1. Analysis of common causes of short circuit in mobile phones
According to the survey data released by the digital maintenance organization @ Machine Repair Man:
| Fault type | Proportion | Typical performance |
|---|---|---|
| liquid penetration | 43% | Water streaks appear on the screen/buttons malfunction |
| Charger abnormality | 28% | The body is hot/charging is intermittent |

2. Five steps for emergency treatment
1.Power off immediately: Press and hold the power button to force shutdown. If operation fails, remove the battery (removable model)
2.physical isolation: Put the mobile phone into a sealed bag and coexist with rice/silica gel desiccant for 24 hours (only in case of water intrusion)
3.Disable heat source: Do not use a hair dryer or hand warmer for baking. High temperatures will accelerate component corrosion.
4.Professional testing: Take your mobile phone to the official after-sales point for short circuit diagnosis. Common test items are as follows:
| Test items | normal value range | Risk of exceeding the standard |
|---|---|---|
| Motherboard current | 0.8-1.2A | Component breakdown |
| battery voltage | 3.7-4.2V | Burn risk |
| Interface impedance | >5MΩ | Short circuit hazard |
5.Data backup: Export important data through professional equipment to avoid data loss during maintenance
3. Maintenance cost reference
According to the industry average price in November 2023 announced by @digital maintenance alliance:
| Maintenance items | Official after-sales price | Third party repair price |

2. Avoid using mobile phones in high-humidity environments such as bathrooms
3. Check battery health monthly (iOS Settings-Battery/Android Available AccuBattery)
