Re: battery life under 5 hours

Have you let the battery go totally flat as this is recomended to do every couple of months because if you dont let the battery go totally flat this stops the battery from full recharging and will cause bad cells in the batt so i would let hte battery totally flat till it wont even light phone up then fully charge for 16 hours see if this improves the battery if not then the charger is probably over heating and cutting off so you could replace the charge hope this is some help to you

I put my Droid Razr on charger but battery symbol comes on with ? mark. Won't charge or turn on.

1. Turn off your phone when it's not in use. If you're not using your Verizon Wireless Razr, then shut it off. Your battery will last much longer if you regularly do this.
2. Charge your phone less. If you charge your Razr nightly, then your cell phone battery won't last long. Try to charge your phone only a few times a week to extend the battery life.
3. Keep your Bluetooth turned off when you're not using it. Applications, like Bluetooth, are notorious for sucking the power from a cell phone battery.
4. Protect your Razr from extreme temperatures. Your cell phone battery lasts longer if kept at room temperature.
5. Discharge the Razr fully. Before you charge your phone, let it completely die. You can extend the life of the battery by regularly discharging and then fully charging it.
6. Leave the battery in the phone. Keep the Razr battery dry and free of dirt to prolong its life.

My battery only lasts about 1 hour

There are many standard techniques to improve your battery life. Turn off bluetooth + wifi. Close unused programs. Change your screen brightness to lower levels. Disable location services when not using GPS.
If these don't improve your battery life then its time to change your battery. Also make sure you are using the right original charger to charge your battery.

Iphone 3g proper charging

Once you purchase the iphone,dont use it yet.Instead of using it right away,kindly charge your IPhone with the wall charger for 3 hrs.Please dont use the Iphone while charging.Kindly check always if the battery is full.Once its fully charged then that's the time that you can use the iPhone. Once fully charged, let the iPhone's battery fully drain.Please keep the iPhone off for 2 hours.Fully charge your iPhone and allow the battery to rest in the fully charged state for two hours. (You may use your iPhone during this time as long as the iPhone is plugged in).Repeat the third and fourth step a maximum of three times if you feel your battery indicator is inaccurate.

Here are some tips for your everyday charging for your IPhone:
#1 - Charge your iPhone throughout the day when available. Charge EVERY night, regardless of charge level. This will keep your battery active, which is healthy for the iPhone's battery.
#2 - Use a wall charger or car charger w/ rated output 5V 1A. Computer chargers might not charge when the computer is in standby mode.
#3 - You cannot overcharge your iPhone. You don't need to disconnect the iPhone from the charger after it's done charging. Once fully charged, the iPhone will run strictly off of AC power and will not damage the battery.
#4 - Every two months, make sure you fully charge and fully drain the battery, in one cycle. This calibrates your battery indicator. If you fail to do this, your indicator will become inaccurate. Calibrating your battery does not improve battery life.
#5 - If you ever need to store your iPhone for any reason, make sure your battery is stored @ roughly 50% and in a cool environment.
#6 - Always charge your iPhone out of its case (assuming you can easily remove the case). Charging your iPhone inside your case will make the iPhone hotter, which is bad for the battery.
#7 - Charge your iPhone in a cool location. Charging your iPhone in a cool environment has a tremendous impact on your battery's lifespan. The colder the location you use to charge, the more charging cycles you can complete without your battery deteriorating. Avoid charging in direct sunlight.
#8 - Use properly rated chargers. Using chargers that are not properly rated will have a huge impact on your battery's lifespan. Make sure your car charger has the same rating as the official Apple charger.
The official Apple wall charger is rated as follows:
Input: 100 240V ~ 50/60 Hz 1.0A
Output: 5V 1A

My phone wont turn on or charge even tho i charged it all night

It sounds like you need to replace your battery. But first, if you're using a home charger, try charging the phone with a car charger (or vice versa). If the problem is not with your charger, then replace your battery.

When you get your new battery:
1) Make sure you are using the proper charger for your phone (not one of the cheep $5 kind), and
2) charge your battery for at least 12 hours before you use it for the first time.

Nokia 1100 phone when i connect the charger only i can swith on my phone other wise i cant swith on the phone


The problem with your phone is battery, the battery on your phone can no longer hold charges, that is why it switches on when you connect the charger.

I would advice you get a new battery on your phone and make sure you charge the new battery for at least 4-5 hours before you start using it. doing this will solve the problem on your phone and charging the battery before usage will help preserve the life span of the battery.

Take care.

Well, the white to pink dot is a sign of water in the phone. It is a moisture indicator and the first thing the repair fols look for so they can deny any claims.

They second thing is you can get an external battery charger for the razor. They run about 5 dollars and allow you to charge the battery seperate from the phone.

Battery not holding a you leave phone on while charging

firstly the battery from new will need charging for about 8 hours to boost it after that it should reach full charge in about 1 hour it will charge if it is on or off and when off should show a charging bar how ever there is no way it will recognise when fully charged so dont leave over night otherwise it will reduce battery life greatly

Motorola razr v3m battery problems and bootloader ini showing on screen

Well it is both. It should only ever say bootloader when it is plugged in to a PST machine and getting the software updated. I would say that it the hardware is causing the poor battery life or a combo of the battery and the phone.
