Really need help with my fast draining phone!

A month ago I posted this thread: http://forum.xda-developers.com/showthread.php?t=1650113
And I still cannot fix the problem. I sent the phone back to repair but it didn't help at all! The repair description said that they did a 'software update'. It took about 3 weeks for my phone to return so I don't really want to do it again. Unless I really have to.
I have tried many stuff to fix this problem:
Bought 2 new batteries
Clean ROM install with NVFlash
Installed different basebands and rils
Formatted the batterystats
Tried different kernels and ROMs (custom and official)
Pulled out SIM/SD Card
Please does anybody know a solution for this problem? I really want my phone back!

Wow your battery drain (Screenshots from your first thread) is really huge. Let's try to solve that mystery together
But there is a chance that your phone really is faulty after all you tried already.
Please insert the original battery and fully charge it.
I don't use stock roms but think you should flash an official kdz first without any custom kernels. V20q or V20s (maybe with flix tweakpack). DONT use titanium backup etc, leave it stock.
You should install battery monitor widget by 3c to get information on your mV consumption.
In your Screenshot your reception wasn't good, please set it to "2g only" for now (or even consider to disable data totally and check how it behaves with wifi only).
Use your phone normally. How is your battery?

Thanks for responding.
I have tried to install the latest firmware with the LG update tool and the drainage was about the same. I did not install anything else on the device then.
Currently I am on the latest CM7 kang by temasek and baseband version v20s with 420 ril (also v20s daemon, I don't even know what this is).
I'll try battery monitor widget.
The reception at where I live is not so good even with 2g only. But I don't think that's the case becuase I tested with airplane mode activated and have also removed the SIM card.
Thanks again.

Just wanted to report that battery monitor widget is showing a power consumption of about -130 mA while on standby.
I think this is a very big number. And I think I had about -10 mA before this problem.

I had the v20s deamon installed too and I also had a pretty huge battery drain.
So my suggestion : remove it (by installing clean rom again).
As Tonyp already mentioned : try to install an original LG rom with it's default BB en RIL (use NVFlash to flash it). Don't use any other kernels or tweaks. Just the default.
Also don't restore anything (for instance with Titanium Backup or other program).
And set your phone to use 2G only, because a bad reception can indeed drain your battery (and fast too !), because it constantly seeks the network. Setting it to 2G only (it's mostly the strongest signal) can avoid battery drains.
And finally try to recalibrate your battery, there are tools available for that in the Google Play store.

Recalibrating the battery is a hoax. At least if you mean to wipe the battery stats (what most tools do). Real recalibrating would be to completely drain the battery (till the 2x turns of - not more! A completely empty li-ion battery would damage it!) and fully charge it again. But that doesn't improve the battery life, it will only improve the battery reading precisness.

Same results with stock based roms too?
CM roms are battery hungry

Yes, I got the same results on stock ROMs. I tried to 'cleanly' install the v10b firmware via NVFlash without installing else on my phone many times. And the problem still persist.

[I9295] Cellular not working

Hey guys,
in the beginning, sorry for my bad english (native german). I have a problem with my I9295 aka S4 Active. Since the update to 4.4.2, my phone gets thrown out of the network. Wlan and Bluetooth is fine. Now I flashed the official Samsung DOB4 firmware. Yes, I've downloaded the file multiple times, and the md5 sum was always right. After I flashed it, I was very happy because my cellular network was working again, I could make some calls, etc. But after 20 minutes, it started again. No network. Well, my IMEI was null, and to fix it I had to root. After rooting, my IMEI is there again (yes, the right one) and everything worked fine and was still working, up to yesterday. IMEI still there, baseband too, everything seems fine, but I can't get network. I have to reboot multiple times to get it working again, after that it's working maximum a day, after that, no network again . Atm, i've flashed CM12, but the error is still occuring. I'm very desperate, I hope somebody can help me.

I have a quite similar problem:
My I9295 loses service randomly. Happens quite often.
When I try to go to Settings/More Networks/Mobile Networks I am told "No SIM ..."
SIM is in and had been active. Phono tells me I have network reception.
After reboot it works for an hour or 20 minutes or whatever it wants to.
Sometimes it reconnects after a while, sometimes not.
When I leave it on during night netx morning reconnect works only via reboot.
SIM reader had been replaced.
Problem persists with genuine 5.0.1, with this one: [ROM][Official Nightly CM12/Unofficial CM12.1][5.0/5.1.1] builds for I9295
and WizCyan ROM.
Any suggestions?
BTW I use a TWRP recovery

Possible reason explained here
http://forum.xda-developers.com/showthread.php?p=56955843
Enjoy

Thanks for the hint.
Not sure if I get this. The problem was also there with the genuine Samsung ROM (lolipop)while the thread talks aout losing modem function after flashing custom ROM.
About previous I am not sure as I bought it used with 4.2.2 on it.
I updated to 4.4 and then 5 OTA, all genuine.
Only because the mobile kept on losing network I switched to custom ROM, but the problem persists.
At the moment I use the Pac-Man ROM 5.1.1 where it seems to be more stable.
Strange!

@augek
The linked thread isn't only about custom roms - you can end up with partly flashed baseband on genuine if you don't power off before download mode and flash using Odin.
Was the replacement job of SIM reader done by a qualified person?

Following your Suggestion i flashed the genuine lollipop with odin. Yes i switched of Prior to flashing.
And Yes the Person Who did the card reader Job is qualified.
Still the Problem persists.
So to me the question is if the Firmware (driver) is the Problem of my sim card. The sim i tried on my s4mini and doesn't cause Problems so far as far as i noticed.
P****es me of somehow.

[Q] "Not registered on network" error. *PLEASE HELP*

Yesterday, my phone just decided it didn't want to be connected to a network anymore. I was running DynamicKat ROM. It just happened out of nowhere and continues today. I've tried flashing different ROMS and they install fine, but I still can't register to a network. I believe I need to update the modem, but I'm not sure. I'm currently on baseband version ANK4, but I think I need to update to BOC4. Does this sound correct? Any advice would be great, and if you might point me in the direction of any files needed it would be greatly appreciated as well. No need to link, but just a general section where I could find the files would be helpful as I seem to have little luck with the search function here. Thank you in advance.
EDIT: Ehhh... Nevermind. It just started working again. I can't explain it. Suddenly I was connected again.

Always a good idea to check your APN settings if you are in a known coverage area with a new ROM. Been my problem 90 percent of the time

Funny you mention this as I run the same ROM and have had this occur to me whilst traveling around my area and in and out of T-Mobile "Dead Spots" which seem to be many...
Even called T-Mobile to report and best they could tell me is go into "More Networks-Mobile Networks-Network operators" and select - Select automatically.
A real PITA when you driving down the road and need to call out or re-connect your call with someone.
Note: I've had numerous issues on different ROMS similar to this so I pretty much blame T-Mobile and their service in my area unless someone else can chime in, I would be curious...

I had a similar problem on DK, except that it was unmounting my sim card completely & I had to reboot to get it working again. Happened every hour or so, very frustrating. I tried a different rom & the issue went away, so it's definitely something funky with DK which makes me sad cause that's my favorite rom.
I just reflashed it last night though & I took the precaution of completely reflashing ANK4 through Odin and redoing root & TWRP too, then flashing DK like normal. So far, so good(and it seems to have fixed the battery life issues I was having as well, yay), so you might try that method & see if it helps for you too. But be sure to back up your internal storage first cause odin WILL wipe it. Learned this the hard way, bye-bye all my pictures & titanium backups :/
Files I used can be found here.. BOC4 is for LP, so you should be fine with ANK4.

Z3 Compact - How to ONLY update baseband (having "sim" loss issues)

Hy guys,
I'm facing some issues with my Z3C. I bought it 2 weeks ago, unlocked bootloader, installed twrp, flashed CyanogenMod 12.1 Nightly on day 3. Updated CM twice with OTA since then.
My problem is that the "sim" card (GSM/LTE) is randomly not noticed by my phone, like if its removed. I checked the sim tray, everything is stable and well seated, the sim is also OK, never had an issue with it. I just have it in my pocket or on the desk, pick it up to do something and there is already a No SIM icon on the status bar, and "Emergency calls only" If I lock the phone. Only a restart solves it.
I could not find any noticeable trigger which would lead me to the source of the problem. Sometimes its OK for 2 days sometimes it happens 2 times a day. The really frustrating part is that when the sim "disconnects" the phone starts to heat up significantly. I usually only notice it because my phone is burning my pocket. Also it looses around 20% battery before I notice it. After the restart everything is fine, the phone cools down.
Went to the Cyanogen forums for some possible solution for the problem, they suggested that I should try to update my baseband to the latest version, and if that still doesn't help, do a full wipe / clean install of CM nightly. I tried downloading the latest firmware using FlashTool and XperiFirm, creating an ftf, and flashing only AMSS_FSG, AMSS_FS1, AMSS_FS2 included into the flash ( I only wan't to flash the baseband ?!?).
My question would be: Anyone else had this problem and managed to fix it somehow? If not, anyone could please help me with a small guide how to ONLY update the baseband of my Z3C (D 5803) running CM 12.1 nightly on twrp recovery?
When I tried the flash above, my baseband version did not change. Currently I'm on "8974-AAAAANAZQ-00005-40" Baseband version, and I would like to move to the latest most stable one.
Thanks for the help in advance!

If it were my Z3c, I would flash back to stock completely and then reflash with Cyanogen. This is a device on which you have the freedom to do that, and that gets the job done safely. Backup your CM install, and then flash everything.

Cant Turned on WIFI/BT, Already Flashed for BT still not working

Hi , its been a year since i bought xiaomi mi 9-global rom(128GB) and all work properly.
if im not mistaken the first rom when i bought is MIUI 10 , then the last time i update if im not mistaken is around september in MIUI 12.02 for the latest security patch.
Suddenly problem occurs recently maybe around a week. where my Wifi & Bluetooth disconnected by the system and cant be turned on but it fixed it self as i restart and now its never fixed.
I already some of fixed below :
- Restart devices
- Wipe all data
- Factory reset
- Try to flash the ROM from official one MIUI 12.02
- Following some tutorials that reset bluetooth and wifi settings
- Try downgrading MIUI version to 11
but still didnt work the Wifi & Bluetooth setting always crash & cant be turned on , try CIE or CIU test found out that the proximity sensor also didn't work.
I also tried some tutorials that do in EDL mode to install persist mode but its not working due to the Authentication it says" i dont have the permission"
Is there anyway i can fixed the Bluetooth & Wifi in this device?? The Mobile Data is still working and other features still working except Proximity Sensor, WIFI, Bluetooth.
Is the only way is to let the xiaomi store fixed it?? this is my only phone so i need it alot and the office store probably going to take long since pandemic.
Please help me Xiaomi Pro's out there :crying:
Edit :
- my xiaomi account already match with the phone the proof is i can unlocked OEM using the xiaomi. But it seems i still dont have permissions to flash EDL.

I think it's safe as miui could be.
But be shure to follow step by step and take right rom version. If it's working you can flash original miui or custom roms.

Thanks for the suggestion, after i tried to flash to EU ROM i got new MIUI version which 12.04 , in global its 12.02. However the problem still happening or still remain unsolved. The bluetooth & wifi still cant be turned on, i tried on CIT it also not working and everytime the i try to open wifi & bluetooth settings , the settings always freeze and crash probably because it error. Is there any other solution you can provide?
Thanks

I think, if you have done a really clean flash with formating data, that it's a hardware problem.

yes, i did i already follow the instructions & having no error at all for the ROM and other stuff except the WiFi & Bluetooth.
But for me its just really weird, my phone looks still great from outside no bend, dent, or crack it never fall as well.
The problem starts occurring by itself like the system is forcing the Bluetooth & WiFi to off then at some point the WiFi is connected but not transferring any data after restart everything fixed then its not working at all, which when i tried to turn it on it will freeze or the system not responding or off by itself.
btw appreciate your answer, i'm still waiting for other solution if possible :crying:

Are you shure that you've got a global version. I had nearly the same probs as I've flashed the global on my eu hardware.

In my personal opinion there're 2 possibilities
Damaged hardware
Or
Modem Partition wrong or damaged
MODEM or RADIO - the phone's radio
Also called baseband, it is responsible for signals and on older devices may control wifi, bluetooth, and GPS (on most newer devices, these are handled by the kernel and ROM). Upgrades are country dependent and may improve or diminish battery performance, network signal strength, and roaming capability. It is also sometimes required to have a minimum Baseband version to use a ROM so that the RIL will play nice with the Baseband.
Modem firmware is a mini-OS for the cellular radio chip which has its own processor. Firmware is a general term, firmware exists for a lot of things on phone. The wireless chip for WiFi, GPS, and Bluetooth often has a firmware as can the GPU core among other things. These firmware files are usually located inside the SYSTEM or VENDOR partition. The modem firmware is special because it has its own separate Baseband Processor (BP) so the firmware is left out of the system image in its own partition.
Modem is not an Android-specific partition. It is tied to the hardware of the phone, but the kernel has a code allowing Android to interact with the hardware. But the baseband processor (BP) - which runs modem and is responsible for all communication through mobile networks e.g. call, SMS and internet - is totally isolated from Application Processor (the one we call CPU) and is not governed by Android kernel; it runs an independent RTOS.
May it helps you for getting a solution....

Thanks for the long and detailed explanation . My mobile network & GPS still work properly without any issues.
but idk if the Bluetooth & WiFi chip maybe fried inside
Maybe i just dont have any other option except to fix in mi store.
Once again thanks for the help :fingers-crossed:.
