[Nokia 7 Plus Guides, News, & Discussion] nexus723:
Hey guys! Posted this on Reddit, and many people loved my guide and explanations, SO Posting this here and hope this helps everyone with issues about the battery etc.

After a few days of testing these are my tips to you guys, AND my experience how I got atleast better battery life to some extinct.

Now to the basic charging tip as some, and some not know. Charging between 30% to 80/90% is smart. Wears the battery much less than 0 to 100% for instance. Read this up further if you need, not gonna talk about this forever.

To the Nokia battery part. So first of all MANY users have reported Adaptive battery and auto-brightness are bugged and drains more than they should. Well this is true. DO NOT use adaptive battery if you experience bad battery life, and especially not auto-brightness. Why am I saying do not use it? Simple. It does the opposite, so is reported many others. I tested this carefully when sleeping to test the idle drain just by having the Android system installed and a few apps. I got a drain of around 10 to 13% through only 9 hours of sleeping. This is bad. However when adaptive battery turned off, no apps restricted I tested for many days and ended up with only a drain of 2 to 4% through those 9 hours. Will it help you? I dunno, but worked for many.

EVENWELL APPS. Usually bloatware. Only few apps from evenwell is needed for the OS to work. The powersaving g3 package from evenwell, which is a third party that Nokia has done some kind of deal with. The powersaving was suppose to help, but instead made things worse. Making alarms useless etc etc that has been mentioned on the forum. It kills apps even wehn whitelisted or when the phone was locked for a while.

Hook up the nokia on your pc and use adb. Uninstall this package, and almost all evenwell packages installed. Atleast powersaving g3 package, as it's known to drain. Most are bloatware, however you need to be careful not to delete the wrong packages, as they can only be restored by factory reset. Which packages to uninstall depends on your needs. Please remember to check on xda to find a guide on this, if not I will find it for you. This can help a lot just by using some of your time to remove stuff you might not need.

Turn off the aggressive 4g switch in developer settings. It will set 4g to always active, and you are better off just having it off. Should be called something like "Mobile data always active".

You got facebook? Well many has reported that facebook drains a lot, as it uses many services to communicate with the phone. I usually just use dolphin browser and have facebook logged in

Now for me I have these settings mentioned above, and I use my phone a lot, I get around 2 to 2,5 days of use of the phone just by doing these things. Uninstalling many evenwell packages helped a lot too. If none of these tips help you, then deleting caches can help. If not backup and factory reset the phone. If that does not work too, then it could just be the Pie updates being drainy for you. Hope this helps anyone :D! Ask me if any questions!

Question: When turning off adaptive battery it keeps turning on after a while. Answer: have atleast 1 app restricted and adaptive battery on. From there turn it off and let the 1 app stay restricted (it really isn't). Now it should hopefully stay off.
