do our SGA hve auto disconnect when charging is full as nokia has?
and is it safe to put our cell for overnight charging?
Yes, as long as you have the factory battery you don't have to worry about overcharging. It will stop charging when it is full, and you do not have to worry about unplugging it.

This is my first post, hope you can understand what happens to my phone (SE X10 mini pro - U20i).
When I connect it to my wall charger, it starts charging normally, no problem. If I charge it overnight, what it is supposed to happen is that it charges to 100%, then it stops automatically the charging process, "waits" untill the battery drops a given percentage, not sure how much, and then charges again, and repeats this process until I disconect the phone. This is the normal process, and usually does this.
But some times, what it does is charging to 100%, stops charging and it remains in the 100%!!! Never drops, and it discharges the battery much more rapidly!! I have System Pannel, and when this happens I see that the processor is allways in the 10%, which is not usual in standby... and as the battery is discharging, the % doenst change, still shows 100%, when it is maybe in the 3800 mV. When I disconnect my phone, the % starts decreasing rapidly, as if it was trying to "compensate", ah in maybe 30/60 minutes reaches 50%... This is not normal, and I think it is some process that stops associating the % of the battery with the voltage.
Ever heard of something like this...? My phone is temporarily rooted with Z4mod, with stock firmware. 2.1
try this:
install xrecovery
make sure your battery is at 100% (let it charge over night)
go into xrecovery (press back while the SE logo appears while booting)
go to "advanced options"
delete battery stats
and drain your battery till your device turns off, doesnt matter how
No go. Doesn't solve it... Going to try to charge it tonight with the background data option turned on. Have it turned off to save battery. Probably won't solve it, but it doesn't hurt to try.
This weekend I've charged it WHILE turned off, during the night. Got it off the charger, symbol in screen appeared with full charge, turned it on, it immediatly shown 18% battery left... This is really weird. Can it have anything to do with not using the original charger? I'm using the original as a travel charger, in my bag, in case I need it at work, and at home I use a Nokia charger, with an output of 890 mA, and with the adapter to microUSB (which actually gets very hot). Do you think it can have anything to do with this issue?
Turn off data traffic and "sync now", you will save battery.
With data traffic and sync on, my phone last just one day ( about 24h ).
With it off, It last about 2 ~ 3 days.
Result: I just turn it on, when is needed.
try turning off data traffic and as ur phone is rooted use SetCpu and auto killer memory optimiser....nd never over charge ur phone....charge it only when the battery is <10% and charge it until it gets completely charged....nd as soon it gets charged disconnect it.....nd set the SetCpu to ondemand and auto killer to optimum...see if that works for u..
lso get ur battery checkd if thats ok...
Hi as stated my question is NOT to know how many of you experience charging that takes too long, but is there a SOLUTION for it?
I am using a desire s, it used to take 2hours 30min(from 15%-100%) but now a days it takes close to 5 hours to fully charge.
I've read many thread with similar problem but non seem to be able to find the solution.
I doubt it is battery related issue as i got this phone together with my friends and theirs has no issue like this.
I've tried :
1)full wipe
2)different rom(s)
3)different kernel
4)battery stat wipe
5)different charger(both are htc)
ps : I've post this in DesireS Q&A but did not get any solution.
How are you charging your phone: USB to PC it via wall charger? If it's taking longer than usual turn off the phone. I've found that this sped up the charge dramatically! By doing so, you can also see a battery simulation on the screen showing the charging process.
Also, if you're charging vis USB, the requirements are 5 volts from a USB connector. But the problem is amperage. Wall chargers can supply up to 1 amp (some will supply more, but you don't want more for a phone), while many computers will only supply 500 milliamps out of a USB connector. Thus the phone (battery) will charge faster with a higher amperage. If that doesn't do any good, you may have a bunk battery or some kind of hardware issue...

I am using wall charger. It seems consistent to charge slower at around 70% then speed back up at 90%. Are u sure that this is a symptoms of a spoiled battery?
To me(an accountant not a technicians) it seems like the "smart" phone is tell it to charge slower at 70%.

Same problem
I have the same problem, first when I bought my SE x10 mini pro. It charged in 1.5 hours but nw it takes about 3 hours. I don't know the reason but I'm trying to find out how to solve this problem.
I'm not entirely certain its a case of bad battery, but it does sound a bit suspicious. If you're feeling up to it, you can try this: (it's worth a shot.)
If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors and re-calibrating the battery along with some steps I will outline for you below will ensure that your battery is getting a full charge, and the battery reporting accuracy is right on.
1. Take the case off your phone (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your phone to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your phone completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Wipe battery stats and reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
The next morning, use your phone as normal throughout the day. Then when it comes time to charge again, see if that does anything for your battery life and/or charging times...

I liked your current charge curve..
bump
ps : i did try out #5 but no success
best way is shut down device when charging
Sent from my GT-I9300 using xda app-developers app
Yes is charges quickly when the phone is off, but what if i am expecting a call or some sort. Could it be a script some where to tell the phone when should it start slow charge or something similar?
when the charge is above 50%, it doesnt auto shutdown but when i play music or surf the internet at below 50%, it automatically shut's down and my batery heat is only 40%(?)and doesn't reboot.Has anybody experienced this?
Hey Addak,
Please provide info about your ROM and kernel, so we can check if there any issue or just suggest another one
Regards

Try some battery calibration, provided by zimmerAndy in Feralab´s Discussion Thread
HOW TO -
1. U need to drain your battery untill it went 0%, it will switch off ur phone for sure lol... than try to turn it on untill it wont even start/vibrate....
2. Now after completely draining your battery...connect it to the charger (To the socket charger not to the computer - we needs to get full voltage)
3. When it become 100%, do not disconnect the phone from socket wait untill 1 to 2 hours....(u can start your phone BUT DON'T USE IT )
3a. if your battery drained till its connected to the charger in 1 to 2 hours disconnect your charger and charge it again untill it gets 100% and repeat it untill battery stops draining on charging. than continue to the step 4.
3b. if your battery is not draining in this 1 to 2 hours, than go with the step 4.
4. Now the phone is fully charged disconnect the charger , reboot into xrecovery and wipe battery stats, reboot your phone, when lights gone off remove battery from the phone, and put it back and power on the phone.
5. leave it on charge and charge it untill 100%, disconnect the charger and reboot the phone, after power on
5a. if your battery percentage is 100% u done with the battery caliberation.
5b. if not than charge it again and reboot and check for the percentage, repeat it untill u get 100% battery on power on.....
From yerstaday my phone doesn't charge when it's on. I must shutdown and then start charge.
Anyone using this battery charging case? Bought one from Amazon a week ago, it works great but there is one problem.
As we know when just charge the phone using any USB C cable. I usually charge it at night when I goto bed, so when it charges the phone up to 100% full and the phone will remain 100% unless I unplug the charger (doesn't matter how many hours or days)
But if I put the Alpatronix battery case on my phone, when I charge it all together (according to the manual , it was programmed to charge my galaxy s8 first then battery case) When my phone reaches 100% it stopped charging and I can see the battery starts draining even though my charge cable still connected. This is what I don't understand. I tested it with straight charging cable and wireless charging. Both end up the same with the Battery case attached. It will charge my phone and the battery case for sure, but it stops charging while my phone reaches 100%. And when it starts draining from 100 to 99 and so on. It will not automatically charge my phone itself till it is full. It will only charge the phone when I am not using battery case. My phone will remain 100% all the time with charge cable connected. No matter how long I have the phone connected to the charger, hrs, days. It will keep it 100%. I wonder what is the main problem? Would it be a defective Alpatronix battery case?
I think it is normal?
I've had many kind of power bank, which is the same principle as battery case. Most of them stopped charging when phone battery is full, and yes, you need to initiate the charging again if the phone battery starts decreasing (usually by pressing the button).
Well, there are several "smart" power banks that starts charging when you plug in the phone, and does trickle charging when the phone is full. But, what I want to say is that not every power bank is made of the same system.

Are you talking about power bank or battery case?
If you know any battery case that has the feature I mentioned above, can you give me the name?
I have a few power banks but I don't like carry it separately. Battery case is more convenient.
