Hello, I just got my 6500mAh battery and now I am facing a problem of slow charging. In fact, in the past, I am used to monitor the charging process using the Android Tuner app. Using the stock Samsung battery and the stock charger, the reported charging rate is about +50% per hour. However, when I switched to the external battery with the charger provided, the charging rate dramatically decreased to about +8% per hour.
Here are the spec of the hardware:
- Battery: 3.7VDC, 6500mAh, Li-ion 3.7V, rechargeable
- Charger: Input: AC100-240V~50/60Hz 150mA
Output: DC4.35V 350+-50mA
DC5.2V 800mA (USB)
And the setting in the Android Tuner app; in Android Tuner>Battery>Monitoring:
-mA retrieval method Automatic
-1% increment support: off
-measure on boot: off
in Android Tuner>Battery> Calibration:
- Battery capacity (mAh): 6500
- AC output power: 800mA AC charger output power, 5200mV AC charger output voltage
- Configure AC charger on plug: off
- USB output power: 500mA
- Calculate % from mV
And some setting in STweak:
in Power>Charging currents
- DCP AND MAINS AC INPUT CURRENT: 1800mA
- DCP AND MAINS AC CHARGE CURRENT: 1700mA
- SDP INPUT CURRENT: 475mA
- SDP CHARGE CURRENT: 475mA
- CDP CHARGE CURRENT: 1000mA
in Power> Charging current adjustments
- IGNORE 100MA STEP SAFETY MARGIN: NOT TAKEN
- IGNORE UNSTABLE POWER DETECTION: NOT TAKEN
in Power> Battery chaging voltage
- CHARGING HARD VOLTAGE: 4.20V
- CHARGING SOFT VOLTAGE: 4200000 microV
Other information:
Device: Samsung Galaxy Note 2 N7100
Kernel version: 3.0.36-Perseus-alpha36
ROM Version: N7100XXDMG1
ROM API Level: 16
ROM CodenameL REL
ROM Release Version: 4.1.2
Hardware Serial: 4df114C327f29fb1
Radio Version: N7100XXDME4
Android Tuner version: 0.9.11
STweak version 1.1
Any advice would be helpful!
Note: Just don't laugh if the setting looks funny since I am really not an electronic guy...
And by the way, I did an experiment in which using the stock battery, in STweak, I raised a bit the charging hard voltage to 4.35V and soft voltage to 4200000 microV, the speed was a lot faster. However, I am afraid that if I do the same thing with the extended battery, it would cause serious problem since in the app it says that the safe charging hard voltage for a 3.7V battery is 4.2V.

Hello, I recently got a 6500mAh battery and it comes with an USB adapter. The problem is that when I charge the battery with the adapter using an USB cable, it charges incredibly slow, about 10% per hour. However, on the stock battery, it charges lots faster using the stock adapter, about 50% per hour. Also, when I use an app called DU Battery Saver Pro from the Play Store, with the stock battery and charger, it says that the charging process is AC charging, but with the extended battery and the third party charger, it says that it was a USB charging. What exactly differ that two kinds of charging? I believe that the amperage matters...
Here is the spec of the third party charger and the battery:
- Battery: 3.7VDC, 6500mAh, Li-ion 3.7V, rechargeable
- Charger: Input: AC100-240V~50/60Hz 150mA
Output: DC4.35V 350+-50mA
DC5.2V 800mA (USB)
Recently bought a Choe 15W fast charger and when i use it, the battery recharges at 2.5A which is significantly faster compared to my samsung charger at 1.5A. I also read that quick charge 2.0 should not let the current to increase above 2A. Is this normal? The temperature is also higher at 44 degrees celsius compared to 41. I thought E8 should have quick charge 2.0 implemented based on gsmarena.
quick charge 2 works at 9V/1.67A
its not about the amps only
it means your charger is not quick charge 2.0
dont use it
Hi, i've just purchased Xiaomi mi 5 and i have question regarding charging the phone. It supports Qualcomm Quick Charge 3.0 however the charger that was provided only supports QC 2.0.
I notice that whenever i plugged the phone to the charger that supports Qualcomm Quick Charge, my phone gets hot. I decided to do a little test, so I used an USB Charger Doctor that can read voltage and Amp that it delivered to the phone. I've also using Ampere to monitor my battery temperature. I'm gonna charge for about 36 minutes using Aukey charger. It has 3 ports with only 1 that supports QC 2.0, the rest of the two supports up to 5 volts at 2.4 amps.
Here's the result:
9 volts, 1.35 amps = 56% battery charged from 8%. Battery temps reach 43,2 C. Juice added, 48%.
5 volts, 1.71 amps = 43% battery charged from 7%. Battery temps reach just about 35 C. Juice added 36%.
It's clear that qualcomm quick charge is faster than the standard port, however it resulting in higher temps. And i know the fact that Lithium batteries hate high temperature. So which is the best for battery life? Higher Voltage lesser Amps, or Lower Voltage Higher Amps? Thanks in advance.
Hi everyone. Today I was reading about battery charging because I play with kernel modifications (faster battery charging), for example, i have a Lenovo A6020, wich have an SM5414 charger (can be powered with 5V up to 2,5A), but my battery is 2750mA/h. So... This device support high current battery charging (i think is compatible with quick charge 2.0 technollogy) . But, the point is: Is good for battery (can be risk?) with high current? What is a acceptable current for charging these batteries? And for example, in HVDCP (QC 3.0), With 5 / 9 and 12V, this current incrases a lot? All these circuits have buck converters to supply a stable voltage (4.4V) and a variable (High current, 1,5A~4A in some models). In my kernel mods i also used arround 2,5A at buck output (charging current) and measured with ammeter in USB cable 2,05A (programmed at kernel drivers). Mi xiaomi redmi 4x has a SM1351 charger and support HVDCP with 5, 9 and 12V all with 2A maximum.
What is your S8 charging rate? (from 0% to 70%)
Mine is:
Fast charge adapter, fast charge on: 2.4A
Fast charge adapter, fast charge off: 1.6A
1A sony adapter: about 900mAh
Computer: About 500mAh
I tought "normal charge" with the fast adapter would use a lower rate. What do you think? I choose longevity (low current and low temp during charge, not going over 4.1v) over charge time, so i charge the phone to a max of 80% and at the lowest rate possible. I usually plug it in when i get home from work, and about bedtime is charged.
(My 3 year old Z1c still got 1 day battery until i broke the screen)
Fast charge adapter, fast charge on: 2.4A
Fast charge adapter, fast charge off: 1.6A

I think you mixed up your measurements.
Fast charge is 9V @ 1.67A (15W)
Standard charge is 5V @ 2A (10W)
