Another battery drain problem - driving me CRAZY!!

I know there are already a lot of discussions on battery drain and believe me, I have read every single one of them. However, I think mine is slightly different:
When fully charged and using WIFI for 10 minutes, 10% of juice will be used. Listening to MP3 for 1 hour will also use another 10%. Overall, battery life is really bad but the key is it only happened suddenly. It have been very good up till now.
I have tested this on another battery and have exactly the same results so it is not battery related. I have also hard reset the phone and tested the battery with nothing installed and it still drains. A full charge only lasts me like 4 hour of very light use.
I installed Battlog and the power consumption is around 90 which I think is pretty low, but at times, even with this low consumption, I can see the battery usage literally falling before my eyes, like 5 % in 5 minutes.
I have also tried the HTC battery test, i.e. fully charged the battery, turned on plane mode and full brightness. After one hour, it only used 8% which I thought is normal. However, if I start using the phone by just simply clicking around, it will start dropping.
I believe the phone is fine on standby but once it starts doing things, even simple operations like moving around folders, it starts consuming a lot of power.
This all happens after an overnight charging episode when I noticed that the light stays amber in the morning and the percentage stays at 80%. I soft reset the phone and it immediately show 100%. This has never happen again but my battery usage is never normal since.
All in all, I think it is somehow hardware related, like the battery gauge is bad or the charging is never complete but it still shows green. It is still under warranty but I think will be very difficult to convince the service centre that there is something genuinely wrong with the phone.
P.S. Should also mentioned that I am using the stock telstra rom and have also cycled through the batteries twice before testing.

I had the same problem...
You should try resetting you battery:
1: let your battery drain to 0%
2: fully charge your battery while keeping your phone off!
this solved the problem for me..

I had actually "reset" the battery but only drain it to 5% before recharging as I have read that it is not safe to drain to 0%. I'll try to completely drain it tonight and recharge. Will report back.
btw, I noticed that when the battery is charged to 100%, the led stays amber for about 15-20 minutes before turning green. Is this normal or should it turn green immediately after reaching 100%?

Tried completely draining the battery and charge overnight but have no effect. The problem persists. So this is definitely not a battery problem.
I guess the last thing I can try is charging the battery with a standalone charger or another HD to see if there is problem with the charging mechanism in my phone.

The latest Telstra rom seems a bit better on battery

led amber
The led amber must turn to green
immediately after unplugging.
some thing is wrong with your charge
system .

aidinali, can you please explain what you mean? I thought the led will go off if you unplugged the charger. My problem is that after reaching 100% as indicated on the phone, the led stays amber for another 15 minutes before turning green.

Well , I'll correct & explain more....
1-when you reach %100 ,the led will turn to green immediately (if you’r phone is plugged in).
2-if you unplug ,the led will turn off (as you said ).
The problem is that since the battery meter in HD has not been defined by percentage , it doesn't match with
Apps like battery level or battlog .so when you see %100 on them , it' s not "real % 100 ".

I believe there is something wrong with the phone as the percentage usage and charging status do not match. However, since the basic HTC software does not have any battery usage in percentage, it’s hard to convince the service centre that something is wrong.
Any software that shows the battery as a percentage all have the same reading, so I assume they all rely on the mainboard for that information. There is obviously something wrong with either the charging process of the phone or draining more battery than it needs during usage.

I have 100% exactly the same problem as in the original post.
Does anyone else?
I have also tried 2 batteries and had exactly the same results with both, so I also know it is not the battery. The only app I have installed other than Dutty's 6.5 rom is Tomtom which does not need to be run for any of these issues to occur.
Any chance on warranty? I think it's software...

Try a different ROM. I've been having the same problem. I just flashed a new ROM about an hour ago (partly because Dutty's 6.5 kept freezing). I'm hoping both problems will be solved now.

i've found the latest radio rom to make a big different to battery life. 1.14.25.24_radio
the previous radio rom (1.13?) did suck the juice and made battery last 2 days less than 1.14

Try charging with a different charger. Ie. connect a USB cable on your PC and charge it from there.
I've had very similar problems with the stock charger a month after i got my TouchHD, and ended up testing with my old P4350 charger and all problems went away.
I've had similar drains even witch WiFi off, no emails, exchange or 3G access...
Now i'm getting a whole day's usage and i'm left with 30-40% battery, with 2 hours average talk time

I've tried with a number of chargers.....battery still sucks.
I've just switched from Dutty's to Energy ROM, radio is 1.14
If anything...energy drains more quickly than Dutty's
It says it drawing 350mA

Ok, I've used Energy ROM but now using Dutty's Leo. The only thing I've loaded so far is Battery Guard which say it's drawing 98mA when on standby(ie....backlight goes off). That'sa massive difference on the 250mA readings I used to get....now all I have todo is figure out which program I'm loading that is killing my battery.
That still only equates to 12 - 13 hours on a good standard battery with no use at all.

Standard battery should last longer. Sounds like your battery may be slightly faulty. Make sure you let battery drain fully before charging, and always try charging with device off. Should help improve strength.

I had same problem when i flashed miri's rom, hd got warm and didn't last, it cooled down in standby, the answer to my problem was that the wifi was not set to save battery mode, once i set it to save power everything was ok

Used 8% in 24 hours

Have been trying that for a month now....something seems to have suddenly worked It only used 8% of the battery in 24 hours! I live in the rainforest with no service so cellular was turned off...wifi on, but I only accessed it about 6 times......still,nothing has changed. The same conditions would leave me with a dead battery in 7 hours previously.
Time will tell if it keeps up this well.
By the way....Thanks

So basically you're saying people should drain down the battery to 1% or so and not to 0% (device dies when battery is out) to get a better battery strength?

Seems to be the general consensus. I'm still not sure if that's what made the difference for me but previously,I would put my device to standbye when I went to sleep at 10:30pm and it would be dead by 6am

Battery Drain after full charge with charger connected on a GB OS image

Seems most of us have not noticed:
GB stops the charger supply on our SGS as soon as the battery is fully charged and then your phone uses BATTERY instead of charger to keep itself on!
If your phone has some apps running which drains the battery fast, your phone will drain the entire battery and will shut down when the battery is dead!
This is very dangerous for the battery to discharge every day because of this bug and Samsung and most of still haven't seems to notice this!
I have tested this several times now and downgrading the Froyo fixes the issue.
This issue occurs even when the phone is sitting idle with minimal battery drain for several hours connected with charger (in such situation the drain is minimal with few percentage like when you disconnect the charger.
Let me know if some of you have different experience as my phone definitely has this issue which doesn't exist if I downgrade to Froyo.
We all can check this behavior:
Charge the phone till it says 100% charged. Use the phone normally or heavily for several minutes (like web browsing). Keep it connected to charger while it says "Charged" 100% for a couple of hours (to ensure that you did not drain the battery beyond charger capacity). You would still get much lesser than 100% charge after removing the charger (try using battery indicator tools which tells exact %age of battery).
This bug exist on all the Gingerbread images I have tried including official and those based on JVP 2.3.4
Read below how lithium ion batteries work best if used around full charge (without over charging - Phone and Battery has protection circuit) during regular use:

Deeper than 10% charging and discharging cycles unnecessarily will significantly reduce the lifetime of the battery. Hence when phone is plugged, it should charge battery to 100% and power the phone through charger after stopping charging. Samsung usually stop charging around 96% of full capacity of battery to avoid over charging. After disconnecting the batteries once around 96% was achieved, it will restart the charging cycle around 95%. Hence all builds till Froyo reported close to 100% charge level and never less than 95% when disconnected from the charger.
GIST - Batteries should maintain floating charge voltage to avoid depletion and wear unnecessarily while connected to the charger after full charge and phone should run on Charger ONLY. Instead, Samsung goofed up Gingerbread drivers to switch off the charger and run the phone on batteries randomly draining the battery sometimes completely. GB OS thinks phone is running on charger and hence show 100% charge and RAPIDLY drains the battery till it goes dead when batteries go dead (randomly)!
Last screenshot is from Froyo. Attaching more on a later post on how stable it is in Froyo.
EDIT 1st July - More screenshots on how Froyo maintains stable voltage and do not consume battery power (current) in post #57: http://forum.xda-developers.com/showpost.php?p=15228263&postcount=57
Screenshot #5 and #6 tells the DROP in battery voltage as soon as the charger is connected (200mV!) which speaks how much the GB OS consumes more when plugged in and STILL discharging!

Got the same problem with jpu. i didnt really realize this problem until this morning, just wondered why i had only about 90% battery in the morning after charging while with froyo i had about >95 in the morning.
today i slept until 10:00 and wow, battery was at 70(!) %.
when i plugged it in yesterday, ive got about 80% left (well, charging the phone every night seems to be a rite for me).
(and yes, im always listening to the sound when plugging the charger in).
so, as far as i can say, phone does not just stop charging at 100%, it also seems to consume much more power than it should. dangerous for battery, when the phone keeps plugged in for t >> t(100%).

This is a known issue of all current gingerbread builds. It will probably be fixed in due time.

and we wait for it
and we wait for it

Glad to hear it's a common issue. I was wondering if my batt/charger was faulty
Anyway, let's hope this gets fixed soon!

I noticed this the other day, hope it is fixed soon!

Yes, this has bugged me for the last month or more. Hence my question here about downgrading to 2.2.1...
http://forum.xda-developers.com/showthread.php?t=1135297
A temporary workaround - turn the phone off. Plug the charger in, then power on. Doing it this way should keep the battery topped-up after it first hits 100% charge - at least it does for me(I think reliably, but I can't remember). But it's a nuisance - especially as I tether for my home internet these days. Machines updating the OS overnight have seen me unplug to have less than 60% charge despite it saying 100% before unplugging, which doesn't last the day.
Unimpressed with Gingerbread on the whole. And Samsung/Kies for not letting me downgrade if the latest update(s) aren't up to much.

Actually I'm running eclair today to compare the battery. Got sick of unplugging it in the morning only to have less than 70% charge.

I don't appear to have this problem, I put my phone on charge last night at 23:30 as usual, the alarm went off at 07:30, then played a couple of tunes, phone showed 100%. Disconnected charger, went downstairs, checked xda for any news, saw this thread, checked my phone's battery level and it showed 98% after being disconnected from charger for 27 mins. Unless I'm using nav or maps my normal battery drain is 4% per hour in a reasonable signal strength area, so 98% after 30mins is normal for me.

Thanks for posting this I used my phone's gps yesterday when driving and I only just stumbled across this when I got where I was going, phone still said battery at 100% whilst plugged in but as soon as I turned the engine off and killed the charger my phone died with a dead battery.
Somewhat annoying to say the least, I'm going back to a 2.2.1 Rom tonight I've had loads of problems with all the 2.3 Rom's I've tried mainly lag and battery drain. I never seem to have any free RAM on gingerbread, lucky to get 50Mb on boot
oh well rant over the world can now continue ;-)

Well, woke up this morning and unplugged phone. 1.5 hours later and it's on 95% still, with a little usage. Didn't see that on 2.3.4. Using jg4 fully stock, only rooted. I might stick jsd on it today and see how it goes tomorrow. Not many apps back on it though. Surprisingly the phone feels quite fast at the moment. Don't remember eclair being like this. Not seeing much difference between 2.3.4 and it currently.
As I use go launcher, having gingerbread is probably less important for me cause I kind of don't use many of the features of it (the launchers etc) anyway.

I would appreciate if you could test the issue by using the phone heavily after full charge by KEEPING THE CHARGER CONNECTED AFTER FULL CHARGE (preferably playing 3D games or running benchmarks) and disconnect the charger to check the battery level.
Seems most of us are unaware of this issue and some confuse this with the excess battery drain issue after DISCONNECTING the charger.

Thank goodness I found this thread. I had thought there was something wrong with my battery. After unplugging my battery would instantly drop from 100% to 96%, once even 87%. Thinking it was something to do with battery re calibration due to me flashing new roms, i wiped batt stats many times and went through of arduous process of draining and fully charging, but to no avail. Now I will rest easy despite still facing this bug. At least I know I'm not the only one.

yep...i just flashed a couple of days ago from stock 2.2 (KC1) via kies to 2.3.4 (JVP) using ODIN. I have had it charge fully and upon removal of the usb cable, it dropped from 100% to 98%. Since then, I have gone through one full discharge and the subsequent recharge to 100% dropped to 96% upon charger removal. I recall reading about this somewhere suggesting a recalibration was needed, but I was just trying to get it up to 100% and didn't have the time to search forums (i was using a portable usb charger). I disconnected the charger and after reconnection and display of 100%, it would then drop to 97% instead of 96%. A repeat proved fruitless and so I tried to charge it while off. Turning it on after a bit I found that it was brought up to 98%. Repeated process for 99% and FINALLY 100%. Though the final 100% was achieved after a few 100% while off and while on charges. It stayed at 100% for a bit over 30 mins. I will see how subsequent charges behave...

This is a serious bug as it will significantly reduce the battery life due to repeated deeper charge and discharge cycle.

unless i've misunderstood, it seems to me that what will really affect battery life is the battery stats calibration. where it once would charge to 100%, it will now charge to, for example, 96%. Doing a calibration will make that 96% appear to the phone as 100%. From reading, it seems calibration is required for firmware flashes, so the more flashes and calibrations you do, the less battery life you will have since subsequent calibrations are done when the battery reading is less than 100 immediately after an unplug. Following the example above, the next flash could also have the same issue of displaying 100% and then 96% immediately after an unplug. The user would try to calibrate their battery yet again. Now this time, the 96% is of the previous full reading (which was actually 96% but appears as 100% b/c of calibration). So, the after a second calibration, the 100% reading is actually closer to 92.16% of the original pre-flash and pre-calibrated battery (96% of 96% of 100%).
hope that makes sense and someone can confirm, or instead (which i hope), prove me wrong as I would hate to think that what I stated is true since that will GREATLY diminish battery life artificially.

such overcharging (power off + connect charger and so on) is slowly killing battery
and it is not a bug that phone dsiconnects charger when it hits 100% and starts eating batt
anyways read my signature yellow part

Yeah, but in pre-gingerbread roms the charging started again when below certain value, so it stayed above 90% all the time.
Now you can drain the battery heavily by using it while plugged (and the battery always shows 100%), then unplug and have it jump down to like 60%, or worse, turn off.
The only way to restart the charging is removing and connecting the charger again.

i tkink thyve must decided that such upcharging when almost full shortens battery life

You are confusing recalibration and battery drain after full charge
The issue is after full charge, phone disconnects the charger and start draining batteries till it goes dead.
Let me rephrase the issue - batteries start draining immediately after full charge as the phone somehow start using battery INSTEAD of charger ONLY after full charge!
This is a serious bug as the GB drivers switch off the charger (instead of batteries) after full charge when the OPPOSITE has to happen!

Terrible problem battery

Hi!, im terrible problem for my battery
a long time (1 month) i bought two batteries for nexus 4 Originals, but the two battery only charged to 91% (long time jump direct to 100%) but low charged 9% without reazon
im try all for the solution the problem:
Reinstall kitkat 4.4.4 from adb
Franco kernel
CWM don't option wipe battery
Calibrate battery too, failed.

first of all try a battery calibration program like this: https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en
maybe it is a calibration problem.
as far as i know batter stats are not erased with a factory reset
then try an app like this :https://play.google.com/store/apps/details?id=ccc71.bmw&hl=en
it should tell you the battery capacity and see if everything is working as it should.
good luck! i hope that will solve your problems, or at least find out what your problem is!
P.S. if it is an app related problem, or wakelock related you can find it with betterbattery stats.

That battery calibration app is a placebo. The batterystats.bin file doesn't do anything to change the microcontroller inside the battery pack itself.

Allow the phone to discharge fully until it turns itself off, by normal use and not using a battery draining app (or a benchmark). Then charge slowly and continuously until full, without making the battery hot, eg. by USB port on computer.
If you discharge too quickly you risk getting the red light of doom.

Battery problem

Hi,
I have problem with in Jiayu S3 2GB. Under 50% battery drop to 0% in few minutes. Also battery doesnt last long , max 3 hours screen time and it is problem to use it whole day withnout charging, but normally screentime should be around 6 hours what i read.
I recived phone with Android 5.1 2015-06-23 tryed flashing newer version 2015-07-14, also tryed battery calibration, fully charging, discharging few times and still same.
When is fully charged voltage is 4,2V (measuded with app battery calibration) at 50% is only around 3,6V (this is almost 0 capacity for lion battery) and is turning off at 3,4V.
Have anybody simmilar problem? It looks battery is bad not just software problem, but dont understand that it is showing 50% for that low voltage.
Thank you

IF you are on lollipop then its software problem as 5.1 seem to have the battery bug, and never calibrate battery on MTK devices, Calibration apps mess up MTK phone,they are not made for mtk devices.

I recieved phone with defective battery, after changing it dont have any battery problem even with Lollipop.

I noticed that battery discharging very fast below 8% (Stock 4.4.4 13.08 and other KK versions)

Well, i had different problem
My phone didnt charge, no matter how much i change cables or chargers.
But when the device was shut down, charged well.
I bought mine from pandawill, so i sent them a mail,and they sent me another battery...
In the meantime, the problem had solved, maybe the battery calibration i did helped.
Anyway,i got now 2 batterys...

I also have the problem and have the following conclusions:
1. Battery level will be displayed correctly after a reboot. Otherwise, the battery level indicator doesn't change as quickly as it should: it doesn't go up as fast while charging and doesn't go down enough when in use.
2. The point where the battery indicator starts going down by about 5%/minute varies and is in connection with the time it has been used. After two days without charging and without using the phone for more than one or two phone calls, it happened at around 5%, while lots of screentime made it happen when the indicator was above 50%. Some experimenting made it clear that it's not the battery's fault (in my case, at least) but rather a software problem.
Using stock KK 4.4.4.

Hi,
I have problem with in Jiayu S3 2GB. Under 50% battery drop to 0% in few minutes. Also battery doesnt last long , max 3 hours screen time and it is problem to use it whole day withnout charging, but normally screentime should be around 6 hours what i read.
I recived phone with Android 5.1 2015-06-23 tryed flashing newer version 2015-07-14, also tryed battery calibration, fully charging, discharging few times and still same.
When is fully charged voltage is 4,2V (measuded with app battery calibration) at 50% is only around 3,6V (this is almost 0 capacity for lion battery) and is turning off at 3,4V.
Have anybody simmilar problem? It looks battery is bad not just software problem, but dont understand that it is showing 50% for that low voltage.
Thank you

Try to go battery settings and find out what application is eating your power.

Hi! I have this phone and few weeks ago I had a similar problem, when my phone had about 20%, it spend a lot of battery and in some minutes, it was without battery. I installed the Xtreme Rom and this was fixed. I hope you can fix your problem too with this.
Sorry for my bad english

Battery not charging when on - Solutions ?
Hi all,
My Jiayu will not charge when the fone is on, will only charge when switched off.
Any suggestions ?
Thanx Geoff

Known problem.
Saw it at my phone and in another phone.
How to solve: charge with original charger and cable and then switch to the other charger.
It worked for me twice.
Play it a little if its not working, switch cables,chargers, turn on and off...
Good luck.

Probably caused by battery calibration. Just use your prior rom from 100% to when it shuts off a couple of times to retrain it.

If you use multiple batteries like I do, you'll never be able to calibrate, and will just have to live with this issue.

Well not entirely true. Ur battery have the chip that tells the system how much left the battery is. I often have those prob. But now is gone. I just charge until 100% let it 10min charged. Then use it until it off. (Really really off.) Like when the battery circuit stop the battery not the phone shutting down. After that charge until 100% and after 100% i let it charge for 1hour to make sure it really 100% . done

Same here after last update. From 10 to 0% in second

+1 here
Thats why I utterly I hate sw updates.
My Galaxy NOTE 4 SM-N910C

Same problem here ,, considering buying a new battery but afraid that the problem isn't from the battery and get the same drop again with the new on
my phone is 1 year old

i had the same problem, so what i did was to flash the Rulinglite ROM for my note 4 910 C. it works fine now.

Hey guys, I got the same problem. Sometimes it drops from 15% to 4% in a few minutes and then from 4% to 1% in another few minutes (without using phone ofc).
Also, when i charge my phone - it shows me 100%, but when i reboot it - i got like 94%. Few minutes later - again 100%. After reboot - 95%.. etc etc etc... (charger is pluged on for all this time)
Do you have this problem?

Same problem here

my problem is that the battery percents are getting lower ery fast..if i make some actions that require more battery and i have 20% of battery, the percent goes to 16 so quickly and then the phone hangs up. I turn it on, it shows lesss battery, then it hangs up again and i need do recharge the battery. I bounght the phone at 2nd hand, i noticed the battery issue since i was testing it, but i love the phone. i am affraid not to be a hardware problem with one of the internal components of the phone, that killed the battery...i tested the battery on Note 3 and i am sure that the battery has a problem. What if i buy a new battery and a malfunctioning component of the phone damages the new battery too?

For me: i will dial *#0228# press quick start and wait till phone lids up connect charger and charge until 100% and then dont unplug first leave it there for 30mins or more and then unplug. ( do not unplug it halfway )
Second i switch off my phone take out battery and wait around 3 mins and then put back in and start charging it to 100% without switching device on, also same thing leave for sometime before unplug when it reaches 100%. you can also switch on after 100% and wait for sometime. ( as booting phone drains battery too )
hope it helps

Bought a new battery still drains at 10percent exactly,thought it's a lollipop issue,but even in MM it exactly shuts off at 10%.
