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!

Dear all,
Recently my Note is facing a weird problem. While my son is playing a game, the battery drops 20-30% in 10 minutes. If I shut down the tablet and re-power then the battery goes to normal again.
In the battery stats I can see a huge drop during game usage and then up again on reboot.
I performed a factory reset but the same happens....
I flashed the Kit Kat via Odin.... but the same
Any ideas?
Drain the battery down to below 5% then charge it to 100 and it should be fine. It happened to me once and after a full charge after a full drain it never did it again

This is what worries me.
I drained the battery and charged it fully powered off. It did it again. I drained the battery and charged it fully powered on. It did it again.
If I'm using it for browsing, papyrus, images etc its fine. This happens only in games and when i reboot the battery percentage is ok again.
strange....

I had the exact same problem as you are describing but additionally, my overall battery life wasn't lasting as long as it should either. I ended up sending it to Samsung's repair center to get fixed. I'm not sure what they did but some other people on the forums suggested it was a motherboard issue.
So the capacity of the battery seemed just fine but the readings were crazy (dropping from 50 to 5 in minutes and then on reboot back on 50).
After 2-3 full cycles of charging nothing changed. Flashed fw nothing changed. Went to Samsung service and they just informed me that they changed the battery and now performing final checks.
Hope this will solve the issue. I'm too lucky that I am in the "6 months warranty" window for battery...
How does one go about sending it into Samsung? After getting it back, did you see a significant change?
I've been debating doing this but wasn't sure how to go about it.
I haven't got it back yet. They just called me and they said that apart from the battery, they need to change another part (the telephone operator didn't know which part) and I'm going to receive it tomorrow.
So I'll let you know once I receive it.

After trying everything (flashing different roms via odin, factory reset, full battery cycles etc) the problem never went away.
Went to Samsung service. They checked the battery and had to replace it.... within the warranty.
Same issue here. Just got an email saying its fixed. They changed the charging port and lcd. Weird that they replaced the lcd.
Well I got it back. Seems they broke the s pen function when taking it out or putting in. The tablet thinks it's always out of its slot. I guess another 2 weeks without this thing. What a pain in the ass. Times like this makes me wish I bought an ipad where I could just walk into the store and get it fixed that day.
I had the same problem. I sent it back on Monday and got it back 7 days later. They did not say what they changed, but now everything is working fine. I even got a new usb cable and a magnetic Germany flag
I sent mine in for an overheating problem and they changed the charging port and gave me a new cable. I initially also had the random drops in battery but seems to be better now.. They said bad voltage going to charging the battery or something. Still have overheating so gotta send it in again?

So guys did you get it fixed? I have exactly the same problem. I have sent it to fix at the sam service - they changed the charging port, but it didn't help anything. 1,5 years of normal usage and now I can pretty much throw it into the toilet. God damn POS!
Galaxy Note 10.1 2014 battery drops
Hello all,
Just wanted to inform you all that I have been experiencing these battery drops (yesterday from 93% to a mere 5% in a matter of minutes) for a very long time now. I am running under the latest 4.4.2 stock firmware.
Also, battery life is way below par (understatement !), where the Note sometimes drops to around or below 5% (the magic number below which the screen starts to dim pretty dramatically and there's no way to influence that)
Funny thing is that after the battery drops to below 5% or even 1 or 2%, it's still possible to use the tablet for quite a number of hours afterwards, which suggests it may be something with the logic estimating/determining the remaining battery capacity, rather than the battery itself....)
Now I've tried draining the battery and fully recharging it multiple times/ resetting the stats using free apps / revert to factory settings etc.
All to no avail unfortunately, this problem simply keeps coming back.
(By the way: Apart from the battery and battery life, the Note is an excellent device, and delivers as promised.
Please also note that charging it through the microUSB cable is also simple, stable and relatively fast, unless you compare it of course to my all new Samsung Galaxy Note 4, which has a superior fast charge mode and offers the highest possible battery-life at this moment and easily beats any other smartphone (including the usual suspects from that Cupertino-based firm of which I can't force my mind to remember the name of.....) in this price-quality and performance category )
As for warranty:
Battery is no longer under warranty, the device itself is.
As such, I will now get the battery replaced by a new Samsung OEM-battery first, and see if that resolves the issue.
If it doesn't help, I will send it in for repair for Samsung.
I will keep you all informed on the resolution and cause.
Likewise, if there's anyone that has gotten to the root cause of this issue, please let me / let us know
Some users reported some 'magic part' OTHER than the battery itself (motherboard / charging circuit or even the lcd ??) having been replaced by Samsung after sending it in for repair.
That information could be very valuable to us all in trying to get Samsung to resolve the issue, so I would really appreciate it if someone would share this info in this thread.
Hey I know that there hasn't been much activity on this particular thread, but i too have been experiencing this problem for over a year now. I sent it into samsung twice and it still never fixed the issue and by the time i was going to send it in the 3rd time it was out of warranty. I personally removed the back cover and unplugged the battery for a while and that did not help. I have tried flashing different ROMS and kernels to no avail until last week. I flashed Temasek's Unofficial Build found here http://forum.xda-developers.com/gal...t/lt03wifi-temaseks-unofficial-build-t2980604 and after 3 full power cycles i have not had a single random drop yet i even managed to go 3 days with 6 hours of screen on time which is a record for me with this device. Not sure if it will help everyone but this seems to have solved my problem and i am thrilled! Also (as embarrassing as it is) i played 2.5 hours of Clash of Clans straight without a single random drop either.
I am beginning to have the issue as well on my P605v. Has there been any progress with your battery replacement? @mroset

Hello KwestJones,
I've successfully replaced the battery in the Note 10.1 2014, and it has improved things. With a little care, this is easy to do. Just removing the battery connector is a bit typical, you need to lift it carefully and slightly to remove it.
The result is not as drastic of an improvement as I would like to have seen, but at least the sudden drops in battery capacity percentage seem to be under control now.
I am doing a video test now, and will see how it behaves and let you know.
BR,
Maarten
Very curious to hear if replacing the battery corrected this issue. I've been experiencing this same battery drop issue for 2 or 3 months and the unit is well outside of warranty. Hoping there's a simpler fix, but willing to replace the battery if that will work since the tablet itself is still a great unit.
Complete factory reset should clear the Android Coulometer's data base or learning algorithm. Just clearing options of Battery Monitor Widget for rooted devices won't help. There are some other apps, which seem to help if the charge level never reaches 100%, a related, but not identical problem.
I have an old tablet suffering from this, with a tweaked custom rom, and i didn't want to clear and setup that completely. The algorithm or database is "learning" again, and the capacity jumps have become fewer and smaller over the last months. It should depend on how long the device was used and never reset before the incident. In my case over a year.
Itvs much like my cars fuel calculator, which won't work correctly during traffic light stops. Right after starting the engine, fuel consumption can raise several liters/h, when the car don't drive, as it uses the last sampled value(every 30 meters). And you need several kilometers to drive to have these levels drop to realistic ones again. While after a long driving distance, a traffic light stop will hardly have an influence.
Hi guys -
My 8.4 has been driving me crazy for the past week. It is not rooted, running the stock Samsung image. The battery percentage seems to be wildly inaccurate. I've read through many of the battery threads here (most seem to deal with the inability to charge completely), but I have noticed some that seem to resemble my problem. The solution seems to be to pop the back off and replug the battery. I have not done that, and frankly, I don't think that's the issue here.
Symptoms: Battery appears to drain unevenly - will drop several 10's of % instantaneously during mixed use, and sometimes level off again. I haven't found any runaway processes. Bottom line, overall less then expected battery life followed by the system shutting down. HOWEVER, if I then reboot, it will boot up anywhere between about 5 and 30% remaining - and will continue to run. Sometimes it will drain quickly again, other times it will run for several more hours. Sometimes if I connect the charger after shutdown, it will immediately jump to 40% upon reboot.
Experiment: Drain battery smoothly after a full charge by looping a local video, and track battery percentage and voltage. When system automatically shuts down, reboot (it pops back to 30% or whatever) and continue. Keep rebooting and running until a reboot registers 0% and immediately shuts back down.
Result: Battery drains VERY evenly and consistently. It's only the android percentage that seems to be erratic and cause the system to shut down. I've attached a graph of what I see. The spikes represent points where I rebooted. Blue line = battery percentage (left axis), orange line = battery voltage in mV (right axis)
So given this, I'm having a hard time believing it's a battery connection issue. My uneducated guess is that unplugging the battery works for some because it forces android to recalibrate the battery meter. I've been unsuccessful in getting it to recal by charge/discharge cycles.
Does anyone have any thoughts or ideas on what I should do next? Is there a way to force a recal of the 0% point without rooting? As a side note, I find it odd that my Nexus 7 simply doesn't boot when it hits zero - just shows a battery symbol. Seems odd that the Samsung let's me constantly boot the thing.
Any thoughts would be appreciated!!
Mike

Hi! I own a tab S and some users get this problem also on the tab pro. Its something with the battery connection to the device which causes the gauge to be all wonky. Usually problems like you described need to be replaced by Samsung. If you are under warranty, then they'll replace it for free of charge. Better to be extra safe! Hope this helps!

Thanks...yeah, I saw all the comments about the battery connection. As I said in my post, I'm still struggling to believe that it's a connection issue when the battery voltage - reported through a battery widget - is very reliable and steady. It's only the percentage that's wrong. Sounds more like a software issue to me. If it was a connection issue, I'd think the battery voltage would be all over the place too.
Frankly, I'd rather not send it in if I can avoid it (no service centers local). I'd like to explore all possible other options first. Any other ideas on how to force a real recalibration?
Thanks,
Mike

When your device is fully charged, My guess is to turn your brightness up to the max and open an app that's like intense graphical games or Google earth. As long its stresses your CPU and GPU. That should make your battery drain really quick and cause random reboots because of the meter. Keep doing so till it reaches 0%. Then recharge. If that doesn't work then I don't know. I've done that many times after I flashed a custom ROM so it would calibrate. Doing that would draw all the power out hopefully

Ok...I gave up. I've tried the drain thing multiple ways. I don't want to root the thing or install a custom ROM because I won't be able to use it on my company network. I called Samsung and set up a return. What really bothers me about this is that without an explanation, it's likely to just happen again -because again, I'm still convinced it's software related.
Thanks anyway,
Mike
Sorry to hear that. Please come back when your device is returned from RMA and tell us how it's doing...

Will do Calvin - thanks. For the record, I tried one more thing before I boxed it up. I reflashed the firmware with Samsung Kies3. It all went smoothly, and I had high hopes....but shortly after logging in to start setting it up, the battery immediately dropped from 99 to 88....so no luck. I'll be shipping it out tomorrow. I'll post my findings when it returns.
Mike
Well guys - I got my GTP back earlier this week. The actually fixed it in one day and shipped it right back to me. Unfortunately, there was no explanation or description of the repair on any of the paperwork or their website - so I have no idea what they did. Regardless, it appears to be functioning normally now. I fully charged it when I got it, and then ran it down to zero through random usage throughout 2 days...and when it hit zero and shut off, that was it. It wouldn't turn on again (which is what I would expect). I charged it back up, and it's working fine again. So far, so good.
Bottom line, I guess I had some kind of a battery problem, but it appears to be working now. As I said before, I just hate problems with no explanation - it means they are likely to happen again. I guess time will tell...

All,
Last weekend, I experienced the most unusual occurrences where my Note 7 battery just drained within minutes while at least half full. I was browsing the internet on my phone waiting for a drink. I put the phone down to pick up the drink, and when I went back to the phone, I could not interact with it. I pressed on the power button for a few seconds, nothing. Went back to the car and plugged it up and there it went, it was out of power. I first thought it was weird, cause I could have sworn I had at least 40% batter left. Ok, whatever, that night it happened again. I'm pretty anal about battery power, so I will definitely notice when my battery reaches a low level especially so low that power shuts off.
Ever since the two incidents my phone has been running fine during the week. Just right now, I noticed my battery was at 39%, so I was like ok, let me plug it in and give it some juice before I leave work. I stepped away for a few seconds and come back to my phone and see it at 11%, I was like what?? I unlock my phone, and seeing it go down 10%, 9% while its being charged...I started "close all apps", still going down 8%, I go to settings, "optimize" and optimize all, nothing, 7%, finally drag down notification, close the Tidal app widget, and clear all, think what was left was Good app. 6%....keep watching the battery screen...7%...few seconds more 8%. PHewwww....
WTF was that?? Was it a rogue app that was sucking up the battery? But what triggered it? I checked GSAM battery tracker, Android System at 35% CPU usage 6h 9m, next is Kernel 11% 1h 56m, then Good 5.3% 55m..Instagram 4.9% 52min....
Its happened to me 3x within a week. GSAM is not telling me any info on what is causing this.
Any ideas?
If I were you , I would shut it down and return it .

Yes , maybe . Phone freezing and battery rapidly discharging in the actual context doesn't seem good. Be cautious...
Cheers~
Get rid of it ASAP!
When batteries discharge faster than expected they can generate heat, this heat can trigger the bad battery "explosion" we are all fearing.
This sounds like a prime situation. Shut the phone off and leave it off.
Get it replaced ASAP.
you should replace it
this is faulty battery
how long you had it so far
and how was batterg life , lagging , overheating like ?
FAULTY ALERT. do a scratch test and return it! lmao jk. just return it.
I have also had this happen where I check my battery percentage 75% then not a minute late my device is off and wont start up until I plug in a charger and then maybe 5 minutes later it show 30%. Something is really screwed up with the either these batteries or the phones themself. Worst decision ever was to not make the battery user replaceable! My Note 7 is going back once the replacements are available.

Yup...I don't believe its the battery but something in the OS. I don't really care about removable batteries, but this battery fiasco, the lag, the battery drainage we experiencing...I think I'm done guys. I'm still on the fence, but leaning towards to the Iphone 7 Plus.
I honestly think it's something in the battery. The way they're exploding and the way it randomly drains points to battery issues. Plus if it was a software issue, Samsung would have pushed an update a long time ago. It's much easier to push an update than recall every single phone. I personally think the chemistry in the battery is off, that's why we get random drains and exploding batteries. Regardless, mine is getting exchanged as soon as the replacements are available. Btw, mine has been doing the same thing for the past week, so I know about having 50% or more of battery and it going completely dead. That's can't be because of the software. The phone would get hot if a rogue app was draining that fast. Not to mention I've never seen a rogue app drain a battery instantly...

This could also be the electronics not accurately determining the batteries voltage. In turn, allowing the battery to charge well above what's safe (3.7v battery charged by a 5v charger)- and if there's one thing you don't do to lithium batteries it's overcharge them.

If the battery is not defective and it's the Power Management Circuit which is problematic, then the risk will even be more disturbing than the idea of having a defective battery. Anyone knows whether the Exynos variant is also using Qualcomm power management IC?
This is the extent of what Samsung is saying:
Based on our investigation, we learned that there was an issue with the battery cell. An overheating of the battery cell occurred when the anode-to-cathode came into contact which is a very rare manufacturing process error."
The leads shorting doesn't represent a problem with the cell - overheating/exploding would be normal in this situation.

Hi all,
So i got a HTC 10 UAE edition from a guy two days before. He was selling it at a reasonable price and i bought it from him.
The battery was draining quite fast and i thought it might be a software issue and i installed venom rom, but problem still existed, so i turned back to stock 2.41.401.41 (Which was very hard though) .
Still the battery is draining so fast. The charger came with the phone( Quick charger ) was also not working and now i'm facing the phone's battery is draining so fast. I'm very confused whether that guy have cheated me or not. If this is a hardware issue i think i have to contact that guy soon.
adb battery stat gave me 2580mah full charge capacity and here, i'm attaching the GSAM battery logs.
Please help me on this
Thanks
Edit: Since the original charger isnt working, im using a oppo 5v- 1A charger, is dat matters on battery drain?
Mine was doing the same as yours, quick charge also stopped working. I changed the cable and it solved it for a few weeks, but the drain started again and quick charge stopped again. Tried ruu etc but no luck. I've sent mine in for repair under warranty and should get it back Monday. My guess is either the charging port is faulty or motherboard but will find out next week.
I was having the exact same problem. I downloaded an app called Lspeed (It's also on the playstore) and did some tweaking in that app as well as used the Enable doze for GMS Magisk Module and now my kernel and android system are on par with each other as far as battery drain goes. Not sure why there are only a handful of people that experience this problem but i'll edit this post with screens of my lspeed config if you want to give that a go!
Edit: Config uploaded. Some of those options are personal preference but take a look around and test it out. What you'll most likely want is to enable the light doze optimization and disable the debugging. That will most likely help in your situation.
Very strange, I'm experiencing this issue too, always receive around 2-3hrs of screen on with very high kernel use during standby. Tried flashing Leedroid, Element X to no avail.

I'm currently running on pure stock. Will try this method soon. How was your battery standby before doing the tweak ?
Have you tried wiping cache? Mine drains fast depending on the load, which is usually pretty heavy daily. Plus, I don't dim my screen much. Never knew the advice command for battery. I gotta try that.

Okay, so I got fed up with the battery life I've been getting and have looked more into it, I've managed to reclaim a lot of the longevity I had before updating to Nougat without hampering UI fluidity. For reference, I'm using Leedroid 3.9 with Element X v1.08 and was getting around 2hrs screen on, android system and kernel had the highest usage under GSam.
bilibox has the right idea, my idle drain was very high, L speed and Greenify both have options to enable a more aggressive Doze which worked pretty well, I lose ~10% battery overnight vs a shocking 20-30% before. I still felt battery drain was too high when active, I combined ivicask's PNP mod (balanced) with some little governor tweaks in EX Kernel manager, basically, I'm using interactive on the little cluster and elementx governor on the big cluster (which tends to be slightly more conservative in my uses). I also set min performance to 0% and downclocked the big cluster to 2Ghz, I'm focusing on these cores since they were draining a lot of power in my case.
It's not a super extensive list of tweaks nor something we haven't seen before, but I manage around 3.5hrs of screen on now which gets me through the day. Before I would have to top up around early afternoon, the phone is also really smooth and I'm happy with how everything is running. I hope this helps some people out!

Still its bad that a 3000mah battery with a smaller screen compared to other flagships giving a very low battery backup just because of software bug. From reviews, i can see that MM is giving fine SoT as well as standby. One thing i really cant is the standby. I cant even go out for a day trip. The battery will die in just 10-12hrs even on standby.

That's unfortunate to hear, my battery life is pretty much in line with my friend's S7 now, newer devices can get away with larger displays because the 835 is a bit more efficient.

I restore my phone and did all updates again. My battery still seems to drain very quick .in an hour with some navigation, and little screen use It went from 20% to 1 percent.
I've taken excellent care of my HTC. Before this, I had HTC 8 and loved it, until right at the 2-year mark, a small area of the screen stopped working.
This is the second time I` experience this, and sadly there won't be a third., especially after new HTC removed the headphone jack like the iPhone ... RIP HTC
Well to be honest the past couple days were to weird to me usually i get 5 - 6 SOA over 13 hours
now i get 3:30 - 4 SOA over 13 hours, same usage, and i have noticed that google service consume most of the power, i have installed doze program and kept my eye on GSM battery Monitor, after all the google service kept the kernal wake up for a long time, and keep running the hardware on the full abilities
I unistalled Gsam battery monitor and kernel usage is back to normal...

I have uninstalled ForceDoze and Gsam Bettery this morning but still feeling that there is something wrong, i might do some battery calibration on my free time, because i charge my phone only for 90% and it did not get lower than 20% i feel like i am losing the battery capacity
Was having the same issue, and had been searching for weeks to try and solve this. Tried rooting, factory resets, ROMs, everything.
For me the issue was Google Sync, in particular Contacts and People syncing. I disabled those and everything is back to normal. There was a program called Google Contacts Sync (Apps > Show System > Google Contacts Sync). I cleared the data on that, and then went into Accounts and Sync and turned everything off. That fixed the battery drain. I have tried turning back on Gmail, Keep and a few others and still have great battery.
I have the same issue and I don't know how to fix it. Please help
