l lost my charger and ask if could i use the lumia 640xl charger ? or it have danger on the battery life ?:
You can charge it, but it'll charge extremely slow and may affect the battery life.

I'm interested in buying an external battery charger, or a cradle charger, so I can have two batteries going—one always charging outside of the phone—and thus never having to plug my phone in to charge. After a brief eBay search, all of the cheapest ones appear to be the same: you can find the model I'm referring to here.
My concern, however, is with the specifications listed, which read:
Input: AC 100-240V~50/60Hz 0.15A
Output: DC 4.2V~350mA~±50mA
USB: 5.2Vd.c.800mA
The output appears to be 300-400mA, which is slightly lower than a stock charger. As far as I know, this tells me how fast it will charge the battery. Since it will be plugged into the battery charger when I swap batteries (for the full discharge of the other battery), I don't care if it charges slower. However, the voltage appears to be quite low at 4.2V—and I'm entirely unsure how this will affect things. Will it still charge? Can it do damage to the battery? Should I not purchase this unit? What exactly does a lower/higher voltage mean?
Anyone?
Does it work? Is it safe? Does the lower voltage matter?
I've been using this same battery charger for over a year now. It charges my stock and extended battery (3500mAh) without any problem. Yes it does take longer compared to the normal charger to charge your battery because of the low mA but I don't think it has had any affect on my batteries. So the only downside is it takes comparatively longer to charge.

Great! That's what I wanted to know. Thanks!
I have this charger as well. I can confirm that I have have not had any problems with the charger sense I got it. I ordered mine from Amazon here:
http://www.amazon.com/2600mAh-Batte...3352199&sr=8-4&keywords=Galaxy+note+batteries
I have "iball 7334i" andriod tablet it has 5v 1000mA charger and 3000mAh Lithium ion Battery and its get full charge in 3 hours.
I want to buy 5v 1500 mA charger so it get charged faster than before . I want know that 5v 1500 mA charger will affect my battery life or will it heat my tablet or will it is suitable for my tablet's battery.
Thanks
So, tommorow i get my shield tablet k1 and i wonder what is best way to charge new battery to get its maximum. i read about some 7h callibration charging and i wonder is it better to fully charge on low power charger (i have one 850mA from sony m2 aqua) or at begining with samsung 2,1A phone charger? will my 850mA charger charge battery to full in 7-8 hours?
Hi,
I noticed that when I recharge it with a charger that is only 650ma the battery last much longer than with turbo charger that came with the phone.
Even in standby after recharged it takes one hour to consume only 1% but after turbo recharging it takes about 10 min to drop 1%.
Is there anyone experiencing something like that?
Funny it is.... The case is opposite for me... Although I use Transomart QC 2.0 charger. My battery lasts longer when I charge it with quick charger compared to standard 1 Amp chargers.
That´s so weird.
I am preparing a comparison to figure out what's happening.
It happens the same here. I've a Aukey turbo charger and the battery drains faster

I also got Aukey and it's the same
There's no way to actually know the charge (in mAh) of a battery without draining the battery. The way that phones estimate the charge is by measuring the voltage of the battery. Quick Charge 2.0 (supported by the Moto X 2014) uses a higher voltage to charge the battery faster. This can make the battery hit max voltage before it is actually fully charged. That is why Quick Charge always advertises how quickly it gets to 80%. To get to full charge (not just when it shows 100%, but when it is actually fully charged) will take about the same time as a standard charger.
Heat and Turbo charge destroys your battery.
if i turbo charge , my phone will suddenly die when it's between 10-20%. W/ regular charging I get sudden death at 6-8%
i use a moto razr 850mah charger and solved the 8% sud power off, took 2 charge cycles from death to 100% leaving it overnight. Now battery works as it should
.
As I've been reading around (can't recall specific scientific data), the faster you charge the battery, the less capacity it can hold. So it makes sense that it lasts longer if you charge it slowly. I don't know how much would be the difference tho.
It is normal in my opinion. Slower charging is also healthier for the battery and usually will last longer
Has anyone ever used a wireless charging pad with the phone. I bought a stick-on one from amazon and it charges fine,,,slower but fine. However, I noticed that it tends to get suck at certain levels and if I take off the wireless charger at say 89 percent,,,it takes less than a min to go to 100 percent charged?
Recomendeed is charge with Motorola original charger of this device, i mean 1150mAh dual port charger
Anyone here with experience of using Motorola's Turbopower 15 wall charger? I'm thinking to buy one, because waiting for 1 hr to charge to 100% is quite annoying.
Hello everyone!
I recently purchased a Mi note 5 pro that comes with a 5V,2A charger out of the box.
While using it I realised the phone started warming up while charging with it- The phone reached a temperature of 42 deg C (well, the device got significantly warm).
Concerned, I tried out an old Samsung charger (5V,0.7A) with my Mi device and realised the charging temperature was much less (35 deg C) (here, the device remained cool).
Well, I wanted to know:
- Is it safe to charge the Li-ion battery at low charging currents (voltage is constant at 5V) ?
- Is it okay to use a different manufacturer's charger with my device (even if the charger is a genuine one)?
Also,
-I don't have a problem with longer charging times
-I frequently keep the device plugged in and maintain the charge between 20% and 80% (and full charge cycle once or twice a month)
-I am a heavy user but I avoid using the device while it is plugged in
-AccuBattery was the app I used for battery measurements
In the end I'm just curious to know how to prolong the battery life of my device and I'd really appreciate the help.
Thank you
1. Yes it's absolutely fine to charge at a low charging current. It is in fact better for the battery to charge it at a low current.
2. Yes, it's also absolutely fine to charge with different chargers, the quality of the charger is what is important.
