So my battery has gone through 6 charge cycles, and I am now getting really good battery life with medium- heavy usage. Very impressed with the phones battery life. Approx 24 hours standby, 4 hours screen on and 30% percent battery still left today. Watched some YouTube, listened to lotsof songs,whatsapp,emails, browser fb etc

Agreed, I am getting similar good battery life as well.
Same here. I'm actually satisfied with the battery!

Check wakelocks. If music is not taking up an hour or so of wakelock, you can still make it better.
So about 12 hours would be considered average/good?

That... means nothing. 12 hours of screen on time is mind-blowing. 8 hours is some extremely optimized usage. 6-7 hours is about what most people should get. 4-5 hours means you have battery life issues. 4 and less means you have severe battery issues.
5 hours and less of screen on time before 1% means you need to diagnose wakelocks and rogue apps.
Ahh, Ok, I was thinking 5 was high.... Thanks for cleaning that up. I'm on the fence about getting this... Doing my homework now... Any complaints?

Have you rooted your phone and do some special optimizations?
Why my screen only on with 20 mins, and consumes about 4.5% power?

Do you mean HTC One? I think my One can last only 5 hours if the screen is on.
How to address the problem? My screen is set at auto brightness, and power save mode is enabled except display option.

Better Battery Stats. Figure out what is holding partial wakelock. Disable anything involving location settings for Google Search and Google Maps/Latitude. If you have MSM_HSIC_HOST wakelock, you have to root and run a wireshark for a long idle period to determine what is killing battery life.

Not really. I will note that MSM_HSIC_HOST wakelocks are seriously the most annoying things ever to figure out. I'm going nuts trying to reduce it, and fixing the issue requires root because you have to install a root application that can sniff network traffic to determine what's causing modem wakelocks.

Yes, the MSM_HSIC_HOST wakelock exists for about 2 hours, and my battery only use 5 hours since last unplugged.
Is it serious problem? I have not unlock and root my phone, is there any other approach to detect that without root?

I was always under the impression that the only time GPS was using the battery was when you could actively see the GPS logo in your notification bar so unless you were always running apps that would use it you didn't need to turn it off?
Usually get 2 days out of mine with a bit to spare..... i'm not too heavy a user in the week though.
Easily get 24 to 36 hours if i'm using it a lot at week.
Really pleased with it.
from 7am to 6pm my battery is left at about 14%. doesnt seem that great. pretty light usage.
only been cycled twice though, so will wait and see.

How are you guys experiencing the battery life? I had 100% at 12 PM now it's 3:23 PM and it's on 64%. I haven't even used the phone that much, 1 hour screen time only. I don't feel like this reflects the size of the battery (3000mah)
I have it on lowest brightness, I always kill the apps right after use and it just keeps draining fast.

I got 3 hours and 46 minutes of SOT from 100 to 0, I had 0% brightness most of the time and only had wifi and 4g on, nothing else. This kind of upsets me, those are not good stats at all...
The battery needs a good few days and a few cycles of discharge and charge for it to become most effective. Wait a week before making any conclusive decisions on battery usage.
Bear in mind this is a large hi-res display, so watch your brightness if you want to save battery.
For me battery life has been great. I easily get a full day out of it with around 3 hours SOT and medium usage.

Wow. I'm pretty jealous of you. When i got my LG G4, on my second day, it only lasted for about 8 hours!!! Even though i had Bluetooth off, data off, 3/4G off, location off, battery saver on and brightness on auto. I am so disappointed with my phone as i am having to charge it in the day and sometimes through the night and i've only had it for a month.
Screen on
Can LG G4 screen on over 4h?
I am having great battery life
Good battery life
Getting through a working day easily. It could even last longer if I was more careful about closing the apps and all those usual battery saving tips. I just leave most of the stuff on... Bluetooth, WiFi, Location... Screen brightness is set on auto and it's plenty bright for my use even outdoors. :good:

While I'm waiting for my verizon s7 edge, I saw a lot of people post screen shot of s7 and s7 edge showing android system use battery over 20%. I just wondering if this is common problem or just happen to several users? This makes me really worry of my upcoming s7 edge.
I have that too. Don't see any issues with it but then again what do I know. Battery is really good still
I feel like it should be excellent.... we always pursue for better right? My nexus 6 is usually less than 5% for android system. Imagine if it's 5% how good the battery life would be.
Yes mine is the same which seems odd to me too. It should be the screen. Like angionicholai said though. Im still getting great battery life. But I would assume knocking down Android system would help a sizeable amount
Yes I certainly am and it's a little concerning but I'm not very worried. Batery life has been quite good and I'm assuming will only get better with OTA updates and our lovely dev's
I feel like every phone has a "catch all" that the basic phone operations fall under, as far as reporting battery drain. I don't think that the battery drain is higher than it should be for my phone, and my android system has shown as high as 36%. Even with that, the phone was still at 62% after moderate use at work all day (10 hours). That's better than any other android phone I've had. My V10 would have been around 20-30% after a day like that.
One thing I have noticed about this phone is that it doesn't sit at 100% for very long at all. Previous phones I've had would sometimes still be at 100% when I got to work in the morning. This phone is at 98% before I get to the car. I think it's all in the way that they report the percentage. This phone appears to be more linear, and other phones try to fake you into thinking the battery is going to last forever by making it stay at 100% for an hour or two.
Try to judge the battery life in a general, overall sense, instead of watching the draw of each application. See if that changes your opinion of the battery life.
Android system is taking up about 30% of my battery use. That's quite high. Strangely, I'm still very happy with my battery life. Probably because I haven't had a phone with a 3600 mAh battery before, and I'm getting 5 hours of SOT out of the box, without any attempt to save power. Plus my last phone was the S6.
Having said that, I might start experimenting with things to see if Android system can be tacked down. The list of processes running for Android system is quite long.
---------- Post added at 06:33 AM ---------- Previous post was at 06:28 AM ----------
I should also mention that this drain doesn't seem to affect Marshmallow's doze feature. The battery graph flat-lines nicely when I'm not using the phone.
Android System is at 31% for me right now. Definitely the highest on any Android phone i've had. I'm just going to chalk it up to the phone settling in. If it is actually an issue, hopefully they'll address it with an update.
Run Ampre, what is the draw on the battery while it's idle?
Android system is 37% while Android OS is 19% and then Screen is 14% with 1 hour on. Phone has been off charger for 3:30 and is down to 83%. However if you factor the use out that would give me 20 hours and 37 min with 5 hours and 50 min of screen time. I just got the phone Tuesday afternoon so I am hopping after a couple more battery cycles this calms down.
Is it possible that everything was more efficient to drop the battery usage except android sysyem. This would result in a higher percentage showing but in turn its using the same amount as other phones. It would helpful to test of someone could post a picture of their android system usage when battery gets low.
Someone should create a Bugs and Issues thread. And maybe down the road add fixes.

I'm on the S5 until my S7 edge comes in. I sometimes get high android system usage when there's background updates going on or after an OTA update for a few days. Usually it seems to resolve by itself. Maybe give it a few days and see if there's still high drain? Also could be a bug that will be worked out in an OTA update.
Mine has the same thing. I disabled everything possible and the idle drain is really bad. My 6P has system drain at 2% so there's clearly an issue here when my S7E has 30-40% system drain

I'm not using my S7E until my screen protector arrives outside of being at home because I managed to get a small scratch on the screen already on day 1. I'll post some screenshots of the usage regardless because it's still high,but for now this is my 6P for reference.

I thought mine was contributed to the fact I use Adguard's VPN connection, so I didn't think much of it especially since I achieved more SOT than my Note 5 did by 1.5 hours. I typically get 5 to 5.5 hours of SOT.

No doubt that battery life on the S7E seems to be very impressive. I'm just wondering if we can squeeze more out of it if we can figure out what's causing Android System to take up so many resources.

guys i played with my new snapdragon s8 last night for like 2-3 hours and set everything up and i love it!
the only worry is so far the battery drain is a little more than i would like compared to my exynose S7 Edge. I have all the same apps and accounts setup now on my s8, and just in the few hours i played with it last night the battery drain was more than the s7e was in the past with that same medium/high brightness and watching a lot of videos and installing apps.
then last night, my new s8 on AIRPLANE mode overnight lost about 10-11% battery life which seems too much on airplane mode, my s7e exynos would loose only a few % overnight on airplane mode.
maybe the phone battery needs to calibrate for a few days? maybe the OS needs to optimize itself more? idk. but right now its morning here and im going to charge it too 100% and see how it fares throughout my work day
When you first get a phone, it'll use a lot more battery until it is fully set up and settled in. I give my new phones at least a week to properly settle before I make any judgement on the battery life.
Remember, you've downloaded, lots of apps, synced accounts and various bits. Give it a few days before you worry about it

Give it a couple days and update us again - you can also use AccuBattery for a more detailed statistic.
~10% overnight with airplane mode is truly a lot. You should be getting about 1% overnight drain after the phone settles.
I get about 3 hours of SOT if i'm lucky on mine. I play a lot of BT Spotify in my truck as i'm in and out of my vehicle all day long. I was hoping for better, I even followed the guide to disable a bunch of the packages etc thinking i'd get more and didnt raise it any.

Idle battery drain is driving me crazy.
I've got three phones here for comparison, the Essential, an original Mi Max, and a Mi Max 2.
The Essential is on the latest 7.1.1 firmware, the Mi Max is on a 7.1 AOSP based ROM (RR), and the Max 2 is on stock MIUI 9 (7.1).
All three phones are running the exact same apps, same apps doze optimized, same features turned on, and everything else exactly the same. Same wifi network, same email polling time, same messages delivered each one, same wifi calling enabled.
Average screen off battery drain:
Essential: 1.4%/hr
Max: 0.3%/hr
Max 2: 0.2%/hr
It's not completely fair to compare per hour drain because the battery size difference. Normalizing the battery size to the Essential phone:
Essential (3040mAh): 1.4%/hr
Max (4850mAh): 0.48%/hr
Max 2 (5300mAh): 0.35%/hr
So the Essential is draining approximately 3x as much battery during idle, and I really am expecting something like 0.5% or less per hour.
What's the key to battery life?
Same problem, came here to see what is up. Looking at the graph, it looks like it took a while for the phone to go into deep sleep, but even using better battery stats, I can't peg down where all the wake time is coming from.
I am on Android 7.1.1 NM181C and have .03 per hour idle drain.

Thank you for your reply
Your comparison of the 2 phones come with 6 series processors which are known to have way better battery life than the 8 series SOCs. You get better performance with the 835 vs the 625 by a long shot but you get battery life.
The battery life on the Essential is fantastic because of stock android and the best for that processor I've seen out there.

I've found something interesting today after reading 100's of post about battery drain. Most of the time my type c to 3.5mm adapter is always connected to my phone at nights.
And I've seen the message 'USB supply power to attached device' Thought that message in status is irritating I ignored it and I found out that is the culprit which doesn't let my phone go to deep sleep.
And I tested this using 'CPU spy'.
Ive been experiencing a battery drain myself. A couple of nights ago i took it off the charger at 100% about 5 hrs later it was at 88% and the phone was sitting idle the entire time and i closed all the apps that were running.
Same problems here with Oreo beta (NMJ32F). This night, I got 20% off during the night (8h) with airplane mode on; you can find battery historian capture attached.
Although the battery historian has overflown, note that BLE scanning is always on during the night and, moreover, I got lots of kernel wakeups (not userspace) due to the following concept:
Ranking Name Duration / Hr Count / Hr Total Duration Total Count
0 Abort:noirq suspend of c171000.uart device failed 46m53s294ms 5066.45 10h57m56.452s 71093
So CPUs are always on... Let's hope for a fix soon!
Best regards,
I'm having the opposite experience. I went to bed last night at 94% and woke up 7 hours later at 93%
I go to sleep and not surprised if I don't lose any percent...
I've been seeing 22% drain over night if I turn my WIFI on
is your essential share diagnostics on?

You serious? Assuming you're sleeping 6 to 8 hours, 6% to 8% is literally 1% drain, and that's great. That's 100 hours of standby, and that is totally acceptable for a high-end phone. The other guy is getting 10% drain an hour, that's a problem. I'm getting a little more than 1% drain on idle, but I charge over night, but I still have between 40% and 60% battery left by the time I go to bed. My OPO would have about the same when it was new with COS 11. By the time it broke (3 years later, and on Lineage 13) I would be 10% if I was being conservative with its use.
