How Do We Understand Endurance?

This article is dedicated to all "AiOter" who love the Internet and pursue experience.If there are little places in the text, you can give more opinions and share the logic in the design.

 

First, clarify a few definitions:

What is the battery life?

How to define out of power?

How to define full charge?

How to check the battery level?

What is the power consumption?

What constitutes the total power consumption? What are the factors that affect battery life?

What are our ways to optimize battery life?

How to evaluate the battery life experience?

How to better optimize battery life?

 

Let's look at how we design products with these few questions!

1. Endurance: During the use of the product, from when it can be used to when it cannot be used usually. Not only does the battery level reach 0%, but even if the device cannot be used at 10%, it is also dead.

 

2. How to define no power: The product's primary function cannot be realized. That is, it is defined as no power.

 

3. How to define full power: After the device is fully charged through the charger, the total power signal given by the system will display complete control wherever the user can reach, which is the absolute power.

 

4. How to see the power of the battery: mAH is the measurement unit of battery capacity, but it is not the naturally stored energy. The voltage multiplied by mAH is the actual battery capacity.

 

5. What is the power consumption? Power consumption is an indicator of all electrical equipment, which refers to the energy consumed per unit of time.

 

6. What is the overall power consumption? Is the power consumption of the device below the average value of use and non-use?

 

7. What are the factors that affect battery life? The battery's total energy and the electrical equipment's overall power consumption.

 

8. What ways to optimize battery life include increasing battery capacity and reducing overall power consumption?

 

9. What constitutes total power consumption:

(1) Standby power consumption: The power consumed by the system when it is not working.

(2) Working power consumption: the power consumed by the system during regular operation.

(3) Scenario total power consumption: In different scenarios and scenarios used by other users, combined with the weight of standby power consumption and working power consumption, the actual power consumption is calculated.

 

10. Further on, how can we reduce standby power consumption?

(1) By choosing chips with lower power consumption, higher manufacturing process, and more suitable functions.

(2) Through better scene design, all external devices that do not need to be used during standby are turned off.

(3) Choose batteries with lower leakage current and better quality

(4) Use low-power components as much as possible in hardware design.

(5) More reasonable mutual wake-up logic.

 

11. Further, how can we reduce operating power consumption?

(1) With the same performance, fine motors and external equipment have a better energy efficiency ratio.

(2) Drive peripherals by selecting low-power interfaces.

(3) Reduce the working CPU frequency as much as possible

(4) Reduce the communication frequency between external devices as much as possible. Use low-frequency communication. (under the condition of guaranteed experience)

(5) Use a more suitable wire to reduce the wire resistance.

 

12. How to evaluate the battery life experience:

(1) Length of battery life

(2) Length of charging time

(3) The convenience of the charging process

(4) The clarity of the indication status during charging

(5) Are there power consumables? Used batteries, etc.

(6) How versatile the battery is

(7) Difficulty in purchasing batteries

(8) Cost of battery purchase

(9) Accuracy of the battery indicator

(10) Whether it can remind charging in time

(11) Is the wire of the charging cable universal?

(12) Whether the overall quality of the battery can be used for a long time

 

13. How to better optimize battery life:

(1) The key is understanding the user's usage scenarios clearly and giving response expectations for different usage scenarios.

(2) The charging is as convenient as possible; if possible, I would like it to last forever.

(3) From the design, follow a rigorous low-power strategy.
