Having a smartphone with a large battery capacity undoubtedly gives you longer usage time, which is undeniable. But does buying a durable battery smartphone result in longer user experience? In reality, battery capacity only reflects part of the device's usage time.
Battery capacity also depends on the battery-saving features integrated by the manufacturer, the processor, size, screen brightness, and usage frequency of each individual.
Let's explore a 'technology portrait' of smartphone battery life through the article below with 24h Technology! I believe you'll be surprised.
What does mAh capacity on a battery represent?
In theory, mAh stands for milliampere-hour, which is a unit of electrical charge equivalent to providing a milliampere of current continuously for one hour. This means that a 5,000 mAh battery can supply a 1mA current for 5000 hours.
But in reality, smartphones cannot sustain for hundreds or thousands of hours because they draw more than 1mA of current from the battery. The larger the current your phone draws, the shorter the battery life.
Large battery capacity does not necessarily mean longer usage time
The battery powers all the hardware and software inside your smartphone, from the processor to the screen and any other features equipped. It's obvious that different hardware and software will consume different amounts of battery.
Mid-range and low-end processors consume less power compared to flagship processors.Android Authority conducted a test to verify this. They used different smartphones with varying hardware specifications and battery capacities, ran the same internal benchmark test called Speed Test G, and then recorded the time each phone ran out of battery.
The results, ranked by increasing battery capacity. Speed Test G is a Stress test, pushing the hardware to its limits. Source: Android Authority. Looking at the chart, you can see that battery capacity is arranged in increasing order, but the test run time is completely unordered. The Pixel 3a XL is the champion here, with a battery capacity of only 3,700 mAh but providing the longest battery life.
Battery life also depends on many other factors
Various sensors on smartphones, stereo speakers, and QHD displays all affect battery life.
The S Pen on the Galaxy Note also consumes additional battery power.The trend of faster refresh rate displays is one of the reasons why smartphones consume more power. This is because higher refresh rates require more energy from the screen and processor.
Using 5G networks also significantly affects battery life. 5G modems and wireless components consume more energy than 4G.
Mid-range chips like the Exynos 980 and Snapdragon 765G with integrated 5G modems consume less power than chips with separate 5G modems like the Snapdragon 865.
So, what's the optimal battery life for a smartphone?
If you only need a smartphone for browsing Facebook, watching YouTube, reading news, listening to music, or playing a few games... then a battery capacity of 4,000 – 5,000 mAh is relatively sufficient. Some candidates meeting these needs include Vsmart Aris, OPPO A93, Vivo V21 5G,...
With a battery capacity over 5,000 mAh, it's suitable for gamers, high-resolution graphics editors, video editors, or for long outdoor trips. I believe devices like Xiaomi POCO X3 NFC or Samsung Galaxy M51 can meet these requirements. I'll leave the product links below for your reference!

Conclusion
Above are some insights into smartphone battery life that 24h Technology wants to share with you. Having a high battery capacity doesn't necessarily mean that a smartphone will have longer usage time, contrary to what most users think.
Therefore, when choosing a smartphone for yourself, you need to pay attention to other technical specifications as well as determine the purpose for which you will use it to have the best experiences.
