I don't know if anyone else why plays on this has had this issue, but whenever I load up Openfront.io, the website absolutely guzzles my battery life. Most recently in a singleplayer game, the estimation my device gave me for my battery before loading it up was about 4 and a half hours, yet when starting the game it drastically lowered to 1-2 hours.
Unsure if its just the sheer number of calculations needed for all the bots, or if its just performance issues on my end, but i thought i should bring it up.
