GALAXY NOTE 4 BATTERY DRAIN, OVERHEATING, AND SLOW PERFORMANCE PROBLEMS

 GALAXY NOTE 4 BATTERY DRAIN, OVERHEATING, AND SLOW PERFORMANCE PROBLEMS

Roughly two months my Galaxy Note 4 has began to overheat and the battery to discharge too fast. After a time it has began to reset and become slow (especially when opening programs). I had bought a new battery and made a Hard Reset, not restoring the backup Gmail or Samsung. In other words, it was like it came from the factory. After this procedure the problem has persisted.

Currently it is working under stock ROM 5.1.1, not rooted.

Hence, through the bootloader, I ran a factory wipe and cache wipe and again not restored the backup system avoiding to import some “junk”. I was careful to remove the chip and the card (which was not reinserted), and remove background apps from the home screen, such as clock, and turn off 3G and Wi-Fi.

In the first moments it had worked without problems, but when I enabled 3G to gradually upgrade and install the applications, the issue came up again. The first application to be installed was the WhatsApp. But also I tried this procedure first installing Swype keyboard and the problem occurred, so I could not associate the problem to a specific application.

The fact is that even after these procedures the problem persists. I’m barely managing to use it in view at all times lock and reboot, or even be frozen for minutes before unlocking, whenever I try to open a new application.

After enabling some attributes in Developer Options in the About Device menu, I could retrieve the following error messages:

“Unified Daemon is not responding”

“IU of syst. is not answering”

Among some other specific applications

I have seen this problem to freeze the opening of applications on desktops with little swap memory. But there seems to be the problem since I am taking up only 184MB of cache.

There are moments when I can open applications and perform processes for some more time before locking. At other times, then hangs start and just taking the battery and restarting to go back to work.

I has turned on in Safe Mode but it seems that problem persists. — Andre

Solution: Hi Andre. If the issue is software-related, it should have already been fixed by doing a factory reset. An app-caused problem should also fail to occur when in safe mode but it looks like that’s not the case.

Persistent overheating and fast battery drain issues can also be symptoms of a motherboard problem. We know that you have done almost everything in your power already (like using another battery or doing the software solutions) so there’s high likelihood that the problem is caused by something that you cannot fixed. Based on your problem description, it looks like you haven’t actually addressed the problem because nothing changes after doing all the stuff you did.

We recommend that you consider a general hardware checkup, or even a motherboard replacement if the symptoms continue.
