Why does the phone need the battery to turn on when plugged into the charger?
I seem to remember one of my earlier HTC phones could do this. Or is my mind playing tricks on me?
No Android phone I know allows you to power it up from the charger alone. Nexus1 is no different.

Galaxy 551 lets you power up without battery.

Bump please?? or a link to answer would be nice, thanks.
I just thought i would try this as im going on a bus trip at the weekend and my phone doesn't tend to have very good battery life but i just noticed if you have a USB OTG cable and plug your phone into it with it's standard USB cable you can charge your phone via USB with your Nexus 7
Probably a bit of pointless information but i thought i would just point it out incase anyone else was wondering this like i was
Interesting, but then you have to charge your nexus because you just drained its battery. You can also charge your phone using the nexus charger without any damage to your phone.
He said that he is on a bus trip! Kind of difficult to find a plug on a bus...

Um no it isnt, I'm sure they have at least one dc power outlet/cigarette lighter.

This is good stuff... your phone is your main communication anyway (calls , texts , 3G/4G) .... you're on a long trip ... you got your Nexii with you but may not use it till you hit some reliable WiFi... why not use it as a booster battery till you get where you're going?? Handy little bit of info to have in a pinch for sure
That would be really cool if you could. The N7 has a 3900 MAH battery, right? If it does, it would be enough to charge a phone 2-3 times.

nah its only about 3300 or something, still should be enough for around 2 charges.

I'm pretty sure the nexus 7 contains a 4325 mAh battery...where are you getting your information from?

Buses with lighter sockets?
Hard enough to find a train with power here in the UK.
Nice tip for those in desperate circumstances.

What?
Anyway, how do you calculate how man times you can charge your phone? 4000/2000=2 lol? Don't need to calculate there're still to many other stuff to think about.
Just trying it to say how many times you can charge.
But this is really useful info. Thank you!

Found this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170961366135
I am planning to buy this as its costlier to go for each one seperately and also I have no time making one of my own.
One more reason to add is that the seller is the only one who ships to India.

Be careful. It looks like this auction is only for the cover, even though the touchstone charging unit is shown in some of the pictures.
As for wireless charging: 450mA limit kills it for me.
This seems more convincing:

Is there any model which will work with a case?
specifically

1A ! it will take double the time to charge than with the 2A stock charger ! no need for it !

This is the first I've heard of a limit. Where did you read or find out about that? I've seen wireless charging units that are 1A.
If you're rooted, type the following in terminal while charging and divide that number by 10. This will give you the mah.
Code:
cat /sys/class/power_supply/battery/batt_current_adc

anyone test these with a case on? Does it charge?

Just got the same kit yesterday (different seller though).
Charges at +/- 500Ma which is plenty in my opinion as I tend to charge while I'm working.
Does NOT work with any case I have, even the Rearth Slim but again, not a dealbreaker for me.
.... I have to return some videotapes....

Wireless charging is inefficient. Expect about 300-700mah charging and 600-700mah is optimistic. With a case on expect charging to be on the lower end.

The stock spare battery recharger you can buy from Samsung only recharges at 450 at it seems to recharge my batteries pretty quickly.

my phone just died .. JUST!
in the morning after the alarm belled, my phone can't be charge.
I used my cable or charger, none is working.
I think that it is my hardware problem ? ..
ANYONE HELP !!?!?
If the phone's on, reboot and try again. Or shut it down. Take the battery out. Leave it like that for 5 seconds. Try charging again.

Hello,
One probable reason is that battery totally lost energy..use a universal charger to charge the battery for at least 30 min..try re-inserting battery to phone then..and charge via x8 charger

may be its because your battery life has exhausted and you have to replace the battery
or
your micro usb port on the phone may be damaged
or
the phone may be charging but the led light is just not blinking,simply leave the charger connected to the phone and switch on the power just like you do to charge any phone and wait for half an hour or so. try rebooting your phone.is the phone charged now?
Just try and unbricked ur phone.I know it's a battery problem but just try unbricking it.Make sure to make a backup before doing anything else.

Even with the 1000mhz bug, the battery wont drain when charging even from the lower powered usb port
You could try and use another battery for a while and see what happens. If that diesn't help i think you should go back to stock and see what happens.
If these answers don't help, then i guess that your charging port is broken and you probably should unroot the device so you can use the waranty...
I went to a samsung centre and bought a new battery and a new charger and it is working fine right now thanks for your answers people .
