[IMPORTANT] Clarity for all the battery problems!
Since im reading so many topics about problems with replaced batterys and after iOS 11.3 made the whole thing clear for me, I decided to open this thread and light up your issues!
It all started with the replacement of my iPhone 6's original battery; I got the feeling, that the new one I bought from iFixit drains faster than my original one back in the old days. I also got the issue that whenever my iPhone is out of battery and I'm trying to restart it, it falls into a bootloop instead of showing me the battery or "charge-me"-icon.
Yesterday iOS 11.3 came out and if you using a non-original-battery, you shouldn't be able to use the new "Battery Health"-feature, because it just supports original batterys from Apple.
This and all the topics i will link you now, made it clear for me, that non-original-batterys (regardless where you got it from) doesn't work like original ones.
1.) [iOS 11.3] Battery Health - Replaced Battery?! (This topic includes pictures!)
2.) Boot loop when battery is empty (One of the earlier topics after the problem become public! See last post especially!)
+ alot more topics you can find while using Google!
What can I do now?
If you haven't replaced your original battery already, I just can recommend you to go to Apple and let it replace as long as they have the $29-campagne! If you replaced it already, you can ask them for help too or trying to get a OEM-battery and hope it works fine!
I hope this topic made all the issues a bit clearer and helps others aswell!
