i wanna directly use powerbank instead of battery. or by pass battery to directly run mobile.
current battery is damaged/swollen and even if i buy new battery which im finding it difficult to find the same, it will eventually be damaged soon as connect the mobile to charger for using it as a hotspot.

Below are the details of the mobile
Cyanogen Version YU5010
Battery 2230 mAh 3.8V 8.37Wh.
Charger output 5V 1500mA.

Used Ampere App to determine the below details.
on battery (damaged) current – min 140mA max 260mA & voltage – min 3.9V max 4.3V.

as i understand the mobile reqs 3.8V and 100-500mA (not sure & confirmed).
also im unable to find any power bank with 3.8V and 500mA rated output.
so i need to use step down converter to step down voltage from 5 to 3.8 and current from 1A to 500mA (assuming im going for power bank with output 5V and 1A).
also stepping down efficiently without more power loss.

let me know if u have ny knowledge/idea or u have done similar like this or any other way to run the mobile without mobile battery.
also let me know if wanna know any more details.
-————
dongle is not a solution coz i need to make and receive calls also.

Redmi devices have this great feature of charging directly from the AC Mains once the battery is fully charged. They are ideal for using as hotspots. Plus with root one could set the battery to charge to only say 80% which considerably aids it’s longevity.
If Yuphoria also has this feature you could buy a an inexpensive 3rd party battery and charge it from the power bank. Yu devices AFAIK have decent development.
P.S. While the charging behavior is similar to laptops I don’t think they will work w/o a battery.

The peak charging current for most devices w/o Quick Charge or equivalent is around 2000mA. Even my old Nokia with a mere 1020mAh battery charges at 800mA. I think you got your info wrong.
Edit: It supports QC 1.0. Anyways a degraded battery…

was not aware about redmi charging feature. is it there in all devices like redmi 7a/6a/5a?

actually my battery got swollen and damaged coz i used to plug in continuously for long hours. so i think even the new battery will surely get damaged. so was thinking if i could use powerbank as battery + it would run even when there is no ac power.

P.S. While the charging behavior is similar to laptops I don’t think they will work w/o a battery.
but many mobiles earlier works if we give direct power to battery connector pins inside mobile.

ok ur talking abt charger but what abt the drawing mobile operating current from battery. it varies upon the mobile state. i cant feed 1A directly (to battery pin connectors inside mobile) orelse mobile will get fried.

edit. in the main post i have mentioned the yuphoria charger which was supplied with the box. which is 5V and 1500mA.

In supported devices, once the battery is fully charged, the devices bypasses the battery and directly draws current from the charger just like in laptops.
The battery will not draw any further current neither will it discharge as long as the charger is connected.

Even the old Redmi 3s and Note 3 had this feature. You can search in this thread : https://forum.xda-developers.com/android/apps-g... or in the device-specific forums.
The trick is to limit the charging to a lower value. That way it will operate at a lower voltage. For long term hotspot use maybe set it at 60% which is what used in satellites and military equipment. Li-ion batteries have a finite no. of chaege/discharge cycles. Best to keep them in a 40-80% range. You can charge them any no. of times to no detriment.
Just install the app in Yuphoria assuming you have root and check if it works. There are several modes available. Just give the thread a read.

So bro ideally we should charge our phones as soon as it drops down to 40% and then charge upto 80%? Doing this extends the battery life?

Ideally yes. Lower operating voltages. Temps are another equally important factor.
My ~3 year old Redmi 3s and Note 3 provide nearly as good battery life as new. Small sample size I know but still…

Rooting Yu devices should be pretty trivial.

@LIMBO bro sorry forgot to mention that the micro usb charging connector in the mobile is damaged i.e. its loose and have to try multiple times to power the device (using the current swollen battery as mobile wont power-on without battery). so i was thinking powering directly with power bank would the best solution in this situation.

That puts a big spanner in the works. IIRC YU devices were just rebranded from Chinese ODMs. In case the USB port is on a daughter board separate to the motherboard as in RN3 both the board and the battery probably could be sourced from Aliexpress for cheap.
P.S. Don’t have any idea about directly powering of off the power bank.

@rajrocks you can redeem your dimes for Galaxy Note 10 now.
I know this isn’t the solution.

Thanks
Does using phone while on charge affect the battery negatively? Coz I use it a lot while charging

Not more than usual as long as the aforementioned feature is supported.

im aware of this bro and this is only step down voltage regulator and it doesn’t regulate current. i need to step down both voltage and current from powerbank rated outputs and preferably with lowest power loss.

the mobile is perfectly working fine. the only issue is the battery and my req is to plug in the charger for most of the time which will kill even the new replaced batteries.
300 where and when did it come?
