Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no single 'quick' method for estimating the condition of a mobile electronic device battery that is suitable for all types of devices without requiring a dedicated app to collect battery performance data.
Innovation Solution
A method and system that involves receiving device data from a mobile electronic device, selecting and executing an appropriate battery condition determination method specific to the device's make, model, and operating system, using existing data stored on the device, such as historical battery performance data, to determine the battery condition without requiring new data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dedicated app is used to collect battery performance data, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the battery condition estimation function from the mobile device itself and relocates it to a remote server. The server receives existing battery data from the device and performs the estimation calculations remotely, eliminating the need for dedicated estimation apps on the device while maintaining accuracy through multiple candidate methods.
Solution Approach 2:
The server is designed to handle multiple types of battery data from different device makes, models, and operating systems using a universal framework. It stores and evaluates multiple candidate estimation methods, selecting the appropriate one based on the device characteristics, thereby providing a multi-functional solution that replaces device-specific apps.
2Adaptability or versatility
If multiple candidate methods are stored and evaluated, then adaptability is improved, but device complexity increases
Solution Approach 1:
The server acts as an intermediary between the mobile device and the battery estimation process. It maintains a database of multiple candidate methods and device profiles, matching devices with appropriate estimation methods based on their characteristics. This intermediary approach enables high adaptability without requiring complex logic to be distributed across numerous device apps.
3Loss of time
If existing battery data is used for estimation, then loss of time is reduced, but measurement precision may worsen
Solution Approach 1:
The system performs preliminary actions by continuously collecting and storing battery performance data in the device's existing logs and databases during normal operation. When estimation is needed, this pre-collected data is immediately available, eliminating data collection delays. The server then applies multiple candidate methods to this existing data to maintain precision.
Solution Approach 2:
The server changes the parameter of data processing by applying multiple different estimation methods to the same existing battery data set. It evaluates results from various methods and selects the most appropriate one, thereby maintaining or improving measurement precision without requiring additional data collection time.

AI summary
A method for use in determining a condition of a battery of a mobile electronic device, comprises receiving, at a server, mobile electronic device data from a mobile electronic device, receiving, at the server, information relating to each candidate method of a plurality of candidate methods, each candidate method being configured for determining a value of a corresponding battery condition, wherein the battery condition value corresponding to each candidate method is representative of the condition of the battery of the mobile electronic device. The method further comprises determining whether any of the candidate methods are capable of determining a corresponding battery condition value based at least in part on the mobile electronic device data and the information relating to each candidate method, and, in response to determining that one or more of the candidate methods is capable of determining one or more corresponding battery condition values, performing one or more of the capable methods to thereby determine the one or more corresponding battery condition values. The method may be suitable for use in determining a condition of a battery of a mobile electronic device and, in particular though not exclusively, for use in determining a condition of a battery of a mobile electronic device which comprises or runs an Android operating system.
