Hi Everyone,
Just a bit of background, I've had my nexus 4 for just over 24 hours, and trimmed my old SIM card down to fit whilst waiting for a new one to be delivered from my provider. Last night my provider cut off my old sim, even though the new one hadn't been delivered, so as a result the phone was left with no mobile signal, but was still connected to wifi and bluetooth.
This was my first full day with the Nexus4, and I'd noticed the battery drained quite a lot quicker than my Gnex (with similar usage throughout the day), but once the sim was cut off, battery use levelled off significantly, despite still using the phone, and downloading playlists for offline use with spotify.
You can see below (where the mobile signal goes red) when the SIM got cut off, and despite spotify still downloading in the background, the battery drain slowed significantly. I should add that live very close to the cell tower, and always get excellent signal strength.
So I was wondering, could the radio be using more power than it should and contributing to poor battery life even in good signal areas?

I'm wondering the same thing. I disabled my cell service and just used WiFi yesterday because I was in an area with no cell signal. With the same amount of use and data syncing, the battery lasted MUCH longer. It was night and day.

Ok i have been doing some battery monitoring for these past 2 days and these are the result i got. Only 9% battery left now after unplugged for almost 47 hours

Time spent without sleeping : 7h 13m 56s
Screen on : 3h 07m 13s
Wifi on : 1h 32m 35s
About half and hour of gaming, 1 hour data connection, sync of blur accounts on
I would say my battery life is pretty great
What Rom/kernal?

I'll pass with Edge. What can you get with 3G on 24/7?...

If your data connection isn't on, you're not syncing. Did you mean 1 hour of browsing? Are you using "battery saver" mode, which kills data connections after 15 mins?
If I put my phone in airplane mode and didn't turn it on it would last all week but it would be pretty useless.
Yes 1 hour of browsing through 3g data. Of course i didn't on it 24/7 it gets hot in my pocket and considering i come from tropical rainforest part of the world, its even hotter lol
I reckon that's pretty much average to be honest.
You got 2 days but your screen is hardly on.
Stock ROM, unlocked and rooted, flashed LTE enabler zip. Still on JWR66V.
Charged phone yesterday, went out, when I got home it was still around 70% battery so I did not put it in the charger. Woke up, tried to open Facebook messenger to read a message, app took a bit to load, so I just closed it and put the phone down. When I looked again, it was at 18% battery. Hardly used it.

Any ideas? Took it off the charger about an hour ago at 91% now at 79 with little use.

Why would either of those things cause a battery drain like that?
Seems a little less since a shut down and restart. But still curious..?
You have Google Services battery drain. Check http://forum.xda-developers.com/showthread.php?t=2385843
Yeah, also make sure currents isn't auto updating..
Anything pulling data on a regular basis will use battery.. Notifications, etc because they cause the app to basically run all the time.

I get all that. I've never seen this much of a battery drop while the phone was idle.
Yeah, all my sync is on and i'm constantly connected to wifi. Never seen a idle drop that much.
[My new Galaxy S5 does not seem to be getting great signal reception. It's constantly around -100-106 dbm. I downloaded an app that checks it every 1 minute and then produces the results in excel forumat. Other devices in my office (also on verizon) are getting much better reception
I went to the mall, and the Galaxy S5 there was around -80, while mine was -97. Obviously both Verizon. How is this possible, other than a faulty radio in my device?
I remember back in the day you could dial #228, but obviously with 4G you can not do that.
Should I return/exchange my phone?
I should add, if I power off the phone, take out the sim card, then reinsert it. The signal improves to like-84-88 dbm for awhile, then tapers off again to the -100s.
Will SOMEONE chime in their thoughts?
You can see in the circled area, if I do a restart, the signal is better for like 5-10 mins, then drops off again. I even tried to do all of these things in safe mode, same results.

Maybe you should check the signal power when you actually use your phone ( in a call) maybe is a power saving feature. Try to compare with other s5 in the same room. Could be a bad driver for modem. From my experience with Samsung it takes 2 or 3 updates to get all well.

Disclaimer: This may be common knowledge for many people, but for those not in the know or new to Google Fi, there are some great features you can take advantage of to save battery life and data usage.
So what is it?
The passed ~24 hours, I've been testing a combination of settings that saves battery usage without interfering with service (tx and rx calls and texts).
There is but one requirement: Have access to a Wi-Fi network. Then, all one must do is (in this order):
Turn on Airplane Mode
Turn on Wifi
Seriously, try it out. You'll still be able to send and receive both MMS and SMS, and as long as you have Hangouts enabled (you don't have to use this dreadful app, you just can't have it disabled), you can make and receive calls as well. Airplane mode cuts down on the battery usage by shutting off the radios in the phone for Bluetooth, Cell Service, GPS and WiFi. However, WiFi can still be enabled with Airplane mode enabled due to some airlines offering WiFi during flights. Unfortunately, this technique requires that you been in range of a WiFi signal that you can connect to. So obviously this technique won't be applicable when on the go.
Results
As I said before, I've tried this for a little less than 24 hours and battery life has been pretty solid. I left the house a little today to hit the gym and run some errands, hence the blip of cellular network signal.

2.5 Hours of Screen on Time at 80% brightness and as of posting this, I still have 41% battery left.
I've had the g4 for about a week now and have noticed that my battery is draining by 30-40% over night. I've reset my phone yet the issue still seems to remain. Going into the battery menu under settings, it shows that the majority is being taken up by mobile standby.
Here are a few snaps from the settings/battery.

Some of that data drain could be coming from a weak signal. On poor reception, the device spends a lot of power to find a better/stronger signal and if you're in marginal areas a lot, then it's going to use more battery. There are apps that will automatically switch the phone to airplane mode and apps that will switch the signal off and on depending on signal strength. There was one I use some time ago that I'm not sure if it even exists any longer is ShutUpBatterySaver. It would switch data on and off depending on what you set it for. Another two were Autopilot4 and NoBars. You could also just turn your data off when you know you won't need it.
Try uninstalling Google Photos. I noticed a very high CPU utilization. Not visible in battery uses (why anyway?)
Even used in "local" without synchronization.
Instead, enable the embedded file manager (in the list of disabled application, it's pre-installed), and update it in Play Store.
It looks like ur signal is weak too. Try to switch to 3G and your signal should be a little stronger

Hello everyone! I have the same issue with my moto g4 (xt1622).
Signal seems always bad even when the phone displays 4g in full strength! If you look at the screenshot seems that the signal became bad only when screen is off! Is that an hardware problem or an Android bug?
Thanks
