Explore the Qnovo battery management software features
Qnovo's intelligent battery management software is a stack that consists of three distinct layers: First adaptive charging layer; second predictive health and safety layer; and lastly, battery analytics layer.
Adaptive Charging
The adaptive charging software layer offers the first line of battery management intelligence on the device. Its adaptive charging algorithms combine requisite diagnostics with learning chemical models to maximize battery life and longevity.
Qnovo's patented technology sends charge signals to analyze the battery's internal chemical processes. By studying the battery's chemical health and anticipating future aging, it dynamically adjusts the rate and degree of charging to meet some of the most challenging requirements such as those demanded by 5G smartphones.
The adaptive charging software simultaneously supports batteries of multiple types and energy densities made by wide range of manufacturers.
Predictive health and safety
The second layer performs supervisory and predictive functions based on its predictive battery health and safety algorithms. It uses anonymized diagnostic data collected and analyzed by the adaptive charging layer. It computes relevant metrics describing battery's chemical health and estimating its remaining cycle life.
Battery health from our battery management software reflects a true chemical state that can be trusted more than the traditional metric of capacity retention. A companion safety indicator provides an early warning of present battery faults that may lead to an explosion or fire.
Predictive battery analytics
The third layer is an analytics service in the cloud. It securely collects anonymized health and safety information from the predictive layer for each individual battery and aggregates the data across the large battery population in the field.
Our battery analytics cloud platform provides OEMs and network operators with an instantaneous view of batteries in the field, enabling them to identify and remove hazardous batteries from circulation before they pose a catastrophic risk. Current battery management systems have blind spots, and internal battery chemistry is invisible to them. Qnovo gives you the visibility that no one else provides today.

Qnovo battery monitor application
Explore the Qnovo battery monitor app features
The app displays four unique measures that no other application in the marketplace can provide.
Battery health
The state of health is a quantitative measure of the battery's internal chemical health and its internal materials' integrity on a scale from 100 (excellent health) to 0 (poor health).
Battery charge cycle
The cumulative number of charge-discharge cycles, also known as cycle count, defines the battery's age. The battery is designed to last 800 cycles under normal operating conditions.
Maximum charge capacity
The maximum charge capacity is the percentage of current maximum capacity relative to a new battery's maximum capacity. And this directly represents the battery's uptime. Your battery's performance is considered normal when the maximum charge capacity is between 80% and 100%.
Remaining life
An estimated number of months left before a battery's maximum charge capacity reaches 80%. When maximum capacity declines below 80%, the battery is at the end of its useful life.
This app cannot be downloaded separately and cannot operate independently of Qnovo's Adaptive Charging algorithms. The OEM or network operator controls the application's life cycle – testing, bundling, upgrade, and end of life.
The app operates in the background with a very small computational and memory footprint. The application operates and stores encrypted battery data on your smartphone to maintain your privacy. A small amount of battery data is securely transmitted to the cloud. The data are anonymized and do not contain any personal information about you. Only the network operator and its partners can review the cloud data to obtain a global view of the batteries' health on their network.
This app is running on the NTT Docomo network with supported 5G smartphones in Japan. LEARN MORE
