Has anyone else seen this? From 100 to 90% the power just drops almost instantaneously but after 90% its normal.
Already been brought up, a lot.
Apparently when your phone charges up it stops once it reaches ~100% and begins discharging, even though it is still on the charger. People will turn their phone off after a full charge and charge for an additional 20min to an hour before they get another green LED. People have reported much longer battery life when doing this, but it is a pain in the ass.

Ahh interesting. I thought I was running into an old winmo rom flashing issue where if you flashed under 50% battery life you could never charge the device above that point.
Yea it sucks but it works... I just ordered an external battery charger since I have 2 batteries now so I don't have to do this anymore

Hmm i tried and it acted the same way.
Apparently the HTC models act like older phones did back in the day. What HTC needs to do is put something on the phone face itself when new that says "CHARGE FOR 4 HOURS BEFORE INITIAL POWER ON FOR MAXIMUM BATTERY LIFE."
Once you do this once you dont have to keep doing it. I also powered on my phone the minute I got it and activated it without charging it first and I was seeing this issue until I did a power off charge. The phone runs from 6am to 11pm without an additional charge cycle in the day and that is a huge improvement for me. I was charging the phone twice to three times daily.
How long is it taking you guys to charge your N7? At first I had the sleep of death and once it finally turned on after a slight charge, it stays at charging 0% for quite some time now. But before that, it always seemed to slow charge.

No idea. I plug it in when I go to bed and it's good to go the next day...lasts me the whole day. I also don't know how many licks it takes to get to the Tootsie Roll center of a Tootsie Pop.
At I/O they said the tablet takes about 3 hours to charge from 0-100% but it may be faster. Whenever I get the 15% alert I throw it on the charger for about an hour and it's past 50%
charge times will vary depending on the charger as well, best charge time will occur from the wall charger that came with it, USB trickle charge will take a month of sundays :laugh:
that is of course unless you have a magical USB controller that outputs 2A from each port (highly unlikely)
I wonder if its something wrong with my battery. Been on charger for more than three hours and nowhere near 100%. It was at maybe 48%. Drainage seems reasonable..its just the charge seems rather long to reach full charge. This is all from using the stock charger too...

Typically 3 to 4 hours for me using OEM charger
Via my HTC Rezound
Between 2-3 hours on charger, around 7-9 hours on usb.
My battery app says 3 hours and 40 minutes on average. That includes charge times when I am using it at the same time so I guess about 3 hours.

I don't know what happened, but with me, when I first got it it was 3 hours on the dot to a full charge. Then one day it said it needed to be plugged in to charge getting below 14%. Then I plugged it in and got the sleep of death, and plugged it in the wall and the battery icon came up, then I turned it on. Now it's been charging for about 6 hours and its only 85% :crying:
Mines generally around 40% at the end of the day, it takes less than 2 hours to get to fully charged.
Mine takes about 3.5 hours but I noticed my 10 foot micro USB cable doesn't charge fast at all. Takes about 12 hours on my 10 foot cable
Yeah I'm with the rest, mine's in the 2.5 - 3.5 range. But as stated, which charger you use makes a huge difference. Charging off the computer (USB to PC) is waaaay slow. Using the OEM wall-charger is what should give you 2.5 - 3.5.
3-4 hours for me depending on what percent I wait till, usually 5-15% battery, haven't tried with anything other than the OEM charger though.
From about 10% ie when the warning to charge came up, to 100%, took mine about 2-3 hours only last night using the supplied charger. Much longer on USB, haven't timed that.
Should I get mine exchanged ? I'm still within the 14 day policy of Mac mall. Its been an hour and its only 14%. Usually it takes 3-4+ to charge fully.

Make sure you're using the supplied charger. I believe the ones for smartphones charge at a different rate? I made the same mistake when I first got my Nexus 7 by charging it with my SGSII charger. It was VERY slow. Then I switched back to the supplied charger and everything was normal.
Usually takes me just 2 hours, and it is full. I usually start charging at around 15%. Using OEM Charger too. :good:
I used my Gnote charger but left it overnight (about 5hrs). I'd say that normally it takes around 3 hours. The battery life is awesome I have to say.

I found this while searching for an answer, my Nexus has been taking 12-15 hours to charge fully, using the factory charger. I also tried my powered USB hub (using a charging port, rated at 1.5 amp), and my Galaxy Nexus charger, same thing. Called Google today and they said it's the device, and I need to return it. Luckily I bought it locally, so I can just exchange it at the store.
I have a Nexus 4 and it will turn off about every hour and will not turn back on unless it is plugged in. I have done a factory reset and have no apps on it and it still happens. When it shuts off the battery still the 70+ percent left. Does anyone now if this is a hardware problem or something to do with Android 4.4.2?
Its due to battery memory being lost and the phone cannot estimate how much battery is left accurately.
Do a full discharge and full charge

This has also happened to my old phone. I also suggest leaving it on charge for a long period to ensure a full charge. Then do a full battery cycle. Also turn it off when you charge.

If you leave it on charge for a long period, when the phone inaccurately recognizes the not yet full battery as full(100%) , the battery stops charging. The maximum rate of input to the battery will be reduced to 0-1ma and it's not good for the battery to be in constant change.
I have this problem in my phone currently. After doing a full discharge and recharge the phone and battery will regain its limits

Last week I've installed a new usb port for my S4, because the old one broke. I know you will most likely think I've connected it poorly or whatever, but I don't think so, because I've had the slow charging issue before that.
I've got a couple of chargers. A Xiaomi 10.400 mAh charger, the original samsung AC charger, my nexus 7 charger, a Chromecast charger and a generic one from some store. The Xiaomi charger used to charge my phone quite fast. While playing Clash of Clans, on middle-high brightness I would still get about 1% every 2 minutes or so. Same with the nexus 7 one.
Right now however, it's struggling to get charged. It seems like the battery is draining faster than it's charging. But I've recently rooted my phone and installed the 5.0 GPE version rom, and my battery life has never been better. Recently got to 12h with about 2-3h SOT and still 60% left, which made me really happy. But if I charge it and use it, I only get about 1% every 10-15 minutes. Which kinda sucks.. (Right now, my s4 is on 87% and according to the lockscreen prediction thingy, it takes 1h06min to get to 100, while not using the phone)
Has anyone seen this problem before or knows how to fix it?
Do you charge it at your PC/Laptop?
My phone also charged very slowly when connected to the PC.. This was on original firmware.
Now I'm using GPE ROM but I haven't charged it at a PC yet.
There are some options in the Googy Max settings regarding charging.
What if it's the battery?

Nope, I charge it using a wallplug.
I must say it seems like my Xiaomi battery is charging my phone faster today. This afternoon it did about 30% an hour or something.
Edit: What it seems to be doing is charge fast at lower % battery, and charge slow on higher %. Is this a setting of something, perhaps?

I have an app called battery doctor which has 3 charging stages. From X% to 80% theres a fast charge, then from 80% to 100% it (supposedly) reduces the current to ensure a full charge (basically it charges slower from 80 to 100%). I don't know what difference there is in charging time in those 2 stages. But you say it happens on different roms so either you have recently installed an app like battery doctor or it's something else.
Have you tried charging the phone while it's turned off to see if it charges faster or same as before?

The only apps with root acces I have are system tuner, titanium backup and adaway. I uninstalled System Tuner, will see if that helps. And the only other thing that could do it is Googy-Max Stweaks.
I just turned the setting Charge Control Switch from disabled to Substitute AC to USB and got 7 % in 14 min. I feel it's quite a bit faster now. Gonna check it out while having Clash of Clans running. If it's still charging at 1% every 5 minutes, ill be happy
Just tested it for a bit, and went from 45 to 60% in 22 minutes. So I'm happy again
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).

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.
