Canon Might Be Working On A Better Battery Charge Indicator, Patent

Canon Patent

Will this Canon patent come to your next Canon camera? Maybe not, but it might on the one after your next.

Canon patent application 2021-114887 discusses methods and technology to show charges of both the internal and external battery. From the patent literature:


To notify a user of a relation between a full charge capacity of a battery of an electronic device and a remaining amount of a battery of a battery device connected to an electronic device easily.

[Means for solving]

The battery device (100) has a display means for displaying information indicating a result of calculating a residual amount of a battery of the battery device based on a full charge capacity of a battery of an electronic device connected to the battery device.

These Guys Re-invented The Camera Battery, And It Looks Promising

Camera Battery

We all know the issue with the camera battery, especially the pros: you carry around many batteries to not run out of juice for your camera(s). A new Kickstarter project tries to tackle this from a new angle.

X-tra is a group of photographers and engineers who are into NATGEO photography and videography. They are behind the X-tra battery we are featuring here. At a glance:

  • 2X Capacity
  • Charge Level Indicator
  • Quick Reload
  • Supply power via USB-C
  • Power bank Feature
  • USB-C Fast Charging
  • Grip Extension

The X-tra battery is compatible with the following Canon cameras: EOS R, EOS R5, EOS R6, EOS 5D IV, EOS 5D III, EOS 5D II, EOS 5Ds R, EOS 5Ds, EOS 6D, EOS 6D II, EOS 7D, EOS 7D II, EOS 90D, EOS 80D, EOS 70D, EOS 60D.

You can support the X-tra battery project on Kickstarter.

This is how the guys behind X-tra see it:

For many photographers, power is a major struggle. If you’re shooting video or working in live-view, a battery charge never seems to last, so you’re stuck carrying 3 or 4 batteries in your kit. X-tra battery is here to solve that problem and simplify your kit with one revolutionary accessory.

Think it’s hard to get excited about a battery? For most gear heads, power solutions and batteries have generally been the least sexy accessories there are, until now. The X-tra battery solves multiple photography headaches and even offers some solutions you didn’t know you needed but soon won’t be able to live without.

For starters, in terms of power capacity, the X-tra holds 3,700 mAh, which is two times the charge of Canon’s LP-E6. Previously the only option for a double capacity battery was to use two separate batteries within a battery grip, so lots of photographers will potentially be able to eliminate an additional piece of bulky equipment. The X-tra is a full-size camera battery, similar in size to the battery found in the Canon 1DX. The physical profile of the X-tra extends just beyond the bottom of the battery compartment on compatible camera models, providing a solid grip for larger hands and a comfortable, extra secure feel. Because the X-tra requires the camera’s battery door to be removed, you can quickly change out batteries with one hand without fumbling with a battery compartment door. When it is time to swap batteries, it’s a super fast and easy process. Just press up on the battery to release it and replace it with a fresh one.

Wireless Charging Might Come To Canon Cameras In The Future


Canon patent application US10375639 discusses technology to wireless charge a battery. Looking at the patent’s images, it seems that the patent clearly refers to wireless charging a camera’s battery.

Patent abstract:

A power transmission apparatus includes a communication unit that executes communication with an electronic apparatus, a power transmission unit that wirelessly supplies power to the electronic apparatus, and a control unit that controls communication and power supply to be executed alternately, wherein the control unit adjusts communication power of the communication unit and transmission power of the power transmission unit and/or a length of a communication period and a length of a power transmission period, so that an average magnetic field intensity does not exceed a first magnetic field intensity in a predetermined region throughout the communication period of communication executed by the communication unit and the power transmission period of power transmission executed by the power transmission unit.
