Help/Support iPhone Shuts Down at 15%-20% Battery Left

[Rook 549.4k iPad Pro (2nd gen) 17.4 Donor]

Hello,

 

So this has been happening to me the past week and it's getting frustrating as it just randomly powers off when it reaches 20% or lower. And when it powers off, I cannot turn it on again because the "No Battery" screen comes up telling me to plug in the charger.

 

But, after waiting a few minutes I can turn the iPhone on again and see my battery is at the same percent it was when it powered down. Then after another few minutes it shuts off again and repeats the above.

 

I believe this started happening after installing WatchDog Pro but I'm not so sure if that can cause something like this.

 

Anyone else has experienced something like this? The iPhone is on iOS 8.4.

It's your battery, had this happen to many people.

 

I could do it for you but you live know where near me.

 

You can buy the battery from eBay or something.

Really?

 

The phone is new

 

I guess that cheap portable battery charger must have killed it
