[Updated title after further investigation]
Since the latest updates I recognize a degradation in performance and power consumption on my Pi2.
I use it mainly for htc, pvr and some headless stuff.
It got worse in early november, my remote was unresponsive or not responding at all (there was no lirc update), playing music (hdmi out) is pausing from time to time, live tv streaming from pi to anouter device is unusable since then, tv recording (no hd content) often produces corrupted streams. It seems to get worse with increasing uptime. Restarting services alone (kodi, tvheadend, lirc, ..) doesn't fix the issues.
Also (around the time since the new 'low power icon' has been introduced) the power consumption seems to have increased. I see the new yellow flash icon far more often than the old rainbow square. I use to have this only when my usb hd spun up, after the degration I see it when also when the disk is already spinning or when the disk is sleeping.
Some settings: Clocking settings are "medium" (arm_freq=900, core_freq=333, sdram_freq=450, over_voltage=2), I use "dtoverlay=lirc-rpi" and have set "max_usb_current=1" for my 2.5A amp. Attached is a 2.5" usb disc, and an usb dvb tv receiver.
