Battery hog - VPN - Samsung Galaxy S10+ Questions & Answers

Recently upgraded to S10+ and started using a VPN. I use Nord. I have noticed the app on my phone is a battery hog. I reached out to Nord and they told me that is the way it works and besides they didn't think it causes a big battery drain anyway. Was wondering what other folks are using on their S10+ and how the battery use issue is? I'm still in my 30 day money back guarantee window so I can get a refund if I want.
Thanks.

I use private internet access and have the same issue. I had this issue on my S8+ running Nougat and Oreo too so I don't think it is a Pie or S10 problem. I haven't tried manually configuring the VPN through Android to see how that affects it since it seems to be related to the VPN app.

Ah, was wondering about that. VPNs are new for me. Have no idea how to set up manual configuration. Will see if I can find some info on it. How do you like PIA, battery issues aside? Was one of the VPNs I considered.

I have used both PIA and NordVPN. NordVPN works (currently) with Netflix, while PIA is firewalled off by Netflix.
Regardless of phone used or VPN service, battery consumption has always been noticeably higher when using VPN, this is likely due to the encryption/decryption arithmetic being done on the data in real-time.

I use OpenVPN to tunnel out of my work's network. They block EVERYTHING. I have it running 8-9 hours a day for a week now. No problems with battery that I've seen.
To be fair though, I don't have time to use my phone much at work. 7h 15m today and 0.6%

That's how VPNs work really, 100% of the traffic has to be sent to their servers, it's an expensive operation and drain is to be expected.

PIA has an option where you can exclude apps from the VPN.

Yes! After poor battery life (3-4hrs) I've isolated the issue and LOVE it!

I was getting horrendous battery life on my new Nexus 7 stock and rooted / custom ROM.
I decided to wipe, install zero apps except Chrome and fire away at the battery. YouTube has streamed 3 hours worth of an HD video and I'm at 72%!!! Nice!!!!
I was using FB and FB messenger, Firefox beta and really that's about it. Needless to say I'll hold off on installing them until they've been optimized with 4.3

fwiw - i have chrome, fb and ff beta also installed - no battery issues. I dont use FF messenger though.
Its FB. Seriously. Its a horribly written website with horribly written apps. It sucks information all the time.

I'm sure my battery life would be great with no apps installed too. I'm holding off on wiping mine though, because I'm sure after I root and reinstall my stuff, the battery life will go to crap again.
On my Nexus 7 Google Services has an inordinate amount of keep awake time. So I'm hoping updates will fix the issue.

I've heard people uninstalling Google Services helps. Might cause issues elsewhere though. I think certain battery savers can limit specific apps from keeping the device awake. Im on CM and my device goes into deep sleep quite often. Like 86% of the time.

A thousand times THIS.
If you really want FB install tinfoil. You lose notifications, but it's FBs garbage constant notification polling that is keeping your device awake.
Not trying to defend Facebook but.... Its not like fb doesn't have the option to turn notifications off. Chat availability off. Refresh interval to never. Messenger location off.
At some point no matter how bad the app is it comes down to user error.

It doesn't matter. I turn that crap off and while it probably helps, FB is always eating up tons of memory and keeping the battery drained.
I use APW Widgets, setup a Facebook widget, and click through to the mobile Facebook page using Next Browser. The Facebook app has some perks over this but using this method, I know its not leeching my contacts and mobile usage.

I believe you as I've had issues like this too with many apps.
What I don't understand is how two people with same hardware, same ROM, install same app, one will have drain and the other doesn't. For example I have FB installed on my N7 2013 and its fine (at least it doesn't pop up in the usage chart if I don't use it).

Using memory doesn't = using battery,
With those settings the device should idle perfectly. Assuming the rest of your set up is well behaved of course.
While your device is up and running the process will run time to time but it shouldn't cause any noticeable battery drain.
Don't get me wrong I can go on and on about all the stupid things that app does but set it up that way and you should not suffer any battery issues / drainage.
Once the MBA and CEO Class got their hands on Facebook it was Game Over .....
Most MBA's and CEO's aren't well enough educated to run a technically/scientifically based operation .... Look what happened to Gateway, Yahoo, Dell and almost happened to Apple in the 90's before they brought the Brains back ....
Google is one of the few that haven't went that route which is why they are leading the pack on most things. .... As long as the Brains of Google keep majority share and thus control of Googler I'll stay invested but as soon as the MBA and CEO Class takes ovber (hopefully never) I'll dump all my Google stock just like I did with Yahoo in early 2000 .....
Just look at the Damage the MBA and CEO Class did in the late 90's (The wrongly named Dot Com Bust) and in 2008 ..... Mainly because they are too poorly educated to work the technology and their insane belief in disproven Economic Theories like Supply Side that falls completely to pieces in the Tech World ....

I'm gonna tell you greenify changed my life, my battery life that is. Try it out and you will not be dissapointed.
an app that has not been used in over a day.. after a reboot yesterday should not be in top ten active apps and have near 7000 wakelocks when all notifications in the app are turned off. so yes, Facebook app sucks more than just itself

I haven't had any need yet on my Nexus 7, but I found Gemini App Manager to be a godsend on my Virgin Mobile phone. I can disable all the Intents that apps believe they ought to wake for and just allow them to respond to me actually running them. Much better battery life and more responsive phone without memory cluttered by all the bloatware that believes it needs to run all the time.

Anyone experiencing faster battery drain on 4.4.2?

I updated to 4.4.2 a few days ago and am noticing faster battery drain. Just curious if anyone else noticed this?
Yup. Have tried factory resetting twice. Clearing cache. Disabling nearly everything possible. No avail.
Mine was draining a bit faster than normal after the update. I let it run all the way down, and charged it up, and it has been fine since then.
Hope it works out for you guys.

Camera bug = Battery Drain
Did some looking around, and it appears to be a bug related to the camera (i know, sounds a little odd).
Here's one link of many I've found regarding this issue...Samsung has acknowledged an issue and is working on a fix:
"cultofandroid.com/53672/google-vows-fix-android-4-4-2s-camera-battery-drain-bug"
I am thinking this is more regarding the ASOP camera. We don't have that file or app that they say to look for.

I posted this in the 4.4.2 issues thread, but will post here:
EAS continuously running....I found this out as well after the update. I cant believe its low priority for such a major issue. I switched mine to manual just to be safe. I also found a major battery drain issue when surfing on the internet via LTE service.
Any way, I wanted to see if others could replicate my issue:
-Stock (non-rooted) S4 phone with the recent 4.4.2 update on LTE with 5 bars of service.
-I am using Chrome to surf the internet.
-I have Exchange and Gmail accounts. Gmail is set to PUSH and exchange is set to manual. (My hope is that having Exchange set to manual I avoid the EAS issue described above.)
-Majority of the boatware turned off
Scenario: While using Chrome to surf via LTE service I am literally able to see a 1% decrease in battery ever 2-3 minutes of surfing on the internet. Wifi is better, but still drains faster than 4.3.
Can anyone else try and replicate and respond back? I may have to do a hard reset to see if it will remedy the issue. :-/
Thanks,
Eric

Yes I have had worse battery drain with the KitKat update. Hoping for an AT&T update since we dont have the option to flash roms...
What are you actually seeing for battery consumption?
I have google+ at the top of the list with >30% use. Definitely new after 4.4.2 update.
Seemed to be ok for a day and then popped back up. I'm going to try to see if it's caused by 1st use of the camera.

I'm not using live wallpapers.
Rebooting the phone and avoiding use of the camera did not help.
I uninstalled all google+ updates that that has worked so far, but definitely not a long term solution.
Well I would up flashing the MK2 revert, then changed my mind and re-updated to NB1 (these two processes involved many full-wipes and even flashing a .pit file). Installed all my apps one-by-one. I'm now getting better battery life. Still higher than previous usage by Android System (usually ends up being 14-17%).
NB1 now works pretty damn well for me. Once we get root I will be able to disable some stupid things like the boot sound and charger connection sound, along with a few apps that just don't need to be running like Knox and Security Policy Updates...

Battery Performance - Post Screenshots Here

I came from a Z2 and that battery was really great. Not only was it a good size but Sony did a great job with optimisation.
From my experience so far the AM7 does well With the battery using it in normal battery mode which is recommended for games and movies. I don't want to use any other mode to reduce performance.
Let me know what you think. Overall I am happy with battery life but they could have optimised the phone better I think.
Here is an example of a heavy day use when I had the phone off charge at 10am and used the camera loads plus all the other stuff we all use.

Phone off charge at 0530 this morning and its now 2307 !!!
I changes the battery mode to smart and it made the battery so much better and made NO difference in performance (from what I can notice) with films and camera.

I use 2 emails on gmail. Stock launcher and high auto brightness. The phone gives you notifications what is draining. Post a PIC of battery page like below as that's not right. What model you have ?
thanks. i checked out the app but i cannot suspend my connection when my phone is off as i need to continue to receive message and be alerted anytime. also looking at the features of the app it looks like it is already available in the phone tools of this phone which is why i love it it already shows you a lot of info about apps that are heavy battery users and you can set it in a way where you can have them close and suspended when your phone is off .
What I have done so far is to remove my data manager which is being shown to be extensive battery user and also went back to emui suspending nova launcher (there are users saying its draining their battery) and HD widgets so far my battery lasts longer even with mobile data always on.
shame because i like nova launcher if it turned out to be too much of a battery hogger i may have to ditch it and try apex i can never get used to emui having no app drawer.

Ah this makes lots of sense. I was under the impression the 3gb model was just for the people in China and the 2gb model was for everyone else. I avoided the 3gb model as I was under the impression it would have radios specific for that country. Did your phone come with play store installed already or not ? I maybe totally wrong but this could be why your battery is draining so bad still ?? Let me know as interested.
Could you also download CPU z and take a screen shot of the battery section like I have below. The model I am using only shows 3000mah battery and am wondering if yours shows the same ?

Mine says 3000mAh as well. TL09 model.
it shows the same with me on CPU Z 3000mAh. probably the app is not reading it right. i think i was able to sort it out. took out power hungry apps and suspended apps that i dont need running on the background and i am able to get a day of charge at light to medium usage.
From what i know the gold version is offered outside china although some country doesnt have them. looking at my package the document actually says austrailia.

[Snapdragon batteryguru vs Stamina mode]

Dose anyone use snapdragon batteryguru?
Or stay with default function, namely stamina mode?
Or both together?
I just installed yesterday and it is on the way learning.
So, if some of you have already tried some combination of those, I am appreciate it in giving me feedback.
Also, I will give you feedback after testing.
Best regards,

I have used batteryguru before didn't notice much improvement and from what the app was saying the apps you don't use often it stops them pushing the notifications etc until you load the app however I was still having notifications coming from all the apps on my phone. Your milage may vary though depending on what you use your phone for.

Well, peers have told me:
1. Battery saving apps are pointless with how advance Android is nowadays. Also especially since Sony has already included enough battery saving software in their devices.
2. The battery saving app keeps running, so that itself drains the battery.
What do you think?

1 is correct
2 is partially correct, depends on which power saving app, I didn't notice any real drain from Battery Guru, though it didn't help increase it either.
I've never used Battery Guru before, but I think I'd rather purchase Tasker to do the job of location based Wi-Fi for my phone.
Would it drain battery or such if I have that act like juice defender/battery guru instead?
Sent from my D6708
Ive used battery guru for a while, but looks like it doesnt do much. So i uninstall it already.
With the latest version of Stamina I can't really see what BatteryGuru can do to further improve things.
The Z3 effectively turns just about everything off in standby if you ask it to, firing up when you start using the phone. Battery Guru attempts to learn your usage, so it will still allow data at certain times and restrict completely at others.
I'm very happy with Stamina and uninstalled Battery Guru some time ago. I still have it on some other devices tough, especially anything that doesn't have any native power saving functions.
I do wonder how Sony is going to combine Stamina with the Lollipop battery saver, which is a simple on or off - along with the horrid orange bars. That's very much all or nothing with far less intelligence, so maybe Sony will not use that at all.

Exynos LTE battery performance (Battery Historian)

Aware of the current discussion around the LTE drain issues with the Exynos version of the phone. Yesterday I did a full 24 hours off charge on exclusively mobile data and lost around 65% for 80 minutes SOT.
Before taking it back to Samsung I wanted to confirm that there wasn't anything else causing the drain . I'm no expert with battery historian but I can't highlight the causes beyond the following:
Screen off uptime: 3hrs 27 mins
Kernel Wakelocks: 5hrs 32 mins
CPU Usage: 2:32 of user time vs 5:14 of 'system time'
Kernel Overhead 1:45
"999:MAILBOX_CP2AP" - I suspect this is linked to outlook but can't be sure, causing 150 wakelocks an hour
"Abort:Some devices failed to suspend, or early wake event detected" - No idea what this is
Would anyone be able to provide any more information or assistance in analysing the chart?
Thanks in advance
Try to change outlook. My experience is that outlook was making battery drain crazy, remove it and got other phone.

Have you tried these tests from a fresh install with no other apps installed? Have you tried this in airplane mode also.?
What was the test results using just wifi?

Haven't and wont have an opportunity to do a fresh install for a while, need to do a day on wifi to compare the results.
I did spend a bit of time on wifi and adaptive power saving and it all but wiped out the "999" wakelock (I think this is because the system more aggressively bins the wakelocks "
Will also try safe mode/ removing outlook to see what happens
I'm having the exactly same issue of yours! 999:MAILBOX_CP2AP is appearing crazily! Do you found any solution yet? My phone don't have outlook installed, but the wakelock still going on crazily.. It seems only appearing actively during mobile data is turned on.
My battery has been doing great for me using LTE all day

I'm glad it's not just me! There is nothing on the internet about it either.
Will try staying in safe mode when I have the time

What outlook are you using? Is this the outlook from the play store or is it corporate setup outlook mail using some sort of exchange servers for synching?
I have since my note 9 disabled the stock Samsung email app and use only outlook. Since the stock email app for me was causing drain.

Strange. That's the only app I use for multiple email accounts that seems to be less resource hungry. I still have gmail all though.

I deleted outlook and the wakelock persisted, so it's not that, but I don't have another mail app so very confused.
The 999:mailbox wakelock still appears when on wifi but its negligible compared to when on LTE

Googling that process didnt yield much success.
I use accubattery pro and gsam. I tried to locate and install battery historian but couldn't find it. Maybe its for exynos only that app?

Unfortunately GSam and better battery stats currently don't work on exynos, I have accubattery but it doesn't offer much beyond basic battery stats
Battery historian uses the bug report that you can produce in developer options

Hmm I tried safe mode, even hard reset OS by sending to service center for them to do that for me, still same.
Although my battery life doesn't consider that awful but not satisfying. I started to doubt whether it's some hardware related issue.

And the wakelock persisted throughout? It might be nothing but the only difference I can see between wifi vs LTE
It's so good for battery on wifi but middling when on mobile data

Over a 50% battery usage period I get approx one or so less hours sot using LTE. If that makes sense. View attachment 4768566View attachment 4768567

I'm Exynos, dual SIM, I am an area manager and phone is my main work tool doing audits on them all say. Both Sims work overtime as I'm mobile all day in remote areas, the screen is an auto as I work outside and need full brightness and I use WQHD. Only thing i turn off is aod and I've done the stuff in the battery optimisation thread
I charge in the evening and get 24 hours on the battery , average is 7 hrs sot and 2 hours talk time
This is perfect for me
