Alright, so I have a mini USB car charger that is rated at 2.0A (got with GPS) and I just want to make sure the extra amperage is not going to charge my battery too quickly and then kill it in the process. All I have to go on is that my wall charger is capable of only 1.0A and the computer USB is on the level of mA. Does anybody have a car charger or know the maximum amperage possible that these phones can take?
Thanks in advance.
Its to Strong ! I have Crash a PDA with 1.5A
I've used a 2.0a charger but noticed that the battery didn't charge right.
On that note, also noticed that a .5a or 500mA charger after about 6 months killed my battery. (burned out and won't take a full charge anymore)
Recommendation is to stick to 1.0A charging as much as possible as the Wizard's charge circuit is designed at 1.0A charging and monitoring.
DOESN'T MATTER ..if u know the basic Ohms Law..its the max capacity of the charger.(or any source) the current regulating circuits will take care of the real charging current fed to the battery
I charge my phone on my computers USB connection all the time, all computers have a maximum of 500mA USB current.
Amps are pulled from the charger, not pushed to the phone.
Voltages are pushed to the phone, not pulled from the charger.
If the phone draws too much current from the charger, the voltage drops to a point where the maximum power (P (Watt) = U (Voltage) * I (Amps)) of the charger isn't exceeded.
According to the USB specification you need at least 200mA with 500mA recommended +5VDC.
More is never a problem, you could even use a 50A power supply without breaking your phone. Practically spoken: I wouldn't do that.
huh?
I have messed up a few devices before by putting the wrong charger on the device (2.0 amp charger on a droid eris and 1amp charger on the MOTOACTV) Is this a problem with the device's charging circuit? In general it should only pull up what it needs to charge but my devices were messed up?
I returned the first MOTOACTV after it wouldn't leave the boot screen and the second one I got acted funny on 1 amps as well. It charged fine on .75amp charger that came with the device but when I put it on my HTC Dinc charger it shot up from 10% to 20 to 30 etc. all within minutes. Hope I didn't mess this one up too.
Just trying to figure out what the deal is. My phone for sure charges faster when connected to 1amp vs .5amp (computer). This makes sense I understand because the device is able to handle 1amp, but I wonder if it would mess up with a 2amp charger.
Thanks!
The last two posts of 2008 are correct. Your phone is capable of drawing more than 500 mA but less than 1000 mA. If the charger is 1A, 1.5A, 2A, or 50A, it won't make a difference to the phone's charging time or life.
Wrong voltage can be bad, but phones are designed to support USB charging, as a minimum, and 1A to 2A is always safe. As was said in 2008, the charger pushes voltage to the battery, but the battery pulls current from the charger.
That's a really good way of describing it
Pushing and pulling current and voltage is a really good way of describing it.. Given that I am theoretically well within the charging parameters, how comes my phone (Galaxy mini/pop) becomes unusable when its charging (touch screen doesnt touch and screen jumps to new screen without touching?) Am I wrecking my phone?
No, your charger is to blame. Maybe it isn't properly grounded. Phones with capacitive touch screens (not the Wizard! but maybe your phone) can get really weird on some chargers. I have a Nexus One with an aftermarket charger that always makes the touch screen go haywire. When I use an HTC charger, the phone has no problem. As far as I know, the damage isn't permanent, it's just that the sensors get confused. When I disconnect from the charger, turn the phone off, then turn it on, all is well.
My wizards were never bothered by chargers, no matter what kind, as long as they were mini-USB, they were the right voltage. The wizard doesn't take as much current as more modern phones, either.
Hmm. Not properly grounded sounds very plausible. Viva mediterranean circuits. Thanks
Usb chargers will be rated at 5v, which is exactly the correct voltage to charge your device. What you want to make sure is you buy the correct "rated" amperage. Not because it will damage your phone. Amperage only exists as a sum of the power used by the device. You want to find a decent 1amp (1000mA) or higher if you wish, rated usb charger. The the mains charger for your phone is only rated at 1amp, so a 1amp charger is adequate. Avoid 500ma chargers as it will take twice as long to charge and gps / satnav applications will drain the battery even when charging at that rate.
Also if you have a new pc, most of the decent boards will specify 1amp charge even when off if it has on/off charge stated on manufacture details.
Newer phones will charge fine with higher amperage
The myth that charging your device at a faster rate will reduce the life of your device’s battery is false!
If you want quicker charging, look for a wall or car charger that delivers 2100 mA of current at 5 volts higher won't matter.... These lithium ion batteries can handle it... It was just back then if you were to try to put a faster charger in an older battery it (in any cases) just won't charge.
Hello,
I have the three EVO 4G phones and one EVO 3D phone. Along with a few different car chargers including ones from HTC,Rocketfish, PointMoblm, 12v USB radio plugin,12 volt to 110volt with USB plugin and wall charger plug.
The problem I am having is when I travel distances over 100 miles using GPS "Google Maps" and/or Pandora streaming. The Battery get so hot it stops charging or will randomly reboot phone and the battery is dead or close to being dead when I get to my destination.
Is there a way that I can run the phone without the battery or software mod that will stop battery charging in different time intervals while in car mode.
Any tips or modifications on 12v chargers I can try?
Maybe you could try under clocking the cpu during these trips.
Reducing the CPU will reduce the heat it produces as well as the drain on the battery. Both will help with your heat problem.
I have the same problem with my E3D and the underclocking didn't work. My phone is underclocked when the screen is off, but when I picked it up it was like hot coal.
I paid a total of about £2.50 (£1 for car USB connection + £1.50 USB cable) for the charger, so was wondering if it's the quality of the items.
I plug mine into the cigarette lighter too, so don't know if this is part of the issue.
I will try to lower Cpu during AC charging first since my primary charger charges at AC.
How low should I start? I have SetCpu to max 486 and 192 min with screen off.
Hi. What's your opinion of this amps values for cable when is charging? Thanks
I have been using Aim rom for around a month with a single problem of shuting douwn at 10%. To fix this issue I calibrated manually by discharging the battery completely 0% and charged to 100% while power off. At 100% deleted the Batterystats.bin file located /data/system/ .Now the battery goes to 0%. After one or two charge cycle (0% to 100%) my mobiles charge rate got reduced to 100mA to 300mA also the voltage is reduced to around 3.6V form 5V. My mobile spec supports 5V 2A so to test I connected it to 5V 4A charger and the the current was around 1500mA and voltage around 4V.
When my mobile is switched off the led blinks on charging from 2A charger. Also by connecting to laptop it just charges with no usb options. The 4A charger seems to be working but worried of hardware damage.
I have already done all the troubleshoots including,
Trying differnt cables of 2A.
Trying differnt adopter of 2A.
Cleaning the usb port of mobile.
The batterys health is proper (4 to 6hr of heavy gaming).
Im using a custom rom and when I charge the phone with the screen off, its taking 9V 1.6A electricity from the socket as it should be. As soon as the screen is turned on, whether it is a notification or manually, the current intensity drops to 5V 0.65A. After the screen is turned off, it doesnt go to 9V, stays at 5V 1.50A. When I use it while charging, it get 5V 0.65A. Supposedly the fast charging feature is turned on. My charging adapter is 20W and supports power delivery. I charged my phone with other roms and they charged my phone as it should be 9V 1,75A. How can I fix this? My phone is rooted by magisk btw. So I can edit the system files if necessary.
