Today, mobile phone charging speeds are entering an era of “ultra-fast”. At the moment, 120W fast charging is already a normal feature of many flagship smartphones. Some devices are already using 150W ultra-fast charging. In addition, Oppo’s upcoming 240W supercharger not only brings cell phone battery life and convenience to people’s use, but also significantly increases cell phone battery loss. Most brands in the smartphone industry now prefer lithium batteries. Unfortunately, lithium-ion polymer batteries in mobile phones have a certain useful life. The battery is also the most wearable part of a mobile phone.
Half the life of a lithium battery is calculated based on the number of charge and discharge cycles. The power of the smartphone goes from 0 to 100%, then 0, which is the complete cycle. If you charge your phone every half full, it’s half a cycle. This means that if you don’t wait for the battery to reach zero before charging, it’s half a cycle. This is because there is always a change from chemical energy to electrical energy, and from electrical energy to chemical energy. According to the industry standard for lithium batteries, the cycle life of lithium batteries in smartphones should be at least 500 times longer. The top battery can be used 700 times. This means that your smartphone’s battery will work effectively for about 1200 days. This is about 3 years.
Battery life cycle
The number of cycles in a lithium battery has been exhausted, but that does not mean that the battery is quickly discarded and unusable. Generally, after hundreds of charge and discharge cycles, battery life is significantly reduced. At this time, the flash charging technology is also significantly reduced. At this point, the battery life of the mobile phone is only about 60% of the original. In other words, if your smartphone has a lifespan of 100 hours on a single charge, you can only use it for 60 hours on a single charge.
As the frequency of charging and discharging increases, battery life will be significantly shortened. Therefore, the lithium battery of the mobile phone needs to be replaced in up to 3 years. However, if the battery life is relatively long or if the smartphone is for heavy users, the time may be shorter.
As long as a chemical reaction takes place, aging will appear slowly. Therefore, at 120W, 150W, and 240W charging speeds, the charging capacity is large, but if it can be charged once a day, it is the best in the current mobile phone battery technology.
The truth is that our charging habits are a major concern, whether or not we use ultra-fast charging technology. It can be a 25W charger or a 240W charger. The main focus is how often you connect your smartphone. If you maintain good charging habits on a regular basis, you will rarely need to replace your battery. In this case, the reason for replacing the battery is due to some external force.
There are many common charging habits and you may be practicing them. However, these habits are not always positive, and in fact many of them are negative. Below are some of the common bad charging habits that can quickly compromise battery life.
1. Long-term charging: The ratio of current to voltage under high power will increase naturally. This causes a rapid temperature rise, which is also an important reason why mobile phones are prone to catch fire. This is one of the main reasons why you shouldn’t charge your smartphone for a long time.
2. Use of available chargers: Free use of any charger is also a very common bad habit. Different brands of mobile phones, and even different series of mobile phones of the same brand, may use different charging protocols. Indiscriminate use of improper chargers not only fails to charge the battery, but also causes the phone temperature to rise sharply.This will eventually damage the battery
3. Keep your phone charged overnight: This is a common bad charging habit. Many brands now add the ability to reduce the charge when the phone is full, but you should avoid this habit to protect your battery.
