with my 4.2.2 update my phone's battery is draining fast when using wifi 3g only i can last 3.30 hours.but i did a reset,
repair with sony pc companion i read this article http://talk.sonymobile.com/t5/FAQ/Battery-time-and-enhancement-features/m-p/347874#U347874
it says
When using your new Android phone it will take approximately up to a week or so before the phone settles in its battery usage and power management, depending on applications installed and the amount of content in your phone. It’s worth mentioning that this evaluation that the phone runs in the background at first period of use will happen again after master reset or reinstalling/repairing the phone software. So if you have just reset or reinstalled your phone, this power management evaluation process will run again. So it might at first seem like your phone is consuming more battery power than before the reset, but its normal.
so is that the case for draining fast compared to my 4.1.2?
please help
Try to calibrate your battery, there are apps in the Google Play Store that could help, some of them need root, others not.
I recently noticed after the latest update excessive battery drain as seen in screenshots posted below. I have tried a factory reset and then unlocked bootloader to root and added greenify to try help save my battery. Does anyone have any tips on what else to try?
Have you tried to figure out what the Miscellaneous drain is? At least on my tablet I don't have that category in battery usage.

Miscellaneous is android figuring out the rest of the battery stats, it's normal for new devices.

If by "new" you mean recently flashed/factory restored, then I'm not sure what to say. Even after flashing a recovery image I've never noticed that category. The only reason why I asked was because I assumed that was what you were referencing as being excessive.
If you were referencing the 24+ hour battery life graph shown in your screenshots, then that seems about right. Unfortunately the tablet has never been known to have stellar battery life unless it's on battery saver 24/7.

Seems about right?! He had 7min 2sec screen on time. If thats "about right" to you... you need to RMA your tablet.
Clearly whatever "Miscellaneous" is, is his issue.

Ok, so I noticed the very same thing when I got my Shield, I haven't rooted (I had on KitKat to restore some backups, then didn't do it again in Lollipop yet). I contacted Nvidia's service via livechat and got this answer. It did some considerable difference, although I still think it's draining a little too fast, but my old tablet had a pretty strong battery so I was just spoiled by it it seems >.<
So here it goes:
Nvidia Shield Callibration: (this takes a while)
You will have to calibrate the battery for just one time and observe the device battery backup for 2-3days to see the changes.
1: Drain your Shield tablet battery by using it normally until it turns off by itself.
2: Power-on your Shield tablet, if it wakes up and if you see some power left, follow step 1.
3: If Shield tablet is now drained to the point it can't wake up, set the device to charge for 7-8 hours.
The device should remain off when you set it for charging here.
4: Unplug the charger after 7-8hours, power on and wait for the battery charge to drop down to 90-95%.
5: Once the device battery drops down to 90-95%, plug in the charger and charge for one complete hour.
6: Unplug the charger once the device is fully charged.
7: Go to Shield settings > Shield power control > Apps> select optimize all option.
8: Go to Shield settings > Shield power control > system>
• Set the brightness to auto.
• Change the sleep option to 2 minutes of inactivity instead of default 10 minutes inactivity.
• Change the processor mode to either optimized or Battery savings.
• Check the WiFi optimization on.
Observe the device performance and report to us if you are still facing issue with the battery backup..
And then they gave me some tips for better battery life in general, I follow them (mostly) and my battery seems to hold on decently:
1: Always use the Shield tablet charger and not the computer USB ports or any other charger as the power specifications vary from the device to device.
2: In case if the charger is missing, use the back port of the desktop computer to charge the device instead of front port.
3: Always remember to exit the application instead of tapping the home button which will continue to run the application in the background.
4: Restart your Shield tablet at least once in a week. This will refresh the device making it work faster and efficient.
5: Connect the charger only when the battery comes down to 15% and unplug the charger only when it reaches 90% or above. This will reduce the number of charge cycles which will make battery last longer.
6: Use a third party app manager like Clean Master and free the memory at-least once a day to keep the device running faster.
To notice if the battery is fully/optimally charged when the device is off, look for the led indicator next to the charging port. It should be green, indicating it is fully/optimally charged
OTA update to 9.0 available a couple of days ago so I let it install. Since then, I've seen considerably quicker draining of the battery, with my usage of the phone being much the same as before. For example, when I went to sleep last night the battery was at 64%, and there were no apps running according to a swipe up from Home, but when I woke this morning, battery was down to 2%. I normally charge once a day, and previously the battery was hardly ever below 50% after 24 hours - I'm a pretty light user.
As an aside, with 9.0 there no longer appears to be possible under battery usage information in Settings to see the percentage of battery that has been used by the various apps and processes.

Ok here. 62% drop over night doing nothing suggests you have a rogue app in there. I'm assuming you have ok cellular coverage and nothing has changed there by coincidence. I would reboot and force close every app you have that's not essential overnight and try again. Swipe up from home and clearing those apps doesn't force close the apps. Greenify is an app that (in manual mode) will make it easy to select as many apps as you want and force close the lot of them. If that improves the situation you can then begin to work out which app(s) might be doing bad stuff whilst you sleep...
Battery on my P2 has significantly improved with Pie even if I didn't have any major problem with 8.1 either. Overnight drain 3-4%. After regular use after a full day I easily exceed 5h SOT. Everything stock with just Greenify in non root mode. I couldn't be happier, best Android release so far for me.

I've had my p2 installed with PIE for about 2 days now. I suggest giving it a week (which is what I'm doing) and then getting a full overview of how my battery is performing. Usually, after any major OS updates, being that apps are trying to utilize your resources and a new version of Android would try to allocate and learn your usage (in this case battery), you'd get a much better definitive idea of your overall performance.
I also think that since its now available, turn on Adaptive Battery mode. After a day of upgrading the OS, Adaptive battery at my 26 hr mark of upgrade said that one of my apps was taking in a lot of resources to be used in the background (ES File Explorer). I made AB to stop ES from taking battery resources.
So in conclusion, if it a week and then you'll be able to get a better overall understanding of whether your battery REALLY has gotten worse or better.
Hope this helps!
Interestingly, my battery was dropping really quickly too after the update to DP3, I switched off Adaptive Battery and it fixed the issue completely.
I tried it again with Android Pie and the issue resumed, so I turned it back off. Maybe try this too?

Exact same problem here after updating. Even tried a factory reset in case it was an updating issue. Same problem. My battery is currently at 43% 4 hours after a full charge. And I've barely used it. This is really poor.
No new apps installed.
My Oreo battery life was great. I'll try shutting off adaptive battery as suggested - but seems a real shame if one of the flagship battery saving features is doing the total opposite on Google's current flagship phone!
Doesn't seem to be a massively common issue so not sure if a likelihood of a patch either
Just a quick update - Google play services has now become the biggest drain on my battery, just as it was before I factory reset after the first install...
Anyone else had the same?

I had the same issue and did the same thing... until dp3 and my battery usage was terrible again even with adaptive battery turned off. I ended up turning it on again and after about a week my battery usage was back where it was before. So there doesn't seem to be a magic bullet here. FWIW app usage offered no insight as to what was causing the drain in the first place.

THIS.
I got like 8+ hours of SOT.... no mobile network though, all day wifi use only.
I have this issue. Dropped about 40% over night. I found that turning wifi off stopped the drain completely. I did not have this problem with Oreo at all so it's not the networks im connecting to. Weird thing is this did not happen when I first installed Pie. This started happening about 3 days into installing. Also, I put it in safe mode and saw the same drain with wifi on vs off.
Hi guys,
I seem to have fixed my terrible battery life!
The below might be worth a try if you're still suffering from it.
I noticed in GSAM that RCSphone was the front runner in battery drain so did a little research and found this site.
SOLUTION: Turn off app preview messages (settings / google / app preview messages). Apparently its only function is to allow Allo messages to be received without the app. To me, totally pointless as i don't know - nor have ever met - a single person who uses it.
I've gone from draining 8-10% an hour (screen off) to around 2.5%/hour and from 1hr 35 total SOT to 3hrs 39 minutes with 32% left (and an hour of that was Google maps navigating, so a proper work out for the phone).
Do give it a try and let me know if it works for you.
Although there's room for improvement (idle 2.5%/h seems high to me!) and it's ludicrous that I should have spent several hours finding a fix for this on 100% stock android, I'm very happy to have a usable battery life back again...
Adam.
UPDATE: Seems like in the night I lost 40% again. Idle drain climbed it's way up to 5.6% in the night. Still an improvement from where it was before, but not quite as good as it first appeared...

@Burkules I drop 0.4 - 0.7%/hr over night with Bluetooth off/Wifi on/strong cellular signal. Much the same as it was with Oreo. Not quite sure why's there's such a big range (almost 2x) but either way it's ok for me. Did you try the technique above?

Cheers for getting back on this.
I left it on safe mode the other night and it still drained absurdly fast, which suggests to me it's a google system drain rather than rogue app, but will try again with app preview now switched off. Likewise will try greenify again and report back.

Likewise maybe app preview set to off will help me even more. If I recall correctly rogue apps can cause some google system apps to wake up, but perhaps not in safe mode...

So, switched off adaptive battery again (i'd enabled it after my short-lived miracle recovery the other day) and now I'm down to 4%/hour. Which is better but still really high for idling! Cleared cache and data in Google play services for good measure too as it still comes up super high on the list of battery drainers.
Booting into safe mode now to check the drain without adaptive there and will report back...
UPDATE: Exactly the same drain in safe mode. This is a straight up google problem....

Haven't tried this - but if the battery drain is the same in safe mode (with only google/system apps running) I can't see how it will make a difference. Ill be in rehearsal for several hours today so will force close everything and will then be leaving my phone idling for a few hours anyway.
I signup up to the google play services beta yesterday, and google play services no longer appears as one of the top battery users... but the battery drain is the same and the numbers given in *all* battery apps (Gsam/accubattery/system) don't add up to anything close to the actual % drain. System battery displays 15% of usage (with 'full device usage' on show) when the battery is quite evidently at 48% from full charge. Total cluster****. So pissed off I updated.
Have you seen any improvement in yours with any of these workarounds?

Nothing to lose by trying. And as I said, Greenify makes it easy/quick to do. Force closing is almost as good as uninstalling those apps as the vast majority of installed apps won't restart or run in background until you use them for the first time again. In my experience, quiescent battery consumption (e.g. noticed over night):
Is vastly affected negatively by poor cellular signal strength. Marginal coverage can really drain the battery fast.
Gradually gets worse between reboots
Can be improved (once it degrades) if you force close all the apps you've installed, and swipe away the background apps just before you go to bed!
If quiescent consumption suddenly rises I can normally fix it by force closing all the apps (not being sure which was the one gone rogue/suddenly misbehaving)
At night I generally have excellent cellular coverage, good WiFi, and Bluetooth is off. NFC is always off
I don't enable sync on 2 of the 3 Gmail accounts I have configured
I disable notifications from any apps I don't actually need them from
Quiescent battery consumption is between, say, 0.4% and, 0.7%/hr at home, around 2 to 3%/hr when out and about which I put down to all background data being driven over 4G instead of Wifi, and variable cellular coverage
I've not noticed quiescent battery consumption change between Oreo and Pie, but this may be because I keep force closing apps at night and not giving adaptive battery (which I have on) a chance to have the same effect intelligently
Turning off app preview messages has made no practical different for me
I'm completely stock (stock launcher, not rooted, etc.)
If you can't fix it, at least a factory reset as the next experiment has the option to restore *most* of what was there before (so long as you have had the backup setting enabled). But because not everything is restored it's still a pain. And if that doesn't work it's another factory reset and test and then restore everything manually and gradually :-S. But I think you already tried that?

Thanks, just tried that as well and my battery has stayed resolutely at 68% on idle beside me for the last few hours, previously it had gone from 100% down to 69% in about 4 hours whilst similarly doing nothing.

Hi
I've got a brand new PH-1 and haven't yet had time to set it up properly, only started it up, let it update software and used for an hour or so before testing the idle battery drain.
I haven't installed any apps or changed any settings other than to disable the google app (to prevent it listening for or responding to "ok google"). I tried out the 360 camera, signed in to gmail and browsed a few websites, before charging back to full and restarting the phone before this test anyway.
But leaving it idle with the screen off and with phone network disabled (there's not even a SIM inserted), only wifi on with good signal, it lost 65% battery in under 22 hours. Screen on time was less than five minutes.
Is this a hardware issue I should RMA, or is it considered normal? If this is normal and there's no easy fix, I'll probably end up having to return the phone anyway for a refund, because if it can't even last a day and half in idle there's no way it would last a reasonable amount of time with normal usage.
Any ideas?
Thanks
Since there isn't a sim card installed, try going to airplane mode and then turning WIFI on.
I am getting about 1.2% drain with cell network and wifi enabled along with all my standard apps installed.
On a typical day with 1-2h SOT, I usually have 60-70% battery left at midnight. I'd try to reset the phone, and then testing again - occasionally a system update will end up doing something funny
I left it overnight with airplane mode on, so even wifi was off, and it's a little better but not by much. Screen on time was one minute.
With airplane mode on, screen off, no dodgy apps, the phone really shouldn't be doing anything to drain battery.
I'll try a full factory reset and see what happens.
Just to follow up, a full factory reset seems to have fixed the issue. Even after doing the same things I had done before (connected to wifi, updated, logged in to gmail, etc) the battery now drains at a much more sensible rate.
Very strange that a factory reset made a difference since it was new from the factory when I had the issue, but I guess something strange happened in the update like dsip suggested.
Thanks for the help!

That's ? percent normal behavior. Anytime you flash a ROM (new phone =new ROM) you need to wait a bare minimum of a charge cycle (more like three in my experience) before you get the slightest idea what your actual battery drain is going to look like. think of it like breaking in the engine on a new car.

Greetings, I have a problem with constant wakelocks on my MI11i phone since the day I bought it. Those wakelocks drain battery by 30% overnight, but also cause increased drain during the day in standby too since they instantly kick in as soon as the phone is locked, overall resulting in poor battery life. Even thou I am not an advanced user and has no need of it, I went so far that I completely factory reset the phone(this was the 2nd time), then reflashed new recovery and new official ROM to see will that sort the issue, then for a good measure I also rooted it with TWRP and Magisk. I tried underclocking the cpu to the lowest but it makes no difference while in standby since obviously that isn't the case. I tried using icebox but there were no processes that had SNS or RMNET in their names, so I just froze some analytics apps. Both wakelocks are gone as soon as I turn on the airplane mode or switch to wifi. Any app that can help me freeze those or edit something in kernel?
I found a rom that fixes the wakelock, listed here https://miuiflash.com/roms/miui-csx/alioth/miui-csx-v13-0-8-0-stable-alioth
But i couldn't find a way to contact the author for more info can i fix the kernel myself
