EOS Rebel T6 Short battery life even after battery replacement

[VCul26]

I have a canon rebel t6. It was new in 2018. I've never had any issues with it, but this past year the battery life has depleted. I purchased replacement chargeable batteries, but it hasn't fixed the problem. They last about an hour. Can anyone tell me what's causing this?

Thank you!

Does it happen with all lenses? Does it happen with the lens off?

All of the above

Greetings,

Are you using Canon brand batteries? 

Also make sure you have wireless disabled if you aren't using it.
