I have the RAZR and i can only get about 30% extra on a single charge. not much but for the price give me enough to last for the rest of my day.

If this is about the portable charger, ( amazon send me an email ) I have fully charged it and kept it in my car for two weeks before using it to recharge my samsung phone and it not only fully charged it once, but I was able to fully recharge my phone a second time the next day from the same unit. The first time I had neglected to recharge my phone and the battery gave out. The 2nd time from a very low state to full charge in about an hour.

I owned the Motorola atrix and it would charge that well past 75% before dying. I now own the Samsung galaxy s3 and I get a little over 60% when charging the phone from 1%. The device is great when you don't have an outlet nearby and just need to buy time until you can sit you phone down for a period of time and charge it...but to directly answer your question if you charge the portable power pack fully it stays fully charged until you use it to charge another device. I've let it sit for weeks after a full charge, powered it on and it was still fully charged

My experience is that this battery only lasts for 1 charge of my Motorola Droid Razr. I would only use this battery to extend the time on my smartphone, not to charge it up. Hope this helps you!

How long will the the battery charger stay charged after It is fully charged? Like 1 month, 2 months? Will it lose its charge after a prolonged period?

It lasts quite a while. I have been very happy with this charger and would recommend it to anybody.

I haven't left the charger on my RazR past a complete charge. It does completely charger my RazR and about a .25 more on another phone.

It will last for quite a while before you use it as it is basically just a battery itself. It is only enough to charge a phone once though before it needs recharged itself.

On first use, it lasts more than one charge-up. After a few months, now it is good to get my droid X2 from 15% to 80% one time, just to make the day longer. It can't bring back a dead phone.

while operating - at least 6 hours. I think mine died during the 7-8 hours after a full charge. I leave it in my car and the batteries remain charged until I actually use it and I'd say it keeps its charge for awhile, on a monthly basis. Not too sure about annually.

It has an internal battery that needs to be charged, it does hold a charge for over 6 hours, I have had mine run for 10 hours on a single charge.

probably about 3 plus hours -we use it for travel so it is usually being plugged in every night or during use. Never have had a problem with too little battery.

Approximately 7 minutes. It's a small battery but it also doesn't take too long to recharge.

I'm getting a good 8 hours of continuous music playing time from one charge. The standby/off battery life last a long time it doesnt drain at all.

I should add to my previous response that the battery life on a full charge is at least 8 hours.

I would guess several hours, I didn't keep it in constantly after a charge, but using it 20-50 minutes at a time a few times a week, it lasted over a month for me.

I'd say mine lasts just under 3 hours at the lowest power levels. The battery is easy to remove, so you can always buy a second battery to double your life.

So far after I charge the battery it will last about 90 minutes. I have not had any issues with the battery.

Not much I would say... It's a five hours battery but for me (with trainer mode on) last little more than three... I have to recharge every time, because I workout aprox. two hours in the gym everytime. i can not go two times in a row, with one charge...

A very long time. I would say somewhere around 30 hours. The battery lasts forever though.

Maybe30 Days, I don't recall. The battery does not hold a charge very well though.

I've only charged mine once and forgot about it for a couple weeks, I just used it yesterday to type this review and it appeared to be nowhere near empty so I'd say it holds it's charge very well. Back when I used it more frequently I could go two days on a single 4 hour charge.

I have used them for 6.5 hours so far today on one charge. The battery is still going.

It depends on usage. I use mine on a Black and Decker Small hand drill and I manage to get about 4 hours on a charge so I have two batteries.

I use it on the bus to work, my commute is short about 45 min.; the battery last for about 4 days. After using the on, off, volume up/down etc. for a period of time, the printed data dissolve.
