Slowest Charging Phone I've Ever Used

I just got the HTC One and the phone itself is great. That being said, I have one pretty large complaint...I've never had a phone that charges slower than this in my life. Is anyone else experiencing brutally slow charging speeds? Probably take 5 minutes for it to charge 1% which means it would take over 8 hours to get to 100%. Is this really possible?

Bro, before you make assumptions, give the battery a couple cycles to settle itself.

I understand the battery needs to be trained but I've purchased hundreds of mobile devices in my life. Never has even an initial charge taken anywhere close to this long.

Is this using the supplied charger? Any processes running in the background that could be keeping the phone awake using power?

I know it helped with the old nickel cadmium batteries, but I've been under the impression that conditioning doesn't do anything with today's lithium ion batteries, that they are as good as they will get right out of the box.

Charge time Is a lot less than 8 hours normally. That said, it is still a slow charging phone compared to my previous few phones. However it is not too bad to be a complaint from me. We also have to be aware that the battery is a little bigger than the previous generation of phones, so it would take longer to charge anyway.

Yes this is using the supplied charger. Did a little searching online and it seems that there are others who have this issue. It was noted in the Anantech review as well as the following quote from the Droid Life review:
On a related note, the One takes forever to fully charge. I’m not sure why that is, but no matter what charger I seemed to grab when needing some juice, I found myself checking the status of the battery meter far more often than on other phones in my possession.

My phone needs about 4h to completely charge.

From Anandtech, the rationale is that Qualcomms fast charging is disabled in an effort to preserve the integrity of the battery's longevity; since you know, its sealed and has a repairability rating of 0. The Gs4 will probably crank that fast charge up and the user can replace the batteries as often as he deems necessary.

slow charging time seems a pretty fair trade off for a slow discharging time also right?

Probably this. In the end it is for the users benefit.
I was thinking, even my note 2 don't take more than 3 hours to charge. Heck even my 6200 hyperion battery takes about 5.

You shouldn't fully discharge. And my battery with the HTC charger does not that much longer than other smartphones but agree the S3 is a little quicker to charge.

From the Anandtech review:
What’s interesting however is that the charge curve gets the One to 85–90 percent under the normal 3 or so hours, it’s that last ten percent that takes forever

Maybe they designed it so that the user would be discouraged to fully charge the phone, and thus completing fewer cycles?
If it's just the last ten percent that takes such a long time, I'm not too worried about it. There are few situations during the day that I'd have to charge the phone to 100%, other than an overnight charge.

It's a pretty big batter, to start. But you're probably not getting much current to the phone. If you charge from the USB on a computer, you're hardly getting any current to the phone so it's going to charge very slowly.
The faster chargers are 2A chargers. I have a 2A car charger that came with my Nexus One car dock I've been using for a long time and it's the fastest charger I've seen out of all of them. All of my phones (and friends' phones) have charged must faster with that charger.
I have a 1.5A AC charger too. It's still not as fast as my 2A car charger, but I'm also inside at that point, so it doesn't matter. But most chargers I've seen are 1A or less. Those are slow.

It's not the battery you're conditioning. It's the battery stats on the phone. The phone needs to "get to know" the battery to accurately describe its status.

Charge time should be a tad under 4 hours on AC, so I would say something appears to be wrong. Unless of course you're doing something heavy on battery) gaming/navigation) during charging.

what scm_crash said. pick up a 2A charger if you really need juice fast, otherwise it's probably designed to simply charge overnight for longevity
I always use my nexus 7 charger (2A) when i need juice on the spot.

It's ridiculous that people here think that the HTC one is not reparable ,so HTC designed a phone that can't be open ? What if you break your screen ? So instead of repairing your screen and be charged 180 $€£ for example ,HTC will charge you 599 for a new phone cause the phone is unreparable? That's ridiculous.HTC made the phone,HTC knows how to open the phone ,HTC will put phone back together again period.

It is strange that this forum suddenly has a lot of new negative misinformed posts just when the One is being launched in the USA.
Sent from my Nexus 7 using xda premium

actually it's not comparable coz the volume of the battery aren't the same.
you can also check the charger's specs , a 2300mha battery charged by a 1A charger, that's approximately 2.7 hrs.
still, for the first time it took more than half an hour to charge from 99% to 100% and the LED to turn green, that was strange. probably because I deleted the battery stat file for calibration

Charging overnight?

Would there be a problem with charging the Z2 overnight knowing that is will reach 100% before you wake up, lets say 2-4 hours before you wake up? I have not experienced any over heating with the phone yet but I am worried that it will happen while its charging overnight without me knowing.
I heard that the new batteries stop charging when they reach a 100% is this true?

Yes it will stop charging when it reaches 100%. It's been like that for a while, even my S3 got that.
Leaving it overnight will be no problem (Well should be no problem, I don't have the phone yet)

90 or more % of people do this in that way. There is absolutely no risk. When 100% will be reached, charging will be stopped and phone will use battery power. Eventually after couple hours charger will refill battery ex from 99 to 100%.

Alright that's good to know. my phone is charging right now but its quite cold. Guess the over heating problem was in some devices only.

I thought the overheating problem only occured when recording in 4K. I haven't had any issues with heat except when recording long sessions.
Sent from my D6503

I also did not hear about overheating during charging over the night...

You can leave it on and not worry about heat, but here's the thing: the phone obviously stops charging at 100%, but once it stopped, the phone starts discharging, then it recharges to 100% again, discharges, recharges and this goes on until you pull it off. So while you can safely leave it on cause nothing dangerous will happen to you or the phone, know that it will be in a charging loop which can't be good for the battery.
Ideal thing would be the phone stopping charging altogether at 100%, and not recharging until hitting like 95%. Right now, when it notices the tiniest drop, it will recharge.

^ True. I think it's really NOT good for battery to be charged overnight.

I've done this with all my smartphones. My s3 have charged almost every night for two years. It still lasts a day. I don't think it harms charging it over night.

I can quite believe that that expert knows what he is talking about, however, surely the person that has designed the battery charging circuit will be in the best position to understand the workings of the battery?
Why would they design something that is harmful to the battery in normal use?

As an electrical engineer I'd like to point out that having the battery charged is the best you can do if you're using an lithium-ion battery. I read a lot of nonsense in the Internet regarding this matter. Only if you'd like to keep the battery unused for a long time it's good practice to keep it at ~50% (that's why the manufacturers do not charge the battery to 100% when it comes out of the factory).
But you don't have to believe me, it's your battery. Who cares?

That's a myth. The cost is mariginal if you take into account how much energy the whole manufacturing process does consume.

How and when do you charge your battery?

Do you let your battery drop down to 5% before connecting the charger? Or do you charge every moment you get the chance to keep battery at max?

Battery łasts a long time as it usually goes off the charger at 7 a.m. I charge it while sleeping. Occasionally out of habit I will charge it while I'm driving in the car but for about 15 minutes. Otherwise, I am very happy with the battery.

I'm not an expert, but all I've heard is charging over night or after it hits 100% is bad. Why I don't know, but I try to charge my phone when it reaches everywhere from 15-30 to 95-100 then remove the charger.

I'm not constantly on my phone, so usually charge it up to 80% and recharge when it drops to 40%. I only charge it to 100% when I am out and about for the whole day. See the following link for charging advice:

Nah, that's old news. Modern chargers and devices know when they've hit 100%, so they stop charging at that point and lets the battery dip down to 98-99% before trickle charging up to 100 again, and so on until you unplug. It's completely safe, and you shouldn't trust all those garbage click-bait articles out there. Do not, however, go down to 0% before you recharge it. That can actually damage the cells in your battery, so plug it into the charger before that. If you notice some funky behavior from the battery, like if it's jumping from 30% to 20% in five minutes, or is stuck at 10% for an hour, then it's a good idea to completely drain it to 0% to calibrate the battery since the OS has no idea how much battery is left (so it knows where 0 is again). This will usually happen after flashing a different ROM. Charge it up to 100 again and it should be back to normal.
I personally charge it normally at night, without quick charge, since there's no point in having it quick charge while I'm a sleep for around 8 hours. I'll only quick charge it in the middle of the day, which is almost never, since the battery is freakin' awesome.
Don't worry about the battery too much, but don't reach 0% too often, and you'll be good. By too often, I mean every 3-4 months or so is OK. I base these things from my Sony device which I've had for almost 3 years. The (sealed in) battery was very good out-of-the-box, and it's still very good after nearly three years, so I won't mess with a proven success.

To be safe on the longevity of the battery I use one of these with my wireless charger :
http://www.amazon.com/gp/aw/d/B003P...mer+outlet&dpPl=1&dpID=31OAEbif0lL&ref=plSrch
My battery is usually around 30-40% at the end of the day. I use the regular speed Samsung Charging Pad and set the timer on this outlet for 3 hours when I go to bed. So after 3 hours it stops charging and I don't have to worry about the possibility of damaging the battery (I know about trickle charging, but I think this is better)

Ive read somewhere that the new s7 edge charger doesnt have a power inverter so it keeps charging and wasting power which could damage the charger or possibly device. So know if thats correct.

I just purchased one of those...thanks for the advice. I charge my device when get around 20%-30% of battery and left charging over night ( when sleeping) on my standard Samsung wireless charging. My battery is just ok.. I'm not so heavy user and sometimes I have to charge around 8pm or so. I take off from the charger at 100% all morning around 8am.

At home. I do wireless when ever i can. If im not using the phone then i sit it on a wireless charger.
Battery hasnt drop pass 30% in the week i had the phone.
My note edge would drop pretty low because i didnt use wireless charging. So my phone would just sit in my pocket slowly draining.

Whatever you read, either you misunderstood, or the person that typed it was a bumbling idiot. A power inverter converts DC power to AC. Your source/utility power is already AC. A USB charger is merely an AC adapter made for USB. The phone has integrated circuitry that controls when and when not to charge the battery and at what amperage.

I usually let mine get to around 5% everytime. Then charge it back fully to 100%.

Not at all, but just try to not discharge the battery completely to the point where it turns itself off. It won't ruin the battery to the point where you actually notice it there, but it's better if you just turn the phone off if you're able to (unless it's an emergency, of course).

Sended from my Samsung Galaxy S7 Edge Gold Platinum

I charge it when it hits 20%. But i dont use the fast charging unless i need a quick top up

Does it hurt the battery to charge the phone with a different charger ?
Sent from my SM-G935F using Tapatalk

I never used the fast charging, I think that slowly charging a battery is better for the lifetime. Most of the time it is below 10 % before I plug it in and I also want it to be at 100% and ready (green LED) when I unplug it.
my note 3 battery is still superb and I got the phone since 2013

Best way to keep a battery in good health is to charge it to full before you start using it. Also, try and never charge it until it's less than 50%. Charging it overnight is perfectly fine it won't hurt anything but once ina while, at least say once a month let the battery drain all the way, try to turn it back on if it goes off sometimes there is still some juice left and it might start up, once it won't start anymore try and charge it without turning it on to full. I wouldn't do it more than say a couple times a month any more than that is overkill and may do more harm than good. These are the guidelines I use and I have never had battery issues. I currently am waiting for my S7 Edge and on my Nexus 6 I usually get 48+ hours with 4+ hours SoT. I'm just an average user currently.

A (new) way to increase battery life on the S7/Edge

Hello,
I am doing an experiment since few days ago. I noticed that if you disable the Fast Charging, and (most importantly) use a proper, thick 2A USB cable (I use a Kindle Fire original cable) then the battery lasts around 15-20% longer.
How to recognize that you got a proper USB charging cable ? With fast charging disabled and the battery empty, the phone should tell you that there are around 2 hours until full (instead of the usual 7 hours or so with fast charging disabled). That's when you know that you are using the proper cable. I bought a original Kindle Fire cable from Amazon and that is very solid, much thicker than the standard cable. See attached screenshot. With the standard cable this seems to be a hit and miss, you sometimes get the 2 hours message and sometimes the 7 hours message.
I repeated the experiment 3 times and each time I got significantly better battery life than before.
You may want to try it to see if it works for you.
PS: Attached is my latest battery life screenshot (APC8 firmware), which is the third charge since the experiment. 2 days 6 hours of stand-by with 5h SOT on a mix of 80% Wi-Fi, 20% 4G with nothing disabled (even Bluetooth is permanently connected to the LG smartwatch). Almost no videos played, only web page browsing which is quite demanding on battery.

Look if new software update is possible.

Yeah, I noticed that my battery life was worse when I used a ****ty 1 Ah Sony charger when I displaced the original Samsung charger. It took about 3 hours to charge it up to 100%, but then I noticed that the battery life would be worse than before. I found the original charger again, and battery life is back to being good again. I never use fast charging, unless it's in the middle of the day and I'm heading out or something.
None of the things mentioned above should (technically) have any impact on battery life once unplugged? I mean, stored electricity is stored electricity, so if someone QUALIFIED could give an explanation here, it would be cool.

Nothing new, I've always noticed that if I charge the phone with the original charger and fast charging disabled it will last much longer.

This cable? Which AC adapter do you use?

None of this solutions should impact battery life Oo. Energy is energy, no matter where it comes from?!
Would be nice, if someone qualified could tell us more..
Do you have the newest android version installed?
By the way, I only charge with original charger and cable, fast charge disabled (battery life is longer?!)

Battery life depends on how well you follow charging & discharging cycle. I usually fully discharge my battery (so that phone will shut down by itself after dropping below 1% charging), then charge it fully keeping it switched off & then use it.
I always had far better battery life than most people complain about.
BTW, I also tried charging battery keeping phone switched on at 10-15% charge remaining, battery definitely performed weaker for my use.
So that confirmed my theory based on my usage over last 7 years..

Yes, this is the exact cable I am using. A bit expensive, but for me it was the only cable that consistently worked at 2A over time.

I wonder if Qnovo is qualified enough ? Their technology is employed in many charging solutions. Here is what they say:
"Add fast charging - it gets noticeably worse. It turns out that the simple way batteries are charged today causes most of the damage that leads to shorter daily battery life and reduced lifespan."

So you're saying that Kindle Fire cable extends battery life? Isn't 100% battery life from one cable the same as 100% battery life from another cable? Energy is energy.

In no way I am saying this. I am just saying that you need a cable that reliably supports 2A charging, so the charger shows 2 hours to full instead of 7 hours to full, even with fast charging off.

Ah okay. I went ahead and bought one!

It ' also the logical thing. With fast charging , the battery holds less charge than the "normal . " He just spoke in various forums of this.
Anyway , great idea.

How to maintain max battery life span (reliable source):
Perform shallow discharges. Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
·Don't leave it fully charged. Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. When possible, keep it in that range to prolong its life as long as you can. And, if you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health. If you need to charge it overnight, use something like the Belkin Conserve Socket to stop it from charging after it's full.
·Fully discharge it once a month. This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries", which means that they can tell you how long you have until your battery dies (e.g. "2 hours, 15 minutes remaining"). This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.

But you stated that it increases battery life.

So you're saying that Kindle Fire cable extends battery life? Isn't 100% battery life from one cable the same as 100% battery life from another cable? Energy is energy.

What he's saying is that a slower charge equals a longer lasting battery between charges.
But maybe that doesn't apply to Li-ion batteries, according to this link here.

You can try it for yourself (if you have an S7/Edge) and report the results here. I posted my results, I'm not an expert, I just tried this. I also tried the 7-hour slow charge (with a different charger) and it didn't work as well as the 2-hour charge. The 2 hour charge seems to work best.

Yeah, If you use fast charging the battery dies a little bit quicker. I recommend fast charging if you are in hurry.

I only use fast charge when I'm in hurry.. Nice feature! I try to charge my phone between 25-80%...

Battery life depends on how well you follow charging & discharging cycle. I usually fully discharge my battery (so that phone will shut down by itself after dropping below 1% charging), then charge it fully keeping it switched off & then use it..

Worst thing you can do for the lifespan of an Li battery.

I disagree, even though it switches off itself, it still has charge, don't go by it says 1%.. so it's not fully discharged... besides my method served a good battery life to me over the years with earlier phone models

Please Help moto x play huge battery issue

I used samsung fast charger for 4 months and battery life was all good , then i lost the charger so i had to charge the phone with a "not so fast charger" that took ages to charge my phone.
Never charged to 80% , and battery drain was serious.
That's when i got worried that the charger ive been using might have destroyed my battery.
So bought the "turbopower 15" charger for my MXP and at first it heated up my battery more then 60* (serious overheating issue)
After 2 or 3 charges i figured it only heats up after the percentage is 50% or higher or when i use it while charging.
And now it drain my battery like crazy!,
I just restarted my device into recovery right now and it was 45% but by the time i booted up to recovery it said 25%. How CRAZY DRAINAGE IS THAT??, Please devs help me.
Its like i dont need a stopwatch my battery drain a percent per second.
Im using purenexus 7.1.2 by @GtrCraft witb stock kernal

try going back to stock rom, if the problem persists that means the battery is bad

I was just using stock rom but the battery drain was still the same. I dunno if ive messed up the battery because of the "not orignal" chargers or whatever the reason is. I think the battery is now done for. I think Im just gonna sell this phone

Just buy a new battery from ebay, replace it urself. It's easy..

Thanks god. my battery is back to normal after charging it a couple times with the turbopower 15 charger. now when im home i never let it discharge past 70% this way it stays in good health.
when it went bad it discharged 10% in 20 minutes now its 10% in an hour

I use tronsmart 3.0 turbo charger (backward capability for quick charge 2.0 devices). Battery life is good. I charge it when it hits 15-30%.
