Hi,
The old one was 1.1 and the new is 1.1, but different number - the new one is 1737 the old one is 1728
The uptime is 145hours without any restarts.

This is a photo of the old one https://www.dropbox.com/s/avsu7tn6my1i070/2018-01-11%2021.15.28.jpg?dl=0
The photo of the new one can be seen on https://www.dropbox.com/s/srqp4mdglgit7b5/Screenshot%202018-01-11%2021.21.50.png?dl=0

Best regards

Thank you for the detailed feedback

Hi ibenkov,
Can You confirm,that battery drain has gone?

Absolutely!
4 days with one charge!
before was a real nightmare - it was not possible to have a day on a battery. Now the cpu is sleeping, not as before.

After the OTA update v0.1_20170803_20180105-1104 my phone does not reboot itself. I did the factory reset. The charging board is the original.
Remaining bugs:
Quick battery drain and slow charge.
Crackling sound when media start (mp4-format).
I hope the next update will fix these bugs.

4 days with one charge, can you be more specific?

- how many SIM cards are in?
- SD card installed?
- is data transfer constantly on, is LTE enabled?
- are internet demanding background tasks such as synchronizing enabled?
- how many minutes are talking on the phone daily?
- daily screen on time, average?
- screen light setting?
- cpu-z screenshot would be nice

Cheers,
Chris

Hi Chris_2017

2 sims in
SD Card installed
LTE enabled - mobile data always in use
Google sync enabled

for the other questions - will answer later and post screenshot because the phone is a gift to my father and He is using it.

Best regards,
Ivan

Guys, let's keep this thread on topic. We are talking about reboots.

Refer to this thread for the battery drain problem:

Anothe update on 20171219 firmware, my phone still doing nothing, but it doesn't restart from 258 hours. I know that when you are using phone it maybe different, but before this firmware update it never gets to 3 days without restart.

I found nearly exactly the same result.

Before this specific update? 2/3 reboots a day, guaranteed.

After this update? No random reboots for 200 hours plus, then 1 reboot after about 244 hours... Then no reboots again. At 154 hours currently.

Are we absolutely CERTAIN that this is a hardware problem, and not a software problem? Because quite honestly, if it was a hardware problem I would expect a software update to make little/no difference on reboot frequency and this update (i've not tried latest because honestly I don't want to make anything worse!) has restored the phones functionality well.

A software update can mitigate the hardware problem A LOT but not fixing it at 100%, as you can clearly see from your feedback.
Reboots are mitigated a lot, but not solved at 100%!
