It easily lasts 3 days at least and the warnings are the 3 little lights on the side of it.dont bother with the mamba, i own it and believe me the battery life is rubbish, maybe last a day and then flat as a pancake, you dont even get a warning, mine spends most of its time wired lol, mamba = fail
That was the advantage of the g7, it warned you with 10 mins to go, came with 2 battery packs and a charging dock/usb receiver so you could keep playing without any problems. I loved mine until it stopped clicking a few years ago, was given a g9 on rma which just broke and has been replaced with a g500.I think the main reason people don't use wireless for gaming is due to the fact of battery life.
Typical scenario - Playing a match of something, needing to pull off a shot or find some cover and bang, the battery dies.
gg you lose!
I know it has certainly happened to me in the past![]()
