If I shut off the phone it will charge but when I turn it on (while still on charger) it starts eating the battery down within 30 minutes its dead only stayin on by the charger but eventually dies. If I charge it and take it off charge it lasts maybe 30 or 45 minutes.I bought it from a friend so dont know if it has a virus or not. Ran anti virus and it said everything was fine.The light blinks on it, it doesnt stay solid like it should.What should I try before I spend 50 dollars on a battery.

Fix an Android device that won't charge or turn on If your Android phone or tablet isn't starting, won't turn on, has a black or blank screen or turns on but immediately turns off, try these steps to fix the issue.
First, try holding down your device's power button for five to seven seconds. This usually restarts a device.
Step 1: Troubleshoot your cable, charger, wall socket & case

1. Use the charger and cable that came with your device. To check that the charger and cable are working, try them with another device.
2. Check that the cable is securely connected to the charger and to your device. Check that there's nothing in your device's port, such as dust or lint.
3. Plug the charger into a wall socket. To check that the outlet is working, plug in something else, like a lamp.
4. Check that no accessories, such as cases or battery packs, cover your device's sensors or press its buttons.

Step 2: Troubleshoot your battery charge Within one minute after you've plugged in your Android device with a working cable, charger and wall socket:

• If you see a battery icon, your phone is powered off and is charging. You can restart right away.
• If you see a red light, your battery is fully discharged. If the red light is flashing, there isn't enough power to turn on. Charge your phone for at least 30 minutes before restarting.

To restart your phone, press and hold the power button for a few seconds. Then, on your screen, tap Restart . (If you don't see 'Restart', press and hold the power button for about 30 seconds, until your phone restarts.)

Step 3: Troubleshoot your screen If you don't see a battery icon or red light after you plug in your Android device, the issue could be with your screen.

1. Press the power button for about 30 seconds.
2. Wait about 2 minutes.
3. Make your phone ring. You can call it from another phone or use Find My Device.

Hi mike , you could try a car battery charger to bring the voltages up but this rarely works , sadly your batteries are nearly dead..

One thing to note , check the charger , if the charger bad then the batteries will reflect that ..

Regards

To reset the phone, it should be without power at all. So removing the battery, when the charger is connected, will not reset the phone. Then when the battery is dead, it could show up as if it is charged, because the voltage on the voltage sensor can become high enough, to indicate the battery is charged.
First, disconnect the charger, and remove the battery. Wait a few seconds and reinsert the battery. Try switching the phone on. If nothing happens, the most likely thing is you have a bad battery.
I hope there is no other issue.
Success.

Charge Doctor Diagnosing Some Common Charging System Problems

The red clamp on the charger goes to the + sign on the battery. The black goes to the -. I you want a deep charge(best) set the charger on 2 amps and run it for 8 to 12 hours. If you need to get the car started, set the charger on 225 amps for just a couple of minutes. Start the car while it is on..2 amps can charge forever. 20 amps for 30 minutes. 30 to 40 amps for 15 minutes. 225 amps for five minutes..DO NOT charge 20+ amps for hours. It will kill the battery

Battery may be dead or just gone bad. If anything comes on the screen within 10 minutes after you connect the charger but the phone does not charge, your battery is dead or bad.If the battery wont keep charge, it's bad.

Either the charger is bad or the batteries are too old. If the batteries are allowed to go dead completely the 24 volt charger will not recover. You'll need to seperate the batteroes and use a 12 volt automotive charger to charge the batteries. Make sure the 12volt charger is able to charge gell cell batteries. Not all will.

Are you sure it was fully charged before? Could you see the full battery bars?

It sounds like your AC adapter (the charger) has likely gone bad. The phone battery probably wore down, and when you plugged it into the charger, the charger couldn't charge it, so the battery remained dead.

Since the battery is not charged, you can't turn the phone on at all when it's not connected to the charger. And when you do connect it to the charger and turn it on, you get the intermittent charging because something inside the adapter has a faulty connection -- sometimes it works, sometimes it doesn't.

You can easily verify if the charger is the problem by getting a new charger (they're not too expensive) and seeing if the phone will work and/or charge with the new charger.

If the new charger doesn't fix the problem, post again here and we'll go from there, but I think the new charger will take care of it.

Hope that helps!

Your Battery Is maybe Too Old, If the Phone Is Very old Then The Battery Is Just dead Because Of too much Use.


Hope it helps.

Yes it is the battery. First try charging it with trickle charger. NOT car battery charger. It should work fine once it is charged enough to start the bike. Than the bikes should keep it charged. Or you can jump it with car battery. This is safe. THe motorcyle battery is also 12 volts. Just smaller.

After the bike runs for 5-10 minutes and shut if off. Wait 5-10 minutes after it is off and try again. If it does not start again, than your battery is either dead or your stator/rectifier (your charge system) could be faulty. Lot cheaper to get battery for $30 than to pay $75 hourly shop fees for testing and than repairing.
