Charging time

I find this tablets charging time so annoying I'm coming from a zoom with charged so fast compared to my note

Not trying to sound mean, but what's the point to the thread? Is it a question asking how to improve charging times?
BTW, I have a Xoom and I think it's just that it charges a lot faster due to the special charging port.

It will charge much faster if you connect it to 220 volt power sources, rather than 110.

Well I wanted to point out that it is an annoying factor for people to think about when considering buying the tablet but I understand your point

Ummm... wall voltage won't affect it. The device only takes in 5v regardless of the where you plug the charger.

Is it just me or do you guys think its slow charging

up to 90% it seems pretty decent. it's that last 10 that seems to take forever. I think the last time I charged it I went from 30 to 90 in 2hrs then the last 10 took another hour.

I ran my note into the ground today and then started a stop watch to see how long it would take to fully charge it. 4.5 hours!!!!
Mine takes way too long to charge also!!

Charging a battery faster leads to more heat which reduces the life of the battery. A very high capacity battery will take longer to charge, all else being equal.
They could have sped up charging by using a non-standard supply voltage/current from the charging cable (like ASUS Transformers, which uses 15v instead of 5v) and thus charging the battery faster. But it would have just got a bit hotter which is not good for the battery.
The battery stores many times more energy than a smartphone battery, yet it only takes about twice as long to charge. I think that's pretty decent.

Given the battery's capacity (7000+mah) and the charge rate (around 2A) I'd say the charge time is right around what I'd expect.

I found the charge a bit slow aswell, but the battery last so long that it balances things out for me, i was disapointed at first until i realised how well the battery performs, regardless what apps i used.

Yeah, Im not too worried about the 4.5hour charging time, my battery lasts me a few days and I can always plug it in before bed and wake up to a fully charged tablet.

I use my tablet during the day and before I go to bed I put it on charge and it's full in the morning. Do some people use their tablet so much in the morning it's out of juice by the afternoon? Give your fingers a rest. My battery lasts me usually all day. Even with looking at YouTube etc.

Slow charging after last firmware update
When I went to bed last night I had 19% power left. Like I normally do, connected my Note to charge overnight. Woke up 7 hours later to find that it had only charged up to 49%. Within 5 hours from a depleted battery, I usually have a full charge. Any thoughts as to why this is the case?

My galaxy note 2 charges faster than my note 10.1. But I have no problem with it.

I just bought my note yesterday, and I have to admit I was so surprised when I charged my note. It took 4hr to go from 7% to 89%. My previous Asus transformer tf300 can go from 0% to full charged in 2 hrs.( Not really big deal but it will be better if Samsung includes high voltage wall charger .

It sounds like you may have charged with your note 10.1 turned off.
The note 10.1 like many other tablets needs the tablet to be on while charging so the tablet can regular the rate of charge.
My Note 10.1 charges much faster turned on with WiFi, Sync and GPS disabled.
Mine goes from 25% to 100% in about 3.5 hrs.
from 90% to 100% takes about 45 minutes.

So do I (hello, fellow convert! ) and the real reason the Xoom charges faster isn't the port, it's 'cause the charger is 18W and is of a higher voltage (12v/1.5A vs. our 5v/2.1A). (I guess it could be argued that they had to go to a different port to not violate the PDMI spec the Samsung units use, though.)

You're being funny, I hope - our charger (just like any other charger released in the last decade) is a Universal Charger (100-240V/50-60Hz) so in any case the output voltage and current is the same no matter where in the world you plug it in.

That's not really true, though, as our tablet is in fact on when you're charging it- if you tap the power button when it's charging in the "off" state, you'll see that battery animation, and that's in fact a fully-running kernel but instead of running "Android" it's a special run mode more like a Recovery. The kernel is in fact running and alive.
FWIW my tablet charges far faster when off vs on, as there's far less simultaneous drain on the battery. Not sure what's going on with yours.

Back to normal

I hadn't completely shutdown my tablet since the update last week. I did so yesterday and now charging times seem to be back to normal. Something new from the update I noticed, when batery gets somewhere around 20% left, the battery indicator changes from green to yellow.

My tablet gets about 10 hours on battery, or more if im just reading the web. The most intensive app I run is candy crush and s-note.
That being said it seems to charge quickly, in about 3 hours. My complaint is the short charging cable it shipped with.

Bad Note?

Received my #Note5 last wed. Brand new out the box. When i got it the battery was at 5%. No problem. I turned it off until i got home. Good home. Charged it. I noticed after an hour of "fast charging" the battery wad at 93%. I fell asleep, woke up 2 hours later. Battery was still at 93%. I unplug and decided to let it discharge so i can try again.
Second charge, the battery gets to 100%, but then quickly drains down to 92%. (No exaggeration, the battery went down to 92% in 5 minutes). This happens again on the 3rd charge. Abs since then i only get about 4 to 5 hours of battery life with regular use. (Nothing excessive) it even dies quick on standby and on power save mode. Did i hey a bad Note? I've read reviews about the battery being pretty good, but I'm just not seeing it. Wondering if i should take it back to sprint. I'd it worth it?

Exchange the device. Won't hurt to try.

Please take it to a Sprint service and Repair store and have them look at it. This does not sound like the correct behavior. Thanks!

I did. The guy said it's something internally wrong. So I'll be getting a new one. ?

I am glad that worked out!

Smh. Same problem. New note, had it about 3 weeks now, battery still giving me problems. Im not doing anything crazy or putting any strain on the battery and thus is whats happening. Is it just me or what? Seems like im the only one having an issue with the battery life. Smh

Try this before taking it back.
plug your phone to the charger and wait until it shows 100% then.. Dial *#0228# unplug your phone and hit quick start, you may see a popup warning , just hit OK, unlock your phone and you will realize your phone have been lying to you
Plug it again and repeat until level 100% matches with your battery icon showing 100%, you may not need it, or maybe need to do it 2 or 3 times
I have not had any issues on my note 5 but it worked great on my note 3.

Ok so update.. monday when i got home i decided i wasnt going to fast charge my battery, instead use the regular charger adapter. Betsy is at 100% tried the *#0228# said the battery was at 100%. Went through regular use and the battery ended up last about 12 hours. (Minus a few hours downtime for me being sleep ill give it a good 8 hours) ok cool. So after ut got down to about 20-15% i charged it again with the regular adapter. This time (with sleep time added) i got about 16 hours on the battery. Ok cool. Another regular charge, 16 hours but i charged it here and there in between. Today around 4 i decided yo fast charge it. 100% around 5 o'clock. Its now 3:16am my time and im at 29% 9 and half hours on the battery... i also noticed in the beginning on fast charge the battery died a lot faster. So i think what ill do is charge it with the regular adapter for now on unless I'm in a situation where i have no choice but to fast charge like if im at work or something. All is well now. ???

S2 charging time - why so slow?

Everybody knows first smartwatch problem is battery. Having to charge it daily is like a nightmare.
But there is anything still worst? Yes, if you have the S2 you know it: the ****ing slow charge!
I am still surprised, and cannot undertand, how can it be. Ig the battery capacity is less than 300mah, and the charger is 700mah/h, why it takes so long to get it charged?
I think Samsung had a big error in this issue.
My previous Pebble Time battery lasts for 5/6 days, and what was still better is that in 30 minutes you have battery full.
You can fail in one of the two factors (battery duration or time to charge), but not in both. And Samsung did it.

Mine takes ~ 2hrs to full charge.
Agree, too slow.

I shut down the watch for faster recharge, but haven't used a stopwatch so far. I have to reload every second night and i am fine with it

Mine charges pretty fast, less than a hour and it is full. But another thing you have to look at is this is wireless charging which charges slower than regular charging. No gold contact points or anything. FYI I have the 3g version, don't know if that makes a difference or not.

Mine takes around 2 hours too. It's true that QI normally is slower than cable, but it depends also in the power of the chargues. Normal QI chargers are 1000mah and they charge batteries 10x bigger en same time... and s2 charger is less than half the power!
So the problem is not the charger...

Sure you can apply a higher current to charge, but most battery with that size just cannot affort that high current and will die very soon, so many will limit the current. There exist small battery can recharge at high current, just not many using it.

Pebble Time battery size is only 150mah and charges via a wired connection. No one is failing anything.

Wireless charging has losses maybe around 30-50%. So that 700mA of input from the charger will only give around 350-490mA of output. Plus the fact that we charge it while the watch is powered on will also be another factor to slow down the charging.
Also, pebble doesn't give you plenty of options to do so lesser user interface means lesser battery drainage, not like with the s2, you can do plenty of stuff which will result in you always touching and using the watch.
As for me, i've personally tested the watch. At minimal usage (maybe just the same usage I do when I was using a pebble) i got 5 straight days without charging. And I fully charge it at 1.5 to 2hrs.
Ps. Sorry for bad english.

2hrs here. Make sure you use the supplied cable, I find if I use my s6 one with my Gear or Tab S it is slower ...

It may. The 3G version uses a Qualcomm SoC and it may support QuickCharge. I haven't timed my 3G but I'd guess it charges in an hour-ish. I also keep it off when charging.

Charging Question

Is there any issue with charging the S2 every night, even if when you put it on the charger it's only down around 60%? Will it hurt the battery any?

No, it won't hurt it. What hurts lithium polymer batteries are completely discharging them, and storing them at full charge for more than a week.

When I put my Gear S2 on charge at night it's usually at around 30%. The thing is, when I take it off charge in the morning, it's pretty warm / hot. Is this not a bad habit?

Confusing Fast Charging Issue

My S10e is like a week old now and I was charging using the fast charger and assumed everything is on track. When battery hits low like 10% and I put on charge, it says 1hr 30mins or so remaining until full but it's taking way more time that that. Today I noticed that my dad's S9 Plus charges way faster with the same S10e Fast Charges, I am confused and not able to understand why this is happening. If I am on 90% and I charge S10e it says 10-15 minutes to complete the charge and takes that much time approx, when I put S9 Plus on the same with 10%, says 3 minutes until full and finishes it in around 4mins. Why is this disparity?
Also, I did charge my S10e initially with the MacBook charges as I read it's safe but my phone never charged on time and heated the phone so I switched to Original charger. What can be done to fix my issue.
Thanks.

Not sure if it's any consolation, but same sort of scenario with my note 9 compared to the s10.
Edit. I use slow wired charging for both.

I had my phone wirelessly fast charging overnight (I know...), the phone was at 100% in the morning when my alarm went off, but once I took the phone off the wireless charger the phone powered off and was at 0% battery. Has happened twice. I now have wireless fast charging disabled.
