I'm at like 70% battery and 25% of what's gone after 6 hours is the display, having only been on for 25 minutes total? One fifteenth of the uptime accounts for 25% of the battery loss. That makes no sense...
Is there a good way to reduce battery usage by the display? I'm running at what looks to be about 10-15% brightness, not automatic...

You're on target to get an hour of screen on time, but 24 hours total charge time. You just need to use your phone more It's probably not deep sleeping properly. Try signing out of Latitude and anything else that will wake your phone randomly... email, or facebook updating, etc. Disable background data, maybe root and setcpu and underclock/ undervolt
I came to this phone from an Epic 4g thouch, and the battery life is literally half of the 4G tocuh... kinda sucks. I blame LTE.

I'm not complaining about the battery life as a whole. That's not too bad at all, I'm more confused as to how that much screen time really constitutes the majority of my battery use after 6 hours...

Im in just about the same boat actually, 78% remaining, 36 min screen on time which is 78% of my battery use. 5 hr 9 min

Well thats actually a good thing. The more screen time takes of battery, that means everything else is using less. On the 4g touch some people have 30-40% android system useage and their phone is getting like 7 hours out of a whole charge. You want display high, because when it's on, everyhting is working. Everything else should be sleeping when the screen is off.

did you bump charge? I go down to 99 within a minute and 97 after usually 30 minutes with light usage after charging overnight. Of course the chargers don't keep the battery at 100% because that would damage the battery

I don't overnight charge...Once my phone hits 100 I unplug it and I'm down to 99 very soon after and down to 90 pretty soon as well

Right now I'm at 88% after ~4.5hrs unplugged, including about 30 minutes of streaming Top Gear over wifi.
I'm pleasantly surprised.

I'm having mixed results with battery life. Really good standby time at home, but not so great at work. I work in a low signal building. 1 bar LTE and 2 Bar 3G, but the 3G's data doesn't seem to work on any of my phones. I lose about 40% in the 6 hours that I am there. I guess the aluminum isn't so great in low signal situations?

i'm currently getting 2-3 hours of SOT. not very good. right now i'm at 1h and 55min with 35% battery left. i took it off the charger at 9am and it's 4:15pm now. going to have to charge again before bed tonight. cant wait to get that extra battery. so far this battery life has been bad.
part of me wonders if LG knew this so that's why they are offering an extra battery promotion.

First cycle. I have been having mixed usage. Auto brightness LTE only. I'm at 5 hrs 25 SOT. I'm pretty happy with battery life. Phone is great so far. Way better than my old G4.
Once I get my second battery it will be more than adequate for my needs. I travel a lot for work so I'll report back how the phone does while in the air.

Day 4
This is day 4 with my g5. Everything is running fine except for my battery life. Here's some screen shots of what mine is doing. As you see I don't have a lot of time with total battery usage before I have to charge it again. Screen is the top usage but my battery life is poor. I don't know how to fix it. I could disable a ton of services but then what would be the use of me having this phone if I have to cripple it? It's sad.

My first day of use. Everything syncing OK Google always on is off and so is ambient display.

Those are really bad stats. Were you doing something battery intensive like GPS navigation or gaming?

I wish. Then I would have a reason for the bad battery life. The only intensive thing that I have been doing is Snapchat and Facebook and YouTube videos and ESPN videos.

First weekend, Bluetooth on all day connected to me zenwatch 2.

So I'm not the only one with really high "phone idle". Haven't been able to track that one down. I even disabled the Always-On screen just in case it was related.
I also get significant (like half the battery in 7hrs) drain from Google Maps. I left my phone unplugged over night and it ate through the battery at some point. Second time it's popped up.

S6 Battery - Accubattery - How is this even possible???

Okay so I have this phone for over 3 years now as my daily phone and the battery started deteriorating fast, up to where I will only get between 1h - 2h SOT (phone was always on stock firmware and not rooted).
So yesterday I flashed Noble Nougat Rom 5.1 with Kiboi kernel.
This morning I installed all apps again and after the battery died, I plugged it in with Accubattery running.
As I write this, Accubattery says 2724mah has been charged in 1h50min and it is 90% charged. Will post a screenshot of fully charged stats.
Battery design capacity is only 2550mah. Is it possible that Samsung limits the phone not to use full capacity of battery and Kibio kernel "opens up" the bottleneck? Are the stats wrong? Does Kiboi kernel mess up charging current recognised by Accubattery? Whatever is happening is beyond my understanding and reasoning.
I ordered a S7 batter to replace the "bad" stock battery, but now the stock battery looks not so bad after all. The proof is in the pudding, however. Will see how this charge holds up and let you know.

Screenshots
Had to unplug phone at 94% to take a call. Screenshots below.

Could be a bug.
Or maybe someone put an S7 Edge battery in your phone before you got it.

Between those 2 options, I'd say it is a bug, because I bought this phone new, unless Samsung put it in there for me.

Okay so I resolved that it is some kind of bug causing Accubattery not to be accurate. After 18h light use I only managed to get 2h30 SOT of this charge. Battery still sucks so now waiting for S7 battery to arrive.

2nd Charge did much better, 3h45 SOT. It felt like the battery will never die (i want to have 2 - 3 full charge/discharge cycles with new rom and kernel).
I think the new rom and kernel is a good match for the battery because I notice a significant change. Usually the battery dropped about 3 - 5% and hour while in standby, now the drop is down to about 1% per hour.
For all of you struggling with poor battery life, I suggest to flash Noble Nougat Experience 5.1 with Kiboi kernel.

Question Battery Life

I am interested in this battery performance? What SOT are you getting? What do you get for battery time the medium power saver mode?
Any screen shots are appreciated.

It's on Friday and I feel like the first 48 hours it was draining pretty quick. I upgraded from the OnePlus 6t and I certainly feel the slower charge.
Waiting for it to fully discharge and then I'm going to give it a full charge and then I will post my battery stats after seeing how long it lasts.

Full charge before bed last night .. and I drove around a bit today with it plugged in for about 30 minutes. Going to bed now at around 50%. Not going to charge until tomorrow.

I am still trying to figure out if I have a battery drain issue. I am getting the same usage as what I did as my A70. After full charge it says it will last around 22 hours. Usage is the same as with my A70, not sure if that is right.

Standby uses about 1% for every two hours for me with Always On Display. That is always my benchmark even for my last Samsung. There's something using battery wildly if it goes too high after some many hours or even within one hour.
A hint there, try rebooting 3 times in an hour or so. My last Samsung had an issue where normally one reboot would fix the battery drain but it would every now and then require two more to fix the drain.
The battery use stats might help you narrow down to something but if not then you have to factory reset or disable or remove stuff. If its with the rom then it gets more difficult.
If you are seeing the 1% standby for even an hour or two then it should be fine there and the drain is only while the screen is on.
You might also be able to spot certain things the the logcat.

Thank you for your reply. I will try to reboot it. I have done a factory reset but it hasn't helped. I will test it for a few days.

I have 9hours Screen On Time on a pixel experience rom.
AOSP does wonders to this device.

You never know. Funny how much reboots fix things that shouldn't need fixing in the first place
