In the last week or so I have picked up my phone three times and it has been dead.
The power button doesn't turn it on again.
I have to take the battery out and then restart it.
I'm running a rooted 2.35 JVT.
I have nothing untoward running ...

Could it be a dead battery?
otherwise, tried to wipe and (re)flash a rom?
The battery is fine, and the ROM has been there for well over a year with no problems.
Finding the root cause of battery drain...

There are a number of standard steps to run through to find the root cause of battery problems, assuming the drain is caused by the OS or apps and not actually due to a physically failing battery.
I have been tracking a few battery issues myself recently and this is what I have learned from doing some reading on XDA:
There are two free apps on the app market that are typically used to diagnose battery problems:
Better Battery Stats
CPU Spy
I would recommend installing both apps. The third place to look is in the battery details in the system settings...sorry I can't remember what they look like on Gingerbread because upgraded to Jelly Bean a couple months ago, though I do remember there was less information in the stock battery info on Gingerbread.
IF you are not, indeed dealing with a physically dead battery, then the root of your battery drain is most likely caused by a background process or app that is keeping the processor in a partially active state even though the screen is turned off and one would assume the phone should not be using any power.
Android OS will automatically change the running speed of the processor in the phone based on the demand of the system. If only a few background tasks are running and updating information the speed might be 200 or 400 Mhz. If the system is running full out servicing a graphic intensive game the processor will likely be running at the full 1000 MHz speed. The speed of the processor will directly effect the battery drain.
The expectation is that when we turn the display off (not power down, just put the phone to sleep) the processor should need fewer resources and slow down, tending towards a state known as "Deep Sleep". At this point the processor us using very minimal amounts of power. Any app or process that is active in the background will prevent the processor from getting to Deep Sleep. The CPU spy app will allow you to check how much time the phone runs at various speeds. Once you install it and run it, then reset the timers in the menu and turn your screen off for about 10 or 15 minutes. Then 'refresh' the timers. Normally, you should see most of the time accumulated in Deep Sleep. There are standard background tasks such as syncing with the cell tower, updating time, mail, checking alarms etc. That will engage the processor momentarily but they should be relatively short compared to the deep sleep time. In my case, an errand process was keeping my phone at 100Mhz constantly preventing deep sleep.
Once you know that something is keeping the phone awake in the background, you can use Better Battery Stats to narrow down which process or app it is the cause. This app allows you to track the individual processes that are consuming the most time and preventing 'wakelocks'. Wakelocks are essentially an app preventing the sleep state and are very well explained in this post: http://forum.xda-developers.com/showthread.php?t=1827676
The battery info in the system settings can also be used to give clues though again, I can't remember how much detail was included in Gingerbread..
If your problem only started happening recently, then it could be a new app that you installed recently, a feature or setting you changed recently or possibly a recent update to an app that was already installed. Try to think back at any recent events that could have triggered a change in the system.
Common problem apps I have read about are:
- Facebook - seems to be bad at using lots of background processor time. (Don't run this app but reading several posts shows its a processor hog)
- Google Apps that sync - Gmail, Chrome (syncs browser history, tabs etc.), Google location stats.
The wakelocks link goes into a great deal of detail and is hugely valuable in nailing your issue down.
Good Luck, let use know via a post if you find the root cause...
Sorry, maybe I wasn't clear about it being 'dead'.
The battery is 100% or thereabouts, no problems ever with the battery.
The phone looked as though it was turned off, but wouldn't turn on again with the power button.
I have to take the battery out and put it back again, then it starts on the button.
I've cleaned the contacts, and it still happened.

To me, it sounds more like a rogue process messing up power managing or response, but it's hard to tell what it could actually be.
For instance, you might come a cross a game that leaves your phone locked in max cpu frequency, draining the battery without explanation.
If it was me, I'd re-flash the rom from Odin, perhaps with an sd card wipe too.

I found myself customizing my new device as always from day one. I'm still running rootless with great satisfaction: one ui in superb in managing screen dimensions, good lock 2019 gives me the perk to optimize my multitasking, thanks to the community i run great gestures interface. I use no compromise: always on high performance mode, WQHD+, 4G+ always on, sync with 2 push emails 90% of the time it's on, lot of Bluetooth devices connected specially when I'm home (headphones, computer, amazon echo, bluetooth earbuds). I made a very light debloat with adhell that counts about 20 apps disabled (including all bixby services, which don't drain much battery tough).
I have about 180GB occupied out of 512, roughly 2.5/3 gb of ram always available and no heavy app optimization services enabled (just adaptive battery as far as I can tell). I normally DON'T close apps from multitasking. I make heavy usage of multiwindow specially from messaging apps trough notification bubbles. Always on display only when I'm home. You can see below my usage which may vary from day to day but consistently delivers incredible performances and very exciting battery results.
The device is an SM-N960F 8/512, so it's the exynos one.
In following posts I'm posting other days of battery I have record of in as much detail as I could get at the time.
Day 2
Day 3
Same Setup here.
My Exynos last 3 Days with 7Hrs Screen On, or 2 Days with 8-9Hrs Screen On.
Right ATM iam on :
76% Battery left.
Usage Time : 20Hrs and 46 Min.
Screen On : 2Hrs and 3 Min.
Mixed Usage between Wifi and 4G.
But just using Samsung Browser, Youtube and Whatsapp. No Games or whatever.
Maybe i can reach this Time 8 Hrs Screen On with 4 Days of usage. But i think, maximum is 3 Days with 7Hrs.
I dont fight for battery. Iam just a light user. And i did debloat and use routines (Android 9). No enerysaver. 1080P
Exynos here.
Exynos here too
4G/4G+ always active outdoors, WiFi at home
Screen brightness on manual, above 60% most of the time
1440p active, I refuse to downgrade the display to 1080p
Bluetooth on moderately, headphones & computer
Chrome as my browser
Social apps include Twitter & WhatsApp
"Disabled" a couple services through adb (pm uninstall) method ~ not including Bixby although I never use it.. ever
Always on display is set to "Tap To Show"
Consistently leave my house with 100% battery early hours 6-8am & return home with 30% (or higher) without fail
My charging method varies, I either fast charge it in the evening & got to bed with it on 100% and wake up with it on 97%+ or I wirelessly charge overnight and wake with it on 100% using the official Samsung convertible charger
Overall, I couldn't be happier with its battery life.

May I ask do you doing any restoration, or data transfer from Smart Switch, Samsung Cloud or Google backup?
Or you just set it as a fresh new device?
I NEVER fast charge because I really have no need with this battery performance. @maple_mak I never wiped the device since i bought it, I made a dirty flash via ota for upgrading to Pie/OneUi, then installed as zip all the betas until I upgraded to stable and had 3 security patches from that moment. At the time I tried to fresh install as many things as possible but of course my samsung account and google account synced many data. If you have problems with battery I suggest you to choose wisely the apps you use and monitor their battery usage carefully. You can use gsam for that. The idea is that you need the device to do as less things as possible both in background and foreground: any automated activity drains battery, use features only if you strictly need them.
if you really can't understand what your battery problem is, I suggest a fresh install of the OS and most important after that a good set up of the system without installing "garbage". With garbage I also mean things that are useful to you but drain battery and execute tasks continously
No idea how you manage that. I've already dropped 12% in 2 hours ? this is my first Samsung since the S7 Edge, I probably won't get another after this. Not a fan of OneUI and the countless preinstalled junk apps that I never use lol

You can essentially disable most pre-installed apps through adb

Oh I know. Just can't be bothered having to do it lol rather they weren't there to begin with. I mainly bought it for the stylus, but I rarely use it. I think a smaller device in the future will suit better

You're welcome! I hope you got a good deal - I'm under contract with samsung so I will switch for few bucks to the note 10 as it gets on the market, tough the idea of staying on this note 9 for a year more doesn't hurt me at all. Enjoy your new machine
Since last 2 Pie Updates..batterylife getting closer and closer to Oreo. A bit more optimazion and we are back on Oreo runtime.

Hi, Would you mind sharing the 20 or so apps that you disabled? I'm not getting anywhere near your battery usage, and it would be great to improve it.
Thanks

Yes! It's not all the story since the apps consumption is negligible if you don't really use them, for instance be careful to disable functions that use sensor like the ones in advanced features, try to use as less bluetooth perks with the s-pen, careful with location and try to stay below 80% brightness. Charge without fast charging and stay as much as you can between 15%-85% battery.
Here the apps/services i disabled:
"Bixby" voice wake-up
Apps edge
Bixby home
Bixby Service

Clipboard edge
CoolEUKor (it's a font... whatever)
Customization Service (be careful this can mess up some elements of the ui like multitasking. I use good lock apps and have no problems. You can always disable Customization Service from your samsung account manager even if you leave the app active on your device: https://www.samsung.com/us/account/customization-service/ )
Edge Screen

of course you can enable the ones you want if you use them
I also changed my dns to 1.1.1.1, don't know the impact of it in terms of battery
Black theme to everything you are comfortable with
Setting to auto the always on display or using the feature that doesn't allow the phone to turn on in pocket use the ambient light sensor and proximity sensor - this drains some battery
Try to block as many notifications from apps as you can
My suggestions could never end XD try navigate every menu and value every option. Shortcuts don't really matter but the things related to sensors or automation consume battery. Every little thing you can adjust to your real need make the difference
Thanks for the tips @Sprov
Did you uninstall them via adb or just put them to sleep?
DNS, you just using an app for that?
Thanks
I use adhell both for disable apps and change my dns. It's a bit tricky to setup fhe first time, there's an official guide, with some passages peculiar for the note 9. You can search for the thread here on xda. You need also to get a knox license from samsung, all of this requires about 30 minutes the first time. Main use of adhell is ad blocking at system level but it has a lot of features. If you're only interested in dns and disabling apps you can do it with adb with the latter, for the DNS there's an option in the Connection settings on the phone: in More Connection Settings tap on Private DNS and type 1dot1dot1dot1.cloudflare-dns.com
Adhell doesn't work anymore because samsung changed criteria to get KNOX license. From now on I will use package disabler pro OR ADB to disable system apps and services, for ADS blocking I changed the DNS from the "more connection settings", you can use the one from ADguard or get a customizable one from nextdns.com
Man, I can't believe you're getting such awesome battery life from the SM-N960F. I have the same device (512GB variant) and I barely get 3hours SOT. I think I could get more SOT if I really pushed for it but I don't use my phone as often as some. I just don't see why it should be down to less than 15% when I go to bed (11-12pm) after taking it off charge in the morning at around 8am!
I did a google drive app restore when I set up the device so maybe this is causing the battery drain? or is there a chance I have a faulty device? I am still within my 30 day return period with the seller so should I return it?
Forgot to attach screenshot.
