Is charging our Kaisers from the PC ok? How much power does the USB provide to the Kaiser? Same as the standard adapter? I am asking this because I found no answer on the forum and I would prefer to load it directly from the PC every time rather than keep using the standard charger and putting it in the power outlet.
my advice for you to stop this option
because normaly we keep the phone connected to the pc for a long time and it makes the phone in charging mode all the time and iam sure that will make the battery dies fast
stop this option by disabling it from the battery options you can see it by clicking on the battery icon on the start bar
greetings
My phone has been plugged in to the USB at work all day, 5 days a week, for 5 months now. I can still get about 2 days out of the battery when I need to - for instance, after unplugging it each Friday at 5 I usually won't have to charge it until the same time on Sunday, the only time it generally does get plugged into the wall charger. I'm pretty sure my battery performance is still on a par with most people's - ie, not amazing, but quite livable with. It's certainly not showing any signs of harm from overcharging.

Same here.. no problems. I don't even know where my charger is.
I charge mine from the PC all day too, and it stops charging when its at 100%. The bottom line is this: a USB port delivers a minimum of 500ma at 5v, the wall charger is probably very close if not more than that. The charging circuit in the phone does all the work of converting the 5dc into a charging voltage/current required by the battery, usually ramping up and down. Theres no difference other than maximum current between a USB port and ANY 5vdc adapter.
Wall wart gives 5V/1A. USB at 5V/500mA will not harm your battery. If you're using the standard battery, USB charging is appropriate to keep it topped up.

Isn't the constant charging of the batter bad for it?
I mean you charge it use it for a while then hook it up again and so on, isnt it better for the battery if you wait until it says that you have to recharge it?
According to my BatteryStatus, my wall charger gives me around +500-600mA (depending on programs running) and USB 2.0 charging from the front port on my computer gives about +100-300mA (depending on what's plugged into the computer and program usage).

That was a nicad battery issue lithium batteries do not have that issue.
-McMex
i think the point here is not if you charge it by usb or charger
for many people as they said it goes as well ok but it's an old advice used to be known that it's not good for your battery health to be on the charger all the time
also the same fact that it's always better to let the battery goes empty before you recharge it again some people have the sickness of recharging batteries when it's just gets 5 percent less , then they immaditaly start to recharge it again and this is a big mistake because in the long period the first levels of the battery start to die because they have never been used

Actually, its quite the opposite of what you say. If you let Lithium batteries discharge all the way, they will loose their capacity faster.
The following link will back up my claim:
http://batteryuniversity.com/parttwo-34.htm
Relevant quote: "Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns."
usb v wall charger
My kaiser
wall charger charges battery from flat (1%) in 1 hour
USB on PC takes 4 hours to go from 15 to 80%, only over night did it get to 100%.
I use wall charger everyday now.

i use the pc option especially when i am traveling and only have my portable. When using my portable, i plug my phone in to get a charge... i like this option as it saves me from having to lug around another adaptor as well as being able to charge my phone just off the batteries of my portable at any time,,,, good option
posted twice --- as usual being a post hog
It's fine. It just takes longer to charge, especially if you're transferring a lot of data.
With the lithium ion chemistry, it is very detrimental to the battery if you let it run down to empty all the time. The batteries do not like this at all and will exhaust much quicker this way. If you were to store the batteries, you should store them at 40% in a cool place as that would only lose 2% of life per year I believe. At 100% storage, you can lost 20% a year of life. A little reading at that battery university website goes a long way

So what happens when your battery that you leave stored at 100% loses 20% a year and a few years later it hits 40%?

haam1978: You are surely right for NiMh. But I don't know about Li-Ion. Time will tell. For now, I prefer to do it your way: discharge almost completely, BUT NOT TO 0%. Mostly to 5 - 10%. But the problem is that my stupid Windows doesn't report the life of the battery accurately ::- (. I got a Mugen 3000 Mah batt...

100% correct.
On a side note, my kaiser will get fully charged way faster when connected to the wall as opposed to USB. (always connected to a desktop with a real big UPS).
So here's what happened:
I just got my hTC HD7, it had some juice alredy so I played around with it, when the battery got empty, I charged it. But my plug has a on/off switcher. I tripped over it and turned it off. This was the first time I charged the phone. What shall I do? I put the phone back in the box. Shall I get a new battery or charge the phone again? HHHEEELLLPPP!!!!
Just leave it to charge? Accidentally turning off the charger while the phone is charging doesn't do it any damage. I knock the plug loose all the time.

A full charge for the first time can be interruped without issue, lithium-ion batterys do not carry a charge memory unlike older handsets where you did have to give a full charge from the outset.
To get the best life from your battery or spares try to do the following:
Try to keep the handset out of any heated environment (eg; a car on a sunny day with windows closed) as this could stress the battery and decrease the charge life.
Do not use another charger that could stress the battery with over voltage (keeping it plugged in after full charge with the regular charger will not affect the battery) the battery will degrage however if it were allowed to exceed the 4.20V/cell limit.
If storing a spare battery for an extended period of time it is recommended that the charge level is around 40% for optimum lifespan.

first off, thanks for that helpful tip on saving batter power. i just have a question concerning the above mentioned (quote) do computer/laptop usb ports supply the same voltage as the charger that came along with the phone? will it hurt the stock battery if i always use the laptop usb port to charge my phone?
thanks in advance

the first one seems to be the same as the stock battery but the second will surely get you through a day without charging with all phone features on(data,wifi as in everything) or a whole day of heavy calling and sms. but if there are only a select features turned on or on stand by mode roughly it will last you two - two and a half.

Seriously, c´mon guys, if the battery dies, just replace it, charge the battery how you want (partial charge is better for Li-based batteries than a full charge), also, HD7 stops charging the battery once it reaches maximum charge level, so if you keep it on charger, green LED will be on, but no charging is done, this is to prevent stressing the cells (cells are most stressed when on full charge and fully discharged). So no worries here .
So I think i found an issue with this case.
I was at 35% battery on my phone and the case was at 1 light. I plugged in the charger at night hoping to charge both the internal battery and the case to 100% when I woke up. The phone was on charge for about 7 hours, which is more than enough to charge both internal and external battery.
I woke up to the phone battery being at 65% and the Zerolemon with the 4 light blinking.
What I think happened is this: At 4 AM my phone got charged to 100% (this was confirmed in the battery settings) , but because the charge is being relayed/passed through the the zerolemon battery, the zerolemon battery disconnected the charge when the internal battery reached 100% as it is designed to do to avoid overcharging the battery. After the disconnect, the internal battery began to discharge at its normal rate and when I woke up at 730, the battery was at 65%.
I'm not sure why the Zerolemon battery wasn't fully charged with 4 solid lights, isntead the 4th light was blinking.
Can anyone shed some light on this behaviour? If this is normal case, then I don't think I can ever get 100% charge on my battery overnight as the zerolemon will always disconnect the charge when the internal battery reaches 100%?
I don't have this case...But if your phone was discharging at it's "normal rate", and was at 65% when you woke up after it charged to 100%, you have a serious issue.

I've got this case, and haven't had this problem, but I will keep an eye on it. That seems weird. Your battery shouldn't have dropped that much in such a short period of time anyway. Try leaving your phone unplugged overnight without the case on it and see if the battery drains that badly in its own. This would at least let you know if the case is causing the problem or your phone is.

Agreed, I'll do another test tonight without the case to see what the discharge is without the case. I did go through 4 alarm clocks during the 4am to 730am period, but i agree the battery drain is excessive for 3.5 hours of no use other than alarm clocks.
I really hope the case isn't causing any battery drain when its not charging the phone.

I've never let the phone on without a charger overnight, so i have no way of knowing for sure if it was the zerolemon case or normal battery drain even if excessive.
I'll do more tests to find out.
I also have the case, and like the above commenters, I haven't had this problem. My best thought would be that the connection from the case to the phone is faulty, or not totally secure. Maybe take everything apart and reconnect it. Hopefully that does the trick
Hi,
We checked the issue with our engineers. It should be the phone itself which drains the battery . Below is the battery how to work. 1. Plug the battery case with your note 5 in it to wall with original charger 2. cell phone itself will get charged to 100% first(battery meter will show 100%),then it will be switched to charge the external battery until the indication lights are 4 solid lights which proves the external battery is fully charged. 3. After the 2 steps, your cell phone battery meter may drain to 95% or 90% it all depends. Your cell phone will get charged again to 100%. 4. All charging completed.

Tried all above steps. Battery connection is secure, all four lights are solid on. Phone is at 100% then drains during day without the zerolemon battery taking over and charging. I'm about to send it back unless the manufacturer has other suggestions. This should be dead simple..... but I'm not getting a charge.
The Note 5 has a HUGE battery drain issue that is model driven. AT&T note 5 will lose a HUGE amount of battery overnight and this is due to AT&T being the worse coders in the world.
I have the 8500 mah zerolemon battery case. .for me , the charging of the battery case takes a longer time indeed. Close to 15-16 hrs to charge it fully. Not sure if its the same for everyone or this should charge quicker. Would it make a difference that bought this case in USA, and using now in India?

I've had a few Zerolemon cases. Here is how they seem to work:
1. The charging passes through to the phone until the phone's internal battery hits 100 percent.
2. The case starts charging itself, ignoring the phone, until the case is at 100 percent. Depending on how much battery drain you have with your ROM and kernel, this may cause the internal phone battery to drop by 30 percent or even a little bit more.
3. Once the case is at 100 percent battery, it will charge the phone back up to 100 also.
It's not perfect, but it normally charges both my case and phone fully overnight. In cases where both were really close to dead, I've charged them separately and this seems to be quicker. Any microUSB charger is fine for the battery case, since it doesn't support rapid charging anyway.
Also, if you disconnect the charging cable and reconnect it, even for a split second, the case will go back to step 1.
It feels obvious that the case should be able to charge itself and the phone at the same time, but it seems not to be possible. And having used (and hated) a Mophie case that claimed to have that feature, I can tell you that just because the manufacturer claims the case can charge itself while it's also charging the phone, that isn't necessarily true.
Have we found that alarms will cause a problem? Mine will cease all charging at night. trying to figure out. I'll wake up with 20% down on phone(from start of charge) and single light on case blinking. After 6 hours+.
Note5, 8500mA case.
I used to use the case with no problem. The overnight charge was always sufficient for both, phone and zerolemon charge bank. This morning I got 43% and only one light blinking after the overnight charge.
Prior to that I was "playing" with some battery apps, installing, trying, uninstalling. IS IT POSSIBLE that any app can change setting to make zerolemon battery not to be charged or else?
I just noticed that I only get the batterycare message when I charge the phone before bed via a cable. When I charge it overnight wirelessly it does. It have the message (how it will charge to 90% by 9am or whatever). Does this mean batterycare isn't working when we charge wirelessly?
hey... do you know how you got Battery Care to show up? I have my phone for just almost a week now... I charge long overnight before sleep and wake-up around same timing, but still don't have the Battery Care showing up.... I tried toggling off then ON again before sleeping but still doesn't show up... do you know how I should fix this?
I hope it has nothing to do that it's a fast charger right? the standard fast charger that comes with it.....the QC3.0 one..
Thanks

I used an XZ and now use an XZ Premium and have found the Battery Care feature frustrating for the reasons you cite. It only works under fairly narrow conditions. And then it has to "relearn" after a factory reset or firmware flash.
My workaround is plug my phone into a fish aquarium light timer overnight and program it to turn on (begin charging) at a time that results in the phone being at 100% when I wake up. That way the phone doesn't sit on the charger at 100% for hours on end...which is what Battery Care aims to do.
And it works for any phone.
I also use an old Sony Charger from my 2012 Xperia T. It charges really slowly...which results in a lower amount of heat in the battery and hopefully prolongs its lifespan. I don't need fast charging overnight!
I've only been using a wireless charger, "have them all over", since I received the phone and I get the battery care notification when the battery is below 70% otherwise the message doesn't show up.

I don't use Battery Care,just wireless charging, primarily at night, with a table top fan going all night as well.
During workweek usage, I don't even bother topping off nightly, this phone does well between charges to skip a day &/or, just throw it on the charger when I wake up & take it off on my way out the door for the day. I don't worry about having it @ 100%...,50-60% will get me through a 12hr shift w/room to spare.

Are you using the official charger?
Some aftermarket USB C cables can damage your phone or even fry it completely.
If you are using a standard charger, I'm more inclined to say your phone is getting warm because the battery has been charging. If you have hotspot on, that can warm your phone up quite alot too... Basically the more your phone is doing the hotter it can get (Bluetooth/wifi/hotspot etc)
FYI: charging to 80/90% will make your battery last alot longer too, if you plan on keeping it a few years. Charging to 100% is the fastest way to degrade your li-ion battery.
If you are rooted you can limit your charge to 90% but depends if you don't have access to a charger all day you might need that 100%.
Hope that helps.

Yes, using the official charger. I also failed to mention that I have a case on my phone. Not sure if that is contributing to it.
Is it because charging to 100% counts as a full cycle? I will admit that I'm not up to snuff on battery tech and what the best way to preserve the battery long term. From my past understanding, if you take your battery all the way down and then charge it to 100%, then that was a full cycle. More cycles = degraded battery over time.
Not sure if this still holds true for li-ion batteries today.
Edit: My thought here is to leave it on the charger whenever I can, thus minimizing the cycles I put on the battery.

My suggestion is download accubattery, it will tell you your battery temperature and also it calculates the degredation and health of your battery. It will also explain how many cycles of wear you are adding to the phone.
Back in the old days with nickel cadimium batteries you needed to do the whole 0-100 thing, that was good for battery memory... But modern day lithium batteries actually are better being topped off and kept between 20-80% in an ideal world. So deep discharges and high % charges wear out your battery significantly faster... This is why electric cars often limit charge, by doing this they can extend the life of the battery cells quite dramatically.... but if you are upgrading yearly, don't worry about it.
Here is an article that will help you.
EDIT: try charging with and without the case and see if it gets hot, definitely cases can be an insulator. You can monitor temp in accubattery.
https://www.wired.co.uk/article/how-to-improve-battery-life-tips-myths-smartphones
The idea that there is a set number of charging cycles for a particular battery, and every time you charge the phone you use up one of those cycles regardless of how much it charges (ie a 10% charge and a 100% charge both use one charging cycle) isn't how modern cell phone batteries work.
As noted, it is best to not charge your phone to 100%, nor do you want to discharge your battery to 0%. It is best to charge it more frequently for a smaller amount of charge each time as well. So charging a phone 10% ten times is better for the better than charging the battery once for 100%.
Heat is also a huge problem with batteries and the hotter a battery gets, the shorter life expectancy it will have. So definitely look into the issue.
If rooted, there are a couple of Magisk modules that control charging. They usually will automatically pause charging if the battery gets too high of a temp. Once a preset time has passed, it will restore charging again. The idea being that the pause in charging will allow the battery temps to drop. You can also limit the battery max charge to another value other than 100% if you want. 80% max charge is suppose to be the sweet spot for battery longevity, but anything less than 100% is going to add life to your battery.
Just so you know the phone does not charge to 100% or allow you to discharge the battery completely. Your phone just shows that you are at 100% when charged as much as allowed and discharged as much as allowed when you reach 0% charge. The partial charge thing no longer has much of any effect since the phone is doing it for you already but the internet hasn't' caught up to that yet. These chargers do stop charging at full and your phone should not be warm if it's charged but unused. So... are you using while on the charger? That's not a great idea because it's going to kick it into charge over and over. The fellow above was correct about using proper cables, I'm not sure that's much of a problem anymore but there still may be some ringers on Amazon and elsewhere. You could also have something discharging the battery enough to get it to charge continuously or close enough to it to warm the phone up over time, a wake lock can do it for example. Those can keep the phone on charge enough to warm it up.
In general with charging it's going to be best to keep your charging and total cycles down because capacity loss during charging is a real issue due to physical deterioration and transfer of materials in the battery caused during the charge. You would be better served by allowing it to discharge at least somewhat and only charging as needed rather than keeping it plugged in. Since you're at work it should be fairly easy to plan your charging so that you'll be able to get through the day without the constant charge. Not saying wait until it dies and then charge, that would be inconvenient, just that you would get more life if you reduced your charge cycles.
No matter what your phone is getting warm something needs to be addressed if it's doing so when not used but plugged in. The charger should stop for long periods and the phone should be cool after the charge completes.
