Xperia Z3 Plus problems.

[JoshuaMaurer]

Dear forumusers,

Since 1 month I am a owner of a Sony Xperia Z3 Plus.
I have a couple of problems with the device.

* First of all, the heathing problem. Even while browsing the web, or using whatsapp, the device is getting really Hot (Like it is hard to keep the device in hands as it's getting really Hot.)

* Second the battery drains soooooo fast. When I don't use the phone it uses a lot of battery. Like 5-8 percent per hour. Which I don't think is normal when the screen is off. Not even talked about the battert drain when my mobile data (LTE) is on. Then it is getting absolutely horrible. That when I litteraly have a 3-4 bar connection.

* Also I mention the screenbrightness is changing over time (no I don't have the automatic brightness thingy on)

I have to mention that I got this device for free as it was a showmodel in our local phone shop. Could a reset fix these issues? Or maybe trying to repair the phone with PCC?

Thanks for your help.

Boot in >>> safe mode and check again, as for the LTE bands, settings > about phone > status > signal status 

what do you see?

If the phone heats up, the screen will dim

Hey JoshuaMaurer, I agree with uliwooly, try the Z3+ in Safe Mode and see if that improves anything. For your first point with the phone getting hot even when you're just browsing the web, there's a chance it could be the CPU as the Snapdragon 810 was well known to get VERY hot even when not doing demanding tasks. I hope this helps.

Thanks both for the tips. @uliwooly when I check my signal strength it says the following: -83dBm 15 asu. I live in the Netherlands so I honestly have no idea if it will be the same in other country's. Some extra information about the LTE wich I forgot to mention is that sometimes when I have a solid 4 bar connection, it drops down to 0 bars for around 30 seconds. I think this is also happening when the screen is off which is causing the horrible battery drain. Any ideas on that?

@JoshuaMaurer

Signal Strength  

-67 dBm	Minimum signal strength for applications that require very reliable, timely packet delivery.
-70 dBm	Minimum signal strength for reliable packet delivery.
-80 dBm	Minimum signal strength for basic connectivity. Packet delivery may be unreliable.

As you can see, the problem is network coverage, which will drain your battery faster and it will heat it up faster.

Do you know any solutions for this?

@JoshuaMaurer

That's entirely on your carrier, perhaps they have some down towers or they just have bad coverage in your area.

I have the exact same problem with usb  today  but it was working ok a month ago still on Android marshmallow

Did you manage to solve it?

If the signal is weak a temporary fix is to switch to 3G and see how that helps the battery.
