Comments on battery life? Is the Lithium Ion battery easily replaceable? Charges with USB?

I don't think there's any easy way to get into this thing to change the battery, but you won't need to think about replacing the battery for a LONG time. Battery life is VERY good on a single charge (about 25 hours), and if you really need to run it longer than that between charges, you can plug it into a car charger or AC with an appropriate "power only" adapter.

Battery life is excellent. Battery cannot be replaced. Charges with a standard USB cable.

Hi, I do not think the battery is replaceable. I have about 250 songs on mine and I charge it about every 8 to 10 days. I only use it at the gym for an hour and a half every day. It does charge with the USB cable. Thanks, Pete

Don't know about battery replacement-never had to. Yes it does recharge via USB.

There is no easy access to replace the batteries. But, as with all devices and tools that use lithium-ion or lithium polymer batteries, they are fantastic for a couple a thousand cycles of charging, minimum. That would mean you can charge them three times a say for several years without a problem. I can't see anyone using them that much. I hope the information helps.

The battery is rechargeable, but it comes with a wall charger where it sits in it. It's not USB Chargeable. It's good to buy an extra battery. Not that expensive. I have this camera and it works very well.

Two questions: is the charger functioning properly? And, is the battery old and no longer able to be charged?

My usage pattern is similar, and I have had no battery life issues. I've had it a month and am still on the original set of batteries, and I will look into rechargeables after that as is my custom. I would strongly suspect that you have a defective unit. Personally, my big complaint is the lack of accessories; especially since it lacks a lanyard, some form of belt holster would be nice, and a rubber grip would be a very sensible addition.

The battery can be replaced by the consumer if they you can use a screwdriver. I bought a standard skill set with the add on tips. Stars, phillips, and straights. The smallest 2 star tips fit all those tiny little screws. It is not hard. I have done it many times. I'm currently swapping out a mother board. And it's not a bad phone. For an android. It runs faster than most. 3 members of my family using them now and we been through about 6 or 7 now in past 3 years. It is a good phone and querkty keyboard a big plus.

Honestly I have never measured the battery life but, for what its worth, quite a bit of times i leave it on accidentally for 2 days or so and it still has enough battery. If youre using it connected to the usb its not going to run out of battery because its getting powered by it.

The one I have uses batteries not sure if using rechargeable batteries the device would recharge them when in USB . Good ? I need to try that! But no if its the same version I have it doesn't have a built in lithium.

The battery is built in, so you don't replace it. It has a USB connector, not unlike your cell phone, which you charge it either via your laptop or with the cord and plug that comes with the unit.

I've only had it for a week, so no battey problems yet. It lasts my whole 10-hour work day on a full charge. There aren't any instructions included abot replacing the battery, but it looks like someone else responded and said it IS user-replaceable.Li-ion should last for years, but good battery maintenance will help extend the life. For at least the first 10 cycles, I charge it fully, then drain it completely. Don't recharge when it drops to 80%, 60%, etc. The performance doesn't suffer at all even when it is almost dead. That should help you get the most life and best performance.

There is an non removable battery in it. Like other lithium batteries (i.e. non removable phone batteries) they have to be charged not replaced. I wasn't to keen on the USB charging as I would rather be able to throw a battery(ies) into the light if it goes dead. I have been pleased with the length of time my light has gone (bright flashing mode). I had an instance where I used it a few days in a row and did not plug it in. THAT was when I wished I could drop a couple batteries in it. After that, I bought a mini USB lighter plug charger. Now I can charge it up in the car BUT it does take awhile to charge so if it's dead it would be kind of pointless if you left the house to ride and only had 10 minutes of driving.

It unit has an internal Lithium battery that you charge with a usb cable. Not replaceable.

Not sure about replacement batteries. I've never had an issue. I just charge it through the USB port on my computer.

The battery on mine can last for about 2 hours with Wi-Fi turned on. There are three different USB slots (one on the side, two in the back).

Batteries are internal ... non-removable as far as I can see. I've used both my computer and a USB wall plug to charge. Holds a charge for at least 2 months. Discharge rate is about 8 hours depending on how much volume you use.

I've had my Lenovo since June and almost exclusively keep it plugged in. I used the battery a couple of times but only for a short period. So, I really can't comment on the battery life. However, I do understand that it's good for only 2 hours or so. I've read other complaints about that. Also, can't comment on the battery replacement issue. Sorry!

I've mostly used it on USB, but from time to time it comes unplugged and I dont notice til days later that it's still running. I've never attempted to use it for 80 continuous hours, but I'd say it lives atleast 60 before it needs a charge.
