The Roomba 980 was released in September 2015 and contains a new iAdapt 2.0 visual simultaneous localization and mapping (vSLAM) navigation system, which allows it to clean an entire level of a home more efficiently. The 980 also features Wi-Fi connectivity and an iPhone and Android app. [51] [52] The Roomba 960 was released on August 4, 2016.

A simple charger typically does not alter its output based on charging time or the charge on the battery. This simplicity means that a simple charger is inexpensive, but there are tradeoffs. Typically, a carefully designed simple charger takes longer to charge a battery because it is set to use a lower (i.e., safer) charging rate.
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
[7] [8] The negative electrode material may have the same three parts, only with carbon replacing the lithium-metal-oxide. [7] [8] The main difference between lithium-ion polymer cells and lithium-ion cells is the physical phase of the electrolyte, such that LiPo cells use dry solid, gel-like electrolytes, whereas Li-ion cells use liquid ...
The controversy first emerged in late-2016, when it was reported that since a recent iOS update, some iPhone handsets had begun to experience unexpected shutdowns when their battery capacity reached 30%, caused by drops in the battery's terminal voltage below a threshold of around three volts required for operation of the device.
