Sudden dip in standby battery life on grouper - Nexus 7 Q&A, Help & Troubleshooting

Hi guys,
I got a 32 gig grouper off Ebay in July 2015. From the get go, I was impressed with the battery life, and it got even better when I went the custom rom route. My main use case is streaming movies or TV in the evening for a few hours, and otherwise leaving it in standby/airplane mode to conserve battery life until the next viewing. Typically overnight, the battery sips power -- maybe 2-3% lost in 7-8 hours.
Over the past month, though, I've seen a considerable dip in the standby/airplane mode time in particular. Now, overnight I seem to lose 10-15%. I realize batteries have a lifespan, but I figured I'd see a more gradual drop?
I tend to only have 4-5 streaming apps on the tablet at a time. Currently I'm running CM11 stable, but I observe this standby battery drop in all roms -- I've gone as far back as 4.1.2 (stock + unrooted) and all the way up to CM13 unofficial. I used better battery stats/GSAM but never really caught any wakelocks that would account for that much power lost.
At a loss for what to try next. I can capture screencaps if it helps, but they never really told me anything (perhaps someone else would get more info from them.) Any help is appreciated!

Also, my on screen time feels about the same. I've drained the battery a few times with some streamed video, and I get around 4-6 hours. It's the standby time that has dropped off considerably.

Get Kernel Aduitor or a CPU managament program and see if your tablet is going into deep sleep or if it's still at another clock frequency or if a program is keeping it up.

Thanks for the reply!
My N7 is in deep sleep about 80% of the time on a typical charge, the other 20% being used for on-screen usage (video streaming and browsing typically). It's maddening -- I now lose 15-20% on standby/airplane mode overnight. I don't see any flags in better battery stats or GSAM battery monitor. Most apps are greenified, too, and location services/other potential draining factors are disabled.
Is it just a bad battery?

[Q] Desire Z : Really Inconsistent Speeds + Battery Issues

Friend has a new Desire Z (bell, unlocked). Using it on AT&T network.
When at a house, and we use WiFI (30Mbps DL, 25Mbps UL), the speeds are VERY inconsistent. With my iPhone 4 using speedtest.net, it shows up as 20/15 each time. (WiFi is a little slower than the modem).
With the Desire Z, we get 15/10 (which is fine/acceptable). Then 3 minutes later we do it, we get 5/2. Without even moving the phone or touching the modem connection (not downloading anything on the computer), the connection just gets slower. Then it might be fast or slow, basically it's a toss-up.
The first time we noticed the issue is because when we are outside, we get HSPA speeds of 2.5/1.0, then randomly decreases to 0.1/0.05. HUGE difference. And VERY inconsistent. He is using a microSIM from iPhone 4, with an adapter, so we figured maybe the SIM card is getting loose at certain points? However, the WiFi is also inconsistent in addition to the HSPA, so it's probably not that.
What should I do? Is this the situation where I have to flash a new radio or something? (Please suggest others if I am wrong).
Thanks!

Also, his battery is kinda weak. The battery health is apparently clean/healthy. He came from an iPhone 4, where he would have 3G, WiFi, and GPS on at night but not actually using them. Wake up, and 3% battery loss, maybe 5. WITHOUT using them, just having them on.
Now, with the Desire Z, we have the WiFi + 3G on, but NOT the GPS. He is losing 20%-25% in 8 hours without even using the phone.
Information about battery shows a high Cell standby (25%) and Phone idle (25%) percentage. When going into Spare Parts > Partial Wake usage, we didn't find anything really fishy. BUT we had rebooted so perhaps some info may have been lossed. Should he just go to sleep tonight and report the Partial Wake Usage statistics again?
We have a feeling it may be some apps refreshing at night.. But he clears all the apps with Advanced Task Manager except for like Facebook (2 hour interval refresh), GMail, and Google Voice.
I highly doubt a 20% battery decrease overnight is normal.. My mom's Atrix only loses about 5% overnight, with the same parameters I gave before.
I thought it may be a bad battery, BUT the phone idle + cell standby are abnormally high.
Thanks!
Why is this in General as well as Q&A?
Put this in Q&A, didn't get any answers. Went to General, saw that more people posted there, even for Q&A's. Have an actual problem that research didn't help much with, so made a thread. If necessary, I would be glad to remove the thread on Q&A.
By the way, thanks for the answer .
Would you be able to post your software specs? Radio version, rom version, android version? My Bell DZ only loses about 3% per night if I don't plug it in to charge. I, like you, have wifi, gps and hspa enabled with no huge I'll effect.
The stock battery is usually alittle weak. Being a 1350mA, it doesn't have the capacity either, but that is why it is user replaceable. I picked up the mugen 1800mA battery that gives the phone the stamina to last a full day of full use or 2-3 days of light use. I forget how much I spent on it but it was definitely an upgrade.
As for the signal issues, we would need to know what you are running. The latest .30 radio is recommended for AT&T if I remember correctly. Also, the type of rom (stock or custom) might give us abit more insight.

I lost about 10% overnight today I believe, possibly 15 (don't remember exactly what I left off at).
Not sure on all the stats because I don't know how to check them but
Android Version 2.3.4
Cyanogenmod 7.1.0-RC-Vision (seller did it for me)
What is the radio version? I think that is baseband not kernel? If so its 12.52.60.25U_26.08.04.30_M3
-------------------------------------------------------------------
If anyone knows about the sporadic data, that'd be helpful. It does seem that if I go into airplane mode a few times it fixes itself, but I doubt everyone does that to ensure fast HSPA speeds

I've never used CyanogenMod Custom ROM's before, so I can't speak from that experience. I can, however, tell you that while running RMK (and team's) Custom ROM's (Virtuous, G-Lite, Unity) and now MIUI, battery life has been excellent, even with the stock battery. The current build of MIUI lasted for about 15hrs on a day of full use, RMK's ROMs would last about 12-15hrs of moderate to full use on the stock battery. Alot of the custom roms have different power management settings and tweaks, if you're comfortable with flashing, I would recommend another ROM and see if that helps with either of your problems.
If you like the Vanilla/AOSP look of android, try RMK's G-Lite ROM. It is very lightweight, fast and stable. I remember having one issue with it, but it was a very small issue and didn't stop me from using it for a few months.
I am currently on MIUI English 1.7.1 and with moderate use I am sitting at 50% charge spent over 2 days. Moderate for me is about 300 texts with about 10 phone calls and a total of about 4hrs of web browsing.
I can link you to those roms if you need, but they're all located in the Dev section. Your radio seems like it's on the right version, so perhaps it's not the issue. Try running another rom for a week and see if that helps to any degree.
I re-calibrated the battery, let it die, charged it up, let it die, charged it up. I followed the instructions to the letter and all that.
It was at 100% when I went to sleep. Woke up 8 hours later, 74%.
Settings > Battery shows nothing high 40% for cell standby and phone idle. Everything else (Facebook, etc.) REALLY low.
Then I went to Spare Parts > Battery Usage, Partial wake usage, everything incredibly low as well..
I will try Watchdog, but could it just be a bad battery? Or maybe should I try a different ROM?
Thanks!

NO! This is poor recommendation, and people need to stop perpetuating it. People keep recommending this, but its NOT a good idea to let the battery drain until it dies, just to calibrate the battery meter. While the protection circuit on the battery will USUALLY prevent over discharge, it is not 100% failsafe. There is a slight possibility that over-discharge of the battery will happen, and then the battery is no good, and will need to be replaced. Unless you have a special battery meter with a "boost" function (which most people do not have access to). See the following table on Battery University, where it says for Li ion batteries: Discharge: Prevent full cycles
http://batteryuniversity.com/learn/article/do_and_dont_battery_table
Best practice is to charge to 100%, drain to about 20%, repeat a couple times. No need to go below 20%. The battery meter is not very accurate to begin with, so there is no value added going to 0% versus 20%, but you risk killing the battery.
Plus people keep abusing the terminology. You are just calibrating the battery meter, not "calibrating the battery". When people say this, I think its just a holdover from the old days of NiCad batteries, where you had to condition/discharge the batteries periodically to prevent memory effects (Li ion batteries do not suffer from memory effects, and require no period cycling).
Can't really speak to the Atrix or the iPhone. But the battery drain on the DZ described by the OP is right in line with what I've seen. I also have an unlocked Bell DZ on AT&T, and battery drain of 2-4% (on various ROMs and couple different radios) when the phone is completely idle, screen off is totally normal. Best I've seen on my DZ is with the Virtuous Unity ROM and the .30 Gingerbread radio, where I've seen somewhere around 1-2% drain per hour when idle.
One possibility, is that the different phones are not reporting % battery the same way. As I've mentioned above, the battery voltage meters on phones is not very accurate, maybe in the range of 5-10% accuracy (although, even with this, the drain on the DZ versus the ATrix and iPhone still sounds inconsistent). But what is more important is how many hours of usage you get before needing to charge.
Thanks for the info.. Ill try charging that way.
And I honestly think the battery is just reading it wrong. It honestly feels like it dies faster idle than not, go figure. Yesterday, at like 10% battery, I wanted to kill it off, and played a game for like 10 minutes straight, still 10...
Then I tried leaving the flashlight on for 10 minutes on and it maybe lost 1
How is that battery I recommended from dealextreme though?

It's interesting to see all the troubles that people are getting on the DZ...
I've had my DZ for about 6months and never seen any of the reported problems.
My 1350mha will last me on a frequent usage near 24hrs and if I'm using it lightly like when i'm busy at work... almost 2days worth.
Mind you I'm running Cyanogen MOD7. No GPS. Wifi is on and I use JuiceDefender.
Cheers mates.
Last night, I charged my phone to a complete charge before going to bed to see what kind of drain I would see overnight. After 9.5 hours, my battery had only lost 2% sitting idle. That is with 3G on, but no Wifi or Bluetooth enabled.
The phone idle accounted for 47%, cell standby 48% and Android system 4%
While it seems remarkable, I'm still not convinced that its not my phone incorrectly reporting the battery level. On a typical day when I pull my phone off the charger, the first 10% is very slow to drain. Today, I have sent a few text messages and played maybe 3 minutes of word feud. That has drained 6% of my battery.
We will see where I'm at later in the day. I suspect that the actual level is lower than the 94% it is reporting. Typically, I get between 12-16 hours of usage, depending on how much I play with my phone.
Well I am at nearly 23 hours on this charge. Have used the phone rather lightly during the day. It sat idle for about 9 of those hours while I slept last night.
Conclusion: Idle drain is very minimal on my device and looks as though the percentage was being reported rather accurately. I'd say if you're having a lot of drain while sitting idle, do some digging and find what it is.
More info:
Facebook: update 1 hour
Gmail Sync: 1 hour
Fancy Widget update: 1 hour
Brilliant Quotes widget: update 1 hour
Light Bluetooth usage (about 15 minutes)
Wifi on all day (not overnight so about 14 hours total)
Screen brightness set at about 50%
Average signal strength: -100dbm

[DISCUSS] Battery Life.

Most threads about battery are quite outdated, so I decided to start a new one.
And so recently my battery is starting to get less muscular.. My Xperia Play is 4 and a half months old, and one hour of consistent 3G usage can drop the battery down from 65% to 24%. I'm not very sure whether that is the norm, but if it is, that's bad battery life, in my opinion.
The Android 'Battery Use' page shows that most of my battery is drained from Cell Standby and System Idle (30%).
My wireless and GPS is always off. Am on 2.3.4 rooted.
Also, Gameboid consumes battery like a beast (even more than 3G), but I guess that's due to the high processing power required for emulation..
Is there any way I can improve the battery life?
Personally I found battery life to be terrible on 2.3.4 so I downgraded to R800i_4.0.A.2.368_World. I'm running 122M-1.5Ghz with scary and BFQ, on top of that I undervolted every frequency as much as I could using incredicontrol (Id give you the values but they vary by device). I always leave wifi, bluetooth, gps and data off when not using them, turned off automatic clock updates (there was a battery draining bug with this a while ago) and I run at 10% brightness with autobrightness off. With this set up I lose maybe 3-5% per night, so for around 6-8hrs in standby while I sleep. Ive got similar results on both cyanogen and stock. That being said I don't have a data plan so I do save a lot by not having data on, but a 40% drop in an hour isn't normal - Ive played an N64 emu which runs the processor full speed for that long and only experienced a 15-20% drop.
imho, the best battery life i've experienced is on 2.3.4.. when i'm on 2.3.3 i always lost 30-40% overnight (wifi, bluetooth, 3g, etc are turned off) stock rom, locked BL..
According to some folks, if you're charging your phone and let it stay plugged in for a while after it hits 100% that screws with the battery life.
On 2.3.4 rooted with all the facebook, timescape and other bloat removed my battery is pretty good. Wifi is on 247 and it reverts to hspda when out. Data syncs hourly, and i have contacts, hotmail and gmail syncing.
The other day i was sitting at 57% after 1 day 3 hours, and that included a half hour go on fpse, might have been more.
Battery life seems good to me. I get 1 day usage then charge over night. I do use my phone quite a lot for this (Tapatalk), Phandroid app, Engadget app, Joystiq app and browser. Wifi and GPS is always on.
At a guess I'm using the phone for about 1 hour a time, about 7 times a day... So like 7 hours web use, phone calls and texts, syncing is set to every hour with FiX on.
When I was on 2.3.3 I'd be lucky to get 10 hours out of the battery but 2.3.4 is awesome.
Edit. Obviously I play games too. Forgot to mention that.

Actually I get similar idle battery drain rates as you, but personally I'm not very concerned with battery drain as long as it's not so much. I'm more troubled with battery life on consistent usage, which I feel the Xperia Play (or at least mine) sucks at.
When I play Gameboid, I get the same fast battery drop too - 40-50% in one hour.

Yep, I read that from a lot of places too. I admit I used to do that (and have since stopped doing that), but sometimes I can't help it if I forgot to charge at night before I sleep (and have to charge overnight to ensure I have battery the next day).

And did you remove the bloat stuff by deleting them from /system/app?

Sigh, I could never get such good battery life..
All the more reason to undervolt, in standby undervolting doesn't have much of an effect on the phone since the processor is either in deep sleep or running at its lowest speed. Also using a governer like scary or smartass helps keep your device running at a lower frequency when possible. Like I said 2.3.4 was terrible for me, 10% drain overnight or more, but apparently YMMV with this. That being said 40-50% drain in an hour is crazy no matter what you're doing on the phone, like I said running N64oid for an hour drops me 15-20% keeping in mind this is at 1.5GHz with sound and the backlight constantly on. If all else fails you can always wipe everything and start fresh, carrying over the same settings while jumping around firmware can lead to some undesirable results. Anyway good luck and keep us posted
The facebook sync option doesn't appear on my anymore, although it used to. To clean it up all i did was :
Purchase Titanium Bakup
Freeze the things I wanted to remove and test rebooting, only freezing a few more each time
Backed up every app
Slowly uninstalled each one with a reboot every couple of apps
Enjoyed my faster phone with better battery life
I use the gmail sync and life.contacts for contact pics
I get amazing battery life on 2.3.4.
In stand-by I lose 1% every 3'rd hours. It's very good in use too. Yesterday I had my day with heaviest use so far and texted like crazy the whole day and a lot of phone calls. Some surfing, gaming and updating of apps between that. Basically the phone was frequently used the whole day with short periods of stand-by in between. At night when I went to bed the battery was at 40%.
Earlier this week I used it minimally for 2 days. The battery dropped 10% for each of those days. But that was very minimal use.
So in short. I have not experiences better battery life on any other Android phone. What takes the most power is emulating. It can suck up like 20% in an hour depending on which emulator I use.
I got my Play at the beginning of the week and with quite intensive use, without WiFi or 3g, I scraped an 8am to 6pmish day on the battery. Admittedly with a fair bit of gaming.
However, that was only waiting for my 2600mAh battery to arrive and now I'm using it, I would recommend it for the bulk. You don't notice it after half an hour or so and I have no issues with gaming on the go whereas I always thought it may die on the stock.
mine drops 4 - 5% /hour..... much faster than b4.... dn no w is goin on w/ ma PLAY.....
I found that since updating to 2.3.4 my battery drains quicker. Usually charge overnight and battery would be around 15% bedtime. (7am - 11pm approximately)
Now I'm finding that by 6pm I'm having to charge it and that's without gaming
brought to you by the XDA app on my badass Android toy
Three times in my first week and a half of ownership I awoke to find it completely dead despite fully charging it or nearly fully charging it before bed. I usually sleep with my phone next to my head so that I can ensure that the alarm will wake me up. That and the lack of a timer function really irk me about this phone. I really hate having to create and save an alarm when I know I only have 45 minutes or 2 hours to sleep (I work a grave shift and have inconsistent sleep schedules during the day). It adds insult to injury when something changes that lets me get another 5, 10, 20 minutes or so and I can't easily add it. On top of that, I have to go back and delete all the alarms I made throughout the day!

Thats crap. Infact you should leave your phone plugged in a good 30/45 mins after it says fully charged if you want a full charge

Not at true max but at what the battery controller considers max. True maximum will drastically decrease the total cycles just like true minimum only to gain longer cycles in the short-term. When you store a battery it's best to stop at 75-80% because it will lose stored energy slower and not spend nearly as much time near 100%, which is still a trade-off between long cycles and more cycles.
What do you guys think to this?

Its the same size as the standard stock battery so there's no extra bulk... But gives an extra 930mah?
To be honest, I am somewhat tempted... However the question is, will it explode in my pocket and result in me losing half my leg? It's quite a big risk to take! There also might be a voltage difference, however I cannot see anything on that.
Im currently on 1.6Ghz, undervolted. And I just played Order and Chaos for 35 minutes and went from 86% to 63% - I've had bad luck in the past regarding phone batteries, I remember replacing my G1 battery around 7 times, but at these rates my Play would be dead after around 3 hours or less of gaming.
how do you update to 2.3.4 it wont show me =[ please someone answer me :/

You have to expect that with any phone playing an online game. Wifi/screen/GPU/CPU are going at full wack at the same time. What dya expect?

Battery drained in 12 hrs (screenshots included)

- I tried removing a lot of thumbnails to combat the mediaserver drain
- I removed a clock-app that constantly used around 4% cpu
- I tried removing facebook and google now or whatever their weather/intelligent widget is called
- I tried using greenify on everything i could think of.
Today i woke up to a phone that had a depleted its battery more or less overnight with just 30% screen on time.
I did experience the phone lasting 2½ days without a charge during my holidays and that was with 2 hrs screentime and 35% left. That's the kind of performance I'd wish for. The phone is rooted, and I'm using solo launcher, but hardly any customization that aside.
I took SCREENSHOTS of everything that might be important. Maybe you can tell me whats wrong. Under cpu states it says 1khz and only that. Isn't that a bit odd?
https://www.dropbox.com/sh/srbcydgcrjv9bu1/AABWYUDSjS9ElVbnm0MY1w9ha?dl=0
IMO that's not too bad I have a 7200 mah battery and it last me about that longs with around 4 hours of SOT, but it seems like your phone might be clocking too high, and brightness might be too high for the screen to be the main suspect like that, with only 30 mins of SOT
I think it's linked to the 3g/4g. If I disable that my phone will last significantly longer. I spend roughly 2 hours on transport a day. Conversely during my holidays it stayed in and around a summerhouse for 2½ days on one charge with 3g with long screen time and camera use. That's a hypothesis at least. Also I didn't use google music or any other audio player at that time.
I can get 2 hrs of SoT, but then I have to actively spend all the battery in the first half of the day, because after a full day the battery will be more or less drained regardless of SoT
If you don't ever use your printing features then i would delete those apps also because the printing service are usually turned on by default and searching for something to connect too or make sure its turned off in your ROMs settings so its not constantly searching.
90% of the time that unexplained battery drain occurs it is caused by low signal and the phone constantly trying to lock on or find a better signal. You can try to decrease this drain by using wifi in low signal areas but your phone will still drain your battery if the voice signal is low to. My phone lasts all day and then some when I'm in good signal coverage. When I go to my brother in law's house which is out in the middle of no where my phone will drain the battery in a matter of hours.

Z3C rarely goes into deep sleep

Hello,
I used CPU spy to see if the phone went to deep sleep during the night and after wake up I saw that from the 7 hours, 4 hours it was in deep sleep and the other 3 hours it stayed at 300 MHz.
Is this normal? The night before I didn't charge the phone and it lost 9% in 7 hours during the night which I think is too much.
My phone isn't rooted so I can't find what is causing this, is there any way? Or any recommendation to fix this? The battery is pretty good but this is still annoying.
BTW I have 3G and WIFI always on, but no BT, no locations, no google search, google+, etc. activated and the Power Management settings doesn't show any drainning app at any time.
Thanks in advance.

For me the battery during idle seems to vary. I have seen it deplete at around 1% an hour or 2-3% for an entire 6-7 hour night. My guess is that it is based on my usage before bed. On some nights i might've used an app that triggered a wakelock and other times not.
I am heavily into homescreen customization (and rooting-however not for this phone yet, without the exploit) and have widgets and animations everywhere. (like the homescreens you would find on mycolorscreen). I also have a good amount of apps. The potential for a wakelock is certainly there. Considering those 2 factors i would say the battery for this phone is extremely solid compared to any devices i've used in the past.
I have also had instances where if i am at a meeting or doing an activity and don't touch my phone for several of hours the battery life stayed at the same percentage or only dropped 1%. So the phone does indeed go into deep sleep.
Overall, i don't think the standby time is bad enough for me to complain or investigate.

Yes I see what you are saying, the phone doesn't always behaves the same way.
I just don't like the thought of some app draining my battery for no reason, maybe it's the e-mail account. I can't complain aswell, I got 2 days of battery with 6.45h SOT this weekend I guess that's great, 9% during the night was too much though.

If it was a one time occurrence I wouldn't worry about. If it is 10% every night then I would look into it

I had battery drain of about 4-5% overnight at first, but after going through all the apps and disabling any parasitic menu options (like phone-home data logging), setting Wi-fi to turn off during sleep, disabling app syncing overnight and disabling or uninstalling unwanted apps installed by Sony, I'm down to about 1-2% drain overnight, which is about as good as it gets. And that's without Stamina enabled -- I set that to kick in only when the battery is below 50%.

Wear24 battery life improvement?

Hey folks,
Just curious if anyone has seen battery life improvements since the most recent wear OS app update?
Initially afterwards I saw normal battery life. However, I ended up being without a charger Saturday night due to an unplanned inability to drive home from a friend's house. This resulted in me powering down the watch overnight, then running it to dead on Sunday. Recharged overnight, and today this is what I'm seeing for battery life...
This is my normal configuration (BT connection to phone on, WiFi on, GPS off. Screen always on, same watch face I've been running for 5 days).
Interaction was at normal, or maybe slightly more than normal level today, as I was in training class so I responded to a couple things on the watch that I normally would have used phone for.
Really just curious if anyone else is seeing a change, since I can't figure out what, if anything, I did to make this happen. I'd love to see it continue, as it's about half the battery drain I'm used to seeing. Usually get about 22 hours estimated up time, something like 4.8% drain per hour. This shot shows steady drain of 25% over about 11.5 hours or like 2.2% per hour...

Same here I'm getting twice the battery life on my wear24 hope it continues

And you saw the change start since the last update? Have you run it fairly low since the improvement? I plan to charge tonight, but curious if it's actual improvement or a reporting error (so it'll die at like 50% or something).

I've run it down to around 30% it took over 2 days lol and charged it back up I don't think it's a reporting error

Nice!!
I'm totally baffled as to how you guys are achieving this kind of battery life. I've had the watch for seven weeks and I've never eked out more than about 18 hours.

I've been using this guide since I first got the watch for battery saving setup:
https://forum.xda-developers.com/an...-battery-tip-wear24-lte-aw-watches-3-t3729680
This initially got me the roughly 22h up time and 5%ish per hour drain.
The only things I'm aware of that could have a (slight) chance of triggering this recent improvement are:
Update to wear OS software
Ran watch out of power (possibly giving the battery better calibration data?? Forcing a reboot after the update).
As of right now today isn't quite as good as yesterday (76% left at just over 8h off charger, so 3% per hour). Essentially identical usage to yesterday in same locations.
I dunno.
Thanks. I've seen that post. The guy swears by airplane mode. But if I have cellular disabled and wi-fi off, I'm not sure why it's also necessary to put the watch in airplane mode.
I'm sure that some of my watchface choices have an effect on battery life and I'm willing to accept that (and save the less-efficient faces for days when I'm mostly home), but I should still be able to get through a long day with power to spare, which is not always the case.

I do run airplane mode 100% of the time. No haven't really tried without it to do a comparison.

Reportedly it still polls for Wi-Fi if you have it disabled. They state this stops in airplane mode saving a bit more battery.

The Wi-Fi polling may be part of location services?
I'd be willing to try airplane mode if it didn't put that little plane icon on my watchface.
battery improvement
I noticed my wear24 battery time got significantly improved today.
Is anyone else seeing on their watch? imgur.com /a/aUSCEQl
Shortly after I originally posted this, mine went back to what I'd call typical. However, the last few weeks it's been better again. I'm usually seeing between 50 and 75% battery remaining after a 16-18 hour day off the charger now. Seems to be better with facer and pujie black faces thanc with watchmaker, but the difference isn't huge.
my moto 360 first gen
only last 4-5h now. and turns off at 37% great
maybe need a new battery. buying one for 11€ hope that gonna fix it
Anyone else's wear 24 battery starting to go bad? As of the past weak I can barely make it 12 hours with minimal use. It's as if the battery life has been cut in half.

Occasionally I get bad days, but, as an example today with minimal use I've had it off charger just over 11 hours and currently at 60% battery left. I'd say normal is around 20-22 hours usability.
Newest update has increased my battery life dramatically since a few days ago! Others are commenting on Reddit about it.
Same here. Getting 2 days of battery life with Airplane mode On; then Wifi/BT on (3G/LTE off).
