I charged my Samsung extended battery to full then reset the battery stats but my battery reporting is still terrible after 3 days. As soon as I unplug it from the charger it is automatically at 98% and drops quite rapidly.(~3% every 5 minutes of active use)
Would allowing the battery discharge to automatic shutoff alleviate this problem? That hasn't happened naturally yet
That can be normal behaviour. Mine does it sometimes too. 95% and up on any phone will be that accurate. As for your drainage problems, your phine is doing something heavy duty in the background. And/or you are running full brightness. I am getting 4.5 screen time on average. I was able to get over 5 hours this weekend. For me to get 3% every five minutes i have to be playing a game or been downloading a large file over cellular data.

Seems like you either have a bad device or you have an app or two that is killing you. Something that gets push notifications for example, like a messenger or something similar

I have been experiencing this as well, my stock 1850mA battery seems to outlast my extended 2100mA battery by about 20%. Has anyone else seen this behavior? I have been thinking that maybe I got a bad battery.

I have just installed Battery Monitor Widget as recommended in a battery related thread in this forum, and it is showing my extended battery as having 1750mAH. I don't know why and I'm not sure what to do to fix it, and my battery life is pretty awful.

Battery Monitor Widget allows you to manually change the battery capacity.
Touch the gear symbol, select ""Monitoring", then "Battery capacity". Enter 2100 if you have the CDMA extended battery.
Yes, I saw this - but if it's getting the capacity from the phone, and the phone is reporting 1750, isn't something wrong? Doesn't that mean it will stop charging the phone prematurely because it thinks it is at max capacity?
In fact, I just remembered the stock battery is 1850 mAH so I have no idea where the 1750 is coming from...
Thanks for your reply.

its coming from the GSM version because it has a 1750 mAh battery.
battery monitor widget is not pulling from the chip inside the battery, it is just guessing your capacity because it knows its a galaxy nexus. hence you have to manually enter your correct capacity into battery monitor widget yourself.
also remember this fuel gauge is not capable of giving current readings. so battery monitor widget is guesstimating current based on extrapolating the drop in your percentage among other tricks the developer uses.
Thank you very much for your reply. It makes sense what you're saying, I took the setting in BMW literally as it states:
"Override capacity provided by phone"
Thanks to both of you for the help. Now I still need to find out why my battery life is sooooo bad...

I was looking on the market and there are a ton of battery widgets out there. I am looking for something that can tell me how much juice I have left but also one that can give me an estimate of how much longer the battery will last before charging after it has gathered some stats. I saw 2 that people were using called battery monitor widget and one called battery left widget. I am looking for something similar but with the lowest overhead in terms of power and cpu usage. Which of these 2 would be better or is there a different one that would be recommended?
Just for the Battery Stat montioring, I would recommend 'Battery Monitor Widget Pro'. I've been using this since I had Android. Working flawlessly and providing lots of widgets. I'm not sure about another one but so far batter monitor widget is the best one from lots of battery monitor apps.
Won't be disappointed.
I use Battery Monitor. I like the little fuel gauge widget it comes with. Pretty cool.
I've been using Gauge Battery Widget for a while and like it pretty well.
thanks for the suggestions.
Here's another battery problem thread guys,
Here's my scenario:
My d2att is rooted and has CyanogenMod 10.1.3 Stable running on it. Nothing has been tweaked in terms of bloatware since CyanogenMod is pretty good about not putting crap on their ROM.
I have a stock 2100 mAh battery from Samsung and a 4200 mAh battery from Hyperion Electronics.
I decided to run tests on each battery on two separate nights to see how they ran. I did this using BetterBatteryStats under the same conditions. I charged each battery to 100%, disabled all radios including GPS, sync, wifi, NFC and Mobile Data and left the phone on over night in a span of 8 hours.
Night 1 - Stock Battery: 100% - 40% in a span of 8 hours with BBS reading "mmc_camera" as the main culprit for battery drain.
Night 2 - Hyperion Batter: 100% - 98% in a span of 8 hours with BBS reading "AudioOut_2" as the top partial wakelock.
My questions are 1) what is "mmc_camera" and why was it keeping my phone awake? and 2) why is there such a dramatic difference in battery drain between the two batteries?
Before anyone tells me, "because the second battery is substantially bigger", I know this. It's essentially 2x the amount of the stock battery. However, based on simple ratios, if the battery is 2x larger than stock, why is the Hyperion battery only draining 1/30th as much as the stock? That doesn't make sense.
Someone please let me know what they can tell me about my problem because I'm seriously sick of trying to power manage my smartphone.
I have noticed this as well it makes no sense? I have the same exact problem you are seeing.

Try to make sure your front camera sensor is disabled, there's some settings that have the phone look through the camera to see if you are going to wake it up.(something could be in motion settings.)
Or reboot and run the test again. Sometimes the phone glitches out if not rebooted.

is it just me or is the kitkat ROM really sucks----battery pretty well?
I also notice that the CPU usage does not drop to 20 percent idle but when I used other ROM (JB based) it becomes 5 percent.
RAM usage is good but I think it hogs the CPU. I used cpuz on measuring the cpu usage

Where can I get the JB rom for OGP?
For me, Android was best at JB and went backwards with KK.
Yes, I've noticed absolutely horrible battery life with KK. KK just feels like it is several different parts all just thrown together.
The only reason I think is that theoretically JB uses more battery is that the system uses more voltage than the kitkat. however, what's less voltage use if the CPU is always busy and wakeups are just everywhere.
Hi guys, maybe you could post in some battery stats so we could know more about whats draining your battery in particular and suggest some fixes. I've actually experienced the opposite with kitkat-battery life for me improved. There was even an instance that I got the phone to last 30 hours, with 5 hours, 48 mins. screen. On another instance I got 15 hours life and 5 hours 25 mins screen on. I just lost the screenshots as I had to reflash stock when i was doing some G3 mods., but nevertheless i could post some new ones.
I value batter life was well and i'm curious to see how yours could be improved too..

What a battery life. 15 hours screen time?
how can we accurately measure? because I only use CPU-Z and installed DS battery saver to save power. right now it only used 2% of my battery during the night. (from 1:45 - 5:50am)
I see. can you tell me what app should I use to determine CPU usage of each app/service?

No, my battery lasted 15 hours, and my screen-on time (total time i spent using the phone) was 5+ hours coz i basically used my phone then for gaming the whole day I suggest you download gsam battery monitor app (it also has a temperature_bat. Usage graph), as well as wakelock detector. Another alternative would be better battery stats. What you would need to observe would be the apps and wakelocks draining your battery both when you are using your phone, and also when its idle.
I also notice that battery capacity is 2A in which it should be 3.140A right?
this shows on kitKat but on jellybean, it's 3.140A again.
is there something wrong with the detection of battery capacity?

What happened was that in kitkat, the permisssions required to be able to access battery stat files changed. Thus, apps w/c could freely access the batter stats in JB cannot gain complete access in Kitkat. This is the case for some battery monitor apps w/c now have lesser accuracy in reporting battery. No worries though, as there are means to bypass this problem. If you have xposed you could install a module for this. Also, some apps like gsam battery monitor come with a separate root companion app. Once you install those batter stats will be accurate.
Here's a screenshot of my battery stats for today..might not be 5+ hrs of screen on as i did a lot of rebooting today (themed with g3 tweaksbox). Nevertheless, this is just to show that kitkat has the potential to provide good battery life. Also enclosed is a screenshot of one of the battery apps i use, gsam.
Hey everybody! I have some findings I absolutely must share so you can benefit as well.
I've been doing some tinkering and I've find a way to significantly increase battery life on the OGP.
First thing you'll want to do is put your phone into airplane mode.
Second, turn your screen brightness down as low as it will go. I mean, all of the way down.
Third, don't play any games on your phone.
Try those three tweaks and see what kind of battery improvement you get.
Unfortunately, Camera has stopped.

Just so you know, first my cell radio and wifi were both on the whole time. Second, i was on auto brightness the whole time. Third, i played clash of clans as you see in there.
If you have not done this already, adjust your cpu to save your battery juice. Set the cpu governor to powersaver or interactive mode if you just using the phone to send msg and make calls. I let my phone run on msm-dvcs and when I'm not plug in. Check out ROM toolbox if you're rooted. Seriously folks, instead of complaint about how much the roms suck the juice, try these different ways to see they make any difference for you.

I've got a Tab S 10.5 LTE a few weeks ago, and I've been quite happy with the screen and everything. But there's this one problem where the battery gets drained to quickly; while it charges so slowly. While web surfing, the battery percentage goes down by about 1% every 2 minutes, which gets me about 30% down in an hour. This is completely different from the iPad Mini I'm having. It's probably because of the big screen it has.
Is this normal? Is there like a ROM or kernel or anything that can fix this?
Hi.
Install a battery monitor, GSam battery monitor is the one i use and does not affect your battery, it gives me a estimate of 16hrs of use on my 10.5" per full charge.
Install the free version of watchdog and set it in the setting to monitor all processes, then you can see which apps are using your battery the most, and then you can kill or remove the ones that are causing you problems.
Make sure to disable wifi, blue-tooth, gps and app syncing and alarms are disabled, as these all use power, or keep your tablet from sleeping when you are not using them.
EDIT: Also get an app that can monitor you tablets wakelocks, which means it shows any apps that keep waking your tablet up, instead of letting it go into a low power state while you are not using it.

Not sure which model of the 10.5 you have but if it is compatible, try the SkyHigh kernel. I switched to this a while back and can tell you the battery life is simply amazing. I can go now almost a week in standby mode without needing to charge it. When I do use it I can get up to about 6-8 Hrs of actual screen time on recorded. Depends on whether I am gaming or simply browsing the web. I am also running the IronRom custom rom, which is pretty debloated and comes with it's own kernel, but SkyHigh definitely gives better battery life without tweaking. I just took stock values and it's great. Highly recommend you try it.
Forgot to mention, I am still running KitKat. SkyHigh kernel is not available for Lollipop, yet.
It took me a while to figure this out but here is what I did.
1. Disabled WiFi when the screen goes off
2. Enabled the power saving option: disable background data
3. Screen timeout to 15 seconds
4. Enabled developer options and enabled the option to kill tasks as soon as I leaves them
5. Enabled the option: no background tasks
I am now on day 2 with 68% battery remaining. Previously the battery died in a day even without the screen being turned on.
No apps, no hacks, just simple tweaks
Try the Free Version of Juice Defender for a week, a lot of people swear by it.
You can only use the default profile in the free version, if you like it, then buy the pro version.

Ok, with all that said, I've tried most of them already. I guess it can't be helped as the screen's really big. But is there anyway to speed up charging?
Using Battery Monitor Widget and Galaxy Charging Current Free, the charge is only taking up around 1400-1500mA, which is 0.5 less than that stated on the adapter (2A).
My 10.5" charges at around 1800ma with the stock charger and cable, according to my "usb charge meter" see link, but only up to 80% which is normal for li-ion battery`s and then slow charge for the renaming 20%

My 10.5" T800 has a battery life of around 16hrs according to GSam , I uses my tablet at mostly at night, so my runtime figures are with a low brightness level.
Please post your tablet model number when you give runtime figures, add it to your signature in your xda settings.
The 10.5" has an 7900mah battery, The 8.4" has an 4900mah battery.
Also the LTE models will have lower runtime as the cell/phone transmitter uses some power.

Is it possible to disable the cellphone transmitter? I don't use the phone at all.
Just activate airplane mode from the drop-down list, I use that on my GalaxyS3 that i only use for playing music, you can still turn wifi off and on in airplane mode, at least on my S3
