How to charge battery without phone? - G2 and Desire Z Q&A, Help & Troubleshooting

Hi,
Does anyone know how I can charge the battery without the phone?
I tried to connect a USB cable (red & black wires) tot the + and - of the battery (correct polarity, I checked on the internet).
But that doesn't make sense, battery isn't charged after several hours.
Does any1 know how I can do this?
Thx very much!

Why not just get a charger from eBay or Amazon? Doing it your way, even if it sort of works, may do serious damage to the battery. And the last thing you want to do its smoke a lithium ion battery.

not sure if it safe/possible to it any other way then in the phone or a charger ment for it. there are universal ones and ones specific to the g2/dz that charge the batter without the phone. if you were do get it charging another way you may overcharge it, granted I believe the oem batteries should have a function to stop the charge @ a certain point but why taje the chance?

If you can afford to check on amazom.com. I bought an universal external wall charger from them and it came with 2 batteries as well.

Thx 4 your help.
I will explain why I'm asking this question:
the USB port of my Desire Z is broken.
I have ordered a completely new motherboard to fix this issue.
The board will be send to my homecountry from Hong Kong.
They will send it this week.
Until then, I have no Desire Z because the battery is empty and I can't charge anymore...

I can't remember the brand, but over at Staples there are these 7$ USB adapters for just bout any kind of battery , you just move the prongs to the contacts on the battery and slip it into a USB port (but given how our batteries have the contacts on the bottom instead of on the wide surface that may be difficult).
But yea I would say using an actual charger would be your best bet.

Where did you order your motherboard from?

Battery workaround

Hey
I really want this phone but the fact it has no removable battery is a massive minus.
Has anyone discovered a work around for this? I mean like a small emergency charger that will boost the phone for 1-2 hours?
When i go to football i always tweet/FB heavily. And i find by 4-5 pm (5 hours unplugged) i need to think about putting my spare battery in. It isnt the best spare battery but will give the phone an extra 1-2 hours which is enough time for me.
Thanks

Are the Duracell ones any good for phones this high spec?
Are the others small enough to carry in your pocket?

Brand/price of the charger doesn't matter. I use 10 euro worth small charger that has connector built in, it doesnt use cable. I just plug it into my phone and it will charge it. I always have it in my bag, fully charged. Use it rarely, but knowing I have it there helps. It's also light enough.
a bigger version of this:
I have one of those 5000mah packs from asolar (theres alot of them on amazon) and it works great! Although it's way too large to fit into your pocket, i usually bring it when I'm traveling. It can fully charge a phone like the one X - Twice!
About the size:
Its about the same size as an SGS, but twice as thick.
Are the duracells any good? Would the one x get a fee hours of charge?

True, but the specs do. How fast the battery pack outputs power makes a big difference in how long it takes to charge the phone. Also some of the higher-end solutions can hold up to four full charges. Here's a chart...
Yes but I wanted cheap solution that works. So it charges pretty quickly as it gets really worm while charging my phone. It's not going to make my phone last a day, the purpose is to give me a boost when needed, nothing more, and for that its perfectly spent tenner.
I do have another charger that holds way more power and is able to charge my laptop, comes with multiple plugs as well as USB port, but I wouldn't carry that with me everyday like I can with the small cheap one.
I got a 7000mah one from Amazon for 20 quid, it's a cheaper less rip off copy of the 'new trent' chargers can't remember the brand though. Works a treat, charges with 1amp just as quick as a mains charger!

looks nice, what other cables does it come with ?
Longer usb cable that connects to your phone, it also has a USB port at the top of the battery Anker so you can use different usb to charge different phones
Looks nice is it heavy;
You can carry it with you when
You need a extra charge right;

half the weight of the wildfire S. Since its very slim you can carry it in your pocket or if you are a girl, then inside your purse. Well worth my $20 IMO
I gotta get one of those... my phone barely lasts a day.. D:
so am I right in thinking you use this to charge your phone up when it's out of juice....and if so, how many times can it charge up the wfs? I'm thinking it could be useful for weekends away or camping trips etc?
Yes camping it would be great! The power bank is 3200 mah so it can charge the wildfire s 2 times from dead, they make a 8000 mah as well

a case with a built in battery, like these. AFAIK, no one makes them for anything except iphones.
those are cool but that wouldn't happen on our phone or most android phones. Its easy and cheap to make cases for iphone because the design stays the same for the most part, designers have more time to create the case and for android phones the design is always changing and people are always getting new phones so a case like that would be great but there isn't enough money to be made by the maker, the wildfire s is popular but not that popular, I could see this battery case being made for the HTC one X

Best extended battery?

I bought the Chichitec 2500mAh extended battery pack and they work very well. I get on average a minimum of 4hr screen on with lowest brightness as oppose to 2hrs and change with the stock. I also use jucedefender and I rarely talk on the phone. I would recommend them.

I have that one, it isn't bad, but it isn't great either.
Typical Chinese quality (Samsung is spelled Sanmsung and Galaxy is spelled Galyxa when you actually get it).
Battery life is, well, I dunno. It's hard to say. My phone was at 57% charge, I turned on the extended case and without any use it charged my phone back to 100% no problem but the extended battery was pretty much dead. I'm sure it works better when both the phone and extended are charged to 100%. The AC/DC converter inside the case is VERY inefficient and gets VERY hot. Don't even bother attempting to charge the extended battery while the phone is in it, I'm suspecting it will catch fire or melt lol...
I like how it has a power button and the kick stand works. The case is very sung and everything lines up properly so for build quality I give it a 10.
The USB port pass through is CHARGE ONLY, data pins are missing so it kinda sucks if you use OTG devices or need to plug it into the PC to transfer files etc. But all in all you get what you pay for.
My friend has the Hyperion 4200mah with NFC. It works excellent, double the battery life. He usually gets 3-4 days with normal use out of the phone without charging (but that depends on person to person).
Here are some of my hyperion 4200mah stats

If that's a universal charger with movable connectors, don't get that. It wont charge your battery to 100% and might mess up your connectors on your battery.

both chargers above have an extra USB port...so you can connect a USB cable from the charger to the phone while a spare battery is charging..

There is also this one from Kidigi as well.
It features dock/sync mode button, audio out via usb.
It has a bit less physical support but both Jeurum_92's suggestion and this one have a removable insert to help accommodate a case. It's also a bit more $$$.

Yes, it has an insert wich you can remove so if you have a slim case it will fit
Looks like you need to use a USB Mini cable and not the cable it's supplied with to get both to charge at the same time though.

***charging issue n7100 | experience#2 [resolved]

Hi Guys,
Got a problem here. This will be my 2nd Note2 after sending it back to Samsung couple of months ago. It was charging this morning and tonight after a long day of work, I decided to play some game on it. Noticed that the battery is on 15% I decided to charge it. After 30mins I checked the status of the battery and to my amaze it was not charging! I tried 3 different cables, 2 different chargers, and none of them works. Tried my cables and chargers to a different phones and it does work. I connected my note 2 to my laptop, and it does not recognized it. Tried to charge it while it is turned off, I can see a battery icon, but it does not show the charging battery icon. It will disappear in a few seconds. Please see image below:

It's a rooted phone. Tried to clean the charging port. I even opened it without damaging the warranty sticker, and I can definitely say that there's no moist inside. But just to be sure, I blow it using a hair dryer with the temp off. But with no luck. I used to experienced this a few weeks ago where went back charging after a few minutes. But this time it's worst, it's been an hour and a half and still it is not charging. I can't do a full wipe yet since the battery got 9% left on it.
I know that if it will really not charge, to resolve it..it's either I send it back again to Samsung, replace the board myself (hope it works), or buy an external battery charger. Unless there's more that I can do to fix it.

I did but to my amazed after leaving it alone the whole night, It went back charging again. Yes I am glad that it's working again but I am worried it might happen again sooner or later. I have read some threads with the same issue and with the same outcome, I really want to know what's behind this.
So if its under warranty unroot and monitor
