'How To Get Better Battery Life' tips and tricks

I haven't seen one of these threads yet, and I think it will benefit users of our D4 forum.
If you have any tips/tricks, feel free to add them here.
My first tip: TURN OFF 4G AT ANY TIME POSSIBLE. 4g is a battery vacuum.

Here's the biggest....Widgets and Social Networks.
Watch your widgets (weather, news, facebook, etc..) that update/refresh. Most will allow you to adjust the refresh time. Set it high or to manual refresh.
Social Networks.....set them to refresh only. You don't need them refreshing their data in the background, just have them pull the latest down when you are actually using them (Facebook, Twitter, Google +, etc..). Set to manual refresh so that they only refresh when you are using the app. You don't need the latest status messages your friends are posting hitting your phone when it's in your pocket.
WiFi and. 3G/4G.....if you are in a location that makes your phone drop/search for signal and WiFi is available....use WiFi. The constant searching/seeking and establishing a 3G/4G network connection will kill your battery faster than having a constant 4G connection. This leaves the cellular band free for calls and all your apps that sync/pull data from the internet can happily run over the WiFi connection instead of killing your battery.

I second this, keep your widgest, number of home screens, and social networking apps down. Phones haven't reached the point of being able to be computers quite yet. Here are some apps to keep it snappy though:
Fast Reboot (by Great Bytes Software)- same as a battery pull without having to. Clears up a lot of RAM.
Lte On/Off - with this, you can switch to 3G (CDMA) only, and have it set to automatically default to that setting in the case of you switching to airplane mode for some reason. But it does reset the app if you turn of your phone. Fast Reboot doesn't clash with this app.
App Cache Cleaner - clears out a lot of the cache you otherwise would have to go to Manage Applications to clean out.
That's all I can think of at the moment for non-rooted users. I won't go into rooted b/c this is not the right place. But here are a few battery saving settings:
GPS - have only the Google one on, it's the fastest in my experience.
Display - have it set to the lowest setting when at all possible. Only lowers color distortion in my experience.
Developer optionss - go in here and turn on the force GPU settings. This may not be the case with everyone, but it gives my phone a little more zip and makes things smoother.
Apps (this is the very bottom of the developer settings) - Adjust these to your liking. Perhaps try setting the max number of backgrounded processes to 4.

I wonder how it looks on you ...
on my droid 4 and with Jelly Bean i lost ~5,5% battery by hour no matter what i do even on airplane mode.. still aroud 5% by 1h
please can you advice how its look from your side ?

I had the same thing with my Droid 4. I finally sbf'd it, and reinstalled everything one at a time. This fixed it.

i try SBF many time, formats, pull out sd card no matter what i do.. still lost 5,5 % battery by hour.. so max my battery keep 16-18h
(its there any possibility to move back to ICS ? )

Is there any way for the Droid to use only 2G networks? 3G/4G while idle seems to be the biggest battery drainer.

you just turn off your network data and you will still be able to run 2g

a battery calibration after rooting device should help.. what it does is delete the fake information from the old/stock ROM and cleans up your battery to new life... better explained here... https://play.google.com/store/apps/details?id=com.nema.batterycalibration...

I have not found that to be the case at all. The battery tools make that claim but it has not helped my battery life (stock or rooted) on any of my multiple droid 4 or d2g

Same here. In a couple cases its just made it worse. I will be trying out the extended battery in a couple weeks though. Hopefully it'll let me go at least a day without charging.

Making it better
The Droid 4 firmware just isn't very battery friendly... and it's not a new phone so your battery probably isn't either. Two things to consider.
LiIon batteries lose capacity over both cycles (cycling losses) and time (calendar losses.) If your battery is 18 months old and was charged nightly, you've lost 25% or more of the life anyhow... much more if the phone was kept plugged in after the charge and ran warm. And the drop accelerates with more cycles. It may be time to change the battery.
Adding JuiceDefender ( I use Ultimate) triples my battery life even in basic mode.
Replacing the battery is really simple; buy one from Amazon, open the back, carefully pry out the old one (it's held down by a double-sided tape), unscrew the connector (very small Torx, but jewelers screwdrivers work), swap and reassemble. $30 later (and a few hours to charge), you have your capacity back.

yeah after trying juice defender for about a month or so i noticed my phones battery life extend much more. so i opted to buy the ultimate juice defender and sure enuff more battery life... i am very pleased with this app. however if in the future i do want to extend the battery a lil more, then i will purchase a brand new battery and then replace the old one...

Turning off auto sync, turning off WiFi while on 4G works. Also make sure there's not any apps running in the background. Being root, there's apps you can download to close any open app

with CM it is an easy to safe much energy! and if you really want to do this on a right way, you really need to own a rooted system....
1. underclocked my cpu for 200mhz, dont have to comment.... if you use lightweight lounchers and care for background apps, it will noprob
2. use only 2g-networks, those are more available than every other networks, and even tcp/ip works with it, for whatsapp etc it is way enough bandwitch
very important!!!!
3. check your internal recievers after installing an app!! with "autorun manager" on a rooted device you can uncheck every function from every app, even autostart of an already killed facebook app, or statistical functions from apps which comes with most of them
4. get your brightness automated, if it is dark, you can automatically safe energy by a automatically regulation
5. maybe you would prefer to deactivate vibrations/haptic feedback/call vibration completely, its very energy consumpting.....
6. deactivate the gps-reciever complete, and just turn it on if you need it
7. set your display timeout as less than possible for your behaviour, 15 seconds may be enough
8. know what runs in background, evrything in background, sucks energy.....
9. deactivate nfc
10. deactivate bluetooth
with this i get a standby about ~1-3 days! and if im phoning and writing to much maybe not fully to one day. if i watch now on my energy tables, my display is consumpting still 40-60% battery per charge, but i dont think that even more safings would be possible
and with the app "tasker" you can even script this in endless environments

How does JuiceDefender save the battery? I have used many battery saver apps (including Juicedefender) and I always find that they run in the background and kill the apps which I would close anyway. Does it do anything besides kill background apps? By now I've deleted most background apps and have only kept the apps I want (which are few) and I still find battery life subpar.
Also definitely keeping 3G/4G off is a huge help. Wouldn't be able to make it very far without turning those off

I use Autorun Manager pro to freeze Google Play Services. Funnily enough, Play Store and Google Maps still work like a charm yet Google Play Services don't run background
Edited: With stock rom, install SetCPU and change the governor to hotplug. Underclock max frequency down to 800 MHz. You won't notice much different for normal tasks like watching videos, sms,...That setting is enough for me to play FF4 on MyBoy but playing heavy graphic games might not be snappy tho.

For me not using gaaps improve battery life. Every one knows for google play service that you cannot stop Instead I use calldav for my contacts.

me battery drain in me droid 4 jb 4.1.2 with gsm patch is of 60% for screen, the battery only run about 6hs, can i fix this? thanks

Google services is killing my battery on HTC one

According to gsam Google service Is the culprit if ny high awake times (see screenshot below). But how can I reduce this problem without defeating the purpose of having a smartphone,and according to the battery graph u don't see Google services listed at all.

/facepalm
A 21-minute wakelock out of a 12 hour recording session. The sky must be falling.
Unless you shut down any Google app using Google Play Services, no, there's nothing to do. The only reason it comes up as a larger power use is because it's essentially aggregating the power previously used by six or seven different apps. You seriously need to get some perspective on what constitutes "bad" battery life because you just keep posting "my battery suxorz" threads with less and less justification each time.

Hmm. I get pretty crappy battery life, but that battery life doesn't look too good. How much screen time? Your kernel should use about 25% of your battery. If you're on stock, that is.
Try clearing cache for GP services. Try using the phone for a day. See if that works. If not, then clear data.

Here is my current stats also I'm completely stock (no root) and my herbal US currently 23%,how much higher(percentage wise) can it get before it will start causing orovkens?

For stock non rooted,that seems about right. That's what I get. Around 13 hours a day with 3 how screen time.
Actually, you are getting much better battery life than I do.
What are your settings? WiFi? LTE? Battery saving apps? Facebook? I can't for the life if me get decent battery life. As I said, the kernel uses up 25% of my battery.
EDIT: Also, I looked at my stats, and it seems that Google services wakes my device a lot too. So yeah, your stats are normal. :good:

Is this normal for me? I left my phone overnight and it goes to deep sleep with barely no screen time but there's major drain. What is the difference between screen on time and awake? Is it some background services running? I checked the wakelocks and nothing seems wrong.
Edit: Looks like something is keeping the kernel awake. Does anyone know what is msm_hsic_host?

I only use the power saver with cpu,and data connection enabled,auto sync disabled,I'm on wifi when at home,and 3g/lte enabled when im away from home all the time,auto-sync disabled (no need for it). NFC and all location services are on all the time (google's location service along with GPS),brightness set from 0%-20% (depending on lighting conditions). I also use the facebook app with syncing disabled.If you have any other questions or if I missed something feel free to ask.

it ranges from 20%-25%,once it got up to 28% but I was doing some heavy gaming,but after that it went down to 23% according to gsam's app sucker on the % power used screen. I'm rarely in a low signal area, but when I am i'm not in that area for long enough time for it to really impact my battery.

I'm going to have to agree here. I think people are expecting way to much out of these machines. Especially if your gaming and browsing a lot. Assuming your not crippling your smartphone functions by disabling data and such,This phone is only rated for about 3 or 4 hours screen on time max, especially while gaming. 12 hours of battery is perfectly fine. Especially for the use case of the OP.

An exercise in battery longevity.

Hello everyone, im here to share my future experiences with seeing just how far i can push my battery and share how i did it with everyone.
Backstory:
I'm going hiking in Virginia tomorrow for a week, and would really like to have a camera without carrying extra devices, so..... its time to mod my nexus 5 as low power as possible!
here are some of the "prep steps" that ive done in order to obtain my battery life, i'll update the thread to let everyone know how it worked out!
Rooted
CM stable installed. (up to date as of this post)
Screen Brightness set to low as possibe.
Elemental X Kernel installed (Using TricksterMOD, these are my settings)
Multicore power saving = 2
CPU Freq. Lock= Min( 652800) Max( 652800) Max.screen off(300mhz)
Google Now/voice anything turned off
Home screen has only one page
Airplane Mode
Greenify Installed, Using Xposed Module for advanced/better control
Hibernating almost everything 3rd party, esp things like Facebook,KiK etc.)
BootManager xposed module installed, everything disabled that isn't needed.
Installed gsam for more meaningful data logging.
Unchecked Auto Sync Data in the Data Usage settings
Changed CPU clock min/max 652800
Installed Deep sleep battery saver Xposed module. (on slumber profile) buts phone into deep sleep when screen is off.
If i remember anything else i did on here, i'll post it.
(sorry its taking so long for replies/updates, "new user status" prevents my posts 5 minutes in between.) (hard to believe, been a member since 2011, just lurked alot.)
*May have found lower limit on the CPU, no instability as of yet, however phone is acting a bit erratic, looking into this currently. (booting takes FOREVER. this is a problem.)
*Trickster seems to pick and choose sometimes whether it wants to listen to me, sometimes CPU freq. on sreen off is changing to 652800 on its own. :/ anyone know of a way to get it to respect my settings?
*Changed CPU freq. to min max 652800 based on advice of the community.
Usage scenario:
I'll be using my phone mainly for pictures throughout the trip and possibly listening to some music, anytime its not in use, ill be turning it outright off, however, id really like to see just how far i can take this.
Anyone have any other suggestions for longevity?

Don't forget Google Now and Auto Syncs. (uncheck Auto Sync Data in the Data Usage settings).
Check out this thread here for some more suggestions.
I've been able to push it pretty far even with an active internet connection, though most of the usage comes from reading Reddit or forums with Tapatalk. That was on stock with no root access.

It's possible that it will take less power to just put your phone to sleep when not using than booting it up every time you need it. Depends on how often you boot though.

I was thinking that as well, however it would be difficult to find that "mid point" if i had an emergency backup of battery bank to test this theory, i would. However, im going to be stuck in the mountains and would rather have the ability to take the pictures i want rather then pure data log expedition. Great insight/hivemind though.

Based off my experiments, it takes less than 1% of battery to reboot the phone though I would guess somewhere in the 0.5% range. In airplane mode with all of these functions disabled and in deep sleep, 1% would probably get you 6 hours of idle time or even more. Therefore I would only power it down if you won't be using the phone for at least the next 6 hours. Rough estimations of course, I think either way it would be pretty similar.
If the phone is not powered down you might be inclined to use more than you would otherwise.

Unfortunately I do not, just speculation based off what I've seen when monitoring current draw (using Current Widget) and the battery percentage before and after a reboot.
I do have shots demonstrating low idle drain with Auto Syncs and Locations disabled. On average I'd say my drop is about 1% over 5 hours of deep sleep, but it's always hard to tell because there's no way for me to know exactly when it drops without active logging which would interfere with the phone's deep sleep.

Generally speaking a reboot uses ~1% of your battery. If you're locking your CPU to run at only 300mhz I would just leave it on the entire time. Especially if mobile data is off and so is WiFi. Make sure you go into Settings > WiFi > *Touch the 3-dot menu* > Advanced > Disable "Scanning Always Available". I lose about 1-2% in airplane mode overnight over clocked with high quality sound driver from Viper4Android. Plus the Google now hotword activated everywhere but lock screen.
A while back I did a test with my N5 to purposely nerf its power to see how long of a SoT I could get with it. I did pretty much everything you mentioned in the OP. Locked max CPU frequency to match min. Lowest screen brightness, airplane mode, etc. I was able to get over 12 hours SoT. So if the N5 can get 12 hours with the screen on using the same setup you plan in using with the phone getting nice and warm... I don't think a week standby time is too farfetched as long as it's idle most of the time except for pictures. Depends on how much music you listen to I guess. Only problem is even with music saved on the device itself, running at 300mhz you're going to run into skips and pops. Especially when the screen is off. Music playback will be kinda iffy.
Good luck though and let us know how it goes.
Edit: Actually I was mistaken. I just disabled everything like location, sync, etc. Default kernel parameters except switching to ondemandplus governor. This was on an older release of Uber kernel. 12+ hours SoT with ~30% battery remaining!
Here's my post;

You'll suffer Lag I would think with CPU at 300mhz max. And likely use more battery than your saving with the phone struggling to process anything.
May have instability issues too. I'd rethink that.

I agree, but I think that if the phone isn't used at all besides some pictures here and there, it should be fine. If he plans on music playback he's going to have to raise the max frequency, no question. Music playback won't work reliably that low. I don't think lag will be an issue for him considering what's he's trying to accomplish with the phone, but I can't speak to instabilities with 300mhz as max as I've never tried it.

But if the phone is sleeping soundly as it should.... The max CPU is irrelevant if not being used. The lag and strain to run processes may hurt a lot though.

You let the music play while the screen was off for a few minutes or did you just play it for a few seconds? I have music stutter on screen off with frequencies higher than 300mhz. I get it with 729mhz. If it doesn't happen to you, awesome. Not sure why though. Do you have time to purchase an OTG charger? Might be worth looking into and they aren't that expensive.
http://www.amazon.com/Best-Sellers-...-Phone-Battery-Packs/zgbs/wireless/7073960011

Currently listening with screen off/on full songs. No issues. no time to purchase an OTG charger however :/

Updated main post to reflect newest enhancements.
Trickster seems to pick and choose sometimes whether it wants to listen to me, sometimes CPU freq. on sreen off is changing to 652800 on its own. :/ anyone know of a way to get it to respect my settings?

I seem to remember a thread somewhere on xda regarding a CPU's "race to finish". Basically a cpu will work as much as it can (or better said "is allowed) to finish each task after which go to a low power state, like a marathon runner accelerates on certain portions and then "coasts" to conserve energy or a a car running on a near empty gas stank. Since you have a couple of days left I would try raising the frequency (600,800 and 1000) and see what happens to the power drained. It would definitely help with usability, as well as enable using photosphere or panorama ( which take quite a few seconds even at full speed to process) if needed. If the power drain would increase by less than 10% I would call that an acceptable trade-off.
While there is nothing wrong with finding the limit of your device, I think that an external battery pack would be a much better solution. There are ones available for less than $20 that could fully charge your device twice,

It would definitely help with usability, as well as enable using photosphere or panorama ( which take quite a few seconds even at full speed to process) if needed. If the power drain would increase by less than 10% I would call that an acceptable trade-off.
While there is nothing wrong with finding the limit of your device, I think that an external battery pack would be a much better solution. There are ones available for less than $20 that could fully charge your device twice,

I remembered a discussion along those lines, ill bump the freq. to 652800 min max, and update the main post. An external pack would be great, but i unfortunately just don't have the cash at the moment. between the trip and i just ordered a triple monitor stand and a new wifi usb to play with nethunter

Screen Brightness kills battery more than you'd think

So the poor battery life on my Note 4 might have more to do with screen brightness than I would have expected. Unfortunately, most people posting their SOT's aren't doing it in a very scientific way, so it's hard to know what we should expect from these devices.
Here are my battery test results using PCMark for Android https://play.google.com/store/apps/details?id=com.futuremark.pcmark.android.benchmark
In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

thanks for tests im using my exynos version on auto brightness and generally get 6 hours SOT. i saw on alot of people s stats and people who has problems generally has google play services on their battery usage list and it definetly shouldnt be at there... its probably about location reports to google every1 should disable it from location settings it doesnt break anything.

Yes, location can be an issue, but I think that impacts standby time more than SOT. Currently I've done the following to help with location-related issues:
- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

last night with 10 hours sleep time. with wifi connected sync was activated for 3 mails. i just lost 2% and i didnt do anything special like you did. no greenify no root nothing i couldnt even install wakelock detector cuz its broken on kitkat without root.
. i just disabled some useless stuff like samsung store etc.. everything else is working. and on my car i generally listen music over bluetooth

Lux could help

Before I started tweaking, I was getting around 6%-9% drain PER HOUR! Disabling stuff without root only got me so far, then the xposed tweaks and Titanium Backup had to be used.

like i said i dont know whats wrong for some people its probably something you installed(skype maybe) or mostly about location reporting. even last night i left my phone at 90% when i get it this morning after like 10 hours it was on 88% like i said earlier wifi was connected no power saving etc just normal idle time nothing special.

I was testing without any apps installed (just whatever I used to record battery consumption) and it was crazy high. Then I started adding accounts and apps, tweaking and I got my standby time to be much lower, but SOT leaves much to be desired. I'm going to try using the manual brightness and see if there are any differences - I often find auto brightness to be too bright or too dim! No "sweet spot" found! LOL

Greeny can also help but may need root

I'd suggest changing the settings for your Battery Monitor Widget app. AFAICS it polls every 10 minutes so a wakelock occurs every ten minutes to save the data. Use something like an hour and see what happens. Also would highly recommend BetterBatteryStats, a free version is available here for members.

I'll try that, although that might only improve wakelocks, not screen on time.
BBS never worked right for me. Always complaining that it couldn't retrieve the stats or falling back on something else.

Wait, with the screen off? Then you have something horribly wrong with your device. Mine did a few % over a night. With nothing done to the phone to conserve battery at all. Snapdragon, though. With the update.

I loose only 2% for 7h of standby last night.

We are seeing a trend I think, I noticed that it's mainly us 910U users or exnyos users complaining about battery life. So it must be something in the 910U rom?

I've got a 910F and I get 6 hours screen on time maximum :/

Doesn't happen now that I've rooted and applied my standard tweaks, but I tried a factory reset to see if I could correct the high standby drain and was not successful without these tweaks.

I have 910f and i got same issues with my batt.
i've tried clean system, root, custom rom. Battery is always draining higher than some people.
As i said in other thread: some people have an issue, some have great battery life. And nobody knows why

Maybe it's the guys who keep it stock and don't root, custom rom and "tweak" that get the good battery life.

Delete it pls.

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Sony Xperia Z5 before depleting the battery.

Was using Intelliplug with eco conservative profile in kernel auditor. Also had undervolted all clock frequencies by 5 mV
Most of the other settings stayed at stock. The governor (interactive) was tweaked using heimdall's tweaks ( posted in z5 themes and apps section by a user, along with those power tweaks and setprop tweaks)
I felt amplify made most of the magic here. Helped a lot with wakelocks. Searched the net for guide to use amplify and it worked brilliantly. Phone was down to 50% and I had an SOT of 4.5+ hours.
Will try the new kernel and let you know in a day or two. I am pretty sure the kernel would work better if I gave it a day to settle.
For the previous kernel which I was testing, it was it's first run.

Pretty sure I can get it to around 8 hours SOT atleast! But since I am very busy nowadays and my internship started today, it's gonna be a little hard

Best for me is 4:48 as reported by Battery Monitor Widget, but mostly is 3D games so I think is pretty good

I have my Phone 3 hours off Power, Battery goes down to 60% and the main app draining power is the Display with 17% as per the battery consumption chart.
In the Details to the batteryconsumption of the display it says the display was on for 1:35, however I hardly turned it on.
That is the same since LP and even with MM I reset already 3 times. no change.
I would love the meet someone with that great performance. mine seems just broken :/

I get 5 hours on average from 100% without using Wi-Fi and on H+ and my average use is what's app, Instagram, mobile payment, snap chat ( eats a lot) and taking pictures. My brightness is at half with automatic turned on

Actually I hope so. I am one step away from rooting my phone and hope that this might help, especially with greenify having root access.
The device is almost unusable anymore with this battery life. I factory reset once a week, don't even have many apps or do much with it but it still lasts just half a day.
After a factory reset the first 2-3 days are almost fine up to one day.
I dont even think 2 days are possible if I don't activate the whole time...

Xperia Z5 Tmobile USA
2.5HR SOT
Mobile radio likes to stay active throughout the day. Have tried many roms/ factory resets.
Hopefully next software update....feel like i've been saying that for years about various android phones...

Similar here on T-mo USA
I wonder if the lack of proper tmous radio tuning leads the phone to drain on LTE... Have noticed more drain (phone doesn't seem to have doze lines anymore even though BBS shows doze..) after rooting/xposed. So much that I uninstalled xposed as a test.
Going to try dropping back to HSPA and see if its better.

Not sure if that may attribute to it but i dont doubt it...
I did have the courage to flash one of those US roms, even though my FPS (fingerprint sensor ) didin't work...
But eventually after a few days, battery drain came back....

Hmmmm may be onto something here, right away I'm noticing that Yappy is not hanging on sending messages. What I think was happening for me was low LTE signal was causing Yappy to wake up every minute to restart itself. Not sure why Yappy wasn't showing in battery settings, but my phone seems to be connected now that I'm on a 'stable network'. Really wish we could get the tuning on tmous :/

I'm getting average 7-9 hours SOT with my Xperia Z5 Dual E6683... btw is it normal for the GPS indicator at the battery usage page to show that it's constantly turned on throughout the whole day eventhough it's turned off?

Aaaand nope, got the fast dormancy wakelocks and battery drained faster than before. Reflashing the stock system and wiping cache now to see if I can get doze lines again.
Edit: Battery is better but I think because of things I did after reflashing. Installed WLD since I have root now and noticed that google maps (and later android pay) were generating NLP wakelocks, so cleared data on google maps since I have location reporting off already and then denied location to android pay and it seems to be back to normal. If this is stable for a few days I may try Xposed again.

On average daily use with WiFi on and location enabled most of the time I will get 5 hours SOT. I have pushed it close to 6 with reducing my brightness to almost nothing and only using the phone for messaging. Several factors will affect SOT. For me getting group messages or picture messages drops battery life. Using Chrome also drops it.

Are you asking the app usage in the day? Funny enough my battery life today was a definite miss but it got me through the workday and that's all I need.

Nah I meant like what apps do you have that are non-stock..
But looks like my phone is back to not dozing.. losing ~10% overnight, where I used to lose 3%. Looks like I'm getting the Mobile Radio Active bug displaying through google play services. Clearing caches of apps that appear to be causing it as I go...
