one more note regarding protecting my battered Pro 1x: I ordered one of these cases, took out the wallet insert quite easily, increased the cut out at the bottom for the charging access, and figured out that if I open my Pro 1x, I can insert the bottom, keyboard portion into the case quite snugly, and then i can slide the phone close and open securely. I just have to memorize the locations of the up, down and power buttons as they don't correspond exactly, but not difficult. Now I don't feel like i'm risking another disaster. Hope this can be of help to others.

It would be far easier to stay with lineage 21.0: That branch still gets patched with ASB fixes upstream, so all you'd have to do is fetch the source tree and make the build, which is piece of cake. Basically all you need is a Ubuntu virtual machine with enough storage and RAM. Because of the new QPR release scheme, staying with 22.1 is more complicated: Only the latest QPR (22.2 as of writing) is getting patched according to the ASB. 22.0 and 22.1 are not and I'm not sure if the available ASB patches for 22.2 could be directly applied to them. At least in the long run you'd probably have

I've uploaded an updated build of LineageOS 16.0 for good-old qx1000 (SD835 Pro1) to: https://findus.zwergenschaenke.net/~puma/linux.html#lineagepro1 The ROM dated '20250528' contains backported ASB fixes up to patchlevel "1 May 2025". No other changes since last post. Have fun.

It does not seem to be everyone that gets this bug, but the risk is clearly there.

nothing constructive to add but i just wanted to say thanks i use my pro1 as my daily driver with VZW and would've hated to have to go through downgrading to a version that doesn't have battery problems.

Sorry, running a little bit behind this week... 😉 Lineage-22.2-20250602-NIGHTLY-pro1x with May 5th security patch installed smoothly via OTA. MindTheGapps15, and root was maintained.

Not that I have anything constructive to add, but in LineageOS's defence: They are stuck forever with the Linux kernel version and drivers that shipped with the original Android 9 OS. As the divide between increasingly modern Lineage/Android userland and the base Linux OS amplifies, bugs like this become more and more likely, unfortunately.

Next step 22.1 and factory reset here, wasted enough time on useless 22.2 - I wonder if it is like AICP a nice project that was just made horrible by some crucial bugs.... 😣 (PS the factory reset, sets the band selection back to the default LTE/TDSCCDMA/CDMA/EvDo/GSM/WCDMA) ADD: And back to a more reasonable consumption 4% in roughly three hour Will try "LTE/CDMA/EvDO/GSM/WCDMA (PRL)" on 22.1 just for the fun of it..... And it is down 4% in another 3½ hours

Well, and this will probably be my last comment on this unless something changes-- I updated both my Pro1 x and Pro1 (in that order) today to the latest OTA updates. On both I downloaded the updates and performed the install and reboot. I also looked around on both to find some settings (the same on both). Otherwise, I just let them sit. Both started out at 85% battery (the max I allow them to charge). 7 Hours later, the pro1x was 73% and the Pro 1 was 75%. I'm going to declare pretty confidently that I don't have the battery drain problem.

Lineage-22.2-20250517-nightly-pro1-signed.zip on May 5 (2025) security patch, installed smoothly using OTA. I have still the issue with the battery drain: 10-15% per hour.

In theory I think yes, but in practise very hard without seeing the display. One option could be to copy the content of the entire user partition, but again some interaction with the phone might be needed. If you have allowed google to take backup, at the least some data is saved. And if you allowed google to stea...erhm STORE your pictures, they will be saved in the cloud too, maybe in poor resolution though. But start booting it to bootloader. If you see a menu, it is software 'only', so you would know that you are unlikely to need a new display.

Digging three years back in history, we had odd battery issues previously, that magically disappeared Back then 10% per day was good, and 30% per day was horrible. Interesting to compare with the numbers we get with even 22.1 not to mention 22.2

Totally agree, and I really only use it for testing the usability of LOS, and have it idle as a workphone, that does not ring each month anyway... So would easily overlook al kind of bugs myself, I just check that it installs smoothly, check if the keyboard works (and it has not really worked for me for quite a while) - and else keep it on stand by. So if I suddenly could not make or receive a call there could go half a year before I found out....On the other hand a drop in idle stand by was quickly spotted.....

Well, Yesterday 11pm, I reset my phone. Now, I´m back on LOS 22.1.😐

Oh I know it is good people doing their best - I'm just frustrated, sorry for whining. But as you keep the 16.0 alive, we can hope that you, or someone else with the suitable knowledge, can keep the 22.1 alive, if the 22.2 stay broken.... Let us see what the coming months or the 23.0 next year will bring. But as this is a bug not all seem to see, I guess the chance for it ever being fixed is slim. As with any bug the first step to a fix very often goes trough being able to reproduce it.

Note that the bug is on 22.2, but NOT on 22.1

Lineage-22.2-20250531-nightly-pro1-signed.zip on May 5 (2025) security patch, installed smoothly using OTA. I have still the issue with the battery drain: 10-15% per hour.

...I got it at default LTE/TDSCCDMA/CDMA/EvDo/GSM/WCDMA just tried to change to LTE/TDSCCDMA/GSM ADD I: ...The "LTE/TDSCCDMA/GSM" ate 50% in slightly short of eight hours while I slept - so still utterly useless. ADD II: Tried "LTE only" (after some recharging) And this seems even worse. 5% in half an hour!!! ADD III: Now trying "LTE/CDMA/EvDO/GSM/WCDMA (PRL)" , as suggested by @CornholioGSM Absolutely horrible 9% in an hour, if it improved anything compared to "LTE only" it was by a tiny tiny margin.

So I took my pro1 and pro x and switched Sim cards.. This confirmed that, in fact, my Pro 1 is unable to do calls anymore. There was no problem with either sim card in my Pro1x. So, it may be that my good battery performance on the Pro1 is due to the fact that it can't use a SIM. I sort of don't care enough to do anything about it as I do not ever use my Pro1 as a phone. (I rarely use my Pro1x as a phone and it works). This also suggests that, to the degree that it is a LOS 22 problem, it does NOT seem to be a problem with the Pro1x version of LOS 22. Round and round we go... 😉

I installed it yesterday. The battery life drop is outrageous. Unusable.

Well we could live with that... I got a bit better, but mine is currently a REALLY minimalistic setup, and was with zero screen interaction, so that was to be expected. But in the order of 1% / hour would be what I'm used to see WITH the sim mounted and online on e.g. 22.1.

@TeZtdeviceInteresting idea with the Aeroplane mode, I will try that overnight WITH the sim physically mounted. ADD: After 11 hours in Aeroplane mode it was down to 94%, so roughly 0.5% per hour. Certainly not impressive, but tolerable. Will recharge, and see what the day brings, but has not got my hopes up high..... ADD II: still bad out of Aeroplane mode

hmmm still no answer why i (and many others ) dont have problems with sim included 😞

Tomorrow I will test it for 12 hours and 85% battery, with just Wifi and BT. No GPS, no active SIM / network.

..Nice @hling, we got a very long thread mainly with DIY cases over here:

I don't know if I have a suggestion, but I suspect more information is needed. Is this a Pro1x that was formerly working ok and this just suddenly happened? Or did it do this when you got it. If the former, what kinds of things were you doing with the phone? Is it Stock Android or did you flash some other ROM? Anything you can tell people will help them decide if they know something you can try.

I was curious about the availability of the replacement LCDs (Elephone U Pro display) as I hadn't checked in quite a while. The result is a bit alarming. Aliexpress, which used to be a reliable source (the little shops would run out, but other little shops would pop up with it), now seems to be completely wiped out on these. In fact the only link that came out of searching that still worked was this: https://www.amazon.com/Jaytong-Replacement-Elephone-Pro-Assembly/dp/B0B6362SSK It is double to triple the price it used to be on Aliexpress, and the seller's ratings are not stellar,

EskeRahn, I quickly glanced at the post about screen replacement and saw that CornholioGSM is located in the EU. I'm in NYC. So probably not feasible. When I press the on button today there was a flash of the wall paper intact and then black again.

Thank you, EskeRahn for the link! Unfortunately, today, mere hours ago, my Pro1x showed jumpy lime green lights at the bottom of the screen, then the top started darkening. I pressed on the power button to shut it down. I was able to see the red left before it started to fade to black. I touched the middle of the 3 selection (from memory). When I got home I plugged in the power and a bright light flashed....then darkness. I don't know the extent of the problem and i have not backed up in a while. Unless by some miracle my 2nd Pro1x gets shipped to me I will have to comb the forum for

Update: From 85% to 20% in about 4,5 hours with about 30min. display time + Wifi + BT Next Test: Complete Flightmode without any connections (over night)
