About Battery Charging

In tp2 will the battery be still charging after the LED indicator shows green.. cause i have heard that overcharging can reduce the battery performance .. is it true.. all i wanted to know is can i leave my phone for charging while i goto sleep or i should remove the plug once LED glows green??

LiPo batteries tend to catch fire if you overcharge them. Well actually there are safety measurements in place now so that doesn't happen, they'll just get fat and vent gas instead.
Since your battery has not caught fire or vented you should be fine. Charging circuits are intelligent with these batteries, they have to be.
Also, there is no need to fully drain the battery either. Memory charging is a thing of the past.

A green light indicates a full charge and the device stop charging.

[Q] battery question

I feel that my phone seems to charge a lot faster when it is turned on than when it is turned off. I heard that having the phone on when charging is bad for the battery because of parasitic charging.
I read on the Sony support site that leaving the phone charging for an extended period of time won't affect the battery and charging often won't affect the battery's lifespan, which contradicts what I've read about li-ion batteries in general.
So basically my question is: is what the Sony website says true and is parasitic charging really that bad or a difference-maker in terms of battery health because it is annoying feeling pressured to turn off phone when charging.

No my frnd, these things dont affect our phone. U DO NOT NEED TO TURN UR PHONE OFF for charging. Sony ppl r right, li-ion batteries r not affected by parasitic thingy. Most probably, u have read/heard wrong.

[Q] what happen to battery after it is fully charged??!!

Hello.. this might sound alittle bit old question or maybe repeated alot but i couldn't find the answer at the internet..
i held two samsung galaxy note 1 and 4, and i noticed when the battery fully charged i can't see that charging mark on the battery.. WHAT DOES THAT SUPPOSED TO MEAN?
does that mean the system stopped charging the battery and it won't affect on its lifespan? or it is overcharging?
i noticed in Sony Z3 there is option for night charging which is when the battery is full it will automatically disconnect the charging, is that thing the same in samsung but without any option or it can damage the battery because it keep charging??
i hope i can get the answer....
thank you

With the stock charger, or any decent 3rd party charger, it will stop charging when the battery is full and begin again when needed.

It goes off full charge and goes into trickle charge. The phone won't turn off the charger when it's full.

Ive always wondered about the trikle charge effect on phones as well as laptops. So wouldnt that damage the battery overtime? Continually discharging a tiny bit and recharging over and over again?
I wish there was a definitive answer to this any many other perpetual questions regarding the current crop of Li-ion batteries..

It's supposedly less damaging to top of a lithium ion battery than to fully discharge and charge.

Wireless charger

So I got recently my free wireless fast charger and really like it but I have a question.
Is there a way to prevent the phone from getting charged when it's at 100%?
I want the charger to stop charging as soon it reaches a certain threshold.

It does stop charging at 100% otherwise the battery would explode

Question regarding Fast Charging feature

Does fast charging as opposed to normal charging (FC turned off in device care) as our standard means of charging our devices affect battery lifespan in the long run?

All things being equal, I don't think that it does

Well, thanks. But it's the noticeable heat generated from fast charging that gives me some concerns whereas in normal charging, the heat isn't that much.

Well, no such differences with chargers I use but if there was I would be probably use normal charging

No. Charging doesn't harm your phone

Its a known fact that high temperatures are bad for lithium ion batteries, fast charging generates more heat than std charging, if there are no adverse effects by fast charging, then it would not be an option, it would be the standard

Fast charging is fine as long as you control the heat; brief 10-30% partial charges generate a modest temp increase. LIs are designed for fast charging.
If your ambient room temp is high simply wrap a damp rag around the phone while charging to cool it.
Monitor bat temp and keep it belong 95 F.
-Avoid full or near full charging-
60-70% is a good range; > 62% is ideal for longevity.
Avoid discharging below about 20%; low voltage isn't as efficiently converted and there's a knee in LI's power curve near that mark; battery % drops more rapidly from 20-6%.
Deep cycle recharges stress the LI much more than short 10 or 20% bursts.
LI's love frequent, short charge cycles in the 40-60% range.
Keep battery >100 F when using, charging or storing!
Avoid using the phone whilst charging; it screws up the charge cycle curve and greatly slows charging!
Same-same if battery temp exceeds 100 F!
25 w brick yields about 2%@ minute charge.
