So this is a weird issue. I recently replaced my iPad Pro 9.7’s battery with one from iFixit. The kit was perfect, and I was able to do the repair with the tools provided. However, after this, any time I attempt to use a graphically intensive application (but not CPU intensive application) and only when the smart keyboard is connected, the iPad will shut down, and become unusable until disassembled, and the battery disconnected for several seconds and reassembled. I tried a software restore from DFU mode, but to no avail. Does anyone have any ideas?
I too changed my battery Update (11/06/2020) I have now tried 3 OEM batteries including reinstalling the existing one and all cause the iPad to go into a restart loop I think iOS v14 devices are firmware locked as all show 100mAh on Coconut Plus which probably causes the restart loops. Even completed hard reset and total factory reset to see if it was something else causing it however still stuck in restart loop even when charging. I have accepted defeat and paid £106 to Apple
