The battery on my phone has been lasting noticeably longer since I uninstalled my work email account. I knew I was getting bombarded; but that really highlights the situation. I still get a lot of personal emails across my various accounts too. But they aren’t as long to read since they aren’t a long chain of forwarded emails. It wasn’t the sync that was causing the problem. It was the screen being on for a long time while I was reading and sometimes responding.
