ROM Experience

Hi guys, on my quest to find a custom ROM that suits my need, I got to test a few and here are the results, hope it helps you to choose:

Notes:

- All these are tested on my device only, with my usage, and a "sort of" standardized condition so chances for variation, though still available, are minimum

- App of my apps (that might run in the background, all logged in) are :

+ Social: Facebook, Twitter, Instagram, Patreon, Reddit, Tumblr, XDA Lab, Messenger, Skype, Discord, Telegram

+ 4 banking apps

- Battery charge info are provided using Accu battery, temp info are from AIDA 64

- (XX/XX) stands for temperature with this format (CPU Temp/Battery temp)

- All the test are done with a freshly installed ROM, stock kernel, with one charge to full 100% before the test, and forced Cache* optimization has been done.

*For the Cache, please refer to https://forums.oneplus.com/threads/...-and-battery-calibration-myths-busted.993896/

Standardized test:

SOT: Use caffeine mode to keep the screen on infinitely, browsing Facebook/Twitter/Instagram randomly till it drops 5% of battery, calculate the time then multiply it up.

Drain: Play a match of PUBG, Leave phone in PUBG training mode

Idle drain, leave the phone for about 4hr of screen off, check result in Accubatery

(take this one with a pinch of salt)

Charge: normal charge and charge while in PUBG training mode (simulate charge while gaming)

Battery result samples (PUBG match):

- OOS 9.0.4 with Holy Dragon: 35m (73%->59% | -14%)

- iPhone XR: 35m (65%->54% | 11%)

ROM Results:

Syberia (20/06/2019): Est. 6h+ SOT

Drain:

- 30m (45%->29% | -16%) PUBG Match

- 17m (8%) (54/38) PUBG Training/4G

- 1.1%/h (Idle)

Charge: (56/42) (PUBG Training/4G)

- 54%/h (~1380mA) @>80%

- 40%/h (~800mA) @>90%

Experience:

- Quite smooth overall with many customizations

- Some lag and freeze here and there but not much, however, there is some sort of bug in the "Choose fullscreen app" option where the switch interferes with the scroll bar, so when you try to toggle, it moves the scroll bar instead.

- Good temperature while gaming (comparable to iPhone XR)

Omni (19/06/2019): Est 5h+ SOT

Drain:

- 30m (59%->41% | -18%) PUBG Match

- 15m (58%->52% | -6%) (50/37) PUBG Training/4G

- 1.7%/h (Idle)

Charge: 42/34 (no load/4G)

- 122.7%/h (~3350mA) @<60%

- 115%/h (~2750mA) @<75%

- 93%/h (~1780mA) @>75%

Charge: 52/42 (PUBG Training/4G)

- 115.6%/h (~3000mA) @<60%

- 103%/h (~2450mA) @<75%

Experience:

- As they said, rock solid, I have not seen any problem at all

- There are still customization but IMO not very easy to find (I have to use the search bar more on Omni to find what I need in term of customization)

- Ppls report that battery is good, and I did hope so until I got the result, I didn't test Treskmod (which also reported with great battery) but maybe it's the kernel thing? Idk, don't take my words for it.

Pixel Experience CAF (20/06/2019): Est 7h+ SOT

Drain:

- 32m (68%->52% | -10%) (good temp) PUBG Match

- 14m (61%->55% | -6%) (good temp) PUBG Match

- 15m (75%->70% | -5%) (50/36)

- 0.9%/h (Idle)

Charge:

- 127%/h (~3500mA) @<60%

- 117%/h (~2820mA) @<70%

- 99%/h (~1850mA) @>70%

Charge: (49/37) (PUBG Training/4G)

- (~1400mA) @>80%

Experience:

- Not much customization (or if there even any ;) ) so it's like OOS with Pixel skin (with no Oneplus gesture)

- As smooth as (if not better) than Siberia since I encouter less lag ot freeze, but there are still some so it's not as stable as Omni.

- Good temperature while gaming (comparable to iPhone XR)

- The battery is awesome IMO, took me by surprise.

Conclusion:

Not really a conclusion but I'm gonna keep Pixel Experience CAF to use for a while and see how it hold up. If any of you use Omni, what's your experience?
