How do you save the memory of an iphone 5?

Around 48 hours ago, my sister woke up, picked up her phone, and then, because she wasn't really aware of what she was doing, dropped her phone in a cup of water, and then went back to sleep without even noticing. Probably about a half hour later, she officially woke up this time, and then took her phone out of the water. She tried keeping her phone in rice, but it still won't turn on, or charge. She did some research, and it costs a ton to get her phone fixed, so I think she's just giving up, and thinking about getting a new one. But she has all of her photos and games and apps on their. I was wondering if their was any way to save her phone and all the memory on it? I thank you for any information you can give.

It's toast.

Sister isn't too bright. She had ample opportunity to back up her phone.

If she had a backup, you could use that to recover to that point whether it be iCloud or iTunes.
