VPN on Nougat (Battery drain) - Android Q&A, Help & Troubleshooting

Hey pals,
I don't use Nougat atm but I wonder why the battery drains like hell when I'm connected to any VPN service.
It can't be app related since I tested several apps on two Nougat devices.
Is there anyone who experienced the same?

I do and I want to know if it's normal for a VPN to do this, there are some days where my battery doesn't drain but as far as I know the VPN was on the whole day.

Issues with battery performance

I flashed a rom called nexus experience which appears to be based on cm13 for my kenzo 3gb
Everything works flawlessy but the battery is terrible it barely make half a day with medium usage
I tried greenfy, turned everything to the lowest but no difference
Is that a bug with nexus experience or all cm13 roms are the same.
Can you advise me with the best way to get maximum battery time
Thanks in advance
I have this ROM Nexus Experience 10.4 and battery backup is great and I have tried many ROMs.
I also use amplify module for nlp (allow every 600sec)
I get like 10hours of SOT, but info in battery stats is not showing correct..

[Galaxy A40] Battery discharging quickly with Pie - Solution or donwgrade to Oreo

Good afternoon,
I'm new to this forum and I don't know if I'm posting in the appropriate section. Please, relocate my post if necessary.
I'm quite a newbie regarding phone hacks but I can make my way through the various general processes related to phone updates.
I recently updated my Galaxy A40 to Pie (A405FNXXU2ASJ1, Oct. 2019) [update: after checking on the official Samsung website, I updated the original April version of Pie with the August update and the battery issue started aftewards] and the battery started discharging way faster since then. I'm really not satisfied with this issue and I would like to do something to solve or improve battery life.
I tried Package Disable Pro and disabled a few apps and packages, although I don't really know which services to disable exactly. I also added most apps to the standby app list in the developer options, but it didn't improve the situation as much as I expected. I used to charge my phone every 24 hours or so with Wi-Fi on all the time, no Bluetooth or NFC.
Would anyone have an idea to get a similar battery life (charge once per 24 hours) or explain to me how to restore Oreo (downgrade or flash).
Thank you very much for your help
Weird. My Pixel XL is experiencing slightly better battery performance on Pie. I OTA updated from Oreo.

Well, as regards Galaxy A Series, numerous forums evoke a decrease in the battery performances probably due to some bugs in the update energy management pattern.
The problem is that I had to change the phone to night mode and also charge a black theme in order to slow down the battery leakage while in use.

Idle drain issues on custom ROMs

Hello all,
I tried all the custom ROMs available and they seem to have a high idle drain. I am loosing usually 10-20% per day which is extremely high in my opinion.
The Paranoid Android and Arter97's software collection seems to be slightly better but that is Android Pie based.
Is Android 10 the actual problem for the drain? Do you have any suggestions on how to fix it?
I never tried MIUI so I do not know how is the idle drain on the official OS but I had a Lenovo Tab 4 8" plus before and it was barely loosing 1% per day.
I hope I can find a good setup because at the moment there are not many options for a good 8" tablet. Even the Mediapad M6 8.4" is not produced anymore.
Any feedback is welcome. Thanks!
Edit: I forgot to mention that I use f2fs partitions on data and cache. I am not sure if that could cause any issue but on other devices I never noticed battery drain because of it.

yes. I'm facing same issue too. performance is owesome but idle battery got problem. have been try all android 10 for clover. all of them have the same issue . I don't think android 10 causes the problem because my lavender on miui android 10 battery life very good.
Turning off wifi works for me. When I do not need the device I just turn it off and the battery lasts much longer then when idle. have not really looked into it but I guess it is related to data usage or device not going to "deep" sleep
Yes, I had this issue with many custom roms, except Carbon rom. I've been running Carbon rom since I found this rom didn't have that issue, though it has less features than most of other roms

Yup, I second that. Also using carbon rom and idle drain is good
If you're using magisk then v20.4 have higher battery drain during idle. Try v20.3

Stable ROM for ANE-LX1 to be used as daily driver

How does LiR 18.1 GSI compare to official lineage 16.0? Are there any major bugs in either? How do they compare in regards to battery life and overall performance? How is performance compared to stock EMUI?
I am running LIR 312 as a daily driver. It the first few days the battery usage was enormous, it did not last a full day. That may be because of all the app installations, setting tweaking, downloads, etc. Strange thing was the battery usage was huge even when I did not use the phone. But after a few days everything went back to normal, battery usage is similar than in stock. For my use the performance is similar than in stock. That said that is enough for me.
As for stability and bugs I did not yet find anything that would affect me. After installing NFC patch I have working all of my banking apps. I do not need super-fast charging so I did not test that. The offline charging does not work, but I can not see why would I need that.
While using CAOS11 I noticed that sometimes I lost all phone connections. That did not happen using LIR, but on CAOS it started appearing after several weeks of usage, so I have to wait a little longer to be sure.
As I am not power user, perhaps somebody else could give a more detailed answer...

Question Battery standby drain

Hey guys.
Just for the record I am testing the Xperia 1 iv battery drain in standby.
The phone seems to drain over night by 20% that's alot for juice compared to the Google pixel 6 pro or over phones like the oneplus 10 pro etc.
I have started this discussion to see if anyone else here , having drain issues maybe due to the overheating issue to drain battery down but that's only if the phone is using apps that are demand CPU etc.
I will keep testing this ,my thoughts are, thats alot of battery drain for standby mode.
I think Sony my need to do more future firmware updates to address this issue
mine uses some 5-6 % overnight, generally veeeeery happy with battery life.
Maybe you have something running in the background that is killing it. Something that pings the network all the time. What does batt status tells you?
2nd time charging the device is a little better working out 2 percent per hour at present.
Thanks for the reply

Hi could you please give us your build number ? We have 64.0.A.8.25 in Europe, released the 1st of August, thanks .
in that thread* we 've been said , the 64.0.A.8.25 is only a safety one
* https://forum.xda-developers.com/t/xperia-overheating-problem.4467263/
I am on 64.0.A.5.71 Running a dual SIM mode with a digital SIM. I am also rooted with Magisk 25.2. All my Google apps are removed, so my phone runs without Google support. No Facebook or social media apps, also no games. No battery drain happening. It mainly depends on the apps you have pre-installed. Some apps are capable to use mic, or gps in the background even when they are not active. Any unrooted device is a potential privacy, and security risk, specially when you have facebook and google apps installed.

build number please!!!
The august build
I am getting over eight hours sot. Now also a tip is to calibrate the gaming app to battery prefer and then select samina mode on on all your games
Theae settings on you get no overheating issues also if you play retro games or name it's not too demanding on your CPU.
Also I have social media apps installed over 330 apps including games etc and utils.
No need to root the device at all. Thanks guys
There is a new firmware available. 64.0.A.8.25 I am not going to try it, i don't want to root and reinstall my device from scratch. Mine only have 40 apps installed, mostly root related. Nothing allowed to run on the background, except call recorder. All my apps only have internet access if they are in the foreground, except my banking app and skype , icq . The device does overheat when the camera is active for a while, however I only have it about a week.
