Your iPhone will turn off with the 50% charge? Check the quality of your power supply
According to what reported by the chinese sources, the problem of the battery of the iPhone 6 and 6s, it seems that it is not caused by a manufacturing defect, but by the power supplies of third parties, of a very poor quality.
A few days ago we told you about a recurring problem with the battery of the iPhone 6 and 6s, also reported by the China Consumers Association. After the recent analysis, it seems that the cause is finally coming to the surface.
The power supplies of third parties are often implemented in a superficial way, to counteract the higher prices of Apple, the costs really reduced. As discovered by AppleInsider, these can cause permanent damage to the circuitry that regulates the charge level of the battery inside the iPhone. This defect causes a false picture of the level of charging of our smartphone on any version of iOS. Therefore, if your device turns off alone, with 50% of the charge, be sure to check if you are indeed using a power supply quality.
This would confirm the “innocence” of Apple in respect of this very common problem, in fact it has been shown that all of the faulty devices analyzed, have been loaded through the power supplies of poor quality.
Apple then will consider this issue as a cause that is external and will not be made free repairs, even with the warranty still valid.
