the most annoying problem in canvas hd is the battery drop problem.
For some users the battery may drop all of a sudden from 34% to 12% while for some it may be different. For me it was always 34% - 12%.
Now the one important thing that I observed was that when I used to charge my mobile , the charging jumped straight from 76% to 100% . In my view the battery was never charged for the last 20%. And it was this 20% that appeared as the sudden drop.
Now coming to the solution..
Battery calibration and wiping batterystats.bin actually never solved the problem because I tried both.I don't know if changing the Kernel did.
So I have come up with one solution that won't disappoint you..
Follow the steps..
1. Let your battery drain to below 10%.. say 8% ..
2. Charge your battery like u always do..
3. When the battery reaches 100% , do not disconnect the charger, go to System settings and then battery and check the graph..(don't disconnect the charger because doing so will reset the graph).
4. notice the sudden increase in battery charging.
5. Use the phone as u always do and let it discharge to 70% ..
6.Here comes the LIFE SAVING STEP..Now what you have to do is charge your phone in one go..there should be no interruption in charging..If the electricity goes off even for a second..the whole process fails..so prefer using a UPS..
7. Let the battery charge to 100% and use normally.
8. Its my guarantee that the battery drop is gone.
The bad part..
The problem reappears after a reboot.. and we have to repeat the procedure again.
Come on , Don't be PANIC about sudden drop ,First of All letting the battery drop from 100% to 1% leads to fluctuation in battery volt,be aware about it ,Don't use your chd while charging is most important ! if you may use your chd normally like noob users who only use fb.watsupp etc whenever they need ,it won't drop like 30-12% ,fast drain made by users leads to bloat of battery ! high volt ofbattery from 90-100% has corrosive effect if you drain fast then your battery would PREGNANT or fat or swell
DON"T PANIC USE YOUR DEVICE AS A PHONE

If I keep my phone on charging even after its on 100%, it starts rolling back. As in from 100 to 99 then 98, even if its pluggen in.
Don't know what kind of a problem this is, hardware or software.
Or there's some issue with the battery.

But usually I put it on charging at night before sleeping.
And when I wake up in the morning, the battery % becomes even less than what it was when i plugged it in.

Maybe You have some program that syncs something all the time. Did You try to turn off data and wifi. You can always check it if the reason is the hardware or Software. Just make a backup of Your whole ROM, delete the data and leave the phone over night. I hope it is only software problem.
EDIT: Does Your battery go hot while charging? Oh, and try to wipe battery stats

The x10 charges the battery to full then if still plugged in it will stop charging until batt drains to set level ,then will charge to full again and over and over all night. X10 wont over charge batt when left plugged in. Kernel/bootloader handle this. There is an app current widget that can log charge levels.
EDIT: I had a tip on charging here but removed it after further research read more about batt here..

EDIT: the best tip I usr for battery life is, let batt runout until phone shuts off, then pull batt, then plug in charger, then replace batt into phone, then phone will boot, enter xrecovery on first boot and wipe batt stats. After wipe while still in xrec pull batt then unplug. Now plug in phone then insert batt. Phone should boot in charge mode( big batt icon only on screen) dont start phone untill light green for 1-2 hours to get full charge . I do this about once a month, when phone starts to shut off around 15%

As mentioned above as well, this is normal. After charging to 100%, the phone stops battery charging, and will activate charging again only when battery falls a bit (say 97%). Also, battery heating while on charging (and also when using the phone continuously while playing a game) is normal. Relax.. your phone is fine
@ToledoJab
I am having the same issue with battery... phone switching off at 15%, even at 22-23%, when playing a game or something. But switching it back on, and leaving it idle, phone might run for another 2 hours. So it is the extra load while running a game that the phone cant take any longer (i remember getting the 15%,10% and 5% reminders earlier while playing games)...? Does the battery calibrate method actually help in your case? does it go all the way down to 0% or 1% before shutting down.. ?
I just did this after posting that. And yes my phone reported warnings @ 25% 15 10 5 and then shutdown @ 1%.
This way is like reconditioning an old rechargeable ni-cad batt.
All this does is completey drain batt then, with least amount of drainage (phone on, apps& radios running) allows battery to full charge.
There is also a way called recalibrate battery. But this way over charges the batt.
EDIT: I think the phone load will effect reported batt left. I think batt gage use average loads to estimate remaining power. Meaning games, full brightness of LCD, radios -3g -GPS -WiFi -Bluetooth will use more than avg power
edit 2: I found this thread also has some very good points and links. after reading this i will not intentionally take my batt to 0%. I hit 0% about 1-2 times a month on accident as it is. i will just make sure when i do go 0% to wipe stats (dont know if it helps or not) then preform a long (overnight) full charge with phone off.

First and foremost...lets get this out of the way..if u want more battery life..get a newer more powerful battery...thats the best option..
But if you still wanna stick with your current battery and still want improvements..here is a little something i want to tell you..
Obviously you might have searched about how to improve and come across the method known as calibration.. this is the method as described by one of our members..
nickrule1896 said:
Steps:
1. Before flashing a new rom, use root explorer (with read/write set) to delete the file "batterystats.bin" stored in /data/system/.
2. Charge your phone with it being turned off.
3. After it is fully charged(100%), take out its battery without plugging off the power supply.
4. Wait for a few moments, and a ? sign will appear.
5. Put your battery back in. You should see that the battery percentage increases quickly to 60%. If it increases to 100% with seconds, please skip to step 6.
6. If it stops increasing at 60%, let the phone continue to charge until 100%(takes quite a while)
7. Once it reaches 100%, let it charge for a further 15-20 minutes.
8. Once that's done, you can boot to OpenRecovery and flash your rom!!!
Alternative way of calibration(thanks a lot zeppelinrox!!!):

https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
As is mentioned.. "It has no impact on your battery life" !!!
So...BATTERY CALIBRATION IS JUST A MYTH!!! Still...if you dont believe me..continue following your stupid practices..
Coming onto bump charging...
When your phone shows u fully charged it is actually charged only till 90-95% and thus u may experience a sudden decrease in battery %age after u unplug the charger...
The method for bump charging as you ardent ritualists may already know is as follows..
" Phone on, charge to full
Shut Phone off, charge to full
Phone back on, charge to full, use like normal. "
The main disadvantage of this is that it increases your battery voltage...Also in some case of sudden overvoltage while charging this can damage your battery...what for? 5% increase...
also..all that extra heat is bad for the lithium batteries...
Therefore 95% battery is good enough for daily use
so..if you really want to improve battery life...dump all these methods and just buy a more powerful battery and give it a month to give you proper results..all new batteries require at most a month to work to their full potential...
P.S. : come to think of buying a new battery...this idea may be very helpful to you if you do happen to own a Galaxy NOTE..

If this is all a myth, and I'm none the wiser, why is my battery percentage all over the place? For example, went on a hike listening to music etc. Ran the battery out. Got home, plugged into charger, turned on and it said I had 46% though when I first plugged it (while off) the battery symbol showed obviously barely anything.

Android is very....insensitive when it comes to battery .
Android keeps track of the battery using a permanently running Battery Service , which polls at a certaon interval....
For our phone , deep sleep will affect battery polling and thus your battery will be displayed as being larger than it really is .

Heyy guys I have a problem regarding the battery life on my fone
On any rom be it cm7 cm9 or cm10 whenever i charge my fone to say for eg. 65-70% and unplug the charger battery starts draining quickly until it reaches a particular point like (45-50%) then the drain becomes somewhat stable
However when i charge the phone fully (ie.100%) the battery depreciates economically (like on stock)
This means I have to charge the battery full in order to prevent for drain
What should i do to prevent this from happening? Or should I buy a new battery
Any Help Appreciated
In my experience with any lithium battery not just android increase battery life by let it die fully so it wont turn on at all then charge till 100% and no harm done by leaving an extra 20 mins leave charger in while turning on should vastly improve an older battery

I am afraid you're wrong in letting old batteries to drain completely man...when battery is new like say within 150 cycles what you said is true but as it becomes old it's better to charge it when it goes below 15...coz the chemicals will become inactive and won't be efficient in taking up charge

What about Die Hard Battery Caliberator? Got me rid of bump charging.
Hi!
I don't know why and how but I think the battery of my phone died. My phone is about 1 year old. It is fully charged then I remove the charger and then I start using my phone for about 15 minutes. After it the phone turns off with the reason battery is down. I plug in the charger(phone off) and it starts charging from 60-70 % and after about 30 minutes it says "Fully charged". Then it starts from the beginning. I tried flashing other ROMs, wiping battery stats... I think the detection of how much the battery is charged went wrong.. So if you guys could tell me another way which can maybe help i would appreciate it.. or the last chance is taking it back to service.
Thanks in advance!

I think you must buy a new battery as the same thing happened with my friend and he bought a new battery and the problem was solved.
otherwise check if your battery has any leakage
if it has leakage then replace the battery immediately with a new one.

Thanks for your reply! Don't you know maybe if guarantee covered the battery change?
The battery is old
Buy other
Or try calibrating
For future reference, the battery only indicates 100% but it's usually not 100%. I forgot the term but the reason for this happening is because the indicator
jumps up to 100% when it's actually (let's say) 95%, when it reaches to 100% (for real) it stops charging and will let itself discharge until it reaches
a point where it starts to recharge again. During the whole time it will say 100% even though it's discharing or recharging, when plugged in.
So therefore when you unplug it and it shows a lower percentage after awhile, that's when it is actually showing you the "real" power left.
("real", since the indicator isnt quite accurate anyway)

As you are saying that your mobile seems "hot"
First you need to confirm that its charger/device issue or only with battery.
First do battery calibration with this method: (In this method you need custom recovery for your device
This may help you

IMPORTANT: You can skip this step>> "Wait 20 min after you are sure it is 100% (phone should stay plugged in)" - As i dont know much about LG devices and their batteries
Now some advice from me-
If you can cover it >>> Never charge battery again and again before 15 or 20%
Always charge your battery to 100% at once and use your device till 15% or less than 15% and then again charge it full and so on...
This will make your battery backup good as well for battery life

According to the Battery Doctor app, you shouldn't leave your phone on charge for more than 9-10 hours(MAX), otherwise it WILL harm your battery.
You should try hibernating some of those apps with Greenify.

Use better battery stat (check play store) or similar app to track draining application.

I also have this type of problem when my phone completely runs out of battery and when plug it in charger it bump to 48%.
I dont the reason behind it that why it happen and whats the reason behind it.
If you have recently rooted your phone and have flashed custom rom in your phone than you may face problem of mis-calibration of battery. For solving this download a software called battery calibration apk ( google it ) . Your phone must be rooted if you wana use that app. but before you calibrate your battery make sure you charge your phone to 100%.
when you 100% open that app and grant the super user permission. Click on calibrate.
what the app does is that it will remove batterystat file from our phone and automatically it generate a new batterystat file in your phon. Thus any faulty or mis-calibrated file will be removed and you will get good battery life.
after calibrating do some cycle charge mean from 100% to 0% and from 0% to 100% without interuption. Do it for 3-4 times and you will see a drastic change in your battery life.
Calibration of batteries is a myth, battery stats is cleared every time you unplug a nearly fully charged device. Also draining modern batteries to dead is not good for them at all so I'd discourage it unless necessary.
