Hi, Sorry for my english

I mounted It without hardware or software mod.
The time to switch is set to 30sec.
When i turn off my car key appear the messenge it's shutting down and screen became Black. If i push the button it seems off.
But after some hours if i switch the car key:
50℅ times it turn on normally and so it load the s.o
50℅ times it turn on to home screen directly in 1 sec like it didn't be turned off previously
Any ideas?

30sec?
So, any time you leave the car the unit should boot up?
Set mine to 30 minutes. Maybe test another time setting.

Ok i Will try more time

My radio when engine shut down, the screen goes black and it takes 30 to 40 sec to completely turn off.
If turn on the engine befor 30 to 40 secs after shutdown, the radio dont boot, only turn on, As if it were suspended.

This is the normal way and 50℅ times my radio works in this way. And if we don't turn on the engine before 30 seconds radio Will shut down.
But 50℅ times after suspend mode it doesn't shutdown

[Q] Slow charge...

Heya,
I've been using my OPO for 2 months now and suddently it started charging slowly. I'm on stock (everything) with original cable. I've tried other cables as well (to power outlet & USB). Charging the phone whilst having it off doesn't seem to improve the speed of charging.
During the night, it charged 6%. Impressive stuff. Anyone with ideas?
Seems like its for sure a problem. You're sure that the cable isn't getting loose and is not charging right? Check about phone, does it say Charging (AC)?
Yes, it shows the charging symbol... I'ma shut it down for a couple of minutes and hope it heals itself. Plan B will be to put it in the fridge overnight.
You're using the original charger as well? Have you tried any other chargers that are 1.8 A?

Also if you can try your OnePlus charger and cable in another phone.
Why put it in the fridge?

Yes it's the original. I've tried 1.8A micro USB charger from my Blackberry and 2.0A from SGS5 as well with no result. But I got it working (explanation below).

The charger worked fine with my Blackberry and SGS5.
The fridge thing was just a joke
However, the solution was really unexpected. Everything was stock, so I decided to root it and try a custom rom/kernel. I switched to Mahdi and AK and then it started working again. 10% in 30 minutes. So I reverted to stock and everything is working now. Now I'm just puzzled to why this happened in the first place, and if it will happen again...

10% 30 minutes doesn't sound right, mine charges 35% in 30 minutes.
Your batterystats.bin file was most likely bugged.
Should you experience this problem again, delete it. It's located in /data/system/ or use the app battery calibration from the Play store.
Hm.. same problems now again.. 2% in 4 hours. Will delete batterystats.bin and hope for the best.
God damn it.
Yeah, it's a common bug on some OPO. Mine is quite good for charge but my friend's opo got a some problem and one of this is the slow recharge.
Do a full wipe and flash a new ROM or older 11S

Yes, sorry, 38R.
I'm thinking of installing a custom ROM - but I like stock a lot. But this battery bug is preventing me to keep the phone up to date.
I'm relative new to this phone and I don't know all the ROMs. Any advice would be appreciated.
Cheers

LiquidSmooth is best custom for the OPO.
Or try CM stock and not CM 11 OS (also called CM11S

Thanks a bunch man. Will try LiquidSmooth :good:
Install any ROM except the ones based on Omni.. (like the SlimROMs) and flash boeffla kernel. Keep the AC Charging Current up to 2200A. It says it may damage the USB Cable or charger but nothing ever happened to my Galaxy S3 (on the same kernel) or OPO. It charges extremely fast with the original USB cable and charger. Try it! Worked for all my friends!

This has nothing to do with the thread that you're posting in. Look at my guide:

i am having same issue.
rooted, runnning Sultanxda's cm12.1 . stock charger and cable, charging at around 500ma :crying:
any1 can help ?
I have bought the OPO 1 year back but started facing the slow charging problem since last couple of months. I think it has to do something with recent CM updates. When phone is on, it charges 3% in 45 mins but when we switch it off and keep for charging it charges 25% in just 30 mins. Strange.

[HELP!] Random shutdowns

So for the past week I've had the strange problem of N5 randomly shutting down, but ONLY when my screen is on. if I'm listening to music, I can listen until my battery runs out, but if I'm looking up stuff or playing a game, it'll shut down after a few minutes at varying lengths of time(It's a sudden shutdown so my screen just goes black when I'm in the middle of something).
After it has shut itself down and I try to turn it on then it'll turn off after the boot animation and before the lock screen shows. If I want it back on then I can get it start up again if I have it connected to a charger until the lockscreen shows and it'll act like normal(besides the whole random shutdowns)after I unplug it. I also don't have this problem when it's plugged in.
I've tried changing roms, kernels, and flashing the stock firmware with no success. I'm currently on XTraSmooth(Lollipop) with ElementalX 4.04 kernel.
Mmm dead battery?

Could be a problem with my battery, but if it was, would my phone also die when the screen is off and I'm listening to music for hours. Also when I plug it in just to turn it on then the battery percentage isn't low, tho it might drop a little.

Don´t start after screen change, but the screen works

Hello, i´m having this trouble. I chance the screen of a mi4c that was working fine. Then when i try to start it, i won start. i even use buttons combination and let the power button for more than 3 mins. the thing is, that when i conected to the power souce, it shows the mi logo and then the batery like it´s charging, but only shows 50 % baterry, it never change, does anyone have a clue? thanks

Maybe the screen you bought is not compatible. Someone had the same problem with the screen staying on the MI logo and apparently the screen wasn't compatible.

how can i tell if is compatible or not?
it is a common issue with replacement screens. I don't think you can do that much for it.
Try to find a original display part or giveup

My U12+ like a paper holder

This morning like all the morning I wake up and turn on the phone, nothing. No vibration, no charging led. Already tried to press all the possible combination of buttons
I can't tell if last night it was successfully in charge.
Yesterday I used it like normal without during something unusual, no update, no custom fw etc.
I contacted HTC UK, very bad support. At beginning they said to send it back and have full refund, now just repair. Pre ordered on 23 of may, arrived end of June, died beginning of August.
Any helps ?

This isn't the first U12+ nor the first U11 where such a thing happens. Didn't check regarding other devices, but checked with someone at HTC. According to my source there's still some weird bug in an Android core component leading to devices just hanging up, seemingly with no way to restore them to working order. They don't even show a charging light if that very thing happens. But after some time they wake up again, mostly at 0% charge as yours, and start working normally again.

That's why I never let my phones get to 0%.

It got to 0% cause it was hanging, and thus discharged. You won't be able to do anything against it as well.
