I just started using this phone on March 23rd. The battery life was great, but recently it's been performing like my 6P. It will lose 10% in about 40 minutes. Up until at least the 1st or 2nd of April. I could be on the phone for 40 minutes watching videos and doing just about whatever and I'd be surprised to have only lost about 3-5%. I haven't done anything all that different. I've updated the software and I've gotten rid of over 50 apps, but I almost want to say this came after I noticed the battery draining faster. Maybe I'm using it more now, but I don't think I am. It seems to just not be performing as well as it once did. It's still good, but it's annoying to have had such great battery life before.
