Chosen Solution
Hi everyone, Recently I installed a new battery of Ifixit in my iPhone 6S. On my iPhone runs the IOS public beta 11.3.5. (number: 15e5211a) In this beta the battery ‘maximum capacity’ and ‘peak performance’ can be read out via ‘settings’> battery> battery condition. My old battery gave 76% at ‘maximumcapacity’. However, the ifixit battery gives a error message an indicates a ‘-’ value. At ‘peak performance’ shows the message: ’the iPhone can not determine the peak performance; a certified Apple service provider can repair the battery ‘. At the setting ‘Batterycondition’ it reads: ‘Repair’ When I installed the new battery I calibrated it. I also tested the new battery immediately after installation and it has the maximum capacity and zero cycles, so no problems. Ifixit suggested a ‘hard reset’ and/or a software restore. Both suggestions I followed but no results. Has someone indentified this problem and is it possible that Apple / IOS does not accept a non-original battery or could there be an other problem? Thanks everyone
This could just be an iOS beta issue. To be certain, use a battery utility, such as coconutBattery (for Mac) or 3uTools (for Windows). It will tell you what the health of the battery is. If these tools don’t communicate with the battery, there may be an issue with the gas gauge line, either in the battery or on the logic board. There is a tiny component right above the battery connector (length-wise), the second one from the right. If it got pried off the board, it will not allow the battery to communicate the health status to the CPU.
