[SOLVED][Q] Battery issues?

Wondering if anyone else has had any battery issues? I went to sleep last night with about 85% or more battery, and 5.5 hours later my phone was dead....when i plugged it in for like 5 minutes to call my work and tell them i was going to be late...when i got to work my phone said 45% phone idle and 45% cell standby for battery use

none here - took phone off charger about midnight, this morning after alarm rang for the full 10 minutes, it still showed 100%
i've been watching it and am really impressed with battery life - is it possible you've got a program running in the background? - i had Startup Auditor to stop apps in the background but had that from before, on my Vibrant
on the vibrant,running a predominantly black wallpaper, screen brightness at 13%, putting phone in "airplane mode" when i sleep, keeping GPS off, data sync off etc, it'd be down to 17-22% at end of day before going back on charger
this G2, running live wallpaper (thunderstorm), no efficiency moves (ie GPS off, etc), screen brightness at 50%, phone still had 34% last night before going back on the charger - and the battery has not "conditioned" - i noticed on the past 2 phones batteries life got better after the first few weeks of use.

Nothing different than my nexus...and i was thinking maybe it was a game but that should have been killed automatically and i dont think it would say phone standby and cell idle if it was an app would it?

tonite you might try putting the phone in airplane mode when you go to bed, and turn off GPS
see what happens to battery drain overnite - if it diminishes then i'd look at what apps you've installed. there was an article on engadget not too long ago that some researchers had analyzed the 358 most popular apps, and found 30 were reporting data to their "mothership" that had not declared it or asked for permission to report data.
hope that helps

well another weird thing is, that when i bought the phone and brought it home, usually it comes with half battery and thats what it showed but i had to charge it quick with no apps really installed on it yet...Im charging now and will test to see what happens with battery...i just removed off alot of my apps.... to see whats up

I'm getting about 10 hours with regular usage though I wish I knew why Photobucket keeps starting everytime i kill it.

I hope you guys charged the phone fully before you used it first. That can play a big role in battery life.
I got my phone yesterday and haven't done any calibrations yet. I've been playing with it like you normally would if you buy a new smartphone. I took it off the charger around 9pm last night and at 7:32am right now I have about 60% left. So roughly 10.5 hours later and I've only lost about 40%. I'm very impressed by that. My vibrant would have been dead by now, it rarely lasts through the night if its not on the charger.

What's your time with out signal, sounds like the 50% bug to me, google the airplane mode fix, if not you might want to look into a new radio, and you should allways recal your battery after you flash

[Q] Inc consumes battery when turned off

tldr: My Incredible drains battery when turned off :-/
I have an HTC Droid Incredible that I use for testing my developed apps, and for playing around with people's roms, and I have found an odd issue with it. I can charge up the battery and use it for hours and hours and it consumes what I would consider a normal amount of charge, but when I turn it off, it still consumes battery charge. I'll charge it to 100% and disconnect the charger, hold the power button and select Power Off, and when I turn it on the next day the battery is very depleted. Yesterday I did this, and this morning about 16 hours later, I turned it on to see a 23% charge. If I leave it for more than a couple days, it won't even turn on at all and I have to charge it again before I can do anything with it.
I've tested this over the past few weeks with two separate batteries (one used, one brand new), and the same thing happens with each battery. It's definitely the phone and not the battery, because I have taken the batteries out completely, waited a few days, and they stay near 100% charge.
Some history on this phone:
I got this phone from a friend in a semi-working state. I couldn't root, s-off, or really do anything with it, so I did a factory reset, messed with it for a while, and finally decided to follow the steps in this thread to "unlock,downgrade,and achieve s-off with htcDev". This has allowed me to mess with roms, etc, so I have installed a couple, and now have "inc-eng 4.1.1 RC2" installed from this thread, and this kernel: "[email protected] #64 Mon Sep 3 18:55:57 EDT 2012"
The issue at hand however was happening before I even had it in my hands, as my friend described the same thing happening to him (he did not mess with rooting, roms, etc).

Thanks, but I did test that, with both of the batteries I have. I've left them for multiple days out of the phone, and when put back in they show 95-100%.

Maybe it's not turning off all the way.
Here's another test: turn it off, remove the battery for about a minute, then put the battery back in. Turn it on the next day and look at the battery level.
Might be a ROM issue. What ROMs have you tried this with? Have you tried stock sense and CM7?

Will do, I'll post tomorrow with my results.

If you have fastboot enabled then the phone is never really off. Try charging it then pull the battery, and put it back in the phone but leave it off. Turn it on latter and see if there was any battery loss. Fastboot is like hibernation. Its possible that some app is misbehaving and trying to sync or something while its hibernating, draining the battery.

Alrighty so yesterday I charged both batteries to 100%.
Battery A stayed out of the phone on my desk.
Battery B I removed from the phone, waited 10 seconds, and put back in the phone (I did not turn it on).
This morning, the phone (with Battery B in it) would not turn on until I charged it for a few minutes, and displayed 0% charge when it finally let me turn it on with the charger connected.
This is so weird...
Also, the rom I'm using doesn't have a fastboot option that I can find.

Okay so Battery A I put into the phone at 4pm yesterday, turned it on and found it had a 73% charge. I then turned the phone off, waited a few minutes, put the battery in and left it on my desk. This morning 12 hours later, I turned it on and it has a 25% charge.
I'm so confused... if I don't turn the phone on, how are the batteries discharging? Both batteries keep their charge when left out of the phone for a prolonged period, but discharge when in a phone that hasn't been turned on. Bah! >_<

Mabey there is a short in your phone somewhere. Does the battery last like normal when the phone is on, or does it also die quickly?

I'll have to test this when i get home, but I beleieve the battery discharges at a normal rate when the phone is on.
(this is not my normal phone, just one I use for testing apps, etc. so I don't use it on a regular basis)
I'll charge one of the batteries to 100% and leave it on overnight, and post my results.

Mine drains when all the way off 2 but not that bad... I think it may be the MotherBoard keeping power to the Nand memory so it dosen't relock and keeping power to the CPU so it can be quicker on bootup

I'm assuming there's no way to stop it from doing this?
It's not a huge deal, as this is a test phone I use for development, but I may be eventually selling my test phones, so I try to keep them in good working order, or get them to a decent refurbished point Plus this is a weird enough phenomenon that I figured it deserved discussion.

S3 Battery Drain

Hi, I had my galaxy S3 from Rogers for almost 1 year and the battery drains like crazy!! When I first got the phone the battery life was ok. It lasted 1 full day (with the settings auto brightness, wifi usually on [when not in wifi area, using LTE], vibrate only, power saving on and snyc on. I turned off gps, bluetooth, location services, and motion). About 6 months ago I dropped the phone in water :S and I got it repaired. The phone battery life was still about 1 full day (with the same setting as above except when I'm not in a wifi area I use 4G to save battery life). After that every month the battery life seems to get worse from 1 full day to about half a day :S. After doing alittle research (this was around May/June) I found out Facebook was killing my battery so I stop using it on my phone then my battery got better (to about 3/4 of a day). But after that in July and August the battery life got really really bad, it will probably only last 5-6hrs. I honestly don't know what is wrong with it now. Is the water damage the problem with my battery drainage?
I'm running 4.1.2, never rooted and I'm running Nova launcher too.

I leave mine on auto brightness too, I still get around 24 hours on a charge, and between 5 and 6 hours of screen on time. My phone is only about 3½ months old though... Could be the battery??

I got my s3 in dec. It worled fine till now.
I am facing the same drain problem. No wakelocks active.... checked better battery stats. Phone is going in deep sleep.
My real problem is
Whenever I plug my charger and start watching a video song or movie. Charhe gets real slow. If I dont use my cell while charging, it charges fine.... dont know why is this so.

Is it the original charger that came with the phone? And are u charging it from the wall or pc??

Ya I am using the original charger and original cable.. using ac supply, with plugged in wall...
The thing is if I reset my device ( which I have done 2-3 times) and after that, watching video/playing games/ internet surfing etc. With the charger plugged in, works fine... I mean it charges my phone battery fine. Battery is new. Checked its condition with battery monitor pro... it states its good.
But after a couple of months after resetting, I face the problem of slow charging, with my phone in use while plugged in... did a lot of search but didnt help out. Cleared dalvik and other cache.... nothing seems to be working.

[Q] Battery drop after reboot?

I've been experiencing huge battery drops (from 10% up to 20%) after I reboot my phone. Is this a KitKat issue or is it my battery?
In the morning from 99% (after checking a few messages in the morning), I rebooted and I dropped 11% to 88%.
I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one. :good:

I didnt found it on reboots, but i have this problem when i enter recovery. 20 minutes in recovery - i dont hace 20% of battery.

Hmmm that's strange.
I've noticed it usually drops more when I leave my headphones in.

full loaded ACE 2.
reboot cost u 5%
first 10 % gone in a few minutes for heavy users and in a few hours when deepsleep !!
what i wanna say.
the first 10 % gone in a few.
after that normal drain.

I often get this, although not as bad. I usually lose 2-5% on a reboot, sometimes up to 10%. The other week I charged it to 100% when it was off, turned it on and had 92%.

so is this actually a problem or is it normal for everyone?. Mine looses 5-8% in the first couple of minutes after I unplug the charger..

It's normal.

Its normal. I usually lose the first 5% of a full charge in a couple of minutes. After it gets to 95%, battery charge will drain normally depending on usage.

ok then, thanks...I just thought that this didn;t happen when I was on GB, but it doesn;t matter anyway..

If I reboot once, I will lose between 5 - 10% battery. However, if I reboot straight after the first reboot, I will lose between 0 - 2% battery. I've never really understood this.

Phone need more energy for reboot, that causing the drain. Mine usually drop 2-5%. After recharge battery alsi drop to 95-92% fast. Thats normal

Battery Charging Issue
Is this normal?
When I charge my battery whether it be from mains or USB computer it charges ok, but as soon as it gets to 100% it still says charging for a little time and doesn't report the unplug charger message right away.
With the Jellybean 4.1.2 system I don't get the alert tone when the battery reaches FULL, therefore I have a feeling that when it still says charging even though it's showing 100% that it's actually decreasing power at that point, any help please?
I have tried other batteries, and one in particular goes from 90% right up to 100% and seems to miss that last 10 percent, so I don't use that one now.
I have the most current firmware installed.

Buy a new one

when it says 100%, you still have to wait for a few minutes before it displays the green "full" icon in the upper left corner and asks you to disconnect the charger.
However, the first 5-8% always drains REALLY fast and not proportionally to the rest of the battery drain...

I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one.

what about the initial drain? does the first 10% still drop fast or has this changed too with the new battery?

I just wish that JellyBean 4.1.2 would give an alert sound when the battery has reached it's full limit like Gingerbread used to do.
Who would be the best place to ask them to do this on their next update?

But I think that it does..a very short one indeed, but it does, along with the screen lighting up briefly..

Official fix for battery problems

This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.
Do this every month or so to keep power system healthy--even if everything seems fine. Also, don't leave phone on charger overnight for best long term battery life (according to HTC tech support: "The first thing they tell us." This is true even though charging is supposed to turn off when battery is at 100%)
NOTE: Another potential fix for battery/charging abnormalities if this procedure fails (esp. after an OTA update when corrupted files can remain stuck in device cache partition)--clear cache partition using this method: http://forums.androidcentral.com/verizon-htc-one/315416-how-clear-cache-partition-stock-recovery-un-rooted-phone.html

Check your battery history in settings. If the 3. bar, in the middle, is always there (it's probably called "in usage", I'm on a different language so i don't know), then some app is always on and it's draining your battery. I haven't discovered which app is that yet, but I'll install battery monitor app to discover it.
When it's like that, i lose 1% per hour on standby, which is a lot, because normally during the whole i lose about 1-2%. So I kill all apps with Clean Master and then the 3. bar isn't present anymore when my phone is on standby.

And why not just let the battery die. I mean let the phone turn off and then charge it to 100%. This is the general way to calibrate the battery.

Now you're talking crazy. I'm fairly sure the same advice for NiCd and NiMH still applies, even though they're completely different technology and haven't been used in phones 15 Years.
I personally use witchcraft to keep my batteries in working order.

Lipo batteries are way different than NiCd and NiMh and their chemistry is unstable to say the least. But by all means be crazy yourself and drain your battery to 0% if you feel the need.

I think you missed my sarcasm, I agree with you.
You can't drain the battery to 0 without going out of your way as the electronics in the battery protects it, but yeah, as soon as your phone switches off, it's time to add some charge, if not way, way before. I don't actually believe in this calibration thing people speak of.

I ran my M8 completely dry once on purpose a couple of days after purchase. I always do this at least once with every phone sometime in its lifespan.
When doing so, the phone sat at 1% charge for over an hour while I had the screen on at maximum brightness all the time and streaming music with Spotify.
Needless to say it was needed for my phone.

While using the phone, battery doesn't drain as fast.. When its in standby, somehow it drains faster..very strange

has this process worked for you for every device you've owned? I'm getting horrible standby drain on my m8. Wifi on, location, autosync, bluetooth, nfc all disabled. in a span on 9 hours I lost 10% close to 11. the only thing I can think of is I haven't greenified anything, but I shouldn't have to..
and like another user said I seem to get better battery life when it is in use then when it is in deep sleep

1% battery drain per hour is about normal. If you don't want out to drain turn it off

it shouldn't be if you disable everything.

Tried this. It did seem to work for me. I was skeptical, but I definitely feel like it fixed the erratic battery behavior I was seeing.

According to HTC tech support, the battery in the One has a chip that tracks charging/discharging. This chip's memory is cleared via the specific steps I outlined (both volume keys and power button cycling). It's important to do this process while the phone is plugged into the HTC charger that came with the phone--not an aftermarket charger. Apparently, the charger chip is also affected by this reset.
I performed this reset procedure a few times, cleared the device cache, did a data reset, and also installed the new OTA. None of these steps completely corrected my erratic battery behavior. I'm sending the phone back to HTC for a replacement. In researching this, it appears that after the prior KitKat OTA several weeks ago, a number of folks have complained of the same power problems on various Android boards and I believe HTC is aware of the problem.

Its an electronic device that is running. Should it be magic and use no power. At 1% per hour thats 100 hours of standbye time which is not bad. I agree you should be maybe a little less with all location services, data, 3g, wifi, bt all disabled but remember. Its on and using power, it has to use something.

Hi there, i have a problem with my battery, when the percentage is 15% the phone starts discharging very quickly, like dies in 1 minute. From full charge to 15% discharge seems legit. In your opinion can be an hardware or software problem.

Hy, my phone dies at about 15-20% but when I plug it in the charger it says 20% and charging.... I turn it on and the same thing happen...
ANy help on how to fix this problem?
Thank you

Did you try the procedure described in the first post, for which this thread is about?

Question,
I was trying to follow the procedure for battery reset. I did this in the past when I got the phone. Since then I I unlocked bootloader, rooted and S-Off. Now when I try the volume up/down + power, after a few cycles of the logo screen it goes to bootloader screen. Cant' get it to go the 2 minutes mentioned. Any ideas?

I tried the procedure and the phone kept restarting like every 10 seconds through the process.
There is no Fast Boot option on Marshmallow, so that's out. I'm leaving the phone to charge overnight.
In my case I'm afraid there's a certain App that's creating the drain because the battery was showing 20%, then 50% while unplugged and then it died 15 minutes later while I was reading the newsfeed.
I will edit this post with the results in a couple of days.
Updated: Ok sooo, the first charge after calibration lasted about 12 hours with moderate/heavy use.
Now I recharged again and I don't understand. It has stayed at 100% for more than 15 hours!
I have Amplify and Power Saver settings for vibration and dim screen and that's it. I don't get it.
As a final note, HTC recommends doing this chickenchocking thing every month! I felt like I was killing the poor thing trying to boot. But anyway, that's my results so far. Oh, I'm using Gsam for readings.
