The phones are super smart until ...
Smart phones are very smart until they are out of battery - and then you remember that you should receive an SMS or an email.

An appropriate place to stay without a battery is in a tourist adventure with the tent in the mountains. If your lap colleagues have the loaded phones, you can load them from them.

How do I load a phone from another phone?

Using an OTG USB cable, you can charge a phone from another phone or even a tablet, so they have bigger batteries.

Use only in cases of extreme urgency!

The phones were made to be loaded, not to be Portable batteries; That's why it's good to know that a phone can take 500 mAh to the USB port, which means it takes 6-7 hours to charge a phone with a 3000 mAh battery.
Besides the limited current on the USB port, we have some pretty small circuits that can not support the passage of current through the USB port in the long run.

In emergencies, this method can be invaluable!

4. You need to confirm a transaction by phone
5. You must get a confirmation code for whatever
