Whenever I open up the photos app and view videos/pictures in my camera roll the back of my phone gets really warm(at the top underneath the camera) and the battery drains 1% every 30/40 seconds or so.
Has this happened to anyone else? Only seems to happen when in the photos app.
Thanks.
Sometimes the battery starts getting warm when too many apps are open, particularly video apps while charging.
Best treatment is to close all apps and put the iPhone in Sleep mode for a few minutes until the iPhone returns to room temperature.
Heat harms the life of a battery and, if you don't let it cool per above right away, it will only get hotter, which will damage the battery or, as a minimum, shorten its life.

Sorry, but that is not true. It's one of those myths that many believe, and is wrong. Closing apps indiscriminately is generally a bad idea, per Apple's Senior VP of software:

While technically correct, the phone will shut off before the temperature reaches a level that will harm the battery. There is no need ever to cool a phone unless you see an overtemperature warning on the screen.
Lawrence, I beg to differ. The article you referenced nearly discussed having multiple apps open. It did not address iPhone heating or charging at all.
Many apps operate and put a load on the processors when in the background. During normal operation with a healthy phone memory allocation and processing handles the load without a problem. However, as you may have noticed in the Apple Discussion Community, many of us with the iPhone 7 have experienced above normal battery temperatures and are trying to troubleshoot it.
As I mentioned in the earlier response, I have noticed that it occurs when I have several apps open, particularly the video apps, and am charging the phone. The phone seems to cool down more quickly while charging, if I close most of the apps and put it to sleep.
If I simply put it to sleep with many of those apps open while the iPhone is charging it takes longer for it to cool.
The second point relating to heat shortening the life of lithium ion batteries is factual for all lithium ion batteries. Technical articles across the Internet discuss it. While Apple has built a 2-stage protective measure in to warn a user of too much heat, then to shut the phone down, higher than 95° temps still help reduce the life of a battery.
We will have to agree to disagree, then. Apps in the quick launch screen are not running, they are suspended. They are not in background. They are foreground apps and only appear in the list if you have used them interactively. And apps that can run in background don't necessarily show up in that list. They can run in background without being visible to you, even after you think you have killed them. Except for the 3 or 4 most recently used, they aren't even in RAM, and thus can't possibly be running. So there is no way they can be using power. If you think they are, you are imagining it. "Seems" is not a good scientific measure. If you are serious about it you can measure the temperature with a laser temperature probe. They are pretty inexpensive. And you still need to adjust for ambient temperature and control all other factors, such as the fact that the charging rate is not constant; it starts at 1 amp (1.5 amps for iPhone 6 and later if used with an iPad wall adapter), and, at 80%, the charge rate decreases to avoid overcharging. That's why a phone charges to 80% in 45 minutes, but takes 2 1/2 hours to reach full charge.
My current iPhone 7+ has 87 apps that show up in the quick launch app. My battery life is outstanding, and my phone does not get warm. The reason it is only 87 is the phone is only a week old, so I haven't had time to launch the remainder of my 260 apps yet. My iPhone 6, when I retired it, had 160 apps that appeared in the quick launch app. And my battery life was still excellent.
It isn't apps that show up in the list that use energy, it is apps that process notifications, and that run in background. They are not the same thing as apps in the quick launch screen, which are merely pointers to the executables in storage of apps that have run in foreground. And those apps that run in background can run whether they appear in the quick launch screen or not.
iPhone 7 heating up and losing battery really quickly
