Fast charging stops at 71% - Android Q&A, Help & Troubleshooting

Hello guys I´ve been having a problem a little bit after i bought the Zenfone 2. Whenever i charge the phone it always stops at 71% and goes to normal charging and takes longer to finish the charge. It has the last version 2.20.40.156. Can someone help me with this?

That's how fast charging works - it charges fast up to 70% then charges normally. If it did high-power charging longer then it would kill the battery.

You should read about how quickcharge (same thing as fast charge) works.

that's how fast charging works man. No problems

"As far as how it works, quick charging allows you to dump a lot of power into your battery by using higher-than-normal voltage until it reaches what's called "saturation" - usually around 60-80% charge depending on how the phone's power management is configured. At that point, the phone's power controller scales back the amount of power it's receiving and your phone will begin to charge more and more slowly as it approaches 100%. This is where the "adaptive" language comes from in Samsung's fast charge marketing - quick charging allows your phone to intelligently scale the amount of power it takes from the charger based on the current charge state of the battery."
And the reason behind slowing down the charging as it comes to 100% is to minimize the wear and tear on the battery, so it lasts longer.

my zenfone always charges from 1 to 100% with fast charge with the + sign does not stop or anything. profile set to power saving or performance does not effect anything. i bought my phone amazon 6 months ago

Thanks

HTC Amaze 4G Taking 4+ hours to Charge

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.

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.

[P760] How I (accidentally) improved battery life

Hi, I would like to share my experience on my L9 P760 (v10a unbranded form TIM Italy with root) about the following issues using the original LG charger:
1) I never power off my L9 and usually I recharged it in the night (not in airplane mode) while I am sleeping, so I plug the charger at 23:00 and I detach it at 7.00 with a charge variable from 94/95% to 100%.
2) The first hour after dectached from the charger, the phone drain battery very fast, tipically 7/8-10% in about 1 hour (also by doing absolutely nothing on phone), next it gets a quite normal battery consumption.
Assuming these 2 conditions, I always have used the phone in the same way and basically with the same set of apps used and installed. I leave all sensors always on, the 3g, the wifi, the bluetooth connection always on with a full synchronization for two google accounts. The main activities I usually perform on the phone are check the mail with GMail, read a lot of news with Currents, a moderate usage of Facebook and Twitter and watching some video on YouTube. In these typical scenario usage, the maximum performance I obtained from battery was about 28 hours with about 3 hours of active screen usage. Quite good but...
Accidentally, I discovered that charging the phone with another charger (not LG, in my case an Asus charger for the tablet TF101G but I think it could work by using any charger with a different volatage output respect to original) give me an incredible improvement on battery life. Not only when now I detach the phone is ALWAYS at 100% but also the fast battery drain observed in the first hour is gone. Now with the same usage scenario described above yesterday I have obtained 44 hours of usage (with a residual charge of 14%) and more than 4 hours anf half of active screen usage. I am quite sure that this behaviour depends on the charger because I repeated the entire cicle of charge-use_the_phone-charge for three times and I always obtained these consistent results. Next I tried to charge again the phone with original LG charger and I have again the same set of issues reported above.
I attach the screenshot of battery usage this morning just to show you what I said.
Anyone has found a similar behaviour on his L9?
hm more should try and post feedback, i dont have a second charger and i also notice the same battery drainage with loosing fast the first 7-10% after charging and phone not full when i wake up in the morning.
Is there possible a battery damage by using an other charger? this seems like a charger thing, lg to low the costs of production in this model has cutted down the quality in every peripheral of the phone, charger cable headphones etc

For what I know (please someone correct me if I am wrong) it should not be a problem. I think you can use without problems any charger which have a maximum output greater than the required input power of the phone (the power in excess will not not be used).

lolz, :laugh: replace your original LG Charger, must be faulty. You just said its unbranded TIM Italy.
I get similar good result with original charger. My battery lasts more than 35 hours with business use and more than 40 hours after moderate use. Or may be P765 in India got good quality chargers than other countries.
REASON FOR SLOW CHARGING: LG EXPLAINS IN WHICH CONDITIONS L9 CHARGES TOO SLOW HERE ON THIS PAGE . In your case your Networks (3G, BT, etc) are always on, that means CPU is always working at some extent and L9's built-in feature slows your charging to avoid OVERHEAT problem explained on this page. LG have restricted heavy CPU usage and Charging at the same time to avoid device malfunction.
EDIT: Any technical person will tell you overnight charging is bad for battery and phone as it creates too much heat and that damages battery. And yes, My phone gets 100% in around 1-3 hours. And when you say you need to charge overnight and its still 94% sometimes, then dude you have slow charging problem with your charger.
cmahendra, first of all, I want to thank you for the precious tips and solutions you give us in the forum. :good:
Let me clarify some points:
My phone was originally a branded TIM next I unbranded it and transformed into a kind of european V10A (I said "kind of" because I flashed european firmware but the software version shows p76010a-222-01 differently from a real european phone. It seems that this code is computed by using also the IMEI.)

This explanation given here can not apply to my situation. In the night the phone basically is always in deep sleep, so there should not been overheating problem, so the charger should work at its full power.
I even don't think that my charger is faulty because: 1) this problem (of not completely charge the phone after a night) is common to a lot of other L9 P760 users (as reported in other italian forums and applied even to branded or unbranded europoean firmware). 2) I can confirm you that if I charge the phone during the day it reaches the 100% of charge in about 2, 2-5 hours but when I unplug it it has always a very fast battery drain in the 1st hour. Some days ago, with original LG charger, I discovered that in the night, ithe battery has a continuos fluctuation from 100% to 95/94% as showed here:
so this is probably is the main reason why in the morning when you unplug the phone you obtain a variable charge of the battery.
I think it is a strange behaviour which is related to some bugs in LG firmware on P760, at least in v10a. I even don't know if this problem has been fixed in the last v10h (and possibly someone can confirm us). Anyway, for now, I will be remain to v10a just because I need root for some applications.

Input:100-240V ~0.5A
Output:5Vdc/2A or 15Vdc/1.2A
about the chargers... you can use any charger that has 5.5 DCV output. The trick for the slow charging is the current, I charge my L3 with original lg charger with 0.7A (700mA) and it charges from 0 to 100 in 3 hours max, so try another charger that has more output current

I read on several other forums that should not be a problem. Example:
http://forums.androidcentral.com/ve...se-tablets-2a-usb-charger-charge-rezound.html
Anyway, next days I want to try with another less powerful charger. I have also noted that the phone while charging is not overheating, so it could be a good signal that all is ok.
Tonight, I also want to use "Battery Monitor Widget" to get useful statistics about temperature and power absorption while charging the phone.
I will let you know something soon.
I've got the same problem. I charge full my L9 and when I detach my mobile from the charger the battery starts to drain fast even if I don't use it or unblock the device. Then, when the battery reachs about 80% of battery, the consumption stabilizes quickly. In general the battery life is quite good but I expected more of a large duration battery.
The strange thing is that when the baterry is low, (more or less at 25%) it drains so much slower compared to when I unplug the charger. Any more suggestion? I've bought it 5 days ago and I've charged it 3 times.
Thanks for your help and sorry with my english, I'm spanish
It was once posted on xda portal that charging from a pc (usb port) although it's slow, it makes the battery last longer, because of low voltage, so using a charger that passes less voltage is always better, but the charging process is longer.

Cool. The thing is I turn my PC off at night so I use the travel adapter included with the phone. I have noticed my battery always starts at 99% instead of 100% and seems to drain fast to 95%, but afterward the battery life is good.
I turn off my wireless most of the time because I saw wlan_rx_wake was causing an unholy amount of wakelocks due to some dynamic IP crap. I also turn on airplane mode at night because I want to sleep. I also ran the T-Mobile bloatware disabling script by LG here. I have no idea how much of a difference that made. However, I left location services and sync on because I noticed very little difference. I play about 15 minutes of games and use the screen for about another 105 minutes everyday. My battery drains about 40% in 30 hours. So I can get two or three days of charge before I have to recharge.
Here's my current power breakdown after 32 hours, according to GSam Battery Monitor:
Screen - 64.1% (Medium brightness, 50%)
App Usage - 25.0% (Android System - 5.5%, Kernel [Android OS] 4%, Game 1 - 2.5%, Kii Keyboard - 2.5%, Game 2 - 2.4%, Live Wallpaper 1.0%)
Phone Radio - 10.1%
So I have some news...
Relative to temperature while using the tablet charger, I can confirm that the temperature reached by the phone while charging is not high , like when you use the phone for normal activities (about 24-25 °C). See yourself the attached image.
I have also try to use another charger (in this case a Sony charger of the Xperia of my wife) which incidentally has the same specs of the original Lg charger: output:5Vdc/0.85A. I expected the same behaviour as with original charger (so with the same issues) but I obtained a correct charge at the end (100%) and no continuos fluctuation from 100% to 95/94% as reported with original charger (check the attached image).
So my conclusion is that there is something that does not work in the original charger. The strange thing is that a lot of us have these problems so I don't' know if this a build problem of the charger or a set of flawed transformers...

I don't know the specs of the charger of Toshiba but you can use any charger which has an output of 5Vdc. The amperage of original L9 charger is 0.85A so if you use a charger with more amperage, you will charge your phone faster with higher temperature for battery, with less amperage the phone will charge slower but with a lower temperature for battery (in general the high temperature is a known enemy of the health of a battery). My tip is that you should use a charger with the specs similar to the original LG charger.
I tried using the USB charger on my laptop instead and I did notice my first 5% of battery drains much slower than before.
The L9 has a good standby life. By running the LG bloatware disable script and disabling specific apps myself, I was able to draw less than 1% on standby with 15 minutes of active screen usage and wireless turned off. With airplane mode turned on at night, the phone can last even longer.
However, the battery drains very fast with active screen use and wireless turned on.
Can you all please post what is your battery's voltage when it is at full charge BEFORE you unplug the charger??

Faulty behavior in battery drain

Hey guys what's this means?!
My battery is falling down automatically with no use!
See
I am wondering about this faulty behavior because i am in 510 firmware with no extra apps installed
I had this issue with. 475 too.
Help me please if this is a hardware issue send it back for second time in this week!
Instead of i charged this phone two time totally when i am bought it.first time faulty drainage happened yesterday when i played some game and battery went to 80% then i went to sleep for half an hour and when i turn the phone on again,noticed to battery is lost to 30%!

It happened 2 or 3 times, when I plugged the USB cable to the phone (other end connected to a PC or charger) and the phone LED immediately turned green and the battery indicator jumped from 60% to 100%.
Nothing happens if I re-plug the charging cable, the phone keeps saying it's fully charged. Even powering off doesn't help.
The 100% power won't drain faster but I noticed that when it goes to 30% the phone will shutdown because no more juice is inside the battery and the indicator will go back to less than 10% after re-plugging the power cord.

In your case i think that's better try it with latest firmware.maybe solved.
But for me,the story is different,unfortunately!
another Q has been busy in my mind. Why sony didn't used a better charger for this phone?! Charger has only 1.5 mA output power! For test, i am charging the phone now with s IV charger (2mA)

Higher mA output is not necessarily better.
Taking more time to charge is more gentler on your battery.
Pumping up the mAh to 2 or higher will improve the charging time, but the number of total cycle charges (i.e. life span of your battery) will go down and suffer.
Anyway, 3 hrs from empty to full is normal, right? Anything quicker is a quickcharger.

Ok.no problem dude.3 hours is good time charge for me,but i have another issue that is explained to you.my battery is falling down suddenly!i don't know what is caused for this behavior.see picture in this post!this is a normal drain after a couple of hours.but after one or more hours that is falling down suddenly to 40%! Without any usage.

Good thing you included screenshots from GSAM, so that we have something to go on now.
Remaining (Av.use) 18:51
This tells me that you once had a phone that was efficient, so from the day you realised this drop in performance, scrutinize what settings have changed (inc app installation)
Remaining (last 15 min usage) 5:47
IF u continue using your device in the way you have done in the last 15 mins, you have under 6 hours left of battery power.
In the 15% discharge since fully charged (and since when GSAM started taking this data on your screenshot), 62.9% of power was used by screen.
Some conclusions can be drawn here.
As you mention, you were probably playing some games during the 4hrs and 11min the phone was turned on(from when it was fully charged and then unplugged), very likely during the latter stages than earlier from when the phone was fully charged.
I see your screen is set on DIM, and that it has been active for nearly one hour. Your display was on for 25% of the time since full charge, and that has only used up 15% of battery.
Whether it is games or video playback, screen will be on, and looking at the data there is nothing faulty. In another words, set at dim, 7 hours or so of continuous display on sounds about right..(1 hr already used plus 5:47 expected left)
Now, if your complaint is that if you turned your phone screen off and left it that way for a few hours, came back, then found massive power drain, again, a few conclusions can be taken.
It is a shame there is no screenshot of the app usage form the exact same period. But, If you left the game app open in the background, it is possible that power is drawn still, possibly if your phone is not sleeping properly. In another words, CPU usage for game is there even when not used.
Do you have stamina mode on?
Conclusion... Form GSAM data, there is nothing wrong.
Looking at the first screen capture in OP, as you say, drain happened when phone was not awake, and screen off. I can only conclude that there was an app(s) open at the time which had been still running. If the app(s) is not closed or hibernated properly, it can happen.
If your phone felt hot at that time, it confirms CPU usage.In another words something was left open. If it was cold, even though the phone had been off for a while, then it could be faulty battery calibration.
And next time you see this big drop in charge, take screen shots of GSAM from apps and system. We would know then for sure.

Special thanks for your great comment
Fortunately,that horrible battery drainage don't happened from yesterday to now.
This means there is no faulty behavior after last full charge that i have been!
I don't know that reason but i done some actions after fully charged phone yestarday:
1.instilling Gsam battery pro as you have seen!
2.Charging with another charger(2mA galaxy s4 charger)
3.setting screen brightness to 30%
4.setting off "optimized backlight"
5.battery calibration with "battery calibration" app
This new informations from my battery behavior after 19 hours fully charged at last day from now and i hope that horrible drainage wouldn't happen in future else!

[Q] Quick Charge

So guys i got few questions about it.
Lg v10 has quick charging feature so i wanna know that how that works.
its works always, and any % ? or there is a certain point for it to work. im asking this bcus today i had 10% battery left and i plugged in its original charger with original cable which supporting quick charge. it was charging normally till 32%. i realized that and i plugged off charger and plugged back again it was still normal charging . then i again plugged of and closed phone and plugged it back when phone was off. it otomatically started phone and i entered my pin code. boom it started to quick charge
sso can some 1 explain me that quick charge?
Also that hifi dac works with bluetooth earbuds? like hbs910 - hbs 1100 or samsung level u pro ?( sorry my bad english )
Hmm... I'm under the impression quick charge only works with the screen off. Could that have played a part in this?

My V10 also meets this issue. when your phone running out of battery at 0% lowest level, it is hard to activate the quick charger, i have to replug and unplug charger many times 10 times more to activate the charge process, the screen with phone and cable keep blinking and blinking...
But if your V10's battery still remain and you wanna charge, you just unplug and re-plug about 3 or 5 times, the quick-charge will activate. I have no idea if this relates to Software or Hardware issue.
SOLVED: my cable connecting my charger and phone is broken, change the cable, issue is solved!
Well I didn't think that I ll need quick charge since I was using z2 bcus I could have a full day no matter how much I use the phone. It was charging like in 3.5 hours. So I was charging it only when I go bed. But since v10's battery life isn't that good I realy need quick charge. I waited few months for bot buying first wave of v10 but still I bought first wave I guess. Let's hope it's software problem and get fixed soon

Well for me it works all the time. When i connect my original cable and charger i always get quick charge notification and it takes around 1 hour to fully charge the battery. I recommend though to leave the phone connected on charger for around 1 to 1.5 hour more if possible. This way the phone tops the battery charge fully getting additional around 200mA charge. You can install battery monitor widget from market and you will see that the phone continues to slowly charge after telling that battery is full. This stops when battery ot charged to the max.
0% to full takes 1 hour? that is rly nice since mine takes atleast 90 mins... even it says quick charging

how long does your elephone p9000 take to charge with fast charging

Just curious. Thank you

About 90 minutes
Weird Mine takes 1hr 50m from 0 to 100%
Only 30 mins but lasts for 3 days of constant use afterwards.
I'm also surprised by these different delay...
I'm not using a quick charger and I'm able to charge my P9000 phone in 2h00/2h15.
I was waiting for a 30/45 min complete charge from 0% to 100% with a Pump Express + Charger.
I tried my phone on 2 Pump Express (not +) charger with a probe linked on the USB power lines and an Oscilloscope and it never change the power supply voltage....
It always stay at 5V.
I was thinking the phone will manage the voltage to accelerate the charging process, but nothing happened.
So, to have a complete view of the problem, I've ordered an original Elephone Quick Charger, and I'll check if there's any change about this subject.
But from my point of view, the Pump Express System is not working at all on the P9000 with the Aerom V4 or Stock ROM 20160608.
If other people have the same issue, please share it here to identify if it's a general bug or limited to some devices only.
20160608 kernel hace messed up fast charging. To me in aerom3 it takes about 70 mins from 0 to 100%
Fast charging still slow
I havent charged from 0% but based on charging times so far I reckon 1.5hrs would definitely get to 100%.
I use an Anker faster charger and Anker usb cable.
Last phone got fried with Elephone cable.
