When asked what has captured the attention of consumers for the latest round of domestic mobile phones since the fourth quarter of last year, some might cite the upgraded CPU chips, undeniably a significant enhancement. Personally, however, I believe the most impactful upgrade lies not in the CPU but in the battery capacity, which directly influences the user experience. High-end flagship models might not see a dramatic difference as the latest chips, while more powerful, also consume more energy, offsetting any potential gains in battery life. In contrast, mid-range and sub-brand models from various manufacturers have seen remarkable improvements.

Battery capacities have generally seen an increase of 1000mAh, with 6000mAh now considered the minimum standard, and most new models boasting at least 6500mAh. A few even venture into the realm of 7000mAh. Coupled with chips that consume slightly less power, these enhancements make battery life more suitable for everyday users. One might think that with capacities reaching such heights, further upgrades within the year seem unlikely. Yet, surprises still await.

According to recent online leaks, some domestic mobile phone manufacturers have commenced testing batteries with capacities of 7800mAh or higher, marking a substantial leap from current mainstream capacities. Notably, these giant batteries are expected to be featured in mid-to-low-end models in 2025, with high-end and flagship models capped at around 7000mAh due to space constraints within the devices. High-end models, packed with advanced features, require more internal components, limiting the space available for larger batteries.

Mid-to-low-end models, often lacking in other functional aspects, have turned to increasing battery capacity as a practical strategy to attract users. Equipping a phone with nearly 8000mAh is indeed astonishing but highly practical for users. Many would likely support a reasonable increase in thickness for such a significant boost in battery life.

Take the realme Neo 7, for instance, which features a 7000mAh battery and measures 8.56mm in thickness. If future models adopt an almost 8000mAh battery, an overall thickness exceeding 9mm would be plausible. Smartphone design follows a cyclical pattern: initially thick due to technical limitations, then thinner to meet user preferences, and now thicker again as manufacturers focus on battery capacity amidst a lack of other innovations.

This substantial increase in battery capacity could significantly reduce the need for power banks. With a full charge in the morning, users can easily get through the day without worrying about running out of juice, making power banks obsolete. Moreover, such large batteries can even serve as power banks, offering reverse charging capabilities. For users, saving money on power banks is an added bonus.
