Remove “Important Battery Message” Without Extra Battery Tag-on FPC Cable

If you're facing battery pop-up issues on your iPhone 11–15 models but are hesitant to invest in expensive solutions like the JC V1SE, V1S Pro, or i2C iPhone repair programmer, PHONEFIX has a cost-effective option, W09 Pro Battery Life Pop-up Tester, to remove the "Important Battery Message" pop-up without extra Tag-on FPC cable. 

Cost-Effective Solution:

1. W09 Tester: The W09 Tester can be used in combination with i2C or JC tag-on battery repair flex cables to modify the battery information without the need for JC V1SE, V1S Pro iPhone repair programmer, or i2C programmers.

2. A More Affordable and Convenient Repair Solution: The W09 Pro tester can be paired with battery cables from any manufacturer, such as the popular HW-034 Pre-Programmed Battery Tag-on FPC Cable or OSS W12Pro battery flex cable, to remove "unable to verify this battery is genuine" after replacing the battery.

Important Information:

• The W09 tester is intended for professional iPhone repair technicians. It modifies battery health data and cycles after battery replacement but does not alter the actual battery life efficiency.
