[Q] Charging of HOX+ problems - unable to top battery while actively using phone - HTC One X+

Did anyone try to use HOX+ in car as navigation? I have quite strong charger in car made for iPad (2.1A rated USB) and it is not able to charge phone when it is running navigation (Sygic, but it doesnt matter). It seems to me, that charging current is too low to charge battery and also power phone, which is actively used. Tried to repeat at home, again big Apple USB charger from iPad rated 2.1A and while I was actively using phone (browsing etc), charger was able to get 1% of battery charged per 15-20 minutes. Which is too long.
Phone is getting warm or even hot while using CPU actively (Chrome is able to run all 4 cores while rendering page) and maybe there is some protection to avoid HOX+ getting too hot while charging? Or maybe internal logic just doesnt take more juice from charger when phone is charging and being actively used (to power CPU/GPU and also charge battery)? Anyway result is that with intensive CPU/GPU apps like navigation, I cant charge phone fast enough and it is actually discharging! No matter how strong or good your charger is, phone takes constant current and sometimes its just not enoug...
Anyone got similar problems?

The problem is that you shouldn't use chargers meant for other electronic devices.
How is it with the charger supplied with the X+?
Bbattery Monitor Widget is good to track charge/discharge value.
I have not noticed anything out of the ordinary, even using the phone while it is charging.

And what is the difference between chargers with USB ports? I could understand that using cheap noname charger from China could be problem, but I'm using branded from Apple, which is known to be really well made. And it is providing 5V and up to 2.1A of current.
Anyway cant use original because I bought phone in UK and they have some ugly shaped power plugs unlike rest of Europe

...but it ain't working, obviously. A power adapter is like a couple of €s, and @amazon original charger are around 7 €

I've used both an OEM US charger and the UK charger with an adapter with the OEM cable and both have done fine. It does take longer to charge while using it, but that's no surprise.

The Apple charger should do better.
Simply put, the device reduces charge rate if the device gets too warm. I don't know if this is happening but it's something to keep in mind.

I had this issue also when i was using the device. Charging was stuck at 99% and did not change anymore.

Well, you probably can't top the battery while charging because the phone is drawing more current than what the charging circuit (internal to the phone) is able to deliver to the battery (while charging).

Been digging in this problem a little bit more and found strange pattern. Since I cant use original charger (UK version doesnt fit my outlet), I have to charge with Apple ones. I have one big for iPad3 (strong marked as 2.1A), one small one with 1A and one small one chinese copy from DX (also 1A). When I try to charge phone with first two, it just charge like USB (settings>power and there you can see type of chargin on the top of screen). When I use chinese copy, it charges like proper AC adapter, quite fast. But after while, touch screen is messed up and it is almost impossible to control my phone. It seems like some static electricity build up or something like this messing with toucscreen mechanism. It gets fine few seconds after removing phone from charger.
Tried different cables, have 3 types at home. Original cca 1m long, only chinese charger woks in AC mode. Then I have extra short for drive, same behavior like original and two long ones (2m), chinese from DX but well made with quite thick cable and with this even chinese sometimes charge like USB, but sometimes it connects like AC.
Always thought that Apple chargers are good and used them to charge other gadgets, never had any similar problems. Seems that One X+ is quite picky with chargers, anyone can verify if it is just my piece?

Car Chargers not charging.

Hello,
I went through two car chargers and found out that they are not really charging, or if they are its very super slow. I also found the same thing happens when active sync is on. I know on kaiser there is an option that enables/disables charging, but no option exists on AP3.0. So, is there a trick to this or what ?
Thanks.
I have found that you need a specific charger for the Advantage to get anything above trickle charge. On an Advantage, trickle charge is not enough to charge the device whilst it is in use i.e. it will still discharge even if a little more slowly. I initially used an HP charger from another device with the Advantage in my car and this is exactly what happened. I got a proper one for the Advantage and the device charges without difficulty even with all the radios, GPS, etc. on. This proper charger was not HTC badged but was designed for the Advantage. I am sure it is something to do with clever circuitry in the device or the charger that switches charging to trickle if it doesn't recognise the device it is connected to.
Hope this helps.

I believe you need to make sure the charger puts out 1.5 Amps. Somebody know if this is correct? My Dell Axim needed that much to charge and run GPS.

Hi there,
I bought the charger in the following link:
http://www.easydevices.co.uk/pp/HTC_Accessories/HTC_Advantage/HTC_ADVANTAGE_CAR_CHARGER.html
Cheap, and worked perfectly. I also bought the car mount from here.
no wonder, why my phone seems never to charger
I just use an inverter and the normal adapter with mine Cost me £20 a couple of years ago, but means I can charge my ameo, laptop, phone, or any other device I choose using standard charger. Saved me loads in the long run
the designed charger for the Ameo is 1 amp, a usb car, charger will only be about 0.5 amp, this is probably why its slower. I can charge my niki no problem, but my ipaq and ameo take all day in the car. I think inverters are on special at maplin at the moment. probably a cheaper way for me to charge everything in the car.
I had this problem and bought the following charger, it works a treat !
http://cgi.ebay.co.uk/2-AMP-IN-CAR-...photoQQcmdZViewItemQQ_trksidZp1742.m153.l1262
sometimes if your charger is aftermarket it dosen't work. happens with me with mp3 playerz too
guys the charger has to be 2 amp and better for u to maintain a charge while running everything (gps, bluetooth, wifi) especially if u get hsdpa signal. Oh this is my first post ever from the Advantage.

I actually disagree, I can do all that while being plugged into a regular electric outlet and the output rating for that charger is 5V 1Amp. So a 1A Car charger will do just fine.

Hi
I Disagree, Because i have bought two car charger with 1Amp both did not worked. Then i bought a 2Amp car charger it worked perfectly.
Therefore i think it will need 2Amp car charger to charge and give power to GPS, Bluetooth, etc. 1Amp may charge your Athena but it need to switched off(put into standby)
Thanks
This question has been discussed before in this forum. Look at this thread.
Put special attention to post #5. It seems that HTC uses one pin of the mini-usb connector (it has 5 pins while standar usb connector need only 4) to differentiate between charger and sync.
If the charger does not have this pin configured correctly , the athena thinks that it is a connection form a PC and does not start the fast charging.
Other option is to use a special adaptor like the one from PPC Tech (PPC Techs HTC Advantage Lil Sync DUO Mini-5 USB Adapter avaliable on expansys), that allows you to enable fast charging with any charger (minimun 1A). I have used it successfully with several car chargers.
Reminds me of this discussion http://www.modaco.com/content/HTC-Typhoon-Variants-Typhoon-MoDaCo-com/115090/Car-Charger/
Still doesn't charge enough even w/ HTC charger
Yes. The pin configuration is different for the Athena. Yes, it needs higher amperage to charge. However, even when taking all these things into account, there's still a problem.
I bought the HTC car charger precisely to avoid the problem of undercharging / pin misconfiguration. Yet, I still have problems. Whenever I drive long distances (4 hrs +, vacation, etc.), I generally have the gps running along with bluetooth for my ear piece (in case of phone calls), and I have an mp3 player going for tunes (running off the MD). Since it's generally a bright, sunny day, I also have the screen at full brightness (otherwise you can't see it at all.) Even with the HTC charger which is listed as the one designed for the Athena, my unit will die within 4 hours.
I realize that this is alot of juice, but it still annoys me that the charger can't keep up with the unit it was designed for. I imagine it wouldn't last that long if I had the gprs and/or wifi (not that I'd have wifi going while I drive anyway) running, too.
My question is: Do you think it's the screen or the MD which is sucking up all the juice? I've taken to letting the screen shut off (an option on many mp3 players), if I'm on the freeway and don't need the gps for a while. But to be honest, I haven't taken any really long trips to test this approach.
BTW, it's not a problem with the charger. I've got 2 of them, and the same thing happens with both.

I don't have problem like yours. I always have my backlight adjusted to the brightest. I keep all my applications on MD (which means it's spinning most of the time). With GPS running and music playing, my device will give charged to the fullest and stay that way very very quickly. I use the standard HTC charger. Only thing is I don't use bluetooth, so I'm not sure how much this would influence it.
Don't know what the current is, but my Brodit Active mount charges my Athena quickly even with everything turned on- used mainly for Sat-Nav with screen on full bright/ no sleep during day.
Trickle charge from the PC USB takes forever!

Using non-verizon branded chargers

I have a ton of micro-USB chargers that I've used with my GNex and Evo3D with no issue. The only consideration I take into account is Amperage, and I toss the ones below 800 mAh. Last night I plugged into one thats around 850 mAh and left my phone to charge all night (at around 5%). When I woke up, the phone had completely discharged without any sort of recharge.
Since this isn't a Nexus phone, am I locked in to only using verizon branded chargers? Is there a way to defeat that with root?
I haven't had any issues with that as I use all different types. Maybe just try another or maybe it wasn't plugged in all the way.
What voltage is it rated at? It could be that or that the charger is bad somehow. I charge mine nightly with a .7A charger and it's always been full when I wake up (about 30-50% when I go to sleep).
I have the sprint note 2 but they are essentially the same phone so here is what Igot for you:
there is no "smart" element to any chargers in the market, so your phone shouldn't know the difference between Verizon brand and the devil's own brand
if you look at the stock charger it outputs 2 amps...the phone needs this and in my experience it needs at least 1 amp in order to charge instead of discharging slower
also there is a known issue with all note 2s that the cable will not sit snugly inside the port causing it to be a bad connection... just make sure you put it in hard (no pun intended) and it shouldn't be a problem

Yeah, if you take a close look at the micro-usb port, it is recessed a bit. Make sure you plug the cable in firmly.

I think this was likely the issue. The charger is rated at 1 Amp, and I tried it out again last night and it appeared to work for the few seconds I had it plugged in, so I must not have had it in there snugly.
So I just tested with the same charger, and when I plug it in, it beeps every half second and flashes between the charging/discharging symbol, and does not charge...

I don't remember where, but I remember reading about someone with this issue where they were using their phone as a gps while charging it and it died. Someone commented saying that the culprit was probably a faulty charger. Sounds like they were right.

I have seen this same thing with two Droid X's plugged into the same 2A charger. One phone would charge and the other would do exactly as you describe. It didn't do it all the time, it just depended on how low the battery levels were on each device. How much battery life do you have left when it does this? You may just need to use a higher amperage charger.
I have not received my Note II yet, but it sucks that I will most likely not be able to charge it while tethered (USB) to my laptop.
Based on the info I could find (kernel driver), the phone will accept up to 650mA of power, so anything over that should charge the phone at the same rate. Voltage shouldn't be an issue as it is charging via USB, which is 5V (+/- 5%). Unless someone has an amp probe to put on it, we can't tell if it is actually pulling more or less than what the driver specifies. And, as someone else stated, the phone can't tell if you're using a genuine Samsung cable and charger, or a $1.00 made in China cable/charger, as long as they both output the same voltage/amperage, the phone will never know the difference.
Based on what you said though, if the phone is constantly seeing the charger connect/disconnect, that would drain the battery even faster.

[Q] My charger buzzes... should/can I use another?

When plugged in, the charger included with my Optimus G buzzes. Audibly. It's pretty loud. At first I thought a fly was in my room, then I realized it was coming from my charger.
If I unplug it, it keeps buzzing for about ten seconds.
I have a Nexus 7 charger and a Atrix 2 charger. Neither have the same specifications as the buzzing LG charger. The N7 outputs 2 amps, the Atrix outputs 0.85 amps, the LG outputs 1 amp.
So... is it safer to a) use the buzzing charger or b) use a non-buzzing charger, but one that outputs a higher/lower current than the included charger?
I'm now afraid to charge my phone.
Anyone else having a problem where the charger buzzes?
Thanks.
UPDATE so apparently some googling tells me that it IS okay to use other chargers AS LONG as the voltages are the same. Amps can vary; even if the charger is rated for more amps, the device will only take as much as it needs, and if the amps are lower than the device specifications, it will just charge more slowly.
So my N7 charger has the same voltage but higher amps, so I'm just using that until LG sends me a non-buzzing charger (if they ever return my request)
If any of this information about volts/amps is wrong, someone let me know. But it seems right according to my limited knowledge of physics.

Never seen that before. Had a lot of phones with a lot of chargers and never heard a buzz, I'd get a new one just to be safe...but I tend to be super cautious
Weird, my charger (that I got with the OG) buzzes as well. I've been using since I got it and it hasn't exploded....yet.

Interesting... so it's not an isolated issue. My phone is four days old, which is why it's frightening me. I think I'm just gonna submit a replacement request, and keep using the buzzing one until that one arrives (assuming it's granted and I don't have to deal with any bull from LG). If it's a common thing for the charger to buzz and yet no one is complaining about an exploding battery... it's probably safe.
But I'll request a replacement just to be safe.
My htc inspire charger has always buzzed when plugged in to the wall but not charging the phone. My guess is it is a function of the transformers magnetic field and some metal part in the charger.
My charger buzzes too, when is plugged in and for a few seconds after like you described. I've been using it since launch day on this phone with no issues. The buzz has not gotten any louder or anything over the past few months so I wouldn't worry about it.
Running SnowJB
Switching power supplies like our chargers sometimes do buzz because of the way they work, and it may or may not be an issue. Usually it's an inductor vibrating, and it may last as long as you need it to, or the vibration may cause eventual failure), but since yours is still under warranty I'd definitely replace it.
Using any other USB charger will not be dangerous or bad for your phone since the voltage is standard. If it's rated for a higher current, great - the phone will only draw as much as it is designed to, so you can't damage anything that way. Battery monitor widget appears to tell me that it only charges with about 800mA of current (that is net; the phone is still using some additional current to operate), so assuming the correct current is being reported, it doesn't appear that there's any benefit from using a charger that can supply more than 1A. Unless it can draw more quickly when charged with power off -- I don't have any good way to check this.
On the other side, while you can use a charger that's only rated for 500mA, which is the old USB standard current, the phone will charge more slowly and you'll probably get the warning saying so. It may not actually even supply enough current to charge the phone while you're using it in that case. So while you'll get by in a pinch for an overnight charge with one of those, it's well worth investing a couple of bucks in a higher-rated one.
I normally use my kindle fire charger which is rated for 1.9A (and the Fire can draw that much) or my New Trent battery pack which is rated for 2.1. My LG charger stays at work and doesn't get much use. I'm going to eventually buy another charger for home and I'll be looking for one rated for 2A or so.
Beeping
My charger is beeping after the battery is full. Its very very quiet but I hear a rhythmic beeping.

HOX+ seems to take forever to charge!

Hi everyone,
I have just swapped my Galaxy S3 to a HTC One X+ because I couldn't stand Samsung's Touchwiz, and I love Sense 5. The downside is the charging times on this new phone are pretty laughable!
Now I know different cables can give different currents consistently, but I have three cables (one at work, one in car, one at home) that would all deliver 1000mA to my GS3 and I could go from 10% to 100% in about 90 minutes, about 1% per minute, it was great! Battery life on this phone never degraded so I know 1000mA wasn't damaging at all (all GS3s can take a maximum of 1A).
I've now moved over to the HOX+ and it's taking absolutely forever to charge, between 3-4 hours to charge from low. I simply can't wait this long, it's beyond a joke :crying: I've checked Better Battery Stats and my battery usage is about the same as my GS3 when unplugged (about 4-5% per hour) which is fine, so why the difference in charging times?
On my GS3 I had an app which showed me charging current that was specific to GS3s and was very reliable, but I can't seem to find a reliable app for the HOX+, the one I have is Battery Monitor Widget and it reckons I'm charging @ 330mA and I'm currently at 22%, that can't be right can it?
Here is what my phone is says when charging "Charging (USB)".
In the past hour it's done about 20%.

Erm thats the issue. When you charge using the AC (By cable to the electric socket) it says "Charging(AC)" . This usually takes me from 10-100% in about 90 minutes with the HOX+.
Somehow either you are connecting it to a usb hub (laptop or a computer) which is pretty slow compared to the AC, or your phone is mixing up the AC and USB currents. So an advice, use an electric socket and make sure it says "AC" in the power tab. IF so, check the charging time you should find it similar to that of Samsung.
I also think usb 3.0 is faster in charging than 2.0 ? If you are on a new pc with a new motherboard you should find your sockets 3.0, so don't use a usb hub especially if it says usb 2.0 since it will be pretty slow.
Hi Gand0ur, thanks for the advice.
I should have said before; I never charge via a computer/laptop/USB hub. Only directly into the wall. It is an aftermarket charger but it's a good quality one as it charged my GS3 @ 1A and also my old Sensation charged in about 90 mins.
I've just tried a different cable and still the same outcome. I'll try another wall plug when I get home tonight

That isn't necessarily true. This charger has been the fastest thing to ever charge my HTC Sensation and GS3, and come to think of it my Nexus 7 charges faster with this charger too. As I said earlier, I had an app on the GS3 which showed it was outputting 1000mA (maximum the GS3 allows) and it would charge that phone in around 90 mins. According to the HOX+ app I have I'm only getting 330mA. Whilst I agree that poorer after-market chargers often give dubious results I'm confident that this isn't the charger's fault.
I'll try the a HTC charger when I get home, but the other night I had it on charge with the HTC charger and it didn't seem to move very quickly.
I'll just say what I know from experience with my HOX+: it only seems to be charging in a normal (and pretty fast) way with the original, from the box, charger.
I tried charging it with the charger from a Desire Z - slow; charger from Desire S - slow; a Nokia charger - slow.
I also noticed that while the Desire S or Z can get charged while being used, when using a car charger (a Nokia one), the HOX+ seems to be using more current, and it ultimately dies. It happened this summer, so this might be an issue.

I think you're right! I tried my wife's HTC One S charger last night (because the HOX+ doesn't come with one) and it changed to Charging (AC) for the first time. I have to say this is a massive let down for me, my car charger saved me so many times with my GS3 (for example I drove to Scotland and used GPS all the way, and the phone still charged right up at the same time) I'm not sure I can handle it not being able to cope with other chargers.
I find this extremely frustrating Is there not a hack to get around this with root?
I'm not sure about the Samsung, but the HTC will only go into the fast/AC Charging mode when it see the Data+ and Date- signals shorted on the USB port. This can be designed into the charger, such as the factory HTC wall charger, or you can buy "charging only" cables and then use any USB charger to get your HTC to go into AC charging mode. These charging only cables are tough to find, but amazon does sell them. Keep in mind that the charging only cables will not transfer data at Data+ and Data- are shorted. Once you are in AC charging mode, the phone takes over and determines how fast to charge. At low battery levels (less than 80% or so), the charging rate can be as high as 1000ma/h or the maximum the charger is rated to deliver. If the charger is rated to deliver more than 1000 ma/hr, the most your phone will draw is 1000 ma/hr.
Now there is another variable, the cable itself. Cheap cables sometimes have too much resistance to pass 1000ma/hr and can be the problem as well.
One other issue is the number of knock off chargers and cables out there. Beware of e_ay. You may not be getting what you think you are.
One final note, Apple designs the ipod to look for the Data+ and Data- signals to not be shorted (opposite of HTC and most android manufacturers). So chargers that are designed to charge Apple devices will need the Charging Only cables to charge android devices in the AC charging mode.
So if I didn't confuse myself, hopefully this will answering some charging questions. I've researched this and have tested many chargers and cables.

[Q] Unable to charge while turned on, only original charger works while turned off...

Hello XDA,
I'm not sure how this happened, but for the past couple of months I haven't been able to charge my phone while it is turned on. It shows the charging animation but the battery still drains, even with all radios off and screen off. I can leave it charging all night and end up with a nearly flat battery. Plugging it in to any wall socket seems to only slow the draining, and plugging it in to a fully powered USB socket (many tried) keeps it at the same battery level, or very slowly charges it if I don't use it. If I turn it off however, I can charge it until full in the normal time with the original AC charger.
Here's the really strange part: I've tried several new chargers of different brands including samsung and it makes no difference. Not only that, but they won't charge it when powered off either making them completely ineffective. It doesn't initialize the charge properly - the screen either shows a battery with a progress circle over and over again without getting to the charging animation, or displays the charging animation over and over and never charges at all, but nevertheless gets hot.
The chargers I've tried are:
Cygnet for samsung phones including SGS-II
Belkin for Samsung phones including SGS-II
Premium blackberry travel charger
Premium 10W 2A Samsung travel adaptor
One charger that did seem to work while plugged in was from a new Sony Xperia Windows phone charger I borrowed once.
I've exchanged at the store 3 times now with the same result! It must be something wrong with the hardware or software...
I've calibrated the battery, I've had a new battery for a couple of months and normally still lasts all day and more on a full charge. It is a 3rd party high quality Anker battery. The problem is the battery is getting a lot more taxed now that I'm using 3G over the portable hotspot, so its not quite lasting the day anymore.
I've had countless custom ROMs on there now, current ROM is CyanogenMod 10.1 stable. Would returning to stock then reinstalling help?
Something that shouldn't matter is I've moved from the UK to Australia. I'm still using the English charger as its the only one that works. And the Xperia charger that seemed to work was Australian too.
Before it got this bad I think it was getting slower and slower to charge. I had to replace the old USB cable that eventually got really loose, then broke and i've tried several new ones with no improvement in charging ability. Is it possible that the contacts inside the micro-USB socket might have been bent from the old cable moving around so much so that only minimal contact is achieved with any other cable? The new connectors do seem to fit perfectly.
In the attached screenshot, you will see on the left the AC charger is plugged in while battery level goes down, then on the far right its plugged in to a computer and is kept level.
Any suggestions would be greatly appreciated!!

Hello XDA,
I'm not sure how this happened, but for the past couple of months I haven't been able to charge my phone while it is turned on. It shows the charging animation but the battery still drains, even with all radios off and screen off. I can leave it charging all night and end up with a nearly flat battery. Plugging it in to any wall socket seems to only slow the draining, and plugging it in to a fully powered USB socket (many tried) keeps it at the same battery level, or very slowly charges it if I don't use it. If I turn it off however, I can charge it until full in the normal time with the original AC charger.

IMO, u should revert back to a stock samsung Firmware (pertained to ur region) and then see if the issue persists or not to rule out any possible 'Software issue' in the first place
Thank you, I will try that and report back the results.
You can try hawkerpauls nuke if flashing stock doesn't work: http://forum.xda-developers.com/showthread.php?t=2100558
