Key Takeaways
1. Battery Size Shift: Batteries with 7,000 mAh or higher are now being used in regular-sized smartphones, moving away from their traditional use in rugged devices.
2. Technological Advancements: Recent improvements in battery technology, driven by the electric vehicle industry, have led to lighter batteries with better energy density.
3. Xiaomi’s Launch: Xiaomi is releasing the Redmi 15 5G with a 7,000 mAh battery in Western markets, maintaining its standard design without modifications.
4. Battery Performance: The Redmi 15 5G offers impressive battery life, ranking highly for load runtime and being suitable for gaming and media consumption.
5. Value for Money: Despite its average specs and design, the Redmi 15 5G is a strong choice for those prioritizing long battery life within a budget-friendly price range.
Up to now, batteries with a capacity of 7,000 mAh or higher were typically found in rugged devices. These devices tend to be heavier and bulkier because of their protective features, making the extra weight from the battery less noticeable.
Advancements in Battery Technology
Recently, there has been significant progress in battery technology, largely due to the rise of electric vehicles. Modern batteries now provide much better energy density while being lighter in weight.
In China, manufacturers have already started putting batteries larger than the standard 5,000 mAh in “regular-sized” smartphones. Oddly enough, in Europe, only slimmer versions have been offered, and the reason for this remains unclear.
Xiaomi’s New Launch
However, it seems that the issues have been addressed, as Xiaomi is now introducing the Redmi 15 5G with a 7,000 mAh battery in Western markets, without any changes.
Our thorough evaluation of the Xiaomi Redmi 15 5G shows that it is a completely average, basic budget smartphone. This is clear from the plastic body, which isn’t particularly durable and has a quite simple design. You shouldn’t have high hopes for the speaker or processor capabilities either.
Impressive Battery Performance
Nonetheless, in terms of battery life, this model is tough to beat. It might “only” be in 38th place among all smartphones in the WLAN test, but it is bested only by much pricier smartphones and the tougher outdoor models.
For load runtime, the smartphone even secures the top spot with a runtime of over 7 hours. Those who enjoy gaming or binge-watching movies and series will find the Redmi 15 5G to be a solid choice.
The Xiaomi Redmi 15 5G has its drawbacks, but if you mainly want a smartphone with long battery life, it will be hard to find a better option at this price range.
