I have NEVER EVER had a phone that took so LONG to charge up!
Is it just mine? Maybe it's defective? What on earth did they do?!
Takes probably like HOURS to get to 100% with the screen, bt,wifi OFF!
And what's crazy is that after the phone says it's fully charged I unplug and the battery meter drops to 96-97%%. THAN it takes more time to get to 100% again.
If I didn't like this phone so much I take it back so fast!
Does you phone take really long to fully charge?
The charger is slower. This helps extend battery life typically.

Really? Didn't know that. Can I get a faster charger then? I'd rather my batter charged in 20 min and have to get a new battery every couple months than have to wait nearly four hours.
Other than that I'm loving this thing.
Do you not charge it when you goto bed? When I wake up mine is fully charged. I don't check to make sure its 97% or anything like that, but when I goto bed its been known to have around 70%.
Of course mine is coming off the charger at 6am and I normally goto bed around 10:30-11:00pm.
As for charging a battery for 20minutes and having it full I've never seen that in any phone I've ever owned. You could buy a quick charging car plug, but personally I wouldn't recommend it for charging all the time.

Of course I do. But I use my phone way more than most people. So I have to charge at least once during the day. And that takes forever. I'm going to have to buy and extra battery with external battery charger to just SWAP!
Glad this is "normal" thought my phone was defective.

Well I'm coming from a old phone that would charge to full in about an hour and be functional for 3 days. I didn't expect that with this phone (with the sweet screen and processor) but I am barely making 24 hours. I don't have GPS or Wifi on all the time and keep my screen on a low brightness setting. I AM playing around with it all the damn time though.
Anyway a normal charge at night works most of the time but it's good to know I can get a faster charger for the times when I need the power right away.
Also, any way to see the battery usage for the life of the device?
That's a smart phone for you. Never had a smart phone that would last more than 2 days tops, and that's with light use. But with moderate to heavy use,a day is it, maybe even a quick charge in the afternoon depending on how heavy the use.

If the Nokia e72 is considered a smartphone that phone lasted for days!
I know it has a small screen and all that but still, the battery was AMAZING!

Has anyone else seen this? From 100 to 90% the power just drops almost instantaneously but after 90% its normal.
Already been brought up, a lot.
Apparently when your phone charges up it stops once it reaches ~100% and begins discharging, even though it is still on the charger. People will turn their phone off after a full charge and charge for an additional 20min to an hour before they get another green LED. People have reported much longer battery life when doing this, but it is a pain in the ass.

Ahh interesting. I thought I was running into an old winmo rom flashing issue where if you flashed under 50% battery life you could never charge the device above that point.
Yea it sucks but it works... I just ordered an external battery charger since I have 2 batteries now so I don't have to do this anymore

Hmm i tried and it acted the same way.
Apparently the HTC models act like older phones did back in the day. What HTC needs to do is put something on the phone face itself when new that says "CHARGE FOR 4 HOURS BEFORE INITIAL POWER ON FOR MAXIMUM BATTERY LIFE."
Once you do this once you dont have to keep doing it. I also powered on my phone the minute I got it and activated it without charging it first and I was seeing this issue until I did a power off charge. The phone runs from 6am to 11pm without an additional charge cycle in the day and that is a huge improvement for me. I was charging the phone twice to three times daily.
It takes me any where from 2.5 to 3 hours to charge my fone.....no way is that rite....is there anything I can do about this ....

If you want to wipe the battery stats so you can make sure you are getting 100% out of your battery use the phone till it dies all the way and it turns off. Then turn it on and use it to till it dies, and repeat that process till it will not turn on at all. Plug it into a charger and turn it on & boot into bootloader > select recovery > advanced > wipe battery stats > reboot system and let it charge for at least 8 hours with minimal use.
@kim, charging the phone for that long will not have any ill effect on these batteries. They use LiPo batteries which are extremely different from previous phone battery designs. Our phones actually have a programed system that will cut the charging back and turn it off as the phone battery reaches the max. Once it reaches the max the phone will not charge the battery. When you battery gets HOT from charging is when to be worried. Heat and overcharging (which is next to impossible) are the two biggest killers of LiPo batteries.

I only know this because i use LiPo, NiMH, and NiCad batteries in my Electric RC cars. Been into that hobby for going on 20+years.
Takes about 2.5 hours for my phone to charge fully from 0%
The battery ages, and the time it takes to charge it goes up. Perfectly normal.
if you take the battery out and shake it for about a minute it will charge faster.
Are you kidding? haha
yes lol was wondering how long it would take for someone to speak up.
I think it is actually healthier to charge the battery slowly. Fast charging heats the battery... 2-3 hours seems reasonable.
And of course, shaking does not help- without the ice

I recharged my Galaxy Tab 10.1 yesterday from a 15% remaining charge.
I powered it off and used the wall charger. It took almost 6 hours to charge to 100%!
Is this normal or is there something wrong with the battery?
Thanks!
Mine was slow at first too. But now seems to have gotten quicker.

What is the rating on the charger that comes with the unit?
The rating is 5V - 2A
Yep, noticed it took about 3 hrs to go 40% charging. Not sure why there is such a drastic difference from the Xoom which could charge from 10% to full in little over an hour with similar drain to GT.

Can you please quantify what quicker means?
We have a rather large battery in the device, while I agree 6 hours is abit much, it should be quicker at 2 amps.
On the other hand, I sit in on the charger at night before I go to bed. I am definately a heavy user as well, and the battery lasts me all day with atleast 30 to 40% left over by bed time (this includes a 1.5 hour commute each direction using Waze, the GPS, and wifi tethered to my phone, 2 gmail accounts polling every 15 min, web surfing throughout the day, and playing games during my morning and afternoon constitutions .. I know.. too much info)..
So I can live with a longer charge time, at least for now..
I charged my GT Tab completely before using it the first time. Then I drained it down to about 9%. I timed my first full charge from 9% to 100%, it took exactly 6 hours and 4 min. My Xoom charged in half the time. I am hoping it gets better like I have heard from different people.

i believe the xoom's charger is 16watts or more. i can't really remember, but it's got the highest rated charger b/t the xoom, tf, and gt10.1.
I think that's just wishful thinking on their part. How does a battery suddenly learn to charge itself faster. You make it sound like the battery is a muscle you can work out. The thing takes forever to charge but it also has excellent battery life. So as long as you don't find yourself in a hurry to travel without time to charge the battery should last you almost all day.

I charged the device fully before use. Used it down to 10%, plugged it in and charged to full powered off. This took around 6 hours. The second time I charged it from around 14-15% It took about 4 hours. I have charged it twice more since from almost zero, and it's taking about two hours.
Remember the math:
7000 mAh battery
2000 mAh charger
That means from drain to full if the screen is off, about 3-4 hours. If you have the screen or device on and it's doing anything, it's using some of that incoming charge, so will increase to 4, 5, 6 or more hours to fully charge.
Gets even worse if using an aftermarket charger, say a 800 mah or 1000 mah charger like the iPhone or Kindle charger...can then take 10-14 hours to fully charge, hehe.
It's funny how people say it charges quicker after a while, when that's not logical, you just don't notice it as much going from 65% to 100% as you noticed when it went from 15% to 100% the first time, hehe

Smaller battery=shorter charge, a 2 gallon gas tank is quick to charge too, hehe.... kidding.
But seriously, Samsung is bad with their charging. My Samsung Infuse and my Galaxy tab both take forever to charge.

Did I read it correctly that if recharged from almost 0 (e.g. <5%?), it takes only 2 hours to go to 100%? This seems counter intuitive.

i think what happens is that as the battery calibration gets more accurate it finds where to quick charge and where to trickle in the appropriate levels.
Hi people... i think that Samsung has got a little of troubles of making batteries and charging philosophies.
I has got two devices that are the last technology from samsung, the nexus s and the galaxy s2 right now.
The nexus s has got a very strange trouble (until now not fixed) that battery never reach full 100% state in charging. And much very very long charging time.
The Galaxy S2 reach 100% but takes too much time to charge. It's possibile that never one has think about modifying this?
Where we can start to mod this ? Inside the kernel? Inside bootloader?
I think it's not only a mine trouble
i think its the battery charger not the phone, which makes it so slow

Mine finishes very quickly. about 1-2 hours when it's at 25 percent. And you cant fix charging. Remember that it is a big battery.
Ever tried using an adaptor for a device that has a lower rating than the adaptor? Ever heard that pop and the smell that follows?
Learn to be patient. Last thing you need is for the battery to blow up and destroy your phone.
protip: turn off your phone while you're charging with AC and not USB.
it could be your USB (and by extension, your PC) is not providing enough power to the USB ports. It happens.
My phone charges in 4 hours with AC when the phone is off. 5 when on.
6 hours on USB, phone off. 8 phone on.
It can be "fixed" in the kernel.
Samsung made it charge slower so that it charges better.
Faster charging = more heat = more dissipation, and potentially other problems.
Even though its a safety feature, its ridiculously slow. Phones takes AGES for a full charge.
these new phone are strange
my old i8910 HD charges full in like 30 min
and stays without a charge for 3+ days
Mine charges slower than htc but no too slow.. I'd say 2.5 hours full charge

Do you guys not get more than 3-4 hours of sleep?
Do you guys exhaust the battery to the point where the phone turns itself off before plugging it in?
Can you not plug your phone in before you go to bed?
I always plug my phone in before I go to bed (usually with 10-20% remaining) and I don't remember a time where I wake up in the morning and the phone isn't 100%.
I'm not trying to be cynical...just curious what other people's routines are when 3-4 hours to charge a phone becomes an issue.
A complaint like this wouldn't even cross my mind.
I need a faster charge too. Not because I'm impatient but because the phone can use more current then it can charge, especially during car navigation.

Well, the issue here is obvioisly not when sleeping (and yes I slept 3 hrs last noght and got a full charge...bit when on car or @ work, lunch time etc...those little precious weird moments u get in a daily basis when u arent using ur phone and got a charger at hand....maybe it would be possible to make an app which would allow toggling fast charging or slow charging, that way we could have both....fast ( on the run) and slow (night) modes....that would be really nice......but wait....winmo had this remember?
Hi.
When i go to sleep after a normal day my battery is around 60%
Yesterday it was only 85% after a full day of usage.
I sleep around 4 - 5 hours at night. That is how long i charge my phone, its allways charging when i sleep.
But is it bad if my phone is charging for so long even if my battery was not complete empty ?

wow. That's great battery. I also usually charge my phone overnight, but I have <10% when I charged it.
I think it will damage the battery somehow, but I can't confirm this, many people have better battery knowledge rather than me, so just wait them to answer it.
But I wanna give suggestions, if your full day use is just consume max 40% batt, just put it in flight mode or turn it off overnight, so you still have enough juice for the next day.
I think it's more battery friendly rather than charge it overnight while still have alot juice in it.
I think it's better to put it in ultra power saving mode instead so you won't miss any important calls or texts.
It is lithium, replaceable battery. Either enjoy it fully charged or buy spare battery and craddle/charger to replace dead one when needed. It only will last so long and you may need replacement in about 2 years anyway.

no its fine. if you want to increase charging time get a Qi charger which takes 5 hours to charge anyway.
Not much to worry about when the battery is user replaceable. You'll be fine, but even if you're not, you can get a brand new OEM battery for 30-35 USD.
No it isnt.. I have 3 years old galaxy s3 i have been always charging it overnight.. Still no issue.. Working good
