Hey! Guys I am having problems with the USB Charging, it seems to drain the 100% charged battery quicker (while using the phone, unplugged NOT charging) like one day and I have to charge the phone again, But when i charge my phone (100% charge) using the wall charger my phone lasts two and a half days. My wife also said she experiences the same thing with USB charged HTC Trinity Phone. I have tried on different computers and laptops as well but still the same and i know that USB charging will take longer to charge (500mah) so i leave the phone over night like 9 hours but the phone drains like juice. What kind of a Phenomenon is this.. Guys i need your humble thoughts and solutions on this because this is becoming a big problem for me since i use USB charging mostly... Plus I am not a very hardcore app, wifi or games user on the phone either... Darn...
same problem
I don't know why but i meting with the same problem. No idea why this happening it should be same from electric perspective.
When the phone cahrges via computer USB, the phone charges at a rate of around 90mA due to the phone running. Try with the phone off
Tried that as well, but it seems to be the quite the same but little difference since it last a little longer but still drained out in one freakin day. I am pulling my hair off because of this problem.. darn why is this just so... i mean like in the second post the process should be electronically identical right. only difference is it takes more time to charge from USB.... Grrrrr!
my phone hardly last one day..How do you make it last for 2 1/2 days?

Battery indicators do lie.
it all depends upon if your board can deliver enough current to run the phone and charge it. on my rig i see no difference between wall charger and laptop or desktop charging
the laptop is a studio 15 with an i5 and h55 chipset and the desktop is a core 2d machine with a p45 series chipset.
you can tell the phone to disable usb charging if the phone is on while connected to usb to see if that helps (it will still charge via USB if the phone is off)

any usb not from china will give about 500mah, whether it be my i7 laptop or z550 vaio, so specific components shouldn't matter.
usb charges a little slower, but no reason it should not last as long once its got all the amps it can take. weird situation man...my huge list of htc phones never had an issue, and i do use a work computer to charge via usb sometimes
Thanks for your thoughts guys!!!
Weird... Yeah thats the thing i am also using a Core i7 930 CPU and my motherboard is ASUS ROG Rampage III Gene board, so i don't think my system is the problem here...
The wall charger delives 2 amperes to our HTC phones while usb ports delivery only 500mA (0,5 amperes). It's not only a matter of charging slower but you can't deliver the full charge the battery needs to revert the chemical process of discharging when tou use usb port. With 2amperes the charging process reachs it's maximum.

some cheap mainboards cannot supply even 500ma. a good qaulity board can supply more.
want to test it? put your HD2 in the first USB port and then put a high power device like a wireless dongle or external USB HDD in the second and see what happens. if your board cannot power both, you'll drop your wireless/hdd connection when you plug your phone in.

Sir I have said that I am not a very heavy phone using guy, I am an average phone user. Plus I dont use the 3g or data connection here in my country since the connections are snail slow and prices are over the head and there is no unlimited data package here yet. I use the Wifi sometimes to update my twitter, Rss hub, facebook, weather tabs and very little market place... So my phone lasts for two and a half days when i use the wall charger.
Oh yeah and Guys, i tried recalibrating the battery by using it till the phone died completely and recharging it with USB (phone turned off) for like a day but still it drains faster than the wall charger rate.... I dont understand really...

This is why. The awnser was given, but people ignored it. To fully charge a battery it needs more amperes. Use the wall charger. The battery indicator lies, and is unable to acuratly measure a fully charged battery. It'll display 100% when it's roughly 70%.
Our batteries use Lithium ions as means of electricity. They use a Lithium compound, and move the ions from the negative to the positive pole. When there are no more ions to move, our batteries are discharged. When we connect to an external power source, the higher voltage will draw the ions back to the "negative pole".
USB supplies 500 mA (that's 0.5A) @ 5V (per specification, some motherboards won't be able to go that high, depending number of USB devices connected, etc)
European electrical sockets supply up to 2.5A @ 230V and although your HTC charger should only output 1A @ 5V, the topping off will occur much quicker.
Basically the more you have to charge, the more time it takes, and the bigger the effort on the current to pull the remaining ions back to the negative pole.
I am finding that in Android, my phone will not charge with either wall or usb charging. The phone shows that it is charging but does not actually charge. This is really unacceptable. It works in Windows Mobile but is not a listed problem of the Android builds. Are all of you using WM6.5 or Android? Or both?

I can Charge my HD2 well on both OS's but still when compared to android and WinMo when i use the USB Android does discharge heavily than WinMO and Android does the same when compared to WinMO on wall charger use as well... So nothing much more to say at that...
Charging mobiles using USB takes alot longer than using power outlet and this is valid for all kind of mobiles, ALSO when you charge by USB your mobiles battery drains much faster than charging from power outlet. (Electrical Engineers say so).
NOW why you don't use power outlet to charge your HD2 rather than using USB?
There are safety measures in charging from USB like, static issues from wall charger in some countries and then there is the ease of use from charging from PC while you are at work or away on a business trip..

Mine lives for 5 days on just 1 charge, and with normal use (every 2/3 hours updating weather and twitter, sometimes call, sometimes texting, sometimes using internet)
If I have the screen on while plugged in, my battery % continues to drop and the device itself feels kind of hot. Could I have a problem or is this normal?
My battery life has also not been so great.

Mine doesn't it keeps going up, though I haven't tried playing games. It does depend on what you are doing with the device, if you are running applications that max out the processor it will possibly drop.
The GSII would drain while plugged in if the screen was on. You would see a noticeable drain while using GPS and Music and driving. The only way to make it work was to turn the screen off on the device, the GSIII has a better charging chip in it, and it isn't limited to 650maH (from what I can tell since it is charging when using GPS)
I noticed it while using a usb car cigarette adapter as well as a usb port on my laptop. the car adapter is a 2 amp charger capable of charging a tablet. I will see how it performs with the oem wall charger.

Yeah I was charging my phone earlier using a car was adapter with the oem micro usb cable and they phone got very hot.
What do you guys think? Is this a cause for concern? Do I need to buy a manufacturer approved adapter?
Is it safe to leave the phone plugged in overnight? I usually charge the phone when I go to bed, but I've the this might damage some batteries.

I'm curious about this myself....I'm leaning towards not leaving mine plugged all night. I 2 have done this in the past with other phones and can't be certain but maybe this is a rEason I had horrible batt life despite efforts to Better it. So I'm gonna stick with charging/topping off when I can. Gonna start just charging when I wake up while I'm getting ready for work. I did notice that when battery is completely charged a message comes up telling u so and to unplug. So I'm gonna follow directions haha.

All modern smartphones have chips that control power, and cycle charging appropriately to not abuse the battery. Many phones monitor the temp of the battery and such to ensure a good and safe charge. You can leave it plugged in overnight just fine..
It definitely doesn't like 3rd party adapters. I'm hoping it will at least accept the tab adapter with samsung's cable so that I can charge it at work without buying a dozen chargers, but...
(One charger I used is understandable - turns out its only 300ma. Whoops! But using full 1A chargers wasn't helping either, it went up maybe 1% every 15 mins. The stock charger ran it up fast enough that it was charged from 70% in under an hour.)
I use SetCPU and have a setting to reduce the clock when it exceeds a temperate parameter. You could also set a max clock for when it is plugged into a USB (Computer/Car charger). That could help it stay cooler and charge faster while not plugged into the wall.
I charged from empty to full this morning when plugged into the wall in about 3 hours. I haven't tested on my computer yet.
I went through this when I first got my Evo 4G. I did not realize at the time that the 500mA charger I was using with my Blackberry Storm (horrible device) would not charge my Evo while doing anything power intensive (like using GPS) and I quickly drained it on a car trip.
I went on Amazon and bought a $20 Schosche iPad charger that claimed to provide 2.1A which should be plenty. On that charger the phone would charge while using GPS but very, very slowly.
After some more research I found that some chargers caused the phone to switch into "USB" charging mode and others would switch it to "AC" mode which would draw much more power and charge faster.
This is the charger I ended up with and it works great:
http://www.monoprice.com/products/p...=10826&cs_id=1082602&p_id=6766&seq=1&format=2
My Evo charges just as fast as it does on the OEM wall charger. I don't have my SIII yet (thanks Verizon for being the LAST in the US to ship them out...) so I can't yet say if this holds true for the SIII but I assume it will. At $1.22 it's not much of a gamble.
I've noticed a massive difference when using the mains charger compared to using a USB port on a PC, the former charges the phone really quickly, the latter barely charges the phone at all. Has anyone else found this too? If so is there anything I can do to improve the charge rate? I'd rather not have to get a second charger at work, just in case I forget to charge the phone overnight

That is actually intentional. If the phone recognizes the connection as USB to a PC or car stereo it only charges at 1000ma as that is the max current most of these devices can provide. The stock charger provides 2 amps. You can pick up an inexpensive charger and USB on Monoprice or Amazon that will charge your phone much faster.
Hello there developers,not sure if I'm posting on the right place but I have a really big problem. My new Pogo Cable arrived and I was so excited to use it,but my happiness didn't lasted fort too long. The problem is that the Tablet while charging with the Pogo cable is either charging slow ,or neither at all. This issue is available for both Lollipop and Kit-Kat,have upgraded an then downgraded with the hope that the issue will be solved. The original Micro -Usb cable works good but with the Pogo Cable in the Battery Monitor Widget it appears "Discharging" and "AC Plugged",and the charging rate is booring slow. Had the idea to measure the Voltage and the current Flow with a multimeter and got the surprise that while the voltage is 5.12 V the amperage is 0.12 A ,while the original charger pumps up to 2 Amps. Could this be the issue? Is there some electrical switch that should open and release all those 2 Amps or is this Cable a Hoax or something that is not fully functional? Thanks in advance,hope that you guys will enlight me somehow!
I've no idea if this is related but be aware that having your pogo plug connected while also having anything connected to the microUSB will stop charging. The charging icon (lightning bolt) will still appear but that I'd a false indicator. This limitation is due to the Android kernel and is present in all versions of Android.
I exclusively use a pogo plug to charge my Nexus 10 and it has always worked on all versions of Android including 5.0.2 which I'm on today. For me pogo plug charging has always been about 25 percent faster then USB charging.

My experience is exactly the same as 3DSammy reports.
well my warranty is expired so i Decided to "surgically" dissmantle my Nexus 10 in a heroic attempt to find the cause and I have made a breakthrough (or at least I tought so). I got another Pogo cable ,and this one was good,the voltage was exactly 5 Volts measured and the Amperage that I got was 2.21 Amps measured with a 6 Ohm fuse,all these values where from the original Samsung charger. All things good,but the Tablet is still not charging at all,the same Lightning animations and even after 3~4 hours still no charge at all,and this is Lame in my opinion. So after opening the tablet,I got the idea to short the 3 and 4 pogo pins together,and assumed that this will draw all the power that the battery needs to charge,the idea was working i got 20% more power draw than the usb cable BUT for only let's say Half of hour ,and then the same old story,battery was discharging but the lightning animation was on. This is not so good and my suppose is that the Power Management iC from the motherboard is some how not managing the Pogo charge at all :laugh: so my next idea is to wire the charging Pogo pins directly to the battery and hope for the best. Regards! :good:

I've got one of the original n10 from first day of issue. My battery is going to hell after being used and charged every day for the past couple years. It's been on/run everyday since Dec. 2012. I have always had a problem charging while using it. My display is always set at about 1/3 bright. When my battery drops to critical, I plug in the pogo and usually put it in sleep mode to charge. It will quick charge that way.
If I still need to use it at critical battery level, plugged into the pogo plug, it maintains power and possibly gives it a very slow increase in charge. Almost none noticeable, but will maintain power level (unless tons of graphic, camera or movies along with full bright screen).
I've just taken it for granted that this is how it works. Pogo plug will maintain battery while using and will switch to quick charge once put into sleep mode or powered off. It's always acted that way, so I have never known anything different.

Well I'm sure about what did you said,but in my opinion this is a marketing bulls$h*t. Why would I use that Pogo cable if it's role is to charge only on sleep mode and powered off?I ordered because I thought that like the instructions of the pogo says:" it will charge the battery even when you are using it for movies and browsing,being more handy ,because you have the micro USB port free." I play games ,I surf the web,so my tablet is hooked up to a USB hub so I have connected a mouse,a keyboard and a game controller,so my USB port is full,and I hoped the pogo will help. Charging only on sleep is equal to zero for me,I need live charging,in the same time as the tablet runs games and other stuff. In my opinion this "glitch" should have been told on the pogo site,so I could full understand this cable and it's role. Shame on Samsung,30$ .for nothing! Thanks for the help!
Like a lot of people I charge my phone over night, but with the 6p I wake up in the morning (after a good 8hrs) and its sat on 96-98%. Even though it still says charging.
It's no big deal but when I unplug and plug back in it charges to 100% relatively quickly.
Anyone else see this? I'm using an older charger (from my nexus 4) so may try the proper one tonight.

Isn't this normal behaviour? Most phones stop topping up the battery even when connected on the charger to avoid wearing off the battery.
I used to have my HTC m7 connected overnight to the charger and even though it showed 100℅ in the morning, as soon as I disconnected it from the main the indictor would drop rapidly to ~95℅ which indicated the above behaviour.

I've not seen it before. My galaxy s6 always came off charge at 100% as did my nexus4 and the 5x I owned briefly.
If this is normal and happens to other 6p owners I'm happy with that

Mine is doing this as well. It seems to charge to 100%, stop charging, and not run off power at all. Since I use sleep tracking, in my case, I usually wake up to about a 90% charge. This is the first phone I have seen do this -- they usually charge to 100% and keep running off the charger. I haven't tried the stock 3A charger yet, as there really is no need for a quick charge overnight.

How in the world are you using an old charger on a Type-C Connection? (or are you using a converter?... if so, that may be the reason)
Just using a USB A to USB C cable into the power brick from my old phone.
Pretty straightforward really.
I'll try with the proper charger at some point. It's not a big deal.
Mine hasn't done that. Got it Thursday and it's had a full charge each morning. Using the supplied charger
normal behavior. it does that to protect the battery.
Every phone I've ever had charges to 100% and stays running off the charger to stay at 100%. Last night (my first night with the phone) I plugged it in with 31% and woke up with it at 81%. It clearly charged....and then stopped charging only to run off the battery while still plugged in. Not normal for any other device I've owned. I would prefer it to stay at 100% until I'm ready to unplug it. Maybe using the supplied charger will do this. I used a USB A to C cable plugged into USB wall port. I have replaced several outlets in my house to ones with built in 2.1A USB chargers.

Why should it matter? wattage is wattage. Does the phone charge differently with the stock charger? Do you always carry it in your back pocket? Do you ever use a car charger?

Carry the phone in my back pocket? No, I don't but what does that have to do with the price of tea in China? I do not use a car charger either. As for wattage, I believe that the type C 3.1 chargers output at 100W and possibly 200W whereas the one you are using might deliver 18W. There might also be damage due to wiring with some of the 2.0 - 3.1 adapters but I'm still researching that.
So why wouldn't you use the type C charger? Besides, you can't plug it in backwards or upside down. And once you get a computer that supports type C the data transfer rates will be astonishing from what I've read.

Do you carry STOCK charger in your back pocket.
Point is, sometimes I need to charge it at work, or elsewhere as I may use it heavily. That's why I would use another charger. Point is, why does it stop charging on the charger and not draw from the charger once it's full. Like I said, mine charged fully then stopped using the charger drawing from the battery. Kind of pointless if I leave it on the charger to be full when I leave in the morning if it's not going to be full.
I'm glad its not just me who finds this a bit odd.
I used the same charger with my nexus 5x, galaxy s6 and nexus 4 and always found the phone at 100% in the morning.
The 6p obviously works differently.

I see what you mean. For a quick boost charge I can see you carrying a cord in your back pocket. I'm really trying to get a full 14-18 hours with this device no matter my usage. If I can't I really cannot justify this expense. I have 4 phones on my plan, a Samsung 5S, two iPhones 6s, and up until yesterday my N5. All other 3 got a full day plus even watching video and listening to music constantly. So no, I'm not carrying a charger, a cord or buying a car charger.
As for your problem of charging, have you tried the stock charger to see if you can get to 100%. I have already twice with no problem. Last night I wanted to unplug it once charged to see how much it drained overnight but I fell asleep at 93% and unplugged a few hours later. 6 hours off the charger it was still at 99% so I'm assuming it charged to 100 or close to it. Perhaps you can do a full charge overnight and then a spot charge during the day if you need. I'm thinking you might not.
I am also having this problem. I am using the included c to a cable to charge with. The phone stops charging around 95% and doesn't charge ever again until I unplug it and plug it back in.
These are the problems with this:
1. Cases where i do not have the included charger with me.
2. On long trips where my phone is plugged in all the time to prevent it from dying. (Streaming music, navigating, etc)
3. Sleep tracking
I'm using the Anker 5 port charging hub at 2A each port.
once your battery gets fully charged 100% - the charging stops to prevent your battery from overcharging. since your battery is not charging - your battery will drop down. once it gets down to 95% - charging resumes until it gets back to 100%.
in other words - that is normal.

Every other phone I have ever had did not do this and instead trickle charged at 100% and ran everything off of the charging port, never had a phone that constantly drops to 95% then back to 100%, that would be a roller coaster during car trips. The problem I'm experiencing is not that situation either; the phone will stop charging and never get charged again, so it could drop to 80% while connected to the charger. It knows it's connected to a charger, but doesn't draw current from it. Doesn't show the charging icon or charging AC, but the lock screen shows the percentage of battery.
I do have possibly some positive observations however. Last night I decided to try it without my USB 3.0 extension cable, and only the measly 1 foot c to a cable Google provided. Without the extension cable my phone charged as it should, went to 100% and stayed there with the charging symbol still on the battery icon. Upon removal of the charger, the battery stats showed only 3 seconds of use, whereas before it would just show everything since last 100% (which was sometimes 50 hours even though i charge my phone every night). I'd have to keep observing this to see if it was indeed the extension cable.
That's interesting wrt the extension cable. I have a extension as well. Will get rid and see what happens. I keep meaning to try stock charger and stock cable but can't be bothered.
It's not normal behaviour or else it'd happen on other phones. I've had nexus 4 iPhone 4s htc one m8 Samsung galaxy s6 iPhone 5s and nexus 5x all using the same charger / extension all have charged to 100% and stayed there.. Except the 6p.
It's not a massive deal, typically it'll loose 1 or 2 percent over night once it's been to 100.
Just an update, it was the extension cable. Phone charges to 100 at stays there until unplugged as is expected behavior. Just don't use USB extension cables to charge devices
