Before I create a JIRA ticket for what I believe could be a bug I wanted to see if anyone else had experienced similar issues using PA on a Nexus 4. Ever since I flashed this custom ROM (and a subsequent OTA) the battery meter is inaccurate or not updating regularly. It will sit on a given percentage for a few hours and not move until I reboot the phone and you'll notice the new reading is substantially lower 5-10% depending on how long since reboot. I have since charged the phone to full and tried deleting the battery stats file using TWRP and also using the battery calibration app (which basically does the same thing) and it helped accuracy for the full discharge but noticed it died half and hour from when I last observed 14% so I think the voltage in the battery was less then what the battery indicator thought and it died. If I don't recalibrate after every full charge the meter is inaccurate again. This never happened on stock Android.
The closest logged bug I can see is AOSPA-536 over at paranoidandroid dot atlassian dot net

I've gotten my seidio extended battery and have never really tested it to its limits. I would like to have it functioning optimally. I have the app "Battery Monitor" installed which can calculate the percentage left via the voltage as opposed to the stock battery indicator. I am currently showing 57% via the voltage monitor and 35% via the stock monitor. I have found that my battery can drop to ~1% (according to the stock indicator) however the voltage indicator would be at something like ~30%...my phone would turn itself off at that point in time and I would not be able to take advantage of the reported battery....I have followed directions from: droidxforums.com/forum/droid-x-general-discussion/18216-disable-low-battery-warning.html...I bootstrapped and reset the battery...but nothing. I was wondering if anyone has had any experience in this or could help me out.
Thank you.
I think if you go into the screen where you clear the Dalvik Cache in the recovery menu there's a battery settings function. If i've read some of these posts correctly, that calibrates the phone to the battery. basically re-adjusts the 0-100 range on the phone.
You need to do this when the battery is fully charged.
Draining your battery all the way down will destroy your batteries capability of holding a charge in the future.
Your phone is suppose to only charge to ~90% and cut off at ~10%.
Ultimately this means you are only using 80% of your battery, but it's how Li-Ion batteries works.
If you truly drain it all the way down you ruin the battery.
There are some things you can do to recalibrate the software that determines the charge level of the battery though, like the above post suggests.
I don't know if you're running a custom ROM, but if you are or aren't you should definitely check into changing your phones Kernal to Chad's or IncrediKernals. They drastically improve battery life.
For me, it gave massive improvements for 'screen off' (1% depletion every 1 hour) and significant improvements when using the phone.
Of course I'm using the HTC extended battery, but that was much better than the 3-5% per hour I got before.
hello,
please tell me what's wrong with my xda iis. when the power below 75% and i activated wifi/camera/any apps, oftenly it turn off by itself. also, it often signal loss or cannot make/receive calls. thanxs
Has anyone experienced sudden rise of battery drain that is not related to firmware? I am facing issue with 9 months old battery, usually re-charged slightly with rare full cycles, that shows 4-5% drop per hour in standby/screen-off mode (all connectivity off). I have tried couple different clean ROMs installations without changes to this effect (Runnymede AIO v4.0, then v6.5 and less resource consuming Cyanogenmod 7.1 too). I tried to calibrate battery (at least in three different ways, with wiping battery stats etc) with no success. In desperation I did full cycle keeping device turned off for one night with charger plugged in, no results either. Battery starts at 100% and constantly goes down somewhere to 5-10% when it forces device to shut down.
I am curious why is that happening, especially that 3 months ago I could run for 2-3 days using phone from time to time, now on screen-off it cannot last more than one day? BTW I did not change my habits for last 2 months, I have not kept battery in freezing cold or kitchen oven when charging etc I would expect that Li-ion battery capacity degradation is constant and rather linear process.
Now I can look for someone that borrow me second battery for comparison, or I need to buy a new one (something like cheap Andida 1800mAh one).
Any other suggestions except for recycling the phone?
EDIT: Now I am completely astonished... saying "connectivity off" I meant everything except for regular cellular network. After switching to "airplane mode" my currently used runnymede AIO v4.0 drained battery only 1% per hour! First thought was "roaming problems" (because I came from Europe to Abu Dhabi / UAE in business last week) and I googled some complains on battery drains when traveling. I wish that would be a problem but I added another variable to the equation -- I installed MIUI ROM which gave me 1-2% per hour with GSM switched on. Radio is untouched when reflashing ROM, MIUI is close to Cyanogenmod (same kernels, also lightweights) but the latter was also sucking down on 5% level... so what is it? damn this pocket computers
cheers,
-andy.
To help others struggling with battery issues - mine is solved. It was roaming problem specific to United Arab Emirates !!! After returning home everything is fine, less than 1% per hour. Also roaming in Germany did not cause drain even though signal strength was on similar level as in UAE. Thread closed.

My defy battery has been playing up every cycle now. Tried using battery calibration. Been trying both Quark and Eppy builds. Now on the latest Defy Quark build. Got a green lens defy. Haven't a clue what is wrong.
Nothing explains the massive drops. It always happens around these points every cycle.
Any solutions?
I'm having the same problem with my green lens Defy. When battery is between 40-30% it suddenly drops about a 10-15%.
I haven't been able to found a solution to the problem yet (I have yet to try battery fix, but i think only red lense Defy's need it).
At first i thought it was a battery calibration problem, but after wiping stats everything remained the same way as before (now I know that wiping those stats does absolutely nothing to the battery).
I hope it's a software related problem and not my battery dying.
I think it is ics-based. I experienced after calibration (Hard-battery-script) two drops every circle, 55-49% and 29/26-19%.
Cheers for the information guys. It's good to know I'm not alone. I couldn't find anything on it!
The only things I can relate is that it is on green lens defy's. Maybe...
Is there no solutions for you guys? I found that calibration did nothing too.
How long have you guys had the problem for?
I first found this bug after flashing CM7.2 RC1. After seen it twice, I decided to wipe battery stats but it didn't work.
After that, I flashed CM9 (epsylon build) and was behaving the same way as CM7.
I couldn't tell if this bug was happening on stock Froyo, since it didn't have any kind of battery graph and I wasn't noticing anything suspicious to install a more detailed battery app.
Easy,guys.
Although its battery has these two gaps,
it remains on power which means it lasts longer at every 1% than before when there's no gaps.
I have kept a record when I just purchased defy.
That time is 2.4 hours per 1%(full discharge) mobile(2G) standby,
and now I have these gaps (14% total)as you mentioned,but it lasts 2.8 hours per 1% at first 20% then 2.7-2.5 hours per 1% to the last.
Actually,it is the same amount and this is under 1 year use!
is it my phone or battery
im using cm9.
my original defy suddenly died (got swollen) so i bought 2 new battery from two diff. supplier. (SNn5885A). it charges ok for the first time but i noticed on the first battery when it got drained. it wont charge anymore. it got stuck on 4%. the other battery, not wanting to fully drained it, turned it off at around 50%. but when i tried to turn it on this morning, it got the same thing as the other battery.
the question is, is it my phone f* the battery or they are just no good? how will i know?
thanks
I noticed that my phone drains/charges at faster rates at some battery percentages, especially 90+ and 10- .
It also sometimes skip percentages or increase. i tried calibrating many times . is this normal or i missed something
im using ARHD latest release
Sort of noticed this, seems to be less when i do a full charge cycle (and battery stats - people so it doesn't work, but i still do it)
I've noticed the last 5% or so seems to last at least 3 times as long as any other 5% of the battery... But that's quite normal on any battery powered device, they seem to go one way or the other (super fast or slow) with the last few percent - I guess it's all part of the magic that is battery capacity guestimation.
That is the normal behavior of any cell phone battery. I cant remember the technical reasons for it, but if you are interested read about C-Rate and its implication on battery charge/discharge times.
Here is a good resource
Hi everyone, I am running HTC 10 marshmallow stock rom (My country doesnt have nougat update yet) and I faced some problem with the battery recently. I went to travel in iceland for about 2 days, and after i came back I realised a rapid drain in the battery power even during idle.
Below are a few tests that I carried out,
1. I charged my phone to full and carried out the default battery test by typing *#*#3424#*#*. The results was 6% of battery drain with screen on for 1 hour at maximum brightness in airplane mode. From the htc 10 customer service team, they said this shows that the battery wasnt faulty ( The battery is faulty if battery % drop below 70% in an hour).
2. Then i switch to safe mode to check if it was the background apps that causes the problem, even worst, the battery over night in extreme power saving mode was dropped by about 40%. I factory reset the phone.
3. The next day I do the same thing as (2), but this time with airplane mode, the battery drained over night still about 40%.
The battery usage from GSAM apps shows nothing unusual going on in the background at night.
I have to charge my phone at least twice, once before i sleep and once after i woke up, i sleep average of 7 hours a day.
My question is, since its not battery issue, after i factory reset the phone this problem shouldnt persist, can somebody explain to me before i decide whether to send in for repair? Sorry if the thread was repeated.
Attachments below shows the batter drained
This is the battery reduction graph during safe mode tests
There must be a rouge app running somewhere.
Your phone doesn't seem to be "sleeping" at all.
It's whatever is causing the extremely high (100%) awake time, that is causing your battery to drain so quick.
Would be helpful if you could send a screenshot of the main stats page on gsam. Example below: (from my M9)
