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.
Bought this tablet yesterday after finding it for a €50 discount and reading some reviews. The reviews warned that the charger is a but underpowered, and they weren't kidding, after 15 minutes of being plugged it I've only seen it go up 3-4%. Worse yet, if I try to actively use the device (just some browsing, nothing intensive), the charger can't keep up at all and the battery charge starts dropping again, slowly.
I'm quite happy with this tablet, it's got a nice feature set, good performance, decent price; I don't want to return it. But not being able to use the device when the charge gets low is a bit of a deal breaker. So I'm left wondering.. is there a way to charge it quicker? Would a 3rd party charger with higher amp output work? Or doesn't it work that way?
be sure being charging with original charger and usb cable
I was having same issue during the first month with this device, i was charging it with another usb cable (much longer) else than the OEM one, My device took 10 to 12 hours to do a full charge, very annoying thing. After some thinking and asking other ppl about this issue, tried to charge xtz with the charger and usb cable included in the Box and voila, not only the charging time has reduced to no more than 3 hours, right now i can use the Tablet without no intensive power requierements (wifi browsing with minimun screen intensity) and can see how the charging state increase during use... Hope this can help u.
Thanks for the reply! Sadly I'm currently already using the standard USB cable and charger that came with it, but maybe my cable is just fault or something. As far as charging rate goes, 3 hours sounds like what I'm getting, so maybe my expectations are a bit high in that regard. On the other hand it seems like I should be able to at least use the device when it's plugged into the charger without running out of battery charge (even if much slower). Almost seems like it's just being drained abnormally fast, but according to the battery usage thing, ~90% is used by my display which I guess is normal
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
