[Q] hot charger - Galaxy Note 10.1 Q&A, Help & Troubleshooting

Not sure it was like that before, but when charging the charger is getting very very hot: is it normal?

Mine gets hot a bit when the tablet is charging, I think it's normal.

[Q] One X's horrible charging??

Has anyone experienced problems with the way their One X charges? Mine charges blazing fast and well all the way from 1 to 90 in about an hour and sometimes an hour and half, but then from 91 to 100 it takes easily another hour... and not just that, if i use the phone to talk or play a game while its charging from 91 to 100, sometimes it'll stop charging or even discharge!! i always keep it cool cause i know overheating causes it to stop charging for a while and I always make sure the charger is connected correctly both to the outlet and to the phone, cause if its a little loose on the outlet it also causes it to charge slowly i know all of that... literally I check everything and its all fine... soo just me?? or known from then HOX?? ive calibrated lots of times and it happens with all roms even stock ones....
EDIT: added a screenshot so u see wt i mean, and yes i did unplug it twice but that has nothing to do with the problem, it has happened letting it charge straight from 1-100 too
ive never seen this problem, it could be the rom/kernel too

It's actually how all Li-Po/Li-Ion batteries charge. Some manufacturers (cough Apple) show the phone/tablet battery at 100% when it is actually only at 90%. It's part of the reason when you do a full cycle of a phone battery you should leave it plugged in for at least one hour after you hit "100%"

HTC probably is displaying the actual battery percentage. (So it is at 90%). You could test it if you wanted by seeing how much current the phone is pulling when it hits 100%.
For example, I own a new iPad (yeah boo hiss). It will show 100% on the display, but the charger will still be pulling full charging current for 90 minutes or so. Apple displays 100% when the iPad is anywhere above 90% or so. It's the same reason why some phones will seem to take forever to go from 100% to 99% after they are fully charged.

aah well if thats the case then i think its charging accurately, cause when i unplug it exactly as it hits 100% it takes a while till it drops to 99%.. like i said battery life is good its just that last 10% taking so long to charge that bothers me.. also if i unplug it when its anywhere lower than 90% it drains pretty quickly even without using it much.. like if it lasts 12-16 hours unplugging at 100%, itll last about 6-8 hours unplugging before it finishes charging

My Nexus 5 gets pretty hot while charging (charger too), is this normal?

So yeah I wanted to charge it yesterday and after about an hour the charger was really hot. The phone itself was hot too but not as much as the charger. Is this normal?
Thanks!

It's charging well, I think the first time it took less than an hour to charge but now it takes about 1hr and 20min. I also experienced some major battery drain by Google Services the second or third time I charged it. Today Google Play Services went from 52% down to 19%. I hope it goes to 0 from now on. Thank you.

Oke, enjoy your phone and flash away if you want to
I take it your charging the phone while its on, and googles services are to blame.
Try charge when the phone is off and see if it still gets hot,
It will get hot while something intensive is going on.
I plugged in the charger about 20-30 mins. ago and the phone went to 40% from 5%. The charger it's pretty warm now. The phone it's not as warm, just a bit. I'm interested to know if the process of charging in certain circumstances (like the charger being too hot) has any influence on some apps such as Services. Thank you guys for your replies.

[Q] OPO dying after 40% battery charge

Hey folks
Lately my OPO started to have some hiccups with battery. So the problem is that once my battery percentage goes below 40% my OPO turns off. When I try to turn on the phone it never boots up. Any idea why its happening and solution will be greatly appreciated.
Note: I tried to have full charge cycle (going from 100% to zero)but it never worked. I tried charging phone while its tuned off and turn it on once its fully charged but it didn't work either.
Thanks
Sorry to tell you but your battery is likely physically malfunctioning and no amount of battery draining will fix it. Odds are, your battery has started bulging a little already.
Do you typically leave your OPO plugged into the wall charger for extended periods of time, even after it has reached 100%?
I damaged both my previous Note 1 and even a laptop batteries this way. Both would just shut off after dropping to a number like 50% or 55%. Both batteries had a bulge.

When did this first happen? What were you doing? Skype call? Hangouts video chat? Playing an intensive game?
Point being, was it super hot when it first shut down?

So now it appears to be fine? It can go below 40%? I'm confused. Or are you saying that it happens intermittently?
Before I was in original CM 11S but after change my ROM it got back to normal and it goes below 40% by the way I know that its sounds so weird

[Q] About battery

So guys i just bought this phone few days ago, and the first charge was only untill 96% and then i unplugged it, because its take too long... is this can cause some problem to my battery? or is it still safe??

Did you use the original charger and cable? Of you don't use those you'll experience slow charging. Charging only to 96% won't have any bad effects on your battery.

so youre saying that my battery is still normal?
and btw yeah i use the original cable and charger, now i can charged to 100% after i let my phone die (0%) and then charge it uninterrupted overnight (like about 6hours)
thank you for the answer!

Yes the battery should be perfectly ok. Sometimes the calibration can be a bit off but you've charged to 100% now it's all good.
I don't think charging your phone to 96% or whatever will cause any damage to your battery and why would it?

hey i have another question, this thing have been in my head for a while now i just wanted to make it clear for me
for example i have 80% of battery then charged it untill 85% and then unplugged it and use it for a while until drop to lets say 80% again, and then charged it again to 85%
is that also safe to do?
i just did that when unlocking bootloader and installing twrp recovery, seems like my battery been draining pretty fast after that..
sorry if this noob question annoy you, i just want to make it clear

That's perfectly fine with a lithium battery. Small top-up changes are actually preferred. It isn't recommended you let the phone fully discharge very often, it also isn't recommended to keep it at peak voltage (100%) for very long (try not to charge overnight). A lithium battery is at its healthiest within the 40%-80% range. So yeah, top-up charges are perfectly fine. About every 30-40 charge cycles (roughly once a month is fine) you should do a calibration by discharging almost fully (from 100%), then charging back to 100%.

Battery life on latest 4.70 firmware f3111

How's your sot on this latest firmware guys and did you notice any improvements from 3.81 firm version? I'm on 3.81 and I'm disapointed about the battery life. It's too short...

I really don't know what you're saying. Sot means screen on time. On the 3.81 firmware I'm getting about 4h sot, just browsing, youtube mainly on wifi, a little bit of data traffic. 4h, no games with screen brightness at minimum is just pathetic... Bad deal with this phone...

He's probably saying that his phone takes too long to charge from 90% to 100%. With that said though, I have yet to update to the latest version.

Even without updating to the latest version, I sometimes experience that phenomenon. Heck, my phone sometimes blatantly stops charging for no reason at all and I would have to turn off the phone to be able to charge it.
No problems for me thus far, but the battery is extremly week. I wonder if undervolting the cpu would increse a little bit the life per charge cycle... Anyway, I regret buying this phone, but it's my fault entirely that I did...

Unfortunately, my problem escalated quickly. The phone isn't charging anymore and I've tried different cables and chargers. It seems like my xa has a hardware problem, thankfully though I haven't rooted and unlocked the bootloader of this thing. Gomna have to send it back for warranty.

I think it is because QNOVO ADAPTIVE charging
That adapts your charging behaviour
Like many of us leaves the phone to charging over full night that damages the battery
So sony added a featutre qnovo adaptive charging that adapts charging behaviour and if someone is one of those people who left there mobile to plug in full night
It will automatically decreases charging speed from 90 to 100 %
