LTE battery life ??

Nope. That is either unrelated to LTE or an iPhone issue. The last few generations of Android devices have not experienced any significant battery drain due to LTE.

On iOS 6, If you go into Settings | General | Usage, it will show you the times since last full charge for Usage and Standby.  You could use this to compare and know for sure.

 

I'm very happy with my iPhone's battery life on LTE.  But I'm in Houston so the coverage is pretty good here.

 

If you are not in an LTE area, go to Settings | General | Cellular to turn off LTE.  I usually turn off LTE when going to the family farm to keep my iPhone 5 from searching for it in order to get better battery life.

It is funny you bring this up, because I was just thinking about this the other day. My phone gets amazing battery life when its connected to an LTE signal.

Same here, when connected to LTE, my battery last longer than 3G. I think it probably has to do with the difference in speed, especially when all my accounts are syncing, it syncs faster over LTE, rather then just hang there trying to download slowly over 3G.

It might affect your battery life at first. The weaker the signal you are connected to, the more power your phone uses (and thus, the faster the battery drains). If you're constantly connected to extremely weak and distant LTE sites, it might cause extra battery drain. However, that's going to be rare, and there are so many other things that could affect your battery life that I doubt you could pair it down. I say leave it on.

Turning off LTE when you do not have any LTE service in your area will not help your battery life at all. The LTE and 3G radios use the same chip, so there is no power savings by disabling LTE on the iPhone. Like WiWavelength stated this did not used to be the case with older Android phones, but now all recent phones use one chip for 3G and LTE.

 

That being said, if you do have LTE but very poor service turning off LTE can help boost battery life as your phone is not trying to connect to the poor LTE signal but instead a closer 3G signal.

 

Anandtech did a battery life test of the iPhone on LTE and 3G and found the iPhone battery life just about doubles when LTE service is available in the area:

I know while I'm in an no LTE coverage area if I have LTE enabled it smokes my battery life cause its constantly searching for it. Does it get better on battery when u have a steady LTE signal and isn't searching anymore?

 

In addition to what others have said, just because LTE is enabled doesn't mean your phone is constantly searching for it. It only runs occasional scans, with minimal impact on battery life. You either have a weak signal, or something else is wrong.

I can definitely say that what has a much bigger impact on my battery life is the speed and signal strength of my data connection. When I'm in ATL (where there is generally very plentiful LTE), I tend to get great battery life that easily smokes my 3G battery life. My GS3 doesn't really seem to lose anything from being left in CDMA/LTE mode and definitely isn't scanning that often to begin with.

yea well my thunderbolt lte gets crappy battery life when on lte... /sarcasm

 

which is where this claim that lte gives and batteries dont mix well came from... once upon a time that was the case but not so much now like AJ said

The real issue was that a hodgepodge of 65 nm process chipsets, battery, and big screen did not mix well.  As airlinks, WiMAX and LTE had relatively little to do with the issue.  Thankfully, with chipset consolidation and 28 nm process, the problem has been largely solved.

Historically, my phone has done better for battery life in an LTE area than an EVDO area. But my phone doesn't constantly scan for LTE and kill my battery life, my phone scans for a better EVDO signal to attach to, but never finds it when needed because there is too much to interfere in between me and the local Sprint site to get a better signal.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
