1 percent of your phone battery last longer :
Have you ever noticed that that last 1% of your phone’s battery seems to last so much longer than you actually expect? Well, let’s look into that a bit deeper.
Software vs. Hardware Estimation
The battery percentage in your phone is software-based on how the hardware works-that being the battery itself. Naturally, estimation is not always perfect. When your phone grows old, the accuracy of this estimation declines along with the battery. That’s why the shutting down of older phones even when it is showing 15% of the battery is another very common complaint that accompanied older iPhones.
Non-linear Battery Discharge
Lithium-ion batteries do not drain linearly. Going from 10% to 9% may not take the same amount of time to go from 5% to 4%. Several variables influence how a battery discharges:
-Usage: Running intensive applications drains the battery more quickly.
-Battery Health: Older batteries discharge charge less predictably.
The Hidden Reserve
The reason the last 1% seems to last longer is that your phone keeps a small **reserve charge**. This reserve ensures the phone can stay active or perform essential functions, like tracking your phone even when it’s technically “dead.” When your battery shows 1%, it might be tapping into this reserve, giving you a bit more usage time.
Psychological Factor
Another reason is you pay more attention to the last 1%. You are paying much more attention to your phone’s performance-which stretches time.
Battery Calibration Tip
To get better accuracy from the battery percentage estimates:
Sometimes let your phone completely drain then charge it all the way up to 100%. This will allow the software to recalibrate an estimate of how much battery life you have left.
In a Nutshell: The final 1% is more durable due to a combination of software estimation, non-linear discharge of the battery, and a small reserve charge. It’s also somewhat psychological—when you hit 1%, you begin paying more attention to your battery!
