Don't worry, everything will be perfectly fine. High power consumption is an old problem in Canon cameras that use AA batteries. The reason is that the longer the camera is used, the higher the cut-off voltage. I won't explain it in detail, I will just say that the solution. is to use a lithium iron phosphate battery with a higher voltage, 3.2 volts. In actual use, a lithium iron phosphate cell is connected in series with a pass-through fake battery (two lithium iron phosphate cells plus a fake battery on Taobao). costs 20 yuan and the corresponding charger costs 30 yuan). The poster can go to Zhongguancun online station and search for "lithium iron phosphate", and many users will have experience using this battery. Remember that a lithium iron phosphate battery must be connected in series with a battery factice and that you should not insert both lithium iron phosphate batteries into the camera. I have answered similar questions many times on Baidu, and they can all be answered very well. http://zhidao.baidu.com/question/151781919.html
