Like most of you I was prompted with the 4.3 update starting about 3 weeks ago. I decided to finally update the device, which is now about 13 months old.
When the device booted up I had an incredible amount of battery drain (50% an hour) and I had absolutely no ability to turn on my wifi. Since sprint service anywhere near my house is abysmal I need to be able to access my wifi router to do anything data wise on my phone.
I contacted both Sprint and Samsung regarding this issue. Samsung asked me to do the usual steps of rebooting several times, and finally a full factory reset. Neither one fixed the issue. They told me to take the phone to Sprint or to contact them for a warranty repair if the phone was within the 12 month purchase.
At the Sprint store and on the phone I was told that the only option I had was to purchase insurance and then pay their insurance costs (would have totaled up to $150). This was the only way Sprint was willing to intervene with the phone in any way.
It is unfortunate that because the update that Sprint pushed onto the devices I ran into so many issues, which was complicated by their infuriatingly short sighted "solution", pay them more money to fix an issue.
I always felt that stock 4.1.2 and stock 4.3 really were great ROMs running on the Note II and I never felt any need to run any other custom ROMs for this phone. My solution resulted in me taking my 4.3 ROM and rooting it. I didn't want to root it. After rooting I used a custom bootloader to force a custom ROM onto my Note II. After doing this the battery drain and wifi issues were both resolved. This means there was nothing wrong with the hardware on my phone, and Sprint wanted $150 to fix something that was caused by their software update. I eventually pushed the stock 4.1.2 ROM on my phone which now has the original fantastic battery life and can have wifi turned on.
I am fortunate that I had enough tech knowledge to have custom ROMs to solve my own issues. I feel unfortunate for the countless unknown people who had this issue and were forced to pay $150 to the "insurance" program, when Sprint broke the phone. I also lost many many hours, and of course, all the personal data from my phone in this process.
I'm having the exact same issue on the Galaxy III after the latest update. The battery drains at about 50% every two and a half hours - for a total run time of 5 hours. And that's NOT using the phone! That's when it's just sitting on my desk completely unused by me. No phone calls, no nothing. I imagine if I were actually using it, it might last for about an hour and a half.
My battery is down to 68% in 5 hours and all I have used it for was one short phone call and a few texts. Before the update it would be at least at 80% or more at the same time. I hope they have an update soon to fix that.
Thank you for the reply. A common misconception is that the service provider pushes device upgrades. Device upgrades are pushed in waves by the manufacturer of the device and are tweeked differently for each carrier due to different internal hardware and software configurations. We never recommend rooting the device because many times after after a failed upgrade the result in the rooting process is a failed attemp and the phone being bricked.
Oftentimes an initial push of an update contains certain glitches that are usually quickly rectified by the manufacturer. We recommend speaking to one of the device support specialists before going to extremes. Samsung can be reached via chat at:

Sprint OTM updates are NOTORIOUS for killing battery life. Anyone remember the Galaxy S2 debacle? Made the phone practically worthless. I disable all OTM updates on my phone for this exact reason. I enjoy my Note 2 and what it provides, I don't want any pointless updates ruining my experience. I've been a customer long enough to know these updates rarely turn out well unfortunately.
If you guys want to fix it, do a factory reset and completely wipe the phone. Start it back up and only install up to the last update before the most recent. Than google how to disable OTM updates (you'll need root) and kill it. Your phone will be back to running the way it's suppose to.
I think I found the solution. At least it works for me. Go to Settings/More/Application Manager. Then go to the Running tab. Find a program called DOWNLOADS. Tap it. Then tap, "FORCE STOP". Then tap "TURN OFF"!
Fortunately in this new update, they have TURN OFF. I don't think they had that before. Before I could only stop it - but it would start right back up when I restarted the phone. Now it actually stays off! And I haven't had any problems since.
Likewise, after updating my Galaxy Note II via OTA to 4.3, my battery life has gone from only needing to plug in after 14-15 hours to my phone being almost dead by lunchtime (5 hours). This happened instantly and suddenly after the update was applied, aka THIS IS NOT A HARDWARE issue. Looking at the battery usage section, there does not appear to be any specific app that is responsible other than Screen and System accounting for nearly 75% of the share. I have tried adjusting a number of settings including turning on the battery saver, unchecking the connections optimizer, updating the profile, choosing automatic networks, turning screen brightness down to a minimum, and still the battery drains within 5-7 hours. I have verified that the battery meter is not "uncalibrated" when I observed my phone die almost immediately after reaching the 1% mark. I have not tried a factory reset, but I guess this is all I have left to do. It is really quite a pain to do one when you have your phone set up exactly how you want it and have installed so many apps that worked wonderfully before.
I am also experiencing new lag/freeze issues where the "home" button is unresponsive for almost 5 seconds, random freezes including black screen that last for 15-45 seconds. There is no excuse for an unresponsive system when you have a quad core processor that is more powerful than most desktop computers from 2-3 years ago.
All I want is my beautiful, powerful, dream of a phone back to the way it was under 4.1.2. I really loathe that this software update that really did nothing impressive for me personally has killed my experience.
Thanks for the post, I see you posted on another thread as well. Were you able to get this issue addressed? From my personal experience, battery draining issues may arise from a software upgrade because of certain applications. I've always tended to perform factory resets after software updates and test battery life after installing certain applications. Have you tried steps such as the ones I've done?

Yes I have tried factory resets and it still doesn't help. I had the same problem with my Galaxy 2 after upgrading to Jelly Bean and that is why I upgraded to the Note 2. I didn't think I would have the battery issue. I have tried everything. Nothing works.
Thanks for the feedback on the battery drain issue. When you have it fully charged; how long does it take to get to 0%? Do you consume a lot of data on a daily basis? Do you notice a longer battery life when you are not connected to WiFi?

Hi Michael C.
After it is fully charged depending on use, it goes to 0% after about 8 hours. I was on vacation and I turned my data completely off and my roaming off, location off and without any use at all the battery drained to less than 50 percent over night. I went to http://bit.ly/1elCJB1 http://bit.ly/1elCJB1 that was posted from Sprint Care and followed all of the instructions and it showed that my battery is in good health. It doesn't show any thing unusual that would drain the battery. Before the update, I could use my phone's data, phone and texting all day until almost midnight and still have battery power. Now, I have to charge it constantly.
