I just got the phone yesterday and set it up and fell asleep while it charged to 100. I woke up at some time didnt check the time and unplugged it and when i went to work at 8:20 it was at 97% im home at 5 and it was at 53%. I didnt play any games. i just listened to music for around 30 minutes and did a little twitter. Now im wondering if i just need to let it completely die once to calibrate. but if so should i charge back up to 100? im also on ADP3
[Samsung Galaxy S7 Edge Questions and Answers] hp79:
No, don't do unnecessary full discharge. That sounds exactly like my verizon model.

If you have the snapdragon U.S. carrier version, you just need to disable 100 junk packages using Package Disabler Pro, and also get latest updates or wait for it if you're on verizon. Then it can last 48 hours with sparse use.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
You need to give it a couple days / week before stressing about anything. Not enough data to go on otherwise, IMO.
[Samsung Galaxy S7 Edge Questions and Answers] orlans21:
sorry forgot to say which model. its exynos in canada on rogers.

Should i let it go down to 1% and charge before it would turn off? ive heard its best to keep it around 40-80% all the time and not to let it go to 100
[Samsung Galaxy S7 Edge Questions and Answers] hp79:
I think the better thing to do is just use normally while avoiding heat build up while charging. How are you going to manage the charge levels to stay between the sweet spots? I think that's impossible.

If the battery suddenly jumps from say 30% to 5% then you probably have a defective battery. I don't think calibration does any help. If you use a 3rd party app that uses historic data, then it will want you to do the drain and fill for more accurate battery time estimates.
[Samsung Galaxy S7 Edge Questions and Answers] orlans21:
then what should i do?. i do know that versions that end with APD3 have a battery drain issue so hopefully samsung releases an ota fix for this and soon
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
I am on a verizon model with the snap dragon processor. I left for work at about 7:30 this morning and I am just getting off work and I listen to music for about an hour today using my bluetooth headset. Right now my phone is sitting at about 82%. I was also surfing around on xD a, and working around on Facebook.
[Samsung Galaxy S7 Edge Questions and Answers] hp79:
Maybe try out disabling all those crap stuff? That's what I would do if I were you.

Try disabling stuff I have in my screen shot. Who knows, there might be some common battery draining junk.

with this awesome battery and people getting good battery life's im pretty sure the issue is that battery drain bug because really you shouldn't have to be disabling anything
[Samsung Galaxy S7 Edge Questions and Answers] cr0wnest:
I got my S7 edge yesterday and I too am experiencing high idle drain. My Android OS is only 2nd highest among battery usage with screen taking up most of it. However BBS is showing that the phone is constantly awake at screen off. I'm not rooted yet so it's hard to narrow down exactly what is causing the drain but I'm suspecting it's the usual play services wakelocks. :(
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
There's also a lot configured to "do stuff while asleep" by default - AOD - Edge Feed - various diagnostics reportings - etc.

A good first-steps list is in this thread to go through and make choices of what is important to you or not, to keep active.
[Samsung Galaxy S7 Edge Questions and Answers] cr0wnest:
Alright just full charged my device again, and now its deep sleeping like it should (according to BBS at least) and the idle drain is much more managable now. And I did not uninstall any apps either. I will continue to test it and see how it goes. No idea what happened during the whole of today which prevented the phone from sleeping at all.

Each region has some predominant bands for voice/data. A baseband targeted at Mexico may not offer the best radio support for distant regions.

[Samsung Galaxy S7 Edge Questions and Answers] shiner66:
Well can't you keep your baseband while flashing? Isn't it the standard odin package? Sorry I'm at work, didn't have time to dig into.

Inviato dal mio SM-G935F utilizzando Tapatalk
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
I actually think that the drain is caused by the baseband and the baseband is key to solving the problem, because I once kept the APD1 baseband while flashing the older APC8 firmware (by mistake) and the drain was still present. And I wouldn't do a half-assed update anyway. I am still on APC8 so I can wait a few days until the update becomes fully available for my region.
[Samsung Galaxy S7 Edge Questions and Answers] shiner66:
I hope it gets better than that with that update lol.

I'm on APD1 on my Exynos S7 Edge.

I've had battery life that hasn't been as good as the previous firmware.

This stat is from 100% charged. It's looking very good at the minute. I'm happy with it.

Full syncing of lots of apps (including Facebook). Wifi has been enabled all day. I haven't had Location enabled today.

I did a reboot and cleared my cache from Recovery once I reached 100%.

Nothing else has been disabled apart from Smart Stay.

I'm using AOD.

I have 2 questions. First is if I am on Canadian firmware can I flash Mexican one or will it trip Knox. It is an exynos professor in my phone.

Second I had tried a downgrade without factory reset by creating a special home CSC using instructions from XDA. It worked but my end didn't work properly. Was forced to upgrade and all is fine again.

So question is do I downgrade and factory reset or is there a new update coming out soon

[Samsung Galaxy S7 Edge Questions and Answers] h3x3d:
I'm not seeing battery life that's bad enough to consider downgrading. I can easily get through a day of use.

If it's really a problem, consider backing up and downgrading. Otherwise, just enjoy the phone and try not to be obsessed with it.

[Samsung Galaxy S7 Edge Questions and Answers] neezy13:
I've noticed a similar pattern. The last few days had been really bad for me. I left my phone off the charger last night and it dropped over 20% in about 6 hours and shut off. Google play services and Google fit were keeping the phone awake. This morning I disabled Activity Tracking in Fit and so far the battery seems much better. I'm not sure if it is from the reboot or from the change to Fit.

Maybe this will help someone. After the update APD1 my battery ran out way to fast. I tried everything, even factory reset. Today I changed my cell signal (not sure how it's called in english), from 4G to 3G, and it seems to have fix my problem. I just hope it stays that way!

At the end of the day, my battery will last me the whole day and will most likely go over the 7 hr screen on time, but there's something definitely wrong going on here and we're being shortchanged in comparison to our Exynos brothers. It's already been established by more than one tech site that the battery performance of the SD 7 and 7 edge is underwhelming.

The CPU usage coming from Android System and Android OS is astronomical!!!!! ( 1 hr 45 m and 40 minutes respectively)

In six hours of use ( no streaming, no Bluetooth) these are my numbers.

By comparison, on my note 5 after 6 hours of use would average 20 minutes and 8 minutes of CPU usage respectively!!

This is why they're so high and I bet my ass the issue is coming from the kernel so Qualcomm and Samsung better get on this!!

If been using my S7E for about 14 hours now of which if been sleeping 7 hours. Got Always On Display running so no Battery Saving options, Wifi been off during the night as well as Sync. I have the Exynos model. When i went to sleep the battery was at 64% and when i woke up it was at 58%, so it drained 6% over night. Coming from the Galaxy S2 I have no idea if this is good...:confused:

I was also wondering about 2 processes running:

- Mobile Standby [11%, the 3rd proces]

- Device in Standby-Mode [5%, second to last proces]

What is the difference between the 2 and why don't I see them on most screenshots posted in this Thread?

Btw: When i tap on the Android-system proces I get a full list of modules using it, I don't see Doze in that list but everything is translated to Dutch so perhaps i missed it. I mention this because some people think Doze is calculated within the Android-system module, dunno if this info helps even a slight bit but i thought i just mention it.

funny my android system is at 18% according to battery usage

and according to application manager android system has used 9% battery since last fully charge which would be sometime around 7 or 8 pm march 10th last time i charged. it is now 11:30 pm march 11th
[Samsung Galaxy S7 Edge Questions and Answers] mjs2011:
One thing to think about. It could just be an error in the way it's reporting and not actually android system draining. The battery life has been so great for me so far that it doesn't "seem" like there's a problem.
[Samsung Galaxy S7 Edge Questions and Answers] TheWu-Wei:
I found this interesting. This morning my device didn't go into Doze as it usually does, but the graph actually looks better than when it does. I'd still prefer something flatter than this, but it seems to be improving. Really hoping one of the new updates is the silver bullet for us SD owners who are seeing this issue.

Guys I have an Edge Exynos version with the latest GREECE customization firmware and I get terrible battery life. What do you think is the cause of this? Is it the system firmware?
[Samsung Galaxy S7 Edge Questions and Answers] Canadoc:
Canadian Exynos model here.

I went and flashed the original firmware that came with the phone downgrading form the latest update.

Android system initially starts out high but with use drops to 5% or less.

Battery life yesterday was noticeably improved again. Suddenly was on pace for 6 hours SOT with 36 hours Stdby.

WIth newer firmware was barely getting past 4.5 hours SOT with 24 hours stdby. So at least a 33% improvement.

I don't notice any screen sensitivity changes. Can still use an app to access the condensed mode.

So really other than latest security patch I see no reason to be on latest update.

I strongly suggest anyone concerned about battery life roll back to the earlier firmware (Exynos models at least). Then wait it out until a new update fixes the problem.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
Same here. The last "good" Exynos version safe for battery life is APC8.
