Z5 E6653 static noise when screen is off - Xperia Z5 Q&A, Help & Troubleshooting

I had this problem since I bought the phone last December. The first phone I got had the static noise when the screen is off, so I got it replaced. The second one had the same issue but it kept restarting so I got it replaced again. Third one I got still had the static noise, but I decided to keep it, since its the third phone and all three did the same thing. does anybody experience the same issue?
my battery also only lasts a day, with only about 2-2.5 hrs screen time. most of the battery drain comes when the phone is on standby, it drains like 5%/hour overnight or whenever im not using it. Video is quite old, and I now have android 6.0.1. battery issue is still there, still drains pretty quickly. phone is stock btw.
Here's the video link
another weird thing is that, if I plug a 4 wire audio jack(with microphone) and not connect the other end to anything, it doesn't detect it. is that normal?
it could be looking for loops in the jack to detect a connection but, just want to know if its the same for everyone.
Lastly, if I put a normal 3 wire audio jack, it fluctuates in detecting if there's a headphone connected or not. here's a video on how it does it

[Q] Problem: phone dies randomly, sometimes for days...

Hi all,
I would really appreciate some help with my issue on the HTC One S. I've been looking for a solution for weeks now and still don't have a clue on what it could be happening.
The PROBLEM is this: sometimes my One S turns off suddenly. Next, I turn it on but it is very likely to do the same again in a few minutes. If I am lucky, it turns on and works for a while (which can be from hours to days), but if I'm not, the phone is completely dead (not even responding to charge and no matter how I try to boot it) for hours or even days. Finally, I get it again to life when I see it starts charging the battery (always from zero... even if it died at 80% battery).
I had a video on youtube to show you what it happens. What a pity I can't post it here cause of xda-developers rules!
Do you guys have any idea if this could be a battery issue/software issue or anything else?
Additional information:
-Glass is broken (phone works perfectly) but didn't have this issue for one month since the incident.
-Phone has been working now for 2 weeks (it will do it again... I'm quite sure)
-I dropped the phone into the snow a few days before it started to act like this, but dried it quickly.
Sounds like faulty battery or faulty battery connection. That would require opening up the device and either replacing or reconnecting the battery.
Thanks, it is always good to have a second opinion, two minds always think better than one
Just in case anyone else would like to give his opinion, this are other (maybe) useful symptoms: phone reboots in the middle of the night, or, if already turned off, it turns on (and off again sometimes) by its own. Also, sometimes, just before turning off, screen freezes for 1 or 2 seconds. The phone has its bad and good days (thankfully good days are more frequent as time passes), but, in its bad days, it turns off many many times and sometimes it doesn't even completely reboot, I just see first screen then nothing.
Also I have been using car chargers not from HTC in the same while the phone used to have this behaviour (like the Kindle car charger). Actually, once, while using one I bought on eBay, I got a message saying something like "phone has been disconnected from charger to avoid damage".
What could this mean? Battery fault can make this? I appreciate any similar experience or opinions
Bateries are durable now days, I'm afraid that the snow got into your phone and caused a short circuit on motherboard.

Nexus 5 suddenly shutdowns cold on its own

I had the Nexus 5 since launch and its been working fantastically well until it suddenly shuts down by it self in the last couple of days now
As soon i start the camera app, snapchat, watch you tube or listen music (with screen off). The phone goes blank, shuts down and refuses to boot back unless i plug in the mains usb cable which is absurd as the battery was around 60% and clearly there was enough power left. Strangely the phone forgets all my saved wifi passwords and have to connect manually each time the phone shuts down.
I have tried all assortment of troubleshooting methods such as upgrading and downgrading from KitKat to Lollipop , cleared the cache and running though safe mode and calibrating the battery but the problem stills persists
I did replace the screen back in November 2014 and it was work fine until this week.
I have opened the back casing and checked for anything that might be loose but i cant see anything wrong with the components.
I believe the battery is failing and want to know if i can resolve it from any other methods i haven't tried yet. I will be ordering new battery for nexus 5 and see if it solves the problem.
You might have punctured the battery when removing it when replacing the screen

Galaxy S6 keeps turning off after being dropped into water

Hi at all,
about a week ago my girlfriend dropped her Galaxy S6 into the toilet (NEVER put your phone into your back pocket).
After some days of drying I was able to turn it on while plugged in and except for the battery everything worked. I replaced the battery and everything went back to normal. Sometimes the battery wouldn't charge over a specific level and sometimes it just turned off but since yesterday it keeps turning off as soon as I can see the lockscreen. If it's plugged in it stays on and I can use it as always, everything still works, but it's basically impossible to use it without a charger
What could be wrong? How I can identify the source of the problem? Is there a log I can use or some diagnostic tool?
Thanks a lot,
Thomas

Did you use an oem battery? If after using a genuine Samsung battery you still having issues, it may point to the charging part of the motherboard.
The battery I bought was sold as "official" Samsung and it looked exactly the same. I also didn't buy the cheapest one so I guess that's fine. I don't think that it's a problem with the battery since the phone boots up until the lockscreen appears and then shuts down. If the battery was dead it would crash at any random point and not always at the exact same time. The overall behavior is pretty strange since it stays on and works perfectly fine as long as the charger is connected.
So is there a log I can search through? Mayber there's some kind of low voltage warning or something like that. Otherwise I'd have to sell it as a defect device on ebay and I would rather like to keep it

Pixel not charging

Bought a pixel on eBay and it was working a bit. Screen sometimes goes static and random reboots and shutdown. Earpiece and speaker works sometimes. I had ubreakifix replace screen and battery and now it doesn't charge. When they returned it showed 17% and shutdown and no longer noots. Computer doesn't recognize the phone. Any help?
Did you contact ubreakifix? Maybe it's covered by warranty if they changed the battery, and now it does not charge. Especially if you tell them that the phone was able to be charged before the repair.
I got similar issues with my phone like those you had:
Sometimes the phone freezes, then the screen flickers shortly, then it's off, after a few seconds it reboots. Do you think this can be caused by a weak battery?
Thanks in advance.

Samsung T295 shuts off unexpectedly - Battery mod

Hi all,
I have modified my T295 to run directly off of the 12V in my car.
Basically I got a Buck LM2596 3A Step Down converter and dialed it in to exactly 4.0V to mimic a almost fully charged Li-Ion battery and hooked it up directly to the battery terminals, skipping the tiny board that comes with the battery. In other words, straight to the mainboard.
The tablet works perfectly as a car stereo connected to the Bluetooth Amp and doesn't have any problem, but once every 3 days or so it suddenly shuts off. Sometimes I enter in my car and it's already off and sometimes I'm driving, it suddenly gets a completely black screen and then shuts off. I can turn it on immediately after, but sometimes I need 2-3 tries.
Maybe it's kernel related and triggers some sort of brownout? But this doesn't make sense to me, since I can stress it and it doesn't turn off.
It's Android 9, rooted, debloated and decrypted in case this helps
Thanks for any advice!
