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

[Q] Phone always charging

Like the title says...
I pull my phone off the charger at 8AM. By 9AM it still shows 100% and still has the charging icon.
Finally at 10AM it drops to ~67%
It started a few days ago... Previously the charging icon would flash on and off every few minutes...
Here's a pic of the battery screen:

Is it a bad battery? Maybe the phone is going?
Software issue?

@orb360
Give you're battery the spin test... as for the charging icon staying on... could be a dirty port or a connector touching/bent inside the port itself.. strange that it stops.. I'm not sure..
As for the bad reading and then a huge drop... have you recently changed batteries or flashed a rom... I'm kinda at a loss... I once had my battery read off by about 20 percent and I had to wipe my battery stats in recovery to get it to read right , but that was after I replaced my old battery with a bigger one..
Just my thoughts...

It won't spin much... I had a previous battery about 1.5 months ago inflate and had to replace it... ( It actually popped the back off the phone )
I picked this one up at a Sprint store around that time.
Is there a way to wipe battery stats without a custom recovery flashed? I'm running stock 4.1.2
It's a work phone so I'm not really supposed to be flashing custom stuff to it.

Well, You'll have to root your device to wipe battery stats

You most likely need a new battery.
Wiping battery stats... Let's just say that if snopes.com were to cover Android, this would have to be one of their first articles. There is a ton of myths about the unicorn-like magic that can result from wiping battery stats. The truth is, the contents of the batterystats bin file basically tell a part of Sec Settings some information in order to make estimates for displaying numbers in your battery stats (literally, in Settings) - details like screen on for two hours, used 40% of battery... wiping battery stats erases those few lines of information, nothing more. It doesn't somehow alter anything inside a battery, or anything else.</soapbox>
If you want to clear battery stats as it were, no harm in giving it a shot, right? It is very easy to do. Every time you charge and then unplug near a full charge you have reset battery stats. That's why it will all say "0" if you look real quick at the battery stats in your settings - poof, battery stats were reset.
You should get a new battery though. Get work to buy it. Cheers.
[Reference one Google developer's article about "wiping battery stats" here: https://plus.google.com/105051985738280261832/posts/FV3LVtdVxPT]
Edit: Wondering how you'd kill batteries so fast. Do you use your phone a lot while it's plugged in by any chance? Like, watch hours of netflix while plugged in? Just trying to think of how you might be cooking things in there perhaps, so... next battery will last longer than six weeks.

Well...
I'll see if a new battery fixes things... At only a month and a half old maybe the Sprint store will replace it no questions... hopefully...
If I turn off the phone and pull the battery...
If all I do is stick the battery in, it acts like it's charging... The "phone is off" battery charging screen comes on for a few seconds.. Then it shuts off and comes back on. Repeatedly.
So it can't be a software thing if the phone's not even turned on right?

That part is correct. Bad charging port can certainly do that, but the erratic charge status reported as in your previous posts wouldn't be because of a bad charging port, so I do not think your problem is that part of the hardware... It sounds like "classic" bad battery. I would certainly try to argue/plea/demand a replacement battery from Sprint given the short life it had. I don't know off hand their warranty on that sort of purchase, but I'd bring my I-mean-business to the store for sure. I do know they have some discretion at the store level. I'd go in anyway - show them what it's doing, bring the receipt from the battery you just bought, and hopefully get a fix. If there's some other miscellaneous hardware problem creating these problems, it's no longer within my knowledge sphere, lol. Good luck. :good:

I got a different battery to test with and the issues persist
(The charging while disconnected and unable to power on without being connected to a power source)
I've read cleaning the charging port with alcohol might help...
If that doesn't work I'm just going to send it back for a refurb.

Worse battery life with KK

Worst fears realised.
The Kit Kat update has delivered drastically worse battery life.
Could often work with 10% per 45 min - 1 hr screen time before on WIFI, that has now gone out of the window.
1 hr 44 min screen time with 68% left now.
That is quite a bit worse I would say.
Anyone else feel the same?
I would rollback, but the camera improvements are just so much better.

I had about 5 hr screen time and almost 2 days of usage. I am using stamina and greenify though since I don't need emails and notifications pushed, I just manually refresh it.

Nope, I just managed 7.5 hours OST on my last charge on WiFi without Stamina Mode, so quite a bit better for me than JB where 5/6 was more usual. Standby power is also noticeably better, averaging ~0.4%/h.
Sadly the KitKat changes make most battery stat apps useless without root now, or I'd suggest you run one to see what's up on your end.

Cant find anything that stands out. Going to drain and do a charge from fresh.

Did anyone try to calibrate the battery after flashing?
Calibrating battery gives exact battery reading.

There is no real calibration in android and for everybody pls alow 3-4 full charges before reporting your battery life on kitkat(same when flashing new kernel)

same here.
Done full drain but no change. moreover the phone gets heated quickly..

This is obviously a sign of some rogue process running intensively (compare performance after booting in safe mode to confirm). You should be able to figure out pretty easily which it is from the basic battery stats page, sadly no partial wakeleock listings anymore on non-rooted phones though.

I didn't installed any apps as I bought phone day before yesterday Then the possibility is bug in Sony's new firmware.

How to boot into safe mode?? sorry I am new here and this is my first android ph )
I have done factory reset>>installed 4.4.2 via PC companion>>full factory reset incl internal storage.. heating problem is somewhat solved.
But it gets heated up when connected to charger..which on JB doesn't happened!! strange..
Draining seems to be normal but takes too much time to charge..

I got a great battery life on kitkat.

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.

Hi guys,
I have a problem with... When battery drops down to 15, my phone turns off, and 46 six aps are being optimized. I'm not alone with this problem, my friend with HTC... has the same. Any solutions?
And now "com.google.process.gapps has been stopped and i must do hard reset.

The battery meter isn't that accurate, its just an estimation based on the battery voltage versus how you use your phone (and the resulting "typical" battery drain). You shouldn't expect it to be accurate to the being within the 1-2 (or even 5) percent range. Shutting off at 4 to 11% is not unusual, and not surprising.
You shouldn't be draining your battery down that low on a regular basis. Its bad for long term battery life. Good rule of thumb for Li ion batteries is short and frequent charge cycles.
However, optimizing apps and/or google process stopped after a shutdown (due to low battery) is not normal. That's a different matter.

I have this problem, plus some of my settings get reset such as my wallpaper, ringtone, notification tone, boomsound (off to on), screen timeout, screen brightness, whatsapp (keeps asking me to chose my backup options and no messages come through until then). This has never happened before and I'm not sure why it's only happening now. I'm not purposely trying to drain the battery or anything, it's just that sometimes on the road I am unable to charge it and it'll just die out midway when previously, that extra 15% could've lasted me for another 30 minutes, just enough for me to reach my destination.

The same problem.. But the bigger problem for me, it's reseting my settings..

It is a terrible problem , I return to KitKat and my battery reaches 1% , and so normal ... I'll make a test with lollipop .

Yes, same problem! So glad someone made a thread for it. It's frustrating and happens literally every time.
Experienced on both the stock and a custom rom. Any one knows any fixes? Is it because of the 'battery life reduces over time' thing? My phone is 2 years old now

That seems to be a problem with all htc ones (m7, m8, m9) as they get older, dont worry its normal :laugh:

ive been experiencing this for a while, clear dalvik cache and let android do the whole rebuilding thing at the start and you should be fine...as for the battery fix ive just learnt to live with it, 15% is the new 2%!!!

I'm on this problem since a lot of time, as i was one of the first in the community to report it.
Seems like an end-of-life issue for one m8 and htc one phones line.
In my case i had a camera and charge board issue too, so in rma htc changed them, and now the phone is charging and quick-charging like it must have to. But i have to be careful when near 15% of battery because using camera, flashlight or others power-expensive features instantly turns the phone off, causing a database mismatch on the next boot (for marshmallow) and consequently the loss of data.
If the instant-poweroff occurs during boot, there is a massive loss of data and a lot of force closes on the next boot.
Nothing to do here i think, sadly.

In kitkat and lollipop battery reach at 1% ...

I have a fix for this as it happened to me and I tried a battery calibration app from the app store... I thought what your thinking now but after finding bad sectors and "repairing" it did actually work

solve the problem of battery and loss of settings , change the battery of my htc, now everything is fine , 3 days that the battery is discharged properly , I hope this information will help someone.

thats kinda "cool" to see many people have same problem as i do. atleast it wont run u crazy as before
1. sometimes phone dies when battery is 15%, and sometimes it dies when around 4% 2% or even 1%
2.resetting settings after phone dies!
so is the solution, to change battery? any better way that doesnt need to spend money?

Yes I've done this a couple of weeks back. The replacement is actually less hard as it seems.
But finding an original replacement battery seems to be pretty hard - Even though the replacement I bought is HTC branded and looks genuine, I feel like it's actually draining a little faster than my old original. 12€ Ebay had too good to be true.
However the instant-shutoffs are now a thing of the past along with the database corruption, so I'm going to have to live with a little less battery life.
Or does anyone know of a provider for genuine batteries?
