Charger/dock that automatically cuts power - Touch HD Accessories

This might be wishing the impossible but I was wondering if there any charger and/or dock on the market that will automatically cut the power when the phone is fully charged.
I know the concept is workable because I've seen a different product that works along the same principles - a trailing socket that completely cuts the power when the load drops.
This could be adapted to suit a phone charger so that when it drops to a trickle, the charger cuts the power completely.
I know it's probably unnecessary but the reason I'm asking is that I know it's not advisable to leave your phone on charge overnight but given how easily the HD chews it way through batteries, having to do so is bound to prove inevitable at some point and I'd like to avoid having to switch off my handset when it does happen (after all, what's the point in having a phone if you can't be contacted on it?).
I suppose the alternative is some sort of program that chimes when the handset is fully charged, so that I'd be woken up and can take it off but I'd rather have a good night's sleep

Why do you think that?
Surely the charging circuit is controlled by the handset, and it stops feeding power to the battery when it is fully charged...

Two parts.
Firstly, whilst there is a charge control circuit in the handset, that's all well and good whilst the handset is off but not so good if it's left on.
If the phone is off, it will charge 'til full then drop to a trickle charge to stay there without damaging the battery. If it's on, it will do the same thing, except when the phone checks in with the network or does anything else that uses the battery, the charge level will drop, the charger will ramp up to full power, hit maximum, drop back down to a trickle and so on - it's just not as good for the battery over time.
Secondly, it's better for the environment.
Since I first posted this, Carphone Warehouse in the UK has released a range of 'eco-chargers' for Nokia, SE and Samsung phones that cut out when the load drops (ie when the phone reaches full charge) and will stay off until the user presses a button on the wall plug.
It's a good idea, if a somewhat-impractical design. Placing the button on the wall plug is a bit stupid IMO.
I was actually using a Motorola wall charger at work recently and it seems it has the same function built-in.
When I checked to see if it was fully-charged, my HD wasn't showing as being connected to a charger, it was just showing a full battery. At first I thought it had been un-plugged it switched off by a colleague but when I checked, it wasn't. So I disconnected the phone and re-connected it and the charger symbol appeared in the bar at the top of the screen but, lo-and-behold, a few minutes later the same thing had happened.

Surely chargers these days are intelligent enough to drop to virtually zero output once the battery has charged and then only supply sufficient to maintain that charge.
It's not like leaving the tap on in the bathtub running overnight and flooding the bathroom.

The vast majority of chargers are capable of trickle charging but I already addressed that in my last post.

[Q] Device Battery Drain

Ok - this is completely nuts. When I place my Photon ON my eee transformer, or my wifes TouchPad, the Photon becomes unresponsive. Pressing and holding the power button does nothing. I have to remove the battery or plug it in. In the past, it would reboot and everything would be fine. Battery would appear to be at the same (or near) charge level.
I would take pains to not place the phone near those devices and I have not had the phone lock up. Today I absentmindedly placed a full charge (near full, unplugged 100% charge @ 12:30pm) and placed the phone onto the transformer @ 1:00pm. I checked @ 1:45 and it was unresponsive. I placed the phone on the charger and it came to life... only now the battery was completely drained!
Has anyone else experienced this? Is there a fix or do I just have to keep my phone from other electrical items?
I recharged the phone it went from <5% charge to 100% in less than 30 minutes, so I guess it didn't totally discharge the battery - something just made it think it was discharged.
All-in-all still a very weird happening.
I'm typing this while my Photon is resting on my Touchpad and it's not freezing. How long does it take for it to become unresponsive?
As stated in the OP - 45 minutes. I did not use it during that time.
I have a rather large electrical box that I place my phone on at work while it charges. I see the same thing happen often. The battery will falsely discharge (not sure how it can discharge faster than a 1A capable rated charger can charge it but whatever) I will come back to my phone later and it will have shutdown and is now in the 'charge mode', the one where say you shut your phone down and then plug in the charger and the 'battery' shows up, and it will often be very low.
Normally I just power the phone back on and unplug it and all is good.

[Q] Will the "main" phone be damaged if you keep it plugged in all the time?

[Q] Will the "main" phone be damaged if you keep it plugged in all the time?
When my new S4 has finished charging I get a message "fully charged - unplug now " or whatever
given this phone needs to be always connected to get the best from the Gear S will it harm it to keep it always plugged into the mains?
thanks
No. The message is just part of green earth initiative to remind you unplug the cell charger when it is done to save energy. The charging circuit already stop the charge before that.
It won't get damaged although it's not healthy for the battery to keep Voltage always that high. When it's fully charged it has around 4,6V, when it's flat it has around 3,5-3,6V (My Note3 as example). But no worries, It's samsung so you can replace the battery after a year or two.
But still it would be nice just to slowly discharge battery in your S4 and then, charge it back again preferably with slow charger (like this one you got with Gear S - 0,7A)
The same reason it's recommended to store batteries (if for longer period) with 40-50% of charge as voltage is not that high. You can observe the same thing with all new devices with batteries. They aren't fully charged
Thanks - thats very helpful & educational - I always wondered why the phones came half-charged
The use case scenario was not to leave the phone plugged in "forever" but to try going completely "master phone free" for maybe a couple of days if that was possible
Thanks for pointing out another obvious reason for persevering with my move away from the iPhone and struggling with the Galaxy/Gear/Tizen/Android ecosystem - you can at least change the battery!
er but maybe not in the Galaxy S6!

*HELP* Phone slowly lose charging power

I have an Infinix Note 2 (X600)that have some charging issues
when i charge the phone i usually need to jiggle the cable a little bit to get the power flowing, but lately it gets much worse. when charging my phone need a lot of time to charge. The charger is not the original phone charger, it's a spare samsung charger i found lying around in the house. its usually works fine up until now. I checked the charging power in ampere app and i found that the charger lose charging power slowly over time. for example the initial charge rate is 900ma , the charge rate slowly decaying -10ma /5-10 second to a point where the charge rate hit 0ma. i could leave the phone overnight but instead of charging the phone it reduce the phone battery instead.
My initial thought that it's because the faulty charging port because i game while charging and janked it fairly often. and ideas of what causes my problem or a fix ?
second question: is charging ports of micro usb android is all the same ? or it's different per phone model, cus im thinking to get the port replaced
Long story short. Use the manufacturer recommend,if not the original.
Yes they will mostly work, but when you take the cost of the device into account....
There should be information on this within the website for the smartphone etc.
Ironically enough, my battery died while I was typing this and I was running a GSAM bat test using always the original charger.
In logics term's, you can always start a car with a much cheaper battery, but when you're taking into account of longevity over quality and anything else you can throw at it, all roads have intersections...
Please email the manufacturer, things not the 90s so you will get better support [emoji12]
In no way am I to be taken seriously at ehm 4am.. and there's the bottom of the barrel answer from my beloved XDA

Playing games and charging question

Hello guys,
I am quite sceptical about gaming and charging simultaneously. I've got 2 cases here:
1) You played for a long time, so your phone needs some juice. Put in charger, keep playing while charging or better to let it charge in peace without any load and continue playing after the battery is full?
EDIT: I found the sollution. Asus claims that battery shall not get too warm when charging and beeing under heavy use due to that they move fast charging stuff from phone into the charging adapter. So this question shall be answered by myself. But still some users advice to let it charge without heavy use.
2) Your battery is full. You want to play games. Keep charger in while playing or rather put it out? I mean that if you let charger in, theoretically the battery should not drain any power, so all power suply provides the plugged charger so the battery is not beeing wore, is it?
THX for all opinions/replies.
I have been playing hard with the phone and had used both cases.
Case 1, you can play and charge at the same time. That is why you have a side port to be able to play in landscape.
Case 2, if the battery is full, keeping the charger connected or not should be irrelevant for operation. Now what happens to the battery, is a completely different matter. Depends on the construction and the actual procedures that Asus has put on the phone to keep the phone running.
On both cases it's not good for battery health
In contrast to laptops which use the direct cable power supply instead of the battery when plugged in, android phones use the battery at all times, so if you connect the charger while also using your phone, the phone will use the battery and an the same time the charger is charging the battery
In other words, you are killing the battery with your own hands because being charged and decharged at the same time is really bad for Li-Ion batteries.
That's why they say first charge your phone up and then use it, and repeat, that is of course if you care about using the device in long term, otherwise, just do whatever you want and you're good for at least a year...

Redmi Note 9S weird Battery Issue

Hello, My phone problem is, whenever i charged my phone to any certain percentage like 80%, 90%, 100%, and unplugged the charger and using the phone, first 5-10 minutes its consume 5-6% battery and first 1 hour of using its consume 10-12%.
This problem happening to all roms including stock rom
So it's not your 'roms'.
Tell me about your fone, how old, and what type of battery?
Does the fone heat up at all when it's draining?
Is there an extra slight BULGE at the back of fone?
I know some charger's, like the iphone chargers, can and do lose their amperage, it's how they sell more charger's, by providing the volts but not the required amps, or in this case, milliamps.
Let me know, and I'll try to help quick as

My phone is 11 months old, and the battery type is Li-ion battery
no heat up while charging and discharging
cant sure is the phone slight BULGE at the back of fone?
By bulge, I mean, does it feel slightly fatter? Bigger? Swollen? can you take battery out, if so, is it neat and tidy, as in, lay battery on a flat surface, it should be flush with where you place it. If it's flat, turn it over, is it still flat?
Have you had any recent updates?

no its not slightly fatter and my phone has glass back panel.....yeah got new updates,but the problem is on every roms
but some custom kernel like etherious and agni kernel...the battery draining normally
So if your battery was getting fat, it would be time to replace it, but due to glass back, you cant tell.
Do you standard charge, or turbo charge?
Back in the 80's, I learnt a fantastic trick, read:
Batteries develop 'memory'. They remember how long they were charged for, in that they kind of copy the previous charge, and dont go further than where the previous charge was halted. Meaning if I'm in a hurry, and pull out fone at 60% charge, next time I plug it in, it MAY see the 60% previously disconnected, as full charge.
For instance, I buy a new battery, when I get it, I dont know how long it sat on the shelf for, as it's charge slowly dissapaited through non-use (yes this happens) while sitting on shelf. So when I get the battery, the first thing I do, is place an electrolytic capacitor (valued around double the voltage of the battery) and place negative of capacitor to negative and positive to positive on battery, the idea being to drain it completely. Once I get no power from battery, I then charge it for 24 hours.
This erases the 'memory' the battery develop's, making it like new from factory. The above is the 80's version of recycling a car battery. But you cant drain the battery, being sealed in your f'n, so try the following:
Grab a usb adapter, say a 4 port (mines a 7 port), and plug your powered on f'n into it, whilst filling the other ports with any other usb devices, the more power they need, the quicker you drain your fone., being the objective.
Do not plug the usb port itself into ANYTHING, and do NOT apply power to the hub.
Leave until nothing lights up plugged into the hub (have a thingy with lights plugged in to see the power drain).
Look for a 3.5mA usb charger, the type used for tablets, the amazon fire tablets charger is ideal for this. Once you have completely drained battery and know nothing else works cause your fone cant supply the other devices any power, plug your f'n into the 3.5 mA (milli-amp) charger, and charge for 48 hours.
This is the electronics engineering method of renewing a battery.
My scource is an old '80's magazine, co-incidently, I'm in same edition called CB magazine, the first ever printed version of how to make a battery like new. I hope this works, cause I dont know the actual fone, but if you do this, you'll have the added advantage of knowing you just 'made' a new battery, and learnt not to buy sealed fones where you cant release the battery to swap it.
As I say, if it's a hardware problem, you'll know after this.
Edit: I know apple mess with the charging cycle to make people buy new iphones, which they do in updates. Your problem MAY actually be this.
Good luck!

So in short You tell me to do that is, i have to connect a usb hub to my phone and discharging all the battery. then i have to charge my phone at least 48 hours/2 days?
Yup. If you take your time, and it's not hardware or update related, you'll be glad you did. At the very least, you make your battery brand new for sure.
Whilst googling, I found some saying some optimisation service wont stop, but hey, it's now down to you to help yourself

don't take me wrong......so the methods u told, really improved li-ion batteries..
and also i dont have any 3.5 ma charger....can i charge my phone on pc usb port
and when charging 48 hours, do i have to turn on the phone or charging with switched off

Yeah it works with EVERY battery made by man, unless it really is DEAD, like no acid to react to the li-ion, shame we cant add water like the car batteries of that time to prolong the battery life lol, back then was poor days, lots of handy finds were found...
I would not recommend the pc/laptop method, because I'm pretty sure those usb ports only provide 50 ma (a quarter of 2.0 mA, note the small ma compared with the 2.0 mA)
Power to pc/laptop end user style is 2.0mA devided by amount of ports.
Any single charger rated 2.5mA or above is what you want, so I use 3.5 mA.
Check old big phone chargers, look at the plug, go for more power than your actual fone charger, which I must ask, is rated at how many mA? I predict 2000ma (2.0mA)
The time (2 days) is to FORCE more power into the previous 'rememberd' memory, literally blowing it's mind lol. After this, you use your standard charger, this is only to fix BATTERY, so then we know if it's hardware or software, cause you did the work and patted yourself on the back lol
Edit: keep fone off while charging, just use another old one or borrow one till the charge is complete. By cheating you only cheat yourself lol. By doing, you WIN.

my phone charger is 18watt fast charger....than how many ma it has....and how many watts in 3.5ma charger??
Glad you asked. Your charger is a 2.3 AMP or 2.300mA like I said, try a larger charger
Look at charger till you get what I'm saying re: ma, mA or Amps (A)
2.0 AMP is 2000mA
To make it easy for you. 2.0 ma (how it's sometimes written) is = to 2000mA or 2.0 AMPS, but do NOT make the mistake of using 2000 AMPS lol, I'll hear you from here...
Electronics is defo not software and I forget sometimes i'm dealing in milliamps and amps, etc rather than megawatss from my radios lol
So you will look for a plug that MAY show EITHER 2000mA or or 2.0 AMPS. The old way to write milliamps were once similar, so ma was made mA to show amps. Keep my age in mind lol
