Battery charging anomaly?

Like some other users I've been under the impression that my phone is charging quickly, so today I've timed it and come up with an apparent anomaly that someone who knows battery technology might be able to explain.

Phone configuration: 20150711 rom + 20150718test kernel + heapsize changes (post #7976) + middle-aged battery.

Tests carried out with: phone network on, wifi off, bluetooth off, Greenify on.

Test 1 : Charge from 15% (when low battery warning comes on) to 95% (good enough to put in your pocket).

Time taken = 97 min.

Time to charge 1% = 97/80 = 1.21 min.

Test 2: Charge from 1% to 100%

Time taken = 189 min.

Time to charge 1% = 189/99 = 1.90 min.

Can anyone hazard a guess as to why the difference?

does'nt work power button

re- upload still does not work please help

sorry my bad english :(
[Galaxy Note GT-N7000 Android Development] bauner:
Have you tested to flash back a stock rom to ensure that your power button is not damaged?
[Galaxy Note GT-N7000 Android Development] bauner:
As my battery charging speed is ok I did not do much testing about charging current/time...

But the charging current is not linear.
[Galaxy Note GT-N7000 Android Development] tamaraxxx:
My phone gets fully charged within 3 hours, from 10% until 100%.

Using latest kernel and ROM together with ksm and zram enabled.
[Galaxy Note GT-N7000 Android Development] bauner:
Do you really need to enable zram and ksm?

How long is your battery life?

You can also try to change this line in /system/etc/init.d/01ksm

echo "500" > "/sys/kernel/mm/ksm/sleep_millisecs"

to this

echo "1500" > "/sys/kernel/mm/ksm/sleep_millisecs"

to make ksm more battery fiendly.

I will also release a new testkernel for the next rom soon which should fix a few problems and the higher battery drain from the thermal throttle workaround
[Galaxy Note GT-N7000 Android Development] tamaraxxx:
Battery life is great for me (see image below), use zram and ksm to use heavy apps.
[Galaxy Note GT-N7000 Android Development] bauner:
ok... I hope that the next testkernel will lower the android os battery drain....

They will be a few changes which should increase the battery life. If there are no new problems the next testkernel will be the default kernel for the next rom
[Galaxy Note GT-N7000 Android Development] nursoda:
I don't have such a big drain, on latest test kernel.

But I have another question: after trying Twilight and CF.lumen I noticed that the ROM also has a redshift feature (in system settings - display. If I set it to night, I see it immediately. But I can't get it to do it automatically. Guess I'd need to enable network based location (which I don't want) or enter my geoposition manually (which there is no setting for). So I stick to CF.lumen - or is there an easy way to get automated redshift?

I use 2.4 ampere charger....and phone get charged to full in 1h 40min....now sometimes at night i plug in charger and go to sleep..i have samsung original battery..i am on 20150711 rom and kernel(nightowl)..

Ques. - 8 hrs of overcharging will damage the battery or not ? Some people says smatphones are smart enough to stop charging when its full..but i use a 2.4 ampere charger(stock samsung charger comes with 1 ampere)..are there any negative effects for overcharging with a heavy charger or not ? If there are..then battery will b damaged or phone also ?

[MENTION=799465]bauner[/MENTION]: What is ur view as a developer ?
[Galaxy Note GT-N7000 Android Development] :
General rule is not to overcharge, most smartphones will stop charge then allow a slight drain then recharge again. That's like a continuous 99%-100%
[Galaxy Note GT-N7000 Android Development] Icetea:
most manufacturers stop charging if the battery has nearly 95% of charge. But the phone shows 100%! (because they want avoid complaints of angry customers :D )

maybe this information will be helpfull too: https://www.androidpit.com/how-to-calibrate-the-battery-on-your-android-device

BTW: yesterday i try to recharge my phone connected to an usb port. After a short time the display of my phone shows the information: "recharging will be finished until 12 hours"

i was starting at 40%!!! So i realy should need to wait ~12h for 60% of charge? That’s nearly 30% more than before!!!

Don’t forget to read my signature!:D
[Galaxy Note GT-N7000 Android Development] Shripal17:
You should not overcharge your phone. And especially you should not keep it for charging the whole night. Earlier my dad used this note phone. He used to keep it for charging whole night and hence the battery has degraded a lot. On continuous usage, 100% battery goes low to 0% in just 3 hours. And by continous usage, I mean whatsapp chatting, Facebook 'LITE' version, some instagram and some surfing (which is usually checking this post from bauner on xda)

And as far as using a higher current charger is concerned, I use xiaomi charger with 1A output which is same as Samsung default charger. And I don't have a higher current charger.

So, the conclusion is: DO NOT EVER OVERCHARGE YOUR PHONE

button doesn't work

restored to the original rom does not work it is not a mechanical failure , acted before installing 5.0
[Galaxy Note GT-N7000 Android Development] D@rekills4:
[MENTION=799465]bauner[/MENTION], I too am having issues with the power button if you remember. Pressing it sometimes makes the power button to be held out continuously until the phone reboots.
[Galaxy Note GT-N7000 Android Development] KalZakath:
It is a hardware issue. I had that problem too. Pulling button with little scissors help in my case.
[Galaxy Note GT-N7000 Android Development] Shripal17:
I don't think that's a hardware problem. Your phone directly reboots when you long press the power button, right?
[Galaxy Note GT-N7000 Android Development] clod22:
If you could not power on/off screen, that your button must be changed.
[Galaxy Note GT-N7000 Android Development] Shripal17:
Check if this file exists: efs/FactoryApp/keystr. Use Root Explorer or such apps.

If the file doesn't exist, then create a file using Root Explorer in /efs/FactoryApp/ with the name 'keystr'. Open it in text editor. And write 'ON'. Then save and exit. Reboot and see if you get the power menu on long pressing power button.
[Galaxy Note GT-N7000 Android Development] D@rekills4:
I will try that out after I check out Shripal117's solution.

Yes, it does reboot by pressing it once to lock/unlock sometimes keeps the key pressed and eventually rebooting.

I can use the button for power on/off of the screen. The issue shows up like once in two days.

No, that files does not exist but my power menu shows up fine. Pressing it once (not long pressing) keeps the button pressed and then it reboots.

Hello [MENTION=799465]bauner[/MENTION],

I've been using the 20150711 ROM + 20150718 kernel for a few days already,

Most of the time it works fast and smooth, but after 1 and a half day uptime, it becomes laggy and i need to reboot to make it smooth again, also updating facebook app always goes error, need to repeat it a few times until it successfully updated (actually i don't know if it's successful or not, there's no notification).

Is anybody experiencing the same problem?
[Galaxy Note GT-N7000 Android Development] Shripal17:
You can try making that file, if that doesn't work, then try the other solution of using scissors

I didn't buy a new battery recently. I have two batteries. The old one is a bit swelled up. The other one is normal thin.

I have zRAM enabled on 20150718 kernel. I have disabled KSM as requested by Sir bauner :) _/\_ and I didn't notice any difference in performance with KSM disabled.

Facebook lags a lot. You can try facebook liye. I use the liye version. I had the normal version, I uninstalled it due to the lag.
[Galaxy Note GT-N7000 Android Development] nokiamodeln91:
Use a 1A or a 2 A charger... the current accepted by the phone is only ~.0.98A±0.02A. Ya but agree with the fact that the phone shouldn't be left on charger for long periods after full.

Surprising, that everything goes well for a while, then slowness on slowness.

hello,

First of all thank you for supporting our good old man notes. I installed l version 150711 then the kernel 150718 with no problem at all. Nevertheless, today in the afternoon to have left very quiet note, he had difficulty in waking up (slowness, applications which do not answer any more). It has needed, five good minutes to be able to use the telephone. Surprising, that everything goes well for a while, then slowness on slowness.

Bonjour

Tout d'abord merci de soutenir notre bon vieux note. J'ai installé l version 150711 puis le kernel 150718 sans problème. Néanmoins , aujourd’hui après-midi près avoir laissé le note bien tranquille, il a eu du mal à se réveiller (lenteur, applications qui ne répondent plus) . Il a fallut , cinq bonnes minutes pour pouvoir utiliser le téléphone. Etonnant, que tout va bien pendant un certain temps, puis lenteur sur lenteur
[Galaxy Note GT-N7000 Android Development] nursoda:
Concerning overcharging: the phone (and all ROMs i aver used) handle charge stop / recharge after a little drop perfectly. Since I own my Note (it's a used one), I have it in my dock most of the time (many days, and all nights). My batteries last at least two years (it's the second battery now), so there is no issue with overcharging anyway, is there?
[Galaxy Note GT-N7000 Android Development] bauner:
Maybe later. There are some missing parts in the driver which needs to be added

Maybe an app is causing this for you? If it will happen again please post a logcat and the dmesg log

Try using greenify with xposed and auto-hibernation enabled. Hibernate the apps which you don't use frequently. That way those apps will be closed and won't consume cpu or power.

When I open the xposed installer app, it says v65 installed. I have greenify module enabled. But when I open the greenify app and try to tick any of the settings which requires xposed, it says module not activated. Don't know what this problem is. Been facing this problem recently after installing 20150711 ROM (currently on 20150718 kernel)
[Galaxy Note GT-N7000 Android Development] farhanzahinfj:
Solved it. In system/data/data/rovo...xposed.../config/ there is a file named 'disabled'.. I deleted that.. Now xposed works again. Donno how that got there.

And if that doesn't work for you/ xposed already activated... try to update greenify. Older versions have that problem.

[Galaxy Note GT-N7000 Android Development] mucaco:
Apropos of the battery saver app, Bauner has the right, why he does not use none.Also in my case, I tested many app inc. greenify, just opposite effect. All they do is kill some apps and services. And when you need those again, it uses much more battery, to start them, than it would have used if they were not killed.
[Galaxy Note GT-N7000 Android Development] :
You guys may want to try this if you think your battery is drained all too fast. It's the equivalent of Stamina mode for Xperia phones, stopping wakelocks and services when the screen is off. You can select which apps you want to continue as usual so it won't interfere with anything.

Re: [ROM][CM12.1][Lollipop][Android 5.1.1] NightOwl 20150711

Did a manual wipe via format of data, system, and cache - then clean installed ROM, test kernel, and Open Gapps today = root seemingly lost (no # symbol, OS Monitor not working, titanium backup behaving strange then reporting no root).

Resolved by flashing SuperSU - feels a rather inelegant solution...

[Galaxy Note GT-N7000 Android Development] :
Correct. Kill tasks will only consume battery as the app has to restart, Greenify DOES NOT do that. Instead, your apps will not run until you wake your phone but you may still receive notifications only when they are detected.

You are right about greenify related to kill tasks.I just told my personal impression after a few days of use (higher battery drain, phone heating up).
[Galaxy Note GT-N7000 Android Development] hfdesign:
best app for killing task and services without drain battery is servicely

servicely app better than greenify

this is very very good app

work in cm12.1
[Galaxy Note GT-N7000 Android Development] Icetea:
that is your opinion not my!

"Greenify" can do his job without root, "servicely" not!

And i think it is better apps to hibernate as to kill them.

You can use amplify+greenify+powernap for best battery life

Here is the thread http://xdaforums.com/android/general/guide-extreme-battery-life-t3095884
[Galaxy Note GT-N7000 Android Development] hfdesign:
greenify can't kill system services

for example you can't stop service of system wallpaper of launcher or can't stop billing services of google play services only or many many another services

servicely very very low memory used

when greenify killed task after few minutes apps running and killing them another time but servicely before running app can stop running apps

i testing both apps but with greenify my galasxy note is slowing and with servicely more than greenify ram is free.

Feature request: alternative brightness settings.

A brightness slider that dims the display similar to moving the colour calibration sliders to the left.

Basically something like the screenfilter app.

The reason for this is that the black clipping fix (which is really just changing one value) disables the driver brightness settings. This and a better colour calibration (which I will try to take care of) are the only things holding back our displays.

Also a somehow related question: How many people actually do not have black clipping?

I read that some n7000 (mostly white ones) have no black clipping at all. Is that true?
[Galaxy Note GT-N7000 Android Development] nursoda:
What exactly IS black clipping?
[Galaxy Note GT-N7000 Android Development] ruleh:
A big fail in gradients.

It is like this

white->light grey->grey->grey->black->black

as opposed to

white->light grey->grey->dark grey->very dark grey->black.

It is usually seen as black ptches on images and videos.

This explains it better

It can't be that the white models don't have black clipping. Its a software issue which causes black clipping I guess. I have a white note. I have black clipping.

The battery life in the next kernel will be better as with the 20150718 but it will use a little bit more battery in standby as the 20150711 too.

But in my tests I get 48+ h without recharging on very light usage with sim card and enabled wifi and no battery saver apps.

I think this is ok...

For me it is more important to have a fully working thermal management in all cases (to prevent a device damage in the worst case) as 1-2h more standby time...

Here is the new 20150726 RC1 kernel based on the stock samsung source.

It should work well and will be the default kernel in the next Rom release

Changes 20150726:

better fix for the thermal throttling problem

fixed some wrong defines for mali r3p2

Changes 20150718:

Many updates on the kernel memory management which should make everything smoother.

Workaround to fix thermal throttling (http://xdaforums.com/showpost.php?p=61912556&postcount=8061)

Network indicator arrows fixed

Removed some logspam

Updated usb gadget driver

ondemand: cpuidle detection

Some netfilter updates

On the installation of this kernel the filesystem of the system partition will resized to use the max possible size.

Also some build.prop values will be changed to fix some not workings apps like 9gag and fix the trebuchet fc if you change the scroll effects.

It will also disable ksm (please try it for some time without ksm. If you really want to re enable ksm you can use the zip file from the first post)

I would suggest to make a backup of your rom in the recovery before you flash this kernel if something should go wrong!
