Charge 3 battery drains quickly

[tarbat]

For the first 2 days of usage, the battery level on my Charge 3 drops steadily down from 100% to 60%. Then in the next 12 hours it drops rapidly down to 20% and then dies almost immediately.

Is this a fault, as the battery used to last 6-7 days.

I've tried a full factory reset, but still the problem persists.

Hi @tarbat, it's great to see you in our Fitbit Community. I totally understand how you feel about the battery draining issue that your Charge 3 has experienced. By the way, thank you for providing a graph of the battery's behavior and thank you for trying a factory reset before contacting our forums.

In order to avoid any confusion on my end, let me know how the factory reset was performed.

In the meantime, try the tips that are listed in this help article in order to improve the battery level of your tracker. Finally, monitor the battery's behavior during the next 24 hours and see if it doesn't drain fast.

Looking forward to your response.

On the Charge 3, I went to SETTINGS - ABOUT, and selected CLEAR USER DATA

There's little point in monitoring the first 24 hours, as it's only when the battery level drops to around 50% that is then drops rapidly to zero.  I've charged to 60% now, and will monitor over the next day.

@tarbat, thank you for getting back and providing more details. I'd like you to try another way to perform a factory reset. To do so, follow the steps below:

1. Connect the device to the charging cable. 
2. While the device is plugged into the charging cable, press and hold the button down for 15 seconds. 
3. The device turns on and shows a battery icon. Two vibrations occur: first a short vibration, then a medium vibration. 
4. The device turns off.
5. The device turns on and shows a progress bar and short vibrations occur. The progress bar completes. Note: A total of 7 short vibrations occur. 
6. Remove the device from the charging cable. The device shuts down.
7. Important: Plug the device into the charging cable again.
8. Set up your watch from scratch.

After this, keep monitoring the battery's behavior and let me know how it goes.

See you around.

Okay, I followed this procedure to do a factory reset. That's just made things even worse. I charged the Fitbit to 100%, so at 8:47am it said 100%. Within 10 minutes that had dropped to 86%, but I wore the watch all day yesterday. By the time I went to bed it was on 65%, and then sometime during the night the battery run-out. Looking at the heart rate, that stopped recording at 04:38am this morning, so around 20 hours of use.

I used to get over 5-6 days of use. And my wife, with the identical Charge 3 bought around the same time, also gets 5-6 days.

I've also noticed that my display is a LOT darker than my wife's, with both Fitbits on the same Brightness settings (mine of the left).

All these problems seem to start after the latest firmware update. How do I get this fixed?
