Do different modems affect battery life? - Samsung Epic 4G Touch

My question is do different modems affect our battery life differently or not really?

Yes they do from my experience. They also effect your signal strength.

I'm aware what a modem is and that it affects signal and strength lol. Just wanted to know if they have effect on battery life. Thanks for the response!

Signal strength directly affects battery life, so that'll be a yes.

I flashed my modem back to EG30 a couple days ago because before ever experimenting, I got the best data speeds on EG30 Modem. So far it has been the same way since I've flashed back to it. I've been getting good signal strength majority of where I go. But my battery drains a little faster than it did on EK02. EL29 Modem also gave me unacceptable drainage.

Im currently experimenting with all modems on Blazer ROM 3.9 Im not done testing at the moment but If I had to pick the best modem w/ respect to battery life right now it would be the EL13. Im in Chicago BTW

EL13 always gave me good signal. But my data speeds took major slow down hit. I might test it though. I am also running Blazer Rom v3.9

Better signal for me...getting around 16mbps down in SoCal but battery seems worse for me. Might Odin back cause I get 15mbps with the old modem but get awesome battery life.
speeds are up, batterys down.calibrated last night will see how it goes next week.
I'm getting way better signal than what I was before.

for me i think the signal is either the same or slightly worse, and the battery seems about the same so far, no significant difference.

Been using the new modem for the last two days thanks to team kang.
My download speeds havent improved. What has improved is the ping. on the old modem i was getting 860ms for ping but now its only 43ms. much better. I live in a major city and didnt expect the modem to improve the dl speeds.

For me. Signal is about the same and battery life sucks. I'm about 2 hours off the charger and I'm at 51%. I cleared bat stats through cwm after fully charging and waited till 100% again after reboot before unplugging. This is my 3rd cycle after changing to Whitehawk's KL1 and updating the baseband.

Which modem and kernel are you using?

I was hoping to get some feedback babout which people think are best for battery life,signal strength, GPS, etc. I was hooked on EL13 modem then gave EL26 a try and it seemed to improve my 4g a bit. Then I went to EL29 and speed seemed great but battery was meh...however now it seems to be settling in nicely. Also, any thoughts about lockscreen mod and toggle mod using more battery?

EL29/EL29
So far battery life I've not had much of a problem and signal for me atleast has been great. Put EL29 in while I was in Mi over the xmas break and noticed that the signal I got while I was there was actually a little better.
As for the lock/toggle mods After redoing my phone to a new rom I've not reinstalled them and pretty much kept things stock. Didn't really notice any issues with widgetlocker when I was using it though.
I'm using EL26 modem and kernel with unnamed rom. Here is my personal experience with the different kernel/modem combos:
EL13 - best battery life, decent data speeds, least smooth of he three, very stable
EL26 - avg battery life, fastest data speeds, smoother than EL13, avg stability (some lockups, camera sometimes doesn't work, etc)
EL29 - worst battery life, avg data speeds, but most consistent, very stable, GPS sleep issue (this is the only kernel I experienced GPS lock issues with)
Given the battery drain and GPS issues, i'm disappointed that EL29 is going to be he official Ota update. I hope someone tweaks the kernel for better battery life

EL13 on Calkulin's latest 2.8.1.. everything else untouched.
I've tried ek02 modem for a while and EL29 recently. Because I've mostly used 3g, ek02 modem gives me slightly less signal but substantially faster data speeds. EL29 is better signal but slower speeds. My favorite kernel is desperado 1.3 ek02. The test setup I'm running now is stock odex el29, rogue stock el29 kernel and ek02 modem with hotspot mod. The performance of this setup is good so far and battery is holding up well. I've been running this for 24 hours now. I don't have the discipline and the attention span to test every modem ATM. I also 0'd out the multimedia proxies and ports and set the 4g retries to 15 seconds and -110DB receive, which made a huge improvement in that area.
EL13 Modem & Kernal with unNamed rom has been the best setup so far for me. Great battery life and everything works
I think the EL26/29 kernels and modems have poor battery life. EL29 modem gives me best coverage, but the battery life sacrifice is annoying.
Currently I'm running EL26 modem, Desperado kernel, and Calk's 2.8.1 ROM
See there's 2 sets of toggle mods. Gtg's has the 4g toggle and only a,couple of others like flashlight and 2.7 has no CRT. The AIO toggles has more to customize plus the lockscreen mod. Calkulin's 2.7 with Minimal Black with gtg's toggles seemed solid (all EL26) almost as good as my strongsteve all EL13 setup. I am worried that the toggle customization and lockscreen options are taxing my battery but I have zero proof...its just a theory because more functions are running..hmmmm....decisions

I'm on Unnamed Rom, EL29 kernel and EL29 modem, with moderate use today i had a little over 12 hrs and i still had 52% battery.
maybe not the best but way better than some combos i've tried
I will have to concur
i am using EL26 / modem /Kernal on caluk 2.7
average battery 12 hours but fast 3g speed and rom
change to EL13 kernal /modem
17 hours but half the 3g speed and slower rom
so i am sticking with EL26/modem/kernal for now
Stock rooted
for now..

Calk's 2.8.1 EL29 all the way sofar for me has been a great setup. I consider myself a abuser so 10hrs with about 5hrs screen on time. I feel is purty good also strong data.
OH hey SAINT btw. HAPPY B DAY now go get yo party pants on.
EL13 modem has the best data for me. I did speed test with all the modems and EL13 & EL29 were at the top, with EL13 a little faster. EL29 kernel.

Best answer you're gonna get.
ya man. I have great signal and everything on el29 some people have bad battery life on it. although I dont. but then others may have great everything including battery with el13 or ek02. when I run a new modem I make sure everything is the same version. but you dont have to. they can all be swapped and such. I just do it because I am anal about it. lol
You can't go wrong with EL29.
I have ran ek02 and el29 and I did not see any difference

I worried about some ppl claiming bad batt on EL29, but for me it improved everything. Signal and batt. ~shrug~
Sent from my calculator watch.
I tried EK02, then EL13, then EL26 and EL29, for me EL29 gets best data speeds, but never had any issues with signal on any of the modems..
I have also gotten the best data speeds on EL29.

What's your modem?

I'm just curious to know what modem do you run on your E4GT? To this date i run EL29, because i get the best DL/UP speed on average.
Been running the fc18 and it seems to work great. Only problems I have experienced are because things with ics are still in beta. I ran el29 up until I recently flashed fc18. I also had great up/dn with el29. Haven't speed tested fc18 yet...

FC18 currently on xplod SE ROM. Works good.
Also, fc18 on the Goodness v2.5. Seems best so far but it varies by phone/location

FC18 modem currently, fracking fantastic gps locks, in fact first time since I've owned that this phone has consistently locked throughout a whole day. In seconds. Every time. 6+ out of 6+ satellites.
Tentative opinion obviously. Tomorrow is a new day. ;-) but it seems like they got something right in this build, on the agps end anyway.
but 4G data seems not as strong as signal as FC15 perhaps. 3G works as expected.
Currently on Calkulins EL29.

EK02 saved my phone.
I was getting tired of GPS issues (among other issues) w/ a few other modems, but the combo of ek02 modem and kernel works wonders on my phone.
The battery life on fb 27's immaculate! Can't stay away now if I could get the speed of el29 I'd be perfect!
Tried all the modems and I think the EL29 works the best for me too.

[Q] which modem is the most battery friendly up to date ?

I was wondering which modem is the best when you want to extend your battery life.......... Thanks in advance
It will vary by phone and region but for me, EL29 has always been the best on both GB and ICS. You'll get different opinions though and in the end, choose what works best for you by trying more than one.
Sent from my SPH-D710 using xda premium
Im using El29 right now as well. I would say stay away from any ICS leaked modems, and run the latest stock modem (EL29).
i just been flashing modems but i haven't see any difference except battery drain

2 days should be enough but battery drain isn't mainly due to a modem. Look for better battery stats here on xda and after you install it you should see what could be causing the drain.
Sent from my SPH-D710 using xda premium
You do not need to"settle in a modem". Just update PRL/PROF.
Done..
I also concur W/EAO. EL29 sofar for me has been the best. All other ICS leaked modems are crap..
EL29 really probably did have the best battery life but I just couldn't stand the LoS. Where I am signal os spotty so I had to flash new modems for signal upgrades.
Sent from my iPhone killer.
For me FC18 was my favorite and the fastest, but that leak made my battery drain fast. I'm on FE16 now, and it's just a tad bit slower than FC18 but still faster than EL29 and the battery life is amazing.

You obviously didn't try FC18 or FE16 because you wouldn't be saying that if you did.
I flashed the EL29 and it's been better than the otrhers so far.......
