Affordable smartphones in today's market boast significant improvements, with specs that keep getting better to meet basic user needs. So, what does a budget-friendly, high-capacity battery phone offer in 2021?
Samsung's latest release, the Galaxy A03s, promises optimal performance in this segment. Let's delve into why it might just be the ultimate choice.
What criteria must budget-friendly, high-capacity battery phones meet today?
Each individual has different usage habits, so the general standard for a durable smartphone is to meet your daily work needs.
Previously, budget smartphones typically came with battery capacities ranging from 3,000 to 4,000 mAh. However, users' demands are increasing, requiring even longer battery life.

In the past year, we've seen many smartphones with 5,000 mAh, even 6,000 mAh batteries, with 5,000 mAh being the predominant choice.
For basic needs like calls and basic social media usage, a 4,000 mAh battery can suffice for a day, lasting around 7-8 hours onscreen.
However, for heavy gamers, all-day online learners, or users of resource-intensive apps like cameras, a 5,000 - 6,000 mAh battery is a more sensible choice, often providing over 9 hours of onscreen time.
In terms of charging speed, at this price range, you'll typically find high-power chargers to replenish those hefty batteries, ranging from 10W to 18W.
Fast charging is also a significant advantage for high-capacity battery smartphones.If you can afford it, opt for products with fast charging technology to quickly replenish large capacity batteries. While some may habitually charge overnight, this feature may not be crucial for them. Hence, having fast charging is a definite plus.
Another significant factor is the energy efficiency of budget smartphones.

In this segment, most brands still utilize HD+ resolution displays, with no high refresh rates. Battery-saving software is commonly integrated by each manufacturer, so you need not worry too much about rapid battery drain.
At this point, I'd recommend selecting smartphones with newer-generation chips for stable performance and better battery efficiency. The Helio P35 and G35 from MediaTek, and Snapdragon 662 and 460 from Qualcomm, are the most reliable options in this price range.
Why choose the Galaxy A03s in this price range?

The Galaxy A03s is Samsung's recent entry into the budget segment. With its focus on affordability, long-lasting battery, and large display, I believe it's poised to lead the pack under $100, continuing the success of the Galaxy A02s series.
In terms of usage duration, the Galaxy A03s' 5,000 mAh battery can last over 9 continuous hours with a variety of tasks, from light browsing on Google and Facebook to playing Mobile Legends.
This means the Galaxy A03s can easily last a full day for users with mixed usage needs (tested at 100% brightness with all connections and notifications enabled).
For lighter usage like Facebook, Google, YouTube, and online learning, continuous usage for an hour can extend the screen-on time to up to 10 hours.

How much battery does gaming drain on this smartphone? According to our team's evaluation, playing games like Mobile Legends or League of Legends for an hour consumes approximately 11-13% of the battery. So, if you're gaming intensively, you might need to recharge by the end of the day.
The above statistics are based on continuous usage. However, if you're using the phone intermittently, mainly for calls and checking work-related messages, the Galaxy A03s can easily last until the second day.

In terms of charging, the Galaxy A03s comes with a 7.75W charger in the box, so the charging time is relatively long. However, it's not a problem if you're accustomed to overnight charging—just plug it in before bed and unplug in the morning.
