After charging my battery fully to 100%, I unplug it from the charger and without even turning the screen on, the battery drains to 92% within one hour. I check the battery stats and there are maybe only a couple wakes during this time.
Sometimes, the battery shows a certain percentage longer than others. Example, my phone will be on 65% longer than it would be on 60%.
Battery still gives me a solid 2 days usage with about 3+ hours screen on time. The service menu also says that the battery is good.
Is there a way to get the battery reading to show more accurately?
Thanks,
Hope I could Help You
For your battery problem, I guess you could try calibrating it. And also try to install "Greenify" along with "Clean Master or 360 Security" and try to close all running apps before turning off the screen. I also turn on Stamina Mode when the battery is at 100%, in an attempt to further save battery life. And the result has been kinda meh, but well, battery drains about 1% per hour. It lasts about a day and half with light usage. In my case, light usage being, browsing, youtube videos for about 2 hours, listening to music, social networking and taking some pictures

Hey,
im using greenify (my phone is rooted). Battery is quite good for me though. I get about 3 days with light usage. I start charging my phone again when the battery gets to anywhere between 10-20%.
I read that maybe its better not to let it get so low?
I have no wake locks either.
Umm.. IMO, 10-20% is okay. I usually charge the phone when the battery gets around 5%. I read somewhere that charging battery too early can affect the battery's overall standby time (reducing it). It's better not to let the battery reach 0% though.
I had that happen with my Samsung Galaxy Note 2 earlier. I once let the battery dip all the way to 0% many times. After a few charge cycles, I found out that the battery was dead and wouldn't charge at all so I ended up buying a new battery :-/
Umm.. Coming back to our Z1's, could you try putting the phone in stamina mode everytime the phone is kept on standby mode? This boosted my battery life a lot I even put my phone on stamina mode throughout the whole night yesterday to test the battery life again, and when I switched on in the morning, I saw that the battery had dipped by just 2% (standby time of 7 hours). I'm really confused how your battery drops so fast, 100% to 92%.
Could you try calibrating the battery and then putting it in Stamina Mode while on Stanby and tell me the results? I hope I could help :fingers-crossed:

Ok so this is what i noticed has been happening with my phone...
I wake up in the morning and i unplug my phone from charger at 100% battery life...
after about 1-2 hours of no use (outside of occasional check of time) and no programs running i notice that 25% of life has diminished...
i have turned 3g off and done most of the kaiser tweak settings that help with battery life. for the rest of teh day i can use the phone and battery life runs normally but it seems the first 25 to 30% drops real fast without use
is everyone experiencing this? is it normal?
KP
The problem lies in your first sentence. "I wake up in the morning and unplug my battery." You are charging your battery too much thus killing it's battery life. I only charge my phone in the day while I'm at work. That way I can unhook it when it's fully charge. I would go on ebay and type in OEM battery Kaiser. You can pick one up for 15-30 dollars new.
From what I understand. Leaving your battery in the charger when it is fully charged should not damage the battery as long as its not there for an excessive amount of time but i might be wrong. Either way i have no way of charging the phone during the day as im on the go most of the time so this would mean even if i get a new battery it wont matter because it wile eventually do the same as i have only used this phone for about 3 or 4 months now. any other possibilities or solutions?
or should i just take it as it is and just buy a new battery maybe a bigger seido?
I thought Lithium ion batteries have overcharge protection. I charge mine overnight which I am sure a lot of others do also with no negative effects.

I do... Maybe I shouldn't?
I would hope it has Overcharge Protection!!!
With NiCad Batteries if you overcharged them you would kill the life of the batteries.
And while all batteries do this LiIon are least tolerant. If you overcharge a LiIon battery, that is without Overcharge protection, the LiIon Battery with BURST INTO FLAMES! Thus the problem with the Sony Batteries that caused all those Laptop battery recalls.

Thats total BS with lithium batteries.
To the OP: Try running down your battery completely once, until the phone switches off by itself, then recharge fully. If you never do it and always recharge before the battery is empty the battery's power meter can lose its calibration over time and display weird things.
If it doesn't help, and you can notice a drop in overall life time you might need a new battery.
I have the exact same "problem" with my Tytn II.
Is slows down evenly though. (So the first 5 % of battery vanishes in minutes basically while the last 5 % can last for an hour, when it's half full % will last somehwere in between these two extremes).
Personally I've just interpreted this as poor measuring done by the hardware and/or software. (Ie I don't think the battery performs better the less full it gets as the meter in Windows would have me think)

Hmm...I don't see how turning my phone off to charge would increase the charging rate dramatically. My phone in standby mode uses 1% every 2 hours.
depends highly on roms and especially on radios.
with a crappy rom, battery could drop as fast as 10% per hour.
with a decent rom, battery drops in standby mode at a rate about 2% per hour.

If the phone is on but on standby that barely changes a thing. If it's on, with display illuminated then yes it might take you an extra 20 minutes to charge.. no big deal either.
*UPDATE*
ok so i drained my battery last night completely(turned on navizon, tt7, and skyfire) which took me about at most 2 hours.
Put it in for a charge
woke up at 9 and checked to see and it was 100%
I have push mail set to update every hour and i also run pocket sportscenter autoupdates which updates every 10 to 15 minutes
I used the phone for 5 minutes of calls
5 minutes of web surfing
a few text messages
and the occasional time check
at 6:30 pm battery life was at an amazing 90%
i was thrilled.
i continued to surf the web heavily from 730 to 8
a few more text messages
at 9 battery was at 67%
so i gotta believe that draining the battery helped recalibrate it...
i guess every 2 or 3 months i got to drain it out and give a full charge
thanks for the help guys
really appreciate it
I'm trying to nail down if this is normal behavior or not my phone always shutdowns itself when the battery level goes below 7%, no matter what.
then I turn it on it boots and shows 0% of battery left then it shutdown again, next time I try it's totally dead.
Tried with a battery calibration improved the overall battery life but that mark is still there.
Is that normal? I mean when I used to have a G1 it lasted until 1% or so.. 7% can be very well an extra hour of usage that I'm loosing.

I've noticed the same thing. It'll be interesting to see if anyone has a solution.
7% of battery life is just a number. It could very well be inaccurate, and simply reporting 7% when you actually have 0%. When you reboot and it shows 0% just backs this idea up. You are not "losing" an hour of battery life, you simply never had it.
To check this, use spare parts to look at the voltage of your battery when it approaches 7%.
Also, this belongs in the QA section.
I'll give it a try, interesting is the fact that both Cyanogen RC3 and Battery Monitor are reporting the same thing.
Will keep an eye on the voltage, what should it say ? something near 0?
seriously?
AFAIK li-on battery never be below 5% or 7% why?
because if you get below of this the battery will be dead and will not work anymore. so thats normal.

I've also read its normal but if its normal why isn't it calibrated to show 0% when its actually at 7%? My phone goes off at ~10%
btw there are so many battery threads lately.. http://forum.xda-developers.com/showthread.php?t=702167
Yeh, mine also goes off at around 10%.
it seems normal then , time to get myself a spare battery ... travel can be painful if no power outlet / usb port is near me
Yes its kinda normal. My phone has always shut down at 8% from day 1. I think its because of what we're talking about in the battery cal thread personally.
Hey all,
I have had terrible misfortune in the realm of battery stats. Ever since CM7 (and maybe even before) my phone is unable to figure out how much battery is left. Here is a common scenario:
Charge phone overnight, use phone throughout day, battery dies after 6-7 hours of moderate-heavy usage. I plug it in, reboot, and then it reports ~60% battery left.
Another common scenario is that it will dwindle around 5% battery or less and go up and down until it finally dies.
I know that this is a misreading of the battery and not battery drain or a rogue app because when I flash a new ROM the battery life is amazing for 1 day. The day after I flashed Team Hacksung's ICS rom, I got almost 17 hours of battery life with 2.75 hours of the display being on and 30 minutes of Google Music. I was blown away! But even then it was dwindling around 5% not knowing when it would actually run out. The day after, it was back to its old tricks of misreporting the battery percentage.
Today I charged it to 100%, unplugged it, and shut it off. Then I plugged it in while it was off and let it charge to 100% again and wiped battery stats in Clockwork mod. I'm getting ok-ish battery with that, but it's not even close to how good it was when I first flashed ICS.
Anyone have any ideas what I could try?
Thanks!
When you wiped the battery stats did you let the battery fully discharge and shut off before charging again?
After wiping battery stats it is recommended to let the phone fully discharge to the point where it will automatically shut off.
Keep in mind with the age of our phones, it could just mean your battery is dying. Try the above method, but in my experience uncalibrated battery only last a few days. The phone will "fix" it by itself the longer you use it.

That's what I'm doing currently. Battery life seems improved, but we'll see what happens. It's nearing death now, ~6%. At this point it will probably misreport it for a few hours until it finally dies. I left it unplugged overnight, so now it's at 19.5 hours uptime with 1.75 hours display time.
Definitely improving! I hope that it successfully recalibrates.
Battery stats have nothing to do with how the os calculates remaining battery...they are what is displayed in settings>about phone> battery use and are reset each time you charge to full.
You're just giving it a good bump charge...wiping the stats is just a placebo effect.

Seriously? Wow I didn't know that. Is there a way to actually reset how the OS calculates the battery?
Does this app do anything?
https://market.android.com/details?...xLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
Nope...that app is just perpetuating the myth of what the batterystats.bin file does.
Don't hate me for this but, Then how come Roms usually give me better battery life after a full cycle? not bump charging or deleting battery.bin just running it?
Because the system for tracking the remaining power is getting to know your battery. once it gets a feel for it, it's more accurate. In theory anyway
So the "give it a day" is still true, at least in theory?
Sure

battery gauge temporarily fixed by removal and replacement of battery
Ever since I rooted my phone, I've noticed that the battery gauge/meter is way off. I keep an eye on the charging voltage and try to pull the plug around 3.92 volts. Problem is, the gauge is always reading low until I pull the battery, wait a few minutes, and then reinsert and boot up. Then it's fine for a while, but I notice it creeping down even though I keep topping it off with a charge to keep it around 3.92 volts.
What's going on? Do I have to fully deplete the battery and charge to full to have an accurate (or somewhat accurate) battery gauge? Do I have a bad battery (this battery has been used only a couple months)? Is something else going on here? Recommendations, studacris? Doesn't the os use battery voltage to calculate state of charge (%)?
Can someone help me figure out where and why my battery is draining! I have tried everything yet can't figure out a way to reduce the drains. There is no change in estimated battery time on activating stamina mode and then stamina mode along with low power mode. Right now,against 64% battery it says 15 hours remaining. This is very bad. On deactivating both battery saving modes,i have only 5 hours of back up. What to do! I have attached battery usage statistics if that helps.

If you have just updated to the KK version wait a day or 2 for the battery calibration that can cause that.
Most of times it's due to 3rd app not updated to the KK version that ruins the battery when that try to access to the SDCard.
I've had exactly same problem and i thank really much gregbradley for the solution. I've revoked the SDCard write permissions (it's this case by default) i can't write to it but i haven't anymore the battery drain and overheating problem.
So if you have used the fix to have writing permission to your SDCard then you have the solution.
Looks pretty good

Did you charge in between? 1 day plus and still 63% is very good, if you have not charged in between. Regarding the prediction about 15 hours for 63%, take it with a pinch of salt. Check the actuals and see if it really is 15 hrs. Then we can check what is draining the battery. I think if you use it the same way, I see no reason why it should not come for another day..Currently there seems to be no reason for any alarm.
Just my opinion.

I did charge in between hence my problem. One more thing i noticed was that on switching off stamina mode and switching on low battery mode at the same 63% shows just 4 hours of battery backup. Whats up with that! Thinking about factory reset. Any suggestions?
When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the BLU R1 HD's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
Good very small drop while not being used, even when loaded up with apps.
I experience pretty bad battery drain on idle. Basically, if I leave my phone alone without turning on the screen, it would be fully drained in about 30 hours.
I've reset the phone many times but phone idle always remain as the top battery draining app. averaging about 100 mah per hour constantly.

Exactly this! My phone uses more battery while on standby than with the screen on watching things! I don't understand this behavior. Powernap + Greenify + Amplify doesn't solve it either, even the things that keep it "awake" are hibernated and also delayed by Amplify. Wakelock detector doesn't even detect any apps that are running during standby either. Also, I have no bad signal because it is always on full bars or 1 less than full.
If anyone figures it out I would love to know how to solve it.
I get this too. Im trying to debloat the rom of some apps that seem a little suspicious. Will do this tonight. Already backed up my current system partition in case I break something. Wish me luck! :good:

Me too. And I have debloted OEM rom to what I consider closest to slim or stock. We'll see later how it goes.
i've pretty much ran the Prime version debloated or the OEM debloated, same thing. I think it has to do with the phone radio and Android 6?
When I put it on airplane mode with only WIFI turned on, phone idle isn't as bad.
Maybe its kernel controlled? Have u tried flashing the 6.6 updates radio.img? Does it contain one? I only used prime to power on the phone from then on only OEM version debloated. And as you say its always consuming batt on idle. I'll give airplane mode a try today.
Alright, I have just installed the xposed module "MobileRadioActiveFix" so this will confirm if it is in fact the data that's impacting standby battery. However, not too sure because "Intelligent Battery Saving" does disable data over time and the draining is still happening in that mode.
Anyways, I'm going to be testing this and report back. @l33chpda @Alex_XV6700

I figured it out, I was monitoring the CPU states and the CPU is not using a hot plug. It nevers makes a core go offline even when the screen is off and it will ramp up while the screen is off because there doesn't seem to be a cap when the screen is off.
I think the only way that we are fixing this is if someone makes a kernel with a hot plug in it.
With Prime 6.4 mine lasts a month on Wi-Fi.

Yes, it doesn't make a difference. I do consistently get 4-6 hours for every two days, however, I can get more if the idle battery life is not there. For example, with your chart, my idle time would be about 45%-55% above the screen.
It's just the way it's reported in this ROM. Instead of looking at the battery stats, just look at the actual battery life of the phone, which is fine.
I have stock V12 vanilla ROM, and I find the standby drain can at times be worse than when I'm using the phone, and I'm not sure why. I'll put the phone in airplane mode and put it to sleep right after unplugging it from charging overnight and when I check on it in an hour or so it'll be down from 100% battery to 90%. When I turn off airplane mode and use the phone normally from that point on, battery drain is normal.

Yes, I experience the same thing! However, overnight, it drains about 10%-20% even though looking at the stats it is not even awake! It should only be draining about 1%-3% because it is not really doing anything at night.
Even the screen uses less power than the standby. @waingro808 could be possibly right that it is just reporting the battery stats different, however, on other phones with the phone idle, that percentage is very low and not as high as ours.

The battery stats dont add up either...
As you can see in my screenshots Im still 14% on battery
And it states that between SOT and Idle I have consumed more than the 2500mAh that this phone has on the battery.
