Why does Apple 7 use battery so fast? In-depth analysis of battery loss and optimization solutions

Recently, Apple iPhone 7 users have generally reported that battery life has plummeted, which has become a hot topic. This article combines the discussion data of the entire network in the past 10 days to analyze the causes from multiple dimensions such as hardware aging, system updates, and usage habits, and provides practical solutions.

1. Statistics of hot discussions on the entire network (last 10 days)

3. Comparison of measured power consumption scenarios

According to the test data of technology blogger @digital小A (room temperature 25℃ environment):

Usage scenariosNew phone battery life2 years old machine battery life
video playback13 hours8 hours
4G call10 hours6 hours
Standby state48 hours28 hours

4. Five major power-saving optimization solutions

1.Battery health check: Settings → Battery → Battery health, if it is below 80%, it is recommended to replace it.

2.Turn off non-essential features:

  • Background app refresh (Settings → General)
  • Live wallpapers with parallax effects
  • Email push changed to manual acquisition

3.System downgrade plan: You can roll back to the iOS14 stable version through iTunes (data backup required)

4.Adjust charging habits: Avoid charging and playing at the same time, use the original 5W charger to reduce heat generation

5.Third-party battery options: Price comparison of well-known brand battery cells

5. Expert advice

Wang Lei, an Apple authorized engineer, said: "The battery design life of the iPhone 7 series is 2 years. It is recommended to turn on the optimized battery charging function. If there is a 20% power loss or abnormal heat generation in half an hour, you need to immediately check whether there is a leakage problem on the motherboard."

At present, Apple's official website still provides discounted battery replacement services (as of December 2023). It is recommended that users make an appointment for testing through the "Apple Support" APP. At the same time, consumers are reminded not to use fast charging equipment that is too hot, as this will accelerate the chemical decomposition of lithium batteries.

Through the above data analysis and solutions, we hope to help iPhone 7 users effectively extend the battery life of their devices. If the problem is still not resolved, the motherboard power management chip may be faulty and requires professional repair.
