Tried to do a real world test

Mostly used Facebook, downloaded and updated apps over 4G on Playstore, web browsing, YouTube, a few calls, played about 40mins of Games (Hearthstone, Zynga Poker and Slots: Pharaoh's Way) and redid my homescreen theme which took over an hour.

Was outdoors on 4G 60% of the day and at home on WiFi for 40%. Reception at home is terrible, I usually have 1 bar or sometimes 2 or 3 if I'm lucky.

Max Auto brightness set, location off, Bluetooth off, NFC off, no power saving modes, transition animation scale off, 2D GPU rendering

Rooted on a custom kernel (Ktoonsez)

-75mV on all cores

Little core min/max 400Mhz - 1500Mhz

Big core min/max 800Mhz - 2100Mhz

Conservative Governor

Screen off 200Mhz

Thats all I can recall ATM

*edit* forgot to mention my screen is set to AMOLED Cinema

100% to 20%

Hey peeps

I did a test on my device last night which was an overnight test, due to having absolute terrible battery life and the phone draining about 10% p/h whilst idle and on standby! I reset the entire phone and installed nothing but GSAM Monitor.

Everything was off, WiFi, mobile data, everything.

100% at 2am. Down to 24% at 9.30am.

What the actual **** seriously.

Screenshot attatched .

Any ideas I'm completely lost...

Please help!

Wow, not even held awake. I bet your phone is never going to sleep. For a stock phone that unacceptable. I have no Idea how to fix it if you already disabled everything and are on a fresh factory reset. Maybe you need to exchange your phone.
[Galaxy S6 Edge General] skivnit:
How's ur reception.? Maybe ur in a bad area. Do the same thing but with only 3g or 2g enabled. Also check for data usage afterwards

[Galaxy S6 Edge General] bibiner:
Bro. You need to change your device. That is absolutely unacceptable
[Galaxy S6 Edge General] OnlinePez:
Looking at your screenshot, you have bad reception and most likely in the vicinity of a few towers that the phone is trying to ping to.

Like you I also have bad reception at home except I have great battery, so I'm assuming I am located near a single tower so my phone doesn't ping around like yours.

Did you have others phones with bad battery life too? If not maybe something wrong with S6.
[Galaxy S6 Edge General] Crispy92:
It's strange because as I'm writing this to you in my room (where the signal was 1 bar the other night) I'm getting full signal. I'm in the vicinity of two towers one is about 100 yards away so very close. I had a HTC M8 before the S6 Edge and the battery on that was immaculate, usually constant full signal too.

I am getting the phone replaced as the GPS wasn't working whatsoever, now it seems the battery is defective too, just got to wait until Monday for the store to get a stock delivery. I'll try again tonight if the phone has full signal just a straight repeat of the other night.

It's painful when you spend so much on a top end device that this happens, I don't want to go around disabling features left right and center because that defeats the purpose of having a top of the range smartphone doesn't it? I'm ok with mitigating the problem for example disabling WiFi - Location and Syncing but other features nah.

Thanks for the replies.
[Galaxy S6 Edge General] skivnit:
Get it replaced then

My typical usage (plugged in to the old anker 2 amp charger in car journeys.

First day is on a day out at Drayton Manor theme park/Thomas land some photo uploading via 3g 190 photos and about 70 minutes in the car on the way back followed by a day of work including lots of little car journeys

S-heath running as a pedometer

Lots of emails all handled via Gmail

A few more photos for my blog

Some wifi and wireless testing

Wireless calling turned on for when near a known network

Blue tooth and GPS left on.

The only issue I get is forgetting I am on wireless calling and try to drive of and drop the call lol.

Admittedly not had time to check for improvements over the last 3 weeks so probably could be more effective. Also only added Facebook so far not installed my twitter accounts not really missing it either ?
[Galaxy S6 Edge General] bibiner:
Gotta charge phone. No time to drain till 2 percent because I gotta go soon. Tested by playing an 8 hour long video. Do you guys think is good? Brightness on auto BTW. Stock no root. Disable some google apps leaving google plus, youtube, and gmail.
[Galaxy S6 Edge General] tanjiajun_34:
Battery life was really terrible. With my phone like about 60%, I left my phone unattended. Thanks to Google Play services and Facebook, my phone left with 5% after about 4-5 hours. What's with the Google Service/ Google Play Services? I know Facebook has been a battery eater all along but Google? :/ I disabled Location and Google Now already.
[Galaxy S6 Edge General] Crispy92:
Mobile Reception

Well after days of trail and error I figured out that the main source of my battery drain was actually cell reception however I don't understand how the signal can be so bad? Please see the attached photo, I do believe that's a cell tower on the right is it not and I live less than 100 yards from that? it's just strange what things effect reception? Can I change anything on my phone to increase signal strength? Thanks guys
[Galaxy S6 Edge General] Powell730:
Not even 1 hour on screen time and I'm down to 64%... surely this isn't good right? Even with the 11 hours off charger...
[Galaxy S6 Edge General] Poetique:
Hmm...I wonder if the same thing that happens when two wireless signals are too close also applies to smartphones?

What I'm referring to is the fact that, in some cases, if you have say a wirelessly-connected laptop and a wireless router around a foot or less away from each other, the signal can actually be worse than if it were say... 5 feet away. Perhaps you being so close to a tower might actually be somewhat of an issue lol. I can only imagine the kind of EMF a cell tower has to have.

Also, I havn't been following this thread lately so forgive me if you already mentioned it, but have you tried turning off "Enhanced 4G LTE?"
[Galaxy S6 Edge General] Crispy92:
Hey thanks for the reply, I'm in the UK and haven't got that option however have tried to change the network connection settings around and still have minimal bars of signal :(. I do have a laptop relatively close but even when it's off I still have really poor signal, I'm getting the device exchanged tomorrow and will update you on the difference.

It's irritating because I take phone calls from work a lot and all I get it stuttering on the line, temperamental drop outs and usually just plain static. However when I'm at work and phone home (same phone to fiancées iPhone) the line is clear as can be grr hehe :)

[Galaxy S6 Edge General] bibiner:
I actually curious about this point. My area only have 1 bar signal and I lose 1 percent for a night (About 6 hour). For all the people who having bad battery life, most of them are the one with carrier. I'm using F variant. Seems related somehow. Just my observation.

[Galaxy S6 Edge General] varunkumars:
Due to various personal reasons(not because of the phone) I had to change my phone thrice. Now this my 3rd phone. I am on AT&T's version BTW. So in all the 3 phones initially I had the same battery drain issue when on WiFi but no drain with Wifi-off. I tried everything little fix that was suggested in this forums but for a couple of days nothing worked. But on the third day battery starts being stable and continues to be so from there on. So I suggest let it drain and charge it back with a Samsung S6 charger only and keep the charger on even after it is fully charged (during the nights especially). Do this for a few days. I am sure you will be fine eventually. If it works for us should work for you also.

I am really amazed by the battery now. With only 2600 mah it performs better than my LG G2's 3000mah. By no means I am saying this is the best battery ever but it is definitely acceptable. I definitely think battery would improve even more with 5.1.1. Keeping my fingers crossed.

If you want to try the fix you may do that too. Follow these steps. I hope this helps.

Well it's getting worst....by the day.

I'm waiting to exchange it, but stores in orlando sold out, only white 32g .
[Galaxy S6 Edge General] alom5:
My battery is getting stupidly hot now.....lasts the average i expect. ...but the heat is ridiculous. It just stayed happening. ....so don't know what is going on.
[Galaxy S6 Edge General] Crispy92:
Downside to fast charging if that's what you're referring too, also if you're setting the phone up or downloading applications / installing applications it gets quite hot, as long as you don't burn your ear off whilst calling you'll be rite :) I'v only had one point where I'v had to drop my device because it was so hot (onto a soft surface) which was mid-way through fast charging and I pressed the power button (insanely hot).

You can always use a non fast charging method just use a standard cable / charging kit. But unfortunately with the devices design and architecture it will get pretty hot with use, if it's hot whilst idle then you might need to reboot / reset.

I'v just replaced my device today as my old devices GPS died (Honest think the phone overheating contributed to this and somewhat burnt the chip out lol) but I'll post updates on how the new devices battery handles. The idiot in the store restored all my old applications without me asking so straight to a factory reset I go.
[Galaxy S6 Edge General] bibiner:
I'm kinda regret getting this device. But had to stay with it for more than 2 years before I can change. Miss my note 3 haha.

New Device

Well I'v had my new (exchanged) device for around 6 hours now and I'm extremely impressed with the switch. I had a GPS problem alongside a extremely bad battery life % on my previous device forcing me to exchange it for a new one. See attached Image. This is with moderate use, browsing the internet, listening to music for a good 3 hours (bluetooth link to car) and 3 phone calls each lengthy ones. Plus the initial setup including downloading applications and installing the bits and bats.

Usually my previous phone would be down to 20% doing all that and within that time period but my phone is only at 71%! after 5 and a bit hours of moderate use. Steady graph too. I'v also noticed since the swap my cell reception is maxed at full bars and WiFi signal is much stronger too. Keep in mind during the 5 hours I'v had the device on and used it I'v had everything on, location, WiFi, Sync, Viber (background) and took a fair new pictures to make sure the camera was working.

Conclusion? I'm impressed with the switch and I honestly don't have a clue what was wrong with my old device, 1 bar reception constantly and bad WiFi, GPS wasn't working and losing approx 10% per hour whilst idle but this one so far has lost 1% since I put it in idle a few hours ago.
[Galaxy S6 Edge General] Shadyfurball:
Is there No solution to the Google play services and high cell usage? They are always at the top in terms of battery usage. It's driving me crazy!

I'm rooted and tried to greenify/ disable what I can. Google now and location services are both off.

Thanks

Cell standby and freaking Google services murdering me here too.
[Galaxy S6 Edge General] phazey12:
T-mo S6 Edge, My typical battery life for the day now. Almost 13 hours between plugging it in. 3hours+ screen on time with auto-brightness. Over an hour of this was Waze GPS, about an hour of streaming Google Music, few phone calls & texts, android watch connected all day. Had to reboot a few times because my Moto 360 was being dumb which accounted for a 5-10% battery loss. On LTE the whole day as I just got unlimited data plan so stopped turning on wifi.

I do have Google Now cards turned off as I never find them useful. I used Smart Switch to format my phone when I first got it. Pretty impressed with the battery life. I could probably get 2 day battery use no problem if I didn't use Waze to and from work everyday and had my watch connected all the time.

[Galaxy S6 Edge General] fletch33:
unfortunately this was the exact same situation i had when i received a replacement when i cracked my screen and as the days went on i slowly reverted back to the same results my original device was having and now a few weeks later my new one is just like my original.

i hope this is no the case for you but man i was excited when i saw reception and battery being so much better at first. i even had cell standby almost not showing up for a few days.
[Galaxy S6 Edge General] phazey12:
If you are rooted, install App Ops and turn keep awake off for Google play services and Google Apps. it should some the battery drain problem with no adverse side effects
[Galaxy S6 Edge General] Harshaanl:
No matter how many times I fully charge now smart manager only says 10hrs battery life on a full charge. And it's right I only get 10 hours. Before 5.0.2 update I got 15 to 17 hrs.

How bright was your display ? Anything you disabled?
[Galaxy S6 Edge General] ierrors:
Indoor less than a half and outdoor auto brightness. Location and GPS OFF when unneeded and I'm indoor most the time. Disabled unused built in apps. Better to apply dark theme cause the less power Amoled screen consumes on the gray or dark background. GSM mode selected cause I'm on WiFi only.

Ok thanks I'll give it a try.

I noticed however that the startup tab settings don't stick. Every time I open the app again the settings have reset again. Any ideas?
[Galaxy S6 Edge General] phazey12:
Yea, I don't use the startup tab. I just make sure to go into Google Play Services and Google Apps, scroll all the way to the bottom, and make sure Keep Awake is off. That's all you need to do.

Came here to post that my battery life is terrible. I have 50 things disabled I'd say as well. 77% at 10:13am. No calls, some texts and like 10 mins of random stuff.

---------- Post added at 11:10 AM ---------- Previous post was at 10:14 AM ----------

I didn't realize I had GSAM installed..opened it today and saw this. Could the detector in fact be the problem?
[Galaxy S6 Edge General] EVOme:
So after reading this I did three things, charged to 100% and unplugged. My battery sat on 100% for 45 mins.

1. I disabled the Amazon app. The shopping app that I order from. The suite had been disabled.

2. I cleared system cache in recovery. (Not rooted)

3. I turned off location.

At this point, I am not sure which of the three is giving such great results. I bet it's the location.
[Galaxy S6 Edge General] obsydian:
100% morning very limited use as my Gear is used more and still loose 40%, by 10pm down to 40%, my S5 would get serious use and still have 50%.

So overall worse by at least 30% but I love the fast charge, I top up in the morning for 30 to 45 mins and back to 80-90% super convenient and no more leaving my mobile on all night to charge.

Using this as a second phone. Very happy with it so far. This is my best sot. Being a huge htc fan I never thought I would have a Samsung phone. Best screen and camera out hands down.

[Galaxy S6 Edge General] Ahmedivx:
I'm not sure if these figures will serve as a good measure of the battery life, for Me after one month of usage, I can get a total of 5 hours and 50 minutes screen on time, and a total discharge time (from 100% to 5% when i usually start charging the phone) of 1 Day 17 hours provided the following:

- Power Saving is always on

- Screen Brightness is always at 20%, on auto mode outdoors in bright sun.

- Youtube usage is around 1 hour (1080P and 1440P).

- Voice Calls for around 2 hours.

- Always on Wifi (no mobile data at all) and not always connected, basically two locations at home and at work.

- Other activities as they demand (so little gaming by the way some days i don't play at all) Facebook, WhatsApp, Messenger, App downloads and so

- Standby periods in between

I'm not sure if these figures are good or bad and I can describe myself as a medium to light user but comparing my same usage to my former 2800 mAh Galaxy S5 and 2100 mAh Galaxy S5 Mini, I guess it's about the same.
[Galaxy S6 Edge General] Wiidesire:
It's ok, for comparison here is mine on the Edge with ~18 hours WLAN + 3 hours LTE, highest auto brightness + Bluetooth always on and connected to my Gear Fit:
[Galaxy S6 Edge General] Clay330i:
Aren't you defeating the purpose of the upgraded hardware by running in Power Save mode? Seems like you're trading lag for battery life, but I can't blame you with all battery life issues everyone has been having.

And it's odd that only the US phones seem to be having battery life issues.
[Galaxy S6 Edge General] Powell730:
Just to update my previous post (can't edit previous post and add this pic, using XDA app.)... I came home and put on wifi and within minutes started getting android system in my battery stats.

I thought someone said in another thread 5.0.2 is known for this... hopefully a speedy update will fix it.
[Galaxy S6 Edge General] Ahmedivx:
I guess that's good since it can be considered as full load

---------- Post added at 08:32 AM ---------- Previous post was at 08:17 AM ----------

Not at all the upgraded hardware served its purpose for me, I have always been using power saving mode in all my Samsung devices since it has been introduced, but when I compared the raw performance of the devices with for example Antutu, my S5 was scoring around 38000 without the power saving mode on, my S6 Edge scored around 69000 without the power saving mode on, and guess what it scored around 55000 with power saving mode on, I don't think people turn on power saving mode when they are benchmarking their devices but for me I thought of giving it a shot to see how far power saving will affect performance and suprisingly it did very well (from the common figures I saw it has beaten both the Note 4 and the S5 at their peak), but as we all know benchmarking softwares are not a real or practical measure, in my day to day use, I don't face any noticable lags at all.
[Galaxy S6 Edge General] EVOme:
So as I said....something I did took me to a new level...
[Galaxy S6 Edge General] Shadyfurball:
Well I've used this and it doesn't do anything for me in terms of stopping Google play services or cell usage. Still the same problem.

It's doing my head in!
[Galaxy S6 Edge General] bibiner:
Gotta I'm truly disappointed with the battery performance. Oh well, though everything others stuff about this phone is pretty good. Just freaking battery.

Hi,

I cant really tell that much, but before rooting everything was perfect.

I rooted, installed TWRP recovery, the simpli kernel and the deep sleep fix.

Everything is working better than expected. I just did for the use of Backups, root explorer (headphone volume) and lucky patcher.

Not a moment where i had problems.

925f - just a Quick info.

I had no boot loop, but it took time to boot the first time.

Thanks to all the pro's... thank you!!

I think my battery has settle down now.

First day of using, I got freaked out by the battery drain, 10% while screen was off, WTH, now even with Night light on, around 10% for 7 hours, havent tried it with Night light off.

Now I got pretty much averaging 14-15 hours time from full to 5%, 5-5.30 hours SOT.

What I have as of now as much as I can remember :

- Wifi on, Wifi power safe mode on, wifi keep awake during sleep never, wifi always allow scanning off.

- Location on gps/wifi/mobile

- Disabled google play newstand, books, games, movies tv, music, google plus, facebook, milk, skype (I dont use those)

- Power save mode ON at 20%

- VoLTE off

- Google sync only for contacts and gmail

- Screen brightness manual around 25% (this phone is really bright)

- Google play store no auto update

I unplugged my phone in the morning at 7.30AM , I dont play games, at works pretty much just browsing, short phone calls here and there, so when I got home around 6PM, I still have like 50-75% left battery, then when I'm home, that's when I use it a lot, especially for watching movies/dramas, and usually battery died around 10-11 PM. With 5-5.30 hours SOT, this phone actually is better than my Sony Z Ultra, which averaging 4 hours SOT with same uses.
[Galaxy S6 Edge General] Poetique:
For some reason today, looks like I just might crack 6 hours of SoT, even with Cell Standby eating a ton of my battery. I'm at about 4 hours of SoT with 35% battery remaining. Even played a bit of Ingress and a couple other games today.

I did disable a bit of Google's nonsense in the background, but frankly I'm not even sure how much that is to blame. Android System (22%) and Cell Standby (20%) are #1 and #2 for eating my battery.
[Galaxy S6 Edge General] blacknet101:
These are my batter stats for today and i barely passed 50% since disconnecting from charge lol
[Galaxy S6 Edge General] Criticalstriker:
Its just so true about the cell signal. If Im in a shıtty signal area (like 2g or even GPRS) the phone will die in like seconds in front of your eyes. In this scenario I get 2 hours of On Screen Time and its maximum.

However, if you have a stable connection or something like that, 3G all the time or HSPA or whatever, I get to have 4 hours on screen time.

and I own the phone for like a month already. So I think from my observations I can tell that S6 is too aggressive about the "signal search". Its looking too powerful for a signal or I don't know how to put it.

I am thinking that the "patch" update we will get somehow smoothen this aggressive cell search thing.
