Just for context, I have a Samsung Galaxy S8.

Ok, so I ran this in the app and it says my battery life is weak! But, when I ran a third-party app that I think is reliable (phone check and test), it said my battery life was good.

It's true that while on mobile data, the battery life drains RAPIDLY! But, I heard this is the same for those with S20/S21.

I tend to use mobile data a lot when commuting, as I have 36GB every month. But, because of my poor battery life, I pretty much constantly leave it connected to my power bank, while I'm commuting and connected to mobile data. I'm worried that if I get the S21, I'm going to be faced with the same issue... What should I do? Any results/reports I should post?

Connecting to Mobile Data can use more battery resources especially if commuting / travelling as the phone is invariably switching from one mast site to another as you and the phone moves. 

The phone's working harder to maintain a network signal.

The same if network signal is weak from the masts as again the phone is then working harder to keep connected @LiquidSnake 


Current Phone > Samsung Z Fold³ 5G.

36GB? What are you doing to use the data? I have 160GB and rarely use 5GB per month... is WIFI possible while commuting? You could always take advantage of the phones battery saving settings? The S21Ultra seems to last the day while I'm out and about but I do plug in when in the car etc. I do also have WiFi in my car for when I need to upload a lot of data/watch a film or passenger's need WIFI... A good network could improve your issue but I will say, the newer the phone, the better the battery as they're constantly improving the technology...

Wi-Fi is possible, but the speeds on that are trash compared to mobile data. Oh well, guess I'll live with it until my device stops becoming sustainable to use lol.
