There's been a lot of discussion about the low WiFi signal from most, if not all, of the Gingerbread builds. Many have speculated that it's simply a display issue and not a performance one.
My wife has a stock ROM (Froyo) and I have the GB build KH1. I did a test comparison of both the WiFi download speeds and the 4G performance.
The KH1 ROM *way* underperformed the Froyo one -- to the point where her stock ROM was at least 2-3x as fast as the KH1 build. 4G performed similarly. WiFi Analyzer also showed a huge difference in signal strength.
I then installed the KH2 modem and tried the same experiment and while it improved it somewhat, it was still woefully lacking in speed over the stock Froyo ROM.
With that said, has anyone found a prior modem build that works better than what's been released recently? This is a huge issue for me and while I love the GB build, to lose that much connectivity speed is troublesome.
There is a thread with all the modems on them, check the bible, you can flash each one to see which is best for you.

I don't think its a modem issue with gb. I've tried them all, wifi still sucks.

Yeah not much you can do here, there will be more leaks..as wifi is still horrible and unacceptable for such an expensive phone..samsung just have to get it right!!
Thanks for the info and confirmation. I was afraid that we'd have to wait for the CM7 release. I've tried several of the modem releases and nothing has worked any better.

yeah its just gb..if its really important just flash back to froyo..but theres good benifits for gb..netflix,skype video calling,better battery life..and all around smoother

I just jumped in neck deep and flashed the latest GB rom KII, Doc's new kernel and was surprised at my wifi speeds. before on stock froyo my wifi was sluggish and intermittent. Now as a matter of fact my whole phone is faster, very snappy. I'm very happy seems like I got a new phone with a duel core cpu
Thanks to all!
ok so i got my charge 2 days ago and am rooted with Gingerbread leak,
so i have some questions.
First: is there roms for gingerbread? because i couldn't find any.
Second: what kernels are there for GB? can i use PBJ?
Third: now ever since i got the phone it drains batter pretty quick with everything off. and hardly using it maybe about 20% per hour. i tried undervolting with Setcpu but wasn't successful, so what app do you guys recommend to undervolt the charge? or any guides to do so?
thanks,
Check out the development section. Gummy Charged GBE is great

I did, thanks for the reply. now i have voodoo and on the recovery sais enable 100mhv something like that. is that so i would get more battery?
You can't undervolt on gb because its a leak meaning no kernel source.
I think setcpu will let you underclock which would give better battery life but reduce performance considerably.

Whenever you change roms, you should calibrate your battery. It works wonders

You need to return to stock, then fresh Odin GummyCharged GBE 1.9RC2.3 if you want Gingerbread as it's really the only modified Gingerbread rom. Eclipse is available, but i'm not sure if the dev still supports it or not. The quick battery drain is something that goes along with the fact Gingerbread is a leak. GummyCharged team has done a wonderful job with minimizing this drain. I have found it actually has better battery life than Froyo. That's just my personal experience.
Hi - I installed the Valhalla 1.3.2 yesterday and then flashed KJ6 modem since i heard KJ6 has better wifi signals, but when i try to connect to wifi i still see poor signal. Is there any fix available for this ?
Not really. I have not noticed any real difference with any of the gb modems.
Sent from my SGH-T959V using xda premium
If you must have wifi, use odexed KJ6 (odin version) and root with Doomlord's method. It's almost perfect imho.
The bad part is you lose cwm & ext4.
KJ6 for me definitely was an improvement, however, it's not as good as Froyo was.

Are you using a deodexed rom?
All GB roms have poor wifi. Once GB becomes official you would hope that type of connection get's better. If not Froyo is still an option if you realy need wifi
Yeah kj6 improved wifi but it still unacceptable compare to froyo and a official gb

has anyone been brave enough to find a modem from another Galaxy S phone with the same hardware? It might be an option. Its only a guess though because I am by no means an expert.

I started on KI3 when I went from FroYo to Octane GB 2.3.5 and then switched to KJ6. both have been around -65db when Im about 10 feet away from the router. on FroYo I was usually around -45db.
The strange part is i upgraded to Valhalla 1.3.2 from Stock leak 2.3.5 KI1 and it was working perfectly. Earlier when i was in KI1 my battery life was amazing used to get around 2 full days now after upgrading to Valhalla it is draining very fast. I have already installed Juice defender and Andreline Tweak v12.
I also have expetienced these issues. I foubd Black Ice was most reliable, followed by Octaine, and then Valhalla 1.3.2. I also find that. Wifi does more poorly on low battery (<35%) but I know voltage should be a constant so there's no rationale to that behavior I can divine. Its not an anecdotal observation though, I ran the DbM timeline and it supported my suspicions. I wonder if this would be due to some software side battery optimizations Samsung threw in.
I eagerly anticipipate trying.the 2.3.6 kernel with fingers crossed.

The modem.bin doesn't control the wifi. If you want good wifi see my thread in the dev section
*the mod only works with 2.3.5 or higher
Sent from my SGH-T959V using XDA App
Tehgy is right about that, I think if there's any optimizations to be had they are modded through build.prop functions and possibly SysCtl also. Unless you have a healthy amount of development knowledge on a coding level, the only solutions are to rely on Tehgy and other more experoenxed developers and/or extensively test various combinations of ROM/Kernel flashes with as much isolation of usage variables as possible.
Do not count out anecdotal use case experiences as irrelevant, the sum of these observations helps developers to locate variance and provides clues as to where to begin searching or modifying relevant code.

Reason for this question is because I'm currently on the lastest leak ucle2 and my battery life is horrible. I would just flash and try it out but not completely comfortable with flashing roms. Any input would be really appreciated. If this topic has already been brought up sorry. I searched maybe not enough.

Battery life has been a present issue with the ICS leak so you are by far not the first one asking about this. My suggestion would be try out either CM9 or AOKP and see if your battery improves any because in my experience, I got much better battery life on CM9 and AOKP over any other ICS ROM. To flash is very easy just follow the directions in the OP and you will be rocking in no time at all
Great battery life on GB rom
Sent from my SAMSUNG-SGH-I727 using xda premium
This is my battery life with Sky ICS 4.2E-6. Light usage, strong cell and wifi reception. Probably could've been better if I uninstalled Kik and Line (they seem to wake up the device very often).
Usually, it's much worse during the weekday when I'm at work, where my cell and wifi reception both suck.
I ended up flashing sky ics and I have to say battery life is definitely amazing over ics ucle2 leak.

hi everyone,
this is actually directed to Jscott, regarding the ethereal last build 1.2
my question is:
I was using your stock at&t gb with root and cwm.
specifically your option 3 in the threar you posted over in development,
a few days ago ive been using the ethereal rom v1.2
ive been experiencing some differences vrs the stock gb uclb3.
is it possible that battery life is shortened with your rom?
could this be because of the kernel change? (stock has entropy's dd, ethereal infuzion core a)
lets assume kernel could be the cause, is it possible to flash entropys kernel into the ethereal rom? would it affect its performance?
lidroid toggles work partially in some cases, like flashlight wont turn on sometimes.
can the rom have issues regarding the response of the screen, in some cases it seems to fail to respond. have to push my finger a lil bit more to the screen.
im very new to this area of flashing roms and stuff. just wanted to say ethereal is very cool, you did a very nice job with this! thanks!
Since you directed your question to..the op of this ROM, question relayed....

Glad you're enjoying Ethereal. I'll tell you a little "secret". Ethereal is Option C from the Odin UCLB3 packages I put together. A few images and graphical values have been changed to make it look more custom, the launcher has been changed to AOSP, and lidroid toggles have been added. If lidroid toggles get a little wonky, as they have from time to time in most custom roms, a reboot should clear things up. As for battery use, I've had about the same for both stock and Ethereal. Most have reported good battery stats on the rom, but your mileage may vary based on how you use the phone and what apps you use. You may notice a slight difference when using Entropy512's daily driver kernel, as it was designed to provide good battery life. You can flash it with this rom if you would like to test. If you aren't comfortable flashing kernels, you may want to give Zen Arcade's Infuse Toolkit a try. It gives the option to try different kernels.

Thank you jscott...
your response much appreciated!
can I flash the kernel same way as in the post you made about using different kernels?
it's impressive it is option c. in performance they have alot of difference, ethereal has no lag whatsoever.
thats why I was asking if I change to entropy512 dd from infuzion, would that affect ethereals performance?

I personally get good performance with Entropy512's daily driver and Ethereal, and you can use any of the kernel flash methods (easiest being SGS Kernel Flasher from the Play store).

I've changed the kernel with sgs kernel flasher, gonna give it a shot how it goes. Where can you see what version of kernel the phone is using? I've tried in settings/ about phone, but that doesnt seem to change. Im not a heavy user like gaming and alot of texting, I just feel, what would you consider good battery life?

You can see the kernel information in Settings / About Phone. The kernel info is the same for both Zen's Infusion-Z and Entropy's Daily Driver since they are based on the same kernel. For battery life, I can get about a day and a half if I hardly use the phone. With moderate use, I have to plug it in when I go to sleep each night. That's about as good as I get for battery life on stock, on UCLB3 based custom roms, and on CM9. This is with keeping the phone in airplane mode and with wifi on when there is bad cell reception. This phone eats up battery when it searches for cell towers and can't find one. I also keep my screen as dim as possible, unless I'm outdoors, keep GPS off unless needed, and keep auto-rotation off unless needed. If I have a day where I use the phone heavily, and the screen is on for several hours at a time, I get about eight or nine hours, but top it off at work or in the car to make it through the day. This is pretty average for most modern smart phones.

Yeah thats right, everything is working quite alright with the kernel. seriously congrats on this Rom, works pretty damn good, i like how fast it is compared to the stock touchwiz based rom.

That's about it. If you like Ethereal, it's worth flashing 1.3 as this is the final release.

Love the mod , keep up the good work
Should follow same procedure as installing a new Rom right?

Yeah, I've seen this also. The only way to make that not happen is if I go in and change the remaining stock icons to match the ones that I've already modified. I'll get to that eventually.

Just fixed this, by the way, and will get an update out in the next day or so. There are a few other things I want to work on before putting out another release.
