One source at a supplier said there were delays in Apple's certification of panel producers, which were given strict power-saving requirements.
The objective of flow scheduling is to estimate the appropriate number of slots to assign to each connection and to subsequently schedule these connections according to their QoS requirements, power saving policy, DL/UL bandwidth ratio, and other related factors.
Similar conclusions can be made that the proposed policies outperform other control policies in power saving even with loose delay QoS requirements.
Figure 1 demonstrates that, for efficient bandwidth use, the BS must consider several factors, including the power saving policy, quality of services (QoS) requirements, channel quality variation, DL/UL bandwidth ratio, and burst structure.
As the QoS requirement getting strict, the joint power and time policy considering QoS requirement shows its advantage in power saving.
There is a tradeoff between power saving and performance, such as timing constraint and code size requirement, of nested loops.
Xen provides four governors related to power saving which are: On demand-choose the best P-state according to current resource requirements.
This section compares the power saving when using a wake-up receiver and the power saving when using the classical 802.11 power save mode (PSM).

Power saving and low delay are the important factors.
