That could really be the reason of my phone being so slow since then. Okey, think I got it, firstly I back up everything, then with fastboot flash the 4.4.3 image, and finally restore everything from the cache.

Will I need to unlock the bootloader again? And will the recovery and the root remain after all the process? What about the back up, which app must I use?
[Nexus 5 General] lolcopter:
Backup with Titanium and flash the new .zip (linked above) in recovery not fastboot, and flash the latest SuperSU just to be safe (1.99r3). Unlocked bootloader and recovery should remain in tact

My apologies I don't know much of anything about fastboot, only going through TWRP/recovery
[Nexus 5 General] KarmacDesign:
Okey, I trust you :) Gonna try that out.

I still don't understand something, why will it wipe all my data if I am installing it with the recovery? Isn't it like installing the kernel?
[Nexus 5 General] lolcopter:
You manually do the wipe before flashing (data/cache/dalvik not media) for a clean flash

Basically to set a clean slate for the OS-wide upgrade. Many people have dirty flashed but restoring apps takes a negligible amount of time in the big picture so might as well start fresh since it's a full system upgrade and not minor ROM tweaks
[Nexus 5 General] bigbamboo5:
I did nothing and apart from one data dropoff (I had to flick into airplane mode and out) and terrible battery life, all seems fine. Is there anything I should do now it's updated to tidy things up? Ta!
[Nexus 5 General] NaterTots:
Follow the steps in this thread.

There is a way to use the factory image and fastboot without wiping your data.

My OTA (in south central FL) showed up in the past hour. Can't apply it with my tweaks. Just curious as to when it would arrive. Unless the n7 script for Wi-Fi fix using 4.4.3 and Franco kernel works on n5, I'll wait on him before flashing system.img.
[Nexus 5 General] KarmacDesign:
No need of wiping data at all then?
[Nexus 5 General] mremo:
I didn't need to. All I wiped was the cache + dalvik, although it took forever to wipe cache at first. I thought it was frozen but I left it alone for about 15 minutes and it went all smoothly.

2 of my friends and I (different providers) got the OTA today. We're in Montreal, Canada. Updated fine. My hopes were that it would fix my work email (exchange enterprise via air watch VPN). Still not working :(

Google services :" nlp collector wakelock "seems to draining my battery after 4.4.3 update.

Clean flash, factory reset, twrp and rooted. Thats all.

What I've tried but it dint solve

-disable location report

-disable location history

It doesnt happen during 4.4.2

Anyone have any idea?

EDIT:

Selecting location mode to "device only" seems to solve the battery drain.

Sounds like the new radio issue. Can anyone confirm this?

EDIT2:

Just found "NlpWakeLock and NlpCollectorWakeLock Discussion".

In fact, no fb, no sync of any kind. No location. Wifi and 3g are off,

till I need them. G+ updated after 4.4.3 upgrade, but I cannot see

if it does something at all. Not listed in running apps.

I found posts that claimed the phone needed few charges to settle.

When I come home, I'll recharge device and take a look at drain.

Drain is not massive, but I see it going faster than on 4.4.2.

Best regards.
[Nexus 5 General] fxdil:
There's no major visual changes with 4.4.3 being mostly bug fixes. They had updated the radio with this fix, with most users agreeing that they got better signal and coverage with it.

Chrome popping up

Anyone else having this bug where whenever i close an app by pressing quickly the back button if the app had two or more windows (for instance, whatsapp and the keyboard, or the dialer and the call history) chrome will briefly pop up and close. This only happens if chrome is present in the last used list, if you close it from there everything is normal.

Any help guys?

iT IS A BAAAAAAAAAAAAD Update don't do it

The android update to 4.4.3 has many problems:

-low battery life.

-Poor wireless (Unstable wireless) - you think you have a connection while there is no internet.

I prefer to keep 4.4.2 than having 4.4.3 i want to roll it back :(

What the hell is Google doing ???!!!
[Nexus 5 General] Quickfire:
My battery life seems to have gotten much worse after 4.4.3. I can't be sure of the battery life while in use, but idle life is much worse. In 8 hours it drops 12%, when before it was only a 3-4% drop. I don't see any wakelocks either.

Android 4.4.3 + Kernels

4.4.3 + ElementalX-N5-0.43 = Crashes

4.4.3 + franco.Kernel (r53) = OK
[Nexus 5 General] JDM9499:
So was mine. It was noticeably worse...but it is now significantly better after clear wiping cache and dalvik cache in TWRP (or if you have CWM). It really is a night/day difference. Try that and see if that helps you.
[Nexus 5 General] CPNowell:
That just about matches my experience also since the update... (totally stock unrooted)
[Nexus 5 General] fxdil:
I'm running ElementalX and I've not gotten a single crash. Maybe there was a step you missed while flashing the kernel for it to do so.

Probably flashed ElementalX directly over a previous version of Franco
[Nexus 5 General] FirstEver:
Maybe it dosn't like encrypted phone.

Yesterday I upgrade my 4.4.2 to 4.4.3 without erasing data. Then try franco and ElemntalX to unlock OC (@ 2.5GHz).

Everything is fine with franco karnel but I have some issue with ElementalX. First crash on logo screen, then on passcode, then randomly (HARD CRASH - black screen).
[Nexus 5 General] dwasifar:
Stock, rooted, with TWRP and Xposed Framework here. Last week I just installed the 4.4.3 radio to see how it performed, and it seemed fine, so I installed the whole OTA upgrade last night from the zip in the OTA thread.

This morning on my train ride to work I noticed I was not getting LTE. I've heard of other people having this problem too. As an experiment, since the 4.4.3 radio zip was still on my phone, I reflashed the radio and wiped cache and Dalvik. The phone got LTE as soon as it booted, and held onto it the whole rest of the ride, which it has never been able to do before.

Now I'm not sure what fixed it. It doesn't make sense that flashing the 4.4.3 radio over the 4.4.3 OTA would make any difference, but it seems to. Unless it was the cache/Dalvik wipe, or merely the reboot. I'll have to see if it stays fixed.

I don't notice any difference in battery life yet.
[Nexus 5 General] FirstEver:
Yes, I did :p

So what do you suggest?

Because ElementalX is faster than franco in 3D benchmarks.
[Nexus 5 General] fxdil:
You need to flash the factory/stock image first before you flash ElementalX if you're coming from Franco.

Why thermal throttling is too much aggressive on nexus 5 ..

Experienced some slow down ..

Due to this .. .

Is it only on stock rom or other AOSP roms also have this so called FEATURE
[Nexus 5 General] szucsgf:
It actually has to do with the kernel, not the ROM. Some kernels like ElementalX have raised the thermal throttle threshhold because on stock it is way too low, as you point out.

When I run stock kernel I erase the thermal-engine.conf file in /etc and reboot. This removes all thermal throttling. This may of course come with other risks, but I'd rather have no thermal throttling than the thermal throttle that is implemented in stock kernel.
[Nexus 5 General] bblzd:
Never noticed any slow downs except when gaming for 30+mins and even than it's only minor. I prefer having a cooler running phone with a battery that won't degrade as quickly from excessive heat, personally.

I don't see why you would disable it unless you're going for benchmark scores.
[Nexus 5 General] nomancoolboy:
ok thanks for the information...

i will try different kernels as soon as i do the bootloader unlock/root/installing recovery..

[Nexus 5 General] alen1901:
Guys you really need to make clean flash of 4.4.3 image. Or at least wipe cache and dakvik cache in either custom or stock recovery. Not a single problem yet here. Running custom ROM and kernel, same setup as on 4.4.2, battery, performance and signals are about the same like before. Only back button random app showing and closing is happening a lot often then on 4.4.2

Slide 8 "Use Case 1" is probably particularly useful.

Something is causing your CPU to keep waking up while your screen is off. It can be a headache to try to find what it is but it's worth it.

Besides a general degradation in signal quality/strengh, after the update I can't get LTE on my int. Nexus 5. It was fine before, and the iPhone 5s next to me get's a perfect 4/5 signal bars. However the N5 didnt get an LTE signal once. I can manually force LTE over *#*#4636#*#* but then it won't connect at all as well. Tried completely going back to stock, relocked, even tried 4.4.1 and 4.4.2 with old modems. No LTE for me.

[Nexus 5 General] KidWave:
Put me in the bad battery life boat.

First charge cycle after OTA was really bad. Android OS process was eating through it when idle.

- Did a Factory Reset -

Second charge cycle is a bit better, but it's draining at a faster rate. Good thing is Android OS process is gone, but overnight lost 10% instead of the usual 2-4%.

I'll see what happens over a couple more cycles, but I'm thinking I'll flash back to 4.4.2. I didn't have any bugs or complaints and the battery life was amazing. It was basically the perfect phone.

With this update, there isn't anything changed that makes the phone better on a day to day basis for my use, yet the battery life is way worse.

You've got excessive battery drain and you're blaming it on 4.4.3, even though hardly anyone else on 4.4.3 has that problem, and you have a perfectly good alternative explanation for it (broken sensors)?

Just upgraded my Nexus 5 since a couple of days and I also see a hit in battery life, despite the fact that I have for the first time installed Xposed and the donation module of Greenify, which should grant me some extra juice...

In my case it seems to be the Cell Standby, and might have to do with the fact that the Radio also got patched.

I guess for my low-network-strength workplace, the change was detrimental...

Any advice?
[Nexus 5 General] itasoulas:
about battery drain....both on my nexus 5 and 7 the battery loss when idle is 0,5 and 0,4% per hour respectively (stock rooted). I tested this overnight. Concerning play services, try this to make things better though I didn't bother to try myself since everything works fine http://www.reddit.com/r/Android/comments/1zxri4/google_play_services_battery_drain_the_real/

I also keep most of the google syncs disabled but this shouldn't make a huge difference if everything was on
[Nexus 5 General] Quickfire:
I've wiped dalvik cache and phone cache, my battery drain is still there. I'd say when idle it drains about 2% per hour, when it only used to be like 1% for 2 or 3 hours. No wakelocks either. I can't say for sure if Android OS is using more juice, but my Phone Idle process is using more than usual. I've now changed back to Dalvik runtime (I was using Dalvik on 4.4.2), let's see if battery life improves.

Those with increased battery ? drain in 4.4.3, have you tried to see if it's the new modem that your phones don't like? Particularly if the additional battery drain happens with screen off ??

http://xdaforums.com/google-nexus-5/development/modem-nexus-5-flashable-modems-efs-t2514095

I would try the modem that came with 4.4.2 (the one that ends with .23) to see if your battery life improves. You just flash the zip in recovery, no wipe.

And if your battery life is improved, you might as well try the other modems to see if there is one that works best for you.
[Nexus 5 General] kingston73:
This made me laugh. I've been using a custom 4.4.3 rom and I generally lose about 0.5% per hour idle and when using I have seen up to about 4% per hour loss. For my normal usage I get through a full day easily and I can if I want get through 2 days without charging.

I'm wondering if the people who are having battery problems have dirty flashed over 4.4.2 or maybe have chronic flash problems and just have a dirty phone that needs a cleaning or a fresh start?
[Nexus 5 General] asdf1nit:
Before the update i would get 10 to 12 hrs with 3-4 hrs screen on time, bluetooth all day for music and calls. now im lucky to get 8 hrs and i have to be careful with my sot, its more like 2 hrs more than that is pushing it or it dies before im off work. as for my sensors they went out in feb and i just havent replaced my phone till now but they never impacted battery life and im not saying they are now either, the point was ill be getting a new phone and see if the battery drain stays the same...
