Hmmm....This problem normally occurs when u use duplicate batteries available in the stray market

Please try to get good ones...

1. If u think that u already have the right batteries, please check ur charger unit...try with a similar one in working condition

2. Check the contacts, on the phone and check for all visible damage on the power lines on the board/ phone

3. If within warranty period, i would suggest u take the phone for a good overall checkup

Try to tell me.... whether my suggestion was useful???

Bye

:)

Have a nice day.

The battery life is VERY much shorter on my phone than it used to be. I'm having to buy new ones every 3/4months? What's wrong? I always buy the best possible type from a reliable supplier.


battery life depends on 2 things
the amount of time you spend on the phone and the number of apps you are running
and the level of charge at which you recharge the phone
Recent questions put to a phone repair shop got the answer that 3 days from a fully charged battery was exceptional as most only do 1 day on normal use and less if watching live streaming
as to the level at recharge , batteries have a habit of developing a level memory and will not charge past that point
So if you continually recharge at almost flat, and allow for a full recharge , you get full battery life
at the other end of the period , if you recharge at say 75% charge , the battery memory starts and then it doesn't matter how long you charge the battery for , it will only charge 25% which means you wind up with a flat battery more often
so how to overcome the problem---the more you use it the quicker the battery runs down and when recharging always allow the battery to be less than 5% charge before recharging it ( dead flat is best) and leave it on charge for the max amount of time ( overnight is best)

My batteries don't seem to last more than 4 hrs on my Garmin. Why?


if you are using an automotive unit it shouldn't last longer than that reason being is that you always have a readily available power source.

if you are using a handheld unit (hiking, etc.) with rechargeable batteries then you might need to replace the batteries.

there are a couple of ways to prolong battery life.

1: turn the brightness down in the display settings.
2: turn the volume down of the unit

It only last for 1 hour and a half . according to the store this is normal because my processor is AMD athlon and 2 gig memory. i thought 6 cell batteries run for abt 3 hours. is there a compatible battery...


The lithium iron battery for this conputer is 4000 mA/hrs. or 4 Ampere hours. That means that with a draw of 1 Ampere the computer would be useable off the battery for 4 hours. Since you can't run off the battery below a certain voltage you can deduct 20% leaving a battery life of a little over three hours.

Battery dead, even after recharge. how long should battery last before it must be replaced?


Hi,

the life span of a battery depends on the cell of the life.If the battery is a genuine battery, it can last for about a day because the make of the phone you are using.

An LG phone does not normally have very strong battery life, but at least it can last for a day before recharging it.

The battery of the phone you are using i think the battery cell of the phone is weak that is while it dies so quickly, so it need a replacement.

Take care.

I had been using my Wii fit without any problems until I got (1) a rechargeable battery pack and (2) Wii fit plus. Since then, I don't get very far until the blue light on the balance board starts flashing...


the rechargeable batteries have a rating system, for how long they last.
a battery with 850mHa will last a far shorter time than 1 with 2500mHa rating.
and non rechargeable batteries have a much loger life span than all rechargeables.
Also rechargeables are 1.2 volt instead of 1.5 volt and will aleays run down alot quicker.

Hi! My name is Steve ,and i want you know if its normaly to keep my battery working just 2 days,after then i must recharging


Hi Steve,

Well, it depends on the type of phone as to why your device is only lasting 2 days of battery power.

Your phone, the Nokia N70 is rated to last 3.5 hours of talk time, or 11 days of standby time, meaning if you are not using the phone that's how long the battery will last when the phone is on but the screen is off and you have minimal apps running on your phone.

Which means that you must be using your phone for more than just calling. For most people, they can barely get 2 days of battery real life on this phone, especially if you are a power user.

It is a color screen phone and that is one of the reasons why it uses up battery so much. The other reason is because it is connected to the internet as well.. that draws a lot of battery over just a regular flip phone. Nowadays, people using a smartphone can only get a day's worth of battery life out of their battery. Although, some smartphones can last 2-3 days or longer depending on battery size, how its software regulates drawing/using battery, and the technology inside the phone. The Nokia N70 has a 970 mAh battery compared to the new smartphones with as much as 3000 mAh batteries.
