Hi All, I have question. Which one better to charge
1. Wait until Battery level reach 15% or less
2. Charge it every we want it, example battery status in 40% because we want to travelling, we charge it until 100%
3. Charge it every morning
4. Other Tips?
Best Regards

Hello
You should just plug it in when ever you have the chance m8.
Li-ion and lipo batteries does not suffer from the memory effect as nicd and nimh batteries did.
The li-ion and lipo batteries will most likely die if you do a full discharge, but no worries, when your phone tells you that it's out of power, it's not fully discharged.
Your phone has at built in protection, that shuts down the phone before it uses all the power on the battery.
(Have been working with batterie for many years, as I have been flying eletric model airplanes, with all types of batteries)
There are a huge number of threads on this!

Thanks you for this tips... now I have more knowledge about battery.
A little bit question again.
What should I do, when I charge my HTC Desire? Keep this gadget turn on or turn off this gadget and turn on again when the charging has completed?

Just keep it turned on m8.
leaving it on has a disadvantage
as soon as battery is full, it discharges. at a certain point it would charge again.
you lose unneccessary charging cycles for your battery. so charge over night with turned off handset.
Not true really. The life of Li-ion batteries is mainly rated in full charge/discharge cycles between what the manufacturer recommends as the limits. Fox max life this is often a maximum of 80%SOC and min of 20%. They ship them about 40% SOC as this is where they have longest shelf life. The phone manages these limits for you so you don't need to worry. The best thing to do is to keep it topped up but let it run down enough during the day, or it reduces battery life (think laptop that gets left plugged in Vs one that gets discharged a bit per day - leaving it plugged in kills the battery).
IMHO - Use it until your next at a charger be that at 70% or 7%.
JAmes.
This thread here might be a good reference for this topic.

1. I always try to charge it 10-15%
2. Sometimes i do charge it if the battery is 40% and im worried it might not last because i go somwhere, so charge it till full and unplug
3. Most of the time i charge it over night having the phone on.
Right now, end of day 2 and battery level is at 29%, probably due to 3g turned off as got connection failed error for couple days and cant connect :<
Put my new second battery to charge last night around 9pm - turned Desire off. The green light came after midnight, but I let the charger stay on. I disconnected the cable around 9am this morning - and the phone was on!!
It looks the phone turns on automatically when its fully charged(???!!!)
The charge was 94% with the green light on. Makes me doubt if the suggested (see other threads) initial charge needs to be 12hours. :/
I am getting the phone for christmas and was just wondering if I have my parents charge it the night before, will it last me all day? What is battery life like on the first charge?
You'll likely burn through it pretty fast on a first charge. Best I know, it's not optimal until about 3-4 cycles.
Mine was pretty horrendous at first and then again for the following couple of cycles after that. Now on 4.0.2 and a number of cycles in and I think the battery life is stellar when you consider the screen size. Pretty similar to my GSII so cannot complain.
My advice. .. take the charger.
Regards.
I got about an hour of continuous tinkering after a 10 minute charge. Had to plug it in after that.
The first charge will be the longest lasting charge you will ever have on this battery - depending on your usage.
LiIons degrade a wee tiny little bit with every subsequent charge.
Thanks, I can't wait to get it.

While this is true, I dont think its calibrated the first time.
I got my nexus yesterday and charged it up from 50 to full and it was literally at 0% 10 hours later, today is a different story, I've been able to get about 12 hours of use out of it and have about 35% battery left

Calibration only affects the battery icon, if they use poor logic to calculate the charge. The system can read battery voltage precise to 0.001 volts and it's actually quite easy to gauge a LiIon cell: 4.200 V = full, 3.600 V = empty (without load on the battery)
My first charge only lasted about 5 hours, and that was because I was playing with the thing the whole damn time. ;-)
My first charge
This is what I got on my first full charge. Was on Wifi for most of the time. Bluetooth was on often in the beginning to transfer files.
Used GPS for like. Facebook sync was off. Gmail, Google+ on. No Reader, Google Photos, Docs sync.
I bought the extended battery and it both were about 40% charged. You'll want to burn it down completely till it powers off, then give it a full cycle.
You'll kill it just by setting it up, playing some games, playing with the OS, reading XDA Rooting guides, taking pictures etc.
Just kill it, then put it on the charger while you get a shower and dressed.
...then you'll probably kill it again by the end of the day cause you can't stop plating with it.

How long does it take to fully charge your One-X?
Mine is already charging 3.5h to get from 40%to 80%....
Using the default charger, and not using the device.
Isn't that a bit to long?? My HD2 was completely charged in 2h..

I am no expert, so don't hold me on this one, but I believe your device charge should speed up due to firmware updates and also once the battery has been 'worn' in - just stuff I have seen about.
Can anyone else provide me their charge times? How long it takes to charge from A to B?
Pls mention with wall outlet or USB.
I've noticed this as well. My Arc charges in like 2-3h to full. the One X takes about 2 hours to get to about 60% from 30% (using USB).
edit: wall charging takes just as long.

Can't be normal, right? 2h from 30% to 60%...

Interesting reading about lithium based batteries
this is a quote from batteryuniversity dot com
Simple Guidelines for Charging Lithium-based Batteries
• A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
• Charge at a moderate temperature. Do not charge below freezing.
• Lithium-ion does not need to be fully charged; a partial charge is better.
• Chargers use different methods for “ready” indication. The light signal may not always indicate a full charge.
• Discontinue using charger and/or battery if the battery gets excessively warm.
• Before prolonged storage, apply some charge to bring the pack to about half charge.
• Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.

And I also read that charge time should be almost 3h for a full charge(i suppose this is when device turned off). You could get about 70% charge in about an hour if I remember correctly.
Hmm not gonna turn off the phone for every charge tbh...
Sent from my HTC One X using xda premium
While charging and using the phone it takes around 5 hours to get from 5% to 14% when not using but charging takes around 3-5 hours to charge from 25% to 100%
My second charge, from 0% to 100%, with device shut down took 3.5 hours to show the green led... quite a long time since I was using the wall-charger... I hope it will improve with the fw update and after the battery has been "initialized"
Today I began charging my HOX at 1:44 (1%) and it finally reached 100% at 4:59.
I was using HTC's charger.

same here, about 3h from shutdown with 0% to seeing green LED
using wall charger
Took me three hours with original HTC wall charger and original HTC cable (no extension) to charge from 4% to 100%. Terribly slow!
EDIT 1 : Apparently BWM doesn't show accurate power draw while idle on the One X for now, so my post has become totally irrelevant
I always install Battery Monitor Widget on all my Android devices and monitor charge and discharge constantly.
On my Desire Z, if it's below 70%+ I get a charge rate of about 750mAh from wall socket.
But on my One X, with the same charger (both are rated for 1amp, and both HTC), my charge rate drops to 450+ at 60% battery life.
It's probably a software issue, but charging the One X does take noticeably longer.
I don't think it is a software issue, as the battery pack is larger than before. Also when you are active the phone itself draws large amount of current and it definitely slow down your charge rate.

When your phone is idle with screen of, it shouldn't drain large amounts of power while charging. Can't imagine that has a huge influence on charge times tbh.
And for capacity, my HD2 was charged in about 2H for a 1200Ah battery, this 1800Ah One-X batt should be full in like 3h... not 5 or 6h...
The official wall charger took 2.5 hours to fully recharge the One X
Ok after an amount of charges, it now takes only 2.5h - 3h anymore for a complete recharge.
Official wall charger.
Did a charge on mine this morning from dead, took 2.5 hours to get to about 90%, left it for another hour but it didn't go up the last 10% stayed on 90 even after the extra hour. Off the wall

I'm thinking the same... I don't mind turning it off on a night for the first 2/3 charges but personally this is my only phone (don't have a house phone) so will be keeping it on through the night in case someone needs me in an emergency etc...
Was interesting to read that batteries prefer a partial charge and do not need to be fully charged; which is good actually as mines got around 18% left and I'm about to stick it on charge for the next 8 hours.
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

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 ?

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.

I've had my S3 for a few months now and I've noticed that I get different battery life depending on my charging habits with nearly identical use.
If I charge it overnight (thus, it remains on charge fully charged for a few hours) I get about 8 hours of general use.
If I charge it during the day and monitor it and take if off charge soon after it is fully charged (thus, it does not remain on charge fully charged) I can get about 1 to 2 days of general use.
That's a HUGE difference just from charging habits. Anyone else observe the same thing?

It seems to be the exact same with me. I always charge my phone over night and it will drop must faster than if I partially charge it or take it off when its done. I would like to know if anyone has a way to fix this.
Same here. It really annoys me, because I don't really want to wake up in the middle of the night to unplug my phone.

I think that's a lithium ion battery thing in general, and not just an S3 thing. I don't know the exact guidelines for charging a lithium ion battery because there is a lot of conflicting information passed on through word of mouth, but I think - as I prepare to pass on my own word off mouth theory- I think you're supposed to charge your battery before it gets less than like 10 percent discharged, and you're not supposed to let it overcharge. There's something about how lithium ion batteries have a memory to them and if you charge them improperly, you risk slowly killing your battery over time.
I realize now that you may already know all that but are just asking why overcharging your battery specifically leads to less battery life that day, but I don't know that and I already typed all that carp out, so it's staying

Phone charges to 100% then doesn't charge. Even if it says 100 while plugged in it could be down to 90. I have no idea why this is cutting a day off your usage time, but that is why it is shorter than if you unplug it. Could be that you use it more during the day and you are getting longer usage times since it is charging while using and unplugged at night while it is barely using 1 or 2 percent of the battery for 8 hours.
I put mine on charge at night before I go to bed, and then disconnect when I wake up the next day. It comes the whole day until same time in the night to put to charge. I normally get like 3+ hours display (on auto brightness, and full sync) with about 30% battery left.
Once battery is charged to 100, even if its connected to charger, there would be only trickle charge, and not regular charge to the battery. But it shouldn't make a significant amount of difference between taking off immediately or later in the morning.
I just leave it on charge overnight. There are sensors in it to prevent overcharge. What hurts lithium batteries is letting the battery drain to 0%.
