[Q] Tips for Skyrocket in Non-LTE Area - AT&T Samsung Galaxy S II Skyrocket SGH-I727

So does anybody use their Skyrocket full-time in a non-LTE area?? I'm back home now for the holidays and don't have LTE here, and my battery literally went from 97% to 37% in 2.5 hrs with 49 mins of screen on and 59 mins of awake time. Meaning no significant wakelocks. Just the radio trying to find LTE. Is the battery always that terrible for you guys in non-LTE? I get a consistent ~18 hrs with 3 hrs screen on time while on LTE 24/7.
What do you guys do?? I tried flashing the Rogers radio and switching the Network Mode, but it does the same thing as on an AT&T radio - switches right back to LTE. I tried selecting the Network Operator but I never get any choices to even select AT&T like others report. *#2263# doesn't work on CM. I tried switching the mode in *#*#4636#*#* but it switched right back to LTE. What gives? (I'm on CM10.)

For a while I was in a non lte area. I had better battery life then than I do now in an lte area. I don't do anything different. I use uclf6 radio, which gets the best signal for me.

Man that's interesting. Every time I come home to PA from Atlanta, my battery just tanks. I can't even make it through half a day. And the only difference is going from constant LTE to no LTE at all. No change in my daily routine. And I've been using UCLF6 since it came out. Now I'm on the Rogers RUXLF3 because I wanted to try switching network modes, which didn't work. I don't know why it works for everyone else.

Sometimes when you move far distances they might have to reset something with the network. When I moved from pa to Florida they did some kind of network reset or something to my old iPhone. Not sure if they still do that or not. Now I travel from Texas to Louisiana and Mississippi a lot and I don't experience any battery tank. And I don't have lte in Louisiana or Mississippi. I get better battery life there then in Houston on lte.
Are you carrier unlocked? Even if you are I don't think cm10 based roms are able to switch network mode. That's if I remember correctly, which I could be wrong since I don't use that feature.

Ohhhh I didn't realize that about CM and the network mode - thanks! I think I'm gonna try out the leak or Jedi and see how things go with that. I'm not carrier unlocked - just straight up AT&T.
That's interesting about the reset for location. I never heard of that. But I bought the phone here in PA, with a PA number. I've just been down in Atlanta for grad school. We're really close with our AT&T sales rep though so I could probably ask her.

Yeah ask the rep, he probably knows more about how the network works. What's weird is, I've not had a battery drain when going to non lte areas and spending weeks there. It actually saves my battery. Here in Houston I hit 40mbps/s and it probably burns through battery 15% faster than non lte areas. I have strong signal in both areas. Usually -75 to -85dBm. So it's not a signal fluctuation issue. Do you have weak hspa signal in pa?

Looks like I'm going from about -90 to -105 dBm. So I guess that's not too great. Unfortunately, I can't tell you what I get in Atlanta.

Yea that could definitely be it. Didn't think about that. But man that just seems like a huge hit in battery life - from 18 hrs down to 4 hrs. And I never had that problem with my Captivate, or my dad's Infuse. That's why the only major variable I could think of was the LTE.

It's always looking for lte, and now it has a crappy hspa signal. I'm guessing that's it, but it could be something else.

I'm on aokp and what I have to do is search for networks manually and select AT&T. Once you do that, you can force the 2g only option. Or *#*#4636#*#* and select the network mode you want. I'm on Rogers radio on AT&T and my phone isn't unlocked.
It can take like 2 minutes to search when you first do it manually.

As I stated in the OP I tried both of those things and neither worked. I'm on Rogers radio on AT&T and not unlocked. I tried searching for Network Operator but all it does is flash a popup saying Searching and immediately disappears. I've clicked it a million times. Sometimes it takes slightly longer, but still never gives any results.
And then *#*#4636#*#* just switches the mode back immediately after I change it.

That's strange, I've only used my phone on at&t. Never unlocked it. It works fine for me.

Crappy Battery life, try this!

So I had just gotten done posting a smartass remark about how I had gotten two days on one charge with my phone, only to pull it off the charger go to work, and have the sucker die in 4 hours.
I figured out what I did, and you should try it too, it may help you out. I am running the leaked radio btw.
So earlier today I decided to go into ##778# and type the password 000000 and then modem settings and rev A and change it from Enable to eHRPD because I figured with the 4G network back I could use the dual radio 3G network. Well That is when my battery life went to ****. I pulled my phone out of my pocket to it burning hot and at 9%. I quickly changed it back to Enabled, and it survived the 9% all the way to 5% over a period of another 6 hours.
So unless you need to talk and use data at the same time, use the regular 3G network like I am, and see if your battery life doesn't improve. I still am on 4G all day, but this was literally the only feature I changed on my phone between amazing battery life and crappy battery life.
You can still do talk/data at the same time on Rev A with 3G.

Right and at the moment, no thunderbolt should have eHRPD. No matter what verizon says. So we're all running on rev a right now, and you must have done something else. EHRPD will not waste your battery any more than normal.

Actually mine is set to eHRPD. Just bought it from Vzw a few days ago, rooted and flashed DBamf 161 along with the new radio and Im still set to it.
Making me think I should switch it hmmm.... hmmmmm

I just checked mine and it was set to eHRPD by default. Does this mean I should change it to enabled or leave it alone?
It doesn't really matter what it's set to. It seems as though Verizon has made all Thunderbolts default to Rev A in 3G areas after the outage rather than eHRPD regardless of what the modem setting is. You can check under About Phone-Network-Mobile Network Type
I use the LTE on/off app and Juice Defender Beta to increase battery life.
Set my phone to eHRPD then rebooted it and it went back to enabled I think Verizon is doing a tower by tower fix.

Mine is rooted and I get almost 2 days of moderate use out of it. Its the only way to make this phone truly great.

what kernel/governer do you use?
I'm running das bamf 1.6 remix with the stock radio and the kernel it came with. I know that it isn't really necessary to wipe but I did. I used a battery calibration app and auto brightness.

What are you guys using?
sent from my B.A.M.F Thunderbolt
I'm currently using Tesla Coil 1.7.1 with imoseyon's batt saver kernel, setCPU using the smartass governor.
Today my battery life was absolutely horrible: 6 hours from 100% to 19% with 1 hour of screen on time at ~25% brightness, 8 mins of call time and maybe 2 hours of music off of my SD card.
I just can't figure this phone out...
I have noticed that as well. Some days my battery rocks, and some days it sinks like a rock. Not sure why. It's as unpredictable as my wife! LOL
sent from my B.A.M.F Thunderbolt
The other thing I do is if I know I am not going to use my 3G or 4G connection I turn it off until I need it. This Rom I use has a widget for switching it on or off.
sent from my B.A.M.F Thunderbolt
The battery sipper kernel is the only kernel for me. Using the same Rom I went from about 6 hours of constant 4g to over a day of 4g. I do have the extended battery. I leave 4g on ALL day and get more battery life than I did on any other phone. I love that Damn kernel.

So does changing the modem do anything or not? I just checked and my Rev A setting is eHRPD and under about phone, it says CDMA-eHRPD. I have not changed anything other than turn LTE off when not needed, and when I turn it off I select CDMA auto (PRL). I am using the new radio and BAMF 1.6. I get decent battery life so I am not too concerned, but I am curious.

4G down in phoenix for fourth time

About twice a month, it seems like 4g data goes down in phoenix. Anyone experiencing this? I change to LTE mode in dad bamf settings and get nothing.
Sent from my ADR6400L using XDA App
Negative, I work in PHX live in Gilbert... it's never gone down for me... I have had the phone occasionally lock itself in 3G when I know I'm in a 4G zone, but a reboot or LTE on/off usually fixes that.
Mine was out last night but thought it was mostly due to storm, back up again as I am using it now. Queen Creek is my location.

Thanks guys, I am guessing it is a radio issue. Will try reseting.

i have lost my 4G service in Phoenix before but then i switch set dns to the google dns option and it works.
Other than sporadic issues lasting a few minutes, have not had any outages in the past few months. Out in the Queen Creek area.

How'd you like that storm? I live in the outskirts of Queen Creek where the microburst hit. Kinda weird seeing twenty powerlines turned into splinters, looks like something snapped them at the base like twigs.

no 4G in my area yet, although since yesterday the 3G has been going up & down regularly and is still doing it today. a friend of mine has a Droid Charge and has said the same thing is happening with her phone.
the "3G" logo will suddenly disappear & the bars will go off, then it'll either come right back up(or after a few seconds) and sometimes will show "1X".
i'm in Carlsbad, CA btw. i wonder what the hell Verizon is doing....
Mine cut out for a minute or so but nothing major.
i live in the tempe/scottsdale area and have never gotten 4g outages
Works for me as well. Scottsdale/Phoenix border.
Its been intermittent for a day or two in Dallas/Fort Worth when ever they do the network upgrade nationwide for the new networks to come online.

Is there anyway to turn off lte?

I am using the the latest sky pics, is there anyway to turn on/off the lte/3g
Thanks

Not aware of anyway to switch to 3G only, but I know gingerbread has an option for hspa/GSM and GSM only mode. I just use a different apn to access atts hspa+ only network, gets me around throttling. Running sky ics ucle2

Use seans sky ics rom, incredible battery life. TIP: Some dont know this, but if you go into wifi where it shows what access points are in reach, hit menu and an advanced menu will pop up. Tell wifi to only stay on while charging.
If i am on wifi and pocket the phone, wifi will turn off while sleeping, it will still use cell data though, but saves battery big time while sleeping. I have had the skyrocket for a few months now and I am pretty normal to heavy user and I can easily get a whole day. 16 hours+ with data on at all times.
The sky ICS rom does allow you to tuen data off completley within the 15 toggle mod that is baked into the rom.
Yeah that's the rom I'm using, but I was just wondering if I can have data on but lte and 3g off, thanks for trying to help anyways

Tests have shown that the LTE radio is on even if using a different APN or 3G Only mode (Rogers GB)

Is this normal? (New to at&t after many years)

Ive been on verizon for years and made the switch over to at&t to get the one x and have to say Im loving it. At&t has really made big improvements to there network as far as everywhere around my area goes.
Here is whats going on though:
Every now and then I can pull my phone out and turn the screen on to see it show full bars E then 5 seconds later it will change to full bars G then another 5 or so seconds full bars 4G. Its not a big deal but just wondering is it normal?
Another thing Ive noticed is when I leave my driveway of my house and get out of range of my wifi it will go to no service then to 4g. Its fairly quick but I dont remember it with any other phone Ive owned.
Could be signal issues with your towers or a sim card issue .

Its not the service its the phone. It takes a while to realize the data connection has changed and therefore updates it slowly. You should be fine its just annoying as hell if you are watching it all the time.

Yeh its more of a mental thing than anything. It hasnt every caused me problems as actually using the phone but watching it cycle through E-G-then 4G a few times every day is starting to get to me. Ive tried all the radios also and Im currently on 1.88 as it seems to have the best speeds. Maybe I should try a new sim.

Did you ever get it resolved?
While this does sound like a bug could it also be a power saving feature designed to put the phone in the lowest power state when there has been a long rest in data or another source, WiFi, is available?
It went away with the vivid when lte went active...

I was having similar issues until I upgraded to the 1.88 RUU. Now I'm running CM9 with no data issues. I think it is the phone or rather the software. Data would stay on E but there was no signal. Had to reboot the doggone phone ever so often just to connect to data.

[Q] Poor reception/data quality on CM10.1.2 despite radio upgrade

Firmware: CM10.1.2
Recovery: CWM
Notes: Full wipe, cache partition, dalvik cache, erased SD card, etc. Closest thing to a clean slate as possible before flashing.
I flashed CM10.1.2 and then GAPPS and then the new skyrocket radio because I was unable to hold a connection for more than 2 seconds before calls dropped. It was essentially unusable until I upgraded the radio. I don't seem to be missing calls but the poor reception is hurting my battery and the data speeds are very slow. Last I checked, I was without a signal 40% of the time whereas before it was close to 0.
Right now, it pretty much always stays on 4G and 0 bars. Occassionally 1 and then briefly at 2 bars inside and outside. However, whenever I get a call, it immediately switches to H+/3G and then I have full bars. So I'm not really sure what's happening. I also seem to be receiving texts on time without lag.
I've gone in and chosen a network - there are three options for ATT in my area and choosing any one of them doesn't make a difference.
Is there something I'm doing wrong? Any suggestions?
That's what's supposed to happen

That depends on your area and the radio used. I was talking about the switch to 3g when making a call.

Ahh, okay.
I am using the ATT official JB radio. Before I upgraded the radio and the firmware, I had pretty good reception when I was CM10.0 so that's why I'm confused about the reception problems now.
Have you tried the latest Rogers radio?
