Hi guys!
TL;DR at the end.
After posting on here a while back, asking for advice about the Epic 4G touch, I decided to buy the phone.
However, i'm having a problem. One of my biggestt decisions to get this phone was that, as far as I could find online, the phone was equally good at 4G as my old EVO and capable of doing WiFi hotspot without too much trouble.
Last night I got my new phone, set it up, rooted it, installed CWM, and then set myself up with the Blazer ROM, which I really like.
Blazer comes with the "sprint hotspot hack" so the builtin Hotspot app works fine.
Yay!
Except, it uses battery even faster than my EVO Did. with my old EVO, I could hook up the phone to my laptop via USB to charge it and use hotspot at the same time. It would still maintain 100% (roughly) charge even while broadcasting the wireless network, as long as it was plugged in.
This is not the case with 4G touch.. It steadily loses battery while using the HotSpot, even while charging! this is unacceptable as I use my hotspot for hours at a time.
What can I do? Is this an issue with the blazer ROM? Is there something I can do to make it charge faster? ?Use less battery? Would using a 3rd party hotspot app (like WiFi tether) consume less battery?
TL;DR
Hotspot uses too much battery even while plugged in and charging. What do?

Is there no way you could you the AC charger do you have to use the USB? Also try placing you phone down screen first and taking the back cover off to allow the access heat to escape.
Have you tried USB tethering instead? Dunno if that is unlocked in blazer or not..
If bringing the adapter with me will make the difference, then I will start doing so
I tried out using the Wireless Tether app instead of the built in sprint hotspot, and I noticed that the Wireless tether app uses less power (so it charges while on USB instead of losing power) and also generates less heat... However it wont let me use any security protocols. If I do so, then the tether has errors and fails.
So it seems like i'ms tuck between a rock and a hard place..
Barnacles, I can't rely on the USB tether. I need it to be WiFi. T be honest, my 4G is my primary internet, even at home, so I need it to be wireless capable for myself and my boyfriend to use at the same time
Also wait a few days for the rom to settle in so you can see the full battery savings effects. also use setcpu or tegrak and Underclock/undervolt during this time and you should be fine

AC adapters usually charge the phone faster so I would recommend using those

Make sure the power rating is 1A, 5 Watts. Some are 500 or 700 mAh (even though they may be Samsung branded), those are insufficient for our phones.
LOL what kind of boyfriend leeches his internet off his girlfriend's 4G tether setup?
Tell him to get you some legit internet service
Thanks, phatman! i'll make sure i get the proper voltage.
@LordJummy: We live separately, but when we're together we both play games. So I need to have it on WiFi so we both have access. I can't afford to pay another bill on top of what I already pay, and sprint has never *****ed about my tethering, sooo.. im gonna keep using what works.
Usually the output amperage from a computer usb port is .5 amps. My suggestion is get a usb charger (for car or house) that is for the apple ipad. Those are high amperage output chargers rated at 2.1 amps. I used a standard charger while using the phone and noticed that the charger couldn't keep up with the demand for power for charging and using the phone at the same time. I got a charger for an ipad and now it can charge and I can run the phone at the same time no problem. Here's some links.

Hello Friends:
I am on Jedi Mind Trick 6/21. I cleaned wiped the phone to reinstall 6/21.
My phone does not charge with most USB cables. For some, all it does is slow down the discharge. I can only charge with one cable I have.
I did not have this problem when I first started using JMT, and did not when I wiped and flash, so I suspect it is a software issue.
I took the phone to the store and they said the port is physically fine.
Thoughts?
Battery? Cables, obviously? The wall plug? Its not the rom I'm sure.

battery charging problem...
I too had that problem which may or may not be related. Nonetheless, I was not using jmt but with other roms and versions(4.2.2, 4.3, 4.1 2) and had the same issue.
To figure out what was going on I found an app from the play store to tell me how exactly how much mil volts I get from the charger cable dynamically(consistently).
I also double checked all settings that could drain battery from the device ie. gps nfc, etc..
During looking at the settings I found that nfc was on somehow! Other settings showed google services had the gps polling my location frequently causing drain. Lastly, while checking wifi advance settings found a setting that just kept the wifi checking for connection continually.
Unrelated but worth mentioning I switch Roms regularly with full wipes btw Roms which could be why the settings were funky...
I thought it was my battery going bad however; I had bought a OG battery a while ago so I popped that in and had same results ie. draining while charging. The charging app told me I was getting low mil volt from certain cords with the same battery-wort ranging from 900mlv to 40mlv.
What I think is going on is that:
1. the cord has to stay in the micro usb port
2. not all cords are made the same.
3. I think the micro usb port is A) has a loosen solder contact B) dirty connection in port C) 2yr old phone with a lot of use.
In Summary, I use the app to make sure the power supply is putting out..hehehe, ahem cough cough and that the cable is connected securely, cough cough... So a solution is to fix the port with reheating the mother board and soldering(risky) or sending it to get repaired(slightly less risky). I also, don't really want a new phone because I believe the T989 is a great device however, either a N5, or SGS4 would not totally unheard in this scenario. Sorry, for being so long-winded.
Sincerely, Jahman

Heh, I'm going to do a wipe and see if it charges on all of my chargers OK.
I've tested all of the same cables and chargers on another phone, and it charges just fine, so I know it's not the cable and charger
So charging is extremely slow now: max 280mA showing in Ampere app. Tried different cables and chargers(QC3.0 certified), charging speed remains the same.
I can't connect to PC anymore. Windows doesn't even make a sound when I connect the phone to PC. Showing no device.
Headphones connected to USB port are playing only one audio channel.
I've been using LOS 15.1 since last summer without problems, haven't done any updates since. The problem with USB port emerged a month ago and I am almost convinced it's a HW issue. AIDA64 indicates no temperatures over 36°C in thermal section so sensors are working fine I guess.
Anyone tried these charging ports from Aliexpress? Comments indicate that they are not the same as the original.
It really sounds as hardware problem. I asume you already tried with the phone off, and after factory reset and the problem persists.
In my experience, the original lower board have fuses which are expensive and are replaced by resistors on chinese replacements. If you dont want to lose this, try going into a repair shop and have the USB-C port replaced or desoldered/resoldered from the board. Must be done by experienced guy or it will be melted.
I'd buy the replacement board anyway. As long as you don't use crappy chargers, you shouldnt need the fuse too much, and also, the phone have another fuse in the motherboard.
If you have not tried with the phone off, try it. I got the xiaomi wireless charger and it works like crap with the phone on. it disconnects/maintains chage/stops charging A LOT, but if I charge the phone turned off it charges without issues at full power (8-10W according to my USB meter). Maybe is just the firmware being an ass
Thank you for insights. I confirm that hard reset nor charging solved the missing QC3.0 functionality. It's clearly a HW issue.
The whole situation was caused by losing my original charger on a trip and then using certified QC3.0 charger (not from Xiaomi) and unfortunately - cheap Chinese micro USB C cable. I can't stress this more... Never use cheap cables (or chargers) they can literally fry up your port. In this case it was definitely the cable eventhough it worked fine for 5 months.
It seems (from comments) that beside fuses the charging ports from Aliexpress are missing the possibility to transfer data over USB as well. Which is not that crucial because FTP over WiFi is bearable. The real problem that I need to fix is quick charging because with 280mA on Ampere app it takes 5 hours to charge this phone.
The charging port I've bought on Ali is on its way so I will update this thread in a few weeks after inserting it into the phone.
Losing data over usb is quite a problem if you are into custom roms/mods on native miui (which resets the recovery on each update).
Hope that ali's board does have this funcionality. About charging, you can get locally a wireless charger for now, though for me it only charges fast when the phone is idle, using it always just keeps the charge (probably to avoid overheating).
So how the story ends? We're you able to solve the problem?
I had the same issue with my Mix 2. bought a replacement port from Aliexpress and Witrigs.com. As posted on most forums these replacement ports don't support fast charging (in most cases) and no USB data transfer (this is the case with mine).
I had dropped a message on the witrigs.com website to confirm if their supposedly 'OEM' replacement supports data over USB (it looks much more like the original board in the phone that the 'custom' replica one that is half the price).
but I'm not very hopeful of that being the case, given someone has already left a comment on the product page indicating they bought the OEM version and faced the same issue with no quick charging or USB data transfer
Got some problem when i lost my usb travel charger on a trip.
and now my phone was too slow and cant transfer data even if i buy the new authentic from xiaomi store.
i hard reset for 3 times and but no luck.
omg -___-
I know it's old, but I'll let you in on my problem.
I have the Mi Mix 2 and it was happily fast charging until recently. Still the original plug and cable
I have tried all sorts of theories to get it fixed and one person said to charge it while turned off
So I plugged in my usb cable and turned off my phone. Only for it to automatically fire up and go into fastboot. No charging. Just fastboot on the screen
Obviously I can get out of fastboot mode again, but is mine an option change in the settings that needs addressing?
Thanks
M:y phone is sitting in the official samsung wireless fast charger (the stand up one for the Note10+) I am also using the official cord and charger. With the phone fast charging in the holder I plug my chord Hugo 2 (an audio DAC, it doesn't charge or draw power at all) into the usb-c port and the phone reduces the charging speed from fast wireless to normal wireless. This dramatically slows the charging rate. The problem is entirely software based so I believe there is some sort of package I can disable to prevent this. The phone believes I am using the charging port to charge it or some other device but I am actually only using it to send digital data to the DAC. I have tried changing the settings for USB devices in developer options (transferring files, etc) but no luck. Thank you.
I need a fix too. Anything yet?
maybe it is just like that because it thinks it will overheat... on the lg g4 it only charged faster when it was not picked up or moved and i think screen off. well the screen was off when i used the watt meter

I spent sometime looking and I have not seen nor encountered any package you can disable to do what you want to do. Charging functions like that are gonna be android system files, and things like .dll, .sys, .cfg and etc. This excludes any form of hardware components that monitor, limit, protect and control charging.
To be honest circumventing the charging functionality on the phone is a potential recipe for disaster.. it's not fast charging for a reason. It could very well be a safety precaution to prevent damage or overheating.
When I read up on the device the DAC might be trying to draw power from the phone via the USB connection. I get the same thing when I plugin a USB-C to HDMI adapter into my phone, and the adapter is obviously drawing power. Even though one would figure it shouldn't be since it's just a little ol' adapter something, it obviously is because it does get a little warm to the touch. So I wouldn't discount the notion that the DAC is drawing power in some fashion, because the phone isn't throwing that charging message for no reason.
Try making sure the DAC is in desktop mode (or equivalent) when you use it, so the device is drawing from it's internal battery. You should contact the company that made the device and ask them for suggestions/ideas. It maybe as simple as getting a specific cable, a compatibility issue with the DAC or what you do when you plug the DAC into the phone. It may just very well be that there is no solution and this is how it will work.

Comprehensive and concise in your hypothesis. Thank you. Most likely something they took into account with any adapters. Going to do some other testing too.:highfive:
My phone does that when using a USB hub with HDMI, it does work with my friends S20+
What can it be?

Dex needs a Knox-App called "KnoxDesktopLauncher" in /system/priv-app/. Make sure its on your device. Maybe you have deleted it.
Not sure if related, but today I noticed similar issue on my regular S20 with USB-C earphones, they kept connecting and disconnected, which resulted in media pausing, and audio playing through loudspeakers. Wiggling USB plug gently, and phone recognized earphones, only to lose connection shortly against.
Gently Wiggling USB connector in all directions, including pushing it deeper, and pulling it towards yourself, reproduced the problem everytime, which leads me to believe the USB-C port is broken.
This is strange. My phone is just around 4 moths old, I very rarely use USB-C earphones, and last time I checked (around a month ago), everything worked fine. The only thing I plug on a daily is a charger, never in a car, or in any place where port might be stressed.
The reason why I noticed this issue only today, is because I wanted to listen to some music, and had AKG USB-C earphones laying close to me.
USB-C charging cable managed to break the port, in such a short time, just wow.
By the way, charging works fine, USB is acting up only when data transfer is involved.
So check with other USB-C devices, maybe your port is also broken. Plug bundled AKGs, play some music, and wiggle plug gently, music will pause if connection lost. Also you'll see headphone symbol flashing in and out.
I think people might not notice this issue, because pretty much everyone I know switched to wireless, so this can remain unnoticed for months, or longer.
And what's the case with root? I've rooted mine with magisk and since then Dex only connects/disconnects... Is there any option to get it working on a rooted device?
Same problem here, not Dex (i don't use it) but with charging.
It keeps connecting/disconnecting while charging if I move the cable. Really annoying.
It sometimes also charges slowly or not at all while it does say it is connected...

I think our phones have broken USB-C ports, and also, after reading many reports, starting to believe that S20 series phones have a weak port design. I'm very gentle with my tech, so at least in my case, it's either manufacturing problem, or a bad port design.
From what I gathered online, first symptoms of a failing port are problems with anything data related, like in my case, USB-C earphones connecting/disconnecting causing media to pause, then problem becomes more severe, when it's not just media pausing, but phone losing data connection entirely, resulting in complete connection loss to a peripheral, when you have to wiggle plug to reconnect, only to lose connection again shortly after, and finally, these data issues lead to charging issues, like ones you describing, connection loss to a charger, appearance of charging.
I still have around 20 months of warranty left, but sadly right now need my phone badly and have so much data that I need to back up, so warranty is not an option, at least for now, I have to buy wireless charger, in case USB-C port fails entirely. S20 keeps disappointing me.. Sigh.
