Hi
Just put in a brand new battery and the phone will not go into turbo charge. Best I can do on any charger is about 500mAmps. Battery will barely hold it's own when the display is on. Let me go through the specifics:
Battery was acting erratic (random shutdowns, short life) and was replaced with a labeled Motorola branded battery. I believe it was charging in turbo mode before replacing, but it was so erratic I can't say for absolute certain. No drama on the installation, it went very smooth.
Battery capacity is now great. The random reboots stopped.
Charging is very slow, less than .5amps. It says that it is charging off a USB port. It does not give the turbo charge message.
Tried four different quick chargers (2.0 and 3.0) and a few different cables. Also tired it on a 2amp USB charger. At least two cables were brand new. All the same.
Cleaned out the USB port on the phone. Thorough cleaning a couple of times, not much junk out came out. Also tried some alcohol to clean the contacts. The connection feels tight and has positive lock. No help from that.
Factory reset. No help.
It has had a couple full charge/full discharge cycles. No difference in charge rate.
I have a USB detector that I can plug into the charger and run the charge cable out of it to the phone. It shows 5.2volts and about .4 or .5amps. Doesn't show the high voltage charge (about 8volts if I remember).
One thing that is funny is the charge rate as reported from Ampere. It first reports 1-1.5 amps initially and then goes back down to .5 amps. I suspect it is Ampere acting funny, not the phone. The USB detector does not show the initial high current. There might be a clue in there somewhere.
The phone is running stock Nougat and is not rooted. I am beginning to think it may be a software issue.
Any ideas?

It could be the battery. Buying batteries has seemed to be trial and error for this phone. Where did you buy the battery from?
I know that problem with batteries. It's like a 50/50 chance of getting a decent one. I seem to have found a pretty good one. It was off Amazon, but it was branded Motorola. It says so right on front, if that is worth anything. It charges (just very slowly) and has great life. The phone used to do random reboots on the old battery, that is cured. I am inclined to think it is not the battery. Is there some specific check that you know of that would rule it out?
Thanks for the idea.

Fit the old battery again, if it turbo charges then the problem is the new battery.
good idea.

That was a good idea. I gave it try but it was still in the awful slow charge mode. But that old battery was junk, no life and random reboots. Based on the condition of the battery, that may not have been a great test I will just button it up one last time and recharge it every night. On the plus side: Life on the new battery is as good as when the phone was new. That is a very nice phone and I would buy another new one if they were available.
Thanks for the idea

Ok, i've been measuring my Nexus One battery. What I have done is:
- Let the battery to dischard completely.
- Charge with a slow charger or computer USB, about 500mA (the stock one is 1A I think).
- Let the battery to dischard completely again.
- Charge battery again with slow charger.
The battery gains are impresive, nearly 2x.
Now, charge two more times with the stock charger, and your battery lose life again!
I know, I know, this is against phisics, but I'm thinking that there must be a problem with some internal component of N1 that recalibrates badly with powerfull inputs. It might be even a software fault.
These are my measurements. Please do your owns and put them here. Remember to repeat two times in order to get good measurements.
I've charged mine via USB (500mA) numerous times and battery life is no different to mains charging.
Yeah, how would charging the battery slower make it last longer? You want it to happen so your brain tells you its happening i suppose

The only way to prove this would be to do a scientific method test, meaning charge battery to full, then play a high-res video for a few hours until the phone turns off. Repeat a few times to get the average.
Then repeat 2-3 times with the other charger, and compare the average times.
To full chagne the battery, need more than 10 hours. Tried different ROMs, Batteries, changers, cables. the same result.
It looks like a hardware issue...... but....
when I used a DC power supplier(5.2V, limit to 1A) and plug in the cable, it appears the DC current is 0.5A, and after 10 second, fall down to 0.1A. at least, in the first 10secend the hardware worked all right...
Do you use the original OEM charger ?
Have you tried a different charger ?
How old is your Note ? Have you tested a different battery too ?

I was quite surprised when I switched to the Note from the Dell Steak. My old phone would charge much quicker. The Note takes about six hours to fully charge I'd say. As a result I plug it in pretty much whenever I can.
- - Sent from my phone using technological wizardry
Yeah, Mine can take around 5+ hours too if im charging it from <5%
Bear in mind that it is a bigger than normal battery, 2500mah.
But if it is like you say, Taking 10+hours to charge, Id get it looked at, Maybe send it off for repair or something.

Isn't it bad to constantly charge your phone even when it still has battery?
I heard it reduces the battery's life span.
I dont believe it is, I often charge mine even when its got plenty of juice left.
It may reduce life span, But the battery will live longer than the time you will own the phone so i guess it dont matter
No one can help. feel bad.
I saw sevral links saying same problem, but no solutions... poor us...

From what I've read, it's what you're supposed to do with the current generation of batteries. But then there's so much crap floating about about batteries it gets hard to figure out what is reliable info.
And this is with the original charger? If it's not an official charger, there's a big chance the phone will draw only what's usually allowed across USB. Which isn't much... In fact, with USB, the power draw of GPS/screen on/games can make your phone discharge even with the charger on. So try the official charger, on AC power.
Same problem...
I have the same problem.
At the beginning, about 3 months ago, my SGN works fine, battery are charged to 100% in 2 hours maximum.
I'm buy the phone from a Samsung Store, all accessories are originals. Today I send my phone to the technical assistance and there's no problem with battery or the charger.
My problem stars about 3 weeks, with an alert about different voltages after a full charge, the problem was solved only removing the battery and waiting an hour. At the technical assistance, the answer was to charge the phone when it's shutdown.
I already try that, format the cache, rebuild the system, everything using the ICS LQ3 from Baltic.

Is the problme solved after remove the battery for 1 hour?
paddyzou, the problem with the wrongs voltages, yes, my steps to solve this:
- Full discharge
- Shutdown of the phone
- Remove the battery for 1 hour
- Full charge with the phone hang out
The problem with the low charge I think that was okay, it's seen to be happen in random times, I just flash another LQ3(France) version of ICS yesterday and seems to be working fine.

appreciate you so much. Hope it works.
Mine takes around 2 hrs to fully charge the battery. I use supplied samsung charger.

This is correct, a chemical reaction takes place while the battery is discharging and is reversed when charging(changing). The chemistry of the battery changes how they hold energy. The Lithium ion batteries in our phones can be charged any time, they have no "memory" characteristics like previous rechargeable batteries (NiCd).
OP, it sounds like your charger is going. My stock HTC charger (2-3 years old) now only charges at about 40% the speed, which means the phone will discharge while its plugged in. I recommend grabbing one of those tiny square usb chargers (1A 5v, not 0.5A). I got one for like $6, as long as its 1A it will be quick.
At first when I got my nexus 10, it was charging quite nice, overnight would charge from 30% to 100%, but recently it stopped doing so, for example tonight after 8 hours it got from 35% to 70%, all stock: same cable, same charger.
Also, sometimes I used to put it on charge while using it, like when watching video, and it used to charge even if slow, now when doing this it says charging but the battery level goes down....
can the stock charger or cable be damaged? why did it stop charging fast overtime?
I used the its usb cable and charger few times to charge my new OnePlus, which requires a high ampere charge, can this cause the charger to overwork and then damaging its power output?
I read about the pogo charger does the job better, but I also read about the 28/24 usb cables, and I guess that the stock cable is 28/28, they did it like this to sell pogo charger cables. but the main issue here is that with the same combination it was better a month ago....
I have multiple chargers around the house with various amperages that I use for all devices, except I do have a bit of fear using my oneplus chargers with others for your same reason
About a month ago we decided it was worth it to buy the pogo dock on eBay for our nexus ten so it can be used as a digital picture frame when not in use, great decision, it seems to charge faster than any of the other chargers and get to see pics of our newborn all day as well
Consider either this or buying a new cable/charger for much less money. Either way my best guess is this is what you need, but you can always try a factory reset or reflash stock to see if it is a software issue

Mine had the exact same problem after about 15 months use. Combine the slow charging with the atrocious battery life and you're left with a barely usable tablet. I later bought the pogo cable and switched chargers to no avail. Then I just said screw this and sold it.
My nexus is 3 months old, so it can't suffer from battery wear down in such little time.
Will try resetting the whole thing and try again....
Hello,
I am using One Plus 2 for a few years already. Lately I started suffering because of battery drain and long time charging. Problem is quite serious because while charging and using phone battery % is getting down. It takes whole night to charge it to 100% and in the midday I have 20% left.
I tried to use different chargers and cables. Didn't help.
Today I changed battery to new one. Didn't help.
Wiped out unofficial rom, installed official stock one. No addtional apps installed. Didn't help.
I am charging it with charge monitor app and while on AC charging I get very unstable charging graph. I need to turn off screen and leave phone untouched to charge it.
https: //zapodaj.net/21c02b80b986a.png.html
Where else to look for a reason?
Usually LTE connection drain the battery. Try disable it and try for few hours.
I tried to charge it with airplane mode. Didn't help neither.
Hi
Did you resolve your issue? I have same situation but I think that happened after when I do update Oxygen, now charger my battery is really slow and drain battery really quick. I can just leave, not touched my OP2 for all day and the battery after 8hrs got 30%. I buy original battery and still nothing change for better.

Hi
Have you tried to change the charging cable. I had the same issue and changed the charging cable. It worked for me.

Another problem is with a cable because original cables for OP2 can't buy anywhere right now, the company OnePlus has stopped production this cable for this device so I buy original cable Dash Charger from site oneplus.net
Three possibilities (at least):
* The charger is not working
* The cable is not working
* The battery is failing
Solutions for the first two are more obvious than the last one. Pick up a new or working used charger/cable. But the battery is a little dicier. And frankly, it is also more likely the cause for this than a bad cable or charger (esp. charger). But re the battery... No direct sales from Oneplus are available except via an official Oneplus repair job, which requires you sending your phone to them and them replacing the battery. Obnoxious, eh?!
The unofficial route? This is frowned on by many here, but not me. Buy a cheap ebay battery for the oneplus 2. Look for one that at least promises the battery's power matches the phone's specs. I bought one for $12 from an American seller (because I wanted a bit more accountability if it didn't work). They do work. They also take a while to start reporting their voltages and charges correctly, and must be charged / discharged completely a few times before things start getting accurate.
That's no official answer... just one guy's experience. Hope it helps.
Hi,
I own a Galaxy Not 10.1 2014 Wifi (SM-P600) currently running RessurectionRemix (https://forum.xda-developers.com/ga...om-resurrection-remix-n-sm-p600-wifi-t3606313)
Last year I replaced my battery with a new Samsung Original battery. But now i cant get the battery to charge to 100%. It always stops at ~45%.
If i check the charge current with the app Ampere it says maximum 450mA. It makes no difference which charger or cable I use.
Because of the loose fit of the MicroUSB connector I also replaced the connector unit.
Ampere also says that the battery is in good condition.
I also measured the battery voltage using a multimeter directly on the terminals of the two cells. Both cells had around 4.2V when the tablet stopped charging and showed a batterylevel of ~45%.
Is there anything I can do to get 100% and a higher charge current. Because now even if I plug the tablet into the charger the battery keeps draining while using it.

This is probably not what you're going to want to hear, but I faced the exact same issue and decided to power cycle the battery (drain it fully, charge it up to 100%). I got to the drain fully part and then it wouldn't charge anymore. I had tried the same thing as you with multiple cords and tried charging from a couple of different power banks as well.
My advice if you love your device like I do...buy another battery and keep it plugged in until you can swap it out with a new one. Once it hit 1% it was gone for good. This happens to me every 1-2 years...I've changed the battery in mine 3 times. Personally I think it's the OEM replacement batteries that are garbage. Next time I'm going to buy the newpower99 one and see if it lasts longer.
TLDR: keep it plugged in, buy a new battery, replace ASAP.
If you do get it working though I would love to hear your solution in case it happens again!
Well I did find a "solution".
It seems that the power management is quite bad on the Samsung devices, which means it has to be reseted from time to time. I could fix it partially by disconnecting the battery for ~10 Minutes and reconnecting it.
Now I got 75-80% charge and a reasonably charge current. But now the low voltage detection seems to be a bit off. At ~25% the screens stars flickering and it turns off after a short time.
I found this hint in the comments of a YouTube video about replacing the battery or charging connector.

I will definitely try that out thank you! Mine does that at around 10% and there are times the battery will say it's at 30% then drop to <5% in a few minutes. I just leave it on the charger over night now which I know isn't the best for battery life but at least it keeps it on when I use it
cheers
Battery management is voltage based. The Android Coulometer mainly has to filter short voltage drops caused by high cpu load.
If the Coulometer begins to show sudden changes in capacity and causes premature shutdowns, you can flash the coulometer firmware, if you're running stock rom. Reinstalling stock rom in Download Mode should also help.
There are only few sources on the net dealing with this coulometer thing and only for certain devices.
But if you do nothing, the capacity jumps will fade away with time. It took months on an old tablet of mine, but the period of time may depend on the time since the last full factory reset or system recovery. And my (and your) Note are older today than this tablet back then...
Then there's always real cable and battery isdues.
