Last November, I lost my Android phone to theft. It happened at the most unexpected place—in a laboratory, guys!
The method the thief used was familiar to me—not through experience but from a discussion with a smart guy I met earlier that year. He had told me that to take something that belongs to someone, you have to introduce your own property into the exact same space where the other person keeps theirs, and then while leaving, you take the two items—your own and that of the other person. That is the trick that the young man who took my phone used on my friends, whom I asked to help me watch over my charging phone while I got our workbooks from the class rep.
I was very sad when I got back home without my phone. I knew it would be difficult because I would have to use my iPhone all the time, coupled with the fact that my power bank is old and can't last more than two days without electricity.
Now that is the only thing I hate about iPhones: the weak batteries. No matter how you try to protect it, it still can't be used without having a backup plan—a power bank.

I wasn't able to get another Android phone until this year. I was happy because the stress of charging a phone several times a day and moving around with power is gone. As we all know, good Androids don't require a power bank even after two years of usage. However, to achieve this, there are precautions we must take. I guess this must be what
Digi-Prompt wants to know by asking,
"Is there some hack to managing your devices' on-time?" The first day I got my new Android phone, I made sure I charged it to its absolute percentage before operating it. This simple act is very important as it determines the maximum rate at which your battery will function.
The other things I'm doing to manage my battery health on time include setting my phone to stop charging when it reaches 98% and switching off my data when I'm not using it and turning off the data for the apps I'm not using, avoiding frequent charging in a day, and being mindful of the quantity of images and videos I save in my gallery. I also try not to use it to watch a movie every day—as my neighbor has a kid who prefers cartoons to his homework:)
Lastly, I've noticed that introducing any device to power bank or solar power weakness the battery.
***If you're curious about how long my devices last...***

I've had a consistent electricity supply recently, so I haven't yet experienced my Android phone's battery at its lowest. I can only assume that it can last two days if I'm not over-using it. I am hoping it maintains this reputation for at least a year.
And as for the iPhone, the battery health has dropped to 85%, so i can't use it for 8 hours without charging. The camera, however, remains a reliable tool for capturing moments:)
Thank you for reading.
I took all the images myself.
