i accidentally left my gene charging whole night and in morning it showed continuously a red light so i left it out for whole day and now after fully charging battery stays for only 15 mins is my batteries are damaged any way to save them . i thought that battery hack is risky kindly help should i buy a new one
I thought that the battery doesn't overcharge. When fully chared, the battery stops charging.
reply

calibrate batt and try to charge it from external charger then use it .
if not works then replace batt
I have problem with my bettery, bettery dicharge very quickly when i can not use it, sometime when I charge my mobile bettery with another mobile charger, my mobile restart automatically again and again,
I wan't to know is there any problem with bettry or mobile ?
hi!
i was just wondering, my tytn 2 is not charging, when i look at the battery meter, it says charging, but instead of going up. it goes down, the amber light
the signals charging is gone.
im sure its not the battery. coz i did get a charger, the one where u put probes on the + and - terminal of the battery, it charged. the battery is working now. however, i couldnt charge via the phone.
the red light came up before which indicates not charging so what do i do now?
someone suggested to hard reset it. i tried it but nothing. still the same. i reflashed it... nothing... now using the hyperdragon rom... still the same...
any ideas?
btw, when i plug in the charger, amber light is there... however, not for long, light turns off, but the charging / plugged into the charger symbol is there
as far as my personal experience goes, i have noticed this behavior only when the battery overheats while charging. in the hottest weather, this has NEVER happened for me. it only happens sometimes if my device screen is on WITH wifi WITH bluetooth WITH data connection WITH some heavy processing program running. this causes heating of the components and also leaves little power to charge the battery, because most of the charger's power is being redirected to power the components in use.
so, the device will charge for a few minutes and will interrupt the charging if the temperature rises. the charging will resume again when the temperature comes back down.
you can test if this is happening with your device by observing how long it charges before stopping, first without a fan and then with a fan blowing over the battery with the back cover removed.
if the charging lasts longer when the device is being cooled with a fan, then you are likely facing temperature issues.

Try to clean your battery terminals and see if that can help... http://forum.xda-developers.com/showthread.php?t=358136

Your same issue
solved my problem...
i was so pissed, all the solutions did not work... i decided to open it up
when i opened it, i saw that there is some dirt / corrosion on some lines
cleaned each and every one of them.
while it was open, plugged in the battery... then the charger...
after 2 minutes... battery bar went up! it is now charging!!! and
best thing... it also syncs!
Good to know that you solved your problem.
thanks so much. its ur post that really helped

So I used GPS to navigate from NJ to Connecticut. Phone was using car charger and well as being on full brightness and Google Navigation running. I happened to notice the LED light was blinking red which I've never. I had some emails and messages, which I cleared the notifications and read them. The light still blinked red. It continued until I unplugged the charger for a bit, exited out of nav, and plugged it back in, and reopened Nav. The phone was very hot.
I also noticed the car charger didn't seem to keep up with the amount of power the phone was drawing, because it had decreased a little, but not drastically.
Was it overheating? Is this normal? Now I'm in the office charging it normally and there is no blinking red LED, just the typical static red LED.
unless you have a fast charge car charger it wont keep up while using navigation. ive experienced that on every smart phone ive owned. im not sure about the blinking red light. might be because it was in charge mode and was losing power. and its gonna get hot when charging and using gps/nav or playing games
This just happened to me in the car. I took at look at the temperature with a battery monitor and it looks like it happens at around 120 degrees F. Searching other threads (One X) shows similar behavior when an overheat+charging condition occurs. After I blasted the A/C and cooled the phone off, the phone resumed charging (solid red LED) without having to re-insert USB.
Reading up on battery life. Here is what I discovered. Its bad to have the phone running and charging at night, even though their is circuitry to stop it charging when it reaches a certain point. I do, however, need to charge my phone at night to maintain a full battery throughout the day. So why not turn the phone off at night and charge it. I tried it last night and the phone was cool to the touch when I took it off the charger(sometimes its warm when I unplug it). I don't know if that will preserve battery life, but I think this might be a reasonable compromise. Thoughts?
I've always just plugged in over night without powering down. My cell phone is my only phone. I never shut it off. If you are having problems with plugging in overnight then you should get your phone replaced. It's designed to be plugged in without a problem.
The problem with charging the phone when it is powered on, is if you have a faulty app or system process that uses too much cpu power, so the cpu gets hot, also the phone will be trying to use the battery while it is charging the battery, not a good thing, that`s heat upon heat.
I have see this happen a few times, went to pick up your phone and it was very hot.
I use batterybot to monitor my charge and battery temp levels and have a alarm set if the temp goes over 40c, also charge at 80% and discharge at 30% , I virtually never fully charge or discharge my battery as this can damage it and reduce it`s life by quite a bit.

Then that app would have caused an even bigger issue when it's actually in use, and anyone worrying about battery life who has not noticed what is eating his battery power during daytime really shouldn't be worrying at all
I'm currently on Android 11, june patch. Just got the phone this week and noticed something very frustrating. I can generally "fast charging" as i only have a 15w charger for now. But sometimes if I unplug it and plug it back in, it just says "cable charging" i have other chargers and it's the same.. sometimes it says fast charging, but i downloaded Ampere and can see it only at 300mah and only goes up very slowly.. 1% every 4mins..
Anyone else with these issues?
Just try using the official charger and cable because everything else would be way dangerous. The same thing you have mentioned is happening to me as well. Try changing the way cable is plugged in. Turn it upside down.
Im using the 25w charger, Samsung original and neve chared with the stock 15w charger. It shows super fast charging, no problems here.

yeah def charge with Samsung OEM charger
Meh, fast charging only will engage with 25 watt brick that is compatible.
$15 for a Samsung 25wbrick/cable at Walmart online, what's not to like?
I have 2 sets, the first one is over 1.5 years old and still runs A-OK.
jeeeesze...
Yeah i plan to get the 25w charger, just waiting on delivery. I'm just trying to reduce buying so many as i have so many spares from old phone that charge in just over an hour SOMETIMES And over 3 hour at other times! Frustration is even if i unplug and plug it back it, it never seems to go to fast charging unless i let it discharge a little. Winter here and it's cold so temperature of battery has been fine.

Temperature matters. Charging is an electrochemical reaction. Too low a temperature and fast charging will not engage. Charging below 72-82F can cause Li plating to form which will permanently degrade the cell.
Never attempt to charge a Li at 40F or less!
Best battery start temperature is 85-95F
Li's fast charge best in the 90's.
Below 60F fast charging may not engage and it will slow charge for the remaining cycle.
Fast charging will disengage around 80% and at 90% will slow even more. This is to protect the battery.
If the battery temp get above about 101F fast charging will disengage. At around 104F it will stop charging all together.
Cool battery as it approaches 99F with a fan and/or damp microfiber cloth.
At ambient temperatures above 90F cooling will likely be needed for fast charging.

I don't really work with Fareinheit, but after looking, battery is reporting it as around 29degrees when charging. It does seem to be more consistent the last 2 days, i wonder if it's because the OS was still trying to learn my usage. It still happens, i just need to unplug and plug it back in when it says slow/cable charging. But haven't tested it too much, so still unsure.
I am still waiting on charger, i'll keep this forum updated in case anyone else is interested.

Lol, i did. Temperature was fine.
I received my charger after i typed up message. I used it with super fast charging getting 3000mA from ampere app. Worked great unplugging and plugging it back in.
Tested using it on my s10 charger, and it showed up as fast charging, unplug, plugged it back in, cable charging only.
Went back to the 25w charger. It says super fast charging but hovers aroud 1000mA.
Can't get it to use high speed. Temperature at 28.5 degrees.
The only way for me, let it drain 10% and put it in the charger again to get 3000mA charging speed. The message that says "super fast charging" means nothing to be honest.

In what battery % range are you charging? It should draw closer to 4000-5000 ma at its peak fast charge rate with a 25w brick.
About 2%@minute when fast charging at peak rate.
Erratic fast charging can indicate a battery failure.
Any swelling is a failure. Replace immediately it this happens.
Other signs are deminished battery capacity.
Try clearing system cache.
Toggle the fast charging switch on/off 3 times.
Discharge until phone shuts down then charge to 100%. Some say to do this 3 times but one cycle worked for me to recalibrate the battery gauge.
Fast charging is a little b*tch when it goes south but always suspect a battery failure if this happens. A swollen battery can damage and destroy the phone.
Battery failures can happen at any time but are more likely to happen with degraded Li's.

Thanks for the response, with the testing i've done, it's been 70% to 100% only.
i've been needing my phone for work, so i haven't had a chance to discharge it. Will try it this weekend.
Do you charge it back to 100% after a complete discharge with the phone Off or On?

At 70-100% you'll see much slower charging.
Li's prefer frequent midrange power cycling. It can extend their life by hundreds of full charge cycles. Example 40-70%
I rarely charge to 90-100% usually to 65-82%
I almost discharge below 30%, 40% or so being typical. Below 20% there's not a lot of usable energy. It also stresses the battery more when charging from a deep discharge state.
If you insist on charging to 100% at night at least slow charge it to reduce battery strain.

i drained it to 0% until it turned off.
After turning back on, i plugged in the 25w charger and it started charging at 4000mA and max 4750 for only a few seconds for the first 10% and after that, it went down and stayed around 3000-3500mA. happy for that for now. So thanks for your input.
Basically, to get fast charging/super fast charging, don't unplug and plug in a few times unless you have to as it will revert to cable charging, and then you'll need to let it drain a little bit (i found, around 10mins ) before plugging it in again to get the fast speeds.

Having the display on skews the charge curve, don't. It will charge slowly or not all if the display is on.
It you turn the display with it the battery page already open you have one or two seconds to see the display off mAh charging rate.
You can easily tell it's fast charging by watching how fast the battery percentage changes with the screen off.
1%@minute or less slow charging
2%@minute fast charging is active
Fast charging will ramp down depending on inputs like temperature and charge percentage the power controller recieves.
If it starts or goes under/over temperature fast charging will disengage for that charge cycle.
It also will ramp up/down sometimes throughout the below 80% range. This is normal.
Being in the optimum battery temperature range at the start and throughout the charge cycle is important but don't go too nuts. Higher is better than lower. Once the battery is below 70°F it will not fast charge as well (or at all) and/or can detrimental to the battery ie Li plating. There maybe other parameters the controller uses as well... not sure.
Oddly the Samsung 25w bricks are very tolerant of low input voltage. They will charge with as little as 60 VAC!
Like a few have said, fast charging like that will degrade your battery faster due to high temps, but the way you use it has a big impact on that. If you fast charge at those speeds to 100% take it off and use it constant until dead, and put it back on the charger then you will deff degrade it faster. Lithium cells need to rest between charge and discharge to let the the temperature settle. If not it's taking a hugh work load wearing down the internal resistance which drops the cells Mah rating.
Yeah, Im guilty of this too many times lol
Manufacturers know this as well but they know people want fast charging and largest battery capacity possible, they could at least make an option to lower the voltage down from 4.20v and a charger allowing us to switch between a few milliamp ratings..

You're correct it's best to allow some rest after charging and to not fast charge.
In practice this goes out the window
I do try to keep the voltage down as well as the temperature below 100F. Ambient temperatures here are frequently in the 90's
If I get a year out of this new battery I'm good with that.
However once it's down to 80% of its original capacity it gets replaced to avoid a failure. That's what happened to the original battery and I was lucky it didn't damage the display.
Below is my typical usage and the 10+'s fast charging patterns. The last charge ended with a near ideal battery charging temp of 94F. It fast charged nearly the whole time.

Yeah I have a flip top and S4, takes about 30 seconds to change the batteries. Most of the newer Samsung's aren't that bad to change out the battery once you know a few tricks. Some phones with multiple batteries are bloody nightmares though.
Solar panel? That's pretty funny
One way to limit phone usage.
