Charge questions.

H, I just got the x10a. I have some questions about the process of charging the phone.
With my last 2 phones, an k850 and a xperia x1a i learned to charge the phone every night. I arrived at home, plugged the phones to their chargers , sleep. Wake up, went to work at 7, battery was at 100% every morning.
Now with the x10a, i arrive at home, battery is almost at 40% aprox, plug the phone to the charger, and go to sleep, wake up at the same time and battery is always at 60~70%, with the cable and back of phone running hot. Yesterday went to see the phone status at 11pm, battery was at 90%, went to sleep, wake up at 4am checked the phone and battery was at 52%, so instead of charging, was discharging, is this normal behavior? I removed the battery and put it on again and the charge jumped to 85%.
All of this is normal?

Kind of if it's new, cycle the battery a few times and it should sort itself out.
Yeah the same thing happens to me. I checked juice plotter and at 2:30 am, I'm fully charged then at 5:00 am, I'm at 70 percent. The it repeats the cycle.

That is very odd.. has someone timed how long it takes for the battery to get to 100% Just today I got the please charge now message.. it took 2 hours give or take to get to 100% it maybe you need to cycle the battery. I am using my blackberry 9700 battery charger ( OEM one was left in my hotel room ) The blackberry is output 5VDC and 700mA.
I've noticed that charging the phone using a USB port takes a lot more time that when using an AC/DC adaptor. The USB ports on my PC give out 100 milliamps while the AC/DC adaptor that came with the phone gives out 700 milliamps. Are you charging using a PC USB port or an AC/DC adaptor?

I've had this happen a few times I plug the phone in at night & when I wake up it's still charging and warm. I now shut my phone off before plugging in the charger & have not had the problem. My guess is some process is running in the background preventing it from properly charging.
ya just cycle the battery few times and it should be okay. it should be noted that the x10 will charge to 100% and stop charging until the battery drops down to 90% (at least for me)
Phone off worked!
Had a same weird issue after 5 months of usage. First 5 months were fine (needed to charge once every 24 hours). Have noticed in past 2-3 days that when I leave it for chanrging overnight, it does not go to 100%. Sometimes it would go upto 76%, other time 86 and so on. Cannot understand this. Have not installed anything in last 2-3 days either. Do not know the root cause but solution suggested by Phoneguy above worked. That is, I put netwrok setting OFF and then switch my phone OFF. Then I plugin phone to charger and start charging. This way it is getting charged to 100%. Hopefully this workaround will last for another year, at least

Mine does the same thing. I checked with battery graph. It charged to 100% and then it'd stop and drop to 90% and charged back to 100%, in repeated cycles. Is this just a X10 thing? I want to have 100% before leaving the house!

This is normal and for Security. When you leave the Phone charging when it has 100 it stops Charging until 90 or something then charge again becouse if it wouldnt do it your Battery will run too hot and could make real damage.

The phone actively discharges the battery when plugged in. I've tried the above suggestions and they worked, but only found small success as the battery wouldn't charge past 40%. Now my phone will not boot and the battery is completely drained.
I called SE North America last night and they told me that I broke the battery. I called BS and they then told me that they'll send me a free new battery as a courtesy despite it not being covered in the warranty. Overall, a pretty good experience, but the key point the rep said was to not trickle charge the battery.
I do have a sneaking suspision that it's not the battery because it's only 5 months old, but good because they didn't say anything about the phone not being officially released in the US and not being supported by a warranty.
I hope this post doesn't get deleted as well...lolz.
here it is my graph for the last day, plugged the charger aroung 4pm batt was at 13%, in the office and around 8pm from home, if you see, from 8:44pm to 9:41pm the batt was at 100% an then it goes down and reach 60% at 3am, so it was discharging, and then it tried to charge to reach 100% but couldnt. at 6:30am i woke up and bat was at 78%. so, how can i get it to keep the charge, i dont mind going form 90 to 100 but not going from 100 to 60 and to 100.
anybody can help?

[Q] About battery life and charging

So I had my GS2 fully charged last night. At about 415am I played Game Dev Story for about 30mins and went to bed. I wake up this morning at around 1030 and find my phone completely dead. Obviously this freaks me out since I just got my phone and it should not be going from 100% -> 0% in 5 hours of being idle. Now maybe I didn't turn Game Dev off properly and it was running in the background? I don't know. I got this phone last Monday and this is the fastest it has died. (Even setting this one aside, I'm extremely disappointed in the battery life). Also, I plug it in to charge after I found it dead this morning and went back to sleep. Wake up 2 hours later at 12pm and see its only charged to about 40% and the phone is really hot.
Are these normal for the GS2? It didnt get hot during previous charges (atleast I didn't notice it getting hot). Also what is the average battery life for the S2 and how long does it usually take to charge from 0-100? For some reason I feel like there is something wrong with mine and I should be exchanging it but unfortunately I did root it so undoing the whole process will take some time since I'm still waiting for the jigg.
Normal charge time from zero to full 3-4 Hours via stock charger .
Excessive battery drain multiple posts on the problem .

I don't think anything is wrong with the battery. You can see the battery usage graph, and post if needed. And the device takes around 3 hrs 15 mins from 0 to 100% charge with AC charger.

Is there something wrong with my battery?

Hi Guys,
I bought this new Galaxy S3 handset from Vodafone charged it for full first time no problem just for the second time charge I left it in charge for till morning which I started charging midnight so till 8 am it charged than I unplugged it and used it fine.
Today is the third time charge now the phone charged 100% I unplugged it straight after seen fully charged on idle after 52 min and just one phone call to vodafone support on the phone for about 5 min the battery dropped to 95%.
Is this normal?
or do I have this free battery drain membership as well?
Thanks,
Your phone, to protect itself, charges to 100%, and then takes itself off the charger and discharges to ~95%. When hit hits the lower threshold it will put itself back on the charger until 100%. However, when it hits 100% the first time, it considers itself 100% even if it may actually be at about 95%.

My battery charging routhine ok?

Is my charging routine bad? Here is my daily recharging
I let it charge over night. By the time I get home its normally in the 60% or so. So its left on all night until about 7am.
Then about half way through my day I charge it again while I'm at on my office. By then the phone is around 70%. So I let it charge to 100% then move on with my day.
So about 2 times a day I charge my phone. Is this healthy for the battery or does it not matter? I'm trying to get the most out of my battery. I seem to burn about 3-4% per hour with it just sitting on desk. Thanks for any advice!
Well my battery die sooner charging it as often by chance?
thats about how i do it and have never had a problem
That's how I do it. I wait till it's dead or close then charge. It's probably better to do it like that than every night because if your like me it gets to about 30% at night.

No at the end of the night when I get home its around 60% or so most nights. I then let it charge to full over night. I then unplug it in the morning and charge it again at my desk around noon when its about 70%. There for it never really gets any lower than 50%. I must be honest I dont fully understand the best practices of battery charging. I care only because I can not just buy a new battery like I could if my S3 died. So I am making sure the way I charge my battery is not killing it.
letting it die and charging to 100% are worse than charging from say 10% to 95%. read this to get info on battery life and charging

Battery discharged instead of being charged

Hi guys. Let's see who can help me with this puzzle:
Every night before going to bed, I turn off my phone and plug it in to its oem charger so that when I wake up I can start with a full battery.
But this morning I found that not only did my phone did not charge overnight, but instead it was COMPLETELY discharged.
I understand that maybe I didn't plugged it all the way in or whatever and so it didn't charge, but why was my battery completely dead? My phone was off and nowhere near being discharged just a few hours before. Why did that happened?
