Strange Battery issues - General Questions and Answers

Am having 2 issues with my battery. I have an Anker 7200 mah extended battery currently. {I have also noticed these issues with previous batteries I have used}. I charge my battery to 100% and then when I check the battery screen in settings several hours later, it will show for example that I have been on battery for 4 hrs when in fact it has been 5 or 6 hours. The second problem I am seeing is on the bottom portion of the battery screen it will only show % for screen, device idle, cell standby and sometimes, voice calls. It will not show usage % for other things like email, tapatalk, games, etc. Pls see attached for example. In the screenshot it shows I have been on battery for 2 days and 0 hrs when it have been at least 2 days and 5 hrs. And bottom part of screen only shows screen, device idle, cell standby and voice calls percentages. I've let my battery drain until it was almost completely dead and I've calibrated my battery but still having same problems.
Was wondering if anyone else has come across these issues and what was done to fix?
Thanks!

Again with the Battery

Is anyone that is having battery issues running Adao Task Manager and Battery Status Pro?
I just factory reset my phone and I got 24hours of batter life. About 8 standby but a good deal of texting, web, some calls and some you tube.
I installed Task Manager and Batter Status Pro last night and my battery this morning went down 15% in about 1hr.
I uninstalled these today and will post again but has anyone else seen big battery drain from these apps or does anyone that is having issues running something similar?
I have been playing with the battery for about a week now.
For me this phone runs pretty good during stand-by. I would have about 2-3% drop for a whole night (7 to 8 hrs), with Google (push), Twitter and weather syncing.
The problem is when you use it, it drops like crazy. When I read news or surf the web, it would drop 1% every 1 or 2 min.
This morning I read an ebook, with black background for about 30 min, it dropped about 3%.
So basically i think the screen, data connection, and non-black background are the ones that kill the battery.
Yea, I agree, the S-AMOLED screen in this thing is an energy hog. OLED's are supposed to be more energy efficient than typical LCD's but I'm just not seeing it. Whenever I look at battery usage stats it shows the display at 70-75% of battery usage. Thats ridiculous. I have until the 18th, but I'm quickly leaning towards returning this and just getting an iphone4. This phone is becoming more and more disappointing the longer I have it.
This morning I have been uplugged 4.75hrs and used 16% no battery monitor and no app killer. Basically done the same things I did yesterday. Some Bebbled,texting, email, phone calls .
I will update tomorrow with total hours battery life for today. Would be happy if I can replicate the 24hours I got the day before installing those apps.
I got like 45 hours of battery with moderate usage during the two days. Seems fine to me, I occasionally used system panel to monitor if anything was using high and constant CPU
This is pretty typical of a 1ghz phone My nexus would last a day of heavy usage, 2 days if i use it lightly. We need to wait for undervolted kernels to be developed xD
Also, it really helps if you disable 3G when you don't use it. This allows me to get 3-4 days of light usage out of my nexus. I haven't played with the Captivate long enough to know how much of a difference this makes on this phone though
when you guys refer to "stand by", what exactly do you mean? Just screen off/phone idle? The battery usage on my phone when I use it seems to be OK even if not amazing, but it continues to sap life from the battery when I'm using it at an alarming rate.
Standby is when the phone is idle/screen off/locked.
The display is definitely power hungry. Using the Power Control widget that comes installed definitely has helped with battery life. It will let you toggle WiFi, BT, GPS, Data Sync, and Brightness (at 3 levels). When I'm not using anyone of those, I turn it off. When I'm indoors, I'll set the brightness to the lowest level. I'm usually at my desk when I'm streaming music, so I'll have it plugged in.

Actually they are more energy efficient on black screens, But screens with a lot of white in them suck battery bad.

This is true the white screens burn the battery etc. I just wanted to let everyone know what I did to make my battery last more that 24hrs.
First, read the Wiki guide and apply some of the battery saving tips.
Second, UNINSTALL a program called "gReader" created by noinnion. This program is a huge battery hog! At least it was for me.
Hope this helps.
Well I guess I am one of the "lucky ones" Im running a live wallpaper and have not run my battery down since the 1st day. Right now Im at 40% life and at 15 Hrs 30m since unplugged. This is with checking facebook, twitter, email, phone calls, internet browsing\video watching and following the steps for the GPS fix. The only thing I have done is install ATK on the phone, besides that its all stock.
One thing I know is a huge battery drain is Time without Service. Check that stat and see if you have anytime at all without service, if so, I am pointing to that as a major drain on the battery. I know currently I have 0% Time without signal, my fiancee however is usually in the 20+% range and her battery drains like many reports I have seen here (she has an EVO).....
Yesterday I only managed 16 hours. Web, Email, A bluetooth file transfer, short bit of gaming. I have about 5% of the cell standby time (26%) without signal. My girlfriend has the Aria which is running Android 2.1 also, has all sorts of widgets, haptic feedback on and can make it at least 24 hours. I get that it has a smaller screen but it is also an LCD. Shouldn't the Super Amoled be saving our battery some display consumption.
i get about 14 hours or so moderate usage and at the end of the day, i have about 35% left at night.
If you detail the "Display" usage in the battery usage details how many minutes has your screen been on? Mine says 1hour 2mins ...this is for 8 hours of running time. My display is using 50% of the battery (which is at 68% now).
W00t W00t today I have reached a new high 2 Days 6 hours and 29 minuts with 12% battery left.....
What I have found is keeping Wifi on while I am at work and home like almost doubled my battery life. Which is great that I can use Wifi all day and not drain the battery so fast like my Fuze. Right now been off charger since 7:30am and I have 84% left. Yesterday after 9 hours I was still over 50%. For me its better than any other smartphone I have owened.
I used manual brightness, (swipe notification bar), turn off GPS/BT. black wallpaper and set Wifi to never sleep. Also the power saving mode in settings is off for other reason and doesn't affect battery.
At 18% right now and it's been off the charger for about 30 hours. I noticed yesterday that while I was connected to wifi at home (with Y5 app), it was draining faster than when I was connected to 3g. Did some tested back and forth and JuicePlotter clearly had a noticeably steeper downward slope for when wifi was connected than when it was using 3g. Weird :\

battery usage normal?

When in standbye overnights my phone goes from 60-70% to totally flat, I use battery monitor and I notice the phone use -100 till -200 Ma while I don't have any sync going on?
Somebod else with monitor app please give me our numbers
I have noticed tha cpu works (without any app loaded) about 35% -45% with no reason...that eats battery !!! any other have noticed that ?
I can make a video to proove that !!! Maybe with 2.3 the resoults will be better
I will give you my experiments:
First night(GMT+3 timing):
from (2-3)am: Wireless on, battery percentage still 19%
from (3am-4pm) wireless of, battery percentage is still 19% !!
Second night:
from (9am-5pm) battery percentage was 99%, when I wake up there were two missed calls and the battery percentage was 90% !!
Third night(Last night):
from (9am-6pm) battery percentage was 70%, when I wake up there were one message and the battery percentage was still 70% !!
* It is not nights, these days I actually sleep in the morning, and the timing doesn't mean I sleep all that, but before going to sleep I use my laptob.
I had the same issue in the first few days. I dont know if you installed some apps, but after I deactivated "green power" (for saving battery life) the battery lasts very long in standby mode.
so deinstall apps which say they would save battery and close all apps (browser etc.) before you sleep.
I dont know if the app was responsible for that or just the battery which needs a few days to generate 100% power.
Had mine for 2 weeks now, battery lasts 10 hours from 100% to dead, same as my Desire did.

Battery monitoring and optimizing apps did suck most of the juice out of my battery. Deleted all,my battery easily makes 12 hours now

I don't have any numbers but my phone goes from 100% to around 93% to 95% overnight depending on how many emails I receive while it's in standby.
About the same as my old Galaxy S.

That sounds great!
My Galaxy S2 would lose 30-40% overnight with a few emails...
I can't wait till I get my O3D.

[Q] Battery health test: Do I need a new battery?

I have had quite bad battery drain issues for a while, and searched BBS dump files and forums for an answer, but the logs appear normal with no unusual wakelocks. In short, the battery consumption profile is OK but it just goes too fast. So I concluded I needed a new battery and was too cheap to buy Samsung original battery and instead got a noname type (same capacity, 1500 mAh).
But it didn't help. Still 12-16 hr standby with low use (<1 hr screen time at lowest brightness).
So I tested the health of the two batteries by draining them as fast as possible. I used the app "Battery Drain" (https://play.google.com/store/apps/details?id=com.fuzzyoneapps.BatteryDrain) and drained using full screen brigtness, wifi, bluetooth, gps, CPU but NOT the vibrate function.
The results are attached to this post. As observed, there's no big difference between the two batteries. And I don't know what to expect.
So now I'd like someone else to do the same test so that we can compare the results
Basically, just 1) Run the app with all the settings turned on except vibrate, 2) make note of battery percentage, 3) leave it for exactly one hour, and 4) check percentage again. Is ~45% per hour normal for the nexus s?
Thanks in advance

Incorrect Battery Life Meter

I have a Samsung Galaxy Note 4 running 5.1.1 and have been experiencing incorrect battery life measurement. My battery meter will say I have anywhere from 15-35% battery life left, then the phone will shut off and restart, when it comes back on the battery meter will now register 0-1%. Any reasons why I'm experiencing this issue? And are there any known fixes?
Buy a new battery.
I am experiencing a similar issue with my older note 4.
I have a year old black note 4 and a newly purchase white note 4 and I noticed something strange.
The black reported 50% battery remaining, the white reported 80% remaining.
I switched them off, switched the batteries and turned them back on.
The white then reported 40% battery and the black reported 91% battery.
Seems like the black is always reporting around 10% to 15% more than it supposed to and when it reaches around 20% it suddenly drops to around 5% and there is a rapid drain until it shuts down.
Wondering if there is a way to fix the internal gauge or something....

Mi 11 lite (miui 12.5.1) battery drain while idle

Hi all,
My phone drained 14 percent battery yesterday while idle for 9 hours. The interesting thing is when i add the mAh usages that i see in battery and performance tab it only adds up to 6 percent battery usage. ( i calculated and confirmed with time that 40 mah is aproximately 1% battery)
Also this morning i am seeing an unusual drain as well while the screen is on, it drained 5% but it should have draned only 3% because it says it drained 138 mAh.
Does anyone have any idea about this problem?
This also happened 2 weeks ago and the only thing common both days were, i charged my phone slower (charged using usb on the car) instead of using fast charging.
I also leave the screen shots that shows the battery usage.
Put the phone into Airplane mode when idle: this may save some battery.

yes of course but the battery drain I explained sometimes happens I actually think its a battery indicator bug. Because it shouldn't be draining this much battery because it doesn't show any unusual drain on battery information screen contradicting the percentage lost (14% battery was drained but according to battery information screen it should be 6%)
