How is jvk compared to jpg battery wise?
[Captivate Android Development] shoman94:
IMO its the same..... JS1, JPG and JVK all had the same battery usage for me.
[Captivate Android Development] brendanmurphy:
JQ1 will not work on my phone. Did the steps nessecary but can't get it to work at all. Will only connect to gsm 1900 which is no good lol because Telus is a Hspa only carrier. Maybe jq1 just doesn't work with Telus.
[Captivate Android Development] lbbo2002:
Yes I enable 850 only on JK4 reboot...flash next one (only KP1 works), check 850 is still good then flash the final and validate 850, reset to all WCDMA bands w/auto, reboot.

Most of the time I have not had issues following the flash orders and having it work. This came as a surprised to me is all.
[Captivate Android Development] geokilla:
Are you sure you did it right? I was able to get it working after two tries. Usually get it working on the first try though.

I still can't get it to auto switch to GSM850 in my basement which has craptastic service if it's in WCDMA850. I wonder if doing the flashing trick with GSM850 and WCDMA850 enabled would work.... I already have the priority set so it'd prefer GSM > UMTS.
[Captivate Android Development] Nucleartx:
I just left my setup as gsm850/1900 and wcdma 850/1900, if I go to auto, it doesn't seem to want to shift over to 850 very often on my device.
[Captivate Android Development] johnsonxray:
hey shoman seems like u spent quite some time on those modems..mind rank accordingly the modems in term of battery saving?

which is your top pick? JPG?

1.

2.

3.

goes on
[Captivate Android Development] garringm:
Flash back to jk4 or jl2 modem,

enable only 850 band,

double check that you are actually utilizing the 850 band by *#0011#,

flash the kp1 modem,

again verify that you are on 850 band,

now try flashing the jq1 modem,

you may try wiping dalvik on the final flash. not real sure how this helps but for some it seems to
[Captivate Android Development] garringm:
FWIW from me

JPG - Also seems to have the best low signal quality

JQ1

JVK

JL2
[Captivate Android Development] shoman94:
Well it's a tough call as they are really close. Battery only....

1. JS1

2. JVK,JPG,JQ1

3.JL2

There are some others but I can't form an opinion because I didn't spend enough time on them for battery life.
[Captivate Android Development] Oxicottin:
what modem is the best for low sWgnal areas? At my house i get full bars but when i go to my gf house i am at no service but she has two bars using HTC vibrant and is able to call and txt. I am currently using the jl2 and have tried the jl3 with same results. Thoughts?

Sent from my SAMSUNG-SGH-I897
[Captivate Android Development] shoman94:
My best is jvk. But you need to flash per my sig.

Is she with a different provider?
[Captivate Android Development] johnsonxray:
JS1? are you sure? im actually looking for modem that gives 1% loss over 7 or 8hours overnight..is there any? GPS or signal doesnt really matter to me lol
[Captivate Android Development] grkmaster:
I tried JPF last night and battery drainage. 5 hours and like 16% drop.. The night before on JQ1 in the same time frame i lost about 6-7% (about 1.xx% a hour. not so bad) Going to try JVK again today to see.

I remember the other day on JVE that I had the highest data speeds ive seen on any modem and thats when i changed the server from New York, NY to one of the NJ servers and got as high as 4.31 on dl and 1.41 on UL .. i cant get anywhere close to that now
[Captivate Android Development] MaxRabbit:
I can't get JVK to connect to WCDMA1900... Even if I enable only WCDMA1900, it strangely still stays connected to WCDMA850. Help?

Edit: NVM, Reboot fixed it. Stupid moody modems XP
[Captivate Android Development] caanda45:
Well shoman you made me change modems again and i really like jvk, seems to give me a slightly better call volume than JS1. My Bluetooth in car likes it also...($hit I do not want to jinx it...lol) As far as data i haven`t really tested it as I just don`t care, it is what it is. Call quality and reception and bt are my goals and you have found us a winner!!!!

I take your word and great testing!!! Thanks!!!!!!!

[Captivate Android Development] Copacaba:
Just flashed JVK cause i was not really happy with the battery life of JVE (Darkys Rom).

At work atm i have one bar more then with JVE. Will test battery over night and will see how it is at my BF's home as i used to have low coverage over there.

//Edit

Seems like i will install another modem... i have heavy issues with JVK. Data network will work for 1-2min and then just stops working. I have to disable and re-enable it, then it will work for another 1-2min.... anyone had such issues?
[Captivate Android Development] geokilla:
I love how people don't even bother reading the previous 10 posts or so before asking questions. We should just stop answering them!

WiFi or data plan? Because I have trouble with anything associated to WiFi on JVK. I have to disable and enable WiFi twice in order to get the WiFi turned on.
[Captivate Android Development] eliminat:
I haven't had issues with WiFi on JVK. Just as a reminder, when you flashed the new modem did you remember to wipe the dalvik cache?
[Captivate Android Development] ccdoggy:
I am having a similar problem, same modem. before you try and turn the wifi on go into wifi settings (as if you were going to turn it on in the settings) then enable it from the pull down menu?

Does it report "Unable to scan networks"?
[Captivate Android Development] shoman94:
Yea I'm sure... I'm having just over 1%/hr loss sleeping with data enabled.

Good luck... I din't really test JPF too much. The voice quality bothered me too much and it would switch to EDGE to easily.

Thank you and I hope it works out for you.

Interesting... let me know how it works out.

I would reflash.... maybe start over from JL2...

Not sure why a couple here are having issues with wifi. Works like it should for me. to the people having wifi issues... what security is being used? You should be using WPA2 because WEP has issues.
[Captivate Android Development] H3llstorm:
Tried JVK again. Still getting better call quality on JS1.
[Captivate Android Development] shoman94:
Yes I agree that JS1 does have just a touch better call quality as I mentioned before but only in my car at 75mph. IMO thats the advantage to JS1 but JVK have better service and faster data. So for the minimal difference in call quality in certain instances, I will be sticking to JVK for now until something better comes along.
[Captivate Android Development] caanda45:
Correction and sorry I mis quoted myself, I went from JS1 to JQ1 and then to JVK and the sound quality is indeed better on JS1 vs JVK but the BT issue for me seems to be better(or no issues so far is really what I mean) on JVK.......
[Captivate Android Development] shoman94:
Well you had stated call volume not quality.
[Captivate Android Development] geokilla:
You mean WEP is a joke as it can easily be cracked. But yes, I'm using WPA2. But WiFi security is not related to the problem I'm having.

@ccdoggy. I believe so. I don't remember. I just Wiped Davlik Cache so let's see if that fix things.
[Captivate Android Development] shoman94:
I never wipe Davlik when flashing a modem....

interested in the results to that.
[Captivate Android Development] caanda45:
Yup you are right quality in all of them are very good, it is the volume that I find to be slightly different!!! Good catch!!
[Captivate Android Development] ccdoggy:
I just did the davlik wipe a few hours ago and have yet to have the problem again. though not like it happened every single time so its hard to tell. will report back tomorrow about how its going.
[Captivate Android Development] Copacaba:
Uhm,... talking to me there?

Nope, Wifi is lovely. After some more tests it seems like JVK has Problems in low coverage areas for me. One or two bars and the data network (data plan that is) is slow or unavailable. Thats in a closed room here. Outside and in the city i have full bars, had no issues there.

Oh and yes, i did wipe the Dalvik Cache.
[Captivate Android Development] disellusional:
i had problems before and after dalvik cache wipe
[Captivate Android Development] MaxRabbit:
I loved JPG but, after all the good things said about it, I tried JS1. Not a big fan at all, so I moved to JVK. It's my new favorite! All the good things being said about it are 100% accurate.

My list:

1. JVK

2. JPG

3. JS1
[Captivate Android Development] shoman94:
Jpg and jpg? lol
[Captivate Android Development] MaxRabbit:
I dunno what you're talking about-it said JS1 the entire time ;) ;) hahaha
[Captivate Android Development] shoman94:
LOL... I think we have the same taste in modems!
[Captivate Android Development] harpo1:
Shoman you might want to change your reference of SZJPG to ZSJPG. Might confuss some who don't know better.
[Captivate Android Development] rajendra82:
I was all set on ZNKP1 until it disconnected from the towers on me a few times. Looks like they all behave about the same, so I am now going to stay with JVK. It seems less finicky and more efficient at everything, and I know it's not perfect, but having HSUPA is worth an occasional glitch here and there. Plus it's the latest, and that counts for something in my book. I also seem to log on to known WiFi access points a lot quicker when on JVK, but that might be a placebo effect.
[Captivate Android Development] shoman94:
Cool..... until the next one....lol
[Captivate Android Development] devoured321:
Quick question...I've tried the 850 trick...not sure if I'm doing it wrong or if in just not in 850... But everytime I try I have no service at all...i select automatic I get service on 1900.....but never on 850... Am I just in an area with no 850
[Captivate Android Development] shoman94:
That could very well be. You're following it to the T? With JL2 did you get 850 when 850 was selected?
[Captivate Android Development] grkmaster:
So as I went to sleep and woke up - 3 hours and 15 minutes about - I went from 77% to 73% .. not so bad (JQ1) I come to work not even two hours later im down to 53 percent... I hate this place for service - Two minutes ago i checked and it was on 850 and the RSCP was up and down b/w mid 90s to 115.. now I check and it switched over to 1900 and it stead at -94/-95 ... but all the time no matter what it is why do i see it go -255 ??
[Captivate Android Development] shoman94:
Usually when you see -255 is when it switches towers or the data side is reset. It's normal to see that.

Not sure about your battery life.... usually looking at your battery history in Spare Parts it will lead you to what is causing it.... most of the time when I have a battery drain issue, it's caused by the dialer and a reboot fixes it.
[Captivate Android Development] grkmaster:
Well its weird. idle at home i was fine. From going to work and leaving my phone on my desk and looking at it a couple times it went down to 53. No real use other than looking at email or writing a quick text message. I don't think anything is draining it.

I know JVK sucked at idle, I cant get JS1 to work. JPG was decent on idle but not great. JVE had the great speeds but thats about it. JQ1 seems great. I wish i can try JS1 tho.. I am puzzled to why it wont work
[Captivate Android Development] shoman94:
I almost don't think its modem related... What rom are you on? I say that cause I have great battery life with all those modems...
[Captivate Android Development] grkmaster:
CONTINUUM!! with ONIX 2.0.3
[Captivate Android Development] shoman94:
What have you done for tweaks in cwm and do you have an app killer have you done any changes or customize the rom in any way? I'm sitting here with -108db and am only losing 1% an hour.....
[Captivate Android Development] grkmaster:
no OC just UV.. and no app killer - i just use samsungs built in

100mhz - 100

200mhz -125

400mhz- 125

600mhz- 100

800mhz- 75

900mhz-125

1000mhz- 75

and I got the 4 first tweaks enabled and fast mount
[Captivate Android Development] shoman94:
I have the cpu threshold disabled... for better battery life. I'm oc'd to 1200

100mhz-100

200mhz-100

400mhz-100

600mhz-75

800mhz-75

1000mhz-50

1200mhz-50

still messin with the under volt
[Captivate Android Development] grkmaster:
Ill disable the cpu threshold.. i thought it was recommended to have it enabled
[Captivate Android Development] shoman94:
Yes for more speed... better battery disabled...

It ramps up the cpu quicker and holds it longer.... hence why it would use more battery.
[Captivate Android Development] LNJ:
But if you use it in conjunction with the CPU frequencey script, it kind of evens out so it's 50/50
[Captivate Android Development] shoman94:
Did existz talk about that? I don't remember seeing that....
[Captivate Android Development] grkmaster:
I will test that out and report back - but you say my issue is not modem related. Yesterday before i turned on wifi in here at work, noticed the battery draining fast ,i turned on wifi and the battery wasnt dropping at that fast rate
[Captivate Android Development] shoman94:
lol... it is usually the opposite.... wifi uses more power at idle. Something is weird... look through the battery history in the spare parts app.
[Captivate Android Development] grkmaster:
Once i charge it up, and unplug it and ill turn wifi on for a hour and then for a hour with no wifi

edit:

quick question - for text messeging what app are you using? could be a issue ill assume (im using chomp)
[Captivate Android Development] shoman94:
oh yea... cause chomp uses data I believe....

Also. typically I would test battery once you get to 90 and start there because 100 to 90 is usually quicker than the rest of the way.

The only data I have at idle is Gmail setup as PUSH.
[Captivate Android Development] LNJ:
The script is a battery saver script that adjust the cpu frequency.

But it made it a little sluggish for me.

So I removed it.
[Captivate Android Development] grkmaster:
im not sure if it does cause i dont use the textfreak crap that it added ... and ill do it now since im around 95 percent

edit: btw i installed this -- maybe this can help a bit.. if im not mistaken you said you have some auto airplane mode on boot or something like that -- http://xdaforums.com/showthread.php?t=938677
[Captivate Android Development] timn2bama:
What is edge frequency? 850? Can I force it to stay on edge while out in the country? Lol
[Captivate Android Development] harpo1:
settings/wireless and network/mobile networks and swith the network mode from auto mode to GSM only. This will keep you on edge.
[Captivate Android Development] shoman94:
Edge works off 850 and 1900 just like wcdma
[Captivate Android Development] psloan:
I have been desperately trying to get jq1 or jkv to work for me. I get them both to load the 850 band fine. I also get them back to auto and using both 850 and 1900 bands. They both seem to have great battery when using wifi (about 1% an hour) at work and at home. jq1 seems better for me on 3g though(about 2-3% an hour). But both of them seem to have this mean streak on the battery. At some point they both start using more 10% battery drain an hour. I have tried re flashing/delvik cache clearing etc. but both those modems return to that same behavior at sometime durring the day. I cant seem to pinpoint why. I can run jl2 just fine. wifi ~1% draw. 3g ~2-4% draw.

Reason i am trying jkv and jql is for better reception and 3g battery use. otherwise the jl2 would rock.

I am running Andromeda 1.2 with Onix kernel undervolted.
[Captivate Android Development] grkmaster:
So about 40 minutes ive lost only 1 % (no wifi) and i havent touched it at all other than turning on the screen real quick(no unlock). the CPU threshold would automatically adjust as i turned the screen on or as i unlocked it to the home screen?
[Captivate Android Development] white00gt:
How long has it been since you flashed the modem and checked your battery drain?

For me I noticed after I flashed JQ1 my battery drained real quick but after a few charge cycles it improved drastically- now my battery is great stayed at 50% battery level for almost 24 hours with medium texting and calls
[Captivate Android Development] timn2bama:
Thanks for the info!
[Captivate Android Development] psloan:
I have given both modems about a day half trial ( 2 or 3 times each). I use Battery Snap app to log and graph my battery stats. it is really odd to see my battery go along smooth then just dive! See the attached for a graph. notice the steep drops at 16:00 then 22:00
[Captivate Android Development] shoman94:
Is the phone sitting in the same spot all day? I should try that app out....
[Captivate Android Development] psloan:
unfortunately no. I am not able to isolate the location. but I was moving one of the dives for sure. Started in downtown and keep going while I was on on the train home. when I got off the train it was still going down all the way home. did not stop until I had flashed jl2 . I have just started using trillian. I might just stop using that for a day or 2 and retry jq1. See if that the culprit.
[Captivate Android Development] devoured321:
Yes had not luck at all...might have to try in different area
[Captivate Android Development] shoman94:
Well if you didn't get 850 with jl2 you're not gonna get it with any other.
[Captivate Android Development] xThe Enforcer:
Live in South Florida and just went from JL2 to JKV.

Big jump and loving it! Get nothing lower than 3.20-4.05 down.

Any tips on how to make the modem faster? I just flashed from JL2 to JKC through CWM.
[Captivate Android Development] shoman94:
lol.... why are alot of people saying JKV when it's JVK. Just funny to me.

Nothing can be done that I'm aware of.
[Captivate Android Development] xThe Enforcer:
Meant to say, "JVK". Quoted the other guys post and wasn't paying attention... Lol.

Thanks to you, that's why I changed to JVK.

I'll thank your post!
[Captivate Android Development] grkmaster:
I actually had trouble catching 850 sometimes when flashing jl2 but I forced it and continyed on with the next modem to continue the trick
[Captivate Android Development] Hivol:
Im currently running Firefly 2.7 with Onyx 2.0.3. I have tried everything I have read to get the JQ1 modem to work. When im in town, it is fantastic. Wcdma 850 works great and it sips battery better than anything else Ive tried. The problem is when I go home after work, we only have gsm available. The modem will not switch from wcdma to gsm automatically like most others do. I can set it manually through settings but then it wont switch back and I have to go thru the whole process to get 850 back. Any ideas on how to get this to work? Currently using JS1 and its ok, but jq1 is faster and much better on battery.

Thanks to everyone who helps make these discussions possible!

[Captivate Android Development] shoman94:
To get 850 back again after, all you have to do is choose automatic then go into combo bands and add it back in.

Should work fine.
[Captivate Android Development] Hivol:
Thanks shoman, Ill try that. Anyway to make it switch between gsm and wcdma automatically?

Sent from 2 cans tied together with string.
[Captivate Android Development] shoman94:
It should just work but you can try what I told you...then select wcdma850 only then go into combo bands and add 1900 and 850 and 1900 in gsm...so you'll have 4 bands enabled.
[Captivate Android Development] Hivol:
Yeah that's what I thought as well. I did enable the gsm bands and set it back to automatic, but it would just stay on gsm band and not switch over back in town. I have an eary model captivate so it may just be the phone. I would sure love to have the battery savings tho!

Another with a working js1. Did the same trick to make it work?
[Captivate Android Development] caanda45:
Well after a little experimenting I think my issues on battery drain are JVK and Onix 2.02. I switched to SpeedMod KC 13D and JQ1 and the drain stopped from approximately 5 to 7% an hour back to 1% a hour. I still have to test further and isolate if it is the modem more than the kernel and vice versa.

Once I find that it is the kernel (which I think it is) I will go to JS1 which I know does work, just have to see how well it works!!!

Hey shoman, it would be interesting to hear your thoughts on DVJH3 modem. It's an eclair modem ( still works with froyo and ginger) that my carrier Telstra uses. Telstra has the largest and fastest (42mbps) 850mhz network in the world. I still use it on my JVK rom. Just would be interesting to see what you think of it compared to the other modems. I have attached the modem.bin for it to my post. Just flash in ODIN as phone only if you want to try. Not sure how to make cwm package.

Updated JL2

Just giving you guys here the heads up. There is an updated JL2 out. Care to test Shoman?
[Captivate Android Development] shoman94:
Interesting I will try it out....

[Captivate Android Development] harpo1:
I searched google and can't find anything about this. Can you give me a link where I can find more info about this modem?

Edit: Never mind I found the info on it. Thanks Angel.
[Captivate Android Development] shoman94:
Wow.... everything is coming out....

Where did you find it?
[Captivate Android Development] {Angel}:
From the i9000 forums. A user updated from Kies and was kind enough to extract the modem. I just packaged the modem for CWM.
[Captivate Android Development] harpo1:
Does it have 850 by default?
[Captivate Android Development] {Angel}:
Yes it does.
[Captivate Android Development] harpo1:
Thanks. I'm having great success with JVK but I may just give this a try.
[Captivate Android Development] shoman94:
I don't recommend this modem since it causes battery drain. The phone would never go to sleep using this modem.... probably an incompatibility with using an eclair modem on a froyo based rom.
[Captivate Android Development] shoman94:
I just installed it... will check it out.... also test it through the day tomorrow and see if it stacks up to JVK.

UGKC1 has a timestamp of 2011-Mar-4 in the binary. Will be interesting to see how it stacks up. Keep us posted.

Testing JS1 on CM7 and not too impressed with battery life, though speed was great. Flashed KC1 an hour ago and speeds matched JS1. Can't tell if it's on 850 or 1900 in CM7.

This is a shot of my battery usage this morning. The break in the graph is when I flashed KC1.
[Captivate Android Development] shoman94:
I saw that timestamp... I'm optimistic.

So far my initial speed test are on par speed wise midday here at my home. 2.8x-3.2x mbps with the quicker speeds in 850mhz. Upload speeds are still capped in 850 at basically 1.33mbps but upload in 1900mhz is not as good.... I'm getting .55 to .80 mbps UL on 1900mhz. I will retest these late night tonight when I know the network is not being used. Also tomorrow I will test in many different environments.
[Captivate Android Development] mrhaley30705:
Ok, I tried the KC1 modem and decided top flash back to jq1. When I did, I lost ALL HSDPA/HSUPA. Not knowing how to fix it, after I tried the full flash sequence from shomans instruction. No luck. Still no HSPA. When checking settings, it said HSDPA 0,HSUPA 0. At this point I decided to reflash rom(that fixed it).
