Hi, I bought a Pixel 3a in September and now a few weeks later, my battery life has gone down. I don't think it is because of the Android Q update, because I noticed it a few weeks after the update. I have noticed that from the first day I got the phone it gets a bit hot when charging. I don't charge the phone overnight or from 0 to 100%. I didn't start using any new apps or anything like that. What could be the cause of this battery life issue? Will the shop give me a replacement Pixel 3a? Thanks for any help.
