oh really? because for tons of month the average of time it takes to do a battle for mobile players has been between 8-10 seconds being lucky and the worst part of that is if you stay in the GbG map for some minutes, it starts becoming more laggy to the point were you do 1 battle every 15 seconds.
and let me asure you that I do not have a bad cellphone, a Xiaomi redmi note 7. a mobile phone that can even run Genshin Impact. imagine most players who do not have a good cellphone like the one I have and the one I have it is not the best in the market, is just a decent one but not a very good one.
Not the phone is bad, brain is ...
8-9 seconds on phone for a fight? i think on a phone with quad core mediatek and one gb of ram or on a potato.
Again You barely know what You say.
At my best at 0 atrition I could do 33 fights/minute in GbG on a pc with Logitech g502 hero 25.6k dpi sensor, and someone else on his phone did 32 fights/minute with the same contidions, it will be a difference at very high atrition from the moment You have to change army units on phone, still, not more than 4 seconds with drag-drop per fight needed.
Now phone have the advantage, I am lowered to 27-28 fights/minute IF IT'S NOT HAPPEN to hit the diamond confirmation in which I lose some time to close the boxes ...
In GvG I was able to do around 41 fights/minute with the trick of centering the dialogue boxes and not changing -too often- the units between fights.
Now is worse, many quit GvG, a macro/script doesn't care where the boxes are, it will fight with the same speed ...
P.S: My computer have i5 9400f with a aerocool cooler, not the stock one, 16 gb of ram at 2666 mhz, powercolor Radeon RX 580 8 gb version clocked on it's full power and adata xpg ssd nvme pcie x3.0, 3.2gb/s or something like that according to their webpage and Windows 10 21h1, browser used at that time was brave with the high performance gpu mode activated via windows and few basic changes via "flags" related to gpu rasterization to improve the smoothness in loading/playing games via any chromium based browser.
My phone is trash, Lenovo S5 K520, 4gb ram and snapdragon 615, it can handle the game very well, but in GbG is slow, but even so, I can do fights faster than what You said, it needs 6 seconds for a fight for me, with loading and searching units, if is at 0 atrition it takes around 3-4 seconds between each fight with the loading ...
