[Q] Strange battery issue [SOLVED]

I bought my HTC One X on 3rd April and did a full charge (100%) on day one. I think it took around 3 hours for the battery to get fully charged.
Since then the battery has been performing pretty well, giving me around 10 hours of no-charge time, with screen set at auto brightness, 3G and auto-sync ON, and nominal usage.
My charging cycle:
1) My phone battery is below 20% when I wake up, so I charge my phone in the morning before leaving for office, for almost 1 hour; this gives me a battery level of around 40%
2) With no charging on my way to office (which is a 15 minute drive from my place), I plug the phone to a wall charger on reaching office till the battery reaches 100%; this takes around 2 hours to complete; sometimes when I have to go for meetings and all, I pull out the charger and resume the charging once I'm back on my desk
3) I don't charge the phone again during the day
The problem:
Today in the morning, the battery showed a 2% level. (and I wasnt surprised because I watched some youtube videos before sleeping yesterday night and the battery level was 20% back then)
I plugged it in a wall charger; after a while I notice a message on the screen...something like: 'Your phone is using more power than being supplied by charger. Please close some applications blah blah' So I flicked-off a couple of 'Recent Apps'. The battery still read 2%
After 1 hour, I saw the battery had reached 4% only; so I thought I better power off my phone and let the phone charge with no power being consumed.
But to my surprise, when I turned on the phone after 1 hour.....the battery still read 4%!!!
My phone's constantly plugged in since morning (8 am) and till now, (10.30 pm) the battery has reached 40% level only, with no phone usage at all.
One clear problem: The phone is not getting charged while it is off (although the red LED is glowing). And the battery level is taking ages to go up.
I'm using the stock ROM, no rooting.
Is there anyone who has faced anything similar.
I would also like to know is there any graphic or some symbol on the screen when you try to charge the phone while it is turned OFF?? My phone only shows the red LED glowing.
Please help.

Unfortunately there is no way of monitoring how much your phone is charging while off... I remember I've had a battery drain once and it only charged 20% in like 4hrs, which is not as bad as the problem you have, but still not ok.
What I did was: hard shutdown (holding down the power button) the boot, turned off normally and plugged it in while off. It took another 3hrs for the green led to show up (was at about 40%), but I gave it one more hour to make sure it's really 100%. That fixed the issue for me.
Anyway, if your phone doesn't charge when off, there's definitely something wrong and you should return it...
Even though LiPoly batteries are supposed to have no memory effect, it's recommended you charge it to 100% and use it to about 8% for the first couple if circles. Did you do that?
If you were rooted I'd recommend to wipe battery stats, but I guess that's not an option as you might want to return it...
EDIT: could you post a screenshot of the battery graph? (Settings->Power->Usage)

Thanks a lot buddy

Hard shutdown worked!!!
I just did as you suggested...and it worked...my battery shows 80% level now...plugging it for charging now...would keep you posted on the progress ...
Now I realise where the problem was...
On the battery usage screen , it showed "18 hours on battery"...whereas it was being charged ...I think the battery usage app/function was stuck...

Thanks again

I'm not sure why, but I only see a little black box when opening your screenshot.
The battery app isn't literally stuck. That happens when you:
turn off your phone -> charge it -> unplug it -> boot it.
Another reboot will usually solve this problem.

HOX drains more than charger is giving
I think it will be a good place to post it. Last week I was testing GPS on HOX. I was very disappointed when I saw that my battery is draining despite of connected car charger ( some kind of cheap chinese usb chargers ). My settings Autobrightness ON, Autosync ON, Data 3G ON on AHRD 5.1. Oh and I was testing Google Navigation. Does anyone have similar problem? I don't know if it is fault charger or HOX need so much energy when navigating.

It happens with most of us. Because, the screen takes more power sometimes more than the power provided by a car charger. Reduce the brightness of screen instead of AUTO brightness. It should help.

Battery Problem (Charging and Draining)

I got my Note 10.1 2014 Edition yesterday. I noticed out of the box that it was draining extremely fast. When I put it on the charger, it charged very slow.
I put the tablet on the charger while I slept (6hrs), the tablet did not even charge fully. Only to 88%.
Anyone have battery drain or slow charging issues?

it's possible you have a bum unit. are you using the supplied charger and cable? some cables aren't high enough quality to sustain the higher charge rate and of course some chargers don't output enough power.

Yes, I am using the 2 AMP charger. I have it fully charged now. I am going to test it for the next day or so and it see how it performs. I will report back.

Mine also seems to charge really slow and drain way faster than my 2012 model. I noticed that the AC adapter gets really hot. I've tried with two USB cables and no such luck in improving anything. I don't know what's going on here. I need to some objective comparison testing but this just doesn't feel right to me.
I couldn't get to 100% on the initial charge until after I turned it on. It kind of just hung there in that 88% area.

so far I'm at 1 day 6.5 hrs with 5.25hrs screen and at 38%. not ag good as the old note, but the old gn101 wwasn't as purdy!

Charging and drain
Mine took a charge over night but the battery drains fast. I noticed that the auto brightness is set way too low. Perhaps that's how they got the claimed hours of use.

It does charge pretty slow, I'm surprised they didn't include a micro usb 3.0 like the note 3. I noticed last night that when I was plugged in to the included charger and streaming a video from chrome, it actually drained battery rather than charged. Even using it with lighter tasks significantly slows down charging, making it almost a requirement to charge it overnight.
It drains relatively quickly but if i can get 6+ hours of screen on time, between that and my phone it should last me more than a day of heavy use.

until the battery drains to 80% it's at trickle/slow charge. below 80 it charges full power. mine took 3.5hrs from 20 to 100. it took 2hrs 20 min to go 20 to 80 then 1.5 hrs for the last 20%.

Charging and drain
I noticed it drains quickly for the first 15 or 20% but lasts much longer after that. So I can only think that it's not reading the charge evenly.

I experienced a similar issue today. Had it plugged in overnight and most of the morning. Went to unplug it earlier and it was frozen at 83%. That was after about 12 hours of charging. I plugged it in around 40% last night.
The first two nights charged to 100% fine.

when i first got the note it kept getting stuck at 64% but the next day i charged it completely.
this has definitely got to be the reason one of those reviews said it's 7hrs to full charge.
i haven't taken the update yet so i'm assuming the some of you guys have and it's not changed anything. i haven't had any issue yet, but i also haven't had a need to recharge yet.

Old thread, but I am running into two issues:
1. I agree on the drain, but will use for another week to see how things go. So far the battery drain is considerably more than the iPad 4 and Dell 5130.
2. I can not find a spare cable that will allow slow charge through a computer USB. Cables allow MTP, but there is an X on the charge symbol. I tried charging while asleep and when shut off and same result. Not charging.
One of the reasons I got this was not to have to rely on keeping the charger with me like some other Android tablets.

I have been facing constant battery drain for sometime now. Even while charging, battery keeps on draining without much of heavy use.
Plus it may sound weird, but this constant drain is not continuous for days. Some days battery works fine, but some days it just won't charge. For example, last night i kept my phone on charging, but in the morning battery was around 75% charged instead of 100% (charge time was around 7-8 hours)
I am using original charger supplied to me by this phone and the phone itself is unrooted/ stock rom.

Your battery sounds like it sucks.
I am using a method on my phone that shows me (about) how many mA is going in and out of the battery. An App called CoolTool amazingly loaded and complex app, which can do an overlay. I use this app for only One visual overlay, the mA display. (current)
I wont tell you how to set it up, because you will find it. I will tell you it shows how much power is being sucked up, and the reverse shows negative numbers when being charged , at least when being charged faster than it discharges. Set it to update every 30seconds, not a great update rate , but given enough time you can see what is going on. There is another program called "current widget" capable of faster updates, but does not do overlay (cause its a widget), It will work to show power on this here lg too, but i do not find it as usefull, and high update rates could take a bit more battery.
Speaking of charging faster than discharging, turn on the wifi and the screen and mabey some background garbage, then charge it up with either a lightweight wire (to much resistance) or a charger that does not have a good output. And it will use more power than you can put in So when charging on either of these apps that shows current, you eventually want to see actual Negative numbers like -1000 for a fast charge from the OEM charger.
So get a view going , and you can see what is happening. Not all the phones will show this current, and not very many programs do it, And with coolTool we also get to see it (overlay) when gaming, and watching movies. so it is a start to discovery. I have no affiliation with all these programs that i am ending up recommending, other than having been through google store hell for ages trying to find the right ones.

Thank you for the reply. Let me see if it helps
I appreciate your help, but i don't understand a word the app is trying to show me. I am currently using the app, and sometimes the charge goes up to 376mA down to -21mA while doing one time charge.
Is it normal? I don't have a spare charger to try it, but was using OEM charger. Stats i told was from the OEM itself.

So it probably is not your battery, it is probably the rate of charge.
This is a similar quantity that I will see when the "fast charge" is not going , there might even be a notification saying slow charge.
That happened to me 3 different ways.
1) when using a non-oem charger (including pc)
2) when using a different wire, the wires that did not work were either longer or weaker wiring.
3) just because fast charge did not kick in for some reason, disconnecting both sides and reconnecting worked.
I believe that the numbers your seeing , just like what i saw, are a 500mA type Charge rate, it is showing about 300mA (from the battery) when the phone (at least temporarily) is using about 800mA and the negative numbers (-21mA) when it is finnaly using less than the 500mA.
Turning the backlight down (a lot) and turning off ALL the other stuff that uses battery, can get the Use down to about 250mA , or turning it to screen off, where it should use very little.
Still without this fast charge, it isnt going to be a very happy experience, but it is possible to use.

Charger which i use
See the difference in charges and look at the time. (Note each time i took screenshot, i pulled the wall charger out of socket and put it back on. Shouldn't it be constant?)

That is the 1.2A charger, there is also a 1.8A charger.
I do not think that the cool tool has any averaging, it is just a single sample. So it would be all over the place as the use of the phone and charging changes, it will be More the same when the exact same things are done. the exact same screen lighting, the same ammount of cpu use etc for long times. So it can easily vary 500, or under much user control of the phone you can get it to stabalise with +-100 swings.
I have most all of the apps and background data, and Mobile data, and all that stuff under control. You also now have one more app (the cool tool itself) that will be using power. that is why i mentioned controlling it to only 1 thing.
So it is all very normal to see such changes in the sampling, I spent a lot of time getting samples, to get a feel for everything. I dont write them down, but I know what gets it to change now, some things more than others. (some I can do without
You should still be able to shut off most of your apps temporarily and turn off unnessisary I/O and features, lower the light, and wait , and wait to see how the charge is working.

Yep i have already tried and done from past weeks. Some days it just works fine, but other days, it just sucks. I mean looking at your phone with battery going down exponentially in front of your own eyes and you out at office.
But yes, I'll try a 1.8A charger in a few days. will get back to you then

[Q] Can Lollipop update cause these issues

Today I updated my galaxy tab S to 5.0.2 stock. I've had two issues with the update, by the way I'm using the LTE version, one is really slow charging like 10 to 15% an hour slow, And the other is at the fingerprint sensor keeps failing on me asking me to restart.I just keep tapping okay and eventually it will be back to normal really annoying an popping of these dialog boxes to go away I just keep tapping okay and eventually it will be back to normal. I'm not sure about the finger scanner BEFORE the update, but I can tell you I've never dropped it, while charging seemed to be at 25-30 an hour before. Normal or strange?

It sounds like you might need to recalibrate the battery, you can download free apps from the play store that delete the battery calibration data and then you do a full discharge and charge to make a new one, you need to be rooted.
There is a way to recalibrate without be rooted, but it has to be done manually just ask.
The calculation below are just a guess as i never fully charge my 10.5" and have now done about 170 days without restarting it, never since i got it.
I have the 10.5" and it has an 7900mah battery, and it charges at 1800ma till it hits 80% then it slows down, so using a battery charge time calculator it will take me 5H to go from 0% to 80%
If you have the 8.4" as it has an 4900mah battery, if it charges at 1800ma to 80% , it will take 3H to go from 0% to 80%
It`s the last 20% that take the longest to finish as the charge rate is reduce lower and lower till it hits 100%, so i only ever charge my 10.5" to 80% plus it`s better for the battery.
I use GSam Battery Monitor to sound an alarm when the charge hits 80%

I have the 10.5 and it's slow even on lower percent.. Been charging for 2h only gone up 10% from 3 to 12.

Definitely something wrong there.
Are you using the original charger and usb cable, as other chargers and cable can be really slow.
Try the app below, it should tell you your charging current, it should be around 1800ma

Samsung charger is broken, with an LG charger it shows max at 1800 mA, so there's the problem. Thanks!

Great that you have found your problem, did you fix the fingerprint sensor problem you were having?
Also that LG charger are you using, do you have the model number? , as it`s hard to find non Samsung chargers that charge fast.
Thanks
John.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the OnePlus X can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Administrators and Moderators!
Please take up the order in the old forums.

Well I don't need sugar+caffeine, but regarding the phone it takes at least 100 minute to charge from 1% to 100% on a power socket. On a USB port - I have not tried yet, but it could take double the time I guess.

Pretty crappy. This thing pulls about 1.2mA from the socket and therefore takes a while to charge up. Say about 2 hours to full from 10-15%.

Max amp draw I get. Same with a 10w USB charger or the one plus stock.

5% to 100% i only need 1 hour 40 minutes something. So its fine with me.

1.5 hours. Pretty fast

Better than Galaxy S3 (my former phone)

120 Minutes (2 Hours) from 5% to 100% for me.

90minutes from 0 to 100℅ which seems pretty fast to me as compared to other phones with "fast charge" which can take take 2h45m for full charge(4000mah)

Hi folks,
Last night, my oneplus X took almost 4 to 5 hours from 0 to 97% (not really 100%!). I noticed this degradation of charging since a couple of months, but i can not figure it out if it came from the battery or from the charger. I tried with another charger, and it takes almost the same time...
And also my battery seems to be less efficient, so i have to consider to replace it or there is another solution ?
Thanks

Well, this is an unfortunate tell of events. Onyx has a very very inaccurate fuelguager and it doesn't seem to adjust with time so as the battery degrades, it gets dramatically worse. I too have the sane issue and no matter what I do to circumvent this in my kernel sources, it always pops back up.
Point being, there really isn't a solution though I do soon hope to take a closer look at the fuelguager and rewrite bits of it in my kernel to improve its accuracy

I had the same issue. At some point charging became very slow. But if it's decharging at a normal rate, then it's not the battery.
In my case, getting the charging port repaired at a local phone repair shop did the trick. Now charging from 0 to 100% doesn't take 4 hours anymore, but again 1.5 to 2 hours.

enable USB fast charging in Kernel aduitor that also helps.
Keep mobile data off when charging that also speeds up charging.

Not sure if the phone is old. It seems slower to charge. 2 to 2.5 hours with no usage during charging.
Anyone face this?
On lineage 15.1 june build and usb fast charge enabled. Using stock charger.

Check charging rate with "Ampere" .
Then, try to unactivate USB debugging and check again (after plug / unplug).
