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

Why can't I get a 100% charge?

When I charge my phone it reaches 99% and it remains there it never reaches a 100% charge.
And my led notification is always red never goes green.
Did anybody else notice this?
Sent from my HTC One using xda app-developers app

Maybe you are using 3rd party application like Battery Motifier in which the settings of battery full is only set to 99%. I am using this application for charging my phone then this app notifies me once it was fully charge using a sound notification. Try to check your applications installed to your phone maube you have same kind of application or the likes... hopefully it helps

Haven't installed anything out of the ordinary that would cause this.

I know for some Samsung devices they don't charge all they way. It is a measure used to save the battery
Sent from my Galaxy Nexus using xda app-developers app

My one did this but it was because I was using a Samsung charger (don't want to open charger or headphones in case of resale) so I tried my HTC one X charger and it went back to100%.

I am using supplied charger, didn't see 100% yet.. But will see later on..

I had to get an exchange for my first handset. It had major gaps, and battery never fully charged.
It seems it was due to a dodgy battery. Even if the phone was left on charge for 10 hours it still wouldn't fully charge, turned on or off.
If it gets really hot while trying to charge after 98% it may be the same thing, and you should possibly ask for an exchange, or get it checked out.

How do you know the battery is at fault?
Sent from a pizza..

Why not let the phone discharge until it shuts off, then try to completely charge it from empty. I had an atrix once that would only charge to 99 after most Rom installs until I did this. Always figured it was a battery calibration thing.

Interesting fact, Lithium-ion polymer batteries do not charge to 100% capacity by design. They are actually quite difficult to charge correctly (in the electrical engineering sense, it's still plug and charge for the end user) and it is not worth the additional hassle to get to a "true" full charge. What the phone reports as 100% is only 2-3% off of the theoretical max capacity so in practice the difference is not noticeable.
It's hard to say if this effect is whats responsible for what you're seeing, but it could be related. Another possibility is that you simply haven't let it trickle charge long enough to report 100%. The last few % charge of any phone battery is going to go at a much slower rate compared to 20-90% for example. Really the only thing you can do is the somewhat standard advice to get a full discharge/charge cycle in to let android re-calibrate itself.

this is normal, it eventually does it,m dont worry about it
sometimes if i use the phone whilst its on charge it turns green
im not bothered, 99% is good enough for me it trickles down at the end really slowly
even 95% is good enough i usually unplug it at 95

I had the same thing when I got my phone, I was using a cheapo micro usb charger that did not have the beans to charge the one.. it got to 99% always.
Switched to proper one with phone and voila green light & 100%
For the record an iPad 3 (aka "new" iPad) charger works if you swap the USB cable also.

I am using the charger that came with the phone, and it has been an hour on 99%, any advice? To the ones who reached the 100% mark, how long did you leave it at 99%?

Happened to me too, with stock charger.
Finally got it to completely charge. I let it discharge to 2 percent than charged it with the touchpad charger. Most probably the first step isn't required. The charger outputs 2A. Will try other chargers including pc usb..

Let me know how it works ok... Seems like maybe its a stock charger issue...or maybe i just need to let it discharge to less than 2% most i ever let it down to was 9%...keep me updated please...

i had that problem on my s2 with some custom roms. it would charge to 100% if i unplugged it rebooted and plugged it back in. also it went away after 1 or 2 battery cycles

Reboot device when at 98/99%, then it will show 100% for some reason.

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.

It wasn't my intention. I was just playing a game and decided to play till the battery run dry.

How's my charging routine?

Is my charging routine bad? Here is my daily recharging
I let it charge over night. By the time I get home its normally in the 60% or so. So its left on all night until about 7am.
Then about half way through my day I charge it again while I'm at on my office. By then the phone is around 70%. So I let it charge to 100% then move on with my day.
So about 2 times a day I charge my phone. Is this healthy for the battery or does it not matter? I'm trying to get the most out of my battery. I seem to burn about 3-4% per hour with it just sitting on desk. Thanks for any advice!

Nothing wrong with that
You are charging twice a day though so you will half as many days until your battery dies. Still a couple of years until it reaches 80% capacity though

Well yeah, but don't worry about it. You'll get another phone by the time you notice a battery drop on this phone.

Ideally you should be charging the phone when the battery gets down to around 40% and charge it to almost full, 97%-99%
Sent from my HTC One using Tapatalk 4 Beta

I've always felt that the less you charge s phone, the better in the end. And once its done charging, unplug it. So don't leave it charging over night. I have a timer set up so my phone charges only for a few hours a night then shuts off. When I wake up, my phone is usually in the 90%+ range

That's simply not true.

Lithium-Ion batteries are designed to be used - not to be used as permanent storage (thats why batteries in always-coorded laptops die faster)
(storing li-ion batteries should be done at 50% charge, never 100% nor 0%... )
Li-ion batteries should never get below 30% and likewise never hit 100% - The reason why, is because you are stressing the battery the most in the extreme ends... an almost empty cell is stressed when it has to deliver .. and an almost full cell has to charge at higher voltage to reach 100%.
So the best thing you could ever do is to charge from 30% to 95% if possible.
Regarding the amount of charges... with Li-ion you shouldn't think about the AMOUNT of charges, but the SUM OF HOURS that your charge..
so lets say you charge 500 times a year and you in total charge for 500x4 hours = 2000 hours of charging..
the battery usually last for 5.000-10.000 hours of charging ..
The reason why it is so, is because charging li-ion burns the Kathode (or Anode, can never remember) -- and when its all burned off, the battery wont charge anymore ...
Discharging too fast, also burns the Kathode (Anode) !!

Everyone is all over the place in this thread. The two things I will tell the OP to do is not leave the phone plugged in over night, and stay away from 100 and 0% and you will be fine.
But even if the OP keeps treating his battery the way he says, it will be okay. Not ideal, but still okay.
I personally try to keep the phone between 30-80%.

you found the right source... its were i get my facts from...

Does the HTC One battery stop charging after it hits 100%? There for no longer having the issue of over charging?

[Q] Battery drops to 95% once charged fully?

My problem is that after charging to 100%, the battery drops to 95% after the course of about 10 minutes after unplugging the charger.
After reaching 95% the percentage would 'normalize' and discharging would occur on a more regular basis.
I have been experiencing this problem for the last 2 weeks or so.
It started happening suddenly, can't remember doing anything out of the ordinary to cause it to happen.
I tried letting it discharge to 1% then charge fully but the problem still occurs.
Even tried this app but still the problem exists.
Tried about 3 different ROMs also but still a no go.
Any advice about what can be done cause its driving me up a wall?

It's a known base bug and the only way I can think to 'fix' it is to charge your phone while it's off. I turn mine off when it's nearly fully charged.
Seriously nothing to worry about.
It's been reported many times now if you had used search

Ok thanks. Will try charging with the phone off.
I am curious however how this started happening without me doing anything unusual.
I mean prior to this happening it was discharging normal.

It use to bug me too but I've had the same or better battery life in the end so it's all good.
Started happening when 4.3 base was introduced

Try discharging completely, then charging completely while the phone is off, then start using it normally without intermittent charging. See how that goes.

What I find is I leave my phone and plugged in for at the very least 10 minutes after it reaches 100% and only then does it discharge normally.
Asides from that my phone also drops to 95%

Didn't realise this problem was so prevalent.
Becoming less bothered about it now.
But will do a full drain and charge with it off on the weekend.

I have the same issue and I usually do what "Jonny68" does and it works
I've read somewhere that it is intended like this by hTC to protect the battery

Tried the charging while off option, didn't let it discharge to 0% however but that seems to have worked as I finished charging about an hour ago and it is still at 100%.
Thanks everyone for their contribution.
