You say "simply let your battery deplete to 2%" when I reboot phone, battery is at 50%. So you mean first time phone says 2% not actual battery life?

I normally just allow my phone to get to 2% prior to charging it. I tried at 30% before and the phone seemed to die fast than before. It takes my phone a couple days to reduce to 2%. If it is at 20% I will play games for about an hour so I can throw it on the charger for the night. It does take a few hours to get a good charge on it.

It should hold its charge twice as long as your phone dormant or not, the item may be defective

After I installed the new battery, it already had a charge (I don't remember how much) but it was sufficient to work for a day or so. Then I just put the phone on a charger and it worked fine. I noted that I actually got LONGER battery life from the replacement than I ever had with the original - but that's because it has more mAmp hour storage. So if your battery does not charge up after install, I suspect there may be another issue with the way it was put in.

There Is Absolutely No Need To ReBoot It Two Or Three Times A Day. It Is A Nice Device That Just Needs To Be Powered On Just Once. I Don't Know If It Is A JailBroken Phone, Didn't Know It Was. And Your Right The Operating System Is Different On Here.

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.

I don't know about your particular problem but I received a bad battery. The phone would show 5% and charging and after a few minutes would say it was fully charged but the phone would not boot up. I returned the bad battery and ordered another one from the same vendor. The new battery worked fine. Not sure if this is any help but wanted to share my experience.

I did not. Charged it fully and then used it till less than 7%. I'm averaging 4 days of usage... a mild user (wifi & bluetooth off). Bought a second battery so that I can charge one while the other is being used.

When you plug the phone into the battery it will appear a message saying that the device is not compatible. But once I plug it, it works perfect. It gives me a complete battery charge. I have never tested if it can give me a second charge.

'cause when the phone says 100% the battery is not actually there. the phone only interprets the voltage it senses but the capacity of battery is not full yet. I recommend to only charge the phone with at least 2A charger. suppose you have a 0.7 Ah charger (700mA) (it reads on the charger btw) then 10000mA divided by 700 means 14 hours of charge required! this is why you should always charge with 2A charger, that way over night (cca 6h) your phone will be fully charged.

Not really . I mean it didn't happen to me when mine broke. Phone battery has nothing to do with the phone's memory

This is a tech question and should be answered by the company. "FoundersTelecom.com" I have no way of knowing that. F.Y.I. I just ordered a new battery which was half the price of buying a new phone. It didn't feel like it lasted too long as I rarely use this phone. Caveat emptor, if you haven't bought the phone yet. BTW, sorry it took me so long, but I wasn't sure I could recommend this product or what the problem was with it.

I have had nothing but trouble with battery life on this "monster". I received it as a Christmas present, charged the battery for at least 3 hours initially, then used it for an hour or so. When I tried to use it again the next day, the battery was so low the device would not boot up. Recharged it to 100% capacity, closed it down to sleep mode, tried to use it again after about 24 hours. The battery was again completely discharged. This has happened 3 times. Who wants a device that you have to charge for 3 hours EVERY 24 hours in order to use it 6 - 8 hours?? I don't recommend anyone buying this item!

it says to do 5 full charge/discharge cycles in the beginning. I was only able to do 2 because it takes too long to both discharge completely and then to charge it back up. it lasts 2-3 days abusing the phone.

Once both are charged, it runs off the phones battery power. When your phone gets low, you turn on the battery case and it will charge your phone back to 100 %. Then the battery case turns itself off. I can charge my phone when it's gets down to 2 % and use the case 2 full times before I have to charge the case again.

My phone got pretty poor battery life (maybe 1 day or so) until I turned off the keypad light (menu --&gt; settings --&gt; backlight --&gt; duration to off). Now it gets a few days, not great, but not horrible. Your phone or charger is (or was) certainly defective--10 minutes is ridiculous. Alan

The battery is about 2x thicker than the original battery. That is why they send the new back cover with the purchase of this battery. The original back cover will no longer cover the thickness of the battery. HOWEVER, if you like the phone at all, you will LOVE the additional time the battery gives you. There have been times when I've not used my phone heavily, and been able to go two full days & nights with out recharging. There were times with the original battery that I had trouble making it to the end of the first day... They should have provided a battery of this strenght from the start! I love mine!

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).
