JV9 working well for me

Since coming from JVO I've noticed that:
Good
In the browser about:useragent works again.
No AndroidOS bug (so far)
Speed is good
Bad
Browser scrolling ('feature') of two pages at a time still present
Shut down sound still doesn't play

Have you tried playing any 3d games to test see if the android os battery drain bug is still present? Apparently most gameloft games, cordy and bonsai blast are known to cause it

I played the Polarbit game Raging Thunder 2 yesterday for an hour. That used to cause the battery drain, but it doesn't anymore.

Just finished playing Asphalt 5 for 20 minutes.
No battery drain.

hi, what region is this jv9 for?
Is it XEU??

JV9 has so far worked exceeding well for me, too! This, coming from JVK modem, on CM7...

Hey, isn't BUJV9 UK branded Vodafone firmware? I would like to know if the firmware has any Vodafone branding or apps if I install this firmware.
Thanks.

Its vodafone. The only added app i could see is a '360 update' app, for OTA updates i think. Easy enough to remove. And no branding. I installed Brotuck's rom on top anyway.

No Android OS bug you say.. I might have to check it out!

I'm curious did you flash the KC1 modem on top of JV9? If yes, how are you finding the reception?

hm interesting..
I might try to flash it tonight.
Can I still use CF-root JVO for this firmware too?
Please share your experience with android OS battery drain!
I would like to make sure this bug is gone before I flash it

Like has been said, the only 'branding' is a Vodafone 360 app.
I'm using the phone heavily and getting at least 16 hours out of it.
Gaming, GPS, WiFi and listening to music over Bluetooth. No battery drain as yet.
The one thing I'm doing different from when I was on JVO is that the phone is unrooted.
I'll root soon and see if any issues pop up.

Ok...I had left my phone on the table for about 20 minutes. Wifi was activated, but screen was off.
Looked at battery stats and saw that Android OS was on 29% where it had previously been 4% earlier in the day.
The last apps I had run were music player (over Bluetooth), and MyTracks.
Seems it's not quite fixed, but it seems better than JVO.

Was just about to install it and give it a try but I guess I'll wait a while longer until Samsung or someone can fix the battery drain issue. Thanks for testing and letting us know

Which locales are included in this firmware?
Is the browser finally fixed?

I have never had good success with battery life with the KC1 modem, i use JVE and the trick to activate the 850 band. Whatever i do though, i cant activate it on JV3 modem, so i stick with JVE. Reception and voice quality is good.
I haven't encountered the android OS bug myself, but i'm working from a very clean fresh phone.

KC1 works well if the reception is poor and you have to use other network's signal and not Bell's. I've had JVO on 850 come up as network not available in locations KC1 had no problem connecting in. And if you're like me skiing or hiking in the backcountry, not having a signal is an option not worth having.
Good informative thread, by the way.

Browser scrolling is still only a few pages at a time and not end to end scrolling like Froyo.
Android OS issue I had may have been due to leaving WiFi selected because it hasn't happened again in normal phone use.
Battery life is generally good.

Thanks.

KG6 modem very fast

I'm trying the new kg6 modem in Cyanogenmod and miui rom, since I've 2 galaxy s for testing. I notice a very speedy call connecting, seems to be very better different from the good kg3.
So you notice it too?
Sent from my GT-I9100 using XDA App

i have done now speedtest. With kg3 download speed 1600kb now 2100kb. Upload 1400 and now 1600.
Also little 3g h h+ fixed, now swapping only one time when you use the mobile data.
And also seems to be that reception signal bar have got a different calibration (or more device sensibility to mobile signal)

Anyone got a link to the modem zip file?

i tried this modem and it drained my battery like mad compared to kg3/kf2 that i have used before this one.
data speeds were ok but signal was really really low hence the draining of my battery .

KG6 improved broadband connectivity a lot for me, always getting "H" now. It's true that its draining more battery, but I also installed Lite'ning v5 ROM (which is KG6 based), so I can't tell exactly if the extra battery drain is only due to the modem component of the KG6 release or to some other custom-kernel related issues.

I'm not sure if it's placebo effect or not. But it does seem improve the 3G, H+ speed quite a bit. I'm with AT&T in NYC but just did a test, the download speed broke 5mbps for the first time ever.

My 3G connection has sped up significantly and I am also finding that I have reception in places that I usually would not.
YAYY

Yes, my signal seems to be much better than KG2 and this was the first time i got a 7.5mbps download speed.

I use KG6 and have no excess battery drain .
|I have an increase of about 10% in WiFi strength over KG3 .
jje

Best for me so far,had no probs with it draining the batt.

I downloaded and installed this modem on my SGS1, and it worked. More than worked, it was amazing. Problem is now that I'm reading about it, potentially was a mistake and harmful to the phone. Any thoughts?

You will probably be ok with a modem on SGS1 ..
KH3 faster for me in all tests .

How does it compare to KH3?

here is the zip file

[Q] Best Stock Rom For Daily Use ?

Hi everyone !
I´ve been flashing roms frequently for like a year or so, testing each and every rom released.
Ones are clearly better than others,but every developer is making a good job.
The thing is, since my last 3 flashes,i'm experiencing a HUGE battery drain once i'm over 3G network, so i'm considering flashing a STOCK rom so i can use my phone correctly.
Which is the best BASE ROM i can have ? (JPS,JPQ,JPM... 2.2 Froyo ofc).
I'm tired of flashing and reflashing things that are not working 100%, stability is VERY important.
Also, any idea of whats happening to my 3G ? My battery life is OK once i'm not using the 3G network,but once i turn it on my battery goes down like water in a waterfall.
Thanks in advance.

JPM was very stable. But you can try JPS too.

Actually, all i need is a rom that does not EAT my battery over 3G network.
I guess i've messed up my battery flashing all those roms.
Since i've already calibrated it 3 times and it still draining as much as it was before the whole process

Over 3G usage ...you will definitely get low battery, due to resource usage over the high speed network.
Try My ROM and let me know if it helps your cause ... though my ROM is based on XXJPS and have lots of battery Customization to improve performance the battery backup as well.

I dont think it is normal to have my battery drained like hell over 3G Networks...
I mean,i wasnt like that,it started someday and never stopped.
Do you think that flashing a STOCK rom would fix it ?
All i want is to be able to stay connected to 3G for like 4-5 hours,maybe more.
If i turn it on,my battery drops to ZERO in matter of minutes.

Then its time to change your battery.same thing happens with me.i have already changed so many roms...but after data network on battery drops in 10min...

8 hours gone and I'm left with 49%. With the standby estimation, I should be good to go through out the night. So I hope it should be the same as previous. Just note that I'm a moderate user .

Draining like hell. Can't even last for a day due to radio issue . The issue is there in .283 & .42.

i've not seen a fw that had great battery life...
on cm041, miui the drain was there as well....
what is wrong here....

Slightly off topic: I'm getting about 8-10 hours with pretty heavy usage on CM7.1.0.1. When I leave it on standby, I have about 10% drain after about 8-9 hours of standby, with the occasional time check.
And back to topic, thanks for having the generic SG ROM here, I might go back to this as I have some issues with Wi-Fi tethering on CM7.

Just to add on, i had previously used the .283 version, battery was good. Then i started to root and unlock bootloader, and installed the doomlord v12 for .283, battery drain about 10-15% overnight in 6hrs. Days back, I had flashed the SG ROM .042, the battery was good again, averaging 3% overnight. Its proven to be good.

3% drain overnight is impressive. Which kernel are you using? Stock .0.42?

Same experience as me. But I turn off the data connectivity at night.

As far I used (I used almost all the versions, I guess) the .368 firmware is the best of battery usage. I usually get 24-26 hrs of usage (I would say pretty heavy, with all guns up... [BT, WiFi, GPS]) out of it, compared to this .42 firmware, I can't cross 15 hrs mark!!!
But from what I experimented, I understand that it's the baseband that is giving problem. I notice that there are many users from SG here and specially from SingTel, if you guys observe closely, the network coverage is poor with this firmware compared to the previous .145 firmware. So I'm planning to flash back the old baseband on to the new firmware and give a try whether the battery life improves together with the network coverage.

How do I know which firmware I am using?

Ok, I am on .0.42 world generic now. Let me monitor and revert.

I'm on stock kernel, and i'm using Juice defender Ultimate, let it auto manage my battery-drain stuffs, so i need no worry on forgetting to switch off any batt drain functions. I"m not sure if the SETCPU profiles works, I just enable the profile when screen off I set to 245MHz max 122MHz min. Mine is M1 set.
Kinda tired of flashing custom rom/kernel.. there's always some problem with the features, i.e. 0 batt, wifi cannot connect, batt drain etc etc.. stick to stock for the moment.. Root hp is good enough to play with some stuffs for the moment. Especially ad free.

Personally I don't like any programs that turns off my data to save the battery. It defects the purpose of having data plan moreover, you miss the updates (I've tried lot of applications like Juice defender and I experience the same issue...missing the updates, even the Whatsapp messages are not delivered to you on time).
Now I've flashed the old baseband (from UK .368 firmware) on to the latest firmware (.42 SG) for testing to see how is the battery drainage

bad battery ;( (mobile data eating it up)

* Just listening to TuneIn radio during the night as I fall asleep (a tiny 32kbit stream) = 6 hours batterylife on fresh charge. My old SGS2 was still playing radio when I woke up. The SGS4 dies during the night. (even though SGS2 had 1650mAh, and SGS4 has 2600mAh. WTF.)
* Browsing internet using Dolphin and max brightness = roughly 10 hours total, with roughly 3h30m screen time
* some browsing, some poweramp, mostly deep sleep = roughly 20 hours total
* mobile data OFF = 6 hours screen time (which is why mobile data is probably the culprit in my specific case)
I recently installed BBB, and this is what I found on a fresh charge cycle, after about 2,5 hours of using mobile data (screen OFF) and from 100% is now just 85%. again, SCREEN OFF and mobile data has eaten up 15% in 2.5 hours. Ive been downloading stuff, screen on total 5m)
msm_hsic_host (29%)
fast_dormancy (21%)
powermanagementservice (11%)
Ive noticed these three are mostly in the top when using my phone normally during a day.
My phone is 6 days old. Its on the 9th cycle or something like this.
I tried Stock MF8 rom + MF8 kernel (Battery King and Omega)
I also tried GE kernel ausdim, aswell as stock.
I recently upgraded rom to Wanamlites MGA + Adam kernel and I see alot of general improvements as to battery and heating.
Although I am still far from satisfied.
I tried disabling Fast Dormancy using Gokhanmoral app for the S3, but that did not change anything at all. FD still at about 15%+ as it was yesterday with FD Enabled.
My Carrier is 3(SE) which DoES support Fast Dormancy 8.
any advice on the issues, especially the first wakelock which I cant seem to find anything on?!
I found on Nexus 4 this issue but not SGS4.

Sorry to say but I think we will have to wait for a fix from google.. seems the problem is with jelly bean..
I have tried almost all custom roms and using the latest firmware.... but no use..media server still eats too much battery.. there is hardly any deep sleep...
Yea there maybe a few tweaks you may apply using 3rd party softwares to optimize battery at the existing inefficient level....

Yes with flight mode i also get excellent battery.
Thanks I'll try the stock 3(Se) modem from may like it was when I got phone.
Think it was MEA or something.

Just realized MGA is also for my region and carrier same as MEA do I doubt it will be different but I'll try later.
Another thing is, could bad reception be a battery drain too?
Cus I've been on holiday past week and connection is between 3g, h+ and no data constantly. Also GSM is constantly no bars to 2 bars.
Could this constant change and bad reception be reason for the msm_hsic_host wakelock?
