The mobile ecosystem is moving towards longer battery life, and in that context, Xiaomi is preparing a Redmi with... a 9.000 mAh battery and 100W charging, which could break the current 5.000 mAh standard. The proposal aims not only for longer battery life but also for high-speed charging without significantly altering the phone's form factor.
The information comes from the well-known Chinese leaker Digital Chat Station, who claims that Internal battery testing has now been successfully completedWe're talking about a pack of a single high-density cell with silicon-carbon chemistry, a combination that improves energy density compared to traditional graphite.
What does it mean for a Redmi to go up to 9.000 mAh?
In practical terms, going from 5.000 to 9.000 mAh implies several days of light use or a very busy day without looking at the charger, something unusual in conventional models. Until now, these figures were mainly seen in ruggedized phones and others mobile phones with giant batteries and tablets, with clear compromises in thickness and weight.
The key here is that Xiaomi would bet on a single high-density cellavoiding multi-cell configurations that add bulk. The goal is to maintain a chassis closer to that of a typical smartphone, without making it an unwieldy block.
If confirmed, we would be facing one of the largest capacities seen in a mainstream mobile phone, a move that could reorient the competition from cameras or screens towards real autonomy.
The leak also mentions that the manufacturer has in laboratory 10.000 mAh units. Although that figure sounds like a milestone, for now it would be internal validations without a commercial release schedule.
The technology: silicon-carbon and 100W charging
The leap in capacity is explained by the use of silicon-carbon in the anodeThis allows for packing more energy compared to graphite cells. This chemistry is gaining traction in China and is starting to be seen in 6.000 and 7.500 mAh models without excessively penalizing the thickness.
Along with capacity, the load of 100W per cable It would be a cornerstone of the project. The combination necessitates fine-tuning the thermal management and charging algorithms to control the temperature in fast and prolonged cycles, an area in which Xiaomi has been iterating for years.
There is some caution in the industry regarding the long-term behavior of these cells compared to graphite, especially in capacity retention and cycle life. Mass deployment plans will depend on how well the durability and safety tests confirm them.
That there is already evidence with 10.000 mAh This doesn't imply that we'll see that figure in the short term, but it does point to a clear trend of increasing density which could be consolidated in upcoming releases.
Models, launch and what might happen in Europe
Sources place this battery in the Redmi Turbo 5 series, scheduled for its presentation in China between December and JanuaryAs usual, a international launch under the POCO brand, a recurring move by the company for Europe.
If it reaches the European market, it wouldn't be surprising to see adjustments in capacity or configuration due to homologation and battery logistics issues. China is adopting these high-density cells more rapidly, while Europe is progressing more gradually. in this section.
In terms of performance, the most consistent rumors link the model to the MediaTek Dimension 8500 Ultra, a 4nm SoC designed to deliver solid power without skyrocketing consumption, in line with the philosophy of the Turbo range.
Key details remain to be revealed, such as design, weight and thermal managementas well as the pricing strategy for Europe if a global version is ultimately released. In any case, range is shaping up to be the project's main selling point.
If the plans materialize as the leaks suggest, we will see Xiaomi push the market towards phones with several days of actual useThese vehicles offer very fast charging and require no major chassis redesigns. The challenge will be balancing capacity, safety, and availability outside of China.
