Adaptive charging bug - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

I just recently got the note 4 and imagined this phone would be amazing rooted but of course not a biggie but ever since i rooted it and i plug it up to the stock charger weather i have fast charge checked in the settings or not it always goes to fast charging setting its been doing it lately and i havent minded it but now i notice how fast my phone is dying and nownim a bit concerned on the fact its eating my battery life idk if anyone else has this problem or i just did it the wrong way i had used odin (first time in a while) and id think i'd root pretty solid i guess not its pretty buggy any opinions? Or answers?

Battery use and temp after root normally worse?

Hello all,
before anyone yells at me I did search and didn't find anything that makes sense cause this does seem common.
My battery life is still decent not as good as before rooting but I could live with that and not even over clocking is set to max of arround 990 or so but my thing is does seem like I am even just reading a book or the screen is on the bottom part of the phone gets warmer then it did before I rooted my phone.
I have tried different roms like modacos r22 desire r19 froyo, cyan 5.0.8, and rodreigez style and all seemed to have done it.
Seems ok when locked and not used for a while but with screen running for about 10 mins or so I can feel it getting warm. The stock unrooted frf50 i was on did not do that. Maybe recovery you think? Or should I just completely unroot put back stock recovery and all. Will be official then since I didn't unlock bootloader.
I am using setcpu from market and that is set to profiles
sleep 245-460 on demand
charge 245-883 on demand
fail 245-245 on demand
any ideas if I just did something wrong or do I need to flash a different kernel?
*edit*
also may be relevant since I live in 3g coverage I used to have the phone plugged in and download files and never leave 100% battery. Even with it undervolt kernel and not over clocked it drains now when I do this.
Anyone? And something else I noticed, if I plug in with more then 90% power to the pc it wont charge even though shows is charging till gets below 90% till 89 then will start charging. Any ideas?

[Think Tank] Modify Kernel to fix charging

I haven't actually looked at the battery driver or even the kernel for that matter, but does it specifically state the cutoff voltages for charging the battery? If it does, we should compare those to what the phone is charging the battery to when the phone is off and make them match. Hell if you want to live on the wild side bump it up another .05 - .075V or so...
Just a question.....but do you know what you are talking about??
Froyo seemed to solve the charging 'problem' for me, then again I never had a charging problem.

Erm, how did it fix it? We still have that problem.
I believe what he is talking about is modifying the kernel to allow the battery to fully charge when powered on rather than leaving the "buffer" which requires the bump charge to get the extra 10% or so out of the battery. I'd definitely like to see this as well, but I've found performing the recalibration did help a bit.
Disclaimer: I'm a noob and don't know ****!
However, it would seem if htc (or google), put code in the kernel to prevent the phone from charging to 100% while turned on, I'm sure they had good reason. My guess would be to keep the phone from over heating.
It would seem that if the phone is on and draining the battery, but at the same time you're trying to charge the battery, achieving that last few percent might be difficult and could take considerable more time, and thus getting hotter.
Just a guess though.

I'll look at the battery driver when I get home (currently at work), but I have seen devices where charging limits were invoked directly in the kernel. These could be modified if they are.
On the issue of heat, manufacturers play it VERY safe. It looks bad if someone is charging their phone in their car during the summer and the battery cooks off in the passenger seat. I'd be fairly comfortable pushing the battery to a little bit higher voltage than it is right now.
What about the charging SPEED? Myself and several others have noticed that Froyo ROMs charge at a much slower rate, plugged in to ac power, compared to 2.1 Rom. For me, it takes about twice as long to charge. Is this something that could also be addressed with a kernel fix? I literally went from being able to charge from ~10% to full in about 90 mins, to now taking about 4 hours on Froyo.

The 2.15 radio probably broke the phone's ability to differentiate between the wall-charger (fast) and normal USB (slow). The reason I say "radio" and not "kernel" is because it charges slowly when powered off as well. Hopefully the radio included in the upcoming OTA will fix this.
I had the slow charging problem on the 2.05 radio as well but doesn't change much about what's being said about a potential fix.
Anyone able to confirm that this (something in the radio) is the reason?
Hope the OTA comes soon so I can get back to recharging in a timely fashion.

Apparently you are one of the users that were lucky enough not to have this issue. This thread is not for you. Move on. And btw, Froyo did not fix this problem. Again, nothing for you to see here, move on.
For the rest of us who are interested in solving this issue we will continue to put ideas out there in the hope that a smart one figures this out. Until then, we will keep reading about how fortunate some people are and how some other unfortunate people are willing to work on this. Thanks OP.
the difference between bump charging and not never really affected me because the phone charged so damn fast, that just plugging it in for a few minutes helped out a ton. but now with froyo, it literally take 5 to 6 times longer to charge to 100%. its ridiculous
i got sick of letting my phone charge overnight then 10 min after i unplug it in the morning its down to 92%. and unless you charge it while the phone is off it rapidly drops all the way down to like 80% before it starts decreasing normally, at least for me. so i started turning it off and topping it off in the mornings for about 30-45 min before i would leave for work, doing this i noticed a HUGE difference in my battery life through out the day. that got to be a pain because sometimes i just don't have time to do that in the mornings, so i ended up buying an external charger and an extra battery. this way charge the extra battery overnight on the external charger, pop the fresh battery in the phone in the morning and i'm ready to go. but all this could be avoided if the phone would charge the battery as good as the $2 wall charger, so if you could find a fix for this battery problem it would be awesome.
I had slow charging with 2.05 and 2.15 radios, unfortunately...
Did any of you that are having this issue root and install froyo immediately after buying the phone? a friend of mine is having a similar issue. Have you tried battery recalibration? Also I would recommend checking your up time and awake times in battery info and see if there's something keeping your phone awake while charging . One last thing, try installing battery save mode toggle from market.

I've been messing with the slow charge issue all night tonight, and as far as I can tell, it is not the 2.xx radio, and it must be the .32 kernel.
Slow charging started for me when I installed the first 2.2 leak which had the 2.05 radio, and remained on the the 2nd 2.2 leak and 2.15 radio. Before that I had the 2.05 radio on 2.1 and charging was normal, tonight I rolled back to complete stock 2.1/1.0 radio and charging was normal again, I kept the 1.0 radio and installed a 2.2 rom, charging slowed again, changed to 2.15 radio, still slow, so I installed the old CM6 test 8 rom which was used the old kernel with the broken camera, and sure enough, charging was fast again.
I'd really love to figure this out, if any of you get on IRC and want to discuss this, /msg digi

Great work. on testing at least...
Is there anyone out there who can help fix this? I hate these slow charge times.
I thought the issue was that the phone starts running off battery one its at 100%, not that it can't charge the last 10%...am I misunderstanding that?
I've tested this by taking it off the charger as soon as the light turns green...seems I get much better battery life this way.
This doesn't quite explain why some of us have had no problems at all either. Maybe an issue with newer devices but personally my device has been up for over 31 hours since charge and haven't noticed this issue but a friend of mine has complained of it, and he recently bought his device. Tomorrow after I charge my device I'll post with findings after charging.

this has to do with 2.2 and new kernels. not stock 2.1.

I pre-ordered my phone and I have the charging issue as well so it can't be new phones vs old phones. I hope it gets figured out soon.

incredible s battery not soo incredible

hey everyone,
firstly, i just wanna say that the HTC Incredible S is a solid and terrific device, previously owning an iPhone 4 i might like the HTC better, except for some things...
The battery:
i read some reviews before buying and every reviewer seemed to love the phone and what the battery has to offer. I've owned the phone for a week, and charge it through the USB cable, connected to my PC, and sometimes the wall socket.
But it seems to me that the battery is a bit short.... if i want the battery full i will let it charge overnight, the next day i powered it on, sent a few texts and listened to half a song and the battery has already drained to 70%, coming to this from an iPhone 4 is disgusting.
I've got Auto-Sync and background data working, i like push notifications for Emails and Facebook and i like the weather to update on its own, also HTC sense incase i need to do things remotely, everything else has been set not to sync.
One of my favorite features is Auto Brightness, which is enabled on default, but when i check battery use it says that 70% has gone to the display, 12% cell network and everything else. I have a task killer that kills all processes when i turn the screen off..
Any help??
Wiping the battery stats a few times helped me, I used to recharge the phone to full battery and after unplugging it from the charger, it would drop to 94% in a few seconds...Oh, after 2-3 weeks, not after a week!
Also I get twice the battery life on Cyanogen 7.1, than on any other Rom I've tried...I get at least 2-3 days with good usage, tons of mails, sms, calls, weather apps etc. Wifi and BT always on. No juice defender or anything like that...
Dropping to ~95% can also be normal though. To preserve the battery the charging circuit should cutout when it reaches 100% charge and let it discharge to 95% before turning on again.
If you do wipe the battery stats make sure you read some guides and do it properly as I've found that more often than not it will have a detrimental affect (from needing to charge before it has fully discharged, or needing to reboot etc).

wipe the stats? sorry im still new to android but so far so good, im impressed with everything else in the incredible s, its very snappy and has a bigger screen vs iPhone 4.
if it helps, i have the phone fully turned off if i charge it overnight.
also, i read on another forum that while it's still brand new it needs to run a few charge cycles to strengthen the battery, if that is true.
It always drops to 95% when the battery is fully charged. S-ON Incredible S is not allowed to wipe battery status. Should I unlock it?
Yes, I forgot to mention...to wipe the battery stats you need to unlock the Hboot...If you have Hboot 1.16.000, then the only option is this:
http://forum.xda-developers.com/showthread.php?t=1337105
Unlocking the Hboot is giving you a few benefits, you get to install the CWM recovery and do a full backup of your Rom...Without unlocking the Hbtoot, if your Rom crashes, you can't flash any Rom so you have to send it back to HTC Service ...With the Hboot unlocked you can install custom Roms, you can restore a full backup, you can flash GAPPS etc, wipe battery stats directly from recovery etc etc...
So many benefits...
Now back on how to wipe the stats...The principle behind is simple, if 100%=4.3V and the stats are incorrectly set for 100%=3.9V, then you're never actually recharging the battery to full capacity, which is rubbish...
The way I do it is this - charge to 100%, boot into recovery and wipe the battery stats. Now use the phone until it's shutting down and then charge to 100% again.
Very important is to avoid rebooting the phone after the stats were wiped until the phone is fully recharged. Here is a thread about this process:

In my view, recharging while the phone is off makes no difference.
Yes, it's true. With all my Android phones I went through the same thing, first week or so, the battery was rubbish, but after about 2 weeks it improved a lot.
yeah, i've had it for around one week. so i might take your word for it and give it a chance, maybe for 2 weeks. i was thinking of bringing it back to the store but i'll give it a chance.
a part from the short battery at the moment it's a pretty terrific phone and i like it more than the iPhone 4.
Once the battery is conditioned, phone is rooted, custom Rom installed, bloat frozen out or uninstalled, then you can expect your phone battery to last a good full day with regular usage. No need to switch off when charging over night.
Well its incredible enough for me
It lasts a day, which is just right for me haha
Did u remove the USB immediately aft the charging?

well i've had it for almost 2 weeks now. I charged again overnight last night and used it to listen to music and play NinJump/Bejewled on the way home today, battery uptime was just over 30 mins and the battery was down to 70% remaining. That's a bit quick if you ask me.
Not sure what's happening with your phone...but my Inc S has really good battery life, similar to Iphone 4...
At the moment is not rooted (that's why I couldn't take a screenshot) and it's on stock 2.3.3. With BT and Wifi always on, with tons of e-mails daily, browsing, calls (at least 20 minutes per day), tons of messages, etc etc
Screen brightness is always set to maximum and I get at least 2 days battery life, see attached photo...
I'm not playing games or listen to music...so I can't test that side of things and maybe that's where the problem lies.
What's your Battery Usage app saying?
Is there anything unusual listed there?

Maybe try disabling the Optus bloatware. Had a bit of an improvement when I did it to mine. Also be mindful about what apps are running in the background constantly, they could also have an impact on battery life. Screen is a huge battery killer if its constantly on, autobrightness can help slightly if you haven't enabled it already.
Thanx everybody for the replies

That battery usage sounds awesome! I have mine on Auto Brightness and WiFi turned off but its nothing like yours. My battery usage app says most of it has gone to the brightness, of course that percentage goes down when i start opening apps.
edit: im also using the stock Android 2.3.3 installed from the factory. and disabled my Advanced Task Killer, battery is still the same, but the phone now lags a lot less. so thats a plus for now.

When i first got the phone i noticed Optus loaded it with rubbish apps i'd never even touch. I disabled auto updates for the bloatware and forced stop for all the ones running. it doesnt look like i can remove them though :\

Hi when you get such good battery life, could you show us how long your screen's on for?
do you get good reception where you live? i find that seems to drain most of my battery.

ok atm my incredible s is saying 4 hrs 26 min uptime and 1 hr 21 min awake time, 50% left. my signal here is great, the speed of the internet even beats my ADSL 2+ sometimes. should i be thinking of warranty back to store?
Before i rooted my phone i was charging my phone twice a day - this was nothing new to me as i had been charging my 3gs at least twice a day for the past two years.
However like somebody else has said, once the phone is rooted and all that optus junk has been deleted it lasts a lot longer. And you can notice the difference, my phone has been rooted for 2 days now and i have been on it none stop, modding all the appearence and downloading apps. I have been using it a lot more than i was before it was rooted and it has lasted at least twice as long. So for battery usage i should deffo root. Its HTC sense/screen that hammers your battery. Go look at battery usage and yourll see what i mean.
Also, i know this might sound stupid. But charging it through a wall socket (for me) seems quicker to charge, and seems to last longer than if its charged through a laptop/PC. Although ive thought this for my 3gs as well. If its actually true i dont know haha.

sounds just about right. my iPhone 4 needed a charge like once every 2 - 4 days, i thought it was awesome. On the Incredible S it says that 62% of the battery usage has gone to display, with very little apps on the list.
The optus apps are just sitting there. Because im on Amaysim i can't exactly use them properly because you need an actual optus account. ive tried opening some of the optus apps, they're mostly just web links and theres a Mobile TV and a Music Store app i believe, but i never at all use them. so they cant be consuming any data, memory or battery or anything, right??
Im still unsure about 'rooting'. Im guessing it's android's version of the jailbreak or a godmode on the device? i might need some help on it, i know how to flash windows mobile and jailbreak iTouch devices easily.
But then again, a lot of people have bought this phone, they cant all be experiencing terrible battery life and i dont think every user would have a root on their device.
I bought it from DickSmith here in Aus, the guy there told me there's a 1 yr back to store warranty. The phone is solid and one of the best phones i've ever had, plus a good price tag on it, its a shame to let a weak battery spoil it.
im thinking of returning it, but i heard somewhere it needs a couple weeks to strengthen the battery, if that's the case then there's no point getting a new one only to wait longer, ill give it a little more time. Plus HTC is releasing 2.3.5 software for the Incredible S soon, and wikiPedia states that it's got "Improved battery efficiency". but ill still keep root in mind for when i get more use to the device.

Yes, about 40min to 1hour display on... sometimes more...I will attach a screenshot once I get throughout the whole battery.
Yes, generally good coverage and mostly 3G...I'm on Optus.
My phone has been rooted before, but now it's on stock Rom as an experiment...
I would strongly advise on rooting, it changes the phone completely.
And remove any animation (live wallpapers) those are killing the battery.
Also found one more thing. If you've got Facebook installed it refreshes every hour, i set mine to never refresh, but you can still receive notifications
But i still don't get why the battery drains soo quickly, even on standby.
edit: found one more thing.
uptime and awake time. when i turn the screen off and awake time should stop counting as the phone is locked and im not using any apps, right?? in some cases i've noticed the awake timer still counts.
example: awake time will read 1:52:39, turn the screen off at this point. go back a couple hours later it's been counting as awake the whole time, and has half battery life it did eventhough i haven't touched the device since locking it and turning off the screen.
in some cases the awake timer will not budge when i lock the phone and turn the screen off and still find the same amount of battery life remaining when i come back.

[Q] Help, please! My battery?!

Okay, so.. I have a Samsung Galaxy Exhibit II 4G.
I have it rooted with the root stock from this thread.
With that said, I've had this phone rooted for several months now. Since January or so. Over the course of that time, the phone has run without fault for months. Recently, I've had issues with my battery draining (as well as charging) far more quickly than it used to. I assumed this was an issue with the battery, because there was a slight bulge in it, so I bought a replacement battery that came yesterday. I charged it full (until the phone said it was 100%), from about 5% charge. It took the normal time (as the phone did when it was new) to charge, of just over 2 hours. It died almost completely about 2 1/2 hours later. Currently, I have my phone charging and it's at right around 90%, after just over an hour of charge from 20%. It used to take far longer to both charge, as well as die. What the Hell is going on?
Just a few notes:
This is not the result of heavy usage (for power drain). I say this because even as the phone was idle while I slept, it died on its own accord sometime throughout the night.
My bluetooth, WiFi, and GPS are almost always off, unless I'm using one of them for some purpose, and I haven't used any of those things since the new battery was installed.
There are no applications running in the background, aside from Facebook. I know this because I'm using Advanced Task Killer to kill everything, and it keeps showing Facebook as if it's opening itself for some reason. This is another issue I'm concerned with, so if anyone knows why or how to remedy this, I'd be appreciative of knowing. Otherwise I'm likely to just delete this unnecessary application.
This is not an issue where the phone is reading an incorrect charge over an extended period. It literally is dying and charging faster than normally.
When the phone is rebooted, whether it be through "Restart" (app from Google Play), via the phone Power key, or removal of the battery, the phone drops around 20% battery life when the restart is complete. The absolute reverse happens (it gains 20%) when restarting with the phone plugged into an AC charger.
Is it possible that this has something to do with the root being outdated, or maybe something updated and I'm unaware? I sincerely have no idea what's going on, as this is the first phone I've ever rooted before. I'm sorry for the long post, but I wanted to give as much information as possible.
It sounds like the battery you bought may be defective. Send it back and get a different one.
Yea sounds like you bought a defective battery. Where did you buy it from? Talk to them and see if they'll send a replacement or get another one from elsewhere

Odd Battery Behavior

I'm currently running latest Pure Nexus ROM and Despair Kernel on my n6. While they have both been working fine, I was wondering if someone could shed some light on why certain things are happening. Yesterday I dirty flashed the despair kernel because only 2 cores were online and the other 2 wouldn't start. After the reflash, my phone was able to barely use any battery. So when I got home and i decided to plug my phone in around 20% battery. I wake up this morning and I unplug my phone thinking i'll have as good battery as I did before I plugged it in. Well, it seems that's not the case. My phone seems to be using more battery than it needs as it's just sitting on my desk not in use.
How come my phone starts to drain battery like crazy after a full charge? Is it because I reflashed the kernel and that fixed things? Is it because I rebooted the device? Do I need to reboot the device daily (after a full charge)? Is anyone else experiencing this?
This behavior has been happening on full stock as well and that's why I rooted and flash a custom rom/kernel because I was hoping this behavior would be gone. I know it's probably too early to tell and I guess my phone is "settling" after the reflash, but how come the day of the reflash it runs fine?

Yesterday I dirty flashed the despair kernel because only 2 cores were online and the other 2 wouldn't start. After the reflash, my phone was able to barely use any battery. So when I got home and i decided to plug my phone in around 20% battery. I wake up this morning and I unplug my phone thinking i'll have as good battery as I did before I plugged it in. Well, it seems that's not the case. My phone seems to be using more battery than it needs as it's just sitting on my desk not in use.
How come my phone starts to drain battery like crazy after a full charge? Is it because I reflashed the kernel and that fixed things? Is it because I rebooted the device? Do I need to reboot the device daily (after a full charge)? Is anyone else experiencing this?
This behavior has been happening on full stock as well and that's why I rooted and flash a custom rom/kernel because I was hoping this behavior would be gone. I know it's probably too early to tell and I guess my phone is "settling" after the reflash, but how come the day of the reflash it runs fine?

signal quality relates heavily to battery drain. if your signal is great quality, youll probably have great battery. but if your signal is bad quality, you can watch your battery basically disappear.

I do have pretty bad in/out signal at work, but it wasn't draining my battery that bad after I did the reflash. I'm wondering if I made a change to a kernel setting that is now letting this happen.
I'll be monitoring it today. So far I'm at 86% with 42m SoT. BBS is saying that my phone has been unplugged for 4h 25m. So that is a 3.2%/h drain. My phone has been awake for 44m (screen off). This was increasing before I changed some settings for the kernel, but now seems to not be increasing as much.
