Curious if its worth saving battery life to just keep the network on CDMA only during the day ?
I came from Sprint and they had the 4G toggle on most Android devices, I never used it, maybe 05% of the time, WiMax was such a battery hog, and so spotty to ever a hold a solid connection anyways, just seemed like a waste. But Sprints 3G really sucked too, like 1xEdge speeds.
Does keeping the Nexus on LTE cause signal issues ? Meaning does it jump back and forth between 3G and 4G causing dropped calls if you on the phone and move into a non LTE area ?
Thanks

I only bother to switch mine off when I am on my days off from work. I get great 4g signal at work but none at home. I haven't payed close enough attention to battery usage to notice a difference though.
As far as battery life goes, I've found there isn't much difference at all if LTE is on/off. It's the screen that kills the battery. That being the case I don't bother switching it off anymore.
I leave LTE on all day and my battery lasts all day. As long as that's the case I don't pay any attention to battery life. I also never leave 4G coverage though.
I am new to Verizon. Live in the Chicago area, I would assume a big market like this has solid LTE coverage ?
I just know from Sprint, keeping the phone on 4G was a fast battery kill. If left on WiMax you were lucky to get 4 hours on a full charge.
Hopefully LTE is better than WiMax on the battery, I know for sure it way better network coverage.

Yeah better coverage and probably easier to find a signal due to frequency differences.
I use ihtfp69's LTE toggle to turn off LTE/CDMA to just CDMA when I leave work. I live in a pretty poor 3g signal area, so leaving LTE on just drains my battery unnecessarily. I turn it on when I get into the LTE area, works great since it's a widget.

Usually the issue, IMO, is if you are moving between an LTE area and a non-LTE area or if you're at the edge of LTE coverage, so your phone loses its LTE connection, searches, reconnects, etc.
If you've got a solid LTE connection and it's uninterrupted you won't drain battery as fast.
As to whether LTE usage drains your battery faster than 3G usage... I can't say.
I usually leave my lte on unless I know I have to push my battery... coming from sprint evo then photon which are complete battery hogs on 4g due to the joke they call 4g coverage...

The key issue is whether you have a weak or non-existent LTE signal. I find that in some areas such as these if the phone is on LTE I do not get 3G service, or the service goes on and off. If I switch to CDMA only 3G will work much better. I've only used the phone for limited times in areas with strong 4G so I couldn't compare batter life when set for 4G.
I toggle lte off when home, no 4g signal does drain my battery. At work with great 4g signal I toggle it back on. Gives me an excuse to look at the beautiful battery draining screen.

Both phones set to CDMA EVDO only, no LTE radios active. Location is 3G EHRPD enabled, but does not have any 4G towers for miles. I held both phones the exact same way in the exact same location within 30 seconds of each other to record my results.
Signal Test:
Galaxy Nexus 3G Signal Strength: 0-1 bars, -120dbm 99 asu - -100dbm 1 asu
Thunderbolt 3G Signal Strength: 1-3 bars, -94dbm 2 asu - -85dbm 2 asu
Bandwidth Test:
Galaxy Nexus 3G Bandwidth: 0.86mbps down, 0.54mbps up
Thunderbolt 3G Bandwidth: 2.94mbps down, 0.56mbps up
Bandwidth test was the best of 3 runs using www.speakeasy.net/speedtest connecting to New York, NY. Current location is central NJ.
My Galaxy Nexus is running stock 4.0.4 with the newest radios and bootloader, along with Imo's kernel 2.4.1 exp2.
Honestly, after having my Thunderbolt for 8 months, coming to this supposed better phone and having these kind of radio problems is just appalling. The Thunderbolt was always railed for being the pioneer of LTE radios, and for getting weak signal. Well after these tests I am not sure what to believe besides the truth that is sitting in front of me. My brand spanking new Google phone has by far the worst radio I've ever seen in a Verizon smartphone.
I'm going to be hopeful in getting an update that may resolve these radio issues, but the realist in me tells me this is 100% hardware.
I'd like to get some results from other Verizon Galaxy Nexus users running 3G to see what kind of dbm and bar signal, as well as what kind of bandwidth you guys are getting. I am very disappointed and want to know if it's a hardware defect or if this phones radios' really are this bad
Meh. The Qualcomm radios in both of these phones are in fact ****. I think the build of the Galaxy Nexus (whether it be physical or software) has something to do with it. Maybe Samsung herp derped the position of the radios or Google took a **** on the blobs.
Regardless, its a great phone and still gets better data speeds than every other carrier and phone. -coughs- iPhone users -coughs-

Except it doesn't get the best data speeds of any other phones, as my test results conclude.
Even on 4G I've nabbed 40mbps down 15mbps up bandwidth tests on that same exact Thunderbolt when I was in a good signal 4G area. How much have most GN users hit on 4G? 30mbps down?
This phone is a great micro-tablet, but as a phone it is heavily lacking.

Really, cause I have seen people getting upwards of 50mb/s on the Nexus (seems like most of them live in NYC).
Not to mention I was talking about people on other carriers.
Sent from my Galaxy Nexus using XDA
Other carriers is a given, but that really isn't what the point of this comparison is. The point is I'm holding two phones on the same carrier, at the same time, the same way, and one performs multitudes greater performance than the other. Has nothing to do with other carriers.
Fact is this phones radio is junk. You can have a quad core 1080p Super AMOLED Plus screen and 2GB of RAM, the best GPU on the market and 128GB of space, but if it can't hold a signal to save YOUR life, then what good is it at as a phone?
Samsung/Google needs to get on this right now and fix this phones radio. I'm just worried that it can't be fixed through a software OTA...
And I'd also like some speed comparisons, namely 3G, from other Verizon GN users if possible please.
On 3g i used to get about -75 at worst with thunderbolt at my house. Currently getting -93 at best with two different galaxy nexus. Usually worse. Used to have a stable 4g signal too. Now it drops after a few seconds

That sounds about right... very disappointed in these radios.
I get the same -120dbm, 99asu with my Nexus at home, where I would get around 95dbm on my old Tbolt. I think the antenna/radio gives up signal quicker at the fringe distances faster on the Nexus - if I go into a city I get the signal strength I am supposed to get. I have a theory that part of the problem may lie with Verizon's use of old Alltel towers (I'm on the VA/NC border) - The signal in my area is consistently weak, but I've gone to other rural areas & gotten good strength. Perhaps Samsung/VZW will give us a software update on the phones...and perhaps when they upgrade our towers around here for LTE it might straighten up the tower's overall firmware...But we probably wont get LTE here until 2020.

LTE will cover Verizon's current 3G footprint by the end of 2013, FYI.

Hi all,
I am planning to get a note 2 from mobicity here in Australia.
I have the choice of either the 4g LTE version or the 3g version.
My network at the moment doesn't support 4g, so i would only be getting it to future proof it. And i am moving back to England soon, so i might get 4g when I go there.
But if I get the 4g version, I know that 4g LTE uses a lot more battery then the 3g version. But if I disabled 4g in settings (like you can disable 3g on the galaxy s2) would I then get the same battery life as the 3g version? Or would I still get worse battery life?.
I really need to know, as if I would still get worse battery life, I will get the 3g version.
Thanks in advance
Cheers
Corey

The 4G version will chew through it's battery substantially quicker than 3G. You have to ask yourself whether 4G speeds is worth this sacrifice?
Seeing how you don't have 4G coverage anyway, I would stick with the 3G version.
I HATE it when people say they want a 'future proof' phone because:
a)The phone will be outdated (hardware wise) within 12 months and;
b)Most people (particularly on XDA) buy a new phone every year
Now having said all this, the 4G version does have one ace up it's sleeve over the 3G version - DC-HSDPA on 3G. The N7100 doesn't have this (it maxes out at HSPA+).
So, if you did get the 4G, and disabled 4G, you'd *theoretically* get faster speeds than the 'standard' N7100. Assuming of course, that your network supports DC-HSDPA, which I'm not sure Optus does.

Hi,
I don't have 4g coverage at the moment, but i am moving to England soon, and I heard they are starting to roll out 4g there at the moment.
I am only 16, and I am currently un-employed, so i don't have any income, apart from the money my dad gives me, so i can't upgrade my phone each year.
That's why I want to future proof it.
If I do buy the 4g version, and I disabled 4g in settings (I heard the was a option for that in the setting of the n2) then would I get the same battery life as if I had the 3g version? As that should disable the 4g radio. And from what I can find out, the only difference between the 4g and the 3g version is the 4G radio in the lte version.
Thanks
Cheers

Disabling the 4G will give you significant battery life improvement, similar to the N7100.

Ok thanks,
Do you know if it would give the same battery life as the 3g model if I disabled 4g?
As battery life is really important for me, as my current phone is the galaxy s2, and the battery life is terrible on it, I have to recharge 2 to 3 times a day, so no matter which note 2 I get it will be better then that.
But i want to get the best battery life I can.
Thanks

I don't know if anyone can guarantee it will be the same between the two, but no matter how you slice it, you'll still get MUCH better battery life on the N2 than on your S2...even if you keep 4g on...so if you turn it off, it will just be that much better. It's a win win either way.

Actually, 4G is more battery comsume than 3G, but the difference is not so large, auound 10-15%, when you turn off the 4G, the battery performance is same as 3G version.
But the download speed have very big difference between 3g and 4g. I advise you choice LTE version

Here are the facts as i've had both n7100 and n7105.
N7100 gave me 9 to 10 hours on screen battery time almost all the time.
N7105 gives me just over 7 hours. This is 3g only as i'm with 3uk and they only deal with 3g. Their 3g network gives me 19meg download speeds most of the time though.
So a big difference and i actually miss my old n7100 but i'm loving n7105 speeds to. Catch 22 situation. So even with 4g disabled and settings set to 3g only the n7105 radio uses more power.
what is the reason?

Im using the N7105 on "3" in the uk to make use of the DC-HSPA+
Thats specifically why I went for the N7105 because I have unlimited data on that network and the N7100 doesn't support DC.
I use the phone a lot and I easily get a full days use on a single charge and as long as I can do that I don't care as I charge the phone every night.

Well, previously everybody was thinking and seeing that LTE used more power and basically it did. Most of that was attributed to lte using a second board for the radio. As second gen lte radios have been integrated onto soc's it has been noted that lte can be more efficient if utilized properly because with lte's low latency and quick bursts of speed the phone can race to idle quicker. I am sure this is a very effective for people who use sync services a lot. If used properly, I am sure the phone can poll for data in quick bursts and can definitely help battery life. This is not always the case between OEM'S being lazy and sloppy and depending on what and how often the phone needs to poll for data. I would also think if lte has bad reception it can have a worse effect than hspa would. I almost got a carrier version of gnote2 to have lte because I want to test it so bad but I hate my carrier enough as is and I hate bloatware with a passion.

From what I've read they are comparable. But at the same time I've noticed some people getting up to 20% less battery than the international version. A lot of factors go into that like usage and reception. If you really want lte, I would say get it, that is if you really need more than 1.5mb/s more often than not. I turned it down because I am fortunate enough to get up to 5mb/s in ideal situations and 1-3mb/s in less than ideal situations and plenty of WiFi in between.

Make sure the lte bands are compatible and that you have coverage. If you don't have coverage I would just get the n7100. BTW, even though I think Nokia and Motorola by far still make the best phones as far as reception is concerned, Samsung should get an honorable mention for being very battery friendly when signal is poor. Nokia too. Motorola is iffy when it comes to poor signal. And not to mention, the galaxy note 2 gets very good reception for a Samsung phone and by far has the best WiFi reception of any phone I have ever had. Even better than my atrix.

if you buy an 7105 and don't use lte at all, it will probably get a little less battery like i mentioned before. otoh though, it has dc-hspa so it would depend if you get the same as n7100 on your coverage and speeds. anyways, at most you will probably see a 20% loss of what you would see with a 7100. at most. anyways, quit asking for my approval. if you can get an unlocked n7105 and don't mind a small POTENTIAL loss, you should be good to go.
So here is a question, I reside in a city that is not even on the list of getting LTE in next couple of years. So my question is that if I change the setting under Network Mode to CDMA only vs. CDMA/LTE would that save me some battery (since it's not constantly scanning for LTE)?
And are there any side effect to CDMA only when it comes to data quality?
Thanks in advance
I switched mine to CDMA only within a few minutes of turning it on. I haven't had any problems with data. Couldn't say about battery savings, though, as I have no reference point.
Yeah it should save some battery since it's not searching for available lte.

Just and observation on LTE and battery life if you are in an area that has been refarmed to get LTE but may not have the strongest signal for it yet.
I get constant LTE signal wherever I go in Baltimore. Download speeds are great. But the signal isn't super strong yet. So my phone does a lot of pinging the towers to stay connected. That is the yellow signal in my battery graph. This causes a decent amount of battery drain while the phone is asleep.
But 3G signal is great. That is the green line in the battery graph. You can see that when I switched to 3g (or HSPA as it really is) the battery drain while idle reduced dramatically.
So if you are in an area like this and you really need the battery to last longer, put it on 3G and it should help a lot. At least until T Mobile increases the LTE coverage, which I am sure they will.
And for when you need the LTE speed, I have an LTE button on my quick settings panel to activate it so I still get the speed when I need it, but not the battery drain when I don't. (Note, I'm using cm10.1 rom. I am not sure if the TW roms have that quick setting button available. But it can be done in settings.)
This option is not for everyone. But if you are not a heavy data user like me it might be great for you.
