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

Possible battery problem?

I have charged my Nexus One yesterday for the first time. I live in holland so i had to use my USB cable, and the power adapter that came with my HTC hero to plug my USB cable in.
After the phone was charged 100%, i disconnected it from the charger and only downloaded + added a widget to my home screen. After i did that the battery was already down tot 97% :O:O
Is it defective ?

i noticed having to complete a few charge cycles.. charge fully, use it till dead, charge again
now it seems to hold out much longer

Hmm ok i'll try that. But did yours also drain this fast?

what setting is your screen on? seriously though, im sure some other battery experts here would know, but i think they take a few cycles to get to maximum efficiency

What do you mean with screen setting, and what should i put it on?
Sorry totally new to the phone hehe

I've noticed this too. However as soon as the battery reaches around 50% it takes a lot more to drain so it evens out in the end I guess

Hmm ok so it also went that fast on your phone? i have been using it for about an hour now and its down to about ~90% =\, concerns me a bit.

Found out something else, concering the usage of the screen. When i look here:
Menu -> Settings -> About Phone -> Battery Use
The phone tells what uses the battery the most or something, but the strange thing is that it says:
Display 55%
Isn't that very high? Maybe that is causing my battery to drain so fast

Battery meters are not an exact science. Its using what it knows about the battery's state to guess of how much % is remaining. The battery meter will need to be calibrated once, and then overall battery should improve with your next normal 3-6 full charges.
Again, you do not need to and you shouldn't repeatedly drain the battery to 0, only once is this needed to set the phones battery meter, unless you clear it (possible within amon ra's bootloader).
As for your observation, yes that is completely normal, there is not a whole lot of definition within 3% of battery as far as displaying it. What the real picture? Enter in #*#*4363*#*# on your dial pad and then go to battery information, and you'll see the accurate voltage. (this is also accessible from "spare parts" if you have it)

All %'s here are vs the amount of time on battery (shown at the top in h:m). If you just unplugged your phone and you go looking here, you'll see the display % VERY HIGH... because the screen has been on the entire time its been unplugged
Its a % after all of the usage since last unplugged.

i've noticed my battery life is much better since i got the desktop dock.. lots of people charge until the light turns green then immediately grab it and start using..
leave it for another hour or two and it seems to get much better.

dont know if anyone else has noticed this but the top corner indicator light turns green once the battery goes somewhere over 90%, leaving it charge longer will get you to 100

You probably found this by now, but one flick to the left and you should have a widget for WiFi, GPS, etc. The far right one toggles 3 levels of screen brightness. The brightest two settings really suck down battery.

just a tip, when you are draining it to recalibrate the battery, after you get to the point that the phone shuts off, boot into the bootloader and run that thing till it completely dies... i did this for my phone, sat it in bootloader with a bright ass screen for like 15 min before it finally finished off... get every last ounce of juice out of it before you start charging it back up

Hmm thanks for al the reactions guys. I'm going to recalibrate my battery now, and lets see if that helps a bit .
Then i have a other question, its not about my battery but since i already have a open topic i dont want to create another one .
Can anyone of you test the following:
When you are calling with someone, and your calling volume is on the maximum (so the volume of the speaker that you hold against your ear). Can anyone notice a little crack from the speaker when the other person talks a bit loud or make's a loud noise? I'm wondering if there is something wrong with mine. With several tones the ear speaker cracks a little bit, like the sound is to loud or something?

Yep sounds about the same on my phone, dont worry about it lol
The draining thing is from the old nickel days, the lithium batteries are made for daily use so just treat the phone as you would normally. The battery will get better as time goes by.
Also I am not having that problem with the speaker

Hmm, I have my device since last week (Netherlands) and the battery usage is frightening. Sucking it dry in about 24 hours. I haven't let it die out completely though: I thought lithium batteries were not supposed to be used that way. Ni-Cad batteries were used that way.
Ah, see here:
Guidelines for prolonging lithium-ion battery life
Lithium-ion batteries should never be depleted below their minimum voltage (2.4 to 2.8 V/cell, depending on chemistry). If a lithium-ion battery is stored with too low a charge, there is a risk that the charge will drop below the low-voltage threshold, resulting in an unrecoverable dead battery.[citation needed] Usually this does not instantly damage the battery itself but a charger or device which uses that battery will refuse to charge a dead battery. The battery appears to be dead or not existent because the protection circuit disables further discharging and there is zero voltage on the battery terminals.
Lithium-ion batteries should be kept cool. Ideally they are stored in a refrigerator.[citation needed]
Aging will take its toll much faster at high temperatures.[citation needed]
[edit] Prolonging life in multiple cells through cell balancing
Analog front ends that balance cells and eliminate mismatches of cells in series or parallel significantly improve battery efficiency and increase the overall pack capacity. As the number of cells and load currents increase, the potential for mismatch also increases. There are two kinds of mismatch in the pack: state-of-charge (SOC) and capacity/energy (C/E) mismatch. Though the SOC mismatch is more common, each problem limits the pack capacity (mA·h) to the capacity of the weakest cell.

So, if you want to brick your battery, by all means, suck out all the power.

i have a mytouch but i think the things i do can be used with all androids....first recalibrating is a good way to get a fresh battery...then the brightness also helps along with any wireless things u dont use like wifi gps etc.. they should be turned off an brightness should be low...i have downloaded a app lately called automatic task killer..i think this is better than any other task manager because other task managers dont kill apps wen phone is on standby ..apps r still running wen screen is off an automatic task killer kills them..i think u should download this and also have a task manager to kill apps wen u use the phone..another thing is charging the phone wen its completely off..wait until the the light turns green then leave it on for another hour or two then turn it back on....i have seen an increase in bettery life by doing all this...any one esle have any tips ..let me kno

Battery reading issues

Hey everyone. So I bought a second hand note 4 recently and have been having battery problems.
I did a full wipe install of CM13 and the battery dropped to 0% at random times and I had to plug it in the charger for the phone to even boot as it would just restart as soon as it turned on. Anyway, i thought this is probably due to faulty battery. I purchased another one and now this one doesn't reboot at random times but seems like the phone keeps reading the battery percentage wrong, sometimes it doesn't charge over certain percent, just gets stuck at 77% or 63% or any percentage really. If I remove the battery and plug it back in, it shows a completely different percentage everytime. I have tried wiping battery stats, do a full discharge/charge, nothing seems to help. Battery drains fairly fast too, once I manage to get it to 100% it shows that expected time is like 2-3hrs if screen on. Thanks!

battery displaying different percentage after u remove it and put it back in is normal i have 3 note4s all do the same (up to 10 percentage change, it either increases or decreases) but the other issues like getting stuck on a certain percentage are not normal make sure u have the genuine battery and try stock rom.

yeah, i tried stock and the same thing really. such a random issue. I just noticed that battery charges once I turn the screen on and use it , so it only gets stuck on random percent only with screen off.

yeah, i said I wiped battery stats, which is basically recalibration

once the battery is charged to 100% it also drops first 10-20% really fast and then it gets better but still I only get around 2hrs screen time

Oops my bad..Didn't read your whole post...

the only way to fix this replace your battery by new one
i tried all options (Format ROM - Wipe battery status - Getting back to stock ROM - Unroot - re Celebrate apps - Changing recovery-Removing battery from device for while sleeping - charge without fast charge - charge via USB)
i asked myself after that all of this headache doesn't worth 20$, i replaced the battery with new one and its working fine now

yeah, i replaced battery as well but it's still the same issue. old one at least charged fully but would randomly reboot on me, the new one doesn't reboot but drains extra fast and doesn't always charge fully. can't believe both batteries are faulty

I am sorry for summoning this old post but did you find any solution to your problem? I have exactly the same experience with my note 4.
Thanks!

Is there a solution for this problem?

Power down and then out-and-in same battery and my stuck-at78%... was 100% when started.
if you having problems with auto restarting.... download the app " WAKE LOCK" and put it on Partial Wake Lock setting... your restarts will be a thing of the past.

Battery readings going completely wild

So recently my phone (unrooted unmodded N910C) battery is being extremely weird. When I try to charge my phone, it sometimes doesn't go beyond around 70-90% but if I take out the battery and put it back in, it shows 100%. It sometimes also shuts off on its own at around 40% and when I plug in a charger, it shows sometimes 0% and sometimes 40% (but if I turn it on, it still says 0%). I've tried a lot of things, including discharging completely and recharging to 100% (powered off), factory reset, clearing cache, and quick starting battery and nothing seems to work. Does anyone have similar problems and has anyone found a solution to this?

The problem is the battery ... the catode pin inside battery is not working properly. The motherboard of the phone it just reading the voltage and temperature of the battery. Your percentage shown on status bar is based on what current intensity is received from battery. So just replace the battery... esxuse my poor english

Are you sure it's the battery? I took it out and everything looks normal, including the pins. Also, battery apps said that my battery health was good or should I not trust them at all? I just don't want to buy an extra battery if the problem is not with the battery.

I meant the catode pin inside battery not outside. It's your call if you buy a battery or not. I just writed here how the proces work because i have fixed lot of motherboard i knowing about this i have explained to you. Cheers

i have the same problem too and i tested every things and now i am really tire , i dont think thats problem was the battery , can anybody help me plz?

Had similar problem yes new battery at the samsung store the assistant said many note 4 batteries selling I got the last one. Maybe we got a bad batch or its deliberate. Maybe we could do a survey how many people have had to buy a new battery
Sent from my SM-N910C using XDA-Developers mobile app

I also posted a similar problem. In my case the problem is more alarming, because it's happening in two different batteries, one of them is rather new and fresh. It seems that it started out of the blue, I did not make any major change in the phone.
I am still investigating the issue, I'll be back with more observations.

Just an update on my situation: I bought a new battery and now the battery readings seem to be fine.

I had the same problem as you OP. The problem was definitely the battery for me at least. Bought a new one just the other week and now everything is working perfectly

If the affected battery is under warranty get it replaced for free. Or if the problem does not get solved after cross checking many possibilities. Just buy a new battery. Simple. Good luck.

My sm-j500fn shuts down instantly when taking flash pictures..

So, I wonder why my phone shuts down when is low on battery and I'm taking a picture with flash on. It does the same thing even when the charger is connected. Any ideas?

What ROM and camera app did you use?
Also, my guess is that the battery you're using might be deteriorated and needs changing (unless it's replaced with new and reputable battery).
It also happened on my J500H either, but minus the "flash on picture" problem, as my OEM battery drops immediately that, whenever the battery reched 55-60% left, the phone restarts itself and turned back on to just 20% or below 20 left.

I'm using ViperOs and rom's camera, but not the ROM is the problem, same thing happened on stock and other custom roms. I've changed my battery 9 months ago, it's not an original one. My original battery got very "fat" and battery dropped from 90 to 10. I don't know if it's battery related but I was thinking about this. It happens only when I'm low on battery, even if it's charger connected. My battery doesn't seem to have any problems, I'm using the phone all day without any percentage problems.
