Consumer electronics change fast. By 2025 five clear shifts will alter how people use everyday devices - homes will predict needs, phones will handle AI locally, foldable screens will sell at scale, wearables will read blood markers without needles and gadgets will work together through one identity.
  - Smart-home gear adds prediction. Clocks plus usage logs let lights, speakers and thermostats act before the owner speaks. Apple plans to update the HomePod besides Apple TV chips in 2025; the new silicon runs a larger Siri model on the box itself - the assistant can raise heat at 6 a.m. on workdays and dim lamps at 10 p.m. without external servers.
 
  - Phones keep the AI model inside. A 3-billion-parameter large language model fits in 4 GB of RAM but also answers questions in milliseconds - no data leaves the handset. Apple Intelligence, Samsung Gauss or Qualcomm's Hexagon NPU all run the same way - the keyboard drafts a reply, the photo app erases a passer-by and voice dictation works in airplane mode.
 
  - Foldable LCD next to OLED panels last 200 000 cycles as well as cost 30 % less than 2022 parts. Google, OnePlus besides Honor now sell book-style and clamshell models at USD 799 - 1 199. Analysts expect 45 million units in 2025, up from 16 million in 2023.
 
  - Watches, rings or adhesive patches add LED photodiodes, skin temperature pixels and 1-lead ECG traces. The Apple Watch Series 10 reports blood pressure trends - the Samsung Galaxy Ring measures nightly heart-variability - printed patches from Huami track lactate during exercise. Users view hourly graphs on the same phone app and share PDFs with clinics.
