Overnight battery drain due to bad signal on AT&T?

[arrrgh]

I have had massive overnight battery drain, roughly around 40% in 8 hours. The phone seems to be in deep sleep most of the time but for some reason cell signal quality drops to "orange" during the night.

The phone is in exact same spot the whole time. Signal quality changes to "green" as soon as I start using it.

Anyone seen similar issues and do you think the battery drain is really due to the signal quality changes?

Try clearing the cache on the phone. I had the same issue. I was pissed off that my brand new phone was draining 10-15% every hour while idling. After I cleared the cache, it fixed the issue. After doing some research about it, it seems that after the update, you should clear the cache.

How to clear the system cache on OnePlus 5:

Turn off the OnePlus 5
At the same time, hold the Home button, Power and Volume button
Wait until the phone vibrates and the OnePlus logo shows up
Release the Power button, but still hold the other buttons
Now highlight the Wipe Cache Partition option and use the Power button to select the option
Go down to Yes and use the Power button to select it
Press the power button to select Reboot System Now
The OnePlus 5 will now reboot and clear the system cache

Cheers, I wiped the cache this morning so I'll see if it helped tonight.

I have the same issue, except I'm from India (so not due to At&T) and my my signal strength always is green. But, my battery just drained 33% overnight. Thought of placing a replacement on Amazon but came across this post.Will try and update. Thank you!
