Help Battery Consumption

[chanchan05]

Ok so did my test again to show you my results.

Phone: Galaxy S7 Edge, Dual SIM version with Exynos.
Fully charged phone, location, background data, WiFi and data turned on. Sync turned on but managed via Green Power.
Screen brightness at 50% on auto.
Read an ebook for 19min (the chapter was engrossing, lol. Finished it before I realized I took more than 15min)

Results:

The only difference I can see is that I'm using Bookari instead of Moon. I doubt GreenPower has anything to do with it. It's just running to manage autosync and wifi connection.

My phone is not hot at all. Hardly any change in temp. So the question probably would be how is the ambient temp in your place (I'm in an airconditioned room), and maybe you can test using a similar app set as to what I have.

Are you sure that you have the Exynos version? The SnapDragon version (USA and Canada models) is less efficient in battery consumption, plus the last update (April) had a battery consumption bug, where it's using up battery more. The update next month would ideally fix it. On GSMArena battery endurance test, the Exynos was rated to last 98h, while the Snapdragon at just 87h. This was before the battery bug.

I like your 3% in 19 mins, my present 5% in 15 mins and extremely warm device after use is a concern. I don't believe MoonPro is the cause of the issue, if I use any other app such as Reuters, CBC , VOA, etc, the battery consumption would still be 5% in 15 mins. Besides if I were to use MoonPro on my Moto G 3 gen phone, the battery usage is 2% in 15 mins. And I was doing 2% in 15 mins on the Samsung S5 previously. I have less than 10 user installed apps and I install only "main stream" apps and no games.

I'm certain my device has the Exynos CPU. It is a G935W8 model. There has been one software update so far. Ever since this software update, I noticed the excessive battery usage and warm device after using the phone. I remember it clearly because after I finished using the phone, the phone felt like a hot water bottle in my pocket.

I hope it is this last software update that is causing the issue. If it is, I hope it gets resolved in the next software update. If this does not gets resolved, it is silly, considering the Samsung Galaxy S7 Edge is a top of the line phone with a 3600 mAh battery and it performed worst than the Moto G 3rd gen which has a 2470 mAh battery and costs a fraction of the S7 Edge.

Hate to sound so simple minded but did you try installing battery doctor. apk it has many features to help reducebattery consumption,or clean master,that has a feature that stop apps from auto starting and close consistent running background apps,yes keep brightness to a minimal,but also always make sure you close all apps when not in use,plus are you using the charger that came with your S7,I do beleive it runs on a little more power than previous Galaxy's so your S7 might not be getting the right amount of charge it needs for the battery to run at it's fullest.
Good health & good luck.

Not true. That's the worst thing you can do to a phone. Not only does clean master steal your data and sell it (they unabashedly admitted that's how they earn), it goes agajnst Android algorithm. Eventually your phone will slow down abd eat battery faster and become totally reliant on CM to even work where you can even text properly unless you run CM. Read this:

Not to sound so negative,I love working on and with mobile devices enough to not let myself succumb to fear over something as simple as a cleaning apk.
But I do appreciate the thought and consideration enough to warn me of it's harmful dangers it has,thank you.

Maybe you should be afraid....be very afraid!!!

http://adexchanger.com/mobile/cheetah-mobile-hunts-its-next-prey-mobile-monetization/
Known more as an app publisher than an ad tech player, the Beijing-based mobile media company launched its own global ad platform on Monday.

It’s part of Cheetah’s grand plan to become “one of the top five mobile ad vendors in the world,” said Cheetah Mobile CTO and co-founder Xu Ming.

If you ask Cheetah CMO Xinhua Liu what Cheetah is, Liu – who quips that the “M” in his CMO title also stands for “monetization” – will say, “We are a data company.”

And that’s because the Cheetah gathers quite a lot of data on its users, everything from device ID, language, how often an app is being used, at what time of day it’s being used and when an app is uninstalled.

Sure the idea is to get their "FREE" Clean Master and Battery Dcotor spyare adware trojans on as many devices and users as possible. See also, Qihoo 360, DU(Baidu), BOAT, GO, Dolphin, etc.

For Google, Faceebook, etc, the United States has strict data protection and privacy laws, the People's Republic of China may not have. OK? I'm in China myself, and tend to be very careful about what I use.

I'm sorry but you are so sadly misinformed. What I said has nothing to do with money rather that Battery Doctor and CM cleaner breaks your phone. It doesn't make it faster. Those apps slow down the phone more and more over time.

As for you losing money, it was a mistake on your part and nothing to do with Google or Facebook. I have had both on my Android phones for the last 6 years and nothing of the sort happened. From what I understand you bought something off a Facebook game and got embezzled? That's not Facebook's fault per se either. The games on Facebook are separate companies from Facebook, they are just front ending Facebook for their publication. Hence, you are mistaken in blaming either. It's a common occurrence actually, people blaming Google or Facebook or Apple or whatever when it is an app at fault, or maybe manufacturer. So it's not surprising yoy might be blaming them. But this is another matter entirely.

Clean Master may be selling your details to hackers and you don't know it. You're givinh it access to your pictures, bank app data, phone logs, etc, and they're selling it.

On battery doctor, that RAM freeing process is actually harmful to Android. You are sadly misinformed on the capabilities of technology if you think that Android's built in security is able to prevent damage done.

I have to agree with the above, I don't believe in installing any kind of battery apps because those battery apps take up my phone's memory, use my data for ads and drains my battery as well. The other important reason is a spyware or malware, if any, from those battery apps. Matter of fact, I have uninstalled GSam Battery Monitor after using it, I don't need GSam Battery Monitor sitting around in my phone taking up my memory, data and battery juice. If I need another set of battery statistics, I can simply reinstall it and uninstall after using it.

As GSam Battery Monitor indicated, the screen uses 91% of my battery in that 15 mins. I do believe the UHD screen is the issue, I am hoping the next software update will resolve the issue.

Would be nice if you could write in paragraphs. I skimmed through some parts of your post because of that. You have a good suggestion, backup and factory reset. I'm going to try that when I have time or wait for a software update (I have one software update previously that addresses screen sensitivity, I'm suspecting that previous software update could be causing the screen to consume the battery excessively)

Would be nice if your could write more coherently. Your case would only happen to Developers, as Google Apps are advertised on Facebook, and on some apps Facebook is used as an individual notifier. Mobile advertising IDs are used to create customer lists for you to be able to create targeted ads. Would seem actually that you enabled something during your implementation of your app or on your registration to Google as a developer if they were asking for an advertising ID. That's something that's not accessible to a normal person. Heck you can find out about mobile advertising IDs on Facebook help pages. Ignorance really isn't bliss, you make mistakes because of it. Look at that case you mentioned, it's a prime example. You had no idea about the mobile advertising IDs.

Your being a developer has nothing to help your suggestion to make it more believable when you apparently know so little of how Android works in the background to even suggest using a task killer. We are attacking your suggestion of using Cheetah Mobile products for three things: 1 it doesn't help, 2 it actually worsens things, and 3 it actually steals your data.

 

[ThePhizzle]

Hmmm...good point,could be; only one matter,everyone who logs into google and Facebook automatically gets assigned a Advertisement id,you just don't realize it till it's to late,As well this all happened before I was certified by Google and they didn't take money out my bank account I used my wife credit card to make the transaction and from me they tracked it to my wife card and was charging her for advertisement Id and that's enough to make anybody a little upset, but we're trailing off topic,what has happened,happened,it's just 2 cent woth of advice take it how you like,just my fair warning, not even have to be acknowledged, I just want to know one thing is the cord the original usb charger for the SG7?

I may have discovered the reason for the excessive battery usage. This may have to do with the screen which was set to 45% with auto turned on.

What I discovered is that when using the phone outdoors, the phone will automatically adjust the screen brightness from 45% to the maximum. With the screen brightness adjusted to the maximum, my battery drains fast.

If I unchecked auto, then the screen will be too dim/dark to read outdoors at 45% which was more than bright enough indoors.

This auto-adjustment to maximum occurs only outdoors. If I use the phone indoors, even with bight lighting, the phone stays at 45% with auto turned on.

Anyone else have the screen auto-adjusting to the maximum when using the phone outdoors?

 

[pentel]

Ps.
1. 45% with auto turned on should be the right brightness
2. Auto-adjusting is fine - that's the purpose of the auto feature, but it auto-adjust to the maximum and not somewhere in between.

 

[chanchan05]

You can adjust how much brighter it should be outdoors using the slider.

 

[pentel]

You can adjust how much brighter it should be outdoors using the slider.

1. Anything under maximum is too dim/dark to use outdoors
2. It would be utterly silly if I have to adjust the slider manually each time I'm using the phone outdoor. This is a premium device at a premium price and users should not have to do that.

The issue is the screen is too dim/dark to use outdoors without going to the maximum.

If no one else is having this issue, then the problem is with my particular device.

 

[chanchan05]

1. Depends on your eyes I guess. I live in a tropical country with really bright and hot summers and the brightness at 80% if fine for me.

2. No you don't adjust it every time. You adjust how much you want it to adjust for a particular setting. The sensor remembers your setting. For example, the default is 100% in noon time brightness (lets set that at 100 sunlight). If you adjust that on the slider at 80% at 100 sunlight, the next time you go into 100 sunlight from a darker place, it will only go up to 80% brightness and not maximum. Same goes if you feel it's too dim in a dark room and such.

And I don't think your issue stems from that unless you are outdoors under bright sunlight everytime you use the phone which essentially means it's always on max brightness.

1. My eyes are fine, the problem is with the S7E device, not with me or my previous device. To recap, the problem is the screen is dim/dark if the brightness is not set at maximum, ie. anything under 100%, outdoors. And that is exactly the reason why the phone set itself to maximum when "auto" is checked. Indoors, 45% or even 35% is bright enough and the phone do not set itself to the maximum or deviate from what I've set.

2. 80% outdoors is dim/dark and besides, setting at 80% consumes too much battery. It appears it needs to be 100% outdoors as that's what the phone set to when it's auto. I set it at 45% with auto. When I'm outdoors, it automatically adjusted itself to 100%.

By the way, it's mostly cloudy today, there were not much sun. The auto-adjust to 100% is not dependent on the sun but outdoors under the sky.

Well you could have it checked or just get a new phone if you really feel your phone is faulty.

So far my phone follows all of the manually set brightness adjustments I made. And yes auto adjust is dependent on the sun, or brightness per se.Auto adjust uses the ambient light sensor to detect how bright it's supposed to set the screen. So if it's an overly bright noon time, it should shoot up to overdrive mode brightness. But on a regular morning or afternoon, or a cloudy day it should be dimmer than that. I've experienced my screen to be dimmer outdoors on a cloudy day that indoors under a fluorescent light. At least that's how it's supposed to work.

At this point, it seems we've established that this may be something we can't fix by simple troubleshooting. This may either stem from something faulty in the screen software, or the screen hardware itself. The first one could be fixed by a hard reset. If your hardware has a problem, that's another matter.

I am/was trying to determine if the problem is with my device alone, in which case I will return the phone to Samsung. So far no one seems to have this problem. Yes, the factory reset is an option for investigation and also possibly a future software update from Samsung. I will try factory reset when I find time and can afford to go without a phone line during the reset.

After re-reading this thread I'd recommend you should just return your current phone and get something else. You've spent several days fixated on an esoteric battery life issue and for your own peace of mind it can't be worth the aggravation. It's just a smartphone, don't let it own you.

 

[ThePhizzle]

Nonsense I sometimes have to turn the screen full brightness when outside on a sunny day and your right a lot has to do with auto brightness,due to some devices dim the screen when its in bright room to conserve battery,no different when going outside it dims the screen to sve battery consumption but mkes it very difficult to see,and myabe C.C.05 it's not about where you live but maybe you disbled your auto brightness on your device.
If not did you try taking the plastic screen protector off,if you have not already?
