There seems to be a huge issue with overheating in this new update. The device I'm currently using is an iphone SE 2020. Before the update there was no heating issues whatsoever. Now it gets so hot it burns my hands and forces my phone to shutdown until the battery cools again. It now also drains the crap out of the battery, which it didn't do in previous version of bedrock PE. In an attempt to fix it I delete the app and re-installed. Nothing changed, except it took longer to get obscenely hot. I noticed that as soon as I logged into my Xbox live account my phone would suddenly get over heated quickly. This is not even playing in a world, just literally sitting on the menu screen. I cleared my phone and restarted it, played on other app games, so this issue only seems to be with Minecraft PE.
