How can you troubleshoot certain parts of your phone?

Hi All,
So recently I have been having problems with my battery life. It's not lasting as long as it should. However, I do not know whether or not its my data cable, the device that plugs into the wall, my battery, or the charging port in my phone.
I got my phone from best buy, but it was more than 30 days ago, and I have no insurance on it, so I cannot get a replacement without sending it away for at least $100.
Any tips?

Well what battery life are you getting? Get into the Phone settings and then battery settings and post a snapshot of the graph here. Additionally you can also install Batterystat it will give you a full analysis of what's using up your battery power.

I think I may have narrowed it down to the battery itself? I have some battery apps that tell me the health is "good," but what does that really mean? My charging cable is iffy, because sometimes it works perfectly, charging to 100 just fine. However, other times it charges 20 percent in 9 hours. When I used my friend's Note II charger, it worked perfectly every-time. But the fact of the matter is, when my phone does charge to 100 from my cable, I still get not the best battery life, which leads me to believe it's my battery's fault. I am going to test out charging my phone to 100% with my friend's cable tonight, and see what happens tomorrow. I will also get batterystat and report back.
Also, this may be important. When I first got my phone, battery life was AMAZING, really quite astounding. It's just kind of dropped down, like a slope. Not a sudden, dramatic drop, but incrementally.
As for the battery info below, here is what went on today. I unplugged my phone from 100% at around 7am. It is now 6pm. Today, my phone was barely used, just sitting in my pocket with wi-fi on. When I did use it, I sent two very quick emails, played scramble with friends for about 45 minutes total, took a few photos, listened to music from the music player for about 15 minutes, and that is really all I did. I feel that my percentage should be much higher than what it is listed as.

Here's mine as you can see I'm getting almost twice your battery life. I have a few apps that i use everyday which are basically whatsapp, xda, chrome. I don't have many apps that would wake the phone constantly and if there is then I disable them from starting up when the phone is not in use. The best tool you can use for something like this would be rom toolbox pro. It's multiple system tools in one and it works great. I'm currently on Omega V10 with perseus kernel. Also I don't connect to wifi much and network here is weak and on 2G but even though I still get this battery life. In areas with good signal I get more battery life. Also I've dropped my phone twice with impact points on the corner, and just minor scuffs but that didn't effect the phones performance or battery life so I doubt it has affected yours.

Also I've overclocked, my processor to 1.8ghz and undervolted between - 50 and -100. So i get minimal power wastage from heat build up. Also you can set a black wall paper with a dark theme.

Unfortunately, I am not rooted, and haven't planned on doing so ever. Is there anything else I can do to fix my problem? I did download batterystats, and am waiting a few days though to see what it tells me.
Also, I used a different charger just to see what would happen today, and even though its been off the charger for 2 hours, it's already down to 94 percent. So I am thinking that there is either something wrong with the battery, the charging port, or could there be a bug in the phone's software?
I am thinking of getting a new battery, and seeing if that fixes my problem. I'm just so irritated because battery life used to be amazing, and I don't know what happened.

Maybe try a factory reset. Maybe something else has been using your battery.

That's what I was thinking. I will probably do that and report back, before going out and buying a battery or something. Is it possible that, although not reported in the battery info, that an app could be rogue or something or taking up battery? I don't want to do a factory reset and redownload a bad app.

Update: I tried a factory reset. It seems to either be worse or just the same. It's been an hour and has dropped to 97 percent, but I have made a couple of phone calls. But compared to before I did a factory reset, it dropped to 96 percent in two hours while not doing anything.

Keep your phone on charging over night.
Then let it drain to zero no matter what.
Do this 3 to 4 times and then
Leave it for charging overnight.
Then while it is already charging use battery calibration.

Quick Update:
I did another factory reset after I said the initial one didn't help. It looks like it may have helped, although I still have not gotten the battery life I used to have.
I found an application here called betterybatterystats, and have downloaded that. I will use my phone throughout today, and will post sceenshots.
If need be, I will take your advice about charging and draining and charging, and then do the battery calibration.

Here are my most reset battery stats. Screenshots are from the battery setting area, and betterbatterystats
Maybe I am just being paranoid and nothing is wrong? I can't make any sense out of these readings, but I hope someone else can.

first of all change you cable if you are having that kind of issues. Mine in my galaxy ace was having that problem, it was like connect/disconnect without any reason and it didnt charged my phone at all. I noticed it when it was too late, the continous on/off kill my battery. When I say kill i mean it just lasts 15 min in 3g with screen on and it happened to me in 2 official batteries.
good luck!

Did I get a lemon battery?

I recently got a Note 8 (for the pen) after having a Blackberry Playbook. The Note 8 charges fine, but if I put it to sleep overnight (with a full or nearly full charge, I find a low battery notice in the morning, or it does nothing unless plugged in. The Playbook will go down by maybe 10% overnight. I used the app manager to turn off all the applications I can see. Samsung support chat had me reset the device to factory settings, but the battery is still not sleeping correctly--or is it?
Since the playbook is heavier, I assume it has a heftier battery. Maybe you simply must power down the Note 8 at night? I like the device, but if I got a lemon I had better return it now.
What is the normal battery behavior on this thing? Thanks for any help. (BTW, I am a total android newbie and not looking forward to spending yet more hours working on this.

If you look in the battery option in the settings menu, it will give you a breakdown of the battery usage and should help you identify what the main culprets were in eating up your battery. My guess it would be having all the connections (GPS, wifi, etc on while the screen is off). It could be something else, either way that should help you narrow down what the issue is. Click on the graph to get a view on the hardware usage.

take it back; the battery shouldnt go down more than a % or 2 every hour when idling, so you got a dud..

hi
(i stated this in another thread while back),
i am on stock rom,not rooted and leaving Note8,in standby, overnight i get +_ 1% drainage for plus9/11...12 hrs..
i ran n test to see my battery drainage, and did 25 hrs on 6 % ( from 100% down to 94 %)
in this period i connected to web,twitter update weather update,google play update ,otherwise i left it to see results ..see screenshot
i would say its a 3 rd party app or otherwise you did not" tweak" ...3g off ,location ,etc.etc it right
My battery drain is excellent.i have had Note 8 for a couple months and also have the note 2
the note 8 gives better battery service( slightly ) but better ..in my case..
good luck

This. Don't even waste your time trying to resolve the problem. You definitely got a lemon.

Thanks--now store or Samsung?
Thanks to everyone for the replies. I just did a different kind of reset with Samsung--holding down buttons rather than going into settings. We will see. But if the problem persists, am I better of returning to Best Buy (I missed their fifteen day return window by a day or so) or using the service request directly with Samsung? (The store involves a bit of a drive.)

Update on battery
I just wanted to post a quick update. The hard reset (holding down the power and volume up buttons together) seems to have done the trick. At 1:30 today my battery read 83% and I have had it in sleep mode for 5 hours now and it is reading at 82%. Unless it is just that the meter is wrong, the Samsung Support Chat process SEEMS to have worked. I will try tonight and make double sure.
Once again, thanks to all who replied. The information really helped.

If you got a lemon, I joint to make a big lemonade!
I have a 5120 LTE.
After a full charge it doesn't last for half a day.
I paid attention tweaking everything: from LTE to 3g, saving energy mode, screen light, wifi on-off, gps etc.
Now the point is: I wanted this tablet to do a lot of things and it seems I can't really do anything.
And yes I already have a hard reset.
It's rooted so the guarantee is spoiled.
I hope 4.2.2 release will help me somehow.
Anyone suggesting a good tutorial to change the battery?

Unusually bad battery - wifi model

I'm hoping someone can help me figure out what's causing the unusually fast battery drain on my device. I'm down to 28% in 3 and a half hours, with wifi off, gps and bluetooth off, sync off, power saving on, 3 hr use of screen at 50% (using Lecture Notes and S Pen during that whole time). This is not normal, even for the Note 8 which I know doesn't have great battery life.
I could find no setting that shows what apps are using the battery like I can see on stock 4.3 Nexus devices. I also have the screen freeze issue so this could be all related to a misbehaving app. Any suggestions how to track it down?

That is definitely not normal. It was charged all night the previous night. I'm going to check the links posted above (thank you!), I should be able to figure out what's wrong with some work, it's just really bad timing for me, work is too busy right now to spare much time for anything else.

You know, I've got the exact same behavior on mine, but I've noticed that it'll then spend an hour to an hour and a half at 1% before shutting off. Maybe a calibration error? Does yours do the same? On my Galaxy Tab 10.1 (first generation), the proper way to calibrate the fuel chip was to charge it up to full, let it rest for an hour, then discharge about 60% or more, let it rest for 5 hours, then charge it back up to full, as those are the conditions in which the hardware chip would take the voltage readings. I wonder if the Note 8.0 has the same sort of thing?
Edit: Here's the proper fuel chip calibration procedure for the 10.1 first gen:

Interesting. I also have the first generation of the Galaxy Tab 10.1, and I never had to calibrate it. I'll have to try this on the Note 8. (The Galaxy Tab battery is still surprisingly good).
I think cycling it may help. I had a blackberry battery that could not hold enough juice to be on stand by for 8 hours. But since it was a company phone and our IT group took 3 months to get me a new battery, I kept charging it every time it died and kept it plugged in as much as possible, and by some miracle, by the time I got the new battery, the old one fixed itself. Now I can no longer tell which was the old and which was the new battery. I have no idea how or why, but it seems there are ways to bring back batteries or perhaps it was also only a calibration issue. I don't know if it's cycling, or charging it for an unusually long time, but I guess both are worth a try.

Cool. Let me know if it works. I'm going to try it too (screwed up the first time as I wasn't keeping tabs on discharge voltage; now I'm going to try to get it down to as close to 3.4v before charging it up again) and see if it helps. Of course, it's all for naught if the Note 8.0 has a different fuel chip, but I figure the last resort will be to crack this thing open and disconnect the battery for 10 minutes and hope that resets something.
Also, I too have a 10.1 and luckily it didn't have battery issues either. Still a rock solid tab, although I would love to upgrade it to a Note 10.1. I just don't think it would sell for much these days, which is why I haven't.

I wanna share my trial of battery calibration that really make a significant different at least till now .. I used to make calibration by discharge / charge cycles, but this time i add an official instruction of Apple:
- discharge the battery by ur normal usage till 1% then let the device play an HD movie till it shut down (that may take some time as it for me takes 4 hours!!) then turn it on to make sure the battery read 0% (my previous calibration the battery always shut down at 1% and I never see that 0% as I was discharging it vigorously) after making sure it is 0% it will turn off by itself anyway.
- now leave ur device turned off for extended time (about 5 hours or more is better according to apple "u could let it while u r sleeping")
- after that turn the device on and plug it in as it is on
- left it charges as it likes (for my trial it takes 7 hours and didn't say charged!! but I had to unplug it as I had to leave the work!)
till now my battery is really significantly improved, hoping to continue like that and I will keep u updated
Hope that helps :good:

[Q] Rapid Battery Loss & Rebooting Restores Battery?

So, my battery is wack... and I think it's only been acting like this since I went to a KK ROM? Maybe? Feels like it...
I've had this tablet since it was released last fall, and this behavior is very recent.
Anyways, it dies FAST. Like nose dives in a matter of 5-15 minutes. What's even weirder, is that sometimes, if I power cycle the device, it'll jump up by 30-60%. But then just dies again in another 5-15 minutes.
And there's a screenshot after I just power-cycled.
It jumped from 11% to 71%!!
Crazy!
I've also tried letting it get to 5% then charging it to 100%, done that twice. No luck. I don't know if this is related, but if I power it completely off, and plug it in, it turns on... kinda weird. My Note 3 doesn't do that, it just stays off and shows the battery charge indicator.

Hi, I have similar problem and I am with 4.3 android. I have battery loss when I play games. It drops to 2-3% really fast and after reboot it goes up to 35-40%. Once I fully depleted my battery and charge it. This time there were no battery lost. After the second charging problem persists.
If you manage to fixed it please tell us how.

I have a similar problem with my p600. the tablet is new, got it since a month or less.
at first i was amazed of the battery life i use it a lot for work writing documents and sheets on excel, battery used to perfom quite well giving me more than 5 hours of screen on, but recently the battery starts to drop very fast, now i can barely get around 2 hours of screen on.
i've already done 2 cycles of full discharge and then charge it completely with the tablet turned off. but the problem stills.
also sometimes when i reboot the tablet the battery goes from i.e 20% to 40% after the reboot.
im still looking for a fix or solution, today i found a new official firmware for my model (4.4 firmware for telcel mexico). going to wait until the tablet is fully charged and then flash the new firmware. I dont know if its going to help but i got nothing to lose.
by the way, sending it to semsung is not an option because of knox 0x1

Well unfortunately this has not worked....battery is still tanking. last night i played plague for 30 minutes....in 30 mins battery went from 90% to 25%. I think i will try reflashing KitKat....maybe my original update was screwy. If that does not fix it then I guess I will have to call Sammy.

Man i ha e exactly the same problem. I calibrated it some months ago and it seemed to work fine. Now the problem is back.... Dont know what to do... I have tried several apps, though i read google doesn't recomend to use any app to fix the battery... we really need help here

Sorry to bump this, has anyone found a solution yet.
I've replaced the battery 3 times in about 9 months, but had this issue about a yr, was sent back to Samsung who changed the battery and supposedly updated the fw 4.4.2, I have since replaced the battery another 3 times every 3 months, each time either factory resetting or flashing a new rom, currently on official Smp600 5.1.1 BTU rom, today my battery was on 47%, I plugged in charger and was watching/streaming a movie on it, about 80 minutes later the tablet shut off, which was odd it's never powered off while on charge, powered it back on and battery said 19%, my previous issues has been the same as others, it can be on 100%, play a game, or stream a movie,or watch youtube etc and it will nosedive dramatically 20/30% at a time, sometimes within 10 mins it's gone from 100% to less than 30%, it's clear there's some sort of issue if others have it, I was wondering if a thread should be made to list ppl with this issue to see how many there are and go from there.

I've been having the same issue for some time now. Calibrating the battery does help, I don't experience the problem nearly as much after calibrating it. But it'll still nosedive on occasion, maybe once a week. This is the app I use to calibrate it https://play.google.com/store/apps/details?id=com.nema.batterycalibration

Battery Reducing Quickly?

Hello everyone, new to the forum since I just picked up my note 10+ and thiught this forum seemed more knowledgeable than others for battery issues or issues in general. I dont really know if it's an issue but I'm curious of how others people batteries are acting for their note 10+'s. Mine died a few hours ago and once it hit 100% I removed the charger and didn't use it for just over an hour and I noticed my battery went down to 2%. I have my always on screen on of course, most of the apps were dead and I did optimize the battery in the settings while my phone was charging then stopped using it until it charged fully. So I had no apps open and I had a version of battery saving on. I did medium but left the higher res screen on including the cpu at 100%. Would this cause my battery to go down 2% in an hour without any use?
For a side question, is there a better way to get the most out of your battery? I always thought it was let it die everyone inna while but I read recently charging it to 80 then letting it down to 60 and back up to 80 and repeat is the best? If that's true, how do you keep that up and how long will you need to keep that before normal chargers?
Thanks. Hope someone can help

If it went down 2% in an hour, that's 50 hours of standby plus always on display. That's crazy good.

Best way to go is using normal charge an never let the battery drop below 20% forget about trying to maintain certain range (60-80), it will just drive you crazy

If it went down 2% in an hour, that's 50 hours of standby plus always on display. That's crazy good.

If I put my iPad mini to sleep at 100%, I wake up the next morning with 100%. Maybe 99. But usually 100.
That's not the norm, and it's not perfect apples to apples, but it is possible.
Also, 2 days of standby with zero use is not unusual, but definitely not "crazy good".

It went down TO 2% not down 2%.

That's not what he said. Read it again.
"Would this cause my battery to go down 2% in an hour without any use? "

Wow that is unusual. Do a search for "sleeping apps" in setting and add all the apps you don't need running in the back ground. Also in device care > battery you can see what app is using your battery.

So besides that little fight you had with the other forum member (lol) I appreciate your comment. But there seems to be back and forth, one other person says its good, another says its not. (the one I quoted below). Just seems weird to me that with no open or running apps and just the always on display running that it went down in an hour in 2%. Searching around, people saying losing 1% In an hour with the same set up, no running apps with AOD is bad. I kind of agree since its not truly in use. But unfortunately I cannot find any battery standby tests from Samsung or anyone else to confirm it.

I agree with you more honestly that it shouldn't be going down that fast in an hour with just the AOD running. I didn't have any apps running once it 100%, I was on it while charing it to around 50% but then once I knew I was putting it down for a while I ran the optimization and had the phone kill all the apps. When I saw it go down the 2% I did check out the apps using the battery and the AOD was the only thing listed. Maybe I didn't charge to a full 100%? even though it said 100%... Ill check it out tomorrow once I charge it fully again, today I was charging it up and down most of the day sadly. I try and keep most apps from not running in the background, some I do need though like for my IoT devices needing to know my location, I have yet to change that to just using LTE as my location GPS, but that was not on last night all. Ill try out the sleeping apps though, I didn't know there was a setting for that. Thanks again

AOD typically consumes 1%~2% in my past note devices(7,8,9)

Hello everyone, new to the forum since I just picked up my note 10+ and thiught this forum seemed more knowledgeable than others for battery issues or issues in general. I dont really know if it's an issue but I'm curious of how others people batteries are acting for their note 10+'s. Mine died a few hours ago and once it hit 100% I removed the charger and didn't use it for just over an hour and I noticed my battery went down to 2%. I have my always on screen on of course, most of the apps were dead and I did optimize the battery in the settings while my phone was charging then stopped using it until it charged fully. So I had no apps open and I had a version of battery saving on. I did medium but left the higher res screen on including the cpu at 100%. Would this cause my battery to go down 2% in an hour without any use?
For a side question, is there a better way to get the most out of your battery? I always thought it was let it die everyone inna while but I read recently charging it to 80 then letting it down to 60 and back up to 80 and repeat is the best? If that's true, how do you keep that up and how long will you need to keep that before normal chargers?
Thanks. Hope someone can help

Battery optimization takes a little bit so if you just started using the phone give it a few days.
Also, package disabler or ADB can be used to turn off any major things that you are not using (i.e. Bixby or DeX).
Regarding Cell life: Yes between about 30% and 80% are the optimal percents. That doesn't mean try and always keep it there, that would just be silly and unrealistic.
However, it is important to be conscious of this. For example, don't leave your phone on the charger for days on end sitting at 100%. Don't leave your phone in a drawer or a backpack with 0% in the cells.
Cells are technically damaged (or worn would be a better word) every cycle. The most damage comes from when the voltage drops to its lowest point and its highest point. (i.e. 0% and 100%)
For example, if someone were to charge a LiPo or Li-Ion battery only between 30% - 80% for an entire year and another person with the same phone always went down to 1% and always to 100%, the latter phone would have more cell wear thus it would not hold as much power.
Once you learn of this and become conscious of this then you tend to adjust your habits. All other myths and theories about battery calibration have really not been a thing in many many generations of Android. While you can screw up battery calibration through a service menu, rarely (if at all) a battery loses calibration. Most people start seeing battery wear and think its a calibration issue and then seek ways to fix this. At that point, it cannot be achieved because there is a physical change to their battery which can only be refreshed by getting a new battery.

Reporting my battery life. I guess this is truly an all day device.

Give it a couple days to settle. The first three days, mine got pretty bad battery life. Then yesterday I got almost 10 hours of screen time after using it pretty heavy all day. Mixture of Facebook (battery hog), Internet, texting, emailing, and using the camera (also a battery hog). What finally killed the battery was me downloading, installing, and uninstalling multiple versions of GCam trying to find one that worked well enough to use. I finally found one before my phone hit 0%.

In an hour? Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use.

This is useful, thank you. Never knew not discharging device is the way to go but we all learn new things every day. I'm at 65% right now, when waking up at 6am with 95%. Wireless android auto for about an hour, plus okay-ish use. Ill make sure to charge it up to around 80% tonight.

Thanks, I think I am seeing a bit better today after having it for 4 days or so now? Ill follow the above quote about calibration and go from there.

Over 8 hours screen time is great, best I've gotten so far is 7.5 hours

I just wanted to throw my two cents in here... My battery life is pretty terrible in comparison to my S10+. Trying to find a rogue app of some sort but I just hit 1% with 12 hours off the charger. Keep in mind that is not 12 hours of use. In fact I used it for about an hour of total screen time today.

Yeah I came from an S10+ and noticed my battery on the N10+ was pretty bad in comparison.
I did restore everything from my S10+ though, not a clean install of everything.
Wonder if that may be causing issues.

Is everyone having problems on Verizon?

Quote " Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use."
Unless you put it in airplane mode, your phone will keep connected to cell tower (or wifi if you have wifi calling) otherwise you won't receive calls and messages, so there is no such thing as phone with no use, and if you have weak signal or some interference your battery usage can increase drastically even in standby because the cell radio will try to connect at full transmit power. And then you have all those programs running in the background, God knows what they're doing. As others suggested disable programs you don't use, also you can force close programs that you don't use often. When I had my older Note rooted, I optimized it so well it would run 2% down per 8 hrs overnight, but it took some effort. Biggest problem is to know what to disable without loosing functionality for stuff you need. Give it some time for people to learn more about new phone. BTW my 3 day old phone has 435 apps and services installed and most of them I have no idea what they do.
