This ultra-low-power consumption permits the use of a very small capacity battery of 100 mA-hr for lifetimes exceeding ten years; as a result a battery tag that is very close to a passive tag both in form factor and cost is made possible.
Depending on the position update rate, a small battery may suffice for several month of tag operation.
The IoT device can potentially last for more than 5 months (transmission interval of 30 seconds) on the coin cell battery (capacity of 120mAh) without any energy harvesting, sufficiently long for the dark seasons of the year.
Since people usually charge their smartphones daily, it is unnecessary to extend the battery life to last more than a day.
In fact, limited battery lifetime is one of the biggest obstacles facing the current utility and future growth of increasingly sophisticated "smart" mobile devices.
In fact, limited battery lifetime is one of the biggest obstacles facing the current utility and future growth of increasingly sophisticated “smart” mobile devices.
We show that it is possible to decrease the energy consumption per tag payload delivery with more than 10 times, resulting in a 50% increase in tag battery lifetime.
This algorithm allowed the smart battery to gauge the network's illicit attack density and adjust its polling rate to efficiently detect attacks, while conserving battery charge life.
The insufficiency of battery lifetime has become the biggest limited of mobile smart-terminal, offloading of mobile computing is a potential effective method to extend the battery lifetime of mobile smart-terminal by executing some computation of applications in remote servers.

Finally, the chemical compatibility in the battery must allow a long service life.
