Hi, is it possible to make the phone charge whilst the screen is on?
plugged in charger at 37% battery and drove with navigation for 6 hours and when i arrived it was still 37%, would of been nice to charge it at the same time.
On return journey i kept screen off for the last hour so it would charge.
Thank you
It does charge even when the screen is on. I charge it while web browsing and it goes upto 100. You're using a navigation app which is processor extensive(as well as data) so that's why you battery neither dropped nor increased.

if it wasn't charging your phone would have been flat after an hour, instead you got six hours of satnav and some more for later.
You might find that you can get a bit more if you use a different car charger with a higher ampage, but breaking even is to be expected with SatNav.
Thanks, thats a shame as my SIi charged with navigation on.
I understand its powering the phone but not charging the battery, i use a 2amp charger same as i used for the SIi
USB car chargers are never as good as the wall chargers for charging your phone when the screen is on. I have tried 1 amp and 2 amp car chargers of different brands and like you, if my percentage is say 38% or whatever with screen on, then it will take close to an hour just to put 1% charge. Plug it into wall charger with screen on and it charges much quicker.

I've noticed that when using TeleNav / ATT Navigator, my battery doesn't charge.
I do a soft reset and stop using GPS, the battery begins to charge.
This has happened with several Roms, so this leads me to believe that it's an equipment issue. I don't know if I'm alone with this issue.
Something like this is easy to overlook. The only reason I noticed is because I had to use GPS a lot more than usual and my battery went out while it was supposed to be charging.
If you're using any type of GPS, take a look. If you're good or not, just state what you use.
Thanks.
Mine will charge when I am using Garmin or GoogleMaps.... I have noticed that if the phone gets to warm it will still discharge even if it is plugged in. Keep an eye on the temperature of your phone!
Thx

I've got my phone mounted on a spare belt clip i attached to my dashboard and ive noticed the same thing. there comes a time after it's been charging for a while when the light stops "breathing" but the battery is not fully charged. As far as GPS, i figured it wasted battery faster than it could charge, since i also have bt and the display stays on. I've been meaning to try it with an A/C charger in the car instead of the 12VDC. I'll let you know if theres any difference.
Thanks ...

I noticed the HEAT, my TILT did the same thing but it charged. The only issue I had with the TILT is when the battery is under 30%, I would have pull out the battery before it decided to charge.
*gmgonzal*
I'm using a mount also (15'' Gooseneck non-winshield). It starts out charging and then stops. I'll try with an AC adapter also just to see what happens.
There maybe something to this GPS & Charging......
**(used to keep post short)
I have the Ac charger in my car and it works wonders. If I run more than three things at once then it will stop charging. All it take is a soft reset. Then all is well. As most said keep an eye on the temp. BTW I am using Energy's 2.0 040509 build with TomTom 7.915(9196)
Thanks Max, I figured the AC Charger would be better, it always charged very quickly at home.
Noticed the same thing on a six hour car trip. I use a gooseneck windshield mount and have Garmin XT and bluetooth to the stereo all the time. After a couple hundred miles it stopped charging and the backlight goes off, making it a pain in the ass for looking at the GPS screen, any suggestions? are u using a ac adapter and than plugging in your home charger? BTW am using an old Motorola car charger from the early RZR days.

No difference if you use a 12v or a 110v charger.
The TP warms up and at a certain temperature shuts off the charging so it will not extra over heat.
I place my TP where the AC can cool it down and since then - it will charge for hours.

That's freaking hilarious. I do the same thing. I notices my Fuze would stop charging when plugged into my car charger if it got too hot, so I simply positioned it where my AC would hit it. Now I don't have that problem anymore.
I tried the AC charger in the car....same thing.
Tried Google Maps also. Basically when I use GPS, charging stops when the device got warm. My device didn't take long to get warm....about 2 minutes.
There's gotta be away around this other than placing it on the air vents. The TILT performed much better with GPS.
my results
finally got a good long run with gps on I-95 and this is what I found:
1. According to tBattery, the 110V charger and the 12VDC charger were the same as far as charge being + 100 with the gps on, so the battery would still be charged if gps is running with the screen almost full brightness, BT on and a data connection.
2. Also according to tBattery, the temperature got to above 46 degrees when I noticed the phone was no longer charging, whereas at home it rarely gets over 33 degrees. The current showed more than 300 negative under these conditions.
SO technically, once the phone stops charging due to temperature, the GPS with screen full on and all the rest tend to drain the battery. Even if the phone is plugged in to the charger. If only it would stop charging the battery but at least take power for the device from the charger, that would have been good.
So I'm going to reposition the device on my dash to where the AC vents can hit it as others have done!
I have two different chargers in my car. The one that will charge my touch pro while running GPS navigation is 5V/1A. The one, that will not charge while navigating has 5V/500mA (which is max. USB-power according to the specs).
Since TP's GPS consumes approximately 500mA (I've read that somewhere on the internet), there will not be enough power to charge. Keep an eye on this.
I went on a 1Hr trip....
AC Adapter-Got hot in about 8 minutes...stop charging, reset needed
Cig Adapter-Got hot in about 8 minutes also...stop charging, reset needed
Aimed the AC on the device...Device charged the whole trip.
Bottom line....Keep it cool!
Lithium Ion batteries in devices all do this as far as I know. I remember back when I used my Dell Axim x51v for navigation is when I found this out for the first time. It would sit in direct sunlight on my dash and quit charging within about 5 minutes of use. One time during the winter I noticed when I didn't turn my heater on that it charged for much longer. Then the light bulb went off in my brain.
Same thing went for my Q9H, Tilt, and now Fuze. A lil air from the vent helps a lot, and keeping it out of the sunlight is an even better option.
(Be nice!)
My Streak is only 3 days old and I am thrilled with it but .....
Last night I shut it off and put it on the wall charger as usual at bedtime. It had about 80% charge left and had been working fine all day.
When I got up this morning and tried to turn the phone on, it said "0% Charge" and shut itself off. I had it on my cigarette lighter/usb charger in the car on the way to work (1 hour) and it still said 0% charge. I have had it on charge from the usb on my desktop computer in the office for 1-1/2 hours now and it says 20% charge.
When the phone is shut off, what the heck could discharge the battery completely in 6 hours????? Could the charger be bad and drawing current from the battery? (Shouldn't happen - poor design if it did!)
If it is REALLY sensitive to input voltage, maybe the USB charger in my car isn't high enough to charge the Dell? (I have seen some usb devices that actually want 5.1 to 5.2 volts to charge.)
Anyway, it is slowly coming up but I need to figure out what killed it over night. Has anybody else had this happen????

Did you fully shut-down your streak, or just turn-off the screen? There is circuitry that stops the battery from charging once a full charge is reached, as over charging will ruin the battery. So the phone should be on while charging. Another thought... Will it even charge if it's not on?
P.S. the thread title does leave some room for jokes
Yes, the phone will charge while it is powered off.
Your car charger may not have the power needed. I have seen a few posts about the car chargers.
Something does not seem right. While on the wall charger it should have been at 100 percent.
Also, my phone will charge fully in 2 hours on the wall charger, not sure of the time on USB.

Getting stranger!
After two incidents where the phone SHOULD have charged over night but was dead or nearly dead in the morning, I plan to switch to a USB charger that I KNOW is good but .....
When I tried to power up the Streak this morning (after being shut off last night and left on the charger over night) it was TOTALLY dead - didn't even light up again when I plugged it back into the charger! - so I stuffed it in my pocket until I got to work.
I popped the battery out and measured it - no-load voltage showed 4.0 Volts. When I put the battery back in, the Streak booted fine and showed 100% charge! (It was not battery contacts - I cleaned them a few days ago after the no-charge incident).
It appears that there may be something in battery-backed memory that got out of whack and removing/replacing the battery cleared the error state allowing the Streak to boot. This could tie in with the apparent charging problem?
Any ideas?
Okay so I've this problem where my battery discharges while charging!
I had this problem since wednesday that time I was on stock... So I thought flashing a custom ROM now as of now i'm on SonyStyle still the same problem,
let me elaborate my problem a bit more
-To monitor how much current is discharging n charging! -498 mA while discharging n -298 mA while charging it normally
-So next thing I tried is to charge it while being switched off, most of the times it wont charge n when it'll charge it'll reach some point n starts discharging! Discharging even when its off and plugged to the charger! BIZZARE isnt it?
-Now in order to put it on chrging i've to reboot it couple of times untill battery monitor widget shows +current... N when it reaches 100 it'll begin to discharge like it'll be empty in 1nhalf hour
-ALSO I'VE TURNED OFF ANYTHING THAT SUCKS BATTERY! AND I'M NOT USING MY DEVICE WHILE CHARGING! ALSO IT DISCHARGES WHILE BEING ON CHARGER IN A switched off state.
these things i've already tried
-Flashing custom ROM
-Putting my cell on powersave CPU governor
-undervolting
-charging using USB
-CUSTOMER CARE CENTRE only resets the software
I'M SO FRUSTRATED THAT I'LL BURN THIS CELL INTO ASHES! Anybody help me before I kill thislil fellow!
You might try resetting your battery stats on clockworkmod or xrecovery. Charge until 100% and let it discharge naturally to switch off, allow a few days of charge cycling and it should be ok.
Lipoly batteries dont trickle charge. If you leave your phone on charge for 8 hours it will just switch off the charger, discharge for awhile and then switch back on the charger. Most take 1 to 1.5 hours to charge, so if you leave it plugged in you will be charging/discharging about 6 times in that period. Lipoly have a limited number of charges before they diminish, usually about 500. So if you leave it plugged in you can reduce your battery life span considerably - otherwise it should last a good year and a half before it wears out.
Dont ever try to trickle charge, overcharge or manually discharge a lipoly battery as they have a tendancy to explode.
The good news is lipoly batteries are cheap to manufacture. You should be able to pick up a decent bst-38 (or substitute) on ebay/amazon for around 15-20 euros. Dont be hoodwinked into the 2000mAh batteries, most are fake. My 970mAh can last 2 days on Gintonic rom.

I had a similar problem with the battery discharging whilst charging.
For me the problem turned out to be my USB cable becoming faulty. It would still transfer data when connected to a computer, but would get a similar problem to the one you describe when charging. Might not be the same problem for you though.
I am now experiencing this problem. I think it is my usb cable too. Will buy another 1 soon. It discharges then charges again when I pull out the cable and plug it in again.

Well already tried wiping battery stats
heres what I've discovered till now
-The charge current drops as if the battery is at 91% but it isnt even close
-It is either the battery is sending wrong data to charger, or it is faulty
-Not able to explain how n why it discharges even a switched off state???
-Only solution I can think is a charging dock for BST-38

If I leave my cell on charging for 8 hours, then after 8 hours my battery will be zero... It'll keep blinking the red light for hour or more... See thats a wicked problem...
happened to me also, had to use a better cable (don't use thin and/or long cables)
Yeah I tried with a Nokia made cable and its charging flawlessly! This is my first time with a Non-Nokia n so far the experience is not very good!
btw thanxxx a lot for your attention n concern!
- similar (identical) problem, tried similar resolutions (factory reset/sdcard/sim removing/different chargers/battery replacement)
- disassemble my phone... and found out, that micro usb connector replacement is unrealistic.
- watched charge/discharge/voltage/current/temperature process trough battery monitor widget (1 minute sampling)..
- re-calibrated battery many times
RESOLUTION : micro usb connector or connections in mobo is dead. I build charger with current meter. No matter, what says my phone about charging (pluged in - discharging)- any information displayed delays for minutes on phone. IF my external current meter says - "charging", than phone state is "CHARGING" independent from what phone is displaying at the moment. Moving usb charging connector in phone causes current to stop flying to phone or reducing current value. Phone still says "plugged in" and or "charging" on "discharging"...
Temporary resolution: little pushing/deformation on charging connector (male) and LED in charging chain, witch is displaying - charging or not. Every time connecting charger i'm looking on indicator LED and moving charge connector, till LED says "charging" and then no more any moves on phone.
Future resolution: contact-less charging trough inductive coupling
Guys I bought one Samsung Extended battery kit (2000mHa - genuine) last week and it worked a charm, noticed a considerable increase in battery life when compared to the stock battery 1650mha.
However on the weekend my Galaxy ran flat and now charging the phone, the phone starts charging, boots up, Samsung flash screen appears, then loads the main screen, stays there for 5 - 10 seconds, then phone powers down and turns off
I have tried several chargers, Blackberry (700ma) and the original Galaxy charger (USA charger - I live in Australia). I have read a few reviews that suggests I may need a higher output charger, maybe a 800ma or 1000ma charger? Would this be correct?
If the phone is still got charger, say 30% battery remaining, and I charge it using a Blackberry or Samsung charger, the phone charges fine, if its completely flat, it won't charge at all.
The phone has not been rooted and I am also running the 2000mHa extended battery mentioned in this post.
Any ideas to why the phone boots up, stays on for 5 seconds and turns off?
Info on charging rates for batteries:
--------------------------------------------------------------------------------
Li-Po (cell phone, RC car) batteries are pretty unstable when compared to NiMh/NiCd (AAs, reg Automobile) batteries.
When Li-Po's first started coming into the Remote Control Car Hobby, the big thing I was told to watch out for, and follow to a T was the charging and discharging rates, because if you neglected them, that's when the cells would swell and possibly burst into flames.
Rule of thumb is never charge at more than a 1C rate or exceed the batteries voltage, meaning if it's a 2000mAh battery, don't charge at more than 2.0A, if it's a 1750mAh battery, no more than 1.75A, and if it is a 1355mAh battery, no more than 1.355A and so on and so on.
For our stock, single cell(3.7V) Li-Po 1850mAh battery, the perfect, ideal charge rate would be no higher than 1.85A at 3.7V.
It blows me away that the stock charger is 5.0V, but Samsung obviously approved it so...Whatever.
I can almost guarantee you that our phones would never discharge at more than the batteries max rating.
To sum this up - don't charge it at more than 1.85A and 5.0 Volts and you should be fine. If you can use a charger with les voltage than 5.0V, I would use that one...

One its a question in the wrong forum .
When flat does it not charge with phone powered off as normal charging practice for a dead phone .
jje
I have noticed this.
My theory is the phone does not charge while booting. So what little charge you had put in, would only be enough to boot, then by the time it can fully boot to charge again, it doesn't have enough power to stay up so it boots off.
If you left the charger on with the phone off for 10 min, should have enough to power up and stay powered. Try that.
Well I bought the Galaxy S3 on the first day of the UK launch and depleted the battery to 0% then charged with the original 1 Amp charger from 0%. I had noticed that this takes a very very long time, around 8 hours. The battery life after charging however is substantial and very adequate.
On the second charge after depletion once again, I decided to use a Griffin 2.1 Amp charger which I had used to charge the hefty Galaxy note with. The Galaxy S3 charges at a much rapid rate and takes around 2-3 hours to reach 100% from 0%. However I have noticed that the battery life depletes a bit faster, Is this due to my imagination or is a 2.1 Amp charger not suitable for this phone as it was with the tablet-like Galaxy note.
Also note that I tried to charge my HTC one X with the 2.1 Amp charger and it charge very slowly, while the original HTC charger has a much lower ampage than 1 Amp
Hmm I have been using my galaxy s charger 0.5amp and it has been charging pretty slowly but seems to deplete faster.
I have been actively using for 50min on wifi now and 85% left. Which seems a bit quick for me. I will try charging with the standard 1amp tonight and see.
Now fast are you depleting at?
I measure my battery life by checking the screen on time just before the death of the charge which was 5 hours on the original charger, with the quick charger its 4 hours. My Galaxy note has no change in battery life weather you any ampere chargers. Also the general battery percentage seems to run low faster anyway on the galaxy s3 using the fast charger.

Just wondering, since the S2 had a limit of 650mA for charging, does this apply to the S3? You guys make it sound like it charges slow as well...
Galaxy s2 does charge very slow for me aswell. Compared to htc phones the Galaxy s 2 charges painfully slowly. Now I regularly use the 2 amp charger on my galaxy s3 and have seen a huge improvement in charging speeds. It charges at around 2% per minute and still lasts around 4 hours of screen time for a full charge.

I noticed that I can only charge fast using original charger. While charger with shorted usb data + & - (ie. htc 1A charger) will not activate fast charging.
You can verify by going into *#*#4636#*#*, Battery, using ori charger will show AC while HTC charger will show USB
I think samsung made some changes to the microUSB pinout

Thanx for the "shortcode". Where does one find those?
Also from reading about the MHL to HDMI cable from older devices not wotking, it does in fact seem that Samsung have changed the microUSB pinouts (although my Nokia 1.2A charger shows AC in that battery "menu").
Mine charges from about 10% to full in about two and a half hours, using the charger provided in the box.
My s2 came with a 0.7amp charger and took about 2.5 hours. My s3 came with a 1amp charger and takes about the same. Charges to 80% in no time and then slows down for the later part of the charge

A battery isn't like a fuel tank which you simply fill up through the hose until it's full.
Due to physical and chemical reasons, a nearly-full battery takes a lot longer to fill by a certain percent since it simply can't store the energy quickly enough.
Additionally, deep-discharged batteries often start with a slower charging speed (and then cranked up) to keep the battery from dying too soon and/or not being able to reach full capacity.
is the Nokia 1.2A charger ok to use with the samsung G3 as i got one of these spare and would prefer use it if so as the usb is way to short to reach from my desk up and around the back.
but the Nokia 1.2A charger lead is more than long enough
Just to check with all of you, i've been told that it is best not to charge your phone or any other handheld device IF the battery is not at a really low rate, at least not till your device actually prompts you to charge. They were saying that this would cause the battery life to be shortened. But at times, I need to make sure that i have enough battery to last me for a few more hours before i knock off from work, i would just charge the phone (battery at 25-30%) even before it prompts me to. Is it alright to do that often?
2ndly, at times when i stream videos on my phone for many hours, the battery would definitely drain fast and i would need to charge my phone at least 2-3 times a day. Is it alright for me to do that or am i "abusing" it? =X
Appreciate all your advises...Thanks in advance~
so any update on if using the nokia charger is ok with it being 200mah more than the standard 1A charger since it has longer lead.
or there is the 700mah samsung charger from my old S2

I don't know why this misconception still lives on; lithium ion batteries require no priming on first use. The WORST thing you can do with a li-ion battery is to fully deplete it before recharging. It is much better to top it off whenever possible; having said that leaving it turned on, on the charger once it is full is also not the best thing (though nowhere near as bad as depleting it fully).
I believe since this phone has a removable battery with external charger the best thing you can do is always charge your battery in the external charger and just switch out the battery when it gets to around 10%.
Nek0onna you should charge your phone whenever it's not full and you have a handy charger.

Can anybody check what the max charge rate is on this device with a battery monitor app? I have handfuls of 1A and a couple 2.1A chargers. I'd really like to charge at twice the rate if possible but not all devices support such rapid charging (kernel limits and such). Just curious before I buy one Thanks!
Even if Samsung slipped up and allowed a 2A charge i'd never want to try it, because tablet and laptop batteries are rated and manufactured for a higher current charge/discharge and most phone batteries would heat and swell up and possibly explode.
my HP touchpad charges with a 1A charger and it would be nice to use that with my sgs3.
Can anybody please check what the max charge rate is on this device
