Smartphone battery capacity – what you need to know?

What is smartphone battery capacity and what does it affect?

The battery life of a smartphone is an important indicator that depends on several factors. One of them is the battery capacity of the phone, which allows you to roughly determine how long the mobile device will work without recharging. We tell you what the battery capacity of a phone is, what it happens to be, and what it affects.

What is the battery capacity of a phone?

Phone battery capacity is the amount of electricity that a fully charged battery can deliver to a stand-alone device before it is completely discharged. Simply put, this indicator can give a rough idea of ​​how long the phone will work on its own before it is completely discharged.

A new phone battery uses almost 100% capacity. A small portion of the battery remains intact even at 0% to maintain the phone’s memory. However, over time, the available capacity decreases, so this characteristic is only relevant for short-term use of the phone.

Battery capacity is measured in milliamp-hours (mAh or mAh), and the value itself is individual for each mobile device. You can find it out from the technical characteristics of the phone, in the instruction manual or using a special application, for example, CPU-Z, which must be downloaded to the phone. The standard battery capacity varies from 3000 to 5000 mAh, but can be either more or less. Using this indicator, you can calculate the approximate battery life of a mobile phone:

• A battery with a capacity of 2000-2500 mAh will definitely require charging once a day.
• A battery with a capacity of 3000-4000 mAh at low loads will last two days.
• A battery with a capacity of more than 5000 mAh can work without recharging for 3 days.

Important ! The data described above is approximate, since a huge number of factors affect battery life.

Does the battery capacity of a phone affect its battery life?

The battery capacity of a phone cannot fully describe and predict how long a mobile device can operate without recharging. Other factors also influence this indicator:

1. Phone usage mode. Running applications, the time of using a mobile device, the brightness of the screen – all these indicators will largely determine how quickly the mobile phone sits down.
2. Manufacturer. An equally important factor, since it is depending on the manufacturer that the discharge time of the phone varies. For example, in independent tests, the 2800 mAh Google Pixel 4 phone ran out of power in the same amount of time as the 4000 mAh Samsung Galaxy S20 phone.
3. Battery status. Over time, the available battery capacity decreases , which is something to keep in mind when buying, for example, a used phone.

The main factor influencing battery life is the phone manufacturer, and therefore, the individual “stuffing” of the device: hardware and the degree of optimization in general. To determine the battery life of a smartphone more accurately, you need to focus not on battery capacity, but on the reviews of other users and tests of the phone’s full discharge time. In addition, the mode of using the phone has a big impact – active (mobile games, social networks, etc.) or more passive (checking notifications, calls and weather).
