    I have a Galaxy note 4 and its been like a year I have had it. The battery now goes from a random percentage to zero. Does anyone know how to fix this?

    Most likely your battery is going bad. Seek a replacement, either OEM or aftermarket. Personally I like the ones from Anker but there are other options out there I'm sure.

    I was having the same issue for a while. The only thing that fixed it was getting a new battery. I got an anker replacement battery. Actually 2 of them plus a battery charger for $28.00 on amazon.

    The battery has done what rechargeable batteries do over time; go bad. Get a new battery.

    I was experiencing a similar (though not as drastic) problem with my battery depletion as well. There's a pinned thread at the top of the forum about battery issues and I found this post in there:

    I have never done this before and had to look up how to do it.....like this, I found on Verizon..... Boy I hope I don't mess this up! This won't void my warranty will it?Wipe Cache Partition - Samsung Galaxy Note® 4

    [Device-Specific Instructions]
    http://scache.vzw.com/kb/images/common/caution.gif Performing a wipe cache partition removes any temporary files that may be causing an issue with the device. All personal files and settings are not affected by this option.

    1. Ensure the device is powered off.
      http://scache.vzw.com/kb/images/common/linote.gif If the device doesn't respond to input, remove then re-insert the battery.
    2. Press and hold the Volume Up button (located on the left edge near the top) and the Home button(located at the bottom in the middle).
    3. While continuing to hold the Home and Volume Up buttons, press and hold the Power button (located on the right edge) until 'RECOVERY BOOTING' appears in the upper left then release all buttons.
    4. Select wipe cache partition.
      http://scache.vzw.com/kb/images/common/linote.gif Utilize the Volume Up/Down buttons to highlight and the Power button to select.
    5. Select reboot system now.
      http://scache.vzw.com/kb/images/common/linote.gif Option is highlighted, utilize the Power button to select.
    I gave it a shot and I've got a very noticeable improvement in my battery life. With your battery going from 50% down to 0, I'm sure that you'll need to buy a new battery sooner than later, but maybe this would work as a short term fix and give you some improvement while you wait for a new battery to be delivered.

    5 months ago, my battery would drop from about 17% to 0.

    Or, the battery status would say 22% (visible when charging), but I couldn't turn my phone on.

    A few weeks ago, it got worse by saying the battery was at 27%, but still wouldn't stay on.

    Replacing the battery helped, now it works well.
