new battery pack needed for Nexus 5X?

[chubby]

hello, I have a Nexus 5 and a new Nexus 5X, I just noticed that the Battery pack that charges the N5 (micro USB) fully, will only maintain battery status but not Increase and fully charge a Nexus 5X, while the N5X is running, so I guess I need a new USB C battery pack , quick charge?

anything someone might recommend? if so

[mtls2005]

Does the 5X fully charge via its ac adapter?

 

What is the battery pack make/model?

 

Did this pack ever fully charge the 5X?

 

Not sure if the best brands are available here but Xiomi's Type C products get generally favorable reviews.

 

This model specifically: http://www.lazada.co.th/xiaomi-mi-power-bank-pro-10000-mah-with-usb-type-c-quick-charge-6028800.html

sure the 5X charges on a/c,  the pack i bought for the N5 and it charges it up, but only maintains the N5X ...... 

seems the quick charge USBC on the 5X requires a pack made for it , from poking around on amazon.com

[mtls2005]

But this older power pack will fully charge your N5X fully if you turn the N5X off? Yes, or No?

 

My guess is that the current firmware bypasses the battery charging circuit when the phone is plugged in to a charger or pack, and the phone is on. Just a guess. If so, no power bank will do what you want.

 

will only maintain battery status but not Increase and fully charge a Nexus 5X, while the N5X is running

 

This may be a feature? And with root access and a custom ROM you could probably change this setting, but not sure what the ramifications would be. My guess is LG did this on purpose.

when the  N5X is plugged into the battery pack it says  "charging on a/c"  but checking the graph, it will never increase in charge, only maintain charge. 

 

i'm guessing I need somethign like this :

OK, Ill ask a second (and last) time...

 

When you turn off (fully power off/down) your Nexus 5X, and charge it using your current power pack, does it fully charge the Nexus 5X?

 

and a bonus question...

 

When you turn off (fully power off/down) your Nexus 5X, and charge it using your AC power adapter, does it fully charge the Nexus 5X?

 

 

[chubby]

as a matter of fact, it DOES fully charge if it is powered off via the  Battery Pack 

 

 

via the AC adapter it charges fully when turned on, is there some reason to test it when it's turned off, via AC? 

[chubby]

why would they design a phone that can't be recharged by battery pack when on ?

My guess: probably safety reasons?

 

If your device is in use while charging, the heat from all this may trigger the kernel to throttle and eventually completely stop charging for safety.

 

Plenty of reports on this phenomenon on power-banks, AC and even using car chargers.

 

It might even be mentioned in the user's manual?

 

My second guess is that the spiffiest power-bank in the world won't alleviate this issue for you.

[chubby]

hmm, guess i will just have to charge while turned off.

though , i do note that the new charging system went from mini usb to usb-c (fast charge) ; and seems to me many people charge their phones with the phones on. 

and they do market some powerbank as usb-c friendly, whereas in my case i had only used it with microUSB, which did charge the N5 while N5 was on .......

 

 

[mtls2005]

"hmm, guess i will just have to charge while turned off. "

 

Maybe turn on the AC? Put it in the fridge?

 

 

Further research seems to definitely point towards thermal throttling designed into the kernel. This is done for safety reasons, to prevent the unit from getting too hot among other reasons.

 

As I said in post #4, "My guess is LG did this on purpose."

 

I guess you could fiddle with the thermal throttling thresholds; if you see smoke/flames maybe turn it off?
