Battery drain after saving activity

I know that this a known issue and I would like to confirm that on 3.56b, still exists. Today after trail running for 1:22h I noticed that the F5+Ti used about 10,6% of battery. I had: music on with bt headset, phone connected with many notifications, wrist hr on, map on and live segments. So far so good, the consumption is logical. After saving my activity, the battery drained 6% in 1,5h and continued to drain. After 7h the battery was 15% down. Something is still running in a loop after saving an activity. I have reported this to beta team by email.
