Samsung Galaxy S7 Edge 935F Battery Drain - Samsung Galaxy S7 Edge Questions and Answers

I've got the s7 edge and the android system is draining about 15%,but the screen on time is amazing. About 7 hours when i play games,call people,message people. Is this too high?
Here i have a screen shot of the android system usage. Is this normal? I have all the wireless things off,i only use wifi.

I am also experiencing same issues. SOT is good but when phone should be doing nothing it's draining battery... active display is off. No Facebook.. standard sync with Google... I'm even using grenify..

S5 Battery affected by Gear

Hi All,
Just throwing this one out there but has anybody noticed the battery on their new S5 is not as great as the reviews all believe?
I got mine on Thursday morning in Switzerland. It's the European model - and I brought it home to the UK.
Charged it up fully, then let it discharge which took about 15 hours (though eight of those were in bed). Then yesterday, I charged it from 2% up to 100% at about 1pm. It was down to 20% by 10pm. Obviously, I'm using it a fair bit but no more than the other reviewers seem to imply.
I have it linked to my Gear 2 Neo and wonder if that's the cause. But I can't see how it would be as GSAM reckons Bluetooth is low usage and also my friend is using his connected to the Gear 2 and tells me yesterday, he had 90 mins of Netflix, Facebook and general playing before he got down to 90%. GSAM tells me that the kernel is the biggest user.
I vaguely seem to remember the S3 having a similar battery drain at first and not being sure what it was and it settled down eventually - but I'd be interested to hear your thoughts and experiences. By the way, I have Power Saving ON here too!
As a guide, it is now down to 93% after about an hour off charge with the screen having barely been on.

It's kind of common sense to expect degraded battery life due to an always connected device like the Gear.

I thought that initially but the gear is using low level blue tooth and even GSAM says it is barely responsible

Something might be up with your phone. I have the US AT&T version of the S5 and my Gear 2 Neo is constantly connected and set to sync every 3 hours.
After 3 hours off the charger I'm down to 94% battery. If anything the battery on my Neo is what I'm concerned about. That's at 83% at about 8 hours.
That's what I'm concerned about.. as a routine, I installed a load of my most commonly used apps straight out of the box, but they're not running and not huge battery drainers.

Battery is at 90% right now. saproviders which has the same icon as the gear settings app (so I'm assuming this is the service) has used 4% according to battery stats. Screen time is at 30% for me. My gear has used as much of my battery as being on wifi and cell standby.
It definitely appears to be my kernel that's doing it - but what? And how can I stop? See attached screenshots I just took.. Hope someone can help
After a new install always andoid is doing something intense ( my guess is that is scanning your phone). I installed cpu spy from gplay and I checked regularly for the deep sleep time. If you have zero time in deep sleep you have to turn off your phone and then back on. Check again deep sleep state.
P.S. Real life battery depends mostly on screen on time and the quality of network signal in your area.

Hi Calinormy.
Thanks for the response. So, I just installed cpu spy and it tells me that my phone spent a flips chunk of last night in deep sleep. I am flummoxed as to what this kernel usage is.
My instinct would say the constant connection to the Gear Neo watch but I know people also using that watch who say that it is having no impact on battery life and in the gsam stats, it seems to reflect that.
I wonder if the kernel usage will calm down after a few days.
Boooooo

I have a S5 from AT&T and it is connected to my Gear Fit. My Gear fit is the top battery user at 19% followed by Android System at 16% and Screen at 14%. Everything else is under 10% including Android OS. I would find my battery down 8-10 within 1-2 hours but I would listen to music via Bluetooth in the car ride to work which is 45 minutes. It has been 8hrs and 45minutes since my phone was at 100%. I am now at 58%, so about 5+% an hour drop. Now my usage is email, web browsing, light facebook, LinkedIn. No heavy video and have Wifi turned off but bluetooth is on for the Gear Fit.
Also, it took two hours of charge time to go from 10% to 37% charge last night which seems rather slow. I was plugged into a USB 3.0 slot on my PC. My iPhone 5 would have been at or close to 100%.Hoepfully it gets faster over time.

Gear S and Galaxy 5S battery drain
I forgot and left the GPS on (gear S). My Galaxy S5's battery started draining at an unbelievable rate. Turned of the watches GPS and all was fine. Seems as though if GPS is on, it's always communicating with S Health even though I don't use it.

Galaxy s5 battery drain 50% in 3.5 hrs + overheating

Hi,
I bought my galaxy s5 exynos version. It is overheating a lot. Its body gets pretty hot and temp sensors show that the battery temp is 38 degrees and body temp is 33 degrees. The battery life also is really poor.. it went to 47% in just 3.5 hrs of usage even with power savings. Is it a problem with phone's battery? I have attached a screenshot of battery stats.
Are the other users using smg900h facing this problem of heating and battery drain? is there any workaround? Please help me.

Not at all... There's something wrong with yours. I usually get 6+ hrs screen on time on mine.
Battery lasts a day.
Any app you recently installed? Or maybe your SD Card has some corrupted files and the Media Scanner gets stuck?

No the media server isnt popping up. Now as I am writing this , the battery drain slowed down and now it is on 23%. This is my first discharge of phone though.. Also what about overheating? Mine remains warm while browsing and becomes hot after using a bit of camera. I dont know why but my ears feel the heat during a voice call.

Hi! sorry about my English.
I'm having the same problem with my exynos galaxy s5. It sometimes gets really hot and the battery drains really fast, even with low usage (emails and whatapp). It's definitely a software problem, because it disappears on reboot. But after a while it returns.
After a reboot i can get sometimes 4.5h to 5h or more of screen on time with no overheating, full day, but than something triggers and i have 2.5 screen or 3h max on with a hot device on wifi, and terrible standby time.
I can't pinpoint the problem. It's not a wakelock problem. I Checked wakelock detector (PC version, since my device is unrooted), and it shows only 8% wake on a full day (yesterday).
The battery on setting shows normal usage: the screen is always on top, followed by android os.
I really don't know what to do, besides keeping rebooting the device every day. No luck turning locations services off.
As I mentioned, that is not normal at all, this is my battery life:

Do you have the Exynos or the Snapdragon version?
i'm having similar issues with mine, but i managed to get better battery life by turning off location reporting, samsung account,chatON, my magazine, polaris and changing the location to GPS only, it's not drastically different but as of right now im at 61% with 13h off the charger and 30m on screen time.

Yes, an old class 10 16GB card. I have it since I got the S3... I stopped using it while I had the Nexus 4 and 5.

Dont have this issue at all, i charge it when the battery is below 20%
use greenify and blaze kernel for SM-G900F with the power suspend 1% drop in 5 hours
Try to reboot every time of overheating. This should resolve the problem.

man! Really ?? I can only get around 3 hours and 40 minutes at best.
which variant you're using bro ? I am using SM-G900H and trying to buy another spare battery.
Do you perhaps have 1+ Exchange accounts filled with data (email, calendar, contacts, memos, ..). I had this issue on my Nexus 4. As I wiped and flashed the device often, I noticed that the issue was not appearing when I forgot to add one of my Exchange accounts. What fixed it was deleting most unwanted data from my Exchange accounts (old e-mails, all sent e-mails, ecc.). Just guessing.

Yes, the S6 Edge+ battery definitely drains fast in standby. I have the VZW variant. With my previous phones (Note 2, 3 and 4), the battery would drain about 1% per hour during standby while I was sleeping (w/ Wi-Fi on). My S6 Edge+ seems to drain at a rate of 5% per hour with Wi-Fi on. With Wi-Fi off, then the rate drops to 2%-3% per hour.
I'm amazed/jealous at my wife's iPhone 6 Plus. It literally has no standby battery drain. Go to sleep at 11pm and wake up at 6am...battery still at 100%.
I'm getting about 3.5 - 4 hours of SOT. Overall, my battery life is slightly worse compared to my Note 4. But I still really like the phone.
Not at All..
I also Owned this beautiful device..
5d+ standby and 1 hour Sot and 37% remaining
Not bad near me..

Hey. I recomend u arter97 kernel. It saves battery in deep sleep(7 hours screen off and drained %4 only). I think its better than stock kernel's..
I have battery drain only 5% with wi-fi off. If wi-fi is on than 20% drainage.

It's strange. With my Note 2-4, I had less battery battery drain with wi-fi on.
My egde+ runs about 1% each hour in standby with wifi on.
My phone is just out of the box no other apps installed.
I had the same problem, I installed JuiceDefender, it reduces the battery drainage.
I'm getting no drainage during sleep mode

S7 battery life vs S7 Edge

So originally i had the S7, unfortunately it got stolen. So I purchase the S7 Edge, but when I had the S7 my battery life was awesome. I went about 2 days and the battery would still have like 20% left. Now with the S7 Edge I'm losing battery so fast it's ridiculous. You would think with a bigger battery it would last longer. Anyone else having poor battery life also?
Both my S7 and S7 Edge had the exact same apps and I used it the exact same
When I first had the S7 Edge I would easily get 5 hours + of screen on time. Now I'm getting just under 4 hours.
Hopefully a software update will fix it.

That is absolutely horrible...I'll tell ya one thing...you just said you downloaded everything on it? All your accounts and apps and crap right? Well your phone is going to do that. Give it a couple days and see how it goes. You must have some Rouge apps running in the background...download shutapp and your golden. Just remember your phone will die with heavy to moderate use. I Mean you can't prevent it from dying lol. I used to have bad battery life. Now I'm good. I watch what I install closely though. I check there permissions. If you have a smart watch a lot of apps tend to run in the background. With shutapp you identify them and decide if you really need them.

Galaxy S5 G900T Battery drain when screen is on.

I have received a Galaxy S5, the G900T version - T-Mobile USA.
At first I thought the battery was gone.
After 7 hours (overnight) it didn't lose even 1 percent. Standby time is great. There are no issues.
But when the screen is on, the battery drains very fast. I get max. 3h 45. minutes of SOT.
I also have a G900F and I manage to get 6 or 7 hours of SOT, using the same apps, in the same manner.
Any thoughts?
Switch batteries between the two S5's and see if the G900F still has the same good battery life
Switched the batteries. It's the same result. The European version gets great screen on time. The American one drains like crazy when the screen is on.
The G900t (American) is rooted and debloated. So that's funny.
What's also curious is that the standby time on G900T is great.
I have never seen anything like this - great standby and drainage only when the screen is on.

Yeap. It's the first thing I did. Anyway, the phone is for my son.
The standby is great, so he'll have to charge it more often. Almost 4h of SOT isn't all that bad.
Thanks.
Well you've got youtube set as the top battery draining app, so yea playing youtube is going to reduce SoT considerably, video and games will eat the battery
Works fine on the European version using youtube. I get at least 1h and 15 min vs 45.

I have G900T and its battery drain pattern is similar.
