Holy cow !! That is excellent battery life. When I was on PA 2.55 I used to get 4 hours MAX !!! nothing more than that. How or what are you doing to get this !??

I know how you feel man. You are not alone :crying:
[Galaxy Note GT-N7000 General] cyapalmpos:
How about charge time? I'm on Alliance Alpha 3 (based off XXLSA) with Robbie's and Ficeto's TWRP kernel. I was at 10% and plugged it into AC 6 hours ago. I'm at 98%! Fuuuudge

EDIT: It was my cable. Disregard.

Sure, but after you implement paranoid setting into your ROM :D

lol, I thought that was automagically done :)

A relationship is like a house, its needs good foundations and trust is one of them.
[Galaxy Note GT-N7000 General] rraaka:
when i used paranoid 2.50 with the unnamed kernel i got pointed icicles on the battery graph as seen in gsam app, used to charge really fast but discharge equally fast too :laugh:

using latest leak lsa eybees rom i got absolutely straight horizontal lines for phone in standby, could be placebo but even more so with the unpatched kernel.

whats the optimum percentage you get for a 'good' rom in gsam app ? for overall apps and then individually for kernel and android ?

That's pretty decent. A steady drop :good:

Could you tell me how long it last at 100% when fully charged. So far, mine drops like 5 seconds after i unplug it. :crying:

With a full 1080p movie, 20mins of games and 30mins of youtube and the rest is just twitter and web browsing. Probably got about another 1.5 hours of screen time with light usage.

I was purposely running my extended battery down while running CM10 to calibrate.

Screentime was 6 hours on 100% screen brightness, with 25% remaining when I went to bed.

I've lost my battery anxiety - very weird feeling!
[Galaxy Note GT-N7000 General] :
Is that a note or your 7 inch tablet?

How? :thumbup::D:eek:
[Galaxy Note GT-N7000 General] l.Urker:
Its actually really smooth at 800mhz. Not much different from my previous 1.7Ghz clock. Except in heavy games.

[Galaxy Note GT-N7000 General] ashkan_mc:
Notice OP ! what is your rom and kernel and are you using stock battery or what?
[Galaxy Note GT-N7000 General] tasriri:
third pic? was it a drain? my worst experience with paranoid android is battery drained issue.

I can used my camera as the system telling me my SDCARD full eventho I have deleted few files. I decided to restart and suddenly the batttery went from 60% to 9% after it finised boot up. I found out it was innaccurate as I tried to drain the battery to 0, but the percentage keep dropping and increase between 5 to 7% before it really drain an hour after that.

my current paranoid android ROM also can detect my external SDCARD, which I realized after I ran few OTA update.
[Galaxy Note GT-N7000 General] ashkan_mc:
No it is not drain ... strange for me too ... but for example when I go to bed it is 47% and 7 8 hours later after I wake up it is still 47% ... no drain at all ... of course on flight mode ... and of course I have the gold 3500 mAh battery ... I think there is some kind of false indication in PA for showing the battery ...
[Galaxy Note GT-N7000 General] l.Urker:
Wow thats ... bad.
[Galaxy Note GT-N7000 General] b4oshany:
Yea its the same for me...... if I don't use it much I get over qr hours usage but when I do a heavy usage I'm getting 2 - 5 hours usage.... I'm running jelly bean ultimate ROM v5

This is my battery status

Any comments? I have 4.1.2 official leak.

I feel that my battery drains. When I had 4.0.4 the battery really works!!!
[Galaxy Note GT-N7000 General] streetcrazy:
I got more than 5 hours of on screen time usage on my phone. Using Alliance LSA beta 1

Will post a screen shot soon. Ill use the phone continusely and post a screen shot of how long I can pull off from max 100% till 1% So far this is the best I got out of my battery. And I've tried ever ROM possibly available.
[Galaxy Note GT-N7000 General] Super Prince:
I do not have my bs now, but i do observed the following for the slim bean and chimera:

slim bean Rom + cm10 kernel provided + 3G only data active : gives the best standby time drain almost less than 1% per hour, but have bad onscreen time i could not get more than 3 hour at all.

chimera Rom + HC STD kernel provided + 3G only data active : bad standby time drain with 3G mobile data 6% per hour, but have awesome on-screen time i get +4 hours.

I did not have any wake locks problem so i am confident with my results

Now i am using XXLSA 240 dpi Rom with no significant wake locks but bad battery life while on 3G, with WI-FI the battery seems to be much better

[Miscellaneous Android Development] edgardurao:

Yes, only the simple camera won't work.

[Miscellaneous Android Development] edgardurao:
Had to revert to stock after trying the kernel. For some reason the internal sdcard was in external sdcard.

As i could not change that, reverted to stock to fix this. I don't know why, since i tryed a lot of setups this weekend.

Guess later i'll reinstall it again.

But yours is amazing. Had tryed XTeam jelly bean, CM10 from vurrut, tokii (?) which didn't install, and this i think was one of the best.

The DPI at 160 is perfect for me. The obsession for 120 makes everything small, and since most of your things are compiled natively to 160 it works great.

Keep the good work. Only camera is the problem, but is a good start.
[Miscellaneous Android Development] Oma7144:
Yes must be ;)

By default you have 2.3 GB internal storage, the intSD is stub and the extSD is mounted as NAND (with 2048 kb buffer).

Hello again Oma.

So i reflashed all this, with the Kepler2 Kernel, but ended up with no sdcard available, like yeasterday.

So it's a kernel thing? Every app that i use complaints about no SDCard mounted.

How can i fix this? Aprecciate if you could help.

Durão
[Miscellaneous Android Development] Oma7144:
Should not be. Did you install the format_NAND fix?

- Oma
[Miscellaneous Android Development] edgardurao:
Yup. The 1.2 version. Flashed all witk rktool, replacing your kernel.img with the one you gave above.

All worked, camera too. But the sdcard problem continues. To have sdcard i have to put a micro sd in the tablet.... and the remaining 4GB... well i dont now where they are!
[Miscellaneous Android Development] Oma7144:
Ok let's change the mount-points. Fix to be installed by CMW.

- Oma -
[Miscellaneous Android Development] edgardurao:
So, some feedback regarding BQ Kepler 2!

First of all many thanks for your script, mount points correct now!

- Camera Working, if i change the picture through Google talk i can see me, no vertical/horizontal flipped. Only there's no Camera program :)

- HDMI works very well. However i don't have any hdmi options like in stock but works well.

- Usb host controller. Connected a Logitech wireless keyboard and mouse and worked well. When connected the wireless pen device rebooted, but after that the keyboard and mouse could be used without problems. Repeteaded the disconnect/connect and another reboot.

- USB OTG - connected a usb pen, and used USB host controller program to mount it. No problems seeing the files.

So.... this is perfect :)
[Miscellaneous Android Development] djkail:
Thanks OMA. I will test this kernel when i have time. Thank you so much.

Same here with 'Recent button' and Theam chooser app. But the app fc on all of my roms after deinstalling themes.

But the OMA CM 10.1 V1.22 runns very smooth and fast on my Prestigio5097Pro. Much better than old JB releases. Only miss the HDMI feature, but that's not a big problem. ;)

Update: Fond the solution for my theme problem. Check this link

I recognized the last days, that the display of battery consumption acts crazy.

I've tried to reproduce the behaviour and got same results. Fully charged and only used WiFi, Twitter and Tapatalk app.

First 30 min -> 30% ** 60 min -> 42%

With old JB 1.2.4a OMA ROM it was better. Same time only 20-30% in 60 min. Also I got after some time not using the Tab more accu as before.

Also I think that when battery is low, the calculation is more reliable as when full charged.

Could it be that the calculation is not correct?

See pictures for the last three days.
[Miscellaneous Android Development] User_99:
Battery status acts really crazy :sly:

What I've did:

Full charged and disconnected power cable while screen off (at 22:00)

In the morning I activated the decive and checked Battery drain. I recogniced that I've lost ~ 12% over night but Battery stat shows not the stats from 22:00 -only from morning 7:33?
[Miscellaneous Android Development] Alonso1398:
lol. My battery is working fine, maybe you could try using Battery Calibration

Also, installed v1.2.3 . I don't know if it's me but I feel it more stable :p
[Miscellaneous Android Development] User_99:
Must be device specific. Do you have the same device?

V1.2.3 of CM 10.1? :D

Thx for the hint?

Yeah, probably is device specific, I have an AOC MW0711 and you can download v1.2.3 here

v1.2.3 looks quite good. No need of battery fix for my tab, Works out of the box. Will test the next days and report... :good:

First question: use Phablet UI fix and have Mobile network activity. Not in CM 10.1 V1.2.2 My device is WIGI only ;)
[Miscellaneous Android Development] User_99:
Ok, looks like that I have in 1.2.3 also battery spikes.

Jumps from 9% to 33% only turn off the screen - no power plugged in - and wait about 30 - 45 min.

How about the 'Mobile activity' in battery stat and 2G/3G options in SystemUI.apk? Any fix to remove these settings?

Can anyone help me a little? I'm trying to create a kernel (or something like this) with the several utilities available but I still was unable to flash anything that is working. I have checked dozens of guides through the forum but none is working so far. A brief guide (or the place where I can find one) on the steps I should take it will be very welcome.

[Miscellaneous Android Development] User_99:

My Tablet do not have a mobile hardware - no 2G/3G. In your JB Roms an CM10.1 v 1.2.2 I also do not have the settings for mobile networks and not shown in battery stats
[Miscellaneous Android Development] Oma7144:
Both should work with you now.

[Miscellaneous Android Development] User_99:
Maybe I was not clear enough: My Tablet do not has a mobile hardware - no 2G/3G HW build in - its WiFi only. BUT, I have the settings in SystemUI.apk for mobile network and do not need these. I also got in Battery stats mobile connection always shown as inactive (red line). Neither need I this.

In your older JB Roms an CM10.1 v 1.2.2 I also do not have the settings for mobile networks and not shown in battery stats - and that was/is OK for me.

So my question is/was: Can I remove these unneeded settings / information in latest v 1.2.4 ROM?

Odys Loox cRom v1.2.4 (updated sources)

Something have gone wrong with this version (v.1.2.4) compared with previous version (v.1.2.3), ¡it has become terrible slow!

I tested it with Antutu 4.0 and gives a poor 2335, testing v.1.2.3 it brings twice the rate 4532, which is considered good..

I kept every version installed so I'm using 1.2.3 right now.

---------- Post added at 03:46 PM ---------- Previous post was at 03:20 PM ----------

I posted a comment like this in other thread (I can't find it again)

Anyway present version (v.1.2.4) is slower that previous (v.1.2.3)

Antutu 4.0 for v.1.2.4 ... 2335

Antutu 4.0 for v.1.2.3 ... 4275

So I'm using v.1.2.3

More comments...

v.1.2.4 ... USB mass storage work fine for External SD card.

v.1.2.3 ... USB mass storage not working

Anyway, you're doing an excellent job pal!
[Miscellaneous Android Development] Oma7144:
Hm, Antutu works fine with me in v1.2.4.

Also mass_storage in v1.2.3 (TabletUI) is working for external storage.

[Miscellaneous Android Development] DaremoS:
I think it's a problem with the kernel, I'm using that original 820c.(Master-G 820c = Mediacom 820c = Yifang M900HC).

I would like to test with the one you changed for 820c3G (crewrktablets_kernel_308_M820c3G_201301211220_CM10) that work fine in my tablet.

It just I would like to know how can I install this new kernel, without reflash the whole ROM.

(I'm in windows 8.1, and it's very tricky to flash android RK ROMs) *** EDIT I've read how to do this in other of your threads ***)

Anyway I install in v.1.2.3 the patch you posted for v.1.2.4 Tablet UI and it do a very strange action: after reboot it does an long upgrade of Android.

So I think that I have right now v.1.2.4 in my tablet.

TIA
