (or a 8 hour workshift+ work traffic) as i constantly surf the web, music, and always checking my phone.
I want something like xperia z3 compact or note 4 battery life, but those phones have some things i don't really like. With the G4, i do plan on buying those high capacity battery (like mugen, hyperion, etc..) if the phone does fall below my expectation.

Mostly wifi ? or is there also same amount of data ? how strong or not that cell data signal is and for how long you are on it will take a toll with any phone.

How bright do you like your screen. if you can manage with less brightness ie 30-50% you can add an hour of sot.
for reference, 3-4h SOT on data and 4-5h sot on wifi only with 65-70 brightness. mixed use means somewhere in between, 4h sot. high brightness means low to mid 3h, less brightness 4-5h.
sot/run times you can expect 3h /9h, 4h/12h, 5h/14+h is normal with stock.
Are these figures you can live with ? xperias & note 4 will give you an extra hour sot on top. that extra hour means 2-4h longer run time.
you dont need to carry those bulky batteries unless your phone absolutely needs to be on, just swap the battery out in a couple of minutes.. Not hot swap, have to power down.
How important is bootloader unlock and roms for you ? some people are forced to stick with original and forego firmware updates to preserve bootloader unlock. this means if any improvements are made in subsequent updates they can't use them and are stuck with whatever bugs are there in the older firmware. Stuck with bugs and waiting for roms can be frustrating.
For some one used to nexus 4 being able to flash anything and everything, G4 might seem a bit boring for you, Nexus 5x ? you dont care for replaceable battery or sd card. just get the biggest onboard memory possible

Yep all wifi, don't have a data plan . wifi signal varies to maximum signal to no signal at all lol. But i do turn on airplane mode when i'm on the train for example. My brightness is set to adaptive brightnes on @ 50%ish
I'm actually avoiding the nexus line in the future lol since i really want sd card slot and removable battery (and good/excellent battery life), usb OTG (particularly usb audio out), and a device that can officially unlock bootloader like the g4 H815. and to be honest, stock android ui is sometimes boring and it never has features u see on like xperia, htc, or samsung devices. And I can just do all my flashing needs on my Nexus 4 when the habit kicks in lol. Overall, on my next phone, i just want options and upgrade/replacement possibility

Then you can expect a 4-5h sot/12-14h run time with normal use. Good enough ?
web browsing won't eat up much battery, its push notifications and constant syncs over weak signal that do it faster.

IMO the g3 was garbage...i had 2 that had emmc failures and all 3 i had overheating issues...battery sucked...only pro was there was a good bit of development...i love my g4...only device i miss over my g4 is my g2...battery life is great with minimal tweaks and greenify...my last run was 5 h 2m sot and 47.5 standby...h81110n

What is the truth about the Android OS battery drain?

First, sorry for my bad English.
Everyone using ZF2 knows about what I'm talking about here: if you look at the battery graph in the settings, Android OS is probably responsible for most of the battery usage. :silly:
At first I was horrified about that, but then I realized something was off, something that I notice everyone is ignoring: Android OS drain is too high. I mean for me it's always 5 to 8 times higher than the second that is the Screen. The reality is that I can still have 4 to 4.30 hours of screen-on time, 3% drain for 7 hours of stand-by at night. So just think about it logically, what if we can make the Android OS work "normally", which is that Screen will be on top of the list and Android OS somewhere below, then how long my screen on time will be? You know what I mean? We are getting rid of a drain that is 5 times higher than Screen on the list! Does it mean our Screen on time will now be 20 hours???
So, I came to a conclusion that this issue may be in fact an error in the data. Maybe nothing was wrong but the Zenfone 2 team messed up the calculation for the battery usage and ended up showing a ridiculous result. what do you think about this?

3% overnight ? my phone get 1% ^^

wow that's crazy, how is that possible for you do you think? :angel:
I'm using stock, disable most of the bloatwares but I'm keeping all Asus important ones such as power saver (I always set it normal however), start manager (disable all except OTTs and sms ... you know why).
Does that mean I'm partly right? If Android OS truely eats up so much battery power, how can we achieve such low drain during stand-by time? It's not logical :silly:

thanks for the link. However I don't want to root my phone, I just bought it a few weeks ago and I will keep it intact until I get Marshmallow, I used to be addicted to Rom Flashing and it nearly killed me haha. I can use the lists for reference, anyway.
Yes my phone is 551ML 4GB ram, probably that's why I have higher drain when stand-by. Because I have lots of experience with Rom modding I believe I'm not missing anything with my current settings.
Ps: your English is fine, don't worry :fingers-crossed: judging at your username I bet one penny that you're from the same country as me

how many times its been said..zenfone 2 stand by time is superb ...its when its use the drainage is fast..why fast because of incompatibility of zenfone 2 screen( cheap screen ?) and intels hardward... ...so no matter how you adjust it will never be a 2 days single charged phone. anyway ive had a nice experience with my zenfone 2 ..gave it to my brother and bought nexus 6...wanted to have 6 inch phone anyway....

i think so. bạn ở đâu ?? mình hcm kakaka

The main responsable in battery drains is usually not Android OS, but Google Play Services that screws everything

This issue has already been discussed to death all over the place in different forums. There are many reasons why the battery life is not good on ZF2 some of which are what you pointed out. The main problem is with 5.0 itself, this was and is a known problem, no amount of "tweaking" is going to fix a problem with the OS itself. This is why many people wanted the 5.1 update to no avail from Asus. Did it fix all the problems? No, it did not but it did stop a lot of the battery drain.

I agree that 5.0 is not optimized and it's not the best, but people are talking like Android OS is a crimminal, I think that Android OS is just taking a bit of battery, but definitely not 5 times higer than the screen as explained above like instead of 5% of battery it is consuming 10%, it's not good, but not a disaster either :silly:

it might be, I used to greenify Google Play Services, but on some phone it will lead to a lot of force closes. Supposed it's the cause, it also can't be 5 times higher then the screen, or else our phone won't be able to maintain >4 hours of SOT, isn't it? :silly:

No, 5.0 is and was a disaster. It had so many bugs it should have never been released

That is for sure...

Battery problems?

I know, our device has really great battery life and I don't have anything to complain about that, but a friend of mine just got himself a new phone and his values make me a bit jealous and most of all: surprised and stunned.
He got himself a Xiaomi Redmi Note 4 (SD 625 variant, MKT variant really sucks), it has the same processor, same display and not even 700 mAh more (4100 mAh) and he got with some "dev rom" (made by Xiaomi, seems to just be the beta of that ugly MIUI 9, based on Andorid 7.0) 6h of SOT, doze seems to haven't really kicked in in that time. in their forum in the SOT thread I see people getting normally about 8-10 with up to over 12 h of SOT, most of them on stock ROM without any additions. And I'm quite irritated about that huge of a difference with not that much more battery. And he seems quite convinced that it's not on the cost of performance, you should notice that quickly on such a heavily skinned ROM.
Now my question is: how in hell is that even possible? I mean our devices seem quite comparablewith just a slight bump in battery but near-stock AOSP Android against pretty much an iOS clone. Does anyone have any idea what could cause that big of a difference? And if it's software based could that be done on our device? Because my experience and from different posts our device lasts about 5-6 h normally.
I mean I'm already lucky about my 2 days of usage with up to about 2.5 days on some weekends where I have a lot of stuff to do. But I wouldn't mind a bit of extra. But my biggest problem with that is as simple as: how? I could really use some explaination right now...

I don't have issues with device.. stock 7.1.1 with dec.patch, unlocked bootloader, with latest magisk. Also installed greenify.

Then you are one of very rare cases. My experience is about half of that.
And I also meant on stock ROM, without any modifications. So I don't know which apps you greenified, but that was not the point. I use Greenify too but more for apps that aren't supposed to run constantly in background when I only use it very seldomly.

The norm for this phone is 8+ hours SOT. Sometimes I get 10 and a few have had up to 12. Unless you're gaming 8 should be easy. 5 hours means something is wrong with your phone hardware, you have a rogue battery eating app or you're gaming. I rarely charge my phone over the weekend even when I use it a lot.

Well, neither of that is the case and I rarely see people claiming more than 6h of SOT

So the answer to your question is, it's the wrong question. The question should be, why does my battery not last very long and what apps or usage causes me to have such poor battery life? Compared to the Redmi Note 4 the Z Play is exactly where it should be.
Here's a link to the SOT thread: https://forum.xda-developers.com/moto-z-play/review/screen-time-t3643959
gsmarena battery life test 100h endurance rating: https://www.gsmarena.com/battery-test.php3?idPhone=8310#show
Here's an app to help diagnose battery condition (Accubattery): https://play.google.com/store/apps/details?id=com.digibites.accubattery&hl=en
also betterbatterystats is really helpful.
I sincerely hope you get it sorted out!

Well, gsam isn't detecting any app that's off even with root so I don't think there is any. I installed that AccuBattery app, let's see what it has to say

Removed because of ****ty q&a system...

Oh, and another thing I noticed: I get very randomly reboots, and every time the battery percentage drops massively. Just had a 30% drop. And after the reboot the battery percentage seems like frozen. Now I rebooted and plugged in the cable and got 44% again... No fast charging. Do that detection seems very off
Motorola forum isn't helpful at all. Clearing cache and dalvik didn't change anything and running around for a week in secure mode (that's how random they mostly are) or even doing a factory reset without restoring apps is out of question for obvious reasons.

That's pretty weird. Did you try a factory reset and after restore your apps? There's not a lot you can do if you're not rooted, but you shouldn't need to do much anyway on stock rom.
Only other option is full RSD lite OS restore as a last resort.

I am rooted for long, that's why I use Greenify. I know it also works without but then it's a joke. As RSD lite is, it just refuses for everyone to detect anything on Windows 10.
Factory reset is out of question for the moment, it takes way too long to do it properly (with titanium and NANDroid backup first) and I won't have that much time probably for the whole of this month. Otherwise I would most likely already have went off to the next best custom ROM since Motorola just can't get their **** together and still work on 8.0 in test for 2.5 month with searching testers for another one.
I think the next thing I'll do is to try the good old battery calibration, just have to find the file storing the statistics. I know many say that won't work but that's rubbish, it worked for me already a few times

Update: no, no change. Don't know if that funky battery percentage bug on random reboots still happen since I haven't had any again yet, but they come too random and unpredictable.
And that AccuBattery just proves to be worthless. It tries to estimate the rest capacity, but then it even fails to detect original capacity by 500 mAh. The battery sucker stats are also unrealistic. It puts chrome first with 10%, while GSam with root puts it 5th at 4.6% after kernel, Spotify, Android system and fight services. Android itself even puts it 9th with screen, phone idle, cell standby, Android OS and Bluetooth in-between.
So let's see what happens first. Motorola releasing 8.0, which I will flash through the .xml.zip, this time using flashfile.xml which should force a factory reset... Or me finding the time to switch to a custom ROM
Edit: so I got another one, bit this time no crazy battery drop. But the other times I killed of the soft reboot sequence because Magisk can have some problems with that. This time I didn't

Yesterday I was finally able to do the factory reset since those darn random reboots became too annoying and Moto's support is had just the most ridiculous ideas... In the worst way.
Either way, now OTA looks better, let's see how it will turn out in the next days
