CPU speedThe CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.

Whether you use your phone as a calculator, calendar, or as your daily lifeline to the world around you, chances are that you have your phone by your side or in your pocket at all times. That’s the beauty of mobile phones; they’re mobile. If you always have to plug into a power source to charge it, then you might as well call it a landline.

You’ll find that the average phone battery lasts around 10 hours with regular use, but there are phones with larger batteries, up to and over 5,000mAh, that can last a full day on a single charge. If you’re out and about or use your phone often for work, long battery life is an essential feature. Here are the factors influencing the battery life of today’s top phones.

Battery life

Battery life refers to the length of time you can use your smartphone before recharging it again. It’s essentially a measure of performance and longevity, meaning that the longer the battery life, the longer you’ll be able to use your phone without having to connect to a power source. Battery life varies from phone to phone and depends a lot on the phone’s battery power and usage and how often you charge it.

Battery power

Battery power is different from battery life and refers to the battery’s capacity to store a certain electrical energy amount. More battery power can indicate longer battery life, and the average phone’s battery power is usually around 3,000mAh. A battery with a higher capacity will store more energy and thus provide more electric power for your phone, so you can use it for a longer time without recharging it. As a general rule of thumb, if battery power is your biggest concern when comparing phones, look for phones with a battery of at least 5,000mAh

Fast charging

If you get a lot of use out of your phone throughout the day, then you’ll find that, regardless of the battery power, you’ll likely need to give it a little juice at some point. In this case, look for a phone that has fast charging capabilities. How fast are we talking here? Fast charging phones allow you to see a charge from o to 70%, for example, in as fast as 30 minutes.

How do you identify a fast charging cable? A USB 1.0 or 2.0 will charge at 5V and 0.5A for a total wattage of 2.5W.  If you’re using a USB 3.0 port, that charge can get pushed to 5V/0.9A for a total of 4.5W. USB 3.1 ports will allow you to charge at a maximum power output of 20V/5A for a total of 100W.

Wireless charging

Devices that offer wireless charging can be recharged by simply being placed on a compatible charging pad. Commercially available inductive charging became available to consumers in 2015 with the Samsung Galaxy S6 and the S6 edge release. While you still need to “connect” your phone to a power source (i.e., place it on a charging pad or charging dock), wireless charging does away with the need for cables.

If you need to charge your device on-the-go, it’s best to look into a portable power bank or charging case that allows you to carry the phone with you as it’s charging instead of placing it on a charging pad.
