remove the battery for 5 minutes, then try to turn it back on.

i try'd taking out the battery but it didn't work

Try first charging the battery then leave the battery out for a while then charging out again for a little bit then turn on

Was the battery low when this happened? Sometimes when a battery dies completely, it takes some time to get the battery charged enough for the phone to boot.
If you can, try a different battery or go to a Sprint store and have them give it a boost.

Mine has done that before.
1. Unplug phone from charger
2. Remove battery for a few minutes
3. Insert battery and plug into charger (do not attempt to turn phone on)
4. Let phone charge for about 30 minutes or so
5. Turn phone on

The battery is undercharged.
Either take it to a Sprint store for a boost or plug it up and let it sit until the amber light goes solid.

Also better if use the wall charger rather than a car charger or charging off ur computer. I've had it happen to me and the battery is just fully drained. Pull battery insert battery plug into wall charger and wait a long time. Blinking light will turn solid amber and eventually charge fully. If not then take to sprint store

Do I need a new battery?

I own a HTC wildfire. I have some issues with my battery and I can't pinpoint out the reason, these are the issues:
It rarely charges to 100% unless I let it charge for a while and then reboot the phone. But it'll drop really quick
If its charging while switched off and I take the charger off, the charging light will stay on indefinitely
The battery goes really quick, in 90 mins my battery charge is now 38%
When switched off and charging, it never gets the green fully charged light, but if I switch it on it'll say 100%

Phone charging really slow??

So my s2 has been charging really slow, like today it took like 5 hours to fully charge, and when connected to charger if I'm using it it wont charge very well, like the battery will stay at lets say 20% when im using it and charging it, it might even go down more. it used to charge pretty well even if I was on it. Cuz this be the charger, or is my battery messed up?? Im using the charger that came with the phone.

Are you charging through a usb port on your computer or ac? If it is with usb port then yes it will charge at a much slower rate. Also if you have a lot of apps running or backround data going it will also cause your charging to slow down some. I would say through usb without any apps open and backround data stopped It would take a few hours to charge say from 20%. Through AC in the same condition probly 1.5 hours. Try to reboot your phone and then plug it in to charge to see if that doesnt speed it up any. If it does then you know you have backround data moving at a fast rate and that would be your reason to slow the charge down.
Yeah I'm charging with the wall charger, not thru usb

thats pretty weird...have you tried using another usb cable?? maybe the cable is faulty?
Calibrating the battery

You could try calibrating the battery, maybe. To do that, turn the phone off. Charge to full (make sure it's full, by taking it off of the charger and putting it back on...the indicator should read 100% almost immediately when reattached to power).
When the battery is full, with the phone still turned off, remove the battery for about 2 minutes. After 2 minutes, reinsert battery and restart phone.
Battery will be calibrated. This may not resolve the problem of a slow charge, but will clear 'battery memory' which may have been preventing it from charging completely (and, I suspect, may have inhibited charging).
Good luck!
I was using an aftermarket wall charger and had similar results. Switched to the USB/AC converter that came with the phone and all was well.

Yes, try Battery Calibration from the market. Only works on rooted devices, and follow instructions.

Actually, one doesn't need an app to calibrate the battery. If you follow the instructions above, the app is unnecessary. And the phone mustn't be rooted
YODA? ^^^^
Hey elflip88, have you found the issue yet?
I have the same problem on my HTC Amaze 4G. It's charging 1% every 3 minutes (adds up to 5 hours)
I'm also using the wall charger...oh damn, I'm starting to think I have a faulty device / battery...
yelp!
For the record Samsung devices are known to be slow at charging so with that considered.... You still shouldn't be at 5 hrs. I would find a battery stats app charge your battery over night and check the chart to see exactly how long it takes to go from 0 - 100. Make sure your batter status is good. Also check the voltage coming into your phone from your charger. There are plenty of battery stat apps in the market that will do this sort of thing. Of course make sure your battery doesn't have water damage of course too lol.

I've had the same problem with mine. But, I can get 1.5 days without charging and moderate usage. Charge it up, drain it, charge it back up then wipe your battery stats in recovery.
This may help if you're using an aftermarket wall charger
If you guys are having issues with slow charging using an aftermarket wall charger, it could be that the phone is charging in a USB state rather than an AC charging state. QuickCharge could alleviate your issues. The cable is inserted between the wall charger and the USB cable that goes to your phone. You can find the product on Amazon. It's the 2nd of 3rd item from the top when you search 'QuickCharge'.
I find that when I fully drain my battery and charge it, it's really slow. Once the phone has enough battery to stay on, I unplugged it and replugged it and it charges normal again.

It's your wifi and your apps using wifi. Turn wifi off while charging. I used to charge 4 hours + on my S2. Reduced to 2 and some change when I turn off wifi.
Also, I struggle to make it through a working day with wifi on. Turn wifi off and I can do 4 days no problem.

I old suggest using a different outlet if you haven't done that yet.

Force battery to fully charge

So I've noticed for a while now that when I disconnect my dInc after charging, the battery will drain almost 20% within the first couple hours (almost no use at all). I suspect that the battery isn't being fully charged when the green light first goes off. After I plug/unplug the cable and charge a couple more times, it holds a higher charge more consistently. I've read this is due to the phone not wanting to over-charge the battery, however in the case of my battery (Seido 1750), it doesn't even fully charge.
Is there any way (aside from the plug/unplug scenario) to fully charge the battery in one go? An app maybe?
My phone is rooted.
Thanks.
The battery could be losing its ability to hit its capacity. In other words its wearing down.
Nothing will fix it. There are no apps to bump charge.

Get an external charger for your battery and couple of extra batteries. I get best result not charging in the phone and rotating batteries.

Charge the phone powered on until the light turns green. Leave it plugged in but turn it off. Leave it plugged in, off for about 20 minutes, you will notice the light is still orange even though its already "charged." Once the light goes green again, unplug it and power it up. When I do this, my battery will go for 3 or 4 hours before it hits 90 percent with my regular use.

Just be aware that bump charging as it's called, can reduce the life of your battery over time.

Battery Problem?

One night my phone was dying so plugged the charger up at 1% but even with the charger in it went to 0 then cut off. no "powering down" pop up like normal so i went to bed and let it charge. when i woke the next day after about 8 hours it was on 76%! normally it would have been fully charged. Now its really long to charge. Can someone help and tell me what's going on?

Is there any app loading in the background? Strange though...
what ROM and setups are you using ?? some of the 4.2.2 roms charge really slow and if you are not using the charger that came with the phone than it would take longer
I'm using Cm 10.1 normal settings. I haven't been using the charger that came with the phone ever. It started acting only after it shut off at 0%

its not recommended using other chargers it sounds like you are not getting enough juice from that charger/wire..... but if you are make sure your battery never dies because the more it dies the more strain you are putting on that battery also you will be better off using the usb wire and a computer to charge are you familiar with FAST CHARGE ??? i would suggest getting another charger
Edit: i have a nexus 7 and i had your problem before i have an after market 10 foot usb wire to charge my phone but when you are using it or there is an app that is draining it it will not charge because there is not enough power coming from the wire but if i use my factory charger for the nexus all is good on low battery and it charges so yeah ... just an fyi
also ive noticed that with some kernels that the battery charges faster
but just play around with different roms or just get a new stock charger
If u are using AOCP with stock kernel, idk why but it has ridiculous slow charge. Install a different kernel and you should be fine

[HELP] Battery question

My wife has my old S2 and the past day has noticed it only charges to 52%.. She tends to play on the phone doing miscellaneous stuff thru the day and when it gets low just plugs the charger in and continues to play.. I know on my S3 everynight I allow it to get down to about 2% then will plug it on until it reaches full charge 100%.. Should I allow hers to fully discharge til the phone shuts off and let it get a full charge cycle the next couple days iin hopes of "re-training" the battery cycles or is there something else I should do.

Lithium battery's don't have a "memory" like nickel cadmium batteries. They would die quick doing what your describing over time. Lithium doesn't work that way.
In other words, I wouldn't worry about it.

Method 1 – The Drain Way
Drain it down until fully dead.
Charge normally to full.
Reboot to Clockwork recovery and wipe battery stats (under advanced, on second page), reboot phone.
Turn everything on, flashlight, Bluetooth, Wi-Fi, Pandora, the whole nine, to quickly drain it completely dead.
Charge normally to full.
Method 2 – The Powered Off Charge way
Charge your phone 100% while it’s on.
Unplug it from the charger, power off, then charge it up to 100% with it in a powered off state.
Unplug charger from phone. Power it on, and then charge it to 100% while the phone is on.
Unplug the charger and then reboot into Clockwork, go to advanced and clear the battery stats.
Power on, charge to full, and then enjoy.
Method 3 :
Start with the phone powered on.
(Phone on) Charge battery until the LED turns blue
(Phone on) Unplug the phone from the charger, wait until the LED turns off
Power off the phone.
(Phone off) Plug the adapter into the phone, charge it up until the LED turns blue
(Phone off) Unplug, wait until the LED turns off
Power the phone on.
Wait until the phone is booted back up all the way, and then power it off again
(Phone off) Plug the adapter into the phone, charge it up until the LED turns blue.
Boot the phone into recovery mode
Go to Advanced, and then choose Wipe Battery Stats.
Power the phone on and use normally.
You really dont have to reboot into recovery and wipe battery stats as that doesn't really work but to get all your juice back its going to be a few cycles also this works pretty good as well https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en
