Charging time for my battery is pretty slow. I takes more than 3 hours from 10% to full! It doesn't matter if it is chraging with the carger or via USB. Is this normal with the Nexus? I had Htc Inspire 4G, and the charging took 2 hours top!
*if i use the phone while charging e.g. play some game, the battery is still draining instead of charging.

You should get better results with an A/C charger but I've seen some wall adapters still read as if its plugged in via USB. You can check by going to settings >> battery while it's plugged in and it should read A/C charging.

What is the max current (mA) the charger you use can provide? Divide the capacity of your battery (in mAh) by the charge current. That is your approximate charge time in hours. I believe most AC chargers can charge with 1A, so a stock GSM battery of 1750 mAh should take less than 2 hours from being discharged to fully charged. Mine does.
The behavior that the GNEX will discharge even while being charged with a non AC charger (including car chargers) when gaming/navigating is not uncommon.

Yes, it's reading A/C charging, but the charger is from alcatel with 400mAh output.

I've been charging it with Alcatel charger with 400mAh output. I'll try with Samsung charger with 5.0V output which says it's equal to 0.7A because I don't have the original (I think i have used it before, but i dont recall that it was any faster).
Could be kernel related issue, since there is an option to "Fast charge" via USB and it's enabled?

its not likely a kernel issue unless you are on some experimental one, but you would be able to easily find out by looking at the forum cause others would have the issue. And if you didn't know the Fast Charge option is to make your phone think its hooked up to a wall port if you are charging from your laptop or if your car charger is only being used a usb port thing.

It's franco kernel, nightly 251, pretty stable from what i've read in the thread. Also, I know what does Fast Charge option do, but I thought that somehow it messed something up. While I was googling for answers, I found some forum, where was mentioned the battery chip that is regulating the power it's using to charge the battery could somehow get messed up. Maybe I have bad batt.
mine battery too takes 3 hours to full charge using stock samsung wall charger. I'm using stock rom and kernel.
Mines takes 1 hr 30 minutes tops with fast charge

You are using a 400mA charger, the gnex comes with a 1A one. Go figure.

That is because the car charger most likely did not short both the data pins out, therefore you notice the discharging phenomenon because the phone will only take in 500mA without the data pins shorted or with kernel fast charge enabled. How is 500mA going to keep up with navigation, GPS and all other tasks?
Beamed from Maguro
Also realize that your previous phones battery probably had a lower capacity than the gnex therefore coming from 2 hours, 3 hours isn't that bad for charging a bigger battery

As has been stated get a GOOD quality charger. I might be weird but both my car charger and spare outlet charger came from Verizon. At least when i have had something not work they have been more than happy to open another and fully test in store for however long it takes. Sadly, my last car charger broke and I am too lazy to get another, my solution was to use a car inverter since I charge my other devices regularly on long trips. Plugging in a regular wall outlet from, oddly enough Motorola, does the job just fine. Alas, the majority of chargers my coworkers leave out are for lesser phones and will not even register on my beastly Nexus.
However i think i damaged my charger (original 1Ampere samsung wall charger) when i've been in Malta (i'm from Italy) last August. Before the holyday my nexus charged in 2 hours or less. During the holyday the charger heated a lot more than when using at home and now the charging process lasts about 3 hours. Also, when i connect the charger to the wall (even if the phone is unplugged) i hear a low almost-ultrasonic whistle.
I hope the damage isn't the battery.

Thank you very much. And the effective result is really a faster charging? Does it works good or not?
Hi, it's taking a really long time to charge my z1 compact using the usb port on my laptop (macbook air 2010).
It's been an hour and i'm at 27%.
Is this normal?
Also, is quickcharge 2.0 enabled on our phones? Would it make usb charging from a laptop faster? (I think mine is just 0.5 A, whatever Apple gives you).
Not sure on laptops but on my PC I could charge it for 3 hours to 100%.... While on dock I could charge it like 50minutes and it's full. Quickcharge 2.0 works only on chargers with quickcharge 2.0 support. Hence it won't work on laptops. And it's alot more slower since laptops has lower current output on USB ports than usual outlet chargers.

i charge using the dock an it fully charged my Z1c at least 3 hours. how can u fully charged yours at 50 minutes only?
I guess it depends on what you plug the dock into. I haven't timed it but I'm pretty sure mine charges from about 40% to 100% in under an hour. I plug the dock into a usb power adapter.
---------- Post added at 09:18 PM ---------- Previous post was at 08:51 PM ----------
Returning to the op's question, if I connect the phone to my macbook pro and then close the lid, the phone stops charging immediately. It charges just fine if I leave the lid open. I only tried it once overnight so I don't know how long it took to fully charge.

Model?
Charger suplied with my z1c is EP880.
About 2hrs20minutes from 5% to full battery.
And i think that is good, charging full battery in 50minutes isnt good for battery health.
Same as yours also... EP880. It says here output is 5.0VDC and 1500mAh. I'm pretty sure the battery is ok as it's holding a 2-3 day lifespan before I can drain it to lower 10%. Although I'm no power user. I mostly use the phone for texting and web surfing... The most battery hog usage I can do is reflashing ROMs in recovery which could deduct 1 to 4% of battery after reboot. Our electricity standards here are 220v of current.

Nice shot Riyal.
Same battery/charger/phone but 250% faster charging?
Thats a riddle for sure, laws of physics says that one of factors in equation must be different.
I suggest you to check yours battery in service centre.
2300mAh (healthy) battery can be charged with stronger charger in 50 minutes, ofcourse that isnt good for her longevity.
But with ours EP850 charger thats impossible, battery or electronics inside phone must be messed up.
Calculating with an output of 500mA from an USB 2.0 port, the charging time (0 -> 100%) will result in approximately 5hours. (Note that the battery is normally never at 0mAh)

Nah no need... I'm pretty sure battery is ok as whenever I charge it on my PC it's charging slow also like any other phones. So I think this is just really qualcomm's quickcharge 2.0 kicking in... Anyways I observed the phone. It's not heating up or whatever probably it's just because of the battery quality. It must be having good chemical reaction when charging hence less waste on energy.

Yours phone is .114 firmware also?
Well, something must be different, my phone and others are charging 2 or more hrs on EP880.
Found something interesting...
I have a energy monitor (http://www.elv.at/elv-energy-master-basic-energiekosten-messgeraet-1.html) between EP880 charger and the wall outlet.
If I use the usb cable EC801 (witch comes with Xperia Z1C) on my dk32 dock, the e-mon. shows about 7.5W energy consumption @~50% battery level !
If I use the usb cable EC450 (witch comes with my Xperia P) on my dk32 dock, the e-mon. shows about 5W energy consumtion @~50% battery level !
Conclusion: Phone charges much more faster with EC801 !
I like the older cable because its much more flexible then the new one - so that's the reason I used the old one and than I saw the differences on the measurement device....
FYI: Charging power is also depended on battery level -
Whats yours charging times (from 5-100%)?
Mine 2hrs-2hrs 20min.
I have EC-801 cable and DK31 dock with hims factory cable, same charging times on both.

Are you using the stock charger and cable? If not, what is the Amperage of the charger you're using? Are you charging from the wall or your computer?
I get a charge from 10% to 100% in around an hour in the UK.

Anywhere from 3-5 hours. Also if i'm using the device while charging it almost feels like its staying on the same level, something that I haven't experienced with other android devices.

I feel the same about using the phone and charging when playing games. No idea how long it takes to charge it tho, doing it while i sleep anyway.
I'm going to go wireless charging but sometimes I'll turn my phone off and give it quick charge since it charges faster. I know some people don't like to do that though.
the first thing I would check is that the usb cable is plugged all the way into the mains charger. When I first got mine it kept saying usb charging is slow, please plug into a mains charger, which I thought was weird as it was plugged into the mains, but on closer inspection the cable wasn't all the way into the plug, so it was thinking it was using a pc connection. plugged it all the way in and it was charging like a demon then.
Same freaking problem. It discharges 100-0 in 6 or 7 hours, with 1:30 screen on time, and recharges 0-75 in three hours. Have you managed to fix it?

I was having this problem when not using the included charger.
It seems that the phone actually requires to be quick charged (8V 2A) up to 65% or so and will then switch to the usual 5V 2A mode when it's reached this point.
As a result when I was using a regular charger (Nexus 7 charger, 5V 2A) the phone would "charge" but would actually slowly lose battery power during the night.
Gotta watch out for specific usb cables or charger adapters that don't provide enough power (as mentioned above).
I have 2 Nexus 7 FHD (2013) tablets and my Zenfone2 has exactly the same charger, 5.2V 1.35A
A standard cellphone charger is 5V and about 700-800mA.

I turned on Airplane mode and power saver while using a regular 5V Charger, and it was able to charge over night.....just not fully.
I thought I was the only one with this issue. Everything works fine with the included charger but when using my charger from my Nexus 4, it would charge a bit then at times start losing battery. I've used a friend's Nexus 5 charger and it has been hit and miss...sometimes it charges all the way sometimes it charges a bit and then starts losing battery.
Im also using ipad 2 charger..works well as a normal charger for zenfone 2. Especially if your gaming and charging same time..mine does not over heat..but dont recommend to do it always
In fact my question was more about who is charging all night their phones and also who is using his phone when the battery is lower than 15%.
Happy to see some others bugs on the ZenFone 2

Have you tried an new cable and charger, and check your charging port is clean.
Have you had any flickering on the screen, if so you might have a bad battery connection.

Had the same problem, replaced the battery without success as well. Had to replace the charging port and it's been working perfectly ever since.

This has just started happening to me. Sometimes it gets so bad that it dies on the charger.
I have had my T800 2 years tomorrow and the battery is fine, I use an magnetic microusb adapter so no port wear.
How long have you guy`s had your S1 before you started having problem with the battery? also do you game or use any apps that eat the battery or get the tablet hot as that is really bad for the battery.

I wonder if the battery went flat while you were not using it, was it turned off or just in sleep/standby mode.
John.
haha no its not the battery as i have already replaced it with a new battery and still the same. i think it was turned off.
so how long does it take you guys to fully charge your t800/t805 from 0 to 100% while the device is powered off?
From what i have read around 5 hours for the 10.5" for a full charge when in sleep mode, maybe a 4.5 hours when powered off.
But charging speed depends on an compatible charger and quality usb cable, full charge current is 1.75 amps according to my usb power meter on my T800

hmm, because mine takes 3 hours to charge 18%. eventhough am using a note 5 fast charger and also tried it with official tab s charger too no luck.????
the usb ribon arrived yesterday, so replaced it. still no difference.:crying:
Have you tried more than one usb cable, as it make a BIG difference, like 0.5amp vs 1.7amp you can have the best charger in the world but if your cable is faulty or poor quality.
Your battery could be bad (how long have you had your tablet?), or your battery power connector could be loose/faulty(mostly 8.4" S1), or you microusb port could have become faulty.
Also if you use a third-party charger it has to talk to your tablet in an language it understand or you tablet will charge slowly, there are a number of different charger languages Samsung has a different one to Apple, or HTC that is why an Apple charger might only charge your Samsung tablet slowly.
I recommend everybody gets an "usb power meter/monitor" they only cost around $10 and it allows you to see straight away how much power you tablet is taking from you usb charger and some brands can trick you tablet into charging at full speed on an Apple charger, I bought an Belkin 2.4amp charger and it was only charging my T800 at 900ma, I changed a setting on my usb power meter and now my T800 is charging at 1750ma

surprisingly i tried charging it with a cheap 3rd party cable and it has charged 48% in 2 hours whilst it was powered off, so it should take just around 4 hours to charge 100%.
when compared to the other 2 official Samsung chargers which charged more like 10% in 2 hours. quite strange results

Your tab will charge at full speed approx 1.75amp from 0% to 80% and then the charge rate will get lower and lower as it get`s closer to 100%
So the first 80% charges the fastest and then last 20% takes a lot longer.
EDIT: 80% of an 7900mah battery is 6320mah So it should take approx 4hrs to charge from 0% to 80% with an 10% charge efficiency
