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!

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.

thread moved to...mexico?
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.

It was around 36% when I was able to access the battery meter following initial startup.
Only took 3 hours till full charge over USB to Wall outlet.
Is this because the USB to Wall outlet is faster charge, and that the 8 hours suggested in the manual is for USB to PC charge?
I don't have my prime yet however, you need to let it charge for 8 hours, even if its fully charged. This will condition your battery. Your manual also states to let it charge 8 hours.
Personally, I think the whole "charge for 8 hours" thing is bunk. No idea why ASUS recommends it, and I can't remember any other manufacturer ever recommending such a long initial charge. I think ASUS just does it to be sure people charge it completely before using.
I mean, seriously, if ASUS was that worried about it they wouldn't design the Prime to turn on when first plugged in. And, I imagine that once the battery hits 100% (signified by the green charging light), there should be a cutoff. So I'm not really sure what charging for 8 hours (or, yes, about 5 hours after it hits 100%) accomplishes.
another reason I love this tab so much. it can go from 0%-100% in 3 hrs. my Ipad takes more than double that time to get full charge. maybe not that long...lol but you know what I'm saying. this also may hold the title of fastest charging tablet.
thanks guys im going to finally go mobile then. Its even showing 100% too.

Every manufacturer recommends 8 hours AFAIK in their manual or support etc. This is to condition your battery and improve its lifespan. I've had a phone which I didn't charge for 8 hours on first charge, battery life completely screwed up within half a year.
Once it hits 100% you're good to go. After that it will stop charging for a bit then charge after a certain percentage drop. There will be no benefit to charging it after it hits 100%. With Li-Ion technology the whole battery conditioning thing is overblown anyways, these aren't old style NiCd or NiMH that need full draining and full charging everytime and storing with certain charge levels.

What is the best way to save the battery life, and made a charge lasting longer?
How long should we wait before recharging the Prime? I always wait until it reaches 20-25% before recharging.
I do this about every 2 days, and when I do not use it it's standby if short pause or shut down at night.
I saw a thread somewhere in the forum but could not find it.
I do not use +IPS and brightness is about 20-25...
Not gaming, just surfing and testing Skype with WiFi (BT is not good with WiFi) so it's off
Any help we good suggestions?
Thanks

My charging habits are:
To keep the battery healthy, keep it cool, I almost never use the tablet while charging off the wall and always turn it off. I've checked the charger brick temp with an IR temp gun and the brick stays 10 to 15 degrees cooler while charging when my Prime is off. This will save the charger.
I usually wait until I am almost drained, usually anywhere from 1 to 20%. With lithium ion batteries there is no "memory" that develops so no worries there. Temperature is the mail killer of Li batteries. You can charge it any discharge state, again Li batteries don't care. I did an experiment and when the Prime is over 95% Even if you put it n the wall charger it doesn't charge. Once it drops below 95% it starts charging. Remember, this s MY Prime, your and everyone will be slightly different depending on the battery and how the software and hardware interact to provide battery conditions (temperature and %).
The dock changes the equation since it probably charges the Prime and a lower current then the wall charger so you can use it while charging. I don't have the dock so I cannot confirm this though. The Prime will charge of the PC USB but ALOT slower and the Prime has to be turned off
This is the way I do it. Everyone is different though.
Thanks,
I always shut down before charging, but it turns on on its own.
Always use the charger, never USB/PC
Yes I wait until 20%.. Temperature, well I never noticed an issue
The house is warm about 21 C, and I never use it in cars or outside.
The dock is not used too much, only few time, and even full charged it seems to drain pretty fast not in use.
I just ask because I can see that WiFi, brightness and standby are main cause for draining.
I cannot measure how long it lasts, and it's not an issue.
The question was just becaus a charge every 2 day.. normally is not a good way to preserve the battery.. But I am ignorant about this matter.
Charging time does seem to vary a bit. I would just charge your prime based on your needs. Li batteries have no memory, so charge it when it needs it. If you do leave your prime in the car, let your prime either warm up or cool down (or in other words, reach room temperature) before connecting to your charger.

I think I know what the problem is: Your phone is trying to kill itself and save humanity from that terrible font
seems like a bit much but it could be normal.
Once your phone's charge reaches 100% it stops charging to prevent damage to the Lithium-ion battery. I am not sure however when it starts charging again.

Are you using the Samsung OEM home charger? It shouldn't be dipping when using that one. Mine will charge AND increase while using it in the car with GPS running (huge battery drainer) and a driving DVR program (DailyRoads Voyager) and the screen on. All with a car charger and cheater plug that shorts Pin 2&3. That's the secret to getting rapid charge to work. The OEM home charger has those pins shorted internally. If you are trying to charge over USB on your computer then again you need that cheater plug and ensure the USB port can support more than 700 mA. If it's a USB 3.0 port then it should handle that current.
No problems for me on the stock or aftermarket chargers with the screen on.
I have the same problem with my brand new I717 GN. Battery level slowly drops when on charge, even if it's the OEM wall adapter. I've tried my Kindle USB cables as well with about the same results. I noticed the charge is a bit stronger from the wall source, but still can't keep up with even simple web browsing via WiFi. I've installed JuiceDefender as well, and it's helped reduce depletion a bit, but not really enough. This phone would never last me a full day of intermittent use without a power source.
I've read several of these threads and there doesn't really seem to be a solid solution to this other than some GN owners saying they have the problem and some don't...
Someone mentioned a crosswired 'Smart Adapter Compatible with Samsung Galaxy S' on Amazon (I'm too new and can't post the link)... I might try that but maybe I'll return for a new one if some people don't have this battery problem, unless it turns out to be a latest firmware problem..?

I read an article in a journal recently about how smartphones charge their batteries. The article claimed that once the charge has reached 100%, it will stop providing current to the device until it reaches 90%, after which it will then trickle charge to maintain it at about 90%. All the while the battery meter will still show 100% (at least in the case of iPhones), but after you unplug the phone the first 10% will go rather quickly as it approaches the real charge level.
True for our notes? No idea. But with how Lithium batteries work, I wouldn't be surprised.
I haven't gotten my Note to discharge while plugged in with the OEM AC charger. In the car however, running Waze will suck the life out of it even while charging. (My car charger puts out about 150mA less than the OEM AC charger). Oddly enough, running Navigon on battery alone has less discharge than running Waze while plugged in...Which sucks, because while Waze has crappy directions, it has saved me many hours by routing around traffic. But at least the phone still charges while using Navigon and streaming some Pandora.
Hi everyone i have been using wifi 5.0 about 3 months now it satisfied me enough and i am sure will continue. But the only issue which makes me unhappy is when i am gaming or using gps battery finishes rapidly. I would like to learn when to charge the device is 25% ok and when i am using it on charge even when its full is it bad for the battery life?

don't leave it on the charger longer then 20-30 minutes after it reaches 100%, any longer can be damaging to the battery if done repeatedly.
Wish these chargers were more like the motorola ecomoto chargers that cut off charging automaticaly once the battery hits capacity.

stopping charging has to be done within the charger itself, so no there is no app that can stop it, plus apps couldn't do anything when the device is powered down anyway.
An hour of a game kills your battery? I can play atleast an hour probably closer to 2 of angry birds and thats from less then 30% and i'm on the 4.0 player which has a much smaller battery, sounds like you've got some battery drain issues to work thru.

yeah u are right about apps no way any app to work when the device off.
I mean maybe 1h and 20 min. with 50% brightness on and i guess fifa use more data than angry birds when ur playing.
anyway its important to know that i shouldn't keep charger on when its 100% because usually when i am home i was using it like that thanks again.
do u think the app called 'sense analog' may make the battery life shorter.
Something is definately wrong, because I can play MC3, which is even more intensive the FIFA on my Gplayer 4.0 for more than 1.5 hours and still have some life left, and the Gplayer 4.0 is only rated for 4/5 hrs and yours is rated for over eight!
After a full recharge, while still plugged in download battery calibration from the market, and follow it's instructions, after you do, while STILL plugged in, reboot. After a full reboot, unplug it, and DO NOT REBOOT until your gplayer completely dies (forces shutdown). Once that occurs, plug it in, let it charge to 100% (while on), leave at 100% for about 15 minutes, unplug, and use as normal. That should fix your issue, unless your battery is dying, which should not occur, even if you are abusing it badly, for awhile longer.

haven't seen the 5.0 screen in person but if the brightness levels are anything like the 4.0 why do you have it so high? My brightness is at like 15-20% with autobrightness OFF.
First, like many others already said, it sounds like something is wrong with your battery. I'm on a 4.0 and playing two hours of a really intense 3D game with auto-brightness indoors will bring the battery from 100% to 50% (maybe it even uses less battery).
Second, as to how to conserve battery life, Rule #1 (as others have said): definetely do not keep it plugged it at 100% for too long. Then, something I tried on my iPod and have been using ever since: keep the battery between 50% and 100%, and once a month, completely empty the battery (until it shuts down) and after that charge it to 100% (this is called a charge cycle). As to my iPod's battery, before I was using this, the battery life got shorter and shorter, but after, it didn't shorten noticeably anymore. On the computer I'm writing this on, for a couple of months, I barely followed this plan, and I lost about 5% of my battery capacity (I have a battery widget that tells me what the total capacity is) within one or two months, but then I started following it a little more closely, and actually got some of it back. Over six months later now, I have lost about 10% of my battery capacity (from the original capacity), except that I should do a charge cycle in the next couple of days, and the last time I did a charge cycle, I got about 5% of the original capacity back, not to mention I have broken rule #1 probably too often and for way too long, often for several hours
My 5.0 can play games for hours before it dies but it has strange batery levels..From 100% to 75% it goes very fast.around 40 minutes when you play game..and then on 75% it stays there for 2hours when you play game and with regular use it can stay all day on 75-70% ..after that it fastly drops to 25% and just when you thing you need to recharge it can stay on 25% forever..you can play 2 more hours of game on 25% or with lighy use it will stay all day on 25%.

This is not correct. NO modern device has ANY smarts in the external charger - nearly all current phones (and every smartphone on the market for the past 3-4 years) has a constant voltage 5.0 volt USB input. Modern "chargers" are not chargers at all - they are dumb 5 volt power supplies, nothing more.
Charging "smarts" are handled by electronics in the device itself and have been for ages. (For all practical purposes, the Player 5.0 is a Galaxy S smartphone minus the cell radio...)
The kernel and charger hardware automatically handle charge termination and restart themselves. This is, for example, why Daily Driver can charge at higher current levels than stock at low battery (but drop the current as the battery reaches nearly full in order to stress the battery less).
Oh, as far as battery percentage display - the method used for estimating state of charge on the Players is abysmally primitive and highly inaccurate.
Battery Charging YP-G70
I always charge my completely standard YP-G70 overnight. As I understand it, the charger only provides voltage and in this case it's 5vdc. The device's battery management software draws the required current to charge the battery. If you install 3c's "Battery Monitor Widget Pro" you can see a charging graph showing the current levels drawn over the full period of charging. The charging current is stepped to control battery temperature and is reduced as the battery approaches full charge. By the time the battery reaches full charge the current draw is down to a trickle charge and will not overcook the battery. I usually leave the device switched on, which further protects it by maintaining a small load. One of the problems I have found with this device is that this charging regime, along with the fairly large capacity of the battery, mean that the battery can take up to six hours to fully charge, which confirms, in my view, that overnight charging is OK.

Something is definately wrong, because I can play MC3, which is even more intensive the FIFA on my Gplayer 4.0 for more than 1.5 hours and still have some life left, and the Gplayer 4.0 is only rated for 4/5 hrs and yours is rated for over eight!
After a full recharge, while still plugged in download battery calibration from the market, and follow it's instructions, after you do, while STILL plugged in, reboot. After a full reboot, unplug it, and DO NOT REBOOT until your gplayer completely dies (forces shutdown). Once that occurs, plug it in, let it charge to 100% (while on), leave at 100% for about 15 minutes, unplug, and use as normal. That should fix your issue, unless your battery is dying, which should not occur, even if you are abusing it badly, for awhile longer.

I downloaded the app but its not working i am going to charge my device like the way u said, thank u for ur advises

This is not correct. NO modern device has ANY smarts in the external charger - nearly all current phones (and every smartphone on the market for the past 3-4 years) has a constant voltage 5.0 volt USB input.

First of all thank you for this valuable information, thus I can keep my device on plug while i am driving and using gps otherwise on long distance its annoying to keep checking the battery while driving with gps app on.
Other think is i guess its normal but just to ask, The device becomes really hot on charging while i am gaming. What do u think?
Is there an app that takes time of your battery like today I turned on at lets say 7:00am and the battery dies at 9:00 and you forget the times but the app says how long it lasted. Is there some app like that?

3c's "Battery Monitor Widget Pro" gives all the battery information you could ever need. A data log and graphs allow performance to be analysed over any period of time. You can set markers to indicate charger plugging and unplugging times. Hope this helps.

Off course it will be hot..you play game which hots cpy and gpy and at same time you recharge batery which hots battery..but if battery reach 50 degrese celsius player automaticly stop recharging no matter whow much battery is full.

Gaming = CPU and GPU cranking at full tilt with the display on - of course it's going to get warm.
I was interested in seeing what my charge times were using the official charger and cable so using accubattery i checked the charge logs ranging from 10-40% to 100% and they were longer than what the guidelines stated. Phone did state that supercharging was active, had two thunderbolts on battery as well as the bubble animation (i wish this could stay on permanent )
When i bought the phone, charging from 20% to 100% took 1h 50m
and then in about a months time...
Charging from 10% to 100% took 2h 34m
Charging from 32% to 100% took 2h 11m
These were all with screen off, do not disturb turned on and wifi on. The charging time is not THAT big of a deal as i'm always charging it at night but i'd like to actually recieve the speeds that were promised. Using ampere i never saw the current surpassing 2000mah sub 10% (i don't expect it to supercharge as the battery is nearly getting to 100% in order to prolong the longevity of the battery) and they would fluctuate down to 600-700mah a lot of the time.
So i contacted huawei support and the advisor agreed that the charge times i told him were longer than they should be so i've sent my charger (along with the cable) for repair. It's currently at their repair centre so i've not had a diagnosis yet on what the problem is, it could be the phone having issues for all i know!
I wanted to know if anyone else has been keeping stats on their charge times and whether you are getting times similar to me or slower/faster, would be interested to hear!
Do you have the double lightning symbol? If not, turn off your charger for about a minute and try again?

Cmon man, it's one of first things I mentioned lol...

Difficult to say if there's any hardware issues, the repair centre will find it if there is one though.
Your charging times do seem a little high but its also difficult to compare a new phone to one that's been in use for a while, as there will be more apps running and drawing power etc than on a clean phone. Over 90% charge the charging rate will drop as you said, but that's not the only thing to affect it, temperature has a big impact...hotter charges slower.
Measuring mAh on the phone is therefore only a guide and shouldn't be used to prove slow charging etc. (e.g. if I have my satnav app, bluetooth & mobile data all on, then even using my supercharger, the charging rate shown by the phone sometimes drops to under 400mAh and even into negative figures if the phone is hot)
0% to 100% should be about 90mins in perfect conditions, but I'd be surprised if anyone got regularly near that sort of timing.
Got my charger back 2 days ago and today i deliberatly ran my battery down to 9% to see how charging would go. For the first time since recieving my charger back i've gotten a steady 4000mah. 9% to 72% (+2400mah) took 55m which is much better than the 2hours+ it took last time to get a +2600mah charge before. So yeah, if you're noticing similar speeds, contact huawei and see if you can send it in!
Mine charges from 18% to 100% in just an hour and 10 minutes.
