i was charging BB passport first time. I shut off it completely and started charging... after around 1 hour, steel metal around mobile was heated up to some extent and also back cover also warm...has anybody seen this issue?
What can be done next?

Were you using the charger that came with your device?
Sometimes if the amperage on the Adapter is not adequate it can generate heat.

Used adapter is from BB playbook, i thought it should be compatible to passport....
Heat is normal, we're you using device during charge? Felt some heat from device during hard use, nothing my iPhone 5s didn't do

phone was not used during it was charging...it was completely shut off.
This is your problem. You're using a charger that provides higher amps that was designed to charge a tablet. The higher the amps, the more heat it will generate. Either use the charger that came with the device or deal with the heat; but there is no issue.

Ya, it makes sense.
thanks, i will check passport/playbook adapter spec and experiment with passport adapter next time.
The steel band is fulfilling a good secondary role as a heatsink. Hopefully this reduces battery degradation. It would be an interesting experiment to see whether a temperature increase in the antenna affects signal reception and quality.

Yeah it's the 1.3A vs 1.8A
Now I'm curious, has anyone experimented with any higher amperage?

That can be very scary and I would have called 911. were you frightened?
I'm now thinking twice about my future BB PP. to Be or not to Be.... that is the question.
Thanks for the warning just the same.
You're joking.. right? Lmfao

So... if both my phone and my laptop are made by Sony, why is my phone getting hot when I use my laptop charger to charge it?
This shouldn't cause a problem... right... right!?
Sorry! I couldn't resist.
In all honesty, though, chargers and batteries vary from device to device, and while using them across devices may be a common practice, it isn't necessarily a smart one. You risk damaging your battery, etc. when you do this. Try to only use the official charger in the future!

I charged my z10 with my PlayBook charger for a year and half and never had any issues except for heat. I do not believe the higher amperage degrade or damage the battery, it just charges faster. I charge my passport with PlayBook charger too

What did the onboard battery temperature gauge say the temperature was at? I get up to 40C pretty often with charging or usage in bad coverage areas. The device feels hot but it is nothing to worry about.

totally not true. If the charger is rated for 1.8A and the phone needs 1.3A it will draw 1.3A. The circuitry inside the phone is designed to (likely) coulomb count for battery charging and will limit the charging current so as to not damage the battery.
If you used a charger rated for 0.5A the phone would take forever to charge and you could potentially damage the charger.

I know with BBRY phones (not sure on other manufacturers), if your charger is too low ampage you get a message pop up that the charger "won't charge the phone".

My Samsung Galaxy S3 will just charge slower, they didn't put the effort into detecting too low of a charge rate. If BBRY did that it's a good thing! good to know
The higher amperage won't damage the battery, but the higher temperature will. Your phone will only allow a charge at its maximum charge rate regardless of the charger, but the max charge rate is not good for batteries due to the excessive heat. If your Passport is brand new charge it with the Passport charger and only use the Playbook charger if you need a fast charge and your in a rush. Try and stick with a slower charger for overnight charging. The cooler temperature will help the battery life over time. Good luck.

Yeah I've noticed that on my Z10, it was a major issue and caused worse battery life in the long term.
However, all of the newer phones can take amperage up to at least 2A. As you said though, if it gets more than its made to then it just ignores that charge and it heads back to the wall. The devices are smart enough to only take however much they're able to.

Very informative thread!
I actually got a charge outta some of the replies.
However, a few of the replies kinda shocked me, sorta.
Then you must have flunked your classes. lol
The phones might limit current but it is more of protection to prevent overloading if say you plugged it in with several amps. It will either charge, or it won't. It won't limit to a specific value. This is why you can use a computer USB port to charge at 500mAh(nominal current output of most computer USB ports) , a USB charger at around 700mAh, a medium current charger at 1400mAh, and a high current 1800mAh.
And depending on the current, the phone will charge slower or faster.

the charging circuitry will have a current limit to protect the device yes, however the phone will also try and charge as fast as possible using a combination of coulomb counting, temperature and time algorithms. The charging rate will slow (or stop) if the temp gets to high to protect the battery.
Charging from a PC USB port will limit to 500mA as this is the max the port can provide, if you try and draw more the PC will shut the port off to protect it.
The device knows what it's connected to so in the case of USB it knows the limit is 500mA
if the chargers are dumb they will have internal current limits so the phone can only draw so much from them.
It depends on how they designed the circuitry for charging the battery.
at ay rate the addition heat felt by the OP is due to the additional current the phone is using to charge.
It should be fine after a day. The CPU is just working overtime updating and syncing. The metal frame is also the heatsink for the Passport. The motherboard is located to the right side.
It will also get warm when charging and using it at the same time. When using graphic intensive apps and games, it will also get warm.
I use a high current Playbook charger and all is well. Just tiny bit warm when charging.
I use my playbook chargers (have 5 of them) to charge Q10, 9900, S4, 2 playbooks and a Passport and have had no issues whatsoever except one charger died after 3 years of use

I was also using always my PlayBook charger to charge my 9850, Z10 and Z30. Never had any issues with it, I use it now for the Passport as well.
