Running Synergy Rom stock kernal 15 toggle from AT&T
Ran phone till it died last night, didn't start it back up just plugged it into charger, got empty battery pic, went to bed got up 7 or so hours later and phone was only at 84% ? Another odd thing is the way it shows the charging curves on the battery stats graph. https://www.dropbox.com/s/mupjhqpxl5nhg1b/Screenshot_2012-07-26-08-37-42.png
Anyone have any ideas or have the same thing happen
EDIT:
Think I may have figured out the only charging to 84% problem. I forgot I cycled a new non Samsung battery into my phone. Samsung has adopted a 3.8v battery were as most other phones use 3.7v the aftermarket battery is only 3.7v so I'm guessing its not showing full charge because the battery is never making it to 3.8v. As for the odd stats on the graph I'll see if the Sammy battery does the same thing the next time I kill it. Its my understanding that the batteries have their own overcharge circuitry so I'm guessing generic wall chargers will still charge the Sammy 3.8v batteries to the full 3.8v and not 3.7v the chargers I have also lack a voltage rating so I'm again guessing that that is because it is regulated by the battery itself.

I just got my Extended battery and im trying to charge it fully but it wont charge past a certain point. While Plugged in i can watch it discharge slowly. Anyone with this battery have this problem?

I would charge it first time with the phone off, and then wipe battery stats to be on the safe side.

perhaps it has to do with the fact that the battery norm voltage is 3.7 instead of 3.8. full charge voltage will also vary too. Anandtech did an article on one of motorola phones.
hyperion batteries also has a integrated chip that prevents overcharging beyond 4.2v (which is 100% for 3.7v batteries), 3.8v batteries have higher full charge voltage. 4.35v i believe.
Mine charges 100%. I did charge it the first time with the phone off, but I don't know if that matters or not.
I love that battery with the Hyperion extended case.
My phone current input is fixed on 50mA, tried different chargers but still it is fixed on 50mA input. Is it the battery or charging port issue? (My battery only lasted for less than 2hours when its fully charged)
Did you check the battery if it's swollen or not?
The battery size is normal. Its not swollen or bloated.
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%.
Good night,
My Nvidia Shield barely charges at this point in time, shows like 16h to charge and more...
I have desoldered the battery and charged it with IMAX B6 up to 4.2 Volts and got around 3000mah but the voltage is still being held at 4.2V good.
Do you know if this is normal behaviour when the battery is already a bit bad or do you think the charging circuit can be bad?
I'd be pissed to buy a battery to find out the charging circuit is barely putting any charge

Did you keep the PCB strip from the old battery on the new one ?

I didn't buy a new battery yet.
I would only buy one if I can be sure the tablet charging circuit is any good...
But like I said I charged the battery externally to 4.2V and the next day it still had 4.2v so it doesn't look like the battery is completely bad as it's surely holding voltage well, just lost quite a bit of capacity which is normal.
I'm thinking that the charging circuit of the tablet is kaput...
