I got this much today and I feel happy with it. I got up at 6, had school and text in crappy service for whiles at a time. I did charge It once but for like ten minutes. Stock everything, do I get good battery?

It is possible to get better battery performance than that, but as long as it's suitable for what you need it for, then that's the important thing.
If you're interested, there's always lots of information in threads about custom ROMs and custom kernels regarding the amount of battery people manage to wring out of their phones.
Could be improved. Have you checked your phone for wakelocks to see if there is any apps or services eating up unnecessary battery? Try flashing a kernel/ROM as well. Highly recommend Franco's kernel.
These are screens captured this evening. Using Franco's r121 kernel and stock ICS IMM76I on stock 1750mAH battery.
Thank you! Will try it. Can I just flash in recovery on completely stock rom? I want to make sure it's compatible

1hr 42 minz of screen on time isnt so hot. a 3hr average is considered decent
i wish i could get past 6hrs of battery life with playing music.. im thinking about buying a extended battery
and yes im using Franco m3, AOKP 34

Yeah everyone is comparing apples and oranges, Wifi and Wireless, LTE and GSM, etc..
Yes you will get almost 2 days of battery life if you are on a strong WiFi signal the majority of the time. If you understand wireless technology it all makes sense. Regardless of the signal wifi or network connection when the signal is weak the phone is using more power to keep the connection alive. In turns of power usage Wifi uses less power than 3G which uses less power than 4G. For LTE devices here usually how your battery life ranks 1 being the best.
1. WiFi signal 4-5 Bars
2. WiFi signal - 2 - 3 Bars
3. 3G Signal - 4-5 Bars
4. 4G Signal - 4-5 Bars
5. 3G Signal - 2-3 Bars
6. 4G Signal - 2-3 Bars

I don't know yet about the Nexus specifically, but in most cases it's much easier on the battery to idle on UMTS than WiFi. However, since most of us have our phones in constant contact with the Googleplex, there's a fair amount of data transfer when the phone is otherwise idle. That muddies the waters quite a bit.
It also depends to a large degree on whether your AP can allow WiFi clients to sleep like they do on the cellular networks or not. I'm not positive about cdma2000, but in GSM and UMTS the phone spends most of its idle time with the radio off. It only has to wake up every 5-10 seconds to listen for pages from the network.
Some WiFi APs have working 802.11e WMM, but others are broken. Presumably anything modern is more likely to have working power save, but it's always been hit-or-miss for me despite the standard being some 7 years old now.
If there's a point to take from this, I guess it's that whether wifi or 3G drains your battery less isn't something you can make a blanket statement about, as with almost everything related to battery life.

Overall, WiFi uses less power than 3G/4G. WiFi uses more "idle" power keeping connected, but much much less "transmitting" power. It transmits for shorter periods of time (short active connection) and over a shorter distance (no power to boost signal), both reducing usage.
Even if it was break-even power wise, you'd rather be on WiFi to save data usage.

Guys, the GNex I am using is VZW LTE device.
I know its battery issue and have been playing around to find the best balance to use both LTE/all awesome features while keeping the phone alive for sometime.
So far my set up ,before I went bed yesterday, was pretty satisfactory: Franco kernel 15.1 + Gummy 0.7 + Hybrid Radio .
Before I go sleep, it has 31%.
This morning, after 5.5 hours sleeping, I press the phone. It is DEAD, seems long time ago.
Took a screenshot of the battery usage, here it is

Any idea why this may be the case?
I tried to look at the wakelock info but because the phone was dead, I can't really see what was there using "since unplug".
May run it down today and monitor why =((
Well, the last drop was when you seemed to have a really bad signal for some reason and the first drop was when you were actively using the device, so you should look at the apps you were using and what you were doing at the time. Outside of these two drops the device had a normal signal and normal battery drop.

Same has happened to me, and a few others. There are posts about it on Androidcentral. Basically the phone drops the network then spends the rest of its battery trying to reconnect to it. Its possibly an authentication issue. It has happened twice to me. It doesnt happen if you leave the phone in 3G mode. Even with WiFi on, it can happen, because the phone still needs to maintain network connection for phones and data. This is on the LTE Nexus,

With low/no signal, the phone boosts power to the radio and tries to search for the signal. This is normal cellular phone operation and has been for many years.
It's a pretty big drop, but as has been said you can really hammer your battery when your device is searching for signal.
I notice that your screenshot shows wifi on.
Franco 15.1 had a faulty wifi driver that was sapping people's batteries. This is fixed in 15.2. Flash your Franco to 15.2 and those problems should go away immediately. My idle drain is now 2mA.
Have you tried Juice Defender? Give it a shot. It is a big help with standby drain.

A lot.
I usually lose 3-4% over night (9h) with perfect reception. Last x-mas I was at my gf's home on the countryside with barely 1 bar of reception and ~50% no reception: Lost 30% over night. Both times connected to WiFi.
I feel your pain... though mine is not as nearly as bad as yours.
Do you have the option to connect to wifi at work? That should help if it's available (and/or allowed).

I'm not the OP, but having WIFI doesn't help/hurt my battery life at all when the phone is idle. I also have bad reception at work (and at home), but not nearly as bad as the OP. Even with my poor reception at home, I only lose about 1% an hour at night with about -90dbm of service.

Battery life with great signal and hardly any congestion is almost comparable to wifi. During Xmas break there were hardly any people downtown Houston and I got almost 5 hours display twice with ~10% left still.

In that context, you're correct. -90dbm isn't the best of signal service but it's not equivalent to having no service period (per OP's 60% missing signal) But I'll disagree on the front that it does not help battery life if he's missing signal 60% of the time.
Case in point, I get absolutely no data reception at my mother's house. Phone itself is constantly searching for service which has been a huge battery drain; idle or not.
That 60% he's not having any signal, phone (and consequently apps that are also trying to utilize data) do contribute to a big battery drain.
Being on WiFi remedies that a bit.

Your phone is likely defective and you should exchange it.
I used to have high % of time without signal like that... then I exchanged my GN for a new one and it's got signal close 100% of the time.
Do you drop connection when trying to use data?

I tried that with my first phone... It made no difference.
The lady I talked to at verizon support was pretty open that there was a batch of bad GNs out there. Definitely no harm in trying a new radio.. but don't wait too long if it continues to perform like that.
The difference between my old and new phones are night and day. Old one would drop connection every 20 minutes (and usually more often than that). The new one hasn't dropped connection one time in over a week
Get the app called No Bars that puts your phone into airplane mode after how ever many minutes you want after the phone doesn't have signal. The app also has a setting to to automatically keep checking for a signal after how ever long you want it to. I used this on my EVO4G with Sprint but I don't think I need it any more with verizon so I don't know if it works on our phones.
It's definitely because of my office. However, I had a droid x that had better/stronger signal than my GN. I just flashed the 4.0.4 radio that came w/ Codename's latest ROM. Bars appear to be one notch higher on 3g, (0 bars to 1 bar). But the signal strength is exactly the same.
This is my first full day on 4.0.4 radios and my battery is fantastic. I was dropping 2%/hr. I seriously was wowed by how awesome its been today. Although, every once and a while, my phone does that.
Very pleased. The big drop was grooveshark steaming on 4G.

+1 for turning off 4G when you are out of range. Also I enabled the mobile data limit and forced several applications to restrict background data. For example, google+ was a major hog that was constantly using the radio. Also check applications that "check in" periodicaly, and increase their check in time. Words with Friends checks in every 5mins by default.

My battery died in a few hrs today and the culprit seems to be 66% cell standby. I've never experienced this kind of drain before. I'm running the latest Franco Kernel and I'm wondering if anyone else is seeing this?
I just posted something exactly like this earlier in the day. Do you have google chrome and recently updated? I think when I just uninstalled it, it fixed my problem...

Leave your screen on all of the time. It will make the cell standby percentage go down .
On a serious note. what's the time without signal? Just press on cell standby and it will tell you the percentage I think. It sounds like you didn't have coverage and your phone was constantly trying to find it...which would kill your battery fairly fast and probably make your phone warm in my experience.

What did your network level look like over that drain? It looks like you have bad signal, but it shouldn't effect it that much if you're on WiFi the whole time... as noted before, a radio constantly hunting for better 3G/4G signal can really drain the battery.
How much screen on time was that? Probably pretty low?
56% of the time you were without a signal? Where do you live? Alaska? On a serious note though...I'd recommend switching to 2g/3g or wifi when you're having trouble finding a signal.

So it is true that when your phone did not have network connection, it will constantly find coverage and thus account for the awake time in the battery state? Therefore eating up the battery life, even though the screen is off?

He said the wifi was off, please read people.
not sure if "insane" means bad or good. But it looks about average. The average screen on time ranges from 3.5 to 4.5 hours. Mine is dead center of that.
Bluetooth not connecting to anything still drains a lot because it is constantly scanning for other bluetooth devices.
BTW your reception is in the YEllow. that means that also leads to battery drain.
So if you have better reception and your bluetooth is off then your battery would last longer.
Note: I use bluetooth a lot and I find it to be one of the biggest factors for draining. more than GPS and Wifi. Although, using wifi with strong signal actually saves battery.

You're doubting that our phone doesn't last that... Uhh.. Short? I've had this phone since December and had many discussions with others on here about it and we agree that 4 hrs is about right.
So with that test you're saying that our phone can get over 6 hours throughout the say with normal use? Highly doubt it. You have to realize a couple things.
1. Wifi consumes less battery than 4g
2. You should factor in a normal days use that means including idle time i would say about 2% per hour maybe less.
3. Watching a movie means no "touch" interactions which means it consumes less battery than Web browsing or playing games.
So yes if you just leave the phone on the entire time without touching it. It'll last a long time. But with actually interacting with the phone and using 4g data. Most gets 4hr. Screen time in 17 hours of use ( you guys do get 7 hours of sleep right?)
I don't really believe that test. I know that the 4s battery sucks balls. Our phone lasts longer with our 4g on. It is saying that the one x is shorter?? One x and s lasts longer than our phone. So yeah.

Hi guys, I'm a happy Nexus 5X owner, except for one thing: battery autonomy.
I had a true hope that Nougat would change my perception, but I got no improvement at all. After that I tried ElementalX kernel running every profile, including the newest GlassFish 1.2 and HawkTail 1.2. I also use Greenify and don't have facebook app installed.
I unplug my phone everyday at 7:30 AM and it can't get past 2:00 PM. My use is *only* web browsing (chrome) and whatsapp. Nothing like youtube, netflix, gaming or listening to music. I get only 2h30 SOT.
I've been using this charger for about 4 months: http://www.gearbest.com/chargers-cables/pp_350509.html
My question is: could my battery have been damaged?
Thanks!
Probably just the usual combination of Usage, Settings and Signal. We could only guess without some screenshots though, there's a battery life thread in General where you can post them and get advice.
The one thing I can suggest to evryeveryoneone is to use Developer Options > Running services and see which of your 3rd party apps are running 24/7 in the background. These are using your phones resources even if you never launch the app.
Nothing special is needed to get good battery life on this device, I typically see 5-6 hours SoT over 24-48 hours with stock 7.0. No root or loss of features.

Honestly, whats your brightness? Do you use bluetooth? Is NFC turned on? Location? Are you running 2G/3G or LTE? WIFI? Do you have wakelocks? I can make my nexus have 3 hours SoT ober a day also. But I can also make it have 5. Its all usage dude, unless you see a lot of heat, or drops of 5% over 5 mins, id say you battery is fine. Maybe its just the charger that doesnt fill it right? Why do you use that charger?

Honestly, whats your brightness? Do you use bluetooth? Is NFC turned on? Location? Are you running 2G/3G or LTE? WIFI? Do you have wakelocks? I can make my nexus have 3 hours SoT ober a day also. But I can also make it have 5. Its all usage dude, unless you see a lot of heat, or drops of 5% over 5 mins, id say you battery is fine. Maybe its just the charger that doesnt fill it right? Why do you use that charger?

I use auto-brightness (usually 50%). No bluetooth, no NFC, location battery-saving. I run half time 3G, half time WiFi. I use this cheap charger at work. The original I use at home. My wakelocks from yesterday are the following:

Thats actually normal considering you have auto brightness and half the time on 3g. However, your whatsapp usage is huge. Try running withouth it for a day. And do you really need location? How is your signal strength?

Auto brightness consumes that much power? What's your recommendation?
Signal strength is always strong. I'm turning off location from now on.

Hell yea. If you have it on 50% and use your phone anywhere outside or somwhere where the phone determines that you cant see it clearly, it will crank up the brightness, and that consumes a lot of battery. Try running it on 10-15% manual mode inside, and 20-25% outside or more if you really cant see, but keep the brightness mostly to 25%. The screen consumes a lot and plus 3g, no wonder you have such bad battery life :/ On 10% brightness, you can pull off 4 hours for sure. At least I can
