Review: XYIRMCYF Battery note 10plus - Very good product.ordered it for my Note 10 plus, work perfectly and I would say easy value for money. At the same time I don't see any changes in the capacity of the battery and how long it takes to run dry
Review: Great product, may have caused strange charging behavior (read desc) - These things last forever, they seem to have issues charging and I don't know if that's just because of my controller but it takes very specific cables to charge my controller now (chromebook chargers, and other high power chargers). My girlfriend's controller does not have this issue so I do not know the cause, just wanted to note it.

Very good product.ordered it for my Note 10 plus, work perfectly and I would say easy value for money. At the same time I don't see any changes in the capacity of the battery and how long it takes to run dry

### ⭐⭐⭐⭐⭐ Great product, may have caused strange charging behavior (read desc)
*by J***P on December 30, 2025*

These things last forever, they seem to have issues charging and I don't know if that's just because of my controller but it takes very specific cables to charge my controller now (chromebook chargers, and other high power chargers). My girlfriend's controller does not have this issue so I do not know the cause, just wanted to note it.

### ⭐⭐⭐⭐⭐ Cheap price to bring your phone back to life
*by D***S on January 16, 2026*

Great product. For as little as $30 brought my iphone back to life. The replacement process is not extremely complicated, but you definitely need an youtube video for instructions and visualization otherwise it would be easy to mess it up. Battery fits perfectly and plastic film with a new screen glue lines up very well.
