what will happen if i use 2A charger?
will it charge faster?
will it damage my phone/battery?
or nothing will happen because my phone/battery will draw max 1A (or whatever amps it set to draw) from the charger?
It can damage your battery all tho it can work for a long time but at the end it can damage your battery

how long is that "long time" compare to normal degradation? if it can charge twice as fast, and the degradation is less than... say 30%, or until Garmin come up with Android version, then it's worth the charging time, that is, if it does charge twice as fast.
did you ever plug your phone to usb 1 and when your battery is at 10% get a pop up telling you the power is not enough? it seem the phone is smart enough to know the amp coming in is lower than what it using. if you never see it, you can duplicate the event by charging via usb hub, and connect the other port to whatever device you have. when your battery reach 10% you will get the message. so it might be possible the phone can regulate the amp it draw, maybe a bit higher if the charger can supply more than 1A.
Hi guys,
i want to ask - my phone charger has got these parameters -
input : 100-240VAC 50-60Hz 140mA
output : 5.0VDC 850mA
battery parameters :
BST-38
970mAh 3.6Wh
isn´t the charger too strong for the battery ?
charging my battery to 100% takes about an hour,sometimes less.
after charging the battery is quite hot.after 5-10 minutes the battery gets down to 80%, and it is stable from 80%.
i am charging just via USB now, because of i think that the charger is too strong and i think it can reduce battery life...?
what do you think ?
Yeah, it is strange.
The battery drains pretty fast after charging to 100% but later it is stable. Although I didn't notice that battery is hot, I think that charger charges battery too fast which is not good for battery IMO.

No, its not charging too fast. Lipoly batteries have pretty tight specifications and the phone switches the voltage itself, for terms of compatibility a usb voltage is used (so less hardware is needed to step voltages from different sources). It also means you can charge from your pc without having a bypass cable like older model phones.
The mA output of the charger doesnt really matter. A high mA means the voltage will be more stable where as a low mA supply could cause undesirable voltage fluctuations.
A lipoly battery cannot be slow charged or trickle charged, the chemistry doesnt work that way. Slow charging could actually cause the battery to explode or in the very least make its performance poorer.
The battery appears to drain quickly in the first 10% but its an illusion caused by the software on the phone which measures the mAh drop. A lipoly battery may discharge from 1200mA to 1000mA in 10 mins and reach a plateau where is holds 900-1000mA for several hours. All that is required is to reset the battery stats so the phone can generate a new profile over several recharge cycles.
As I said, lipoly charge until near capacity and stop. They dont trickle charge, the charging circuit actually switches off. Those people who leave their phones plugged in 8 hours overnight do it no favours as it justs cycles the charger on and off, this could actually skew the battery stats giving a false reading in the first 10%.
The best thing is to charge until full and then remove from the charger, you can always charge it again in the morning before you go out to boost the %. For the best battery life you should maintain a charge above half as this keeps the chemistry from breaking down. Never ever let it go flat! When the phone registers 0% its not, its a safety mechanism and it will still have above half the rated mAh. Charge a dead lipoly and it will explode violently.
Using alternative charging methods of a lipoly is VERY dangerous. People have lost houses or even their lives by fiddling with them. They are not a forgiving as lion, nimh or nicad. With that said lipoly are cheap, reliable, have a small form factor and offer a high output in comparison.
The best device for charging the battery is the phone charger as it has the highest mA and most stable voltage. The PC comes second as most are only rated 500mA and can have voltage fluctuations in the range of 10% or more. Third... Nothing, there is no third - only flames and misery.

Just notice this, just now i see this screen when charging with phone turned off. I try 2/3 different charger from other manufacture still the same, but all charger works when phone On. Any solutions will help. Thanks.

That indicator means the Streak isn't recognizing the cable, so you have one of two possible causes here:
1. The cable is bad
2. The port is dirty or bad
To properly troubleshoot, clean the port with a cotton swab and rubbing alcohol. Let the port dry, which should only take a couple minutes or so. Then plug the cable into the port. If it still doesn't work, try another cable. If it still doesn't work after that, the port is likely your culprit.
will try. thanks.
edit ; but, just found that if connected to the computer when screen off, it's charging properly. So this is maybe charger incompatible issue ? i don't have original Dell Charger, so from the day i hold this lovely device i use random wall charger adapter from my blackberry, LG and iPhone.

you know.. it is quite bad to mix use of wall charger.. since it would affect your battery... try to use just one charger and stick to it... i use samsung galaxy tab original charger with rating 5V 2A by the way...
Ya i think u right. 1 more question if you don't mind, sometimes... i just need to 2-3 hours to perform full charged. But somestimes ( usually in some miui ROM ) i need more time like 4-6 hours to full charged. Whats that ? I try using Battery-Calibrating apps from market or manually deleted batterystat file, its result randomly, sometimes working, sometimes not. Can you please explains more about battery... thanks.

usually when we flash rom over another, the previous battery stats would be used... so doing a recalibration would help to get back the actual battery stats...
so.. when you notice the charge length is not correct or it is not like usual... doing recalibration would help..
charge half way... or you charge and then forgot bout it until the next day... something like that would affect the battery stats also...
if you maintain the charge cycle appropriately .. it would help the battery stats maintain the correct value too...
i also sometimes forgot bout the battery.. i mean we charge the battery and then goto sleep... if the charge is only 3 hours but we sleep more than 6 hours the different of 3 hours there would make a difference to the battery stats... where the stats would start to get hayway ..
yes, i do flashing frequently, i quickly got boring with just one rom
and yes, i charge my phone before sleep almost everyday, is that bad ?
right now (with miui rom) for example : when battery indicator show 39% after charhing 4 hours more, disconnect cable, i turn it off, i enter recovery (this weird, it boot in recovery, as i know, we only can enter recovery if we have above 50/60% battery, right?) so i wipe batterystat and reboot... voila.... its show 75% ???
how come ?
in some calibration apps say :
" Its not necessary but recommended to use phone until it shutdown it self, and recharge without a break start with phone off"
since i can't charge with phone off because of my incompatible wall charger adapter, so i never complete this above step. is it really needed to be done?

This is only partly correct.
The battery would be affected if the output voltage of a replacement charger was different from the stock charger, although it is more likely that the Streak's circuit board would blow a component or two. However, the battery will not be affected by the output amperage of a replacement charger. The only thing that will happen is the amount of time it takes to charge the battery will increase or decrease depending upon the amperage the adapter puts out.
For example, 4.0V, 2A is a bad thing. 6.0V, 2A is definitely a bad thing. Both can do damage to the battery because the voltage is what has changed. However, 5V 1A or 5V 3A won't hurt the battery at all since the only thing that changes is the amperage. As added protection against damage and/or battery explosions, there is a voltage control circuit inside the battery that not only monitors the individual cells that make up the battery but also can measure the incoming voltage. If the voltage is too low or too high, the battery will cut the charge circuit and prevent an explosion. The circuit doesn't measure the amperage because it doesn't need to, and thus the battery will happily charge at both lower and higher amperage than recommended without damage.

thanks for explaining, so its okay right if i use 5.0V 700mA ?
Sent from my Amazon Kindle Fire using Tapatalk 2
It will work, but it will take longer to charge as it's only 700ma versus the Streak's 1A. The charger may become slightly warmer as it has to work longer, but otherwise you should be fine. Had the difference been greater, say using a 500ma charger when a 2A was required, you might damage the charger, but not the battery.
okay thanks, now i know how to charge my battery

Hi guys does anyone know how we can limit voltage when we charge ur phone?
What i use is rooted phone with ACC + AccA ront end but some bug you always have to check because most time AccA doesnt apply limit voltage as i ask.
Any better solution?
Why you need to limit the voltage? If you want to help battery to stay in good health for longer you should limit the charge current instead. Easiest way to do that is to use older charger with lower wattage. I usually charge my pixel 6 from my laptop which has type c ports with usb power delivery support and are limited to 12 watts so charge current never exceeds 2.1 ampers. I have also tested my old power bank and cable and there power is limited to even lower 7.5 watts or 1.5 ampers of current.
On battery university they said, the voltage from the charge is the problem not the amp speed, for example when your phone is at 3.8v(30%) and you charge with a quick charge 3amp at 4.05v(not 4.25v) you quickly recharge until 60%(4v) and you slowly and you reach 4.05v(+-70%) and you can let your phone charging longer you want the voltage never go over 4.05v and at 4.05v the said atfter 2000 recharge cycle you still have 90% of brand new battery capacity.
Your phone said full charge at 4.25v but with lithium ion it overcharging and that really dommage you battery life.
So in real is not the % of capacity because when you charge your phone to 80% diring the charge process the voltage use to charge is 4.35v and that is bad for the battery
BU-808: How to Prolong Lithium-based Batteries
BU meta description needed...
batteryuniversity.com
"Every 0.10V drop below 4.20V/cell doubles the cycle but holds less capacity. Raising the voltage above 4.20V/cell would shorten the life. The readings reflect regular Li-ion charging to 4.20V/cell."
basically I have the s23 ultra, the 313 ace charger 45w . and a 5A /100w cable ..
past 3 days it says "super fast charging 2.0" and displays the blue circle. for the duration of the charge..
now 5 hours ago, I plug in and see the blue circle, and the super fast charging 2.0 but after about 15 seconds it displays the green circle and says " fast charging"
I unplug and replug .. same thing happens..
so my question to the L337 developers on the site, can you force the phone to quick charge 2.0 with an app? or some setting hidden in some secret dev window?
I know the hardware can handle the charge and I've changed zero settings in the phone so it's definitely a deep seeded software issue. I've cleared the cache , double checked basic toggles. I'm lost.
There may be nothing wrong.
Phone throttles down charging based on battery charge level. When battery gets above certain level it will no longer charge at full speed.

I started the charge at 20% .. so you're saying the phone decided to limit the charge to 15w because it was above what exactly? 21% ?
back to my original question.. phone starts at super fast charging 2.0 , and then 15 seconds later it throttles to "fast charging" .. is there a way to force the super fast charging 2.0 protocol because the software is whats limiting it.
Just get the original Samsung charger brick.

You didn't report the charging levels, hence my 'may...'.
Anyway, 20% is too low.
I do not know the exact levels (did not conduct a thorough test), but at least at 70% with my samsung 65W charger (Galaxy Book2 360pro) and 100W cable there is no more Super Fast Charging 2.0. I have S918B/DS, CSC EUX, SFC is there at least below 50%, no software limitation there...
What is limiting your charging I can't tell (Charger, Cable, Phone SW/HW...?)
