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.
Hi,
probably someone else have just post this kind of question, but i don't find it , really, sorry
i have just install 2_HD2 Pdaimatejam Rom Wp7.8 OS Is the last version, i think...
the problem is that, the battery life is less then 4 hours . how can i do ? it's normal ?
thanks for replay
look my signature
I would like to add: after flashing ROM fully discharge your battery and then recharge it. After that go to registry editor on your phone and go to
Code:
[B]HKLM/system/state/batteryux/MainIntervalIndex[/B]
and change the value from 6 (or any value it shows there) to 20...now press OK! You wil see that the battery level on top has been changed!
Now again edit it and go from 20 to 80 and press OK...
RESTART YOUR PHONE AND THEN CHARGE IT!
This helps me a lot. I used my phone about 37 hrs with calls, little use of BT and WiFi.
and then you don't need to do
- when battery drop to 50% (for example), restart phone... battery status be refreshed and show around 20% more battery level.... sometimes i restart 3-4 times phone before need to charge it....

where exactly did you look?
how about google 'hd2 windows 7 battery'
there are +3000000 hits and the first page has several links to xda here and also youtube videos to watch
this is a common problem for all these windows 7 roms.
the registry tips posted in below and also try the 'camera trick' which works for me

well, the main trick is to discharge to 0 and than re-charge battery. My battery drain today is about 1% per hour. Battery consumption is very individually.
P.S. I installed hardware radio 2.12 and software radio 5.51. This cimbination is much better for me.
Hello,
i don't want to start new thread about my problem, so i pin here.
When i was thinking about to buy HD2 i didn't realize what i am going into, but now i have to continue.
Well everything is fine except damn powerdrain. It is normal to have on high usage 300-500 mA drain? Well i understand this usage when playing for example gta3 on nativeSD android, but seriously...?
Normal work drains my battery on android in 4 hours (NativeSD nexusHD2 - Wifi, exploring web, youtube, facebook etc) with about 150-300mA usage. Well i have to admit that currentwidget cannot show drain properly, but what it shows look really insane.
Also i found on WP7 more outrageous drain. I plugged in charger to HD2 and launched sims3. The battery was at 5%, but gaming made my battery dead. I had to buy external battery charger to apply some power, because battery was too weak to hang in boot time.
My primary questions:
1. Is this high drain normal?
2. Is 80mA charging power normal (using HTC charger)?
3. If i flash android to nand, will power consumpion on high usage be less?
My Son's Nexus 10 had served its purpose. But Started to die at Random percent, Mostly above 50%.. So Got a new Tablet for him. But Did not want to throw away this Gem of a Tablet.
After weeks of Trial and Error finally found a solution Thanks to input from a Redditor.
Issue/Problem: Dies at Random % showing battery %0 and Shutdown. But In Recovery with Full Brightness it does not Die for hours.. (as later found out.. Recovery does not need much CPU power)
So What did I try:
1. Changed Rom's (All the way from Base Google Images to Oreo) >> Did NOT fix the Problem
2. Clearing battery stats.. etc. ( incl completely discharge and Charge and all those cycles usually we do to calibrate the battery) >> Did NOT Fix the Problem
2. Ordered a New Battery - (Samsung Model From Ebay - I guess it was used or who knows ) >> Did NOT fix the Problem
3. Changed Multiple chargers (Wall Adapters/ Cable from multiple brands which i have at home.. LG, Samsung etc etc) >> Did NOT Fix the Problem
Solution/ What Fixed:
Thanks to redditor.. Who mentioned about CPU power consumption.. And Old Mother board might not be providing enough Power to CPU. (As this tablet is Old.. It was just an Hobby to make it work and Did not want to spend more money on MotherBoard)
By this time I was on Marshmallow Linage OS Rom.. (As Everything works), Gave Root access to one of the CPU app's and Did this..(See Below) Enabled on Boot to keep the same settings.
Setting the CPU max to 1200MHz and Min to 200 it WORKED! I tried every damn thing before. For some reason... this idea did not strike my brain. So its the Power consumption from CPU.
EDIT 1: after some more testing You can go upto MAX 1600MHz (Your mileage may vary)
Finally Battery drained till zero without shutting down.
LET ME KNOW IF THIS FIXED YOUR TABLET TOO.. If you have the same issue as mine. (I Know many had this issue like mine.. but none had solution) Hope this helps.

Unfortunately at the moment I don't solved the problem, even if I set the cpu min to 200 and max to 1200.
I've installed a new ROM, deleted the cache and still the problem persists. I will do other tests trying to recalibrate the battery.

Humm... Anyway @1600 mine died at 30% .. So made it 1500 and past below 18% and Still running. So I guess 1500 is max I can go
Also Before coming this conclusion: I did the fowling
Charge 100%
Delete Batterystats.bin
Run this command from adb "adb shell dumpsys batterystats --reset"
And then Changed the CPU max (Please NOTE , Select "On Boot" to keep the same parameters). Once u change the CPU settings .. Reboot and see .. if its keeping the same settings.
Many thanks. I tried all of the the things you tried and setting the cpu max frequency is the only thing that worked.
I could get away with seeing it to 1600.
Deleting batterystats.bin does nothing https://www.xda-developers.com/goog...-battery-stats-does-not-improve-battery-life/

Streetmart you absolute legend. I'd never thought I'd see the day my Nexus 10 would drain down to zero again. I tried 1600, then 1500, to no avail; then I said screw it I'll just go down to 1200 (with little hope of it working).
It feels so weird to actually have an internet “solution” work. I'm super happy. I didn't want to buy another tablet. I love this one and it worka perfect for what I use it for.
Thank you! :good::highfive:
OMG! thank you for this thread! i was just posting to look for a replacement for my 10... i hope this fixes it BTW.. what's the normal max cpu speed? I REALLY don't want to replace it as the new dropbox 3 device thing really screws me..

I think the normal is 1700MHz. It's what the program showed before I changed it. All the best! Keep us updated.

What a difference... i installed that a few days ago, and i haven't used my N10 much but on standby it's still at 99% usually it would be WAY lower.. i think that program did more than just lower the max cpu a little.. don't care though. the N10 lives on!!
If you still have this issue, I have been updating the kernel and also found some of the power control settings needed tweaked. Disabling "opportunistic sleep" "logging time spent in suspend" and enabling "advanced power controls" seems to do the trick. had an issue where the device would shut off if battery level reached 20%. Haven't had it happen again yet.

I'm currently running at 1600 with this guy modified kernel and wow, besides no more suddenly shutdowns it runs very smoothly, it reminds me the pre-marshmallow age of this tablet.

I have replace the battery of my N10 because of low capacity.
Now it charge from 0% to 52% then it goes to 100%. On discharge it goes from 100% to 46% then shutdown and battery shows 0%. Percentage is the same in TWRP.
Since replacement of battery it have aroud 10 charge/discharge cycles without any changes.
Any solution for that?

I have to agree on, that the N10 chipset/cpu/powersupply has degraded somewhat & as the battery voltage gets lower during discharge, it can not supply stable power any longer :crying:
If i reduce the CPU speed from 1700MHz to 1200MHz I get to go down to 20% instead the N10 shutting down abruptly at just 30%
I do have a spare battery in the fridge for later on. Once I open up the N10, I'll see if there is a capacitor or two, that could replaced in the power supply area to possibly fix the issue.
Note:
1. On second full charge since lowering the CPU to 1200MHz the battery got down to 14% & I have decided to charge it instead of letting it die at some point at a lower percentage
2. I should have mentioned earlier, that I still use the original N10 battery & plan to replace the original battery with a new aftermarket battery later on if I need to.
3. I use the N10 in an air-conditioned room for no longer, than half an hour at a time only browsing & reading articles with a short 10min video from YouTube.
4. Before lowering the CPU clock from 1700MHz to 1200MHz, the tablet consistently has shut down abruptly, at 27-30% battery level to my dismay.
5. Tried complete battery drain / cache reset to 0% in Recovery mode & then fully charging it while shut down 3 times without success.
6. So far lowering the CPU clock has made a difference & for prof now I am evaluating the N10 battery capacity with AccuBattery.
7. I charge my devices at around 20-25% or higher up to 80% to prolong battery life using apk's to stop charging or alert me.
I have switched to the UNOFFICIAL Resurrection Remix for Nexus 10 (ResurrectionRemix-M-v5.7.4-20161208-manta) MM ROM after rooting my N10 (Danke schön Corinna ) & had to update the baked in Kernel Adiutor.
Installing from APKMirror the "Kernel Adiutor (ROOT) 0.9.73 beta (Android 4.0.3+)" has allowed me to lower CPU MAX Frequency and have it stick after BOOT!

I don´t think so. The capacity of new battery looks really good. I use the N10 as wall-mounted control tablet for my home. With activated DT2W, full brightness, showing cams on motion, controlling home and audio over the day, my new battery runs about 28 hours before it stops. With old battery it was around 15-18 hours from full to off. My workaround: Reading battery with tasker and starts charging at 50%
I think the china batterys have different voltages than samsung batterys and N10 can´t work with this.

Hey,
That sounds very interesting. I may find out about that, when I replace the original N10 battery to my replacement battery from China.
I forgot to mention in my post earlier, that I am still using the original N10 battery. The original N10 battery keeps crashing at 30% unless I lower the CPU clock to 1200MHz.
After the first charge at (1200MHz max CPU) I got the N10 down to 20%+ before crashing to shut down & after the second charge I got it down to 14% at the same 1200MHz without crashing to shut down & just recharged it. Mind you I was just surfing the net & watching YouTube. I am also using AccuBattery to estimate the battery capacity atm. (Oh & don't install Battery Charge Limiter, because it boot-loops the N10 after install!)
DT2W sounds awesome. Which ROM are you using on your N10 to get DT2W, if you don't mind me asking?

I forgot to mention in my post earlier, that I am still using the original N10 battery. The original N10 battery keeps crashing at 30% unless I lower the CPU clock to 1200MHz.
After the first charge at (1200MHz max CPU) I got the N10 down to 20%+ before crashing to shut down & after the second charge I got it down to 14% at the same 1200MHz without crashing to shut down & just recharged it. Mind you I was just surfing the net & watching YouTube. I am also using AccuBattery to estimate the battery capacity atm. (Oh & don't install Battery Charge Limiter, because it boot-loops the N10 after install!)
DT2W sounds awesome. Which ROM are you using on your N10 to get DT2W, if you don't mind me asking?

Sometimes it shuts down at 20% and other times it won't. I'm almost pretty sure it doesn't have anything to do with advanced power settings or any kind of internal power settings with the kernel. There are no thermal configurations on this device and they don't add any drivers for it or support for it until much later versions. Heat seems to play a role especially down here Florida when outside. So far in my experience it's most likely to shut down at 20% if it's too hot and not likely to do so if it's been idle for a bit or not plugged in.

Hello, I worked on Nougat B09 nad now B10 as Slim 4 and Slim 5 ROMs version from this forum. My problem appeared suddenly with the following sympthoms:
1. Battery lasts on 100% during normal usage discharging mode, doeas not show proportional battery usage and drop,
2. Battery can drop suddnely (or very fast) to 50 % then switch off,
3. Battery shows inconistent indications when charging in "phone off" state (eg 1 %) or when charging in "phone working state" (eg 17%) or vice versa,
4. Due to verys fast drop of indication, there is never "the 15% level" detected and the phones does not enter "Ultra power saving mode" what worked pefrectly before.
5. When battery is 1% and the phone is switch off, it needs relatively long (eg. 20 min) time to be able to boot and work again, if not - it boots, shows there is still 1% battery and switches off (in fact battery maybe already is charged partially and could work, but there is wrong 1% indications and system decides to swoitch off)
6. Soemtimes phone charges very long and still shows eg 30%, but when switched on, the battery indicator schows that is charging and battery level grows very fast, eg 1% per second or two, as it would like to achieve proper indication as fast as possible.
Overall I think battery performace is not so good, the only problem seems to be that system is given wrog batterly level indications.

Can it be hardware problem? I installed Slim 4, Then Slim 5 with and without Magisk? Is there any software partition that can be corrupted and causes bad battery indications . Should I try to lock bootloader and come back to full stock ROM? (I only do not know which boostack to use, the rest I can handle).
I am using brand new stock charger and cable in very good condition (from this model, out of the box yesterday) , other good cable and fast charger from other phone (used so far and worked very well) as well as power bank with QC 3.0 so there is not a problem of cable or charger.

-Never lock the bootloader unless you're on stock ROM with stock recovery and unrooted
now that we got that out of the way, you should:
-install a battery calibrator (the one by nema is pretty good). this will delete the calibration files.
this will cover the software side
-install accubattery and charge from 0 to 100 some times. This will tell you how much capacity the battery has
this will tell you if it's a hardware problem

Thank for Your reply.
I planned to do it as follows
1. Make a backup what I have with TWRP.
2. Perorm full wipe in twrp
3. Flash stock bootstrap and modem with TWRP (I do not know what is boostrap since I came here from LeEco)
4. Boot in fastboot and flash stock recovery
5. With stock recovery install stock ROM Nougat B09 (B10 seems a little bit worse)
This will guarantee I'm running stock ROM. Locking bootloader is not needed, only if I would like to return it to Gearbest for warranty.

Ok I will try. Did you mean AccuBaterry app from Play Store? Should I use paid version? Did you mean charging from 0 to 100 several times in turn or just do it from time to time? How to deduce about bettery? As I mentioned the time it works on one charge seems to be good, only indicator is showing bad values causing the system is making wrong decisions. The AccuBatery will probably take the battery level valu from the same source as system does...
Sory for double post. I planned to edit it and then remove the last and to merge the two.

First of all, there's a much easier way to return to stock :laugh: either download the stock ROM from the Download Center (the twrp flashable ROM, e.g. B10 bootstack and stocksystem) and flash them, or use EDL Tool by djkuz and install a stock file.
If you won't relock the bootloader then there's no need to install the stock recovery! EDL Tool will install the stock recovery though. or you can download the zip from the download center and flash it
the free version of Accubattery is enough. And no it doesn't take the values from the system lol... it measures current on charge and time, and calculates capacity with it.
I mean charge from 0 to 100 several times, i.e. charge to 100, use the phone until the battery dies, charge again. After 3 times the result will be pretty accurate

Well, I am not sure thi will help me. As I already mentioned the problem is bad indication, not the battery life itself. Eg ot shows battery 100% but still charging, so if I think my battery is full and dosconnect the charger it can discharge fast.
If I think about some hardware repair is it battery that shows wrong values or charging module or either component? Has battery inside any chip controlling it? When I can read about it?

Well I also don't believe it's that, but i just wanted to get it out of the way, who knows. Did you try the battery calibrator? It helped me once with 30% shutdowns
NEXUS 10 Sudden Power Drop 38% to 0% and sudden Power rise from 62% to 100%
Greetings Good People,
My Initial Problem:
32Gb Nexus 10 purchased 2013, original battery failed in late 2017 (flickering screen and shut down at high percentage), first battery replacement fine until May 2019 when Nexus began dying after 30 mins to one hour you tube, jumping down to zero and shutdown (no flickering)
So what did I try:
(All done with original charger)
1. Bought two new OEM Samsung batteries with very recent manufacturer date and replaced twice. Now the nexus dies after 6 hours of you tube showing battery at 38% and then instant Shutdown to 0%, when charging jumps from 68% to 100%
2. Changed Rom's and wiped file structures (All the way from through Base Google Images from 4.2 to 5.1.1 to Lineage, rooted with TWRP and SU) >> Did NOT fix the Problem
2. Clearing battery stats.etc. ( incl completely discharge and Charge and all those cycles usually we do to calibrate the battery) >> Did NOT Fix the Problem - voltage reads almost 4.3 at 100% and less than 3.7V at 0%
3. Changed Multiple chargers (Wall Adapters/ Cable from multiple brands which i have at home.. LG, Samsung etc etc) >> Did NOT Fix the Problem
4. read a post about CPU power consumption and that Older Mother boards might not be providing enough Power to CPU. (This tablet is Old and has been used at least two to three hours a day for the last 6 years) so set CPU max to 1200MHz and Min to 200 with Kernal Editor but still powers off around 38% to zero, and jumps to 100% when charging.
Any other ideas or do we think the motherboard is borked or FUBAR?
