In today's fast-paced and tech driven world, Samsung Electronics stands out as a global leader, delivering smartphones known for performance, design, and unique features. With the increased power demands of Android apps, 5G connectivity, high resolution displays, advanced camera optics, battery capacity is becoming the central topic for both the users and the manufacturers. In response, Samsung started introducing high-capacity batteries in all the smartphones that it manufacture, be it a flagship or a mid-ranger.
That's not all as Samsung backs these high-capacity batteries with a software feature known as 'Battery Protection.' The battery protection feature is designed to limit the charging to a certain level to avoid wear. Always charging the phone to 100 percent affects battery's longevity and performance.
So, in this article we will see how incorrect charging patterns can affect your phone's battery and reduce its lifespan. We will also learn to enable battery protection in Samsung phones to avoid unnecessary stress on the battery. So, let's roll.
How Charging to 100 Percent Affects Battery Performance and Longevity
Charging your phone's battery to 100 percent can have negative consequences in the long run. Here's how the battery is affected when you charge it to full:
1. Stress and Heat
When the phone's battery is charged to 100 percent, the high voltage slowly reduces its efficiency. Additionally, high voltage increases the heat in the battery. While modern smartphones are sophisticated enough to manage heat generation, they are not fully reliable, as they depend on temperature sensors that may malfunction at any time.
2. Limited Charging Cycles
Lithium-ion batteries have a limited number of charge cycles. A charging cycle is completed with one full charge and discharge of a rechargeable battery. For example, if you charge your battery from 0 to 100 percent and then use it until it gets to 0 percent again, a cycle is completed.
However, it's important to note that you don't have to charge or discharge the battery from 0 to 100 percent to complete a cycle. If you use your phone's battery from 100 to 50 percent, then charge it back to 100 percent, and use it again until it reaches 50 percent, a full cycle has still been completed.
Smartphone batteries, like other Li-Po or lithium-ion batteries, have a limited number of these charging cycles (usually around 300 to 500 charge cycles). Therefore, charging the battery unnecessarily will impact its longevity.
Real-world Variability
Smartphone batteries are expected to last for 300 to 500 charge cycles. However, there are exceptions in some cases. For example, I used a Motorola Moto G series smartphone with a 3000mAh battery for 8 years, and the battery still works fine, although with reduced capacity.
I know it’s hard to believe that a lithium-ion smartphone battery could last more than 8 years and still powers the phone, but in those 8 years, my phone's battery could have easily completed more than 2,500 charge cycles—nearly four to five times the expected lifespan.
The reason for such an astounding lifespan is likely my usage pattern, as I used the phone with care and didn’t play heavy games. However, the phone was extensively used for watching videos, listening to music, and browsing the web. This demonstrates how reliable lithium-ion batteries can be when used with proper care.
So, charging your phone's battery to 100 percent most of the time won't harm it because the phone and the charger provide some protection measures using sophisticated circuits. However, it is advised to keep the charge level between 20% and 80%.
How to Enable Battery Protection in Samsung Android Phones?
Samsung Android phones come with a special feature known as Battery Protection, which helps limit the charging level to 80%. The 'Battery Protection' in Samsung Galaxy Android phones is a useful feature for protecting the battery. It prevents the battery from reaching 100% during charging. Here's how to enable it on your Samsung Galaxy Android smartphone.
- Go to Settings and tap 'Battery.'
- Now tap 'Battery protection.' If it is set to 'Off' then turn it 'On' by tapping the grey slider. It will turn blue once enabled.
- Now tap 'Maximum' to limit the charging to 80% level.
- You can also select 'Adaptive' or 'Basic' if you still wish to prevent overcharging without limiting the charging to 80% level. However, we suggest you to select the 'Maximum' option to conserve the battery. At times, you can select the 'Basic' mode if you ever wish to charge your phone to 100%.
FAQ: Frequently Asked Questions About Samsung Battery Protection Feature
Q. Why does Samsung only charge to 85%?
If your Samsung phone is charging to 85% only, it could be due to battery damage or degradation, or you may have the battery protection enabled on your phone. To disable it, explore this section.
Q. Is it worth using protect battery on Samsung?
Yes, it is worth using the battery protection feature on Samsung, as it saves the battery from unnecessary heat and stress. It also prevents battery degradation by limiting the battery charge to 80–85%.
Q. Is slow charging better for battery?
Yes, slow charging your phone is better than fast charging, as it produces less heat and stress. Fast charging should be used when you don't have enough time to charge the battery.
