Lollipop 5.1 Upgrade - Post your experience - Nexus 5 Q&A, Help & Troubleshooting

Yesterday evening I successfully installed new factory image i.e. Lollipop 5.1 on my Nexus 5 D821.
Here I am mentioning my experience after using it for almost one day:
1. Overall device performance in regards of speed is same as it wan in 5.0.1
2. Some graphic changes are there with new icons.
3. New shortcuts introduced for WiFi and Bluetooth settings.
4. In camera application there is one black dot appearing in middle. I haven't tested it with any other camera application. (I will update later)
5. Battery performance is poor as of now I am using, even poorer than on previous ROM.
Does anyone want to comment or share there experience?

1. Battery Improvements, now i can usw my GWatch again, in 5.0.1 it drains the phone battery empty in about 4 Hours -.- now same percentages in phone and Watch.

it will be better if we keep the discussion in the existing 5.1 update thread..

So far the OS itself feels a lot better, but I left my phone over night, sync off WiFi on. Location off. Lost 30% in 7 hours. I had a wake lock the entire night. So my experience? After almost 48 hours of using this, its rubbish.

[Q] Which Kernel should I use to reduce battery drain? [CM 10.1]

Hey everyone!
I flashed CM 10.1 yesterday (cm_p500-userdebug-cm-10.1 from jenkins. androidarmv6.org/job/android/ and I'm amazed how smooth and perfect it is working (A huge 'Thank you!!' to the developer )
The problem is that my battery drain is awful. It took less than 8 hours today to completely discharge, though I hardly touched it.
I used Battery Calibration and also installed "WakeLock Detektor" to see where the problem is, and it stated that my phone isn't asleep 99% of the time though the display is turned off most of the time :crying:
The main reason is a kernel-related thing named "suspend_backoff" that keeps it awake.
I wanted to install a different kernel, but I got no clue which one... I actually planned on installing the recent DorimanX-Kernel, but then recognized that this is only available for the Galaxy SII
Can anyone recommend a Kernel that keeps my system running smooth but the battery drain at a minimum? I basically need my phone for Messaging (SMS, WhatsApp, E-Mail), Calendar and once in a while as navigation system. So no need for spectacular game performances or so.
Are there other Ways to improve my battery life on that phone (I've read all the general tips for improving battery life)? Maybe some OC things I can change manually?
I'm grateful for any help. Thanks!

I found SweetnSour's version 11 kernel quite good with cm10.1.
However, the ROM needs some help to get good battery life:
Install 2xBatterysaver. It will turn off data and WIFI when the screen is off (turn them on periodically to allow syncing). There are various apps like this one.
Control WIFI. Use Y5 battery saver or Whiz WIFI manager. Y5 is tiny and effective but crashes on cm10.2. Both check for favorite hotspots, leave WIFI on and turn it off when leaving the hotspot.
Thanks for your quick response!
Just tried to flash Sweetnsour's Kernel, but it won't work. I flashed this one --> versionFINAL-CFS.zip
Is that the correct one or rather one of those? -->" version11-CFS-TWRP.zip" or "version11-CFS.zip"
Edit: What actually are CFS respectively TWRP? Searched the forums but couldn't find an answer
[solved] or rather [solvished]
After days of trial and error, cutting and re-enabling all connections from WiFi to 3G and hibernating, un- and re-installing basically all of my apps and trying loads of other roms I didn't love as much as this in the least, I found the source for my phone being awake basically 100% of the time.
The changelog of the mod stated that there's still this WiFi-issue that keeps the phone awake.
Well, though I've tried before, It now works: switching off the WiFi connection finally gets my phone to sleep.
I think I'll just be running on my mobile data for the followin days or weeks until this bug has been fixed.
Btw: A little hint for the developer (I'm posting here, since I'm a noob and can't post in the developers forum): When switching the WiFi options to turn out WiFi whenever screen goes dark, it won't connect afterwards. I always needed to reboot my phone when I wanted WiFi to work again. (This bug also caused my mobile data not to work. It apparently thought WiFi was running, though it couldn't connect.)

Battery Drain, still after trying some fixes

Hello xda,
I have my Oneplus One more than one year now, and the geatest thing I alwasy notices was the much better Battery life.
I dont know what happened, but before 2 weeks my One needed much more battery when i did nothing with it:
Before 3 weeks: 10 hour in the night, with only 30 min screen on, the One used les than 3% battery.
Since 2 weeks: same 20 hour in the night,less than 30 min screen on, the One needs mor than 13% battery!
So before 1 week i completly wiped my device, flashed an new custom recovery and installed stock COS12.
I had not backed up any apps or settings or restored them, but changed everything new in COS, so that i did not copy any mistakes which i had from before.
The problem remained and i still had battery drain when the devices screen was off.
So i searched in the Web, and installed a battery watch app.
These are the fixes i tried:
-Disable double tap-to-wake
- Uninstall Google Play Services updates and install the new ones from Play Store
- Install an App called Wakelock-Fix, which activates and deactivates one google update service everytime after rebooting you phone.
- Using Privacy Guard and disabeling the wake up and stay active settings from Google Play Services.
After i tried this fixes the battery drain stayed as worse as it was before but instead of the Google Play Services in the Battery Usage only the Google Services showed up!!!
Sorry for my bad English, I am from Germany.
And sorry if there is already a thread or Solution in this forum, but i searched some hours in the Web and did not find anything.
Please ask if something is not clear.
Screenshots willl come later.
Here are some screenshots:
https://drive.google.com/open?id=0B...xHSEJWamFEWDBicTNMYm1QWkZSclRhS2JJVXk2elhVTTg
Look at the date of the pictures to see the development from Google Play Services battery drain to Google Services battery drain. Also i added some Pictures of SetCPU with the Tim in State because before 3 weeks i had more than 90% of the time only 300 MHz but today i have less than 80%.
And i added some Screenshots of each Tab in BetterBatteryStats.
Nothing looks unusual there. Your screenshots from BetterBatteryStats show that in an 11:50:29 period it is as follows:
Screen on = 00:32:57
Device awake = 00:42:04
Deep sleep = 11:08:24
This tells us that your device isn't being held awake when it shouln't be, it's only awake a little over nine minutes more than the screen on time which is actually pretty good. Are you comparing Lollipop to Lollipop or are you comparing Lollipop to KitKat? What I'm seeing here looks pretty normal to me for Lollipop.
The Screenshots were made all within 2 Weeks till now and always based on Lollipop 5.0.2
Is this really normal? Because when i first got the device with KitKat i only lost 2-3% over 10 hours in the night and before some weeks when i had been longer on Lollipop the battery usage suddenly went up.
And the Google Services are still using lots of battery or is this normal? Because I had only Google Play services using the Battery too much and now i have the Google Services instead.
Just saw on Twitter that COS12.1 with Android 5.1.1 will come out, maybe i will just wait for the Update.
But thank you so far.
:good:

So you are essentially comparing Lollipop to KitKat. Lollipop doesn't get as good battery life as KitKat had, so that's part of what you're experiencing. Google Play Services and Google Services are the same thing, it's just showing up differently in your battery stats page. Honestly, I don't think you have anything to worry about, everything in your screenshots looks completely normal to me. Just enjoy your device. Maybe try the latest COS12.1 update or a custom ROM.

Help with constant "system_server" high cpu usage

I am running 5.1.1 on my Nexus 5, and have recently noticed reduced battery life. When running Quick System Info PRO, I notice that "system_server - BluetoothPhoneService" is constantly consuming anywhere from 15-60% cpu, usually 20-30%. I have tried everything INCLUDING restoring all the original factory ROM's, starting with 5.0 (LRX21O) up to 5.1.1 (LMY48I), yet the issue persists. Toggling Bluetooth doesn't help any. Bluetooth functions normally when needed, but is usually kept off.
Has anybody else encountered this issue?
Any advice would be most appreciated.
Thanks,
Mike.
same problem
Hi, I've the same problem since the last Android update! Quick system info shows that system_server (BluetoothPhoneServer) uses ~24% CPU and >82MB memory. The device gets warm and batterie is empty after 3-4 hours.
Hello,
I'm having the same issue but with another phone (I'm off-forum but not of topic).
I recently made a factory reset to try to solve a problem and now the battery drains quicker than before.
According to Quick System Info Pro, the process system_server BluetoothPhoneService regularly takes at least 15% CPU.
I'm running Lollipop v5.1 stock room on a Wiko Highway Star
If somebody had an idea...
Thanks

Few Sony Xz problems [ need help]

Hello, members!
I updated my sony about month ago to new android version Oreo (Android 8.0) and at first i was happy that Sony made an update, but when i started to work more with this version day to day i found that there are things that i dont like!
First thing with apps and folders
Apps like Facebook and Massenger all the time show @ app that i have notification (number on the app) and when i open it there is not any notification for me! Apps all the time showing me the same number of notifications on app but there is nothing in it.
Started to search it, maybe somewhere it is - but there is nothing! I deleted apps and install it again - but it show me all the time the same!
I am tired with this thing - i know it is small problem but in my day to day work it is seriously.
Second thing - Guys what we can do with high phone temperature ? Phone is overheating sometimes when i using it and i am not playing games! It getting uncomfortable hot!
Third thing - When phone getting low energy (about 30%) it is automaticly turn on battery saver! Of course phone start to go slow. In setting i can turn off battery saver but it still are slow because i am more than sure that battery saver is still on, but in settings it is off! when i plug charger to phone it starts to work Great!
Can we do something with these things?
P.s. I think it is to many problems for Sony mobile - i was using a lot of Sony phones but about now starting to think change Sony to something else...better!
Hi, I have updated to Oreo as well. Not experiencing the overheating issue. I upgraded to this handset from Galaxy S4 i9507 and that one used to get hot. Maybe try disabling some apps after checking what is using the battery. Maybe you have a sneaky app which is using a lot of CPU.
Generally, this version (second version of Oreo) is a bit slower than Nougat, particularly camera operation. I am seriously considering rooting if I can be sure that DRM and camera will be preserved.
Try factory resetting the device, that tends to solve most of the issues after a big update. Also if your Play services version is 11.7.46 make sure to update to 11.9.51 via apkmirror as the former is confirmed to drain battery.

1. I don't suffer from this issue perhaps try updating your Xperia home launcher
2. The phone does heat up from time to time , all electronics follow the same principle
Electronics will heat up
3. Stamina mode is actually disabled just as it says on the settings, the reason the phone is slow because there is not enough power to be supplied as the demand for performance increases
When power is low your phone struggles to deliver optimal power to performance ratio
To make sure that the phone able to last throughout the day so that you don't miss any calls ,
Performance is decreased in favor for battery runtime

Battery life considerably worse after update to 9.0

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?

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.
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.
