Wallhack's M-001 mouse exposes its PCB and battery through an open bottom frame instead of a solid shell, using the circuit board itself as a structural element. The mouse features a spring-loaded, click-to-eject battery system similar to SD card or Switch cartridge mechanisms, but as a result lacks a USB-C port and works only as a 2.4G wireless device.
Using Apple CarPlay or Android Auto can drain phone batteries and cause overheating because the device simultaneously runs normal phone functions and powers a tablet-like dashboard display, including a constantly updating map. The guidance recommends using a wired connection when possible, while cautioning that constant charging can itself generate heat, and suggests setting charge limits in phone settings or keeping the device in a cool, shaded spot in the car.
AirTags use a standard CR2032 coin cell battery that typically lasts a year or more, though heavy use of features can shorten that to a few months. Users can check battery status via the Items tab in Find My, which shows an orange icon only when a replacement is needed. Replacing the battery involves twisting off the steel back cover and swapping in a new cell with the positive side up.
Tesla and Rivian confirm that even when locked, their EVs run periodic battery management checks and use the high-voltage battery to recharge smaller 12V systems that power locks and computers. Tesla says app requests, climate preconditioning and infotainment also draw power while parked, and cold weather can skew range estimates independent of actual energy use.
Fleet company Geotab tracked over 22,700 EVs and found average annual battery degradation of 2.3 percent, rising to 3 percent for cars that frequently fast-charge above 100 kW versus 1.5 percent for those that rarely do. Hot climates added about 0.4 percentage points of extra yearly loss, while separate research from Recurrent on 30,000 US EVs found range drops to roughly 78 percent in freezing temperatures and 70 percent at -7°C.
A new guide explains several ways to check whether a CR2032 coin-cell battery still works, including dedicated coin-cell testers, basic multimeters, and a simple LED test where touching the LED's legs to the battery's terminals shows whether it can supply current. It also notes that AirTag and SmartTag2 users can check battery status directly through their companion apps before opening the device.
Reports note that closing background apps on an iPhone does not meaningfully extend battery life, contrary to common belief. Instead, settings such as disabling Background App Refresh and restricting apps' location access to only when in use are presented as more effective ways to conserve power.
Apple has released detailed DIY repair manuals and safety guides for the newly launched iPhone Duo, covering component replacement procedures, battery and glass safety precautions, and internal diagrams. Genuine replacement parts for the device are not yet available through Apple's Self Service Repair Store, though the manuals are live now.
Amazon is selling the LTE version of Google's Pixel Watch 5 for $399.99, a $100 reduction from its standard price. The cellular model allows calls, texts, and streaming without a paired phone nearby, and Google rates the watch's battery life at up to 30 hours.
WIRED's review of the Samsung Galaxy Z Flip8 highlights a 4,300-mAh silicon-carbon battery suited mainly for casual use, with charging capped at 25 watts wired and 15 watts wireless, and no magnetic Qi2 support. The phone's main 50-megapixel camera performs well in most conditions, while the 12-megapixel ultrawide lens is weaker and there's no telephoto lens, though cropping enables usable 2X zoom. New AI features include Horizon Lock for steady video, My FanCam for reframing group videos around a chosen subject, and Now Brief/Now Nudge for calendar and reminder assistance.
CNET reviewer Joseph Maldonado spent hundreds of miles riding Onyx's RCR 80V electric motorbike around New York City, focusing on daily livability rather than just performance. The bike starts at $4,699 for the Street version and $4,899 for Dual Sport, with a removable 80V/3.6kWh battery, claimed top speeds of 65-75 mph, and features like CarPlay, cruise control and regenerative braking.
General Motors says it used simulation technology to virtually test hundreds of thousands of battery configurations, completing the equivalent of 34,000 years of testing in under a month. The company now plans to apply the same simulation approach across other stages of vehicle development, having already spent roughly a decade researching lithium manganese-rich batteries that have yet to reach production vehicles.
