System ui errors when below 15% battery

[AC Question]

Please help me. I've already do everything. Clear cache, hard reset but still the same. Everytime my battery below 15% the same error came out. But, when i've charged my phone, that massage errors dissapears. Only when below 15% battery percent & all call & massage are not functional when the error came out. I cannot answers & replied massage. Please help me. I have no other way. Maybe you all can help my problem. I used iphone 6 plus korean clone & android 5.0.

Welcome to the forums. It's difficult to fix problems in that kind of clone phones. Just in case, check in the battery settings if there's any battery saver option and make sure it's disabled.
