If you happen to be the age of 13 or older then most likely you’ve used or owned a smartphone. Other than TVs, smartphones are one of the most commonly used devices on the planet. With all this phone usage, many questions surrounding battery drainage and efficacy tend to come up. People are now using the most resource-heavy apps than ever before, so phone batteries have become an integral part of the entire smartphone equation.
The average charge time of a modern smartphone is about one hour and 20 minutes. Now there are many factors that will change that number, such as battery capacity, power adapter wattage, and battery chemistry. In this article, we will go over how long it takes to charge various different phones and how to increase battery run-time.
To get the charge time of a phone, all you have to do is divide the phone’s battery capacity by
the amperage of the charger. For example, if your phone’s battery capacity is 3,000 mah and you use a 5v 1.2 amp charger, then all you do is divide the 3,000 by 1. 2amp. To make it easier, take away the zeros and do the math like this: 3 ÷ 1.2 = 2.5 hours.
For a 3,000 Mah phone battery using a 5v 1.2 amp charger, it will take 2. 5 hours to
fully charge the phone. When it comes to quick charge technology, such as Qualcomm, the voltage is dramatically increased when charging from 0 – 80%. So instead of 5v, you will see 9v, 12v, or even 20v. This ultimately increases the overall wattage.
Remember the higher the wattage the faster the charger.
How Does Fast Charging Work
Fast charging is basically what it sounds like, the ability to charge a standard cell phone fast. The phone is allowed to receive higher voltage and amps from its chargers in the beginning stage of its charging process. This will greatly increase the phone’s ability to charge faster. There are three steps to fast charging:
- Constant Current: At this stage higher voltage and current is allowed to enter the device. The phone will charge up to 50% in 30 minutes.
- Saturation: At this stage the voltage and current ( amps) have reached their peak and begin to drop.
- Trickle: At this stage the voltage and amps are at their slowiest and will slowly finish topping the phone off. This is why from 80% to 100% usually takes the same amount of time from 0 to 80%
Standards of Fast Charging
There are currently 5 standards of fast charging that different companies use.
- Qualcomm Quick Charge – Most Popular
- USB Power Delivery (USB PD) – Most Popular
- Samsung Adaptive Fast Charging
- Motorola TurboPower 15+
- Huawei SuperCharge 2.0
How long does it take to charge an Iphone?


A typical modern iPhone ( iPhone 11,12 & 13) battery capacity is anywhere from 3,000 – 4,400 Mah depending on which phone you buy. ( Please see the chart below.) That’s going to take around 2 – 3 1/2 hours to charge if you use a standard.
Apple iPhones are capable of fast charging. In fact, you can fast-charge any iPhone that’s version 8 or above up to 50% battery capacity in about 30 minutes. That’s pretty quick when you need juice fast.
Now, you will have to use a USB to lighting cable and the following adapters 18W, 204 29W, 30W, 61W, 87W, and 96W USB-C adapters.
please note: Even though you are utilizing higher wattage adapters, Your iPhone will not allow anything above 25 watts.

Top 5 ways to conserve a Phone’s battery life
- Lower Brightness- One of the quickest and most obvious feature to conserve battery life is the phone’s brightness. Lowering the brightness on your phone can increase the battery life
- Reduce Apps in the background- Limit your app usage in the background. Try to release the apps that are not currently being used.
- Use simple backgrounds-Instead of using an advanced interactive background, we suggest you use something simple that doesn’t utilize a lot of battery juice.
- Use low power mode- This is by far the best feature to use when trying to conserve battery life. Having low power mode on automatically disables some of the most power hungry apps and background tasks.
- Turn off Bluetooth and WIFI- Bluetooth and WIFI can drain your battery pretty quick. If you find yourself in a situation where you need to conserve battery life then turn off your bluetooth and WIFI temporarily
