HelloI have not had that problem with this product, but i have not left the battery off for more than 3 days so far. Battery was still fully charged. This case works great. I have enjoyed having it

I returned my Rokit Boost after 3 weeks - it stopped charging. I finally settled on the Unu and it works very swell. It charges with no problem, keeps my phone charged for 18 hours. I love it. Trust me, I've tried several, including the Rokit, and this is the best case I've ever had. It's been 10 weeks and it is still going strong.

The charger is guaranteed for one year. Just email the Seller if you have a problem. It will completely charge a dead/dying phone if the phone is not in use. If the phone is being used with multiple applications it will prolong the time you may use the phone. Great product with very safe Samsung battery that will not be dangerous as many of these products can be.

I guess you have to define completely dead. Will it charge a battery that has been completely drained overnight by leaving an accessory on? Yes, matter of fact it has a automatic De-calcify mode that helps make batteries last longer. Will it charge an 8 year old battery that died because of below zero temps? no, no battery charger will.

I just had an issue with mine not charging. It got to zero and when I rebooted with it plug into the USB charger, I could see the little lighting bolt on the battery indicating it was trying to charge, but it shut off because of low batter. Kind of a Catch-22. I tried this cycle a few times and was fed up, so I decided to unplug it and let it 'die down' for half a day. Then I plugged it back in and the screen showed me that it was charging! I let it charge up for a few hours and it started up and continued to charge. If you are having charging issues, try letting it run out and "die", then plug it in. Worked for me, YMMV. I just had an issue with mine not charging.

Yes, when I am not using it, I do leave it on the charger. I tried not putting it on the charger for a while, but it doesn't have as much power as when I leave it on.

I think it holds up to two "full" iPhone charges when the case itself is fully charged. If you do not use the case's charge feature because your battery lasted you the whole day, then it won't need to be charged at all. Regardless, the case is charged at the same time as your plug your phone is because they are connected.

Kenneth, I didn't know this was still an issue, in 2013. I let my notebook discharge completely, on a fairly regular basis, every few weeks in order to spring the battery. That seems to do the trick by default. But (although I've never tried this) I did find these instructions from Samsung. http://www.samsung.com/us/support/supportOwnersHowToGuidePopup.do?howto_guide_seq=2500&prd_ia_cd=N0000137&map_seq=21605 The larger question, to me (and one I've forgotten about until you brought this up) is what happens when the battery in this Samsung dies? It is built into the computer and can't simply be unplugged and a new one plugged in. Can a new battery be installed by opening the case? Or is this computer "throw-away"? That's one of the many reasons that I archive my work. Sooner or Later....

You will need to charge it every day. I put mine on around 12am when I get in bed and I'm not sure when the battery dies, I'm asleep when it happens but with heavy use you will need to charge more frequently I plug them in every time I use them and they're always ready to go when I am, they charge fairly quickly IMO

I have the same situation. The device powers off on its own, but, yes, the lighter port will still send out power. Your battery won't die from it but it may reduce the life of your battery, perhaps. I don't charge the Brightplay unless it's dead. Otherwise, I use the charger for my phone.

Yes, I leave mine off until I get down to about 20-30% power on until recharged to 100%. I'll turn it back off and I can do that 2-3 times per case charge, unless I forget to turn it back off when recharging the phone. Be aware that it does get warm to the touch when charging the phone, not too hot but you know it's on. Also make sure your lighting plug port is clean as if it traps dirt or anything it can scratch the connections and cause issues with the phone. Otherwise highly recommended.

i believe the charger turns off automaticly after the battery is charged at least some do tho some chargers tell you that you are useing unnecesary electricity by leaving it on but i would suggest removeing the battery once it is charged.

Your question doesnt make any sense. The case is not the battery so the case does not charge. You can charge the battery on or off the phone in or out of the case.I have no idea what these other 2 people are talking about in their answers.

Yes, when you insert your phone into the case there is a connector in the case that plugs into your phone. The case has a rechargeable battery built in that will provide a full charge to your phone. You can leave the phone in the case and when you charge the case it will also charge the phone. It's basically a spare battery built into the case. I'm very happy with mine!

I've heard that constant drains on the battery can be hard on it, which I find somewhat contradictory (clock, radio saves, etc) but still feel there may be some merit to. I've only used my always-on 12v supply in my car twice, when my phone was important but completely dead.If the camera doesn't have a Charge light, your phone charger should (or at the very least, your phone should show whether it's charging on the screen or not). I'd use that to see if it's switched, requiring the On position (or, perhaps on some models, Accessory), or constant.

We advise our end users to turn on the case when the phone battery is down to 20% to have the most usage of the case. If you leave the case on all the time, you will receive less battery because there is a constant conversion going on between the case and the phone which leads to more energy loss.We hope this helps! If you have any other questions, please kindly contact us via services@myunu.com.

The answer is yes.Your phone is designed with software that never allows a full charge technically. Batteries last much longer if they are never fully emptied or never fully charged. When you see 100% on your battery icon it is really more like 90%. The software essentially "turns off" the charging even when the phone is still plugged in (like overnight for example).

Depends. If the device is powered off it will almost always charge (slowly). If it's turned on it might either charge *very* slowly, or not at all, or even still lose charge if you're actually using the device. (You'll see the latter with high-end phones or tablets if you are running a 3D-rendered game -- the device will be using more power than any USB charger can safely deliver, so the battery will slowly drain even if it's plugged in. With a crappy charger this can happen even if the device isn't doing much.)
