Q: rMBP 2015 Wake Reason: ARPT (Network)

Got the same issue. I put my 2015 MBP to sleep at 99% charge and woke up with 24% battery remaining.

pmset -g stats

Sleep Count:596

Dark Wake Count:595

User Wake Count:3

turn off the wifi before sleep and every thing gonna be fine in the morning

I know this is going to sound stupid, but I was having the exact same issues. I did try the "turn off wifi trick", which did help, but that process is annoying to me. Then I decided to fully shut down the Mac. I let it sit for a min or 2 off, then fired it back up. 

SInce then then it acts like normal. No more battery loss, even with wifi enabled.

Ive been having this problem too. When I'm connected to my router/wifi, the computer never sleeps, wakes up multiple times a minute, and drains all battery. See a sample below:

I tested to see if this is my router by leaving my Wifi ON, and unplugging my router. It sleeps fine with Wifi ON and router OFF. So its the connection between the router and the computer that is doing this. Still is a bug, hope they fix it!

its a Time Warner Router.

I have the same problems.. wake on excessive wake  3times in a minutes. have u fixed this problems?

No. Apple has given no answers or support either. The only thing to do is turn off wifi before you sleep.

Yeah, but this is only a temporary solution.  Hope the next update will tackle this problem..

Thank u bro

how can get we them to fix an issue like this? seems like there is no way to confirm that they even know about it

Just for visibility, I'm getting the same issue with a 2015 MBP 13". Started immediately after install El Capitan, and is ameliorated by turning off WiFi (which isn't an acceptable fix).

Hope this is sorted out soon.

I started a new similar topic to see if we can get any responses....Re: Wake on Excessive Wake drains battery on sleep

I have this problem on my 2015 12" MB after upgrading to El Capitan as well...

/Library/Extensions delete everything in this folder and its works

I did more research. these files are useful only if you use a RAID device, which i dont.  Also, i DID get another wakeup, but it happened every half hour, instead of every minute.

Hello. I have just bought my Macbook Pro Retina 2015 13' two weeks ago and I also have this issue even after upgrading to El Capitan.

It wakes up almost every minute and sometimes, if asleep for many hours, the notebook gets really hot and shut downs completely. It doesn't wake up. I have to press the power button for 15 seconds for it to power on again.

The best workaround is turning off the wifi before putting it to sleep, however I sometimes forget to do that.

So I created a script that installs and configure SleepWatcher 2.2 to automatically turn off the airport when making the notebook sleep and turn it on again when waking up. Also it remembers if you had the wifi turned off prior to sleeping so it will only turn it on again if it was actually enabled before.

I made the script to be really simple to use, so you can install easily and uninstall whenever you want.

i went to genius bar today and got a fully test. They said its a hardware failure in motherboard, specifically, a so called "temp sensor". So they gave me a motherboard replacement. But i though it was a software problem.  I'm completely confused with this problem. Im not sure if the motherboard replacement could tackle this issue.      My friend also got a RMBP 13 early 2015 and work perfectly with EI Captain.
