Can't boot since photo with flash after battery + screen replacement

I have made a screen replacement on an iPhone 5 and changed the battery. It worked as usual afterwards. The next day when taking the first photo with flash turned on the phone immediately shut down and would not boot since. There is a similar thread here in the forum, but symptoms are different.

I have tried:

-hard reset by holding 'home' +'power' buttons for extended time

-long charge

-checked that battery is still sitting in place

-checked other cables inside

Since the phone shut down exactly when using flash I assume this is either software caused or because the new battery is faulty. I have contacted the seller of the battery but would like to hear if anyone would suggest other explanations?

It is a battery quality issue. It is when the flash during taking photos is taking too much power causing the battery voltage to drop under the minimum voltage for the phone to stay on.

You may notice that this may not happen when the battery percentage is full or the phone is plugged in.

Solution to this is to look for a better quality battery. Right now I'm actually searching for one (iPhone 5C, shuts off on camera photo flash and sometimes on lower 20-50%).

Thanks for your answer so far. This is what I have assumed so far. What confuses me with this explanation though is why it won't turn on again afterwards.
