Bench Signal #002 — three things from the bench, every Tuesday.
① This week's tip
Battery draining faster than expected after a screen replacement on iPhone 12 to 14. Before blaming the battery, look at the display.
Aftermarket OLED panels — even the better ones — tend to draw more current than the original, especially at higher brightness levels. The customer gets their phone back, notices it doesn't last as long as before, and assumes the battery is the problem. It usually isn't.
Test with a USB power meter before and after the swap if you can. A genuine panel at 50% brightness and an aftermarket panel at the same setting can have a measurable current difference. Document it. It makes the conversation with the customer much easier.
② Prompt of the week
Use this to build a warranty policy for your repair shop in one go:
I run an Apple repair lab. Write a clear, professional warranty policy covering: what's included in the repair warranty, how long it lasts, what voids it, how a customer makes a warranty claim, and what's not covered (pre-existing damage, software issues, customer-caused damage). Keep it under 200 words. Tone: professional, plain language, no legal jargon.
Review and adapt to your actual terms before using. Saves you writing it from scratch and gives you something consistent to hand to customers.
③ Resource this week
MacTracker — mactracker.ca
Free app and website with complete specs for every Apple device ever made. Model, year, chip, RAM, storage, battery, original price — all in one place. Useful on the bench when you need to confirm specs quickly without searching. Available on Mac, iPhone and iPad.
That's it for this week.
If this was useful, forward it to a colleague who'd appreciate it.
