Macbook pro 2012 slow after battery died

I'm gonna jump to the question real quick. I've tried all method including reset PRAM, SMC, turn off auto adjust brightness (I read here some people experience the laggy UI when turn it on), set different resolutions, delete windowserver or-what-ever plist. But the problem is still there.

I noticed that my MBP is laggy when resizing windows especially web browser, typing (it's like I've already type bunch of sentences and it appears the whole sentences after being frozen) and scrolling.

I know it good to replace the battery now (as the battery condition is replace now) but not any time soon because I really need my lap atm and I can't even for the authorized apple service center for one month just to replace the battery. So is there any way I can do to solve this ? I've researched all around the Internet and found out some dudes facing the same problem because of Intel Speedstep but it is only exist with the 2011 or earlier model with Maverick is on (I'm currently running El capitan on late 2012 rMBP).

Thanks in advance.

MacBook Pro with Retina display, OS X El Capitan (10.11.4)

I don't know what seems to be the problem, I looked up in Intel gadget and it says IA:1.2GHz GT:0.35GHz what does it mean ?

Isn't it supposed to be 2.5GHz ? guess somehow my lap reduced its speed that's why I'm suffering slow on web surfing

btw I accidentally pressed the correct answer button to see what it does but I don't know how to un-do that

It is 2.5 GHz, click on "Technical Specifications". Other than that the report seems exceptionally clean.

Let's try to trouble shoot the browser...

Force Quit Safari ( command + option + esc keys). Then, Relaunch Safari holding the shift key. Then, turn off Safari extensions (Safari menu > Preferences > Extensions)

As far as your question about marking the post solved, that happens a lot. Unfortunately, there's no way to undo it.

I mean the current speed not the technical speed

I use chrome. To be clear, scrolling on safari is perfectly fine but resizing isn't, opposite for chrome, scrolling react a bit slow but resizing is faster than on safari (I can feel the delay it's like 0.2s or so) and typing on the two browsers are the same, too slow to appear what I typed

I noticed that when my battery is dead, I tried fresh reinstalling the os also but that wouldn't help.

I've tried to type in note to make sure it's the browser problem and I can tell that it's way faster than on browser but still slow reacting to my typing pattern, maybe it has a problem with I/O task

Did you try the force quit/restart shift on both browsers?

I/O Error, where are you getting an I/O error?

I mean I guess it has a problem with cpu receiving I/O task, not a specific error anw I tried force quit and shift restart, it's smooth like 10 seconds and back to slow again.
