New phone might be causing issues with my WiFi

I bought a new phone almost a week ago. It's a Lumia 635. I've noticed in the past few days that whenever I have it connected to my WiFi, Battlefield 4 would get high latency variation and sometimes high ping. I feel that since I get issues in that game, my phone might also interfere with other online stuff. I've tested other phones (my mom's iphone and my nephew's android) and none of them gave me issues. My old Lumia 620 gave me no trouble when it was connected. The kicker here is this new piece of information that I discovered: If I have my new phone connected to a charger while it's using my WiFi, my issue becomes fixed. I don't understand that.

What I want is to be able to use my phone around the house without being disconnected to my modem (an Arris DG860) or connected to my charger at all times. I need help figuring out what's the exact cause of this problem. I've tried turning on/off the router, did reset and hard reset, and looked through my phone and disabled some stuff that might be an issue such as disabling photos from uploading to OneDrive. It's driving me crazy that I can't find the culprit. I want to figure out if it's a certain app on my phone that's causing the issue. I fear that it might be hardware. I dropped my phone a few days ago and it cracked the glass. Could it have also been damaged on the inside? I took the case off and didn't notice anything wrong with the phone. I'm hoping it's something else. Thanks for reading.

My brother upgraded to one of those.
He does lots of recorded videos and photos on his phone.
Problem was his first bill was outrageous because he went over his data limit. For over three years he had never went over his data limit.
The phone is automatically set to upload everything to the cloud and play back everything from the cloud. even if it is local storage it will play it back from online storage.
When you plug the phone in it turns off Auto syncing so the battery will charge faster.
Now the real kicker(unless they have changed it) you have to take the phone in so they can install an app so you can turn of auto syncing and cloud playback because they are not in the phones default menu.
Sorry to have to be the one to give you bad news.

Thanks for the information. I'm positive that I disabled cloud syncing for my photos and videos. I found an option to disable it, but maybe it still auto syncs. If I take a picture and don't find it on my OneDrive account, does it mean I do have syncing disabled?

I'm thinking now that maybe it's either my modem that's acting up or Battlefield 4 is just very sensitive about latency. I tested my nephew's android phone again and I did get warning icons about latency, but they weren't as persistent as when I have my own phone connected.
