The Lightning connector was introduced on September 12, 2012, with the iPhone 5, as a replacement for the 30-pin dock connector. [3] The iPod Touch (5th generation), iPod Nano (7th generation), [4] iPad (4th generation) and iPad Mini (1st generation) followed in October and November 2012 as the first devices with Lightning.
The iPad Mini 2 (formerly marketed as the iPad mini with Retina display, [2] officially iPad mini 2 with Retina display [3]) is a tablet computer designed and marketed by Apple Inc. It has a nearly identical design to its predecessor, the first-generation iPad Mini , but features internal revisions such as the use of an A7 system-on-a-chip and ...
Measuring with no load will give 6.86 V DC for MagSafe and about 3 V DC for MagSafe 2; the full voltage is provided after a ~40 kilohm (kΩ) load is applied for one second. [18] The outer large pins are ground. The central pin is used for communication between the computer and the power adapter following the 1-Wire protocol. The computer makes ...
An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
The iPad Mini 3 was announced on October 16, 2014 and was released on October 22, 2014, alongside the iPad Air 2; it features the same external hardware as the Mini 2 and the addition of a Touch ID fingerprint sensor compatible with Apple Pay. [6]
In semiconductor devices, problems in the device package may cause failures due to contamination, mechanical stress of the device, or open or short circuits. Failures most commonly occur near the beginning and near the ending of the lifetime of the parts, resulting in the bathtub curve graph of failure rates .
Verified for iOS 9.3 and later. 1. Double press the Home button or swipe up and hold. 2. Swipe up on the image of the app. 3. Re-launch the app and attempt to reproduce the issue.
When overheating, the temperature of the part rises above the operating temperature. Overheating can take place: if heat is produced in more than expected amount (such as in cases of short-circuits, or applying more voltage than rated), or; if heat dissipation is poor, so that normally produced waste heat does not drain away properly.
