Replacement Battery for iPhone, Li-ion Polymer High Capacity Battery (11 Pro Max)

The only drawback is that installation is not beginner-friendly, but the kit makes it possible with the right preparation.Pros:Larger 5000mAh capacity extends phone life between chargesIncludes repair tools and manualBuilt-in safety features for reliable useFits the listed iPhone 11 Pro Max models accuratelyCons:Installation can be tricky for first-timersRequires several full charge cycles before reaching best performanceOverall, this is a solid replacement option for anyone looking to revive their iPhone 11 Pro Max with more battery life.

I bought this for my old iPhone 11 Pro Max that needed frequent charging. Installation took a little time, but the battery works well and gives longer usage. I like that it comes with built-in safety protections against overcharging and overheating. It also feels like good value for money compared to getting the battery replaced at a store. Hopefully, this helps me use my phone for a longer time.

Replaced the battery. It won’t charge past 1%. Will die while on the charger. Ended up having to get a new phone.
