Designed for LG G8 ThinQ 820 series

This Cameron Sino replacement battery fits the LG G8 ThinQ and its carrier variants including LM-G820QM, LMG820QM7, LM-G820TM, LM-G820UM, LMG820UMB and G820N. It restores full battery life and functionality for owners of these specific models. The battery is built from high-quality cells and engineered to meet or exceed original manufacturer specifications.

Model-specific compatibility list

The single specification that decides fit is the exact model number printed on your device. This battery supports G8 ThinQ units labelled LM-G820QM, LMG820QM7, LM-G820TM, LM-G820UM, LMG820UMB, LM-G820UMB and G820N. Buyers with any other LG handset, including different G8 regional variants not listed here, cannot use this part.

Sustained daily discharge behaviour

High-quality cells deliver consistent voltage across a full day of mixed use rather than only during short bursts. The construction supports fast charging and minimises the need for frequent recharging while maintaining stable operation. Users who need extended runtime for continuous navigation, streaming or tethering beyond a single day should consider a higher-capacity power bank instead.

Questions about this item

How does the 820 mAh capacity affect daily runtime in an LG G8 ThinQ?

The battery is built to match the original specification so the phone delivers the same screen-on time and standby life it had when new, supporting fast charging to reduce downtime.

What connector standard does this replacement use and what does it limit?

It uses the LG G8 ThinQ's proprietary flex connector, which only fits the listed 820-series variants and prevents use in any other handset.

What physical steps are needed to fit this battery into the phone?

Remove the rear glass, disconnect the old pack, lift it out, seat the new cell in the same cavity and reconnect the flex ribbon — no soldering or extra brackets required.
