Maybe it's tip to improve weak battery

Hi guys ,
After having the new battery , I try to charge the old weak battery with the external charger overnight , then use it , I notice that the power meter going down little after a day use , specifically 90% level whereas in the past I used my PDA to charge it , the power level always drop down to 55% at the end of the day . Perhaps the internal power charger of the Exec is malfunction after long period usage . From now on , I will use the external to charge the battery for my Exec .
Does anyone out there have the external charger and pls try my experimental .
Regards .

maybe the external drains the battery fully before charging it? Doing this helps keep the battery conditioned in tip-top condition. I don't have time for this and always top up as I only have the jasjar mains adapter but I used to try to leave backlight on in weekend and fully drain battery before charging it

...yes with Ni-Cd batteries of 10 years ago but the worst thing to do with a Li-ion battery

i know you can wreck your li-ion battery by going to 0%
but isn't there a safe minimum you should really discharge to?

There is NO point to discharge Li-ion batteries. That is why it has been developed. We wanted a battery we don't want to wait draining it more like to charge it anytime. So, the truth is not "we don't need to drain it" but "we must not to do it", because battery dies in a short time.

[Q] Battery Levels on 2400MAH Extended Battery

I got an extended 2400mah battery from ebay (they are very cheap !) and i gave it a visual inspection, they seem very well built and so far run very nice and cool in the phone.
The only issue is the linux android kernels are reporting it as a "standard" battery !?
I have done the proper rm /data/system/batterystats.bin and then shutdown and fully charge the battery with phone off and then boot up so set the "top barrier" so i can charge correctly in android, but how am i supposed to get a reliable discharge reading ?
i have hammered my phone all day and im down to 15% now, but the battery voltage is still up at 3.795
according to the LI-ION battery discharge curve 3.8 = around 50% battery life still available.
Am i really at 15% ?
-Edit
LOL !!! i read on another thread that someone shut down the phone and remove the battery, then put it back in and load back up and got another 50%, i just tried this and now i have 70%.
Hilarius !

What did you have to edit to get Android to do proper readings on the extended battery?
i charge my batter to 100% then leave the charger connected for another 4 hours. when i unplug, my battery reads 100% for about 3-4 hours then its starts to discharge....
how do i match the level of the battery with the android readings?

Battery calibration

Is there a need for battery calibration ? If say some percentage ranges the battery drops reasonably and at certain percentages the battery just dives. If so how do I do that?

No need to calibrate your battery (ITS A LITHIUM-ION BATTERY), use it as you normally would. Enjoy it till the Note 5 comes out.
But if you want to extend the lifespan in your battery (don't confuse with everyday everyday life), a complete discharge once in a while is still recommended.

I've just recent purchased a official Samsung spare battery for my N910C. I charged it fully after I received it in the mall. But when I used it for the first time today it said that it had only a 80% charge despite the fact that I charged it fully when I received it in the mall. I did some research online and found a couple of methods on how I could calibrate the battery without having to root my device. But I'm not sure which method is the best.
The 1st is:
To drain the battery fully.
Then plug it in and charge it again.
Then drain fully again and charged it fully.
The 2nd is to:
Drain the battery fully.
Turn it on and off.
Then plug it in to charge.
Once the LED or display says it's fully charged, unplug it.
Power my device back on, which will stated that the battery not fully charged.
Plug it back into the charger and let it fully charge.
Then reboot it to check if it's full charged.
If it's not repeat the previous couple of steps again
Does anybody know which of these is the best method for calibrating the battery of a Note 4?

Extended Battery with 5600mah not reccognised

Hello,
I've bought an extended Battery for my GT-I9505.
My Problem:
I don't feel anything of the power increase from the new battery... It's still discharging between 8-10 hours like the Stock one.
I deleted the batterystats.bin,
I calibrated the battery,
I charged and discharged it completly several times,
After a quick research I got the Information, that I need another Kernel, becouse the Stock one don't accept the bigger battery (the kernel think the battery is full charged but the battery isn't really.)
And if I combine 1 and 1 my thought is:
The more the battery is charged, the more the output voltage.
The Mobile recognise if the battery is full to avoid an overloading.
This recognise is taken from the output Voltage exact like the percent scale.
When the Stock battery reached his 2600mah capacity the output voltage is for example 4.000 Volt.
2600 mah --> 4.000 Volt --> 100%
BUT HERE IS THE PROBLEM:
As soon as the 4.000 Volt ≙ 2600mah are reached with the new 5600mah battery the mobile thinks its full charged to protect from an overload.
And I think, that the Battery isn't really full even if the mobile says that.
Can anyone help me?

I'm don't think this is the case. I'm pretty sure there are people using extended batteries on stock ROMs.
Could it just be that the capacity is fake?

Not really... The battery has good ratings on ebay

Nexus 6P - Reporting 100% charge prematurely?

I recently bought a used Huawei Nexus 6P on Swappa. It looks and works great, with one exception: When I quick-charged it (with its OEM quick charger) to 100%, AccuBattery reported:
Battery health: 27%
Estimated capacity: 940 mAh
Design capacity: 3,450 mAh
{From these numbers, it seems that Battery health = Estimated capacity / Design capacity}
By itself, that would make me think that it just needs a new battery. However, if after reaching 100% charge, I leave it plugged in, the "Estimated capacity" continues to rise for a period of time. (The charge stays at 100%, but the Battery health sometimes increases.) Once, the "Estimated capacity" rose to over 2,000 mAh before it stopped rising. This makes me think that the problem might be with the battery calibration, rather than with the battery itself.
If I use the phone until it shuts off, and then recharge it, the same thing happens again (although with different numbers).
How can I tell whether the problem is with the battery itself, the battery calibration, or the phone's charging system (on the motherboard?)?
To recalibrate the battery, should I stop charging it when it reaches 100%, or when its AccuBattery reported Estimated capacity stops rising, or ...?
Thanks.
