What is a mAh battery?

Your phone’s battery is the most important part of the hardware on the device, as nothing can ever happen without it. But, these lithium-ion technological wonders still remain puzzling to many smartphone users. For the global population, handsets and tablets may as well run on magic crystals for how great the inner workings of batteries are known.

What is mAh?

mAh indicates milliamp-hour and is a unit that measures power over time. It is commonly applied to measure the energy capacity of any battery. Overall, the more the mAh, the longer the battery capacity or battery life.

mAh is calculated by multiplying the duration the battery lasts by the amperes of the discharge current

Relationship to Battery Life

To calculate a battery’s life, you need to divide the capacity of the battery by the current required by the object that it powers.
While a more significant number indicates battery power, larger mAh batteries may not be better if it is a bad quality battery. It merely means it can store extra power.

Usage factors of a mAh battery

Cell phone battery life is mainly reliant on the method in which you use the phone. The more features you operate at the same time on your phone, the more current it requires, and the faster the battery’s capacity reduces. This is why using WiFi or even running complex games on your phone consumes the battery very quickly. As such, a battery with a larger capacity that is used to power a smartphone might persist for a lesser time than a low-capacity battery that powers a basic device.

Battery Size

Even though higher-capacity batteries usually last for a longer time than lower-capacity ones, they are not suitable for use in all devices. To obtain a higher capacity, battery makers have to fit more extra cells into each battery. Cells are the elements of a battery in which the chemical reaction needed to produce electricity happens. Raising a battery‘s cell count can turn out to increase both the size and weight of the battery. It makes it inappropriate for use in slimline devices like smaller cell phones and netbooks. The speed and temperature of electrical current discharge influences the overall capacity of the battery. Poorly made batteries usually heat up too fast, which results in performance issues or degraded capacity.

Advantages and disadvantages of a mAh battery

Advantages

  1. The working voltage of the single battery is higher than the voltage of Ni-MH and Ni-Cd batteries.
  2. The capacity density is large
  3. Self-discharge is small
  4. Its capacity loss is slight after being placed for a large amount of time.
  5. Good security performance.

Disadvantages

  1. The battery cost is huge, and the electrolyte system is hard to purify.
  2. Need to protect the line control
  3. Overcharge or discharge can cause the reversibility of the internal chemical substances of the battery to be damaged, thus affecting the life of the battery.

Which phones have the best mAh battery?

The Samsung Galaxy S10 sets in a 3,400 mAh while the Galaxy A50 is one step above with 4,000 mAh.
The most modern smartphones today come with a capacity of atleast 2,500 to 4,000 mAh.
Moto G7 Power claims the number one spot with approximately 15 hours and 30 minutes of battery life, while the iPhone 11 has just 11 hours and 16 minutes of life span.
Hence, Android phones tend to do much better than iPhones in the battery life department.
But of course, a higher mAh doesn’t certainly mean the phone is better. There are many different factors to look at when buying a new smartphone
