Running a rooted, unlocked, EVO 4g running CM 7.2.0 Rom
I've seen this same behavior twice. Once yesterday and once today.
Yesterday
Phone was plugged into usb port of laptop charging (around 50% at the time) was running Pandora and Wifi Tether (build into ROM). Phone crashes to off, no reboot attempt. Attempt to power phone back on yields no result (no lights, no screen ... nothing). Remove battery for 10-15 mins, insert and hook up to a AC charger and hit power button. Red light starts flashing, I wait for it to turn solid and try booting again. This time phone turns on and hangs at white HTC EVO splash screen. I then boot phone into custom recovery image, clear cache partition, and reboot. Phone boots ROM fully, batter reads 50% still and works fine until the next day.
Today
Phone was plugged in running Wifi tether, but not Pandora. Same behavior in crashing, removing battery, hooking up ac charger etc... this time however it didn't hang on the HTC EVO splash screen, and boots the ROM. However, the battery no reads 0% and wasn't charging. Removing the AC charger causes phone to shutdown. Reboot rom again, still read 0%, but let it sit for a few minutes and begins to charge. Appears to be charging fine and holds its own without the ac charger. **Note - battery was also around 50% or so when it crashed out
Questions:
Whats the root here? Bad battery? Bad rom? Thoughts on root cause would help if anyone has gone through this.
Thanks!
I'd say a combination of battery and ROM. Try flashing a new ROM and if it continues, try a new battery.
hi, I am on Dr.Ketan ROm v12. from the past few days my phone constantly reboots itself till i connect to AC power. The phone reboots again constantly when the AC power is disconneted.
I thought it was a battery issue, however, the phone stays ON in recovery mode ( till the battery drains to 0% )
It may not be ROM issue as it works fine on AC power.
I have to connect the phone to AC power constantly to use it
Anybody with any suggestion, please help. !
I have H818p on Marshmallow, everything stock. Yesterday i used the phone until battery goes very low i.e, 3 %. After that some strange things happened, at 2 % battery remaining , it stopped calling feature and then turned off. Later i charged it and turned ON again, from that time i am facing these weird issues, details are as :
1. No more connection with Laptop for data , only shows charging, and there are no options to change it.
2. Charging of phone stopped. now nothing happen when connect to charger. Until i reset the phone everytime after connecting charger then it starts charging. But also Only upto the time until charger is connected. If once i remove it, then again needed to reset phone to start charging. It seems phone pick charging only when its Off. also until its connected with charger.
3. very slow charging. whenever charging start, its very very slow. taking 5 hours now on Original charger.
I was a die die hard fan of LG, using from G Pro to G2, G3 and now G4. but these issue really annoying and changing my mind from LG. Please help me to solve this.
I had almost the same problems a month ago and they started from nowhere (slow charging, no connection with PC). I tried cleaning the port that didn't help. As strange as it sound all problems ware gone when i flashed a fresh KDZ with LGUP. At first my PC wasn't detecting the phone in Download mode so i tried like 10/15 times and it installed the drivers eventually. So yeah ... go figure ..... i hope this is helpful
Try replacing stock battery or stock charger/cable or the poster said about flashing fresh kdz via lgup
Hi my phone has been shutting off randomly at 20%ish for a while now and last night it shut down randomly again. but when i got home to charge it, it keeps restarting at the recharge logo and when i powered it up it still keeps restarting. I have wiped the cache partition and nothing happened.
Try with a new battery, you might have a damaged one.
Okay so, my LG G3 has had a problem with restarting and bootlooping before this. Basically, it would restart if used while not plugged in and would not boot up if not hooked up to a charger. Before this, plugging the charger in would solve the boot loop issue, but now, that leads to a different issue.
So, I was using my phone (while it's charging) and suddenly - screen goes black. After a few seconds, the battery loading screen (an icon of a battery with a small circle with several spokes in the middle of the battery icon) pops up. I hold the power button and the LG logo pops up and then goes back to the battery loading screen. which just bootloops if left alone.
Now, the phone CAN boot into recovery and bootloader (although it sometimes fails, it's like the device restarts mid-way through). In TWRP recovery, it shows the battery at 100%, although after rebooting into recovery again after some time, it displayed 75% (i never took the phone off the charger).
Sometimes while in recovery and the device is not plugged in, it'll restart, but that's kinda... normal, I guess, it used to do that before.
My PC recognizes the phone and I can access the data on it via USB without any problems.
I'm almost positive that the battery is the culprit, since a few hours before this started happening, it drained 20% in 5 minutes and in general, after it restarts randomly when not charging, the battery goes from 100% to 90% and if restarted again goes back to 95% or something like that. But does anyone have any idea how to fix this? I won't be able to buy a new battery for a few days and I need the device in working order until then.
