Yeah, I've read many relevant hints on that point ... this is the first thing I checked and disabled but the damn cell's still draining my battery down ... that's why I thought the modem first install was not stable enough to keep it within the specs.

Can you hint me on "better battery stats" and "wakelocks" findings ?

---------- Post added at 08:05 PM ---------- Previous post was at 08:03 PM ----------

didn't get your point ... can you rephrase ?
[Galaxy S 4 Mini General] Loulou-13:
sorry .....

some members repport a battery drain problem ,but it may caused by others things like G apps for example........ but not the "modem" .
[Galaxy S 4 Mini General] ym58:
well, I think it's gonna be tough to investigate who the culprit is, then ... any advice is welcome, coz it "sucks" !
[Galaxy S 4 Mini General] Loulou-13:
And i'm with the modem ******UCOA2 on my CM11 ( my previous with my CM11 was *******UCNK1 ) ==> i don't have noticed difference for the battery-life ,and i have a little better bandwidth ,little fast .

flashed with the good method ...and 3 times !
[Galaxy S 4 Mini General] ym58:
Do you mean I should try and flash the same modem ?

(I can do that)
[Galaxy S 4 Mini General] Loulou-13:
it cost nothing ( just 1 or 2 quick minutes to flash) for to try ...... you will try during some days ........ yes !

If you are not satified ,you can flash others ...

when i flash the modem ,i do it 3 times !!! untick all the case (f-reset and autoreboot) and between flashes :switch-off the manualy the phone ( very long prees of "power") and then go to download-mode again .

i don't "reset" odin ,i just keep parameters and press "start" many times ...
[Galaxy S 4 Mini General] ym58:
which modem would you suggest me to flash over my XXUBNB3 and replace it ?
[Galaxy S 4 Mini General] llapao:
So just flash latest modem, if possible flash ROM without GAPPS. Then check battery. After that you can try batterystats app with your choice of gapps.

System update service from Google is located also in the framework app. One trick that worked with me was to install "disable service" app and disable and then enable system update service both from Google services and framework.
[Galaxy S 4 Mini General] ym58:
three questions :

#1 what is the "LATEST" modem ref ?

#2 flashing modem "WITHOUT GAPPS", what do you mean ? ... the modem does not come with embedded gapps ... !

#3 what is "FRAMEWORK" ?
[Galaxy S 4 Mini General] Loulou-13:
modem and Gapps are totally different !!!

Gapps ,it's the play(store ,play-service.......and many apps signed "google"

the modem is a "sort" of program who manage all the network (2g/3g/4g .....and all variants optimised 2g+(edge: E) , 3g+(H+) ,4g+ ) and the WIFI too , between the hardware and Android system .

===> [MENTION=492129]llapao[/MENTION] want to say that the best way to try a modem is without Gapps because that exclude ALL eventuals Gapps problems ( the first responsible of majority of drain battery on android system ).... for to have a precise result of battery stats.

"Framework" are scripts useful for working of android system .......and google apps/services for the "framework of google services" one
[Galaxy S 4 Mini General] ym58:
Yes I know that of course ... actually, what I did not understand is that llapao suggested that I had to UNINSTALL the gapps before flashing AND testing a newer modem.

Is that correct ?

And, by the way, what is the latest modem ref and where can I DL it ?
[Galaxy S 4 Mini General] Loulou-13:
as i have said : it's just for to test the battery-life !!!! ;) if you want to test a modem...... just for testing.

he never have said to you that you "must" .........
[Galaxy S 4 Mini General] FastGas:
you can do it, you have to flash 2 times consecutively the modem package you need, attention in the package must be 3 files: NON-HLOS.bin rpm.mbn tz.mbn

hi friend iam at THE MODEM (i9195XXUCNK5 modem).i have a bad coverage and signal..so any syggestion for a good modem (good battrey and good signal (3g+wifi) please
[Galaxy S 4 Mini General] :
According to your profile you live in Fes, Morocco. The modem you are now using is suitable for Europe, more specific Austria, Belgium, France, Germany, Hungary and United Kingdom. Living in Morocco you need a modem with JP instead of XX (with XX and JP being the region/country code). I've googled a little, but it seems it will not be easy to download a flashable modem suitable for Morocco. If you cannot find one and if you are using a custom rom, the best option is to restore your phone with the latest Samsung stock rom for your country and reinstall the custom rom afterwards. If you have a European S4 Mini with Samsung stock rom, it's possible to flash it with a stock rom suitable for your country but that's a little bit more work. (google around a bit or search this forum and you should be okay). Good luck!

[Galaxy S 4 Mini General] :
On this page (http://www.mrcrab.net/stockrom/gt-i9195.html) you can find a whole bunch of stock roms (Jellybean and KitKat), suitable for different regions/countries. If you have the time you could experiment a little, to see if one of the roms gives good coverage and battery life.

Very n00b question: I have i9195ububna2 modem, what version should work for me? Have no idea about the nomenclature. Thanks
[Galaxy S 4 Mini General] Freddynic159:
your modem (I9195UBUBNA2) it's in a ROM with bootloader v1, so you would need to flash a ROM with bootloader v2 to use more recent modems.

You also need to flash a modem that is compatible with your same region.

I9195UBUBNA2 = UB = Brazil and probably Central and South America.
[Galaxy S 4 Mini General] jarayama:
So I have to look for specific UB modems? Have looked for it and can't find them, not easily at least.

I have lollipop 5.1 with custom recovery but the cell connection is working very bad, not able to connect to data, not receiving calls, etc.

Edit.: saw up to this post a UB modem file, will try it, thanks
[Galaxy S 4 Mini General] Freddynic159:
Do you have lollipop 5.1 with I9195UBUBNA2 modem? ... then you probably have bootloader v2.

Install

Phone INFO Samsung

from Google Play and check your bootloader version on the

Firmware INFO

section (probably need ROOT).
[Galaxy S 4 Mini General] jarayama:
Thanks for your reply, strangely it says: bootloader version: I9195UBUBNA2

Nothing about v1 or 2
[Galaxy S 4 Mini General] Freddynic159:
Try flashing again I9195UBUBNA2 modem and check if it solve the connections problem.

Unstable Signal

Hello , everyone.

First I want to ask forgiveness for the bad english , I'm from Brazil and I'm using google translate .

I bought the galaxy s4 mini recently, but not until then could not use , the device is always unsigned , and when it eventually appears sign can not use , the signal is very unstable.

I tried several ROMs , I found in national sites and blogs, but without success.

Can anyone direct me to the rom or baseband most appropriate , please? I am with the phone more than a month and I can not use it . :(

[Galaxy S 4 Mini General] Loulou-13:
"maybe"

i have the solution of your drain battery problems .......... :confused:

at the begining of the flash ,we have older google apps version ( principaly the "play services" ) and then after that they are updated automaticaly but thes latests versions are too heavy and real shi* !!! ( :mad: ) and known for battery-drain (umpredictable behavior ! )

===> the firmware begin to suck as hell the battery !!!
[Galaxy S 4 Mini General] sasank360:
I almost never use play services. After flashing gapps I use titanium backup to freeze playstore and gms. This way the apps that need g-apps still work as "lib" files are present.

Also my issue is purely hardware related. Earlier I never had complaints about battery life, even with playstore and an account. But now with/without gapps, any ROM, any modem I am facing drain. Which is due to "Cell standby". Last thing i need to do is to change the SIM card to see if it makes any difference.

But yeah you are right... newer 'play services' drain more battery and are resource hogs. :mad:

[Galaxy S 4 Mini General] simosm:
I had some sudden battery drain on CM12.1, and what I found was because of high usage of "dex2oat". After search I found this can be because of lollipop recompiling some app. Removed last 2 apps I had installed, Viber and Skype and dex2oat CPU usage has gone down. So it was one of these 2 causing my battery drain, now back to normal..

If you have one of these 2, maybe worth giving a try to remove and check if battery drain is still there
[Galaxy S 4 Mini General] sasank360:
Thanks for the advice. But I am absolutely sure my case is a hardware problem. While in flight mode the battery drops by not more than 1% in 8 hours.

When not in flight mode it drains heavily. Atleast 2% every hour. I tried everything and still the symptoms persist. So I concluded some hardware fault.

It was not this bad when I bought the phone. From the past 30-35 days this drain is present. :(

[Galaxy S 4 Mini General] batja84:
sammobile.com there you can download firmware, than extract modem files, than pack them in tar-archive, than you can update your phone with your self made modem update. If you have no expirience, than you can download it here. I make modem updates for myself and just share update files with others. You have only two ways make it yourself or use result of work other people. There is no third way. And of course there is no OFFICIAL SAMSUNG MODEM UPDATE. Forget about it. Or use original ROM, than you phone (maybee) will get modem update with firmware update. :cool:

Hi,

I have the UBMJ7 modem. Why should I even bother with modem updates? Are new modems always better? Also are XX modems good for every European country?
[Galaxy S 4 Mini General] john-soda:
This was fast! Thanks for the answer!

Do you know who is the operator/owner of the website Sammobile? When I search on whois for sammobile, it looks like that it's not a website hosted by Samsung.

I'm only worried because, there is no way to find out, if the firmware packages are manipulated?

What is the safest way to upgrade the Modem, (save means in this case to be sure to have an not manipulated package) with Cyanogenmod installed on the device?

Is there a more detailed Tutorial on how to make his own modem zips?

Or is really just copy a Modem folder out of the Firmware and repack it with tar as a zip archive?

Thanks in advance!

John
[Galaxy S 4 Mini General] sasank360:
Sammobile is not official samsung site but they host all official firmwares.

Do not worry about corrupted firmwares. If your download is uninterrupted then there will

be nothing wrong about those files.

You cannot make zips for modem. Modems can be flashed and written only via bootloader.

[Galaxy S 4 Mini General] sasank360:
You can extract the modem you want manually. If you have linux os it is easy to do.

But with windows you can use the little program that I attached. I found it in galaxy s4 forum.

And I can confirm it works.

Download the firmware of your modem choice from sammobile.com

Extract the firmware zip to get a "tar.md5" file.

Extract the program i attached below and place the firmware tar.md5 file in the

extracted program folder. Open the bat file in that folder and choose the options to extract the

entire firmware. Then go to the "parts" folder and delete every file except "NON-HLOS.bin" , "RPM.mbn" and "TZ.mbn"

Then go to the bat file and choose "make tar" option. After it is done choose "add md5" option.

Then in the "packaged" folder you will find the modem "tar.md5" file. It can be flashed using odin.

Also please learn to trust other members. We are here to help each other.

[Galaxy S 4 Mini General] sasank360:
My observation is, there are certain combinations of modems and google play services that drink your battery in 5 hours.

We must patiently look for the gms service version that drains least battery. Yes i agree it is a painstaking process but that is

one good solution. Sad part is google still does not acknowledge the bad code in many gms service versions.

Some kitkat modems must be avoided. For me newer ones (not from last 2 months) were terrible.

Just flashed the coe4 modem posted by [MENTION=4431484]batja84[/MENTION] . Will come back with my experience.
[Galaxy S 4 Mini General] batja84:
I think, this time I have a little bit faster battery drain comparing to earlier modems versions. But I'm not sure. Maybe this is battery problem, because before update something was already wrong. About 2-3 weeks ago I've installed google now again, it can be reason for faster battery drain.

Hi everyone!

This is great forum about modems for i9195.

I don't understand why I have so fast battery drain on mobile data (3G/LTE..) I have new battery and I run only 2 hours of power screen in half of day. Or just 5-7 hours from charge.

Ok when I switch data off and run on wifi - that's little better.

But this is not the results when I have thi mobile as new. With original Android from Samsung in version 4.2.2 - In this times I get 5 hours of screen in wifi and about 3-4 hours on data.

Or one day with sometimes usage of data.

I tested a lot of modems, best was on 4.2.2 XXUBML4, but than I had CM 11 and now CM 12.1 and on this roms I must need only KK modem.

Or is it some way to ger UBML4 on CM 12.1 ?

What do you mean? where is issue?

And my opinion...

Every newer modem from Samsung will be worst for you battery (because logically Samsung need in order people throw S4 mini and buy some new model... huh? :)

Really I tested and last modem COE4 was terrible on data only 1,5 hour of power screen and 5 hours per day!!!
[Galaxy S 4 Mini General] Royal Ranger:
I am using XXUCOC2 which is working almost stock like with cm12.1 07/04 nightly. I get about 4 hours of screen on time (average over the last month) with mixed WiFi and 3g use. My battery is the original and about 2 years old now.

Maybe just try that modem and see how it works for you
[Galaxy S 4 Mini General] heget:
Well I tested right now.

But I have more questions, when I flash the modems via last Odin I don't wipe cache. It's ok?

And wha about booloader version? I have UCNK5, is there some conjuction with CSC and PDA ?

Ehhh seems to be little bit better 66% battery and 1:30 hod on screen. But only on Wifi ...

Thx for reply ;)
[Galaxy S 4 Mini General] RuffBuster:
Personally on a 3 month old device with Lollipop 5.1.1 on COE4 I'm getting 4 and a half screen on and get thru an entire day, more if I don't use it as much, maybe 2 days. Not sure because I use my phone A LOT. All this is with mixed WiFi and 3G with mixed signal strengths. And usaually at half brightness. Not a lot of gaming, just a little Hay Day.

Been using a lot of different modems and haven't noticed massive changes in battery, just call quality. I find later modems have better voice quality and loudness for the recipient of the call.

[Galaxy S 4 Mini General] heget:
Really I don't know where is the problem... Maybe I have a old SIM card on T-mobile.

Because look on this screens with WIFI ok, but after 50% of battery I switch to mobile data and BOOM only 30mins of screen and 1-2 hours go to less 15% of battery it's incredible really.

I have a clean install of CM 12.1 latest version. Wha do you mean? SIM ? ...

[Galaxy S 4 Mini General] RuffBuster:
Your standby seems to be OK. Though your phone wakes occasionally when screen is off. 3G is always a lot more heavy on the battery, but maybe yours is a little higher though screen on time diminishes over long standby times compared to non stop screen on time from a full charge. What are you're CPU frequencies like over this usage? Maybe the modern your using had to work harder in the area your in, maybe? Notice your GPS kicks in on 3g. Are you using your data connection the whole time your on 3g, watching YouTube or something? Are you 3g or LTE?

It's always hard to pin battery drain down for certain.
