Has anyone installed a DEJI battery on an iPhone 15?

I’ve had my DEJI for about six months now. At first, I specifically checked to see if the battery capacity was degrading too quickly, as I’ve previously encountered cheap batteries that would start degrading after just a couple of months.
So far, everything’s been stable; the battery life hasn’t changed much since installation, so I’m happy with the purchase.

I repair mobile devices, so I work with these parts regularly. DEJI batteries fit the iPhone 15 perfectly.
DEJI uses Class A+ Li-ion cells, which often provide better battery life than the stock battery. For the iPhone 15, this is a great way to add a couple of extra hours of battery life, as they have a higher capacity than the standard battery. There are no surprises in terms of electronics: the controller is well-designed, and iOS detects the battery’s health without any fuss. The voltage is stable, and there are no shutdowns outdoors in winter. There’s no memory effect, so you can charge it in any mode.
As an iPhone battery supplier without overpaying for the Apple logo, this is one of the safest options. The battery is resistant to frequent charging, and built-in protection prevents overheating and deep discharge. Perfect for daily use.

Thanks for breaking that down so clearly. I’ve swapped a few DEJI packs into 15s myself and the extra runtime is noticeable, especially on heavy days. Clients stop complaining about midday top-ups and the health reading stays clean in iOS. No winter cut-offs either, which used to drive me nuts with cheaper cells. Appreciate you sharing the real-shop experience. Makes recommending them feel a lot less like a gamble.
