This is puzzling. I got the Samsung Galaxy S8+ ZeroLemon 8500 mAh battery. Verizon FWIW. I plugged the phone in it and charged the phone via the extended battery port. The phone charged to 100% overnight (I kept on the charger for 7 hours).
When I removed the phone off the charger, I ran it to 1% in 11 hours. I was under the impression that I should have gotten much better runtime than that, based on my experience with multiple ZeroLemon devices. At least 24 hours. And that 11 hours did not get a lot of screen time.
When I removed the phone from the ZeroLemon 8500 cell, it did not appear to have been used, all of the 4 lights still light up, indicating it is full. I was not sure how to pull the voltage off of it. But if it got drained, none of the lights would light up, correct? If it's full after a day of usage, the phone shuts down getting drained to 3500 mAh or so without accessing the external ZeroLemon battery, why? Where is the disconnect? Could it be somehow it did not get fully charged over 7 hours? If so, why are the lights on?
could it be that the 8500 mAh cell only got charged half-way or a third of the way there, which makes the 11 hour figure plausible. I know the phone cannot get 11 hours off the stock 3500mAh cell, it's lucky to get 6 to 8 hours.. 3500 mAh is completely inadequate for a 2960x1440 resolution device so the increased resolution drains it that much faster.
The external ZeroLemon battery has to be turned on. Unlike many internal ZL batteries I've had over the years. I assumed it was the same thing. You have to push the button.

I want to make the most out of my galaxy tablet 10.1 battery life, i was wondering what would be the best care for it. Each 1% for me lasts about 4 and half minutes on 40% brightness, wifi on, gps off, and auto rotation off. I heard the g.tab gets close to 9 hours of battery life, but I estimate mine about 7.5ish? Also, would it be best to completely drain the battery and then recharge to 100? I heard its not good for lithium battery to drain completely and recharge because it will put more wear to it. Any suggestions?
Thanks
There are many theories but the following is what i follow.
It's not a good idea to discharge below 20%.
Lithium batteries don't like to be stored fully charged for long persiods of time, lithium battery is most happy at nominal voltage, so it's not a good idea to leave your device connected to charger if not needed.
I seem to get 1hour of display on use for 10% of battery, this is with minimum screen brightness.
Having read up about this I have decided to charge mine every night no matter what the charge. A typical day use can leave me with 40 percent to 80 percent left. I discovered that a charge cycle is not the same as a charge. A cycle means 100 percent of the charge stored being taken off and put on the battery. So if you use 20% a day and charge each night that is 1 cycle in 5 days not 5 cycles. There is no reason to avoid plugging it in as you dont want the charge to drop too low or else the battery is lessened very slightly.
I am sure there are lots of opinions on this but am happy with the above and battery performance is great. I was worried about unnecessary charging but that is not the thing to worry about - do anything you can to keep it over 20% (although a near total discharge every month would be good to keep the calibration in check).
Don't stress about it too much. Just enjoy the device. With sensible use your tab will he long replaced and discarded before the battery fails.

^^^ my thoughts exactly. By the time the battery fails to hold a charge, the device will be far out dated...
Bought the N4 and charged it full when it arrived without any battery charge. Charging icon showed full (I tap the power button when charging the phone while off to see the charging icon). Put the phone back in the box and pulled it out a few days later after getting a new sim and the battery was dead again...odd. Charged the phone again, turned it on, inserted new temporary sim card, and battery lasted 11 days with very minimal use, but it blew me away that a battery could last that long. When it dies completely, I put phone on charger and saw the battery icon, again, when phone is off and tapping power button, showed full. Unplugged phone but left off. Turned on again 2-3 days later and the battery showed dead. I realized I was using my Galaxy Nexus carger the 2 times it did not hold a charge and thought okay, this phone must require the actual specific charger that comes with the phone. So, charged with the original charger while phone was off and unplugged when charge icon showed full. Turned it on a day and a half later and the battery is at 50%. What is going on? I know I charged with original charger and I saw the icon showing full as the battery was completely lit. Could the battery be discharging while it is off, will the Galaxy Nexus charger not charge the N4, or is the charge icon all wrong and showing full when it is not. Puzzled?
Thanks for any help.

Some components on the board still draw a minimal amount of power while the device is off. If you have a phone with a removable battery, turn it off and leave the battery in. Check it in a week and you'll see significant drain. Pull that same battery out and leave it on a shelf for a week. It MIGHT move by 1%, as long as take battery is healthy.

Thanks for the reply. I agree with what you stated in that the battery may get a minimal draw from a device when off; however, after charging with the proper charger this last time and charging to full, and to see only 47% of the battery capacity remaining after being completly off for 1.5 days is excessive battery drain. Especially since it took 11 days to run the battery down when it was charged completely before.
I don't think that the minimal drain on the battery could run it down 53% in 1.5 days.
Thanks.

That is pretty crazy. I can't test for you myself to give a comparison because I can't leave this phone for a couple of days since it's my main device. Perhaps someone else will volunteer? Anyone?!
have you tried charging through your computer via usb connection? my findings with computer charging this phone is that it is deathly slow compared to one that charges properly through an outlet, but it might be another senerio to add to your predicament.
Hi I have G2 Korean version with removable 2600mah battery which is lower than the int'l version with 3000mah. I've use it for 2 months now until last week when it's the first time I forget to unplug it before I sleep so it was charged overnight. Then at noon time, the phone suddenly shut down with very thin lines. So I quickly charge it but there is a blinking red light. After an hour of plugging and out, thankfully, it charged properly but now I'm only getting 12 hours battery on light usage. I've heared that the non-removable 3000mah gets 19 hours battery, is this true? What's the normal battery life of the 2600mah? Should I get 16 hours (2600mahx19hr/3000mah)?
Did something gone wrong? Any recommendations? I still have warranty. I tried calibrating my battery by draining in and charging it fully while off , calibrating by software (Battery HD) and charging after 30 mins of usage of a fully charge battery (jump starting). Please note that same thing happened on the other battery which also charged overnight on the external charger pack.
Thanks.

Any link for rooting the korean version and any free app for freezing apps?

I know there is already information on this topic ..... I have read conflicting advice on how to charge cell phone batteries, but I want to make sure and get the maximum use and life from the ZeroLemon 10000 Extended Battery for my Note 3 .....
The directions from the company simply state to give six full charges, but there is no explanation exactly what that means. I have sent the company a question regarding this issue, but still have not yet received an answer .....
I just finished the third full charge. When I received the battery, I charged it for 12 hours before unplugging from the charger. Then allowed my Note 3 to go completely dead (to Zero %). Then charged again for 12 hours. Did this three times so far.
I'm only getting around 37 hours of medium to heavy use, or about 1 1/2 days, and around 18-20 hours of Screen On Time, which seems somewhat impressive!
After I go through six charging cycles, should I always charge for 12 hours, or is this no longer necessary?

Based on what I read in charging lithium ion batteries ( which I also practice ), you don't wait until battery discharges to 0 before charging it since it shortens the life span of the battery by damaging the negative electrode. The recommendation is to charge it once it reaches 10% and don't have to fully charge battery to 100%, just around 90 - 95%. Since lithium ion batteries don't have memory effect, partial charges and discharges don't have negative effect on the overall battery life.
Didn't made this up, just quoting from memory.
Never let my stock note 3 battery go below 5 percent. I am getting great battery life. The same with my old i9100.
