Will it affect my iPhone 5's battery life if I use it more often?

it does not. but I would recommend just until your phone battery life is about 30-45 % before charging it up and stuff. other than that its a great device.

For me if I'm using it like normal (Facebook, Instagram ect.) It gives me an extra four to five hours of battery life. But even more if just set it and let it charge.

I've owned mine since Dec 2013. Which means that I can't really answer your question on will it last. What I can tell you is that it's very well made. I've dropped mine twice since Dec without damage to the phone or the Mfi battery. The real advantage is battery life. Take the iPhones battery down to 25% and you can recharge twice more of the Mfi. It is definitely worth the money. If this one fails some where in the future I'll buy a new one immediately. The fact that Apple has certified this should add to your peace of mind.

Depends on the usage if you use it frequently then u need to charge it more often, if a fully charged battery can last like two hours usage

If you run the battery down completely, 3 maybe 4 times. Otherwise, it'll vary alot.

It depends on power from the iOs device. A typical iPhone seems to work for 8 hours or more, in my experience but probably depends a good deal on what other apps you are running.

I get 5 hours of continuous use on medium volume. After that the Bluetooth connection gets faulty and sound gets choppy. That how I know its time to charge

That I do not know, different phone may use different amounts of juice. I know my product didn't last an hr. I personally would not waste my money on it.

I can't answer that question. I do know that I've had it for six months without a problem. Works great with my iphone 5

You won't know. If you use it a lot, you probably should just count on charging it once a week.

I use mine about once a month. Never had any issues with the battery and I have owned it for over a year.

Haven't done any testing as far as # of x-hrs you get but I can tell you this; your phone will get significant x-power. When everyone else's phones are already dead, yours will still have plenty of juice left. My girl's phone went dead the other night @ the club, I took the case from my phone to charge hers, in a few min., she had over %50 charge, Not surprisenly, she was impressed! I dropped mine once, and the case absorbed the impact w/o any damages. I have an iphone 5, so it does fit it

I wouldn't. I heard something about battery life shortened if you don't let it go down and sometimes avoid bringing it back to 100 percent.

We advise our end users to turn on the case when the phone battery is down to 20% to have the most usage of the case. If you leave the case on all the time, you will receive less battery because there is a constant conversion going on between the case and the phone which leads to more energy loss.We hope this helps! If you have any other questions, please kindly contact us via services@myunu.com.

I did use it with my iPhone 4 during a power outage. I had to recharge my phone several times. It was helpful. I have not had a problem with my USB port. Have not had to use with iPhone 5 but the USB is still the same.

As far as I know, it hasn't affected battery life. This isn't a battery, just an accessory. I have had 3 phones (2 probably refurbished) completely stop charging while under warranty. Not sure if using this had anything to do with it.

I think that it really depends on how much you use your phone ....because for me my battery lasted quite a while with the Bluetooth on but like I said it depends
