All of the energy-conservation techniques that were described here are in the process of becoming embedded in soon-to-be-released, feature-rich cellular phones. Using these techniques, it's possible to estimate the resulting battery-life extension between recharges. Of course, some techniques are already available in existing devices. Those techniques weren't included as part of the energy-savings estimates for this article. Instead, the analysis focuses on the savings that were gained by applying DVFS and voltage-island-support techniques as well as ABB for standby-power-dissipation enhancements. Note that this analysis assumes the use of a Lithium-Ion (Li-ion), 1100-mA/hr. battery pack. The cost impact of these techniques wasn't included in the analysis.

In addition, two user profiles were used. The first is a typical, low-profile user (me) who essentially uses a cellular phone to make voice calls. Per day, my phone doesn't get more than 2 hrs. of active use. It is only on for around 14 hrs. per day. The second, heavy-duty user (my daughter) logs 6 hrs. of active usage. Her usage consists of a lot of calls, data downloading, listening to MP3 files, some picture taking, and some video watching. The phone is always kept on.

My current phone needs to be recharged every three to four days. My daughter has to charge her phone every day (roughly every 12 hrs.). Now, assume that when we get our new cellular phones, they will incorporate all of the energy-management and saving techniques that were mentioned in this article. I would be able to go through an entire workweek without recharging. At around 5.8 days, that's a 60% improvement. My daughter would need to recharge roughly every 30 hrs.—a very impressive improvement of 130%.

Cell-phone users of all varieties are calling for longer battery life. Yet next-generation, feature-rich cellular phones are going to further increase the pressures on battery life. Luckily, new techniques and semiconductor IP platforms are now available to help designers address this challenge head on.
