I can't cite this but I remember reading that if you charge it from USB it can take about 4.5 hours, but if you use the AC charger it takes the normal 2 hours

I got mine with 35% and charging took forever. Going to let it charge overnight.

Mine has been on the charger for 2 hours now. Almost done. I didn't even power it on after I took out of the box. Started charging immediately

About 1.5 hours for me. I try to keep the nexus on this metal cooling pad, I think the cooler the battery, faster it charges...Somewhat. (And you would think it would be better for it.

Battery Stuck at 50%

Anyone else having a similar problem or know of a way to fix it?
It takes a *while* to charge. Mine just hit 60%.
We shall see, been charging all day... anytime i take it off charging drops to 40ish%
Im using battstatt and it drops by 10 percent.....90.80.70 im gonna let thr battery die completely before charging and see if it changes

OK, I just saw this in another thread too... mine has maxed at 60%. Gonna le it rest, shut it off over night and put it on another charger. See what everyone says tomorrow!
Seriously guys, charge it from an outlet. It charges *really slowly* through USB.
anyone else go through the initial charge, recharge and have it at 10% 9 hrs later?

10 hours total on 4G? That's not terrible.
Charge via USB that is connected to your PC takes forever...but it does charge.
But if you unplug it and charge via the power adapter, it is much faster.
i charged mine via usb and the wall socket, wouldn't go past 50%.
I went to bed and plugged it in to teh wall charger (charge for ~7 hours), checked when i woke up, 50%
went to the verizon store and they gave me a new battery (started at 50%). plugged the phone in 2/3 hours ago, im still at 50%
my dad mentioned it could be a bad fuel gauge chip (he works at TI)
So for whatever reason, you have to use the charger that came in the box. I've had the same problem, but it was because I was using chargers from older Moto phones and HTC phones. Now that I'm using the actual Bionic charger, it's charging fast like it should.
Silly, but it apparently is the case.
I bought a wall charger that you take the battery out of the phone and charge.takes 2 hours with xtra battery 15 bucks mobiletech

From what I've read about newer handsets, the phone needs some time to figure out know how to convert raw readings into percentage of capacity. I believe, the phone figures out how much charge a battery has based on the voltage. And, I don't think the relationship is linear.
My battery seemed to be horrible the first day. Today, I've gone through 30% after 5 hours, with the screen being on for 35 minutes and wifi connected for just under two hours. I don't know if the battery is "breaking in" or the phone is reading the level differently, but things are looking better.

Charging time and use

Hi,
How long does it usually take u guys to recharge ur note from dead or almost?
It took mine. Over 8 hours to charge from 12%.
Also if keep my note on charge but im usimg it for browsing or whatever, my note still dischares.
Is this normal for the note as my htc Desire didnt diacharge while using it while connected to the charger.
Thanks
Neil

Hmmm I've never really timed it but its gotta be around 4hrs for a full charge.
I have been playing Stardom even when charging and it gains battery.
That doesn't sound normal at all.
If u r charging from USB port den its possible. Charging from ac will be a different story
Sent from my GT-N7000 using XDA
Charging by USB is at around 12% per hour, so it does take 8 hours.
Charging by a/c is upwards of 35%/hr.
Some of the apps usage would demand battery usage at 20-25% per hour, so if your battery usage is more than your charging rate then you would be losing battery which is what might have happened when you are using USB charging etc.
If your stats are for a/c charging, then I suspect the charger.
Yeah i charged for 8 hours with ac and also got discharge while using the note and charging.

Are you using the stock charger? What is the battery time you are getting?

Depends on what you are using for, but it still doesn't sound right.
Mine charges from 5% to full in about 3 hours when it's just sitting
on the table and I'm just using it for a phone call every now and then.
charging shouldn't take more than 4 hours when done from an AC outlet. just check if you have original batteries and charger. if not, take it to the shop and get it replaced immediately. 8 hours is just too much.

Im using the stock charger.
Rocket rom / Abyss 4.2 kernel
And battery life was around 20% after around 14 hours then i put it on charge and used it for about an hour but it discharged to 12%.
I am using the device heavily at the moment as ive had it only a few day.

When you are using it heavily while charging it might be normal,
try leaving it alone while charging for one cycle, that'll give you
an indication.
If it's still substantially higher than 3 to 4 hours under these circumstances
you've got a problem, either battery or charger have an issue, or there's an
app sucking battery like hell.
as said, 3-4 hours is normal. Do you have a battery drain issue when in normal use? if yes, then u can use betterbatterystats to check which process is using the juice.
Also, its advisable (in the first cycle after flashing a rom) to charge the phone with switched off. After full charge, take out the battery, wait for 1 min , reinsert & restart. This will help to reset the battery & start afresh.
From 8% to 100% with the charger it took me less than 3 hours.
I only charge by USB on my PC and its never taken close to 8 hrs for a full charge..
The only time charging has taken a very long time for me is when I ran a ICS ROM.
So i did a charge with my usb cable and it tool half the time. Maybw theres a problemwith my ac charger.

use a different charger, i put it down to a **** charger from samsung as mine did the same, woudl discharge even tho was supposedly plugged in and charged

How's your battery life?

My battery life is decent, but the charging time is the slowest I've ever seen on any device I've ever owned. I'm not even kidding. Surely it's just a defect on mine right?
Negative. My charge time was ridiculously slow. To the point that while I was charging in my car, if I was doing things along side it, my battery would actually go down. Plugged into wall, it is slow but charges though. Maybe its just US or a small number?
Waiting to get mine still. Did anyone else notice that on Sprint's website it said the One has a 19 hour battery life?

It seemed a little better this afternoon, but I've basically had the device plugged in since this morning(10am)(got it at 55%, and albeit the majority of the time, it was plugged into the vehicle[which hasn't been very good anyways[[my GS3 also loses battery while on charge if doing anything concerning navigation or streaming]]]) and it literally hit 100% about 20 minutes ago. granted I've been using it like a pack mule. and I'm sure you have too.

i heard they packed a li-polymer battery which makes the battery hold its charge longer for the life of the battery when compared to a li-ion battery.. and i dont think htc enabled fast charge like most devices...maybe someone will mod that for us...we need fast charge!!!!!!! still waiting on my ONE

Actually I haven't used it at all. Got it at 2 PM, was at 60%. Dropped my mom off at the airport immediately after, came home and it was 50% at 3:20 PM (which is okay because LTE was on by default and it's super patchy here so I turned it off). Plugged it in and showered, 15 minute shower and I come out and it's 50% still (plugged directly into the wall). Went to work at 5, 55% when I got there. Plugged it in to the computer we have at the front desk and over the course of my 5 hour shift it eventually hit 95% before I had to leave at 10 PM. Un-****ing-acceptable.
yeah, I'd say mine is a little better than that. I left the screen off and didn't use it for like 2 hours and it went from 73% to 91.
I bought a 2.1 amp charger and it hoes from 0 to 100 in 4 hours

I don't have my One yet so I can't confirm this personally, but I've read in a few different places that the charging rate is a little slow compared to other phones. My guess is that HTC is trying to maximize the lifespan of the battery since it's non-removable. Quicker charging would generate more heat and might cause it to wear it out faster.
Yes this is the case. Check anandtechs review.
Brian speculates just as you do that it is for longevity.

So how is the battery life for everyone? Hopefully it's good since it takes time to charge

First day I got 15 hours. That was the usual installing apps and watching YouTube videos and showing my phone off to everyone at work. Will probably be awesome once I don't have such heavy usage.

If I'm not mistaken, the phone has a smart battery or a circuit inside the battery that prevents it from drawing too much current. It is pretty much a standard among smartphones these days. Therefore, even though you use the 2 amp charger, you may not charge faster at all.

Horribly slow charge times on mine as well. I think the GS3s super fast charge ability spoiled me.

My Galaxy S3 definitely charges faster with a 2AMP charger than 500 mA charger.
Do not charge from a computers USB port, they are going to be slow as **** without fast charge.
Just use a 1+ amp charger. Pretty simple people.
Don't put excessive work load on the device while charging in the car either

The way people are talking, it seems that simply having GPS and navi going are too much.

I've found thats too much for most phones. It all depends on the charger(most car adapters are crappy), I'd assume. I've had the same with Evo, Optimus, GS2, and GS3. If anything is running alongside gps/navi, it destroys the battery

I let my battery run dry and now phone won't charge.

So my phone turned off from being out of battery and now it won't charge. I was able to power it up again for a few minutes and it was not charging and there was some error that said something like "Phone won't charge, please use stock charger". What do?
Update: I charged it overnight while off and it was able to charge back to 100%. However, it is still unable to charge while it is on or off (for a short amount of time plugged in at least). Not sure if letting it sit for hours like when I charged it overnight would work.

Just keep it plugged to the charger. Some time when the battery is really dead, it takes a while for it to get charge and turn on the device. Try it. If it still doesn't work, send it in.

Plug it in using the charger and cord that came with it. Leave it plugged in for a hour. Orange LED will come on eventually well hopefully.
Don't calibrate the battery again.

[Q] Moto G Charging Time

Hey guys, How much time does it take u to charge your 2nd gen moto G from 0 to 100 running stock and locked botloader. I'm having an issue with my device, it takes 3 hours to charge with wifi and mobile data off. Is it the same with everyone ?

Change your charger
Actually its not the Phone's issue but the Chargers'
I am using my Lumia's charger and phone gets charged in a hour from 0-100%
I will have an answer for this in a few days.
Theoritically it should take 225mins to charger from 0-100% with stock charger..
Anyone knows maximum charging rate?
Just did a full charge (0-100%) without the OS running. Took 2 hours. I'm using Anker Power IQ 40W 5-port desktop charger and Moto's USB cable.
Remember, quality of the cable (as well as the charger) directly affects charge time. So try to use official or high quality cable and charger
Search Google for "Cables Can Significantly Impact the Charging Speed of Your USB Devices" and click on the LifeHacker article

Mine also takes almost 3 hours. That is because they have given a 500mAmp charger . I am using my iPad charger block rated at 2.1A and it charged from 25% to 100% in 70 minutes
Yep,
Use a 2 Amp charger and you will get full charge in 1.5 hours.
