The battery quality in mobiles

I have interviewed enough brand leaders to have something very clear: the battery is one of the characteristics that most influences the purchase of a smartphone. In Europe we seemed doomed to a very specific figure: about 5,000mAh that remained immutable generation after generation.

Chinese mobiles have begun to mark a trend with 6,000mahbreaking it in specific cases such as the Redmagic 10 Pro with its 7,000mah or the recent one Honor Power, with 8,000mah. In addition to the clear war in relation to the milliamps-Hora this eagerness for Chinese manufacturers to bring the best batteries goes further: the focus is in their quality and usability.

Crazy about capacity. Broken the 6,000th barrier, we published a piece that has not taken long to materialize: one regarding that this roof surpassed, We don’t know where the limit is.

Honor has already managed to introduce 8,000mah On a phone with an 8mm thickness, the same of any other traditional smartphone. Realme rises to 10,000mahabsolute madness. From one year to another, the 5,000mAh of the competition have become an obsolete figure, although everything that shines is not gold.

A change in industry. That this capacity has been unlocked has a main responsible: the Silicon-Carbon batteries. Here manufacturers have been pioneers by introducing this technology, which allows you to introduce much more energy capacity in the same size.

From a time to this part, this type of batteries has become more and more popular, although some manufacturers (including the Chinese) They reserve them for China for a simple reason: costs.

Beyond silicon. Longevity is another obsessions for this 2025, and OnePlus is the best example. His OnePlus 13t It is able to function without using battery, but electric current, when plugged in the current.

This function, which we already saw in the past in Redmagic mobiles (and Sony already flirted with it in some Xperia), is ideal to preserve the life of the battery on the scenario that suffers the most: when it is connected to the current making discharge cycles.

A perfect ally. A good part of the responsibility in these advances has it Catlone of the giants in the battery industry (mainly in the industrial and electric car spheres).

In recent years, Catl has collaborated with manufacturers such as Realme for the joint development of batteries, betting on silicon-carbon as material.

A dart to the rest of the manufacturers. The 6,000 (or more) MAH are becoming a standard, and now the glove will have to pick it up the rest of manufacturers outside China. Betting on this type of batteries is not cheap, but launching a terminal with a 5,000mAh battery will begin to become a competitive disadvantage for the rest.
