[Q] Battery level showing problem 50% to 15%.

Samsung GT-T5800. Android OS 2.1-update 1, I5800XXJH1, Kernel 2.6.29 root SE-S603 #2.
The problem:
1. Battery till 50% discharges normally - about 10-15% per day, but after 50% it immediately shows 15% and asks to connect charger and phone switches off very fast. actually no chance to mane even emergency call. No 40%, no 30%, no 20% in battery level.
2. When connect phone to charger - battery charging level immediately set to 80% or every ~10 seconds: 50%, 60%, 70%, 80%. After that phone charges about 1,5-2 hours till 100% and after about 1-2hours it asks to disconnect from the charger. Battery temperature during charging and after it: 31-33C.
After 3d 8h 40min. (~80hours using applications: Battery booster and Memory Booster, no 3G) of battery usage phone switches off.
Battery usage was:
Android system: 61%
Cell Standby: 19%
Phone Idle: 12%
Bluetooth: 4%
Voice calls: 4%
Time from 15% to 5% - 15 minutes with no using the phone. Battery's temperature 20C, Voltage: 3588mV Phone switches off. I have tried 2-3 times to switch on the phone to make battery more empty and finally switched it on and at the same time connected it to charger.
Here is the interesting charging time line after phone died and was switched on to charge it (sorry - no in seconds):
0:00 - 1% - 20C/3588mV (temperature/voltage)
0:01 - 3%
0:01 - 5%
0:01 - 15%
0:02 - 15%
0:03 - 30%
0:03 - 40%
0:04 - 30%
0:05 - 15%
0:07 - 15%
0:09 - 30%
0:12 - 40%
0:14 - 30%
0:15 - 15%
0:16 - 30% - 28C/3698mV
0:18 - 40% - 28C/3718mV
0:20 - 50% - 28C/3730mV
0:21 - 40% - 28C/3727mV
0:23 - 50% - 27C/3728mV
0:36 - 60% -
0:36 - 50% - 26C/3769mV
0:37 - 60% - 26C/3774mV
0:59 - 60% - 26C/3807mV
1:24 - 60% - 26C/3807mV
2:06 - 70%
2:07 - 80% - 26C/3906mV
2:44 - 90% - 26C/3971mV
3:18 -100% - 25C/4101mV
4:03 -100% - 22C/4184mV - Asked to disconnect the charger.
After this charge GT-I5800 (with no any software changes) stoped to show 50% to 15%, but 30% disappears fast to 15% (it means one short call).
Possible that battery issue reason is that (I think) phone was charged partly switched off and partly switched on.
Maybe there are some battery level controlling OS software bugs, I do not know.
Is it official bug or issue?
Or some guru can comment that battery level issue? I saw I was not first user having it.

should be from the firmware
it seems this happening to all

Well i also have exactly the same issue...
I have observed that when i make/recieve a call the battery voltage decreases greatly because of which the battery also decreases and after sometime the battery voltage comes back to normal but NOT the battery.
My battery also drops down from 50% to 15% or 5%.....It's really very annoying...
I think that this is a frimware issue but i am not sure..I am scared that it could be a hardware issue...
Well i have mailed Samsung also regarding this issue so that they fix this issue in the next frimware upgrade and hope others also do the same so that we have a better chance of this bug getting fixed.....!!!

And when I switch off / on the phone then it shows probably correct vallue. For an example. It shows me 15% and after restart it is 60 %. What a stupid bug - I've never have this problem with any device before. Even phones 10 years ago were able to show correct battery status. I think this problem was also with original 2.1 android firmware.

Can someone who has upgraded to froyo pl. confirm that this issue is resolved in the new firmware?

yes, in JP9 / froyo is still this battery problem. When I switch on / off the phone then it's ok. Does someone resolved this issue please ?

My issue still exists. Froyo did not help. Also I can't understand why does one time on charging battery becomes hot, another time -cold.

same for me, and today i charged my phone and after charging just put it on my table after 1h i saw that there are only 80%. Didn't see this on other firmwares

Same here. I thought it is because of my battery manager widget which I had installed, but un-installing/master clear also did not help. Looks like it is major problem. Moreover, few of the battery widgets mention that in some devices they report 1% level battery change, but in Samsung I5801, it will be 10%.

what about this issue at JPA ?
when you was installing JPA did you hard reset your phone ? (factory settings)
If yes which application do you use for restore all of the datas and settigns ?

Yes, it was done. Hard reset seems is not related, and did not help.

Same problem here...
Since built in battery meter is not accurate at all Im using custom one but problem remains.

might fix battery issue.
might work...saw it for Epic 4g and gave it a shot (as its Samsung too). Some sites say LiON do not have memory like NiCd did but somehow it worked for me. Now I stay on 100% for 5hrs or so. lasting 2 days with 45mins call time and some Wifi use. Like today charged full 100% at 9AM and now its 2230 and I have 80%.I have switched off a lot of things. See below.

Above needs to be done once only. If it doesn't work then go to service center. Remember battery has 6 months warranty only so be quick and try above on new battery.
I also run LauncherPro instead of stock. Disabled data and enable when out of AP range (only use Wifi when needed and have an AP). Background data/synch is always off unless I use market. All apps are set to never except Gmail. Use K9 Email too and ATK. Am on DDj6 FM. Have removed a lot of apps, foursquare included and run 2 screen with LauncherPro widgets only.
Settings to switch off are here.

As long as I know li ion batteries doesnt have the memory effect but they still have to be recalibrated from time to time, lets say once a month. That means dont charge the phone until it goes off and then charge to the top.
I wasnt willing to wait for 11 hours for phone to charge when I bought it and after few days I ve notice that battery last very short. After that I ve performed the full cycle (drain to the bottom - when phone turn itself off, then after few minutes turn it on, wait until it goes off - repeat few times until its completely off then charge it fully - I usually turn off the phone while charging ).
As long as I know all modern devices like phones, notebooks etc shut down before the battery is completely drained because they want to have safe margin of the battery power because of, as long as I know, when li ion batteries become completely drained then could be damaged completely so you cant recharge them again. Anyway with that "turn on then its drained" I believe that I use the battery more than normal and that phone will recalibrate to the new situation figuring that battery have more voltage than phone "expected".
Anyway with few recharging cycles like those I ve described above I can use the phone now for a 2 days with moderate usage...
That 50-15 problem still exist but 100% period last quite long and also phone can be used a long time from the moment battery reach 15% ...

Try doing it the other way round!
Keep your device on constant charge or at least as much as possible for 10 days from new and you should have now problem.
I have run tests on Lion powered devices for the past 5 years and I have never had to "calibrate" once.
My battery usage is always consistent and seemingly accurate.
And this method encourages max power from the battery.

i just flashed my I5801 with Froyo (XXJPB and then XXJPA), but having very low battery back up, can anyone advice something which can help boosting the performance of the battery? Please help.

Battery issues

Dear XDA,
Since a few weeks I began experiencing problems with the battery of my Galaxy Note 4 (SM-N910F).
It all started with the phone lasting a lot shorter per day and suddenly shutting off at around 5-8% battery left.
Today it was the worst I've ever experienced. I make a short list of what happened.
Charged to 100% overnight and taken charger out at 7:30
Went to the gym, 98% left after 1 hour idle
Bumped an extra 4% when transferring files from PC at 15:10 (from around 78 to 82%)
Watched 10 minutes of Under the Dome and did some Whatsapp
Read an article on the internet
Phone was suddenly at 28% at 19:00, shut it down for a bit
Powered on at 19:25 with only 18% left
Phone died at 19:30 with 14% left. 2h and 40 min Screen On Time. 12 hour standby.
Still able to boot but can't get past coloured Samsung logo
LED Notification stays blue and can keep booting for about 30 more times.
So basically my phone died after 2h and 40 min Screen On Time with still some charge left.
This is the worst I've had so far.
The weirdest part is that the Notification LED stays on after trying to boot it once. The only way to remove this is by taking out the battery.
When the phone was new I was able to at least get 4-5 hours Screen On Time depending on brightness.
Things I tried to solve it:
Full charge cycle and emptying it
Factory reset
Checking for unusual activity (wakelocks)
I've checked for any wakelocks but I think this might be a defect instead.
Can anyone please help me? Any advice is appreciated! Thanks in advance anyway!
Kind regards,
Daniel Collignon

Anyone?!

If you use latest version of tapatalk that's the problem
Try 4.9.5 - you can find @ apkmirror site...

Try a new battery, it can become 'weak' after a while.

Don't worry ! I have gone through this too . A log or a screenshot of BBS , System battery graph would help us . Please share it

well my phone is n910H. it lasts less than a day and it dies when it reach 30% and when i connect the charger it gives me 0%. does this means the battery is faulty or is it a software issue ?

Me too!
I have the exact problem stated in the op. I am pretty sure it must be a callibration issue because I've tried too many times the *#0228#. I've tried taking out the battery and putting it after some minutes. I've tried off-charging, on with screen off charging, on charging, fast charging, slow charging, everything and I have at most 4 hours of use, with 1 or 2SOT.
Sometimes I charge it and it stops at 70 or 75%. Today, it stopped at %50 (off-charged) and I removed the battery, waited 5 minutes, put it back on and it showed 100% (still off). Battery lasted less than 1 hour (okay, I was playing candy crush and clash of clans ).
I use my phone without the power saving mode for a snappier performance, but it's impossible that the battery lasts so little time.
Could you solve it? or just bought a new one?

Battery drain
I have same issue on my Note 4 for a last few months. And it's just getting worse.
Today it dropped from 48% to 5% and turned off.
I even took it to Samsung service and they told me that everything is OK with phone and that I have to change charging equpment.
I did that and it didn't help. It's happening again.
Help please?

My battery is crazy.

Howdy!
I think my battery is fooling me around.
Quick context:
- It's a Galaxy Tab 4, 10.1", model SM-T530.
- Android version 5.0.2.
- I received it at Chirstmas in December 2014. I barely used it until June (by that I mean maybe used it 5 times for 20 minutes). The point I'm making: I did not overwhelm or overuse it.
The problem:
I've just opened my eyes and realised some oddities... And since yesterday, I'm "actively investigating" my battery, reading a lot and "gathering data".
First thing, battery strangely draining:
Today when I switched on my Tablet, it was a 65%. I used it from 12:51 to 12:59 and it was then at 52%. I was just playing a game called "Final Fantasy Record Keeper" which does not seem to be too heavy (regarding the graphics). I put the Tablet to sleep by pressing the power button as usual.
Then I had to leave, 30 minutes after, I'm at my desk, I take out the Tablet and it's now at 42%. The tablet was in sleep mode all the time (I have a password so it wasn't possible to switch on and stay on).
I play some more and decide to use a stop watch. The battery drained from 42% to 15% really quickly, with on average around 30 seconds between each percent.
I put the Tablet to sleep again.
A couple of minutes after, I check and it's at 11%.
It takes me 30 seconds to get the cable and plug the charger. Before I plug the Tablet to the charger, I can see the battery percentage plummeting 9%... 5%... 4%... 3%... In a couple of seconds...
I plug the Tablet in.
3% to 5% in a glimpse, 8%, 9%...
Second thing, battery strangely charging:
After 1h09min, it's at 66%
After 1h44min, it's at 72%
After 2h15min, it's at 78%
After 2h46min, it's at 81%
After 3h20min, it's at 84%
After 3h39min, it's at 87%
After 4h09min, it's at 90%
After 4h21min, it's at 92%
After 5h10min, it's at 94%
After 5h18min, it's at 100%
As I don't use my Tablet often, just for hobbies, I generally just put to charge overnight and I never really checked the charging speed.
This is the first "set of data" I can provide, I will definitely look cautiously into that in the following days, hopefully under some insight from you.
Note:
I was all day with Wifi on. Even when it was charging. Everything else is off. And when I use it, the brightness of the screen is always on the lowest possible level.
Thank you very much for your first diagnosis!
Have a good day/night,

I also have that tablet but the 530nu variant and i have similar issues and even weirder i just shut it off as it was at 5% plugged it in and it said 0% charger on the powered down battery screen. Turned it back on not 2 minutes later and magically it was at 93%. Just to summarize it went from 0-93% in ,literally , 2 minutes of charging and while writting this and a few othet things, about 10 minutes since powered on its only dropped one percent. How do i access the system battery files? I am rooted so i can get into any file i want.

I have SM-335 and I have been trying to charge it for the last two days and all what I managed to achieve is 56% I have not been using it, mostly trying to get it fully charged. I noticed when checking the battery usage that WiFi was draining the battery, even when switched off to charge!!!! The other functions, like mobile network signal is constant and off when the tablet is off but WiFi bar is solid, even when the device was off. Charging is intermittent too although the cable was connected most of the time.... Next step I try is hard reset but this can't be the only solution

I had that problem on my t535. From 100 to 0 in 2-3 hours. Then when i turn it on after some time, it shows 1% but tablet works for about 5 hours on that 1%, or if i connect charger without turning on it shows 0% but when i turn tablet on it shows about 90%. I asked Samsung for new device, and i got it. Now is different story, my 6800mah battery charges in about 3:40-4 hours, and lasts about 9-10 hours(screen on time). I think thats hardware problem, because they wouldnt gave me new device if it was software problem.

Moto G4 battery dies extremely fast

Yesterday, my battery was running perfectly fine. Today, the battery goes for about 10 minutes on screen time. Getting it charged from 10% to 100% is very quick, maybe takes about 10 minutes. But going from 100%, it can discharge at about 5% per minute, regardless if im using it or not. When I was at 70%, i tried to restart my phone to see if it would fix it, but when It was going to turn back on, i was greeted with the low battery sign, signaling that the phone wasn't able to turn on. 70% = No Battery? Battery drains by 2% per minute when screen is off.
I'm running Lineage OS 14.1 official rom with magisk. Please help.
GSam Battery Monitor Says that 60% of battery is consumed by "Kernel (Android OS)"
Many times i have watched my battery go down multiple percent in a matter of a second its really scary

Your phone needs to re calibrate the battery. This is probably the bit I like the least about these phones. Near as I can tell the best method is to let it drain till dead - then plug in with your charger and leave for several hours. Power on while phone is still plugged in - let it continue charging another hour.
Use normally. You may need to repeat this a few times.

I've done that about 4 times. It didn't really make a difference... then I used a battery callibration app from the play store which didn't even require a full battery drain or charge and it worked very well... weird.

Battery regarding help!!

When I charge my phone till a % for example 54% and then I disconnect the charger and use the phone, the phone's battery indicator shows 54% for 20-25 minutes and then it will go to 53,52,.... and so on. Tried calibrating but it can't fix.
I am on Stock ROM 8.1.0 and also if my battery is at 36% and I use it for 5-6 minutes and I think that now it should show 35% but it doesn't show but when I press lock button, then the battery indicator shows 35% immediately. It means that battery % updates more quickly by press lock button rather than while normal usage. I don't know whats the actual problem. Battery is fine, it gives 5-6hrs SOT. Please provide me a solution. ?
