That's a high drain - 20% load in 1 hour rest. You can watch the battery consumption very good with BetterBatteryStats. Look if your phone goes into deepsleep mode. I attach you the XDA edition, check it out.
[Galaxy S II Android Development] xn0live:
can you upload your BBS to see how is the battery life

[i9100] Useful fixes for LineageOS 14.1

Adding and fixing in a new format, for [i9100] Useful fixes for LineageOS 14.1
[Galaxy S II Android Development] sbappi:
Thank you so much! You saved me from flashing XOSP again.:victory:

I also do the same thing and somtimes thrice a day.:silly:
[Galaxy S II Android Development] Nobby1960:
Yeah - and here comes the hard reality ;) Reading a German newspaper ("Die Welt") with the Gello browser, a lot of reader comments, I had to scroll every second. My Kernel Adiutor is adjusted to 1200 MHz - AICP ROM, build 02/07. The battery is an older one: 2013/12/13. The browser eats a lot of power.

Edit: I forgot to calibrate the battery, the charger (an other S2) shows me 34% rest :silly:
[Galaxy S II Android Development] xn0live:
thanks for that

2 hours is not very amazing why it use always 1200mhz damn :eek:

---------- Post added at 07:32 PM ---------- Previous post was at 07:29 PM ----------

how do u exactly calibrate can u explain it
[Galaxy S II Android Development] linusdan:
I loaded my I9100 and installed the KernelAdiutor (did not change any configuration) besides the BBS and left quiet for 18H. It consumed 37% of the battery with DeepSleep mode. It is already an advance with what was happening previously (20% in 1 hour rest). But still worries, since with the Stock only unloads of 3 to 4% in 18H. [MENTION=7513127]Nobby1960[/MENTION]
[Galaxy S II Android Development] Wandeta:
1.There isn't any application

2.I uploaded the rom again

3.Night %100

4.Morning %76

5.The battery is copy but new

6.I didn't use the phone this time

7.Hour 21:26-4:16
[Galaxy S II Android Development] xn0live:
wow only 10 min??

Did u see BBS ? upload it here
[Galaxy S II Android Development] Wandeta:
I don't have bbs
[Galaxy S II Android Development] Nobby1960:
The calibration is very simple with this tool.

I mean, your value after 18 hours of deep sleep is quite okay for Nougat. I test it again with my phone and AICP. The stock ROM needed significantly less power.

Just look here to download it.
[Galaxy S II Android Development] xn0live:
did the caliration really help ??

I have a queestion how long need it if ou charge u phone? in 10 min it charge by me only 2% is it normal? i test also other charger

---------- Post added at 01:31 PM ---------- Previous post was at 01:30 PM ----------

how u get it??

1650 accu?

wlan always on?
[Galaxy S II Android Development] Nobby1960:
The calibration only compares the values of ROM and recovery. Under Lollipop, I was able to use Synapse to make a so-called "fuel gauge reset". This feature must supported by the kernel. There is no supported Nougat kernel yet.

The charging time I have not yet checked. I have here the original Samsung charger and five 1650 mAh batteries. At least one battery must always be full to test :)
[Galaxy S II Android Development] xn0live:
ok i will test it
[Galaxy S II Android Development] ssanjy:
I've been using the app FuelGaugeTool to calibrate my battery ?... It seems to work fine to me in Nought as well... Currently I'm on this ROM.... It's good and stable but the battery drain in idle is on higher side... Nothing shows up significant in BBS... My battery is a copy Battery though purchased about ³ months ago...Also I noticed that the phone doesn't go to the "doze" sleep where the battery drain during idle time was really very minimal....I last experienced that in DU MM.... Especially during the night time...
[Galaxy S II Android Development] xn0live:
that mean its the rom/kernel because of the battery draining?

---------- Post added at 05:57 PM ---------- Previous post was at 05:47 PM ----------

Maybe that worked

echo 'N' > /sys/module/msm_thermal/parameters/enabled

echo '1' > /sys/module/msm_thermal/vdd_restriction/enabled

[Galaxy S II Android Development] Nobby1960:
Yeah, thank you - this app seems really reset the fuel gauge chip on hardware side. A typical sign of this is that the battery drops after reset a few percent in the ROM and you have to reboot the phone.

internal shared storage

Good morning everyone :) Thank you Greek Dragon for sharing this wonderful Rom for all the S2 users still out there.I'd like to ask in this forum if after flashing the rom through Twerp is it normal that the Internal shared storage shows 9.36 Gb occupied out of 14.68 or have missed something??

problem with re installng whatsapp

the rom is ok but when i try to reinstall the backup of whatsapp dont' do that because it's a custom rom? problably?
[Galaxy S II Android Development] Tilagoon:
Try to install the Whatsapp application from the Playstore then when done try to restore the backup, it might work.
[Galaxy S II Android Development] xn0live:
u get always screen on over 3 hours?

do u change anything?governor?
[Galaxy S II Android Development] The Weeping Angel:
Thank you Toy Story for your reply :) Installing Diskinfo I see that only 7 Gb show up in the information screen when instead the rom storage screen shows 14.68 Gb of shared storage.Having previously changed the storage size using .pit files on stock what am I missing here? The used 7 gb are showing up as system files which I think could be due to an error in installation,even if the rom seems to be working perfectly well.
[Galaxy S II Android Development] luckyduan:
good work ! plz don't stop:D
[Galaxy S II Android Development] PackElend:
I had the same problem but solved it see here my post:
[Galaxy S II Android Development] Nobby1960:
WhatsApp works here without issues on any LineageOS-based Nougat ROM. Only at start from installation there is a message, that custom ROMs can make problems, but you can ignore that. The WhatsApp support doesn't like custom ROMs and all rooted devices generally, that means you don't get any help from them.
[Galaxy S II Android Development] MigoMujahid:
The only issue in WhatsApp is sound/voice recorder, it records a very low sound.
[Galaxy S II Android Development] Nobby1960:
Yes - you're right. I have here still another S2 with Lollipop and would like to try out whether the voice recordings with the same WhatsApp version are also so low.
[Galaxy S II Android Development] MigoMujahid:
It works good in marshmallow and lollipop even in the same version, i believe it might be a compatibility issue with the app to the now android 7.
[Galaxy S II Android Development] PackElend:
[MENTION=7373664]imo73p[/MENTION] and [MENTION=7432167]noratroll[/MENTION] talking about repartitioning, have you ever considered switching from non-emulated to emulated internal SD card?

I haven't tried because nobody hasn't been able yet how Android handles the allocation of apps if you have also an extSDCard. The background is when you use streaming apps like spotify , podcast apps and cloud services (all with offline storage) you will hit the max. /data partition size limit, later or sooner.

Hello

I've installed the latest version of RR on my old i9100. All works great, but I couldn't find the pitch-black settings. How to get a full dark theme (especially the phone and sms apps)?

Thanks
[Galaxy S II Android Development] Wandeta:
Apps can't see external sd card1 how can I fix this?

sdcard1
[Galaxy S II Android Development] lexus46:
You can't find pitch-black settings because RR Nougat doesn't has the CM themer app like in Lollipop or MM. You need to install Substratum and download some dark themes. Sadly pitch-black themes (which I like very much too) don't work with Substratum and it take a century to set up and apply a theme.
[Galaxy S II Android Development] zanmisel:
Substratum pitchblack origin theme just released today on play store

https://play.google.com/store/apps/details?id=pitchblack.origins.westcrip
[Galaxy S II Android Development] Wandeta:
I uploaded Themes but I can't use it
[Galaxy S II Android Development] zanmisel:
you mean Download themes??you have substratum legacy theme engine to use them?

https://play.google.com/store/apps/details?id=projekt.substratum&hl=en

but in my s2 newest substratum doesn't work because rom doesn't updated with latest changes so i think it is better to install these untill s2 rom gets latest update..http://www.apkmirror.com/apk/projek...ive-hundred-sixty-three-android-apk-download/
[Galaxy S II Android Development] John D J:
Do not use substratum. Its awful. It cause your phone to crash and you to reset everything. The theme tank on cm was vastly superior. Leave substratum it's really bad news.
[Galaxy S II Android Development] lexus46:
That's why I still stay on Marshmallow. I can't give to my S2 the look I want.
[Galaxy S II Android Development] ssanjy:
I'm using substratum theme DNA Dark Project and its running great....I have enabled selected theming and haven't face lag....But I think once I applied theme in the phone app and I did find few issues... So I did selected theming in settings and few apps like XDA, gallery, etc. Substratum is in continuous development whereas CM theme seems gone for the newer versions of Android... So it'll be streamlined in the near future.... Till then it's our decision to use it or not...
[Galaxy S II Android Development] EB10000:
Substratum crashes on opening on i9100...
[Galaxy S II Android Development] Salamender:
Hello, same for me, Substratum crash at launch after the little animation, there is a way to get it working ?

Thanks
[Galaxy S II Android Development] Nobby1960:
It's possible that this firmware archive is damaged. In the LOS forum someone had the same problems with this ROM, as soon as the NAND writing started it fails. Try another firmware from SamMobile, you just must register, it's free.

Edit: Ooops - I've read that you've already tested another stock ROM (now I remember). Then it's probably in the direction of hardware...
[Galaxy S II Android Development] ssanjy:
Try v 563 from apkmirror.... I've got the latest working after installing 563 and updating via playstore
[Galaxy S II Android Development] Salamender:
Thanks, it works but I can't apply any theme cause I'm in legacy mode.

RR doesn't support RRO or Substratum ?
[Galaxy S II Android Development] Nobby1960:
[MENTION=6518445]silvers01[/MENTION]

Perhaps I have a solution for you, to fix your flash and NAND write problem. Try to flash this older Siyah kernel for the S2 via Odin in my attachment. If it works, flash a stock ROM again. Good luck!

guys how much it needs too charge from 1-100%

round about3-4 hours?
[Galaxy S II Android Development] Nobby1960:
Yes, this is a realistic value.
[Galaxy S II Android Development] xn0live:
its not possible to make it faster or?

How much u phone need
[Galaxy S II Android Development] Nobby1960:
As a rule, the battery is enough for me a day if I don't do straight installations. In the night it is charged. By the way: I'm testing now the battery consumption of the latest AICP build from today. It seems to be higher. Build 02/07 has a really moderate consumption.
[Galaxy S II Android Development] gixik:
This is what I've done to get substratum working:

1) Install substratum,

2) Install theme (in my case it was Default Dark Substratum Theme' but i guess it will work for any theme),

3) You should get substratum notification in the status bar that the theme was successfully installed,

4) Tap on the 'new theme installed' notification, now substratum should open normally,

5) Make sure substratum and masquerade have root privileges and substratum has usage access permission (I had to switch the permission off and on again, because I received some errors when compiling and applying overlays).

Hope it will work :).
[Galaxy S II Android Development] xn0live:
higher of what?
[Galaxy S II Android Development] Nobby1960:
The of all battery consumption - even in standby mode. But I still have to test exactly.
[Galaxy S II Android Development] linusdan:
My tests so far with custom rom (Nougat, battery life with intensive use for music, instagram and playing 2048 and Gangstar Vegas. Dalvik/cache clean! charged in 100%):

RR N build Mar 01: 4H

LineageOS build Mar 15: 4H15

XOSP N : 2H (I've seen test here for 6 hours, but in mine it did not happen)

XenonHD build Mar 19: 6H

In Standby (no wifi, mode battery balanced):

RR N build Mar 01: 17H30

LineageOS build Mar 15: 1 day 22H

XOSP N: 16H =(

XenonHD build Mar 19: 2 days

Upcoming ROM for testing (maybe):

AICP

LineageOS Mar 29

I'm currently using RR M 5.7.4 Stable.

The battery life is OK, 5H.

In standby: 2 days and 15 hours.
[Galaxy S II Android Development] silvers01:
Thanks for all the help mate :) ..i gave up already. Service center can't fix it too. i guess it is the so called "emmc super bricked bug".

Anyway To all people, beware of random reboots thats happening. It may corrupt your phone. Thats what happens to mine. :crying:
[Galaxy S II Android Development] Nobby1960:
Ouch - yes, the super brick bug tells me what. This is connected with a faulty eMMC chip, which is also installed in the Galaxy S2. Sh*t happens :silly: The cheapest way is to buy a S2 with broken display or a used mainboard at ebay.
[Galaxy S II Android Development] xn0live:

which rom u prefer about battery life and stability
[Galaxy S II Android Development] linusdan:
I mean 5 hours in heavy use :D

I prefer both.

Testing is fun, but having the phone without heating is too beautiful!
[Galaxy S II Android Development] gixik:
On RR 5.8.2 Kernel adiutor shows that the CPU speed is stuck at 1200 Mhz when screen is on. Is this intentional? When screen is off phone is in deep sleep most of the time, occasionally switching between 200 - 500 - 800 mhz.
[Galaxy S II Android Development] Tilagoon:
I hjave tried to apply this procedure but for me it doesn't work :crying:

Substratum keep crashing before asking for root permission !

I'll wait for the next build hoping that the problem will be solved !
[Galaxy S II Android Development] gixik:
Try tapping on the 'new theme installed' substratum's notification. Maybe it will help :).
[Galaxy S II Android Development] Tilagoon:
Hi,

Thanks a lot again!

Your tip is the clue to install substratum :good:

The whole install is a little bit tricky :victory:

So to resume the tricks:

- Tap on the notification about success install of the theme instead of launching substratum from its icon

- in setting/applications deactivate / activate storage access otherwise impossible to compile the overlays

- When compile is done wait for a while as install takes quite sometime !! (well its only a galaxy S2):cowboy:

With all this I have successfully installed DNA Dark theme :good::good:
[Galaxy S II Android Development] gixik:
I'm glad it works! I will edit my previous post with instructions as I've omitted this important step :).

RR M 5.7.4 5 hrs as i said.
[Galaxy S II Android Development] Ainarafely:
Thanks for this awesome ROM (5.8.2). I have an issue with camera : pictures are very foggy with the main camera and fine with the front one. Any solution?
[Galaxy S II Android Development] lexus46:
I think you are very lucky. I have original Samsung battery too from 2015.03.08. and with stock JB the standby time was 1-2 days. That's why I rooted the phone and started installing custom roms. With these and wakelock blocker I managed to reach 3 days standby time but never 7 days. Samsung itself realised that 1650 mA is too small for such a big display and released a 2000 mA battery that increased the standby time about 15-20%... I wanted to buy it but is discontinued. But 7 days... simply amazing.
[Galaxy S II Android Development] linusdan:
Wow! I did not even know about this Samsung story. Neither of your history. Now knowing their, I'm really considering myself a former user lucky of Stock ROM!
[Galaxy S II Android Development] Nobby1960:
Is that the larger battery, for which is a different back-cover needed? This I had already seen at ebay, but a longer time ago. 7 days of battery life I had never with the stock ROM (Jelly Bean), only if the phone was turned off ;) That's really very long.
[Galaxy S II Android Development] xn0live:
i have one its have 2500

i get with strong use 4-5 hour screen on but the phone is bigger and i like it small like s2 (original)

the other negative point was it need 5-6hours from 1-100%
[Galaxy S II Android Development] lexus46:
Yes, that's a larger battery. There are even larger batteries (3400 mA) from another manufacturers but I don't trust them and are really ugly. I saw pictures with them, the phone looks like a brick. Seriously, I don't believe that there is only one phone with touchscreen to resist 7 days in standby. Maybe in airplane mode with everything turned off. Or maybe it was only a joke from 1-st April.

[Galaxy S II Android Development] Nobby1960:
Are you on RR ROM? The deep sleep is very good in my opinion. Screen on: What did you do in this time - internet with heavy scrolling, mail reading etc.? I mean now after many tests that all LineageOS based Nougat ROMs round about from the same building period have little different on screen consumption values. Then it depends on what you are doing right now. Heavy scrolling on Google Play Store (down/up...down/up...) drains your battery like hell :D
