I'm curious about switching from lte to 3g, will i really save any battery? Or do I need to install a custom modem?

i get my best battery life on lte. i had the n4, it doesnt officially come with lte, but can be enabled. anyways, as soon as i started using lte on my n4, i gained an hour of screen on time as opposed to using 3G(hspa+). i want from 4 hours screen on time, to 5 hours. and on my nexus 5, i use lte exclusively, i dont even ever use wifi, and i see 5-6 hours screen on time every day. then again, it would depend on your signal quality.
In my house I have 4/4 bars signal with H and 2/4 bars with LTE.
In that case LTE is still the best option?

it can be. generally, when using data, lte is more efficient. it spends less time downloading/uploading, therefor uses less battery. if data speeds are better using lte than they are with your 3g, then lte would be better to use.
I have more battery drain on lte... I think 3g is faster enough
The fastest connection with the best signal should save you the most battery.
Wifi is much shorter range so needs less power to maintain a connection. Considering most people have fast Wifi it will usually be the most efficient.

I had the best battery on LTE when I went to London for a few days. Gained a hour screen on time easily with very strong coverage throughout most of central London apart from the underground obviously lol

i did an experiment on lte/3G battery life in the trinity thread a few days ago, same usage and setup. on lte i had 5.5h sot, on 3G(h/h+) i had 4.5h sot. using lte gains me an hour sot, using 3G i lose an hour sot.

When using a 3G connection does it constantly jump between 3G and H+ for you also? Seems to be based on load and I'm assuming normal operation.
I need to keep testing this but lately I am finding 3G/H+ (7-15Mbps) connection to be similar in battery use to my older wireless G (15Mbps) network.

for me it jumps from h to h+ when i access data, but thats how its supposed to work. the 3G/H will be used when not needing to access data, H+ will be used when accessing data, unless H+ isnt available. besides that, it doesnt jump back and forth at all.
In my case I'm having better battery with HSPA than with LTE.
The thing is...here in my house I have yellow/brown 4G signal and green 3G signal.
In a long deep sleep time (at nights) 4G consumes a bit more than 3G.
But during the day the difference is a little more significant.
I can get 4 hours of SoT with 3G. But 3 hours with LTE (or 3 hours and half).
I'm pretty sure that with a perfect LTE signal I would even have better battery life (like almost 5 hours of SoT).
But here is still experimental.

Anyone else having this ISSUE? My last phones all had like 4-6% standby time on the battery. But this g2x has been 64-83%. If this can get fixed I think my battery will be much much better!
What can be causing this?
when you say 64-83% how many hours has it been in standby? What else is using the battery? I know the G2X in my office has like 70% standby but that's standby from 14 hours and it's still at 92% battery life. (work phone so pretty much just sitting in the office until we need it)
Standby usually drains faster if you're in an area with no cell signal from what I've noticed.

This is very important to note. As the signal gets lower, your antenna has to increase power to maintain a connection with the tower. The lower your signal, the more battery required to keep a connection
My cell standby has been alot more then my display and I don't have it in standby. What is odd. My network connection says utms yet I have 4g showing and speedtest is 4-7mb dl. I can unplug my phone leave it on for an hour loose about 15-20% battery with it like at 70%+ cell standby. It's odd...
Maybe it's the 4g cell struggling to connect?

I have the same widgets on the G2x that I have on my Nexus S. I have pure calendar and pure calendar agenda both set to update when the calendar updates. I am still leaning towards more with the 4G struggeling or something.
I've always thought umts was pure 3G while hspa was an update to that which in turn you could get the hspa+. However my connection always says umts, yet I do get way above 3mb dl on the speedtest. It always gets between 4-7mb dl.
The battery life on this android reminds me of when I had the Eris, just blah!!

I have the EXACT same issue with cell standby. I think it's the 4g connection as mine is constantly switching between 4g and 2g (never 3G)
I can't remember can you click on the "cell standby" tab in 2.2 to get additional information? It will usually say something like xx% time without signal.
yes you can click on it but that option is not showing. I was thinking just like I could my Eris was place into airplane mode take it out and it would correct the cell standby issue. But the xx% without signal is not showing. Well at least on mine it doesn't.
I don't think it ever says 3G. Mine goes from 4G to 2g. I just traveled to Indianapolis and pulled 6mb down but at home we don't have 4g yet even though it says 4g. My download at home was the same as my nexus one = 700k
So while I see it drop to 2g... I think they replaced the 3G icon with a straight 4G icon.
Plus I thought utms was edge?

Same here with the cell standby... Battery life isn't that terrible for me though (six hours down to 75 percent). Still this seems to be a big problem. Can we somehow force it to just use 3G for the time being?

I was having the same issue, and battery life was terrible.
Performing a full factory reset as well as completely draining the battery several times solved the issue for me.
Before the factory reset Battery Monitor was reporting heavy battery use even while idle, after the reset it only uses 2-5mA while idle compared to over 150mA before.
Today I went from 5:45 AM to 4:30 PM and am only down to 70% charge left.
same exact issue here. My usage habits have not change from my mytouch 4g which only showed a few percent of cell standy and phone idle. I dont get it, but i think that is what is killing my battery.

I'm glad it worked for you but I am a little confused as to how could this fix this problem?
i haven't been using wifi since i got the one x cause it seems to drain my battery faster then when I'm just connected to cellular data .. what do you guys think .. i've only had the onex 11 days and i already used 2 gigs data with normal usage .. I'm afraid ill be throttled soon when i hit 3 gigs .. i know on my iPhone the wifi used less battery than cellular data
I'd say WiFi probably uses more, but it's hard to tell. It could just be that my phone is having trouble locking into my routers signal.. it goes from full bars to 1 every 5 seconds.

I'm really hoping the ota update will make wifi use less battery than cellular data, does anyone know if past HTC devices r the same when it comes to wifi vs cellular data for battery life? Thanks
Wifi uses less in my experiences. Most of my day is spent in a building where signal is weak which drains my battery. I find if I use Wifi battery life is significantly better.

wifi uses less for me as well
When I'm on wifi all day I can get almost 5 hours screen time browsing. When I'm on HSPA I get about 3 to 3.5 hours. 25% Brightness.

grandfathered Unlimited plans switched over to LTE Unlmtd. have a cap for throtlling of 5GB. 3GB cap is for 3G plans.
thats great to hear that people have been having better screen time with wifi ... i haven't really given wifi the chance to prove to me it can be better ... ill have to experiment .. now if only i had lte!! i wanna feel the sPEEd!! i can't believe i still don't have lte and i live in s.florida!!
Wifi definitely uses less battery than cellular data...not even close.
I just had the coolest thing happen, I woke up and turned my phone on only to find I have lte at my house now! Has this happened to anyone else in the Atlanta area?

Be prepared to get worse battery life than before. LTE really chews battery life alive. I turn off mobile data when I'm not using it just to get better battery though.
im on LTE and get 24 hours easy...and id consider myself at least a moderate user.
I havent noticed bad battery life when I was using it before but its never been constant so I guess Ill find out soon haha
Ottawa - Canada
Where LTE covered pretty much everywhere. I've used LTE on my device and I get at the most 6hours of usage.
I consider myself very heavy user. Download, online music, browsing, IM+ etc... Switching LTE off and going only on 4G I get an extra 12hours worth of juice but the speed is more then what I need 4G speed here is an average of 8mpbs UP and DOWN. That translate to 800K per second in transfer rate. Just as fast as you regular high speed at home. So no there's no need for LTE personally. It just kills your battery off in no time.
I've consistently gotten over 24 hours with light usage on LTE. Obviously reception and level of usage will make a big difference. But for many people the battery life on LTE is plenty good enough to use all day, then charge when you sleep.
LTE destroys battery, but that's what 3g is for

I haven't noticed a significant drain on the battery going from HSPA+ to LTE.
I don't use wifi because of the bugs so i'm always using data.
I easily get 18+ hrs with heavy usage, including 3+ hrs screen time on LTE, so not real sure what you are expecting from the battery. It's a high-end Smartphone, use it for what its meant to be used for.
Based on some of the responses, the logic is like buying a Ferrari and only driving it 55 in the slow lane cuz you're worried about not getting good gas mileage.... Com'on people, use the damn phone!

Yes, I never got a LTE signal at my house which is roughly 50 miles from Atlanta, but recently I've started getting a very good LTE signal at home.
I also don't see any of these battery drain issues everyone talks about. I'm on LTE for about 16 hours a day before I plug my phone in at night, and I always have some juice left. This has changed to be even better recently since I tend to need wifi more using AOKP and it's inconsistent mobile data. But my good battery life was consistent with stock and other Sense ROMs using only LTE.

Lmfao, me too. I'm in hiram. I now have lte all the way from Atlanta to Paulding county. In fact, I have had constant lte since. I was sitting at the bowling alley, which I use to struggle just to get any signal, and I had two bars, lte.
Really haven't noticed much of a difference in battery drain either. Now I do use wifi at the house but still, been pretty impressed actually.

When you get throttled what are typical speeds?? Out of nowhere my speeds went from 16-24mb down and 7-11mb up to about 3-6mb down and 1-2mb up. Checked my usage (unlimited) and i've only used 200+mb so far. Whats up with that?
I suspect that the people complaining about LTE battery drain also have their brightness turned way up, like at full. I know, b/c I'm one of those people. Almost any phone is going to last you an entire day, of even heavy use, if the brightness is down to 10%. Even in the laptop world, the battery life differential going from 10% brightness to 100% screen brightness is double, real world use.
I know 4g is a battery hog, however how would you rate the following with regards to which uses more battery from most to least:
3g, 4g, weak wi-fi, medium strength wi-fi?
I'm guessing
1. 4g
2. weak wi-fi
3. 3g
4. medium wi-fi
I ask because right now I'm waiting on a new usb port for my nexus and in the meantime I am fortunate to have a spare charger, however it takes 3 hours to fully charge so I'm keeping data turned off unless I need it because my samsung galaxy nexus only lasts 2.5 hours w/ heavy use and auto brightness turned on...rooted w/ Sourcery and Lean 43.
Thanks in advance

my personal opinion is that wifi uses the least battery, regardless of 4g or 3g.
4G uses more battery than 3G than wifi
4G>3G>wifi>2G:laugh: wifi is best than 3g and 4g
4G drain more
Thanks.
So regardless of how strong the wifi signal is, using it will eat up less battery than 3g?even when it takes 30 seconds for a Web page to load? I would have thought it would be better to use 3 in cases like that.

just background data tasks, mobile gaming, streaming

2. 3G
3. Weak Wifi
Big Download
1. 3G
2. 4G
3. Weak wifi
Reversed the differential on big download because the difference in 4G speed is very significant and you may very well waste battery on 3G by engaging in extended radio transmissions to and from the tower that 4G would have ended long ago. 3G will use much less at continuous tasks at a fixed/slightly variable(but well within 3G's capability) such as gaming and streaming. Both should be fairly equal at idle aka not tranmitting/receiving data, provided your phone is indeed going to sleep and not transmitting data every 2 seconds. But if you got apps waking it up every n minutes, expect 4G battery drain to go up. The moral, leach wifi where you can and make sure your phone isn't talking about you over the air all day.
Hi guys. My battery life is very good when i dont use my phone. And i dont have mm-qcamera-daemon problem. But when i open wifi or play a game (even when i play flappy bird, not joking) battery drains %1 every 3-4 mins ( just wifi is on, i use greenify), and when i play a game battery drains %1 every 2-3 mins. Is this normal ?
I use stock kernel, i'm on ondemand governor, stock rom. I'm rooted.
Thanks guys.
Sounds normal to me, would make screen on time of 3 to 5 hours. That's not to bad... Compare to SOT of others in other threads...

video games are battery intensive. you can use franco's per app mode app and use that to throttle processor and gpu speeds since most games don't need full power to run
You'd think simple games would always be less battery intensive but that is not the case. I'm not sure if it's lazy programming or just the inherent nature of Java.

battery life is all about how you personally use your device, how you personally set it up, which apps you chose to install, and very much about the quality of your phone/data connection. even if you personally do everything right, if your phone/data connection lacks(quality and speed), then your battery performance wont be too hot.

you would/should do much better on lte as opposed to 2g, unless your signal isnt good. generally the faster data travels back and forth would be better for battery, since the job finishes faster. i get an hour more sot using lte as opposed to 3g(hspa+).

Can't beat wifi if it's available. And turning down those radios on your phone and turning off NFC, GPS, etc is the best way to preserve battery life. I only turn them on if I need them.
