🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Restore the legendary battery life of your UMIDIGI Power 7 Max with this 10000mAh replacement battery. Released in 2020, the UMIDIGI Power 7 Max made headlines with its massive 10000mAh battery — one of the largest ever put in a mainstream smartphone — delivering up to a week of moderate use and days of continuous video playback. The Power 7 Max features a 6.8-inch display and is designed for users who prioritize endurance above all else. After years of daily charging cycles, the original battery capacity naturally degrades. This Li-ion Polymer battery restores the full 10000mAh capacity, bringing back the multi-day endurance that set the Power 7 Max apart from virtually every other smartphone. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Designed for Unmatched Battery Endurance: The UMIDIGI Power 7 Max was built for users who need a phone that lasts — travelers, field workers, outdoor enthusiasts, and anyone who hates carrying a charger. The 10000mAh battery originally provided approximately 3-5 days of moderate use, 7-10 days of light use, and up to 30 hours of continuous video playback. This makes it one of the longest-lasting smartphones ever produced. However, after years of charging cycles, battery capacity degrades significantly. Common symptoms include: the device needing daily charging instead of every few days, unexpected shutdowns at 15-25% battery remaining, slower charging than when new, or visible battery swelling. This replacement restores the original endurance, allowing you to continue enjoying the Power 7 Max’s legendary battery life. The battery supports 18W fast charging as originally designed and is fully compatible with the device’s power management system. A fresh 10000mAh battery brings back the freedom of going days without searching for an outlet.
Compatibility Note: Fits UMIDIGI Power 7 Max only. Please confirm your device model before ordering — this battery is designed specifically for the Power 7 Max’s 10000mAh capacity and dimensions. This battery is NOT compatible with UMIDIGI Power 5, Power 6, Power 8, or other UMIDIGI models. The Power 7 Max uses a uniquely large battery compartment; using a different battery model may cause charging issues or incorrect battery reporting.
