Anyone notice that after installing 2.2 (with the new radio) that the signal strength bars are wacky?
I can go from 3 bars to 0 bars and back in a few seconds while my phone says -100 in network status...
Also, I had a much higher signal strength in pre-OTA, and the leaked OTA than I do in 2.2... (At least if I track the number). This morning I had the phone off charger where before the update I had two bars and a -80 strength. Post update, 0 bars and -102 strength and under Cell Standby it had 80% signal loss....

I have been hearing that the 2.2 leaked rom is bad on battery. This is why.

So far I am seeing better signal reliability than before. I am in an area outside of Seattle... Good signal most everywhere but I work in a building so usually got 1, maybe 2 bars of 1x. Now it is showing 2-3 bars of EV and my data connection is faster at my desk.
I did a *228, option 2 directly after loading the updated ROM.
And no idea who said 2.2 was bad on battery but I am seeing the opposite. Been playing with my phone all day, a LOT more so than normal and still over 80% charge. Usually at about 60% by now with not nearly as much use.
Agreed, I have been downloading apps, using Nexus live wallpaper, browsing internet, texting, took a video and using the HTC Flashlight as well as arranging my home screen all day. Not plugged it in once since 06:56 and I'm at 49%. This is unheard of for me on this phone.
((Admit I did the charge trick when I woke up though))
My dbm is about the same as it was before, but the signal bars are much more accurate and do not fluctuate like the OP states. I was using SkyRaider1.9b but now I just got the new radio and installed leaked OTA. We'll see about battery tomorrow.... 2.2 (no 2.x radio) in skyraider was better than 2.1 Eclair as far as battery. We'll see how 2.2 stock leak OTA works on battery. Give that a few days and then try SkyRaider 2.0.
I'm also pretty excited to see what CM6 turns out like once everything is sorted out.

With full signal, even when idle.
It just seems crazy, i am not sure if this was intended to be an always on service or just on demand.
Which firmware are you on, stock or the update? The update seems to have a much more efficient cell radio.
I am on the update but if i keep 4G (and i have full bar) i see about 20% battery drain per hour.
If i am only using 3G it goes down to about 5%.
Wifi only it is about 3%.
Its probably due to how spotty and new 4g is. Its constantly searching for service. It might say you have full bars but you could be going in and out of 4g coverage.
Ah, that is a bummer. I can't compare, don't have 4g in my area yet. Did notice the wimax radio firmware is about 8MB. Hopefully they can update it to be more efficient. Could be the spottiness of the 4G signal, wimax shouldn't be that much different than 802.11 in theory. I suppose it would require higher transmit power
I've been using USB-tethering over a 3G connection getting anywhere from 0-2 bars in my signal strength indicator at work. The battery level usually remains steady at the same level while I'm tethered.
Now, i'm in Las Vegas and USB-tethering over a 4G connection, with full signal strength. (Does signal strength fluctuate with 4G, or will the signal strength indicator always display "full" in a 4G area?) To my surprise, the battery is actually receiving a net positive charge, as my battery level has steadily increased while I'm USB-tethered.
Also, I notice the phone is cooler to the touch than when I'm USB-tethered over a 3G connection.
Obviously, all of these observations are incidental and anecdotal, but I thought I read previous posts here that 4G drains batteries faster than 3G, but I'm not seeing that being the case.
Is the 3G signal strength a factor for power consumption?
I believe there is a bug with the 3g radio that's causing a higher battery drain. Someone on here was talking about that

I can also say that I too am experiencing the same. 4g doesnt really drain battery that much more (if it is more) than 3g on my Epic. I can go 12 and a half hours with 4g on all day and normal usage...
I find the 4G battery drain consistent moderate drain. You would expect net positive charge while USB tethered as we get 500 ma charging it and no single function can use 500 ma.
4G is still a power hog, and noticeable when not charging, but you are right the amount of 3G cn be pretty bad.
As far as I can tell the 3G seems to draw massive power under poor signal conditions while the 4G doesn't change power, it just slows ,under bad conditions
I have not stringently tested it though, those are just my initial anecdotal impressions.
What I will say is my dormant overnight battery drain has done way up since the last update!
So, I've had pretty awesome battery life with EF02 since I started using it the day it got leaked, but I still heard stories of people getting insane, multi-day battery life.
I couldn't figure out what the difference was between us until today.
I have an Airvana at home and I work in a building that has spotty 3g coverage. I just hooked my phone up to the work wi-fi today and so far, after SIX HOURS and medium usage (work emails, 30 minutes of Doggcatcher, and reading Pulse for about 15 minutes) I'm at 88%.
Yesterday, under almost identical circumstances on 3g I was at just below 50%.
Just letting folks know that the EF02 seems to be "signal hungry" and this can change your battery life drastically.
PS I have background data, sync from work + gmail + facebook, two LP widgets (twitter and FB) and about 30 apps installed.
When you are in a low signal area ALL roms will have bad battery life. EF02/EF10 doesn't seem to be any worse in low signal areas for me, but if I can keep at least 2 bars signal strength on the phone the battery lasts forever.
I had almost 12 hours of life battery with my N4 with 3-4 hours of on screen (auto-brightness) on 4.2.1
after this last update my radio is just unstable.
switching between 3G/2G and goes from 4 bar signal strength to 1 bar or 2 then goes back to 4.
and now i am getting 10 hours of life battery with 2-3 hours.
i am stock rom unrooted.
(i will try to stay unrooted as long as i can )
What happend to the radio. !???
i am now on baseband: 2.0.1700.48
Any key !?
Can't really confirm.
I'm also on stock 4.2.2 and right now I have 19% battery left with a running time of 17h and an on-screen time of 3 1/2h.
So all in all it's quite good.

I actually think the new version give better battery. Check your apps... Some poorly coded app does not work well cross os versions

Yep, batterylife on 4.2.2 definately better than 4.2.1.
Yes on. 48 radio, it's not as hotas . 33 radio..

REALLY !?
i am just using whatsapp, Google+, Instagram and some browsing, That is all
Are you always in a good coverage area !?
Yeah the coverage here is quite excellent. I live in Munich.
But I have to say that I'm not using mail sync and deactivated cell broadcasts.
I am also seeing better battery life on .48 and slightly better speeds, are you using a 4.2.2 rom? if not i recommend that you do.
getting much better battery life as well ... sounds like you have a rogue app causing wakelocks
Mine is much better, too!
I have better battery life with 4.2.2 too, everything stock. I didn't go through whole recharge cycle yet, but after few hours of usage there is quite a big difference. So far so good
Sure thing that i am under 4.2.2
Ok i eill try a reset.

I swear even on 3g battery is lasting so well.

just a heads up:
3% left and 20h 00min usage time and 4h 10min on-screen.

My radio is acting funky at times too, mostly at home. In Network Signal Info the cell keeps changing back and forth between two id's and my signal goes from -95 dB to -110 dB, basically 3 bars to 0 bars, constantly. I think I'm on the edge of two cell towers but this never happened on the old radio. This doesn't happen at work, but there I only get egde but full bars.
Thx for making it clear that i am not crazy.
That was driving me crazy.
It seems that it happens when we have bad signals and there is two towers and it keeps switching between them as you said.
So any solution ?

Nothing that I know of except to downgrade to the older radio. I downloaded a new app OpenSignal to map the towers in my area and see what towers are around me. Unfortunately I'm at work and can't try it yet at home. But it would appear I only have one tower near work and its like 3 miles away.
I should note too that my battery went from 98% at home this morning to 74% once I got to work after a 30 minute commute. It has never drained that fast, I'm usually around 88% by the time I get to work.
Ok lets make it clear,
Now i am in a village in the middle of mountains. There is only one tower, and i didn't leave the house so always connected to Wi-Fi.
I got 11hours of battery life with 4 hours screen on. And 2 hours of Viber calls and tone of whatsapp msgs. ( that's fantastic)
but when i am in the city and there is more than a cell tower my cell phone keep switching between those tower and drain significantly my battery. I get 10 hours of life battery with 2-3 hours of on screen without any viber call, and a moderate msg rate.
Which makes it a huge difference with me, and that only happens when i updated to 4.2.2
I might need a third party app that can help me to choose a cell tower ? Or something like that ?
Sent from my Nexus 4 using xda app-developers app
after the update 19 hrs 4% remaining. 5h 28 min. screen on. 45 min of calls. sync on. half the time on wifi and half on 2g data. i think this is decent battery backup.
what do you say?
I too noticed that it jumps from tower to tower periodically. i have 5 towers within 5 km radius of my home and even if there is a better signal from the tower connected it will jump to the other. is it normal?
I'm getting data drops with new update and never had before update. Wake up phone and all bars are grey including Wi-Fi bars. Never head this happen to me not once on 4.2.1. Weird

I rebooted my phone for the first time yesterday evening (Camera was force closing after setting Aviate as home launcher), after that overnight phone lost 20% charge, before this reboot - phone was loosing 3 to 5% overnight.
I have not installed any new apps, also checked GSam battery monitor and didn't see any app sucking more juice. I was checking different things and noticed network signal strength is much better than normal (95-97 dbm, usually it used to be 103dbm at the same place), checked network mode and it is set as Global instead of LTE/CDMA, I remember it was LTE/CDMA before reboot and my signal was 103dbm.
During the last couple of hours also I am loosing 3 times more battery than normal, so looks like Global network mode is giving better signal compared to LTE/CDMA mode but using more battery. I am all for better signal strength but not at the expense of battery life.
Does any of you noticed similar issue? Does network mode selection has any impact on signal strength & battery life?
Mine is sort of opposite. It had defaulted to global and was at 91% battery being mostly idle for 16 hours. Just switched to CDMA/LTE/EVDO and signal went from >-100 to -97 dBm but could be normal fluctuation range. Will see how it affects battery life but so far it's still at 91% battery having switched over more than an hour ago.
I just checked mine , it showed -81 dBm for LTE. Switched to Global and it went to -75 dBm then right back to -81 dBm.
OK so I'm not sure about dpm, as far as if it's better to have a higher or lower number? But, I did however switch from Global to LTE/CDMA and I'm definitely getting the 4GLTE symbol way more than I was on Global! I was in 3g quiet a bit on Global. And Verizon has excellent reception in my area. I noticed yesterday that my wife was in lte on her iPhone while I was in 3g and we were sitting next to each other. It's much better now.
