Over the last several days I've seen larger than expected battery usage when my S2 (Nougat) was sleeping (10% rundown as opposed to usual 1% at most overnight). Both Gsam and the built-in usage monitor indicated significant CPU usage by the Photos app, this even though I haven't used the app for some time nor I have I added new pictures or media to the device. I tried clearing cache and data but that had no effect so I disabled it. Problem fixed. I use QuickPic Pro for picture management so I don't miss it but I was wondering if others had seen similar behavior. I don't see it on my Galaxy S7 Edge.
