Whenever we think about upgrading our current phone or switching to another brand, the first important factor that we focus on is the battery life of that mobile. Although a good camera and some other factors also play an important role but a mobile with a good battery life gives you freedom. You can stream large data of video files and play games without any worry of losing your battery life quickly or any interruption because of charging your mobile after frequent intervals. According to a study conducted by Kantar’s World Panel CompTech Q3 2019, Battery life has become more important than its camera.
Fast Charger in the New Phone Box
Nowadays, it is a common trend to keep a fast charger with you always. It is better to give your mobile a fast charge instead of losing power completely. Many popular brands have now started to pack fast chargers into their phone boxes, such as Huawei, Google, OnePlus, and now even Apple has started this practice. However, it is also very important to know how fast charging affects your mobile battery? Whether using a fast charger a good practice or not? Does it degrade your mobile’s battery life over time?
All electronic devices including mobiles, use lithium-ion rechargeable batteries. As we haven’t seen any progress, when it comes to battery, in the last decade. However, manufacturers have enhanced battery life by introducing built-in power-saving features in the mobile and using software that don’t consume that much charge. Unfortunately, the researcher’s focus isn’t mobile, but cars and other appliances. Another reason for ignoring mobile batteries might be its size. Tesla 3’s rechargeable battery has a 4,000 times greater battery capacity than iPhone 11 Pro Max. It is also important to note that measurement units for cars and mobiles are different. For cars, the battery measurement unit is watt-hours whereas mobile batteries are measures in milliampere hours. Large battery size also gives you more power-saving tricks to extend your battery life.
Comparison of Fast Chargers of Different Mobiles
A conventional mobile phone charger gives you an output ranging from 5-10 watts. By using a fast charger, you can enhance its output by eight times. If we compare different fast chargers of popular brands, iPhone 11 Pros gives an 18-watts fast charger, the Galaxy Note 10 and Note 10 Plus give 25-watt charger. If you are a Samsung user, you can get an extra-speedy 45-watts fast charger. The important point to note here is using a fast charger doesn’t affect your battery’s life unless and until they have a flaw. The question that comes to everyone’s mind after knowing this is how it is possible to use fast charger without compromising on battery life. The answer is fast charging work in two phases.
In the first phase, your mobile charges from 50-70% in 10-30 minutes. In this phase, mobile absorbs a charge quickly without any major negative effects on battery life. Samsung claims its fast charger gives 70% charge in 30 minutes whereas Apple claims it gives a charge of 50% in 30 minutes. The last phase of charging is always very important. During the last 20% charge, due to voltage stress, your battery life can damage. Therefore, fast charger slows down during 2nd phase of charging. However, if your batter management system is well built, it can avoid losing your battery life early. Therefore, the last battery charging takes time. Due to the battery management system flaws, we have Samsung Galaxy Note 7 batteries exploding. It wasn’t a flaw of the software’s battery management system.
Overcharging Your Phone
Fast charging and overcharging are different. Overcharging means constantly plugging your mobile with its charger and giving it charge beyond its capacity. If you overcharge your mobile battery, it makes battery unstable, degrades its life, due to constant heat battery can explode and catch fire. However, better battery management systems shut off charging when it reaches 100%. It is also important to note here that even when your battery is 100% charged, it is under strain, that’s why makers of electric vehicle charge new batteries 80%. However, Apple always take the lead in battery life in its iOS 13 software which enables the battery to reach 100% without damaging its life. You can do so by changing your battery setting to Optimized Battery Charging. It will first let mobile charge to 80% and will charge slowly when the stress zone starts which is between 80-100%.
Discharging your battery to zero
It is not a good practice to let your mobile drain out to zero. In this case, due to chemical reactions, your mobile phone battery life can damage. However, modern mobile phones have several features that power off the phone before it reaches empty point to save your mobile’s battery life. It is good practice to charge your mobile when it reaches 30% of charging.
Heat, A True Enemy of Your Battery
High temperature degrades your mobile phones’ battery life, that’s why it is called true enemy of battery. It is a good practice to keep your phone away from heat. Overheating makes it less efficient and in some extreme cases, battery can explode. According to Isidor Buchmann, CEO and founder of battery technology company Cadex Electronics, temperature as high as 30C (86 degree Fahrenheit) can damage your battery life.
