Phone charges but the home button and microphone do not work.
I just installed a new battery. After reassembly, the home button and microphone are not working. Any assistance would be greatly appreciated.
Thank you!
Is this a good question?

Is the phone charging? Headphones jack is working? Answer this first.
Second, did you disconnect the lightning connector during the battery replacement? Did you nick something on the board, and/or did you pry at any time between the battery and the logic board, especially next to the charging port connector? Also tell us.
Third, as a quick troubleshoot, disconnect the screen, disconnect both the battery connector and the lightning (charging dock) connectors. Clean the charging dock connector on the board using a cotton swab and 90%+ isopropyl alcohol, then reseat gently and make sure everything is connected properly. Test the phone again, is the mic working? is the phone charging? Is the home button now working?

The phone is charging and the headphones are working.
I did not disconnect the lightning connector.
I don't believe I nicked any thing and did not pry at anytime between the battery and the logic board.
I will try disconnecting the screen and other components tomorrow. It is late and my patience is done for the day.
Thank you.

I had the same problem after changing the back panel and the display. In my case I had to make 2 jumpers on the main board. 2 very tiny resistors were ripped off the main board. FL49 for microphone and FL5 for home button.
The blue marks represent the battery connector.

Hi,
I have the same problem. How can I fix it?
I can't know for sure if your problem is exactly the same as mine. I have training in electronic engineering and I have the proper tools for a fix like this. You need at least a soldering iron with a very fine tip and magnification glasses or better, a special microscope. If you do not have an idea about what a resistor is or what a soldering iron is, then you definetly should not do the fix. It is better to take the phone to a repairing shop and show them this post so they can check if your problem is the same as mine. If you heve repaired your phone, come back here and tell us what was the problem and how you managed to fix it. Maybe some day someone will be able to fix his phone by following your post. Shared knowledge is what helps humanity go forward ;).
mzaferyahsi, ioanflorea's answer is correct if you did disturb anything on the logic board. I also highly agree with him that you need excellent skills and proper tools to fix something this small. Personally, I prefer replacing missing components by getting them from donor boards over using jumpers.
However, If I were you, I would start with a quick troubleshoot like the one above to try and rule out the simpler issues such as improperly seated connectors and cables for example.
dude ur r a life saver.. it worked for me
That's it! I posted my advise below.

I had same problem that home button & microphone didn`t worked, so I followed the scheme and asked professional to jumper damaged filters.
Issue was solved BUT another troubles occured:
Accelrometers does not work anymore, so I am not able to switch camera or Safari to landscape.
My iPhone does not ringing at speaker when I try to call there (but it is ringing on headphones).
Guy who jumpered filters under microscope saw that few other SMD capacitors are also damaged, so now I am looking for scheme to describe their values so we can proceed another solution (if any available). Phone restore also did not help.

That's it Ioan Florea!
I had 6 parts(resistors and capacitors) ripped off and stuck to the insulation sticker. After a master soldered it back(for $17) all works again. Hooray!
P.S. I'm pretty good with soldering iron, but this parts is too small! Without microscope I could nothing to do with it(and don't advise to you).
P.P.S. Don't try to hook up the battery from side of charging and dock flex cable connectors!!! Correct way:
