um.. turn off your phone, and plug it in to the charger
wait for a green light. un plug, wait 10 sec. (phone is still off) plug back in until the light turns green again, should take like 10 min. then thats a full charge u can get.

All Android versions have a regulator that only charges up to 97 then gradually let's it discharge to about85 then it will charge it back up again until you take it off charger. That feature is there in order to prevent overcharging. The only way you can truly get 100% is if you charge your phone while the phone is turned off.

[Q] Li-poly Batteries Questions

Hey everyone,
I received my Xperia Arc S 3 days ago. Well, since it's my first smartphone and I was not used to it I first used all the battery and then I gave it 12hours of charging.
Well it seems I did it wrong since Li-Poly batteries shouldn't be charged on that way. So, here are my questions.
1. The fact of letting my phone completely discharge and then give it 12 hours charge was a BIG MISTAKE?
2. How can I correctly charge my device?
Thank you all.

Why it should be a big mistake?
I've done the same:
buying
completely discharged
charged for many hours
I haven't any battery drain or something and I also heard you should do that (correct me if I'm wrong).

Hey pal,
Well I thought it would be the right procedure as well but it seems that with Li-Poly batteries we shouldn't let them completely discharge as it may affect its life. However, I am not sure and I still don't know if it's the truth! Let's wait for some more feedback and see what's coming.
Plus, how long does your battery stand?
Note: In addition, thank you for your response

These new batteries need no charging circles etc
You're good to go

Excuse me Flo95,
Did you mean charging cicles? What do you mean by good to go? That I don't have to let it discharge and I may charge it whenever I want?

If I'm correct previous batteries had 5% circles and current batteries have about 20% (as a full charge).
He means that everything is okay and you won't have any problems.

Ok buddy,
Thank you for that!
Well, plus, can I remove the device after 3 / 4 hours (as long as it says 100%) of charging and normally use it with only that time of charging? What about the opposite? Let it charge all night long while I sleep? No problem with both methods?

No problem with both.
Usually I'm charging over night too.
But if I remember right a complete charge only needs about 2 hours.

Well, my one is charging for 2 hours now and it says its battery is 88% charged!
I have to leave in 1:30 hours and I guess It'll be fully charged then. Hopefully I won't have to charge it again during the night

You can plug it in as long as you want, nothing will happen exept the battery gets charged.
Sometimes I plug it in 5 mins before going out and my battery is ok.

[Q] Battery Taking Too Long to Charge

I've had my N2 for a few weeks now. Suddenly, it has taken much, much longer to charge the phone. I calibrated the battery, drained it to 0 and plugged it in. 3 hours later it's still at 50% (and the phone is charging while off. Any suggestions?

Are you using the stock wall charger and cable that came in the box?

The reason the battery is taking so long to charge is because you ran it down to 0. If you want your batter to last longer it's best to use the 80 / 20. What I'm saying is use the phone down to 20% and recharge back to 100%.

May be a faulty battery. Contact Samsung (I'm assuming that by n2 you mean note 2) and they'll probably send you a new battery.

I only had one issue, yesterday, and it was that my phone showed 25 percent charge on stock white Samsung charger/cable and I knew it had been on the charger longer than that. I rebooted and it showed 74%. Not sure what the hell this was about.

Old rules by what standard? Anytime using lithium type of battry is best not to run it down to 0%. I guess you don't have much experence with them besides your phone. I use them everday for my hobby. Sure you can run them down to 0% if you like replacing them quicker.

Huh? Its a lithium battery...those old rules dont apply. A little quick google on lithium batteries will explain this.
More than likely slow charges are due to a slow charge plug/cable...many prior posts on the charger.

Old rules were for NiCad tyoe batteries, where you did want to run them down to 100% and had to deal with other issues. If you do end up doing that Google search you will find the advice given is pretty accurate. Staying out of the high and low ends for long periods will give you many more cycles.

Buddy i am having the same problem ... did you find any sloutions
i went to service centre those assh**** have no idea and said that note 2 is a bigger phone so it will take 6 hrs to fully charge.
pl help me out

I know this would be obvious, but I figured I will ask anyway. Are you still running the stock kernel, or are you possibly running one without the capability to accept the 2.1A charging?

How can I check this??
Full charge of my Note 2 is at least 10 hours, it's to much
I have 4.1.1 original firmware

I have a telus note 2, I am running stock software, rooted, I drain battery down to 10% and takes abour 2.5-3 hours to fully charge with stock cable and charger. I have noiced on a custom room it always taking longer to charge. I always charge with phone off.in doing this , I usually can get longer life out of the battery as well.

You would know if you were running a different kernel. You would have had to install it yourself. If you are All stock (ROM, AC adapter, cable) then you have something defective.
Here is my screenon time with everything running all the time on cleanROM with 6400 mah battery.
-- Note II, TapaTalk II--

Batteries will last thousands of cycles charging to 100% from 50, but maybe 300 cycles charging from 0 to 100. Don't run your battery down so much. Charge it when you're not using it.

Note2 battery drain problem
I too facing battery drain problem in my samsung galaxy note2 from last 1 week after installing lattest software update.
Previously my note2 was charged quickly in within 2 hours. After software upgrade, which came as push message, my battery takes almost 5-6 hours to charge from wall plugin source.
Can any body help me in restoring previous version of software??

[COMPARISON] Dash Charge, Qualcomm QuickCharge, Normal Charge

Good morning guys...
I am really impressed with the new pattern that OnePlus has introduced with the OP3, the DashCharger and its improvements over other patterns, as speed and better heat dissipation.
I do not have my OP3 yet, I live in Brazil and things are a little bit harsh here.. but I bought (imported) one and I am just waiting it to arrive.
I saw in many reviews that DashCharge takes about 1 hour to fill the battery and what I want is: you that already have the OP3 on hands, could give us a feedback about other type of charging
and the time it takes? Can you use a normal 5V1A adapter and another one that implements QC2.0 and post here?
I want that because I have 2 units of QC2.0 charger and with the new OP3 I do not intent to get rid of them if the time to full charge isn't too different and buying the special cable/charger for me (and maybe other)
could not be easy/cheap and maybe it does not compensate!
If no one could do that test, I will perform it myself when I get my OP3... till there, if you could help me, I will appreciate!
Thanks for now and sorry about english!

I have the original charger, but i had a Nexus 6P too, and the 6P used QC 3.0. The OnePlus 3 is charging a bit faster than the 3.0. OnePlus charges 3% in ~3minutes, and the 6P was like that. I think you should charge your phone with the original charger, but in fact you could use QC2 charger i think. Hope i helped (Sorry for bad English)

Thanks for reply,
I would like to know how many time does de OnePlus take to charge from 0 to 100% with Original DashCharger, a QC2.0 and a normal charger... if you could tell in minutes (average)

I have the HTC 10 and the OnePlus 3. The OnePlus 3 is drastically faster than the HTC 10 with Q QC 3.0. I remember walking away frm my OP3 for like 10 minutes, it had charged about 20%. In abut 30 minutes it's at 63% and my HTC 10 is at 44%. My OP3 fullyharges in about 72-74 minutes, my HTC 10 is aound 1 hour, 40 minutes.

74 min?
i get a rate of 2% per minute charge.
50min for full battery

QC3.0/3.0 is also much more heavily affected by heat (and as such, using the device), whereas Dash charging is not since heat is dissipated at the charger itself instead of at the phone.
a bit harder to find dash charging accessories though..... at least right now

It doesn't matter, download an app called Ampere and check the intensity, it charges with ~4A for the first ~30 minutes and then lowers down to ~2A.
Conclusion: It charges super fast only first 30 minutes and then it slows down.

I'm very familiar with it. My point is dash/quick charging is purposed for when your phone is near 0 and you're in a hurry, it will get you as much as it can as quick as it can but with lithium ion batteries it's causes too much damage to go all the way to 100%

Well that, and naturally all batteries tend to slow as they charge, not to prevent damage but just the way they work. The reason it's "0-60 in 30 minutes" and not "0-100 in 50 minutes" is that after 60, all modern phone batteries tend to cap off.

I had a 6p before I bought the op3 and I totally disagree. The 6p took 45mins to 1hour longer to charge, of course the battery was a little bigger but it was much slower for sure.

yeah , calculate accurate and post it :good:

Mine went from 6% to 62% in 59 minutes today. It reached 100% after about 100 mins. Stock charger and stock cable. You have to look for the double lightning bolt symbol in the battery icon to know that it's charging rapidly. The fast charging only works with the stock charger. I tried charging with my Nexus 6P charger which charges that phone quickly but didn't charge my Honor quickly.

The company has made a claim that it takes 1 hr 50 min to completely charge with their OEM Charger. So I am sure that the QC3 works fine since the battery capacity is also 4000mah. Other phones with 3000-3300mah charge within 1 hr 30mins coz they have substantially lesser capacity.

just sharing the stats from last night:
22:51 @ 5%
23:02 @ 13% (11mins; +8%)
23:42 @ 50% ( 51mins; + 45%) // (40mins; +37%)
it does look like we can get about 100% in 2 hours.
and sorry, didn't continue with measurements coz i was already zzZZZzzZZz... tiring day.

Next time if you experience slow charging you can try flipping the cable 180 degrees and try. Because that's what I've noted and even @venugopalu007 also experienced similar thing.

I use Ampere from the playstore to test the voltage on all my phones, so I can figure out what connections work best.

I am also noticing the same thing. This is weird.

Mine can definitely go full charge under 2 hours charging from about 10%, BUT only if I don't touch it at all. If I use the phone at all during charging it charges at a literal snail's pace even if I open low power app like an ebook reader. Screen is always set to around 35% brightness, and I'm using stock in the box huawei charger. Ampere gives it a reading of 1060mA then it goes down to 600ish mA and it does display the doublebolt in the battery icon . Is that normal? At times it can charge for 40minutes while I'm using a game app and it barely increased 1%(screen on) While my sister using a micro USB charger on her xiaomi redmi note 4, had no severe slow down on charging times even when playing intensive games while connected to the charger( Same battery size I believe).
