Charger problem? - HTC Sensation

I bought a HTC Sensation from a guy and he didn't give me the genuine charger. The phone charged very slowly(6 from 1% to 100%). Since than I have tried many chargers(not genuine) and with nearly the same result. I than installed battery monitor widget. I see that while the phone is idle with the screen off it charges maximum 350mA. If i play 3D games in the meanwhile my battery goes down.
My question is how much mA does your battery charge when idle? How long does it take to fully charge? Is there any charger that I can buy from ebay or amazon that you have tried?
Sorry for the long question.Thx in advance

350mAh is very low for a maximum. How much mAh a charger uses to charge the battery depends on the battery level itself. If I'm down to say, 20%, my charger will charge at a rate of around 900-980 mAh. As the battery gets closer to full, say 90%, charging will taper off, and I might see about 200mAh.
Any charger rated at 5v - 1000mA (1A) will be what your after. I got an Australian certified charger off eBay for $10 and it does a great job.
My phone from say, 20%, on average will take around 1.5-2hrs to charge to 100%
Here's one very similar to what I bought. I had to buy one because my phone was purchased from Singapore, so obviously it didn't have the right adapter for Australia.

I bought that anker battery that everyone keeps talking about and I have to say it works great although my phone takes a little longer to charge now (I'd say between 2.5 - 3 hours for a full charge). I'm currently tackling a new issue though, since I installed stable CM9 (a week or so ago) the battery will last most of the day but not the whole day where as CM7 would make the battery last a whole 24 hours. So around 30% less time with new rom!
I used to work in a phone shop and found that most USB micro chargers will be ok (from HTC, samsung and blackberry phones) and at home I either use the official HTC charger or a blackberry one.

[Q] Emergency Battery Charger

Hi Guys,
I am looking for an Emergency Battery Charger for Desire HD.
Mainly i want something on the cheap and light to carry. Here is what i have found. Please help me, which one should i buy:
1)350MAH EMERGENCY BATTERY CHARGER

4)1500mAh Extended Backup
http://cgi.ebay.co.uk/Extended-Back...709?pt=LH_DefaultDomain_3&hash=item45f6a04fa5
the first one seems rubbish, only 350mah? and the output current is half that of a usb port.. i don't think it will even charge your phone at all and probably only slow down the battery discharge.
I've found this one:

i bought the first one (it was really cheap) and have it on my keyring with my keys, yes, of course it only slows down the battery dying, what did you expect? it is a tiny battery for EMERGENCY use, not a backup battery that can fully charge your phone multiple time for god's sake!
anyway, from 15% battery it charged it to 80% in about 35 minutes
Not a particularly cheap option but I use a Powermonkey Traveller. Although it was relatively expensive it can charge 'almost' anything with it's range of adaptors. It's seen me through many a smartphone, PSP, DSi, camera emergency!
Just my thoughts...

the product says: "You can charge this charger by USB or Sunlight."
USB ... >> OR << ... Sunlight ?
what does that mean? if the battery charging through sunlight i'm not able to charge the phone? Or won't it be possible that the battery charges throught sunlight while the mobile is charging ?
work that thing only with sunlight oder may with roomlight too?
thanx =)
have order there freeloader pico
Will let you know how i get on once i get it!

It means that the external battery can be charged by USB or sunlight: I've tested that if it's charged by USB in daylight is more rapid to charge it.
If the external battery is attached to the phone, the phone charges itself and if the charger is under sunlight it charges itself.
thanx =)
and will it only charge under sunlight or maybe in the room too ?

So let me get this rite. U used the first on to charge from 15% to 80% in 35 mins... if this is correct then it is perfect!!
Just a question. Did it ran out of charge after 35mins, if not how much u were able to get out of this.

massive 5000mah battery (charged my DHD twice and still had juice). only thing it its quite big and heavy. works well though and if you have 2 USB cables you can charge 2 devices at once. came in useful when my girlfriend forgot her charger when she stayed over. definitely not something to carry in your pocket, but for leaving in a bag it cant be beaten.

Hey man, did you complete your work or even start whole trade of yours
Not the cheapest but will charge almost "anything" and it has a 5000mAh battery, go to Amazon and search for Veho VCC-A007-PBP Pebble.
I use this 5000mAh battery pack. It works very well, I get about 4 full charges from it and is able to charge 2 devices at the same time.

HTC chrger VS Samsung Charger

before i got my galaxy s i used to own the htc desire,
now when i charge the galaxy s with its own charger i never get more than 12 hours of standby and the battery just dies
with the htc desire charger i get more than one day of battery life, actually now after 1d 45min since being unpluged i still got 42% of battery life (with the exact same usage as my everyday usage)
now after checking the output voltage in both i found out that they both output 5volts , but the galaxy s is 0.7 amps, while the desire is 1amp
so do you think that i should keep using the htc desire's charger to charge the galaxy s, or this slight increase in amp can damage the phone.
by the way , i tried 2 different samsung chargers , and they both give me no more than 12 hours of standby time , so i know that i do not have a problem in the charger.
any help will be appreciated
thanks
You are tempting me to buy a htc charger as I am dying to get it past 12 hrs of usage.

Thanks in advance! .)
My Samsung Charger just stopped working and I only have my HTC HD2 charger to use so I haven't got a clue. Just shows how rubbish the Samsung one is though i barely used it as it is and its broken.
This is very peculiar to me.
The charger shouldn't be making a huge difference, but the way I see it, if the charger is output more current to the battery in a faster period of time, it might be charging the battery "more" or over charging, or the samsung undercharging.
The battery life of a phone SHOULD be determined by the mAh rating of the battery. and if both chargers are charging the phone until "100%" then they should not be draining at different rates.
The best way to test this is to get a sustained load and put it on the batteries and see if they match up to the rated mAh ratings. I wish i was still in school so i had access to this stuff so i could test it.
who cares if more amps cause damage, the only damage it will cause is to the battery.
the average battery should last the same as the phone - say 3 - 4 years ??
so if using the HTC charger ruins the battery is 2 - 3 years, who gives a **** lol, aslong as my battery life increases, im happy to buy a replacement charger in 2 - 3 years, BUT by then i would have moved on to another device anyway.
I say if it works, USE IT !!! to hell with the consequences, live life to the max !!
Thanks for sharing this info. I will give it a try with my friend's HTC charger...
Just to add to this.
USB outputs 5v +- 10% & between 500-900mA so if you charge via USB this would have the same effect would it not?
thanks alferret for that info , i really wanted to know that, so now i guess there's no harm in using the htc charger,
i am using it now as my phone charger , and i am getting no problem so far
thanks
Guys if your charger breaks the problem might be the chargers plug or mini usb (iv bought a cheap charger and it was charging but i could not use the phone literally i thought iv burned the screen)iv opened up mine and one of the wires(mine was the black one)was detached try opening with something sharp its really easy to do
just try it those cables detach really easy
Or if your really lazy buy one if you wanna
Funnily enough, yesterday at work I used a Sony Ericsson charger, just top up my phone a bit. Went from 80 to 100 percent in virtually no time.
Strange. I will check my chargers at home
Mine too , after one month and i`m using an LG charger

On Motorola and HTC phones (maybe others as well), chargers are a Micro USB cable with a USB adapter. I wish Samsung would do the same. Much more eco-friendly.
Thanks for the info. I will give it a try with my wife HTC charger.

[Q] portable charger or extended battery?

i am going on a travel abroad... will be using camera and camcorder a lot and wifi.... what do you recommend? a portable charger or extended battery? i want a cheap solution..preferably available from ebay
budget : not more than $30-34
extended battery
Battery will do better
I've just come back from holiday and had a portable charger. It was useful, but I often found that the battery would hardly last the day and there wouldnt be any place to charge it (you don't really want to be back in your hotel when you could be out sight seeing). Rather than trying to find a socket, I'd just get an extended battery. You can just swap it over and continue your fun rather than rooting around for power.
if i buy an extended battery i need to also buy a seperate battery charger so that i can charge the 2 batteries at the same time
it depnds how you'll spend your time.
but you can swap the battaries on the phone to charge them.
Normally charging the battary will last 1 hour.
again it depnds about the places you'll visit.
How many mAh are you planning on using per day? An extended battery will give you 3000mAh compared to the 1400mAh on the original battery. A decent portable charger will give you 5000mAh.
The only down side of using the portable charger is waiting for the battery to charge, most will do that at 500mAh so 3 hours to totally charge the normal desire battery from flat. However while the extended life battery has died the charger will still have about 1.5 charges left in it.
1 thing to point out unless you get a solar charger some portable charges will only charge from USB so make sure you have a way to charge that when out and about
I would get the potable charger (and remember to put it on charge when you have a spare min throughout the day) as when you replace your phone you cant really do much with the extended battery with your new phone, least the portable charger can be used over and over again.
i finally opted for a spare battery solution. I bought an oem battery for desire/nexus one. and i will buy a battery charger so that i can charge both batteries when i go to sleep so that they are both ready the next day
Get a portable charger instead. Taking the battery in and out can wear off the back lid easily.
Get a big battery, it's better than changing between batteries. As well you have to carry the portable charger when you travel. And you have to charge it, too.
So the extended battery should last one day (except you use GPS all time) and you can charge phone when you sleep.
I use a proporta turbocharger and I found it more usefull 'cause I can spare it with my friends with Desire HD, iPhone 4 and LG Optimus 7: with 2 of this we managed to stay all charged all day long and recharged both of them in hotel during the night.
For a trip is a Extended 3000mAh Li-Ion Battery a good solution. It comes with battery cover. Price about 25 $
For the daily use, its too big for me.

Extended battery for sure.
can aosp/sense kernel recognize bigger extended battery? afaik, there is a problem when charging bigger extended battery.
in my personal opinion, the standard battery (htc original) is much better than other and my desire remain slim. and if i travel, i prefer to use big portable charger to charge the handset when is not used. and charge them both when i sleep.
Most batteries with lots of ampere just have them as a tag... Check this site for information:
http://batteryboss.org/
I suggest you buy another original battery as from time any battery will lose capacity and this way you are flexible.
To charge you can buy a cable designed for charging the smartphone from your car e.g. HTC CC-C200 or the car dock from my signature.
Why you should use this: The data line is used for power and not for data and therefor the charger is recognized as a wall charger, not as usb cable. Thus recharge is lots faster (with 1000 mAh) than with any 3rd party charger/cable with 500 mAh although the charger itself could give you 1000 mAh (USB specifications!).
I'd go with an portable charger because you don't acutally need to restart your phone when plugin it in.

Thank you very much for the info.
I use a car charger (not HTC) which gives 1000 mAh and even with the original cable that came with desire, charging is slow. If I get this right, it is fault of the cable, right?

I suppose, best is you try it yourself - maybe a mate got one. As you may know USB allows only 500 mAh, using that secial cables that don't comply with USB (as they only charge) the producer can avoid this restriction.

Battery Care P3110...

Hello Guys!
I got today a new P3110 and I discacharged it to 2% and I plugged it now to load.
I have seen the charger pushes 2A @ 5V , this is pretty much for a battery of 4Ah, I know from my batteries ( AA AAA and others) that the charging current should be max. 1/3 of the capacity of battery.
So my question is: IS it better to charge it with the Samsung Galaxy S2 charger which provides only 0,[email protected],1V ?
It would last app. 6h to charge it till its full ( can be done over night, hopefully the charger wont melt)....
What do you think about that? Woul it harm to battery(li poly) to do it with small current?
cheers
If the charger seems much then tell me why Samsung made it.

Battery life span is a matter of charge cycles 0%-100%-0%. That is 1 cycle and surely batteries don't discharge to 0% not charge fully to 100%
-AFAIK- Even with lithium, Its the heat build up when "fast" charging that shortens any battery life - (same with fast discharging- I would never use those apps that do so) , so I agree with shOne. I have the same model & have noticed the battery does get quite hot when mains charging,( though have never thought to check charging AH).
I would imagine that the only damage you would do with using phone charger would be to the charger, by sucking out more than it can handle, not the battery ! -
-- But why not charge it via a pc usb port - this take a lot longer (so presume much lower AH) than the mains plug in charger - Most usb pc ports are nowadays - permanently live, even when pc off - same with the usb on a modern sky/virgin box. My battery does not get hot, charging this way. I dont know what the charge rate is charging this way ,because both the inbuilt notification & my battery app say "discharging" - (although actually charging)
(I agree that Samsung have provided a quick mains charger, and wouldnt be averse to selling replacement batteries earlier than would otherwise be neccessary, !! (I wouldnt use cheap replacement batteries in any I.T. stuff - I "blew up " a laptop once as a result!!)
I believe that the 2 amp charge is reasonable with the out put of most lithium batteries for this type of device. Since it is a lithium it will not be overcharging or over heating due to sensing, it would be a serious fire hazard... fyi I use a2 amp charger from Wal-Mart and I do not notice my device really heating up...

Agreed. The worst I got was a cheap replacement off a street without a packaging for a dollar. When I plugged it in for a few minutes the battery turned extremely hit and the battery expanded as if it was a puffer fish that took an electric shock

LOL.........mine was a supposed "genuine" DELL replacement battery I got on EB from HK. On the first charge (in the bedroom) heard a strange hissing then a loud "pop". Some of the underside casing was actually melted and there was battery gunge all over the internals!

A lot of things I bought from Hong Kong off Ebay actually came from mainland China pfff.....
It's those low quality defects they send you. Mass market goods in china doesn't require quality passes unlike Hong Kong where it's illegal once they get pass customs.

OK, electronics 101, chargers DO NOT PUSH power to a a battery, 2 AMPS is the chargers MAXIMUM OUTPUT, the device plugged to the charger PULLS what it wants (up to a maximum of 2A of current) so it can charge in a reasonable amount of time, you may be able to charge your tablet with a lower output charger but all it would do is take longer to charge (if the charger even had the power output greater then the static draw of the device), which is why most tablets simply CANNOT be charged by the USB 2.0 port on a computer or other small .5 A output chargers. You may very well charge while generating less heat, because of the slower charge cycle using the .7A S2 charger, but at the same time if you try to use the tablet while it's charging on the smaller charger it may very well drop in battery percentage as the smaller charger may not be enough to maintain the current requirements to charge the battery and run the device.
So in short, would charging with the smaller charger harm the battery, NO, but if it is enough to actually charge the device it will take atleast DOUBLE the amount of time to recharge as it would with the regular 2A charger.

Find a fast charger, any recommended?

Stock from HTC direct (Digital River) works well.
I own the Aukey Quick Charger, which also works pretty well with the M9:

I use the samsung fast charger from the note 4 or s6 and use the motorola brick from the nexus 6. I recommend the nexus 6 brick.
I will receive my techmatte quick car charger and keedox quick wall charger tonight, will let you know

That's the same one I use in my office. Works well.
I use the charger from my old Droid Turbo at home.

I just got one of those too, and it's great. Wish it wasn't so big, but it does the job.
I just picked up a couple of Anker dual-USB wall chargers. They have higher amperage (2.4A) than most standard chargers and on both USB ports simultaneously (many dual-USB chargers lower the output when both ports are in use). Between the better charging times, the dual ports and the build quality, I'm very satisfied.
The Anker charger with Qualcomm Quick Charge tech looks even better, but I don't have any experience with it personally.
Show me the link and experience, thanks!

i have the htc rapid charger 2.0 and the aukey rapid charger (+the 10000mah external battery quick charge)
both work really well. if i knew about the aukey. i woulda originally gone for that first
Quick review of the Keedox Quick charger 2.0:
Well it has the official logo of Qualcomm Quick charger 2.0 printed on it but I kinda find it as slow as the stock charger from hTC :crying:
Tested from 45% to 100%
Till 80% it's amazingly fast with 20% every 10min but once over 80% it's slowing down, from 90% to 100% it's extremely slow like 1% every 5 mins
It took 75 mins to charge these 65% while it's supposed to charge from 10% to 100% in an hour (80%)
So we are pretty far from the advertised +70% faster charger.
Take in consideration that I am using Viperom 2.2 for the time being based on 1.40, these Roms are known to have bugs with charging time, so I am waiting for the upcoming Leedroid based on OTA 1.40 Rom to be sure this charger is crap and give a negative review on Amazon.
I am still waiting for my TechMatte car quick charger, my sis still didn't finish to empty her 2 suitcases, girls...
I don't think it's a matter of cable, I am using the same USB 2.0 cable that I used back with the Quick charger of the S6 on the S6, it was charging the S6 from 20 to 100% in 50 mins.

The Aukey quick charger I have does the same type of throttling thing once it gets around that 85% mark. I haven't paid enough attention to my Droid Turbo charger to see if it does the same thing. I figured it was just a safety feature of the Aukey charger.

So these are quick charger only from 0 to 85% !! The S6 stock charger on S6 was also slowing down at 85% but it wasn't that slow, the results were certainly faster.
Again I can't give a definitive conclusion about the Keedox before I try a stable rom based on the official latest OTA

The slowdown at ~80% full is the expected behavior to be easy on the battery. I find the quick charge most valuable when I am about to leave home and I can use the last remaining minutes to cram some juice into the battery. Main charging happens overnight for me without any need to hurry.
The slowdown >90% is behavior I have seen on every phone I have ever owned. It is a safety feature to avoid overcharging the battery. Overcharged li-ion batteries have been known to explode and catch fire, after all.
It may simply be that HTC is more conservative with its batteries than Samsung is.

Hmm ...
Now this makes sense ... Now I get why my charger works lil slower above 85% ...
Updated Viper Rom to 2.3, the Keedox charged my M9 from 34% to 94% in a matter of 35 mins
Thanks!
It looks like the htc m9 is slow with quick charger 2.0 anyway, gsmarena posted a 2h charging time for 0 to 100%.
So my Keedox is not bad after all
