The battery dies after sitting for a few hours ? Parasitic drain on the battery ! With the key off all fuse's shouldn't be hot ! Bad ignition switch . Find a wiring diagram at www.bbbind.com an check power at ignition switch . Look on you tube , a lot of videos on basic electrical trouble shooting .

Why the battery drains off to one point in hour in Nokia N70 with out any operation? The same battery retains full power more than 24 hours when removed from N70.


i think that your battery's lifetime is over. try with a new battery. but make sure to buy an original battery. don't buy cheap chinese battery.

My phone keeps shutting on and off and wont charge when plugged in


Cell phone batteries have what is called a "memory" over time if they are charged without being fully drained they can start to not hold a charge. Unfortunetly the only fix for an issue like yours is to purchase a new battery. Your local retailer / service provider should have batteries in stock or they can order one for you.
It is recommended to allow the batteries to drain completely before charging, then allow at least 8 hours or more to fully charge. Most cell phone will show a full charge after a few hours, but this is more a fault with the software that check the batteries charge, then an actual indication of the battery being fully charged.

Samsung galaxys 2 drain battery fast


The power cell should only get warm if you have it powered on all of the time. That is natural. 6 hours is short, and that may be one of two problems, the time of charge is too short, or the battery is dying. HINT! If you replace with a NEW battery; you must set the battery memory for the start. That means, when you first charge it, make certain it gets a long 24 hour charge to full. Use the phone until the device shuts down because the battery was exhausted. Now Do a full long term Charge. That process will set a Memory for the Power Cell and allow you to fully charge and discharge the battery from there on. One more thing...if you use a Charger Device, make certain it is working OK or else the Battery will not charge well.

My phone will not charge. I can connect it to the charger and it looks like it is charging. Remove the charger then phone goes off. I charged the battery with a stand alone charger then installed battery....


It maybe a problem on the phone already and not on the battery. Something inside the power ic / board that's why any battery will not hold charge for long. Try also draining the battery and then charging it for a full 2 hours with the phone powered off as this charges the phone faster.

My Sony Ericsson K810i Mobile have a problem. It shows the charge indicator nearby 99 % and if i speak a cll it goes very low and says 'attention Battery Low' and if i leave the phone to standby it shows...


Hi, problem can be solved. When a phone battery indicates 99 % of battery life and runs down so quickly, it is caused by damaged battery.
When a battery cell is damaged, it will display charging full but itwill empty. You will need to replace the battery for a better battery performance.

When a new battery is been purchase, make sure it is charge it is charge up to 4 to 5 hours before use.

Phone is charged but is continuosly losing power. How can batteries run down when it is charged?


Unless the phone is showing any malfunction we cannot confirm unless a drain test is taken in the standby condition of the phone.This must be quite negligible current about few mAmps . If there drains is more check for leak in the battery source to the IC feed, a possible zener shorting or a capacitor leaking.
However if the phone is using up power on talk time , it can be due to drain in a functioning circuit which will be hard to find , but check for unusual heating in any components.
If however the phone works fine then it can be the fault of the battery itself as it could have developed reverse polarity.
Let the battery drain off fully and recharge, if possible a jump charging with an external voltage might sometimes cure this issue.
If not change the battery with the correct current rating.

Good day sir/maam, your battery is bad, replace it. If still gets hot, you may need to bring your phone for service. the charging circuit maybe faulty.

Nokia n81 running a new battery down in 6-8 hours on standby mode


Even if the battery is new, if it is not charged properly it can run down pretty fast. To reset the battery I recommend running the battery all the way down - charging the battery all the way back up to full - and then repeat. Also, make sure you do not charge the battery after it is full. Most phones or charge units have signals to tell you when the battery is fully charged. Do not charge the battery overnight.
These are the best ways to protect the life of a battery.
