I should make this more clear. Apple Mail it self is not the culprit it is the cloud. When I off line cloud Mail goes back to light CPU/battery drain, when I put cloud back on the CPU/battery drain goes up. Yesterday I had to sign out of the cloud and sign back in and Apple Mail was again normal CPU/battery drain. None of this happens in my iMac in 10.8.5 so I think it has something to do with OS 10.11 and the Cloud.


BTW, I have three mail accounts in Apple Mail, Comcast, G-Mail and .Mac/Cloud.

Because Mail and Cloud was using so much CPU it affected battery drain because when the CPU is working harder it takes more power and drains the battery down faster. Also the fan comes on to cool the processor.


If you don't use the Cloud then you probably won't run into this situation. When my mail/cloud are working light, my battery in the 2015 early MacBook Pro lasts for 10 to 12 hours easy and the computer runs cooler.

Charge the battery fully note down hours remaining. The best thing is to create one more user , going to system preferences. Do not give any apple id while creating new user Log out from present user login as different user go to battery icon . See hours remaining it will be quite more than the last user. Logout once again got to original user and see battery percentage. It wll be almost normal hours of battery life and will continue......


Now may battery hours are 13 hours with macbook air which was 3 hours before....


Do write me if this help..........


This is undescribed solution to " Battery draing fast after upgrading to el capitan......

I've had this problem plaguing me for ages. Been to Apple who at first didn't fix it, spoke to the people on the end of the phone and i'd previously looked and a power management log and saw that it was searching for a wifi signal every 30 secs or so - this is with because our wifi dropped off or someone turned it off.. Made a keyboard shortcut through automator to turn the wifi on off with some command lines i found


Re: How to create shortcut to turn on/off Wifi in Snow Leopard


The command lines need to be as follows for Ei Capitan:


if [[ `networksetup -getairportpower en1` == *On ]]

then

networksetup -setairportpower en1 off

else

networksetup -setairportpower en1 on

fi


NOTE: en1 referes to your wifi device, you will need to check what your wifi is, mine was en0.


Turn wifi off before sleeping your mac. Just started this, will be looking at if there is a better way to solve this.

Having bad battery life problems updating from El Capitan to macOS Sierra. "100% charged battery drains fast on Sierra for 2 - 3 hours only. Before the mac OS Sierra upgrade, it could stay for 8-9 hours,".
