If you notice that your phone was charging very slowly overnight instead of being charged immediately to 100 percent, then you have already experienced adaptive charging technology. It is one of those features that the majority of people never really pay attention to. This functionality is quite useful and is something that will help you preserve your smartphone for longer. Here is the guide that will cover how adaptive charging functions.
What Is Adaptive Charging?
Adaptive charging is a clever battery management technique that utilizes real-time information regarding the daily usage patterns, temperature of the battery, charging cycles and connection time, allowing it to adjust the battery charging capabilities accordingly. Unlike the traditional method that maximizes the charging of the battery until it reaches the 100% mark, adaptive charging takes its time, generally postponing the last phase of charging until you need your device the most.
The goal of this system is to reduce the time the battery stays in the 100% state as staying in this state for an extended period of time contributes to the battery damage. By knowing your habits, the algorithm on the device determines the approximate time you will unplug the phone and adjust the charge level accordingly.
As for the names of the particular function it varies according to the particular brand:
- Apple stands for Optimized Battery Charging
- Google and Android are in favor of Adaptive Charging.
- Samsung refers to it as Adaptive Fast Charging or Battery Maintenance
How Adaptive Charging Works?
Adaptive charging utilizes some behavioral insights and battery information for its working. Here is how this works in a simple way:
- Tracking habits: The device monitors things like when you often plug your phone in at night and when you take it out in the morning (often following the setting of an alarm clock in the phone).
- Charging at a slower pace: Based on what it has learnt in the first bullet, the battery is charged to a certain level (normally, within 80-90 % of the maximum capacity) and then the pace is reduced.
- Timed completion: The battery gradually reaches 100 % about the time when it is going to be used instead of charging over the night.
- Continuous updating: If the user takes the phone sooner than usual, the device adapts to this new pattern in order to ensure that it is ready to use at the right time.
Additionally, some charging systems can take into account battery temperature and voltage parameters.
The Importance of Adaptive Charging
Lithium-ion batteries are commonly used in portable gadgets like smartphones, tablets, and laptops. However, batteries have a tendency to wear out because of the chemical reactions that take place inside them. Although battery degradation cannot be prevented, the battery charging method is an important factor affecting battery lifespan.
Adaptive charging is important for various reasons, such as:
- Reduces time spent at full charge: Shortening the battery stay at the fully charged state, and consequently prolonging its lifespan. A battery not being charged in adaptive mode will spend more time at 100% charge, thus deteriorating faster than the battery being charged in adaptive mode.
- Reduced heat generation: Charging requires energy that transforms into heat, thus creating a problem for the battery.
- Helps to prolong battery life: Such minor improvements contribute to enabling your battery to keep charge for longer time.
- Works behind the scene: adaptive charging gives you benefits of charging without having to do anything at all.
Is adaptive charging the same as fast charging?
In fast charging, energy is supplied more rapidly than regular charging. Nevertheless, adaptive charging has to do with the timing of charging, which suggests slowing down the final stage of the charging. Still, in many devices, both systems are used at the same time. For example, charging may be fast up to 80% and then shift to adaptive charging.
How to Check and Enable Adaptive Charging
In summary, although the majority of devices do have the adaptive charging function enabled, it is possible to verify this through the device’s settings.
- For Android devices: navigate to Settings > Battery > Adaptive Charging. It must be noted that in some cases, the brand’s name for this feature might differ.
- For iPhones: navigate Settings > Battery > Battery Health & Charging > Optimized Battery Charging.
- For Samsung devices: The way to enable this function is Settings > Battery and device care > Battery and additional battery settings.
It is important to mention that there are variations of this feature where users need to set an alarm since the system uses this alarm to determine when to stop charging the device.
Will This Feature Slow Down My Smartphone’s Charging Process?
Adaptive charging does not affect the actual speed of the charge — the device will get charged fast to a certain point, just like it always has. It just prolongs the end part of the charge cycle, which usually takes around 10–20% of the charging process. The operation of adaptive charging won’t be obvious if you disconnect your device from the mains before reaching 100% battery capacity.
When you find yourself in need of a fully charged device immediately (for instance, before an unexpected journey), most systems will allow you to bypass the adaptive charging features just by pressing one button.
Adaptive Charging vs. Manual Battery Care
Before the advent of adaptive charging technology, battery-wise consumers had to vigilantly manage their charging behaviour manually — unplugging once the battery showed an 80% charge, staying away from charging overnight and being aware of the excessive heating of the battery. Adaptive charging has made such wisdom automatic since it follows the same principles that battery specialists have recommended over the years while imposing no obligations on the user.
Still, however, it is advisable to stick to some useful practices: avoiding extreme temperatures, using accredited chargers and preventing complete battery drainage work in harmony with the capabilities offered by adaptive charging.
Final Thoughts
What is adaptive charging, really? This is the technology that makes use of a smart and automatic system that knows when you are using the charger to help you keep your device’s battery safe for a longer period. Since batteries are among the components that cost much more than the other parts of the devices, the use of adaptive charging has its great impact on battery life.
In case your device features adaptive charging, the best decision is to keep it operational at all times.
FAQs
In fact, the purpose of adaptive charging is to protect your battery’s life. By limiting the time your phone is fully charged, the technology helps to limit battery wear.
Indeed, it is possible. Generally speaking, adaptive charging is activated by default, but you can easily disable it through the battery settings of the device if you are OK with charging your device at normal speeds instead. It is true that many devices let you use standard charging for a specific occasion without turning it off completely.
While you are using adaptive charging technology, this is indeed a normal case. This feature was specifically developed to charge your phone in the most effective way.
