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.

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.

Hey Everyone,
I apologize if this is a repost. I know I read somewhere (I believe here) about a similar issue, but I couldn't find it in searching.
A little background - AT&T SGS2 running stock rom (2.3.4), rooted, using a custom kernel (2.6.35.6) I got off of here.
Anyway, my phone has been working great for months. All of a sudden, my battery indicator is completely wacky and innacurate. It seems to have started after I came back from a trip and had to put it in 'airplane mode' a few times.
The battery level indicator goes down very quickly, and is not a true indication of my phone's charge level. I noticed it a couple days ago (after we came back) where after about 6 hours, I was down to 40%. Normally after a full day's usage I am still at ~80% by the time I get home from work. Since my phone had been running for weeks without a reboot, I decided to reboot it, thinking maybe I had some overzealous background processes running. It came back online with the battery indicator at 8% (down from 40% a minute prior)! After about 30mins or so, it began to go up, and settled around 14%. It stayed at this level for hours, until I plugged it in when I went to bed.
The next morning, same thing, it would lose 1-2% every few minutes until it got down to <10%, where I would get a warning about a low battery level. But once it hit that mark, it would stay there for hours and my phone would work perfectly fine.
As I mentioend above, I thought I read a similar story where the recommendation was to turn the phone off, charge it up all the way, and then turn it back on after it was fully charged. I tried that last night, but my phone is down to 87% after only 2 hours of non-use.
I've made sure that UV/OC'ing was disabled, that no background apps are doing anything weird, etc. And it's not like my battery is really dying quickly - it's just that Android thinks it is. I've checked the level using multiple programs, and all report the same incorrect information.
Does anyone have any suggestions on how to fix it? Thanks!
You have encountered two separate issues, one of which is widely documented (fuel gauge reaction to rebooting), one of which is unexpected but possible on UCKH7 (abnormal drain).
But it doesn't look like the battery is really draining that much quicker, only that it's showing that it is. For example, while it might take me only 3 hours to go from 100%-10%, I'll stay at 10% for hours.
It's like the battery is no longer calibrated properly.
Do you use Samsung original charger? If not, try. It should go away.
Take your battery out for a few minutes. The SG2 differs in that it uses a chip for battery calibration/stats. You need to cut power to it completely to reset it. Now, if it still does it afterward, either the battery is faulty, or the phone's ability to measure voltages is wonky.
Also, are you using the phone's Power Saving mode? Maybe the battery is dying but the phone is taking steps to make it last longer?

I used to never use my Samsung charger and never had issues. However, months of using my blackberry charger has rendered it now ineffective. The charger dongle was slightly smaller, and its continuous wiggling messed up my phone's power port slightly. It's a good thing that my Samsung charger still works.
When we were on vacation, I was using my wife's charger for her phone (T-Mobile G2x) so we didn't need to take two (seemingly) identical chargers with us. My understanding was that the pinout and voltage were all the same, so I didn't think it would matter. Maybe that had an impact?
Normally I use my Samsung charger, and have been since we got back.
I haven't tried removing the battery yet, since its in a hard shell case and was hoping I could resolve the issue without taking it apart. But I'll try that tonight.
Power saving mode is disabled. I've also disabled BT, Wi-Fi, GPS, and shut down every app. In the time since my first post (84%) and now, I'm down to 58%, and my phone has been sitting on my desk unused the entire time.
According to the built in battery monitor, Android OS accounts for 92% of battery usage, with Display at 3%, Cell Standby at 3% and Phone Idle at 2%.
As I mentioned above, I thought I read something about a 'trick' to reset the battery gauge by turning the phone off, charging it to 100%, unplugging it, and then turning it back on. Was I mistaken?
Thanks for the responses.
FYI - I just pulled the battery, let it sit for a minute, and plugged it back in.
Battery level went from 58% to 39% after it powered back on.
I'll try charging it again to see if it has any noticeable impact.
Oh, I did want to mention that I've been very religious when it comes to charging my phone properly and trying to "take care" of the battery. I never let it get below 20% (outside of recently due to the issue), I always charge it up to 100%, I never do quick "let me just charge it for 15 minutes to make a call" type charges, I always use a wall charger and not a car charger, etc.
Down to 38% during the time it took me to type this...

That to me sounds like you might have an app creating a wakelock and preventing it from going into deep sleep.

With the exception of high load immediately following a reset (which is why it goes funky on a low-battery reboot), it's basically impossible for the fuel gauge to go out of calibration. It's designed to continuously converge towards truth.
Check the raw battery voltage when it seems to be funny. If your voltage is consistently low, you might be experiencing a hardware failure (like maybe the battery's protection circuit is on its way out.)
After pulling the battery, putting it back in and recharging it, it seems to be working well now. Too early to say for sure, but I went the entire afternoon and evening (up until now) with some mild usage, and am only at 84%. So far so good!

The phone has a voltage drop which causes the drop from 58 to 39 when you reboot it. I'm not a fan of it either.
Hello everyone. First off, I have read this - Things You Should Know About Lithium Ion Battery. Secondly, I know this smartphone has a weaker battery than most, which combined with a dual-core 1ghz CPU makes it drain in about two days on average (I am an entry-level user). However, I've managed to optimize battery life through various options and by staying on factory Android (2.3.7) so now it can last to about four days, so I was very happy. Now more about the 'incident'.
Usually I charge my phone at home on an unused wall socket. But this time I charged it at my friends place on an extension cable which was literally packed with cables and his PC stuff. First thing I noticed is that it took a lot longer to charge my phone. It took nearly two hours to charge my phone from around half capacity to full, while at home this is usually accomplished in 30 minutes.
After this I've noticed that battery life deteriorates much quicker, it now lasts about a day and that's when just idling and not doing anything (!), so I'm back to the state before I managed to prolong battery life and even worse.
So what happened? Did my phone suffer irreversible damage to the battery?
As much as I can tell from a layman point of view, the AC flow on that extension cable felt 'unstable' so maybe it means the battery was charged with 'lower quality' current?
Now every subsequent charge I do at my home improves battery life for the first few hours, but after a point it still deteriorates rapidly and that's while my phone is not even awake. I get the feeling I should let it discharge completely (even though this is not advisable for Li-Ion) and charge it fully from zero to full capacity? Kind of letting the battery format again in normal conditions maybe?
Much appreciated. Luka from Serbia.
Here are the screenshots (cant post full links)
imageshack.us/f/706/wt9e.png
This is how my battery life looks after 22 hours. As you see, most of it was when the phone was not awake.

Even using 2.3.7 that's not normal... your problem it's not from that "episode". It's from the past
Hi
I use my V30 as Hotspot the whole day and this sucks battery quite quick. Is it problematic if I keep the power cord (usb-power-plug) connected all day long? Does the phone still use the battery in that case or does it just draw its power from the power cord and only recharge the battery if it drops volatge by self discharge...

I'm not sure I believe that site... I have been a fan of Battery University, but in my experience they got this wrong. My Droid Turbo battery lasted for 4 years before I switched to the V30. I always charged it and left it charging overnight. My laptop that I'm typing this on now, has the original battery from 8 years ago, and it's still working. This laptop stays plugged in almost all the time. Certainly, it doesn't have the life that it would if it was new, but it's been 8 YEARS.
In my case, I keep my devices pretty long, and it doesn't cause a problem. So, I won't bother to unplug at night... it's not worth the hassle. Most people would upgrade their hardware well before these times, so they would notice the problem even less than I do.
The bigger issue I see is when it the phone overheats. My work phone (in my crappy work car) sits on a mount on the vent, which (because of the crappy car) doesn't close completely. So, this winter, it got very hot relatively often. That has hurt the battery life on that phone (a Turbo2)... which now has much less life than my Turbo does. But, it's a company phone, so they're going to replace it... not my problem
The other issue I see is charge cycles. My wife's laptop was often charged, then run on battery, then charged, etc. The battery on that laptop was only about 3 years old when it stopped performing (wouldn't even run the laptop for more than 10 minutes). IMO, charge cycles are, therefore, more important as than overnight charging.
Just my $0.02... feel free to disagree if you want.
Exactly! Charge cycles!
I only charge my V30 every 2nd or 3rd night for that reason, and I still get 7-10 hours SOT after 1.5 years, depending on how much music I play in addition to the SOT.
That said, it's also best to avoid draining the battery too low. The chemistry suffers the most when it's very low or very high.
Keep in mind, with charge cycles, they say it's proportional as well. So, if you charge 25% for 3 days in a row, it's the same as charging 75% every third day. I prefer to keep the phone charged as much as possible, in general.
Also, I neglected to mention, my overnight charger is a slow one (not a QC one). That way, it's slow charging overnight anyway. This speaks to the heat cycling of the battery - QC does heat it up more than a slow charger would. That's also why I don't wireless-charge, as it adds to the heat, too (at least it did on my older phones)...
I keep reading that you should try and just charge your phone to 80% to help keep the battery healthy, as going to 100% can shotren the life span of the battery.
How ciritcal is this?
I know letting your phone run down to 0% is bad as it takes a fully clylce then to get back too 100% and this is not good for the battery long ter, but i must confess i usually let my battery get to around 50/60% ish then charge back up to 100%
I've always charged my phones fully and never noticed any issues. Maybe if you plan on keeping a device for 10 years, but for the usual lifetime of a phone it's just fine. My OP7 is 2 and a half years old now and still has 86% battery health. I've seen others in Telegram groups say that they never charge to 100% and when they post their battery health it's not much different from mine, sometimes even less.
I think modern batteries are fine being fully charged ... otherwise the OEMs or battery manufacturers would limit them to 80 or 90% by default.

Hehe yea, I guess they all show 102% then because I have that as well
I like the adaptive charging, set up your bedtime and alarm for getting up (or turning over) After bedtime, phone gets trickle charged to achieve 100% at morning alarm. No excess heat etc. Phone then lasts me all day till bedtime when put on airplane mode, switch off Wi-Fi, & sleep. Works for me.
I'm showing 106%
I always charge to full, using adapting charging over night. Charging slowly and keeping temperature down is more important than keeping it to 80% from my understanding.
I just lay my phone on a slow charge Qi pad every night and when I get up it is at 100%. Nexus 6, Pixel 3, now Pixel 6. Perhaps my battery life went down a bit on my Pixel 3 after 3 years, but not enough to notice. I think 100% charge (at least slow charging) is safe for 3 to 5 years of battery life.
Li's like frequent midrange power cycling; it can extend the lifespan hundreds even thousands more full charge cycles.
Voltage and temperature are the Li's biggest stress factors. Low or high temperature charging can cause Li plating.
The higher the cell voltage, the faster it degrades.
The same is true with temperature.
Personally I just replace them every year or so as a failed Li can severely damage a phone. They tend to swell during a failure which can easily damage the display.
My Samsung S10+ is 27 months old now. I'm charging it to 80% mainly daily. Had maybe max 20 full charges and only once or twice to zero. I'm at 86% battery health (according to 146 sessions). Was 92% six months after buying brand new.
I think it helps. Also since the battery is OK (4100mah), dont need that extra 20%.
EDIT: 15W Samsung "fast" charging. As fast as that is ...

A Li is considered degraded when it reaches 80% of it's initial capacity. This signals the end of its useful service life.
Degraded Li's are more likely to fail.
Trust me it's better to replace it before it fails...
I think Better Battery Stats made that reco back in the day.
Charge to 80% and plug in at 10%.
Not so sure that really matters anymore though.
Both my 2 XL and Pixel 5 were plugged in before bed, unplugged when I got up, plugged back in when I hit 10-15% or when I went to bed.
If you plan on keeping your device for a long time (like 3-4 years) doing the unplug at 80% and plug in at 10% might make a diff.

10% is too low. It causes a lot of stress on the battery as it drops below 20% to charge from that starting point or lower.
Worse there's little usable energy after 20% because of the lower voltage. The phone uses the same wattage which is determined by V×A=W, so as the voltage drops it needs more milliamperes to make the same wattage. The discharge rate increases as the cell voltage drops.
A better low cut off is 30-40% or even higher and a high cutoff of 80% although 62% is optimum.
The Li likes frequent midrange power cycling. Charging beyond those parameters is for your convenience at the cost of battery lifespan.
Batteries are cheap and most are easy to replace... so I don't sweat it.
I expect a service life of 1-2 years on a heavily used N10+ battery.
However charging in the 40-72% range yields the most rapid fast charge in the shortest time so it makes sense to use this whenever convenient.
Well, I know things have been updated within Googles code itself.
"Adaptive Charging" / "Adatptive Connectivity" additions.
This was a real big problem for me with my HTC 10, (2016)
Battery degradation threads starting popping up.
I installed Accubattery after 1.5/2 years of owning the device and the battery was degraded to about 77% capacity at that time, IIRC. I was charging to 100% at that time, also.
So, I began charging stricly to 80%.
Compared to my HTC One M8 that to this day still has 90% capacity, and I used that device from the day Verizon released (3/2014) it until the day Verizon released the HTC 10 (5/2016).
I somehow managed to use the HTC 10 up until I bought the Pixel 5 on release day (10/2020).
I was charging the HTC 10 like 3 times a day just get through, and even went back to the HTC One M8 at one point because I had enough, but was waiting for the P5 to drop.
So to answer the question, I do believe it helps.
I do think that Adaptive charging/connectivity help, as well.
I take the view that if I don't need all the capacity on a particular day I charge no higher than 70%, which lands me around 30% end of day. Otherwise I'll guestimate what I need. Off to take some photo's tonight, so will probably charge it to 90% or so.
If you like fiddling around you can use something like Tasker to switch a smart plug that your charger's plugged into on and off at what you consider appropriate battery levels. Makes it all painless once set up. Or you can buy some extra hardware too. I use this in my car to limit the phone's max charge and temperature as, for me, I think most and fastest damage is done in a hot car float charging the phone at 100%.... https://chargie.org/ Not cheap but ok in my mind to hopefully extend the service life of the phone's battery. Less than the cost and hassle of replacing a battery anyway! (I'm not associated with Chargie other than as a customer)
OK, admittedly off-topic, but, this kind of sounds like a variation of the guidance I use for charging my electric car. Don't charge it unless it drops below 80% (so don't keep topping it up), but don't let it go below 20% regularly either. I mostly plug it in at around 60% and let it fully charge. Given the cost of a replacement battery would be more than the total value of the car, I hope this gives me 10 year of life.

EV metering is set up differently. What shows as 100% is likely a conservative 80% charge. Research for that variant.
A 35-40% low cut off is probably better as going lower generates more heat causing needless stress... unless you need that capacity.
Just downloaded the accubattery app and then fully charged but it’s estimating 6,401mah. Must be wrong and needs to calibrate over a few days.
I’ve never had any problems charging to 100% before so I’m not stopping now. I’ll be deleting this app if it keeps warning me like it has done.

Turn it off then.

Accubattery just provides a guide. See here:
battery drain
Hello, I'm using a pixel 6 with two cards sim. When I go to sleep the phone is fully charged and internet/wifi is turned off. When i wake up i have 88% battery (I lose 1,5% per hour). In battery use i see Ims Service. I did a test and in...

I used to cycle from full to empty on my Pixel 2 before recharging, at about 3 years the battery couldnt last until lunch anymore. This meant more cycling, and I could fully discharge/recharge it 3 or 4 times a day. Within 6 months the battery only lasted 5 minutes, it was stuffed. Phone always hot and needed to stay on a charger 24/7, would turn off if I opened the camera without usb power connected.
Held out about 6 months on a permanent usb battery bank, was such a slog to wait until the Pixel 6 was released.
