tips to phone charging

i made this post because people might be wondering about how to charge their phones.
(i say these things from experience so if different for anyone then let me know)
make it a habit not to charger until its at least 15% or less. i always charged my g1 and left it plugged in even at 100 and after weeks the battery life went to hell. i went through 3 batteries that way.
Also try not to use the phone while its charging. i cant really explain what the hell causes that but i know from experience of two other phones that the phone overheats and messes up the battery. so that means avoid over-night charging. i charge mine either before i go to sleep of first thing when i wake up.
also when ur charging ur phone, DO NOT put it under anything, like between a pillow the bed. ur phone will overheat like to the point of too hot to touch. also from experience.

Thanks man,that why my old battery started die'n so fast

I normally do this to calibrate battery:
1. Charge to 100 % with phone on
2. Unplug and turn off
3. Charge to 100% when off (i normally leave it for 10-15 minutes)
4. Then unplug, turn it on, then after fully booted turn it back off
5. put it back on charger till it fully charges again
6. boot into recovery and wipe battery stats
now use your phone as normally and give it 3-4 full charge cycles till the battery is properly calibrated.

Battery calibration is a app on the market. Check it out! It saves you from having to go into recovery and wiping battery stats

i follow all of this and i usually get around 20 hours of battery life. and ive only calibrated my battery once.

Bump Charging has helped!

ok, so I'm running faux's rom and I have run CM 7. I have tested this a few times and each rom and it seems to help improve battery life.
Since the drivers are screwy I noticed when I charged my phone it would say 100% but I would unplug it and it would drop down to 97% right away. I think the lower number is the accurate one, So the battery really isnt getting fully charged because the phone thinks it is so of course it will die sooner
So what I did was let it charge to 100% then unplugged it, it went down right away. I plugged it back in and it started charging again, in a few minutes it showed 100%, I unplugged and it showed 97%, so I kept repeating this then eventually I unplugged and it was 98%, then eventually 99%. After doing this my battery lasted a lot longer. I usually have keep an extra battery on me and usually have to switch but for the first time my g2x lasted the whole day! So give this a shot.. it could help if you suffer from really bad battery life.

Off topic.
Im From Southern California...be visiting New York on Monday. Good stuff...small world some times.

could unplug, then turn off, plug in and charge while off for a while, the unplug and turn on, then plug back in and let charge. then wipe batt stats and unplug. works for me.

I have one extra battery. I never charged my phone through the charger it came with. I always charge my battery with the portable charger. No doubt the portable charger takes 6-8 hours to fully charge my battery, but on the upside my battery lasts for more than a day.

I noticed a similar thing recently. I generally charge my phone overnight while I'm sleeping and use it for an alarm clock. One morning I decided to reboot my phone (my experience is that it needs a reboot every couple of days or various things stop working) before I got up, so I powered it down, still plugged into the charger. I then tried to power it on, but instead of the boot screen I got the device-off charging animation, indicating that it wasn't fully charged, even though it had said 100% before I powered it off. After letting it sit and charge while off for another hour or so, I booted it, and I think I got exceptionally long battery life that day (although my days are all so different it's hard to compare one to another).

I think bump charging does help, but its not good for your battery in the long run

What "method" do u use to charge your Captivate

Hello !
I have read several articles in where people use different methods to charge theyr battery.Maybe it has been talken in XDA too but i havent found nothing that regards charging
How do u charge the battery ?U keep the level from 90 % to 50 % and once a month u fully discharge and than fully charge ?
Or u fully charge it after it shuts off cause of low battery?
Thanks

I'm a bit of a battery abuser, I tend to charge randomly when I think it will be under heavy load such as long drive in the car listening to music I will plug it in with my cigarette usb adapter thingy..
Most other times just plug it into my laptop. My habit for discharging and turning it on until it dont turn back on is maybe every couple weeks to a month if I remember to. Bout that time is when I start cycling out old apps I don't use and just maintaining clean phone status.

...Wall charger every night, all night, while still on, while I sleep. Been doing it this way for 2 years and still using the original battery.

I just charge it whenever it's anywhere between 40-50% and have access to an outlet.

I use USB to charge my phone I plug it in at night around 9 and it's good around 10am then I unhook it. It stays good till about 6 or 7 pm

Lithium Ion batteries don't have memory effect, so the only reason to run a complete drain and recharge is if the battery fuel gage needs calibration.
I leave mine on the AC or USB charger everynight. The Captivate's power management chip reduces the charging current when the battery approaches full. After becoming fully charged, it stops charging for an hour or two, waiting until the voltage has dropped about 0.1 V, then resumes the small trickle charge until full again.
You want to avoid getting the battery too hot, because that will reduce battery life (life= number of battery charge cycles). I have an alarm set in battery monitor widget (bmw) when the battery temp is 45 degrees C or higher. you can get bmw or other battery tools on Google Play.

It is my second time that i fully drain and fully charge my battery.
It is wrong what im doing ?

I don't think of it as right or wrong. You don't need to drain it all the way or charge it to 100% if it is not convenient.
I put my phone on the charger at night even if the battery is 60% or more full, with the phone on. I want it at 100% in the morning. During the day, it often gets charged while I am driving or when I am using my laptop. Is is seldom fully charged during the day, and it rarely gets drained all the way.

I just plug it into a wall socket when it drops below 50% ... been doing it that way for a couple of years and haven't had any issues.

on a normal day, my cappy gets to 10% and under and then i charge it everynight

Yeah, and you want to give 'em hummingbird food for faster charging and best compatability with the captivate's cpu. With this charging method, you can even hear the hummingbird hum if you put your phone in a conch shell and hold it up to your ear.

I have four batteries for my Captivate, because the original seemed sorta crappy, and I found supposed-OEM batteries pretty cheap on Amazon.
My micro-USB port seems to have taken a crap, and the phone will no longer charge via that method. So basically, I have an extra-battery wall charger going all the time, and I swap batteries whenever the battery in the phone dies.

I just connect the usb cable port from my Xbox to the phone when I'm at the man-cave table. At night to my computer's usb port since it still power's up when the computer's off which is convenient :laugh:

Battery discharging while OFF while on plane.

I got on a plane heading from New Orleans to San Francisco via Las Vegas. I turned my phone off just before boarding and didn't turn it on again until I landed in San Francisco. My battery was nearly fully charged as It had only been off the charger for about an hour and I wasn't using it. When I turned it on in San Francisco 7 hours later, it was nearly dead, with only 20% charge. I definitely saw the power off animation. It was definitely off when I took it out of my pocket, but the battery use told me the screen had used up most of the charge. What the hell happened? Has this happened to anyone else?
As a precaution, on the return flight I pulled the battery after powering down. I did not have any battery drain on the flight home after the battery pull.

Maybe the shutdown animation took a very long time and kept the screen on.
I have never heard of this, so I have no idea.

I've had this happen to me a few times. I power off my (fully charged) Charge at night before going up to bed and when I come back down in the morning and power up (and it goes through the power up cycle) I find I have limited battery left. I haven't tried to track down what is happening since I simply replace the battery with a fully charged one and continue on with my day.

I found that I had some file on my SD Card was draining my battery.

I don't suppose you remember which file that would have been.
So when the Charge is powered off it really isn't powered off?

It is truly off when powered down.

I think it's just a glitch of the battery meter. Either it was lying to you when it was full or lying when it was 20%. If it doesn't happen on a regular basis then the battery should be fine, right?
I think we've all had it happen (at least to me a few times) where I switch out batteries that I know have been charged and the phone says that it's dead. The solution I found was to take the battery out and try to power it on, then put it back in or put in the fresh one. I don't know why, but it seems to get rid of some sort of bad juju.

Actually when my phone glitches out and reboots sometimes it shows the battery level more than 50% below what it used to be when it died. A glitch in the kernel that reports the battery level could be the culprit.

[Q] Generic Android Battery Problem

My SGH-S730m (no device forum for this phone yet) battery percentage was at around 80% when I turned it off. It was placed in a pocket with another device. I can 100% confirm it was off for a complete 4 hours.
When I turned it on, the battery level was at 5%.
The battery still charges, the phone still works. The battery has not exploded yet, and is currently at 45% charge. I am using samsungs OEM battery (it came in the box with the phone). I have had this phone for just more than 2 months now.
What the heck happened? Is my fuel guage messed up?

Have you ever tried battery calibration?
1. Charge phone to 100%
2. Discharge to 0%
3. Let phone sit for 5 minutes
4. Plug it in without turning the phone on
5. Charge without break to 100%
6. Repeat 2-3 times

I also is same...

That might be a fix, but im looking for the reason behind this problem.

Does anybody know what went wrong? My phone still works (if that even means anything).

Sometimes it happens that the chip goes mad. It happens with every android phone. You're lucky that you have removal battery. Some devices is difficult to do the above trick. I think when you do a full charge and disconnect the battery from the phone for 5 minutes it will be good again. I'm not kind of advice let battery go to 0 because you can ruin li ion battery with a full discharge.

How long did you have this phone?
Can't you get it exchange for a new one in case the phone has a problem?

I don't know where you from but in Europe you have 6 months for battery and 2 years for phone.

What I meant was, if it's still within it's warranty period you should get it exchanged.
If not, swap your battery with someone and see if it's your phone or the battery.

Indeed.

I won this phone for $7 at a stack-em machine. I doubt it has warrenty.

Sorry pal I can not answer that. But try the exchange battery suggestion from the other user. And try mine for calibration.

Is this a one time only issue or did you get that a lot?
One time only can be from a stuck process in your phone
If you get that a lot => try the warranty

One time issue. I noticed that the phone was getting really hot (even though it was off).

Nope, you can't. It reads 0% while actually it's voltage is way above 0mV (actually somewhere above 3V) and that's a preventive so that you can never discharge it even close to full discharge because going over 0.5V below the nominal voltage would ruin most Li-Ion batteries so it simply doesn't even allow you to do that. And besides, from where do you think it draws the juice to blink the LED when you try to turn the phone on after a "full discharge"?

You should buy a replacement battery then ASAP, they're pretty cheap these days. You don't want Li-Ion packs overheating and the liquid inside them catching on fire.

Li-ion battery are intended to work between 40 and 100 working below that is in most cases the ruin of a battery. And experts say even 98 % slhould be optimal full charge not evem full.

Can you please quote some sources and prove that this is not just a speculation by yourself? I understand the physics of electricity and the foundations of marketing and economy well enough to say that what you wrote is utter nonsense.

Just read the thread from gokhanmoral from here. On galaxy s3 original development thread.
Sent from my GT-I9300 using xda premium

I already know what the problem is. What I want to know is "what" happened to the battery.
Why, would the battery die so quickly when the phone was off? Why, was my li-ion battery discarging the energy as heat? (which would expain the heat while it was off). Why, does my phone still work?
Years ago, I fried a pocket pc by using a 10A charger instead of the usb 0.5A standard (is it 0.5mA? - I cant remember anymore). The battery didnt actually explode, but it got HOT! Really hot. I came back 10 minutes later to discover that my battery was discharging while plugged in..
I fried my fuel guage hardware. Tried to save it, but there was no way. Even after unplugging the 1 pound beast from the charger, the phone was discharging around %4 every 30 seconds. I learned my lesson from that horrific event (I loved that phone so much).
Now, who "actually" knows what happened to my battery? Anyone? I dont need a fix - so dont bother posting if your going to tell me to buy, sell, or repair, and not tell me why.
