    Question Note 8.0 Overheating and battery drain after KitKat update.

    After updating the Note 8.0 to KitKat it is overheating and sucks the battery dead pretty fast. Does everyone have the problem?

    Yes, everybody seems to be having this problem with the Note 8. Its been reported on numerous websites..

    I took my Note up to Best Buy and even had them flash the O/S and put the lastest factory O/S on it, but it still overheats randomly and the battery life is non-existent. So there's no fix, and the Samsungs guys at Best Buy were insistent there is no problem. All of us who bought a Note 8.0 just learned a valuable lesson - don't ever buy a Samsung tablet!

    ps when I say overheats randomly, I mean it will even oveheat when writing a note with the wifi off and no SD card in the tablet. Good to know that KitKat can't even handle a text editor program - what a piece of sh%%!

    Have you tried booting into Recovery Mode and wiping the system cache partition? I think the steps for the Note 3 should work for the Note 8.0: Reset: Samsung Galaxy Note 3 | T-Mobile Support. This is always a good thing to do after a major system update, since it "clears the cobwebs" from the temporary data cache, so to speak.

    I bought the Note 8 a couple weeks ago and absolutely loved it. Then I installed the Kit Kat update and since then the device is nearly useless thanks to this overheating bug.

    I have tried just about everything short of rooting it and flashing Jelly Bean back on to no avail.

    It isn't normal that the OS tells me my device is overheating when I'm running only basic background apps plus maybe Evernote or checking email.

    I've been particularly concerned that despite noticing that a lot of other people have been having the same problem, nobody appears to have found a solution or reasonable work around.

    Samsung has clearly messed up by releasing this update without bothering to test it. I certainly hope they patch this soon or that someone figures out a fix.

    I did not have either of the problems after upgrading...however after installing Dolphin Browser I experienced overheating once...after un-installing it nothing has happened so far...
    but I believe this upgrade sucks

    I am having the same problem on my Note 8. But I have found a simple solution. I realized it was only having the overheating shutdown issue when I used the tablet on battery power. It is clearly not even overheating, since it would happen after just a minute of use, it just thinks it is overheating. Whenever I used the tablet with an external power source, I never have the problem. The simple solution was to get an external lipstick charger. I found a great one on Amazon for around $10, and whenever I need to use the tablet without having issues, like at work, I just plug in the lipstick charger and I'm good to go, no overheating ever. I figure this is a simple fix until the next android update, when hopefully this problem will be corrected with a bug fix.

    i think its just to do with the nature of the device itself. If your going to use it heavily its going to overheat, bear this in mind its 1.6ghz quad core thats 1.6ghz x4 and a 2gb ram.Using all this in 1 go will corse the device to overheats especially when it has no internal cooling fan not even an air vent for the device to breath. What i do during summer when the device gets dangoursly hot is put it inside a freezer bag and place it straight into the freezer and wait for about 7 to 10minutes. This is the only way your going to cool your device down. Think of it as a microwave in a opposites sence.

    All I can say is WTF were Samsung thinking, who runs their quality control department? All I can think of is that there is some little **** in that office who doesn't give a fcuk about service or quality, just numbers and money. They are a sign of the times of what happens when people who are raised with no principles get into business. They will just screw you over for cash.

    I hope that there are still some old school boys who still work are Samsung who take pride in what they do? As this ****ty product and service will not do. All I know is I have bought 5 Samsung devices in past 4 years and now will never ever touch another Samsung product again.

    Long may they live with what they have made out of me so far, me and samsung just broke up. Thanks for reading my rant, my note 8, when I first got it in January, was great till the update. It has been like living with a sexual transmitted disease every since and there is no cure

    Those who have issue of battery or heating with Kitkat update. Please do "wipe cache partition".it will remove your background junk. How you will do? >turnoff tablet
    > press Menu button+Volume up+ power button.
    >when see Note 8 logo,only release power button.
    >then select wipe cache partition

    I now have a battery life. Down to 73% with heavy use. I would have hit the charger by now. Take off the back and disco the battery for a couple of hours. Recharge and enjoy. I have tried all the rest but this worked.
    factory reset, calibration and cache. Disconnect.

    I believe "disco" is just short for "disconnect".

    Here is a snapshot of my battery charge time via GSam Battery Monitor app. Here is the info from the chart.

    Note 8.0 Overheating and battery drain after KitKat update.-samsungbatterychargechartupdated.png


    Battery charge was at about 4% at 8.15am when I plugged the battery in for charge. Around 9.20am the charge was about 28% (~10% every 27 minutes...which is about 4.5 hrs for full charge, inline with what various tech publications claim for Note 8.0). Then the interesting thing occurs. The battery charge then instantaneously shoots up from 28% to 100% (fully charge). Does this clearly indicate there is something wrong with the battery? I am only getting 2 hours of full video play time which is significantly less than 8 hours claim by the same tech websites referenced above. The 8 hours may be with airplane mode, but i don't have many apps that are really pulling much data in the background. So the diff in the video play time with airplane mode on and off shouldn't be that different.

    Any thoughts? Thx

    Posted this on the other thread about this issue--I was having same problem so I ordered a new battery. Installed it and something was wrong with it--trouble powering on and when it did, it gave me a weird reboot screen I had never encountered before. So, I put my original battery back in and now I'm getting GREAT battery life! Don't know why this worked but it did. Made my almost 2 year old tablet feel new again!

    Isn't removing the battery the same as letting it drain completely? I let it drain completely and kept it that way for several hours. It improved from 1 hour of video play time to about 2 hrs of video play time. This is still significantly below what it should be. I am going to send in for the service. Thx

    Apparently not the same because I also drained the battery before I did all this. Now my Note lasts all day even when in heavy use. Again, I don't know why this worked for me but it did.

    It probably reset the battery charge information the tablet was storing and it now correctly knows when the battery is and isn't low.
