Hello I'm using a mid 2015 MBP.
My battery lasts 1-2 hours now, I got this text Condition: Replace Soon on the battery icon.
Other stuff are my computer sometimes heats up, gets really slow and fans start working extra hard while working on basic stuff, like running Chrome. I have to close the lid, let it rest a bit then continue where I left off.
Could this have anything to do with battery or could it be something else?
I'm a developer and I need a lot of software open at all times without my computer lagging on me. But I also do not prefer to get one of the new macbooks if a simple battery change will fix this problem.
So is battery condition the reason for poor MBP performance?

Yes, it could have something to do with the battery - and yes, it could be something else. In short, it's not possible to know without examining your actual hardware.
The "Replace Soon" warning combined with the fact that the battery lasts only for 1 hour really means that you should get the battery replaced. It is not going to get better by itself. Nor is unusual - getting 4.5 years of life out of a battery is actually quite good.
If the battery problem causes extra heat - either from the battery itself, charging circuits or elsewhere - it might be the source of your computer heating up.
The source of the heating up might also be something else entirely. For example it could be as simple as a broken or very dirty fan. Replacing the fan could fix the problem.
