## Performance Impact

The Whatfix Mobile SDK does not affect the application performance, as it uses low-level OS APIs to optimize its performance.

#### Battery Consumption

The Whatfix Mobile SDK works at a very low sample rate, so it does not affect your app’s battery consumption.

#### CPU/GPU

- The Whatfix Mobile SDK is designed and built to run with as minimal a footprint as possible.
- For iOS, in a benchmark made on iPhone 12 pro, the average CPU spike was around 15-20%.
- In a benchmark made on Oneplus 6T for Android, the average CPU spike was around 15-16%.

#### Network

The Whatfix Mobile SDK sends data to the backend to better trace the end-user journey and facilitate Segmentation. The SDK network consumption for an average session depends on the number of campaigns and goals in the implementation:

Note:

Incoming data includes all the assets (images, content) of all the Walkthroughs and projects.

| Whatfix Mobile Performance based on implementation size |
| --- |
|  | **Heavy** | **Light** |
|  | **Incoming** | **Outgoing** | **Incoming** | **Outgoing** |
| **iOS** | 5.78 MB | 90.10 KB | 2.32 KB | 30.16 KB |
| **Android** | 5.67 MB | 45.03 KB | 1.34 MB | 26.59 KB |

**Heavy implementation includes:**

- 12-15 Walkthroughs
- 8-10 Elements

**Light implementation includes:**

- 4-5 Walkthroughs
- 2-3 Elements

#### Whatfix SDK File Sizes

- The iOS Whatfix Mobile SDK is approximately 6-8 MB.
- The Android Whatfix Mobile SDK is approximately 529.3 KB.
