N4 dropped in water. Battery drain after replacing daughterboard or software update - Nexus 4 Q&A, Help & Troubleshooting

Phone: Nexus 4 running on CM 11 nighty 2014-12-12
Hi guys, the following happened to me and it's making me crazy:
- Dropped my N4 into the toilet ~10 days ago.
- After the drop my status LED was permanently on. I opened the phone and cleaned it: status LED running fine again.
- Recognize the microphone isn't working anymore
- Ordering new daughterboard and replace it
- Recognize everything is working fine BUT while calling someone I don't hear anything and the called person doesn't hear me.
- Thought to myself: ****, I destroyed the phone
- Doing another upgrade to CM with cache/dalvik wipe: stil no sound
- via web research I see that it's a bug and has nothing to do with me dipping the phone
So I was quite happy but now I have a ****in battery drain all the time as you can see on the screenshots that I took after leaving my phone pretty untouched over night:

Is this a software error? Or could it be a water damage issue somehow?

[Q] Nexus froze during long call - would not boot again

Loving the Nexus 4 (stock JOP40D + root) although I'm having some issues with the phone sometimes rebooting randomly (1-2 times a day)
and today it turned itself off during a long call (after about 45 mins) and would not boot again.
I pressed all combinations of buttons, plugged into the charger and it would not turn on.
Left it aside for a few mins, pressed power+vol and it booted normally as if nothing happened.
I then went to check the battery settings, and noticed a strange gap (screenshot) like the ones I was getting on my S2 after this kind of reboot.
Any ideas of what could have caused this?

Thanks. Could that really be the case though? It didn't feel hot in my hand
I'd RMA it. I'm getting an RMA device for a "faulty battery". Many Nexi have shipped with dud batteries. Not sure if that's your particular issue, but call Google.

[Q] [SCREEN PERMANENT DAMAGE AFTER 5 REBOOTS][Looking for a fix)

Hi XDA, i´m new in the forum, and i just want something of help, i have my G2 D800 for 6 months, always Stock, until i got bored and installed VANIR AOSP Rom, i was watchin' some videos and the Galery app started to Fail, the only solution was reboot, failed and failed again so i reboot 5 times, then the cellphone frezzed with a screen like the TWRP recovery back but without the letters (im givin just an example) then rebooted with some lines on the right side of the screen and never dissapeared ( i left the phone 30 min OFF thinking that was a warming problem), now the problem is that i live in Bolivia, so i'm not Able to get a Warranty Repair, the only thing i can do is identify the problem (with yours help) buy the parts on Ebay/Amazon and repair with a unautorized repair guy here......
Waiting for a soon answer, Grettings to all!
PS: SORRY FOR THE ENGLISH
I really don't know what could be causing it but maybe when you held your power button down you damaged the cable/connector for the display??
Or you somehow messed up your OS with the reboots.
this is the damage
Its exactly like this

[Q] LG G2 - cannot make/received call after a short fall in the water. any advice?

hi everyone,
after almost 18 month of enjoyment it appends : i fall with my phone in the water!
i dried it the best as i can. I even opened it (see picture 1). Unfortunately now it's just half working because it cannot make or receive any call.
Looking carefully to the inside of the phone, i notice a part of the chip is altered (see the Red circle in picture 2)
=> Do you think is the right reason for this problem ?
=> Do you know if it can be fixed and how ?
I also notice that
- the batteries are drain in 7 hours (15 before)
- the phone is hot (temperature)
- the phone reboot by itself
I think those 3 symptoms are a consequence of the cellular services running for nothing (see picture 3)
=> Do you think I'm Right ?
=> Do you know how to dis-activate the cellular services ?
Thank you for reading my post and helping me if you can

Something has obviously been fried. Probably need motherboard replacement that wont be more cheaper than getting a new second hand G2

WiFi and Bluetooth not working

My phone is a Cubot One running MIUI 4.8.29 custom ROM v6. One day, my WiFi spontaneously ceased to work. I thought it was a temporary glitch, so I rebooted. It worked again. Then, it spontaneously ceased to work AGAIN. since then, it had just been off and when I try to turn it on, it just greys out for a few seconds and switches off again. The same thing happens to my Bluetooth. However, twice, randomly, about 4 months ago and 6 months ago, it notifies me of possible WiFi networks. It stays like this for a couple of hours, then returns to the aforementioned state. I have tried a full reset several times with the stock ROM and others to no avail. I've been using mobile data since then. I don't know how this has happened and I am wondering if the altered build properties of the custom ROM have anything to do with it. The WiFi-pertinent ones are attached. Please help - not having Bluetooth or WiFi prevents me from selling the phone. Thanks all!
