Battery Flex for Xiaomi Redmi Go

The Battery Flex / Patta in your Xiaomi is a ribbon cable that physically connects the battery terminals to the motherboard connector. It carries both power discharge current from the battery powering the phone and charge current from the charger replenishing the battery. A torn, kinked, or corroded Battery Flex / Patta causes unstable power delivery, intermittent charging, or complete battery disconnection symptoms on your Xiaomi .

The Battery Connector is the board-mounted socket on the motherboard, while the Battery Flex / Patta is the ribbon cable that plugs into it on one end and connects to the battery on the other. Both need to be intact for stable power delivery on your Xiaomi . If the connector is fine but the flex is torn or damaged, replacing the flex alone is sufficient.

If the drain is caused by poor contact or an intermittent connection through a damaged flex, then yes. However if the battery cell itself has degraded due to age or charge cycles, replacing only the flex will not improve battery life — the battery itself will need replacement. A technician can measure battery health on your Xiaomi to confirm.

It is a moderate repair requiring the phone to be opened and the flex cable carefully disconnected and replaced. It does not require soldering in most cases, making it more accessible than IC or connector repairs. Professional tools and basic repair experience are recommended for your Xiaomi .

Yes — a 7-day replacement warranty covering manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Flex cables that show signs of physical damage from improper installation are not covered under warranty. For more information, check out SAHII's Return Policy.
