My Desire suffers from the following problem: whenever it's connected to AC, it will charge until 100% but then after some arbitrary time period it will discharge quickly to 90% after which it will slowly charge again until it reaches 100%. This can happen two or three times each night. This means that if you take your Desire out at the wrong moment, the battery charge will be at 90% instead of 100% which is EXTREMELY annoying.
I'm thinking that there must be other Desires with this problem, since my previous Desire (which was replaced because of WiFi-problems) exhibited the exact same behaviour. Does anyone else notice this? Or is anyone else willing to check (by means of using Juiceplotter overnight) if his/her Desire suffers from this as well? I just can't believe that the two Desires that I own/have owned are the only ones suffering from this ...
I already contacted HTC Customer Support and they told me that they would pass on this information to another department.
It's common... even I have it.
Whether it's a security or a bug (or both!) is completly unknown at this point I believe.

This has been discussed many times, and the concensus is that it is normal. When battery fully charged, it will stop until it falls below 90% at which point it will charge again.

My HTC Hero did not behave that way, and HTC did not explain to me that it was intended behaviour either.
Also, that would mean that the battery plot is incorrect since it shows rapid discharges from 100% to 90%, such as in the following image:
Furthermore, it seems that this problem (or feature ...?) disappears on at least some devices after rooting.
It seems to happen to me more often than not when I take the phone off the charger each morning. It's annoying but I need the phone on, so charging it to full while turned off each night's not an option.
This is usually done to exercise the battery.
I worked with developing a phone, and we did the same thing, in order for the battery capacity not to degrade because it keeps trickle charging at 100%.
So you shouldn't worry about this.
same happens to me, however i charge it over night and when i get up in the morning uplug and it charges for another 30mins (whilst i get ready for work) and its back up to 100%/99% which i can live with

Hm, my HTC Hero did not have this 'great feature'. I'd rather buy a new battery when this one has degraded too far, instead of having a not fully charged almost 50% of the times that I unplug it.
It would be more acceptable on a phone that would be able to go for at least 48 hours without intermediate charges but clearly, the Desire (just like most smartphones) can't do that.
first, apologise for reviving an old thread.
but it seems that charing by usb (via pc) does not have this problem.
also, charging by ac causes the battery to discharge at a faster rate...
Battery falls to 90% as soon as I unplug the charger
Same problem here, plug the charger before I sleep, at the morning the battery widget indicates 100% and the phone light is green, then I unplug the charger and suddently (really suddently, I mean quite instantly) the charge indicator falls to 89-91%.
Considering the poor duration of a fully charged battery I'd prefer not to lose the 10% of the charge before start using the device.
I'm quite sure this didn't appen with 1.15 stock ROM, I suppose I'd noticed it in case...
I can't remember if this appened after FOTA update from 1.15 to 1.21
With 3.1 modaco ROM I had this problem and now even with 1.23.351.1 Build rooted and A2SD+.
I tryed different radio ROMs without results..
I contacted HTC customer support, they told me to use an app manager like Taskiller to close unneeded applications that drain battery... lol
Obiouvsly they don't know anything about this problem..
Any ideas? It really hurts me to start every day with 90% of the battery!!
Thanks to all!
Hey, I have the same problem since I updated OTA version 1.21, never happened to me before with 1.15. Now when I wake up, I have fully (100%) charged battery, but after a minute or two it instantly jumps to 92%.
Any solutions?
Same here after the last update.

I've just sent a e-mail to the customer support of HTC explaining the problem, as soon as I have an answer I will post it here.
It should be interesting to do a factory reset and test with a recharge without installing any other stuff. Is there anyone who have a standard ROM (not rooted, original kernel) and want to do a try?
While I was writing they answered... They invited me to go to the nearest collection point to test another battery if available.
I'm starting to think the problem is not hardware related if other of our devices started to suffer the problem after the update..
I'll contact them again and we will see what appens.
Meanwhile if someone want to try what I suggested, it would be really apreciated.
Customer Support official answer.
The official answer: Send the device to us for repair. First try with another battery if you want (an if you can find another one...).
I'm not too happy to send my 3 weeks old device to them for 20 days so maybe I'll try to flash the 1.15 or 1.21 official ROM to see how the battery works. If anyone with the same problem wants to try to downgrade, please do it just to help to understand which is the problem.
I am having exactly same problem, i dont think its a battery issue either :/
Is there anyone who rooted and "desire" (wow, what a joke! ) to try a Froyo ROM to see if the problem persists? I suppose it should be totally different from 1.21 or 1.23...
I feel a bit lazy at the moment , I've just done a good setup and I'd like not to redo it again....
Volunteers?

Mine is not rooted. I didnt have this problem before the update.
I have some apps installed and a few widgets but nothing "advanced" like different launcher, heavy widgets. After the update I did a hard reset and didn't even backup my settings (have contacts and e-mail via Exchange server). The hard reset didn't help at all...

So I understand I'll be elect "the" volunteer
Maybe in the next days I'll try...
I used the phone till it automatically switched off, pulled out the battery for one minute, tryed to charge the phone when totally switched off and it charghed and stayed at 100% so I'm quite sure it's a ROM related problem.
You can see the next charge in the attached image (thanks to JuicePlotter)...

No need to worry, it has happened to me a few times. remove it from the usb, make sure you plug it back into the wall charger and hold the power button looking at the LED on the top, it should go red. if not just press it and wait a few times. I know it sounds crazy but it has worked ever time. once the LED comes on, just leave it to charge.
My fix was to update my clockwork to 5.8.4.0 that fixed the USB isues

Thanks everyone - I rooted last week so I'm already running clockwork 5.8.4.0
I plugged it in the OEM charger and into a known good socket (house is 150 years old and some of the wiring ....well...)
anyroad, I left the phone for an hour and when I returned the amber charging light was on and it was showing 63% battery.
I think I might have the problem diagnosed. I keep the phone in a 3rd party leather wallet which also has space for cards and money. I usually charge the phone in this with no problem however I suspect that the jacket caused heating issues - the phone was running Audible for Android last night, and the combination of all caused the overheating.
In future I will remove the phone from the jacket before charging overnight
phew!

Same thing happened to me. Plug it to your computer with the USB cable (not to the AC charger) and let it be for 15 minutes. At one point, it will start charging. Then leave it for another 30 minutes before switching it on.
What happens is that it goes crazy and instead of charging starts to discharge, and when it discharges completely it will not even boot into the charging mode or respond to power button.

This is called FUD.
1) Modern Li-Po batteries don't mind being charged to full (damage occurs above 4.23V)
2) they don't mind temperature (to some extent of course)
3) they don't need to be discharged (yes, it can mess calibration, but it also wears them out)
4) all batteries in consumer electronics are protected, so even if the charger/phone does something stupid, they should not be harmed
5) battery explosions and fires are caused by mechanical damage or a short, charging circuit malfunctions are very uncommon
6) when you leave it plugged in, it will not harm the battery, though it depends on device what happens - the device can run from the charger and let the battery be, or it can run from the battery and start charging again at ~95% (this is what lenovo laptops do), or it can keep running from and charging the battery (this is what a HOX will do IMO). Everything but the first case wears the battery out, but it's so minor that you won't notice it at all.
This article was written for sake of having an article, it's full of misleading and incorrect information. I don't need to be a battery expert to notice that.
In short - your phone knows what to do.
Guys whatever you say but i had Samsung galaxy s before and its battery died because i used to keep downloading on atorrent all night keeping it plugged. Though battery was cheap just 10$ so no problem but htc has non removable battery plus it would be costlier i guess 30-40$ so i would recommend not to keep it plugged for too long

Hello everyone. newbie here.
My sony Z1c seems to have developed a bug/issue. 2 days ago my phone was on charge, green led at the top was on and my battery showed at 100%. I unplugged the device jumped into bed, set my alarms as usual. I then woke up 2 hours later then i should of to find my z1c was dead. Nothing was running in the background etc so instantly knew something was up. Tried charging my phone at work via usb>pc and it kept saying my phone is losing charge quicker then its charging (never seen this message before) . I could turn the phone on but the battery level stayed at 2%, as soon as it was unplugged from the pc it would instantly die.
When i got home i done a few "reset" searches and come across the hold volume up and power at the same time until phone vibrates method. This now seems to allow my phone to charge normally again and the battery goes past 2%. However again today my phone went dead overnight. So the issue is still there, im just able to charge the device again.
I dont appear to have anything running in the background
havent done any firmware,software,app updates in the last couple of days (again that im aware off, unless they forced any)
also noticed the phone gets extremely hot at periods for unknown reasons?
Anyone here able to help or advice? is this a faulty battery, software,firmware issue etc? any fixes
d5503
running 4.4.4
14.4.a.0.108
Thanks in advance
Have you tried a different charger? Charge it using wall charger with supplied cable. I don't think firmware is draining your battery. Possible that u r caught up with a faulty battery if u don't have any issues with charger.
My advice "Head to Sony Service Centre asap".
Have you 'ever' installed any custom ROM on this phone then reflashed/restored something later after accquired? It could be the underlying system's battery state is different than the current running OS' one. Try calibrating the battery a couple of times to see if that make any difference.
Hello. Thank you for the replies.
The phone charges correctly via mains and usb(laptop,ps4 etc) since i done that power+volume up reset. Pretty sure my leads and plug are fine. i could try different usb leads though. the charge level is certainly showing me 100% charge
I have never used any ROM's or Roots. i dont know fully what they are. I used to have a jailbroken iphone so it sounds similar. Id be prepared to do down any of them routes if it fixes my phone
Everything updated has been official releases. I dont appear to of updated anything recently though so i cant put it down to a system update or new app update. - something might have glitched somewhere i dunno
Charged the phone during my first post and again it says its gone to 100% after a couple of hours. unplugged the charger. restarted the phone and checked nothing that hasnt been on for the last 3 months hasnt turnt on and all seems fine there. So just left it in standby
checked it 10minutes later to see charge levels. am down to 87%
using gsm battery app it says 68.9% app usage, when i click that
android system 53%
kernel (andoid os) 19.5%
then i have a list of other stuff running all be 2%
them 2 shouldnt be that high should they?
then when i go default settings>power> batt usage
android system 37%
googleplay service 21% (doesnt appear to be updating/syncing anything. should all be off. never used syncing)
screen 14%
android OS 5%
cell standby 5%
the rest of the list are 2's and 1's
phone was cool when charging, since rebooting the device and unplugging it, its now getting hot??? would of expected it to be the other way around!!!
Might want to give it a go of this:

Hi again, Jcw i done a full factory result and everything now appears to be fine now. Phone has been on for 3hours standby and on 98% battery, It would have been dead by now and extremely hot at the back. Now running alot cooler. Thanks for the advice.
Have no idea what happened. Something was seriously draining the battery though. Glad its fixed. Thanks again
After the latest update my M9 charges very slow. It takes 6 hours or even more than that, even with the Rapid Charger 2.0
If I reboot my device before before I charge it, then it charges normally, in under 2 hours.
Any solutions?
I am trying to fing out where the problem is, and I suspect GSAM Battery Monitor Pro and maybe an app called Screen Adjuster that might somehow interfere.
I have an unbranded device and it runs the official firmware.
Is anybody else having the same issue?
Have you tried wiping the cache and recalibrating the battery by holding both volume buttons and power button at the same time for over a minute?
No, I haven't. Are there any other issues I should expect if I recalibrate the battery?
Have the same issue .. S-OFF, ARHD 8.1, Firmware 1.40.401.8
No solution yet :/
So it must be the new firmware. This is really bad. I have cleared the cache but I don't really see the point of recalibration. If I restart my device before charging, it always charges after the reboot normally...
I disabled GSAM yesterday and the screen adjuster app, but the problem remains. I wonder, is there anybody out there running the new firmware without this issue?
Same issue here. Stock non-rooted ROM, stock firmware, S-Off, unlocked BL.
Had also the same issue with 1.40.401.5, thought it would be fixed in the official update (1.40.401.8). It appears it's not... Bad news when an update supposed to solve issues brings new ones...
With 1.40,my charging is way quicker with a quick charge 2.0 adapter. GSam battery monitor reports higher ampere and a battery change ~80%/h now (from empty to 85% as usual). Before this, battery change stalled quickly but now it's stable.
Did you factory reset your device after the update?
Same problem here.
No factory reset after the update. Should I? Or is there another way?
I did a factory reset when I first noticed problem with slow charging. At first it seemed to work and it charged normal speed but now its back to slow.
My M9 will only charge when i turn it off, plug it in the ac. If its on, even though the indicator says its charging, it doesnt, help.
The update was supposed to improve (quick) charging... Instead it made it worse ;(
I'm curious if there is anyone who does not have this problem...

Mine charges a bit faster with the quick charger, but only after a full reboot. And only once, after disconnecting the charger it reverts back to verrry slow charging when connected again.
I've the same issue. All stock, latest firmware.
Unless i reboot the device, it takes 8 hours to charge. If i reboot it before plug in, it takes about 2 hours.
Something is wrong were...
Same problem here but it is intermittent. I plugged my phone in earlier and it charged 10% in 1.5h on a 2A charger. So annoying!!!!
This is a big issue for me since I cannot rely on my M9 to get me through the day without having a charger with me. I am going to stop using my M9 till the problem gets solved somehow. Sorry HTC but this is a big issue for me and despite the fact that I love HTC products, I cannot ignore this issue. Back to my iPhone...
I agree on the Factory Reset, I do it every time I take a OTA update. It's jus my practices as it solved issues in the past and I kinda stick to it...

no its a real bug, regardless of the charger, when it appears only a reboot solves it
anyway the 5.1 / 2.x update is close but yea bug like that will cause serious hurt
This past week, I purchased a 2014 Note 10.1 off Craigslist. I did check it out before buying it, and the device is in pristine condition, including the screen. It booted fine, and I went partway through the setup (the guy had factory reset it) before closing the deal. It is the wifi-only model, 3G RAM, 8-core Exynos version. It's white if that matters.
Anyways, a while later when playing with it some more, completing setup, etc, it just died on me. I wasn't home, and didn't have a place to charge it until I got home, but just figured that despite the device having said the battery was 99% charged, the guy keeping it unused for a long time might have thrown off the battery calibration. My understanding is that a Li-ion battery has one or more cells, plus circuitry that protects against overcharging and undervoltage conditions, as well as tracking the current charge state. With lengthy non-usage, the circuitry's idea of the current charge can get out of sync with reality, so I figured a few charge-discharge cycles would get it back in shape.
However, the situation after I got home turned out to be a little more complex. If I plug in the device to a power source with enough current (like the charger it came with, or my 2.1A USB outlet by my bed), it will run just fine while plugged in. However, upon unplugging, it would die quickly. Naturally, I assumed the battery was probably shot, so resigned myself to spending $50 on one. This is where it started to get a little weird. It seemed that when I booted into either fastboot or Odin mode, it would stay on much longer than normal, while unplugged. I'm talking hours, rather than between several seconds and several minutes while booted into the OS proper.
This lead me to believe that perhaps it wasn't my battery itself, but rather a glitch in the OS that was causing it to shut down. When I say shut down, I mean an immediate full-off state, not a nice shutdown or one preceded by low battery warnings. It just clicks off like a light that's been turned off. However, trying several different firmwares, including a couple custom ones, has not yielded any improvement. The issue remains.
The device was stock 5.1.1 when I bought it. I tried flashing KitKat (various images downloaded from SamMobile), but for some reason, it would still say it was running 5.1.1. I tried xKat, as in this thread. That results in 4.4.2 with the associated customizations, but the shutdown issue remains. I tried CyanogenMod 13, as instructed here. It works fine, notwithstanding the same issue. In between the stock firmwares (pushed to the device with Odin) and the custom ones, I would do a full wipe through TWRP.
I've popped the back off, disconnected the battery, waited a bit, and reconnected it.
Now my question: does anyone have any idea what's going on? If it's a dying battery, then why does the device say it's got a nearly full charge, and why no low battery warnings? Why would Odin mode or recovery (TWRP now) seem to keep the device powered up so much longer? Sure, they draw less power, but hundreds of times less power? I doubt it. If it's some hardware issue with the chipset/motherboard/etc, then why does it only manifest when running on battery, or a low-current USB connection? If it's an issue with Android itself, then why does nobody else seem to have this issue (googling revealed nothing that matched my symptoms), and why did several different versions exhibit the exact same problem?
I really don't want to spend money on a new battery and wait a few weeks for shipping if there's something else I'm missing that could get my device functional for free and a lot faster.
My tablet had a similar issue, in that when you would get to the 15% mark, I had maybe 3-5 minutes before it would get to 0% and abruptly turn off. I used the battery calibrator app for rooted devices, followed the instructions, and now all is good again. For me, I noticed a variance from what the OS was reporting and twrp was showing in between flashing. For what its worth, I'm on the KitKat bootloader, and haven't used an official Samsung firmware since KitKat. Oddly enough, the battery calibration having been off survived through lollipop and into marshmallow. Hopefully you can get your tablet back on track.

That's a bit different from my issue. Even when the device reports full charge, if I unplug it, it usually dies within seconds, and always within 2-3 minutes.

I don't think that's going to make a difference for me. From what I was reading, all it does is delete the batterystats.bin file (hence the root requirement), which doesn't have anything to do with calibration for most devices. It just contains the stats for how much battery drain various things have caused, during this 'running on battery power' session. It's also reset every time the device is charged. Read here for more info.
Furthermore, even if this were not the case, I'd conclude that wiping the system partition (indeed, all partitions except recovery) would have cleared this data.
Still, that said, it's conceivable (though exceedingly unlikely) that some of these calibration apps might do something else, such as talk to the battery circuitry at a low level. Since I've got nothing to lose, I will probably give a few of them a shot. Do you happen to know which one it was that you tried?

In my case, the values seemed to track pretty closely, and with numerous freshly-flashed versions exhibiting the same issue, I'm pretty sure at this point it's not a software glitch. I've resigned myself to ordering a new battery. I just wish I was certain that it would fix the issue.

My understanding is that the bootloader doesn't change with flashing. I might be wrong though; is there a way to check the version?
Just a heads up. I ordered a new battery, which arrived yesterday. It seems to have completely solved the issues I was having.
My guess is that Android itself monitors the battery more diligently, and takes a more conservative approach to preserving battery life by shutting down when the voltage drops too low, while recovery mode would just let it run down completely flat (not good for Li-ion cells).
It's a moot point now, because it all seems good.
I know. I've seen the threads for battery drain and such, but I don't think there's a problem with "drain" so much, as perhaps a bad battery altogether.
I'm using my old M8 for my daughter, but after RUU, and setting up latest TWRP and all, then trying to install a custom ROM whether Stock or AOSP, when I boot into recovery, it goes from 100% within the ROM, to show 80% in recovery.
If off the charger, there does appear to have some battery drain, but I chalk that up to normal first usage.
However, it then shuts off @ 30%, but when I put it on the charger, it says @ 60%.
I've done the calibration method (hold all buttons for 2 minutes) trick, but there appears to be no help for the erratic battery readings.
Does anyone know if my suspicion is correct?
I'm on Sprint's last RUU.

Ive seen so many posts now that refer to the exact thing you mention. Phones turning off at 20-30%. Its claimed that this is due to a faulty battery and a replacement has fixed it. I do not have this problem, however, I did get a replacement 12 months ago.
That's what I'm afraid of.
Did you replace it yourself, or have a tech do it?

I replaced mine just Yesterday, with both speakers, chraging portero AND buttons, its not that hard AND not easy, you Will nerd a razor blade, AND see a few videos first, one thing to have in mind Is that i put a m9 battery on my m8, AND the phone works, but the phone doesnt recognize the aditional 240mamps,. AND the battery temp always shows 25C, but besides that everything is ok, waiting for the battery yo settle.
