[Android General] Celestial Fury:
* how to test *

Screen On needs to be

less than a minute

as we want to find out what's draining in idle mode. If you've used the phone then there's no way to tell what's acting up when it shouldn't be and there's no way to separate the active from idle.

In BBS Settings - Advanced

Untick Alarms using API & Kernel Wakelocks using API (it's less accurate) unless using API is the only way to show alarms & wakelocks for your phone.

STEPS

Establish Baseline (battery

ONLY

drain)

Charge battery to full (100%).

Switch phone OFF.

After 7 hours or so turn it on.

To get drain / hour, divide % of battery reduction with number of hours the phone was off. Example, if battery % dropped by 1% after 7 hours, then 1 / 7 = [0.1%/h]. This is your battery only drain, without drain from Android OS, radio signal, WiFi, data, wakelocks, & alarms. You can't get a better drain than this without removing your battery.

Establish Baseline (Airplane Mode)

Charge battery to full (100%).

Switch phone to Airplane Mode.

After 7 hours or so turn off Airplane Mode.

Check drain in BBS. This is your battery drain, without drain from radio signal, WiFi, and data. You can't get a better drain than your battery only baseline.

Test Idle Battery Drain

Charge battery to full (100%).

Reset Amplify

Device Stats

NOT Reset to defaults.

(Useful for troubleshooting which limited alarm/wakelock is causing trouble)

Leave phone idle for 7 hours or more.

Check phone for any unknown reboot (running time in Amplify & BBS must be the same. If BBS has a MUCH shorter time or if it shows "Boot" instead of "Unplugged" then there was a reboot as BBS doesn't keep stats after reboot).

Report here for the cause of reboot and do not limit it anymore.

It is easier to use BBS as a guide for battery drain. Increase time of limited alarm/wakelock and/or limit other alarms or wakelocks. Don't limit something that doesn't cause drain for you (unless it's ads/privacy).

Repeat Step 1.

Your PHONE can't get a better drain than the two baselines.

[LINK] Why charge to 100% instead of setting custom reference and measuring from there?

Sometimes battery levels have been observed getting stucked at lower levels and not draining at all despite being in used for over half an hour. That is level lost and voltage lost are sometimes not in sync.

Level lost [%]: Bat.: -2%(71% to 69%) [0.3%/h]

Voltage lost [mV]: (4066-4066) [0.0%/h]

Level lost but no voltage lost or vice versa is not logical.

How to find problems with limited alarms/wakelocks

If it's not in the guide, you'll have to test it yourself.

In Amplify, RESET Device Stats.

Use the app you have a problem with.

Check in Amplify what alarms/partial wakelocks were triggered.

OR Disable Amplify, reboot and see if your problem still occurs.

If you need help

(Don't start using phone first - I can tell from screen on time)

ATTACH a Text Dumpfile - in BBS, --> Share --> Text Dumpfile and ATTACH as an ATTACHMENT (not post) the textfile. (Don't attach screenshots if there's a dump available)

IF Alarms & Wakelocks are already low OR if you have severe drain, then attach idle BBS text dumpfile + attach

(as an attachment, NOT post):

WARNING

To be safe, turn OFF

your WiFI before using this battery trick. All your saved WiFi passwords can disappear with a hard forced shutdown/restart). WiFi passwords are supposed to be saved to Google (if you have backup enabled) but they're NOT restored by Google.

Use

WiFi Connection Manager

to save all your WiFi passwords onto the SD Card.

NO posting in multiple threads for help (unless you didn't get a reply after a few days or want a different opinion).
