Why does this charge so SLOW?

I am completely satisfied with my nexus 7 but it seems to be charging ridiculously slow. So slowly that even browsing with my screen on low, my battery still goes down while its plugged in. And a 1 hour charge with my nexus off only charges it like 20 percent or less while my samsung galaxy player charges 65 percent. I have tried 2 different USB cables and chargers.

considering theres much less voltage going through when using the usb(not wall charger) to charge, its normal for it to charge slow. and normal for it to lose battery % while charging it via usb and using the device.

Get a HP touchpad international charge kit from Amazon one of the members recommended it to me, it charges in about 2hr 45 minutes full charge faster than the official Charger. Make sure u turn off or nexus to charge the battery faster

Be careful as the faster a battery charges the hotter it gets and the hotter it gets the faster it's performance and life decrease (all batteries life and charge levels will slowly decrease over time and after soo many charge cycles as parts of it very slowly kinda burn out and are unusable). Also why even fast chargers SHOULD slow down when you hit roughly 90 - 95% as it is not good to cram power that fast in to lithium ion when close to full as this causes the loss of parts of the battery more quickly. Usually it can be apps that can slow things down as well. like my boss kept complaining his phone are 3 batteries a day until a week later I convinced him to get rid of unneeded apps and low and behold it came right back. This is due to apps requesting what's called a wake lock basically telling the device to not go to sleep. This is needed to do syncs, scans and the like, but poorly written apps can juggle wake lock poorly causing bad battery usage when they don't need to.
My tablet charges in roughly 2.5 hours from dead to full using stock charger which is GREAT for a 4000 maH battery.
I also highly recommend turning the OS off and charging via charge only screen (where you see only battery graphic filling up) that would not involve any apps messing with the device while charging.
Also not good to leave device on charger longer than roughly 30 min past full as this could then have charger throttle between fast and slow charge over time (usually due to imperceptible power fluctuations tricking the circuits in the charger to reset and it takes it a sec to realize the battery charge level and adjust back) while battery is full which is very bad to have it in fast charge when it's full as stated (the charger not talking of what some folks call a fast charge mode on some devices (usually used in some way to speed up charging when using a computer USB port)) and is why even manufacturers will warn you if this sort of thing (that is if you read caution statements or manuals)

Very true depends on how hard you are running the device. Streaming movies in this mode most likely you will see a loss while simply checking news feeds or light internet browsing it still gains percentage.

The battery in a nexus 7 flo is a Lithium ion battery (as one would expect). This particular kind of battery lasts longer if you top it off all the time (Meaning you should charge it whenever you can).

I did some reading on battery university some time ago and concluded the best way to save battery health is to keep it as much as possible between 40 and 80%, as well as try to not leave it full or completely discharge.
I've been using this method on my phone for more than a year and the battery hasn't noticeably lost capacity.

I charge it whenever possible, Battery nowadays trickle charge so always plugged in does not damage battery longevity. Install Gsam battery monitor and you will see even during charging the battery doesn't get much hotter than 30C and Lithium batteries is fine at temps below 45C.

+1 for me. When I pick it up to use it, I like it a 100% charge. I don't always know when I first disconnect it, if I am going to use it for 5 minutes or 5 hours. If I waited until it called for a charge and picked it up with, say, 25% power, I would be screwed if I wanted to use it for a long period of time. I wish they came with swappable batteries like a phone, so I could get a couple of spares, keep them optimally charged and then switch when the one in the N7 got low. Alas.

I charge mine while I sleep. Haven't ran it dead yet.

Best solution is a portable power pack, it just adds some extra bulk. Someone will eventually release a battery pack case to take advantage of the wireless charging.
Is it still the case that the earlier you recharge, the longer your battery will survive? I haven't run my Nexus 7 into the red so far, which is pretty easy to avoid when it lasts for longer on one charge than I could ever imagine using it non-stop.

There was an article on Gizmodo that recommends not to let it go below about 40%. I would post a link, but XDA's not letting me.

This. You guys that are allowing it to reach the point where it tells you to change are causing premature wear on your batteries, especially if you allow it to reach the point of turning itself off. Nothing is going to immediately fail, you're just going to start wearing out your battery faster. We'll all eventually reach that point of reduced capacity or inability to accept a charge.

I try charge my devices before they hit 50%. Doing so will about double the longevity of you batteries. Of course their are times when this is not possible, but with a car charger and several QI wireless chargers it not a problem most of the time.

Only up until 80%. If you have to charge close to 100%, at least try not to leave it in that state for long, since that's what damages the battery. Also, try not to discharge below 10%.
Of course, these are all just guidelines. You battery will degrade anyway, it's just a matter of time. There will be minimal impact if you do a full charge-discharge cycle from time to time, but the less often you do it, the better for your battery :good:

Avoid using extended battery life.. Charge your phone til 100% and used it till gets to/around 10% and then charge it again so that the charging cycle is fixed. If you are rooted make a full wipe and install any ROM you like with some good kernels out there that matches the ROM. :good:
It might also be a rough app that you recently installed. Use BetterbatteryStats or Wakelock detector this will show you what is causing the unwanted deadlocks and causing battery drain. :good:
Hope this helps you.

Hi I'm new to nexus 4 and have a battery question. I didn't want to start a new thread. I bought a slightly used nexus 4 and charge it to 100% after only a minute of use it immediately starts to drop. Is this normal? I ask because I had an HTC sensation that I charged to 100% and could at least get 10 minutes of use before battery started to drop. Is there something wrong with the battery or is this just the way the nexus 4 operates?

Nexus 4 works this way.. Its all right if battery drops in a minute.. There are plenty of process and their corresponding syncs that actually causes the battery to drain.. Try some different kernel all are good you will get more battery backup.:good:
BUT Stock Rom + Stock kernel are THE BEST.

Maintaining battery health requires a bit of a balance. You don't want to frequently do deep discharges, but you also don't want to charge your phone every time it drops by 10%. If you're sitting around with a charger, plug your phone in when it hits 50%, then let it charge fully before unplugging it.
Overall though, batteries just degrade. You're not going to have a huge impact on the health of your battery unless you're charging it every time it hits 95%.

How about using a slower charger over night? I believe the OEM is what, 1.2amps? I have a couple 1amp chargers from previous phones I had. Will that charge slower/safer?

Modern lithium ion batteries are fairly robust and more chemically sound than early rechargeable batteries. However they do have a finite number of charge cycles.
But you have to understand what a charge cycle is, a full drain to 0 and charge to 100.
So for example Draining to 50 then up, then 50 again then up= 1 charge cycle.
So... Draining it to 95 and bumping it to 100 would take 20 times to reach 1 charge cycle.
Trickle charging vs the oem power used isn't going to make much difference either.
Being ocd about the battery is just going to make you pay more attention to it and thus making you more aware of drain...just use the darn phone and enjoy it!

there is no right way. plug it in when you need a charge, or when there is just a plug around and you want to top off. you do not need to discharge battery to a certain point then charge. just charge it whenever. all these other theories are just that, theories. at work all day, i bump charge it whenever i reach around 80-85%. my battery has not gotten worse. and when im not around chargers, my battery is built to last. i average around 5.5-7.5 hours screen on time, depending what im doing, and im a heavy user.

truth.

The battery will only be able to take 1.2 amps or what ever, for the first 10% or so of battery life. By 25% charge, its only sucking around 750ma, and by 50% you are lucky to suck a half amp. Lion batteries do not charge via constant current, they charge via constant voltage (with the voltage dropped for 25% battery charge or less due to over current). So as the battery charges (aka increases in voltage) it draws less and less current.
You want a tip from a guy that has to run the lion battery analyzer for flight modules, keep your battery between 15% and 85%, and long term story them around 30%-40%. A pack that is left on a good charger ($75 or more) charger and never gets below 98% will loose its capacity at double the rate of a pack that floats above 15% and only gets charged to full when needed.
Ive had packs in the field coming back for recal from 2003 still holding above 90% rated capacity because they dont leave them on the charger and dont let them go dead in a locker some where. On the other side ive had 2 year old packs come back that are at 80% capacity ( i fail them at 85%) or less because they sat dead for a year.

Fast Charging Issue

Yesterday I have my curiousity and uncheck the fast charging option on settings. I turn off my note 4 and start my charging. I started to charge at 18% and after an hour it go up to 23% which is annoying. I decided to turn on my device and tick the check box of fast charging option. I left my device for 2 hours but to my surprise it was only at 54%! (device off). I turn on again my device to check if the fast charging is activated and found out that it was checked. I left it again for 2 hours and still 72%. Anyone experienced this? Any advice? It will be so much appreciated. TIA.

Something was probably running in background. Restart your phone and try again.

Maybe your cable is the problem.

Did you use original charger and original cable?

I don't think fast charge works with the phone off...

Make sure you are using the original charger and cable from Samsung. Otherwise it could be the chargers problem as it doesn't provide enough voltage.

No, it does not. In "normal mode", our power supply provides about 2 A of charging current. Taken losses by generated heat and less current needed for charging the last few percents into account, it takes about 2 hours or a little more for a full charge while the Note 4 is switched off. NOT 8 hours.
8 hours is a realistic value if you use a low power current source, like a standard USB port providing 500 mA of current.
500 x 8 = 4000 mAh; and that's quite exactly the amount you need to push into the battery to achieve a 100 % charge.
So your 8 hours refer to charging with a low power device like a standard USB port, but not to charging using the original power supply AND (!) the original cable. Yes, the cable DOES make a difference.

Not all energy goes into charging the battery; there's a good deal wasted for generating heat; that's why your Note gets a little warm while charging.
Fast charging provides a charging current UP TO about 3000 mA, that's the safety limit. Our battery has about 3220 mAh capacity.
The charger provides that current till the battery is "almost full", that's at about 92 %. ("About", because it's not the same every time, depends on several factors.)
After that, the current is lowered, so charging from e. g. 92 % to 100 % takes considerably more time.
So even if you get about 50 % in 30 minutes, a full charge to 100 % takes far more time than 60 minutes - because the "last mile" takes far more time than charging up to e. g. 92 %.
A continuous fast charge of 3000 mA up to 100 % will kill your battery.
As said, there's heat generated while charging. That heat does not fill the battery, so we need to deduct the energy wasted that way.
That's why it takes about 90 minutes for a full charge. Could take more time according to the battery drain of apps and processes running while charging. So fast charging times of 90 to 120 minutes or so are just plain normal.
And that's why it's simply impossible to charge the battery up to 100 % in 60 minutes.
I know it's tempting just to multiply the time taken for a 50 % charge by 2 - but that's not what's happening in reality.

In Germany, we have a special term for things like that; it's called a "Milchmädchenrechnung". Translation would read like "a naive calculation made by ignoring vital facts".
There's a lot of vital facts you ignored. Shall I start with you claiming that 14 hours is the best charging time ever? Or with you claiming that Lithium Ion batteries use "trickle charge" ?
See http://forum.xda-developers.com/note-4/help/note-4-question-charge-t2989546 for the full coverage; enjoy.
Now let's concentrate on the Milchmädchenrechnung above.
First have a look at this - I guess we can take Anandtech for quite serious: http://www.anandtech.com/show/8613/the-samsung-galaxy-note-4-review/3
Further down the page, under "Charge time", you'll find this statement about the Note 4: "... and most of the benefit would come from the first 50% or so of charging as power drops rapidly as the battery approaches full charge."
The red part is the part you didn't understand, leading to your Milchmädchenrechnung.
You took for granted that the power (amperage) doesn't drop at the end of the charging process; I guess you simply didn't know.
And that's the important factor making a full charge in just 60 minutes completely impossible.
Did you really believe Samsung would miss the chance of presenting a sensation like that in all media you can think of ? - That would have been the fastest charging mobile phone ever known. CNN would have broadcasted a special feature about that.
They did not, Samsung did not.
Reason: It's just nonsense.
dont listen to chefprol - he knows nothing about electronics or batteries.

I guess I don't need to comment on that.

14 hours was the time i recommended a NEW phone be charged for the FIRST charge. i normally charge mine for about 7 hours with a single coil Qi charger. Because it takes around 7 hours (5 for a 3 coil depending on power input) for a Qi charger to go 0-100.
lithium ion batteries do use trickle charge. they top up the battery if the phone is above 90% at a slow charge rate. hence "trickle".
No i did take into account that power drops at the end of the charging process. thats what the extra 864mW is there for. Thats waste heat+headroom. maybe you can show YOUR calculations which are not so naive. oh wait, you cant. because a simple wall clock will tell you that the note 4 will quick charge in an hour in regular use.

Turbo Charging on the Moto X Play

The Motorola's turbo charge claims that it can charge a fair amount within 15 minutes from 0%. Faster than the S6 apparently, is this true? If so to what % from 0% within 15 minutes?

That was the Style they demonstrated not the Play, I dont think the play will charge faster than the S6 only because of the bigger battery.

Moto X Play does have turbo charging. That's what it says when i plug it in. Expect 1% a minute.

I'm not saying it doesn't. I'm just saying dont expect it to charge faster than the S6 because of the battery being bigger on the Play.

Probably will last longer than the S6 though.

Ideally. Though I'm finding this phone has a lot of wakelocks going on and there isn't a whole lot we can do about it until we get root.
Once we can root and install Xposed, I think we'll have some pretty amazing battery life on this thing with the right tweaks. I can't wait.

I don't use any battery apps because I'm not rooted. I just go by the built-in battery graph. On other phones (where I've rooted and controlled wakelocks), the graph is very horizontal when the phone is in standby. On the Moto X Play, my standby tends to have a steady decline on the graph of roughly 15 degrees.
I don't have any example screenshots of the Moto X Play yet (just unplugged it from the charger), but here's an example of the standby I was getting on my Galaxy S6:

Trying using a normal charger and see how slow it charges.
I don't how Moto says 48hr battery.

Google services doesn't usually even show up on mine. How much are you using Audible?

Here's my current stats. Haven't seen much of a difference when charging with the Turbo Charger or a normal one.
One app that does use a lot of battery though is Spotify

Hi Guys,
I just bought a new Droid Turbo and My Friend bought a new Moto X Play. I am coming from using various Motorola RAZRs and in general about 2 years of rooting flashing etc. I think this thread went stale, and you guys probably have gained much more knowledge but still thought might share few of my learnings. Please ignore if the things i mention have been covered in other threads coz am new to this device so haven't read any other threads. Hope these things help.
Turbo Charging-
Turbo charging is indeed quite fast. My Droid Turbo 3900Mah battery charges 0 to 100% in 120 minutes. This is quite fast considering my RAZR 1750Mah batter charged o to 100% in that time on a normal charger. I haven't had the guts to try but i am assuming the charging on non turbo chargers will be slower. Having said that let me go into more details. Standard charging is 5V 1A so 5x1=5W. So that is like really slow. USB 2.0/3.0 charging is 5V 0.5A(I think it will take days to charge our phones with laptops) But there are some chargers which have higher ratings. I have used travel chargers from samsung, sony and motorola which all have ratings 5V 1.5A or 5V 2.0A. So they are 50% or double speed chargers. These used to be harmful to the battery back when batteries were small like on my RAZR. An Ipad charger adapter is 12W, 5V 2.1A. Have been using this for RAZR since 2 years now. I think it broke my battery but it was a good 2 years . The New Motorola Charger is also 12W. But its not just the high current or rating. It also has technology to accelerate charging in the phone itself. So I assume a non turbo 12W charger would not be too slow, but still slower than turbo. I am guessing it should take about 2 hours for 0 to 100% Do keep in mind though, like iphone and samsung, the turbo charging stops after 70-80% I don't remember exactly when but its never turbo directly up to 100. only a jump start push as batteries are exponential in charging and discharging.
Battery Life-
I know the phone says 1 day left and 2 days left but you never know when you suddenly have to do stuff and all battery is drained out. I am coming from a 4.3 inch screen so i am assuming these large devices will eat more battery as well. I was always using custom roms and blocked wakelocks, used greenify etc so stock system is like new to me (and pretty frustrating too ) When you are actually using the phone, of course the battery will drain faster. The screen uses a lot. Data usage should use less battery with wifi on. But i mostly dont use wifi and am continuously on 3G. So even in 3G, battery drains faster only if background apps are using lot of data. But usually the standby is much better if there is not much use. I used to go 10 hours on 3G on my 1750 Mah RAZR (Ofcourse with all the root stuff) But until there is no root, 2-3% per hour drain is to be expected when phone screen is off and like its on standby, you arent using it actively. For example you are working and the phone is away, or you slept off at night. The drain should be under 3 or 4. If its higher, there is some app that is draining the battery. And without root we obviously cannot trace down which app is keeping the device up, but if you click on the battery graph and go to details screen - you will see stats below like how long the device was awake, when was screen off etc. Something is keeping your device up if the the device wakes up a lot even when the screen is off and you werent using it. Greenify without root also is quite good at stopping non system apps from hogging battery/data. But of course to go more than that, you need root.
Rooting
I am not sure about moto x play, but i read up on some droid turbo threads and they sound promising. I am coming from a always bootlocked RAZR and it seems like a relief that these devices have an unlocked bootloader. I am still confused about rooting and using custom as the phone is new and i really like the feel of it. But i am sure i will eventually root and put something custom on it. Of course rooting might void your warranty so take care!! Always read up on stuff, and read up a lot. Never trust just one thread with instructions and always (and i mean always) first learn how to fix broken/bricked/wronglyflashed phones before you start rooting and flashing stuff. And for phones like ours without removable battery, never do rooting flashing etc if the battery is below 50. Trust me, i have gone down that road too many times with my RAZRs where i always ended up tearing up the phone and exchanging batteries to revive the phone again.
Android in General
I am sure this thread/device/forum has amazing devs. I already found some amazing devs for turbo too, so i expect the same love i got for RAZR from XDA community. But in case you guys ever have any questions you can always shoot me a message. I am not an expert or anything even remotely close to that, but i will try my level best to research stuff for you so that you benefit from it. I am sure you can also gain the same knowledge i had by reading up all pages of all threads for the device, but in case you cannot find anything or do not understand just shoot me a PM. I am a loyal Motorola user and damn proud of it and always ready to help fellow moto followers Enjoy!

My phone is not Turbo Charging anymore. Same powerbar same Turbocharger as before, same USB power cable from charger to the phone. I did a hard reset on the phone, and the phone has the October Patch applied. Any ideas? Before it was saying Turbo Charger connected, now it just says charging. Anything I can try? And is really fricking slow when charging.

Use Ampere app to check the amp that your phone is getting. Try using different USB cable.

I have seen max 1090 miliAmps and min 870. Seems to be back to normal-ish just not saying Turbocharger connected.

If you are using custom rom it wont show *turbo charging*. Still it will turbo charge

On stock rom, not even bootloader unlocked.

I changed the place of the charger on the power bar with the Ampere app open and in the old socket was showing max 500 mAmps while in the new socket the charging current jumped to 2300 miliAmps! Wtf? Now it says rate of charging : Turbo! The socket on the same power bar gets tired of supplying current? Wtf?
