Imo, it could be because you're on data at work. Usually at home, WiFi is consistent which means it is less likely to be "hunting" for a strong network connection Vs when you use data by your carrier. It takes more energy to keep a stable connection and you could also be in low connection zones that cause your phone to constantly hunt for a good connection - consuming battery in the process. This is why you should stick to using WiFi as much as you can.
Also when u are outdoors screen brightness goes to full that's y the battery won't last long but when u are in indoors screen brightness is on 10percent
Yeah, that can also be a factor. Honestly, it's more than just connection and screen brightness too. There's so much we can add that factors into the battery consumption haha.
