    Hello
    I have my note 4 for quite some time now and it recently started to turn off at a very high battery percentage (85%, 80%) and later it started to overheat really quick and turn off. i opened it and seen that the battery got swollen i bought a new one today and after putting it in it happened again but the strange part is that the heat didnt come from the battery it came from the sim and sd card area. Is it happened to anyone before and if so can u advise me on what to do? thank you and best regards

    Welcome to Android Central! Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

    1. The main Settings>Battery screen.
    2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
    3. The Screen category (to see total Screen On time).
    4. The Cell Standby category, if present (to see Time Without Signal).

    You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.

    Also, if you have an SD card inserted, Unmount it (in Settings>Storage) and remove it, in case it's corrupt. A corrupt card (or a corrupt file on the card) can cause overheating (often because the system's Mediaserver is hung up trying to scan the corrupt file).

    Go to Settings>Storage, Unmount the card, remove it, and insert it into your computer. Can the computer read these files? Backup as much as you can right now, then run chkdsk to look for bad sectors: http://forums.androidcentral.com/amb...d-sd-card.html

    I tried running it on cmd and it said no files were corrupt and i tried just for comparrison to boot up the phone without the sd card same problem it works for 2, 3 minutes and it gets really hot and the screen freezes and starting to reboot it again and again so im ending up taking out the battery to turn it off

    Ok--after getting those battery stats that I mentioned above, the next thing to try would be Safe Mode, to see if the battery drain is being caused by some 3rd party app you installed or by the system: https://support.t-mobile.com/docs/DOC-28897

    I think the remaining possibilities are a corrupted firmware or faulty hardware. The latter would require a trip to the repair shop or a Samsung service center (which would probably cost a considerable amount). For the former, you could try reinstalling the firmware using either Smart Switch (SmartSwitch: Install & update or replace firmware) or Odin (http://forums.androidcentral.com/amb...interface.html).
