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.

Hello, I recently got my 6500mAh extended battery for my N7100 and I found that charging was pretty slow with the charger that comes with it (about eight hours for a full charge) compared with the stock charger that can charge the stock battery within one hour and half. Therefore, after reading the spec of the charger, I discovered that the slow charge was come from the fact that the output amperage of the charger was 800mA (800mAh). Therefore, by some calculation, 6500mAh/800mAh which was equal to eight hours. So, I then looked at the spec of the stock charger and I noticed that the output amperage is a bit higher, 2A (2000mAh). By the same calculation, I can predict that with the stock charger, I only need about three hours to completely charge my extended battery. Does anyone attempted to use a stock charger to charge an extended battery?
Hello everyone,
So I have been trying to find the answer to what I am wondering but to no avail. I know that when using a charger that did not come with the phone it needs to have to same voltage to not hurt the battery, but I am unsure of the amps. I know for normal powering of things the charger needs to supply the same amount of amps or higher so that the item can pull enough power from the charger. However, phones do not need a certain amps to be powered by the charger. So I want to know if I can use any changer that has 5 volts, but varying amps. This is because I read that if you use a charger with lower amps it is better for the battery as it is not charging as fast increasing the life span of the battery, is this true?
Example: I have a LG G2 which uses a charger with 5V and 1.8A , but I want to use my nexus wireless charger that is 5V and 1.2A
Thanks for any assistance!
Next week getting a new Note 4 - and zerolemon 10,000mah battery!
I need to deep cycle battery 6-8 times to get phone to display the current vbbatt % correctly. The manufacturer for zerolemon says turn off fast charge and charge 12hrs each time.
That being said, with fast charge off, can I use a 5v 3.5 amp charger I see on amazon and possibly charge the phone faster than 12 hrs like normal is using a 2.1 amp charger?
Anyone tried this with let's say even the stock battery does the battery actually charge faster due to the increased amps or would it be a waste and still charges at the slower 2.1 amps?
I never deep cycled the battery and the longest discharge I got was 1 week with 16 hours on screen time...you just need to make sure you use an updated kernel with the zL fix.
The amperage rating is the max the charger can put out. The Note will draw the same amperage on either charger because they are both 5V.

But will the phone charge faster on 3.5 amps at 5v vs the 1.5 amp or 2.1 amp the stock charger puts out? I am getting ZeroLemon and need to deep cycle the battery a few times and am trying to have it fully charged in less than the standard 12 hrs - was hoping a charger with more amps would cut down on the 12 hrs lol

i just used the stock fast charger on my zerolemmon with fast charge on and i never let it go the full 1 hours. Ive had insane battery life with it so i dont think it matters

Your Note 4 will draw a maximum of 1.9A on a 5V standard charger and a maximum of 1.66A on a 9V Quickcharger. If you multiply these values, you will get your "charging speed" in Watts: The maximum is 9.5W on normal charger and 15W on a quick charger.
Using a higher rated normal charger (eg 5V/3A) will NOT INCREASE charging speed. The Note 4 will never draw more than 1.9A on 5V.
Using a lower rated normal charger (eg 5V/1A) WILL DECREASE the charging speed. The Note 4 will notice that it cannot get 1.9A from the charger and drop the current. Bad and/or long cables can also influence the charging speed negatively.
Also noteworthy: Quick charging will only work when screen is off. As soon as you turn your screen on, the charging speed when connected to a quick charger will drop from 15W to an extremely slow 5W. The only fix for this horrible Samsung joke is a custom ROM like CyanogenMod.
You can charge your Zerolemon battery nicely with the original Quickcharger that came with the phone. That will do 15W and is as fast as you can possibly charge.

Wow. Good info. Thx. Now a ton with a hack to draw more amps lol. Hmmmm lolol
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.
Hi, i've just purchased Xiaomi mi 5 and i have question regarding charging the phone. It supports Qualcomm Quick Charge 3.0 however the charger that was provided only supports QC 2.0.
I notice that whenever i plugged the phone to the charger that supports Qualcomm Quick Charge, my phone gets hot. I decided to do a little test, so I used an USB Charger Doctor that can read voltage and Amp that it delivered to the phone. I've also using Ampere to monitor my battery temperature. I'm gonna charge for about 36 minutes using Aukey charger. It has 3 ports with only 1 that supports QC 2.0, the rest of the two supports up to 5 volts at 2.4 amps.
Here's the result:
9 volts, 1.35 amps = 56% battery charged from 8%. Battery temps reach 43,2 C. Juice added, 48%.
5 volts, 1.71 amps = 43% battery charged from 7%. Battery temps reach just about 35 C. Juice added 36%.
It's clear that qualcomm quick charge is faster than the standard port, however it resulting in higher temps. And i know the fact that Lithium batteries hate high temperature. So which is the best for battery life? Higher Voltage lesser Amps, or Lower Voltage Higher Amps? Thanks in advance.
