I'll try it soon but I'm leaving in the morning for florida so... we'll see
[Captivate Android Development] shoman94:
Try XXJVK or ZSJPG...
[Captivate Android Development] LNJ:
Will do. So far it's been good.
[Captivate Android Development] Shoey Peachew:
I noticed this. JK4 lasts all day and night, but when I flashed JPG it killed my battery. I just flashed KC1 and noticed battery life might not be as good. I'm going to fully charge my phone, wipe battery stats and test it for the next couple of days.

briefly tested jp9 for speed tests and signal strength against jvk and found in the same spot a few minutes apart that jp9 was not quite as good as jvk.... at least in those two departments.....my only internet connection right now is the mobile ap so i'll stick with jvk untill i,ve got more freedom to play....

thanks angel for bringing the goods..... keep'm coming ;)
[Captivate Android Development] WickedNite:
I live at the valley here in Los Angeles, I'm using KC1 right now since they said it is good. I wonder if this is the best bet for me instead of JQ1 or JVK?
[Captivate Android Development] shoman94:
IMO yes but I haven't tried JP9. It's suppose to be 850 enabled by default.... give it a go.
[Captivate Android Development] WickedNite:
So KC1 is best for me? I'm gonna try JP9 later tomorrow.

Hey guys!

I'm on XWJS8 (Doc 9.5.5, and I'm probably staying there for a while) and I mostly care about battery life, and Wi-Fi signal. But battery life goes first. GPS is secondary, and I couldn't care less about 3G, because I don't use it, it's damn expensive around here.

The modem I've used previously sucked balls in terms of battery life (XXJQ1), and I just installed UGJL2 in hopes of a better experience.

What are your suggestions on the matter?
[Captivate Android Development] johnsonxray:
hey shoman any idea which modem has the best signal and thus best battery life for south east asia? like singapore malaysia
[Captivate Android Development] shoman94:
I don't live there so I can't really say... But I would try xxjvk and szjpg.
[Captivate Android Development] Demonic240:
I've noticed this too. However, when first flashing JQ1 and checking the band selection it will display that it's set to WCDMA 850, but if you check the GSM status it is only using WCDMA 1900. When changing from the 850 option and trying to go back, I get the error message that 850 doesn't exist. This only happens on JQ1 and happens each time I flash it.
[Captivate Android Development] eliminat:
You need to follow shoman's method to flash the modem, and then it will only enable from the Combi Band menu, not from the WCDMA menu.
[Captivate Android Development] shoman94:
If you boot up and 850 is not connected, you didn't follow my process correctly. It's pretty clear what to do in my sig if you haven't tried that.
[Captivate Android Development] xreflection:
KP1 gives me crap call quality. I switched back to TL3.
[Captivate Android Development] Demonic240:
Followed your steps and installed JVK. Looks like 850 is working now. My next question.. your spreadsheet shows that JVK got d/l speeds of 3.8. Is this a results may vary or should I be seeing that too? I'm only getting 1.1 from dslreports.
[Captivate Android Development] sicmadek:
Which is overall better, jpg or kc1?
[Captivate Android Development] shoman94:
Area specific....
[Captivate Android Development] LNJ:
So I'm pleased with bjp9. Comparable to kc1.

However both kc1 and bjp9 has a little data lag as in it takes a little while to kick in. Jvk did not have this lag.

[Captivate Android Development] sicmadek:
Does the jpg default to 850 like the kc1?
[Captivate Android Development] harpo1:
There's two versions of jpg one does and the other doesn't. If you meant to type jp9 then yes it does.
[Captivate Android Development] {Angel}:
I have been getting great battery results with jp9. Jl2 is pretty good with battery life too. Keep in mind your results may vary depending on your provider, region and phone setup, etc. Keep trying until you find oneyou are happy with. Remember to have your bat properly calibrated.
[Captivate Android Development] {Angel}:
I have not noticed that on my end. Data has been quite snappy so far but that could be my network. I will be tying it out for a few more days to give it a fair assessment but so far for me it has the right balance of qualty, signal and battery. I am getting far better battery life compared with kc1. Seems like i can finally start using my phone and not worry :)
[Captivate Android Development] WickedNite:
JP9 requires the magic steps, right? Or the 850 is enabled by default?

Captivate, Serendipity, XDA Premium
[Captivate Android Development] LNJ:
Yeah battery life is better than kc1 for sure. Data speed is good to but it takes a while to initiate for some reason.

Has anyone else noticed that sometimes when you install a modem you get amazing and great results, and other times not so much?

I was on JVK and lost something like 25% off per day with wifi off and cell data disabling when screen off. flashed to another modem, decided it was not that great and so went back to JVK. Flashed the exact same way and file as i did before and now am losing battery fast. connected to the same bands (850) and in the same location as always.

Does anyone else experience this?
[Captivate Android Development] Ikonomi:
Maybe a dumb question, but have you checked whether you're experiencing the 50% time without signal bug? You can see your time without signal under the Cell Standby entry in the Battery Use screen. This bug causes your radio to search much more than it should for signal and can ruin your battery life.

Toggling airplane mode after a reboot, or rebooting in airplane mode (my personal preference) will prevent this.

I actually just checked my standby and I've got the 50% -- forgot to toggle airplane mode after a low battery shutdown earlier.

Again, if you knew all of this already, my apologies.

Question

Im on serendipity 6.3 and i live in allegany county maryland and i was wondering what the best modem for the area is and how to install it correctly.
[Captivate Android Development] perosredo:
Just a quick poll...

Is anyone having any GPS issues with KC1? If so, which ROM and kernel?
[Captivate Android Development] kb9nvh:
I'm loving KC1 and my GPS is as good as its ever been with the modem (not saying much). I'm on Paragon RC6 with KC1 modem and its way more stable than JK4 for me here in southern indiana (non-3G land)
[Captivate Android Development] fractaline:
Jp9 and kc1 are the most recent default 850 modems, simple to flash... Good place to start.

I still use jvk as I find it's the best for data speeds.

But there is alot of different results so try them out....

Flash away it's easy and safe.

[Captivate Android Development] markmunsch:
Hey just a quick question, has anyone else tried going from say UBKC1 to one of the non 850 default modems and keeping 850? I tried it going from KC1 to JVK and it didn't seem to set 850, JVK would hold onto 1900 at -110 when on KC1 in the same spot i had -90 on 850. Didn't know if KC1 could work to switch over or if you still have to do the flashing trick.
[Captivate Android Development] pwnerman:
so all i do is place the kc1 modem on the sd card and install in recovery?
[Captivate Android Development] fractaline:
Use jjpd as the bridge.. Only need to do it once.

Mine worked without the combi band trick. Just flashed jjpd for about ten minutes. I've since used native 850 modems and back to jvk no problem...

When I was testing modems, I found that after flashing KC1, I had flash JK4 and JPD at 850 to get JS1 to connect at 850.
[Captivate Android Development] fractaline:
Interesting.... And I know that a few people have gotten jpg to work on 850 without jpd.

Some need to do the combi band style force 850 some not..

I guess the moral of the story is.. If you want to really know which modem will be best for you, test it and some others yourself, in your locale, with your phone and your carrier.....

[Captivate Android Development] MPKO:
Hi all, I have notice that some people here are a bit wondering or don't fully understand the meaning of dbm and asu. Hopefully I can help a bit.

If you are using a widget which shows these two values like dbm and asu, dbm gives the information of rscp (radio signal common pilot power) measured by your phone. Good value is > -95dbm. ASU is then the measured code power what your phone is using at that point of time (energy per chip, ec/lo) and measured by your phone. Good value for this is normally > -10 and better these values are, higher throughput and less battery your mobile will consume. Operators are triggering band selection and handovers based on these values. In case of data service, normally used values are around -105dbm or -10 (asu). It is also good to remember that in case of hspa your throughput debends not only from these values,but also where you are located and how many other users there is under that same location (cell), because all the "cell" resources are shared equally between all the users depending what is your phone capability and capacity of that cell/site. If you have questions related to this, let me know:-)

Cheers

[Captivate Android Development] mirotvorets:
hi guys. maybe you can help me.

I had a ROM andromeda 1.2 with JPG modem. I don't use WCDMA band because weak signal on it, my phone always work with "GSM only" setting.

in our city the basic and stable band of network provider is GSM 900. day before yesterday i decided to try JL3 modem. I didn't like it, and i installed JPG modem again. now I have the phone with not working GSM 900 network on JPG modem (and LIMITED network on GSM1800). i tried another I9000 modem: JPY,JVK (before i've tested these modems, its work without any troubles) and i have the same trouble:GSM 900 band don't work. when i install JL3 modem(or JK4, JL2) the phone work fine on GSM 900 and GSM1800.

what's happens? how does make the phone work on GSM900 band on JPG modem?

i've restored backup of ndvata.bin and unlocked the phone again even, it didn't help.
[Captivate Android Development] H3llstorm:
Check Settings > About phone > Battery use > Cell standby

If Time without signal is 50%, that will drain your battery very quickly.

Enable and disable Flight mode in the Wireless and network settings, and you should be fine.
[Captivate Android Development] LNJ:
What causes this?

I just checked mine and it was @ 50% and probably explains my drain in the past few days. Enabled and disabled flight mode and it dropped to 49%

Im going to be in San Antonio on Thursday till Monday - anyone around there have any good experience with any of these modems and which one it is? Battery life is going to be key for this trip!
[Captivate Android Development] H3llstorm:
This bug has been floating around various ROM/modem/kernel threads for a while now. So far, no one has figured out a fix. Using flight mode is a workaround until a fix is found.
[Captivate Android Development] {Angel}:
A quick search seems to indicate this is a long standing bug in android unfortunately. This has happened to me at times and recently my phone dropped 6 % in 1 hour idle and when I checked my phone never went to sleep since I unplugged it, a reboot fixed it. I have accustomed myself to check the battery usage and history every time I reboot or unplug the phone.
[Captivate Android Development] LNJ:
Thanks guys. I never experienced it on my previous Android phone. I'll have to watch for this on my other Captive as well now!

Btw it went down to 28% now

Edit: i just realized that Asu is not eclo when I was following the signal strength. Have been working with rf over ten years and don't really understand for what this asu is really used. In other phones there is normally mainly two measurements available (eclo and rscp). Have to check this... sorry about my misleading ASU analysis...

I would like to see a write up on the meaning of all the parameters on the secret code screens for gsm status. Entries appear and disappear depending on data or whatever and there are different ones for gsm or wcdma. Then it seems even different for 1900 to 850 band. I googled it...not finding much.

Lots of great info in this threat regarding modems, thanks for all the research.

Slightly off topic, I found (via another forum) a detailed study on the benefits of 850 over 1900 regarding signal strength:

My girlfriend is running darky rom 9.5, dark core 1.4 kernel and ugkc1. She receives frequent data lockups and it switches between 3g and h. It takes forever to finish a speed test and I'm close to the towers. Its running on 850mhz correctly. Any ideas on how to troubleshoot?

Have you tried a different ROM or kernel? (see my sig for my setup)
[Captivate Android Development] TonyStark R.I.P.:
Are you running standard OC or OC-1000? I'm running 2.0.4 OC and this is my test. though great, battery still isn't what I'd like.

[Captivate Android Development] Pirateghost:
according to your location and your device....this thread doesnt even apply to you...
[Captivate Android Development] rootnik:
Not bad. There are just not any 850 frequencies in your area.

You can still force it to use a specific band. Try that 2100, but keep in mind that if you start dropping signal (or if you travel) you will want to go back to automatic.
[Captivate Android Development] SAEVARM3:
I wouldn´t say that.... I flashed "UGJL2 Modem" and my battery life got much better.
[Captivate Android Development] Pirateghost:
sorry, i meant in regards to the 850 band. my guess is 850 band means nothing where you are
[Captivate Android Development] nkrick:
AFAIK, the 850 band is only used for "3G" in parts of the US, Canada, and maybe parts of China. Europe uses 2100 exclusively for 3G, as does Korea. If your phone supports the 850 band, it doesn't hurt to have it enabled if you are planning on traveling outside of Europe, but while in Europe, you will always be using 2100.
[Captivate Android Development] VQ30DE:
This morning when I woke up my phone said "no service", despite the fact that reception is fine in my house. It was giving me signal strength of -69 dB and said "Edge" (no 3G in the town I'm in) but still said no service. I made sure auto band selection was still on and then rebooted the phone. After a few minutes it came back with normal reception. Currently I'm using KP1 but it also happened with JK4. Any ideas? I'm using the Continuum ROM with the VA Green theme.
[Captivate Android Development] neotekz:
for us canadians that are on rogers network which is the best modem to get HSUPA speeds. i've tried JL2 and KP1 and JI6 to try to get HSUPA but didnt really notice much a difference over the stock JL1 in download speeds. i get on average download of 4-500kB/s using speed test. what modem is giving you the best downloads speed on rogers network?
[Captivate Android Development] tiuk:
I'm on rogers. Best i've used were kp1, ugjl2, and jl3. Currently on ugjl2, seems to be the best balance of signal strength, speed, and gps consistency. Znkp1 was a close second for me.
[Captivate Android Development] neotekz:
can you post the download speeds you are getting too?

[Captivate Android Development] markmunsch:
I hate to be the "dumb" person on this thread but want to make sure that all the modems posted on the first page are CWM flashable? Been looking for a new modem because JK4 that came with Perception 10.2 is not working for me, when driving I can't hear anything on a call and the person I'm calling can't hear me, but otherwise it works good. Also, modems are easily just flashed over each other? Just really getting into this flashing of everything, so wanting as much info as possible so I don't become the owner of a paperweight
[Captivate Android Development] x3nhydr4lutr1sx:
yes, they are all cwm flashable. and if they weren't, cwm would complain instead of trying to flash something that isn't flashable. and yes they can be flashed over each other, since the modem is actually just a single file, and each new flash of a modem overwrites only that single file, so there's no worry about mysterious force closes.
[Captivate Android Development] tiuk:
Speeds vary based on reception. With 4 bars I'd get about 4 mbps down, 3 mbps up with kp1, probably an average of 500 kbps less both ways with jl2. Jl3 was lower. Sticking with jl2 over kp1 because although the speeds are a bit lower gps seems to get a lock faster/more satellites and signal strength seems a bit better on average. Ymmv of course, just depends on your area. Jl2 and kp1 were quite close.
[Captivate Android Development] daCLOUD:
dude actually I've found this to be the case with ALL I9000 based ROMs. Its something with the internal Captivate mic and the i9000 ROMs when there is a lot of background noise. Its not only when you are on a call either, it happens with the voice memo recorder too. Flashing a different modem wont resolve it. If you have a load exhaust on your car your screwed...I had to either use my bluetooth or earphones with a mic on em.
[Captivate Android Development] loraque:
Oh ye modem experts. Is Bluetooth controlled via the modem? It gets turned off in airplane mode along with everything else, and is a transmission, so I was assuming yes. But before I go on with my question, I figure I better straighten that out first :).

Bluetooth uses the modem, right?
[Captivate Android Development] markmunsch:
KP1

Well finally flashed a new modem, and yes thanks all, that was very easy and painless. So far loving KP1, GPS is amazing, sound quality so far is good, and I'm not really concerned about the data speeds. So as long as call quality stays good and the battery life is decent/good, KP1 will be a keeper for me.
[Captivate Android Development] dave1977nj:
Can you post the I9000XWJS3 modem? Thanks

[Captivate Android Development] dmnall:
Well I just flashed my phone with kp1 and damn gps locked in 10 seconds, speeds are equivalent to jk4 which was what I was running by default with perception 10.2. I am going to keep using this kp1 for the next couple of days and see how it runs. For now it is definitely faster the jk4 by a long shot and definitely like the gps lock.

[Captivate Android Development] H3llstorm:

[Captivate Android Development] TonyStark R.I.P.:
Wait... isn't that what we all strive for
[Captivate Android Development] {Angel}:
switching between 3g and H is nomal. It switches to H when its available and data is being used. If not then it sits in 3g. This is to save battery as H is more expensive.
[Captivate Android Development] {Angel}:
That should not do anything to add to signal strength. But it should be ok but when your 850 coverage drops the phone won't swtich to another band with better signal.
[Captivate Android Development] TonyStark R.I.P.:
Thanks guess I'll flash ONIX 2.0.5 see if that betters my batt. Using wdcma 850 (xhrpzt... what ever what ever) isn't gonna to do it. Sig dropped from 5 bars to 1
[Captivate Android Development] {Angel}:
Same here. JP9 has been the best for battery life for me.
[Captivate Android Development] LNJ:
I thought 3g is default for voice and data and H is only during data and falls back to 3g, E or G where H is not available.
[Captivate Android Development] {Angel}:
Yeah that's exactly what I said, or meant to say. It bumps up to H for data if it's available then goes back to 3G when not in use.
[Captivate Android Development] WickedNite:
Cause some say that we should select automatic instead of forcing WCDMA.
