My Fuze doesn't charge when connected to charger or connected to sync cable, I notice that when i connect to the charger and leave for a while the battery percentage remains the same, if i reset the phone the battery level will show a higher percentage, number would decrease but never would it increase when charger is plugged, to see the increased figure i have to reset the phone. For example, if my battery power is 1% and i plug the charger to the phone, it will remain at 1% the battery icon wont even come on, nor does the LED indicator, If i reset the phone then i would see say 20%, if i reset right away then it would show eaither a higher figer like 37% or a lower figure like 11%. I really dont whats wrong.
If we leave the battery display.
Could you confirm whether your battery is getting charged or not. I mean charger or connector is working.
How old is your battery? Could it have been over discharged?

Yes the battery is getting charge, it just doesn't show the percentage increase nor does it show the fork like icon when the charger is connected, and its doesnt sync. However The battery does get charge.

I have two batteries, one that i normally use, which is abt a year old. the other that i charge as a spare and carry with me every once in a while is abt 6 months old, and the i have tried them both,i get the same results.

Hey I was just wondering if its bad for the calibration of the battery to leave the tablet docked in the keyboard all the time?
I dont use the tablet while its charging, i usually always charge it to 100% (while docked), and let the battery drain out completely (while docked) before charging it back up again.
Just don't want to mess up how the battery calibrates or anything (so in the future whenever i use the tablet by itself it won't drain out quickly due to bad calibration)
As long as you charge it to 100% and then disconnect the AC adapter, you won't have problems.
Since the TF has two batteries (one on the tablet and one on the dock), it will manage them both to drain one first and then the other.
The thing that messes up battery life is if you continuosly charge it despite not being drained. Also it isn't wise to let the TF die on battery and then recharge. Recharging the tablet when it asks for it (19-15% of battery remaining) is a good practice.
Cool thanks for the tips, this is my first Tablet (but my fourth android device), and was wondering because i noticed the dock drains out first and then the tab starts draining, but as the tablet is draining, it slowly trickle charges the dock at the same time (so it can still be used).
ex.
TF = 100%
Dock = 100%
then
TF = 98-0%
Dock = 0-3% (once the dock hits 0%, it starts charging off the TF but just enough to use it until the tablet dies)
PS. I created a sugar sync account from your referral so you could get more space lol
Sorry to revive an old thread... but for clarification, should you let both the dock AND the tablet drain before recharging, or is it ok just to recharge as soon as the dock runs out? this way the dock battery doesn't sit at 3% until the tablet battery dies (sometimes a 2-3 days)...
also, how long is too long to leave the tablet/dock plugged in after its been charged? (e.g. if you plug it in before you go to sleep it will be fully charged at least a couple of hours before you unplug it... is this frying the battery?)
thanks and much appreciated!
I dont think that leaving it plugged in is frying the battery, because it stops charging when its full. Also dual battery widget info shows when the battery was charged last time. e.g. last night around 4am plugged in tablet with dock to charge, woke up at 9am, both batteries were 100% (and not hot as while charging) and battery widget showed exact time when it stopped charging, which was around 7am. Rest of the time while plugged in it does nothing i guess

Thanks for sharing your experiences and the logic... That makes sense to me too... However, I do notice sometimes that the charger is quite hot still in the morning.... which makes me wonder. Add to this the whole idea of product life-cycle and planned obsolescence (and things such as internal non-user changeable battery) and I get a bit sceptical... but thats probably just me...
Modern batteries don't like to be drained and last longer if they're 'topped up' on a regular basis. The only time a battery should be drained now-days is if your calibration is off and the software needs to see where the 'top' and 'bottom' of the charge range is.
Also, if your charger continues to charge your battery once it's at 100% you should have that replaced as it's broken.
The old habit of 'deep cycling' your battery is for older style batteries.
If I'm not using my tablet it's on the dock, on a charge. It's fine.
Is there a way to monitor the dock battery?

try 'dual battery widget' available in market... (if this is what you are talking about...)
Or check out the themes/apps section for the official widget from the prime. There's one themed to look like our tf101. That's what I use.

Hi
I have Samsung Galaxy S Plus and I'm looking for the following information:
1. Does the phone drain power from batter when it is charging it?
2. Does the phone drain power from the batter AFTER it's 100% charged, and is still connected to the charger/USB?
cheers

1. yes, you can drain your battery while it is charging if the charger is weak and your phone is under heavy usage
2. yes, because to improve battery life, the charger will let the battery go from 100 to 9X something, then begin charging again. (Same for laptops)
Hi Dark3n and thanks for your response.

?? Are you positive about this?
I mean, improving the battery life is charging it to 100%, and then not draining power from it, if it has an option to drain power from outside source.
ps. I have Dell Inspiron 6400, and it does not drain power from battery when fully charged and still connected to the AC outlet.
cheers

A good charger will offer something about 500mA+ of current, a weak one less.
If the current of the charger is not higher than what the phone currently drains, the battery will not becharged.

I'm not 100% sure, but fairly sure.
Also improving battery life would be to never charge till 100%.

I see. But if that was the case wouldn't Samsung doing the worst thing possible to the battery inside it's own phones?
Try to follow the logic(if the phone was constantly draining the power from the battery):
The phone is charging. It reaches 100% (so according to your article it's not good), then once it reaches, it can't go beyond that, but since the phone is taking power from the battery, the batter instantly goes below 100%, but then the charger tries to charge it back to 100%. So it's not only charging it to 100%, but it's doing it CONSTANTLY as long as the charger is connected to the phone.
If either of those information was true, Samsung would just conciously damage it's own product.
...
I contacted the Samsung Live Chat just now, and samsung employee told me this:
"P.: The phone takes power from the charger/USB when charging."
"P.: Yes, I am sure. All the phones takes power from charger/USB while charging."
"P.: Yes, you are right. The phone does not drain power if it is still connected to charger."
Any answer to that guys?
Hi everyone
My problem is.. my DS started to charge slowly.
Now it doesn't really charge slowly, If I check the voltage, I will get like 4220mv but as soon as it reaches that, the charging graph just goes flat.
If say I have charged it to 70% and it started going slow. i switch it off, place on the charger, and the lamp goes green. I turn it on, and it is showing 100%.
I have tried calibrations, diffirent kernels, wiping, factory resets e.t.c.
Another thing is that if I will run a v6 battery calibrator,it will show that actually I should have a 100% charge although a phone is showing only 70%.
So the summary: Phone charges normally when off (when recovery monitors charging), showing the correct voltage when on... But showing the wrong percentage if on charge.
Also sometimes if the battery is like 14% left. And I turn the phone off and then on again, it will show 22% bearing the same voltage as when it was 14%.
Question: Is there any way to tweak the battery indicator so it would show % values same as the v6 calibrator does it or is it a hardware fault, if yes, which part of it ?
This happens to me on my older (original) battery, but not my new one. I bought the second battery when this problem started happening. So, I think it's just a symptom of an old battery.
By the way, if you leave it on charge long enough, it will eventually jump up to 100%.
Other than this weird behaviour, it has no real impact on anything.
Sent from my Nexus 7
Thought so, mines been acting similarly lately, but strangely enough it seems to be getting better
I think I found out..
I actually purchased a new battery recently, because my old one was jumping like crazy and started discharging in a few hours..
This new battery I bought from a mobile repair shop.
It is a cheap chinese battery with no name, anyhow I just took it out to take a look at it...
And guess what, it sais 1200mah..
Can the phone be confused because of that ?
I'm running the 12/28 CM10 nightly, and I'm having an issue with charging my battery. When the phone is on, the battery charges normally to 90%, at which point the LED changes from red to green, indicating full charge. If I leave it plugged in, the phone continues to charge to 100. However, the battery doesn't really charge past 90 because once I begin to use it the charge drops really quickly down to 90. Similarly, if I restart the phone, even if it said 100 before, when it is on again it says 90. I have had this issue with previous CM10 nightlies as well. It is a software issue, because if I turn the phone off and charge it, it charges to 100.
Any ideas on how to fix this? Thanks!
This is a suggestion out of the blue but maybe try recalrubratung your battery

This is the intended bahavior. The type of battery used in phones last longest when they say between 80% and 20% of charged. So your phone will pull the maximum amount of power it can until it hits 90% then reduce power draw to a trickle charge.
The rapid drop is power is often the chip in the battery lying that it is fully charged when it is not. That is why you may see a rapid decline to 90% where your battery drain will go back to normal.
You might also see the phone telling you that it has 15% power then turning off. Upon reboot it will say it's at 0% or 1% that also is the battery trying to protect it self from damage.
This is a simplified explanation of how all phones work these days. The only difference you'll notice is how good the software is designed to lie to you about the power level. If it's good you won't notice these types of anomalies but they are still there.
Have you wiped battery stats?

Thanks for that informative answer. So I take it that means there would be no performance difference between turning my phone off, charging it, and then using it (with it saying 100%) vs leaving it on, charging it to 90% (green LED turns on) and then using it?
I changed the battery buying a new one on amazon, the problem was that when the phone was at low % it shut off sometimes at 20% sometimes at 40%. Ater changing battery i noticed that the problem disappeared for a week, but then reappeared, so i changed the charger and tested different cables but both charging and discharging are irregular, it charges to 100 in 10 minutes. So i ordered a new charging board on amazon, i changed it but the problem persists. Im desperate, i dont know what to do, sorry for my english. I thank anyone in advance who wants to help me.:crying:
could always try recalibrate your battery

I think you should change your phone's battery mate. I changed mine last week and it's as good as new now. Charges and discharges exactly how it's supposed to. My battery had similar issues before I changed it.
TRY CALIBRATION ?
1.Discharge your phone fully until it turns itself off.
2.Turn it on and let it turn off again.
3.Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4.Unplug your charger.
5.Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on the screen as well.
6.Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
7.You want to repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without it being plugged in.
8.Now, install the Battery Calibration app, and before you launch it, make sure your battery is at 100 percent again, then restart.

He said he just put in anofher battery he bought on Amazon. I'm wondering at what point you stop buying parts for what is becoming an unsupported phone and just get another phone.
