I've noticed that when I leave the phone plugged in overnight it sometimes just seems to stop charging at a random point somewhere throughout the night and I'll wake up with a phone that is only at 80%, 65%, etc.. battery. It isn't fully charging and then just being drained again either, it just randomly stops charging. It will recognize that a charger is plugged in and even says that it is charging but the percentage indicator in the Settings pulldown doesn't move. This doesn't happen every night and it has never happened when I charge the phone during the day. I assume it only happens at night because I'm not at my desk using it. I can also assume that the device isn't taking 8 hours to go from 35% battery to 75%, it doesn't charge that slowly. Any ideas?

I would try the charging cable that came with it and if it still does the same thing I would say you have a problem with your phone.

Yeah, I have been using the cable that came with it. I've tried two different ones. I will try to see if it happens when charged through wall outlet.
Sorry for double post. Couldn't figure out how to attach image to an edit.
I looked at my battery settings and this is what I noticed. It looks like my phone is charging all the way up during the evening and then draining but the charging isn't kicking back or something. The huge gap in screen on time was when I was sleeping and there was no use of the device but battery is steadily draining.

As stated in previous post, I have not. That is the plan when I get home.
I have tried it through the wall charger for the past few nights and it charged just fine. I also tried it through the same cable that my N7 and Gnex were charged with and it still happened. I also tried various USB ports. Any ideas?

Is it possible the computer is sleeping and no longer powering the USB ports?
I had exactly the same problem for one night.
But it can't be a problem with my Notebook because
my Galaxy S charged just fine.
Probably due to power saving options on your computer, be they USB power saving settings or sleep related. If you want to charge faster you should definitely use the wall charger, USB charging is painfully slow for me... if i am using the device, load can exceed the incoming current and the phone will still discharge. Moral of the story > USB charging = useless.

It really isn't a matter of slow charging. I'm charging it overnight so the speed at which it charges doesn't matter to me. As long as it is charged when I wake up. I've been using the same computer to charge my phones/tablets/cameras for two years and I've never had a problem. I'm not even using the device though, it is at night when I'm sleeping.
I have the same problem all of a sudden. Happened twice in the past week, never happened for months before. I never charge from a computer, always with the provided adapter and cable from the wall. A few hours into the night, before the phone is at 100% (varies from 70-90%), it just stops charging. Battery graph looks very similar to the one in this thread already posted.
I wonder which device switches the current off, the phone, or the wall adapter. I would have guessed the phone, and if that is correct swapping the wall adapter won't do anything.
Or you can use Fast Charge from Google Play and flash Franco Kernel.
Then you'll be able to switch from USB Charge to AC Charge by charging with your computer.
However, the battery will heat and you may consume its life, so do not do that too often, only when necessary if you expect using your phone very long times as i do, i just change phone every 5 years or more, depending of my needs.
Also, i noticed than USB Charging slowing down the charge at around 80%, but still charging, i read with Battery Monitor Widget, and i seen it will gives minus ampere.
I almost forgot, you may also calibrate your battery, the first time, charge it to 100%, then remove the file "batterystats.bin" from /data/system or wipe it threw Recovery, that will ensure you to use your battery to 100% next time.
Mine seems to stop charging at 100% and go back down also. Mine usually is between 95-100% when I wake up though. Is that just how this phone works to protect the battery? I've never noticed this in any other phone I've had.

Hi, came across something strange this morning, when i took my phone off charge ot said 91%, but i always take it off at 100%, so i plugged it back in and now the battery is at 86%. Any ideas people?

I read somewhere that x10 has an auto disconnect function.. if your battery reaches 100% it wont charge further until it drops to 90% i think.. also check if the temperature have gone too high.
dial *#*#4636#*#* and check battery information..
I checked it, temp was 40c :S
Sent from my X10i using XDA App
not only does it not charge if you plug it in when over 90% (unless you power it down, then plug in. it will turn on and charge up to 100%) but it also turns off charging while plugged in. this means if you are listening to music, or streaming something while plugged in it will still lose charge until it hits 89%, then it should start to charge again, or if you plug in over night you could wake up to 90% charge depending on when it hit 100%. this kinda bugs me but i have learned to get around it.
you might have an app running in the background that caused your battery to run low and the temperature to rise. if you installed anything new recently try uninstalling it and see if the charging cycle fixes itself
For me is the same so far...

I noticed something similar go this but at lower power levels.
From a charge (starting around 8%) I found that even while plugged in,me playing with the phone caused it to drain battery faster than it would charge. So I left it alone for a while, then experienced the same issue around 50%.

i get the same problem too, but only when using my car charger. if i try to use google maps as a sat nav, the battery drains rather than charges. a real big pain to be honest, means I can't just use the sat nav features of the phone when ever I drive.
hi I also have the same problem however to add in to it also i noticed that battery is not charging they way it use to be i am using the stock charger that came with the phone and i have noticed that since i have updated it to R2ba020 the battery does not charge , i mean earlier i use to get it charged within 4 to 5 hours and now it just get like 40% charged in the same time.
anyone has any idea.
I am experiencing the same issue. sometimes the phone charges very slowly. And as soon as it reaches the 90% mark the LED turns green, the status says charging(AC), battery icon has that charging mark on it. but it does not charge any further, rather the battery starts draining. Once the charging went upto 93%, but thats the best it got so far. I guess it has somethng to do aith the battery temperture. what is the temperature limit if any one knows.
Okay... starting to get really agitated at the battery now. Charged it overnight for over 8 hours, and woke up to my phone at 72%. That's just inexcusable for any cell phone, smartphone or not.

Do ypu guys think it could be the 020 rom? has anyone checked if the 023 update is avaliable from seus? Ill try it tomorrow. But tbh this is really bugging me now, great phone yet there is always an issue......:'(
Sent from my X10i using XDA App
yesterday I charged it through USB. at 90% it stopped charging and started draining. unpluged the phone and repluged it after 5 minutes and it started charging and this time it went all the way to 100%. today I charged it through AC and it chrged to 100%. I think its working OK now. The only difference is that i installed Battery Indicator from market, but am not sure if that solved the issue.
I have the same issue with my phone after updating to the 020 firmware.
It will charge to a certain point and the power will drop off after that. It will never reach MAX.
This is Bad.
Not sure if it's related, but I upgraded to R2BA020 (Rogers) this weekend, and now whenever I tether via PdaNet my battery drains at quite an accelerated rate (15-20%/hour). Under the stock Rogers ROM this wasn't the case, and though the battery would drain while tethered (more power usage than was gaining through USB charging), it would be around 3-5%/hour.
I checked and the phone is receiving what appears to be a proper charge via USB, but I'm not sure if it fills to full or not.
It almost seems to me like 020 messed up how much capacity the phone sees the battery as holding. I did fully discharge the phone last night.
I'm using the 023 rom now. Completely skipped over the 020 rom so I can't compare the two, but in my experience, the 023 rom rooted seems to drain more battery than the 014 stock rom.

I have the same issue but i tracked down the problem.... its something to do with the usb socket on the phone i think.... When i plug it in sometimes starts charging sometimes it doesn't... but if i push the usb cable gently a little more in it starts charging again.... i think the usb socket is a little to big... and cable doesn't stay in place... most of the time if i touch the phone or the cable while charging it stops right away so I think I'm right....

If that's the case you'll want to RMA the phone. It's not normal.
I had that happen with my old iPAQ 910c. Eventually, it wouldn't charge at all as the USB port had become so loose. At that point I had the phone replaced by my carrier.
the socket is not loose its just too big i think ... doesn't move at all...
So I started charging my phone earlier and it took forever, and the phone got very hot, but I didn't think more of it and unplugged it. Then it dropped under 15% and I decided to charge it again. It's been in the charger for 30 minutes and it's only gone from 9% to 10%...
Am I the only one with this problem? =S
Edit: It still gets very warm.
Turn it off and on?
Sent from my X10i using XDA App
I was sort of hoping it went without saying that I had done that.
I've also tried:
Charging it through my PC
Charging it through the wall charger
Both give the same result as listed in the first post. Also tried removing everything (battery, simcard, mem.card) and reinserting it.
Still it gets very warm and charges almost nothing! =S
Are you using a different USB cable or charger than the one provided?
I have tried several different USB > Micro cables and not all of them have worked properly.
My old BB wall charger works fine, as does my old Motorola one (both plug a USB cable into), but wife's iPhone one does not.
I really don't think that's the problem... I finally got it up to 100% with the wall charger, but when I restarted it after having reinserted the MicroSD, it had dropped 13%. In a few seconds, does not make any sense =S
Night time here now though, so gonna see how much it loses in just standby, if it's a lot I'll try reinstalling the update. But this seems to be an isolated issue?
I noticed that charging it with the wall charger is at least 3 times faster.
Also, you're right, the phone can get really hot while charging and at some point it even stops charging when it's too hot , it happens easier when charging using a computer since the charge takes more time, the only thing that helped in my case was to remove the battery cover and blow some air on the battery
The problem sin't that it charges SLOWER, it charges about the same for both, currently. The problem is that it hardly charges at all...
Also, it was at 100%, then dropped to 87% just with me turning it off, reinserting the memory card and turning it on again.
I went to bed at 2am last night, then it had 87% battery. When I woke up at 9am, it was dead.
your battery is faulty
email SE telling them your battery wont charge but that your friends/spare/new battery does charge when in your phone (to rule out the usb fault that some x10's had) and then they should send you one out.
Hi all.. My Evo Shift 4G seems to have developed a charging issue.. I'm not sure if the phone is not reading the voltage from the battery properly or what.. Basically, my phone will not charge over 85%... In other words -- it never reaches 90%+ on the phone, which would typically cause the charging indicator to change from amber to green.
I've watched what the phone supposedly sees with 'Battery Monitor Widget'. Currently, the phone has been on the AC charger for about 7 hours... The phone reports 77% charged, 32.1 degrees C for the battery, 4024mV. I've watched it during the charge cycles, and when the battery is low, the current is definitely being applied to the battery -- around 500-600 mA. When it gets close to 70%, however, it starts ramping down the current.. Right now, at that 77% level, it is showing 0mA being applied to the charging circuit.
I have 3 batteries -- two HTC original batteries, one about 2 weeks old, the other from March.. I also have a 3rd party battery.. All of the batteries behave the same in MY phone.. If I throw the batteries into a couple of friend's HTC phones (one has a Hero, the other a MyTouch 4G) -- their phones report the charge at 100%.
I also have an external charger -- if I charge the batteries in that fully, my phone shows 85% charge, while my friend's phones will show the batteries at 100%. Likewise, if I put their batteries in my phone once theirs are fully charged, my phone will show it at 85%.
Anyone know how or if I can correct this?
Thanks,
Rick

It is rooted.. I get the same behavior on CM7 or the rooted OTA 2.3 update by x99..
I've tried clearing the battery stats.. That has not worked.. I believe it comes down to a problem with how my phone is reading the voltage of the battery..
Worked for me...
I had the same problem but the it could charge to 93ish% percent, not 85. I fixed by clearing the battery stats, setting the screen to never go off, and left it on overnight (while I'd been using it all day), recharged it to full while it was off the next morning, and unplugged the charger and reinserted it until when I could plug it in starting with the light green. Following, I turned it on while it was still plugged in, downloaded the battery calibration app from the market, and calibrated it.
Afterwards, I've been able to get the same outrageous battery life that others claimed they got on roms like evervolv and miui, and been able to charge to full. See if this works for you.
Have you tried a different charger? Say if you are using the wall try a usb or if using a usb try a wall. Just a suggestion don't know if it'll work.
EDIT: Looks like I need to follow my own rules and read everything fully. Sorry for the ignorant post it'll prob be no help!

I've tried charging via a number of different chargers:
1) HTC AC Charger (5V/1A)
2) Computer USB (5V 500mA)
3) Palm Pre AC Charger (5V/1A)
4) Palm Pre Car Charger (5V/1A)
5) Aftermarket AC Charger (5V/1A)
I think there may be a problem with CWM. I tired the wipe battery stats a few times (7) and it seems like it didn't do anything. Then I downloaded an app from the market called battery calibration, wiped with the app. I think it actually worked with the app, as my run times went from about 8-9hrs to well over 24. Hope this helps - Viperspike
From what i understand, charge to 100%, turn phone off and charge a little more, reboot, wipe batt stats and unplug. Run all the way down to zero (phone shutdown) and restart one more time (it should immediately turn off) Then plug in the charger, and reboot. Once on the charger make sure it charges uninterrupted until it reaches 100% the first charge.
Thats the problem.. I can never get anywhere near 100% -- 85% is the top.. At that point current drops to 0mA and the charging circuit turns off.
I did send a support request to HTC.. This is their response:
You were having issues with the battery life on your HTC EVO Shift 4G. You mention that you have tried another battery but you cannot get the LED indicator light to turn green or the charge percentage to go above 85%. You state that you have tested your two batteries in a friend’s MyTouch 4G and HTC Hero. Both devices show 100% when there is an indication of a full charge. Unfortunately, there might be another hardware related issue causing this to occur so I would suggest you consider a repair request for your Android device.
There seems to be a bug, where if i leave the phone connected overnight on the stock charger and wifi is off when i wake up the battery is at 80% or less. My theory is that as soon as it reaches 100% it stops charging, has anyone experienced this?

This is happening to me as well; I've come to believe it's a faulty charger, actually. Or a charger designed that way. But the charger's fault regardless.
First occasionally, but now for a few nights in a row, I've found a phone plugged in overnight to be at 80% battery in the morning. When I look at the battery graph, it appears to have charged rapidly to 100% (or close-to), then started slowly discharging. However, with the battery use screen open, I also noticed that the status was rapidly changing between "Charging (AC)" and "Not charging", spending most of the time in the not charging state, despite a constant plugged-in icon in the notification area. This behavior persists regardless of wifi state and through many reboots; BUT, it hasn't happened at all yet (with just limited testing) when plugging it in through the adapter for my last phone (an HTC), nor does it happen when charging via USB. I don't know if the LG charger could be designed that way, where it stops when it's full, or if it's just a faulty unit that needs replacing. I'm going to try it on the HTC wall unit overnight tonight to see what happens.

I'm actually having a similar problem... For me I noticed that the screen stays on while the battery is discharging while on AC charging mode so it may be a different issue. It doesn't always happen but when it does, I'll be sitting around 75% when I wake up in the morning.

Turns out this is caused by using a USB extension cable... it would say the phone is charging on AC but there would not be enough current going through. When I plugged the the stock usb cable in to the charger directly, it charged fine.
Hi there,
got a strange problem.
I plug in my N4 in the evening, it is loading up to 100% and there it begins to DISCHARGE (or in other words, stops to hold the battery at 100%) although still connected to the charger. In the morning I unplug the phone and have just around 70% left ... see attached screenshot.
Using stock charger and cable that came with the phone.
I hope this is not intended by Google? Running Android 4.2.1 Stock.
is this the only time it happened?
It is probably because of the charger. They definitely didn't include the best charger out there try another charger, you'll see improvements.

Thanks! Used my equipment (powered USB hub with another micro USB cable) from old phone until yesterday, and read about charging problems when NOT using the charger and cable that came with the N4. To see if that is maybe the problem I therefore unpacked the "stock" cable and charger - but it didn't solve the problem.
The most strange thing is, that it charges perfectly up to 100%! I would expect then that it stops charging to avoid overloading, but that holds the charge level at 100% until unplugged. I think this logic is not within the charger, but controlled by the phone itself (Software / Hardware Unit)?

Hmmm ... never experienced this 15 years mobile phones (at least 4 of them using Android and tons of different ROMs ...). What would be the purpose to plug in your phone in at 22pm, stop charging at 1am and begin the fresh day at 7am with again 30% loss of capacity? I would need to carry my charger stuff all day with me ...
As I said, I fully understand that it stops charging at 100% to avoid overloading - and also see the sense in this here -, but usually it should HOLD it at 99-100% until you unplug and not lose capacity while still connected to the charger.
Cheers
did you plug it into a USB hub that was plugged into a computer? that might be your problem. My N4 has issues charging from USB ports... it never holds charge properly.
This happened to me previously, ended up swapping my charger back to my Samsung OEM one and havent had the problem again.
Another time that this could happen is if you're charging via your USB port on your computer and you shutdown your computer which it will still show the charging icon but the status says not charging which could be changed by replugging the phone and/or having BIOS settings that enable usb power draw etc...
Just found this one ... maybe I'm not explaining my case very well, but it seems I am not alone ...

Yesterday I used the wall plug. All the years before I used a SEPARATELY POWERED usb hub. Even if the PC is shut, the hub provides power to the ports. Anyway, it doesn't matter - Charging is working perfectly on wall plug, usb hub, stock cable, non-stock cable ... before reaching 100% and phone disscharges. Picture in 1st post illustrates the disscharge while still "charging" (last bar at the bottom)
it's def. not normal. mine doesn't discharge, it can stay plugged in all night and it'll say 'CHARGED'

Exactly what I would expect! Now that I found the others on code.google.com having the same issue I think there was a batch of devices having it and that I might need to RMA ...
Well the reason why I was mentioning the charger (unless you've tested another one) is because I was using the original LG oem charger and for a while it would give inaccurate readings on multiple occasions. Example being I woke up (used wall charger) and it said 70-80% and the charge icon was still there but on the status it said 'not charging'. Another time was when it said 96%, unplugged and replugged and it charged to 100%. Then I use the phone for a couple of seconds and it drops down percentage again 96%~ and when/if charged it will say 100% again (giving a false reading).
I was thinking it was the cord because I used my bro's LG charger and it charged the phone 96, 97, 98, 99, 100 and not 96 -> 100% therefore the cord may have been the problem. Went back to my Samsung OEM charger and it has been fine since then and never had any discharging.

I'm on 4.2.1 stock yes.
Thing is, that I'm not plugging it out! While being connected it suddenly starts to disscharge - Why the heck would you disscharge when you have a power source connected?! The "event" invoking the disscharge to me is the reach of 100%. Maybe this is a misbehavior of the overloading protection, to stop charging (as intended), but not restarting to charge at lets say 99% or 98% to get back to 100%. This would mean that when I'm using navigation in my car I would need to reconnectfrom time to time to trigger the charging again.

Yeah I know what you mean but its odd that I had this problem as well but disappeared when I swapped.
As for my USB/PC, that charges when the computer is on and off but when I turn it off, I would have to replug the phone to get it started again as it will have the same "charging icon" w/o it actually charging. My guess is that if the power source loses its power, even if its temporary it will stop charging. But when I using my Skyrocket a few months back I never had to replug the phone onto my computer to get it charging again but I do know that the computer will temporarily cut off power when you shutdown and bring it back to charge plugged devices. (didnt change any power states in BIOS).
So most likely it is something with the phone but it could also be a setting or some software error triggering a fail-safe or something.

I see definitely some issues in the charging logic in both of our cases here. You shouldn't have to replug your phone if you send your PC to sleep, as long as it still outputs the USB power. Since I would not expect the decision to charge or not to charge in the wall plug or in the USB hubs, I can only hope it is not a hardware problem of the charging electonic, but a software problem which could be patched. Also wouldn't I wonder if this has to do with the wireless charging option of the phone ...
come to think of it i had the same problem. charging from the PC when off via USB it would do the same thing as OP. charging through the wall works fine.
Well just found out I am maybe reposting the issue as I didn't find this initially ... similar (or same?) problem described here: http://forum.xda-developers.com/showthread.php?t=2031246
