Some of you are going to say 'that's old news', but for the benefit of people like myself who maybe missed it at the time, I'm going to reiterate from something which was brought up a long time ago in the xda forums, found by accident in posts from a year or two ago.
There's this thing called fast dormancy. It's like a network power saving feature, which some networks don't support, and I found a lot of people saying that when disabled, can actually help battery life on 3G. I'm not going to go into that now, if you want more info Google it..
So it was as simple as adding a line into your build prop. "ro.ril.fast.dormancy.rule" with a value of "0" and rebooting.
I wasn't expecting much, but did it just for the hell of it. I've not really used my 3G data much since I did this about 4 hours ago, but I left my data switched on, which is usually enough to drain the battery a bit anyway, I'd expect to lose 7 or 8 percent normally just being connected to data. Just checked battery drain. Hasn't moved 1%??!?! UPDATE: It is still using a bit, but definitely seems better.
Also..... I've speed tested my data many times before. Usually in my house, from sitting in the same chair, in the same room, I always get say 2Mb plus or minus 0.5 Mb. Well guess what. I ran a speed test and got 5.5Mb!!! So I ran a few more and it never went below 4Mb.
Can someone please shed some light on wtf is going on here? lol
Edit: just ran another speed test. 5.26 down, 1.25 up. Something has changed here, I'm telling you. Maybe o2 have switched on a new mast right outside my window ( just kidding, there's no new masts, because there's a mast fairly close to me, I know where it is)... I've ran loads of these tests with the same phone, same network, same room, and same ROM before, and never got half of the speeds that I'm consistently hitting now. Maybe the network has been upgraded or something and its just coincidental, that wouldn't explain why my battery life on 3G does seem to be improved though..

Anybody else fancy running a speed test, adding the line into your build prop, then rebooting, trying another speed test, and checking out your 3G battery life as well?

Tried it but unfortunately no noticeable difference in my case (on KPN network in NL). Thanks for the suggestion tho!
No problem. Maybe there has been some kind of improvement made to my network then. After having a think about it, if I am now getting a much better signal than I was it would actually explain the increase in speed (obviously), but also it may explain the battery life increase too due to my phone not hunting for a signal as much.
That's why I was wanting someone else to try, so thanks. I didn't realise it was possible in the real world to get 5.5 megabits from HSDPA. I wonder what the theoretical maximum is from it, and the real world maximum..

The image speaks for itself, but I'll add some info. I have a SetCPU profile for screen off that sets it to 245 min and max, and I haven't been using the phone hardly at all the past two days. Wifi has been on the entire time.
Normally, after 8 hours of light use, my phone would be dead with Android System taking up about 40% of the battery, and the three radio entries taking up about 16% each.
I've been using CyanogenMod 6.1.1 since the day it came out, with it's built-in kernel, not Pershoot's. I've done nothing else custom. The only thing that I can correlate with this change in battery life is a new version of SetCPU came out a couple days ago.
Or maybe it's just an unrelated fluke, and tomorrow whatever battery-eating bug exists in the system will rear its ugly head again. I dunno. All I know is I've never seen battery life like this on my G2.
101% yaaaaay I can add

Screen not even registering as using any?
most of my usage is screen for 60%+ (maybe 2 hrs on)
and 15~18 hours tops!
You still geting great battery life I have the same setup and battery life is average not as good as 6.1
I do not mean to highjack your thread but I have a question. For the cell standby power consumption, what is registered as the amount of time with no signal? I am in a full HSPA+ area and it still tells me that 50% of the time my phone has no signal, how is that possible? Thank you for your responses.
I managed 56 or 59 hours once and the display wasn't on the list either. I mentioned this in another thread but it was generally ridiculed and dismissed
i lose about 50% of battery with hspa on during a 8 hour shift. Of course random facebook and texting is going on.
I noticed an improved battery life with the unofficial Gingerbread builds. Did Google finally get it right?

That has been my experience, though I'm still stuck using the stock HTC sense since I updated to 1.72 before rooting.
Whenever I check battery use, the Display is ALWAYS the highest consumer, by a large margin. I usually see 60-70% Display, and the cell standby, etc are only a few percent. Now I'm really upset I can't root it for the forseeable future.
Did you just not ever touch the phone at all? I mean, the display isn't even listed!!?!?
As I said, I was barely using the phone at all.
Right now I'm at 95% after 10 hours of non-use. I don't remember this ever being possible in the past.
Even when I actively use the phone (at least in the past) Display would never be very high. Android System was always #1 with the radios beneath that, and Display somewhere around 6%, as I recall.
In the time it took me to write this post mostly in Swype, I lost 2% so my crazy battery life seems limited to the screen being off (with the corresponding very low cpu speed). Still, it's never been this good before.

I bet the lcd being not used plus wifi instead of 3G is the reason. Plus, I think it's witchery not wizardry, lol! Maybe both... whatever they are both hilarious! Ah, the days of yore!
Hey, can somebody post a screen with their top speed (wifi) from their phone? I'm curious what real-world performance is between the "42mbps" radios is.
Ps-my home internet is rated at 18meg, so with devices connected, this is probably most of the pipe.

How can you have a WiFI speed test .
Its dependant upon the speed of the users connection and those are many and varied 3meg can be a good connection for some .
Mine is within about 1% next to the router but drops the further i move away .

Not a flame, but what are you talking about?
Wi-Fi has nothing to do with what the "42mbps" radio is. That is HSPA+, and is not in use when Wi-Fi is connected. And it is totally dependent on your carrier, and their APN.
On AT&T, H+ can be different depending on which APN you are on - either "wap.cingular", "phone", or "pta".
If you are connected to Wi-Fi, your speed will be totally dependent on your Wi-Fi connection's speed, and will have nothing to do with the HSPA+ radio or your carrier.
Processor? What I know is this - my Sensation can't pull these numbers over WiFi. I realize that it's not the best test, because it is not cell data. However, I wanted to see what kind of throughput my phone is capable of, and how an S2 does. And yeah, internet speeds differ, but somebody out there has an S2 and WiFi as fast as mine. I suppose my curiosity is more toward "does it utilize it fully" more than "I live by a tower and my cell speed is X" - which seems far more arbitrary to me.

No offense, but this is worse than arbitrary. You have no way of knowing if someone else's Wi-Fi is the same speed as yours, which already makes this "test" invalid.
If you want to know a true comparison between S2 Wi-Fi performance vs Amaze Wi-Fi performance, you'll need the two phones side-by-side hooked up to the same Wi-Fi.
My s2 pulls from 10Mb to 24Mb
Connection is 50Mb

It goes quite fast
SGS2 BT infinity fttc
My ISP is 100mbps
With wired PC I get ~90mbps down and ~80mbps up
So phone results are not very good
Quick question to the pro's
Whilst I haven't put a SIM card in my lovely new N4 yet (awaiting mico SIM from Vodafone) I thought I would set it up over WiFi.
I can connect to my router, home network and home server fine, but it is just sooooo slow and continually timesout. I have changed the settings, frequencies etc, restored router to factory settings and back to saved profile, but nothing seems to help.
Play store spits me out, and I have reset the N4 to factory 3 times now.
I will try on other Wifi networks over the weekend, and on mobile data when SIM card arrives, but was just wondering if I am doing something obvious wrong or it other have have similar experiences?
thanks
edit.......I did manage to do a system update, and now on 4.2.1
In my experience it is really fast. I get 30mbps down, as fast as I get on my desktop.

My N4 connects nicely to the router as follows from the settings
Status - Connected
Signal Strength - Excellent
Link Speed - 72Mbps
Thinking (hoping) it the talktalk router, as since I updated the firmware I have had other problems...........need to test elsewhere I think first!
Thanks
wifi issue is for sure
Look at other posts you will find many people are having wifi issues. I don't think you did anything wrong, it is just the problem of nexus 4.
Let's wish google would fix it soon.

Thanks, did find a limited number of similar issues listed when I did a basic google search, but hoping it was something else.
SGS2 in one hand works lovely, N4 in the other not!
As I didn't manage to test test it before the update to 4.2.1 I don't know if this release is the issue!

This issue was starting to annoy my experience with the N4 tbh
I just changed my router back to my old one to test, and its now working perfectly!!!! Others have reported issues with D-Link routers, of which the one I was using was a Talktalk supplied D-Link.
Lightening quick now........
My battery life is crap. I replaced the original 2 year old battery a few weeks ago, and still no improvements. I am using SIMPLEAOSP right now, with the default kernel it comes with.
I have to get something different. I am getting like 12 hours of mild usage before I need to find a wall. That is unacceptable. I have done all of the battery tweaks I can do within 4.4.4 and still keep most of my daily functionality (disabling NFC, low accuracy GPS, etc).
What would you guys recommend I try. I am tempted to just hold out until L is released, but I cannot keep living like this (firstworldproblems). I was just going to buy a N6, but it is WAY too big and WAY too expensive.

It could be many things, your signal strength, your apps, your usage, or your wakelocks. Provide information about this and then come back to us.

Woah.
Wakelock detector + Greenify can find and put to sleep what's keeping your phone awake.
Wipe your phone and return to stock. Flash your ROM and don't use google now. But honestly you probably just need to put your phone down.

I do use google now, but I actually like it. But that hasn't changed, and my battery life has.
I am hoping that wakelock + greenify can figure it out, because after replacing the battery I have had ZERO improvement. Which leads me to think it is ROM/app related.
Today I flashed a new ROM (purity) and threw franco's kernel on. The testing will resume.
One a more interesting note, today during my battery life searches I ran upon a thread about T-mobile using significantly less battery during the day, compared to AT&T. http://blog.laptopmag.com/tmobile-phones-longer-battery-life
I did recently go from the $30 T-mobile plan the a $45 straight talk plan using AT&T. I wonder if that is making an impact as well.
So yea...I am working on it. WOAH!
Kind of the same problem here, received new battery today but my Torx is too big! Have to get one that fits.. but i suspect that the main problem is the battery drain in standby/deepsleep. I can get to 90-120minutes of DOT, that was never much better, but what the phone is doing while i don't use it is the problem. I tried BBS, WLD, CPU Spy and Greenify.. but i suspect that some google background service is the bad boy.
HI everyone. I'm using Cricket Wireless on my Verizon Galaxy S7(G930V) running the G930U software. So I'm getting 4g LTE. But the cellular signal is TERRIBLE inside my house (1-2 Bars max) with this phone when compared to my Unlocked T-Mobile Note 4 that I was using before this S7 (I was getting 3-4 bars). I only switched to the S7 because we had the phone laying around and My screen on the Note4 stopped working out of nowhere. I plan to move back to another Note4 as soon as possible. But for now I'm stuck with this S7. Any reason as to why my signal would be so poor on this particular device compared to my older Note4? Anything I can do about it?.
The indicator bars might be lower, but are the actual speeds your seeing any worse?
Speeds are decent.
I never did a speed test on the note 4 to compare with.
But this phone loads pages the same comparably when on 4g here in house.
Its gotta be what is killing my battery tho.

Battery life is Terrible. I'm on a mission to get that better right now because this will not work for me. I'm used to having 4 battery's and being able to use a separate Battery charger. Note 4 spoiled me with that and the IRblaster.

WTF is going on with my battery? I have the S7 Flat snapdragon version (G930v) running the G930u software unrooted which removes all carrier bloat. Screen brightness is set to a little past half way. I have all setting provided by stock software optimized for maximum battery life other than running AOD. I am running a black Wallpaper/Lockscreen/ and an All black theme from the Theme Engine.. I Repeat, I have all stock firmware options Optimized for battery. Every single one. Wth hell is going on here. My battery time is looking Rediculous in comparison. Someone help me out here.

I feel asleep around 3am I guess with 89% and woke up just now close to 11. Heres battery over that 8hr period. 5% during that time. Standby drain is not bad it seems. But only 10hrs on 100% is crazy low compared to what some of you guys are getting.
