Future Apple iPhones may feature in-house battery tech that could improve battery life

Apple could be planning a major change for its future iPhones. The company might soon shift its smartphones to in-house developed battery, which could offer various improvements in battery performance compared to current iterations.

Apple iPhones may soon be powered by self-developed batteries

According to a South Korean report, the Cupertino based giant is working on developing proprietary battery tech. These cells could be employed on its future generation of iPhones. These handsets would likely be slated to launch in 2025. So the iPhone 16 lineup is unlikely to feature this technology. The report claims that the new Apple batteries for the iPhone will offer major improvements in battery performance.

This would likely be related to the overall battery life or the higher fast charging rate support. The ET News claims that the company is directly involved in the manufacturing of the materials that will be used in the new batteries. Apple will reportedly employ this in-house battery in the 2025 iPhones. Furthermore, the report adds that Apple is looking to improve the performance of cathode materials. The company is apparently also considering Carbon Nanotubes or CNTs as a conductive material for improved performance.

Apple might also plan to increase the silicon content in the cathode materials for its iPhone batteries. For those unaware, a battery houses a cathode and cathode materials. Newer smartphones feature graphite as secondary material, but the iPhone maker could be planning on increasing the silicon content in the cathode materials. This, in turn, could help reduce charging and discharging periods.

OPPO to mass-produce self-developed AP chip next year; mobile SoC to launch in 2024

OPPO has been working on its plan to reduce its reliance on other companies for semiconductors and in line with that, the company is reportedly all set to launch its own Application Processor (AP) next year.

If a new report coming from China is to be believed, then OPPO is working on a self-developed application processor (AP) which is expected to get launched in 2023. The mass production of the chip will be done using TSMC’s 6nm process.

Along with that, the company is also working on its own System On Chip (SoC) which will integrate the Application Processor (AP) and a Modem. This chip is expected to get launched in 2024 and will be manufactured using a 4nm process by TSMC.

OPPO has so far launched its own NPU chip named Mariana MariSilicon X. The company has said that front-end design, back-end design, IP design, memory architecture, ARM CPU design scheme, algorithm, and supply chain tape-out are completed by the company’s own team which includes the design, digital verification, and the back-end integration team.

The upcoming smartphone SoC from OPPO, which is expected to be launched in a couple of years, may not be on par with the offerings from Qualcomm and MediaTek in terms of performance. However, the company is expected to start using its own chips with budget or low-cost smartphones and then gradually keep using them to power more devices.

Vivo could launch its self-developed ISP chip “Yueying” next month with Vivo X70 series smartphones

Last month, we reported that Chinese smartphone brands Vivo and OPPO are working on their own in-house ISP chips. Now, more details about the upcoming chip have surfaced, along with information about the first smartphone packing it.

As per the latest report, Vivo’s first self-developed ISP chip, which is codenamed “Yueying,” could be made official next month, i.e., September 2021. It is also being reported that the upcoming Vivo X70 series could become the first devices to pack this new chip.

Vivo seems to be quite focused on developing its own chips as the company is planning to have a team of around 500-600 members in this department, claimed Hu Baishan, Executive Vice President at Vivo. In September 2019, while acknowledging the company’s plan of making its own chips, he added that Vivo started thinking about it in 2018.

The company is also looking to hire several new team members of the chip division for Research & Development and is willing to pay them handsomely, at least that’s what the report from ITHome indicates.

So far, we are aware of two chip-related trademarks from the company — Vivo SoC and Vivo Chip. The product categories covered by these two trademarks include central processing units, modems, computer chips, printed circuits, and computer storage.

Vivo has also planned to invest a huge amount in the Research & Development of 5G, Artificial Intelligence, and other emerging technologies. Its sister company OPPO is also developing its own chip which is expected to release with the Find X4 smartphone early next year. OPPO‘s chip development team has about 1,000 members.

Another Chinese brand, Xiaomi has already launched its first self-developed ISP chip named Surge C1 and is packed in the company’s first foldable smartphone — Mi MIX Fold which was launched last year.

The development of making their own chips seems like a precautionary move since Chinese companies are now investing more to become self-reliant after China-based tech giant Huawei was put on the “Entity List” by the United States. It effectively banned the company from doing business or procuring components from US-based companies.
