How to do you charge your One X?

Just wondered how most people are charging there One X? Personally I always turn it off and allow it to charge until the light goes green. I've never charged it when it's still been turned on.

I've never switched off any of my android phone's whilst charging. What happens if you get a call? I also try to alternate between charging on my pc and the wall charger.

Yeah fair statement, I had thought about that. I wasn't sure if it was bad to say plug the phone in at 11pm until 7am (8 hours) charging whilst it being turned on? I assumed if it was going to be plugged in say for that long that you should turn it off.

I just plug it in - went to bed on 80% last night but fair enough I'd hardly used the phone all day (standby battery life is incredible)

So you stuck it on charge just to boost that extra 20% yeah? How come you didn't just leave it until it was low?
Should of asked if people would partially charge it or if they always ensure its fully charged.. Can't amend the poll now though.

I was thinking about trying that - might do that tonight and see how it lasts...

I plug it in to a usb cable

i charge my hox every night on the wall charger while turned on. even if it has 80% left. i am to afraid that my battery level goes under 20% (i heard that falling under that level can damage batteries).

Where did you hear that? Mines dropped to 14% before and I then turned it off and charged it and the battery still seems fine. Wasn't aware you could damage the battery if it got too low...

I killed my battery first 2 charges - never have in the past but thought I would this time

I have always charged with the phone on, all my phones since way back having an analogue Nokia mobile and never had any battery issues. Only time I have ever switched my phones off is if I was getting on a plane or the battery got really low and didn't want it to go completely flat.

Just plug it in whenever. Modern li-poly batteries doesn't have memory and charge cycle life is based on full charges.
Part charges actually increase life due to low % cycling

Agreed.
One thing to note is that you should never let it completely drain the battery, the phone will switch itself off once the battery reaches critical level then it needs a charge. I'd recommend charging it when it reaches 5-15%.
Also I'd never leave it charging over night it interrupts the cycle, if I have to charge it over night I set an alarm to go of after a few hours and unplug it.

i have 3 or 4 charges from different makes-and only htc charges the quickest. the worst is usb cable and car charger. but due to usage i need to charge twice a day

Dude...
I always charge overnight - purely for convenience really.
Can you explain the above to me? I'm not sure what you mean by it interupts the cycle?
How does it effect the battery ?
Thanks alot

You are 100% right most modern phone battery’s don’t have memory any more so no need to worry about it, and no need to do full discharge and recharge cycles to maintain battery health, and if they do they normally tell you in warning labels or in instruction manuals, for example I recently bought a new shaver and it tells you to do a full discharge and then leave it on charge for at least 12 hours every 3 months to maintain battery life.

batteries have safety features built in so don't worry. What for you looks like 0-1% left - what android is showing you, might be actually 10-20% as seen internally by the battery.
Also, I have completely discharged my phone once, I simply left it at 1% and waited until it shut off. Then I charged to 100%. From then on, I charge whenever I want, phone is always ON.

Ebay 2m cable (the HTC one's length is a joke).

I use a charging cable.
My friend sticks it next to his head and uses his brainwaves to charge it.
Both seem to work fine.
Im really sorry for this post. I could not resist.

You guys are ridiculous. Just plug the phone in and it charges.

HTC one x time for full battery charge

Hi
Please post the time it takes for you to charge the phone from 0 to 100 when it is not being used and is on standby also the mention the update you have
my phone takes 2 hours with 1.28 update

That is a good time. With my New one i need also 2h. With the old one x i needed more than 6h

3h

The first charge was about 6h!! (Wallcharger , not USB)
I don't know how it is now. I plug the phone to the wallcharger in the evening and unplug it at the next morning

That's what I do as well but I don't think its the best way to charge the phone as sometimes I wake up in the middle if the night and the phone is close to exploding from the heat it generates while charging.
But as how fast it charges, I think around 2 hours for me too. USB takes a little longer, I'd say about 5-6 hours.

Your phone is overheating from charging? Something wrong. Mines very cool, basically like its turned off or idle.
Takes a while to charge fully though

Actually i think it's ok if it gets a bit warm when charging BUT it should cool all the way down when getting to fully charged.

I always plug mine in overnight... I wish I could specify a slow charge to prolong battery life. No idea how long it takes to charge.

There's no need for it. The charger stops at 100% and goes into battery mode until 95%, then starts charging again. It never approaches overcharging at any point. This is also why sometimes when you unplug your phone, it drops a few percent almost immediately, cos 100% battery was already achieved some time ago, and has been on battery the last few %

Mine takes more than 4hours .

I think you are right. It does happen to me sometimes when the battery is showing 100% and once unplugged and used for a few minutes it drops pretty quickly.

hehe i know i orginally said that i was getting 2 hours(this was the first charge cycle of the phone )
but now it takes me 3 hours for a full charge this is after the 1.28 update

going to add here, go to settings and power and check the status if it says (charging - USB) then it will charge slow for me it's 20% an hour from a USB. I also have a charger cable (has plugs for iStuff, micro USB/ mini USB and that tiny one for Nokia) and when that it plugged in it says (charging - AC) and its a lot faster.

2.5-3 hours max
charger = 5v 1a

2.5 hours here

Thanks for the thread. It also takes mine just under 3 hours from completely dead and I was thinking that was on the long side. (My Atrix 4G used to take 2 hours.)
HTC One X/AT&T

Charge time from 5% is about 3h

Hello,
i own an htc one x and the charge time are usually around 3-4.5 hours. now granted many say their average charge time for this phone is about the same. but what bugs me is that i charge my phone with a 5v+/- 1 amp charger in a 110v 50hz socket.
i have an app that measures battery usage, charge times and the amount of mAh being used or stored @ a given time interval. now when i charge the phone through the 110v socket i get 386 mAh the max from the socket. where as at my school we use 220v sockets (i have both connectors for my phone) and i get easily 895 mAh reducing charge time to just over 2 hours. so my question is.
the specification on both chargers is:
+/- 5v 1amp
so even if there is a difference in sockets both still list 1amp. so why do i only get under 400(386)mAh at home and just under 900(895)mAh at school?
btw. noob. if im in the wrong section plz redirect me. only board that looks close to what i need

do you think it can be faster?

i would say mine charges full in an hour

charge current is programmed in phone's firmware below 1A for AC chargers and below 500mA for USB (don't remember actual values), so even if a 2A charger is used, charge time will not vary.

Mine goes about 1% a minute, I find it good enough for me.

Full charge takes about 1,5h so for me it's not long. But comparing to Xperia S and 0,5h Arc S charge takes ages

When it gets to 90% or maybe even 85%, it slows down its charging, and displays the LED as green, it then continues to charge, this is the economic techniques of the charger, at least that's what I remember from the manual. So it saves energy as most people charge their phone at night, as it gets plugged in for longer periods of time.
This was the first device that introduced me to that concept, the iPhone 3G I had before focused on faster charging. I am unaware of any other products that use green charging methods, however I'm certain other devices will do.

charging a lithium based cell requires a first step using a constant current supply, until voltage reaches 4.2 volt; beyond that point, charging switches to constant voltage, providing the last 10% or so of charge to the cell.
every li-ion charger does so, but someone signals "cell charged" (i.e. green led) when charger actually stops supplying current, others when transitioning from constant-current to constant-voltage mode.
and if that last 10% of charge is not so vital for you, i suggest to disconnect charger as soon as led turns green, because at that high voltage, corrosion of battery's anode is faster and so life of cell and it's capacity is reduced on the long run.

MYTH NO. 2: Overcharging your lithium ion battery will reduce its battery life
One of the most common myths that we have heard about lithium ion batteries would be the need to plug it from its charger after being fully charged, since overcharging the battery/device will reduce its battery life. The truth is, lithium ion batteries cannot be overcharged or can be reduced of its battery life through overcharging. What’s good about these batteries is that that already have built-in circuits that will cut off the power once it has been fully charged.
However, it is a good idea to unplug or remove the battery once it has done charging because the heat from poor ventilation or from charging will cause it to blow up. Another reason why this is an important note worth remembering is that batteries discharge faster when heated thus, reducing its lifespan.

that it's true, and is a residual myth from the age of stupid charger that went on charging forever after 100%.
perhaps I was not talking about overcharging, but to terminate charge before the constant-voltage part (at about 90%) if you want to slow down capacity reduction and so prolong battery life.
life of li-ion cell is optimal at 40% charge, but obviously a cell kept at 40% is useless :laugh:, so only thing I can suggest is to avoid reaching full charge if you can.
it's a form of perfectionism, let's call it so

I undervolted my phone, turned off WiFi, sync, brightness and put it on powersaver, charged at 1% a minute which is much faster than its normal charge. Good for me to know, obviously turning the phone off is basically the same

[Q] Painfully Slow Charging

Hi
I've got a brand new htc M8 and enjoying it immensely, but there's one thing that's worrying me. My first three or four charges were very quick--an hour or so from 60-65% but over the last few days charging has become an ordeal. I've read numerous forums and tried a number of techniques, most recently discharging to 10% then recharging (which took nearly 9 hours). I went out this morning and returned with 85% remaining. Plugged it in and Dashclock forecast three hours and twenty minutes to regain that 15%.
I'm using the charger provided, but have tried a number of others as well.Any other ideas out there?

if u have samsung lg or any original charger in ur house test it i normally have 1:50 or 2hr for fully charged
change ur USB CABLE
FIRST THING TO DO IS
CHANGE UR USB CABLE IF IT DINT FIX
SECOND THING IS CHANGE THE CHARGER AND USE ORIGINAL CHARGER FROM ANY MANUFACTURER
IF AFTER THAT UR GETTING SAME TIME CHARGING ITS UR PHONE MATER NOT CHARGER

Do you have fast boot enabled?
If so disable that, then power off the phone for a few minutes then power it back on and try to charge.
My neighbor had fastboot enabled on his and performance and battery life always sucked.. after disabling that he saw a lot better results.
Is your phone being used while charging? Is it getting hot while charging?

But be careful when comparing charge rates, as the current drawn reduces as the battery becomes more charged.

Very slow charging

Anyone else notice that with the supplied charger charging ins't what it should be. My iPhone 5 charged almost twice as fast as this phone. I find it kind of annoying. I did order one of these chargers hoping that solves the issue.

No its not. Especially when your using the phone and its on 5% plugged in. Takes forever to reach 6%.

I'm having literally no issues with charging from dead to 25% in about 15 minutes. 2 hours to 100% im very happy with the speed of charging and this is using my m8 charger as the m9 one is still sealed in box.

I've been using the GS4 charger, with a high output cable. The Samsung charger is 1.5A where the HTC m8/m9 charger is 1.0A

the supplied charger is definitely giving 1.5 amps to mine. charges up pretty quick. with a quickcharge 2.0 charger it's crazy fast to charge.
One thing to note is it will take a faster charge the lower the battery level is, which means more heat. if you're also gaming with it, you could be bumping against the battery charging cutoff temperature. I only ever saw this happen on my Tegra HOX+. IIRC HTC has the notification LED blink in alternating green and orange/red when this happens. I'm guessing you would have mentioned temperature in the OP if this was the case, but I figured I'd bring it up.

Sorry, meant it was 1.5a for HTC and 2.0a for the Samsung one. Didn't have them on hand to check.

iPhone 5 battery is 1,440 mAh... M9 battery is 2,840 mAh. 50% charge of Iphone battery doesn't equal 50% charge of M9 battery, in terms of charge time.
I believe the rate of charging to decrease while you use it to prevent the phone from overheating. (My M8 does this as well)
My stock charger is fast, and my quick charge 2.0 is crazy fast.

Yup i got the same issue gonna take me 6-11hrs to charge and its very slow charging

I had a similar problem to OP. The second night I had my phone I plugged it in at 11 pm with about 5% battery left and went to bed. At 5:15 the next morning (6 hours later) it was only at 85%. I can't tell if there's still a problem or I just think there is because I'm paranoid about it now. I haven't run my battery down that low since, and looking at the charge current with Ampere seems somewhat inconclusive. I may have to run it down and then keep an eye on it while charging to see what's going on.

Something IS wrong with SOME M9 phones (I think)
I have one of the "bad" ones. Mine takes hours and hours to charge, whether on the cable and plug that came in the box, or on any others that I have around - some I know are 2 Amps. I think there is something seriously wrong with some of these phones, based on what I am reading in this thread, and on my own example. I have had my M9 for just a few days.

I'd like to post a follow up to this thread after having the phone for a couple of weeks now.
I've had several occurrences where my phone didn't fully charge overnight. The worst was a few days ago, I plugged it in at 5% and the next morning (6-8 hours) it was at 1%, it actually lost charge. I noticed before unplugging it so I looked at the history in Battery Widget Reborn and it showed the battery level just slowly dropped from 5% to 1% without any jumps or dips. The battery icon at the top of the screen showed it was charging but it died at that point so I didn't get a chance to open Ampere.
I think it's the charger (and/or the cable) that came with the phone. I've tried several other chargers that have all worked reliably:
- The QuickCharge 2.0 charger that came with my wife's S6 charges my phone really fast.
- I have a Kmashi external battery that also seems to charge it relatively quickly.
- Two older chargers that are several years old (both rated 5 volts at 0.7 amps) charge it from around 30% to full in 3-5 hours.
At first I thought it might have been a wakelock problem, but the battery has been dropping so slowly when the phone is just sitting in my pocket that I'm confident now that it's not wakelocks. I don't know if HTC is likely to send a replacement, but I'm going to stop into the Verizon store that I got the phone from to see if they'll replace it.
Gilligan

My phone is also odd when charging.
Half of the time it takes 6 hours or more to charge. If I look at GSAM battery monitor it shows a charge current of around 350mA. If I then unplug the charger and reconnect after 15 seconds I get over 1300mA charging current, most of the time. (It takes GSAM a while to show an accurate reading). Occasionally it will take a few tries to get it right. Once I get a good reading over 1300mA the phone will charge in 1.5 hours like it should.
Something very buggy about this phone's charging circuit. I get the same behaviour with all chargers and cables, even my battery bank.
