After this software update, I found battery issue during poweroff.
I power HTC 10 off every night. Before going to bed, I always charge the powered off phone until green LED showing. Then, I discharge the phone and go to sleep; leave it still powered off.
When waking up in the morning, I turn the phone on and find that battery level is around 65-72%, instead of 100%.
I then tested my phone by powering off and charging it again. I waited until grenn LED showing to turn it on. I found it showing 100% battery level.
According the test, I've assumed that the software update probable causes the phone consuming energy, even if it is powered off. This issue didn't happen when I used previous software version and potentially results battery cycle reducing due to battery consumption at nights.
I'd like to escalate this issue and hope HTC will respond for my escalation.
