Hi, I've observed my battery drains very quickly when I'm roaming outside my home country. I can't understand why. This is before and after I updated to One UI 6.1. Didn't seem to make a difference. Does anyone experience the same thing or have a fix?

Hi, I suspect this is due to the weak roaming connection. How about if u connect to a wifi network? Does it drain fast too? If it doesn't, then highly likely it's the roaming data connection.

Hihi, thank you for the response! I first noticed it on the plane when I was on plane wifi and started seeing my battery drain fast 10-20% in 20 minutes. Not sure if plane wifi makes a difference but I also noticed it after I was in a taxi on the way to the hotel. So I'll keep observing.

But also, why does roaming data connection drain the battery?

One possible reason is that during no service, it keeps scanning for a service provider until it finally connects to a service provider successfully. So during this period, it consumes a lot of the battery power. May I check if u turned on airplane mode while u were using the airplane wifi?

Actually this does make sense. I did turn off airplane mode after landing. Plane was stuck on tarmac for 30 minutes and usually mobile reception while planes are on the tarmac not close enough to the terminal usually isn't great. So maybe it was scanning for a bit. I'll continue monitoring next few days while I'm out of home country!

Okay do monitor for the next few days. 😊 Normally, phone signal should be 3 to 4 bars for stable connectivity. If it reaches 2 bars and below, the phone is likely to be scanning for better network reception and this could cause the battery to deplete faster than usual.

Did anyone get anywhere with this issue? 

I'm experiencing exactly the same thing.
