Haven't had good battery life since the AUB6 update I think anyway. Can't remember the exact build but was happy with battery life. Since the May update standby drain is really high. Screen on drains every few min. Never used to be like this. Used to be 1% every 10min the display is on which was reasonably good. Samsung need to stop focusing on camera updates and fix the bad battery life. Disappointing for a 5000mah battery. All apps in deep sleep. Auto sync off. Location off when not in use. Shouldn't have to turn everything off in order to get good battery. I've tried using 60hz but it's too laggy and jerky so I'm sticking to adaptive.

Someone on reddit was saying the same. I replied back with my amazement of 6 hours and 24 mins sot with 49% left. But since the April update never had that battery since. I get just over 6 hours sot. I posted on here as I think that was the best sot I've ever had on a phone. Not doing anything different from first getting the phone.

I'll post a screenshot of my screen time at the end of the day. I highly doubt it'll be anymore than 5 or 6. It's really poor.

Isn't much screen time but a lot of music playback over 3 days. Back when it was good. 6th March. Not sure what software version. But could never get these results with the newer software version.

Almost 4 hours screen on time 😂😂 my brother's 2 year old p30 pro has 18 hours since unplugged and over 4 hours screen time with 48% left. I should've kept mine and waited for a better phone with better battery because I doubt Samsung will fix it.

I know the phone can get amazing battery. It proved that the first 12 days from purchasing. Let's hope they fix it.
