Is it just me or any one else experienced extreme slow charging on their Droid razr?
USB charging from my PC.. It was almost 3 times faster to charge my previous lg optimus 7 and blackberry storm.

Yes....... AND....
Those other phone don't draw nearly as much power as a Razr.
So the typical PC does not put out 750mA on USB because the spec says they only need to put out 500mA. If you are using the phone while connected to USB it may never charge. It won't drain either.

Get a battery monitor app, put it on the charge, see how much charge is actually flowing to the battery... with a 1750 mAHr battery, you can guess the charging time..
From my packard bell laptop with USB charging it gets 850 milliamp...so charging time is around 2 hours.... from a Wall charger it gets 1100 milliamp, so 1.5 hours is enough....
From my HP laptop it has the charging of 450-500 milliamp so it takes around 3 hours...
I have used the manufacturer of the laptop because each USB chipset has its maximum power rating... USB 2 had 500 milliamp at max and USB 3.0 has 900 milliamp of power rating...... so it depends which chipset you are using and which port you are connecting to.....
If getting more confused, try the standard AC charger.....
Also, I think you should make sure to put your phone on airplane mode (or at least turn 4g off) and turn the brightness down while you're charging. This way, more power goes to charging and less to battery draining stuff.
AND if you're willing to spend a little cash, (or you buy your phones at Costco like me) you can get one of the multimedia dock thingies from motorola. It literally charges in 3 hours on there.
Lol.. A wall charger will do fine for me. I've been scouting for the dock, to use webtop application.. But I can't find out over here on Malaysia.
I did find a great widget, battery info, which when discharging, it will display percentage of battery left, and remaining standby time.
However, the best part is, when charging, out will inform you time left to achieve 100% charge.. Its really cool..

Math lesson!
The battery is 1750 mAh, that is milli ampere hours.
As such, it will supply 1750 mA, for one hour.
Charging is the same but backwards, 500mA is what the USB port on your PC supplies.
That gives 3,5 hours to supply the battery the required power, assuming 100% efficiency.
But lithium batteries need a trickle charge from 90% to 100%, so that last bit is usually performed in 1 hour, independent of what mAh the battery has.
So on our razr that last 175 mAh will always take one hour to charge.
So that means that we charge 1575mah at a fast speed, that leaves 3,15 hours to charge using USB, and 1 hour to top charge.
That'll give you 4 hours and 15 minutes through the computers USB. =)

Im probably not as heavy a user as some....but Ive noticed the same thing. I unplug my phone at 7:30 and plug it back in at 9-10 at night usually with 20% left and when I stay up late Ive noticed it takes seemingly forever to charge.
I believe it recommended it either the online manual or the quick start up manual to use the charger that it came with. It stated that other brands or 3rd party may not charge the RAZR fast enough resulting with slower than usual charge times.
I have even heard of some people loosing power while it was plugged in and being used. I believe the 3rd party chargers were to blame Like others have said, the USB charging taking FOREVER, a car charger is a little better but not much.
If you download Battery Indicator Pro (from the market) you can set an option on how fast you want the battery to charge via AC outlet or USB.
Will also give you a 1% increment battery display
The Motorola razr can support upto a 1000ma charger..... technically, it means that if u pop it in the wall charger it will charge at 850ma per hour... it will have a full charge in 2 hours.... but a USB port on the PC or laptop is capable of providing only 500ma, so theoretically, it will take more than 4 hours for a full charge....

I just bought razr after owning SGS1 for over 1.5yrs.
the usb charging is unnormally slow! even compared to SGS1 which has 1500mAh.
with SGS1 I used to use it for usb tethering and it charges in about 5 hours to full WHILE TETHERING!
But on Razr idle phone takes around an hour for every 5-10% of battery which is a lot!
I am wondering if there is any kernel fix or workaround that speeds up the usb charging, because this is not natural.
4 hours or even 6 hours is very reasonable charging time, but anything more than that is a lot.
I am thinking there is something wrong kernel wise.
edit: even comparing to HTC EVO 3D which has almost same battery capacity [1730 vs 1750] charges a lot faster than RAZR. and I do mean A LOT!
My EVO charges really quick for occasional boosts during the day...
How fast is the note?
From 0 to 100 over 3 hrs

Roughly about 4hrs for a complete charge for me.

How about a 15 minutes boost? does it give it a few hours of life?
I guess i'm comparing it to the HTC evo where i could plug it in for a few minutes and i get some substantial usage after.
It's a bit slow for me. 3-4 hours for a full charge sounds about right. But moderate use while plugged in to a computer it barely charges, haha...
It would be nice to have a kernel that supports rapid charging. I think Da_g mention something like that
15 minute charge isn't enough unfortunately. Samsung phones always take a while to charge I've had this "problem" with my Infuse 4G, my international Note, and now my AT&T Note. 15 minutes honestly might get you 2-3 percent in terms of battery note nearly enough for a few hours of use.
About 40% in an hour so that would be 2.5 hours for 100%. On USB it charges suuuuper slow.
I would love to see how fun it would be to charge one of those 5000mah extended batteries
Thanks for all the replies! I can't wait to get my new Note
Mine fully charges from 0 - 100% in less than 2 hours using the original samsung car dock charger. Tried a few times and always charges this quick.
takes around 3hours for me on a wall charger.
+1 on the Samsung charger. When I use all of the other micro USB chargers that I have it barely charges it. One night I put it on one of the other chargers at 1 am @ 23% and when I woke up at 6 am it was only at 77%. So I put it on the Samsung charger and it went to 100% by 7 am.

Hmmmmmm.
Last night I charged mine on my old HTC charger cuz I didn't feel like crawling behind the bed to swap them. When I woke up (after 8.5 hours of charging) I was at 99%. I suppose it could have been the stupid battery widget reporting incorrectly but my phone was down 8% in the first hour, with only 2 minutes of screen on time.
Guess tonight I'll swap chargers and see if that makes a difference.
any harm in using the Ipad charger to charge the note. i use it on my Iphone and it really speeds up the time needed to charge.
My note will be here Friday.
There may be two variables at play here - the cable, the charging source. I know with my Advantage the stock charger (with no removable cable) had an additional pin which told the Advantage to charge at a full 1 amp rate vs. the standard 500 ma available from a USB port. I think the stock Note charger is rated for 800 ma, don't have it here to verify.
Using the Note's stock cable I've seen a fairly fast recharge time both from the stock charger and my computer's USB port. Yesterday I drained down to 6%, plugged into my work computer (stock cable) for 2 hours then 1 more hour in my car and I was up to 77% after. Which included some time streaming XM via blutooth. Then plugged into the stock charger at home and was up to 100% after a few hours even though I was tethering via Wifi to 2 computers with heavy surfing.
We would need several tests to see if there is something special about the stock charger, the stock cable, or both. But compared to my Advantage it charges way faster and uses much less energy - excluding the display.

Interesting. I wonder if it's just a good low gauge (thicker, better conducting) cable, because the HTC adapters are rated 1 amp.
People who uses the charger that came with the phone must know that these chargers are really weak... They are only 1Amp... I use my blackberry playbook charger which is 1.8Amp charges the phone almost twice as fast than the regular one... Same thing with my ipad and iphone... I use my ipad charger to charge my iphone 4s and it's way faster! Use more powerful chargers! My note gets charged in 2hours top!

I'm curious to know what is the max amperage that the note can take. I know my old EVO is limited to about 950ma.
Uh...I love my Note, but it charges pretty slowly compared to my Skyrocket. It is also the first phone I have had, that can actually discharge while using it on a car charger. Especially if you are watching video or any screen intensive task.

How fast does it charge?
Sent from my HTC One_M8 using XDA Free mobile app
It says the output is 5V at 1A so it charges at 1A which is as fast are qi charges currently. Keep in mind that's limited by the best of your battery and what your phones will allow on the receiver side.
Much slower than the turbo charger. I've been using Qi chargers for a couple of years now and they're always slower than a plug-in charge. That said, it is very high on my list of must have features I look for when purchasing a new phone. If I drain the battery past 80% today I'll see if I can give you a %/hr charge; this morning I was down to about 91% and it took 15 minutes to reach 100%. The efficiency isn't 100% so you aren't going to get the rated power transfer you'd get with plug-in.
I'm using the Tylt Vu but also use a couple of others, I think one in an LG and another is the Nexus 5 chargers.

That's a given, I prefer qi most of the time because I don't like cables. It depends on how fast you need the phone charged. When I goto bed I use qi, if I'm out and need a quick boost I use the Qualcomm which charger.
Hi people
Since I'm part of the lucky people owning a Huawei Ascend Mate 7 (MT7-TL10), I'm actually looking some accessories like a quick charger.
I wish a charger better than the original one if possible, with EU pins, and with a good quality checked (I prefer to avoid some product with awesome specs but not tested ...)
So anyone have any idea where I can find a good charger, and without any risk for my phone ?
Thanks

for me I charging with Iphone charge 1A good for batter and Stander and low risk to Device
If you want proper charging, then always use the accessories coming with that product. It is tested for sure and good. Other than that, you can use any charger delivering the same charge. The original charger is 5 volt, 2 Ampere. Don't use anything above 2 amperes as it may damage the device. Below that will charge it slowly.
BTW, why you don't want to use the original charger?

Can you test it with ampere (free in gplay) i don't think it will charge over 1800mA so that it acts like a normal 2a charger
Fast charging
Using a fast charger will destroy your battery faster. Not recommended as the battery is not removable. You can get a battery and if you are comfortable removing the back and swapping it out then go for it.

that is not correct as you are not connecting the charger to the battery directly. In fact the charger is just a power supply. The actual charger is integrated into the phone (charging controller).
In general you need to know that volts are pushed to the device by the power supply and amps are drawn by the device (phone) from the power supply. Therefor using a power supply with more than 5V will kill your phone but using one with 2A, 3A or even 4A will make no difference as the charging controller will just pull the amps required. Because of that you can not really fast charge a phone by changing the power supply only if the phone supports the fast charge option (for example some Nexus phones).
I tested this myself with a power supply (can provide 5V and 1.5 to 4 amps) and an amp meter. The phone always drew between 1.5 and 1.6 amps (with and empty battery, 8 to 10% left) regardless of the selected amps of the power supply. Using a power supply with less than 1.5A will kill the power supply as the phone tries to draw the 1.5 amps or more. As result the power supply will get hot and eventually die.
Since battery is not removable be careful with fast charging, since it will decrease the life span of the battery and in the end it will just give you less battery performance.. it is stupid... however.. there is situations where it can be really needed though but not on a regular basis..
Last weekend I would really had needed fast charging.. It forced me to spend about 3 hours on a cafee so I could make it 100% so I did know I did survive the day with gps and all other things.. However in these situations I really like the ultra power saving mode..it saved me that night.. when I was lost in stockholm.. and my phone was really the only way to get contact with people

Why don't you buy a powerbank? I can advice you the xiaomi 16000mah. That one charges fast and you can be mobile.
Any recommendations?
I wonder if a S6 charger do the trick. Stock charger is too slow damn. Spending 3 hours to have a full charge is not acceptable for me.
I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v and 2 Amps. Batteries will automatically lose cells from charge cycles and by the time you feel the effects of the battery going bad, you would have already moved on to the next device for the next person to worry about. And saying to use the Stock Charger isn't really good enough as the Stock charger doesn't serve as a Car charger also. If you want to charge your phone quick, and you already have a 2 Amp charger, Check your microUSB cable. Don't use junk cables, buy quality or use the cable you received with the device. You get what you pay for. Fast Charging won't work as the Charger has a chip inside that communicates with the Phone and Device. Also, when buying a charger, don't just randomly buy a charger online, Make sure its UL Tested. Even if it says UL tested, there should be a test number on that UL Label, take it a step further and google it and make sure it matches the charger specs and passes as knockoff chargers are notorious for copying other chargers Regulatory icons to make it seem authentic. You don't want to buy a junk charger that ends up burning your house down or gives you a very bad 120 Volt shock through the microUSB cable that would also kill and fry your phone.

You have not read my earlier post or you did not understand it. Changing the charger on the Mate 7 will have NO effect (zero, nada) on the time required to charge your phone except the charger delivers less then appr. 1.6A. Then it would take longer and evetually kill the charger. The Mate 7 uses a Kirin chip which has no fastcharge implemented. Samsung uses Qualcomm Chips with implemented fastcharge technology. The charger (in fact a power supply) and the phone/CPU/charge controller need to communicate with each other, otherwise fastcharge will not be activated (the reason fastcharge with charge-only cables does not work because they lack the required data cables for communication).

Wrong. Correct would be "I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v." The amps of the charger don't matter at all -> amps are PULLED by the phone not pushed to the phone. You could use a charger with 100 or 1000 amps and it would not hurt your phone a bit as long as it is only charged with 5 Volts.
More amps (>1.6A) on the charger do not improve the time for charging one second.
1.6A is nothing. i use 2.0A and it still chrges 3 hours.

Click to collapse
Yes, and that won't change one bit even if you use the best and most expensive charger and a 1000$ cable. The Mate 7 is limited by its hardware (built in charge controller) and pulls max 1.6A. End of story.
As long as you don't understand how charging works you will spend 100's of bucks for cables and chargers to no avail.
The only reason, why charging with some charges is quicker than with others is that those chargers actually deliver the amps they are supposed to deliver. There are a lot of cheap/bad chargers out there which are labelled with 5V/2A but only deliver a fraction of the amps. You can identify those chargers easily because they get extremly hot. I use a 2A charger from Aukey which gets only lukeworm.

there's no way to disable that if you use the original charger of V10, they are rated to charge as fast as they can...you need to use another charger, i recomend you use a 5V 700mah max amperage and if you dont bother to turn off your device after plug it because your battery will get a good calibration and last a little bit longer, for sure a full charge with 700mah charger take almost 3:30 hours but it will make difference, trust me, i do the same with mine at least 1 time per week.

you should use at least a normal 2A charger. As you for sure know amps a drawn by the device connected to the charger and the V10 pulls up to 1.5A if the battery is lower than 30-40%. Using a 700mA charger might kill your charger after some time.
