Guys my SGS2 is taking around 4+ hrs to charge from around 5% left. Is this normal.?
Yep takes 4 hours here too

What's the rated output on the wall charger?
I think this is by design as the phone already gets extremely hot when pushing the CPU (gaming etc).
I believe this can eventually be changed with custom rom/kernel.

5v @ 0.7A, by the looks of it this is normal.
thanks for responce peps. Never had a phone that took so long to charge.! Normally about an hour which is why i thought i may have had a problem with the handset.!
S2 stock Optus KE2 with it remained turned on with wifi, email checking etc using Energizer XP8000 battery as power source for charge went from 24% reminaing to 100% charged in ~2hrs. S2 internally seems to limit it to <700mah charge rate.
Find a Iphone4 charger or something similar it will give you 5v @ 1.0A, charges quite a bit faster, I use that at work then the slow .7 at home.
my XP8000 charges at 1000mah but S2 will limit it to 700mah
I think you could charge the battery alone in a dock. There it should load with the full 5V and 1ah..

Ah forgot about that. But it's kind of pain removing that battery cover.

Anywhere you can back this up? I seem to have faster results using a 1.0 vs .7, showing that it is getting more power.
It's been mentioned a few times across various forums. But i'm just going by my experience.
It also takes me around 4 hours to fully charge from below 5% battery. However, if I turn the phone off whilst it charges, goes slightly quicker. Obviously.
Hi,
I think the recharging time is quiet normal for such a phone (and battery).
I had to charge the battery of a friend's phone these days with my notebook.
And it took some hours from 30%. (HTC DHD)
About the same for my SGSII.
I think thats normal.
what would we do without electricity?
Dead phone that is fully discharged battery phone off stock charger to 100%
sub 3 hours .

Changed handset yesterday. today charged new phone from 5% and it took 3hrs 4mins. So it looks like i may have had either a dodgy charger or batt.
I am charging with supplied charger(5V / 0.7A) ...
During the charging I turn off my phone but the charging time is still 3-4h -.-
Mine has been taking forever lately, just took over 5 hrs to gov from 25 to 100%...WTF! My Hero with the 1500mah battery would charge from 10% to 100% in 1.75-2 hours this thing has a roughly 17% bigger battery but takes 3 times as long now to charge, it didn't at first when i got it but it is now no matter which of my 3 HTC wall chargers or my car charger I use. I don't know if the battery is going bad or what. Is there an app for displaying charging amps...I thought I read that there was but i can't find one?

I use Current widget (free in market).
Cool Thanks, wonder if that shows amps comming in to phone or just +amps over what the phone is useing...by the fluctuations I would say the latter. Works though.
That Current Widget worked great, when unplugged it shows draw and when plugged in it shows gain rate. Note for everybody, just because it sais its a High Speed 2.0 cable doesn't mean it meets the amp draw requirements. 2 of my skinny cable are only capable of transfering 500mah when the HTC cable and 1 of my thick ones transfer a full amp of juice. Good to know all my chargers work just have to get a thick-high quality 6ft cable now.
I've had my new HTC Amaze 4G for 4 days now and absolutely love it, what a great phone! The battery life is great (I'm careful with all my settings) and I'm only finding issues with the charging TIME.
It's the second time I've charged it and after noticing how excessively long it took the first time, I clocked it this time and it took 4 hours and 45 minutes. I used a charger that I've used on many other devices with no issues (5 volts 1 amp).
The battery level increases 1% every 3 minutes, which adds up to 5 hours. I calculated this both with the screen on and by averaging out over a longer period of time with the screen off. I also tried with the phone completely off and the results were the same.
I made sure there were no processes hogging up processor time or excessive RAM usage.
When I go into to "Settings -> About Phone -> Battery" Battery status clearly states: Charging (AC).
I have also read somewhere that this can possibly be set this way by design (possibly to prevent the battery from heating or overcharging and saving its life in the long run).
I also realize that the phone is new, and the battery needs a few charges to be settled, but 5 hours to charge on the second charge just seems like too much.
On the HTC product support website, on the faq there is the following question/answer:
How long should it take to charge my battery?
"Your battery can take up to 4 hours to fully charge using the AC charger. It will take much longer using the USB as that is the trickle charge function."
Can anyone out there with an HTC Amaze 4G confirm how long their phone takes to fully charge from the AC charger?
I'm thinking/hoping this is a defective device/battery/setting...I don't like having to wait 5 hours to have my phone fully charged.
Thanks in advance,
Filipe
Ok, I'd like to add one more thing. I finished charging the phone last night (about midnight), by the time I went to bed (around 2 am), after barely having used it, it was still at 100%, now at 9:30 am (7.5 hours later) the battery level is at 95%. I had everything off and very little background services and apps running. Even the network type, is only set to the basic, no data connection was live/standby.When I check the battery status/histogram this is what I get:
-44% went to Cell Standby
-42% to Phone Idle
-8% Display
-6% Wifi (I think I used it before I went to bed, but turned it off right then, and it remained at 100% battery)
I'm not too happy...this can't be right...it shouldn't take 5 hours to charge and discharge this fast? Can anyone shed some light please?
Thanks
Come on....anyone? Please? This is driving me nuts!!
Yeah that sounds about right. Don't complain man. Your battery life is pretty good compared to other devices. My device takes 3 hours to fully charge and can last 24 hours with minor use. Just charge it when you go to bed and you won't notice the time it takes
My desire hd takes almost as much (Around 3 hours) and my Optimus 3d prolly takes even more (5?) to fully charge from a full discharge...
(With Stock HTC/LG Charger. The HTC's AC Adapter is 5V/1A [Shouldn't that charge a battery in under 1 1/2 hrs?]. Not too sure about the LG)
They take Much longer to charge on Computer/Laptop USB Ports. The Optimus 3d actually loses battery while charging (With screen on) with a USB port.
Also, 5% a night is pretty good. My desire hd goes down 3-5% per night (2g, no data enabled.) or 0-1% with Airplane Mode. (Rooted, Revolution 6.31)
And my optimus 3d pretty much runs out of battery in <100 mins with full brightness while Playing Games - It goes down more than 1% per minute depending on the game being played, especially if 3d Converter is used. This is pretty much the same for all GB/Froyo ROMs.
Just charge it when you go to bed and you won't notice the time it takes

I Agree. Both phones usually last around a day at least for me. You could always try a battery monitor such as GB Battery Stats or watchdog (The CPU One). CPU Intensive applications and Awake time during sleep are usually what cause bad battery life. Faster chargers such as 2A ones should also charge the battery faster, but they might reduce the overall battery life.
I would suggest buying a wall charger and cheap batteries from ebay. They last almost as long as stock batteries and cost only ~$2-4 each. [They apparently explode though. Never happened to me.]
-------------------------------
Both phones seem to charge from 0-90% much faster than 91-100% as well. I'm not sure why, since 100-90 wastes just as fast as 90-0. (Charging from 90%-100% battery practically takes a third of the full charging time)
many thanks
RESOLVED (Sort of...lol)
Thanks for your feedback guys!
I just finished charging it this morning, and it's FASTER NOW!
Took exactly 2 hours and 37 minutes (Battery Moniter is a great app!).
I think it actually may be due to the phone having some sort of smart charging system which "looks after" the battery. Since the phone is new, it might be wanting to start it off with some slowww charges and gradually speed them up.
But I still have to narrow it down some more since this time I'm actually using the supplied cable and charger (the ones I tried before were also 5V/1A).
The cable I was using (had it for a while now) had a pinch or two, it didn't look that bad, but I'm thinking it could also be the cable (could be shorting)!
I'm gonna do some testing on this cable now and report back my findings!
Thanks again!
RESOLVED!!!
Ok, so it actually turned out to be the cable. I really feel like a dumb ass...lol. Oh well, at least I figured it out!
So yeah, one good way to see if your cable / charger is good is to use Battery Monitor, and on the main screen where it says your device is charging (AC) and etc..it will also say the actual amperage (in mA) being fed to the battery...that number should be within the 500 to 750 range, if its lower, there is likely something wrong. (Mine was at 16...lol).
Thank you all for your help!!
Cheers!
can you explain to me more !!! i just had the phone and the battary run out like 5 hrs after ,,, what s about your cable-charger problem i didn t get your point !!! can you help me plz

My problem was the cable, and it was causing the phone to take five hours to CHARGE, not discharge.
These phones don't hold charge for too long, and the more activity you got going on, the more power it will consume. The screen hogs up the most power, so using the device constantly (especially with high intensity background light) will drain the battery very quick. First smart move would be to set the screen intensity to the lowest setting. Wi-fi and bluetooth, if you're not using them, shut them off. Open your task manager (or get a decent one from the market) and kill all the apps you got running in the background.
Games also require a lot of graphics/processing power, so naturally they will drain a lot of battery too.
Edit: There are some special cases where it could also be related to your network or even simply coverage zones exposed to the device. If it's stuck in a zone where it has weak 4g and 3g signals, it will keep bouncing back and forth causing more drain than normal on the battery as well.
If you've taken all these things into account, then you may have a defective device, then you will want to setup an RMA...or just take it back wherever you bought it and ask to exchange.
Hope this helps,
Cheers
My skyrocket takes about 3.5 hours to charge from 10% to full charge. If I plugged it in the car charger and run google map with the radio on the background, it would slowly drain the battery even though it was plugged in. My iphone 4 did not do this. It charges very fast and does not drain the battery even when I had several apps running in the background. I think the skyrocket consumes more power whether it is plugged in or not.

Hi, what you need is a charger with a higher amperage rating than 500mA (or 0.5A). Buy a charger that is rated for 5V/1Amp like this one and your problems should go away.
The phone is basically "burning" more energy than it is receiving from the USB charger, hence the discharge.
To know the amperage rating of your charger look on the label for numbers that look like "5V/500mA"...
Hope this helps,
Cheers
EDIT: The link I provided does include an iPhone cable, but I'm just referring to the charger itself, the cable would obviously have to be a micro-usb.

Most illegal threads are trying to move from Mexico.
But, you need a charging source more powerful then the base 500ma, (or whatever that term of measurement is) computers are only supposed to supply 500ma to a USB port so AC adapters are typically better for charging. But feel free to follow the post above and check the rating on the charger.

Make sure to use the original charger and cable that was supplied to you by T-Mobile/HTC
I noticed the 12-pin cable is faster than the 5-pin.

Sounds about right. If you want better battery life either root it or buy another battery.
To get really good battery life ?...you got the wrong phone man.

I have my phone plugged into my PC at work all day (USB) and rarely charge my phone outside of the office. Is this bad for the battery/phone? Anyone else do something similar?
I also did this with my OG EVO and battery life was 'okay' but never fantastic.
I know that the EVO 3D charges to 100%, then stops charging and drains itself about 5%, then charges again back to 100% while it stays plugged in. Maybe HTC kept this charging method?

Errrr....I don't think its possible to charge faster of a USB, that the wall outlet. .5 amp from USB vs 1amp from the wall.
But I usually let mine drain to about 50% then charge it off USB the rest of the day.
It's not really bad for your battery, but it's not the best practice for a li-ion battery. The subject of how to best take care of li-ion batteries is incredibly complicated and ultimately way over my head, but speaking in general terms, two things that are always bad for your battery are voltage and temperature. leaving your battery on the charger exposes it to both (although to a lesser extent on a USB charger than an AC charger, since you're getting half as much current). when the battery is at a lower capacity, say 80% or so, the voltage going through it is probably closer to 4.1 or 4.0, as compared to roughly 4.2 when it's at 100%. anything higher than 4.1 is considered high. Deep discharges also tend to reduce battery life, so if you really want to eke every last drop of life out of your battery, I'd charge it up to full, take it off the charger and let it get down to 50-40% or so, and then start it charging again at that point.
There's lots more information available at http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries if you're interested; they go into a lot more detail.
Thanks for that post. It says to charge your battery more often is better and that full discharging is not good. I fit that pretty much as I use my phone 90% of the time at work and have it plugged in to USB. After work and overnight my usage is light, and my battery may drop to the 60-70% before re-charging it the next morning at work.
My biggest issue is over the weekend and letting it discharge too much.
One thing to note, is the battery in the EVO LTE is Li-Poly.
I've noticed many roms provide options to charge at a faster rate, many have by default now.
Just looking at CheckRom, I see that it states "(for AC: up to 1200mA, for USB: up to 900mA)". Is there any real downside to using these? Such as shortening battery life.
I have been wondering about this for awhile. Thanks.
I'm sure I read somewhere that it will only use the milliamp that is supported by the battery. Also if it charges faster it shouldn't be a problem since its using the correct power input

Faster charging equivalents more strain on the battery and thus a shorter life in terms of charge/discharge cycles.
Since the battery is replaceble, it may well be worth the few dollars to you to have it charge faster, but that's personal preference.
Quick-charging batteries leads to additional heat, I would thus not recommend it if you plan to leave it charging in a car in the summer
since that will cause even further strain. (It's very unlikely the battery could go in self-heat mode due to charging)
Actually NO, but charging with more than 1A which is stock/default will add more heat to your phone. Heat which is HOT not WARM will reduce battery life of rechargeable batteries.
Oh right, very neat. I plan to get one of those high capacity batteries (tad over twice of original) for $15.
Does anyone know if it can also reduce battery life leaving it on charge all night? I think it discontinues charging.

As every one said charging at higher rate will reduce battery life and also reduce back up time.
Secondly, leaving charger ON all night will not effect battery, because charging is cut off by internal circuit once battery is fully charged.
