i bought a power block a few months ago, and while i don't use the powerblock, i do use the provided usb cable to charge my phone while i'm using gps in my car. sometimes my phone will get really hot, and stop charging and other times it won't. there's no variables between the two instances.
a little bit more information, the usb cable provided with the phone doesn't over heat the phone, but also doesn't charge it fast enough to keep the phone charged while using gps(doesn't even slow the discharge). and the usb cable from the power block didn't either, until the MM update. i haven't tried a car charger since the MM update. and sometimes i can do gps and google play music at the same time without it overheating and other times just the gps will overheat
Get a 2.1 amp Power Adaptor. Get a decent brand name like a Griffin or Belkin.
Does it get hot around the power button?

I had a BIG problem with a third party battery charger (RIMAX).
It is a Car charger and a wall mount charger, with USB plug and cable, but IT WORKS ONLY WHEN THE WIZARD IS ON! If the battery goes down for some reason and the phone couldn't turn on, you're lost! :evil:
So, the lesson learned is: before travelling without your original charger check if the one you have could charge the wizard also when is OFF and not only in stand-by mode!
I also have a strange issue with a third party car charger - after plugging in the car charger I have to switch the universal off then on again to make it charge...very wierd!
I've also got one of those, though would prefere one with a bit of cable in the middle to reduce stress on the connector.
Have you checked the amp output on the chargers. They're probably putting out 0.5 amps (USB spec). If you look at the wall charger that came with the wizard, it puts out 1.0 amps. That's why when your battery is completely dead, the 0.5 amp charger can't put enough juice into it to get the battery up to a high enough level.
Actually, according to the USB spec, a device is not supposed to consume more than 100mA without being recognized by the USB host. That is, the USB host is only going to give your phone 100mA until the phone says, "hey, i'd like 500mA, please!"
Sometimes manufacturers may shortcut this and just allow the port 500mA at all times, but a standards-conforming one won't.
This MAY be part of the reason why we have problems charging a completely dead Wizard -- it's only going to get 100mA until the device has enough juice to wake up and request more.

Ah! - That's the problem I had yesterday - had left my Vario on with TomTom draining away the battery and forgotten about it on Saturday night, had just spent the day moving house and everything was in chaos and had no idea where the charger was.
So when I realised it was dead on Sunday whilst out in the car, I plugged it into the car charger that came with my GPS unit, which I have used to charge the phone many times before - but it would not charge, no light, nothing!
When I got home all I could find was the mains charger for the GPS and a USB cable - tried both and none would put any charge into the phone.
By this stage I was shi**ing myself that the phone, which I got mainly for GPS for travelling around Germany in June, was DEAD - with 3 weeks to go!
of course later in the day, once I had eventually found the proper charger, it took a slight pause after being plugged in and then the little orange light of joy came on and brought me salvation!!!!!
I suspected it might have been something like the previous poster said but not being very technical I really didn't know!!
Thanks.
I've had the same frustrating experience. When the battery is very low or dead the only charger that will work is the original adapter, not the car charger or cradle or pass thru my laptop. As I result I have to carry the original adapter whenever I travel and I often wake up with a dead Wizard if I dont realize how low the battery is when I park it in the cradle.
Very frustrating. I dont understand why Boxwave doesnt use a beefier adapter connected to the cradle.

when using my phone in the car, i have the phone stream bluetooth to the cars stereo for audio, and navigation, i used the headunits built in usb to charge the phone wilst doing this, and noticed that at the end of a 4 hour journey, the batter had drained from 98% to 23%. So i bought a samsung in car charger and spent hours installing it with now wires around the front (im very perticular about this) and im still on a negative charge. Im running cognition s2 v1.31, and using poweramp for audio (only one that seems to work with a2dp) and copilot/google maps for navigation. When i run these programs, if i hit task manager it says there only using around 14% cpu each, so why on earth would it be getting a negative charge?
How about if you try and use none or maybe just one function of phone whilst on charge cable and see how battery performs.
Next check I would is to use charger in another car and see if the problem is in the hole in the car where you put the charger.

Is the display on all the time? That's usually what drains the most battery when combined with navigation.
This phone consumes too much power for running and charging in your case. Ordinary USB chargers use to provide no more than 500mA. It's not enough. You need much more. Just to try something more powerful - like iPhone 4 usb car charger. Probably it will solve your problem.
Well, ive gone and bought a charger rated at 1000ma, and it doesnt loose as much yet its still a negative charge, he screen is on consantly. After more heavy testing, using pwer amp only streaming audio was fine, it charged pretty quick, using google maps only, it charged, not as quick but it did, same with copilot, what annoys me is i came from an iphone 4, and was able to use tomtom as well as streaming bluetooth and it used o charge pretty quick, and never get nearly as warm, im so contemplating selling the sgs2 nd going back to iphone
Its already been documented. This phone pulls more power than the charger supplies. This is limited in the kernel so nothing you can do other than not use the phone that hard.
My GT-i9300 seems to only recharge when plugged into a mains charger.
Until recently all was fine, afaik no updates... then
I travel alot, and use a car charger to maintain battery... it just stopped working, first thoughts were the cable..;. but I have 2 phones and the cables work with the other phone (bought new ones anyway.. just in case.. you can never have to many cables).
at home we have (amongst other things) a 2amp multi usb hub, it has little lights to show which socket is active, when the phone is connected the phone does not charge and the hub does not register the connection.
.. so I'm thinking the phone microusb is faulty... I carefully wiggle it to see if it connects... but get nothing.
however, the samsung microusb charger that came with the phone does still charge the phone.
My feelings are that my phone has suddenly become fussy about what charges it..
I've done a search and found mention of Googy max kernel for the charge control feature
however before I do this please, any tips, suggestion WHY this might have suddenly happened? and any alternative remedies. Thanks
btw: using Carbon-kk-nightly-20140302-0518 with no problems previous to this... except a dialler issue.
I've got a strange issue. When charging with my stock AC adapter, it charges about 40%/hr (according to Gsam). If I try a 2A charger I can get over 60%/hr. I have three car chargers, I notice each one charges at more like 5-10%/hr. When using Navigation with the screen off, I discharge at around 20%/hr. With the screen on, it jumps to 40-60%/hr.
All my car chargers came with the data pins shorted. When I plug in, it says "Charging (AC)". I don't think my car is the issue because my friend tried charging his Iphone with my charger and it didn't seem to work, but when he pulled out his, it charged much faster.
I remember that in the past, I was able to use the Nav while with my car charger and it would last all day on long road trips. With the charger in and running Nav, I might go up some small amount, like 1%/hr. Now, with the car charger in, I'm still losing and lucky if I get more than an hour or so.
The only conclusion I can think of is that recent versions of Nav or something with CM11 is drawing much more power. Although I've had this issue for at least the past year
Hi,
So I've got a brand new phone very recently: less than 7days ago.:
I'm overall very satisfied, the battery holds charge for 3 days of normal use etc, but I'm having an issue with the charging;
I'm using Oukitel's OEM Cable and wall adapter and get approx 25% with 8-9h of charging. It's worth noting that the "flash charge" worked the first time, getting me from 30% all the way up to 60 in maybe 2h (supposed to be a ........9V2A/12V 1.5A charger), I then unplugged it to get to work. Data pins do work well, I'm able to transfer files and the phone recognises if it's plugged over AC or USB. I'm having the exact same speeds as my 5V 2.3A wall adapter, so i'm thinking the flash charging doesnt work at all anymore.
I have factory reset the phone 3 times now and unplugged the wall adapter for exended period of times to empty capacitors.
I'm really out of ideas and don't really want to send it back because of the cost and time (almost took a month to get there!)
I've sent a message to the support a couple days ago but no answer yet, I think it's hopeless. Anyone having better ideas than me?
I'd really appreciate ANY feedback, even if 20% get me through the day easily.
Thanks for your time.
PS: The phone doesnt heat up AT ALL while "charging" with any of my adapters, including OEM, and i'm having no other type C cable to test with.
I guess the Charger's data pins could be the issue, I have taped data pins of my usb cord and the phone thinks it's charging over AC everywhere, I don't know what to do to verify this though.
(edit) By touching the USB cord, i've noticed window's disconnect sound, I think the cable could be not stable enough and "disconnect/reconnect" with the charger often enough that the flash charge doesnt kick in, I'll try different positions tonight and keep this updated.

That was the cable, bought a fast charge adapter and cable and it now works. Using new cable on old charger works. To anyone having the same issue, just buy a new cable. z
