Programmer or tester: two different jobs
Shops often buy one box expecting it to do everything. There are two tool families and they overlap only partly. A programmer reads and writes data on a part: True Tone profile, battery serial and cycles, vibrator or light sensor calibration. A display tester powers a screen outside the phone and shows an image on it, so you can check a panel for dead pixels, touch dead zones, lines and backlight before you fit it or before you accept a return. Some units do both, which is where the confusion starts.
QianLi iCopy Plus
The iCopy Plus (current revision 2.2) is a compact programmer with a built-in screen and three plug-in boards: display and touch, vibrator, and battery. It covers True Tone and light sensor data on iPhone 8 through the 14 series, vibrator serial transfer, and battery data reading and modification including cycle count reset. The battery board also works as a quick battery checker, showing voltage and reported capacity. It runs from an internal cell, which is handy at a counter but means you keep it charged.
It does not have a NAND socket, dot projector support or a display image test. For a shop that replaces screens and batteries and wants a cheaper option than the JCID V1SE, it is the usual choice. Compare with our JCID guide.
QianLi Apollo Interstellar One
The Apollo is a larger unit with a 3.5-inch screen and a 6-in-1 spec: True Tone restore, battery data read and write, vibrator serial, logic EEPROM for baseband, cable and headset verification test, and light sensor. Its True Tone coverage stops at the 11 series in the base version; the battery board covers 5s through 12 Pro Max, and newer add-on boards extend some functions. It is a good bench unit for older stock but check the model list against what your customers bring in before buying; in many markets the 13 to 16 series is now the bulk of the work.
DL S800 display tester
The DL S800 is the standard „test box“ in parts warehouses and busy shops. It is a 2.8-inch touch unit with a large library of flex cables; each cable matches one screen connector. Plug the screen in, pick the model, and the box drives the panel through colour fills, grey scales and a touch grid. It reports current draw as well, which tells you whether an OLED panel is healthy before it ever meets a phone. Current units support iPhone 6 through the 14 series and most Samsung, Huawei, Xiaomi, OPPO and vivo panels, with hundreds of cables available. The S800 also does True Tone write on iPhone panels, so it can replace a programmer for that one function.

Mega-Idea test boards and bench tools
Mega-Idea is QianLi’s sister brand for bench equipment. For a parts-level shop the relevant items are the iBoard logic board test fixtures, which let you power a bare iPhone board and attach a screen, camera and port to find which part is at fault without reassembling the phone; the battery activation and detection board, which wakes a deeply discharged cell and shows voltage and current for most iPhone, iPad and Android flex types; and the Super IR Cam thermal camera for finding shorts. Mega-Idea also makes the infrared laser desoldering station, which belongs in our back glass guide rather than here.
What a small shop should buy first
- Month one: one programmer. JCID V1SE if you want current model coverage, iCopy Plus if budget matters more. Both handle True Tone and battery, which is 90 percent of programmer use.
- When you stock more than 20 screens: a DL S800 with cables for your top ten models. Testing every incoming panel pays for the box after the first batch with a bad unit, and you can show a customer their old panel failing on the tester.
- When you start board repair: an iBoard fixture for the models you see most and the battery detection board for no-power diagnostics.
All of these are listed under Programmers and Testers; cables and fixtures are under Tools and Equipment.
Testing routine with a display tester
- Match the cable to the connector exactly. A forced cable bends pins on both ends.
- Run white, black, red, green and blue fills; look for dead pixels, mura and lines.
- Run the touch grid with a finger and a stylus; a cold OLED can miss touches at the edges, so let the panel warm for a minute.
- Note the current reading. A Soft OLED that pulls much more than a known-good sample is a return candidate.
- Write True Tone if the box supports it, then test again with the phone.
Safety note
Testers drive the panel with the phone’s display voltages, and a shorted panel can overheat the cable. Unplug a panel that shows nothing within a few seconds rather than leaving it powered. Keep the cable library in a dry box; corroded cable contacts produce false touch failures and you will reject good screens.
FAQ
Can a display tester replace a programmer?
Only for True Tone on iPhone panels, and only on units that list it. Battery data, vibrator and light sensor still need a programmer.
Does the iCopy Plus work with iPhone 15?
Check the current model list from QianLi; the 2.2 revision covers True Tone through the 14 series, and battery coverage depends on the board revision.
Which tester cables do I need?
One cable per connector family. iPhone X, XS and 11 Pro share one; 12 and 12 Pro share one; 13 and 13 Pro share one. Buy the set for the models in your top ten.
Is the Apollo still worth buying?
For a shop with mostly iPhone 8 to 12 stock, yes. For newer models the JCID V1SE or iCopy Plus 2.2 covers more.
