Hi all,
Does anyone know of any charger with improved charge time for the P8? I was looking at purchasing a quick charger such as the one below in order to improve P8 charging time, but I am aware the device is not Qualcomm quickcharge certified.
Aukey Quick Charge 2.0
Thanks,
Robin
Can a mod please move this to the Huawei P8 forum?
Hi, probably too late to reply to this, but may help others with a similar query.
I was looking for a QC myself recently for my P8, but came across 2 reviews (on Anandtech & Recombu) that said no matter which charger they used, it didn't make any difference.
Also, another review (Notebookcheck) said QC is not supported, so that should be the reason why.
The internal IC stabilizer for battery charging does not support fast charging. From the other side is good because this will conserve battery life...
I read that charger I got with the phone is quick charge and wears down the battery, I noticed it charges super fast and I've been using it for a few months now, but I plan on keeping this phone for a while, so I wanna preserve my battery, what kind of charger/adapter do I need to charge my le pro 3 normally? I didn't get anything else with the phone. I've got "input 100-240V 50/60Hz 150mA output: 5V 1000mA" adapter where I plug the usb cable into it and the other side to the phone and then the adapter in the outlet, I noticed it charges super slowly like 20-25% an hour or something, is that good? I don't really understand how these things work
Bump, still using this charger, I'm planning to order new battery from aliexpress so this is great time to reask this questions, maybe someone knows...

A normal charger that does 5v 2 amps will give your battery a nice, long life. The stock LeEco charger can go to insanely high power level which has caused the death of many LeEco phones. If you want a safe quick charger, dump the factory charger and buy a third party one from known companies like Baseus. I understand Baseus also have cables with built-in protection circuits.
Charging fast will not damage the battery. If the phone gets heated over 45C when charging that can shorten the lifetime.
But if you install LineageOS 16 you can disable quick charge and enable it when you need it, so you don't have to worry about chargers etc. anymore then.
I am not sure if it is wise to order a new battery. AFAIK you need to remove the screen etc. to replace it. It is a complicated process and you may end up with a brick.

I'm just considering replacing the battery on my daughter's le pro 3 - x720, It's a daunting task but it needs to be changed I will not be documenting the procedure but I will post anything I feel is relevant on the forums
(Once I find a suitable replacement battery)
I was studying this problem, people charge the phone with QC3.0 chargers and the phone stops charging, what really happens is that the zener diode that has the charging plate for security reasons (stabilizes the load voltage) Stop charging because the zener it's short-circuited (QC gives more voltage than it supports, is designed for 5v, there is QC of 12v or more). A possible solution is to cut the zener. (It works again but without voltage stabilization, it would be better to replace it but it is very complicated).
I leave some images for the one who has the problem and does not get the spare.
There is also a zener diode on the other side, on the motherboard, if cutting the zener in charge plate does not serve, check the motherboard zener.

Thanks!
Is this problem occur due to qc 2.0?
Thank you for the tip!

Processor support qc2.0 and 3.0 but hardware added by xiaomi not. Use 5v 2A chargers aka Qc1.0
How do you cut the diode?
EDIT: Nevermind, I just used a needle and used it to grind the diode in half. And it worked! Thank you!

question, do you used a QC2.0 or QC3.0 to burn the diode?

Can't really answer that question right now since I'm not sure. It was a car charger my brother bought, it was definitely Quickcharge, just not sure which version. I'll let you know once I check.

Is there any video guide to follow to perform this. My phone is not charging too, all of a sudden.

download zip with pictures, someone commented that I cut them with a needle, maybe @animeallen can guide you...
On the other hand, did you burn it with a QC2.0 or 3.0 loader? helps us to prevent, if you can answer the poll better

Not sure but QC 3.0 charger does not charge your device at 9V or 12V until your device too has QC 3.0 qualified hardware(QC 3.0 circuit or equivalent) and software(kernel).
Cases like yours might be due to QC charger quality, which one did you use?
There are many low budget QC 3.0 chargers available like Aukey , Blitzwolf. I have Blitzwolf S9, charge my RN3 with it occasionally. And also I use MI Powerbank 2 (not 2i) for everyday charging and it is QC 3.0 input and output. Cannot check if my Zener diode is shorted but no changes in charging till now.
Charger's QC specialized circuit determine how much voltage (5v or 9v or 12v) and also current (~2A @5v or ~3A @5v or ~2A @9V etc.) should be given to device after detecting phone's charging circuit. So low budget QC 3.0 chargers may cause voltage or current rise.
And for RN3, do not set current (in any kernel) at 2.4A (it will cause damage due heat which is main culprit in long run) , 2A is sufficient but kernels with some ROMs (like NOS 8.1 for me), it charges at 1.4-1.5A. In such case, you can flash other kernels for fast (2A) charging.
My Mi Powerbank 2 charged my phone at almost (2A) in RR, Lineage 14.1 , lineage 15, pixel experience 8.1 roms.
Now in NOS 8.1 it charges at 1.4A in average.

For me the chargers detect the snapdragon 650 and send more power, the zener diode must support 10w only( i think no found info), I have comments above saying that they were burned with chargers QC, I'm trying to determine if qc 3.0 or 2.0

i using NOS 8.1 with stock kernel and original MI charger 2A 5V, charging speed 1998mA from 10% to 50 % then slowdown to 1600mA aprox and 90 to 100% 600mA aprox
I activated 2.4A option in whatever kernel I used, but I dont rely on it too much.
Primary charger is HTC 1A, only use my Aukey QC2.0 when I need quick refuel. And my phone still rock stable though
Never burned mine out but I have a QC 3.0 charger and when I plug it to the phone it charges at the normal rate of 5v 2A, so I rarely use the QC port on the charger since it's the same as using the stock charger or normal ports, my guess is there are many custom kernels causing this damage, and I think there was one rare miui beta that enabled it at one time, I'm not sure if there is fake QC chargers but I believe real / official ones the circuitry is made by qualcomm and it does a series of checks to see if the device can support it or not-which it never did activate on my QC charger at least (I have a Choetech QC charger that cost around $30), which was pretty costly considering I never got to use the QC feature, but I think it's well built and never gives problems so in a way it was worth it and it's available if I get a device with proper QC support.

kernel can allow charger to pump in high current
many users have faced this
some carelessly do it knowingly
hence, AGNi limits it at max 2100mA no matter how badly users want to use QC currents.
Sent from my Xiaomi Redmi Note 3 using XDA Labs
i implimented a 4000mah battery into Yureka plus with keeping old battery's board fitted in new 4000mah battery , but backup is same as 2500mah !!
i even compiled a kernel based on AR_beast R9 with the changes in souce files responsiable for mah of battery and charge (just searched in git hub with term "2500") and changed them with 4000) and also changed framework/res/xml/power_profile with battery_capacity = 4000mah
where i am wrong ?
is there any special file which is responsiable for charge to give battery it's peek mah threshold limit ?
and also explain how to calibrate battery with the changes.
(inspired by video like this youtube_dot_com/watch?v=R2FVg548zsQ)
sorry for my bad english
Are you able to use this battery?
You should not use protection board from old yureka battery over new lipo pack. Which phones 4000mah batt are you using? Most lithium batteries(70-90%) sold in india are fake and hold half of the stated capacity.
The 2500 thing is just a label. The charging ic doesn't care what the label says. It simply continues to put charge current until voltage reaches 4.2v(for li-ion). The yureka charge IC maybe be charging till 4.35v because bundled battery is lipo.
Drain till 0% and charge back non stop. It should charge it full 4000mah
else
Use a knife and scrape off all traces leading to the main terminal pads on the yureka battery PCB. Then solder enamel copper wires from old PCB to new PCB. You'll have to place old protection board on existing board.
you are scamed

hello, i have also using 4k battery (bm47) on yureka, i modified the kernel to adjust the charging voltage and battery capacity according to bm47 battery. join this telegram group , i am available there, https://t.me/yureka
