Develop Bugs

Greatly improved battery life (CDMA)

Last night I restored my phone using the factory image. For some reason I anticipate an OTA soon so I wanted to be ready. Anyhow, before I suffered from the battery drain bug. I forgot to charge my phone last night, and didn't realize it until I got in my car and put it on the car charger and it said 89%. My first thought was that my battery drained over 10% in the hour I was getting ready and not using it! Then I went into battery settings and found out I never charged it.. then I found some pleasant... well, I'll just show you.

As you can see, I lost less than 5% battery during the 6+ hours my phone was unplugged. I had the phone in the living room charging while watching a movie. Then I unplugged and used it for about 20 minutes in the bedroom which accounts for the first rapid drop in battery. But after I set it down, the phone went into a coma. And I can't see exactly, but it looks like it was only 2 or 3% which is great!
Not sure what changed, I still have the same apps installed, even Facebook. I did, however, NOT disable VZ backup assistant like I normally do. Maybe that is what causes the OS to go bonkers? Thoughts?

I got about 20 hours out of mine yesterday (extended battery) with moderate usage (texting, ebay, facebook, web) This is after unlocking the bootloader and rooting. Unlocking the bootloader resets the phone to factory state. I've read a few other posts around the web where battery life is greatly improved after a factory reset. Android OS is still the main things devouring my battery, but I almost don't care with the performance I'm getting. I should also mention that I wiped battery stats from CWM and then calibrated the battery on first charge.
I'm no dev, so I don't know why a reset would help. Then again, maybe it was wiping battery stats and calibrating that helped me. Just my $.02

How did you calibrate the battery?

There's a free tool in the market that will calibrate for you. Have to be rooted though. Just search for calibrate.

Surprised this isn't getting more acknowledgement. Any one else experience the same after a reset?

Guess maybe I'm one of the lucky few...I've always had this type of battery life. The phone just sips power while the screen is off.
While it is on...well that's different. I keep the brightness high and get about 2-2.5 hours of screen time before it powers off.

The interesting thing here is that it seems that you have the Android OS constantly waking up the phone but yet it still barely uses battery.
Do you have location services turned on or off?

Turned on. I noticed that too but the overall awake time is low. Usually it would be over half of the entire time on battery, sometimes 100%.

I used 50% in about 3 hours on my extended battery.
fml.

Great battery life, but you didnt really use your phone much.
Your "Screen on" is only about 15% of those 6 hours. Which ends up being about an hour.
Still, none the less, great battery life/power consumption.

I think you missed the point. I said this was done while I was sleeping. Many people are experiencing extreme battery drain even when they aren't using the phone, as was I. After restoring from the factory image, my issue seems to be gone.

I unplugged my phone at 11:30 pm with 98%, woke up at 7:30 am today and it dropped to 76%. So a 20% drop in 8 hrs with the phone just sitting there with wi-fi on and no apps running. It'd be very interesting to see if a factory restore would help.
How's the battery life now that you're using it?

Im thinking of unlocking and rooting mine tonight. havent had a moment to read the walkthrough just yet.

i noticed this too last night/today. i went to sleep after installing bugless beast 4.0.3 cdma, left it off the charger, and today i saw the chart was pretty much a flat line. i don't recall the exact times, but i'll try to time it out. about 8 hours
i wonder if all the initial extreme battery drain reports are due to the 'wowanewphone' effect, where you are molesting your phone 24/7, as opposed to the typical day-to-day use you'll eventually fall back into

Battery life + great battery monitoring application

I just got my Glide a few days ago. From the specs of the phone and reviews online I was expecting the battery to last very long, but that hasn't been my experience.
My battery was going down about 10% every hour which means I would barely make it through a work day without charging it again.
I found a great app called Battery Mix that tracks battery usage and estimates how long the battery is going to last. It shows a number called P/H (percent per hour) which tells you how many percent per hour the battery is going down (or up if you're charging). You can find the app here: https://play.google.com/store/apps/details?id=jp.smapho.battery_mix
When I first installed the app I was getting about 12.5 P/H which means the phone will only last 8 hours. I then uninstalled a few apps that use battery, but that didn't help much. Somebody said their battery improved when they formatted their SD card, so I just removed the SD card from mine. Now my battery consumption is down to about 8 P/H. The best I've seen is 7 P/H. This is better but still would only get me 12 hours and I'm not running all the apps I would like to be running.
I have JuiceDefender running now on the balanced setting. I'm running the Osimood ROM with Android 2.3.5. I've removed all background network polling apps like Facebook. Android OS is using 56% of the battery followed by display at 15%, so there isn't anything else that's eating up my battery.
How is the battery life on your Glide? Could you please install this app so we can compare numbers?

Woah, 56% battery life for the Android OS?
On daily usage it barely gets above 20%. The screen takes most battery life.

Thanks for the info.
Mine has been sitting on standby most of the day so that's probably why display is so much lower on mine than yours.
The high percentage of Android OS doesn't really worry me. It doesn't mean it's using a lot of battery; it just means it's using most of whatever is being used which could be a small amount.
Mine is doing much better now. P/H is down to 4.3 which means it could last 23 hours.
I really think the problem was the SD card. I'll pick up a different one after work today and see if it works better. I need a bigger one anyway.
I also found a thread that talks about corrupt image or video files on your phone causing bad battery life. That could definitely be what I'm experiencing. Should be fun figuring out which image is causing the problem.

what about downclocikng your cpu to 800? it will help i belive.

OK just installed it. I will let you know how mine is doing in a few days. I am fully Rogers stock.

I replaced the SD card and it seems to be doing better now. There may have been images on that card contributing to the problem.
I actually had GPS, wi-fi and bluetooth on the whole time. I've turned them all off now.
I've also underclocked it to 800. Thanks, taiber2000.
It looks like for the last hour it only dropped 3 percentage points.

If you are rooted and have ClockworkMod installed, you can sometimes get better battery life by resetting your battery stats. I think there are even some apps for rooted phones that will do it, but I don't have any experience with them. I can say, however, that resetting my battery stats using CWM increased my battery life significantly.
See here for one guide on how to do it: http://www.droidforums.net/forum/bugless/111009-get-better-battery-life-reset-battery-stats.html

sjbotha your welcome.
i belive i will do the same when i'll get my phone as well. altugh i will install the OC rooted kernel for better overall performance i will still downclock via software, not need the extra sterngh for my uses and i better have longer use time then CPU power.

I get 4.9 but the other day I was getting 12. All I did was Reboot my phone and I haven't started many apps. I think when they start they stay in memory.

Mine depends on usage:
-about whole day wifi-on with 3 hours games and calls; if battery is 100% at 6am, it will be 20-30% at 10pm
-whole day HSPA+ on, 2 hours phone calls + SMS/MMS, emails etc; if battery is 100 at 6am, it will be 50-60% at 11pm or before I sleep...
in terms of P/H:
-i get 3-5 P/H when wi-fi, Auto-Sync is on.
-i get 2-4 P/H on HSPA + Auto-Sync on.
-about 1-2 P/H or sometimes a straight line on Battery Stats when Idle, no data connection and/or auto-sync is on.
in other words, the glide can handle my needs in a whole day without completely draining it's battery.

Battery drain???

Is there a drain??

May I ask why you suspect a drain, like how long does it last and also what's wrong with the built-in bat-stat?
My biggest recommendation is to avoid DL'n every single app and keep it to a minimum.
Mine last roughly 2days with a screen time of 3-4h without charging (was away a weekend recently and took my chances and left the charger at home, used the camera alot incl. 4k shooting and alot of music videos playing and made all the way home with 1 percent )
Best phone in terms of battery I've come across yet.

on the stock rom and kernel?

Hello, what's your android version and firmware build number? I would like to use it because i'm on 4.4.4 build 14.4.A.0.108 and I'm experiencing fast battery drain.

Changing ROM will not help in most cases if you won't discover what is eating battery.
I am on the same above ROM and kernel and I don't complain.
Term 'fast' is not much precise, either.
BTW:
1.3%/h is pretty reasonable if phone was in use from time to time.
Base rule with BBS is to check batery over night, when it is not used at all.
Under those circumstances you should see 0.1-03%/h and that is completely fine.

As always - check that all automatic synchronizations are off.
google, pictures, facebook, whatsapp.
Hope you don't use WiFi all the time, nor you scan for available networks.
BetterBatteryStats is really helpful, read corresponging thread.

i dont think using wifi and auto sync will drain my battery from 60% to 6% in just a second. Anyway, i ordered a replacement battery from witrigs. Hope this fixes my problem. Ive tried factory resets and repair through pc companion. still no improvement. Turning stamina mode improves my battery. It no longer drops 50% in a second, just 10%. Still way too low compared to my excellent battery life with kitkat. Before lollipop, i charge my phone every 2 days with heavy use. Now, i need to charge it twice a day with moderate use.

If so - I'd come back to KK before replacing battery, if for no other reason then to prove LP is guilty.
BTW:
Long ago I decided not to upgrade to LP.
Looks like evey step ahead is in real life step back.
Everything is more complicated, wants more maintenance, yet works worse than old simple tools.

This with additional adblocker :angel:
And removed alot of bloatware and sony apps I don't need.

so... Did the 6 update fix the battery drain?

I haven't seen it since I got the update a few days ago... anyone else seen it since the update? *fingers crossed*

mines been on since 1630 yesterday, connected to phone and screen always on now at 58%

I can't break the habit of powering down when I put it on the charger and keeping it off until it's unplugged. Works everytime. I only had stock mm for a day then flashed alex6600s kernel.

In this mode and on table it drain about 0.5% by hour.

I know I'm probably jinxing myself but I'm finding the battery is *much* better in this build!

no battery drain so far
Since 4 days on MM....long way to go until we know for sure though...so far MM seems pretty stable...equal or improved over the previous one.

Quick update from M - 3rd day, 20% battery left. Thanks Sony

After update to MM I turned off gps, wifi and my watch not live more than day. It have about 5% power consumption per hour. What the problem is?

Havn't seen much change yet.
But even when the watch was om 5.1.1 it did good time. Two to four days between charging. Normal two days when using GPS for running every second day.
And so fare it behaves the same on 6.0.1.

No, it didn't. Not because it was 5.1.1's fault but it was app sync's fault.
I had only one battery drain on 6.0.1 - it was right after the very first setup. The same thing happened to me when I was setting up my watch the very first time while on 5.1.1.
On both versions, unpairing the watch, forgetting it in the app, resetting the watch and then, again, pairing it with the phone while plugged, letting it do its job during the sync process, not touching both the phone AND the watch for some time fixed the problem.
Battery life on 6.0.1 is very, very good. The watch lasts for about 3 days. Always On - ON, Gestures - ON, WiFi - ON... well, everything is on, even location.

exactly the same here, did the 6.0.1 update and battery down to 16% in less than 40 min.
Wiped everything, unpaired, did update again but now via PC companion, resetted everything again and now great battery life. 2x 20 min gps daily for bike ride and still 2 day battery life.

It drop to 10 after power ON the morning. When Power Off for the night it was at 46%
So no software issue (and never was software issue), just a deffective (deteriored) batt. I think there are faulty regulator charge circuit in SW3 and the battery overcharged. Just see how fast an SW3 can be charged, not normal charge process.
In general way, when a lithium batt drain faster after 50(40) % it mean batt is damaged.
I have normal drain from 50% to maybe 40%. Problem is after 40%.

So far I haven't suffered the random battery drain since the update.

Poor battery life after 8.1

Hello, I've had my xl2 for about 2 weeks ago and just got the 8.1 update 3 days ago.
I have a pretty strict morning routine when I wake up and unplug my phone pretty much the same time every morning and do the same things on it. Prior to 8.1, I'd lose about 3-4% every hour and now after 8.1 I lose minimum 10% per hour.
Anyone else experiencing this?
I am lazy to factory reset my phone and don't see how it can help since it was just a version update to oreo 8.0.

yeah.. i noticed the same issue as well.. cant be bothered to do a factory reset :/

Been experiencing the same. I did a factory reset and started completely fresh (no backup restore) yesterday.
It doesn't look promising.
Sent from my Pixel 2 XL using Tapatalk

Same issue here. I was spoiled for a few weeks being able to be on my phone all day and leave work with 60% remaining. Now, with similar usage, I'm between 35-40%. It's still sufficient, just noticeably worse compared to how it was prior to 8.1.

In a sense I am happy to read that others have the same experience because hopefully then Google notices and fixes this. How can we give this feedback?
I am able to still make it a day but now I have to be conscious about my usage and before I didn't have to worry at all.

I think it's Google Play Services 11.9.51
I installed 11.7.46 and it seemed to stop draining immediately, but it auto-updated an hour later and has continued to drain since.
Sent from my Pixel 2 XL using Tapatalk

I was planning on flashing 8.1 but after reading this maybe I should hold back on that. Afterall I'd only be missing out on AR stickers and a slightly improved camera software.

Can't say I've seen the same. At 50% I regularly get between 4-5 hrs SOT.

Mine isn't as stellar as others listed, but it's better than what I got on 8.0.
Of course, everyone's usage is different as are the many variables that each device deals with.
Comparing 8.0 to 8.1 using the same device, under similar usage and variables, is a good, practical measurement of better or worse battery life.
Comparing diff devices, under completely different variables (wifi, signal, usage, charging practices, etc.) is for the most part futile

Just updated this morning, but so far my battery seems ok. 5% used after 4.5 hours.
I noticed the 2 XL ate battery for a couple of weeks after new, then settled down and has had excellent battery use (rather lack thereof) after. I've also noted that after major system updates the battery use shoots up for a while then settles back down.

I think it is only now reporting more accurately, but overall it still loose .3% per hour when phone idle and 7 to 8% per SOT hour, still charging once every 2 to 3 days.

People who are experiencing poor battery: turn your WiFi off, reboot, don't reconnect to WiFi.
Spend some time then post your results.
Sent from my Pixel 2 XL using Tapatalk

I think the poor battery life in 8.1 is related to buggy charging system,the new machine learning in battery estimated is buggy,google need to fix it.

Hi Everyone, I think I may of found the culprit.
In developer options there is ""keep mobile data on on wifi" which I believe maybe was disabled for 8.0 and then enabled on 8.1
Just discovered this tonight, I also factory reset my phone, clear all Google play services memory and force stopped RCS service.
Will report back tomorrow.

Unfortunately, maybe a slight improvement where I lost 9% instead of 10-12% on the same usage.
Guess this badboy is going back and going to try the U11+.

I'm noticing the same thing.
I'm currently at 80% with 1hr 20 minutes SOT and 7hr 45 min off the charger. Prior to the 8.1 update, with similar usage I'd be at like 87%. At this rate I'll probably be getting like 7 hours SOT over like 20 hours which is still pretty good but not like the 9 hours SOT over 36 hours I got pre-8.1.

Battery Issue after update resolved
I resolved the battery issue by changing the Google Play Services app Open By Default value from 'open in this app' to 'ask every time' and now my battery is back to it full potential!
I have no idea how or why this setting was changed, but my battery was near worthless after the 8.1 update. Under normal usage, the battery would be depleted after only 4-5 hrs which is nothing compared to the normal battery life I usually get (>24 hrs - 36 hrs).
Change this setting:
Settings>Apps>All Apps>Google Play Services>Open By Default>Open supported links>Ask every time

Does anyone else use more than one Gmail account? I was using two and it seems like part of the problem is this. I removed an account and got 3 hours of sot on the 50% battery. Before that, I got 2h with 50%

For me it looks like turn wifi on automatically is the cause. Think it's in conjunction with the new play services. I did the WiFi off and reboot and everything was fine until that started kicking in

Few weeks later and still getting a piece of **** battery life. This is so lame.
