Can You Develop Film in a Jägerbomb?

Analog photographers love trying new and unusual things. Whether it’s shooting on expired film, skipping film altogether, or developing film using odd ingredients. Sweet Lou Photography opted for this last type of experimenting and developed his film inside a Jägerbomb. Did it work?

New Galaxy S26 Edge battery leak keeps piling on the bad news

Ryan Haines / Android Authority TL;DR A Chinese regulatory filing suggests that the Galaxy S26 Edge could have a smaller battery than previously rumored. The listing hints at a 4,200mAh battery rather than a 4,400mAh battery. This would still be an improvement over the Galaxy S25 Edge. The Samsung Galaxy S25 Edge might be the most polarizing Android phone of 2025. The device has a very slim and light design, but this form factor comes at the expense of battery life.
