Thanks for the suggestions. I did indeed have Home Assistant with the Tapo Camera integration so I've removed that, but I haven't seen an improvement as a result. I've also removed the camera from my Wifi network and re-added it but again to no avail. 

I do notice that the camera is consistently considered the slowest connection of all my devices according to my router's overview, despite the fact that the camera is roughly 2 meters separated from the router (both are at the front of the house).

In the past few days I've seen its battery go down tremendously again and this time the app doesn't show even a single wake up time, whether it was filtered or not. In fact, in the past few days I've only had three clips being created.

I enabled diagnostics on the camera and had a look through the file with Claude which analysed the following:

=========

Looking at your diagnostics from Feb 27, there are several clear indicators of what's draining the battery:

1. Extremely frequent wake-ups
This is the biggest issue. On Feb 27 alone, the camera went through dozens of boot cycles, sometimes only minutes apart (e.g., 10:04, 10:10, 10:25, 10:30, 10:36, 10:42...). Each wake-up draws significant power — the camera has to power on WiFi, connect, initialise the video pipeline, mount the SD card, etc.

2. Frequent live view access
Many of these wake-ups are triggered by someone (or the app) connecting to view the feed. The logs show repeated P2P and relay connections from your local network (192.168.0.159) and your external IP. Each time you open the live view in the Tapo app, the camera fully wakes up. On the morning of Feb 27, there were clusters of back-to-back connections — some sessions lasting only a few seconds before disconnecting and reconnecting.

3. Watchdog timer resets
Several entries show mcu_rst_reason=2 (WDT reset) and watchdog failure counts like wd_fail:0_4_1. These are abnormal reboots where the camera's processor wasn't responding in time, forcing a restart — wasting power on an unproductive boot cycle.

4. Battery level over the day
You can see the drain directly: the battery dropped from around 18% (early morning) down to ~13% by midday, largely driven by all those wake cycles.

5. SD card corruption warnings
Every single boot logs a FAT-fs warning about the volume not being properly unmounted. This suggests the camera is shutting down abruptly rather than cleanly, which could indicate the power-down sequence is being cut short.

=========

This will be a little bit distorted because this morning I was indeed actively looking at the camera while diagnosing. That said, given the filesystem warnings I did format it and I'll see what effect that has.
