Smartphones and rugged handheld devices · Display size and resolution, processor, memory and storage, cameras, battery and charging, cellular bands and wireless, water and dust rating, size and weight, operating system
A smartphone combines a mobile phone with a computer, cameras and wireless connectivity in one handheld device; for business buyers the same choices apply to rugged and industrial Android handhelds used for inspection, logistics and field work. Settle three things before ordering: the display, processor, memory and storage the applications need, the cameras, battery, cellular bands and wireless for where it will be used, and the ruggedness, size, weight, operating system and support life.
Consumer smartphones and OEM/ODM phones, and rugged or industrial Android handheld devices with phone or data functions. Phone components (screens, cover glass, camera modules), two-way radios, tablets, POS terminals sold as systems and phone accessories are outside this page except where compared; camera modules, LCD modules and two-way radios have their own pages.

Apple's iPhone 16 specification lists a 6.1-inch (diagonal) OLED display at 2,556 × 1,179 pixels and 460 ppi with a 2,000,000:1 contrast ratio, an A18 chip with a 6-core CPU (2 performance and 4 efficiency cores), 5-core GPU and 16-core Neural Engine, storage from 128 GB, and a body of 71.6 × 147.6 × 7.80 mm weighing 170 g. [1]
Boardcon's RK3399 handheld device lists a Rockchip RK3399 processor (dual-core Cortex-A72 at 1.8 GHz plus quad-core Cortex-A53 at 1.4 GHz), 4 GB RAM, 32 GB storage, USB Type-C, HDMI, USB OTG, audio, MIPI camera and LCD, UART and microSD interfaces and Android 7.1, for industrial control and on-site inspection. [2] ARBOR lists rugged handheld devices, intrinsically safe devices and rugged Android and Windows tablets. [3]
Editorial calculation: pixel density = √(2,556² + 1,179²) ÷ 6.1 ≈ 2,815 ÷ 6.1 ≈ 461 ppi, matching the 460 ppi listed. [1]
Give the supplier the use case, display size and resolution, processor class, RAM and storage, operating system version and update support, cameras and scanning needs, battery capacity and charging, cellular bands and carriers, Wi-Fi, Bluetooth, NFC and GNSS, rugged ratings (IP, drop, intrinsic safety), size and weight, accessories, certifications and quantity.
02
The iPhone 16 lists a dual-camera system with a 48 MP main camera (26 mm, ƒ/1.6, sensor-shift stabilisation) and 2× telephoto option; up to 22 hours of video playback (18 hours streamed) and 80 hours of audio; fast charging to 50% in 30 minutes with a 20 W or higher adapter; FDD and TDD 5G NR bands plus mmWave on its US model; and an IP68 rating to a maximum depth of 6 m for up to 30 minutes under IEC 60529. [1]
Editorial note: cellular bands vary by model and region, so confirm the bands against the carriers and countries where the devices will be used. [1]
Editorial note: for field use, compare the IP rating, drop resistance and operating temperature on the rugged device's datasheet, and ask for intrinsically safe certification where hazardous areas apply. [3]

US FCC rules define a portable device as “a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that the RF source's radiating structure(s) is/are within 20 centimeters of the body of the user” (47 CFR 2.1093), which covers handheld phones. For such devices, 47 CFR 1.1310 sets specific absorption rate (SAR) limits from 100 kHz to 6 GHz. For general-population exposure the limits are 0.08 W/kg averaged over the whole body and a peak spatial-average SAR of 1.6 W/kg over any 1 gram of tissue, with 4 W/kg over any 10 grams for extremities such as hands, wrists and pinnae, averaged over up to 30 minutes. The occupational limits are 0.4 W/kg whole-body, 8 W/kg over 1 gram and 20 W/kg over 10 grams for extremities, averaged over up to 6 minutes. [4]
Consumer phones and rugged handhelds used by the public are judged against the general-population column; ask an OEM or ODM supplier for the measured head and body SAR for each band, alongside the radio and battery data above. [1] [2] [3]
Editorial calculation: the general-population 1-gram limit of 1.6 W/kg is one-fifth of the 8 W/kg occupational limit, and the whole-body limit (0.08 W/kg) is one-twentieth of the 1-gram peak limit.
| FCC SAR limit (47 CFR 1.1310) | General population | Occupational |
|---|---|---|
| Whole-body average | 0.08 W/kg | 0.4 W/kg |
| Peak spatial average | 1.6 W/kg over 1 g | 8 W/kg over 1 g |
| Extremities (hands, wrists, feet, ankles, pinnae) | 4 W/kg over 10 g | 20 W/kg over 10 g |
| Averaging time | Up to 30 minutes | Up to 6 minutes |
| Frequency range | 100 kHz–6 GHz | 100 kHz–6 GHz |
For a US launch, ask for the FCC ID, the SAR test report with head, body-worn and hotspot values, and the separation distance used in the body-worn test.
