BLU S91 Pro Battery life

BLU S91 Pro battery life can vary significantly, ranging from 11 hours and 33 minutes to 112 hours, depending on how the phone is used. The following usage profiles are relevant:

1.  Active Standby: ~112 hours

4 days and 16 hours? Really? This profile prioritizes a phone that's always reliable, perfect for emergencies or extended trips. Keep in mind, standby time will take a significant hit when you actually use the phone. Active standby time of the BLU S91 Pro depends on using it wisely and avoiding battery-draining background apps.

2.  Light Usage Profile: ~54 hours

If you primarily use your phone for communication but have all the apps you need and use them whenever you need them, you can expect the BLU S91 Pro to last for approximately 54 hours. That means 2 days and 6 hours.

3.  Moderate Usage Profile: ~42 hours

If you're a fan of YouTube and social media but don't have all day for it, this profile is for you. In this scenario, you can expect the phone to last for approximately 42 hours. That means 1 day and 18 hours.

4.  Heavy Usage Profile: ~27 hours

If you have high communication needs and staying informed is crucial for you, you will likely use your phone heavily. In this scenario, you can expect a battery life of approximately 27 hours. That means 1 day and 3 hours.

Within this category, there are three extreme subprofiles:

  • Continuous voice calls: ~24 hours.
  • Continuous video playback: ~15 hours and 45 minutes.
  • Continuous intense web activity: ~11 hours and 33 minutes.

It is important to note that these are just estimates, and actual battery life may vary depending on individual usage patterns and specific conditions.

Factors such as battery age, screen brightness, network signal strength, and background app activity can also impact battery life of BLU S91 Pro phone.
