[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?

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??

Nexus 7 2013 not fully charging

I have had my N7 for a few days now (fully rooted using Buttered AOKP ROM and ElementalX 1.8 kernel). I have a US power adaptor with a UK adaptor. I have my N7 charging all night but it doesnt seem to go all the way to 100% - it gets to about 96%. Is this a known issue? Is it worth returning/exchanging the unit?
I bought it (£170!) new from play.com.

It's not a feature to extend the battery life of the device as in how many hours you can use it off the grid. It is a feature to extend the battery life as in how many charge cycles is the battery gonna last. It has been shown that if you drain a battery fully and recharge it to 100%, you put more strain on it than if you let it drain to 20% and charge it to 80%, that way you increase the usable charge cycles by a lot. That's what that feature is supposed to do.

My n7 has not been charging fully either. I am using the stock charger and I'm running PAC ROM for about 2 months but this just started happening. Idk why. This picture is after I had my tablet plugged in all night while charging

[Q] N900T Extremely Slow to Charge- Tips?

Hello,
I bought a gently used N900T a few days ago. The device is awesome and works perfectly, except for one thing. Charging the phone with the Samsung charging cable+ac adapter takes longer than forever. It charges at a rate of approximately 8-9% per hour.
A few notes:
Device on, device off, it doesn't matter. It charges at the same slow rate.
The battery itself, once it charges, holds that charge very well.
The slow charging happened both when I was on the stock rom and on my current Slim Rom.
I have ordered a new charger and a new battery. If the slow charging persists with these new accessories, am I doomed? Is the slow charging a known issue for the Note 3? Besides the new equipment, does anyone have any advice on how to solve this?
Thanks so much!

I am using a genuine Samsung Note 3 charger. The replacement coming is another genuine Samsung Note 3 charger. I'm sincerely hoping the one I have now has a cable problem or something. I really, really like the phone but I'm wondering if anyone else has seen a similar story or knows of a possible solution in the case that the new charger+battery do not work.

Well I have to be honest from dead it takes about 2.5hrs to get back to 100. On stock.using the wall charger with 2amps. When he gets his new charger he should be good or a good kernel swap. Either way it should come back to normal

I got a new charger and it's still charging at the same slow pace. What could possibly be wrong with my phone? The battery holds a charge, the phone works near flawlessly. I'm dumbfounded.

You gonna have to do testing or replace phone. Me I would change kernel just cause it takes 2 seconds. Let it ride a day if no change then a factory refresh. You have checked that no app is killing phone as fast as it charges right?
TWEAKED N3
Edit. I was just on his thread and a few guys having issues with either bad batter. UV/ oc .try a different ROM and kernel. Fresh install meaning Odin back to stock and start all over. Sorry good luck

As weird as this sounds, I tried the charger in a different outlet in my home and it works a lot better. The battery charges quite fast from any level to about 96%, then starts crawling again to 97, 98 and stops at 98. I opened battery calibration, which shows the battery at 96% and 4337mv, which is the same mv level as 100% normally if memory serves me correctly. So I'm thinking the battery is "full", but for some reason won't go to 100% without a fight. Perhaps if I clear my cache+dalvik cache? Any other suggestions?

What was wrong with mine it was the charger. The usb wasn't connected all the way in the AC therefore was only charging like it would through computer as soon as I fixed it with a blow of air and a gentle push it right away started charging AC phone charged in 2 hours

I could be wrong but I noticed my charging is slower when I stick my charger into a surge protector power bar as opposed to a standard wall outlet.

Mine was the charging cable I used a regular USB charger cable and it charge fast

It's bad as it seems. The average is 3-4 SOT wich is really bad..

Any comment from anyone with the unit on hand?

Thats what I'm waiting on right now before pre-ordering this phone.
The things that you have to consider is
1) Is GPS enabled?
2) Screen set to auto brightness or always on 100%?
3) On LTE mostly or WiFi?

So far the battery has been fine for me. It seems likely that for the average user charging once a day should be enough.
Anything specific you would like to see tried?

When charging while doing nothing it takes 2 hours to charge the phone. When charging the phone and using it like browsing it takes 4 to 6 hours to charge to full
Is this normal or do i have a faulty device?
On my Note 4 and Galaxy s6 and Nexus 6 it takes 20 minutes max extra to charge to full while using the phone

[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.
