Charger combatibility - General Questions and Answers

So i have a chinese android tablet. On it's back its written: "2500mA/5v". I think 2500mA is the capacity of the battery and 5v the input supported (or some kind of that). The original charger was an ac adapter with 1000mA but it's now broken. I saw in a shop a usb charger with "Output:5V 2000mA". I was wondering if i can use that charger on my tablet without damaging the device?
P.S.: Sorry if i had grammar mistakes.

I would use 1000mA again

Yeah i would too but i can't find any 1000mA charger and with usb charging the battery drains with about 5% per minute. Would 2000mA hurt?
P.S.: Thanks for answering.
Edit: Also do you know why is the battery draining so fast? And when using it for like playing Minecraft Pocket Edition it gets very hot.
And btw 5% per minute??? Do you think a factory reset would resolve the extreme draining problem?

[Q] What chager comes with HTC Sensation?

Hi,
I bought HTC Sensation as a second-hand (used) phone, and I got a charger which has written "Made in China" on it.
Although it does look like the same as I see in unboxing videos, i have some confusions. So, I tried to charge my phone with it and left it overnight. The battery was half charged in that long time and was losing charge percentage if used heavily while charging.
Since then, I did some attempts and notices following results:
>I used my brother's Sony Xperia Arc's charger on my phone and the results (charging speed) are better now.
>I also used Samsung's USB cable to charge via pc and it is also giving good results.
>When I used HTC's (so called) usb cable which I am using for charger to 'connect and charge' via laptop, it shows same result as when connected to charger.
>It was written Charging (USB) when charging via HTC charger and Charging (AC) when charging via Sony's charger.
>I can also see a noticeable difference that HTC's (again, so called) charger has output of 200mA and Sony's original charger has output of 850mA.
I understand that this makes a big difference.
Now, I want to ask that does HTC really give chargers of 200mA?
Finally, coming back to the title, how can I recognize if my charger is fake or not? Any indications etc.?
(I am trying to attach some pictures of it).
Aaaaaand, one more question!
Does battery always drop down by 10-15% or even 30% if I use camera for less than 10 minutes or is 'my' battery having problems?
Ur charger is original but I think the adaptar has problems as I do hve the same charger with 200mah it's f9 my phones gets charged

yes I am on stock ROM.
I want to buy a new charger but should I buy an htc charger with 200mah if I am given this option or should I look for a higher power, like 850mah?
And, can you tell me what is your average battery life? And what is your average charging time in hours?
Btw I have hit the thanks button, I feel like it's my duty to hit thanks whenever someone helps me
Thanks a lot for your reply.

Thanks for your reply, it's really helpful.
and yes mine also charges very fast till 80% (with Sony charger)
Do you use it continuously and heavily with very short breaks for 8 hours or does it just sleep on standby?
If I leave mine on standby, it drops only zero to 5% charge in whole night. If I use it for like 6 hours while installing apps and browsing via opera mini, it drops down from 100% to 30%, sometimes even lesser.
I bought many adapters from Ebay, and all were fakes, If you would put original and fake charger together you would see little differences like little bit moved logo. Also it depends on cable, do not you longer than 1,5m. I have 2,5m cable and it is behaves as you written, it is too long distance for it, I do not really undarstand it but it does not charge it normaly. Normaly you should buy 1A charger. I bought 0,5A external charger and it has same results as you mentioned. 850mAh should be allright but I thing that best you can do if you are going to use more USB charging ports - buy on Ebay 4 USB PORT charger witch gives really good result and best thing that you can charger 4 things at same time on your cables. I am using it all time. That was best investment in chargers. Price about 7€
All is well HTC phones behave the same way

Thanks a lot for your input. I will buy htc charger because sensation users have told me that the charger is fine and that the problem is with mine only. I don't think that length of cable can be the problem because my SE's charger is a bit longer than htc's and it charges faster. My old Nokia's charger length was also very long and it also used to charge quickly, actually it still does (on other nokias). I will buy from market.

Don't worry if the battery takes more time to charge aboove 80%, it is due to the electrolyte in the battery....the material used has that characteristic....and it is used widely...it cannot be helped as of now....

Hi mate.. Don't worry about original HTC charger.. Numbers on it are lil bit confusing but it outputs 1000mA(1A) so its powerfull enough to charge any phone out there if not broken or st..
Hello,
your charger seems ok, when you carefully look on sticker, there are input and output characteristics. For input you have 240V and 200mA (current is irrelevant for input, it is lower because of high voltage on input) and for output 5V and 1A (you should look at this value of current) which is normal for original chargers. If you have battery fully charged in 2h than you dont need to buy another one. Charging is always faster on the beginning because of higher voltage difference and on the and it slows and probably change charging type so dont worry, it is ok.
mAh is value for capacity (battery capacity based on current usage), mA is for current value (current usage, charging current etc.), very big difference...
mAh (milliampere-hour) https://en.wikipedia.org/wiki/Ampere-hour
mA (milliampere) https://en.wikipedia.org/wiki/Ampere
Regards
Thanks for your replies.. The charger whose images I had posted is still sleeping in my drawer because it charged very VERY slowly (yes, it's in caps). I thought that it was original and had some problem in that specific set. So, I bought a same new charger of 1A and I mistakenly connected in on a wall socket which was slightly loose. After some minutes, it started making noises of continuous sparks within it. So I disconnected and tried on another socket without the mobile connected this time. So the charger again produced a big spark which affected the voltage of whole house for a second, thank God it did not touch me. It now rests in garbage. Now I bought same charger again thinking that the loose socket part was my fault, but the same thing happened again when I connected it on another SLIGHTLY loose socket, where all chargers of home normally go. And I got the same results. So then I realized that I am not going to get an original one. Finally I bought a kyocera charger, for 1.5$ (converted amount) which is still working by the grace of God.

You're completely fine. I think the battery might get hot, so keep the phone in a somewhat cool environment.

I do use a 2A charger in my car because the 1A was overheating. I do always use the GPS in my car + mobile network and BT are always on.
The 2A charger can charge my phone (now) whilst I`m using the phone in the car.
The battery draws only the power it needs from the charger not the other way round so you can use a 10Amp charger if you want to without doing any harm to the battery.
It might actually charge slower as the phone could pick it up as a generic usb which will only draw half an amp so as not to over-draw a usb port. I believe to get full 1 amp charging the data pins in either the cable or charger have to be shorted (connected.)

3 amp charger.

I guess you could consider a aftermarket charger a accessory....... so ive seen on here that every one is pretty satisfied with the 2amp charging speed on our phones, I had a 3amp charger (lost it) that I tried to charge my gs3 on and the battery got really hot. I wonder if a 3amp usp port would charge the gs4 faster?? Or just be a wast of money?

S4 has a hardware limitation on charging current, right now it won't go above 1100mah while charging which is 1.1a, perhaps in future with kernel development we'll be able to raise the charging current but for now purchasing a charger above 2a would be completely useless.

On this point what you need to realize is that the usb cable loses a bunch of the power on the way... so like, a 3 foot cable might deliver most of the power to the phone ... a 10foot cable might only deliver 66% of it... so really a 2amp charger is whatthe s4 needed but going above it is kind of useless
The S4 actually goes to 1,910a when charging, I've checked with and app (galaxy charging current) that's why it charges so fast
Mine shows the same thing

Do the lights dim everywhere in your house?
Oh and guys/gals, you cannot get around Ohm's law. 2A at 5V is 10Watts. You can use a 10A (50W) PSU but your phone will only use what it's designed to charge at unless you increase the voltage which I don't recommend unless you like to smell burned electronics.
Larger power supplies do have an advantage, however. You can charge multiple devices at the same time, i.e. a tablet, phone, spare battery, all at once. Good to prepare for a storm like we had last night here.

Haha yes I figured, just being sarcastic, no harm meant.
I will add using this app I find interesting results of cable length vs. mA delivered. If you want to charge fast use a shorter cord.
I may connect it to a bench supply and see how it reacts to a gentle overvolt, say 5.5V. This could be what's needed to compensate for a longer cable, i.e. getting ~2A with a ten foot cable!

The currents which we're discussing when charging apply from the phone to the battery which subsequently uses the battery voltage as a charging indicator. Those 1.9A only happen at low battery percentages with voltages around 3.6V or lower, with raising voltage the current is limited. This is basically what QC quickcharge is. I don't really see the gimmick in it, as such a logic could be emulated in software on any phone.

long charging time

Hi, i know this subject is already exists in here, but it still have no answer. My sensation need 6 - 8 hours to fully charge from 10% to 100%, is there someone can help me to solved my problem?
This happen everyday, so don't ask me to remove the battery and try again because i've tried it.
Are you charging your mobile via a charger connected to a power outlet or are you charging via usb connected to a pc? How old is your battery?
it is a common HTC's issue after rooting the device

Has it always been like that or started happening? When mine started doing that I replaced my battery, charging times went back to normal and battery life was a lot better also.

What rom are you using. Sometimes my sense 5 rom misreads ac for usb and charges damn slowly.
Happy to help.
If your charging via usb connected to pc then charging will be half day, its because usb port is for data sending and not charging, so USB outputs very low volt charge and so device like phone charges so slow
If your charging with adapter into AC outlet, you could check if your using right cable(there are data cables where there are little wires inside so again it cannot output that power to the device and there is cables for data+charge with bigger cables inside)
P.S. Stock HTC cable provided is not the best wire....
Mine sensation is charging about 2h40min from discharge(10% - 6%) to full charge(100%)

All (good) USB chargers are going to charge at the same 5V as the Nexus 5 charger. Any charger from another phone will work without issue, but if it's under 1.2A it will charge more slowly (many are 1A). Just don't buy a cheap, poorly made charger and you'll be fine.

The major assumption here that a slower charge leads to a higher run time is not true.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
A slower charge leads to the saturation charge phase taking less time while the constant current phase takes longer. The battery in the Nexus 5 and the accompanying 1.2A charger is meant to give you the quick 70% charge that is discussed in the BU article and then trickle charge during the saturation charge. If you're charging overnight it doesn't matter which method you use, you'll still reach 100% around the same time and the runtime will be the same.
Tnx everyone, I have the original chargr but I lost is cable.
I tried many cables but that just are not fast enoug.
Any idea where I can buy one?
