You might at well carry a power bank rather that put on this case ...
on August 29, 2017
This product shipped to me in a package that explained a few things about using the product. The instructions were overall not very clear so I had to learn by using the product.
Here are some of my observations:
. Once the battery case was installed, I put this on charging. The blue light indicator (4 of them) came on. Some of them stayed on perhaps indicating that the case is charged to certain extent, and some of them were blinking indicating that the case is still charging. So if 2 are on and one is blinking it would imply that the case is at least 50% charged.
. The charging took a long time - about 7-8 hours for all the blue lights to come on without any of them blinking. The phone was also charging in parallel but in these 7-8 hours it only reached from 50% to around late 80s. It didn't go to 100%. I lost patience and plugged it out. I charged to phone separately to 100% which was quick
. Thereafter the phone was in use. It kept on discharging at its usual pace with the case being on. When it reached around 10%, I pressed the silver button at the back which lit up the 4 LEDs. Three were on and last one was blinking perhaps indicating that the case is discharging and the phone is charging. The phone charging symbol also came on.
. It took about 2 hours for phone to reach around 79% and by that time the battery case was completely discharged which means that the case doesn't hold the charge for long time and keeps discharging even though it's not in use. The second point is that the case might not hold enough charge to get the phone from 0 to 100%.
This is the first phone battery case I have used and honestly found it not quite useful. There's really no difference between carrying this case and carrying a powerbank so why would you keep the case on and make the phone heavy
In terms of protection, I didn't drop the phone so not very sure. But honestly, it was barely covering the phone on the sides so the protection wouldn't be as much as the simplest of cases
