When I'm at school (5 days a week) most of my classes are in a building where I do not get a lot of reception, aka, my battery gets killed by the phone to keep up the signal. I do get reception, around 1-2 bars, but that still drains the battery extremely fast. Is there any app or something that I can do to help reduce the amount of battery drain?
I don't want to put the phone into air plane mode because I can still send and receive text messages, but it's just very slow.
Have you tried putting it in cdma only mode?

You could save a lot of battery life by either connecting to a wifi hotspot (if available) or by turning off background data. The problem your phones having is that it has to turn the gain way up on its cellular radio in order to transmit and receive data. By reducing the amount of background data usage (or off loading it to another network with better signal--i.e. wifi) you'll save a lot of juice.
If you can't do either, there are some things you can do with Tasker to reduce data usage to windows of time instead of always on. May be something to consider.

He's in Canada, so using the GSM model.
Give juice defender a try. It used to almost double the battery life on my old X10 when I worked in a building that I could only get 1 bar at best.

JD sucks on the Nexus, unless it has gotten an update since last month.. WiFi doesn't want to reconnect. I've seen others say the same thing.

I realize the release is brand new and has already been pulled but I'm curious to find out what people will think after using it a few days. Have you encountered any improvement or degredation in call quality, data quality, battery life? Sorry about the number of choices but some people think polls are skewed for a result and always say I should have had this or that as an option so I tried to think of as many options as possible since I can not add more choices after the fact.
Battery life hasn't improved for me but could be the rom I'm on (patient Zero )
I don't lose data as much now but still to early to tell. Appears better.
Sent from my Galaxy Nexus using xda premium
Subjectively, seems worse to me, but better handoff to 3g.
Same reception as FA02/FA02. Quicker handoff though. Favors 3G over 4G.
Battery life hasn't really improved nor dbm's. One thing I did notice was 3G to 4G handoff was quicker.

Ditto on that as well. Very sensitive. My 4G is the same as my Razr Maxx and D4. Cross Fingers!
I noticed I had 4G in an area I couldn't before, other than that nothing really changed for me. One of the guys I talk to on G+ says that he never got 4G in his house before and his wifes Rezound always did, but since updating the radios last night he gets 4G inside his home.
I'm still getting random drops from 4G, but the passing off onto 3G seems to be a lot faster. Also I noticed that I get more bars in area where I had less (ex. 2 bars of 4G is now 4 bars of 4G), but still had the same dbms.
Subjectively I feel it helped tremendously. Haven't had a single data drop all day when before I would get several drops a day. I also have better reception.
Why did it get pulled?

I've been on 4.0.4 for months now but I did flash the radios from the official update and my signal is better.

No noticable difference for me. Although my house is right across the street from an LTE tower in a park.

So far I am disappoint.
While the hand offs are faster I'm connected to LTE a lot less now...and previously it seemed that signal in my area was improving ><

dBm is how strong of a signal your phone is getting. (if you want a higher dBm hold it higher/different ) That should be more dependent on hardware than software though, what's sometimes more important is the Signal to Noise Ratio and the Carrier Interference & Noise Ratio (SNR & CINR). Which is basically how easy your phone can hear the tower.
It's like trying to yell across a room that is full of drunk people, whoever you're talking to may be able to hear you yelling but they have no idea what you're saying. Same way for cell phones if you're in a very crowded area.
Something you guys may want to look at. So I was going to test the radios today. I sat here on lean kernel and AOKP and was getting between 86-89dbm of 4G with the new radios which was better but I figured what the hell and flashed the IMM76K build and now I get 71-74dbm with lean kernel. I don't know if everyone is going to see results like this but it is definitely worth a shot if you are seeing low dbm with the new radio.
Speedtest is now giving me 20mb down when the highest I could get before was 12. I know this sounds to good to be true, so don't believe me if you think so but I am just reporting what I am seeing.

I'm not surprised the results are mixed but I was hoping for better.
Radios
For some reason my signal starts off really bad then goes back to normal. I have noticed it favored 3g more so than 4g. Normally on my drive home from work, as soon as i hit the highway it hits 4g, i was a good 10 miles down the road, still showed 3g, so toggled lte off then on and boom back to 4g, albeit weak for a minute then back to normal. Speed tests show slightly faster, but that's negligible for me. Could just be network congestion at the time the other tests were run.
On a side rant i did notice something slightly strange. Installed bamf 1.25 simultaneously on my nexus (had since launch date) and a certified pre-owned replacement for a friend, which of course was freshly rooted by me si the "sd card" was empty other than the roms, and the fresh phone blazed through the installed about 30 seconds quicker than mine and also rebooted faster. I clicked both phones at the same time, both using 5.8.0.0 touch recovery. Nothing to do with the radio, but felt like sharing. Guess i might completely wipe my phone and see if it speeds her up!
I'm on the official JB ROM and have noticed that my device's wifi signal is very low (1 to 2 bars at most) inside the house.
Is there a fix to make the signal stronger or maybe a custom ROM or radio that has stronger wifi?
Thanks in advance for your replies.
U could increase signal strenght using dd-wrt on ur router. Maybe that could help..
I had an iPhone the last two years and with the same router the signal was full all around the house. I really like this device and hope to find a solution.
the wifi antenna is on the bottom half of the phone, hold it at the top and youll see a big improvement. iphone is at the top middle
I also read some time ago that the Nexus show you the "true" signal streangth whilst other devices/manufacturers programs the software to show more bars just the please the costumers eyes. So even though it might look less on a Nexus the actuall speed remains the same as other phones. Don't know if this is true but i like to believe it is

It's a relief if it's true, but I think the problem is there. In the same distance around the house I had signal with the iPhone 4 where GN has none.
I happen to get low bars too, not a lot but I get hella fast downloads than my previously droid incredible. I can download a 100mb file in about 15-25 seconds.
My droid incredible took around 50 seconds to a minute. So I do praise whatever they did to the WiFi performance or it could be the ROM lol..

I have noticed that when I am on 3G, my battery drains very rapidly. Usually like 3% a minute. Is there anyway to fix this, if this is abnormal?

There's no fix to signal related drain. There are only two things that can be fixed really:
1. drain related to apps including unwanted prevention of deep sleep - wakelocks are normal
2. drain related to screen - lower brightness
3g drain is related to signal strength which there is no fix and 3g drains faster than wifi. Also, the older the battery, the less of a charge it can handle. If you're in an exceptionally poor signal area sometimes Verizon can get a signal extender. I haven't dealt with that but I've heard that sometimes happens if signal is bad.

More than likley means that the phone isnt getting a good signal, and is using more battery trying to stay connected. You can try updating to the latest radio, and prl. Has it always done this, or did it just start recently?
Though 3% a minute is really fast. I usually am closer to 1% every minute of two of screen on time depending on signal. Keep in mind battery drain is not linear meaning it may seem to drop off faster at different percentages. I don't know the details of this but this may help:

Thanks tiny and cmlusco. And no cmlusco, it has always done this. I did update my radio to yours (I don't remember which one exactly) and that helped. I'll search how to update prl. And thanks tiny. I'll look into that link.

I feel your pain. I work in an area of Tampa that has zero service and I mean ZERO. My phone tries desperately to cling to a signal and the battery drain is mind blowing. I usually have my phone in airplane mode and switch it off now and then to check for missed calls and what not. One of the roms I was using completely lost 3G and this was while I was at work. I had to change to a different rom after messing around with **778* I couldn't get it back.

It certainly sucks. But i dont really think its Verizons fault. I work on an AirForce Base. Cell phone service is scarce within the whole base. It does seem to be worse for Verizon and Sprint users from the people i had asked about it
Alot of the times my weather app will show totally different locations then where i am, I will pickup the weather forecast for Apollo Beach or Gibsonton(i dont even know where this is)
might be my imagination but i noticed this battery drain using 3G more when i switched to CM10.1(4.21) versus CM10(4.12).
but when on Wifi, my battery usage seems adequate to very good
It is your imagination. ROM has no bearing on 3g drain.

LTE is being developed in my area so I know it'll work sporadically. My question is if I leave the CDMA/LTE/EVDO network mode selected will that have a negative effect on my battery when it's not connecting to LTE or will it be about the same as just CDMA/EVDO?

If it did not connect sometimes toggle the airplane mode on and then off will force it to connect if the tower is on. If towers haven't been turned on there's nothing to do but wait. LTE is awesome.

Yeah, I believe there will be a very slight increase in power usage just because it's searching for LTE every once in a while. Nothing major, you probably won't even notice it. I believe it's almost equivalent to if you have NFC on. But if you actually do connect to LTE your battery will be depleted fairly quickly. But hey, that's what they're for right? Haha

Completely Incorrect being on LTE is like being on Wifi, it's a battery saving. It's not like 4g with wimax which went through battery like it was going out of style. LTE coming on in my area has been the best thing ever.

No he said if you connect to LTE it will deplete the battery and that's incorrect. Under the old wimax 4g that was a true statement. But LTE 4g is as good as being on wifi. When using data on a smartphone your battery life is consumed rather quicker than having data turned off. While on 3g you can watch your battery level go down by the second. But while on wifi you have a much slower draw, and now with LTE 4g it's just as slow of a draw and sometimes even slower adding to how long your device can go without recharging.
My wifi reference is a comparison, as everyone knows that while on wifi your battery last longer.

I have not tested this as I do not live in an area with much LTE, however through searches I have seen exactly 1 time where it says that LTE is a battery saver. And that would be your post.

Well visit the The People's Rom thread and you will find quite a few people that will verify that fact. I have been on solid LTE since November and on both of my devices S3 and Gnex the battery life has done nothing but improve. I never connect to wifi at home anymore since I get better results being on LTE. Trust me when you have it you will enjoy the same benefits. On the wimax 4g it was like multiplying the 3g draw X2 but LTE is completely the opposite.

I wouldn't say LTE is a battery saver, but it doesn't drain your battery like crazy either - not as badly as some people are saying, anyway. LTE drains the battery no faster than 3G, but whether or not it's on par with WiFi, I have no clue. I keep WiFi turned off and rely solely on my mobile network, and I get around 20 hours per charge with 2.5 hours screen on. I'm almost exclusively on 4G since it's mostly complete in the Chicago suburbs, and there is definitely no noticeable battery drain.

On 3g my phones would drain drastically, but since LTE it's like being on wifi or better for me. Whenever I have to go somewhere there is only 3g coverage the drain is almost exactly doubled.

Yeah, that sounds right, I guess. I'm almost never on 3G anymore, and when I am, it's for no more than a couple minutes, then back to 4G goodness, so I really have no point for comparison. My only real point was that some people tell others to turn off LTE in order to save battery power, but the difference is so negligible that it's just easier to leave LTE on. I assume those folks have only experienced 4G through Sprint Wimax or Verizon LTE (the original Verizon LTE phones had terrible battery life while on 4G), so they just assume LTE will drain the battery on any phone, even the S3.
Just an update. There is LTE in my city (on the other side of town away from where I live -_-) and it works amazing! It's not saturated yet but I don't think it'll slow down to much when more people start using it. And unlike WIMAX (which is still here as well) it doesn't use nearly a lot of battery power as I was expecting.
