My tablet reboot when 15% battery using chrome, will test me see if its constant b problem

I am tempted to go back to 15.1. This ROM is otherwise excellent, battery drain is its only issue, but it's a huge one. Yesterday I lost 17% of battery (100% to 83%) in about 20 minutes of light browsing (no videos or animations, I was reading an on-line newspaper) with the display luminosity set at somewhere between 50% and 60%. The tablet was getting warm as if I were gaming.

This morning - I just checked - I see 2% idle drain and the CPU never goes into deep sleep.

What kind of battery drain were you getting on 15.1?

The idle battery drain depended inexplicably on the build. That said with a good build it was hovering at maybe 0.7 - 1%. Thus not really good, but still much better than what I experience with 16.

When in use the battery drsin depends clearly on what I am doing, so it's difficult to draw conclusions. However in a few cases I noticed a clearly excessive battery drain with LOS 16. I haven't installed new apps for ages (I use my tablet mainly to read ebooks, watch Netflix and browse news sites) thus I don't think that a badly written app might be the culprit.

I agree that the 15.1 builds varied significantly on battery drain. I have had a better experience than you with a "good" build. I am currently running the 2/20 build and it's very good. I turn off wifi and close all apps and lose only 1-2% in 8 or 9 hours overnight. AccuBattery reports .3%/hour over the last 70 hours, which is about a week because I usually turn it off at night. I'm tempted to try 16 but will hold off for now. I don't want to have to do a factory reset if I decide to go back to 15.1.

I never turn off wifi. However also considering that, the drain of LOS 15.1 was still a bit high even with a good build. Based on my experience, if battery life is important to you, I would wait before upgrading. Otherwise LOS 16 is very smooth and stable, a very good ROM.

It would be interesting to see what the overnight drain would be on 16 with wifi off. I will leave wifi on tonight and see what happens.

I wonder how the age/condition of battery affects drain? My S2 is just over 2 years old and AccuBattery rates the health at 91%.

For what it's worth, on LoS 15.1 (but not the 2/20 build) and 16.0, I was getting 0.6%-0.7% per hour idle drain, no matter what I did with wifi or anything else. On the stock UK build from 2/20/19, my battery drain is something like a 2-3 percent per 24 hours with wifi off. Same device, so battery age isn't an issue in my case.

Overnight with wifi on but all apps closed, battery drain was 7% in 9.5 hours ( from 67 to 60). That's about .7%/hour, quite a bit better than people are getting with 16. Still quite a bit higher than the drain with wifi off.

Running pie. So used fing to check on my network/lan & see listed with an ipaddr, AirGo, as a device connected to my network! What is device "airgo" doing?
A search says that 'airgo' is an app, usually. Found that 'airgo' only applies to Oreo & Pie, so far.

Any problems if I disable or delete 'airgo'? & the USA govt claims that Huawei is a security risk when facebook is more so. then Qualcomm sneaks a device onto my network from my tablet. Interesting that both S2 & Nexus 7 have airgo with the same ipaddr. A google spyware?

For those who have flashed multiple 16.0 nightlies, have you found that battery drain varies widely from build to build as it does on 15.1?

Before the March 12 build the idle drain was just awful. However the last two builds are quite good. The CPU finally goes into deep sleep and the idle drain is massively lower, at about 0.6 - 0.7% per hour. Let's hope that it stays like this!

A big thank you to the developers!:good:

Strange. I don't see anything has changed since March 12.

I can assure you that suddenly the idle battery drain dropped massively. On previous builds the CPU never went to sleep. Now it does for most of the screen-off time, which certainly explains the much lower battery drain. Other than flashing a new build, I didn't change anything.

I haven't looked at the changes between the builds but now I'm curious.

I didn't see anything obvious either, but yesterday's build was significant better (1% loss/hour) than before. There were some "POWER"-related commits, but I don't know what they did.

This is exactly what I got with the early February 15.1 and 16.0 builds. It equates to about 14% drain every day. Stock drains maybe 5% per day, so we're talking 5-6 days of idle battery on Lineage vs 3 weeks on stock. I feel like there's a very long way to go.

Things are marginally better at best. I lost 16% over 12.75 hours today with WiFi turned off and *zero* access to the tablet. Logs were provided, but the developer who was berating us for lack of logcats hasn't responded since.

Wait, since when am I a developer?
All I was saying is that if the developer can't reproduce the issue, they will need logs

I flashed the 3/13 build yesterday. I left it on last night, wifi off and no apps open. Battery drained from 66% to 63% in 12 hours. That's about the same as I got under 15.1. It may be worse than stock but I can live with that.

Hi all,

I just wanted to chip in and say that I was running and early 16 build and was getting the same battery drain, dirty flashed to 20190314 nightly, now accubatttery is telling me I'm getting 0.4%/hr battery discharge for screen off time (for 16hrs of screen off/deep sleep). Awesome!

This is my first experience with lineage. I really like this little tablet, and being able to run Pie is, well, delicious!!

Thanks LuK1337!

Maybe it's placebo or something I saw a flat curve sleeping after updating to the latest build lasttnight
