Although the battery is one of the important factors in smartphones, large capacity no longer seems to be a top priority when choosing to shop.
Before learning about the problem, we need to know that there are smartphones with large capacity batteries on the market. This allows smartphones with weak CPUs and low-resolution screens to last for days, even weeks of use.
For example, at MWC 2024, Energizer introduced a 28,000 mAh battery smartphone that they claim can run for 94 days, or more than 3 months of use. To achieve that, the phone is about the size of a spare battery that many people carry around to charge their phones. It is unclear how successful it will be, but before that, the company failed to raise capital for the 18,000 mAh battery smartphone model on Indiegogo, which had less than 20 backers and only achieved 1% of the set goal.
To be clear, more practical phones with streamlined designs are preferred by users, such as the Moto G Power. Honestly, this is an area where budget phones often perform better than the flagships. If the device has a slow CPU, moderate battery life, and isn't used too much, the battery can last a few days.
Of course, more powerful hardware also consumes more battery, but even at just under 5,000 mAh, battery life is still quite good. For example, iPhone 5 has a 1,440 mAh battery, then iPhone These increased numbers stem from the larger phone size with more power-consuming components, but the battery life all meets user needs well.
Same with the Android world. Nexus 5 has a 2,300 mAh battery, then increased to 4,575 mAh with Pixel 8. Galaxy Z Flip5 also has a 3,700 mAh battery. All provide enough usage time for daily needs. Furthermore, the fast-changing technology integrated on them allows for quick recharging, it even takes less than 30 minutes to fully charge from 0-100%. This is more than enough for users to not need to worry about larger capacity batteries, which take up a lot of space on the device, making the device bulkier and losing necessary portability.
Talking about fast charging technology, let's take some examples. For example, OnePlus 12 can replenish a large amount of battery in just 10 minutes of charging. That's just enough time for some simple tasks, or even a 0-100% refill right before the user finishes showering.
Even wireless charging is increasingly improving charging speeds. This is a technology that is popular in cars, allowing people who work far away to know that their phone battery will be charged a large part of its energy before arriving at work. This is similar to electric cars. People may worry about range, but it's the charging speed that makes the difference in the trip. For many people, the fact that a car can run about 600km on a single charge is not as important as the fact that the car only needs 30 minutes to fully charge the battery to travel a distance of 400km.
After all, our phones have reached the point where worrying about uptime is no longer a real fear for most people. Even backup batteries are improving day by day, helping to solve part of the burden of traveling. Not only do they get better, but they also have higher capacities, faster charging speeds, and even support wireless charging. Therefore, choosing to buy a smartphone with a huge battery of 6,000mAh or more no longer seems important, instead experiencing modern features on the product is being given more priority.
