Location Services: Apps that constantly track your location use considerable battery power.
Ambient Temperature: Extreme temperatures, both hot and cold, can negatively affect battery performance.
How Battery Health Impacts Performance
As your iPhone 11 ages, its battery health will inevitably decline. This means the maximum capacity of the battery decreases, and it can no longer hold a charge as effectively as it did when it was new. Apple provides a Battery Health feature in iOS that allows you to monitor the maximum capacity of your battery. You can find this information in Settings > Battery > Battery Health.
A brand new iPhone 11 should display a maximum capacity of 100%. As the battery degrades, this percentage will decrease. When the battery health drops significantly (typically below 80%), you may notice a decrease in performance and battery life. Apple may also throttle performance to prevent unexpected shutdowns on devices with degraded batteries.
Estimating Battery Life at 20% on iPhone 11
Determining the exact amount of time you can get from 20% battery is challenging due to the variables mentioned above. However, we can provide some general estimates based on different usage scenarios.
Light Usage (Basic Tasks)
Light usage includes tasks like checking emails, sending text messages, browsing the web for short periods, and making occasional phone calls. With light usage, you might expect to get 1 to 2 hours of battery life from 20%. This assumes your battery health is still reasonably good (above 85%) and you’re not running any power-intensive apps in the background.
Moderate Usage (Mixed Tasks)
Moderate usage involves a mix of activities, such as streaming music, using social media apps for a moderate amount of time, playing casual games, and taking photos. In this scenario, you can likely expect 30 minutes to 1 hour of battery life from 20%.
Heavy Usage (Demanding Tasks)
Heavy usage includes activities like playing graphics-intensive games, recording videos, streaming movies, using GPS navigation, and engaging in extended video calls. With heavy usage, you might only get 15 to 30 minutes of battery life from 20%.
Impact of Battery Health on Estimated Time
The estimated battery life mentioned above assumes a battery health of around 85% or higher. If your battery health is lower, the estimated time will be reduced accordingly. For example, if your battery health is at 70%, you might only get half the battery life compared to a battery with 85% health.
Tips to Extend Battery Life When You’re Low

Does the battery health of my iPhone 11 affect how long the last 20% will last?
Yes, the battery health of your iPhone 11 plays a crucial role in determining how long the final 20% will last. As an iPhone battery ages, its maximum capacity decreases, meaning it can hold less charge than when it was new. Therefore, an iPhone with a degraded battery will experience a significantly shorter lifespan on the last 20% compared to one with good battery health.
To check your battery health, go to Settings > Battery > Battery Health. If the “Maximum Capacity” is significantly below 100%, the battery’s ability to hold a charge has diminished. In such cases, you may experience faster battery drain, even when performing basic tasks. Replacing the battery is the only way to restore it to its original capacity and extend its lifespan.
What are some common misconceptions about iPhone 11 battery life and the 20% mark?
One common misconception is that the remaining 20% of battery life will always provide a consistent amount of usage time, regardless of the context. In reality, the battery consumption rate is highly variable and depends heavily on the tasks being performed. While 20% might last for an hour of light browsing, it could be depleted in just a few minutes while playing a demanding game.
Another misconception is that completely draining the iPhone 11 battery to 0% before charging is beneficial for battery health. Modern lithium-ion batteries, like the one in the iPhone 11, actually perform best when kept between 20% and 80% charge. Regularly draining the battery to zero can shorten its overall lifespan and accelerate battery degradation.
Is it better to charge my iPhone 11 when it hits 20% or let it drain further?
It is generally better to charge your iPhone 11 when it reaches 20% rather than letting it drain further.
