Performance decreased with low battery
Hello
I have a Retina macbook pro 15" (late2013) OSX 10.9.4 , I've never discharged below 10% before, but yesterday I did and I noticed that my macbook begin to slow (UI lag) , many tasks stop responding (I have not saved my work yet 😟) ,though basic task can be opened but very slow (Finder Safari etc.) , at first I think this should be Ram error problem because I turned it on and did not shutdown almost a day so I restarted it but result was the same, this problem was solved when it connected to adapter for a while , now I think that low battery might cause this , I start to wonder whether this is normal or I need to something to be replaced.
Thanks
