Battery drains when charging

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

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......:'(

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...

[INFO] Asus No Longer Charging!

As of this morning my TF nor the dock will charge from the charger. I suspect the charger itself is damaged somehow but I cannot find anything physically wrong with it from the outside.
EDIT: Weird, after the 20th time playing with it, taking it apart, reseating the USB cord, etc, it finally started charging again after hours of aggravation. Hopefully it stays that way....
I'm thinking the inner pins somehow lost contact with the interposer. I've also noticed that the adapter gets alarmingly warm when charging. As in it's hotter than the PSU I use for my Alienware m17x R2, which is almost hot enough to give a mild burn.

My charger gets pretty warm as well. I think because its charging the device at such a fast pace.
Takes twice as long to charge my phone than the transformer!

Yeah I'm just hoping this whole thing doesn't keep happening. Had the charger on the dock for a while before I realized it wasn't charging since there's no indicator other than the LED. I'm just glad I got the dern thinking working again. Figures it would get fixed not 5 minutes after I post here and send a ticket in to Asus.

I wonder if cutting a few vents on the charger or at least blowing some air with a fan might help. Perhaps there is a thermal protection shutdown circuit.

there are several threads about this here one;
http://forum.xda-developers.com/showthread.php?t=1042868
i had the same problem, not had it since, something is definitively happening with the charger, changing sockets seemed to help

My charger actually died on me. It doesnt charge at all anymore with the included charger. I can still use the cable to charge off of USB, but that is sloooow. I bought an iPad charger (2 amp) and it charges a bit faster. At least I can still use my tablet until a replacement charger is available.
Just FYI I was told by Asus CS a replacement would not be available for awhile, and they wouldn't RMA the charger by itself.

Sounds like many of the charger problem is the contact between the country plug adapter and the charger itself. First thing I would do if it stopped charging is remove the country plug adapter , clean contacts and reinstall. Sometimes in the process of plugging in or removing the charger, you move contacts enough to either make or break the connection.

Loses charge significantly on standby
I left it on standby last night @ about 70pc. When i turn it on this AM, it is at 20pc Any workarounds?

Standby and off are very different states. In standby, it's STILL RUNNING. If you leave the WiFi on, it's still communicating over the network. Applications are still running in the background.
I did a test recently (right before I got my dock). I left the TF in 'standby' with WiFi on (turned off the sound) and went to sleep. About 9 hours later, the battery was down around 50%.
Next day I did the same, but I turned off WiFi. Battery ended up still being above 90%.
The workaround is turning it off. Disabling WiFi reduces battery consumption in standby, but it does not eliminate it.
And for the 'stopped charging from the AC adapter' issue, it seems that unplugging the adapter from the wall for a while seems to reset the charger.

I feel this is a shortcoming of honeycomb than asus. hopefully this gets fixed in a future update. Havent seen this behavior in any other mobile device.

Which part do you think is a problem with Honeycomb instead of Asus?
The dock issues or the power supply not charging? How can the OS be responsible for either? (save for driver issues with the keyboard, which Asus fixed with an update)

I actually had this happen to me, but reassembling the charger didn't fix it for me. I ended up restoring to fix it. Haven't had any issues since.

I had the same problem. Did as stated above... Left charger unplugged for 20-25 minutes, then gave it a try and now it's back to charging... All good.

Information of PSU model with known fault here:
http://forum.xda-developers.com/showthread.php?t=1081435

Possibly a related issue? My Transformer is now not charging although I believe either my cable is faulty or the connector to the tablet itself. I don't have my official Asus charger with me today so I plugged it into another USB power charger and I get nothing. When I plug the cable into my computer the Transformer does show up as a device in Windows however there is still no charging.

Charging issues.

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?
P.S Rooted but on stock ROM

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.

Weird charging issue

I usually charge my phone using USB while in the office. At home, I'll use the supplied wall AC adapter.
I've noticed that even though I'm using the AC charger, the stock battery display will show Charging (USB), which is not the case. Power cycling the AC charger usually fixes it to show Charging (AC).
Have also noticed that in some instances when it's plugged into the AC charger, the charging status would switch between "charging" and "not charging". Very obvious in the notification battery icon, where I would see the lightning symbol appear and disappear, about every half second.
I think there's an issue with the AC charger, or maybe it's the charging circuit in the phone?
Anyone experienced something like this before?
Cheers

Sounds like a hardware issue. If you want to run the test yourself, you can try swapping the charger with another OEM Nexus 4 charger (don't try to get around this). But I'd contact Google about this if I were you.

Might be the stock charger if thats what your using i had the same prob and sometimes but battery would either stay on the same percent for a while or go down so chanhed the charger and its been working fine ever since i still use the stock box charger i just changed the cord

Do you guys think this is a charging issue? Temp is very high but still continues to charge at AC level. I have switched out my power bricks and cable but still have the same result.

It is due to temperature I believe. I have observed this behavior closely for a long time, so I'm almost certain this is the cause. I've seen it on the Galaxy Nexus and the Nexus 7. I can't tell you offhand the exact temperature they stop charging at, but I can tell you it's most likely between 50°-60° Celsius. You've got to let your devices cool off. It may be a pain, but it protects your hardware, so when it stops charging, your phone is saying "Hey partner, you think you could let me cool down for just a second? Is that too much for you or what? What's your problem, you dingdong?"..
... Or something like that. If that's not exactly what it says, it's very close.

Same here. Worked out for me it was a dodgy cable. Using the supplied cable through a laptop, I will also from time to time get the plugged/unplugged notification on the computer, which being audible made me realize how often it was happening.
The supplied charger brick now seems to work flawlessly with a different cable (ie, always says AC, no odd charging/not charging behaviour, etc).
Try that and see how you go.

I guess it's the cable. I've tried using a generic ebay cable and it appears to be working fine now.
What sort of mA values are you getting when using the stock AC charger?
Battery Monitor widget says that the phone's only getting around 500mA when I believe it should be getting more than that. I've enabled the USB fastcharge in the options. and have left everything at default. This is after waking up the phone from standby. Keeping the screen on drops the charge rate to 200mA thereabouts.
No music playing, 3G and connected to a wifi access point.

Charge cycling?

When my phone is charging it seems to randomly display charging rapidly, charging, or charging slowly. I'm running stock nougat and have tried the original charger and another PD charger with the same results. Is his a known issue or a phone problem?

It's possibly just how they charge.
Lithium ion batteries in phones don't generally charge at just one rate from 0-100%. Around 85-90% they slow down. And the last 5% or so may be the slowest.
That's probably what you see

Assuming you're seeing it switch to charging and then slow charging as it gets closer to 100% this sounds normal.

I thought that at first also, but it does it all the way through the charge.

Mine does this fairly often, and the battery percentage never matters. It happens equally as often at 40% as it does at 70% or anywhere in between. Additionally, mine will sometimes go onto the charger and just be stuck at "Charging slowly" and never change. Nothing's changed on the other end, either - it's plugged into the same port it's always plugged into. I seem to have better luck in getting it to charge rapidly when I plug it in with the display powered off, but that could be a bias I haven't eliminated. I have no actual statistical data to back it up.
I've opened a ticket with Essential Support, but haven't gotten a response beyond them asking a few questions and telling me they'd "look into it" (almost a month ago).
I will say that regardless of what the display actually says, the time it takes to charge fully seems to be fairly consistent (for the battery percentage it's at when I plug it in, obviously). But no, you aren't alone in seeing this behaviour. I'm on Oreo, too, not Nougat.

Mine does the same but still charge's from zero to 100 in expected time around 70/80 minutes,it tends to jump to slowly when nearly full .
Have to say battery life I'm getting is nothing short of astounding for a 3040mha battery

Thanks for the replies, I'll try timing it and seeing how long it takes.

same here with original wall plug and USB cable. Stock 7.1.1.
After reboot it stays on "Charging rapidly". until another day or so.

Oreo seems to fix it.

btw, seems that when I'm charging in Flight Mode it's always stuck at "Slowly Charging" , looking forward to test this on Oreo.

can anybody confirm that PH-1 is always stuck in Slowly Charging when in Flight Mode? (and if you are Android N or O). I'm wondering if it's my device or general issue.
btw here Essential support answer on that issue:
With the Essential phone the charging speed fluctuates and there are different factors that come in play, including the percentage of the battery at the time. It is to reduce the heat and to prolong the battery life of the device.
If your device is in airplane mode then all major processes including your cell network and GPS are off, therefore the drain on your battery is reduced that would otherwise need to be made up for by the quick charge.
The device should take about an hour an a half to fully charge, is it taking longer than that to fully charge?
