Thinking of upgrading to a 7, probably Pro when Black Friday deals hit. My 6Pro battery life sucks shit, I’ve replaced the battery with an OEM one and not much better. I use my phone throughout the day, but most of it is streaming with the screen off. Always needs to be charged. Normal amounts of random app use and browsing.
Battery usage is very subjective, so what one might consider “light usage” might not be for someone else, but most of the comments in this thread seem to suggest that your battery experience is really the outlier here. It might be worth it to ask to send it back to Google to get a replacement (or have them replace the battery) as chances are there’s definitely something wrong with your battery.
