Immense battery drain!

[johnCforVTS]

Hi, the last couple af days its really a downhill for my device, other than the fact that my camera doesnt flip at all, and i am planning to visit asus sevice center the next days...battery started to drain like crazy too. And i am using the device wayy less in comparison with other days. I fall asleep with 80 and i woke up with 40%. Nothing has changed yet i am in a constant hurry to charge my phone which by the way is charging way slower than it used to!
Anyone else something similar?
Thanks in advance

I dont think that is any of the apps the issuse because i didnt add any new the last month at all. My device as it is one day out of the blue just started draining the battery. No i didnt try that safe mode solution... i dont know what it is but maybe I should look it up. I dont have much free time to spare on these things. Its a 3months old device and its like i have a 5 years one for crying out loud.

I've begun Safe Mode test. Will report my result once I get them.

Update: In Safe Mode battery was used very sparingly. Then I rebooted my phone into normal mode and disabled SIM card. Again battery was used very sparingly. So it isn't an app, its cellular network.
I will run further tests and try to see what part of cellular network is responsible for battery drain (battery is discharging fast even at night when there are no calls/SMS messages and I'm on WiFi).

Did you only disable SIM card or WiFi too? I've heard about users with battery drain that eventually realized that they had a device on the network that constantly pinged the phone.
If it's your cellular network, then you must have a really poor signal so your antenne constantly runs at maximum signal boost
I will send you instructions on how to log your device

I've only disables sim-card. WiFi was still active. It looks like the battery keeps draining if I disable 4G. It also looks like the battery keeps draining if I disable mobile data transfer.
I will capture logs.
