When using phone heavily and charging battery drians.

Hey guys thought I would post here has anyone else expierence this before?
When charging in my car and using either gmaps with gps and listening to music with my g2 the battery drians even while charging!
Yesterday it screwed me over. I was going to a place I had never been and no matter what I tried it wouldn't boot any more. Even after plugging it in to the car charger.
The farthest I would get is that it boots into recovery I hit reboot now and it endlessly loops. Its weird. Is my battery bad?
Thanks!

Your battery is fine. I suggest you pull the battery out for a minute or 2 and put it back in
BUT
do not turn the phone on yet. let it charge for half and hour to an hour to give it some charge back and see what happens from there.

Pretty much agree with the above. Make sure you use the wall charger, not USB or the car charger, as those supply lower voltage (EDIT: current or mA, thats the term/units I should have said, per below). Let the phone charge for a long time, maybe overnight, and see what happens.
I've never tried using GPS and playing music at the same time (at least not for any significant length of time). What do you have your screen brightness set at? Since the screen is always on when using Maps/Navigation, turning it down may have a big impact on battery drain, and might result in the charging rate being greater than the drain rate.

I bought the official HTC car usb adaptor for this very reason. Most car adaptors only output between about 300 to 500mA which is less than the battery drain when you play music, use gps and have 3g activated. The HTC adaptor outputs 1000mA and is the fastest car charger I have found. It is as fast as the Nokia N86 home charger I have. Buy one and you won't be dissapointed. It comes with a coiled usb lead in the pack but I use mine with the retractable usb lead that came with my powertraveller.

USB supplies only 500mA and car chargers often only supply 1000mA as mentioned. This might not be enough to cover everything =/
My car charger (the official HTC Nexus One car dock) does 2000mA though so it's great =)

Great info. I didn't realize the HTC car charger was that much better than others.

Ah ok this has to be it! Yes I imagine between taxing the cpu, generating heat, 3g, gps, and the screen on with music playing would drain faster than a regular usb can keep up with! Thanks guys. I will be finding a better car adapter! Anyone have any links of where they went?

I purchased the Motorola Car Charger from the thread below. Did some research on it, and it is rated to put out 950mah. Not quite as much as the stock HTC car charger, but its only $5 if you follow the link from the thread.

I don't use my phone nearly as heavily as you do in the car, only for GPS directions when I need them. But it works great when I need a quick charge. Drove to work last night (about 15 minutes) and it took me from 22% - 34%. Enough to make it through the evening shift!

Samsung Galaxy S2 very hot GPS + charging

Hi guys,
I used GPS for first time with my new SGS2. I was surprised how phone was hot. I had SGS but I never had any problem. GPS program is Sygic, I used same car charger, which I used for SGS. I drove home maybe 10min and phone was realy very hot, the screen also,back of the phone. Do you have same problem or do you think my phone is faulty?

Mine after 30 min surfing the internet is very hot (next to the camera and screen on top). Also i am worried about that...

Yes this I have same, but it is still OK compare to GPS and charging.

GPS + charge is always a hit or miss. My SGS was a little better, but my HTC Touch Pro 2 got blazing hot. All depends on the device, I'm more worried about the long term effects of such temperatures to the camera, which is in very close proximity.

I noticed when using sygic with gps that the battery continues to drain even when using the car charger.

There's a good answer to that. I had a cheap generic USB car charger and noticed it drained quicker than it charged. The reason is down to a pin on the USB connector. Your phone will only charge at rate it would if plugged to a PC. Buy a genuine Samsung car charger (about a tenner) and it uses fast/full charge. I think they remove/link pins which tell it how to charge. I also found it doesn't get as hot with a genuine charger

Maby I can confirm this ...
Was on a 1 hour trip using navigation.
My screen brightness was about 20%
Did not get warm and charged +6%
I use a standard Samsung charger.

True is, I have non original car charger, but I bought some cheap one. Never charge my SGS, just kept at the same level. So I am going to buy original from Samsung.

When ur using anything Radio and/or charging for a long time its gonna get hot, by hot i mean burning hot. On my sgs, nexus one, cliq when i am on long phone calls (>30min) and charging they all get hot, and get hot when using gps even when not charging. GPS on SGS is a hit or a miss though, barely use that phone for gps

Don't listen to peopel telling you it's the charge that is causing the phone to heat up.
thats just nonsense.
Its the 1.2ghz cpu.. and the close tight body of the phone.
I had the Atrix, and after 10-15 of heavy usage or just gps, the bottom portion near the sim area would be hot to the touch.
Think about it this way.
Why do laptops even in such tight close spaces have some fan going? because things get hot.
Stop the fan on a laptop and let the heatsink just do the work and it will burn u.
Its just the thep hone despensing the heat.
I personally dont' think phones with 1.2ghz processors should be made so small, and not have some time of active cooling.
Seriously even if my NAS Server with a marvell 1.2ghz CPU has some type of cooling fan!
this is just ridiculous

Mine also tends to heat up. I then always take off the case and try to get it cooled down somehow. But i've experienced it myself: half an hour gps+navigation=processor hot as hell and battery drained down from 85% to 15%...hope the latest firmware update fixes this...and btw: heat is not very good for any kind of battery. It makes them drain faster afaik!
Cheers

Well I have a 1mA charger which I used with my HTC Desire to charge it during driving and navigating. It worked well with my HTC Desire (the HTC Desire also needs a pin connection, otherwise it won't charge fast enough during navigating) but the same charger did not work very well with the SGS2. Yesterday during navigation the battery level dropped slowly... Even though I used the same charger as I used with my HTC Desire.

Hmm that's odd. I'm using the same charger I used for my sgs '1'. I have to admit not tried navigation on my sgs2 yet for a long drive. Will have to test this.

Yeah,u are right~
The competion of thickness between samsung and apple,or other android os manufucture like S.E has crushed samsung's mind.To elicit applause,the Korean giant just sacrificed the stability to make a both thin and powerful phone.
It's hard to say the choice is wise or not.But we can already find this company is becoming upset due to the pressure from the opponents.

Did Lincoln to London (135miles), phone in cradle with brightness 100%, CamerAlert and Google Navigation running, powered via USB converter in the car.
Battery went up about 1% every 20 minutes.
Phone out of cradle at the end wasn't hot to touch unlike every other phone I've had.

IT seems that samsung has a quality variation. Did you use a brand charger or an aftermarket one?

Ok guys i am quite worried now. I played game about 10min and the top half of the phone is quite hot again. Do you have same problem or should I take mine back to a shop? I do not think this is normal right?

battery drain with car usb and gps

Hi
Using today the phone @ 100% brightness with car charger connected and using Sygic / Copilot, I see that my device can't not even charge at the same time that I am using it, but maintain their % of battery. Even with the charger the phone drains battery.
WTF samsung, So i cant make a long travel without running out of battery?
Anyone more with this problem?
PS: My HD2, HD, TyTN2, etc doesn't have this problem with the same car charger, they even charge at the same time.

What's the rating on your charger? I had to swap mine out for a 1A one in order to cope with GPS use in the car. Haven't had a problem since then.
I suspect the one you're using is 750mA or even potentially 500.

I have just had the same problem. I knew i needed a higher amp charger but i thought i would give it a try. The one i used is 650mA, so that's definitely not large enough. The normal 'house' charger is 0.7A (700mA) so in theory that size or above should charge whilst the S2 is being used.

I have a 1200 mA usb adapter for car (a sony ericsson, very very slim one) and I have no issues. You need a decent amount of power for that phone so 650mA will not do, have at least 1000.
http://www.nextag.com/Sony-Ericsson-AN400-Compact-853915153/specs-html
Not sure if this is the exact model but I found it to be the best because it's slim and there is nothing sticking out of the car socket, has a lot of power and I can power any usb device with it.

Yest but probably you hava a chinese charger. The rating on it is never near the real one.

oh, I see, crappy charger, ill change then thanks guys

TomTom recently released a high speed multi charger. I replaced my old car charger with this one as I had a similar slow charge problem. Never had a problem ever since. All my weapons are always fully loaded with enough power! Expensive though!
http://www.tomtom.com/en_gb/product...-cables/high-speed-multi-charger-9UUC.001.04/

If someone is using a cheap higher-powered mains adaptor without issue, could you please post a (UK) link? Also if anyone knows of a cheaper alternative to the £20 car charger that would be great too!

I had same problem.I bought Samsung charger and no problem after

2.1 Amp TomTom charger is way too much for this device. Samsung wall charger is only rated at 750mA, but someone even found out that in source level Samsung has limited the power current at only 650mA.
With 1 Amp (1000mA) top quality car charger, the phone lost charge while using Navigation on full brightness.
Very slow charging in general for this phone.

When you have the car charger plugged into the phone go into Settings/About phone/Status & look at "Battery status"; it should tell you if the phone thinks it's plugged into a USB port (in which case the phone will draw only 450 mA) or an AC charger (from which the phone will draw 650 mA). These limits are built into the Samsung ROM, presumably to keep the phone cool and/or extend the battery's lifespan. They could be overridden (especially the AC charger current limit) in a custom ROM.
Absent a custom ROM, if the Status display says you're connected to a USB port, you could try a different charger, or connecting USB pins 2 & 3 (the two center pins on the USB A connector) together. That's how the phone decides if it's connected to a USB port or AC charger -- the low-resistance (less than 200 ohm) connection between the two USB data pins is the key. The spec calls for 200 ohms resistance between the data pins, but some of the low-end high current chargers I've seen just have a direct short.
If that doesn't work, or if the Status display says you're charging off AC, then try some of the other battery-life tricks documented here in the forums; they should reduce the device's draw from the battery, allowing the charger to do its job.

Wow, this is kind of disappointing i have to say. I have noticed the USB charging is incredibly slow. You can't ever rely on it, i think it would take close to 5 hrs to fully charge from USB, that's insane! By mains it's somewhere between 2 and 3, but that's still way too high.
I take it if you buy a higher-powered mains adaptor (not one for the car) then we'd definitely get the benefits of a faster charge? Can someone post a link to one they are using and know works faster that the stock one?
Cheers

I ll try ur tricks guyz.
for the time being this is my situation (and it sux):
-car charger 1A 5v
-slow chargin and hot device
-using navigator equals : phone burns, drains battery and in the worst scenario freezes
yesterday I received a call while phone plugged into car charger with navigator session. wot happened is phone freezed (screen didnt switch off) and I saw PROXIMITY SENSOR WAS RED!

The first post got me worried for a while, but this info has put me back to ease. Pre-ordered the GS2 (India) and getting the original Samsung charger along as a freebie.

Yeah, i have simelar experience with the samsung s2 in my car.
Its eating the battery even when its plugged in and i think i have a good charger..
I found 1 solution.. I use now copilot, you can set different setting to disable the screen automatically when you drive a straigt forward for some kilometres, only when you need to turn it comes up again.
thats how i set it and it loads a little, but bad anyway.
Maybe thats what the + means in Super Amoled + (+batteryusage)

nexus S didnt have such a problems. it's only around how samsung managed chipset.
I ll try to set cpu downclock while temperature goes over 40..

(problem) drains battery while charging and using certain programs at the same time!

Sorry if this has been asked before but I could not find anything!
I have problems with charging while using copilot and spotify!
I have a 1A car charger but it still drains the battery!
Also I have noticed that using the hdmi while playing games or watching movies with the original charger also drains battery instead of charging!
Does anyone know a solution to this, or am I the only one with this problem?

I had this problem with my old Nexus One and a 0,5A car charger, but after this experience I bought an original HTC 1A car charger together with my SGSII and I can run navigation (Sygic) and even listen to music at the same time with no problems and the battery is still charging.
My suggestion try a different charger.

Its been covered in many threads, just search. The battery driver limits charge current to 650 mA in sourcce code, and the device can easily pull more than 650 mA doing many things like navigation or browsing etc.
So there's nothing you can do except someone compiling a new kernel with charge current raised.

I have lately experience on this issue.
I wanted a full day working device at my holidays, so I bought this battery pack from amazon: TeckNet Dual-Port iEP380 5000mAh 1.5Amp Output Universal USB Battery Pack (you may search it at amazon)
I thought that 5000mah capacity with 1A output is pretty enough!
Guess what: just browsing on internet (wifi) the phone's battery still drains while charging it from 1A USB port !! (using 1m long cable usb to microusb).
The phone must be in standby in order to charge it. ! UNBELIEVABLE !
Have anyone else experienced same issues with an external battery pack?

Any updates on this? Can it be fixed, or is there a reason why samsung has capped it to 750 mah?
I really hope it's not because of overheating or something like that!?

Nice phone, love the screen size and quality, but it seems it needs a plutonium rather than a Li-Ion battery.

Pretty much the same with mine but I was using Papago X5 on the go

Got SONY ERICSSON AN400 from ebay and my phone now charges with sygic running.
I was using samsung charger earlier and battery was draining while using sat nav apps

GPS & bluetooth + charger =no charge

While traveling I was using the gps (coPilot) with my bluetooth on, (just for calls) and was getting low on battery!
So... Naturally I plugged in the charger! Guess what! Battery drained nonetheless!
Has anyone else seen this? I have the screen brightness to the lowest setting... But to no avail!
I apologize if it's been covered before, but just looking to see if anyone else had this issue and any suggestions on making that battery not run down while plugged in!
Thanks everyone! Oh, and yes I have a second battery for these occasions!

Yes. covered before and many people see this. May be worth tying a 1amp or higher charger.

Also, if the phone gets too hot, it will stop charging.

I have the same thing... Its just don't charge however it maintain the battery at whatever level it was.. This is simply fixed by getting a higher amp charger

Thanks everyone will get a higher amp charger...

Are any of you guys with problems using the Samsung Cardock , or
are those chargers "random" chargers of other phones ?

my official samsung charger that came with it has decided to pack in after a month of use, it no longer charges at the rate it used to of about 24% an hour and im lucky to get about 5% an hour now. I've tried my old hd2 charger (same 5v 1a output) and it charges without any issues
samung make crap chargers

That's what I think the issue is, I'm using a generic charger and it's not pushing enough juice!

I got a 1A car charger with my mount which works ok (cheapo chinese says 1A). I think any car charger with a USB slot which says 'Ipad' would work better, IIRC the ipad needs ~2.2A so it would have plenty of juice.

I've got various car chargers, one at 850mA, one at 1A and one at 2.1A. None of them charge the Note while using sat nav (Copilot) even using night mode (dark backgrounds to maps) and dimming the backlight in between junctions. I've tried the USB lead that came with the Note and a lead from another phone. No improvement.
The phone shows Charging AC because I have the central pins shorted on the chargers, but even that is not enough. I'm thinking the only solution is to buy a proper Samsung charger, which might have some other trick up its sleeve for getting the Note to draw sufficient current.

I have just switched from using co pilot to another satnav app and the phone now charges faster. I knew co pilot was juice hungry. ...
