I got a Nexus S the other day and so far impressed apart from one thing. I left the phone on charge overnight and in the morning it said it was only 96% charged. This was with it plugged into the mains charger for almost 8 hours with the phone on stand-by.
So I read on a thread somewhere you need to discharge the battery fully, then charge the phone with it turned off to correct this. So I did that last night and again this morning it says it's only 96% charged.
I'm also disappointed at how slowly it charges via the USB cable. Had it plugged in for a couple hours at work on my computer and it only went up by around 3%, this is shocking. I'm trying it again now on a different computer and so far it's only gone up 1% in an hour.
What is going on?
It's meant to stop at 95% - 96%
Leaving your battery at high voltage (100%) will cost the battery lifespan to shorten in the long run. So usually chargers do not charge it to 100% at all but slightly below it to lengthen battery life.
OK thanks for your quick response.
Regarding it being slow to charge connected to a computer, is that normal?
Are you leaving your screen on while charging? Because the screen eat alot of power, so that might be the case.

Nope, it turns off after 30 seconds. Wifi was also turned off.
Maybe try using SetCPU to alter your processor speed during charging and screen off to the lowest. It will significantly increase your charging speed.

I will give that a go. But really should this be something that I have to do, shouldn't the phone charge on it's default settings via USB at a decent rate?
It might be due to programs running at the background. I'm not sure. But my Nexus S charges fast enough though. Not as slow as you mention. Maybe try doing a charge after a reboot of your phone? If it charges faster after the reboot, it is most likely the background processes you had.

Yes it is. USB only supplies 500mA. Plugging into the wall is usually 700mA or 1A. Have you ever seen how long it takes to charge an iPad on USB? Its wall charger is 2A.

No because usb is only half power of regular wall charger, so it takes much longer to charge on usb. It's possible when using the phone during usb charging to pull more power than usb can provide, stopping the charge completely.

I also have this problems, but if don't use the computer usb to charge, it seems no problem.
Why does the battery take longer to charge while the phone is off?? the funny thing is i think it lasts longer when i charge while the phone is off, am i being paranoic?
I have noticed that it charges slower when turned off, but personally i see more battery life when i charge the phone when it is on.
Not in my case...It appears to be faster....
Charge via USB and it is slow.
Charge via wall outlet is extremely quick.
The phone trickle charges during the last 10 percent to ensure a real full charge. But it shouldn't matter if the phone is on or off.

Hi,
I noticed that when I recharge it with a charger that is only 650ma the battery last much longer than with turbo charger that came with the phone.
Even in standby after recharged it takes one hour to consume only 1% but after turbo recharging it takes about 10 min to drop 1%.
Is there anyone experiencing something like that?
Funny it is.... The case is opposite for me... Although I use Transomart QC 2.0 charger. My battery lasts longer when I charge it with quick charger compared to standard 1 Amp chargers.
That´s so weird.
I am preparing a comparison to figure out what's happening.
It happens the same here. I've a Aukey turbo charger and the battery drains faster

There's no way to actually know the charge (in mAh) of a battery without draining the battery. The way that phones estimate the charge is by measuring the voltage of the battery. Quick Charge 2.0 (supported by the Moto X 2014) uses a higher voltage to charge the battery faster. This can make the battery hit max voltage before it is actually fully charged. That is why Quick Charge always advertises how quickly it gets to 80%. To get to full charge (not just when it shows 100%, but when it is actually fully charged) will take about the same time as a standard charger.
Heat and Turbo charge destroys your battery.
if i turbo charge , my phone will suddenly die when it's between 10-20%. W/ regular charging I get sudden death at 6-8%
i use a moto razr 850mah charger and solved the 8% sud power off, took 2 charge cycles from death to 100% leaving it overnight. Now battery works as it should
.
As I've been reading around (can't recall specific scientific data), the faster you charge the battery, the less capacity it can hold. So it makes sense that it lasts longer if you charge it slowly. I don't know how much would be the difference tho.
It is normal in my opinion. Slower charging is also healthier for the battery and usually will last longer
Has anyone ever used a wireless charging pad with the phone. I bought a stick-on one from amazon and it charges fine,,,slower but fine. However, I noticed that it tends to get suck at certain levels and if I take off the wireless charger at say 89 percent,,,it takes less than a min to go to 100 percent charged?
Recomendeed is charge with Motorola original charger of this device, i mean 1150mAh dual port charger
Anyone here with experience of using Motorola's Turbopower 15 wall charger? I'm thinking to buy one, because waiting for 1 hr to charge to 100% is quite annoying.
Sites say that we should keep our battery between 40-80% because charging battery to 100%(And losing till 5-10%) can degrade the capacity of battery.
But Company representatives says that we should charge till 100%.
Can anyone please tell me that till how much we should drop our battery and till how much we should charge it?
Companies like Toshiba and Samsung, have a feature with their laptops to assist in prolonging their laptop battery life called 'Battery Life Extender' which stops charging at 80%.
It is supposed to prolong the life of the battery by avoiding over charging.
For smart phones we have
Quick Charge, Fast Charging, Rapid Charge and other names haven been given to this technology. With the HTC 10, the large 3,000 mAh battery essentially can recharge from 0-80% in just 35 minutes, then it trickle charges the remaining 20% to preserve battery life. The entire phone can recharge from 0-100% in around 75 minutes.
Smart chargers will stop charging at 100% where as computer USB ports 500mA and basic cheap chargers (500mA-1000MA) will keep pushing power to the phone. These should not be left on the charger overnight.

They say that you should not deep drain your battery, but getting to 0% is not a total deep drain. I get down to self shutdown once a month and perform a 100% full charge to calibrate the battery and % markers.
This has allowed my HTC M8 to run well for almost 4 years.

So, exactly how much you drop and charge?
Hi Yash24,
I top up my phone in the morning 1.5hrs before I leave for work and finish off in the car.
Im close to 100% and then top it off again on the drive home.
This usually is at 10-15%.
Hello!
It's been a while since I don't have an Android device (Iphone user lately) and I'm buying this beauty these days.
I have two questions: First, right now the 45w charger is out of stock so should I buy the 25W instead just until I find the best one (expend money).
Two: How shall we charge this device? All night? Just 2 hous like Iphone? Please help me out on this.
25W vs 45W is really just a matter of the time it takes to charge the phone. And right now, available evidence suggests that its not worth it. As for how to charge it? All night is fine, as the phone will stop charging the battery when it is fully charged.
does the phone will stop charging the battery when it is fully charged?

Yes, that is always the case.
I would recommend buying a 45W (or higher) USB PD PPS power supply. That will work on Samsung devices. But keep in mind: it has to support PPS to allow voltages between something like 5V, 9V, 15V etc. If it is only USB PD, it will only charge at 15W.
I have the Anker Nano II 65W that has PPS, but there is also a 45W version. But that is just one option, there are plenty of other products out there that support 45W USB PD PPS

LAtest equipment come with a battery health function it basically charges fast up to 80% and then slowly charges the remaining 20% to extend battery life. Once at 100% it won't charge at the same level, reducint the current/voltage.
I really don’t want to damage the battery like it happened with my iPhone (1 year and 89%).
That’s why I’m asking!
Please post your own experiences.

The worst thing for mobile phone batteries is heat. So running the display all the time and gaming are probably the things to avoid. Which unfortunately...Is what most phones are being designed for these days. So don't let the phone get hot, and try to keep the charge level under 80% if you want the battery to really last. But batteries WILL degrade. There is no way around that. The best you can do is try to limit the damage.

Two things kill the battery: heat and high/low voltages
In an ideal world, the Li-ion battery is at around 20°C and stays at around 3.8V.
Use the slowest possible charger whenever you can (5W e. g.)
Avoid fast charging as often as possible
Don't charge past 80% and don't let it drop below 20%
Don't let your phone stay at 100% for too long. Nothing will happen but the high voltage will degrade the battery (like if you leave your device plugged in every night).
In theory you shouldn't charge your device when it's hot and so on but I mean if you live in Spain for example and it is summer. What else are you going to do? So avoiding charging the ambient temperature is too high, is something you can't really do. (Yeah, in Spain most homes to have AC but you get the point )
I have taken care of my OnePlus 7T Pro's battery since I have received it 2 years ago. According to OnePlus Diagnostic it started at around 97% health (new device) and is now at 93%. I almost never charge above 80% and have a Tasker routine to only let it stay at 60% over night and charge to 80% right before my alarm rings. I use ACC (Advanced Charging Controller) for that. But it requires Magisk.
That might be a bit extreme but I have only lost 4% after 2 years and countless battery cycles. Keep in mind that every now and then you should go from 0% to 100% to let the system calibrate the battery so that it accurately reports its charge. This is the only reason why you should do this so that the system knows how much capacity the battery has. And if you mostly stay between 20–80% all the time, it might think that 80% is its max charge and start misreporting the percentage.
Thanks for all that great tips. I think I won't ever buy an extra fast power charger, I'll use a normal one...
is it safe to use 25 watt charger of s 21 TA-800 for charging s22 ultra?
