How Adaptive Charging Saves Android Battery

The Google

Bad battery life can ruin your Android experience. But even a large battery may still need to be charged at night. Moreover, batteries degrade over time. Adaptive Charging is a feature meant to help with all of these issues.

Why does battery life get worse over time

You may have noticed that the battery life gets worse if you use the phone for a long time. This is due to the “health” of the battery. As batteries age, they lose some of their capacity and won’t last long when charged.

A brand new battery will have a battery health of around 100%. This means you get the full potential of your battery capacity. What affects the health of the battery is the continuous charging and discharging cycle. no escape.

Keeping the phone charged in the 20-80% charged range is best for the battery, but it’s not always realistic in practice. You will put your phone on the charger at night and wake up 100% charged. While you slept, the battery was on a 99-100% cycle for several hours.

A smartphone battery is usually designed to maintain up to 80% health for 500 completion charging cycles. This means from approximately 0% to 100%. In most cases, that’s a lot relative to how long you’ll be using the phone, but all of those charging cycles add up. This is where adaptive charging comes in.

What is adaptive charging?

Staying in the 20-80% range that’s ideal, but it’s hard to do when your phone is plugged in for several hours each night. Adaptive Charging aims to take care of that for you in a smart way.

Adaptive charging keeps the battery at 80% overnight. Then just before you wake up, it will allow the battery to finally charge to 100%. This means that you avoid continuous cycling between 99-100% throughout the night.

Adaptive charging is the name of the feature on Google Pixel phones. OnePlus devices have a similar feature called “Enhanced Charging”. Samsung Galaxy devices call it “adaptive battery” and it also has a feature that lets you cover the battery at 85% all the time. (The iPhone has a similar feature called “Enhanced Charging” as well.)

Adaptive charging modes typically use your alarms and usage habits to determine the best time to reach 100%. If you find that the battery is not fully charged when you need it, you may just need to give it a little more time to learn your routine.

All of these different features are aimed at minimizing the damage that charging cycles do to batteries and keeping the battery healthy for as long as possible.

When improvements go too far

The battery improvements look good in theory, but they can go a long way. Samsung in particular is guilty of taking extreme measures to extend battery life. These actions can negatively affect your Android experience.

Website “Don’t Kill My App!” Ranks Android manufacturers and how battery “improvements” affect functionality. Killing aggressive apps in the name of battery life can lead to missed notifications and poor app performance. If you are a Samsung user, you may want to turn these features off.

In general, most Android devices handle battery optimizations well. Battery life is one area where manufacturers are motivated to make your experience as good as possible. If your Samsung phone battery life is poor, you may not want to use another battery. But too much of a good thing can be bad sometimes.

Overall, Adaptive Charging is a useful recent addition to Android smartphones. You should keep it enabled if it doesn’t cause any problems. Your battery will thank you.
