[Q] Charger output to low while using GPS via BT?

Hi all,
Just wondering if this is normal or if I need to check something:
When I use the Google navigation while the mini pro (on 2.1) is connected via BT to my car radio and I listen to music also from the mini via BT, the charger I'm using in my car is not able to charge the mini. After app. 30 min I can clearly see that the battery is getting low instead of getting charged. Am I expecting to much from my mini or do i need to check something here?
br
Schronk
....am I the only one experiencing this?
i've had a similar situation with my gf's x10 while being charged and wifi tethering the battery level would drop instead of rise. in order to stop this i forced the cpu to stay at 245mhz and it fixed this issue. i'm sure you could do the same with the mini. you would have to be rooted and get one of the many apps that let you control your cpu clock speed.
Thanks...I'll try an check next time...

[Q] My SGSII heat up alot

Hi all,
My SGSII heat up alot while charging. (for exactly i charge when phone have only 8%). The heat is not normal. It's more heat than while playing game.
And also it got high temp while using wifi and internet browsing between these days. Do you guys face the same problem?
SGSII is really great . But it heat up alot while playing game and turn on wifi.
Mine is a bit warm in the battery area when I begin charging the phone. But I wouldn't call it "extremely hot".
Another case is when I browse the web (that has flash) it feels a bit warm near the camera area (should be the CPU). Have not played games though.
There has been a discussion going on about that. It seems that some apps (eg Robo Defense) are not properly coded for the dual core. In addition some members also hinted, that the kernel is not yet optimized to compensate for that. The whole discussion started after a guy has "fried" his SG2 (beyond repair) while playing a game and charging at the same time. The phone still worked on AC power but no longer and battery and was unable to charge battery.
My recommendation would be,
- not to play games to long to heat up the device to much before new firmware is out.
- ...or use cet CPU to downthrottle to 500-800 MHZ
If the device heats up while charging I would try rebooting it (to get rid of processes which may still are open) or preferably charging while switched off

Which firmware are you using? I was on KF2, and experienced the phone heating up while playing games.
Updated to KF3 (stock, using Kies) rooted and all was well again. Even with excessive gaming, constant wifi on etc the phone just gets mildly warm.
There's no need to underclock etc. The heating issues just went away with KF3. If that firmware is not yet available in your area on Kies, then just put a newer custom ROM (Darky/Lite'ning/Villian etc) and try it out.
I remember whatsapping with some friends and I noticed my pocket felt really really hot. I checked and saw Whatsapp crashed. Also my battery sucked up about 30%. The phone was too hot to touch. I instantly took out the battery too let it cool down.
I never had that since. I expect it's resolved too, because I have KG1 now.
my firmware is KF2. now i decided to upgrade to KG1. is it stable now? any recommend rom?
As long as it stays below 50°C it is perfectly NORMAL.
And besides there is NO heat up issues with this phone.
Regards.
Hello
My s2 heated up alot too
so much so that it melted my simcard whilst it was on charge
also got led burn marks,
sent it to samsung lets see what they do 4 me
I already upgraded to XXKG1 and still heat up alot while playing pottery game.
This is why from the factory apple underclock their cpu's.
Samsung got the crazy idea of overclocking an already power hungry cpu.
A phone that gets too hot to touch under normal use is not fit for purpose

[Q] Battery Life and playing large files

I've been watching my battery life recently as I hate my phone dying during the middle of the day and was wondering if battery life would be affected by playing large music files?
I listen to spotify quite a bit and haven't really noticed my battery severely affected by playing music for a long time but this week I was listening to a podcast which was 160MB (2Hr music podcast if you were wondering) and my battery life plummeted. This would also correlate then to why my battery life plummets when listening to other large podcasts.
Any ideas
Try to wipe battery stats from recovery or calibrate your battery with an app from the play store.Also if that podcast is on the internet or radio i think that's why (those signals like to eat battery) .If not then try switching to 2G only mode when you are listening to them and turn off background data.

wiping batterystats has been shown to do absolutely nothing. Battery calibration apps are also useless. If u were streaming this podcast vs listenjng to music locally, thay would explain the large drain.
I had all internets (wifi and data) off to try and max it out yet it was still plummeting but my CompSci friends have said that it's likely. Thanks for your help guys
