Battery Use; Android OS?

Hi,
I have a big problem with my nexus one phone. The battery life of my phone is very bad (only 12 hours, with NO (app) USE! (only text messaging!))
I think the problem is that when I check "Battery Use", the "Android OS" is getting 70% (and more, up to 93%!) of my battery use...
What can I do? I've seen other topics with this problem, but there is always a special app that's the problem. I've reseted my phone several times, so no new apps installed, and I still have the problem...
But sometimes, "Android OS" isn't running in the Battery Use, only the "Android System"... But once Android OS has started, it climbs up to 70-80-90%... Help?
Thanks!

It's clearly some program you have installed, start killing stuff or removing stuff one by one to see what it is.
All else fails, factory reset and start over.

Thanks for your answer,
but I've tried all of this, I have already done a factory reset (already 2 times!), but the problem stayed... Are there any know problems with android 2.2.1 running on a nexus one? Could flashing another rom solve the problem?

[Q] Galaxy doesn't go in standby > draining battery

I got a problem: my battery is draining REALLY fast, like 20% every 2 hours.
When I check battery history (*#64... code) it says that: int other usage : time without standby/sleeping (dunno how it's in English > got a Dutch version (Wordt Uitgevoerd)) is at 100%.
Partial wakelock: Maps is also at near 100%
Gallery is not present.
I've tried rebooting, but this keeps happening...
What is causing this?
Firmware: 2.2 JPA

Loook in Setting of the phone...There have many options for On/Off forderground and backgraund process and aplications...
Regards

What kind of option am I looking for?

I tried a factory restore, and it still drains with hardly any apps installed (just Gem miner, Fruit slicer, Battery indicator). Battery history doesn't show ANY app being run. Just shows that 'Other Usage > Being run (wordt uitgevoerd)' keeps increasing when I turn it off.
Please help, this device is becoming useless to me...

Battery drain after Android 9 update

My phone got the update to Android 9 a little over a week ago, and since then it has been losing battery like crazy. For example, last night I left it unplugged as a test, and it lost 30-40% of battery within 6 hours (while I was sleeping). Before the update, a fully charged battery was able to last for two days, now it doesn't even manage one. The phone is often noticeably warm.
I restricted all "consuming apps" some days ago, that did not make any difference. I also tried 3rd-party apps to analyze the battery consumption, but did not find any way to figure out what consumes all the battery in the background / while the screen is off.
Using Google I found other people with the same problem, but I did not find a solution. What can I do?

I had a same kind of problem but it started a few days after a manual update flash. I had been experimenting with some root stuff (mostly magisk though so they should go away by uninstalling the modules) but could also not figure out the reason for the drain.
I also tried to reflash only system and vendor partitions, but ended with a bootloop, so I had to flash the whole firmware again. No problems after that.
I would try a factory reset if I were you.
You can also try GSam battery monitor (if you already haven't) to figure out what's happening with your phone while the screen is off and it should be sleeping.

I upgrade the XPZ yesterday to 4.41 Pie. Charge the mobile after upgrade to 100%.
The current situation looks like:
18hour active, 30 Min Display, a few calls... Whatsall, newsletter, Mail..... are running in the Background, LTE, EDGE and WiFi are always on, BT has a connection to my watch...
88% are still in the Accu. (Save mobil datatransfer is aktiv; additional the option is enabled to reduce power consumption for apps in background)

Bluetooth maybe on?
Did you try by not putting to Airplane (you can put to Silent or Don't disturb), to see if still Awake all time?

Yeah is still awake

Same shiet here, but on B504. The greenify helped a little.

Statistics from full load or since it was unplugged, dissappear.

Hello,
since a time ago that I use XDA BBS battery app to monitor battery consumption. I've been using gsam battery recently because it gives me some statistics since the last time the phone was full charged or since it was unplugged that BBS does not give, if the phone restarts. When the phone restarts, those statistics / options disappear.
I bought the application from play store to see if it has added it but seeing that it seems the same, I returned it. That option Is it hidden and can be activated?, or is it not an option will be added?
I know what if the phone does not restart, if there are the options to measure from the full load or since it was unplugged, but when i restart the mobile, these options with their statistics disappear ...
Can it be avoided?
Thanks for help, regards.
(I used it in a rooted OP 7 Pro)
