Broke a few things on the logic board, how serious is it?

I was replacing the back housing on my iPhone 5 and when I was prying the pesky battery out I broke a few components off of the logic board. I believe they were resistors(?). My phone seems to function completely normal. What damage have I caused and will this lead to complications later on?

Here are a few images that show what came off.

First image shows where one of the black squares broke off like those farther up to the right

second image is one of the tiny components that broke off that look like the ones around it

The first one is Q7, part of the LCD backlight power supply

The second is C355, capacitor to ground for the bias voltage of MIC1

The first one is probably important, without it the backlight may be overloaded or have some other issue

The second one, it's ok

This is why I'm against prying the battery, it's dangerous not just because you may puncture it, but also risk causing damages to other components if you did not land the tool in the right place. Just use the pull tab, if the tab breaks, remove the logic board first, then pry against the metal case when trying to remove the battery. It's less likely to damage the logic board

That's very specific! Thank you for your reply. I hope the first one doesn't cause any problems.

Would I know right away? Everything seems normal for the LCD backlight.

Now that the battery is loosened up from the initial removal it comes out much easier with the tab. I will remember that in the future though, removing it first. I fixit should really suggest that instead. I know I'm not the only one that has damaged their logic board from prying.

I didn't notice at first, you were trying to replace a transparent back case? Looks awesome but seems to hamper signal reception a little bit. Does the GPS still works accurately enough to ensure navigation with the new case?

Yeah I figured why not! I didn't notice any problems with reception and I don't use GPS very often. I only had it on for less than a week. There were some manufacturing defects in the plastic housing that I wasn't happy with. Mainly because the dimensions were off so it didn't fit into my case and the screen didn't fill up the opening snugly so it was prone to allow dust and things in. I went back to the original housing but I swapped out the buttons from a silver ip5 for some modification!
