JI6 JI2 JFD difference? - Vibrant Q&A, Help & Troubleshooting

I'm not quite sure what the JXX Modems do.
I tried google and XDA, and someone posted a question and no one replied [maybe cause (s)he sounded like a jerk].
Flashable JI6 Modem (Low battery life, data seems potentially higher in low signal areas)
Flashable JI2 Modem (High battery life, data seems potentially lower in low signal areas)
Flashable JFD Modem (Stock modem file)
[I got this from the Tean Whiskey site]
Can someone enlighten me?

i would also like to know the answer to this please! also, whats the difference between ji6/ji2/jfd/ AND the new jpm?

Real quick overview
Stock is simply the one that came originally on the phone
JI2 has much improved battery life over both stock and JI6, signal strength is supposed to be about the same as stock
JI6 is reported to have much improved signal strength in low signal areas BUT at a cost of battery life. Aka stronger signal but faster battery drain then JI2.
Which one should you use? It depends on whats most important to you. If you need the best signal possible JI6, if you want the best possible battery life JI2.

what about jpm, the new froyo baseband? is that any good compared to the others?

adm1jtg! When you say lower battery life, how much lower in terms of hours?
If the difference is one hour I would rather use JI6 since my privider doesn't deliver a good signal.
Thanks.

So what version is the ota ji6?

Is that a serious question?
How do you think the modems got their names? From the firmware build names that Samsung used.
JI6 modem = JI6 firmware (ota)
JI2 modem = JI2 firmware (leaked)
JFD modem = JFD firmware (stock)

For me personally JI6 was horrible battery life. With a good rom and JI2 I could run 24 plus hours with lightish use. With JI6 I couldn't make it 8 hours same exact config. I also didnt personally notice any difference in data speeds at all and I am in a good signal area so cannot comment on increased signal strength from JI6

The new froyo builds by eugene all use JI6 or JI2

My battery also drains fast with JI6, but I get signal at work and with JI2 I don't, so it's worth it for me. But, I have a charger at work, so it's not really a big deal & I have a couple spare batteries that I can swap when needed.
If battery life is important to you, then I honestly suggest staying away, you can watch your phone and see the battery drop!

Actually the new froyo roms are based on jpm.

adm1jtg, tjhart85
thanks for responding.
I will try to stay with JI6 for now because my provider has a very weak signal in many locations.

Does JI2 has a fix for the GPS issue?

Baseband/Radio/Modem

I flashed Axura 2.1 and the battery life is fantastic. The screen seems to be the only thing draining my Battery life. However the fact that there is nothing else draining my batter except the screen has highlighted that my Signal strength is really low. Stays around 88-93 dBm with 13 asu.
Now i have been checking other android phones and they never go above 86 dBm. This has lead me to question whether it is my Modem/Baseband/radio
or it is just my Vibrants faulty antenna.
Another question is that i came across this thread about reflashing radios. It said that it would be necessary at one point anyway. however, i have flashed two custom ROMs so far and no mention of radio reflashing. Do the roms reflash the radios themselves ?
I am guessing Modem/Baseband/Radio are the same thing. could someone shed light on this ?
roms and radio are not the same! I think its the modem your looking for. Depending on the rom you flash whatever modem they chose to use for that rom then thats what your gonna get. But if you dont like it you can flash a different one.
The Ji6 has much better signal but at a cost of battery life.

[Q] What modem has best signal for you?

Which modem provides best signal? I realize that performance varies by location. Just want to know what works for you.
For me the KA6 and the KB1 Both are about the same except the KB1 has better battery life.
Depending on your ROM it may be a little different on the battery life but for the most part these 2 are the fastest
KB1 ...love it...faster internet network....signal as well...and battery i havent really test it but i have read that on bionix it drains battery fast..
KA6 for me. I hit ~5mb down and ~1.5 up regularly on HSPA. With KB1 I usually only get 3g no H in my apartment.
Ka7 for.signal, but kb1 has.the.best mixture for.me.
Sent from my SGH-T959 using XDA Premium App
KB1 here too.
KB1 is the best for me also. Nothing else is even close.
Im using sweet honey 2.5 with the Overstock 1.4.1 Kernel and the KA6 modem and i have AMAZING battery life.
comparison: i was running bionix 1.3.1 and whatever is stock in the and half way throught the day (6 hr period at work) my battery would be from 100 down to 68 with no use.
I am now running SH 2.5 with what i stated and now my battery is only down to 92 after the same time with no use.
This is going to depend on the area you live in and how the towers are set up. Try them until you find out what works best for you. Modems are quick and easy to flash, and not very invasive on the rest of the OS. Install and make some calls and run some internet speed tests. This will help you find out what will work best for you.

[Q] Best Modem CM7?

JTs distro comes with EB01, I know there's an EC modem and now a new ED modem, thoughts on which is best from a signal and - quite important to me - battery life standpoint?

I found the EC09 modem to be the best for me in terms of overall quality and signal strength. In addition, at one point, I was pulling two days of moderate usage out of a single charge with it. Plus, it *seems* to have the least problems of all the modems I tested and jt said a while back that even he recommends EC09 for cm7.
However, if you don't want that, ED04 is probably the second best.
Edit: Here's a list of all the radios with download links and instructions, in case you need it: http://forum.xda-developers.com/showpost.php?p=12816670&postcount=39

I can tell you the EC09 really is all that it is hyped up to be. Zero problems with it and I was consistently getting 2 days per charge using it. I use my phone quite a lot but everyone has a different perspective on usage.
Some think that a few texts and 1 call a day is moderate while others see it as watching an entire movie + Facebook, twitter, news, weather, angry birds, and 10 calls + live wallpaper as moderate. This is a phone, not a desktop computer...keep that in mind.
Currently I am testing the new ED05 modem. I have not personally seen the increased battery drain but I did have a MMS problem today. Though it may not be the modems fault and it was quickly remedied.
Thanks guys, that sounds positive, I'll flash EC09 when I get home later and then calibrate the battery. I've been getting really poor performance with my current radio, so am looking forward to giving it a shot.
If you find wildly great performance, stability and battery life with ED, post back here, if you don't mind.
Thanks!

[Q] Best Combo for Battery life?

Okay so I've been messing around with roms lately and I'm somewhat a flashaholic lol
But now I'm really looking for something flexible but GOOD on battery life.
What Combo is best for battery life?
such as Modem & Kernal (+ Rom)
I'm currently on this (at the moment):
Rom: MIUI V4 (360 PRODUCTIONS)
Kernel: 3.1.10-subZero-1.6 End_of_Line)) #167
Baseband Version: T959UVKA7
My battery life isn't really too special, I have wifi on, 3G preferred, auto brightness, sound on high. . .
85% - Discharging 2h 5m 30s on Battery
Any ideas on bettery battery life or is this pretty much good/normal?
also my battery isn't a samsung battery its an MYBAT 3.7V LI-ION Battery VLN-08 1200mAH . not too sure if that plays a big role in this.
sidenote: TWS IS ONLY 4%.
Here are tips not ROM/kernel specific http://forum.xda-developers.com/showthread.php?p=20245857

I'm going to make an assumption here, and perhaps it is an incorrect one.
I've installed countless ROM's on my Vibrant, and I've had mine a VERY long time (got mine the week before the official launch...long story).
I've found no roms that match the overall battery life of Samsung 2.2 froyo based roms. It is for this reason that, though I've tinkered with practically every single gingerbread, ics, and jb rom ever released, I always go back to my personal favorite as a daily driver. Project V w/Bali 1.8.8 kernel and KB5 baseband.
My assumption is that the "black box" effect is at play. Getting the last baseband available to us (KB5) to happily play with later builds of android has always been an exercise in frustration. Sure it has been made to "work" with later builds, but given the closed nature of it it's clear it just doesn't work as seamlessly well with anything else.
My battery life with 2.2 based roms has always been way better than later android builds, often lasting twice or more as long.
Thanks for the link I'll take a look at it.
@masterotaku : Everyone says Froyo has the worst battery life ever :\ but I also believe what works for my phone may not work for yours, and I do know Froyo is a very stable rom it was the rom i ended up going back to and sticking with on my MyTouch .

Slim bean with stock kernel getting a full day with moderate usage and one thing I took the Samsung 1650 mah battery but don't know how much difference it makes but happy with slimbean

The best thing I ever did was to buy the Anker 1800mAH battery for my phone. Probably due to the fact that the stock battery is getting up there in age as I'm sure everyone's is. I recommend everyone buy one.

[Q] Worse battery life in JB 4.2.2

Hi, I tried couple JB 4.2.2 ROMs and the phone's battery drains almost 3 times faster than on Froyo. The battery of my bluetooth hands-free was even shorter. I nearly decided to buy a new one. Then I went back to Froyo and now everything is OK. On JB I installed the CPU Spy and Wakelog Detector and there was no problem. I realy want to move to JB, but I don't know how to improve the batteries' life

Is it possible an inappropriate modem be the problem. I'm in Europe and I don't know what is the official modem for my GSM operator.

The kernel is usually the difference maker when it comes to battery life. I have heard claims of certain modems that extend battery life but its usually different for everyone. Most 2.2 ROMS but not all use KB5 modem, you could flash the kb5 jelly bean modem and see if there is a difference.
