OnePlus 3 has one huge major flaw in OxygenOS, and that is overly strict battery saving.
- Notifications are delayed because the phone is under Doze. You often get email notifications as soon as you unlock the phone, no notifications are received while sleeping. It seems that the only thing the phone responds under doze are phone calls and alarms (but only scheduled alarms, countdown timer doesn't work!). There is a big thread in OP's forums about this and it's a huge major issue.
- The countdown timer feature in the clock app is useless. If the phone dozes before the timer is up, it will not ring the alarm when the time is up until you unlock the phone. What the fuck?
- Pokemon Go is unplayable because the app loses location immediately if you switch to another app or turn off the screen. Yes, I want to go out on a walk with this battery murdering game, I have dash charging!
- Spotify Running does not work because it uses the gyroscope to detect how you run. Oneplus's stupid battery saver turns off the gyroscope when the screen turns off.
I know Oneplus is really concerned about battery life here, but this is going too far. They need to release dash charging ASAP because OxygenOS is crippled with this battery saving shit. I want to switch to Cyanogenmod or Paranoid Android now.
